Letter from the CEO 
Dear Stakeholders:
As I reflect on 2024 and the first few months of 2025, 
there is certainly no shortage of significant worries and 
challenges, including the continued devastating impacts of 
climate change, concerns regarding the viability of certain 
energy transition business models, a lack of consensus 
regarding the direction of our country, and heightened 
economic uncertainty. It would be rather easy and natural 
to allow these concerns to overwhelm us, resulting in fear 
and inaction. 
However, I remain optimistic about the future of our 
country, our progress on climate change, and the 
prospects for our company. This optimism is derived from 
our shared history of utilizing ingenuity, collaboration, 
and decency to overcome major challenges. It is also 
inspired by our incredible team at HASI and their 
dedication and commitment to our mission, values, 
and profitability. 
Disruption creates opportunity. New companies, 
platforms, and technologies continue to emerge, 
and business conditions and market fundamentals 
remain generally positive. Energy transition 
investment opportunities are abundant, and we 
are poised to accelerate our growth. 
The policy uncertainty that is currently a pervasive element 
of the conversation is indeed meaningful. However, policy 
matters do not alter certain economic realities currently 
driving our business. 
First, rapid growth in U.S. electricity demand is now 
beginning to accelerate after 20 years of near-zero 
growth. Second, clean energy is the fastest and least 
expensive way to supply this growing demand and avoid 
dramatic increases in power prices. Since avoiding 
energy price spikes and corresponding inflation remain 
consensus priorities, it is logical to expect clean energy 
development to continue, if not accelerate, as part of an 
all-of-the-above U.S. energy strategy. This growth in clean 
energy will require billions of dollars of capital investment. 
Therefore, we remain confident and enthusiastic about our 
future opportunities to invest. 
Against this backdrop, I could not be prouder of our 
team’s transformative accomplishments in 2024. We 
entered the year with investor concerns, including our 
access to capital and our ability to navigate elevated and 
volatile interest rates. We responded by consummating 
our $2 billion CarbonCount Holdings 1 partnership with 
KKR, achieving a second investment grade rating, and 
significantly increasing the capacity of our bank credit 
facilities. Our capital and liquidity strategy has provided 
us with financial strength unparalleled in our corporate 
history, and established the foundation upon which we 
will continue to scale the business. 
As reflected in the NOAA chart below, climate solutions 
will continue to be a necessary priority to offset the 
warming trend. Half of the increase in global emissions in 
2024 was due to it being the hottest year on record. 
Overall greenhouse gas emissions from energy rose 
0.8%, and global energy demand was up 2.2%. These 
facts make it abundantly clear that our total addressable 
market, including new frontiers and technologies, will 
continue to grow. 
The HASI team is prepared to seize this opportunity as we 
expand and diversify our investments. We have the best 
team in the sector – mission-driven, savvy, creative, client-
focused, and solutions-oriented – and this talent, along 
with our access to capital, will continue to drive our 
upward spiral of success.

HASI Annual Report 2024

2024 Review and Outlook 
We had an enormously successful 2024. We established 
11 new client relationships, which contributed to our 
$2.3 billion of new sustainable infrastructure investments, 
resulting in an 11% increase in our Managed Assets and 
a corresponding 22% increase in Adjusted Net Investment 
Income. We also increased our Gain-on-Sale and fee 
income by 30%. The resulting growth in Adjusted 
Earnings per share was 10%. 
These outstanding results and our confidence in the 
business model allowed us to extend our guidance for 
Adjusted Earnings per share to grow at a compound 
annual rate of 8-10% through 2027. Extending earnings 
guidance for an additional year amidst elevated 
economic and policy uncertainty demonstrates the power 
and non-cyclical nature of our business model. 
Sustainability and Impact Leadership
In 2024, we reinforced our leadership in sustainability 
and impact by maintaining our CDP A List designation 
and receiving the highest rating of “Dark Green” from 
S&P Global Ratings for our Green Bond framework. We 
also continued to play a leadership role across key 
industry organizations and were widely recognized for 
our sustainable business model, including being named to 
TIME Magazine’s inaugural list of the World’s Best 
Companies for Sustainable Growth and Newsweek’s 
ranking of America’s Greenest Companies. Additionally, 
our policy advocacy efforts helped foster dialogue with 
government leaders and contributed to shaping policies 
that further advance the energy transition.
Diversity, Equity, and Inclusion and social justice initiatives 
have come under scrutiny recently. However, we remain 
proud of our success in these areas and continue to 
experience meaningful commercial benefits from them. 
Our diverse workforce, supported by several active 
business resource groups, ensures a wide range of 
perspectives in evaluating challenges, leading to better 
outcomes 
and 
elevated 
employee 
motivation 
and 
retention. We also remain pleased with the HASI 
Foundation and the resulting employee engagement as we 
support climate-oriented non-profits. 
Conclusion
“Resilient” is a word we frequently use to describe our 
company. One definition of resilient is “being able to 
respond to change or adversity proactively.” This is an 
excellent description of HASI. We have acted prudently 
and thoughtfully for more than 12 years as a public 
company, overcoming many challenges, including policy 
changes and interest rate volatility. None of these 
challenges have impeded our resilience, as evidenced by 
our ongoing earnings growth, no matter the obstacle. Our 
Chair, Jeff Eckel, set us on a path many years ago of 
achieving higher risk-adjusted returns from climate positive 
investing opportunities and that thesis remains unchanged. 
Despite a team of more than 150 and Managed Assets 
greater than $13 billion, we believe we are just getting 
started achieving our ultimate goals!
Thank you to our shareholders, board of directors, and 
especially our team.
Respectfully,
Jeffrey A. Lipson
Chief Executive Officer

CarbonCount® is a proprietary scoring tool for evaluating real assets to determine the efficiency by which each dollar of invested capital avoids annual carbon dioxide equivalent (CO2e) 
emissions. Estimated carbon savings are calculated using the estimated kilowatt hours (“kWh”), gallons of fuel oil, million British thermal units (“MMBtus”) of natural gas and gallons of 
water saved as appropriate, for each project. The energy savings are converted into an estimate of metric tons of CO2 equivalent emissions based upon the project’s location and the 
corresponding emissions factor data from the U.S. Government, International Energy Administration, and Locational Marginal Emissions factors. Portfolios of projects are represented on 
an aggregate basis. WaterCountTM is a scoring tool that evaluates investments in U.S.-based projects to estimate the expected water consumption reduction per $1,000 of investment. 
Estimated water savings are calculated as the sum of the direct annual estimated water savings from energy efficiency measures such as low-flow water fixtures and the annual indirect 
water savings associated with the annual kWh generated and saved by our investments. The annual kWh of electricity generated and saved by our investments are multiplied by the 
amount of water withdrawn and not returned to local water systems based upon the project’s location and the existing grid electricity generating units in that region. Indirect water savings 
is estimated using data prepared by the U.S. Government’s Energy Information Administration and the Union of Concerned Scientists.

appropriate skills and characteristics required of our 
directors in the context of the current composition of our 
board of directors, our operating requirements and the 
long-term interests of our stockholders. In accordance with 
the Guidelines, directors should possess the highest 
personal and professional ethics, integrity, and values, 
exercise good business judgment, be committed to 
representing the long-term interests of the Company and our 
stockholders and have an inquisitive and objective 
perspective, practical wisdom, and mature judgment. The 
NGCR Committee reviews director candidates with the 
objective of assembling a slate of directors that can best 
fulfill and promote our goals, taking into consideration 
personal factors and professional characteristics of each 
potential candidate, and recommends director candidates 
based upon contributions they can make to our board of 
directors and management and their ability to represent our 
long-term interests and those of our stockholders  and 
other stakeholders.
The NGCR Committee evaluates the skill sets required for 
service on our board of directors and has developed a list 
of potential director candidates. If it is determined there is 
the need for additional or replacement board members, the 
NGCR Committee will assess potential director candidates 
included on the list as well as other appropriate potential 
director candidates based upon information it receives 
regarding such potential candidates or otherwise possesses, 
which assessment may be supplemented by additional 
inquiries. In conducting this assessment, the NGCR 
Committee 
considers 
knowledge, 
experience, 
skills, 
diversity, and such other factors as it deems appropriate in 
light of our current needs and those of our board of 
directors. The NGCR Committee may seek input on director 
candidates from other directors. The NGCR Committee 
does not solicit director nominations, but it may consider 
recommendations by stockholders using the same criteria 
that it uses to evaluate other nominees. The NGCR 
Committee may, in its sole discretion, engage one or more 
search firms or other consultants, experts or professionals to 
assist 
in, 
among 
other 
things, 
identifying 
director 
candidates 
or 
gathering 
information 
regarding 
the 
background and experience of director candidates. The 
NGCR Committee will have sole authority to approve any 
fees or terms of retention relating to these services.
Our stockholders of record who comply with the advanced 
notice procedures set forth in our current Bylaws and 
outlined under the “Submission of Stockholder Proposals” 
section of this proxy statement may nominate candidates for 
election as directors. See “Submission of Stockholder 
Proposals” for information regarding providing timely notice 
of stockholder proposals under our Bylaws and the rules 
promulgated by the U.S. Securities and Exchange 
Commission (the “SEC”).
Majority Vote Policy
The Guidelines provide for a majority vote policy for the 
election of directors. Pursuant to this policy, in any 
uncontested election of directors, any nominee who receives 
a greater number of votes “withheld” from his or her 
election than votes “for” such election shall promptly tender 
his or her resignation to our board of directors following 
certification of the stockholder vote. The NGCR Committee 
shall promptly consider the resignation and make a 
recommendation to our board of directors with respect to 
the tendered resignation. In considering whether to accept 
or reject the tendered resignation, the NGCR Committee 
shall consider all factors it deems relevant, which may 
include the stated reasons, if any, why stockholders 
                                                                                                                         
withheld votes from the director, any alternatives for curing 
the underlying cause of the withheld votes, the length of 
service and qualifications of the director, the director’s past 
and expected future contributions to the Company, the 
composition of our board of directors, and such other 
information and factors as members of the NGCR 
Committee shall determine are relevant. Our board of 
directors 
will 
act 
on 
the 
NGCR 
Committee’s 
recommendation no later than 90 days after the certification 
of the stockholder vote. Any director who tenders his or her 
resignation to our board of directors will not participate in 
the NGCR Committee’s consideration or board action 
regarding whether to accept such tendered resignation.

HASI Proxy Statement 2025

We will promptly disclose our board of director’s decision 
whether to accept the resignation as tendered (providing a 
full explanation of the process by which the decision was 
reached and, if applicable, the reasons for rejecting the 
tendered resignation) in a press release, a filing with the 
SEC 
or 
in 
another 
broadly 
disseminated 
means 
of communication.
Vacancies
In accordance with our Charter and Bylaws, any vacancies 
occurring on our board of directors, including vacancies 
occurring as a result of the death, resignation, or removal of 
a director, or due to an increase in the size of our board of 
directors, may be filled only by the affirmative vote of a 
majority of the directors remaining in office, even if the 
                                                                          
remaining directors do not constitute a quorum, and any 
director elected to fill a vacancy will serve for the remainder 
of the full term of the directorship in which the vacancy 
occurred and until a successor is duly elected and qualifies.
Voting on Director Nominees
A plurality of all the votes cast on the proposal at the 
Annual Meeting at which a quorum is present is necessary 
to elect a director. Proxies solicited by our board of 
directors will be voted FOR each director nominee unless 
otherwise instructed. Because directors are elected by a 
plurality of the votes cast in the election of directors, and no 
additional nominations may be properly presented at the 
Annual Meeting, ‘withhold’ votes will have no effect on the 
election of directors. However, any director nominee who 
receives a greater number of ‘withhold’ votes from his or 
her election than ‘for’ is required to tender his or her 
                                                                                                                  
resignation as described above under “--Majority Vote 
Policy." Abstentions and broker non-votes are not votes cast 
and will have no effect on the result of the vote, although 
they will be considered present for the purpose of 
determining the presence of a quorum. If the candidacy of 
any director nominee should, for any reason, be withdrawn 
prior to the Annual Meeting, the proxies will be voted by 
the proxy holders in favor of such substituted candidates (if 
any) as shall be nominated by our board of directors. Our 
board of directors has no reason to believe that any 
nominee will be unable or unwilling to serve as a director.

Board and Corporate Governance Structure
Corporate Governance Philosophy
Our corporate governance philosophy is based on maintaining a close alignment of our interests with those of our 
stockholders. Notable features of our current corporate governance structure include the following:
Our Board of Directors
Our Charter, Bylaws and Policies
Our Stockholder Engagement
• We separated the roles of chair and chief 
executive officer.
• We have a majority vote policy for the election 
of directors.
• Our board of directors is not staggered.
• Ten of our twelve current directors are 
independent.
• We have a Lead Independent Director.
• Four directors qualify as an “audit committee 
financial experts” as defined by the SEC.
• We have established a target retirement age 
of 75 for our directors.
• The NGCR Committee oversees and directs our 
environmental, social and governance 
(“Sustainability and Impact”) strategies, 
activities, policies, and communications.
• Our stockholders have the concurrent right 
to amend our Bylaws.
• Our directors and NEOs (as defined herein) 
are required to maintain certain levels of 
stock ownership in the Company ranging 
between three and six times their base 
salary or retainer, depending on position.
• Our Statement of Corporate Policy 
Regarding Equity Transactions prohibits our 
directors and officers from hedging our 
equity securities, holding such securities in a 
margin account or pledging such securities 
as collateral for a loan.
• Our Clawback Policy provides for the 
possible recoupment of performance or 
incentive-based compensation in the event of 
an accounting restatement due to material 
noncompliance by us with any financial 
reporting requirements under the securities 
laws (other than due to a change 
in applicable accounting methods, rules 
or interpretations).
• We have an active stockholder 
outreach program, including 
annually providing our 
stockholders the opportunity to 
vote on an advisory basis on the 
compensation of NEOs.
In order to foster the highest standards of ethics and 
conduct in all business relationships, we have adopted a 
Code of Business Conduct and Ethics policy (the “Code of 
Conduct”). The Code of Conduct, which covers a wide 
range of business practices and procedures, applies to our 
officers, directors, employees, agents, representatives, and 
consultants. In addition, our whistleblowing policy (the 
                                                                              
“Whistleblower Policy”) sets forth procedures by which any 
Covered Persons (as defined in the Whistleblower Policy) 
may report, on a confidential basis, concerns relating to 
any 
questionable 
or 
unethical 
accounting, 
internal 
accounting controls or auditing matters, as well as any 
potential Code of Conduct or ethics violations. We review 
these policies on a periodic basis with our employees.

HASI Proxy Statement 2025

Our Board of Directors
Our board of directors is responsible for overseeing our 
affairs, and it conducts its business through meetings and 
actions taken by written consent in lieu of meetings. 
Pursuant to our Charter and Bylaws and the DGCL, our 
business and affairs are managed under the direction of our 
board of directors. Our board of directors has the 
responsibility for establishing broad corporate policies and 
for our overall performance and direction, but is not 
involved in our day-to-day operations, which are managed 
by our senior management team. Members of our board of 
directors keep informed of our business by participating in 
meetings of our board of directors and its committees, by 
reviewing analyses, reports and other materials provided to 
them, and through discussions with our president and chief 
executive officer and other executive officers and other 
employees of the Company.
Our board of directors intends to hold at least four regularly 
scheduled meetings per year, generally one per calendar 
quarter, and additional special meetings as necessary.
Board of Directors Leadership Structure
Our board of directors has the flexibility to decide when the 
positions of chair and chief executive officer should be held 
by one person or separated, and whether an executive or 
an independent director should be chair. This allows our 
board of directors to choose the leadership structure that it 
believes will best serve the interests of our stockholders at 
any particular time. Currently, Mr. Eckel serves as the chair, 
and Mr. Lipson serves as our chief executive officer. In 
addition, our board of directors has an active Lead 
Independent Director, Teresa M. Brenner. Our board of 
directors believes that this leadership structure is best for the 
Company and its stockholders at this time.
Our board of directors considered the actual board 
relationships and determined that there is actual and 
effective independent oversight of management by our 
supermajority independent board led by Ms. Brenner in her 
capacity as our Lead Independent Director. Ms. Brenner has 
served as our Lead Independent Director since 2019. Our 
board of directors believes that this board leadership 
structure, when combined with the functioning of the 
independent director component of our board of directors 
and our overall corporate governance structure, strikes an 
appropriate balance between strong and consistent 
leadership and independent oversight of our business 
and affairs.
ROLE OF THE LEAD INDEPENDENT DIRECTOR
TERESA M. BRENNER
• Collaborate with the chair, chief executive officer and secretary to schedule meetings of our 
board of directors and to set meeting agenda
• Ensure that matters of concern or interest to the independent directors are appropriately 
scheduled for discussion at board of directors meetings
• Chair meetings in the absence of the chair
• Organize and preside over meetings and executive sessions of the independent directors
• Serve as the principal liaison between the independent directors and the chair or chief 
executive officer on matters where either person may be conflicted
• Together with the full board of directors, evaluate the performances of the chief executive 
officer and chair and meet with each of the chief executive officer and chair to discuss 
such evaluations
• Authorize the retention of outside advisors and consultants who report directly to our board 
of directors
• Meet regularly with the chair as well as each director
• Along with management, periodically meet with institutional and other investors

Director Independence, Executive Sessions, and Independent Oversight
The Guidelines provide that a majority of the directors 
serving on our board of directors must be independent as 
required by NYSE listing standards. In addition, as 
permitted under the DGCL, our board of directors has 
adopted 
certain 
independence 
standards 
(the 
“Independence 
Standards”) 
to 
assist 
it 
in 
making 
determinations with respect to the independence of 
directors. The Independence Standards are available for 
viewing on our website at www.hasi.com. Based upon its 
review of all relevant facts and circumstances, our board of 
directors has affirmatively determined that ten of our twelve 
current directors—Lizabeth Ardisana, Clarence Armbrister, 
Teresa Brenner, Nancy Floyd, Charles O’Neil, Richard 
Osborne, Steven Osgood, Kimberly Reed, Laura Schulte 
and Barry Welch —qualify as independent directors under 
the NYSE listing standards and the Independence 
Standards. 
There is no familial relationship, as defined under the SEC 
regulations, 
among 
any 
of 
our 
directors 
or 
executive officers.
The independent directors serving on our board of directors 
meet in executive sessions at least four times per year at 
regularly scheduled meetings of our board of directors and 
are active in the oversight of the Company. These executive 
sessions of our board of directors are presided over by our 
Lead Independent Director, Ms. Brenner. The independent 
directors oversee such critical matters as the integrity of our 
financial statements, the evaluation and compensation of 
executive officers and the selection and evaluation of 
directors. Each independent director has the ability to add 
items to the agenda of our board of directors meetings or 
raise subjects for discussion that are not on the agenda for 
that meeting.

Independence
Our board of directors has determined that all of the members of the Audit Committee are independent as 
required by the NYSE listing standards, SEC rules governing the qualifications of Audit Committee members, 
the Guidelines, the Independence Standards and the written charter of the Audit Committee.
Financial Expertise and Literacy
Our board of directors has also determined, based upon its qualitative assessment of their relevant levels of 
knowledge and business experience, that Mr. Osgood, Ms. Floyd and Mr. Osborne each qualify as an 
“audit committee financial expert” for purposes of, and as defined by, the SEC rules and each has the 
requisite accounting or related financial management expertise required by NYSE listing standards. In 
addition, our board of directors has determined that all of the members of the Audit Committee are

Since 2018, the Compensation Committee has engaged Pay Governance LLC (“Pay Governance”), a

targets for our NEOs. In July 2019, the Compensation Committee also engaged Pay Governance to provide 
analysis and recommendations regarding (1) base salaries, annual bonuses and long-term incentive 
compensation for our executive management team, and (2) the director compensation program for 
non-employee members of our board of directors. Pay Governance reports directly to the Compensation 
Committee and the Compensation Committee has determined that Pay Governance is independent pursuant 
to the Compensation Committee charter.
Compensation Committee Interlocks and Insider Participation
The Compensation Committee is comprised solely of independent directors. No member of the 
Compensation Committee is a current or former officer or employee of ours or any of our subsidiaries. Other

Cybersecurity
We recognize how critical cybersecurity and cyber 
resilience are to the well-being of our organization, our 
business stakeholders, and the information we rely on to 
profitably operate. In response to the dynamic global cyber 
risk environment, our chief technology officer oversees the 
adaptation of cybersecurity and training programs, guided 
by the Finance and Risk Committee of our board 
of directors.
Identifying and addressing these cyber threats while 
upholding our principles of governance, internal controls, 
and transparency is a priority for our cybersecurity 
program. 
The 
Finance 
and 
Risk 
Committee 
and 
management 
collectively 
provide 
oversight 
of 
our 
information technology and cybersecurity program, which is 
led by our chief technology officer and supported by a 
skilled 
and 
high-performing 
team 
of 
technology professionals.
Our focused cyber and information security strategy draws 
from operationally pragmatic components of the National 
Institute of Standards and Technology (NIST) Cybersecurity 
Common Standards Framework, Center for Internet Security 
(CIS) benchmarks as well as the Information Technology 
Infrastructure Library (ITIL).
Our cybersecurity infrastructure includes a combination of 
premier information technology services supported by 
proven vendors whose services address the range of risks 
identified by the Finance and Risk Committee of our board 
of directors, internal risk management team and internal 
cybersecurity team.
Annual Board of Directors and Committee Assessments
Our board of directors and each of its committees conducts 
an annual self-assessment process, implemented and 
overseen by the NGCR Committee, in order to review the 
effectiveness of our board of directors and its committees. 
The formal self-evaluation may be in the form of written or 
oral questionnaires and may be administered by board 
members 
and/or 
by 
third 
parties, 
as 
determined 
appropriate by the NGCR Committee for the related 
performance cycle. Director feedback is solicited at both the 
board and committee levels. The results of our board of 
directors and committee self-assessments are compiled and 
              
presented to our board of directors, and items identified in 
the self-assessments requiring follow-up are monitored on an 
ongoing basis by our board of directors and by 
management. In addition to the formal annual board and 
committee evaluation process, our Lead Independent 
Director speaks with each board member at least quarterly, 
and receives input regarding board and committee 
practices and management oversight. Throughout the year, 
committee members also have the opportunity to provide 
input directly to committee chairs or to management.

address significant issues of corporate governance and set 
forth procedures by which our board of directors carries out 
its  responsibilities. Among the areas addressed by the 
Guidelines are the composition of our board of directors, 
its  functions and responsibilities, its standing committees, 
director qualification standards, access to management and 
independent advisors, director compensation, management 
succession, director orientation and continuing education 
and the annual performance evaluation and review of our 
board of directors and committees. The Guidelines are 
available for viewing on our website at www.hasi.com. We 
will also provide the Guidelines, free of charge, to 
stockholders who request it. Requests should be directed to 
Steven L. Chuslo, our executive vice president, chief legal 
officer and secretary, at HA Sustainable Infrastructure 
Capital, Inc., 1 Park Place, Suite 200, Annapolis, 
Maryland 21401.
Whistleblower Policy
Our Whistleblower Policy sets forth procedures by which 
any Covered Persons (as defined in the Whistleblower 
Policy) may report, on a confidential basis, concerns 
relating to any questionable or unethical accounting, 
internal accounting controls or auditing matters, as well as 
any potential Code of Conduct or ethics violations. We 
maintain a confidential hotline for reporting potential 
violations. All reports will be taken seriously. We will fully 
investigate each allegation and, when appropriate, take 
appropriate action. Reports are sent solely to the chair of 
the Audit Committee, the chair of the NGCR Committee and 
the chief legal officer (unless such person is the subject of 
the applicable report). Since our IPO in 2013, we have 
never received any whistleblower reports.
Personal Loans to Executive Officers and Directors
In compliance with, and consistent with our commitment to 
operate in a manner consistent with, applicable law, we 
prohibit extensions of credit in the form of personal loans to 
or for the benefit of our directors and executive officers.
Corporate Governance Review
In overseeing our corporate policies and our overall 
performance and direction, our board of directors has 
adopted the approach of operating in what it believes are 
the long-term best interests of the Company and our 
stockholders. In operating under these principles, our board 
of directors continuously reviews our corporate governance 
structure 
and 
considers 
whether 
any 
changes 
are 
necessary or desirable.

