Our 2025 Performance Highlights



			*Dividends as of February 2026

We had a successful year during 2025 in a number of respects:

•IDACORP achieved net income growth for an eighteenth consecutive year.

•IDACORP increased its quarterly common stock dividend to $0.88 per share from $0.86 per share, as a part of a 193 percent increase in quarterly dividends approved over the last 14 years.

•Idaho Power continues to focus on timely recovery of costs and earning a reasonable return on investment. In December 2025, the Idaho Public Utilities Commission approved a settlement stipulation related to the Idaho general rate case that Idaho Power had filed in May 2025, with new rates effective January 1, 2026, designed to increase annual Idaho-jurisdictional retail revenue by approximately $110.0 million, or 7.48 percent.

•Idaho Power's customer count grew 2.3 percent in 2025, and Idaho Power's megawatt-hour (MWh) sales to retail customers in 2025 were the highest in its history, surpassing the previous record set in 2024, reflecting continued growth in its service area.

•In 2025, Idaho Power’s reliability metrics continued to be among the best in company history, as Idaho Power provided uninterrupted service to its retail customers 99.97 percent of the time.

•Idaho Power’s residential and business customer satisfaction remain strong – in 2025, it was the highest ranked utility among peers in the segment for overall customer satisfaction in a third-party survey, and was the second highest in the segment for business customer satisfaction, and the second highest in the segment for residential customer satisfaction in a separate third-party survey.

•During 2025, several key projects achieved notable milestones, underscoring significant progress towards Idaho Power addressing peak capacity and energy needs in 2025 and beyond, including commencement of construction on the Boardman-to-Hemingway high-voltage transmission line project.

Executive Compensation Program Design Highlights

We believe strong performance by our executive officers is essential to achieving long-term growth in shareholder value and to delivering superior service to our utility customers. We seek to accomplish this by making the majority of our executive officers’ pay “at-risk,” meaning we tie much of our executive officers’ target compensation to our financial and operational performance. To be earned, a substantial portion of our executives’ compensation requires that we achieve successful results over one- and three-year performance periods. As an executive’s level of responsibility increases, so does the percentage of total compensation at-risk, which we believe aligns the interests of our executives who have the highest level of decision-making authority with the interests of our shareholders. Our executive compensation policy provides that between 35 percent and 85 percent of our executive officers’ total target compensation should be at-risk incentive compensation under the short-term and long-term incentive plans.

Corporate Responsibility Highlights

We plan and operate with corporate responsibility in mind, in addition to the financial aspects of the company’s operations. We recognize all decisions have financial, as well as non-financial, impacts on our customers, employees, shareholders, communities, and the environment.

We intentionally include corporate responsibility action items across four priorities: keep employees safe and engaged, grow financial strength, improve the core business, and enhance the brand. In addition, we view our commitment to corporate responsibility as furthering the company’s short-, medium-, and long-term business strategies to safely provide our customers

IDACORP, INC. 2026 PROXY STATEMENT iii

with reliable, affordable, clean energy while promoting a respectful workplace where all employees are valued and welcomed. We believe this commitment will also enhance long-term owner value and promote environmental and community stewardship.

Some of Idaho Power's corporate responsibility initiatives include implementing a wildfire mitigation plan, enhancing grid resiliency and reliability, and continuing to further Snake River shading and in-stream river enhancement projects. We have also engaged in voluntary carbon emissions intensity reduction over the past decade.

We are committed to the safety of our employees, customers, and the communities we serve. One of our core values is safety first. We believe that safe, engaged, and effective employees are critical to the company’s success and that the company’s record of safety helps keep our service to customers reliable and affordable. Reflective of our focus on safety, Idaho Power achieved its third straight year with zero employees requiring overnight hospital stays in 2025, while reducing vehicle backing incidents by over 40% and implementing a fail-safe capacity model to shift from reactive incident response to putting proactive controls in place that help prevent serious injuries and fatalities.

Governance Highlights and Investor Engagement

We seek to adopt and implement corporate governance practices that we believe are in the interests of our shareholders and that reflect best practices. Some of our governance practices include the following:

Our relationship with our shareholders and the investment community is of great importance to our company. Aside from our normal corporate communications, we engage with shareholders, the investment community, and interest groups through our participation in various utility and investment conferences, non-deal roadshows, and frequent one-on-one meetings with investors and other members of the investment community. During those meetings, we solicit input on topics such as corporate governance, executive leadership, dividends, disclosure and corporate communications, transparency, and corporate responsibility. Shareholder support is further evidenced by our 2025 say-on-pay advisory vote, which received a 92.7 percent positive vote from our shareholders.

IDACORP, INC. 2026 PROXY STATEMENT iv

Summary of Our Compensation Policies

We seek to establish performance metrics for incentive compensation that reward our executive officers for achieving objectives that align with our customers' and shareholders’ interests, and we use both operational and financial metrics for our incentive compensation. Our long-term incentive metrics are measures of the creation of shareholder value, rewarding earnings, appreciation in stock price and total shareholder return (TSR). Short-term incentive is paid in cash and long-term incentive is paid in IDACORP restricted stock units. Because of the diversity of our performance metrics, our executive officers’ annual compensation can vary considerably depending on our actual performance in any period. For 2025, we used the following metrics:

We have a number of compensation policies and practices that we use to help align the interests of management with our shareholders, including the following:

ü We use a number of financial and operational performance metrics for executive compensation and have a policy that a significant percentage of our executives’ target compensation be at-risk;

ü We have solely independent directors on our compensation and human resources committee;

ü Our compensation and human resources committee retains an independent compensation consultant;

ü We impose minimum stock ownership and retention obligations for executive officers and performance-based restricted stock units (RSUs) are not counted toward the ownership obligations;

ü We have a clawback policy that provides for the recovery of incentive compensation pursuant to U.S. Securities and Exchange Commission (SEC) and New York Stock Exchange (NYSE) requirements;

ü We impose maximum limits on incentive compensation;

ü We do not provide employment agreements;

ü We do not permit hedging or pledging of our stock by executive officers;

ü We provide only limited perquisites;

ü We do not award stock options;

ü We have a low burn rate on equity for incentive awards;

ü We analyze peer groups and market data; and

ü We set our target goal for TSR performance at the 55th percentile of our peer group for long-term incentive.

In 2025, we received 92.7 percent of votes cast in favor of our executive compensation programs. Please see Part 4 – “Executive Compensation” in this proxy statement for a more detailed discussion of our compensation programs, including plan metrics and payouts.

Our Strategy and Corporate Responsibility Initiatives

We are committed to our focus on competitive total returns and generating long-term value for shareholders.

In executing on the objectives above, we seek to balance the interests of shareholders, Idaho Power customers and employees, and other stakeholders.

IDACORP, INC. 2026 PROXY STATEMENT 3

Corporate Responsibility Initiatives

Our corporate governance and nominating committee, with considerable focus from our board of directors, is primarily responsible for the oversight of our corporate responsibility initiatives. These initiatives are identified by management (with input from the company’s various stakeholders) as material to the company's business and the board of directors is informed at least quarterly by management of the status and results of our corporate responsibility efforts. We publicly release annual corporate responsibility reports, which detail our corporate responsibility initiatives. The most current corporate responsibility report is located on Idaho Power’s website, together with other information on corporate responsibility issues relevant to Idaho Power. The corporate responsibility reports and related website content are not incorporated by reference into this proxy statement.

Clean_Today Cleaner Tomorrow_2025_WEB.jpg

Board and Board Committee Oversight of Human Capital Management

Our board of directors provides oversight for the company's human capital management. Management updates the full board of directors and its committees regularly on safety metrics, total rewards for employees, benefit and pension programs, succession planning and training programs, and corporate culture initiatives, among other things. Each committee of the board of directors is delegated and takes on specific roles in this oversight. The compensation and human resources committee is responsible for overseeing employee compensation and benefit plans and general labor issues, as well as corporate culture matters. The audit committee is responsible for overseeing risk management, including compliance with the code of business conduct and physical and cybersecurity risks. The corporate governance and nominating committee is responsible for overseeing risks associated with governance and social issues associated with employees as part of its corporate responsibility risk oversight function.

Safety

In 2025, we also implemented vehicle walk-arounds as a standard practice, resulting in 60% more catches of potentially unsafe conditions; updated our job briefing process to increase consistency and improve collaboration between teams; reduced body-

IDACORP, INC. 2026 PROXY STATEMENT 4

positioning injuries by 15%, demonstrating that our focus on moving safely through ergonomics, coaching, and deliberate task execution is making an impact; found that 98% of employees feel empowered to speak up for safety, according to our employee engagement survey; and held two safety-focused sessions with contractors to help align our expectations and best practices.

Our Culture

One of our core values as a company is “respect for all.” Our Code of Business Conduct, available publicly on our website, states our position that employees deserve a workplace where they are treated in a professional and respectful manner, and each of our employees has the responsibility to create and maintain such an environment. Our talent acquisition and development teams within our Human Resources department partner closely with senior management to ensure alignment of the company's human capital management with our corporate values. We strive to recruit and retain talent from all backgrounds, instill a welcoming culture, and strengthen programs that provide advancement opportunities for all our employees. We have programs in place to educate students on workforce opportunities in the energy industry, training to ensure a respectful workplace, and engagement in community outreach and partnerships. We also have a steering committee consisting of officers, senior managers, and other employees to help the company foster a culture of respect and belonging. Certain of our officers regularly provide information on corporate culture initiatives and other corporate responsibility efforts to our board of directors and board committees.

Employee Satisfaction

Our human capital programs are designed to attract, retain, and develop the highest quality employees. We consistently experience a low voluntary attrition rate of less than 3 percent that we attribute to maintaining a good relationship with our employees due to a strong safety culture, respectful and welcoming environment, opportunities for development, and competitive compensation and benefits. We regularly conduct employee engagement surveys to seek feedback from our employees. We share the survey results with employees, and senior management incorporates the results of the surveys in their action plans in order to respond to the feedback and improve employee relations. We achieved an 88 percent participation rate in the 2025 employee engagement survey with an impressive overall 94 percent positive employee satisfaction score.

Total Rewards

We provide our employees with competitive pay and benefits, based in large part on salary studies and market data. We use a structured compensation schedule and regularly conduct compensation analyses that help mitigate the potential for gender, race, or ethnicity-based disparities in compensation. Beyond base salaries and incentive compensation, benefits for all full-time employees include a 401(k) plan with company matching contributions, healthcare and insurance benefits, health savings and flexible spending accounts, paid time off, family leave, parental leave, employee assistance programs, and tuition assistance. Currently after five years of employment, a full-time employee vests in Idaho Power’s defined benefit pension plan. We also tie annual employee incentive compensation to metrics based on the categories of earnings, power system reliability, and customer satisfaction reflective of broad stakeholder interests and the value of each employee's contribution.

We deliver a variety of training opportunities and provide rotational assignments and continuous learning and development opportunities to our employees. Our talent development programs, overseen by a talent development team in the Human Resources department, are designed to help employees achieve their career goals, build management skills, and lead their organizations.

We also encourage and enable our employees to support many charitable causes. This includes volunteer program engagement promoted by the company or employees. We also have an employee-led organization called the “Employee Community Funds,” which administers charitable contributions from employees; Idaho Power matches a portion of employee donations, which supplements the company’s separate charitable contributions.

Additional Corporate Responsibility Information

To learn more about our corporate responsibility efforts, see our most recent Corporate Responsibility Report on our website at idacorpinc.com/about-us/sustainability/default.aspx. The information in that report is not incorporated by reference into this proxy statement.

Codes of Business Conduct

We have a Code of Business Conduct that applies to all of our officers and employees. We also have a separate Code of Business Conduct and Ethics for directors. These are posted on our website at idacorpinc.com/corporate-governance/governance-

IDACORP, INC. 2026 PROXY STATEMENT 5

documents/default.aspx. We will also post on that website any amendments to, or waivers of, our Codes of Business Conduct, as required by SEC rules or NYSE listing standards.

Insider Trading Policy

We have adopted an insider trading policy and procedures governing the purchase, sale, and/or other dispositions of our securities by directors, officers, employees, and other covered persons, and have implemented processes for the company, that we believe are reasonably designed to promote compliance with insider trading laws, rules and regulations, and NYSE listing standards. We included a copy of the policy as an exhibit to our most recent Annual Report on Form 10-K.

Board Leadership Structure

The board of directors has separated the positions of chair of the board of directors and chief executive officer (CEO) since 1999. Our CEO is responsible for leadership, overall management of our business strategy, and day-to-day operations, while our chair presides over meetings of our board of directors and provides guidance to our CEO regarding policies and procedures approved by our board of directors. Separating these two positions allows our CEO to focus on our day-to-day business and operations, while allowing the chair of the board of directors to lead the board of directors in its fundamental role of providing advice to, and independent oversight of, management. The board of directors recognizes the time, effort, and energy that the CEO is required to devote to his or her position, as well as the increasing commitment required of the chair position, particularly as the board of directors’ oversight responsibilities continue to grow.

While our bylaws and Corporate Governance Guidelines do not mandate that our chair and CEO positions be separate, the board of directors believes for the reasons outlined above that having separate positions and having an independent director serve as chair is the appropriate leadership structure for the company at this time. The board of directors believes that this issue is part of the succession planning process and that it is in the best interests of the company for the board of directors to make a determination as to the advisability of continuing to have separate positions when it appoints a new CEO.

Risk Oversight and Succession Planning

Our management team is responsible for the day-to-day management of risks the company faces. Our executive vice president, chief financial officer, and treasurer, our vice president and general counsel, and our vice president of finance, compliance, and risk, together with our director of audit services, are responsible for overseeing and coordinating risk assessment processes and mitigation efforts on an enterprise-wide basis. These leaders administer processes intended to identify key business risks, assist in appropriately assessing and managing these risks within stated limits, enforce policies and procedures designed to mitigate risk, and report on these items to other members of senior management and the board of directors. These leaders report regularly to the board of directors and appropriate board committees regarding risks the company faces and how the company is managing those risks.

IDACORP, INC. 2026 PROXY STATEMENT 6

While our senior management team is responsible for the day-to-day management of risk, our board of directors is responsible for ensuring that an appropriate culture of risk management exists within our company, for setting the right “tone at the top,” and assisting management in addressing specific risks that our company faces. The board of directors has the responsibility to oversee the risk management processes designed and implemented by management and confirm the processes are adequate and functioning as designed.

While the full board of directors is ultimately responsible for high-level risk oversight at our company, it is assisted by the executive committee, the audit committee, the compensation and human resources committee, and the corporate governance and nominating committee in fulfilling its oversight responsibilities in certain areas of risk. The executive committee assists the board of directors in fulfilling its oversight responsibilities with respect to the company’s risk management processes generally. The audit committee assists the board of directors in fulfilling its oversight responsibilities with respect to major financial risk exposures and our energy risk management practices (including hedging transactions and collateral requirements) and discusses policies with respect to risk assessment and risk management. Representatives from our independent registered public accounting firm attend audit committee meetings, regularly make presentations to the audit committee, comment on management presentations, and engage in private sessions with the audit committee, without members of management present, to raise any concerns they may have with our risk management practices. The audit committee and the executive committee also assist the board of directors in monitoring management’s risk management framework for cybersecurity and physical security on a regular basis. The compensation and human resources committee assists the board of directors in fulfilling its oversight responsibilities with respect to risks arising from our labor and compensation policies and practices. The corporate governance and nominating committee undertakes periodic reviews of processes for management of risks associated with our company’s organizational structure, governing instruments and policies, and corporate responsibility issues. In fulfilling their respective responsibilities, the committees meet regularly with our officers and members of senior management, as well as our internal and external auditors. Each committee has full access to management, as well as the ability to engage and compensate its own independent advisors.

The board of directors receives regular reports from the executive committee, audit committee, compensation and human resources committee, and corporate governance and nominating committee relating to the oversight of risks in their areas of responsibility. Based on this and information provided by management, the board of directors evaluates our risk management processes and oversight and considers whether any changes should be made to those processes or the board of directors’ risk oversight function. We believe that this division of risk oversight ensures that oversight of each type of risk the company faces is allocated, at least initially, to the particular directors most qualified to oversee it. It also promotes board efficiency because the committees are able to select the most timely or important risk-related issues for the full board of directors to consider.

Another area where our board of directors is actively involved is in monitoring our succession planning. The board of directors reviews the succession plans developed by members of senior management at least annually, with a focus on ensuring a talent pipeline at the officer level and for specific critical roles. We seek to ensure that our directors are exposed to a variety of members of our leadership team, and not just the senior-most officers, on a regular basis, through formal presentations and informal events. Our board of directors is also informed of general workforce trends, expected retirement levels or turnover, and recruiting and development programs, which is of particular importance given Idaho Power’s specialized workforce.

Board Meetings and Director Attendance

The members of our board of directors are expected to attend board meetings and the meetings of board committees on which they serve, to spend the time needed and to meet as frequently as necessary to properly discharge their responsibilities. The board of directors held four meetings in 2025. Each director attended at least 75 percent of the aggregate of the meetings held by (i) the board of directors in 2025 (during the period for which he or she was a director) and (ii) the committees on which he or she served in 2025 (during the periods that he or she served). Our Corporate Governance Guidelines provide that all directors are expected to attend our annual meeting of shareholders and be available, when requested by the chair of the board of directors, to answer any questions shareholders may have. All then-serving members of the board of directors attended our 2025 annual meeting of shareholders.

Board Committee Charters

Our standing committees of the board of directors are the executive committee, the audit committee, the compensation and human resources committee, and the corporate governance and nominating committee. We have:

• charters for the audit committee, compensation and human resources committee, and corporate governance and nominating committee; and

IDACORP, INC. 2026 PROXY STATEMENT 7

• Corporate Governance Guidelines, which address issues including the responsibilities, qualifications, and compensation of the board of directors, as well as board leadership, board committees, director resignation, and board self-evaluation.

Our committee charters and our Corporate Governance Guidelines may be accessed on our website at idacorpinc.com/corporate-governance/governance-documents/default.aspx. Information on our committees of the board of directors is included in Part 3 – “Board of Directors – Committees of the Board of Directors.”

Director Independence and Executive Sessions

Our board of directors has adopted a policy, contained in our Corporate Governance Guidelines, that the board of directors will be composed of a majority of independent directors. The board of directors reviews annually the relationships that each director has with the company (either directly or as a partner, shareholder, or officer of an organization that has a relationship with the company). Following the annual review, only those directors who the board of directors affirmatively determines have no material relationship with the company and can exercise independent judgment will be considered independent directors, subject to additional qualifications prescribed under the listing standards of the NYSE and under applicable laws.

