Exhibit 99.1

January 21, 2026

To Shareholders of EON Resources Inc. (“EON” or the “Company”)

Re: 2025 Year in Review – Another year to remember in EON’s growth journey

Dear Valued Shareholder:

We thank you for your continued interest and investment in our company. We would like to provide you with a preliminary summary of what we believe to be a successful 2025. The year had some big successes with the most significant being the September 9^th closing of the farmout and funding that changed our balance sheet. The year also had its challenges, and this letter summarizes both the ups and downs. At the end of the day, we believe it was a net positive year that positions EON and our shareholders for a bright future.

Looking back at 2025 and the progress we have made to date makes us proud of our management team of professionals with decades of experience in petroleum and business management. This team, with the support of the board of directors, drove to conclusion the actions that defined 2025 for EON which included:

Our team is dedicated to the hard work it takes to drive profit from oil and gas revenue for our shareholders. We believe we will accomplish the goals as we set them. This belief is why our team purchased stock in the open market during trading periods where personal trading by certain officers and directors were allowed. In December 2025, we announced that members of our team purchased an additional 1,561,000 shares of common stock, bringing total ownership among the team to approximately 10% of the outstanding shares of EON.

Recapitalization Funding Closed on September 9^th

On September 9, 2025, we closed on a total funding of $45.5 million, which we used to: settle the agreement with the seller of the GJF; retire our senior debt; and establish the farmout agreement discussed further below. More on the funding can be found in the press release announcing the closing and in our shareholder letter describing the recapitalization of EON. The funding was a combination of volumetric funding instruments, a farmout of our San Andres rights, the sale of overriding royalty interests in GJF, and certain compromises with creditors resulting in financial successes that included the following:

The funding significantly improved our debt and equity position and potentially opens up opportunities for future acquisitions and funding sources for the development of our properties.

Farmout of the San Andres Formation in the Grayburg-Jackson Field

On September 9, 2025 in conjunction with the funding close, the Company entered into a Farmout Agreement (the “Farmout”) with a subsidiary of Virtus Energy Partners, LLC (“Virtus”). Under the terms of the Farmout, Virtus acquired the right to develop the Company’s San Andres formation within the GJF. Virtus believes there are as many as 92 horizontal drilling locations that are prospective. A subsidiary of Virtus will be the designated operator of the horizontal wells and lead the development efforts. More information can be found in our press release announcing the Farmout, and on the page of the EON website for the GJF operations.

Virtus specializes in horizontal drilling in the Permian Basin. Virtus will concentrate on one of four main producing horizons in the San Andres formation. According to the U.S. Geological Survey, this is the most prolific reserve of hydrocarbons in the Permian Basin with an estimated production potential of 3.9 billion barrels. We have been working with Virtus in selecting locations to begin drilling horizontal wells in the San Andres formation in 2026. We are working with the regulatory authorities on drilling permits now. We expect permitting to be completed in the second quarter of 2026, with drilling to commence shortly thereafter. Key aspects of the Farmout plans for 2026 and beyond are:

Drilling and completions under the Farmout is expected to result in production and cash flow in the third quarter of 2026 and is forecasted to have significant benefits to EON. More information on the horizontal drilling program can be found in our latest Horizontal Drilling deck located on the EON website for the GJF operations.

The development of our Grayburg-Jackson oil field (“GJF”)

The GJF was EON’s first acquisition in November 2023. The GJF was acquired because of the potential of the waterflood program, which is primarily in the Seven Rivers interval. We still see significant potential from the waterflood in addition to the expected significant upside from the horizontal program under the Farmout arrangement. The GJF comprises approximately 13,700 contiguous leasehold acres where the leasehold rights range from as shallow as 1,500 feet to 4,000 feet in depth, and has original-oil-in-place (“OOIP”) of approximately 956 million barrels of oil. To start tapping into the upside potential, the Company has had to spend two years stabilizing the production and upgrading the infrastructure due to the condition of the field at acquisition date. We made significant progress in 2025, and are now at a point where we have started to expand the production by tapping into the non-producing reserves. Key aspects of the GJF in 2025 are:

The work on the GJF for the waterflood program has put us in good position to start to significantly improve production as we enter 2026. The main repairs and upgrades to the field were substantially complete by the end of 2025. The workovers and activation of idle and down wells have brought 60 idle wells back into service. Along with the knowledge gained on RCS fracs and acid stimulations has been valuable to our path forward. For more information on the property can be located on the Grayburg-Jackson Field page of our website.

Other actions to better EON for the future

Summary

In 2025, we focused on driving growth and investing in infrastructure to make EON a stronger company while still working toward increasing the overall value of the company and progressing toward profitability. We had a defining moment in September closing on the recapitalization funding and establishing the San Andres horizontal drilling program Farmout agreement. We cannot be any prouder of our team with their dedication and hard work to achieve these results in such a short period of time.

Looking forward, we are exploring opportunities to increase production, and control and reduce costs on existing operations to maximize the value to you, our shareholders.

We are excited about EON’s future, and are confident in our ability to deliver value and profit to you, our shareholders. We thank you for investing in our company, and for your ongoing loyalty and support. We look forward to have you onboard and enjoy the next phase of our growth journey.

Sincerely,

January 21, 2026
