Previous report

during the first quarter of 2026. Repurchases are subject to the terms of the Company’s 2024 Credit Facility, as amended, which limits aggregate share repurchases to $15 million and subjects such repurchases to compliance with specified financial covenants and leverage requirements. Based on the foregoing, the Company has $40.2 million remaining authorized for future repurchases. The amount and timing of repurchases are subject to a variety of factors including liquidity, cash flow, stock price, compliance with our credit facility and general business and market conditions. We may also from time to time, enter into Rule 10b5-1 plans to facilitate repurchases of our shares under this authorization. The Repurchase Program may be modified, increased, suspended, or discontinued at any time. The Repurchase Program is being funded using cash on hand and cash from operations.