All members of our board of directors are non-employees, except Lisa A. Grow, who is our president and CEO. The board of directors has determined that all members of our board of directors, other than Ms. Grow, are independent, based on all relevant facts and circumstances and under the NYSE listing standards and our Corporate Governance Guidelines.

Our directors meet in executive session at each regular meeting of the board of directors. Additionally, our independent directors meet separately in executive session periodically, and not less frequently than annually. The independent chair of the board of directors presides at board meetings and at executive sessions of independent and non-management directors.

Board Membership Criteria

We believe that directors should possess the highest personal and professional ethics, integrity, and values and be committed to representing the long-term interests of our shareholders. Directors must also have an inquisitive and objective perspective, practical wisdom, and mature judgment. We also consider a nexus to Idaho Power’s service area a desirable trait. We endeavor to have a board with a variety of business and personal attributes and experience at policy-making levels in areas that are relevant to our business activities. We believe our director nominees bring a strong mix of attributes and experiences to the board of directors as leaders in business, finance, accounting, regulation, and the utility industry as shown in the chart below.

IDACORP, INC. 2026 PROXY STATEMENT 8

Under the oversight of the corporate governance and nominating committee, the board of directors conducts an annual self-evaluation of its performance and utilizes the results to assess and determine the characteristics and critical skills required of directors. Each of our audit, compensation and human resources, and corporate governance and nominating committees also performs an annual self-assessment. The board of directors and committee self-assessment surveys are completed anonymously by each board member and committee member and provide for a full assessment of board of directors and committee performance, including recommendations for improvement. The board of directors and committees review the compiled results from the respective self-assessment surveys and discuss responsive actions to the survey results. Each board member also completes a questionnaire related to compliance with independence standards and director qualifications annually. The responses are provided to our general counsel and corporate secretary and a report is compiled for the corporate governance and nominating committee. This report is also presented for review by the full board of directors. In addition, our Corporate Governance Guidelines and the corporate governance and nominating committee charter provide that the corporate governance and nominating committee will annually review board committee assignments and consider the rotation of the chair and members of the committees with a view toward balancing the benefits derived from continuity against the benefits derived from the breadth of experience and viewpoints of the various directors. The corporate governance and nominating committee recommendations are then provided to the board of directors for review and approval.

In addition, we require that:

•at least one member of our audit committee be an “audit committee financial expert;”

•the audit, compensation and human resources, and corporate governance and nominating committees are comprised solely of independent directors;

•our directors automatically retire immediately prior to the first annual meeting of shareholders after they reach age 72; and

•a majority of board members be independent under our Corporate Governance Guidelines and applicable NYSE listing standards.

Director Resignation Policy

We have a policy that provides that if any director nominee in an uncontested election receives a greater number of votes “withheld” from his or her election than votes “for” such election, the director nominee must tender his or her resignation to the board of directors promptly after the voting results are certified. The corporate governance and nominating committee, comprised entirely of independent directors and which will specifically exclude any director who is required to tender his or her own resignation, will consider the tendered resignation and make a recommendation to the board of directors, taking into account all factors deemed relevant. These factors include, without limitation, the underlying reasons why shareholders withheld votes from the director (if ascertainable) and whether the underlying reasons are curable, the length of service and qualifications of the director whose resignation has been tendered, the director's contributions to our company, whether by accepting the resignation we will no longer be in compliance with any applicable law, rule, regulation, or governing document, and whether or not accepting the resignation is in the best interests of our company and our shareholders. Our board of directors will act upon the corporate governance and nominating committee’s recommendation within 90 days following certification of the shareholder vote and will consider the factors considered by the corporate governance and nominating committee and any additional information and factors as the board of directors believes to be relevant. We will publicly disclose the board of directors’ decision and rationale with regard to any resignation offered under the director resignation policy.

Process for Determining Director Nominees

In determining the composition of our board of directors, we seek a balanced mix of local experience, which we believe is specifically relevant for a utility, and national or public company experience, among other factors. As a utility company with operations predominantly in Idaho and Oregon, we believe it is important for our company and our local directors to be involved in and otherwise support local community and charitable organizations.

Our corporate governance and nominating committee is responsible for selecting and recommending to the board of directors candidates for election as directors, including Ms. Miller. Our Corporate Governance Guidelines contain procedures for the committee to identify and evaluate new director nominees, including candidates our shareholders recommend in compliance with our Corporate Governance Guidelines. The corporate governance and nominating committee begins the process of identifying and evaluating potential nominees for director positions by taking into consideration the results of the annual director questionnaires and self-evaluation process described above while keeping the full board of directors informed of the nominating process. The corporate governance and nominating committee reviews candidates recommended by shareholders and may hire a search firm to identify other candidates.

IDACORP, INC. 2026 PROXY STATEMENT 9

The corporate governance and nominating committee gathers additional information on the candidates to determine if they qualify to be members of our board of directors. The corporate governance and nominating committee examines whether the candidates are independent, whether their election would violate any federal or state laws, rules, or regulations that apply to us, and whether they meet all requirements under our Corporate Governance Guidelines, committee charters, bylaws, codes of business conduct and ethics, and any other applicable corporate document or policy. The corporate governance and nominating committee also considers whether the nominees will have potential conflicts of interest, and whether they will represent a single or special interest, before finalizing a list of candidates for the full board of directors to consider for nomination.

Process for Shareholders to Recommend Candidates for Director

Our Corporate Governance Guidelines set forth the requirements that you must follow if you wish to recommend director candidates to our corporate governance and nominating committee. If you recommend a candidate for director, you must provide the following information:

• the candidate’s name, age, business address, residence address, telephone number, principal occupation, the class and number of shares of our voting stock the candidate owns beneficially and of record, a statement as to how long the candidate has held such stock, a description of the candidate’s qualifications to be a director, whether the candidate would be an independent director, and any other information you deem relevant with respect to the recommendation; and

• your name and address as they appear on our stock records, the class and number of shares of voting stock you own beneficially and of record, and a statement as to how long you have held the stock.

Recommendations must be sent to our corporate secretary at the address provided below. Our corporate secretary will review all written recommendations and send those conforming to the requirements described above to the corporate governance and nominating committee for review and consideration. The corporate governance and nominating committee evaluates the qualifications of candidates properly submitted by shareholders in the same manner as it evaluates the qualifications of director candidates identified by the committee or the board of directors.

Shareholders who wish to nominate persons for election to the board of directors, rather than recommend candidates for consideration by the corporate governance and nominating committee and board of directors, must follow the procedures set forth in our bylaws, and must comply with the requirements of Rule 14a-19 under the Exchange Act. Copies of our bylaws may be obtained by writing to our corporate secretary at IDACORP, Inc., 1221 West Idaho Street, Boise, Idaho 83702-5627, or by calling our corporate secretary at (208) 388-2200. See also the section entitled 2027 Annual Meeting of Shareholders in Part 6 - “Other Matters” in this proxy statement.

Communications with the Board of Directors and Audit Committee

Shareholders and other interested parties may communicate with members of the board of directors by:

• calling (866) 384-4277 if they have a concern to bring to the attention of the board of directors, our chair of the board of directors, or our non-employee directors as a group; or

• logging on to secure.ethicspoint.com/domain/media/en/gui/62899/index.html and following the instructions to file a report if the concern is of an ethical nature.

Our general counsel receives all such communications. These communications are distributed to the board of directors, or to the chair or specific directors as appropriate, depending on the facts and circumstances of the communication. Communications may include the reporting of concerns related to governance, corporate conduct, business ethics, financial practices, legal issues, and accounting or audit matters. If a report concerns questionable accounting practices, internal accounting controls, or auditing matters, our general counsel will also forward your report to the chair of the audit committee. The acceptance and forwarding of a communication to any director does not imply that the director owes or assumes any fiduciary duty to the person submitting the communication, all such duties being only as prescribed by applicable law.

Political Advocacy and Lobbying Activities

We routinely engage in federal, state, and local public policy discussions ranging from issues that specifically impact the generation, transmission, and distribution of electricity to more general topics related to regulation, taxation, business, and labor. Our political advocacy objectives focus on a variety of interests, including costs to customers and owners, safety, reliability

IDACORP, INC. 2026 PROXY STATEMENT 10

of service, and our responsibility to the environment, employees, stakeholders, and communities. To that end, we are also active in a number of state, regional, and national trade associations that may engage in political activity on these issues.

Our voluntary, non-partisan employee political action committee (IDA-PAC) participates in the political process through contributions to candidate campaigns, other political action committees, and ballot measure campaigns in compliance with applicable laws. Those contributions are made in furtherance of the company’s interests and without regard to the personal political preferences of our directors, executives, or employees. In 2015, the board of directors voluntarily adopted a policy in response to the 2010 U.S. Supreme Court decision in Citizens United v. Federal Election Commission that we will not provide direct corporate funding for independent advertisements that support or oppose political candidates for election to federal public office.

Further, our senior vice president of public affairs who monitors and approves all such activities, is required to report lobbying expenditures; contributions to candidates, ballot measures and initiatives, trade and industry associations, and certain other organizations that may engage in activities involving legislative measures; and electioneering to the corporate governance and nominating committee for their review on an annual basis. The corporate governance and nominating committee reviews our political contributions (including IDA-PAC contributions) and our lobbying efforts and updates the full board of directors on such activities.

Corporate political contributions and lobbying activities are subject to regulation by the states in which we operate and the federal government, including requirements to provide disclosures of federal and state lobbying expenses, which are made publicly available by the various government authorities to which we report. For 2025, we contributed approximately $66,600 to political action committees at all levels of government. Of that amount, $22,500 was contributed by IDA-PAC to federal candidates and political action committees. We also contributed $49,750 to candidates for Idaho state elections and $17,000 to candidates for Oregon state elections. Contributions to candidates were made to both primary political parties. We also spent approximately $1,002,750 on lobbying expenditures, including compensation for our employees engaged in lobbying efforts, contractors, and membership dues for trade associations. We made no contributions to 527 groups, 501(c)(4) organizations associated with public officials, or to ballot measures in 2025.

Anti-Hedging and Anti-Pledging Policy

Our compensation policy and Corporate Governance Guidelines prohibit directors and executive officers from hedging their ownership of company common stock. Under our policy, a director or executive officer may not enter into transactions that allow the director or officer to benefit from devaluation of our stock or be the technical legal owner of our stock without the full benefits and risks of such ownership. In addition, our Corporate Governance Guidelines provide that our directors, officers, and senior managers are prohibited from pledging (through a margin feature or otherwise) our securities as collateral in order to secure personal loans or other obligations. The guidelines and policy do not generally apply to all employees.

Certain Relationships and Related Transactions

Our related person transactions policy defines a “related person transaction” as a transaction between a related person and our company in which the amount exceeds $120,000. The related person transactions policy defines a “related person” as any:

• officer, director, or director nominee of IDACORP or any subsidiary;

• person known to be a greater than 5 percent beneficial owner of IDACORP voting securities;

• immediate family member of the foregoing persons, or person (other than a tenant or employee) sharing the household of the foregoing persons; or

• firm, corporation, or other entity in which any person named above is a partner, principal, executive officer, or greater than 5 percent beneficial owner, or where such person otherwise has a direct or indirect material interest.

IDACORP, INC. 2026 PROXY STATEMENT 11

The following types of transactions are excluded from the related person transactions policy:

• transactions available to all employees generally;

• the purchase or sale of electric energy at rates fixed in conformity with law or governmental authority;

• transactions involving compensation, employment agreements, or special supplemental benefits for directors or officers that are reviewed and approved by the compensation and human resources committee;

• transactions between or among companies within the IDACORP family; and

• transactions where the rates or charges involved in the transaction are determined by competitive bids, or the transaction involves the rendering of services as a common or contract carrier, or public utility, at rates or charges fixed in conformity with law or governmental authority.

The corporate governance and nominating committee administers the policy, which includes procedures to review related person transactions, approve or disapprove related person transactions, and ratify unapproved transactions. The policy, which is in writing, also specifically requires prior corporate governance and nominating committee approval of proposed charitable contributions or pledges of charitable contributions in excess of $120,000 in any calendar year to a charitable or not-for-profit organization identified as a related person, except those nondiscretionary contributions made pursuant to our matching contribution program. The board of directors may approve a proposed related person transaction after reviewing the information considered by the corporate governance and nominating committee and any additional information it deems necessary or desirable:

• if it determines in good faith that the transaction is in, or is not inconsistent with, the best interests of our company and the shareholders; and

• if the transaction is on terms comparable to those that could be obtained in an arm’s-length dealing with an unrelated third party.

Jeffrey L. Malmen, our senior vice president of public affairs, is married to Erika Eaton Malmen, who is a partner at the law firm of Perkins Coie LLP, and Idaho Power has engaged Perkins Coie LLP for legal services for over 40 years. Mr. Malmen is one of Idaho Power’s “named executive officers” for 2025, and thus his compensation for 2025 is described in Part 4 – “Executive Compensation” in this proxy statement. Idaho Power’s relationship with Perkins Coie LLP began prior to Mr. Malmen’s employment with the companies and Ms. Malmen’s partnership at the law firm. In 2025, Perkins Coie LLP was paid approximately $1.0 million for legal services provided to IDACORP and Idaho Power. This work was performed under the supervision of Idaho Power’s general counsel and the contractual and fee arrangements were comparable to other national law firms providing legal services to Idaho Power. Ms. Malmen is among the lawyers at Perkins Coie LLP who provided legal services to us in 2025. Mr. Malmen does not participate in decisions with respect to whether we hire Perkins Coie LLP as outside counsel. In 2025, the corporate governance and nominating committee and the board of directors reviewed, ratified, and approved the potential related party transaction involving Perkins Coie LLP.

The following officers are related to or have a relationship with Idaho Power employees as described below:

•Lisa A. Grow's (our president and CEO) son-in-law, Connor Saxe;

•Bo Hanchey's (our vice president of customer operations and chief safety officer) sister, Daisi Pohanka, and shared household with Ashley Herrera; and

•Amy I. Shaw's (our vice president of finance, compliance, and risk) spouse, Eric Shaw.

Each of Connor Saxe, Daisi Pohanka, Ashley Herrera, and Eric Shaw is an Idaho Power employee who received a combined base salary and incentive compensation from Idaho Power in excess of $120,000 in 2025. None of these individuals is an officer of Idaho Power and her or his base salary and incentive compensation were consistent with amounts paid to Idaho Power employees in similar roles. The compensation and human resources committee and full board of directors also approved the design and metrics of the incentive programs in which these individuals participated in 2025. In 2026, the corporate governance and nomination committee and the board of directors reviewed, ratified, and approved the potential related party transactions involving each of Connor Saxe, Daisi Pohanka, Ashley Herrera, and Eric Shaw.

IDACORP, INC. 2026 PROXY STATEMENT 14


PART 3 – BOARD OF DIRECTORS

PROPOSAL NO. 1: Election of Directors

Our first proposal pertains to the election of our directors. After the Annual Meeting and upon election of the proposed director nominees, the board of directors will consist of ten members. Upon the recommendation of our corporate governance and nominating committee, our board of directors has nominated the ten individuals listed below to serve as directors. Each of the ten nominees served as a member of our board of directors during 2025, except for Ms. Miller. The nominees consist of nine independent directors, as defined by the rules of the NYSE, and Lisa A. Grow, our current president and CEO.

Each director’s term runs from the date of his or her election until our next annual meeting of shareholders or until his or her successor (if any) is elected or appointed. While we expect that all of the nominees will be able to qualify for and accept office, if for any reason one or more should be unable or unwilling to do so, the individuals named as proxies may vote for a substitute nominee chosen by the present board of directors to fill the vacancy. Alternatively, the board of directors could decide to reduce the size of the board, or the proxies could be voted for the remaining nominees, leaving a vacancy on the board.

Under the resignation policy adopted by the board of directors and included in our Corporate Governance Guidelines, if a director nominee in an uncontested election receives a greater number of votes “withheld” from his or her election than votes “for” such election, the director must promptly tender his or her resignation to the board of directors. The board of directors will then decide whether to accept the tendered resignation within 90 days following certification of the shareholder vote (based on the recommendation of the corporate governance and nominating committee, which is comprised exclusively of independent directors). In accordance with our policy, we will publicly disclose the board of directors’ decision and its reasoning with regard to the offered resignation.

There are no family relationships among any director, director nominee, or executive officer.

The composition of our board of directors is identical to the composition of Idaho Power’s board of directors.

Audit Committee

The audit committee is a separately designated standing committee. The audit committee has numerous responsibilities, including:

•assists the board of directors in the oversight of the integrity of our financial statements; compliance with legal and regulatory requirements; the qualifications, independence, and performance of our independent registered public accounting firm and the performance of our internal audit department; and our major financial, regulatory, and physical and cybersecurity risk exposures, including oversight of management’s information security activities, which include briefing the audit committee and the board on information security matters several times a year, conducting an annual security training program, and arranging for external security assessments;

•discusses with our independent registered public accounting firm and our internal auditors the audit of, and opinion on, the company’s financial statements and our internal control over financial reporting, including the overall scope and plans for audits, critical audit matters, and any other matters deemed appropriate;

•is directly responsible for the appointment, compensation, retention, and oversight of the work of our independent registered public accounting firm, helping to ensure that the selection of the firm and its lead audit partner is in the best interests of the company and our shareholders;

•prepares the audit committee report required to be included in the proxy statement for our annual meeting of shareholders; and

•other responsibilities of the audit committee specified in its charter, available at idacorpinc.com/corporate-governance/governance-documents/default.aspx.

All members of the audit committee are independent under our Corporate Governance Guidelines and applicable NYSE listing standards, including the SEC’s audit committee member independence standards. The board of directors has determined that Ms. Elg, Mr. Kennedy, and Mr. Madison are “audit committee financial experts” as defined by the rules of the SEC. During 2025, the audit committee met eight times.