HASI Proxy Statement 2025

Active Stockholder Outreach
We believe that engaging with investors is fundamental to 
our commitment to good governance and essential to 
maintaining our industry-leading practices. Throughout the 
year, we seek opportunities to connect with our investors to 
gain and share valuable insights into current and emerging 
business and governance trends.
In 2024, we hosted over 250 meetings with more than 120 
existing and prospective investors.
Topics discussed include our investment criteria, interest rate 
and other risk management practices, political and 
regulatory matters and our focus on sustainability and 
strong 
governance 
practices. 
These 
meetings 
were 
conducted 
in 
person, 
via 
teleconference, 
via 
videoconference or one-on-one at industry conferences. Our 
engagement activities take place throughout the year, and 
we also conduct quarterly earnings calls where we try to 
answer many of the new questions that we receive during 
our investor outreach.
Management Succession Planning
Our board of directors recognizes that management 
succession planning is a fundamental and ongoing part of 
its responsibilities. The NGCR Committee has utilized a 
framework relating to executive succession planning under 
which the NGCR Committee has defined specific criteria 
for, and responsibilities of, each of the executive officer 
roles of the Company. The NGCR Committee then focuses 
on the skill set needed to succeed in these roles both on a 
long-term and an emergency basis. Our Lead Independent 
Director also meets on this topic separately with our chief 
executive officer and facilitates additional discussions with 
our independent directors about executive succession 
planning throughout the year, including at executive 
sessions. Succession planning remains a priority for the 
NGCR Committee, which has worked with Mr. Lipson to 
ensure an appropriate emergency succession protocol and 
to develop our long-term succession plan.
Communications with our Board of Directors
Our board of directors has approved a process to enable 
communications with the independent directors on our 
board of directors or the chair of any of the committees of 
our board of directors. Communications by email should be 
sent to legaldepartment@hasi.com. Communications by 
regular 
mail 
should 
be 
sent 
to 
the 
attention 
of 
Steven  L.  Chuslo, our executive vice president, chief legal 
officer and secretary, at our office at 1  Park Place, Suite 
200, Annapolis, MD 21401. Each communication received 
will be reviewed to determine whether the communication 
requires immediate action. All appropriate communications 
received, or a summary of such communications, will be 
sent to the appropriate member(s) of our board of directors. 
However, we reserve the right to disregard any 
communication we determine is unduly hostile, threatening, 
illegal, does not reasonably relate to us or our business, or
is similarly inappropriate. Our secretary, or his or her 
delegate, has the authority to disregard any inappropriate 
communications or to take other appropriate actions with 
respect to any such inappropriate communications.
In addition, any of our stockholders and any other person 
may make a good faith report to the Audit Committee 
regarding any questionable or unethical accounting or 
auditing matters via regular mail addressed to the Audit 
Committee, 
1 
Park 
Place, 
Suite 
200, 
Annapolis,

In addition, any of our stockholders and any other person 
may make a good faith report to our Lead Independent 
Director regarding any concerns via regular mail addressed 
to our Lead Independent Director, 1 Park Place, Suite 200,

Climate Leadership
We own and invest in a diversified portfolio of climate 
solutions projects focused on reducing or mitigating the 
impacts of climate change. Under the direction of our chief 
executive officer and our board of directors, we are focused 
on achieving a high level of environmental and social 
responsibility and strong corporate governance. The NGCR 
Committee is responsible for our oversight of sustainability, 
impact, and governance matters, including related policies 
and communications. Additionally, we have a committee of 
employees from across our organization that is focused on 
implementing sustainability and impact strategies and 
policies and reports directly to our chief executive officer. 
We publish an annual Sustainability & Impact Report that 
illustrates our progress on these matters.
Our business and business strategy are focused on 
addressing climate change, in part through the reduction of 
carbon emissions that have been scientifically linked to 
climate change. As described under “--Investment Strategy,” 
we quantify the carbon impact of each of our investments. 
In addition, we operate our business in a manner intended 
to reduce our own environmental impact, including by 
purchasing Renewable Energy Credits (RECs) to address the 
impact of our office operations, encouraging recycling and 
composting, and offering clean transportation employee 
incentives for electric and hybrid vehicles. We have also 
adopted policies focused on minimizing the environmental 
impact of our operations.
Investment Strategy
Our vision is that every investment should improve our climate future, which is why we require that all prospective 
investments be neutral-to-negative on incremental carbon emissions or have some other tangible environmental benefit, such 
as reducing water consumption.
Based on decades of investment experience across interest rate environments, throughout intermittent policy support for 
reducing carbon emissions, and several “boom and bust” cycles in clean energy markets, we have created a climate 
positive investment thesis based on the following tenets:
1)
More efficient technologies are more productive and 
thus should lead to higher economic returns.
2)
Lower risk is inherent in a portfolio of diverse 
investments, 
generated 
by 
trends 
of 
increasing 
decentralization and digitalization of energy assets, 
compared to a portfolio comprised solely of centralized 
utility-scale investments.
3)
Investing in assets aligned with scientific consensus and 
universal social values will reduce potential regulatory 
and 
social 
costs 
through 
better 
internalization 
of externalities.
4)
Assets that reduce carbon emissions represent an 
embedded option that may increase in value if 
regulations were to set a price on carbon emissions.

Green Debt Leadership
Overview
At HASI, we are committed to ensuring all debt we issue is dedicated to eligible green projects. Typically, for corporate 
unsecured debt, we pursue independent verification. Since 2013, we have raised approximately $13.4 billion of green 
debt (including off-balance sheet securitizations), spanning corporate and non-recourse issuances to securitizations. In 2024, 
we issued more than $2.6 billion in green CarbonCount-based debt.
The HASI Green Bond Framework sets out the guidelines for our green financing issuances in accordance with the Green 
Bond Principles (2021) and Green Loan Principles (2023) to inform our best-efforts alignment to the EU Taxonomy. In 2024, 
we obtained a Second-Party Opinion on our Green Bond Framework to ensure alignment with the 2021 Green Bond and 
Green Loan Principles, receiving the highest tier alignment assessment of Dark Green from S&P Global Ratings. This rating 
means that S&P has reviewed and verified HASI’s commitment to allocate the net proceeds issued under our 
publicly-available Green Bond Framework exclusively to new or existing eligible green projects.

Our People 
Placing emphasis on an engaged, collaborative and fairly 
compensated staff, is an important factor in our financial 
success. Our culture is focused on hiring and retaining 
highly talented employees with diverse perspectives and 
empowering them to create value for our stockholders, and 
our success is dependent on employee understanding of, 
and investment in, their role in that value creation. Our 
employees are responsible for upholding our mission, 
purpose, and values.
Engaging with Our Team
Our employees are typically engaged in our mission of 
sustainability and we believe engagement improves their 
performance, as well as our employee recruitment and 
retention. Our chief executive officer periodically leads 
employee meetings intended to reinforce the importance of 
our mission and regularly meets with small groups of 
employees to receive their feedback on our business. We 
also meet no less than quarterly as a Company to provide 
information to employees on our mission, strategic planning 
and financial results. We continuously evaluate our 
employees’ level of engagement through meetings or calls 
that include asking open-ended questions, and through 
formal surveys or similar tools administered on a periodic 
basis. To improve retention and business continuity, We 
have also instituted human capital development programs. 
These formal programs include HASI U, an online learning 
platform to enhance employees' technical and soft skills, as 
well as an employee mentorship program, which fosters 
knowledge 
transfer, 
leadership 
development, 
and 
succession planning.
Our recognition of the importance of diversity, equity, and 
inclusion is an important aspect of our human capital 
approach. We are more than just the sum of individual 
roles, skills, and productivity. We are also a team that 
values the mutually reinforcing empowerment of all people 
regardless of race, culture, identity, gender expression, 
sexual orientation, political affiliation and learning and 
engagement styles. By opening ourselves to the broadest 
range of talent, we improve both our company performance 
and our ability to attract and retain talent. Our 
comprehensive, performance- and values-driven approach 
comprises initiatives intended to foster an innovative, 
creative culture of belonging.
Goals and Metrics
Tracking 
internal 
talent 
metrics 
including 
workforce 
demographics, critical role pipeline and diversity data, and 
engagement and inclusion indices informs our collective 
decision-making with diverse perspectives. Our human 
resources team manages and reports these metrics to our 
executive officers and our board of directors on a quarterly 
basis.
Because transition planning is a foremost consideration in 
our recruiting strategy, identifying and developing our next 
generation of leaders means onboarding the most qualified 
individuals from the diverse talent pool we actively recruit. 
We remain focused on recruiting and promoting highly 
qualified personnel from all demographics, including 
women, people of color and other recognized groups, for 
management and Board positions. 
Our commitment to diversity is a continuous effort that 
requires supporting our diverse population of employees in 
their onboarding, training, development, and progression 
within the Company.
Currently, our board of directors is 40% female and 20% 
racial or ethnic minority. We recognize the need to 
maintain diversity across our organization and continue to 
keep 
qualified 
personnel 
top 
of 
mind 
as 
our 
needs mandate.

Health and Well-Being
Because our people create the long-term success of our 
business, we endeavor to support the health and well-being 
of our full-time employees and their families with total 
rewards that address the varied needs of our growing 
workforce. Our organizational mission and our track record 
of success drives our attraction and recruitment of top talent.
Our remuneration policies ensure that our team members 
are fairly compensated. We also reward elite performance 
in multiple ways. Beyond the competitive base salaries and 
cash bonuses we offer, employees also generally receive a 
portion of their compensation in the form of equity grants. 
Each employee in good standing who remains with the 
Company for at least one year becomes a stockholder 
whose interest in the prosperity of our organization further 
distinguishes our compensation packages and employee 
retention efforts.
For all full-time employees, attractive non-salary benefits 
supplement the compelling career opportunities we offer. 
We continuously evaluate the competitiveness of our 
benefits offerings to meet the varying needs of our 
employees and their families. We continue to pay almost all 
employee healthcare insurance costs. Further, in addition to 
what we believe to be market total rewards benefits, we 
provide additional benefits, such as employee assistance 
programs, back-up childcare solutions, and a tuition 
reimbursement 
program. 
We 
also 
recognize 
that 
accommodating the varied needs of all employees 
maintains morale and improves retention, and accordingly 
offer benefits that are reflective of our inclusive culture and 
our team’s needs.

Skills for the Future
We adhere to a blended learning approach with the 
understanding that our people learn from experiences (on 
the job and outside of work), from other people (mentors or 
supportive managers), and from formal learning and 
training programs. We run a periodic education series that 
includes internal and external speakers presenting topics of 
interest that are relevant to our employees. We provide 
multiple learning solutions that cover a wide range of areas 
such as leadership skills, financial knowledge, technology 
training, presentation skills, and training. We also support 
the pursuit of advanced certifications and degrees in areas 
including business, science and engineering, and liberal 
and fine arts and employ formal and informal coaching 
arrangements. 
We care about our employees’ employment experience and 
recognize them as individuals who are motivated in 
different ways. Managers hold performance conversations 
with their employees on a periodic basis to ensure that 
employees receive adequate performance feedback , and 
to allow managers to both obtain insight into how to 
support the development of their staff and to ensure that 
performance expectations are clear and aligned with the 
Company’s overarching objectives. We also facilitate 
continuous dialogue between these formal touchpoints.

proactively seek team member input on how we can 
enhance our work environment and implement feedback on 
how we can positively influence our local communities.

Compensation of Independent Directors 
Annual Compensation
We have approved and implemented a compensation 
program for our non-executive directors that consists of an 
annual cash retainer fee and long-term equity awards as 
described below. We pay directors’ fees to those directors 
who are independent under the NYSE listing standards, as 
more fully described in the section under “Board and 
Corporate 
Governance 
Structure—Our 
Board 
of 
Directors—Director Independence, Executive Sessions and 
Independent Oversight.” Starting March 1, 2025 and 
following his transition from executive chair upon the end of 
the term of his employment agreement with the Company, 
we also pay director fees to Mr. Eckel.
The components of the independent director compensation 
for 2024 were as follows:
• cash retainer of $110,000 annually per director;
• incremental cash retainer to our Lead Independent 
Director of $35,000 annually;
• incremental cash retainer to each of the Chairs of the 
Audit Committee and Compensation Committee of 
$25,000 annually;
• incremental cash retainer to each of the Chairs of the 
NGCR Committee and the Finance and Risk Committee of 
$15,000 annually; and
• equity grant of $145,000 annually per director, which to 
date has been in the form of LTIP units (as defined below). 
LTIP units are described in more detail as set forth below 
under 
“Executive 
Compensation—Compensation 
Discussion and Analysis.”
All cash fees described above are paid quarterly in arrears. 
Our board of directors permitted directors to make an 
election, on or before December 31, 2023, to receive 
equity in lieu of all or a portion of their cash compensation 
for 2024.
A director who is also an employee of the Company is 
referred to as an executive director. Executive directors do 
not receive compensation for serving on our board 
of directors.
Other Compensation
We reimburse each of our independent directors for their respective expenses incurred in connection with their respective 
board responsibilities. Independent directors are not eligible to participate in any of the savings or retirement programs for 
our employees. Other than as described in this section, there are no separate benefit plans for directors.
Stock Ownership Guidelines for Non-Employee Directors
Under our stock ownership guidelines, each non-employee 
director must hold an ownership stake in the Company of at 
least five times the annual cash retainer. Each non-
employee director has five years to comply from the later of 
the date they become covered under this policy or the date 
the policy was originally adopted. Until the individual is in 
compliance, non-employee directors must retain 100% of 
any equity grants, net of any shares withheld or sold to 
satisfy taxes. Stock ownership for the purpose of our stock 
ownership guidelines includes stock, restricted stock, OP 
units (as defined below) and unvested OP units held by the 
covered individual but excludes any RSUs (as defined 
below). As of April 7, 2025, each of our directors, other 
than Mses. Ardisana, Floyd, Reed and Schulte and 
Messrs.  Armbrister and Welch had met the ownership 
thresholds under the stock ownership guidelines. Each of 
Mr. Armbrister and Ms. Floyd have until 2026 to meet these 
thresholds. Ms.  Ardisana has until 2027 to meet these 
thresholds, 
Ms. 
Reed 
has 
until 
2028 
to 
meet 
these thresholds, and each of Ms. Schulte and Mr. Welch 
has until 2030 to meet these thresholds. Because 
Ms. Schulte and Mr. Welch joined our board of directors 
effective April 15, 2025, they had not received director 
grants as of the Record Date.
Our chief executive officer, who also serves as a member of 
our board of directors, is also subject to stock ownership 
guidelines, which are described in more detail as set forth 
below under “Executive Compensation—Compensation 
Discussion and Analysis—Stock Ownership Guidelines for 
Named Executive Officers.”

HASI Proxy Statement 2025

Changes to Our Director Compensation for 2025
For 2025, our board of directors will pay the chair of our board of directors an incremental cash retainer of $100,000 and 
will increase the incremental cash retainer for services as Lead Independent Director from $30,000 to $35,000. No further 
changes were made to the cash retainers or targeted annual equity grants. Consistent with prior years, our board of 
directors permitted directors to make an election, on or before December 31, 2024, to receive equity in lieu of all or a 
portion of their cash compensation for 2025.
Compensation Committee Review
The Compensation Committee reviews and makes recommendations to our board of directors annually with respect to the 
compensation of our independent directors. In setting director compensation, our board of directors generally considers the 
compensation practices and levels for directors paid by our peer group, as well as the expected time commitment from the 
independent directors in such year.

Proposal No. 2
Ratification of Appointment of Independent 
Registered Public Accounting Firm
The Audit Committee has appointed Ernst & Young LLP as 
our independent registered public accounting firm for the 
fiscal year ending December 31, 2025. Our board of 
directors is requesting that our stockholders ratify this 
appointment of Ernst & Young LLP.
Ernst & Young LLP has audited our or our predecessor’s 
consolidated financial statements since 1983 and has also 
provided certain tax and other services to us.
Neither our Bylaws nor other governing documents or law 
require stockholder ratification of the Audit Committee’s 
appointment of Ernst & Young LLP as our independent 
registered public accounting firm. However, our board of 
directors is submitting the appointment of Ernst & Young LLP 
to the stockholders for ratification as a matter of good 
corporate practice. In the event that ratification of this 
appointment of independent registered public accounting 
firm is not approved at the Annual Meeting, the Audit 
Committee will review its future selection of our independent 
registered public accounting firm. Even if the selection is 
ratified, the Audit Committee, in its discretion, may direct 
the appointment of a different independent registered public 
accounting firm at any time during the year if it determines 
that such a change would be in our best interests.
Representatives of Ernst & Young LLP are expected to attend 
the Annual Meeting virtually via webcast, will have the 
opportunity to make a statement if they desire to do so and 
will be available to respond to appropriate inquiries 
from stockholders.

Required Vote
A majority of all of the votes cast on this proposal at the 
Annual Meeting at which a quorum is present is required 
for its approval. Proxies solicited by our board of directors 
will be voted FOR this proposal, unless otherwise instructed. 
Abstentions are not votes cast and will have no effect on the 
result of the vote, although they will be considered present 
for the purpose of determining the presence of a quorum.
Our board of directors recommends a vote FOR  the 
ratification of the appointment of Ernst & Young LLP as 
our independent registered public accounting firm for 
our fiscal year ending December 31, 2025.
Report of the Audit Committee
The Audit Committee has furnished the following report for 
the fiscal year ended December 31, 2024:
The Audit Committee is responsible for monitoring the 
integrity of our consolidated financial statements, our system 
of internal controls, our risk management, the qualifications, 
independence and performance of our independent 
registered public accounting firm and our compliance with 
related legal and regulatory requirements. The Audit 
Committee has the sole authority and responsibility to 
select, determine the compensation of, evaluate and, when 
appropriate, replace our independent registered public 
accounting firm. The Audit Committee operates under a 
written charter adopted by our board of directors.
Management is primarily responsible for our financial 
reporting process including the system of internal controls 
and for the preparation of consolidated financial statements 
in accordance with accounting principles generally 
accepted in the United States. Ernst & Young LLP, our 
independent 
registered 
public 
accounting 
firm, 
is 
responsible for performing an independent audit of our 
annual consolidated financial statements and expressing an 
opinion as to their conformity with accounting principles 
generally accepted in the United States and on the 
effectiveness of the Company’s internal controls over 
financial reporting based on criteria established in 2013 by 
the Committee of Sponsoring Organizations of the 
Treadway 
Commission. 
The 
Audit 
Committee’s 
responsibility is to oversee and review the financial 
reporting process. The Audit Committee is not, however, 
professionally engaged in the practice of accounting or 
auditing and does not provide any expert or other special 
assurance as to such financial statements concerning 
compliance with laws, regulations or accounting principles 
generally accepted in the United States or as to auditor 
independence. 
The 
Audit 
Committee 
relies, 
without 
independent verification, on the information provided to it 
and on the representations made by our management and 
our independent registered public accounting firm.
Representatives of Ernst & Young LLP attended the Audit 
Committee meetings on at least a quarterly basis. These 
meetings were designed, among other things, to facilitate 
and 
encourage 
communication 
among 
the 
Audit 
Committee, management and Ernst & Young LLP. The Audit 
Committee reviewed and discussed the Company’s audited 
financial statements with management and Ernst & Young 
LLP. The Audit Committee also discussed with Ernst & Young 
LLP matters that independent accounting firms must discuss 
with audit committees under generally accepted auditing 
standards and standards of the Public Company Accounting 
Oversight Board (the “PCAOB”). The Audit Committee met 
with Ernst & Young LLP, with and without management 
present, to discuss the results of their audit.
PROPOSAL NO. 2 RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
REQUIRED VOTE
HASI Proxy Statement 2025
35

The Audit Committee also discussed with Ernst & Young LLP 
their independence from the Company. Ernst & Young LLP 
provided to the Audit Committee the written disclosures and 
the letter required by applicable requirements of the 
PCAOB 
regarding 
the 
independent 
accountant’s 
communication 
with 
audit 
committees 
concerning 
independence and represented that it is independent from 
us. The Audit Committee also received regular updates on 
the amount of fees and scope of audit, audit-related, tax 
and all other services provided by Ernst & Young LLP.
Based on the Audit Committee’s review and these meetings, 
discussions and reports, and subject to the limitations on the 
Audit Committee’s role and responsibilities referred to 
above and in its written charter, the Audit Committee 
recommended to our board of directors that our audited 
consolidated financial statements for the fiscal year ended 
December 31, 2024 be included in our Form 10-K filed 
with the SEC. The Audit Committee has also appointed Ernst 
& Young LLP as our independent registered public 
accounting 
firm 
for 
the 
fiscal 
year 
ending 
December 31, 2025 and is presenting this selection to our 
stockholders for ratification.

Proposal No. 3
Stockholder Advisory (Non-binding) Vote to 
Approve Our Executive Compensation
The Dodd-Frank Wall Street Reform and Consumer 
Protection Act enacted in July 2010 includes a provision, 
which is further required by Section 14A of the Exchange 
Act, commonly referred to as “Say on Pay,” that entitles our 
stockholders to cast an advisory (non-binding) vote to 
approve the resolution approving the compensation of each 
of our named executive officers (each, a “Named Executive 
Officer” or “NEO”) as disclosed in this proxy statement. At 
the 2023 annual meeting of stockholders, our stockholders 
voted for a one-year interval for the advisory vote on 
executive compensation.
We believe that our compensation policies and practices 
are strongly aligned with the long-term interests of our 
stockholders. Stockholders are urged to read the “Executive 
Compensation” section of this proxy statement, and 
especially the Compensation Discussion and Analysis, 
which discusses our compensation philosophy and how our 
compensation 
policies 
and 
practices 
implement 
our philosophy.
As 
described 
more 
fully 
in 
that 
discussion, 
our 
compensation programs are designed to achieve the 
following objectives:
• aligning 
our 
management 
team’s 
interests 
with 
stockholders’ 
expectations, 
including 
our 
continued 
investment in solutions that reduce carbon emissions or 
increase resilience to climate change;
• motivating and rewarding our management team to grow 
our assets and earnings in a manner that is consistent with 
appropriate risk-taking and based on sound corporate 
governance practices; and
• attracting and retaining an experienced, diverse and 
effective management team while also maintaining an 
appropriate expense structure.

Overview of 2024 Performance and Our Pay for 
Performance Philosophy
One of the guiding principles underlying the Compensation 
Committee’s executive compensation philosophy is that 
compensation should encourage and reward strong 
financial and operational performance. Our executive 
compensation philosophy is also implicitly linked to 
Sustainability and Impact performance, as our financial 
performance is driven in large part from investments that 
address climate change – either through quantified 
projected reductions in carbon emissions or other 
environmental benefits. In furtherance of this philosophy, the 
Compensation Committee structured the 2024 annual 
incentive plan with quantitative and qualitative performance 
goals based upon the Company’s strategic goals. The 
quantitative goals were intended to focus our NEOs on the 
key financial metrics that impact the Company’s results and 
stockholder value, including Adjusted Earnings (as defined 
below)  and Adjusted Return on Equity (“ROE”). The 
qualitative goals included an evaluation of overall 
performance of each NEO. Set forth below is a graphical 
illustration of our GAAP Earnings per share (“EPS”), 
GAAP-based ROE, Adjusted EPS and Adjusted ROE.

