Item 8.01 Other Events.

On January 27, 2026, the Company’s Board of Directors approved a $2.0 billion increase to the Company's existing stock repurchase program. This approval increased the dollar amount of common stock currently available to be repurchased under the Company’s existing stock repurchase program to approximately $2.4 billion, as of January 27, 2026. The stock repurchase program is not subject to a termination date or expiration date. The repurchases may be effected from time-to-time through open market purchases, privately negotiated transactions, Rule 10b5-1 plans, accelerated stock repurchases, block trades, derivative contracts or otherwise in compliance with Rule 10b-18. The timing of any repurchases will be based on a number of factors, including available liquidity, the Company's stock price, the Company's financial outlook, and alternative investment options. The stock repurchase program does not obligate the Company to repurchase any dollar amount or number of shares and the Board may modify, suspend, or discontinue its authorization of the program at any time. The Board of Directors will continue to evaluate the size of the stock repurchase program based on CNX's free cash flow position, leverage ratio, and capital plans.