IDACORP, INC. 2026 PROXY STATEMENT 21

Compensation and Human Resources Committee

The compensation and human resources committee has direct responsibility to:

•review and approve corporate goals and objectives relevant to our CEO’s compensation;

•evaluate our CEO’s performance in light of those goals and objectives;

•as a committee and together with the other independent directors and with guidance from Pay Governance, determine and approve our CEO’s compensation based on this evaluation;

•make recommendations to the board of directors with respect to non-CEO executive officer compensation, incentive compensation plans, and equity-based plans that are subject to board of director approval;

•review and discuss with management the compensation discussion and analysis, and based on such review and discussion determine whether to recommend to the board of directors that the compensation discussion and analysis be included in our proxy statement for the annual meeting of shareholders;

•oversee our compensation and employee benefit plans and practices;

•oversee our practices that pertain to human capital management;

•assist the board of directors in the oversight of risks arising from our compensation and human resources policies and practices; and

•other responsibilities of the compensation and human resources committee specified in its charter, available at idacorpinc.com/corporate-governance/governance-documents/default.aspx.

The compensation and human resources committee and the board of directors have sole responsibility to determine executive officer compensation, which responsibility may not be delegated. The compensation and human resources committee has sole authority to retain and terminate any consulting firm to assist the compensation and human resources committee in carrying out its responsibilities, including sole authority to approve the consulting firm’s fees and other retention terms. In 2025, the compensation and human resources committee retained Pay Governance for advice regarding executive officer compensation, primarily to provide the compensation and human resources committee with general compensation market information and trends, to review the structure of our compensation programs, and to provide insight and analysis to the compensation and human resources committee at committee meetings. Management and the compensation and human resources committee also reviewed data provided by Pay Governance in evaluating our compensation and benefit plans.

In retaining compensation consultants, the compensation and human resources committee’s charter provides that the committee is required to consider factors bearing on the independence from management of the compensation consultant and whether the work performed by the compensation consultant will raise any conflicts of interest. Although management may request services, the compensation and human resources committee must pre-approve the engagement of the consulting firm for any services to be provided to management. These services may not interfere with the consulting firm’s advice to the compensation and human resources committee. The chair may pre-approve services between regularly scheduled meetings of the compensation and human resources committee. Pre-approval of services by the chair must be reported to the compensation and human resources committee at its next meeting.

In addition, the compensation and human resources committee has responsibility for reviewing and making recommendations with respect to director compensation to the board of directors. For information on director compensation, refer to the section entitled “Director Compensation” in this proxy statement.

Each member of the compensation and human resources committee is independent under our Corporate Governance Guidelines and applicable NYSE listing standards. During 2025, the compensation and human resources committee met five times.

Compensation and Human Resources Committee Interlocks and Insider Participation

No person who served as a member of the compensation and human resources committee during 2025 (a) has served as one of our officers or employees or (b) has any relationship requiring disclosure under Item 404 of the SEC’s Regulation S-K. None of our executive officers serves as a member of the board of directors or compensation and human resources committee of any other company that has an executive officer serving as a member of our board of directors or our compensation and human resources committee.

Corporate Governance and Nominating Committee

The corporate governance and nominating committee’s responsibilities include:

• identifying individuals qualified to become directors, consistent with criteria approved by the board of directors;

IDACORP, INC. 2026 PROXY STATEMENT 22

• selecting, or recommending that the board of directors select, the candidates for all directorships to be filled by the board of directors or by the shareholders;

• developing and recommending to the board of directors our Corporate Governance Guidelines;

• overseeing the evaluation of the board of directors and management;

• overseeing the company's practices as they pertain to corporate responsibility risk oversight;

•taking a leadership role in shaping our corporate governance; and

•other responsibilities of the corporate governance and nominating committee specified in its charter, available at idacorpinc.com/corporate-governance/governance-documents/default.aspx.

Each member of the corporate governance and nominating committee is independent under our Corporate Governance Guidelines and the applicable NYSE listing standards. During 2025, the corporate governance and nominating committee met four times.

Executive Committee

The executive committee acts on behalf of the board of directors when the board of directors is not in session, except on those matters that require action of the full board of directors. The executive committee also assists the board of directors in overseeing risk management and providing approval of financing transactions. The executive committee is composed of our CEO and the chair of each of our other standing committees. During 2025, the executive committee met two times.

Director Compensation

We structure director compensation to attract and retain qualified non-employee directors and to further align the interests of our directors with the interests of our shareholders. The compensation and human resources committee periodically reviews surveys of non-employee director compensation trends and a competitive analysis of peer company practices prepared by the independent compensation consultant (Pay Governance) and our Human Resources team. The compensation and human resources committee then makes recommendations to the board of directors on compensation for our non-employee directors, including their board and committee retainers and annual equity awards. There were no changes to director compensation for 2025 as compared to 2024.

The table that follows describes the compensation earned during 2025 by each individual who served as a director during 2025.

1 Directors are paid cash fees on a monthly basis during their service on the board of directors. Ms. Elg was paid $8,000 in excess of the amounts due during 2025 due to clerical error. That amount is not included in this column and will be deducted from 2026 fees.

2 This column reflects the grant date fair value of IDACORP common stock awarded to our non-employee directors measured in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 718 – Stock Compensation (FASB ASC Topic 718). The grant date fair value is based on the closing price of IDACORP common stock on the business day before the grant date. The grant date fair value for the awards included in this column for all non-employee directors except Mr. Kennedy is based on the closing price of IDACORP common stock on February 28, 2025, which was $117.91. The award for Mr. Kennedy is based on the closing price of IDACORP common stock on May 30, 2025, which was $118.95.

IDACORP, INC. 2026 PROXY STATEMENT 23

3 Employee directors do not receive fees or awards for service as a member of our board of directors. Ms. Grow's compensation as an executive officer is discussed in Part 4 – “Executive Compensation” in this proxy statement.

4 Mr. Jibson and Mr. Navarro concluded their respective service as directors on May 15, 2025, and Ms. Johansen concluded her service as director on December 31, 2025. Mr. Madison and Mr. Kennedy began their service as directors in February and May 2025, respectively.

The table that follows lists the forms and amounts of compensation payable to our non-employee directors for 2025. All directors of IDACORP also serve as directors of Idaho Power. The fees and other compensation shown in the table and discussed below are for service on both boards as well as for service on any subsidiary board. Employee directors receive no compensation for service on the boards.


Annual Director Compensation Amounts for 2025
Base Retainer			$100,000
Base Committee Annual Retainers:
Audit committee			$12,000
Compensation and human resources committee			$8,500
Corporate governance and nominating committee			$7,500
Executive committee			$3,000
Additional Chair Annual Retainers:
Chair of the board			$100,000
Chair of audit committee			$15,000
Chair of compensation and human resources committee			$15,000
Chair of corporate governance and nominating committee			$12,500
Annual Stock Awards			$140,000

Deferral Arrangements

Directors may defer all or a portion of their annual IDACORP and Idaho Power cash retainers and receive payment of all amounts deferred with interest in a lump sum or in a series of up to ten equal annual payments after they separate from service with IDACORP and Idaho Power. All cash fees that were deferred for service as a member of the board of directors in 2025 were credited with interest using the average rate published as part of “Moody’s Bond Indices for Utility Avg.” for utilities by Moody's Analytics (the “Moody’s Rate”). Interest is calculated on a pro-rated basis each month using a 360-day year and the average Moody’s Rate for the preceding month.

Directors may also defer their annual stock awards, which are then held as deferred stock units with dividend equivalents reinvested in additional deferred stock units. Upon separation from service with IDACORP and Idaho Power, directors will receive either a lump-sum distribution or a series of up to ten equal annual installments. Upon a change in control, the directors’ deferral accounts will be distributed to each participating director in a lump sum. The distributions will be in shares of our common stock, with each deferred stock unit equal to one share of our common stock and any fractional shares paid in cash.

Stock Ownership Guidelines for Directors

Our stock ownership guidelines for non-employee directors require that each non-employee director own IDACORP common stock equal in value to five times his or her current base annual retainer fee (e.g. $100,000 x 5 = $500,000). A director is allowed five years from the date of the director’s initial appointment or election to meet these requirements. As of December 31, 2025, all of our directors were in compliance with the guidelines. Once a director reaches the stock ownership target under the guidelines, based on the then-current stock price, the director will remain in compliance with the guidelines, despite future changes in stock price, as long as the director continues to own the minimum number of shares that brought the director into compliance with the stock ownership target. If the base annual retainer fee for directors increases, directors who have already met their stock ownership targets will need to meet the stock ownership guidelines only for the amount of increase in the base annual retainer fee.

Anti-Hedging and Anti-Pledging Policy for Directors

The same prohibitions on hedging ownership of our common stock and the pledging of our securities as collateral that apply to our executive officers, which are described in Part 4 – “Executive Compensation – Compensation Discussion and Analysis – Other Compensation Practices” of this proxy statement, apply equally to members of our board of directors.

IDACORP, INC. 2026 PROXY STATEMENT 24


PART 4 - EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

This Compensation Discussion and Analysis (CD&A) contains statements regarding future performance targets and goals. These targets and goals are disclosed in the limited context of our compensation programs and should not be understood to be statements of management’s expectations or estimates of results or other guidance. We caution readers not to apply these statements to other contexts.

Executive Summary

This part of the proxy statement focuses on our 2025 performance, our strategy, our shareholder engagement process, and the compensation we provide to our NEOs, including our 2025 executive compensation programs and decisions. For 2025, our NEOs were as follows (with their current titles as of the date of this proxy statement):


•Lisa A. Grow			President and CEO of IDACORP and Idaho Power
•Brian R. Buckham			Executive vice president, chief financial officer, and treasurer of IDACORP and Idaho Power
•Adam J. Richins			Executive vice president and chief operating officer of Idaho Power
•Jeffrey L. Malmen			Senior vice president of public affairs of IDACORP and Idaho Power
•Timothy E. Tatum			Vice president of regulatory affairs of Idaho Power

IDACORP and Idaho Power had another successful year in 2025. IDACORP achieved its 18th consecutive year of earnings per share growth and increased its quarterly dividend, while Idaho Power continued to provide reliable, affordable electric service to its customers amid approximately 2.3% annual growth in retail customers and $1.1 billion in cash capital expenditures, excluding allowance for funds used during construction and net costs of removing assets from service, to address rapidly increasing load growth in a safe, cost-effective manner.

Compensation Policy Summary

We aim to attract and retain the highest caliber of executive management who can operate in the specialized electric utility field and balance the interests of our owners, customers, regulators, and other stakeholders. Each year, the compensation and human resources committee carefully evaluates the incentive plan structure, metrics, and performance goals for our short-term and long-term incentive plans.

For 2025, the compensation and human resources committee determined, following discussion with its compensation consultant and management, that the existing plan design for our short-term incentive and long-term incentive programs remained well-balanced and effective in incentivizing operational and financial performance. As a result, the structure of our short-term and long-term incentive programs for 2025 was relatively unchanged from the prior year, except that the financial goals under our short-term incentive plan were reduced to a single goal related to adjusted net income.

Our short-term incentive plan encompasses three goals: one financial goal (70 percent weighting) and two operational goals (combined 30 percent weighting). Our short-term incentive financial goal for 2025 was based on net income attributable to IDACORP, adjusted for material, non-recurring extraordinary events (such as impairment charges, changes in accounting principles, financial impacts of acquisition, divestiture, and restructuring activities, enactment of new federal or state laws, etc.), as described below in “Short-Term Incentive Compensation – Financial Performance Goal.” We seek to set our target adjusted net income goal at a level that will provide a “stretch goal” for management and encourage positive results for adjusted net

IDACORP, INC. 2026 PROXY STATEMENT 25

income. This aligns with our overall objective of setting new goals each year that will be realistic enough to be achievable yet difficult enough to incentivize a commitment to outstanding performance by management.

We had two short-term incentive operational goals for 2025 related to customer satisfaction and service reliability, respectively. For the customer satisfaction goal, the compensation and human resources committee focused on maintaining rigorous and realistic achievement levels in light of the company’s transition in 2025 to include web-based customer survey results, which generally are lower than telephone-only survey results, in the customer service metric. For the service reliability goal, the committee sought to incentivize continued outstanding service reliability while maintaining a goal realistic enough to be achievable.

Our long-term incentive goals are based on cumulative earnings per share (CEPS) and TSR, with TSR being a relative goal based on our percentile ranking within our TSR comparison group, the EEI Utilities Index. We have consistently set our long-term incentive target goals at or above prior year target goals, which has been effective in producing significant performance increases over time.

At-Risk Compensation

We seek to incentivize strong performance by making a majority of our NEO’s pay “at-risk,” meaning we tie a majority of our NEOs’ compensation to our financial and operational performance. In 2025, approximately 51 percent to 80 percent of our NEOs’ total target direct compensation was at-risk, depending on the role. In order for this at-risk compensation to be earned, our company must achieve strong performance results over one- and three-year performance periods. We believe that this structure provides the appropriate balance between at-risk compensation tied to executive and corporate performance and base salary to promote executive retention. We also apply a policy that the more senior the executive officer's position, the greater the emphasis on long-term results and, therefore, on equity-based compensation. Accordingly, our CEO's compensation is typically weighted more heavily toward long-term incentive compensation in the form of equity. In “Elements and Design Considerations of Compensation for 2025” below, we have included tables to help illustrate the degree to which our NEOs’ compensation is performance-based and thus at-risk.

2025 Compensation

Base Salaries. Based on our continued strong financial and operational results, an analysis of market median compensation of our peers and performance in their respective positions, and the company’s intention to promote executive retention, our NEOs in 2025 received increases in base salaries ranging between 4.1 percent and 8.1 percent compared to their salaries as of year-end 2024.

Incentive Compensation. For 2025, the award opportunities as a percentage of base salary under our short-term incentive plan for Mr. Buckham and Mr. Richins increased from 60 percent to 65 percent and remained unchanged for our other NEOs. The 2025 combined performance results for the three annual performance goals under our short-term incentive plan resulted in a payout of approximately 170 percent of target, reflective of record adjusted net income and strong service reliability performance. The performance-based restricted stock units granted in February 2023 under the long-term incentive plan for the 2023-2025 performance period were earned at an overall 163 percent of target, based on strong cumulative earnings per share from three years of record earnings along with our relative TSR above target at the 64th percentile.

For the awards granted in 2025 under our long-term incentive plan, the award opportunities as a percentage of base salary remained unchanged for our NEOs as compared to 2024. The compensation and human resources committee increased the CEPS goals at all levels of achievement and maintained the relative TSR goals at 2024 levels.

2025 Performance Highlights

In 2025, we provided outstanding service reliability for our customers and made substantial progress on many of our long-term projects and strategic plans, while achieving solid financial performance. The following are some of our specific accomplishments and highlights for the year:

•IDACORP achieved net income growth for an eighteenth consecutive year.

•IDACORP increased its quarterly common stock dividend to $0.88 per share from $0.86 per share, as a part of a 193 percent increase in quarterly dividends approved over the last 14 years.

•Idaho Power's customer count grew 2.3 percent in 2025, and Idaho Power's MWh sales to retail customers in 2025 were the highest in its history, surpassing the previous record set in 2024, reflecting continued growth in its service area.

•In 2025, Idaho Power’s reliability metrics continued to be among the best in company history, as Idaho Power provided uninterrupted service to its retail customers 99.97 percent of the time.

Our Business and Strategic Objectives

We strive to deliver competitive returns and long-term shareowner value through capital appreciation and cash dividends. We focus on targeted capital allocation, growing revenue, a constructive regulatory strategy, and prudent cost management. We embrace innovation to achieve excellent results, and we communicate our plans with integrity and transparency to instill investor confidence. We believe this focus leads to financial strength and quality credit ratings, helping us to reliably and successfully serve our customers and communities, fairly reward employees, meet the expectations of our regulators, and deliver competitive returns to our owners. Our board of directors regularly reviews our long-term strategy, which as of the date of this proxy statement, is focused on the following areas and priorities:

IDACORP, INC. 2026 PROXY STATEMENT 27

Shareholder Engagement and Say-on-Pay Results

We are committed to engaging with our shareholders and soliciting their perspectives on key performance, compensation, and governance issues. The compensation and human resources committee and management are focused on ensuring the appropriate alignment between our programs and our shareholders' preferences. Aside from our normal corporate communications, we engage with shareholders, the investment community, and interest groups through our participation in various utility and investment conferences, non-deal roadshows, and frequent one-on-one meetings with investors and other members of the investment community. During those meetings, we solicit input on topics such as corporate governance, executive leadership, dividends, disclosure and corporate communications, transparency, and corporate responsibility. Shareholder support is evidenced by our 2025 say-on-pay advisory vote, which received a 92.7 percent positive vote from our shareholders.

How We Make Compensation Decisions

Our Compensation Philosophy and Policy

Compensation decisions for our executive officers, including our NEOs, are made in the context of our overall compensation philosophy. Our executive compensation philosophy is to provide balanced and competitive compensation to our executive officers to ensure that we can attract and retain high-quality executive officers, and to motivate our executive officers to achieve performance goals that will benefit our shareholders and customers and contribute to the long-term success and stability of our business without excessive risk-taking. Our board of directors has adopted a written executive compensation policy, and the compensation and human resources committee reviews the policy annually. The policy includes the following compensation-related objectives:

•Manage officer compensation as an investment with the expectation that officers will contribute to our overall success;

•Recognize officers for their demonstrated ability to perform with increasing responsibilities due to system growth and create long-term shareholder value;

•Be competitive with respect to those companies in the markets in which we compete to attract and retain the qualified executives necessary for long-term success;

•Be fair from an internal pay equity perspective;

•Ensure effective utilization and development of talent by working in concert with other management processes, such as performance appraisal, management succession planning, and management development; and

•Balance total compensation with our ability to pay.

Market Compensation Data and Analysis

We believe that market compensation information is important because it provides an indication of the levels of compensation that enable us to remain competitive with other companies in attracting and retaining executive officers. In determining the composition of our peer groups, we consider the following factors:

IDACORP, INC. 2026 PROXY STATEMENT 29

•Breadth - include companies that are philosophically relevant;

•Nature and complexity of the business - take into account each company’s portfolio and markets and seek companies that derive a significant portion of revenues from regulated operations;

•Scope - reflect an appropriate range of revenues and market capitalization;

•Ease of administration - ensure availability of valid and reliable data (e.g., SEC filings); and

•Size - include a sufficient number of companies to provide robust data and mitigate volatility.

We use the market compensation analysis to determine a market compensation range for each of our executive officers for base salary, short-term incentive compensation, and long-term incentive compensation, and for combinations of these three elements, based on compensation provided to officers in similar positions at our designated groups of companies. For setting 2025 compensation, as in prior years, the compensation and human resources committee reviewed survey data for three separate sets of companies, described below, for each executive officer (where data was available). It then assessed each element of compensation, and the total target direct compensation, for each of our executive officers compared to the targeted range (85 percent to 115 percent) of the market median.