(1)
Adjusted EPS is not a financial measure calculated in accordance with GAAP. A reconciliation of 2024 Adjusted Earnings to GAAP net income is located on page 51 of our Form 10-K 
for the year ended December 31, 2024. We refer to this metric as “Adjusted Earnings.” In accordance with our investment policy, we will only invest in assets that are negative on 
incremental carbon emissions or have some other tangible environmental benefit such as reducing water consumption. As a result, our Adjusted Earnings and other performance metrics 
that are based on Adjusted Earnings are linked to the positive contributions we make to the environment. We believe that Adjusted Earnings has been a meaningful indicator of our 
economic performance and is useful to our investors as well as management in evaluating our performance as it relates to expected dividend payments over time. Additionally, we believe 
that our investors also use Adjusted Earnings, or a comparable supplemental performance measure, to evaluate and compare our performance to that of our peers, and as such, we 
believe that the Adjusted Earnings metric is useful to our investors.
(2)
Adjusted ROE is not a financial measure calculated in accordance with GAAP. It is calculated as annual Adjusted Earnings as described above divided by the average of our GAAP 
stockholders’ equity as of the last day of the four quarters during the year. GAAP stockholders’ equity as of December 31, 2024 and December 31, 2023, are located on page 68 of our 
Form 10-K for the year ended December 31, 2024. GAAP stockholders’ equity as of December 31, 2022 and December 31, 2021, are located on page 81 of our Form 10-K for the 
year ended December 31, 2022.  GAAP stockholders’ equity as of December 31, 2020 is located on page 85 of our Form 10-K for the year ended December 31, 2020. GAAP 
stockholders’ equity as of March 31, June 30, and September 30 for all years presented above are located on page 1 of the respective quarter’s Form 10-Q. We refer to this metric as 
“Adjusted ROE.”

OVERVIEW OF 2024 PERFORMANCE AND OUR PAY FOR PERFORMANCE PHILOSOPHY
38
HASI Proxy Statement 2025

In addition, during 2024, we achieved the following 
milestones that we believe position us for future success:
• Delivered $2.45 Adjusted EPS on a fully diluted basis in 
2024, compared to $2.23 Adjusted EPS in 2023, 
representing 10% year-on-year growth. GAAP EPS on a 
fully diluted basis in 2024 was $1.62, and in 2023 
was $1.42.
• Grew our portfolio 6% in 2024 to $6.6 billion and 
Managed Assets 11% to $13.7 billion as of the end 
of 2024.
• Reported GAAP-based Net Investment Income (“NII”) of 
$24 million in 2024, compared to $58 million in 2023.
• Increased Adjusted NII2 in 2024 by 22% year-on-year to 
$264 million, compared to $217 million in 2023.
• Closed $2.3 billion of investments in 2024, compared to 
$2.3 billion in 2023.
• Reported pipeline of greater than $5.5 billion as of the 
end of 2024, compared to greater than $5.0 billion as of 
the end of 2023.
• Increased dividend to $0.42 per share for the first quarter 
of 2025, representing a 1% increase over the dividend 
declared in the fourth quarter of 2024.
• Estimated more than 856,000 metric tons of carbon 
emissions will be avoided annually by our transactions 
closed in 2024, equating to a CarbonCount®  score of 
0.38 metric tons per $1,000 invested.
Higher recurring GAAP-based and Adjusted NII due to 
significant origination volumes, including growth in FTN 
market, and continued strength in gain-on-sale and other fee 
income contributed to another successful year. The 
Company demonstrated resiliency by further diversifying 
funding sources, portfolio of investments with improving 
asset yields and maintaining liquidity in a challenging 
market environment. As a result, Adjusted EPS and Adjusted 
ROE exceeded our predetermined target, which entitled the 
NEOs to receive 200% of their target corporate 
performance bonus amounts, which was 90% of NEO 
incentive compensation. It was also determined, based on 
Compensation Committee evaluation after input from the 
CEO, that the NEOs had performed at or above expected 
levels on their individual performance measures, which 
comprised the remaining 10% of such NEO incentive 
compensation. The calculated corporate performance 
combined with individual performance resulted in the NEOs 
receiving an average of 190% of their target incentive 
compensation, an increase from approximately 153% 
from 2023.
Overall, we believe these 2024 results provide us a solid 
foundation to achieve longer-term future success. Our 
compensation decisions for 2024  have considered the 
challenges faced and results achieved by our management 
team in 2024. Our 2024 results would not have been 
achieved without the leadership and efforts of the NEOs, 
and the results had a direct impact on the compensation 
decisions. When it made its decisions about compensation 
to be paid in 2025 for 2024 performance, the 
Compensation Committee recognized the 2024 results and 
achievements noted above, the performance of the 
Company and the NEOs, the performance of the Company 
as compared to other companies in our peer group and the 
contributions and accomplishments of our NEOs to our 
continuing 
profitability.

Executive Compensation
Compensation Discussion and Analysis
This Compensation Discussion and Analysis (“CD&A”) 
describes the executive compensation program that was in 
place for 2024 for our NEOs, which include our “chief 
executive officer” or “CEO,” our “CFO,” and our next three 
most highly compensated executive officers. 
This CD&A explains the overall objectives, elements and 
policies underlying our NEO compensation program for 
2024. In general, our 2024 compensation consisted of a 
base salary, an annual bonus paid in cash and stock 
awards that were granted based on our 2024 performance 
and the 2024 long-term equity incentive program. We also 
provide some forward-looking detail about our current 
NEOs’ 2025 base salaries that were adjusted to be 
effective March 2025 and annual bonus opportunities to be 
paid (if earned) in cash and/or stock based on our 2025 
performance.  This  discussion contains forward-looking 
statements 
that 
are 
based 
on 
our 
current 
plans, 
considerations,  expectations  and determinations regarding 
future compensation programs.
Executive Summary
We are an investor in sustainable infrastructure assets 
advancing the energy transition. Our investments are 
diversified across multiple asset classes, including utility-
scale solar, onshore wind, and storage, distributed solar 
and storage, RNG, and energy efficiency. We combine 
deep expertise in energy markets and financial structuring 
with long-standing programmatic client partnerships to 
deliver superior risk-adjusted returns and measurable 
environmental benefits. 
We are internally managed by an executive leadership 
team that has extensive relevant industry knowledge and 
experience, and a team of over 150 investment, operating, 
and technical professionals. We have long-standing, 
programmatic relationships with some of the leading U.S. 
clean energy project developers, owners and operators, 
utilities, and energy service companies, which provide 
recurring investment and fee-generating opportunities, while 
also 
enabling 
scale 
benefits 
and 
operational 
and 
transactional efficiencies. Partnering with these clients, we 
are able to earn attractive risk-adjusted returns by investing 
in a variety of asset classes across our three primary climate 
solutions markets: behind-the-meter, grid-connected, and 
fuel, transport, and nature.
Our primary objective is to earn attractive risk-adjusted 
returns that sufficiently exceed our cost of capital. We 
believe we are able to generate superior risk-adjusted 
returns in part due to our adherence to a core set of 
investment criteria. One of the defining criteria of our 
investment strategy is that all of our investments must be 
neutral to negative on incremental carbon emissions or have 
some other tangible environmental benefit such as reducing 
water consumption or increasing resilience to extreme 
weather events. In addition, we are focused primarily on 
investments which are (a) income-generating sustainable 
infrastructure assets, (b) supported by underlying, long-term 
recurring cash flows, (c) contracted with creditworthy, 
incentivized off-takers, (d) rely upon proven commercial 
technologies, and (e) originated by programmatic clients.
We believe that our long history of climate solutions 
investing, the experience, expertise and relationships of our 
management team, the anticipated credit strength of the 
obligors or investees involved in our investments and the 
size and growth potential of our market, position us well to 
capitalize on our strategy.

Executive Compensation Program Objectives
The Compensation Committee is responsible for establishing 
and 
administering 
our 
policies 
that 
relate 
to 
the 
compensation of our NEOs. We are committed to providing 
an executive compensation program that encourages and 
rewards strong financial and operational performance and 
supports the following goals and philosophies:
• aligning our leadership team’s interests with those of our 
stockholders, including our continued investment in 
solutions that advance the energy transition, reduce 
carbon 
emissions, 
and 
increase 
resilience 
to 
climate change;
• motivating and rewarding our leadership team for 
executing our operational plans with a focus on 
sustainable long-term growth in a manner that is consistent 
with appropriate risk-taking based on sound corporate 
governance practices; and
• attracting and retaining an experienced and effective 
leadership team while also maintaining an appropriate 
expense structure.
Structure of Our Executive Compensation Program
As discussed in more detail in this CD&A, our executive 
compensation program is comprised of the following 
primary compensation elements:
• base salary, which is an element of compensation set at 
levels that are commensurate with our NEOs’ positions 
and that provides fixed pay to attract and retain our 
NEOs, 
taking 
into 
account 
our 
budgeted 
operating expenses;
• incentive compensation (annual bonus) that is payable 
after the performance period has been completed in cash 
or in equity that vests over time; and
• long-term equity incentive program comprised of awards 
subject to both time-based and performance-based vesting 
that are designed to meet both our long-term growth and 
retention objectives.
Pay Mix
In determining the mix of compensation among these 
elements, attention is given to the elements and the mix of 
pay as well as ensuring that employees’ awards align with 
stockholders’ value. As illustrated below, the Compensation 
Committee continued to structure executive compensation in 
2024 so that a significant portion of the target total direct 
compensation (TDC) of our CEO and the other NEOs was 
“at-risk” performance-based compensation, with the actual 
value realized subject to the achievement of short-term or 
long-term corporate and financial performance goals. For 
2024, approximately 59% of Mr. Lipson’s target TDC, and 
an average of 54% of our other NEO’s target TDC, was 
structured as “at-risk” performance-based compensation, as 
illustrated below:
CEO FY 2024 Target TDC Mix
Average Non-CEO FY 2024 Target TDC Mix
EXECUTIVE COMPENSATION
EXECUTIVE SUMMARY
HASI Proxy Statement 2025

For 2024, over 80% of our targeted executive compensation was variable or equity-based (as opposed to a fixed cash 
amount) as shown below:

The Compensation Committee believes having a significant portion of variable or equity-based compensation achieves our 
goals of encouraging high performance, promoting accountability, retaining skilled and diverse leadership and motivating 
our executives to achieve our business objectives and aligning their interests with those of our stockholders.
Our Pay for Performance Alignment
The Committee reviews realizable pay versus TSR annually 
relative to our peer group as an effective way to evaluate 
the pay and performance relationship. The following graph 
provides a historical view of realizable pay-for-performance 
alignment for our CEO against the Company's July 2024 
peer group for the period of 2021-2023. Findings from our 
analysis indicate strong alignment between our CEO 
realizable pay and TSR rankings, reflecting competitive total 
pay 
levels, 
rigorous 
performance 
standards, 
and 
performance measures that are aligned with the key drivers 
of stockholder value. Our relative TSR performance is at the 
37th percentile and CEO realizable pay3 is at the 38th 
percentile of the peer group.
Three-Year CEO TDC Realizable Percent Rank
A significant portion of our NEOs' compensation is tied to 
company performance over three-year performance cycles. 
The long-term equity incentives granted are only eligible to 
be earned if the Company achieves rigorous relative TSR, 
absolute TSR, and/or cumulative adjusted earnings per 
share (“Cumulative Adjusted EPS”) goals. The details of our 
long-term incentive programs are further detailed below. 
The earned value of all long-term incentive equity awards 
will depend on the portion, if any, earned and the 
Company's share price. Based on estimates as of December 
31, 2024, 2023 performance-based LTIP units are currently 
tracking below target and 2024 performance-based LTIP 
units are currently tracking above target. The graph below 
illustrates the target compensation and realizable pay of our 
former CEO, Mr. Eckel, for 2022 and for our current CEO, 
Mr. Lipson, for 2023 and 2024.
CEO Compensation: Target vs. Realizable Value
EXECUTIVE COMPENSATION
OUR PAY FOR PERFORMANCE ALIGNMENT

HASI Proxy Statement 2025
(3) 
Total realizable pay for our CEO and the peer group CEOs is defined as the sum of the following components: actual base salary, actual short-term incentive payouts, and long-term 
incentive awards granted over the preceding three-year period comprised of time-based restricted shares/units and in-the-money stock options valued using closing share prices at the end 
of the period and performance-based awards valued assuming either actual performance or estimated performance-to-date and closing share prices at the end of the period. 

The following chart compares the target compensation 
values and realizable value for the compensation awarded 
during the three-year period from 2022 to 2024. 
Compensation for our former CEO, Mr. Eckel, is included 
for 2022, and compensation for our current CEO, Mr. 
Lipson, is included for 2023 and 2024. The CEO's 
realizable compensation for the three-year period of $19.4 
million is -9% below the $21.4 million target compensation 
for the same period, noting 2023 and 2024 performance-
based LTIP units have not yet been determined. Based on 
estimates as of December 31, 2024, the CEO’s realizable 
value of all time- and performance-based LTIP units for the 
three-year period of $9.6 million is -35% below the $14.8 
million target value for the same period. During this same 
three-year period, our annualized TSR was -20%. This 
demonstrates 
alignment 
between 
actual 
pay 
and 
performance versus expectations as reflected in the 
aggregate realizable pay values for the last three years.
A comparison of the realizable value of long-term equity 
incentive awards as of December 31, 2024, against the 
target compensation values indicates how compensation 
outcomes may be impacted by our performance. Such a 
comparison also shows the degree of alignment between 
our stock performance and the level of compensation 
provided to executives.

Our Executive Compensation Program Best Practices
Our executive compensation program incorporates our board of directors’ strong commitment to good governance:
WHAT WE DO:
WHAT WE DO NOT DO:
  Structure compensation with a target that is predominantly 
variable based on company and stock performance
   Provide Section 280G gross-up payments
  Align short-term and long-term executive incentive plan 
targets with business goals and stockholder interests
   Reward executives for taking excessive, inappropriate, or 
unnecessary risks
  Retain an independent compensation consultant to advise 
the Compensation Committee
   Utilize an equity incentive plan that allows repricing of stock 
options without prior stockholder approval
  Maintain a comprehensive “clawback” policy that applies 
to our NEOs
   Provide multi-year guaranteed salary increases or non-
performance-based bonus arrangements
  Use multi-year performance metrics that compare our 
performance to external benchmarks
   Rely exclusively on any single metric such as total stockholder 
return as our only performance metric
  Maintain a best-practices insider trading policy
   Provide incentive awards for below-threshold performance
  Review and consider total compensation for each NEO 
against a peer group (as defined below)
   Provide excessive executive perquisites
  Maintain a best-practices stock ownership guidelines for 
NEOs and Directors
   Utilize an equity incentive plan that provides for equity awards 
subject to a minimum vesting period of less than one year
  Re-evaluate and update the composition of our peer group 
periodically, particularly in light of our significant growth 
and recent change in business structure
   Permit hedging, and pledging and margin accounts related to 
our Common Stock
  Provide minimum thresholds for vesting of performance-
based equity awards
   Incorporate single trigger vesting for cash compensation under 
our NEO employment agreements

Stock Ownership Guidelines for Named Executive Officers
Under our stock ownership guidelines, each NEO must hold an ownership stake in the Company that is significant in 
comparison to their base salary. The aggregate value of stock ownership required to be retained by our NEOs is:
• Executive Chair: six times base salary;
• Chief Executive Officer and President: six times base salary; and
• all other NEOs: three times base salary.
Each NEO has five years to comply from the later of the date they become covered under this policy or the date the policy 
was originally adopted. Until the individual is in compliance, NEOs must retain 50% of any equity grants, net of any shares 
withheld or sold to satisfy taxes. Stock ownership for the purpose of these guidelines includes shares of Common Stock, 
restricted stock, OP units (includes LTIP units) and unvested OP units (includes LTIP units) held by the covered individual but 
excludes RSUs.
Process for Setting Executive Compensation
The Compensation Committee has primary responsibility for 
setting and approving the compensation of our chief 
executive officer and, upon the recommendation of our 
chief 
executive 
officer, 
reviewing 
and 
approving 
compensation for our other NEOs in a manner that is 
effective and consistent with our overall executive 
compensation strategy. As part of that responsibility, the 
Compensation Committee reviews the performance of each 
of our NEOs on an individual basis. As part of its process 
for reviewing the performance of our NEOs for 2024, the 
Compensation Committee considered the recommendations 
of Mr. Lipson related to the compensation of our NEOs.
The 
Compensation 
Committee 
typically 
reviews 
compensation levels for our NEOs near the beginning of 
each calendar year when determining base salaries and 
budgeted amounts for total compensation for the new fiscal 
year, and then meets again following the end of such fiscal 
year to review the Company’s and the NEOs’ actual 
performance, at which time it makes determinations with 
respect to adjustments to base salary, annual bonuses and 
our long-term equity incentive program. The Compensation 
Committee also meets periodically during the fiscal year to 
review 
the 
Company’s 
performance 
and 
other 
compensation matters, such as quarterly bonus accruals. As 
part of its annual review of the compensation paid to our 
NEOs, the Compensation Committee typically considers a 
number 
of 
factors 
in 
determining 
or 
structuring 
compensation, including the nature of the executive’s job 
and the responsibilities related thereto, the executive’s job 
performance compared to goals and objectives established 
for the Company and the executive at the beginning of the 
year, the experience level of the executive in his or her 
current position, the compensation levels of competitive jobs 
within our peer group (as defined below), our financial 
performance and financial condition, the execution of our 
investment 
and 
financing 
strategy, 
the 
impact 
of 
compensation determinations on our budgeted operating 
expense ratios and certain other quantitative and qualitative 
factors. These factors described above may vary from year 
to year in importance to, and usage by, the Compensation 
Committee, depending upon market conditions, corporate 
priorities and individual circumstances.
The 
Compensation 
Committee 
works 
jointly 
with 
management and the compensation consultant to design 
and implement a compensation plan that combines the 
elements of current cash compensation in the form of a base 
salary, an annual bonus (payable in cash and/or equity) 
and long-term equity incentive compensation in one plan, 
which we refer to as the executive compensation program, 
the components of which are described below. The 
Compensation Committee and our board of directors 
approved the program on an annual basis for the purpose 
of (i) attracting and retaining top performing employees, 
(ii) motivating employees by tying compensation directly to 
our financial performance, and (iii) rewarding exceptional 
individual performance that supports our overall objectives. 
The Compensation Committee believes that by utilizing both 
cash 
and 
equity 
incentive 
awards, 
the 
executive 
compensation program allows us to more closely match the 
incentives of our NEOs with both the long and short-term 
goals of the business while also improving our ability to 
monitor the results of our compensation program.
The Compensation Committee has the authority to consult 
and retain internal and external advisors as needed. In 
determining the compensation of our NEOs and our board 
of directors, the Compensation Committee has elected to 
utilize a variety of resources, including, from time to time, 
reports, information and advice provided by leading 
national and regional firms specializing in providing 
compensation consulting services to public companies. 
Since 2018, the Compensation Committee has engaged 
Pay Governance, a compensation consulting firm, to report 
EXECUTIVE COMPENSATION
STOCK OWNERSHIP GUIDELINES FOR NAMED EXECUTIVE OFFICERS
46
HASI Proxy Statement 2025

to the Compensation Committee regarding the setting of 
certain annual bonus targets for our NEOs. Starting in 
2019, the Compensation Committee has engaged Pay 
Governance to provide advice regarding the executive 
compensation program for our senior management team 
and 
board 
of 
directors, 
including 
analysis 
and 
recommendations regarding (1) base salaries, annual 
bonuses, including the mix of cash and equity, and 
long-term 
incentive 
compensation 
for 
our 
executive 
management team, (2) the director compensation program 
for independent members of our board of directors, and 
(3)  other matters as requested by the Compensation 
Committee.
Executive Compensation Program Peer Group Criteria and Composition
As part of the annual review of compensation payable to 
each of our NEOs, the Compensation Committee typically 
considers the compensation practices and levels at other 
companies that it deems generally comparable in structure 
and strategy. We sometimes refer to this group as our “peer 
group” for purposes of determining compensation. 
In preparation for our board of directors’ potential approval 
of 
the 
revocation 
of 
our 
REIT 
status 
effective 
January  1,  2024, and to assist the Compensation 
Committee in its selection of a peer group against which to 
compare existing and proposed executive compensation 
levels for 2024, in July 2023, Pay Governance used 
several quantitative and qualitative criteria, including the 
primary selection and refinement criteria listed below, to 
review existing and potential peer group companies in 
support of the Compensation Committee’s desire to 
rebalance the peer set to de-emphasize the number of REITs 
in the group while also making refinements to better reflect 
the diverse nature of the Company’s business. The 
Compensation Committee also expressed a desire to 
increase the overall size of the peer group in order for it to 
be (i) a sufficiently large sample size to ensure robust 
findings and accommodate changes in composition over 
time due to M&A activity and changes in size, (ii) of a 
composition which better reflected the unique nature of the 
Company’s business, and (iii) relevant in terms of the 
Company’s implied market capitalization, which has 
historically been the primary scoping criteria used by the 
Company for its peer group. In contrast to revenue, market 
capitalization is the most relevant indicator of size and how 
investors view the Company relative to competitors, 
followed by total managed assets in relevance. Revenue 
does not accurately reflect the complexity and scope of our 
business operations 
within our industry and for other companies in adjacent 
industries with similar business models. It also does not 
capture the profits earned from our equity method 
investments that are not included in our stated total revenue 
per GAAP reporting requirements.4  Accordingly, the 
Compensation Committee removed four REITs from the peer 
group utilized by the Compensation Committee in setting 
2023 compensation and added seven new companies that 
included asset managers, renewables equipment suppliers, 
and energy services/efficiency companies, which met the 
applicable criteria and would position the Company 
towards the median for market cap. As a result, the 
executive 
compensation 
set 
by 
the 
Compensation 
Committee for 2024 was based on an updated peer group 
of 18 companies that included asset managers, renewables 
equipment suppliers, energy services and efficiency 
companies and internally managed mortgage REITs, with 
median market capitalization of $3.0 billion, as compared 
to our market capitalization at the same time of 
approximately $2.6 billion.
For 2025, based on a July 2024 Pay Governance peer 
group report, the Compensation Committee determined that 
no changes to the peer group were needed. The Company 
based its consideration of any 2025 NEO compensation 
adjustments on an October 2024 Pay Governance 
benchmark report, which compared the Company’s 
executive compensation against the same companies 
utilized as the 2024 peer group but for the removal of 
SunPower Corporation, which was delisted after declaring 
bankruptcy 
in 
August 
2024, 
with 
median 
market 
capitalization of $2.8 billion, as compared to our market 
capitalization 
at 
the 
same 
time 
of 
approximately 
$3.4 billion.

In reviewing the analysis provided by Pay Governance 
regarding the 2024 Peer Group, the Compensation 
Committee noted that HASI was slightly below the median 
of the peer group for the market capitalization criterion 
(42%) and was significantly above the median of the peer 
group for the total managed assets criterion (89%). The 
Compensation Committee believed that this represented a 
reasonable and appropriate balance among the key 
quantitative criteria, particularly given its view that market 
capitalization and total assets managed have the highest 
relevance in selecting peer companies for purposes of 
comparing compensation and the lack of peers available 
that meet all criteria as a result of the Company’s relatively 
unique position in the market. Although considered as part 
of our overall screening criteria, focusing solely on revenue
would result in a group of peers that neither compete with 
us for executive talent nor are relevant to our investors. 
None of the companies in our peer group were selected by 
virtue of revenue size alone.
We do not have a policy of targeting compensation for our 
NEOs to any specific level within the range of total 
compensation paid by our peer group (i.e., median, upper 
or lower); rather, we have attempted to structure our 
executive compensation program and to compensate our 
NEOs in a manner that is both adequately competitive to 
retain their services and rewards their performance, hard 
work and dedication, but is also consistent with our needs 
to maintain an appropriate expense structure.

