The full text of the letter follows:

April 9, 2024

Dear Fellow Shareholders,

The SilverBow Resources, Inc. ("SilverBow" or the "Company") Board of Directors (the "Board") and management team are committed to maximizing shareholder value. SilverBow's recent results underscore the strength of that commitment, and we have consistently delivered significant total shareholder returns with a one-year and three-year TSR of 45% and 336%, respectively outpacing the XOP E&P Index by a wide margin over near and long-term periods.¹

We also have a history of open engagement with our investors. In this spirit, we are communicating with you to provide important information regarding the decisions you will be asked to make at this year's annual meeting of shareholders (the "2024 Annual Meeting"). As you may have seen, this year, Kimmeridge Energy Management Company, LLC ("Kimmeridge") has nominated three directors with close ties to or history with its fund to replace three of the Company's directors, who have been overseeing the successful execution of the Company's proven value creation strategy.

Kimmeridge has nominated these director candidates in connection with its ongoing attempts to force a combination between SilverBow and Kimmeridge Texas Gas ("KTG") on terms that we believe undervalue the Company and are not in ALL of our shareholders' best interests. While SilverBow is open to exploring transactions with KTG at appropriate valuations, we do not believe it is in our shareholders' best interests to elect any of the Kimmeridge nominees to the Board, giving Kimmeridge undue influence over the strategic direction of the Company, including the evaluation of other potential value-maximizing opportunities.

To protect your investment, we strongly recommend that you vote using the enclosed WHITE proxy card today "FOR" all of the SilverBow independent director nominees:

• Gabriel L. Ellisor;
• Kathleen McAllister; and
• Charles W. Wampler.

WE ARE SUCCESSFULLY ADVANCING OUR LONG-TERM VALUE CREATION STRATEGY

SilverBow's outperformance has been driven by the successful execution of our strategy across four key elements:

• Investing in a scalable and durable portfolio
  • More than doubled our inventory to ~1,000 gross locations across 220,000 acres (YE20 vs. YE23); Decade+ of high-return drilling opportunities
  • Recent South Texas acquisition established SilverBow as largest pure play Eagle Ford operator with increased regional scale, balanced commodity exposure and expanded low-cost operating platform

• Driving efficiencies and enhancing margins
  • Nearly doubled EBITDA margins² while almost halving G&A² on $/Boe terms (FY20 vs. FY23)
  • Peer-leading EBITDA margins and G&A per unit reinforce status as a proven operator driving enhanced results on acquired assets

• Maintaining a strong balance sheet with deep liquidity
  • Completed $1.4B in acquisitions since year-end 2020, while increasing liquidity and significantly reducing leverage
  • Positive net income since FY21
  • Four consecutive years of free cash flow generation (FY20-FY23)
  • Committed to long-term leverage target of <1.0x

• Delivering profitable growth
  • Average three-year ROCE of 21%² (FY21-FY23)
  • Significantly increased production and FCF per share since 2020

SILVERBOW HAS A STRONG BOARD AND IS COMMITTED TO BEST-IN-CLASS CORPORATE GOVERNANCE

We believe that having a strong Board and governance practices aligned with our strategy is critical to sustained value creation. We are in constant dialogue with our shareholders – we hear and appreciate your feedback and value your perspectives. Consistent with these values, the Board is proposing significant governance changes at the upcoming 2024 Annual Meeting, including 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 supermajority vote requirements for shareholders to amend certain provisions of our certificate of incorporation.

We have a Board of value creators, with public company leadership experience, substantial sector experience, relevant financial and operational expertise, and strategic planning and risk management backgrounds.

Recently, we appointed Leland T. "Lee" Jourdan to our Board, a highly qualified director with 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 Chevron Corporation. Lee's appointment builds on our ongoing commitment to enhance the Board with new skill sets and collective experiences to successfully execute our strategy – as well as further improve the Board's diversity profile, which is an important priority for us. Also of note, Kathleen McAllister was added to our Board in January 2023 and joined both our Audit Committee and Nominating and Strategy Committee in May 2023. Since early 2023, SilverBow has added four new independent directors to our Board, while significantly increasing the Board's diversity.

KIMMERIDGE IS PURSUING A SELF-SERVING PROXY FIGHT TO FORCE A COMBINATION BETWEEN SILVERBOW AND KTG ON TERMS UNFAVORABLE TO SILVERBOW SHAREHOLDERS

Kimmeridge is pursuing a proxy fight to further its attempt to gain control of the Company and force a combination between SilverBow and KTG on terms that are unfavorable to SilverBow shareholders. Its nominations were made after two years of extensive engagement between SilverBow and Kimmeridge regarding a potential combination, and Kimmeridge's proxy fight is being pursued concurrently with its public proposal to combine the two companies. Importantly, each of Kimmeridge's nominees have been promised a board seat on the proposed combined company board, making them personally interested in rubberstamping Kimmeridge's proposed transaction instead of pursuing potential opportunities that could better enhance the Company's value.

SilverBow has been and remains open to exploring transactions at appropriate valuations. 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. Our engagement has included 30+ meetings, multiple NDAs and confidential information sharing, multiple proposals exchanged between the parties and a verbally accepted offer for an all-cash acquisition of SilverBow by Kimmeridge – which Kimmeridge failed to consummate due to its inability to obtain financing (contradicting Kimmeridge's earlier insistence that its proposal was not subject to any financing contingencies and even its assurances that it had confirmed financing).

The SilverBow Board reviewed Kimmeridge's latest proposal in consultation with its independent financial and legal advisors and determined that the proposal undervalues SilverBow and would not be in the best interests of shareholders.

THE CHOICE IS CLEAR – SUPPORT SILVERBOW'S INDEPENDENT DIRECTORS AGAINST KIMMERIDGE'S SELF-SERVING ATTEMPT TO CONTROL SILVERBOW WITHOUT PAYING FAIR VALUE TO SHAREHOLDERS

Kimmeridge's intentions are clear – it is attempting to gain control of the Board to force an undervalued transaction. Kimmeridge's decision to pursue a proxy fight serves only its own interests – and not those of ALL SilverBow shareholders.

Kimmeridge's selection of nominees exposes its self-serving agenda. 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. These connections include:

• 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.

Each of the Kimmeridge nominees has been promised a board seat on the proposed combined company board of SilverBow and KTG – a "special deal" that personally conflicts them from independently evaluating Kimmeridge's proposal against other 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.

SilverBow's Board composition achieves an ideal balance of longer-term directors possessing deep institutional knowledge with fresh perspectives from four extensively vetted and qualified directors added since 2023. This Board is committed to maintaining a diversity of perspectives and experience, and the Company's nominees – Gabriel L. Ellisor, Kathleen McAllister and Charles W. Wampler – embody that commitment. Additional information about the SilverBow nominees can be found at www.FutureOfSilverBow.com.