The two sources of market compensation data used to prepare the market compensation analysis for our 2025 executive officer compensation were:

1.Public Data Source. 2024 public proxy statement compensation data from a designated peer group of companies, listed below (Peer Group).

Our management, the compensation and human resources committee, and the committee's compensation consultant worked together to develop the Peer Group, which was then approved by the committee. The companies in the Peer Group used for our survey and public proxy data for purposes of establishing 2025 compensation remained unchanged as compared to 2024 and consisted of the following:


ALLETE, Inc.	Hawaiian Electric Industries, Inc.	Pinnacle West Capital Corp.
Alliant Energy Corporation	NorthWestern Energy Group, Inc.	Portland General Electric Co.
Atmos Energy Corporation	Northwest Natural Holding Co.	Spire Inc.
Avista Corp.	OGE Energy Corp.	TXNM Energy, Inc.
Black Hills Corporation	ONE Gas, Inc.

2.Private Survey Data Sources: Willis Towers Watson’s 2024 annual private survey of corporate executive compensation, with the following three subsets of companies:


Peer Group			Comprised of comparable utilities, as determined by the compensation and human resources committee; these are the same companies we use for the public survey data source, listed above
IOU Survey Data			Comprised of all participating investor-owned utilities, regressed to $2.3 billion in annual revenues
General Industry Survey Data			Comprised of all participating general industry companies in “The General Industry Executive Compensation Survey Report - U.S.,” regressed to $2.3 billion in annual revenues

Our annual revenues were approximately $1.8 billion in 2025. We used the $2.3 billion annual revenue figure for our market compensation comparisons to provide a reasonably comparable revenue scope to the broader industry. The $2.3 billion annual revenue figure is intended to reflect what Idaho Power’s annual revenues would be if Idaho Power charged average customer electricity rates. In May 2024, our analysis showed that average U.S. retail electricity rates over the 2021-2023 period were 43 percent higher than Idaho Power’s average retail electricity rates over the same period. We added the same 43 percent differential to our average annual revenues over the 2021-2023 period to establish comparable Idaho Power revenues at approximately $2.3 billion. To determine average U.S. electricity rates, we used the “EEI Typical Bills and Average Rates Report - Select American Cities.”

The committee’s primary market reference for executive compensation was the Peer Group set forth above comprised of comparable utilities to the company in terms of industry, operational complexity, and business profile. This Peer Group was approved by the committee and was also the basis for the company’s primary private compensation survey data.

IDACORP, INC. 2026 PROXY STATEMENT 30

The committee placed primary reliance on this Peer Group because the associated survey data provided broader participation, more detailed role specific information, and greater consistency across pay elements than publicly disclosed proxy data alone.

In addition to the Peer Group, the committee reviewed compensation survey data from a broader group of participating investor owned utilities. This IOU survey group was used as an additional market reference point and was statistically regressed to approximately $2.3 billion in annual revenues to better align with the company’s size. This data provided general context regarding compensation practices across the investor owned utility industry but was not used as the primary basis alone for setting executive compensation.

The committee also reviewed the general industry survey data and publicly available executive compensation information disclosed in 2024 proxy statements filed by companies in the designated peer group. Because this information is less specific and detailed than the Peer Group survey and the IOU survey data, this information was used as a secondary data source to provide general confirmation that compensation levels for the NEOs were within a reasonable range of market practices. General industry survey data and public proxy data was not used in isolation and did not replace the committee’s primary reliance on peer group survey data and informed judgment.

An individual executive officer’s compensation may be positioned above or below the targeted range (85 percent to 115 percent) of the market median for his or her position, depending on his or her level of experience, responsibility, and performance, and based on the degree of comparability between our executive officer’s role and the roles of persons with similar positions at the peer companies, along with internal equity and succession planning considerations. The compensation and human resources committee uses its experience and judgment and our CEO’s feedback on executive officer performance in assessing these factors in determining how an executive officer's compensation should align relative to the market level.

Review of Total Compensation Structure and Internal Pay Ratios

Each year, the compensation and human resources committee reviews the total compensation structure for each NEO, including the elements and mix of compensation, levels of historic compensation, potential termination and retirement benefits, internal equity, and IDACORP stock ownership, to determine whether it should adjust an executive officer’s total target direct compensation. Based on these reviews, the compensation and human resources committee made no changes to the general structure of our compensation programs or to the forms of compensation payable to our executive officers for 2025, though it did make some adjustments to individual compensation amounts, as described in this CD&A. In making this determination, the compensation and human resources committee relied on its experience and judgment.

Individual Executive Officer Performance Goals and Evaluation

An important aspect of the compensation and human resources committee’s process is its review of each executive officer's level of experience and time in the role, responsibility, and individual performance to determine the appropriate market positioning of the executive officer's base salary and target incentive compensation.

For 2025 compensation determinations, the evaluation of Ms. Grow covered strategic capability (vision, strategy, and implementation) and performance in various categories (financial, relationships, leadership, operational, succession planning, and internal controls/ethical compliance).

For purposes of establishing 2025 compensation, the evaluation of all our NEOs covered their performance in financial results, customer satisfaction, operations, and safety, as well as a number of competencies, such as courage, driving innovation, energizing the organization, establishing strategic direction, executive presence, and safety leadership. Each executive officer must also accomplish specific performance goals for each year, which the compensation and human resources committee reviews and evaluates in connection with its compensation decisions. In connection with the review of Ms. Grow's performance, the compensation and human resources committee received input from the other independent directors and guidance from its consultant, Pay Governance.

The compensation and human resources committee also evaluates the NEOs on several factors related to corporate responsibility. Social factors include our ongoing focus on safety, employee engagement, and fostering a culture where all employees feel they belong and are valued for their unique contributions and perspectives. Environmental factors include ongoing environmental stewardship at our hydroelectric facilities and pursuing our carbon emissions reduction goals. The compensation and human resources committee regularly reviews the progress of our NEOs on those objectives, and the results they have generated, including through performance reviews completed by the NEOs.

2025 Named Executive Officer Compensation

Elements and Design Considerations of Compensation for 2025

Our executive compensation for 2025 included the following elements:

•Base salary;

•Annual cash incentive awards;

•Long-term (three year) equity incentive awards; and

•Other benefits, such as health and welfare, retirement and 401(k) plans, and limited perquisites.

The overall design of our 2025 executive compensation program remained largely unchanged from 2024. Members of our management team and our compensation and human resources committee continued to engage with our shareholders in 2025 to ensure our compensation plans, targets, and structure are well communicated, appropriate, and reflect shareholder feedback. Our 2025 executive compensation program provided for fixed compensation (base salary) to provide competitive income, and at-risk compensation (short- and long-term incentive compensation) to help ensure our management team’s focus on our operational and financial performance. Our short-term incentive compensation is paid in cash, if earned, based on single-year performance. Our long-term incentive compensation is paid in IDACORP common stock, if earned, based on performance over a three-year period. The allocation of the total target direct compensation mix for each of our NEOs for 2025, effective as of January 1, 2025, is illustrated in the table that follows and reflects that the at-risk component ranges between approximately 51 percent and 80 percent of each NEO's total target direct compensation.

In connection with its annual review of executive compensation, our compensation and human resources committee reviews the correlation between our executives’ historical compensation and our historical performance. Please see Part 4 – “Executive Compensation – Pay Versus Performance” in this proxy statement for a more detailed discussion of the relationship between our executive compensation and our financial performance.

Base Salary

Base salary consists of fixed cash payments. We pay base salaries in order to provide our executive officers with competitive regular pay that is sufficient to secure officers with the knowledge, skills, and abilities necessary to successfully execute their job duties and responsibilities. Base salary is established based on factors such as competitiveness of the salary compared to similar positions at the company’s peers, the officer's specific responsibilities and experience, and individual and company performance.

For purposes of determining each NEO’s base salary for 2025, the compensation and human resources committee reviewed the base salary market data from the market compensation analysis. This included a comparison of each NEO's current base salary with the median from each of the three data sets for that position (where data was available). As a component of determining appropriate 2025 base salaries (as well as other elements of compensation), the compensation and human resources committee also reviewed the 2024 performance evaluations for each NEO, internal pay equity among the NEOs, and the company’s overall performance during 2024. Based on its review and analysis of this information, in February 2025 the compensation and human

IDACORP, INC. 2026 PROXY STATEMENT 32

resources committee recommended, and the board of directors approved, the NEO base salaries for 2025, effective January 1, 2025, shown in the table that follows:


Executive	2025 Base Salary	% Increase from 2024 Base Salary1
Lisa A. Grow	$1,050,000	5.0%
Brian R. Buckham	$600,000	5.6%
Adam J. Richins	$620,000	6.0%
Jeffrey L. Malmen	$453,000	4.1%
Timothy E. Tatum	$360,000	8.1%

1 Represents the increase relative to the amount of annual base salary in effect as of year-end 2024.

The base salary increases for 2025 for the NEOs reflected, in large part, strong individual and company performance in 2024, competitive market rates, and retention considerations.

Short-Term Incentive Compensation

Short-term incentive compensation under our Executive Incentive Plan is determined by performance relative to annual performance goals and is intended to encourage and reward annual financial and operational results. We provide participants in the Executive Incentive Plan the opportunity to earn cash-based short-term incentives in order to be competitive from a total compensation standpoint and to ensure focus on annual financial, operational, and customer service goals.

The compensation and human resources committee regularly assesses the best metrics to be used in the incentive programs. For 2025, the compensation and human resources committee maintained two of the four metrics from 2024, revised one metric, and discontinued one metric. Preservation of accumulated deferred investment tax credits, or ADITCs, was not continued as a metric for 2025 because it was not expected to be a meaningful goal under the financial performance scenarios considered at the time the goals were adopted. The committee revised the net income metric for 2025 to an adjusted net income metric (as described below) to allow for the exclusion of the impact of certain non-recurring, extraordinary, or unusual events not indicative of our operating performance and align the metric more closely with the results of our ongoing operations.

The committee adopted the following short-term incentive goal structure for 2025:

•Customer Satisfaction (15 percent weighting) - The customer satisfaction goal focuses on our relationship with and service to our customers. We measure customer satisfaction through quarterly surveys conducted by an independent survey firm. The survey data covered five specific performance qualities: overall satisfaction, quality, value, advocacy, and loyalty. In 2025, we began to include web-based customer survey results, in addition to telephone survey results, in the customer satisfaction metric.

•Service Reliability (15 percent weighting) - The service reliability goal is intended to focus executive officers on Idaho Power’s system reliability and its impact on the company’s relationship with its customers. We measure this goal by the number of interruptions greater than five minutes in duration experienced on average by Idaho Power’s metered general customers over the course of the year.

•Adjusted Net Income (70 percent weighting) - Our compensation and human resources committee believes that the IDACORP adjusted net income goal provides the most important overall measure of our financial performance, and thus the compensation and human resources committee gave it the greatest weighting. This goal aligns management and shareholder interests by motivating our executive officers to increase earnings for the benefit of shareholders.

The table below shows the specific 2025 threshold, target, and maximum performance levels for each short-term incentive performance goal and the qualifying payout multiplier for each target. For 2025, consistent with prior years, the compensation and human resources committee evaluated our financial forecast and budgets, and from that review established a target for adjusted net income. We use linear interpolation for achievement within the performance levels specified. The table also shows the actual 2025 performance results for all three performance goals, resulting in a payout of approximately 170 percent of target. The Executive Incentive Plan under which the short-term awards are made to executives does not permit the payment of awards if there is no payment of awards under the Employee Incentive Plan (which uses the same metrics and performance levels, with different weightings) or if IDACORP does not have net income sufficient to pay dividends on its common stock. Neither of these restrictions applied for 2025.

The table that follows shows the 2025 short-term incentive award opportunities for the NEOs recommended by the compensation and human resources committee and approved by the board of directors, which increased for Mr. Richins and Mr. Buckham to 65 percent from 60 percent in 2024, as a percentage of base salary, and remained unchanged for our other NEOs, as well as the 2025 short-term incentive awards earned by our NEOs based on actual performance results for 2025. The short-term cash incentive award opportunities are calculated by multiplying base salary by the product of the approved incentive percentage and the qualifying multiplier for each goal. The amounts earned are based on actual base salary paid in 2025.

1 The percentage shown represents the percent of base salary to be awarded, assuming achievement of the relevant performance level.

Financial Performance Goal:

The compensation and human resources committee set the target level for the IDACORP adjusted net income goal for 2025 at $308 million. Factors that influenced the committee’s determination of the appropriate target level included increased depreciation and interest expense from continued elevated capital expenditures for infrastructure development; the net impact of the 2024 Idaho limited-scope rate case (2024 Limited-Issue Rate Case) and continued regulatory lag; higher operations and maintenance expenses, particularly from labor cost increases; and the revenue impacts of customer growth and normalized weather conditions. Capital expenditures for 2025 continued to be significantly elevated as compared to years before 2024, and the regulatory lag associated with delayed collection on the depreciation and financing costs on those assets through customer rates was a notable factor for consideration. To that end, the compensation and human resources committee’s review included our financial forecast and a detailed earnings sensitivity analysis prepared by management, which provided the committee with insight on those and other anticipated positive and negative drivers of financial performance on an income-statement basis. Notwithstanding considerable regulatory lag resulting from the 2024 Limited-Issue Rate Case and increased capital expenditures,

IDACORP, INC. 2026 PROXY STATEMENT 34

to further drive positive performance the committee established the target of the adjusted net income metric approximately $19 million above our 2024 actual net income, representing a substantial increase.

As used in the adjusted net income goal, “adjusted net income” means net income as calculated in accordance with generally accepted accounting principles, adjusted by the compensation and human resources committee to exclude the impact of non-recurring, extraordinary, or unusual events to the extent they or their respective impacts or outcomes were unrelated to management’s actions, not contemplated at the time the goal was established, and inconsistent with the original intent and objectives of the award. These include financial impacts related to acquisition, divestiture, and restructuring activities; changes in accounting principles; enactment of new federal or state laws; or impairment charges. In determining actual performance under the adjusted net income goal in 2025, the committee did not make any adjustments from net income as calculated in accordance with generally accepted accounting principles.

Operational Performance Goals:

In an effort to incentivize rigorous and realistic achievement levels, the compensation and human resources committee set the target for the customer satisfaction goal for 2025 at 83.00 percent. In setting the goal for 2025, the committee considered a variety of factors, including the company’s transition in 2025 to include web-based customer survey results, which generally are lower than telephone-only survey results, in the customer service metric and challenges from continuing rate cases.

The committee set the target for the service reliability goal for 2025 at 1.25 outage incidents. To set the goal, the committee considered the impacts of high-outage events from extreme weather conditions and other factors on service reliability. In setting the goal for 2025, the committee sought a goal realistic enough to be attainable while incentivizing continued outstanding service reliability, with the target set at a level requiring service reliability above the average level of a comparison group of other peer utilities.

Long-Term Incentive Compensation

Long-term incentive compensation is intended to encourage and reward long-term performance, provide a multi-year retention mechanism, and enhance the alignment between management and shareholders. We grant executive officers the opportunity to earn stock-based long-term compensation in order to be competitive from a total compensation standpoint, to ensure focus on long-term financial goals, to recognize future performance, to promote retention, and to maximize shareholder value by aligning our executive officers’ interests with shareholder interests. Our 2025 long-term incentive awards were allocated as follows:

•time-vesting restricted stock units, eligible to vest in January 2028, representing one-third of the awards; and

•performance-based restricted stock units with a three-year performance period of 2025-2027, representing two-thirds of the awards at target.

Consistent with our historical practice, the compensation and human resources committee recommended, and the board of directors approved, the 2025 long-term incentive grants at their February 2025 meetings, which approval became effective after we released our 2024 full-year earnings. Following is a more detailed description of the time-vesting restricted stock units and performance-based restricted stock units that comprise the long-term incentive grants.

Time-Vesting Restricted Stock Units:

The time-vesting restricted stock unit awards made to our NEOs in 2025 will vest in January 2028, as long as the NEO remains employed by us throughout the restriction period. Earned awards are settled in shares. The NEOs receive dividend equivalents on the units during the restriction period, since the officer is assured of vesting in the units as long as he or she remains employed by the company. We believe that the restricted stock units and dividend equivalent payments provide a strong incentive for the officer to continue working for us for the entire three-year restriction period. Because the restricted stock units are intended to serve as a retention tool, the compensation and human resources committee decided to use cliff vesting, rather than ratable vesting. However, if the NEO's employment terminates before the vesting date, subject to board of director approval, the officer may receive a pro-rated payout, depending on the reason for or circumstances surrounding the termination, such as for retirement at age 55 or older.

Performance-Based Restricted Stock Units:

Performance-based restricted stock units are based entirely on our financial performance over a three-year performance period and may be earned up to 200 percent of target but will not be earned if our minimum financial performance goals are not met at the end of the performance period. Earned awards are settled in shares. Dividend equivalents on the performance-based

IDACORP, INC. 2026 PROXY STATEMENT 35

restricted stock units are not paid to our NEOs during the performance period. Instead, they are paid at the end of the performance period only on performance-based restricted stock units that are actually earned, if any.

The performance-based restricted stock units granted in February 2025 may be earned by the NEOs based on performance against two financial measures over the 2025-2027 performance period. The two equally weighted performance measures are CEPS and TSR. The CEPS levels are indicative of management performance, as this goal relates to revenue enhancement and cost containment. Relative TSR is determined by our common stock price change and dividends paid over a three-year performance period compared to that achieved by a comparison group of companies over the same three-year period. As in prior years, for 2025 grants, we used the EEI Utilities Index as the TSR comparison group. We compare our TSR with these companies' TSRs on a percentile basis.

The CEPS performance levels for the 2025-2027 performance period are as follows:


			-Threshold:			$15.00
			-Target:			$16.00
			-Maximum:			$17.00

The TSR performance levels for the 2025-2027 performance period are as follows:


			-Threshold:			30th percentile
			-Target:			55th percentile
			-Maximum:			90th percentile

The table that follows shows the long-term incentive award opportunities recommended by the compensation and human resources committee and approved by our board of directors for 2025 for each NEO. We use linear interpolation for achievement within the levels specified.