PROCESS FOR SETTING EXECUTIVE COMPENSATION

HASI Proxy Statement 2025

Qualitative Factors
In any given year, and for any particular NEO, the 
Compensation Committee may consider a range of 
subjective or qualitative factors in setting our NEO’s 
compensation, including:
• our CEO’s recommendations and his assessment of the 
executive’s performance;
• the role the executive plays and the importance of such 
individual 
to 
the 
Company’s 
business 
strategy 
and objectives;
• differences in each executive’s tenure and experience;
• the responsibilities and particular nature of the functions 
performed or managed by the executive;
• ensuring our retention and motivation objectives; and
• the likely cost and difficulty that would be encountered in 
recruiting a replacement.
The Compensation Committee’s consideration of any 
particular factor may range from inapplicable to significant, 
depending 
upon 
the 
individual 
and 
period 
under 
consideration. The Compensation Committee does not 
assign relative weights or rankings to such factors. Rather, 
the Compensation Committee relies upon its members’ 
knowledge and judgment in assessing the various 
qualitative and quantitative inputs it receives as to each 
individual and makes compensation decisions accordingly.
In determining fiscal 2024 executive compensation, and in 
addition to the assessment of market and other specific 
factors described in the below discussion of the individual 
elements of compensation, the Compensation Committee 
broadly considered these qualitative factors in making its 
compensation decisions for each NEO. Given their tenure, 
track record and experience, the Committee considered 
each of the NEOs to be highly sought-after executives and 
thus 
potential 
candidates 
for 
recruitment 
by 
other companies. 
Scope of Authority of the Compensation Committee
The Compensation Committee has overall responsibility for 
approving, evaluating and, in some cases, recommending 
to our board of directors, on an annual basis, director and 
officer compensation plans, policies and programs of the 
Company including determining salaries, annual cash 
bonuses, equity awards, change in control and termination 
arrangements and director fees. Pursuant to its charter, the 
Compensation Committee has the sole authority to retain, 
                                                          
terminate and pay any compensation consultant to be used 
to assist in the evaluation of director and senior executive 
compensation, as well as the authority to retain special 
legal, accounting or other consultants to advise the 
Compensation Committee and may form subcommittees and 
delegate 
its 
authority

such 
subcommittees.

Executive Compensation Program Components
The following provides an overview of our approach to 
each primary element of our NEO compensation program 
and an analysis of the compensation paid under each of 
these elements. 
Equity incentives have been granted under the 2013 HA 
Sustainable Infrastructure Capital, Inc. Equity Incentive Plan, 
as previously amended (the “2013 Plan”), and the 
2022 Plan.

annually 
based 
on 
individual 
performance, level of pay relative to the 
market and our peer group, internal pay 
equity, and retention.
Annual Incentive Compensation 
(Cash and Equity)
• Provides an annual incentive or bonus 
based upon our overall corporate and 
individual performance as well as 
objective and subjective performance 
criteria that are aligned with the 
strategic direction of the Company.

and 
individual 
performance measures as well as 
objective and subjective performance 
criteria on an annual basis.
• Compensation Committee determines 
allocation between cash and equity on 
an annual basis, as well as the vesting 
criteria of the annual equity awards.
Long-term Incentive
Program (Equity)
• Provides equity-based incentives that 
contain 
multi-year 
vesting 
and/or 
performance criteria in order to further 
our retention objectives and align the 
interests of our NEOs with those of our 
stockholders 
over 
a

Base Salary
Base salary, which represents the fixed element of our 
executive compensation program, provides for basic 
economic security at a level that allows us to retain the 
executive’s 
services. 
The 
Compensation 
Committee 
generally establishes annual base salaries for our NEOs 
commensurate with the level of experience that the 
executive brings to the position, the nature of the 
responsibilities required of the executive, such as whether 
the executive is performing in multiple roles, how successful 
the executive is in achieving goals established by the 
Compensation Committee and the executive’s contributions 
                         
to the Company, but does not assign any specific weights 
to these factors. As discussed in other parts of this CD&A, 
the Compensation Committee also considers the size of the 
Company and our budgeted operating expenses in setting 
annual base salaries. Base salaries are reviewed and may 
be adjusted to better match competitive market levels, to 
ensure executive retention or to recognize an executive’s 
professional 
growth 
and 
development, 
increased 
responsibility or other discretionary factors. The table below 
reflects the annual salary of our NEOs with increases 
effective in April of each of the years:

The determination to increase base salaries in 2024 for certain of our NEOs was driven by the performance of our NEOs 
and our desire to establish a base salary that is competitive in the market. As of March 1, 2023, Mr. Eckel transitioned to 
the role of executive chair, Mr. Lipson became our chief executive officer and president and Mr. Pangburn became our 
CFO. 2023 salaries for Messrs. Eckel, Lipson and Pangburn reflect their new roles. In 2024, the employment agreements of 
Messrs. Eckel and Santoroski were amended; however, the amendments did not impact their base salaries. On March 1, 
2025, Mr. Eckel transitioned to the role of chair and his term of employment ended; Mr. Pangburn transitioned from his role 
as CFO to our chief revenue and strategy officer; and Mr. Rose transitioned to the role of Senior Managing Director and is 
no longer an executive officer of the Company. The 2025 salary for Messrs. Pangburn and Rose reflect their new roles.
Annual Incentive Compensation or Bonuses
Annual incentive compensation, in the form of cash 
incentive compensation and equity incentive awards subject 
to time-based vesting conditions, is available to each of the 
NEOs under our executive compensation program, with the 
Compensation 
Committee 
determining 
the 
allocation 
between cash and equity. Incentive compensation serves as 
a means of linking annual compensation both to our overall 
performance and to objective and subjective performance 
criteria 
that 
are 
aligned 
with 
the 
Company’s 
strategic direction.
We provided our NEOs with the opportunity to earn annual 
incentive compensation for achieving corporate financial 
and non-financial goals for performance in 2024. These 
bonus awards, which provide for no minimum award or 
guaranteed payment, are comprised of two parts: a 
quantitative component and a qualitative component.
The following chart summarizes the target bonus percentage 
and actual awarded bonus percentages for 2024 
calculated as a percentage of the base salary at the end of 
the respective year.

2024 Bonus Awards Awarded in 2025
For 2024, our NEO incentive compensation was weighted 
such that 90% was based on quantitative corporate 
performance measures and 10% was based on an 
evaluation of individual performance. The following table 
sets forth the quantitative corporate performance measure 
hurdles and corresponding incentive compensation payouts 
for each of the NEOs under the quantitative component of

Long-Term Incentive Program Granted in 2024
NEOs are eligible to participate in a long-term equity 
incentive program that is based upon our desire to 
(i) increase the executive’s ownership stake in the Company 
and better align the executive’s long-term interests with 
those 
of 
our 
stockholders, 
(ii) 
tie 
total 
incentive 
compensation (including equity incentive awards) to 
specified quantitative performance measures, (iii) increase 
the amount of non-cash, equity incentive compensation 
earned by our NEOs as a percentage of their total 
compensation, and (iv) provide our NEOs with a 
competitive balance of current cash compensation and 
equity 
compensation 
subject 
to 
time-based 
and 
performance-based vesting conditions that increases the 
executive’s incentive to remain with the Company over 
the longer-term.
To address the goal of aligning the interests of our NEOs 
with 
those 
of 
our 
stockholders, 
the 
Compensation 
Committee allocated 50% of the award to each of our 
NEOs in the form of either restricted stock units (“RSUs”) or, 
at the election of our NEOs, performance-based LTIP units 
that, upon conversion, may become Restricted Limited 
Partnership Units (“OP units”). Performance-based LTIP units 
vest only upon achievement of specified performance 
metrics. These performance awards subject our NEOs to the 
downside risk of a decrease in the value of their 
compensation if the returns to our stockholders do not match 
the returns of the index against which our returns are being 
measured (“Relative TSR”) or we do not achieve a specified 
Cumulative Adjusted EPS target. In addition, LTIP units are a 
special kind of partnership interest that have no value if 
there is not a positive partnership revaluation event, as 
defined by the U.S. Internal Revenue Service. Both Relative 
TSR and Cumulative Adjusted EPS goals are measured on 
an approximate three-year basis or such shorter period 
upon the occurrence of a change of control. The number of 
performance awards that may be earned ranges from 50% 
of target for threshold performance achievement, and 200% 
of target for outperformance achievement. Under the 
Relative TSR component, target units are earned only if our

total stockholder return is equal to or above the 55th 
percentile of the index. 
We believe that growth in stockholder return is important to 
investors and is an appropriate measure of our long-term 
success. The use of stockholder return was also based upon 
an analysis of the measures used by the other companies in 
our peer group. The Compensation Committee allocated the 
remaining portion of the annual award (50%) in the form of 
time-vested restricted Common Stock or, at the election of 
the officer, time-restricted LTIP units. This allocation satisfies 
the need for a useful retention tool, given that in our market, 
there is a demand for experienced executive talent. The 
service-based award furthers our goal of aligning the 
long-term interests of our NEOs with those of our 
stockholders as it subjects our NEOs to the downside risk of 
a decrease in compensation if the price of our Common 
Stock declines.

$25.96 per unit, the closing price of our Common Stock on the NYSE on March 1, 2024, the date of grant. The Cumulative Adjusted EPS units were valued at $12.98 per unit and the 
Relative TSR units were valued at $19.56 in each case by an independent appraisal.
Benefits
Benefits are also established based upon a determination of 
what is needed to aid in attracting and retaining executive 
talent, as well as providing long-term financial security to 
our employees and their families. The NEOs are eligible to 
participate in our health, dental and vision plans, and 
various insurance plans, including disability and life 
insurance, and in our 401(k) plan.
Timing of Certain Equity Awards
We do not currently grant awards of stock options, stock 
appreciation rights, or similar option-like awards as part of 
our compensation program. We do not time the disclosure
of material non-public information, or the granting of equity 
awards, for the purpose of impacting the value of NEO 
compensation.
Insider Trading Policy
We have adopted the statement of corporate policy 
regarding equity transactions (the "Insider Trading Policy"), 
which prohibits all directors, officers, employees, and 
consultants from engaging in any transaction involving the 
purchase, sale or transfer of Company securities based on 
material non-public information about the Company.  We 
also take appropriate steps to comply with applicable 
securities laws and regulations and stock exchange listing 
standards when we engage in transactions in our securities. 
We believe that our Insider Trading Policy and procedures 
are reasonably designed to promote compliance with 
insider trading laws, rules and regulations and listing 
standards applicable to the Company.  A copy of our 
Insider Trading Policy is filed as Exhibit 19.1 to our annual 
report on Form 10-K for the year ended December 31, 
2024, which was filed with the SEC on February 14, 
2025.

Severance Benefits Payable upon Termination of Employment or a Change 
in Control
In order to achieve our compensation objective of 
attracting, retaining and motivating qualified senior 
executives, we believe that we need to provide our NEOs 
with severance protections that are consistent with the 
severance protections offered by companies similar to us. 
Consistent with this philosophy, we believe that severance 
should be payable to our NEOs in the event their 
employments are terminated under certain circumstances. 
For more information regarding the terms of the employment 
agreements, see “—Narrative to Summary Compensation 
Table.” The employment agreements are reviewed annually 
by the Compensation Committee.
In April 2022, our board of directors approved our 
Retirement Policy with immediate effect, and an amended 
and restated Retirement Policy was approved by the board 
of directors in April 2024. Our Retirement Policy provides 
for full vesting at retirement of any time-based awards that 
were granted prior to the date of retirement. Further, the 
Retirement Policy permits the vesting of performance-based 
awards that were granted prior to the date of retirement 
according to the original vesting schedule of the award, 
subject to the achievement of the applicable performance 
measures. The Retirement Policy applies to employees 
whose chronological age plus number of years of total 
service for the Company reaches a total age of 65, 
provided the applicable employee has (1) reached an age 
of 50 years, or (2) has worked at the Company for at least 
five years. Employees who have been actively employed by 
the Company since before the date of our initial public 
offering are credited with five years of prior service for 
purposes of determining their eligibility at retirement. Our 
Retirement Policy applies to all employees who receive 
grants of equity awards, whether they are NEOs, executive 
officers or other employees. The Company reserves the right 
to waive, amend, terminate or discontinue the policy to the 
extent our board of directors determines that it is in the 
Company’s interest.
Tax Deductibility of Executive Compensation
Section 162(m) (“Section 162(m)”) of the Internal Revenue 
Code of 1986, as amended (the “Internal Revenue Code”), 
places a $1,000,000 limit on the amount of compensation 
that may be deducted annually by the Company on our tax 
return with respect to certain NEOs, defined as “covered 
members” under Section 162(m). In December 2020, final 
regulations around Section 162(m) were published, which 
pertain in part to up-REIT structures. The final regulations 
provide that the Company’s distributive share of any 
compensation deduction for amounts paid to our NEOs by 
our Operating Partnership after December 18, 2020, as 
well as time-based and performance-based restricted stock 
awards awarded after November 2, 2017, are subject to 
the Section 162(m) deduction limit. When the Company 
                                                                  
determines whether to use performance-based awards in its 
grants to NEOs, it keeps in mind that there is generally no 
tax deduction with respect to compensation for an NEO in 
excess of $1,000,000 a year, and the Company’s 
performance-based pay practices may change accordingly 
in the future. Although the Compensation Committee 
generally seeks to preserve the federal income tax 
deductibility of compensation paid, to maintain flexibility in 
compensating executives, including our NEOs, in a manner 
designed to promote our corporate goals, including 
retaining and incentivizing the NEOs, the Compensation 
Committee has not adopted a policy that all compensation 
must be deductible.
Adjustment or Recovery of Awards
The Company believes that it is in the best interests of the 
Company and its stockholders to create and maintain a 
culture that emphasizes integrity and accountability and that 
reinforces the Company’s overall compensation philosophy. 
In furtherance of this goal, our board of directors adopted a 
clawback 
policy 
that 
applies 
to 
performance 
or 
incentive-based compensation approved, awarded or 
granted to a Covered Executive (as defined below) and that 
provides for the possible recoupment of performance or 
incentive-based compensation in the event of an accounting 
restatement due to material noncompliance by the 
Company with any financial reporting requirements under 
the securities laws (other than due to a change 
in applicable accounting methods, rules or interpretations).
This means that any performance or incentive-based 
compensation, whether cash- or equity- denominated, paid 
to such Covered Executive during the three-year period 
preceding the publication of the restated financial 
statements which would have been lower had it been 
calculated based on such restated financial statements, is 
subject to adjustment. For the purposes of this clawback 
policy, the term “Covered Executive” shall mean any NEO 
as determined by the Compensation Committee pursuant to 
Item 402 of Regulation S-K and other key employees 
identified by the Compensation Committee, and includes 
our NEOs.

Relationship of Compensation Practices to Risk Management
When structuring our overall compensation practices for our 
employees generally, consideration is given as to whether 
the structure creates incentives for risk-taking behavior and 
therefore impacts our risk management practices. Attention 
is given to the elements and the mix of pay as well as 
ensuring 
that 
employees’ 
awards 
align 
with 
stockholders’ value. 
The 
Compensation 
Committee 
has 
assessed 
the 
compensation policies and practices for our employees, 
including our NEOs, and concluded that they do not create 
risks that are reasonably likely to have a material adverse 
effect on the Company. The Compensation Committee 
generally considers whether our compensation programs 
encourage excessive risk taking during its annual review of 
such programs, which typically occurs during the first 
quarter of each year.
Compensation Committee Report
The Compensation Committee has reviewed and discussed the CD&A section of this proxy statement with management,

Structure—Our Board of Directors—Committees”, we have 
amended the Compensation Committee’s charter to make 
the Compensation Committee primarily responsible for 
administering the 2022 Plan and for making grants under 
the plan. The Compensation Committee consists of at least 
two individuals, each of whom is intended to be, to the 
extent required by Rule 16b-3 under the Exchange Act, a 
non-employee director. If no compensation committee exists, 
our board of directors will exercise the functions of 
our committee.
Awards Under the 2022 Plan
Shares of Restricted Common Stock
A restricted stock award is an award of shares of Common 
Stock that are subject to restrictions on transferability and 
such other restrictions the Compensation Committee may 
impose at the date of grant. Grants of shares of restricted 
Common Stock will be subject to vesting schedules and 
other restrictions that the Compensation Committee sets. The 
restrictions may lapse separately or in combination at such 
times, 
under 
such 
circumstances, 
including, 
without 
limitation, a specified period of employment or the 
satisfaction of pre-established criteria, in such installments or 
otherwise, as the Compensation Committee may determine.
Except to the extent restricted under an applicable award 
agreement, a restricted stockholder has all of the rights of a 
stockholder, including, without limitation, the right to vote 
and the right to receive cash dividends on the shares of 
restricted Common Stock. Although we will pay dividends 
on shares of restricted Common Stock, whether or not 
vested, at the same rate and on the same date as on shares 
of our Common Stock (unless we provide otherwise in an 
award agreement), holders of shares of restricted Common 
Stock are prohibited from selling such shares until they vest.
Phantom Shares and RSUs
A phantom share represents a right to receive the fair 
market value of a share of Common Stock, or, if provided 
by the Compensation Committee, the right to receive the 
fair market value of a share of Common Stock in excess of 
a base value established by the Compensation Committee 
at the time of grant. A phantom share may also be known 
as a “Restricted Stock Unit” or “RSU,” which is an unfunded 
and unsecured promise to deliver shares of Common Stock, 
cash, other securities or other property, subject to certain 
restrictions (which may include, without limitation, a 
requirement that the grantee remain continuously employed 
or provide continuous services for a specified period of 
time). Our current practice is to refer to all such awards 
as RSUs.
EXECUTIVE COMPENSATION
2022 PLAN SUMMARY
HASI Proxy Statement 2025
63

RSUs will vest as provided in the applicable award 
agreement. 
Unless 
otherwise 
determined 
by 
the 
Compensation Committee at the time of the grant, RSUs 
may generally be settled in cash or by transfer of shares of 
Common Stock (as provided in the grant agreement).
Dividend Equivalents
A dividend equivalent is a right to receive (or have 
credited) the equivalent value (in cash or shares of Common 
Stock) of dividends paid on shares of Common Stock 
otherwise subject to an award. The Compensation 
Committee may provide that amounts payable with respect 
to dividend equivalents will be converted into cash or 
additional shares of Common Stock. The Compensation 
Committee will establish all other limitations and conditions 
of awards of dividend equivalents as it deems appropriate.
Restricted Limited Partnership Units
A restricted limited partnership unit may be granted as a 
unit in our operating partnership (an OP unit) or may 
include LTIP units, which are structured as profits interests in 
our operating partnership, providing distributions to the 
holder of the award based on the achievement of specified 
levels of profitability by the operating partnership or the 
achievement of certain goals or events. Initially, LTIP units 
will not have full parity with OP units with respect to 
liquidating distributions. Under the terms of the LTIP units, 
the operating partnership will revalue its assets upon the 
occurrence of certain specified events, and any increase in 
valuation from the time of grant until such event will be 
allocated first to the holders of LTIP units to equalize the 
capital accounts of such holders with the capital accounts of
OP unit holders. Upon equalization of the capital accounts 
of the holders of LTIP units with other holders of OP units, 
the LTIP units will achieve full parity with OP units of the 
operating partnership for all purposes, including with 
respect to liquidating distributions. If such parity is reached, 
vested LTIP units may be converted into an equal number of 
OP units and thereafter enjoy all the rights of OP units. The 
Compensation Committee will establish all other limitations 
and conditions of awards of restricted OP units as it 
deems appropriate.
Amendments and Termination
Our board of directors may amend the 2022 Plan as it 
deems advisable, except that it may not amend the 2022 
Plan in any way that would adversely affect a participant 
with respect to an award previously granted unless the 
amendment 
is 
required 
in 
order 
to 
comply 
with 
applicable laws.

This column describes the payments and benefits that become payable if the Company elects not to renew the applicable NEO’s employment agreement, if employment is terminated by 
the Company without cause, or if employment is terminated by the applicable NEO for good reason. For Mr. Eckel, the term “cause” means (i) conviction of, or plea of nolo contendere 
to, a felony involving moral turpitude, deceit, dishonesty or fraud (but excluding traffic violations) that is injurious to the business or reputation of the Company; (ii) willful and material 
misconduct in connection with the performance of his duties, including, without limitation, embezzlement or the misappropriation of funds or property of the Company; (iii) failure to 
adhere to the lawful directions of our board of directors, or to devote substantially all of his business time and efforts to the Company, in either event, which continues for a period of 30 
business days after written demand for corrective action is delivered by the Company; or (iv) material breach of (x) any covenant contained in the employment agreement; or (y) the other 
terms and provisions of the employment agreement and, in each case, failure to cure such breach within 10 days following written notice from the Company specifying such breach. For 
Messrs. Lipson, Pangburn, and Rose and Ms. Nickey, the term “cause” means the applicable NEO’s (i) commission of, and indictment for or formal admission to, a felony involving moral 
turpitude, deceit, dishonesty or fraud (but excluding traffic violations); (ii) willful and material misconduct in connection with the performance of the applicable NEO’s duties, including, 
without limitation, embezzlement or the misappropriation of funds or property of the Company; (iii) failure to adhere to the lawful directions of the CEO, to adhere to the Company’s 
policies and practices or to devote substantially all of the applicable NEO’s business time and efforts to the Company, which failure continues for a period of 30 business days after 
written demand for corrective action is delivered by the Company; or (iv) material breach of (x) any covenant contained in the employment agreement; or (y) the other terms and 
provisions of the employment agreement and, in each case, failure to cure such breach within 10 days following written notice from the Company specifying such breach.
The term “good reason” means (i) any change in job title or material diminution in the applicable NEO’s roles and responsibilities from those set forth in the employment agreements 
(including, without limitation, the assignment of duties inconsistent with the applicable NEO’s position or, for Mr. Eckel only, no longer being the chair of our board of directors and the 
senior-most executive of the Company); (ii) a reduction in the applicable NEO’s annual salary or annual bonus potential; (iii) a relocation of the Company’s headquarters outside a 30 
mile radius of Annapolis, MD or moving of the applicable NEO’s office or place of performance from the Company’s headquarters; (iv) a material breach by the Company of the 
employment agreement or any other material agreement between the applicable NEO and the Company; or (v) for Mr. Eckel only, there shall have occurred a change in control. For Mr. 
Rose, following a change in control the definition of good reason set forth is modified to delete all references to the term “material.” For Mr. Lipson, the definition is applicable only 
following a change in control and does not include references to the term “material.”
(2)
The term “disability” means that the applicable NEO has become physically or mentally incapable of performing the duties under the employment agreement and such disability has 
disabled the NEO for a cumulative period of 180 days within any 12-month period.
(3)
The term “change in control” is defined in the 2013 Plan or the 2022 Plan, as applicable.
(4)
Includes the value of accelerated vesting of outstanding equity awards granted to the applicable NEO. The acceleration value of the restricted stock was calculated using the closing price 
of $26.83 per share on December 31, 2024, the last trading day of 2024. For termination without cause, termination for good reason, non-renewal by the Company, death or disability, 
the number of performance shares reported is based on the target level of performance. For change in control, the number of performance shares reported is based on the actual level of 
performance through December 31, 2024.

CEO Compensation Pay Ratio
We believe our executive compensation program must be 
internally consistent and equitable to motivate our 
employees to create stockholder value. We monitor the 
relationship between the compensation of our executive 
officers and the compensation of our non-managerial 
employees. As required by Section 953(b) of the 
Dodd-Frank Wall Street Reform and Consumer Protection 
Act, we are providing disclosure regarding the ratio of the 
annual total compensation of Jeffrey Lipson, our chief 
executive officer during 2024, to that of our median 
employee in the table below.
HASI (2024)
CEO Compensation
$ 8,399,696 
Median Employee Compensation
$ 252,645 
CEO to Worker Ratio
33:1
The CEO Compensation is provided in the “Summary 
Compensation Table” above. We identified the median 
employee using the annual base salary and expected 
bonus, as of December 31, 2024, plus any long-term 
incentive equity awards granted in 2024 for all individuals, 
excluding our chief executive officer, who were employed 
by us on December 31, 2024, the last day of our payroll 
year (whether employed on a full-time, part-time, or 
seasonal 
basis). 
If 
the 
median 
employee’s 
total 
compensation 
was 
not 
comparable 
to 
the 
CEO 
Compensation, 
for 
example, 
because 
such 
median 
employee was hired at the end of the year and thus did not 
receive long-term incentive equity awards in 2024, we used 
the next lower employee who was comparable as the 
median employee. After identifying the median employee, 
we calculated annual total compensation for such employee 
using 
the 
same 
methodology 
we 
use 
for 
our 
CEO Compensation. 
2024 Pay Versus Performance Table
In accordance with rules adopted by the Securities and 
Exchange Commission pursuant to the Dodd-Frank Wall 
Street Reform and Consumer Protection Act of 2010, we 
provide the following disclosure regarding executive 
compensation for our principal executive officer (“PEO”) 
and Non-PEO NEOs and Company performance for the

For 2023 and 2024, the Peer Group TSR set forth in this table uses the ALPS Clean Energy ETF, which we also use in the stock performance graph required by Item 201(e) of Regulation 
S-K included in our Annual Report for the year ended December 31, 2024. The comparison assumes $100 was invested for the period starting December 31, 2019, through December 
31, 2024 in the Company and in the ALPS Clean Energy ETF, respectively. For 2020, 2021 and 2022, the Peer Group TSR uses the FTSE NAREIT All Equity REIT Index. ALPS Clean 
Energy ETF is a growing, US-based, well-diversified, mid-cap investor in climate-positive real assets that we believe is well positioned to serve as a peer group index. ALPS Clean Energy 
ETF is comprised of companies who generally own or operate assets similar to our investments in renewable energy projects as well other companies positively exposed to the energy 
transition. Historical stock performance is not necessarily indicative of future stock performance.

