Atlas Corporation

What Atlas Corporation does

Atlas Corporation is a publicly traded holding company (NYSE: ATLC) that operates through its wholly-owned subsidiary Seaspan Corporation, the world's largest containership leasing platform. Headquartered in London and domiciled in the United States, Atlas maintains a fleet of 241 vessels with approximately 2.5 million TEU of capacity on a fully delivered basis, serving major global container shipping liners through long-term time-charter agreements.

The company's core offering combines two integrated business lines: vessel leasing of large, modern, technologically advanced containerships, and ship management services including commercial management, crewing, and procurement. Its technology platform emphasizes alternative-fuel capability, with 24 LNG dual-fueled containerships as of year-end 2024 and a $226.5 million SAVER Fleet Retrofit and Upgrade Program that has completed 552 upgrades across 86 vessels, with methanol main engine conversion retrofits scheduled for mid-2026. The company has also expanded into the Pure Car and Truck Carrier (PCTC) segment with a first 10,800 CEU dual-fuel LNG vessel delivered in June 2026.

Atlas generates revenue primarily through recurring, long-term subscription-style time-charter contracts with global container liners, supplemented by professional-services revenue from integrated ship management. Its customer base includes A.P. Moller-Maersk (20+ year partnership) and Ocean Network Express, which has signed agreements to increase its ownership stake in Poseidon Corp., Seaspan's parent, to 48.9%. In 2024, Atlas divested the majority of its APR Energy assets to narrow strategic focus to the maritime leasing business.