			Maximum:	2,732	(86.7)%	Maximum:	$390,000

As with base salary and short-term incentive opportunities, the compensation and human resources committee established the 2025 long-term incentive opportunities based on its review of the market compensation analysis and individual executive officer experience and tenure and both individual and company performance. Following its review, the compensation and human resources committee maintained the 2025 target long-term incentive award opportunities as a percentage of base salary at the same levels as 2024. In making its decisions, the compensation and human resources committee considered each individual’s accomplishments, as reflected in their annual performance evaluations, market compensation levels, and retention.

Other Benefits

We make available general employee benefits for medical, dental, and vision insurance, and disability coverage to employees, including our NEOs. Other benefits include the availability of an executive deferred compensation plan and limited perquisites. We believe these other benefits, though limited, contribute to a competitive executive compensation program.

Role of Our Compensation and Human Resources Committee, Management, and Compensation Consultant

The compensation and human resources committee is responsible for overseeing executive compensation and making recommendations to the board of directors for establishing appropriate salary and incentive compensation for our executive officers, including our NEOs, in accordance with our compensation philosophy, while also aligning our executives’ interests with company and business unit performance, business strategies and initiatives, and drivers for growth in shareholder value. The compensation and human resources committee is further responsible for administering our compensation plans in a manner consistent with these objectives. In this process, the compensation and human resources committee evaluates information provided by its independent compensation consultant and our management team, as discussed below. During 2025, the compensation and human resources committee engaged the services of Pay Governance LLC (Pay Governance) as the compensation and human resources committee’s independent compensation consultant. The compensation and human resources committee reviews the mix and level of compensation by each component individually and in the aggregate. The compensation and human resources committee also reviews all elements of officer remuneration, including accumulated pension benefits and change-in-control agreements.

The compensation and human resources committee and board of directors are responsible for establishing the compensation of the NEOs. Neither the CEO nor any other NEO makes recommendations for setting his or her own compensation. The recommendation of the CEO’s compensation is determined in compensation and human resources committee meetings during an executive session and is presented to the independent members of our board of directors for review and approval. Annually, the compensation and human resources committee also reviews the goals and targets of executive incentive compensation programs with a focus on setting challenging, but realistic, targets to drive performance and to improve shareholder value over the long term.

The CEO, with guidance from our Human Resources department, typically makes recommendations to the compensation and human resources committee with respect to the compensation of the other NEOs and the other company officers and senior managers. The CEO possesses insight regarding individual performance, experience, future promotion potential, and intentions in retaining particular senior executives. The CEO presents his or her recommendations to the compensation and human resources committee for review. However, the compensation and human resources committee may modify or disregard the CEO’s recommendations. Pay Governance, as discussed below, regularly provides market-level commentary and observations regarding compensation adjustments to the compensation and human resources committee. Management and the compensation and human resources committee also monitor succession plans as described below under “Executive Succession Planning.”

The compensation and human resources committee also engaged Pay Governance to provide independent advice with respect to executive and director compensation and corporate governance matters related to executive compensation. The compensation and human resources committee relied on Pay Governance’s expertise in benchmarking and familiarity with competitive compensation practices in the utility and general industry sectors. In addition, the compensation and human resources

IDACORP, INC. 2026 PROXY STATEMENT 37

committee regularly requested advice from Pay Governance concerning the design, communication, and implementation of our incentive compensation plans and other programs. In 2025, the compensation and human resources committee elected to meet with Pay Governance without management (including the CEO) present in an executive session after some of the regularly scheduled compensation and human resources committee meetings.

The services provided by Pay Governance to the compensation and human resources committee in 2025 included:

•Review of our compensation philosophy, including the alignment of our executive compensation practices with our compensation philosophy and assessing potential changes to address trends in market practice and shareholder expectations;

•Review of our peer groups used for compensation benchmarking purposes for executives and directors;

•Participation in discussions with management and the compensation and human resources committee when incentive goals were assessed and set, including:

◦Evaluation of our historical, recent, and projected performance; and

◦Analysis of historical and projected peer data and trends;

•Analysis of competitive compensation practices for executives and directors within our peer groups;

•Review of all aspects of our short-term and long-term incentive plan designs, including measures, weightings, leverage, and equity mix;

•Review of change-in-control benefits to help ensure alignment with our compensation philosophy and competitive practice; and

•Preparation for and attendance at all compensation and human resources committee meetings, including executive sessions, if applicable and as requested.

The compensation and human resources committee has considered the independence of Pay Governance, as required by SEC and NYSE rules and requirements. The compensation and human resources committee obtained and considered representations from Pay Governance that they were an independent consultant and that there were no conflicts of interest. The compensation and human resources committee also considered and assessed relevant factors that could give rise to a potential conflict of interest with respect to Pay Governance and their work. Based on this review, the compensation and human resources committee is not aware of any conflict of interest that has been raised by the work performed by Pay Governance.

Post-Termination Compensation Programs

Idaho Power Company Retirement Plan

The Idaho Power Company Retirement Plan is a defined-benefit pension plan available to our employees. We discuss the material terms of the plan later in this proxy statement in the narrative following the “Pension Benefits for 2025” table. Because benefits under the plan increase with an employee's continued service and earnings, the compensation and human resources committee believes that providing a pension serves as an important retention tool by encouraging our employees to make long-term commitments to the company.

Idaho Power Company Security Plans for Senior Management Employees

We have two nonqualified defined benefit plans that provide supplemental retirement benefits for certain key employees beyond our retirement plan benefits - the Security Plan for Senior Management Employees I, or Security Plan I, and the Security Plan for Senior Management Employees II, or Security Plan II. We have two separate plans to take advantage of grandfathering rules under Section 409A of the Internal Revenue Code. The compensation and human resources committee views these supplemental retirement benefits as a key component in attracting and retaining qualified executives. Benefits under the security plans continue to accrue for up to 25 years of continuous service at an executive officer level. Because benefits under the security plans increase with period of service and earnings, the compensation and human resources committee believes that providing a supplemental pension under these plans serves as an additional retention tool that encourages our executives to make long-term commitments to the company. The security plans provide income security for our executives and are balanced with the at-risk compensation represented by our incentive plans. We discuss the other material terms of the security plans later in this proxy statement in the narrative following the “Pension Benefits for 2025” table.

Executive Deferred Compensation Plan

Our executive officers are eligible to participate in the Executive Deferred Compensation Plan, which is a nonqualified supplemental deferred compensation plan that allows participants to defer compensation in excess of certain statutory limits in the tax-qualified 401(k) plan. Participants may defer up to 50 percent of their base salary and up to 50 percent of any short-term

IDACORP, INC. 2026 PROXY STATEMENT 38

incentive compensation. The compensation and human resources committee views the plan as a supplemental benefit to attract and retain qualified executive officers. None of the NEOs participate in the plan.

Change in Control Agreements

We have change in control agreements with all of our executive officers. The compensation and human resources committee believes that change in control agreements are an important benefit to promote officer retention during periods of uncertainty around acquisitions and to motivate officers to weigh acquisition proposals in a balanced manner for the benefit of shareholders, rather than resisting such proposals for the purpose of job preservation.

The agreements we have with our NEOs are “double-trigger” agreements in the sense that two events must occur in order for full cash severance payments to be made: a change in control and a termination of employment in connection with the change in control. However, for Ms. Grow and Mr. Malmen, who entered into their agreements prior to March 2010 when we added the “double-trigger” provision to our form of change in control agreement, if a change in control occurs and the officer is not terminated, the agreements permit the officer to terminate employment for any reason during the first month following the one-year anniversary of the change in control and receive a lesser severance payout. The prior provision was historically included because the first year after a change in control is a critical transition period, and the 13th-month trigger serves as an important tool to encourage our executive officers to remain with the company or our successor for at least that transition period.

We discuss the other material terms of our change in control agreements later in this proxy statement in the section entitled “Potential Payments Upon Termination or Change in Control.”

Other Compensation Practices

Clawback Policy

The board of directors has adopted an Incentive Compensation Recovery Policy, or clawback policy, in accordance with Rule 10D-1 of the Exchange Act and the corresponding NYSE listing standards. This policy applies to our current and former executive officers as defined in Rule 10D-1, including the NEOs, and is administered by the compensation and human resources committee. In the event we are required to prepare an accounting restatement to correct a material noncompliance with any financial reporting requirement under the securities laws, including restatements that correct an error in previously issued financial statements that is material to the previously issued financial statements or that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period, the policy provides for the recovery of erroneously awarded incentive-based compensation received by our executive officers on or after the policy’s effective date, October 2, 2023. The recovery of such compensation applies regardless of whether an executive officer engaged in misconduct or otherwise caused or contributed to the requirement for a restatement.

In addition, the clawback policy in effect prior to October 2, 2023 will continue to apply to erroneously awarded performance-based compensation received prior to October 2, 2023. Under that policy, if our board of directors determines that a current or former executive officer has engaged in fraud, willful misconduct, gross negligence, or a violation of one of our policies that caused or otherwise contributed to the need for a material restatement of our financial results, the compensation and human resources committee will review all performance-based compensation earned by that executive officer during fiscal periods materially affected by the restatement. If, in the view of the compensation and human resources committee, the performance-based compensation would have been materially lower if it had been based on the restated results, the compensation and human resources committee will, to the extent permitted by applicable law, seek recoupment from that executive officer of any portion of such performance-based compensation as it deems appropriate under the circumstances. The compensation and human resources committee has sole discretion in determining whether an executive officer’s conduct has or has not met any particular standard of conduct under law or a company policy.

Our compensation policy and Corporate Governance Guidelines prohibit executive officers (as well as directors) from hedging their ownership of company common stock. Under our policy, a director or executive officer may not enter into transactions that allow the director or officer to benefit from devaluation of our stock or be the technical legal owner of our stock without the full benefits and risks of such ownership. In addition, our Corporate Governance Guidelines provide that our directors, officers, and senior managers are prohibited from pledging (through a margin feature or otherwise) our securities as collateral in order to secure personal loans or other obligations.

IDACORP, INC. 2026 PROXY STATEMENT 39

Stock Ownership and Stock Retention Guidelines

We have minimum stock ownership guidelines for our officers. Company stock ownership enhances our officers’ commitment to our future and further aligns our officers' interests with those of our shareholders. The guidelines require ownership of IDACORP common stock valued at a multiple of each officer's annual base salary, as follows:

•chief executive officer and presidents - 5x annual base salary;

•executive vice presidents and senior vice presidents - 3x annual base salary; and

•vice presidents - 1x annual base salary.

Our executives are allowed five years from the effective date of appointment to his or her position to meet these requirements. As of the date of this proxy statement, all executive officers are in compliance with the stock ownership guidelines. Performance-based RSUs are not counted toward meeting the stock ownership guidelines.

Our graduated stock ownership requirements reflect the fact that compensation is weighted more heavily toward equity compensation for our most senior positions. In circumstances where the stock ownership guidelines would result in a severe financial hardship, the officer may request an extension of time from the corporate governance and nominating committee to meet the guidelines.

We also have minimum stock retention guidelines for our officers to further align our officers' interests with shareholder interests. The guidelines state that until the officer has achieved the minimum stock ownership requirements described above, the officer must retain at least 50 percent of the net shares he or she receives from the vesting of restricted and performance-based share or unit awards, as applicable. For restricted and performance-based shares or unit awards, “net shares” means the number of shares acquired upon vesting, less the number of shares or units withheld or sold to pay withholding taxes.

Executive Succession Planning

Our board of directors is actively engaged in our succession planning for executive officers, with the goal of developing and retaining executive talent who can execute on the company's short- and long-term strategy and initiatives. As part of our succession planning efforts, management identifies high-potential executive successors, which includes a commitment to identifying and developing high-performing leaders. The company’s talent philosophy is that all leaders, regardless of level, must demonstrate the ability to motivate future performance, be accountable for their behaviors and results, perform well on our executive competencies, and enable employees to do their best every day. The executive team and the compensation and human resources committee periodically review executive succession matters and talent development. The full board of directors reviews executive succession plans at least on an annual basis. We also maintain an emergency succession plan for our CEO, as approved by our board of directors.

Impact of Tax and Accounting Treatment on Compensation Decisions

Section 409A of the Internal Revenue Code imposes additional income taxes for certain types of deferred compensation if the deferral does not comply with Section 409A. We administer our compensation plans and arrangements affected by Section 409A with the objective of not triggering any additional income taxes under Section 409A, but there can be no assurance that any such additional income taxes will not be triggered.


Compensation and Human Resources Committee Report The compensation and human resources committee has reviewed and discussed with management the Compensation Discussion and Analysis contained in this proxy statement. Based on its review and these discussions, the compensation and human resources committee has recommended to our board of directors that the Compensation Discussion and Analysis be included in this proxy statement and incorporated by reference into our Annual Report on Form 10-K for the year ended December 31, 2025.

Our Compensation Policies and Practices as They Relate to Risk Management

We annually review our compensation policies and practices for all employees to determine whether any risks arising from these policies and practices may be reasonably likely to have a material adverse effect on our company. This discussion involves a review and consideration of several of the factors set forth in Item 402(s) of Regulation S-K (17 CFR § 229) and other items. Each November, the compensation and human resources committee members discuss, together with the committee’s compensation consultant and management, the factors in Item 402(s) and consider the following additional factors relating to compensation practice risks:

•the vast majority of IDACORP’s income from continuing operations is contributed by Idaho Power, which is a regulated electric utility, and management believes its regulated operations do not lend themselves to or incentivize significant risk-taking by employees;

•our employees and executives are limited from taking operational risks by the extensive regulation of our operations by multiple agencies, including the Federal Energy Regulatory Commission and state public utility commissions;

•we use a compensation structure based on both financial and operational goals, use time-vesting shares as a portion of the long-term incentive awards, cap the maximum incentive payouts and provide a base salary to prevent undue emphasis on incentive compensation;

•we do not pay our executives a short-term incentive award if no short-term incentive payment is made to our employees;

•we benchmark compensation annually to be consistent with industry practice;

•we impose stock retention obligations, we have compensation clawback policies, and the board of directors and compensation and human resources committee retain discretion to adjust awards as they deem necessary;

•we have internal controls and standards of business conduct that support our compensation goals and mitigate risk, and we use internal and external auditing processes on a regular basis to ensure compliance with these controls and standards; and

•the compensation and human resources committee, the members of which are independent, oversees our compensation policies and practices and is responsible for reviewing and approving executive compensation, and it considers potential risks when evaluating executive compensation policies and practices.

The compensation and human resources committee also believes that the company has an extensive enterprise risk management framework and that the company’s compensation practices are not a significant factor in the overall risk profile of the company’s business. As part of its review, the compensation and human resources committee considers whether a balance between prudent business risk and resulting reward is maintained. Following its review in November 2025, the compensation and human resources committee determined that our compensation-related policies and practices are not reasonably likely to have a material adverse effect on the company.

1 Amounts in this column represent the aggregate grant date fair value of the time-vesting restricted stock units and the performance-based restricted stock units (at target) granted in each of the years shown and calculated in accordance with FASB ASC Topic 718. Consistent with FASB ASC Topic 718, the full grant date fair value for the market-related TSR component of the performance-based restricted stock units for the entire three-year performance cycle is included in the amounts shown for the year of grant and was determined using a Monte Carlo simulation model. The column was prepared assuming none of the awards will be forfeited. Additional information on the assumptions used to determine the fair value of the awards is contained in Note 7 to the consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2025, on file with the SEC.

The table below shows the grant date fair values of the CEPS component of the performance-based restricted stock unit awards granted in 2025, assuming that the highest level of performance conditions are achieved for the awards. The TSR component is a market-based award with probability of payout incorporated in the grant date fair value. Compensation cost recorded by the company over the life of the grant for the TSR award is unaffected by the performance factor ultimately achieved.

Lisa A. Grow			$2,090,348

2 Values shown represent the change in actuarial present value of the accumulated benefit under the pension plan and the Senior Management Security Plans. Assumptions included a discount rate of 5.10% for 2023, 5.70% for 2024, and 5.75% for 2025; and use of the Pri-2012 Nondisabled Annuitant, Amount Weighted, Mortality, with IRS 2024 Adjusted MP-2021 Projection Scale for 2023, 2024, and 2025 and retirement age at 62. There were no above market earnings on deferred compensation.

3 For 2025, represents our contribution to the Idaho Power Company Employee Savings Plan, which is our 401(k) plan, in the amount of $14,000 for each NEO, and a charitable match contribution for each of Ms. Grow, Mr. Buckham, Mr. Malmen, and Mr. Tatum. For 2024 and 2023, represents our contribution to the Employee Savings Plan in the amounts of $13,800 and $13,200, respectively, for each NEO, and charitable match contributions for each of Ms. Grow, Mr. Buckham, Mr. Malmen, and Mr. Tatum in 2024 and each of Ms. Grow, Mr. Buckham, and Mr. Malmen in 2023.

4 Total Without Change in Pension Value represents total compensation, as determined under applicable SEC rules, minus the amount reported in the Change in Pension Value and Nonqualified Deferred Compensation Earnings column (column h). The amounts set forth in the Total Without Change in Pension Value column differ substantially from, and are not a substitute for, the amounts required to be reported in the Total column pursuant to SEC regulations. We are presenting this supplemental column to illustrate how the compensation and human resources committee views the annual

IDACORP, INC. 2026 PROXY STATEMENT 42

compensation elements for the NEOs. While the compensation and human resources committee does review the table in its totality, we note that the change in pension value amount reported in the Change in Pension Value and Nonqualified Deferred Compensation Earnings column does not reflect current compensation and represents the present value of an estimated stream of payments to be made following retirement. The methodology used to report the change in pension value under applicable accounting rules is sensitive to external variables such as assumptions about life expectancy and changes in the discount rate determined at each year end, which are functions of economic factors and actuarial calculations that do not relate to our performance and are outside of the control of the compensation and human resources committee.

2025 Short-Term Incentive Awards

The short-term cash incentive award opportunities are calculated by multiplying actual base salary by the product of the approved incentive percentage and the qualifying multiplier for each goal. We discuss the short-term incentive award opportunities and results in more detail in the CD&A.