We determined Adjusted EPS to be the most important financial performance measure used to link Company performance to Compensation Actually Paid to our PEO and Non-PEO NEOs 
in 2024. See Item 7 to our Annual Report on Form 10-K, filed on February 14, 2025, for an explanation of Adjusted Earnings, including a reconciliation to the relevant GAAP measure. 
This performance measure may not have been the most important financial performance measure for prior years and we may determine a different financial performance measure to be 
the most important financial performance measure in future years.

Certain Relationships and Related Transactions
Indemnification Agreements for Officers and Directors
We have entered into indemnification agreements with members of our board of directors and our executive officers. These 
indemnification agreements provide indemnification to these persons by us to the maximum extent permitted by Delaware 
law and certain procedures for indemnification, including advancement by us of certain expenses relating to claims brought 
against these persons under certain circumstances.
Related Transactions Policy
In the Code of Conduct, we have a conflicts of interest policy that prohibits our directors, officers, consultants and 
employees who provide services to us from engaging in any transaction that involves an actual or potential conflict of 
interest with us unless pre-approved. Exceptions may be made only after review and approval of specific or general 
categories by our board of directors (in the case of executive officers or directors) and our chief legal officer (in the case of 
employees or consultants who are not executive officers and directors).
Meeting Information
Pursuant to the rules adopted by the SEC, we have 
provided access to our proxy materials over the Internet. 
Accordingly, we are sending a Notice of Internet 
Availability of Proxy Materials (the “Notice”) to our 
stockholders of record as of the Record Date. We believe 
that posting these materials on the Internet enables us to 
provide stockholders with the information that they need 
more quickly. It also lowers our costs of printing and 
delivering these materials and reduces the environmental 
impact of the Annual Meeting. The Notice and this proxy 
statement summarize the information you need to know to 
vote by proxy or online during the Annual Meeting via a 
live webcast.
All stockholders are cordially invited to attend the Annual 
Meeting virtually, which will be conducted solely via a live 
webcast. By hosting the Annual Meeting online, we are 
able to communicate more effectively with our stockholders, 
enable increased attendance and participation from 
locations around the world, and reduce costs, which aligns 
with our broader sustainability goals. The virtual meeting 
has been designed to provide the same rights to participate 
as you would have at an in-person meeting. During the 
upcoming virtual meeting, you may ask questions and will 
be able to vote your shares online from any remote location 
with Internet connectivity. We will respond to as many 
inquiries at the Annual Meeting as time allows and we will 
post the questions and answers from the meeting on the 
Company’s website promptly thereafter.
If you plan to attend the Annual Meeting online, you will 
need the 16-digit control number included in your Notice, 
on your proxy card or on the instructions that accompany 
your proxy materials. The Annual Meeting will begin 
promptly at 9:30 a.m., Eastern Time. Online check-in will 
begin at 9:15 a.m., Eastern Time, and you should allow 
ample time for the online check-in procedures.
You may attend the virtual Annual Meeting if you are a 
stockholder of record, a proxy holder for a stockholder of 
record, or a beneficial owner of our common stock, par 
value $0.01 per share (the “Common Stock”), with 
evidence of ownership.
If you are a registered holder of shares of Common Stock, 
as of the close of business on the Record Date, the Notice 
was sent directly to you and you may vote your shares of 
Common Stock during the Annual Meeting by attending via 
live webcast. If you hold shares of Common Stock in “street 
name” through a brokerage firm, bank, broker-dealer or 
other intermediary, the Notice was forwarded to you by 
such intermediary and you must follow the instructions 
provided by such intermediary regarding how to instruct 
such intermediary to vote your shares of Common Stock.

Meeting via webcast will not automatically revoke a 
stockholder’s previously submitted proxy unless such 
stockholder votes online during the Annual Meeting.
If your shares are held in street name and you desire to vote 
online during the virtual Annual Meeting, you will need a 
legal proxy from your bank, broker or other holder of 
record to be able to vote at the meeting.
You may attend the virtual Annual Meeting and 
vote 
your 
shares 
during 
the 
meeting 
at 
www.virtualshareholdermeeting.com/HASI2025 by using 
your 16-digit control number as the password and following 
the instructions provided to vote. We encourage you to 
access the meeting prior to the start time leaving ample time 
for the check in.
If you encounter any difficulties accessing the virtual Annual 
Meeting during the check-in time or meeting time, or you 
have any questions regarding how to use the virtual 
meeting platform, please call the technical support number 
posted on the virtual Annual Meeting meeting log-in page.
If your shares are held in street name and you desire to 
change your vote, you should contact the nominee holding 
shares for you (i.e., a brokerage firm, bank, broker-dealer 
or other intermediary) for instructions on how to do so. 
If a proxy is properly authorized without specifying any 
voting instructions and not revoked prior to the Annual 
Meeting, the shares of Common Stock represented by such 
proxy will be voted (1)  FOR  the election of the nominees 
named in this proxy statement as directors, to serve on our 
board of directors until our 2025 annual meeting of 
stockholders and until their successors are duly elected and 
qualify, (2) FOR the ratification of the appointment of Ernst 
& Young LLP as our independent registered public 
accounting firm for the fiscal year ending December 31, 
2025, and (3) FOR the approval of a non-binding advisory 
resolution approving the compensation of our NEOs as 
described in the Compensation Discussion and Analysis, the 
compensation tables and other narrative disclosure in this 
proxy statement. As to any other business that may properly 
come before the Annual Meeting or any postponements or 
adjournments thereof, the persons named as proxy holders 
on your proxy card will vote the shares of Common Stock 
represented by properly submitted proxies in their 
discretion. If you hold your shares in street name and do not 
give the nominee holding shares for you (i.e., a brokerage 
firm, bank, broker-dealer or other intermediary) specific 
voting instructions on the election of directors or the non-
binding 
advisory 
vote 
to 
approve 
our 
executive 
compensation , your shares will not be voted on these 
items, and a broker non-vote will occur. Broker non-votes 
and abstentions are each included in the determination of 
the number of shares of Common Stock present at the 
Annual Meeting for purposes of determining whether a 
quorum is present but will have no effect on the voting 
results for the election of directors or the non-binding 
advisory proposal to approve our executive compensation.
This proxy statement, the Notice of Annual Meeting of 
Stockholders and the related proxy card are first being 
made 
available 
to 
stockholders 
on 
or 
about 
April 22, 2025.
Annual Report
This proxy statement is accompanied by our Annual Report on Form 10-K for the year ended December 31, 2024 filed with 
the SEC on February 14, 2025.
Voting Securities and Record Date
Stockholders will be entitled to cast one vote for each share 
of Common Stock held of record at the close of business on 
the Record Date with respect to (i) the election of twelve 
directors to serve on our board of directors until our 2026 
annual meeting of stockholders and until their successors 
are duly elected and qualify, (ii) the ratification of the 
appointment of Ernst & Young LLP as our independent 
registered public accounting firm for the fiscal year ending 
December 31, 2025, (iii) a non-binding advisory resolution 
approving compensation of our Named Executive Officers 
as described in the Compensation Discussion and Analysis, 
the compensation tables and other narrative disclosure in 
this proxy statement and (iv) any other proposal for 
stockholder action that may properly come before the 
Annual 
Meeting 
or 
any 
postponements 
or 
adjournments thereof.
HASI Proxy Statement 2025

Stockholders who instruct their proxy to abstain should 
know that abstentions and broker non-votes are each 
included in the determination of the number of stockholders 
present at the Annual Meeting for the purpose of 
determining whether a quorum is present. A broker non-vote 
occurs when a nominee holding shares for a beneficial 
owner (i.e., a brokerage firm, bank, broker-dealer or other 
intermediary) returns a properly-executed proxy but does 
not vote on a particular proposal because such nominee 
does not have discretionary voting power for that particular 
matter and has not received instructions from the beneficial 
owner. Under the rules of the NYSE, the only item to be 
acted upon at the Annual Meeting with respect to which 
such nominee will be permitted to exercise voting discretion 
in the absence of voting instructions from the beneficial 
owner is the ratification of the appointment of Ernst & 
Young LLP as our independent registered public accounting 
firm for the fiscal year ending December 31, 2025. 
Therefore, if you hold your shares in street name, if your 
shares are present by proxy at the Annual Meeting, and do 
not give the nominee specific voting instructions on the 
election of directors or the non-binding advisory resolution 
approving our executive compensation, your shares will not 
be voted on these items, and a broker non-vote will occur. 
Broker non-votes and abstentions will have no effect on the 
voting results for any of the proposals.
The presence, by attending online during the Annual 
Meeting via webcast or by proxy, of holders of Common 
Stock entitled to cast a majority of all the votes entitled to be 
cast at the Annual Meeting shall constitute a quorum. The 
disposition of business scheduled to come before the 
Annual Meeting, assuming a quorum is present, will require 
the following affirmative votes:
• for the election of a director, a plurality of all the votes 
cast in the election of directors at the Annual Meeting,
• for the ratification of the appointment of our independent 
registered public accounting firm, a majority of all the 
votes cast on the proposal, and
• for the approval of the non-binding advisory resolution to 
approve the compensation of our Named Executive 
Officers, a majority of all the votes cast on the proposal.
We have a majority vote policy for the election of directors. 
In an uncontested election, any nominee for director who 
receives a greater number of votes “withheld” from his or 
her election than votes “for” such election is required to 
tender his or her resignation to our board of directors. The 
NGCR Committee is required to promptly consider the 
resignation and make a recommendation to our board of 
directors with respect to the tendered resignation. Our 
board of directors is required to take action with respect to 
this recommendation. Any director who tenders his or her 
resignation to our board of directors will not participate in 
the NGCR Committee’s consideration or board action 
regarding whether to accept such tendered resignation. The 
policy is more fully described above in the “Proposal No. 1 
Election of Directors—Majority Vote Policy” section of this 
proxy statement.
If any nominee named in this proxy statement is unwilling or 
unable to serve as a director, our board of directors may 
nominate another individual for election as a director at the 
Annual Meeting, and the persons named as proxy holders 
will vote for the election of any substitute nominee.
The vote on compensation is advisory and not binding on 
our board of directors. However, our board of directors and 
the 
Compensation 
Committee 
value 
all 
stockholder 
feedback and will consider the outcome of the votes in 
reviewing executive compensation. 
Other Matters
Our board of directors knows of no other business to be presented at the Annual Meeting. The proxies for the Annual 
Meeting confer discretionary authority on the persons named therein as proxy holders to vote on any matter proposed by 
stockholders for consideration at the Annual Meeting. As to any other business which may properly come before the Annual 
Meeting, the persons named as proxy holders on your proxy card will vote the shares of Common Stock represented by 
properly submitted proxies in their discretion.

Submission of Stockholder Proposals
Any stockholder intending to present a proposal at an 
annual meeting of stockholders and have the proposal 
included in the proxy statement and proxy card for such 
meeting (pursuant to Rule 14a-8 of the Exchange Act) must, 
in addition to complying with the applicable laws and 
regulations governing submissions of such proposals, submit 
the proposal in writing to us no later than 5:00 p.m., 
Eastern Time, on December 23, 2025 and must otherwise 
be in compliance with the requirements of the SEC’s

Our Bylaws currently provide that any stockholder intending 
to nominate a director or present a stockholder proposal of 
other business for consideration at the 2025 annual 
meeting of stockholders, but not intending for such a 
nomination or proposal to be considered for inclusion in our 
proxy statement (i.e., not pursuant to Rule 14a-8 of the 
Exchange Act), must notify us in writing no earlier than the 
150th day and not later than 5:00 p.m., Eastern Time, on 
the 120th day prior to the first anniversary of the date of 
the proxy statement for the immediately preceding annual 
meeting of stockholders; provided, however, that in the 
event that the annual meeting with respect to which such 
notice is to be tendered is not held within 30 days before or 
70 days after the anniversary of the date of the preceding 
annual meeting of stockholders, to be timely, notice by the 
stockholder must be received no earlier than the 150th day 
and not later than 5:00 p.m., Eastern Time, on the later of 
the 120th day prior to the first anniversary of the date of 
the immediately preceding annual meeting of stockholders, 
as originally convened, or the close of business on the tenth 
day following the day on which public announcement of the 
date of such meeting is first made and must otherwise 
comply with requirements set forth in our Bylaws. 
Accordingly, to nominate a director candidate for election 
or present a stockholder proposal of other business for 
consideration at our 2025 annual meeting of stockholders, 
stockholders must submit the nomination or proposal, in 
writing, 
by 
5:00 
p.m., 
Eastern 
Time, 
on 
December  23,  2025, but in no event earlier than 
November 23, 2025.
In addition to satisfying the foregoing advance notice 
procedures set forth in our Bylaws, to comply with the 
universal proxy rules under the Exchange Act stockholders 
who intend to solicit proxies in support of director nominees 
other than our nominees must comply with, and provide 
notice that sets forth the information required by, Rule 
14a-19 under the Exchange Act.
Any such nomination or proposal should be sent to Steven 
L. Chuslo, our executive vice president, chief legal officer 
and secretary, at HA Sustainable Infrastructure Capital, 
Inc., 1 Park Place, Suite 200, Annapolis, Maryland 21401, 
and, to the extent applicable, must include the information 
and other materials required by our Bylaws.
Our board of directors knows of no other matters or 
business to be presented for consideration at the Annual 
Meeting. If, however, any other matters properly come 
before the Annual Meeting or any postponements or 
adjournments thereof, it is the intention of the persons 
named in the enclosed proxy to vote such proxy in 
accordance with their discretion on any such matters. The 
persons named in the enclosed proxy may also, if they 
deem it advisable, vote such proxy to adjourn the Annual 
Meeting from time to time.

Forward-Looking Statements
We make forward-looking statements in this Annual Report on 
Form 10-K (“Form 10-K”) within the meaning of Section 27A of 
the Securities Act of 1933, as amended (the “Securities Act”), and 
Section 21E of the Securities Exchange Act of 1934, as amended 
(the “Exchange Act”) that are subject to risks and uncertainties. 
For these statements, we claim the protections of the safe harbor 
for forward-looking statements contained in such Sections. These 
forward-looking statements include information about possible or 
assumed future results of our business, financial condition, liquidity, 
results of operations, plans and objectives. When we use the words 
“believe,” “expect,” “anticipate,” “estimate,” “plan,” “continue,” 
“intend,” “should,” “may” or similar expressions, we intend to 
identify forward-looking statements. However, the absence of 
these words or similar expressions does not mean that a statement 
is not forward-looking. All statements that address operating 
performance, events or developments that we expect or anticipate 
will occur in the future are forward-looking statements.
Forward-looking statements are subject to significant risks and 
uncertainties. Investors are cautioned against placing undue reliance 
on such statements. Actual results may differ materially from those 
set forth in the forward-looking statements. Accordingly, any such 
statements are qualified in their entirety by reference to, and are 
accompanied by, important factors included in Part I, Item 1A. Risk 
Factors (in addition to any assumptions and other factors referred 
to specifically in connection with such forward-looking statements) 
that could have a significant impact on our operations and financial 
results, and could cause our actual results to differ materially from 
those contained or implied in forward-looking statements made by 
or on our behalf in this Form 10-K, in presentations, on our websites, 
in response to questions or otherwise.
Any forward-looking statement speaks only as of the date on which 
such statement is made, and we undertake no obligation to update 
any forward-looking statement to reflect events or circumstances, 
including, but not limited to, unanticipated events, after the date on 
which such statement is made, unless otherwise required by law. New 
factors emerge from time to time and it is not possible for management 
to predict all of such factors, nor can it assess the impact of each 
such factor on the business or the extent to which any factor, or 
combination of factors, may cause actual results to differ materially 
from those contained or implied in any forward-looking statement.

HASI Form 10-K

Risk Factor Summary
An investment in our securities involves risk. You should carefully 
consider the risks summarized in Item 1A, “Risk Factors” included in 
this report. These risks include, but are not limited to, the following:
Risks Related to Our Business and Our Industry
• Our business depends in part on U.S. federal, state and local 
government policies and a decline in the level of government 
support could harm our business.
• If the market for various types of climate solutions projects or the 
investment techniques related to such projects do not develop as 
we anticipate, new business generation in this target area may 
be adversely impacted.
• We are subject to risks related to our sustainability and governance 
activities and disclosures.
• We operate in a competitive market, which may impact the terms 
of the investments we make.
Risks Related to Our Assets and Projects in Which We Invest
• Changes in interest rates could adversely affect the value of our 
assets and negatively affect our profitability.
• The lack of liquidity of our assets may adversely affect our 
business, including our ability to value our assets.
• The preparation of our financial statements, including provision for 
loan losses, involves use of estimates, judgments and assumptions, 
and our financial statements may be materially affected if our 
estimates prove to be incorrect.
• We rely on our project sponsors for financial reporting related 
to our project companies, and our financial statements may be 
materially affected if the financial reporting related to our project 
companies proves to be incorrect.
• Our investments are subject to delinquency, foreclosure and loss, 
any or all of which could result in losses to us.
• Our subordinated and mezzanine debt and equity investments, 
many of which are illiquid with no readily available market, 
involve a degree of risk.
• We either do not control or jointly control the projects in which 
we invest, which may result in the project owner making certain 
business decisions or taking risks with which we disagree. 
• Many of our assets depend on revenues from third-party 
contractual arrangements, including PPAs, that expose the projects 
to various risks.
• Portions of the electricity our assets generate is sold on the open 
market at spot-market prices. A prolonged environment of prices 
for natural gas, or other conventional fuel sources, below the 
levels at which we assumed when underwriting these investments, 
may have a material adverse effect on our long-term business 
prospects, financial condition and results of operations.
• Some of the projects in which we invest may require substantial 
operating or capital expenditures in the future.
• We invest in projects which rely on third parties to manufacture 
quality products or provide reliable services in a timely manner and 
the failure of these third parties could cause project performance 
to be adversely affected.
• Our insurance and contractual protections may not always cover 
lost revenue, increased expenses or liquidated damages payments.
• Energy efficiency, renewable energy and other sustainable 
infrastructure projects are subject to performance risks, including 
risks due to extreme weather events, that could impact the 
repayment of and the return on our assets.
Risks Related to Our Company and Structure
• Our management and employees depend on information systems 
and system failures could significantly disrupt our business, which 
may, in turn, negatively affect the market price of our common 
stock and our ability to pay dividends to our stockholders.
• Major public health issues and related disruptions in the U.S. and 
global economy and financial markets could adversely impact or 
disrupt our financial condition and results of operations.
• Our qualification as a REIT for prior taxable years depends on 
interpretation of highly technical and complex legal provisions, and 
our failure to qualify as a REIT for prior taxable years would subject 
us to U.S. federal income tax and potentially state and local tax.
• Our ability to utilize our NOLs and other carryforwards may 
be limited.
Risks Relating to Regulation
• We cannot predict the unintended consequences and market 
distortions that may stem from far-ranging governmental 
intervention in the economic and financial system or from 
regulatory reform of the oversight of financial markets.
• Loss of our 1940 Act exemptions may adversely affect us, the 
market price of shares of our common stock and our ability to 
distribute dividends.
Risks Related to Our Borrowings and Hedging
• An increase in our borrowing costs relative to the interest we 
receive on our assets may adversely affect our profitability and our 
cash available for distribution to our stockholders. Our borrowings 
may have a shorter duration than our assets.
• While we have an established Board-approved leverage limit, 
our Board of Directors (our “Board”) may change our financial 
leverage guidelines without stockholder consent.

HASI Form 10-K

Part I
In this Form 10-K, unless specifically stated otherwise or the context 
otherwise indicates, references to “we,” “our,” “us,” “HASI,” and 
“our company” refer to HA Sustainable Infrastructure Capital, 
Inc., a Delaware corporation and any of our subsidiaries. Hannon 
Armstrong Sustainable Infrastructure, L.P., a Delaware limited 
partnership, is a subsidiary of which we are the sole general 
partner and to which we refer in this Form 10-K as our “Operating 
Partnership.” Our business is focused on reducing the impact of 
greenhouse gases that have been scientifically linked to climate 
change. We refer to these gases, which are often for consistency 
expressed as carbon dioxide equivalents, as carbon emissions.
Item 1.
Business
Company Overview
HASI is an investor in sustainable infrastructure assets advancing the energy transition. Our investment strategy is focused on actively 
partnering with clients to deploy capital primarily in income-generating real assets that are supported by long-term recurring cash flows. This 
strategy has enabled us to generate attractive risk-adjusted returns and provide stockholders with diversified exposure to the energy transition.
We are internally managed by an executive team that has extensive relevant industry knowledge and experience, and a team of over 150 
full-time investment, operating, and technical professionals. We have long-standing, programmatic relationships with some of the leading U.S. 
clean energy project developers, owners and operators, utilities, and energy service companies, which provide recurring, investment and 
fee-generating opportunities, while also enabling scale benefits and operational and transactional efficiencies. Partnering with these clients, 
we are able to earn attractive risk-adjusted returns by investing in a variety of asset classes across our three primary climate solutions markets:
Behind the Meter (BTM)
Grid-Connected (GC)
Fuels, Transport, and Nature (FTN)
• Residential solar and storage
• Utility-scale solar
• Renewable natural gas
• Community, commercial, and 
industrial solar and storage
• Onshore wind
• Fleet decarbonization
• Energy efficiency
• Battery energy storage systems
• Ecological restoration
Through December 31, 2024, we have cumulatively closed more 
than 1,250 investments spanning more than 100 different clients 
since 1998. Our investments take many forms, including equity, joint 
ventures, real estate, commercial and government receivables or 
securities, and other financing transactions. With over $13 billion 
in managed assets, including a portfolio of $6.6 billion in assets 
retained on our balance sheet, our investments span a broad range 
of sustainable infrastructure assets, which in aggregate represent more 
than 7 gigawatts (GW) of solar power capacity (including 3.5 GW 
utility-scale) and more than 4 GW of onshore wind power capacity–
which together generate 20 terawatt-hours (TWh) of electricity 
annually–as well as battery storage capacity of more than 1 GW, 
RNG facilities with the capacity to produce more than 40 million 
diesel gallons-equivalent, more than 1,000 commercial fleet vehicles, 
and more than 375 energy efficiency projects. In aggregate, we 
estimate our investments enable the avoidance of approximately 
8 million metric tons of carbon dioxide equivalent annually (based 
on the aggregate of each of our project’s first year of operations).
We completed approximately $2.3 billion of transactions during 
both 2024 and 2023, and from 2020 through 2024 we have 
closed more than $10 billion of transactions. As of December 31, 
2024, our managed assets totaled approximately $13.7 billion, and 
generally fall into one of three categories: (1) our Portfolio, which 
primarily consists of receivables and equity method investments we 
have retained on our balance sheet, (2) the portion of assets in our 
co-investment structures that are not included in our Portfolio but held 
by our investment partners in these structures, and (3) assets we have 
securitized by transferring all or a portion of the economics of the 
transaction, typically using securitization trusts, to institutional investors 
in exchange for cash and, in certain cases, residual interests in the 
trusts and ongoing fees. 
As of December 31, 2024, our Portfolio totaled approximately 
$6.6 billion, consisting of over 550 investments. Approximately 
47% of our Portfolio is invested in BTM assets, approximately 39% 
invested in GC assets, and approximately 14% invested in FTN 
investments. The mix of our Portfolio is expected to vary over time, 
as we seek to manage the diversity of our Portfolio by, among other 
factors, project type, project operator, type of investment, type of 
technology, transaction size, geography, obligor, and maturity.

