14. Share Repurchases

The Covista Board of Directors (the “Board”) has authorized several share repurchase programs. Most recently, on December 15, 2025, we announced that the Board authorized Covista’s sixteenth share repurchase program, which allows Covista to repurchase up to $750.0 million of its common stock through December 15, 2028. Covista made share repurchases under its share repurchase programs as follows (in thousands, except shares and per share data):

As of September 30, 2026, $577.8 million of authorized share repurchases remained under the sixteenth share repurchase program. The timing and amount of any future repurchases will be determined based on an evaluation of market conditions and other factors. These repurchases may be made through open market purchases, accelerated share

repurchases, privately negotiated transactions, or otherwise. Repurchases will be funded through available cash balances and ongoing business operating cash generation and may be suspended or discontinued at any time. Shares of stock repurchased under the programs are held as treasury shares. Repurchases under our share repurchase programs reduce the weighted-average number of shares of common stock outstanding for basic and diluted earnings per share calculations.