2025 Long-Term Incentive Awards

In February 2025, the compensation and human resources committee approved long-term incentive awards with the following two components:

•Time-vesting restricted stock units: Each NEO received an award of time-vesting restricted units equal to a percentage of her or his base salary in 2025. These units vest and are settled in shares in January 2028 if the NEO remains

IDACORP, INC. 2026 PROXY STATEMENT 43

continuously employed with the company during the entire restricted period. Dividend equivalents are paid on the shares during the restricted period and are not subject to forfeiture; and

•Performance-based restricted stock units: Each NEO received an award of performance-based restricted stock units at the target level equal to a percentage of her or his base salary in 2025. The units will vest at the end of the three-year performance period to the extent we achieve our performance goals (CEPS and TSR, weighted equally) and the NEO remains employed by the company during the entire performance period, with certain exceptions. Dividend equivalents will accrue during the performance period and will be paid in cash based on the number of shares that are earned. Performance-based restricted stock units are settled in shares and paid out in accordance with the payout percentages set forth in the CD&A.

We discuss in further detail the long-term incentive award opportunities and results in the CD&A.

Idaho Power Company Retirement Plan

Description

The Idaho Power Company Retirement Plan is a qualified, defined benefit pension plan for employees of Idaho Power, Idaho Power’s subsidiaries, and some of its affiliate companies. The plan was established in 1943 to help employees meet the important long-term goal of building for financial security at retirement. Idaho Power makes all contributions to the plan. The dollar amount of the contribution is determined each year based on an actuarial valuation.

Eligibility Standards and Vesting

Employees who are 18 years of age or older are eligible to participate once they complete 12 months of employment. Participation begins the first day of the month after meeting this requirement, with credit for purposes of vesting and term of service for the initial 12 months of employment. Employees become vested and eligible for benefits under the plan after completing 60 months of employment.

IDACORP, INC. 2026 PROXY STATEMENT 46

Retirement Age

Under the terms of the plan, normal retirement is at age 65; however, an employee may retire at age 62 without a reduction in pension benefits. Employees are eligible for early retirement when:

• they reach the age of 55 and have 10 years of credited service; or

• they have 30 years of credited service.

Employees electing to retire before reaching age 62 receive a reduced benefit as follows:


Age When Payments Begin	Reduced Benefit as a Percentage of Earned Pension	Age When Payments Begin	Reduced Benefit as a Percentage of Earned Pension
61	96%	54	62%
60	92%	53	57%
59	87%	52	52%
58	82%	51	47%
57	77%	50	42%
56	72%	49	38%
55	67%	48	34%

Benefits Formula

For employees hired before January 1, 2011, plan benefits for employees age 62 or older at the time of retirement are calculated based on 1.5 percent of their final average earnings multiplied by their years of credited service. Final average earnings is based on the employee’s average total wages – base pay plus short-term incentive compensation plus overtime – during the highest 60 consecutive months in the final 120 months of service. For employees hired on or after January 1, 2011, plan benefits are calculated based on 1.2 percent of their final average earnings multiplied by their years of credited service. Plan benefits for employees who at the time of retirement are under the age of 62 are calculated based on this same formula and are then reduced using the appropriate early retirement factor.

Joint and Survivor Options

Employees who have a spouse at retirement have a survivor option at an amount equal to 50 percent, 75 percent, or 100 percent of the employee’s benefit, or they may choose a single life benefit. Under the survivor options, the benefit payments are reduced to allow payments for the longer of two lives. The reduction factor is determined by the age difference between the employee and spouse. Under a single life benefit, no benefits will be payable to the spouse after the employee’s death.

The spouse is protected if the employee dies after being vested in the plan but before retirement. The spouse will receive a lifetime benefit payment equal to 50 percent of the benefit payment the employee had earned at the date of death. This benefit payment is calculated without an early retirement reduction and is not reduced for the age difference between the employee and the spouse. Payment commences on the date the employee could have retired had he or she survived. If the employee has 10 or more years of service at the time of death, payments would begin at age 55. With less than 10 years of service, payments would begin at age 65.

Policy on Granting Extra Years of Credited Service

We have not granted any extra years of credited service under the plan and do not have a policy on granting extra years of credited service under the plan.

Idaho Power Company Security Plans for Senior Management Employees

Description

The Idaho Power Company Security Plans for Senior Management Employees are non-qualified defined benefit plans. To meet the requirements of Section 409A of the Internal Revenue Code and to take advantage of grandfathering rules under that section, which exclude from Section 409A’s coverage certain deferrals made before January 1, 2005, we divided our original plan into two plans, which we refer to as Security Plan I and Security Plan II. Security Plan I governs grandfathered benefits and Security Plan II governs non-grandfathered benefits, which are subject to Section 409A. Benefits under Security Plan I are limited to the present

IDACORP, INC. 2026 PROXY STATEMENT 47

value of the benefits that would have been paid under the plan if the participant had terminated employment on December 31, 2004. Benefits under Security Plan II are based on services through the date of termination and are reduced by benefits under Security Plan I. Two of the key differences between the plans are:

• if required to comply with Section 409A of the Internal Revenue Code, payment of benefits under Security Plan II may be delayed for six months following termination of employment; and

• Security Plan I contains a 10 percent “haircut” provision, which allows participants to elect to receive their benefits early in exchange for a 10 percent reduction in their benefits and cessation of further benefit accruals.

The purpose of the plans is to provide supplemental retirement benefits for certain key employees. We intend the plans to aid in retaining and attracting individuals of exceptional ability by providing them with these benefits. The terms of the plans have evolved over time based on our view of common practices with respect to such plans.

Eligibility Standards and Vesting

Security Plan II was amended in November 2009 to limit eligibility to participate in the plan after December 31, 2009 to Idaho Power officers and certain key employees. Key employees participating in Security Plan II as of December 31, 2009 may continue participating in the plan if they maintain a senior manager or officer pay grade during their continuous employment with Idaho Power. Before Security Plan II was amended, eligibility to participate in the plan was limited to those key employees who were designated by their employers and approved by the plan’s administrative committee. The plan’s administrative committee is made up of the CEO and a committee of individuals that is approved by the compensation and human resources committee. Participation in the plan by Section 16 officers is approved in advance by the compensation and human resources committee. Employees who were participants as of December 31, 2009 are 100 percent vested. New plan participants after December 31, 2009, become 100 percent vested in their benefits only after five years of participation, with no partial vesting before that time.

Retirement Age

Under the terms of the plans, normal retirement age, which is the earliest age at which a participant may retire without a reduction in benefits, is 62. Participants are eligible for early retirement when they have:

• reached the age of 55; or

• completed 30 years of credited service under the Idaho Power Company Retirement Plan.

Benefits Commencement

If a participant terminates employment on or after attaining normal retirement age or after satisfying the early retirement conditions, benefits commence on the first day of the month following the termination date unless the participant is a “specified employee,” as that term is used in Section 409A of the Internal Revenue Code, in which case commencement of benefits under Security Plan II is delayed for six months or until the participant’s death, if earlier. Benefits provided to participants whose employment terminates, other than due to death, before attaining early retirement eligibility commence on the first day of the month following attainment of age 55, provided that if the participant is a specified employee, benefits under Security Plan II may not be paid within six months following termination of employment except in the event of death.

Benefits Formula

Normal retirement benefits under the combined plans equal the participant’s “target retirement percentage” multiplied by the participant’s final average monthly compensation less the amount of the participant’s retirement benefits under the Idaho Power Company Retirement Plan. Normal retirement benefits under Security Plan II are also reduced by the amount of the participant’s retirement benefits under Security Plan I. For participants in Security Plan II as of December 31, 2009, the target retirement percentage is 6 percent for each of the first 10 years of participation plus an additional 1 percent for each year in excess of 10 years, with a maximum target retirement percentage of 75 percent. For new plan participants after December 31, 2009, the target retirement percentage is equal to 5 percent for each of the first 10 years of participation plus an additional 1 percent for each year in excess of 10 years, with a maximum target retirement percentage of 65 percent. Effective January 1, 2018, the reduced target retirement percentages in the prior sentence apply to all participants in Security Plan II who are Idaho Power officers or certain specified key employees, regardless of when they commenced participation in the plan. However, if a participant has achieved a maximum target retirement percentage greater than 65 percent prior to January 1, 2018, that participant’s target retirement percentage will not be reduced to 65 percent, though the target retirement percentage will be fixed at that date. Final average monthly compensation is based on the participant’s base salary plus short-term incentive compensation, which may not exceed one times base salary for the year in which the short- term incentive compensation was

IDACORP, INC. 2026 PROXY STATEMENT 48

paid, during the 60 consecutive months in the final 10 years of service in which the participant’s compensation was the highest, divided by 60. Final average monthly compensation does not include compensation paid to a participant pursuant to a written severance agreement.

Early retirement benefits under the combined plans equal the participant’s “target retirement percentage” multiplied by the participant’s “early retirement factor” and by the participant’s final average monthly compensation, less the amount of the participant’s retirement benefit under the Idaho Power Company Retirement Plan. Early retirement benefits under Security Plan II are also reduced by the amount of the participant’s retirement benefits under Security Plan I. The early retirement factors under Security Plan I based on applicable ages are as follows:


Age When Payments Begin			Early Retirement Factor
61			96%
60			92%
59			87%
58			82%
57			77%
56			72%
55			67%

Under Security Plan II, retirement benefits are reduced in the same manner as under Security Plan I if the termination qualifies as early retirement or if the termination occurs within a limited period following a change in control.

Plan benefits for participants who are not eligible for early retirement benefits and, under Security Plan II, who do not terminate within the limited period following a change in control, are further reduced, as the participant would be entitled to the amount otherwise payable multiplied by a fraction, the numerator of which is their actual years of participation and the denominator of which is the number of years of participation they would have had at normal retirement.

Limit on Benefits Under Security Plan I

To comply with grandfathering rules under Section 409A of the Internal Revenue Code, a participant’s benefit under Security Plan I is determined based on the participant’s average monthly compensation, age, and years of participation as of December 31, 2004, and is limited to the present value of the amount to which the participant would have been entitled under the plan had termination occurred on December 31, 2004. For this purpose, it is assumed the benefits would have been paid at the earliest possible date allowed under the plan. Benefits under Security Plan I may not be increased by events occurring after December 31, 2004, such as a change in control or increases in age, compensation, or years of participation.

Form of Payment

Under the plans, once benefits commence, payments are generally made in the form of a single life annuity for the lifetime of the participant. A participant may also elect to receive actuarial equivalent payments in the form of a joint and survivor annuity benefit. The two forms of joint and survivor annuity offered are a joint and survivor annuity with payments continued to the surviving spouse at an amount equal to the participant’s benefit and a joint and survivor annuity with payments continued to the surviving spouse at an amount equal to 75 percent of the participant’s benefit, in each case subject to an actuarial adjustment to the benefit amount. Under a single life annuity, no benefits will be payable to the spouse after the participant’s death.

Under Security Plan I, if a participant dies before retirement, the beneficiary (which must be the participant’s spouse if the participant is married on the date of death; otherwise, the beneficiary may be a non-spouse) is entitled to receive an amount equal to 66 2/3 percent of the benefit that would be payable under the normal retirement benefit provisions of the plan, assuming death occurred at the later of age 62 or the date of death. Under Security Plan II, if the participant dies before retirement, the beneficiary (which may be a spouse or non-spouse) is entitled to receive an amount equal to the greater of (a) 66 2/3 percent of the benefit that would be payable under the normal retirement benefit provisions of the plan, assuming retirement occurred at the later of age 62 or the date of death, or (b) if death occurs after eligibility for early retirement, a joint and survivor annuity benefit calculated under the early retirement benefit provisions of the plan.

Under the plans, if the participant dies after retirement but before commencement of benefits, the beneficiary is entitled to receive a payout equal to 66 2/3 percent of the retirement benefit payable to the participant. Security Plan I provides that if the

IDACORP, INC. 2026 PROXY STATEMENT 49

participant is married on the date of death, the benefit will be paid to the spouse of the participant as an annuity for the life of the spouse. If the participant is not married on the date of death, Security Plan I provides that the benefit will be paid in the form of a lump sum. Under Security Plan II, the participant may elect the payment to be in the form of an annuity or lump sum to a spouse or other beneficiary.

Under the plans, if the beneficiary is a surviving spouse and the surviving spouse is 10 or more years younger than the participant, the monthly survivor benefit will be reduced using the actuarial equivalent factors to reflect the number of years over 10 that the spouse is younger than the participant. If the beneficiary is a person other than a surviving spouse, the survivor benefit payment amount will be calculated assuming the beneficiary is the same age as the participant.

Policy on Granting Extra Years of Credited Service

The plans are unfunded and nonqualified with the intention of providing deferred compensation benefits for a select group of “management or highly compensated employees” within the meaning of Sections 201, 301, and 401 of the Employee Retirement Income Security Act of 1974, as amended, or ERISA, and are therefore exempt from the provisions of Parts 2, 3, and 4 of Title I, Subtitle B, of ERISA. As such, the company is permitted to provide extra years of credited service, which the plans refer to as years of participation, at its discretion, but has not done so.

Potential Payments Upon Termination or Change in Control

The tables below show the payments and benefits our NEOs would receive in connection with a variety of hypothetical employment termination scenarios and upon a change in control. For purposes of the calculations for those tables, we assumed the change in control or terminations occurred on December 31, 2025, and used the closing price of our common stock on that date, which was $126.56. Actual amounts payable can only be determined at the time of a change in control or termination. All of the payments and benefits described below would be provided by IDACORP or Idaho Power.

The information presented below:

•Excludes base salary and short-term incentive awards, to the extent earned due to employment through December 31, 2025;

•Excludes compensation or benefits provided under plans or arrangements that do not discriminate in favor of the NEOs and that are generally available to all salaried employees. These include benefits under our qualified defined benefit pension plan, post-retirement health care benefits, life insurance, and disability benefits. The present value of the accumulated pension benefit for each NEO is set forth in the Pension Benefits for 2025 table; and

•Includes only the incremental increase in the present value of the Security Plan I and Security Plan II benefit, as applicable, that would be payable upon the occurrence of the events listed (other than upon death or disability) over the amount shown as the present value of the accumulated benefit for Security Plan I and Security Plan II in the Pension Benefits for 2025 table.

Time-Vesting and Performance-Based Restricted Stock Units

The IDACORP, Inc. 2000 Long-Term Incentive and Compensation Plan and/or the related award agreements provide that, except for retirement with the approval of the compensation and human resources committee, death, disability, or change in control, all unvested restricted stock units, whether time-vesting or performance-based, are forfeited upon termination. In the event of retirement with the approval of the compensation and human resources committee, death, or disability, the NEO receives a prorated number of restricted stock units based on the number of full months employed during the restricted/performance period. For time-vesting restricted stock units, the prorated units vest at termination. In the case of performance-based restricted stock units, the performance goals must be met at some level before the units vest and vesting only occurs after completion of the performance period. For purposes of these tables, we have assumed target performance levels would be achieved. Although vesting would not occur until after completion of the performance period, the amounts shown in the tables were not reduced to reflect the present value of the performance-based restricted stock units that could vest. In the event of a change in control, the restrictions on the time-vesting restricted stock units are deemed to have expired and the payout opportunity on the performance-based restricted stock units is deemed to have been achieved at the target level. Dividend equivalents attributable to earned performance-based restricted stock units would also be paid. Dividend equivalents accrued through December 31, 2025, are included in the amounts shown in the tables.

As the compensation and human resources committee has discretion to determine whether a voluntary termination constitutes “retirement” for purposes of the vesting of time-based and performance-based restricted stock unit awards (for NEOs over the age of 55), we have assumed for purposes of the tables that voluntary termination would constitute a retirement with approval of the compensation and human resources committee for vesting purposes if the NEO was over the age of 55 as of December 31, 2025.

Executive Incentive Plan

Our Executive Incentive Plan provides for cash-based short-term incentives that are calculated by multiplying actual base salary by the product of the approved incentive percentage and the qualifying multiplier for each goal, subject to proration in the event of termination constituting retirement, or in the event of death or disability. Unlike the IDACORP, Inc. 2000 Long-Term Incentive and Compensation Plan, the compensation and human resources committee is not required to approve proration for retirement under the Executive Incentive Plan, except for a general right to approve the annual payouts for all participants, including the right to decrease the payouts, even to zero if so elected by the board of directors.

Summary of Change in Control Agreements

We have entered into change in control agreements with all our NEOs. The agreements become effective for a three-year period upon a change in control. If a change in control occurs, the agreements provide for severance benefits in the event of termination of the NEO’s employment by IDACORP or any subsidiary or successor company, other than for cause (and not due to death or disability), or by the NEO for constructive discharge.

IDACORP, INC. 2026 PROXY STATEMENT 51

In such event, the NEO would receive:

• a lump-sum payment equal to 2.5 times his or her annual compensation, which is his or her base salary at the time of termination and his or her target short-term incentive compensation in the year of termination, or, if not yet determined at the time of termination, the prior year’s target short-term incentive compensation;

• vesting of stock options, stock appreciation rights, restricted stock, restricted stock units, performance-based shares, and performance units, with performance-based awards vesting at target levels;

• outplacement services for 12 months, not to exceed $12,000; and

• continuation of welfare benefits for a period of 24 months or, if earlier, until eligible for comparable coverage with another employer, with the NEO paying the full cost of such coverage and receiving a monthly reimbursement payment.

We define a “change in control” as:

• acquisition of 20 percent or more of our outstanding voting securities;

• commencement of a tender or exchange offer for 20 percent or more of our outstanding voting securities;

• shareholder approval or consummation, if shareholder approval is not required, of a merger or similar transaction or the sale of all or substantially all of the assets of IDACORP or Idaho Power unless our shareholders will hold more than 50 percent of the voting securities of the surviving entity, no person will own 20 percent or more of the voting securities of the surviving entity, and at least a majority of the board of directors will be composed of our directors;

• shareholder approval, or consummation if shareholder approval is not required, of a complete liquidation or dissolution of IDACORP or Idaho Power; or

• a change in a majority of the board of directors within a 24-month period without the approval of two-thirds of the members of the board.

For Ms. Grow and Mr. Malmen, the agreements also permit a NEO to terminate employment for any reason during the first month following the one-year anniversary of the change in control. We refer to this as the 13th-month trigger in the tables. In such event, the NEO would receive the same severance benefits except that the lump-sum payment equal to 2.5 times annual compensation is reduced by one-third and the welfare benefits continue for 18 months, not 24 months.

Under the agreements, “cause” means the NEO’s fraud or dishonesty that has resulted or is likely to result in material economic damage to us or one of our subsidiaries, as determined in good faith by at least two-thirds of our non-employee directors at a meeting of the board of directors at which the NEO is provided an opportunity to be heard.

