Launches www.FutureOfSilverBow.com, Providing Additional Information for Shareholders

Files Preliminary Proxy Statement and Sends Letter to Shareholders

SilverBow Resources, Inc. (NYSE:SBOW) ("SilverBow" or the "Company") today filed its preliminary proxy statement with the U.S. Securities and Exchange Commission in connection with the Company's 2024 annual meeting of shareholders (the "2024 Annual Meeting").

Also in connection with the 2024 Annual Meeting, SilverBow today sent a letter to its shareholders highlighting:

• The successful implementation of the Company's strategy to drive positive business momentum and deliver substantial shareholder value;
• Recent governance enhancements that the Company has made and that the SilverBow Board of Directors (the "Board") is proposing at the 2024 Annual Meeting to serve shareholders' best interests;
• SilverBow's extensive history of engagement with Kimmeridge Energy Management Company, LLC ("Kimmeridge") to find a path toward a value-creating transaction for ALL SilverBow shareholders;
• The Board's decision to NOT nominate the nominees put forth by Kimmeridge following a comprehensive, independent process by the Board's Nominating and Strategy Committee;
• The Board's conclusion, after consultation with its independent financial and legal advisors, that Kimmeridge's most recent proposal substantially undervalues SilverBow. The Board believes it is vital to conduct due diligence on Kimmeridge Texas Gas ("KTG"), as the Board and shareholders need relevant information to determine the actual value, not Kimmeridge's assertion of value, of the KTG assets; and
• The Board's commitment to delivering value for ALL shareholders, including continuing to engage with Kimmeridge regarding its proposed transaction.

Materials related to the 2024 Annual Meeting, including a fact sheet outlining the Company's observations on what it believes are false claims made by Kimmeridge, are available at www.FutureOfSilverBow.com.

The full text of the letter sent to shareholders today follows:

Dear Fellow Shareholders,

The Board of Directors (the "Board") and management team of SilverBow Resources, Inc. ("SilverBow" or the "Company") have been, and always will be, committed to delivering substantial value to our shareholders. We have made significant progress positioning our company to follow through on that commitment, and SilverBow's recent results underscore our belief that we have the right strategy in place to generate strong shareholder returns as the market continues to improve for our industry over the coming years.

In addition to discussing our 2023 progress and 2024 priorities, we want to highlight the recent governance enhancements we have made and those we are putting up for a vote at the 2024 annual meeting of shareholders (the "2024 Annual Meeting"). We will also touch on some additional items you will be asked to vote on this year.

Importantly, we want to set the record straight regarding what we believe are false claims made by Kimmeridge Energy Management Company, LLC ("Kimmeridge") – a fact sheet outlining our observations can be found here.

Successfully Implementing Our Strategy

SilverBow has been successfully implementing our strategy of building a scalable and durable portfolio, driving efficiencies and enhancing margins, protecting the balance sheet, and delivering profitable growth. From 2020 to 2023, we have more than doubled our portfolio to approximately 1,000 gross locations across 220,000 acres. We have driven efficiencies across our portfolio – nearly doubling our EBITDA margins¹ while almost halving our cash G&A¹ on $/Boe terms from 2020 to 2023. We have also strengthened our balance sheet by significantly reducing our leverage. We have delivered profitable growth, with corporate-level ROCE of 21%¹ over the last three years. Our strategy has proven to be resilient through market cycles and has delivered significant shareholder value, with total shareholder returns of more than 550% since 2021.

Our Positive Business Momentum

Our results are telling a clear story of the positive momentum in our business. Despite a challenging operating environment, SilverBow delivered record results across multiple metrics in the fourth quarter of 2023, including:

• Net income of $183 million, or $7.12 per share
• Non-GAAP adjusted EBITDA of $172 million¹
• Non-GAAP free cash flow of $74 million¹
• Year-over-year oil production growth of nearly 75%

Our recent and transformative acquisition in South Texas strengthened our business and provided us with a significant expansion of our capital allocation options. Our portfolio allowed us to effectively adapt to today's low natural gas prices and optimize our 2024 plan to maximize free cash flow, profitably grow oil volumes and reduce debt. The significant and deliberate steps taken by management and our Board have positioned us well.

