    ​

    On March 12, 2026, the Company’s Board of Directors authorized a $50 million increase to the Company’s share buyback program, which is expected to continue for an indefinite period of time. The primary goal of the share buyback program is to offset dilution created by the Company’s equity compensation programs.

    Purchases may be made through the open market and private block transactions pursuant to Rule 10b5-1 plans, privately negotiated transactions, or other means, as determined by the Company’s management and in accordance with the requirements of the Securities and Exchange Commission and applicable laws.

    The timing and actual number of shares repurchased will depend on a variety of factors including price, corporate and regulatory requirements, and other conditions.