A NEO is considered constructively discharged under the provisions of his or her change in control agreement if, within 90 days after the occurrence of such event, but in no event later than 36 months following a change in control, the NEO gives written notice to IDACORP or any successor company specifying one of the following events relied upon for such termination and the company has not remedied the matter within 30 days of receipt of such notice:

• IDACORP or any successor company fails to comply with any provision of the agreement;

• the NEO is required to be based at an office or location more than 50 miles from the location where the NEO was based on the day prior to the change in control;

• a reduction that is more than de minimis in:

◦base salary or maximum short-term incentive award opportunity;

◦long-term incentive award opportunity;

◦the combined annual benefit accrual rate in our defined benefit plans, unless such reduction is effective for all executive officers; or

◦long-term disability and life insurance coverage;

• our failure to require a successor company to assume and agree to perform under the agreement; or

• a reduction that is more than de minimis in the long-term disability and life insurance coverage provided to the NEO and in effect immediately prior to the change in control.

Section 280G of the Internal Revenue Code disallows a corporate tax deduction for any “excess parachute payments” and Section 4999 imposes a 20 percent excise tax payable by the NEO on any “excess parachute payments.” Generally stated, these sections apply if the change in control related payments and benefits equal or exceed 300 percent of the NEO’s prior five-year average Form W-2 income. In the event the 300 percent threshold is met or exceeded, the NEO’s “excess parachute payments” generally equal the amount by which the change in control related payments and benefits exceed 100 percent of the NEO’s prior five-year average Form W-2 income. The agreements provide that the NEO will receive the greater net benefit of (i) full severance benefits

IDACORP, INC. 2026 PROXY STATEMENT 52

with such NEO paying any Section 280G excise tax, with no gross-up for the excise taxes, or (ii) severance benefits capped at the Section 280G excise tax limit, in which case for Ms. Grow and Mr. Malmen, the company may, in its discretion in the event that the Internal Revenue Service nonetheless requires the payment of an excise tax, provide a gross-up payment related to such excise tax imposed.

1 Ms. Grow’s change in control agreement provides for a lump-sum cash severance payment of 2.5 times her base salary and short-term incentive plan target amount. Her base salary was reduced by $2,625,000 and her short-term incentive was reduced by $382,172 to avoid excise tax. In the event of a termination upon change in control, independent tax counsel would determine which benefits are reduced in order to avoid excise tax.

2 The 13th-month trigger provision in Ms. Grow’s change in control agreement provides for the payment of two-thirds of her severance payment. Her base salary was reduced by $1,240,029 to avoid excise tax. In the event of a 13th-month trigger, independent tax counsel would determine which benefits are reduced in order to avoid excise tax.

3 As of the assumed voluntary termination date of December 31, 2025, Ms. Grow was over the age of 55. To illustrate potential termination-related benefits, we have assumed Ms. Grow’s voluntary termination would constitute retirement with approval of the compensation and human resources committee for purposes of her time-vesting restricted stock units and performance-based restricted stock unit awards.

4 Ms. Grow would receive full vesting of her 2023 time-vesting restricted stock unit award and pro rata vesting of her 2024 (66.7%) and 2025 (33.3%) time-vesting restricted stock units. The dollar amount is determined by multiplying the prorated number of shares by $126.56.

5 We have assumed a not for cause termination and a for cause termination would not constitute retirement with approval of the compensation and human resources committee for purposes of Ms. Grow’s time-vesting restricted stock units and performance-based restricted stock unit awards.

6 Ms. Grow would receive full vesting of her time-vesting restricted stock unit awards and payout of the performance-based restricted stock units at target. The dollar amounts are determined by multiplying the number of shares by $126.56 and include the cash payment of dividend equivalents, as applicable.

7 Ms. Grow would receive full vesting of her 2023 award assuming the performance goals are met at the target level and pro rata vesting of her 2024 (66.7%) and 2025 (33.3%) awards assuming the performance goals are met at the target level. The amount shown assumes a share price of $126.56 and includes the cash payment of dividend equivalents.

8 The values shown represent the incremental increase in the Security Plan II benefit based on Ms. Grow's actual age and termination as of December 31, 2025, relative to the amount shown for Security Plan II in the Pension Benefits for 2025 table. We used a discount rate of 5.75% and the Pri-2012 Nondisabled Annuitant, Amount Weighted, Mortality, with IRS 2024 Adjusted MP-2021 Projection Scale. Payments would begin in July 2026 under Security Plan II.

9 In the event of death, the value represents the present value of Security Plan II death benefits.

10 Under Security Plan II, if employment is terminated within a change in control period prior to the executive officer’s normal retirement, the benefit is calculated using age 55 or the officer’s age at termination if greater than 55. The values shown represent the incremental increase in the Security Plan II benefit relative to the amount shown for Security Plan II in the Pension Benefits for 2025 table and were determined as described in footnote 8.

11 Ms. Grow’s change in control agreement provides for the continuation of welfare benefits for a period of 24 months. The value shown represents the cost to the company of continuing these benefits.

12 The 13th-month trigger provision in Ms. Grow’s change in control agreement provides for the continuation of welfare benefits for a period of 18 months. The value shown represents the cost to the company of continuing these benefits.

13 Ms. Grow’s change in control agreement provides for outplacement services commencing within 12 months of a change in control up to a maximum of $12,000 for a 12-month period.

14 The company may make a 280G tax gross-up payment to Ms. Grow if (a) she receives a claim from the Internal Revenue Service that, if successful, would require her to pay an excise tax in connection with any “excess parachute payments,” as that term is described in Internal Revenue Code Section 280G, and (b) her compensation had been reduced to avoid an excise tax. Because Ms. Grow’s compensation was reduced to avoid an excise tax in this instance (see footnote 2 above), under the terms of Ms. Grow's change in control agreement, the company may provide, but is not required to provide, such a tax gross-up upon a not for cause or constructive discharge termination, in an amount that would reimburse Ms. Grow for the excise tax, taxes imposed upon the 280G tax gross-up payment, and any interest or penalties with respect to such taxes. Such amount is not determinable unless and until Ms. Grow were to receive a claim from the Internal Revenue Service.

1 Mr. Buckham’s change in control agreement provides for a lump sum cash severance payment of 2.5 times his base salary and short-term incentive plan target amount.

2 As of the assumed voluntary termination date of December 31, 2025, Mr. Buckham was not over the age of 55. Thus, we have assumed Mr. Buckham’s voluntary termination would not constitute retirement with approval of the compensation and human resources committee for purposes of his time-vesting restricted stock units and performance-based restricted stock unit awards.

3 We have assumed a not for cause termination and a for cause termination would not constitute retirement with approval of the compensation and human resources committee for purposes of Mr. Buckham’s time-vesting restricted stock units and performance-based restricted stock unit awards.

4 Mr. Buckham would receive full vesting of his 2023 time-vesting restricted stock unit award and pro rata vesting of his 2024 (66.7%) and 2025 (33.3%) time-vesting restricted stock units. The dollar amount is determined by multiplying the prorated number of shares by $126.56.

5 Mr. Buckham would receive full vesting of his time-vesting restricted stock unit awards and payout of the performance-based restricted stock units at target. The dollar amounts are determined by multiplying the number of shares by $126.56 and include the cash payment of dividend equivalents, as applicable.

6 Mr. Buckham would receive full vesting of his 2023 award assuming the performance goals are met at the target level and pro rata vesting of his 2024 (66.7%) and 2025 (33.3%) awards assuming the performance goals are met at the target level. The amount shown assumes a share price of $126.56 and includes the cash payment of dividend equivalents.

7 Mr. Buckham would not receive a payout greater than the amounts shown for Security Plan II in the Pension Benefits for 2025 table, and thus the table reflects no enhanced value upon the applicable events. We used a discount rate of 5.75% and the Pri-2012 Nondisabled Annuitant, Amount Weighted, Mortality, with IRS 2024 Adjusted MP-2021 Projection Scale, and assumed Mr. Buckham was 55 as of December 31, 2025.

8 In the event of death, the value represents the present value of Security Plan II death benefits.

9 Under Security Plan II, if employment is terminated within a change in control period prior to the executive officer’s normal retirement, the benefit is calculated using age 55 or the officer’s age at termination if greater than 55. The values shown represent the incremental increase in the Security Plan II benefit relative to the amount shown for Security Plan II in the Pension Benefits for 2025 table and were determined as described in footnote 7. Payments would not commence until Mr. Buckham reaches age 55.

10 Mr. Buckham’s change in control agreement provides for the continuation of welfare benefits for a period of 24 months. The value shown represents the cost to the company of continuing these benefits.

11 Mr. Buckham’s change in control agreement provides for outplacement services commencing within 12 months of a change in control up to a maximum of $12,000 for a 12-month period.

1 Mr. Richins’ change in control agreement provides for a lump sum cash severance payment of 2.5 times his base salary and short-term incentive plan target amount.

2 As of the assumed voluntary termination date of December 31, 2025, Mr. Richins was not over the age of 55. Thus, we have assumed Mr. Richins’ voluntary termination would not constitute retirement with approval of the compensation and human resources committee for purposes of his time-vesting restricted stock units and performance-based restricted stock unit awards.

3 We have assumed a not for cause termination and a for cause termination would not constitute retirement with approval of the compensation and human resources committee for purposes of Mr. Richins’ time-vesting restricted stock units and performance-based restricted stock unit awards.

4 Mr. Richins would receive full vesting of his 2023 time-vesting restricted stock unit award and pro rata vesting of his 2024 (66.7%) and 2025 (33.3%) time-vesting restricted stock units. The dollar amount is determined by multiplying the prorated number of shares by $126.56.

5 Mr. Richins would receive full vesting of his time-vesting restricted stock unit awards and payout of the performance-based restricted stock units at target. The dollar amounts are determined by multiplying the number of shares by $126.56 and include the cash payment of dividend equivalents, as applicable.

6 Mr. Richins would receive full vesting of his 2023 award assuming the performance goals are met at the target level and pro rata vesting of his 2024 (66.7%) and 2025 (33.3%) awards assuming the performance goals are met at the target level. The amount shown assumes a share price of $126.56 and includes the cash payment of dividend equivalents.

7 Mr. Richins would not receive a payout greater than the amounts shown for Security Plan II in the Pension Benefits for 2025 table, and thus the table reflects no enhanced value upon the applicable events. We used a discount rate of 5.75% and the Pri-2012 Nondisabled Annuitant, Amount Weighted, Mortality, with IRS 2024 Adjusted MP-2021 Projection Scale, and assumed Mr. Richins was 55 as of December 31, 2025.

8 In the event of death, the value represents the present value of Security Plan II death benefits.

10 Mr. Richins’ change in control agreement provides for the continuation of welfare benefits for a period of 24 months. The value shown represents the cost to the company of continuing these benefits.

PROPOSAL NO. 2: Advisory Resolution to Approve Executive Compensation

As required by Section 14A of the Exchange Act, the board of directors is submitting a separate resolution to approve the compensation of our NEOs on an advisory basis. This is an opportunity for our shareholders, through what is commonly referred to as a “say-on-pay” vote, to endorse or not endorse our executive compensation program. In 2025, over 92 percent of the votes cast by our shareholders were in favor of, and we consider the results of those votes as evidence of support for, our compensation program and decisions. Those voting results were a component of our rationale for maintaining a similar approach to executive compensation for 2025. Please see Part 4 – “Executive Compensation” in this proxy statement for a more detailed discussion of our compensation programs, including plan metrics and payouts, and shareholder engagement efforts.

As described in more detail in the CD&A, the philosophy that underlies our executive compensation policy is to provide balanced and competitive compensation to our officers to (1) ensure that our company is able to attract and retain high-quality officers and (2) motivate our officers to achieve performance goals that will benefit our shareholders and customers. This philosophy is implemented in tandem with our business strategy of keeping employees safe and engaged, growing financial strength, improving the core business, and enhancing the brand. At the core of this philosophy is our pay-for-performance model, which links competitive levels of compensation to achievements of our overall strategy and business goals and predetermined objectives.

We urge our shareholders to read the CD&A in this proxy statement, which describes in more detail how our executive compensation policies and procedures operate and are designed to achieve our compensation objectives. We also encourage shareholders to review the 2025 Summary Compensation Table and other related compensation tables and narrative included in Part 4 – “Executive Compensation” of this proxy statement, which provide detailed information on the compensation of our NEOs. We believe the policies and procedures articulated in that discussion are effective in helping to achieve our goals and that the compensation of our NEOs reported in this proxy statement has contributed to our company’s success.

Accordingly, we are requesting that our shareholders approve the following advisory resolution at the Annual Meeting:

RESOLVED, that the shareholders of IDACORP, Inc. (the “Company”) approve, on an advisory basis, the compensation of the Company’s named executive officers, as disclosed in the Compensation Discussion and Analysis, the Summary Compensation Table, and the related compensation tables, notes, and narrative in the proxy statement for the Company’s 2026 Annual Meeting of Shareholders.

The vote on this resolution is not intended to address any specific element of compensation, but rather relates to the overall compensation of our NEOs, as described in this proxy statement in accordance with the SEC's compensation disclosure rules. The shareholder vote will not be binding on the company or our board of directors, and it will not be construed as overruling any decision by the company or the board of directors or creating or implying any change to, or additional, fiduciary duties for our company or our board of directors. Although nonbinding, the board of directors and the compensation and human resources committee will review and consider the voting results when making future decisions regarding our executive compensation program.

Our shareholders approved a proposal by the board of directors at the May 18, 2023 annual meeting of shareholders to hold our advisory vote on executive compensation annually, and the board of directors has adopted a policy consistent with this determination. Unless the board of directors modifies this policy, the next say-on-pay vote will be held at our 2027 annual meeting of shareholders.

Board of Directors’ Recommendation

The board of directors unanimously recommends a vote “FOR” the advisory resolution on executive compensation.

IDACORP, INC. 2026 PROXY STATEMENT 59

CEO Pay Ratio

Our compensation and human resources committee annually reviews the relationship of the median of the annual total compensation of our employees (other than our CEO) and the annual total compensation of our CEO. For 2025, our last completed fiscal year, the ratio of our CEO's annual total compensation, as reported above in the Summary Compensation Table, to the employee we identified with the median of the annual total compensation of all employees (other than the CEO), as described below, was 43:1.

For 2025, our median employee's annual base wage was $125,674, and our median employee's annual total compensation, which includes overtime, premium and supplemental pay, non-equity incentive plan compensation, change in present value of pension benefits, and 401k match, was $175,218. For 2025, the base wage of our CEO was $1,050,000, and the annual total compensation of our CEO, as reported above in the Summary Compensation Table, was $7,529,892.

We identified the median employee that was used for purposes of calculating the 2025 pay ratio as of the last payroll period in 2025, on December 31, 2025, using two factors:

•Base salary and wages paid to all full-time and part-time employees employed as of this date, as the consistently applied compensation measure and as reported in our payroll records reported to the Internal Revenue Service on Form W-2 for 2025; and

•Median years of service of employees with the same base wages, to reflect the median change in pension value for this group of employees.

As of December 31, 2025, our employee population consisted of 2,174 individuals. Equity awards were excluded from our compensation measure in identifying the median employee because we do not widely distribute annual equity awards to our employees. Approximately 3 percent of our employees receive annual equity awards. In addition, we did not make any cost-of-living adjustments in identifying our median employee because all our employees are located in the United States.

We believe the pay ratio disclosed above is a reasonable estimate calculated in accordance with SEC rules, based on our records and the methodology described above. The SEC rules for identifying the median employee and calculating the pay ratio allow companies to use a variety of methodologies and apply various assumptions. The application of various methodologies may result in significant differences in the results reported by SEC reporting companies. As a result, the pay ratio reported by other companies may not be comparable to the pay ratio we report above.

Pay Versus Performance

We are providing the following information about the relationship between compensation actually paid, as computed in accordance with Item 402(v) of Regulation S-K, to our CEO (PEO in the table below) and our other NEOs as a group (non-PEO NEOs in the table below) and certain financial performance of the company.

2 TSR is calculated by dividing the sum of the cumulative amount of dividends for the measurement period (assuming dividend reinvestment) and the difference between our stock price at the end and the beginning of the measurement period by our stock price at the beginning of the measurement period.

3 Represents the weighted peer group TSR, weighted according to the respective companies' stock market capitalization at the beginning of each period for which a return is indicated. The peer group used is the EEI Utilities Index.

4 The dollar amounts reported represent the amount of net income reflected in the company's audited financial statements for the applicable year.

5 The company selected measure is CEPS, or cumulative earnings per share, which represents a key measure of performance for the benefit of shareholders aligning executive officers' management efforts to enhance revenue and contain costs with shareholders' performance objectives.

PART 5 – AUDIT COMMITTEE MATTERS

PROPOSAL NO. 3: Ratification of Appointment of Independent Registered Public Accounting Firm

At the Annual Meeting, we will ask you to ratify the audit committee’s appointment of Deloitte & Touche LLP (Deloitte) as our independent registered public accounting firm for 2026. This firm has conducted our consolidated annual audits since 1998 and, previously, the consolidated annual audits of Idaho Power since 1932 and is one of the world’s largest firms of independent certified public accountants. We expect a representative of Deloitte & Touche LLP to be present at the Annual Meeting. He or she will have an opportunity to make a statement if they so desire and to respond to appropriate questions.

The audit committee is directly responsible for the appointment, compensation, retention, and oversight of the independent registered public accounting firm retained to audit our financial statements. The audit committee has adopted restrictions on hiring certain persons formerly associated with Deloitte into an accounting or financial reporting oversight role to help ensure Deloitte's continuing independence.

The audit committee meets annually in executive session without Deloitte present to evaluate the quality of Deloitte’s audit services and their performance, including Deloitte’s industry knowledge from an accounting and tax perspective, Deloitte’s continued independence and professional skepticism, the audit committee’s discussions with management about Deloitte’s performance, and information available from Public Company Accounting Oversight Board inspection reports. The audit committee annually considers whether the independent registered public accounting firm should be reappointed for another year. The lead engagement partner is required to rotate off the companies' audit every five years. The most recent rotation of the lead engagement partner took effect in January 2024. The audit committee is involved in the selection of the lead engagement partner.

If the selection of Deloitte is not ratified, the audit committee will consider the result a recommendation to consider selection of a different firm.

