Enpro Inc.

Share Repurchase Authorization

Enpro’s Board of Directors approved a new share repurchase authorization in October 2026, replacing the previous $50 million authorization that recently expired. No shares were purchased under the prior repurchase program. Under the replacement authorization, which is identical to the prior authorization, the company may repurchase up to $50 million of shares in both open market and privately negotiated transactions. The company’s management is authorized to determine the timing and amount of any such repurchases based on its evaluation of market conditions, capital alternatives, and other factors. Repurchases may also be made under Rule 10b5-1 plans, which permit the company to repurchase shares when it otherwise would be precluded from doing so under insider trading laws. The renewed share repurchase authorization expires in October 2028.
