Future Outlook

Management Comments

• We are pursuing our inaugural issuance of junior subordinated notes with the aims of lowering our overall weighted average cost of capital, reducing the need for future common stock issuances, and optimizing our return on equity, as well as further expanding the pool of potential capital sources for our investment funding program.
• We expect the proceeds from the Notes to help fund new investments over the near-term while limiting our common stock issuances.
• We believe we have achieved success as a leading pure play publicly-traded investor in sustainable infrastructure assets because of a number of differentiating qualities that we believe provide us with a competitive advantage in the market.
• We believe we have demonstrated the resilience of our business to grow assets and earnings and to generate attractive returns through multiple interest rate cycles and economic cycles.
• We believe that continued growth in electricity demand and generation will foster growth of our pipeline.
• We believe heightened sensitivity to prices among consumers and businesses in response to the IRA will lead to extensive efforts by businesses and policymakers to minimize inflation in energy prices.
• We believe strong momentum behind these multi-year trends will lead to elevated demand for clean energy infrastructure assets, and we provide a growing set of investment opportunities that can generate superior risk-adjusted returns.
• We believe our business model and focus, our expertise and experience, and our investment and financing strategy leave us well-positioned to capitalize on these trends and opportunities.
• We believe we are able to generate superior risk-adjusted returns in part due to our adherence to a core set of investment criteria.
• We believe we are successful at this in part by using sophisticated structures which protect our invested capital and targeted returns by giving us a preferred position in the capital structure.

Industry Context

The sustainable infrastructure market is experiencing significant tailwinds, driven by increasing U.S. power demand from data centers, manufacturing, and electrification, alongside a heightened focus on energy prices and climate change. The 'One Big Beautiful Bill Act' is expected to inject substantial capital, forecasting $1 trillion in investment from 2026-2030. HASI's focus on low-cost, fast-to-market solutions like solar and wind aligns with industry trends favoring cost-effective and rapid deployment of new generation capacity, as highlighted by Lazard's Levelized Cost of Energy report. The company's emphasis on long-term client relationships and non-competitive approach differentiates it from many capital providers in a growing, competitive market.

Comparison to Industry Standards

• Unsubsidized solar and wind energy provide the lowest levelized cost of electricity, with levelized costs of $38-$78 and $37-$86, respectively, compared to $48-$107 for natural gas (combined-cycle gas turbine), $50-$131 for utility scale solar and battery, $149-$251 for natural gas (peaking) and $141-$220 for utility-scale nuclear energy (Lazard report, June 2024).
• Solar, wind, and battery storage are the only sources of new electric capacity that can be built in less than two years, faster than traditional sources like Plant Vogtle Unit 4 (USEIA, June 2024) or nuclear plants like Three Mile Island (Reuters, October 2024).
• U.S. electricity generation was largely flat from 2000 through 2024, but is expected to double from current levels to more than 8,000 TWh by 2050, with or without the Inflation Reduction Act (McKinsey & Company, Sept. 2024).
• Over 60 GW of new renewable energy and battery storage capacity is expected to be added to the U.S. grid in 2026 (Energy Information Agency, October 2025).
• As of June 2025, 505 RNG facilities are in operation in North America industry-wide, with another 446 facilities in construction or in development.

Related Party Transactions

• Establishment of CCH1, a co-investment structure with an affiliate of Kohlberg Kravis Roberts & Co. L.P. (KKR), where each committed to invest $1 billion, later upsized to $2.6 billion total capacity.

Stakeholder Impact

• Shareholders: Potential for reduced future common stock issuances (less dilution) and optimized return on equity due to lower cost of capital.
• Creditors/Noteholders: Opportunity to invest in Green Junior Subordinated Notes with 50% equity credit, backed by a growing portfolio of sustainable infrastructure assets.

• Continued monitoring of changes in tariff policy for potential impacts to the business.