Policy on Audit Committee Pre-Approval of Audit and Non-Audit Services

In accordance with the audit committee’s charter, the audit committee is responsible for the appointment, compensation, retention, and oversight of the work of the independent registered public accounting firm engaged by the company. The audit committee reviews the independent auditors’ engagement plan, including the audit plan, scope, and procedures. We and our audit committee are committed to ensuring the independence of the independent registered public accounting firm, both in fact and in appearance. In this regard, the audit committee has established a pre-approval standard for both audit and non-audit services.

In addition to the audits of our consolidated financial statements, the independent registered public accounting firm may be engaged to provide certain audit-related, tax, and other services. The audit committee must pre-approve all services performed by the independent registered public accounting firm to ensure that the provision of those services does not impair the independent registered public accounting firm’s independence. The services that the audit committee will consider include audit services such as attest services, changes in the scope of the audit of the financial statements, and the issuance of comfort letters and consents in connection with financings; audit-related services such as internal control reviews and assistance with internal control reporting requirements; attest services related to financial reporting that are not required by statute or regulation, and accounting consultations and audits related to proposed transactions and new or proposed accounting rules, standards, and interpretations; and tax compliance and planning services.

Unless a type of service to be provided by the independent public accounting firm has received general pre-approval, it requires specific pre-approval by the audit committee. In addition, any proposed services exceeding pre-approved cost levels require specific pre-approval by the audit committee. Under the pre-approval policy, the audit committee has delegated to the chair of the audit committee pre-approval authority for services. The chair must report any pre-approval decisions to the audit committee at its next scheduled meeting. Any request to engage the independent registered public accounting firm to provide a service that has not received general pre-approval must be submitted as a written proposal to our chief financial officer with a copy to our general counsel. The request must include a detailed description of the service to be provided, the proposed fee, and the business reasons for engaging the independent registered public accounting firm to provide the service. Upon approval by the chief financial officer, the general counsel, and the independent registered public accounting firm that the proposed engagement complies with the terms of the pre-approval policy and applicable laws, rules, and regulations, the request will be presented to the audit committee or the audit committee chair, as the case may be, for pre-approval.

In determining whether to pre-approve the engagement of the independent public accounting firm, the audit committee or the audit committee chair, as the case may be, must consider, among other things, the pre-approval policy; applicable laws, rules, and regulations; and whether the nature of the engagement and the related fees are consistent with the following principles:

• the independent registered public accounting firm cannot function in the role of management; and

• the independent registered public accounting firm cannot audit its own work.

The pre-approval policy and separate supplements to the pre-approval policy describe the specific audit, audit-related, tax, and other services that have the general pre-approval of the audit committee. The term of any pre-approval is 12 months from the date of pre-approval, unless the audit committee specifically provides for a different period. The audit committee will periodically revise the list of pre-approved services, based on subsequent determinations.

For 2024 and 2025, all audit and non-audit services and all fees paid in connection with those services were pre-approved by the audit committee.

IDACORP, INC. 2026 PROXY STATEMENT 66


Report of the Audit Committee
The audit committee has reviewed and discussed the audited consolidated financial statements of IDACORP, Inc. with management.

Based on the audit committee’s review and discussions referred to above, the audit committee recommended to the Board of Directors that the audited consolidated financial statements of IDACORP, Inc. be included in our Annual Report on Form 10-K for the year ended December 31, 2025 for filing with the SEC.

PART 6 – OTHER MATTERS

Other Business

Neither the board of directors nor management intends to bring before the meeting any business other than the matters referred to in the Notice of Annual Meeting and this proxy statement. In addition, we have not been informed that any other matter will be presented to the meeting by others. If any other business should properly come before the meeting, or any adjournment thereof, the persons named in the proxy will vote on such matters according to their best judgment.

Shared-Address Shareholders

In accordance with a notice sent to eligible shareholders who share a single address, we are sending only one annual report to shareholders and proxy statement or Notice of Internet Availability, as applicable, to that address, unless we received instructions to the contrary from any shareholder at that address. This practice, known as “householding,” is designed to reduce our printing and postage costs. However, if a shareholder of record residing at such address wishes to receive a separate annual report to shareholders or proxy statement or Notice of Internet Availability, as applicable, for the 2026 annual meeting or in the future, he or she may contact our Shareowner Services Department in writing at 1221 West Idaho Street, Boise, Idaho 83702-5627, or by telephone at (800) 635-5406. Eligible shareholders of record receiving multiple copies of our annual report to shareholders and proxy statement or Notice of Internet Availability, as applicable, can request householding by contacting us in the same manner. If you own shares through a bank, broker, or other nominee, you can request householding by contacting that bank, broker, or other nominee.

We will deliver promptly, upon written or oral request, a separate copy of the annual report to shareholders, proxy statement, or Notice of Internet Availability, as applicable, to a shareholder at a shared address to which a single copy of the documents was delivered. Requests should be addressed to investor relations at the address or telephone number set forth above.

2027 Annual Meeting of Shareholders

As of the date of this proxy statement, we expect our 2027 annual meeting of shareholders to be held on May 20, 2027. Shareholders of the company may submit proposals on matters appropriate for shareholder action at meetings of the company’s shareholders in accordance with Rule 14a-8 of the SEC. To be submitted for inclusion in next year’s proxy statement, shareholder proposals must satisfy all applicable requirements of Rule 14a-8. For our 2027 annual meeting of shareholders, if you wish to submit a proposal for inclusion in the proxy materials pursuant to Rule 14a-8, you must submit your proposal to our corporate secretary on or before the close of business on December 3, 2026.

Our Amended and Restated Bylaws require that any shareholder proposal that is not submitted for inclusion in our proxy statement under Rule 14a-8, but is instead sought to be presented directly at the 2027 annual meeting of shareholders, must be received at our principal executive offices not earlier than 150 days and not later than 120 days prior to the first anniversary of the date on which we held the 2026 Annual Meeting. As a result, proposals, including director nominations, submitted pursuant to these provisions of our Amended and Restated Bylaws must be received no earlier than December 22, 2026 and no later than the close of business on January 21, 2027. The proposal must be accompanied by certain information, representations, and documentation specified in our Amended and Restated Bylaws, which you may obtain by writing to our corporate secretary. Shareholder proposals should be personally delivered or delivered by registered or certified mail, postage prepaid, to: Corporate Secretary, IDACORP, Inc., 1221 West Idaho Street, Boise, Idaho 83702-5627.

In addition to satisfying the requirements under our Amended and Restated Bylaws with respect to advance notice of any nomination, any shareholder that intends to solicit proxies in support of director nominees other than the company's director nominees in accordance with the SEC's universal proxy rules must comply with all the requirements of Rule 14a-19(b).

If a shareholder fails to meet the applicable deadlines or fails to satisfy other applicable requirements of the SEC, we may exercise discretionary voting authority over proxies we receive to vote on any such proposal as we determine appropriate.

Annual Report and Financial Statements

Our Annual Report on Form 10-K for the year ended December 31, 2025, was provided or made available to shareholders together with this proxy statement. You may obtain a copy of the Annual Report on Form 10-K (excluding exhibits) without charge upon written or oral request to Investor Relations, IDACORP, Inc., 1221 West Idaho Street, Boise, Idaho 83702-5627, telephone number (208) 388-2200.

Questions and Answers About the Annual Meeting, this Proxy Statement, and Voting

Why did I receive a notice in the mail regarding the internet availability of proxy materials instead of a full set of proxy materials?

Pursuant to rules adopted by the SEC, we have elected to provide access to our proxy materials on the internet. Accordingly, we are sending the Notice of Internet Availability to most of our shareholders. All shareholders will have the ability to access the proxy materials on a website referred to in the Notice of Internet Availability or may request a printed set of the proxy materials at no charge. Shareholders may request to receive proxy materials in printed form by mail or electronically by email on an ongoing basis by following the instructions provided in the Notice of Internet Availability.

How can I participate in the Annual Meeting?

The Annual Meeting will be held exclusively online via live webcast. To participate, you will need the control number included on your proxy card or Notice of Internet Availability. In order to attend, you must register in advance at proxydocs.com/IDA prior to the deadline of 3:00 p.m. (Mountain Time) on May 20, 2026. Upon completing your registration, you will receive further instructions via email, including your unique links that will allow you access to the meeting and will also permit you to submit questions. Please be sure to follow instructions found on your proxy card and voting authorization form and subsequent instructions that will be delivered to you via email.

Who is entitled to vote at the Annual Meeting?

You are entitled to notice of, and to vote at, the Annual Meeting if you owned shares of our common stock at the close of business on March 31, 2026. This is referred to as the “record date.” As of the record date, we had 55,408,235 outstanding shares of common stock entitled to one vote per share on all matters.

What if I have difficulties locating the control number prior to the day of the Annual Meeting?

Prior to the day of the Annual Meeting, if you need assistance with your control number and you hold your shares in your own name, please call toll-free (800) 635-5406 in the United States. If you hold your shares in the name of a bank or brokerage firm, you will need to contact your bank or brokerage firm for assistance with your control number.

At the Annual Meeting, our shareholders will consider and vote on the matters listed below. In determining how to vote, please consider the detailed information regarding each proposal as discussed in this proxy statement.

Will any other business be conducted at the Annual Meeting, or will other matters be voted on?

As of the date of this proxy statement, we are unaware of any matters, other than those listed in the Notice of 2026 Annual Meeting of Shareholders, that may properly be presented at the Annual Meeting. If any other matters are properly presented for consideration at the meeting, including, among other things, consideration of a motion to adjourn the meeting to another time or place, the persons named as proxies, or their duly constituted substitutes, will be deemed authorized to vote those shares for which proxies have been given or otherwise act on such matters in accordance with their judgment.

IDACORP, INC. 2026 PROXY STATEMENT 69

What is the difference between holding shares as a shareholder of record and as a beneficial owner?

If your shares are registered directly in your name with our transfer agent, EQ Shareowner Services, you are considered the “shareholder of record” with respect to those shares. If your shares are held by a stock brokerage account or by a bank or other nominee, you are considered the “beneficial owner” of the shares, and those shares are referred to as being held in “street name.” As the beneficial owner of those shares, you have the right to direct your broker, bank, or nominee how to vote your shares, and you should receive separate instructions from your broker, bank, or other holder of record describing how to vote your shares. You also are invited to participate in the online Annual Meeting. However, because a beneficial owner is not the shareholder of record, you may not vote these shares at the Annual Meeting unless you obtain a “legal proxy” from the broker, bank, or nominee that holds your shares, giving you the right to vote the shares at the Annual Meeting.

How can I vote my shares before the Annual Meeting?

If you hold shares in your own name as a shareholder of record, you may vote by internet or telephone before the Annual Meeting by following the instructions contained in the Notice of Internet Availability. Under Idaho law, proxies granted according to those instructions will be valid. If you request printed copies of the proxy materials by mail, you may also cast your vote by completing, signing, and dating the proxy card provided to you and returning it in the postage-paid envelope provided to you. Your vote by internet or telephone or through your mailed proxy card will authorize the individuals named on the proxy card to serve as your proxy to vote your shares at the Annual Meeting in the manner you indicate.

If you are a beneficial owner of shares held in street name, your broker, bank, or other nominee should provide you with materials and instructions for voting your shares. Please check with your broker or bank and follow the voting procedures your broker or bank provides to vote your shares.

Submitting a proxy or voting through the telephone or the internet will not affect your right to participate in the Annual Meeting.

If I am the beneficial owner of shares held in street name by my bank or broker, how will my shares be voted?

If you complete and return the voting instruction form provided to you by your bank or broker, we expect that your shares will be voted in accordance with your instructions. If you do not provide voting instructions, brokerage firms only have authority under applicable NYSE rules to vote shares on discretionary matters. The ratification of Deloitte & Touche LLP as our independent registered public accounting firm for 2026 is the only matter included in the proxy statement that is considered a discretionary matter. When a proposal is not discretionary and the brokerage firm has not received voting instructions from its customers, the brokerage firm cannot vote the shares on that proposal. Those shares are considered “broker non-votes.” Please promptly follow the instructions you receive from your bank or broker so your vote can be counted.

If I am a shareholder of record, how will my shares be voted?

All proxies will be voted in accordance with the instructions you submitted via the internet, by telephone, or, if you requested printed proxy materials, by completing, signing, and returning the proxy card provided to you. If you completed and submitted your proxy (and do not revoke it) prior to the Annual Meeting, but do not specify how your shares should be voted for one or more of the voting proposals, the shares of IDACORP common stock represented by the proxy will be voted in accordance with the recommendation of our board of directors, for those proposals for which you did not vote.

Can I vote at the online Annual Meeting?

Yes, if you participate in the online Annual Meeting by visiting proxydocs.com/IDA, you will be able to vote your shares and submit questions during the meeting. In order to attend, you must register in advance at proxydocs.com/IDA prior to the deadline of 3:00 p.m. (Mountain Time) on May 20, 2026. If you are a beneficial owner of shares and not a shareholder of record, to be able to vote at the online Annual Meeting, you must obtain a “legal proxy” from the broker, bank, or nominee that holds your shares, giving you the right to vote the shares at the Annual Meeting, as described above.

May I change or revoke my proxy?

You may change or revoke your proxy before it is voted at the Annual Meeting by (1) granting a subsequent proxy through the internet or by telephone, or (2) delivering to us a signed proxy card with a date later than your previously delivered proxy. If you participate in the virtual meeting and wish to vote online during the meeting, you may revoke your proxy at that time. You may

IDACORP, INC. 2026 PROXY STATEMENT 70

also revoke your proxy by mailing your written revocation to IDACORP’s corporate secretary at 1221 West Idaho Street, Boise, Idaho 83702-5627. We must receive your mailed written revocation before the Annual Meeting for it to be effective.

What is the “quorum” for the Annual Meeting, and what happens if a quorum is not present?

The presence at the Annual Meeting, online or by proxy, of a majority of the shares issued and outstanding and entitled to vote as of March 31, 2026, is required to constitute a “quorum.” The existence of a quorum is necessary in order to take action on the matters scheduled for a vote at the Annual Meeting. If you vote by internet or telephone, or submit a properly executed proxy card, your shares will be included for purposes of determining the existence of a quorum. Proxies marked “abstain” and “broker non-votes” also will be counted in determining the presence of a quorum. If the shares present online or represented by proxy at the Annual Meeting are not sufficient to constitute a quorum, the chair of the meeting or the shareholders may, by a vote of the holders of a majority of votes present online or represented by proxy, without further notice to any shareholder (unless a new record date is set), adjourn the meeting to a different time and place to permit further solicitations of proxies sufficient to constitute a quorum.

What is an “abstention”?

An “abstention” occurs when a shareholder sends in a proxy with explicit instructions to decline to vote regarding a particular matter. An abstention with respect to a matter submitted to a vote will not be counted for or against the matter. Consequently, an abstention with respect to any of the proposals to be presented at the Annual Meeting will not affect the outcome of the vote.

What is a “broker non-vote”?

A broker non-vote occurs when a broker or other nominee who holds shares for another person does not vote on a particular proposal because that holder does not have discretionary voting power for the proposal and has not received voting instructions from the beneficial owner of the shares. If no voting instructions have been provided by the beneficial owner, brokers will have discretionary voting power to vote shares with respect to the ratification of the appointment of the independent registered public accounting firm, but not with respect to any of the other proposals. A broker non-vote will have the same effect as an abstention and, therefore, will not affect the outcome of the vote.

What vote is required to approve each proposal?

The following votes are required for approval of each proposal at the Annual Meeting:


Proposal Number	Vote Requirement	Effect of Withholding, Abstentions, and Broker Non-Votes
1	Our directors are elected by a plurality of the votes cast by the shares entitled to vote in the election of directors.	No effect, though a “withhold” vote is relevant under our director resignation policy
2	The advisory resolution on executive compensation is approved if the votes cast in favor exceed the votes cast against the resolution.	No effect
3	The ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for 2026 is approved if the votes cast in favor exceed the votes cast against ratification.	Abstentions will have no effect; uninstructed shares are subject to a discretionary vote by a broker or other nominee

What happens if, under Proposal No. 1, a director receives a greater number of votes “withheld” than votes “for” such director?

As noted above, a plurality of votes cast by shareholders present, online or by proxy, at the Annual Meeting is required for the election of our directors. “Plurality” means that the nominees receiving the largest number of votes cast for his or her election are elected for the number of director positions that are to be filled at the meeting. However, under our director resignation policy, if a director nominee in an uncontested election receives a greater number of votes “withheld” from his or her election than votes “for” such election, the director must promptly tender a resignation to the board of directors. The board of directors will then decide whether to accept the resignation within 90 days following certification of the shareholder vote (based on the recommendation of the corporate governance and nominating committee, which is comprised exclusively of independent directors). We will publicly disclose the board of directors’ decision and its reasoning with regard to the offered resignation.

IDACORP, INC. 2026 PROXY STATEMENT 71

Who will count the votes?

An independent tabulator will tabulate the votes cast by mail, internet, telephone, or at the Annual Meeting. Our corporate secretary will act as inspector of election to certify the results.

Where can I find the voting results?

We expect to report the voting results on a Current Report on Form 8-K filed with the SEC within four business days following the Annual Meeting.

Are the votes of specific shareholders confidential?

It is our policy that all proxies for the Annual Meeting that identify shareholders, including employees, are to be kept confidential from the public. Proxies will be forwarded to the independent tabulator who receives, inspects, and tabulates the proxies. We do not intend to disclose the voting decisions of any shareholder to any third party except (a) as required by law or order or directive of a court or governmental agency, (b) to allow the inspector of election to review and certify the results of the shareholder vote, (c) in the event of a dispute as to the vote or voting results, or (d) in the event of a matter of significance where there is a proxy solicitation in opposition to the board of directors, based on an opposition proxy statement filed with the SEC.

Who will pay the cost of this solicitation, and how will these proxies be solicited?

We will pay the cost of soliciting your proxy. Our officers and employees may solicit proxies, personally or by telephone, fax, mail, or other electronic means, without extra compensation. In addition, D.F. King & Co., Inc. will solicit proxies from brokers, banks, nominees, and institutional investors or other shareholders at a cost of approximately $8,000 plus out-of-pocket expenses. We will reimburse banks, brokerage firms, and other custodians, nominees, and fiduciaries for their expenses in providing our proxy materials to beneficial owners.

What if I have further questions not addressed in this proxy statement?

If you have any questions about voting your shares or participating in the Annual Meeting, please call our Shareowner Services Department at (800) 635-5406.