As of December 31, 2024, assets held in our co-investment 
structures that were not consolidated as part of our Portfolio 
but held by our investment partners in these structures totaled 
approximately $300 million. As of December 31, 2024, we also 
managed approximately $6.8 billion in securitized assets held in 
unconsolidated securitization trusts.
The returns we generate on our investments are generally derived 
from five primary sources: (1) interest income, (2) income from 
equity method investments, (3) gains on the sale of assets through 
securitizations, (4) fee revenue from co-investment vehicles and 
securitized assets that we manage, and (5) residual income 
generated by the portion of securitized assets that we have 
retained. Management operates and evaluates the business with a 
particular focus on growing Adjusted earnings per share, as well as 
Adjusted Net Investment Income, which represents interest income 
and rental income revenue plus equity method investments earnings 
(a non-GAAP adjustment to our income from equity method 
investments that we believe is a useful indicator of the underlying 
economics of our investments) less interest expense and excluding 
the amortization of real estate intangibles and non-cash equity 
compensation expense.
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. The first such quality is our prioritization of 
long-term client relationships over individual transactions, as well 
as our explicit strategic decision never to compete with our clients, 
which differentiates us from many competing capital providers. The 
second is our access to permanent capital, which enables a degree 
of flexibility and creativity in structuring new investments that we 
believe clients find valuable. The third is our ability to nimbly invest 
in smaller transaction sizes across the capital structure which results 
in more investment opportunities than competing capital providers. 
The fourth such quality is our multi-decade experience in investing 
in our target end markets, and the unique technology, policy, 
taxes, incentives and investment structures that characterize such 
markets. We believe we have demonstrated the resilience of our 
business to grow assets, earnings, and generate attractive returns 
through multiple interest rate cycles, economic cycles, and political 
administrations. Together, these qualities not only differentiate us in 
the marketplace and add strategic value to our clients but also enable 
operational and transactional efficiencies that enhance our ability to 
earn attractive risk-adjusted returns on the assets in which we invest.
We have a large and active pipeline of potential new opportunities 
that are in various stages of our underwriting process. We refer to 
potential opportunities as being part of our pipeline if we have 
determined that the project fits within our investment strategy and 
exhibits the appropriate risk and reward characteristics through 
an initial credit analysis, including a quantitative and qualitative 
assessment of the opportunity, as well as research on the relevant 
market and sponsor. Our pipeline represents transactions that could 
potentially close in the next 12 months. There can, however, be 
no assurance with regard to any specific terms of such pipeline 
transactions or that any or all of the transactions in our pipeline will 
be completed. As of December 31, 2024, our pipeline consisted 
of more than $5.5 billion in new equity, debt and real estate 
opportunities. Of our pipeline, 48% is related to BTM assets and 
25% is related to GC assets, with the remainder related to FTN. 
We fund our investments in climate solutions using a broad range of 
financing sources including corporate unsecured bonds, convertible 
bonds, non-recourse or recourse debt from banks and financial 
institutions, equity, syndications and off-balance sheet securitization 
structures. We manage our short-term liquidity needs through 
short-term commercial paper issuances and revolving credit facilities. 
In addition, certain of our debt issuances meet the environmental 
eligibility criteria for green bonds as defined by the International 
Capital Markets Association’s Green Bond Principles, which we 
believe makes our debt more attractive for many investors compared 
to such offerings that do not qualify under these principles. A further 
description of our financing activities can be found herein in the 
section titled “Financing Strategy”.
In addition, we are committed to leadership in transparent disclosure 
on sustainability, impact, and governance matters. Beginning in 
2013, we became one of the first capital providers to evaluate the 
climate impact of our investments, and we measure and report the 
efficiency with which all HASI investments avoid carbon emissions 
using CarbonCount®, our proprietary quantitative impact score 
of the avoided carbon dioxide equivalent emissions. In 2017, we 
believe we were the first U.S-based public company to commit to the 
Climate Disclosure Standards Board led initiative on implementing 
the recommendations of the Financial Stability Board’s Task Force for 
Climate-related Financial Disclosures (“TCFD”). We are a member 
of the Partnership for Carbon Accounting Financials (“PCAF”), a 
global financial industry-led partnership to implement a consistent 
and transparent disclosure framework to report carbon emissions 
and avoided emissions resulting from financed assets, and report our 
financed and avoided emissions under that framework. For further 
information on our disclosures, see the discussion in the sections 
titled “Our Investment Strategy” and “Sustainability, Impact and 
Corporate Governance” herein. We are committed to providing 
transparent disclosures on our human capital management, which 
can be found herein in the section titled “Human Capital Strategy.” 
We elected and qualified to be taxed as a REIT for U.S. federal 
income tax purposes, commencing with our taxable year ended 
December 31, 2013 through our taxable year ended December 31, 
2023. In December 2023, our Board approved our revocation of 
our REIT status effective January 1, 2024, and we are taxed as a C 
Corporation beginning with tax year 2024. We operate our business 
in a manner that permits us to maintain our exemption from registration 
as an investment company under the 1940 Act.

Market Overview
The market for sustainable infrastructure assets remains strong and 
continues to grow, supported by three major trends impacting the 
U.S. economy and energy markets, which we expect will continued 
for several years.
First is the substantial growth expected in U.S. power demand in the 
years ahead–spurred most prominently by growth in data centers, 
domestic manufacturing, and the electrification of additional sectors 
of the economy, including transportation, space heating, and 
industrial manufacturing. This outlook is underscored by a breadth 
of forecasts including McKinsey & Company (“McKinsey”) which 
estimates growth in U.S. electricity demand of more than 1,000 
terawatt-hours (TWh) between 2024 and 2030, with power 
demand from data centers alone requiring 50 gigawatts (GW) 
of new generating capacity, and requiring energy infrastructure 
investment of more than $500 billion, excluding costs for transmission 
and distribution and computer equipment within the data centers. 
Second is the heightened focus on energy prices stemming from the 
inflation shock experienced between 2022 and 2024, which we 
believe will support the desire to supply this energy demand growth 
from an “all of the above” energy strategy that includes a breadth 
of energy sources, with a specific focus on the lowest cost sources 
of electricity like solar power. 
Third is the greater awareness and appreciation of the scientific 
consensus that climate change is linked to human activities, as well 
as the substantial and growing financial costs of environmental 
disasters related to climate change. We believe this will lead 
to growing recognition of the need to satiate growth in energy 
consumption from sources with lower, if not zero, emissions, such 
as the renewable energy technologies in which we invest. We 
believe strong momentum behind these multi-year trends will lead 
to elevated demand for clean energy infrastructure assets, and 
are providing a growing set of investment opportunities that can 
generate superior risk-adjusted returns that we believe HASI’s 
business model and focus, our expertise and experience, and 
our investment and financing strategy leave it well-positioned to 
capitalize on.
Fourth is a growing focus on the need for not only greater grid 
resilience and reliability, in part due to higher load and greater 
frequency and magnitude of climate disasters, as discussed above, 
but also due to greater focus on energy national security in light of 
ongoing geopolitical uncertainty.
Our Investment Strategy
We are an investment firm dedicated to investing in, and managing 
a portfolio of, sustainable infrastructure assets. Our investment 
strategy is focused on three end markets:
• Behind-the-Meter (“BTM”): distributed renewable energy projects 
which reduce energy cost and/or usage through residential, 
commercial & industrial, and community solar power and energy 
storage deployments, as well as energy efficiency improvements 
such as heating, ventilation, and air conditioning systems (HVAC), 
lighting, energy controls, roofs, windows, building shells, and/or 
combined heat and power systems. The off-taker or counterparty 
for BTM assets may be the building owner or occupant, and our 
investment may be secured by the installed improvements or other 
real estate rights; 
• Grid-Connected (“GC”): utility-scale renewable energy projects 
that deploy cleaner energy sources, such as solar, solar-plus-
storage, and wind, to generate cleaner, lower cost energy. The 
off-takers or counterparties for GC assets may be utility, electric 
users, or participants in the wholesale electric power markets 
who have entered into contractual commitments, such as power 
purchase agreements (“PPAs”), to purchase power produced by 
a renewable energy project at a specified price with potential 
price escalators for a portion of the project’s estimated life; and 
• Fuels, Transport, and Nature (“FTN”): a range of infrastructure 
assets that are designed to reduce emissions and/or provide 
environmental benefits in projects beyond the power grid, such as 
transportation and fuels, including renewable natural gas (RNG) 
plants, transportation fleet enhancements, and ecological restoration 
projects, among others. For FTN assets, the off-takers may be oil 
and gas refiners, industrial companies, and vertically integrated 
electric utilities.
One of the defining criteria of our investment strategy is that all HASI 
investments are neutral to negative on incremental carbon emissions 
or have some other tangible environmental benefit such as reducing 
water consumption or increasing resilience to extreme weather 
events. HASI’s investment thesis is that we can generate superior 
risk-adjusted returns by investing in sustainable infrastructure assets 
based on four key premises:
• With growth in data centers, domestic manufacturing, and the 
electrification of transportation, industry, and other sectors of the 
economy expected to drive U.S. power demand higher, we expect 
clean energy assets that provide lower cost and faster speed-to-
market solutions that supply that demand will provide a growing 
number of opportunities to invest at attractive rates of return;
• With solar and wind energy, on an unsubsidized basis, 
representing the lowest cost source of electricity, according to 
Lazard Inc.’s “Levelized Cost of Energy” reports, given zero 
feedstock cost and no direct exposure to the volatility of fossil 
fuel commodity prices, clean energy should not only be in high 
demand but generate superior economic returns; 
• With scientific consensus that climate change is linked to human 
activities and resulting in a growing frequency and magnitude 
of extreme weather events and environmental disasters causing

billions of dollars of damages in the United States every year, 
assets that reduce or avoid carbon emissions can not only reduce 
potential regulatory and social costs but also substantial financial 
costs, while also providing an embedded option that may increase 
in value if regulatory authorities were to set a price on carbon 
emissions as has been done in other countries; and 
• With growing demand for energy infrastructure assets that improve 
the reliability of the electric grid and enhance national security, 
assets that improve the resilience of the grid such as distributed 
energy resources, and that do not depend on fuel imported from 
foreign sources, will provide greater value and potentially superior 
rates of return.
Our primary objective is to earn attractive risk-adjusted returns that 
sufficiently exceed our cost of capital. We believe we are able to 
generate superior risk-adjusted returns in part due to our adherence 
to a core set of investment criteria. In particular, we are focused 
primarily on investments which are:
• income-generating sustainable infrastructure assets;
• supported by underlying, long-term recurring cash flows; 
• contracted with creditworthy, incentivized off-takers;
• rely upon proven commercial technologies; and
• originated by programmatic clients
One of the primary metrics we utilize to measure our return on capital 
is a cash-on-cash internal rate of return over the life of the investment. 
In order to generate superior risk-adjusted returns, we believe it is 
important not only to pursue investments that yield attractive returns 
but also investments where risk can be sufficiently mitigated. 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 where we are 
assigned priority to collect cash flows ahead of other investors junior 
to us in the capital structure until we are able to achieve our targeted 
rate of return. In addition, we typically secure our investments with 
collateral that we are confident will support the return of our capital, 
further lowering the risk of our investments.
We make our investments via a variety of structures, including:
• equity investments in either preferred or common structures in 
unconsolidated entities;
• commercial and government receivables or securities, and
• real estate.
Our equity investments in climate solutions projects are operated 
by various renewable energy companies or by joint ventures in 
which we participate. These transactions allow us to participate in 
the cash flows associated with these projects, typically on a priority 
basis. Our debt investments in various renewable energy or other 
sustainable infrastructure projects or portfolios of projects are 
generally secured by the installed improvements, or other real estate 
rights. Our energy efficiency debt investments are usually assigned 
the payment stream from the project savings and other contractual 
rights, often using our pre-existing master purchase agreements with 
the energy service companies (“ESCOs”). We invest in land that is 
leased under long-term agreements to renewable energy projects 
where our investment returns are typically senior to most project 
costs, debt, and equity. 
Investing greater than 10% of our assets in any single investment 
requires the approval of a majority of our independent directors. 
We may adjust the mix and duration of our assets over time in order 
to allow us to manage various aspects of our Portfolio, including 
expected risk-adjusted returns, macroeconomic conditions, liquidity, 
availability of adequate financing for our assets, and our exemption 
from registration as an investment company under the 1940 Act.
We believe that our long history of climate solutions investing, the 
experience, expertise and relationships of our management team, 
the anticipated credit strength of the obligors or investees involved 
in our investments and the size and growth potential of our market, 
position us well to capitalize on our strategy.
Refer to Item 7. Management’s Discussion and Analysis of Financial 
Condition and Results of Operations—Results of Operations, for 
additional discussion on the performance of our Portfolio.
Financing Strategy
Our financing strategy is focused on lowering our cost of capital 
while also growing and diversifying our sources of capital. We 
believe we have available a broad range of financing sources 
as part of our strategy to fund our investments. We may finance 
our investments through the use of cash on hand, debt which 
may be either recourse or non-recourse and either fixed-rate or 
floating-rate, or equity, and may also finance such transactions 
through the use of off-balance sheet securitizations or syndication 
structures. When issuing debt, we generally provide the estimated 
carbon emission savings using CarbonCount. In addition, certain 
of our debt issuances meet the environmental eligibility criteria 
for green bonds as defined by the International Capital Markets 
Association’s Green Bond Principles, which we believe makes our 
debt more attractive for certain investors compared to such offerings 
that do not qualify under these principles. In 2024, we established 
CarbonCount Holdings 1 LLC (“CCH1”), a co-investment structure 
established to jointly invest $2 billion in certain eligible climate 
positive projects with an affiliate of Kohlberg Kravis Roberts & Co. 
L.P. (“KKR”). See Item 8. Financial Statements and Supplementary 
Data, Note 6 to our financial statements for further information on 
CCH1. We may consider further use of similar structures to allow us 
to expand the investments that we make or to manage our Portfolio 
diversification.
During 2024, we received a second investment grade rating from 
a major rating agency, which enabled our bonds to be included in 
investment grade bond indices. Achieving investment grade status 
has further enhanced our financing strategy by improving our access 
to capital and lowering our cost of capital.

Item 1. Business

The decision on how we finance our business is largely driven by 
our target capital structure, and by market conditions including the 
overall interest rate environment, prevailing credit spreads and the 
terms of available financing. During periods of market disruption, 
certain sources of financing may be less accessible than others which 
may impact our financing decisions. Over time, as market conditions 
change, we may use other forms of financial leverage in addition to 
these financing arrangements. Although we are not restricted by any 
regulatory requirements as to the type or amount of financial leverage 
we may use, our Board has established a target limit of our leverage 
ratio, defined as the ratio of debt to equity, of at or below 2.5 to 
1, and a target range for our percentage of fixed rate debt to total 
debt of between 75% and 100%, allowing for percentages as low 
as 70% on a short term basis if we intend to repay or swap floating 
rate borrowings in the near term. Operationally, we target a leverage 
ratio below our Board’s target limit, in the range of 1.8 to 2.0 to 1. 
See additional discussion in “Item 7. Management’s Discussion and 
Analysis of Financial Conditions and Results of Operations—Liquidity 
and Capital Resources” regarding our ongoing evaluation of our 
leverage limits and fixed-rate debt targets.
In our off-balance sheet financings, we transfer all or a portion 
of an investment to a securitization trust in exchange for cash 
and/or residual interests in the trust, and in some cases, ongoing 
fees. The availability of securitization counterparties has remained 
high throughout various market cycles due to investor demand for 
high credit quality, long-term climate-positive investments. We 
may arrange such securitizations of loans or other assets prior 
to originating the transaction and thus avoid exposure to credit 
spread, interest rate and funding risks. We also typically manage 
and service these assets in exchange for fees. We may also use 
other funds or structures such as CCH1 where institutional investors 
purchase all or a portion of the economics of the transaction and 
where we may receive upfront or ongoing fees for managing 
the assets. We periodically provide other services, including 
arranging financings that are held on the balance sheets of 
other investors and advising various companies with respect to 
structuring investments. 
Refer to Item 7. Management’s Discussion and Analysis of Financial 
Conditions and Results of Operations—Liquidity and Capital 
Resources, for additional discussion on our financings and our 
ratios and Item 8. Financial Statements and Supplementary Data,

on the types and amounts of our financing activities.
Human Capital Strategy
An emphasis on a durable social fabric, including engaged, 
collaborative, and fairly compensated staff, is an important factor 
in our financial success. Our culture is focused on hiring and 
retaining highly talented employees with diverse perspectives and 
empowering them to create value for our stockholders, and our 
success is dependent on employee understanding of and investment 
in their role in that value creation. Our employees are responsible 
for upholding our vision, purpose, and values. 
Our employees are typically engaged in our mission of sustainability 
and we believe this engagement improves their performance, as 
well as our employee recruitment and retention. Our chief executive 
officer periodically leads employee meetings intended to reinforce 
the importance of our mission and regularly meets with small groups 
of employees to receive their feedback on our business. We also 
meet no less than quarterly as a company to provide information 
to employees on our strategy, mission, and financial results. We 
continuously evaluate our employees’ level of engagement through 
in-person or remote meetings and through formal surveys or similar 
tools administered on a periodic basis.
We adhere to a blended learning approach with the understanding 
that our people learn from experiences (on the job and outside of 
work), from other people (mentors or supportive managers), and 
from formal learning and training programs. We run a periodic 
education series that includes internal and external speakers 
presenting topics of interest that are relevant to our employees. We 
provide multiple learning solutions that cover a wide range of areas 
such as leadership skills, financial knowledge, technology training, 
presentation skills, and training intended to support an inclusive 
environment for all. We also support the pursuit of advanced 
certifications and degrees in areas including business, science 
and engineering, and liberal and fine arts and employ formal and 
informal coaching arrangements. 
We care about our employees’ employment experience and 
recognize them as individuals who are motivated in different ways. 
Managers hold performance conversations with their employees 
on a periodic basis to ensure they receive adequate performance 
feedback, and to allow managers to both obtain insight into how to 
support the development of their staff and to ensure that performance 
expectations are clear and aligned with the overarching objectives 
of the Company. We also provide continuous dialogue in between 
these formal touchpoints. 
We believe we provide attractive benefits that promote the health 
of our employees and their families and design compelling job 
opportunities, aligned with our mission, in an energizing work 
environment. We also encourage our employees to continue to 
develop in their careers, including by obtaining advanced degrees 
or professional certifications. We compensate our employees 
according to our fair remuneration policies and believe in paying 
for performance. Therefore, employees typically receive a portion 
of their compensation in the form of annual bonuses as well as 
equity grants which are both tied in part to the Company’s financial 
performance. In addition to competitive base salaries, cash bonuses, 
and equity participation for most employees, we are committed 
to continuously evaluating and ensuring the competitiveness of 
our benefits offerings so that we meet the various needs of our 
employees and their families. Despite a healthcare environment 
that is facing rising costs, we continue to pay substantially all of the 
cost of our employees’ healthcare insurance. Further, in addition to 
what we believe to be market total rewards benefits, we provide 
additional benefits, such as employee assistance programs, back-up 
childcare solutions, and a tuition reimbursement program.

We take a values-driven, broad view of diversity, equity, and 
inclusion for all. We believe that fostering an internal culture of 
belonging that allows people of all backgrounds to flourish lends 
itself to the highest levels of company performance and facilitates 
the attraction and retention of best-in-class talent. Employees who 
hold divergent opinions are encouraged to voice their views. We 
track and report internally on key talent metrics including workforce 
demographics, critical role pipeline data, and engagement and 
inclusion indices.
Decisions regarding staffing, selection, and promotions are 
made on the basis of individual qualifications related to the 
requirements of the position. We endeavor to select qualified 
individuals from a diverse pool of candidates derived from broad 
outreach efforts when we are recruiting. We are committed to the 
development and/or promotion of highly-qualified personnel from 
all demographics including women, people of color and other 
recognized groups for management and Board positions. 
Our policy is “equal pay for equal work” in compliance with 
applicable state law. Compensation for our employees is based 
upon experience, seniority, educational attainment, and individual 
contribution and company performance against goals. 
As of December 31, 2024, we employed 158 people. We intend 
to hire additional business professionals as needed to assist in 
the implementation of our business strategy. Refer to “Item 7. 
Management’s Discussion and Analysis of Financial Condition 
and Results of Operations - Results of Operations – Human 
Capital Metrics” for discussion of metrics related to our Human 
Capital Strategy.
Sustainability, Impact and Corporate Governance
We own and invest in a diversified portfolio of climate solutions 
projects focused on reducing or mitigating the impacts of climate 
change. Under the direction of our chief executive officer and our 
Board, we are focused on achieving a high level of environmental 
and social responsibility and strong corporate governance. The 
Nominating, Governance and Corporate Responsibility Committee 
of our Board is responsible for our oversight of sustainability, 
impact, and governance matters, including related policies and 
communications. Additionally, we have a committee of employees 
from across our organization that is focused on implementing 
sustainability and impact strategies and policies and reports 
directly to our chief executive officer. Annually we publish a report 
that illustrates our progress on these matters. We are a signatory 
to the United Nations Global Compact, an initiative focused on 
responsible business practices related to human rights, labor, the 
environment and anti-corruption.
Sustainability. Our business and business strategy are focused on 
addressing climate change, in part through the reduction of carbon 
emissions that have been scientifically linked to climate change. 
As described under “Investment Strategy”, we quantify the carbon 
impact of each of our investments. In addition, we operate our 
business in a manner intended to reduce our own environmental 
impact, including by purchasing renewable energy credits to mitigate 
the impact of our office operations, encouraging recycling and 
composting, and offering clean transportation employee incentives 
for electric and hybrid vehicles. We have also adopted policies 
focused on minimizing the environmental impact of our operations. 
In 2021, we established targets for our transition to net-zero carbon 
emissions by 2050 using the foundational framework developed 
by the Science Based Targets Initiative.
Impact. We recognize that the effects of pollution, environmental 
degradation, increased climate-fueled extreme weather events, 
and the economic transition away from fossil fuels fall most heavily 
on certain communities in our society, especially rural communities 
and communities of color. We know that the effects of climate 
change are already disproportionately impacting disadvantaged 
communities, and these adverse outcomes will be exacerbated if we 
do not eliminate harmful greenhouse gas emissions. Equally so, we 
acknowledge the legacy of discriminatory policies in creating and 
perpetuating this imbalance. We believe that the energy transition 
presents an opportunity to address these disparities.
These principles inform our process for underwriting investments, 
our engagement with business partners, our human capital strategy, 
philanthropy, and policy advocacy efforts. We established the HASI 
Foundation to provide cash and in-kind support to programs which 
provide climate solutions investments and career opportunities for 
those from disadvantaged communities, as well as organizations 
across our local region that seek to strengthen the social fabric and 
promote economic and climate resiliency.
Governance. We are focused on achieving best-in-class corporate 
governance practices to help ensure that our team will operate in 
a manner consistent with our organizational mission and deliver 
attractive risk-adjusted returns. Our corporate governance 
philosophy is based on maintaining a close alignment of our interests 
with those of our stakeholders. Notable features of our corporate 
governance structure include the following:
• our Corporate Governance Guidelines provide for a majority vote 
policy for the election of directors pursuant to which any nominee 
who receives a greater number of votes “withheld” from his or her 
election than votes “for” such election shall promptly tender his 
or her resignation to our Board for their consideration to accept 
or reject such resignation;
• our Board is not staggered, with each of our directors subject to 
re-election annually;

