Euroseas Ltd. Announces Order for the Construction of Two 2,800 TEU, High-Reefer Containerships

Maroussi, Athens, Greece - March 17, 2026

Euroseas Ltd. (NASDAQ: ESEA, the "Company" or "Euroseas"), an owner and operator of container carrier vessels and provider of seaborne transportation for containerized cargoes, announced today that it has signed a contract for the construction of two specialized 2,800 teu, high-reefer containerships to be built at Huanghai Shipbuilding Co., Ltd, in China. Both vessels will be built to EEDI Phase 3 and IMO NOx Tier III standards, and with over 1,000 reefer plugs, they are optimized for high-reefer density trades, providing increased capacity for refrigerated cargo, a trade with growing demand.

The vessels are scheduled to be delivered in June and August of 2028. The total acquisition price for each of the two newbuildings is approximately $46.35 million and will be financed with a combination of debt and equity. The newbuilding contract also provides the Company with the option to order up to four additional vessels of similar size, with high reefer plugs or conventional, within a short period of time.

Aristides Pittas, Chairman and CEO of Euroseas, commented: "We are pleased to announce the ordering of two modern 2,800 teu, high reefer containership vessels. With the outlook of the global refrigerated container shipping market remaining quite positive, and the limited availability of modern vessels with significant reefer capacity, we believe that this measured diversification into the specialized high-reefer segment creates an attractive opportunity within this niche market. These newbuilding orders underscore our Company's commitment to growing and modernizing our fleet, while pursuing disciplined, accretive investments designed to generate returns and enhance long-term value for our shareholders.
