MARTEN TRANSPORT LTD Debt Disclosure

3. Long-Term Debt

In August 2022, we entered into a credit agreement that provides for an unsecured committed credit facility with an aggregate principal amount of $30.0 million which matures in August 2027. The credit agreement amends, restates and continues in its entirety our previous credit agreement, as amended. At December 31, 2025, there was no outstanding principal balance on the facility. As of that date, we had outstanding standby letters of credit to guarantee settlement of self-insurance claims of $24.1 million and remaining borrowing availability of $5.9 million. At December 31, 2024, there was also no outstanding principal balance on the facility. As of that date, we had outstanding standby letters of credit of $23.1 million on the facility. This facility bears interest at a variable rate based on the Term SOFR Rate plus applicable margins. The interest rate for the facility that would apply to outstanding principal balances was 6.75% at December 31, 2025.

Our credit agreement effective in August 2022 prohibits us from paying, in any fiscal year, stock redemptions and dividends in excess of $150 million. The current credit agreement also contains restrictive covenants which, among other matters, require us to maintain compliance with cash flow leverage and fixed charge coverage ratios. We were in compliance with all covenants at December 31, 2025 and December 31, 2024.