(“NYSE”) corporate governance listing standards and 
Rule 10A-3 under the Exchange Act;
• we have a lead independent director of our Board that convenes 
and chairs executive sessions of the independent directors to 
discuss certain matters without management or the chairman 
present;
• we have separated the executive chairman and chief executive 
officer roles; 
• three of our directors qualify as an “audit committee financial 
expert” as defined by the Securities and Exchange Commission 
(the “SEC”);
• four of our directors (including our lead independent director) are 
women and two of our directors are people of underrepresented 
ethnicity constituting 40% and 20% respectively, of our Board in 
furtherance of our board diversity policy;
• a target retirement age of 75 has been established for our directors;
• we have an active stockholder outreach program, including 
providing stockholders the right to vote on an advisory basis on 
the fairness of the remuneration of executives;
• our Board members and named executive officers are required 
to maintain certain levels of stock ownership in our company 
ranging between three and six times their base salary or retainer, 
depending on position; 
• we have a Clawback Policy that provides for the possible 
recoupment of performance or incentive-based compensation 
in the event of an accounting restatement due to material 
noncompliance by us with any financial reporting requirements 
under the securities laws (other than due to a change in applicable 
accounting methods, rules or interpretations); and
• stockholders have the ability to amend the Company’s bylaws by 
the affirmative vote of the holders of a majority of the outstanding 
shares of our common stock pursuant to a binding proposal 
submitted by a stockholder.
In order to foster the highest standards of ethics and conduct in 
all business relationships, we have adopted a Code of Business 
Conduct and Ethics policy (the “Code of Conduct”). This policy 
covers a wide range of business practices and procedures 
and applies to our officers, directors, employees, agents, 
representatives, and consultants. In addition, we have implemented 
whistleblowing procedures designed to facilitate the report of 
accounting and auditing matters as well as Code of Conduct 
matters (the “Whistleblower Policy”) that sets forth procedures by 
which any Covered Persons (as defined in the Whistleblower Policy) 
may report, on a confidential basis, concerns regarding, among 
other things, any questionable or unethical accounting, internal 
accounting controls or auditing matters with our Audit Committee as 
well as any potential Code of Conduct or ethics violations with our 
Nominating, Governance and Corporate Responsibility Committee 
or our Chief Legal Officer.
We have adopted a Statement of Corporate Policy Regarding 
Equity Transactions that governs the process to be followed in the 
purchase or sale of our securities by any of our directors, officers, 
employees and consultants and prohibits any such persons from 
buying or selling our securities on the basis of material nonpublic 
information, and also prohibits our directors and officers from 
hedging equity securities of the Company, holding such securities 
in a margin account or pledging such securities as collateral for a 
loan. We review all of these policies on a periodic basis with our 
employees. See Exhibit 19.1 to this Form 10-K for these policies. 
Our business is managed by our leadership team, subject to the 
supervision and oversight of our Board. Our directors stay informed 
about our business by attending meetings of our Board and its 
committees and through supplemental reports and communications. 
We believe in transparent reporting relating to sustainability and 
impact matters because we believe such reporting improves the 
understanding of our financial results. As discussed in the “Investment 
Strategy” section above, we quantify the environmental impact of 
every transaction we execute through the application of CarbonCount.

originated in 2024 can be found in “Item 7. Management’s Discussion 
and Analysis of Financial Condition and Results of Operations — 
Results of Operations — Environmental Metrics”.
We continue to implement the TCFD recommendations, and the 
recommended disclosures will be included in our Sustainability and 
Impact Report, which is not furnished or filed with the SEC and is 
not deemed to be incorporated by reference into this document. 
In addition to the above environmental reporting initiatives, beginning 
in 2022, we report our corporate emissions under PCAF, a voluntary 
global financial industry-led partnership to implement a consistent 
and transparent disclosure framework to report carbon emissions and 
avoided emissions resulting from financed assets. We also disclose 
metrics related to our Human Capital Strategy. Refer to “Item 7. 
Management’s Discussion and Analysis of Financial Condition and 
Results of Operations — Results of Operations — Human Capital 
Metrics”. When issuing debt, we generally provide the estimated 
carbon emission savings using CarbonCount, and in some instances 
are able to achieve better borrowing rates by achieving certain 
CarbonCount scores. Certain of our debt issuances have been 
evaluated to determine that they meet the environmental eligibility 
criteria for green bonds as defined by the International Capital 
Markets Association’s Green Bond Principles.

Competition
We compete against a number of parties, including banks, 
private equity, hedge or infrastructure investment funds, insurance 
companies, mutual funds, institutional investors, investment banking 
firms, specialty finance companies, utilities, independent power 
producers, project developers, pension funds, governmental bodies, 
private credit platforms, green banks, and public entities established 
to own infrastructure assets and other entities.
We compete primarily on the basis of service, price, structure and 
flexibility as well as the breadth and depth of our expertise. We 
may at times compete and at other times partner or work as a 
participant with alternative financing sources. The opportunities in 
alternative investment and increasing investor acceptance of the 
climate solutions market has increased the level of competition we 
experience. We may also encounter competition in the form of 
potential customers or our origination partners electing to use their 
own capital rather than engaging us as an outside capital provider. 
In addition, we may also face competition based on technological 
developments that reduce demand for electricity, increase power 
supplies through existing infrastructure or that otherwise compete 
with climate solutions projects in which we have invested. We 
believe that a significant part of our competitive advantage is our 
management team’s experience and industry expertise. 
For additional information concerning these competitive risks, see 
“Item 1A. Risk Factors—We operate in a competitive market, which 
may impact the terms of the investments we make.”

Item 1A. Risk Factors
Our business and operations are subject to a number of risks and uncertainties, the occurrence of which could adversely affect our business, 
financial condition, consolidated results of operations and ability to make distributions to stockholders and could cause the value of our capital 
stock to decline. We may refer to the energy efficiency, renewable energy and the other sustainable infrastructure projects or markets in which 
we participate collectively as climate solutions projects or the industry. Please also refer to the sections entitled “Forward-Looking Statements” 
and “Risk Factor Summary”.
Risks Related to Our Business and Our Industry
If the cost of energy generated by traditional sources 
of energy declines from present levels, demand for the 
projects in which we invest may decline.
Many traditional sources of energy such as coal, petroleum-based 
fuels and natural gas can be influenced by the price of underlying or 
substitute commodities. Such prices, which have decreased and may 
continue to decrease, may reduce the demand for energy efficiency 
projects or other projects, including renewable energy facilities, that 
do not rely on fossil fuel energy sources. For example, low natural 
gas prices may reduce the demand for projects like renewable 
energy that can substitute for natural gas. Low natural gas prices 
also typically adversely affect both the price available to renewable 
energy projects under future power sale agreements and the price of 
the electricity the projects sell on either a forward or a spot-market 
basis. Further, as has occurred in the past, technological progress 
in electricity generation, storage or in the production of traditional 
fuels or the discovery of large new deposits of traditional fuels 
could reduce the cost of energy generated from those sources and 
consequently reduce the demand for the types of projects in which 
we invest, which could harm our new business origination prospects 
as well as the value of our existing Portfolio. In addition, volatility 
in commodity prices, including energy prices, may cause building 
owners and other parties to be reluctant to commit to projects for 
which repayment is based upon a fixed monetary value for energy 
savings that would not decline if the price of energy declines. Any 
resulting decline in demand for our investments or the price that 
industry participants receive for the sale of fossil fuel could adversely 
impact our operating results.
If the market for various types of climate solutions 
projects or the investment techniques related to 
such projects do not develop as we anticipate, 
new business generation in this target area may be 
adversely impacted.
The market for various types of climate solutions projects is emerging 
and rapidly evolving, leaving their future success uncertain. If some 
or all market segments or investing techniques prove unsuitable for 
widespread commercial deployment or if demand for such projects 
or techniques fail to grow sufficiently, the demand for our capital 
may decline or develop more slowly than we anticipate. Many 
factors will influence the widespread adoption and demand for 
such projects and investing techniques, including general and local 
economic conditions, commodity prices of fossil fuel energy sources, 
the cost and availability of energy storage, the cost-effectiveness 
of various projects and techniques, performance and reliability of 
such technologies compared to conventional power sources and 
technologies, and the extent of government subsidies and regulatory 
developments. Any changes in the markets, products, technologies, 
financing techniques, or the regulatory environment could adversely 
impact the demand or financial performance for such projects and 
our investments.
Some projects in which we invest rely on net metering 
and related policies to improve project economics 
which if reduced could impact repayment of our 
investments or the return on our assets.
There has been a nationwide increase in distributed generation which 
has prompted discussions among policy makers and regulators 
regarding ways to both better integrate distributed energy resources 
into the electric grid and how to compensate distributed generators. 
Many states have a regulatory policy known as net energy metering, 
or net metering. Net metering typically allows some project customers 
to interconnect their on-site solar or other renewable energy systems to 
the utility grid and offset their utility electricity purchases by receiving 
a bill credit at the utility’s retail rate for the amount of energy in excess 
of their electric usage that is generated by their renewable energy 
system and is exported to the grid. At the end of the billing period, the 
customer simply pays for the net energy used or receives a credit at the 
retail rate if more energy is produced than consumed. Net metering 
policies are under review or have been limited or amended in a 
number of states. The ability and willingness of customers to pay for 
renewable energy systems that benefit from net metering rules may be 
reduced if net metering rules are eliminated or their benefits reduced, 
which may also impact our returns on such systems.
Existing electric utility industry regulations, and changes 
to regulations, may present technical, regulatory and 
economic barriers to the purchase and use of renewable 
energy and energy efficiency systems that may significantly 
reduce demand for systems and projects in which we invest 
or may adversely affect the profitability of such projects.
Federal, state and local government regulations and policies 
concerning the electric utility industry, and internal policies and 
regulations promulgated by electric utilities, heavily influence the 
14
HASI Form 10-K
Part I
Item 1A. Risk Factors

market for electricity products and services. These regulations and 
policies often relate to electricity pricing and the interconnection 
of customer-owned electricity generation. In the United States, 
governments and utilities continuously modify these regulations 
and policies. These regulations and policies could deter customers 
from purchasing energy efficiency and renewable energy systems. 
For example, Federal Energy Regulatory Commission (“FERC”) 
conducted its own review of grid resiliency and the functioning of 
electricity markets and has made, and could continue to make, 
changes to policies and regulations related to the function of the 
electricity markets and grid resiliency which may negatively impact 
the use of renewable energy or encourage the use of fossil fuel energy 
over renewable energy. This could result in a significant reduction in 
the potential demand for such systems. Utilities commonly charge 
fees to larger, industrial customers for disconnecting from the electric 
grid or for having the capacity to use power from the electric grid for 
back-up purposes. In addition, there is an increasing trend towards 
initiating or increasing fixed fees for users to have electricity service 
from a utility. These fees could increase our customers’ cost to use 
energy efficiency and renewable energy systems not supplied by the 
utility and make them less desirable, thereby harming our business, 
prospects, financial condition and results of operations. In addition, 
any changes to government or internal utility regulations and policies 
that favor electric utilities could reduce competitiveness and cause a 
significant reduction in demand for systems in which we invest.
Further, certain climate solutions projects in which we invest may be 
“qualifying facilities” that are exempt from rate regulation as public 
utilities by FERC under the Federal Power Act, (the “FPA”). FERC 
regulations under the FPA confer upon these qualifying facilities key 
rights to interconnection with local utilities and can entitle such facilities 
to enter into PPAs with local utilities, from which the qualifying facilities 
benefit. Changes to these U.S. federal laws and regulations could 
increase the regulatory burdens and costs and could reduce the 
revenue of the project. In addition, modifications to the pricing policies 
of utilities could require climate solutions projects to achieve lower 
prices in order to compete with the price of electricity from the electric 
grid and may reduce the economic attractiveness of certain energy 
efficiency measures. To the extent that the projects in which we invest 
are subject to rate regulation, the project owners will be required to 
obtain FERC acceptance of their rate schedules for wholesale sales 
of energy, capacity and ancillary services. Any adverse changes in 
the rates project owners are permitted to charge could negatively 
impact the repayment of our investments, or the return on our assets.
In addition, the operation of, and electrical interconnection for, 
our climate solutions projects may be subject to U.S. federal, state 
or local interconnection and federal reliability standards, some of 
which are set forth in utility tariffs. These standards and tariffs specify 
rules, business practices and economic terms to which the projects in 
which we invest are subject and that may impact a project’s ability 
to deliver the electricity it produces or transports to its end customer. 
The tariffs are drafted by the utilities and approved by the utilities’ state 
and U.S. federal regulatory commissions. These standards and tariffs 
change frequently and it is possible that future changes will increase 
our administrative burden or adversely affect the terms and conditions 
under which the projects render services to their customers.
Under certain circumstances, we may also be subject to the 
reliability standards of the North American Electric Reliability 
Corporation. If project owners fail to comply with the mandatory 
reliability standards, they could be subject to sanctions, including 
substantial monetary penalties, which could also raise credit risks 
for, or lower the returns available from, the project companies in 
which we invest.
These various regulations may also limit the transferability or sale 
of renewable energy projects and any such limits could negatively 
impact our returns from such projects.
We are subject to risks related to our sustainability and 
governance activities and disclosures.
Our sustainability and governance strategy and practices and the 
level of transparency with which we are approaching them are 
foundational to our business and expose us to several risks. We may 
fail or be unable to fully achieve one or more of our sustainability 
and governance goals due to a range of factors within or beyond 
our control, or we may adjust or modify our goals in light of new 
information, adjusted projections, or a change in business strategy, 
which could negatively impact our reputation and our business. 
A failure to or perception of a failure to disclose metrics and set goals 
that are rigorous enough or in an acceptable format, a failure to 
appropriately manage selection of goals, a failure to or perception of 
a failure to make appropriate disclosures, stockholder perception of a 
failure to prioritize the “correct” sustainability and governance goals, 
or an unfavorable sustainability and governance-related rating by a 
third party, could negatively impact our reputation and our business. 
The environmental, social, and governance (“ESG”) standards, 
norms, or metrics, are constantly evolving. In recent years “anti-ESG” 
sentiment has gained momentum across the U.S., with several states 
and Congress having proposed or enacted “anti-ESG” policies, 
legislation, or initiatives or issued related legal opinions, and the 
President having recently issued an executive order opposing 
diversity equity and inclusion (“DEI”) initiatives in the private sector. 
If we do not successfully manage expectations across varied 
stakeholder interests, such anti-ESG and anti-DEI-related policies, 
legislation, initiatives, litigation, legal opinions, and scrutiny could 
result in us facing additional compliance obligations, becoming 
the subject of investigations and enforcement actions, or sustaining 
reputational harm. 
Certain data we utilize in our CarbonCount or similar metric 
calculations is prepared by third parties or receives limited assurance 
from and/or verification by third parties and may undergo a less 
rigorous review process than assurance sought in connection with 
more traditional audits and such review process may not identify errors 
and may not protect us from potential liability under the securities 
laws. If errors are identified, our reputation and our business could be 
negatively impacted. If we were to seek more extensive assurance or 
attestation with respect to such sustainability and governance metrics, 
15
HASI Form 10-K
Part I
Item 1A. Risk Factors

we may be unable to obtain such assurance or attestation or may 
face increased costs related to obtaining and/or maintaining such 
assurance or attestation. Our business could be negatively impacted if 
any of our disclosures, including our CarbonCount or similar metrics, 
reporting to third-party standards, or reporting against our goals, are 
inaccurate, perceived to be inaccurate, or alleged to be inaccurate.
We operate in a competitive market, which may impact 
the terms of our investments.
We compete against a number of parties who may provide alternatives 
to our investments including, among others, a wide variety of financial 
institutions, government entities and energy industry participants. 
Increasing investor acceptance of the climate solutions market has 
increased the level of competition we experience. We also encounter 
competition in the form of potential customers or our origination 
partners electing to use their own capital rather than engaging an 
outside provider such as us. Some of our competitors are significantly 
larger than we are, have access to greater capital and other resources 
than we do and may have other advantages over us. In addition, 
some of our competitors have higher risk tolerances or different risk 
assessments, which allow those competitors to consider a wider variety 
of investments and establish more relationships than we can. Further, 
many of our competitors are not subject to the operating constraints 
associated with maintenance of an exemption from the 1940 Act. 
These characteristics could allow our competitors to consider a wider 
variety of opportunities, establish more relationships and offer better 
pricing and more flexible structuring than we can offer. We may lose 
business opportunities if we do not match our competitors’ pricing, 
terms and structure. If we match our competitors’ pricing, terms and 
structure, we may not be able to achieve acceptable risk-adjusted 
returns on our assets or we may be forced to bear greater risks of 
loss. The increase in the number or the size of our competitors in this 
market has resulted, and could continue to result, in less attractive 
terms on our investments or the need to accept a higher level of risks 
associated with our investments. As a result, competitive pressures we 
face could have a material adverse effect on our business, financial 
condition and results of operations.
Our business depends in part on U.S. federal, state 
and local government policies, and a decline in the 
level of government support could harm our business.
The projects in which we invest typically depend in part on various 
U.S. federal, state or local governmental policies and incentives 
that support or enhance project economic feasibility. Such policies 
may include governmental initiatives, laws and regulations designed 
to reduce energy usage and impact the use of renewable energy 
or the investment in and the use of climate solutions, including the 
Infrastructure Investment and Jobs Act and the Inflation Reduction 
Act. U.S. federal policies and incentives include, for example, 
tax credits, tax deductions, bonus depreciation, federal grants 
and loan guarantees and energy market regulations. State and 
local governments policies and incentives include, for example, 
renewable portfolio standards (“RPS”), feed-in tariffs, other tariffs, 
tax incentives and other cash and non-cash payments.
Governmental agencies, commercial entities and developers 
of climate solutions projects frequently depend on these policies 
and incentives to help defray the costs associated with, and to 
finance, various projects. Government regulations also impact the 
terms of third-party financing provided to support these projects, 
including through energy savings performance contracts. If any of 
these government policies, incentives or regulations are adversely 
amended, delayed, eliminated, reduced, retroactively changed or 
not extended beyond their current expiration dates, or there is a 
negative impact from the recent federal law changes or proposals, 
the operating results of the projects we finance and the demand 
for, and the returns available from, the investments we make may 
decline, which could harm our business.
U.S. federal, state and local government entities are 
major participants in, and regulators of, the energy 
industry, and their actions could be adverse to our 
project companies or our company.
The projects we invest in are subject to substantial regulation by U.S. 
federal, state and local governmental agencies. For example, many 
projects require government permits, licenses, concessions, leases 
or contracts. Government entities, due to the wide-ranging scope of 
their authority, have significant leverage in setting their contractual 
and regulatory relationships with third parties. In addition, government 
permits, licenses, concessions, leases and contracts are generally 
very complex, which may result in periods of non-compliance, or 
disputes over interpretation or enforceability. If the projects in which 
we invest fail to obtain or comply with applicable regulations, permits, 
or contractual obligations, they could be prevented from being 
constructed or subjected to monetary penalties or loss of operational 
rights, which could negatively impact project operating results and 
the returns on our assets. In addition, government counterparties 
also may have the discretion to change or increase regulation of 
project operations, or implement laws or regulations affecting project 
operations, separate from any contractual rights they may have. These 
actions could adversely impact the efficient and profitable operation 
of the projects in which we invest.
Contracts with government counterparties that support the projects 
in which we invest may be more favorable to the government 
counterparties compared to commercial contracts with private 
parties. For example, a lease, concession or general service 
contract may enable the government to modify or terminate the 
contract without requiring the payment of adequate compensation. 
Typically, our contracts with government counterparties contain 
termination provisions, including prepayment amounts. In most 
cases, the prepayment amounts provide us with amounts sufficient to 
repay the financing we have provided but may be less than amounts 
that would be payable under “make whole” provisions customarily 
found in commercial lending arrangements.
16
HASI Form 10-K
Part I
Item 1A. Risk Factors

Government entities may also suspend or debar contractors from 
doing business with the government or pursue various criminal 
or civil remedies under various government contract regulations. 
They may also issue new government contracts or fail to extend 
existing government contracts. Our ability to originate new assets 
could be adversely affected if one or more of the ESCOs or other 
origination sources with whom we have relationships are suspended 
or debarred or fail to win new, or renew existing, contracts.
A change in the fiscal health, level of appropriations or 
budgets of U.S. federal, state and local governments 
could reduce demand for our investments.
Although our energy efficiency investments do not normally require 
additional governmental appropriations to cover repayment due to 
the energy and operating savings derived from the newly installed 
equipment and systems, a significant decline in the fiscal health, level 
of appropriations or budgets of government customers may make it 
difficult for them to remain current on existing payment obligations or 
undesirable to enter into new energy efficiency improvement projects. 
Alternatively, some government entities may choose to provide 
appropriations or other credit support for climate solutions projects, 
which would negatively impact the use of private capital such as ours. 
This could have a material and adverse effect on the return of and 
return on our investments for existing projects and on our ability to 
originate new assets. Moreover, other changes in resources available 
to governments may also impact their willingness to undertake energy 
efficiency projects. For example, an increase in money set aside for 
government expenditures for energy efficiency projects may reduce 
demand for our investments.
In addition, to the extent we make investments that involve direct 
appropriations, we will depend on approval of the necessary 
spending for the projects. The repayment of the investment, or the 
return on our asset, could be adversely affected if appropriations for 
any such projects are delayed or terminated.
Risks Related to Our Assets and Projects in Which We Invest
Changes in interest rates could adversely affect 
the value of our assets and negatively affect our 
profitability.
Interest rates are highly sensitive to many factors, including 
governmental monetary and tax policies, domestic and international 
economic and political considerations and other factors beyond our 
control. Many of our assets pay a fixed rate of interest or provide 
a fixed preferential return.
With respect to the projects in which we invest, increases in interest 
rates, have caused, and in general, may in the future cause: (1) project 
owners to be less interested in borrowing or raising equity and thus 
reduce the demand for our investments; (2) the interest expense 
associated with the project’s borrowings to increase; (3) the market 
value of the project’s fixed rate or fixed return assets to decline; and 
(4) the market value of any of the project’s fixed-rate interest rate 
swap agreements to increase. Decreases in interest rates, in general, 
may over time cause: (1) project owners to be more interested in 
borrowing or raising equity thus increase the demand for our assets; 
(2) prepayments on our assets, to the extent allowed, to increase; 
(3) the interest expense associated with the project’s borrowings to 
decrease; (4) the market value of the project’s fixed rate or fixed return 
assets to increase; and (5) the market value of any fixed-rate interest 
rate swap agreements to decrease. Adverse developments resulting 
from changes in interest rates could have a material adverse effect on 
our business, financial condition and results of operations.
The lack of liquidity of our assets may adversely affect 
our business, including our ability to value our assets.
Volatile market conditions could significantly and negatively impact 
the liquidity of our assets. Illiquid assets typically experience greater 
price volatility, as a ready market does not exist, and can be more 
difficult to value. In addition, validating third-party pricing for illiquid 
assets may be more subjective than more liquid assets. The illiquidity 
of our assets may make it difficult for us to sell such assets if the need 
or desire arises. In addition, if we are required to liquidate all or 
a portion of our Portfolio quickly, we may realize significantly less 
than the value at which we have previously recorded our assets. To 
the extent that we utilize leverage to finance our investments that 
are or become illiquid, the negative impact on us related to trying 
to sell assets in a short period of time for cash could be greatly 
exacerbated. As a result, our ability to vary our Portfolio in response 
to changes in economic and other conditions may be relatively 
limited, which could adversely affect our results of operations and 
financial condition.
Some of the assets in our Portfolio may be recorded at 
fair value and, as a result, there could be uncertainty 
as to the value of these assets. Further, we may 
experience a decline in the fair value of our assets.
Our investments are not publicly traded. The fair value of assets 
that are not publicly traded may not be readily determinable. In 
accordance with GAAP, we record certain of our assets at fair value, 
which may include unobservable inputs. Because such valuations 
are subjective, the fair value of these assets may fluctuate over short 
periods of time and our determinations of fair value may differ 
materially from the values that would have been used if a ready 
market for these assets existed. The value of our common stock 
could be adversely affected if our determinations regarding the 
fair value of these assets were materially higher than the values that 
we ultimately realize upon their disposal. Additionally, our results 
of operations for a given period could be adversely affected if 
our determinations regarding the fair value of these assets were 
materially higher than the values that we ultimately realize upon 
17
HASI Form 10-K
Part I
Item 1A. Risk Factors

