What United Maritime does
United Maritime Corporation (Nasdaq: USEA) is an international shipping company specializing in worldwide seaborne dry bulk transportation. Founded in July 2022 and incorporated in the Republic of the Marshall Islands with executive offices in Glyfada, Greece, the company operates a fleet of five dry bulk vessels—comprising one Capesize, one Kamsarmax, and three Panamax—with aggregate cargo-carrying capacity of 496,242 deadweight tons (dwt). The fleet is composed entirely of Japanese-built vessels constructed between 2010 and 2016, transporting globally traded commodities including iron ore, coal, grains, and other dry bulk goods. Upon completion of the announced M/V Squireship acquisition, the operating fleet will expand to six vessels totaling 666,260 dwt.
The company generates revenue through time charters (fixed-period contracts with set daily hire rates), voyage charters (per-trip arrangements indexed to prevailing freight rates), and bareboat charter arrangements. Its customer base consists primarily of international commodity traders, mining companies, and agricultural producers, engaged via direct sales relationships. Additional income sources include bareboat-out arrangements to third parties and earnings from minority equity stakes in joint ventures. United Maritime has executed multiple asset transactions in 2025–2026 to optimize fleet composition, including the sale of M/V Cretansa for $14.7 million and the divestiture of a Norwegian joint venture stake for approximately €13.0 million in February 2026.
United Maritime was founded by Stamatios Tsantanis, who simultaneously serves as Chairman and CEO of Seanergy Maritime (Nasdaq: SHIP), a larger dry bulk operator. The CFO, General Counsel, and two independent directors of United Maritime also hold equivalent positions at Seanergy, creating substantial management overlap between the two Nasdaq-listed shipping companies. United Maritime maintains a shareholder return program consisting of quarterly cash dividends (with the Q1 2026 dividend increased to $0.10 per share, up from $0.01) and opportunistic share repurchases. The company filed its 2025 Annual Report on Form 20-F with the SEC in April 2026 and reported $37.78 million in revenue for the nine months ended September 30, 2025.

United Maritime partnerships and signals
Strategic signalPartnerships
Two partnerships are on record, tiered core and minor.
- Seanergy Maritime HoldingscoreUnited Maritime entered into an 18-month bareboat charter agreement with Seanergy Maritime Holdings for a 2010-built Japanese Capesize dry-bulk vessel of 181,453 dwt (M/V Dukeship). Both companies share senior management including CEO Stamatios Tsantanis and CFO Stavros Gyftakis. This partnership materially upgrades United Maritime's earnings profile and enhances free cash flow potential.
- Norwegian Joint Venture (Energy Construction Vessel)minorUnited Maritime sold its early-stage investment in a Norwegian joint venture that owns an Energy Construction Vessel under construction. The sale generated approximately €13.0 million. This represents a strategic divestment from offshore vessel investments as part of the company's capital strategy.

United Maritime competitors and assessment
Company assessmentDirect peers
- Safe Bulkers: NYSE-listed (SB) dry bulk owner-operator of Panamax, Kamsarmax, Post-Panamax, and Capesize vessels. Highly comparable in vessel class exposure (particularly Panamax and Kamsarmax), Greek-shipping management structure, and focus on Japanese-built modern tonnage.
- Genco Shipping & Trading: NYSE-listed (GNK) dry bulk shipper with a diversified fleet of Capesize, Ultramax, and Supramax vessels. Directly comparable business model of time/voyage chartering dry bulk tonnage to commodity traders, miners, and producers globally.
- Star Bulk Carriers: Major Nasdaq-listed dry bulk shipper (SBLK) operating 100+ Newcastlemax/Capesize/Supramax vessels. Directly comparable in core business (international dry bulk seaborne transportation of iron ore, coal, grains) and customer base (commodity traders, miners), but at materially larger scale than United Maritime.
- Golden Ocean Group: Nasdaq-listed (GOGL) dry bulk shipper with a fleet of ~90 Newcastlemax, Capesize, and Panamax vessels. Operates in the same dry bulk segments (Capesize, Panamax) as United Maritime with a similar time/voyage charter revenue model, though at much larger scale.
- Pacific Basin Shipping: HKEX-listed (2343) dry bulk owner with Handysize, Supramax/Ultramax, and Panamax vessels. Explicitly referenced in United Maritime's investor materials as a comparable; serves the same commodity trader/miner customer base with a focus on minor bulks and regional dry bulk trades.
- Seanergy Maritime Holdings: Closest comparable: shares the same CEO (Stamatios Tsantanis), CFO, General Counsel, and multiple board members with United Maritime. Operates a larger Capesize-focused dry bulk fleet (3.0M+ dwt) on Nasdaq under SHIP, providing the same commodity exposure, charter structure, and management approach. United Maritime is effectively a satellite platform of Seanergy.
- Diana Shipping: NYSE-listed (DSX) dry bulk owner with a fleet of Capesize, Kamsarmax, Panamax, and Ultramax vessels. Highly comparable in vessel mix (including Kamsarmax and Panamax segments that overlap with United Maritime) and time charter-oriented revenue model targeting major commodity houses.
- Grindrod Shipping: Small-cap dry bulk owner-operator (GRIN, taken private in 2022) with Handysize and Supramax tonnage focused on Atlantic and Pacific dry bulk trades. Comparable scale and small-fleet operating model to United Maritime, though operating in different vessel size classes.
- Pangaea Logistics Solutions: Nasdaq-listed (PANL) dry bulk shipper focused on niche high-margin trades (ice-class, project cargo, specialty bulks). Comparable in size and dry bulk focus, though differentiated by trade mix and ice-class vessel specialization.
- Eagle Bulk Shipping: US-listed (EGLE) dry bulk owner-operator of Supramax/Ultramax vessels. Comparable in fleet composition strategy (modern Japanese-built tonnage), customer base, and capital allocation focus on shareholder returns via dividends and buybacks.
