Proceeds may be used to prepay in full the second lien facility with Guggenheim Credit Services, pay related fees and expenses, finance permitted acquisitions, fund working capital and other general corporate purposes.

The facility matures on the earlier of October 24, 2030 or 91 days before the scheduled maturity of the Company’s unsecured senior notes—currently June 1, 2029—if those notes are not refinanced and that date precedes the facility maturity. The agreement includes a $35 million impact loan sublimit with rates 0.05% lower when proceeds fund renewable energy and clean transportation projects consistent with impact loan principles.

The obligations are guaranteed by material domestic subsidiaries and secured by first-priority liens on substantially all U.S.-flagged and located vessels, domestic accounts receivable, and substantially all other assets, subject to permitted liens. After the Adjustment Date tied to the fiscal quarter ending December 31, 2025, pricing ranges from Domestic Rate + 0.75%–1.25% or SOFR + 1.75%–2.25%, based on average undrawn availability. A springing financial covenant requires a fixed charge coverage ratio of not more than 1.10 to 1.00.