We are confident that our strategy, ability to execute our plan and proven team will continue to drive substantial value for our shareholders in the near-and long-term.

Further Strengthening Our Board to Drive Shareholder Value

We have conducted a long-term and ongoing director search process with the assistance of a globally recognized search firm. Most recently, this process led us to announce the appointment of Leland T. "Lee" Jourdan to our Board. Lee replaces Christoph O. Majeske, who concurrently resigned from the Board following the Strategic Value Partners' ("SVP") sell down.

We are thrilled to welcome Lee to our Board. A veteran and former officer of the United States Army, he also is a distinguished public company energy executive with more than 30 years of industry experience. Lee's final executive post was being the Chief Diversity and Inclusion Officer of Chevron Corporation. He brings a demonstrated track record in international and domestic LNG markets, natural gas trading, business development and, most recently, being at the forefront of diversity and inclusion efforts at one of the world's largest energy companies.

Lee's appointment builds on our ongoing commitment to enhance the Board with new skill sets and collective experiences to help successfully execute our strategy – as well as further improve the Board's diversity profile, which is an important priority for us. Since early 2023, SilverBow has added four new independent directors.

Enhancing Our Governance to Serve Your Best Interests

Our commitment to enhancing our governance goes beyond adding new talent to our Board. We are in constant dialogue with our shareholders – we hear your feedback and value your perspectives. To that end, we are pleased to share that the Board is proposing significant governance changes at the upcoming 2024 Annual Meeting. These include proposals to:

• Declassify the Board and provide for the annual election of all directors;
• Adopt a majority voting standard in uncontested elections of directors; and
• Eliminate the supermajority vote requirements for shareholders to amend certain provisions of our certificate of incorporation.

These proposals are being made to further enhance SilverBow's governance following SVP's recent sell down in December 2023, as the Board believes that the historical post-emergence governance structure is no longer in the best interests of SilverBow shareholders.

Kimmeridge's Self-Serving Proxy Fight

At the 2024 Annual Meeting, you will also be asked to vote for either SilverBow's three highly qualified directors, or those nominated by Kimmeridge in connection with its proxy fight.

Kimmeridge has repeatedly informed SilverBow that its ultimate goal is to gain control of the Board by the 2025 annual meeting of shareholders through successive proxy fights. This could enable it to force a combination between SilverBow and Kimmeridge Texas Gas ("KTG").

Kimmeridge's assertion that we have failed to engage with Kimmeridge is absolutely false. In our March 1, 2024 letter and as a part of our preliminary proxy statement filed with the U.S. Securities and Exchange Commission (the "SEC") on March 28, 2024 (the "Preliminary Proxy Statement"), we have detailed our history of extensive engagement with Kimmeridge. Over the last two years, we have worked in good faith to find a path toward a value-creating transaction for ALL SilverBow shareholders, and not just Kimmeridge. Engagement to date includes (among others):

• 30+ meetings since June 20, 2022;
• Entry into two NDAs and an amendment to NDA to facilitate confidential information sharing;
• A proposal by SilverBow with respect to a combination with KTG in September 2022, which Kimmeridge rejected in favor of its stated goal of acquiring control of the Company through share accumulations; and
• An agreement on terms for an all-cash acquisition proposal in February 2023 – which Kimmeridge failed to consummate due to lack of financing (despite Kimmeridge's representation that its proposal was not subject to any financing contingencies and that it had confirmed financing).

SilverBow has been and continues to be open to exploring a transaction at an appropriate valuation. As with prior engagements, Kimmeridge is once again demanding that SilverBow acquire KTG on its proposed valuation and financing terms.

Interestingly, Kimmeridge has not tried to sell KTG in a competitive process, which would be a logical action to crystallize value for KTG's investors if KTG is as valuable as Kimmeridge claims it to be. Notably, Kimmeridge has not made public the relevant information for SilverBow and its shareholders to be able to independently evaluate these assets. At the same time, in case Kimmeridge is not able to force its proposed transaction in the near-term, Kimmeridge is trying to install its director nominees on the Board, in order to take control of the Company without paying an appropriate premium and have their newly appointed directors force the KTG transaction at a later date.

