• A REIT for sustainable energy infrastructure, much like American Tower (AMT) is a REIT for cell towers.
• A specialized financier for climate-friendly projects, similar to a dedicated arm of Brookfield Asset Management focused exclusively on green infrastructure.

• Debt and Equity Investments: Hannon Armstrong provides various forms of capital, including senior debt, mezzanine debt, and equity, to finance sustainable infrastructure projects.

HA Sustainable Infrastructure Capital (symbol: HASI) primarily sells its capital solutions and services to **other companies** within the sustainable infrastructure market. As a REIT, HASI provides financing and makes investments in projects that reduce carbon emissions and increase resilience to climate change.

Their "customers" are typically project developers, sponsors, utility companies, and large corporate or governmental entities that are undertaking sustainable infrastructure projects. HASI partners with these entities by providing various forms of capital (debt, equity, preferred equity, etc.) for projects such as:

• Utility-scale renewable energy (wind, solar)
• Energy efficiency upgrades (commercial, industrial, government)
• Distributed generation and storage
• Sustainable infrastructure (e.g., water, waste, resilience)

While HASI's business model involves a diverse portfolio of investments across numerous projects and partners, and no single customer typically accounts for a significant majority of its revenue in a traditional sense, the following are examples of major types of companies and prominent specific companies they have partnered with or provided capital to:

• NextEra Energy, Inc. (Symbol: NEE) - Through its subsidiary NextEra Energy Resources, a leading developer and operator of renewable energy projects in North America.
• The AES Corporation (Symbol: AES) - A global power company that develops, owns, and operates a diverse portfolio of generation and distribution businesses, including a significant focus on renewable energy and energy storage.
• Dominion Energy, Inc. (Symbol: D) - A major electric and natural gas utility company in the U.S. that invests heavily in renewable energy and sustainable infrastructure projects.
• Other major project developers, large utilities, and financial institutions that originate and manage sustainable infrastructure assets.

The clear emerging threat for HA Sustainable Infrastructure Capital (HASI) is the **disintermediation by large institutional investors**. Increasingly, significant capital providers such as pension funds, sovereign wealth funds, and major asset managers are building out their own specialized in-house teams and capabilities for directly sourcing, structuring, and investing in sustainable infrastructure projects. This trend allows these large investors to bypass traditional financial intermediaries and specialized lenders like HASI, potentially reducing HASI's deal flow, compressing margins for its balance sheet investments, and diminishing opportunities for its third-party asset management services. As these capital giants internalize expertise and directly deploy vast sums into the sector, HASI's unique value proposition as a specialized financier could be eroded.

Here are 3-5 expected drivers of future revenue growth for HA Sustainable Infrastructure Capital (HASI) over the next 2-3 years:

1. Increased Investment Volumes and Robust Pipeline: HASI anticipates a significant increase in new transaction closings. Management expects to close over $3 billion in new transactions for the full year 2025, representing a more than 30% year-over-year increase. The company also maintains a strong pipeline exceeding $6 billion, signaling continued high investment activity.
2. Expanding Project Scale and Diversification: The company is increasingly participating in larger transactions, such as the $1.2 billion investment in the SunZia wind power project, indicating a shift towards higher transaction sizes. HASI's portfolio remains diversified across established clean energy markets, including utility-scale renewables, distributed solar, and energy efficiency projects, with emerging opportunities in sectors like data center power supply.
3. Higher Yields on New Investments and Portfolio Yield Growth: HASI has consistently achieved strong yields on new asset investments, approximately 10.5% year-to-date, which is contributing to an increase in its overall portfolio yield to 8.6% as of Q3 2025. This focus on higher-yielding assets is a primary driver for the growth in interest and securitization asset income.
4. Strategic Partnerships and Capital-Light Investment Model: The establishment of CarbonCount Holdings 1 (CCH1) in partnership with KKR, with a combined commitment of up to $2 billion for climate-positive projects, is a significant driver. This partnership enables HASI to scale its business, capitalize on its pipeline, and reduce reliance on public equity markets for growth through a more capital-light model, thereby contributing to recurring capital-light income.
5. Sustained Demand for Sustainable Infrastructure: HASI benefits from the increasing global demand for clean energy and sustainable infrastructure. As a climate-positive investment firm, the company is strategically positioned to capitalize on the ongoing energy transition and the growing need for projects that reduce greenhouse gas emissions and enhance climate resilience.

Capital Expenditures

• The company's investment strategy focuses on deploying capital primarily in income-generating real assets across utility-scale solar, onshore wind, distributed solar and storage, renewable natural gas (RNG), and energy efficiency projects.
