About Hannon Armstrong Sustainable Infrastructure Capital, Inc.

Hannon Armstrong Sustainable Infrastructure Capital, Inc. (NYSE: HASI) is a US-based specialty investor focused on financing and owning assets that support the energy transition. Headquartered in Annapolis, Maryland, in the United States, the company has built a differentiated platform around sustainable infrastructure investments, emphasizing long-duration, recurring cash flows and structured capital solutions. Its core model is to partner with clients through equity investments, joint ventures, lending, land ownership, and other financing transactions.

That change did not alter the underlying strategy: HASI remains focused on financing real assets that help reduce greenhouse-gas emissions and advance decarbonization across the US economy. Its business is explicitly tied to the climate-transition theme, which makes it one of the more specialized public market platforms in the clean infrastructure space.

In practical terms, the company finances residential solar and storage, community/commercial/industrial solar and storage, utility-scale solar, onshore wind, battery energy storage systems, renewable natural gas, fleet decarbonization, energy efficiency, and ecological restoration. This broad but still focused mix gives HASI exposure to multiple parts of the energy transition while avoiding overreliance on a single technology or end market.

That positioning allows it to compete with banks, private credit providers, infrastructure funds, and tax-equity style capital sources, while leveraging expertise in contracted cash flows and project-level risk assessment. The company’s footprint is primarily US-centric, with its headquarters in Annapolis and additional office presence in New York.

In full-year 2025, HASI reported record new investments of $4.3 billion and a pipeline above $6.5 billion, signaling continued deal flow. In February 2026, it priced $600 million of green junior subordinated notes to help refinance borrowings and optimize its balance sheet. Over the past months, HASI also expanded its long-term partnership with Sunrun through a joint venture that can reach $500 million, and disclosed a major $1.2 billion investment in the SunZia project, a large-scale renewable infrastructure transaction.
