SOUTH PLAINS FINANCIAL, INC.

Issuer Purchases of Equity Securities

As previously announced on February 21, 2025, the Company’s board of directors approved a stock repurchase program pursuant to which the Company may, from time to time, purchase up to $15.0 million of its outstanding shares of common stock (the “Program”). The shares can be repurchased from time to time through various means, including open market purchases and privately negotiated transactions. Open market repurchases under the Program will be conducted in accordance with the limitations set forth in Rule 10b-18 promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and other applicable legal requirements. Repurchases under the Program may also be made pursuant to a trading plan under Rule 10b5-1 under the Exchange Act, which would permit shares to be repurchased by the Company when the Company might otherwise be precluded from doing so because of self-imposed trading blackout periods or other regulatory restrictions. The extent to which the Company repurchases its shares, and the manner, timing and amount of such repurchases, will depend upon a variety of factors, including the performance of the Company’s stock price, general market and economic conditions, regulatory requirements, availability of funds, and other relevant considerations, as determined by the Company. The Company may, in its discretion, begin, suspend or terminate repurchases at any time prior to the Program’s expiration, without any prior notice. The Program does not obligate the Company to repurchase any particular number or amount of shares of the Company’s common stock and there is no guarantee as to the exact number or value of shares that will be repurchased by the Company under the Program.

The following table summarizes the share repurchase activity for the three months ended September 30, 2025.