Our goal is to drive value, and we do not believe a wasteful proxy fight is in your best interest. Despite Kimmeridge's tactics, we offered Kimmeridge a solution where we would interview and appoint an independent board nominee with its input, among other settlement provisions. Unfortunately, Kimmeridge rejected this proposal in favor of today's proxy fight and refused to engage in any reasonable settlement that would have restricted its ability to pursue one or more wasteful proxy fights.

Voting for Directors: The Choice Is Clear

We are providing you with the facts to help you make the right decision about which director candidates to support at the 2024 Annual Meeting.

All three of Kimmeridge's nominees have close ties to or history with Kimmeridge, calling into question their independence and ability to represent the interests of all SilverBow shareholders. In addition, the Kimmeridge nominees have mixed track records that include destruction of value.

• Douglas Brooks served as a director at California Resources during Kimmeridge's campaign at the company.
• Carrie Fox has a $3 million limited partnership interest in Kimmeridge Fund VI and served as a director alongside Ben Dell, Kimmeridge's Managing Partner, at two Kimmeridge-controlled companies, Extraction Oil and Civitas Resources.
• Katherine Minyard was appointed to Ovintiv's Board as a Kimmeridge nominee.

Furthermore, the Kimmeridge nominees have been promised seats on the proposed combined company board of SilverBow and KTG. The Board believes this "special deal" conflicts Kimmeridge in independently evaluating its proposal against other potentially value-maximizing opportunities available to SilverBow. SilverBow has provided additional information about the Kimmeridge nominees at www.FutureOfSilverBow.com.

In contrast, the Company's proposed slate is made up of three independent, highly qualified directors – Gabriel L. Ellisor, Kathleen McAllister and Charles W. Wampler – with extensive public company board and executive leadership experience. Of note, Kathleen McAllister was recently added to our Board in January 2023 and joined both our Audit Committee and Nominating and Strategy Committee in May 2023. Additional information about the SilverBow nominees can be found at www.FutureOfSilverBow.com.

Our thorough assessment of the Kimmeridge nominees and our decision not to nominate them follows a comprehensive, independent process conducted by our Nominating and Strategy Committee to evaluate each of the nominees, including thorough interviews to better understand their relationships with Kimmeridge and purported qualifications.

Our Commitment to Value

The Board is committed to delivering value for ALL shareholders, and we will continue to engage with Kimmeridge regarding its proposed transaction. Following Kimmeridge's notice to nominate for three board seats in February 2024, our Board met with Kimmeridge's Managing Partner in person to continue to discuss a potential combination. It's important that you know we will only pursue opportunities that would provide full and fair value for our assets and are in the best interests of ALL SilverBow shareholders.

The Board has been reviewing Kimmeridge's proposal with respect to the most recent variation of a potential transaction between SilverBow and KTG. The Board has concluded, after consultation with its independent financial and legal advisors, that this most recent proposal substantially undervalues SilverBow. The Board has concerns over the alleged value of the KTG assets, which we believe may be overstated in a manner that would advantage Kimmeridge in a combination at the expense of our other shareholders. We believe it is vital to conduct due diligence on KTG, as the Board and the Company's shareholders need relevant information to determine the actual value, not Kimmeridge's assertion of value, of the KTG assets.

Your Support for SilverBow's Directors and Proposals at the 2024 Annual Meeting Is Critical

Your vote is critical, and we want to ensure you have all the facts to make the right choice. We encourage you to protect your investments by voting FOR the Company's proposed slate – Gabriel L. Ellisor, Kathleen McAllister and Charles W. Wampler – over Kimmeridge's conflicted nominees and AGAINST its proposal to remove a fourth director, Lee Jourdan.

We look forward to engaging with you further ahead of the 2024 Annual Meeting and hearing your perspectives. If you have any questions, please call Innisfree M&A Incorporated, SilverBow's proxy solicitor, at the number indicated below. Thank you for your continued investment in SilverBow.
