Moody's Maintains Corporate Family Rating and Upgrades Outlook to Positive;

KBRA Maintains Issuer Rating and Outlook, Affirms Investment Grade Rating of Senior Secured Notes

Athens, Greece, June 16, 2026

Global Ship Lease, Inc. (NYSE: GSL) (the "Company" or "GSL"), a containership owner and lessor, announced today recent updates by two leading credit rating agencies. Moody's Investor Service ("Moody's") has maintained its Ba2 Corporate Family Rating, and upgraded to a positive outlook from a stable outlook. Kroll Bond Rating Agency ("KBRA") has maintained the Company's corporate rating at BB+, with a stable outlook, while also affirming the BBB/stable investment grade rating and outlook for GSL's 5.69% Senior Secured Notes due 2027.

In affirming the ratings and outlook, the agencies emphasized the Company's strong credit metrics, low leverage, and solid market position in the containership leasing space, focusing on midsized and smaller ships for which supply side fundamentals are supportive. The agencies also cited the Company's strong historical performance and resilience during industry disruptions, and its contracted revenue. In upgrading their outlook, Moody's highlighted the positive impact of the Company ordering newbuild vessels, with long-term charters attached, while monetizing older assets and maintaining a strong financial position. Additional key considerations included an experienced management team, a versatile fleet, high utilization rates, and a conservative growth strategy.

Thomas Lister, Chief Executive Officer of Global Ship Lease, commented: "We are pleased to see our credit ratings affirmed and outlook upgraded by leading credit agencies. We believe these ratings reflect the significant strength of our fortress balance sheet and charter coverage while also acknowledging the benefits of our decision to order newbuildings with long-term charters attached and to divest some of our older, non-core assets on attractive terms. Moving forward, we intend to continue to execute on our dynamic capital allocation strategy, pursuing selective and disciplined fleet renewal, returning capital to shareholders, and creating shareholder value throughout the cycle."