their disposal. The valuation process can be particularly challenging 
during periods when market events make valuations of certain assets 
more difficult, unpredictable and volatile.
A decline in the fair market value of any asset we carry at fair value, 
may require us to reduce the value of such assets under GAAP. In 
addition, our other financial assets are subject to an impairment 
assessment that could result in adjustments to their carrying values. 
Upon the subsequent disposition or sale of such assets, we could 
incur future losses or gains based on the difference between the 
sale price received and adjusted value of such assets as reflected 
on our balance sheet at the time of sale.
Our projects and their obligors are exposed to 
an increase in climate change or other change in 
meteorological conditions, which could have an 
impact on electric generation, revenue, insurance costs 
or the ability of the projects or their obligors to honor 
their contract obligations, all of which could adversely 
affect our business, financial condition and results of 
operations and cash flows.
The electricity produced and revenues generated by a renewable 
electric generation facility are highly dependent on suitable 
weather conditions, which are beyond our control. Components 
of renewable energy systems, such as turbines, solar panels 
and inverters, could be damaged by natural disasters or severe 
weather, including extreme temperatures, wildfires, hurricanes, 
hailstorms or tornadoes. Furthermore, the potential physical impacts 
of climate change may impact our projects, including the result of 
changes in weather patterns (including floods, tsunamis, drought, 
mudslides, and rainfall levels), wind speeds, water availability, 
storm patterns and intensities, and temperature levels. The projects 
in which we invest will be obligated to bear the expense of 
repairing the damaged renewable energy systems and replacing 
spare parts for key components and insurance may not cover the 
costs or the lost revenue. Natural disasters or unfavorable weather 
and atmospheric conditions, such as extreme cold temperatures or 
extreme events of rain, flooding, and mudslides, could impair the 
effectiveness of the renewable energy assets, reduce their output 
beneath their rated capacity, require shutdown of key equipment 
or impede operation of the renewable energy assets, which could 
adversely affect our business, financial condition and results of 
operations and cash flows. Sustained unfavorable weather could 
also unexpectedly delay the installation of renewable energy 
systems, which could result in a delay in our investing in new 
projects or increase the cost of such projects. The resulting effects 
of climate change can also have an impact on the cost of, and 
the ability of a project to obtain, adequate insurance coverage 
to protect against related losses. 
We typically base our investment decisions with respect to each 
renewable energy facility on the findings of studies conducted on-
site prior to construction or based on historical conditions at existing 
facilities. However, actual climatic conditions at a facility site may 
not conform to the findings of these studies. Even if an operating 
project’s historical renewable energy resources are consistent with the 
long-term estimates, the unpredictable nature of weather conditions 
often results in daily, monthly and yearly material deviations from 
the average renewable resources anticipated during a particular 
period. Therefore, renewable energy facilities in which we invest 
may not meet anticipated production levels or the rated capacity 
of the generation assets, which could adversely affect our business, 
financial condition and results of operations and cash flows.
In addition, many of the project’s end-customers are large entities 
with wide ranging activities. A climate related event in a non-related 
part of the business could have a material adverse impact on the 
financial strength of such end-customer and their ability to honor 
their contractual obligations which could negatively impact on 
revenue and the cash flow of the project and our business. 
The preparation of our financial statements, including 
provision for loan losses, involves use of estimates, 
judgments and assumptions, and our financial 
statements may be materially affected if our estimates 
prove to be incorrect.
Financial statements prepared in accordance with GAAP require 
the use of estimates, judgments and assumptions that affect the 
reported amounts. Different estimates, judgments and assumptions 
reasonably could be used that would have a material effect on 
the financial statements, and changes in these estimates, judgments 
and assumptions are likely to occur from period to period in the 
future. Significant areas of accounting requiring the application of 
management’s judgment include but are not limited to determining 
the fair value of our assets.
These estimates, judgments and assumptions are inherently uncertain, 
and, if they prove to be wrong, then we face the risk that charges 
to income will be required. Any charges could significantly harm 
our business, financial condition, results of operations and the price 
of our securities. See Management’s Discussion and Analysis of 
Financial Condition and Results of Operations—Critical Accounting 
Policies and Use of Estimates for a discussion of the accounting 
estimates, judgments and assumptions that we believe are the most 
critical to an understanding of our business, financial condition and 
results of operations. 
Further, our provision for loan losses is evaluated on a quarterly 
basis. The determination of our provision for loan losses requires us 
to make certain estimates and judgments, which may be difficult to 
determine. Our estimates and judgments are based on a number 
of factors and may not be correct. If our estimates or judgments are 
incorrect, our results of operations and financial condition could be 
adversely impacted. See Management’s Discussion and Analysis of 
Financial Condition and Results of Operations—Critical Accounting 
Policies and Use of Estimates for a discussion of the accounting 
estimates, judgments and assumptions that we believe are the most 
critical to our provision of loan losses.

We rely on our project sponsors for financial reporting 
related to our project companies, and our financial 
statements may be materially affected if the financial 
reporting related to our project companies proves to 
be incorrect.
We have equity investments in climate solutions project companies 
that we account for under the equity method of accounting, which 
requires us to rely on the project sponsor for the reporting of the 
financial results of those project companies, including in some 
instances the allocation of earnings under the hypothetical liquidation 
at book value (“HLBV”) method. The HLBV method involves complex 
judgments around the interpretation of legal provisions governing 
liquidation of the entity in which we are invested. To the extent the 
reporting inclusive of these HLBV allocations we are provided is 
incorrect, our financial results reported using that information may 
be incorrect.
Our investments are subject to delinquency, 
foreclosure and loss, any or all of which could result in 
losses to us.
Our investments are subject to risks of delinquency, foreclosure and 
loss. In many cases, the ability of a borrower to return our invested 
capital and our expected return is dependent primarily upon the 
successful development, construction and operation of the underlying 
project. If the cash flow of the project is reduced, the borrower’s ability 
to return our capital and our expected return may be impaired. We 
make certain estimates regarding project cash flows or savings during 
the underwriting of our investment. These estimates may not prove 
accurate, as actual results may vary from estimates. The cash flows 
or cost savings of a project can be affected by, among other things: 
the terms of the power purchase or other use agreements used in such 
project; the creditworthiness of the off-taker or project user; price of 
power or services now and in the future; the technology deployed; 
unanticipated expenses in the development or operation of the project 
and changes in national, regional, state or local economic conditions, 
laws and regulations; and force majeure events.
In the event of any default or shortfall of an investment, we will bear 
a risk of loss of principal or equity to the extent of any deficiency 
between the value of the collateral, if any, and the amount of our 
investment, which could have a material adverse effect on our 
cash flow from operations and may impact the cash available for 
distribution to our stockholders. Many of the projects are structured 
as special purpose limited liability companies, which limits our 
ability to realize any recovery to the collateral or value of the 
project itself. In the event of the bankruptcy of a project owner, 
obligor, or other borrower, our investment or the project will be 
deemed to be subject to the avoidance powers of the bankruptcy 
trustee or debtor-in-possession and our or the project’s contractual 
rights may be unenforceable under federal bankruptcy or state law. 
Foreclosure proceedings against a project can be an expensive and 
lengthy process, which could have a substantial negative effect on 
our anticipated return on the foreclosed investment.
The projects in which we invest may incur liabilities 
that rank equally with, or senior to, our investments in 
such projects.
We provide a range of product investment structures, including 
various types of debt and equity securities, senior and 
subordinated loans, real property leases, mezzanine debt, 
preferred equity and common equity. Our projects may have, or 
may be permitted to incur, other liabilities or equity preferences 
that rank equally with, or senior to, our positions or investments 
in such projects or businesses, as the case may be, including with 
respect to grants of collateral. By their terms, such instruments 
may entitle the holders to receive payment of interest, principal 
payments or other distributions on or before the dates on which 
we are entitled to receive payments with respect to the instruments 
in which we invest. Also, in the event of insolvency, liquidation, 
dissolution, reorganization or bankruptcy of an entity in which 
we have invested, holders of instruments ranking senior to our 
investment in that project or business would typically be entitled 
to receive payment in full before we receive any distribution. After 
repaying such senior stakeholders, such project may not have 
any remaining assets to use for repaying its obligation to us. In 
the case of securities ranking equally with instruments we hold, 
we would have to share on an equal basis any distributions with 
other stakeholders holding such instruments in the event of an 
insolvency, liquidation, dissolution, reorganization or bankruptcy 
of the relevant project.
We invest in joint ventures and other similar 
arrangements that subject us to additional risks.
Some of our project companies are structured as joint ventures, 
partnerships, securitizations, and syndications, and we also at times 
invest in project companies through co-investment structures. Part of 
our strategy is to participate with other institutional investors or the 
project’s sponsor on various climate solutions transactions. These 
arrangements are driven by the magnitude of capital required to 
complete acquisitions and the development of climate solutions 
projects and other industry-wide trends that we believe will continue. 
Such arrangements involve risks not present where a third party is not 
involved, including the possibility that partners or co-venturers might 
become bankrupt or otherwise fail to fund their share of required 
capital contributions. Additionally, partners or co-venturers might at 
any time have economic or other business interests or goals different 
from ours. These investments generally provide for a reduced level 
of control over an acquired project because governance rights 
are shared with others. Accordingly, project decisions relating to 
the management, operation and the timing and nature of any exit, 
are often made by a majority vote of the investors or by separate 
agreements that are reached with respect to individual decisions. 
In addition, project operations may be subject to the risk that the 
project owners may make business, financial or management 
choices with which we do not agree or the management of the 
project may take risks or otherwise act in a manner that does not 
serve our interests, including not making distributions. Because we 
19
HASI Form 10-K
Part I
Item 1A. Risk Factors

may not have the ability to exercise control, we may not be able to 
realize some or all of the benefits expected from our investment. If 
any of the foregoing were to occur, our business, financial condition 
and results of operations could suffer as a result.
In addition, some of our joint ventures, partnerships, and equity 
investments subject the sale or transfer of our interests in these project 
companies to rights of first refusal or first offer, tag along or drag 
along rights and buy-sell, call-put or other restrictions. Such rights 
may be triggered at a time when we may not want them to be 
exercised and such rights may inhibit our ability to sell our interest in 
an entity within our desired time frame or on any other desired terms.
Many of the projects in which we invest depend on 
revenues from third-party contractual arrangements, 
including PPAs, that expose the projects to various risks.
Many of the projects in which we invest rely on revenue or 
repayment from contractual commitments of end-customers, 
including federal, state, or local governments for energy 
efficiency projects or utilities or other customers under PPAs. There 
is a risk that these customers may default under their contracts. 
In addition, many of these end-customers are large entities with 
wide ranging activities. An event in a non-related part of the 
business could have a material adverse impact on the financial 
strength of such end-customer, such as the effect of wildfires on 
the California utilities. Furthermore, the bankruptcy, insolvency, or 
other liquidity constraints of one or more customers may result in 
a renegotiation or rejection of the third-party contract, delay the 
receipt of any obligations or reduce the likelihood of collecting 
defaulted obligations. Some projects rely on one customer for their 
revenue and thus the project could be materially and adversely 
affected by any material change in the financial condition of that 
customer. While there may be alternative customers for such a 
project, there can be no assurance that a new contract on the 
same terms will be able to be negotiated for the project.
Certain of our projects with contractually committed revenues 
or other sources of repayment under long term contracts will be 
subject to re-contracting risk in the future. These projects may 
be unable to renegotiate these contracts on equally favorable 
terms or at all once their terms expire. If it is not possible to 
renegotiate these contracts on favorable terms, our business, 
financial condition, results of operations, and prospects could 
be materially and adversely affected.
Revenues at some of the projects in which we invest depend 
on reliable and efficient metering, or other revenue collection 
systems, which are often specified in the contract. If one or 
more of these projects are not able to operate and maintain 
the metering or other revenue collection systems in the manner 
expected, if the operation and maintenance costs, are greater 
than expected, or if the customer disputes the output of the 
revenue collection system, the ability of the project to repay 
our investments or provide a return to us on our asset could be 
materially and adversely affected.
In most instances, projects which sell power under PPAs commit 
to sell minimum levels of generation. If the project generates 
less than the committed volumes, it may be required to buy the 
shortfall of electricity on the open market or make payments of 
liquidated damages or be in default under a PPA, which could 
result in its termination. In the event that any of these events 
were to occur, our business, financial condition, and results of 
operations could suffer as a result.
We are exposed to the credit risk of various project 
sponsors, ESCOs, and others.
We are exposed to credit risks in the commercial projects in which 
we invest. We are also subject to varying degrees of credit risk 
related to ESCOs in government energy efficiency projects in which 
guarantees provided by ESCOs under energy savings performance 
contracts are required in the event that certain energy savings are 
not realized by the customer. 
Where we make loans to or own equity interests in special purposes 
entities such as those that lease solar energy systems to residential 
customers, those special purpose entities often enter into various 
contractual arrangements with, or receive performance guarantees 
from the affiliate project sponsor to ensure satisfactory equipment 
or other project performance over the term of the lease or power 
purchase agreement. To the extent those parties are unable to 
perform on their contractual obligations or performance guarantees 
we may see diminished equity returns or the special purpose entity 
may be unable to repay their loan timely or at all. We seek to mitigate 
these credit risks by employing a comprehensive review and asset 
selection process and careful ongoing monitoring of acquired assets. 
Nevertheless, unanticipated credit losses could occur which could 
adversely impact our operating results. During periods of economic 
downturn in the global economy, the solvency and financial 
wherewithal of counterparties with whom we do business could be 
impacted and our exposure to credit risks from obligors increases, 
and our efforts to monitor and mitigate the associated risks may not 
be effective in reducing our credit risks. In the event a counterparty 
to us or one of our climate solutions projects becomes insolvent or 
unable to make payments, we may fail to recover the full value of 
our investment or realize the value from the counterparty’s contract, 
thus reducing our earnings and liquidity. In addition, the insolvency 
of one or more of our, or one of our climate solutions projects’, 
counterparties could reduce the amount of financing available to 
us, which would make it more difficult for us to leverage the value 
of our assets and obtain substitute financing on attractive terms or 
at all. A material reduction in our financing sources or an adverse 
change in the terms of our financings could have a material adverse 
effect on our financial condition and results of operations. Certain 
participants in the sustainable energy industry have experienced 
significant declines in the value of their equity and difficulty in 
raising or refinancing debt, which increases the credit risk to these 
companies and they may not be able to fulfill their obligations which 
could adversely impact our operating results.

Item 1A. Risk Factors

The ability of our assets to generate revenue from 
certain projects depends on having interconnection 
arrangements and services.
The future success of our assets will depend, in part, on their 
ability to maintain satisfactory interconnection agreements. If the 
interconnection or transmission agreement of a project is terminated for 
any reason, they may not be able to replace it with an interconnection 
and transmission arrangement on terms as favorable as the existing 
arrangement, or at all, or they may experience significant delays or 
costs in connection with securing a replacement. If a network to which 
one or more of the projects is connected experiences equipment or 
operational problems or other forms of “down time,” the affected 
project may lose revenue and be exposed to non-performance 
penalties and claims from its customers. These may include claims 
for damages incurred by customers, such as the additional cost of 
acquiring alternative electricity supply at then-current spot market 
rates. The owners of the network will not usually compensate electricity 
generators for lost income due to down time. In addition, our projects 
may be exposed to a locational basis risk resulting from a difference 
between where the power is generated and the contracted delivery 
point. These factors could materially affect these projects, which 
could negatively affect our business, results of operations, financial 
condition, and cash flow.
Operation of the projects in which we invest involves 
significant risks and hazards that could have a material 
adverse effect on our business, financial condition, 
results of operations and cash flows.
Generally, any projects involving construction are subject to various 
construction and operating delays and risks that have in the past 
caused them to, and may in the future cause them to, incur higher than 
expected costs or generate less than expected amounts of savings or 
outputs, such as electricity in the case of a renewable energy project. 
The ongoing operation of the projects in which we invest involves 
risks that include construction delays, the breakdown or failure of 
equipment or processes or performance below expected levels of 
output or efficiency due to wear and tear, the impact of inflation, latent 
defect, design error or operator error or force majeure events, among 
other things. In addition to natural risks such as earthquake, flood, 
drought, lightning, wildfire, hurricane, ice, wind, and temperature 
extremes, other hazards, such as fire, explosion, structural collapse 
and machinery failure, acts of terrorism or related acts of war, hostile 
cyber intrusions, pandemics or other public health issue, or other 
catastrophic events are inherent risks in the construction and operation 
of a project. These and other hazards can cause significant personal 
injury or loss of life, severe damage to and destruction of property, 
plant and equipment and contamination of, or damage to, the 
environment and suspension of operations. Operation of a project also 
involves risks that the operator will be unable to transport its product 
to its customers in an efficient manner due to a lack of transmission 
capacity. Unplanned outages of projects, including extensions of 
scheduled outages due to mechanical failures or other problems, 
occur from time to time and are an inherent risk of the business. 
Unplanned outages typically increase operation and maintenance 
expenses and may reduce revenues as a result of selling less electricity 
or require the project to incur significant costs as a result of obtaining 
replacement power from third parties in the open market to satisfy 
forward power sales obligations. Any extended interruption in a 
project’s construction or operation, a project’s inability to operate its 
assets efficiently, manage capital expenditures and costs or generate 
earnings and cash flow could have a material adverse effect on the 
repayment of and return on our investment and our business, financial 
condition, results of operations and cash flows. While the projects 
maintain insurance, obtain warranties from vendors and obligate 
contractors to meet certain performance levels, the proceeds of such 
insurance, warranties or performance guarantees may not cover the 
lost revenues, increased expenses or liquidated damages payments 
should the project experience any equipment breakdowns, insurance 
claims or non-performance by contractors or vendors.
Some of the projects in which we invest may require 
substantial operating or capital expenditures in 
the future.
Many of the projects in which we invest are capital intensive and 
require substantial ongoing expenditures for, among other things, 
additions and improvements, and maintenance and repair of plant 
and equipment related to project operations. In addition, there 
may be cash needs to settle certain contractual obligations of the 
projects, such as settlements or margining requirements related to 
hedging activities. While we do not typically bear the responsibility 
for these expenditures, any failure by the equity owner to make 
necessary operating or capital expenditures could adversely impact 
project performance. In addition, some of these expenditures may 
not be recoverable from current or future contractual arrangements.
The use of real property rights that we acquire or 
are used for our climate solutions projects may be 
adversely affected by the rights of lienholders and 
leaseholders that are superior to those of the grantors 
of those real property rights to us. 
The projects in which we invest often require large areas of land 
for construction and operation or other easements or access to the 
underlying land. In addition, we may acquire rights to land or other 
real property. Although we believe that we, or the projects in which we 
invest, have valid rights to all material easements, licenses and rights of 
way, not all of such easements, licenses and rights of way are registered 
against the lands to which they relate and may not bind subsequent 
owners. Some of our real property rights and projects generally are, 
and are likely to continue to be, located on land occupied pursuant 
to long-term easements and leases. The ownership interests in the land 
subject to these easements and leases may be subject to mortgages 
securing loans or other liens (such as tax liens) and other easement 
and lease rights of third parties (such as leases of water, oil or mineral 
rights) that were created prior to, or are superior to, our or our projects’ 
21
HASI Form 10-K
Part I
Item 1A. Risk Factors

easements and leases. As a result, our rights may be subject, and 
subordinate, to the rights of those third parties. We typically obtain 
representations or perform title searches or obtain title insurance to 
protect our real property interest and our investments in our projects 
against these risks. Such measures may, however, be inadequate to 
protect against all risk of loss of rights to use the land rights we have 
acquired or the land on which these projects are located, which could 
have a material and adverse effect on our land rights, our projects and 
their financial condition and operating results.
We have invested in, through various structures, land 
or leasehold interests that are used by renewable 
energy projects. Negative market conditions or adverse 
events affecting tenants, or the industries in which 
they operate, could have an adverse impact on our 
underwritten returns. Moreover, many of our real estate 
assets are concentrated in similar geographic locations, 
which subjects us to an increased risk of significant 
loss if any property declines in value, incurs a natural 
disaster or if we are unable to lease a property.
We have indirectly, through equity method investments and 
securitization trust structures, invested in land leased to renewable 
energy projects in specific regions. Our returns and cash flow 
from such investments are dependent on favorable leasing terms 
and tenant stability, and are vulnerable to factors such as lease 
performance, market value fluctuations, natural disasters, and 
tenants’ financial health. Tenants experiencing project downturns, 
increased costs, or insolvencies could lead to significant losses. If 
tenants terminate or do not renew leases, we may not be able to 
re-lease the land with favorable leases or sell the land at prices that 
allow us to recover our investment or achieve our desired investment 
returns. Tenant bankruptcy could limit claims against unpaid rent, 
leading to operational losses. Concentration of projects in certain 
states exposes us to potential adverse political or regulatory 
changes or to potential natural disasters, impacting property values 
and leasing capabilities.
Performance of projects where we invest may be 
harmed by future labor disruptions and economically 
unfavorable collective bargaining agreements.
A number of the projects where we invest could have workforces that 
are unionized or in the future may become unionized and, as a result, 
are required to negotiate the wages, benefits and other terms with 
many of their employees collectively. If these projects were unable 
to negotiate acceptable contracts with any of their unions as existing 
agreements expire, they could experience a significant disruption 
of their operations, higher ongoing labor costs and restrictions on 
their ability to maximize the efficiency of their operations, which 
could have a material and adverse effect on our business, financial 
condition and results of operations. In addition, in some jurisdictions 
where our projects have operations, labor forces have a legal right to 
strike, which may have a negative impact on our business, financial 
condition and results of operations, either directly or indirectly, for 
example if a critical upstream or downstream counterparty was itself 
subject to a labor disruption that impacted the ability of our projects 
to operate.
We invest in projects that rely on third parties to 
manufacture quality products or provide reliable 
services in a timely manner and the failure of these 
third parties could cause project performance to be 
adversely affected.
We invest in projects that typically rely on third parties to select, 
manage or provide equipment or services. Third parties may be 
responsible for choosing vendors, including equipment suppliers 
and subcontractors. Project success often depends on third 
parties who are capable of installing and managing projects and 
structuring contracts that provide appropriate protection against 
construction and operational risks. In many cases, in addition to 
contractual protections and remedies, project owners may seek 
guaranties, warranties and construction bonding to provide 
additional protection.
The warranties provided by the third parties and, in some cases, 
their subcontractors, typically limit any direct harm that results from 
relying on their products and services. However, there can be no 
assurance that a supplier or subcontractor will be willing or able 
to fulfill its contractual obligations and make necessary repairs or 
replace equipment. In addition, these warranties generally expire 
within one to five years or may be of limited scope or provide 
limited remedies. If projects are unable to avail themselves of 
warranty protection or receive the expected protection under 
the terms of the guaranties or bonding, we may need to incur 
additional costs, including replacement and installation costs, 
which could adversely impact our investment.
In addition, renewable energy projects rely on electric and other 
types of transmission lines and facilities owned and operated by 
third parties to receive and distribute their energy. Any substantial 
access barriers to these lines and facilities could adversely impact 
the demand or financial performance for such projects and 
our investments. 
Liability relating to environmental matters may impact 
the value of properties that we may acquire or the 
properties underlying our assets.
Under various U.S. federal, state and local laws, an owner or 
operator of real estate or a project may become liable for the costs 
of removal of certain hazardous substances released from the 
project or any underlying real property. These laws often impose 
liability without regard to whether the owner or operator knew of, 
or was responsible for, the release of such hazardous substances.
The presence of hazardous substances may adversely affect our, or 
another owner’s, ability to sell a contaminated project or borrow 
using the project as collateral. To the extent that we, or another project 
22

Item 1A. Risk Factors

owner, become liable for removal costs, our investment, or the ability 
of the owner to make payments to us, may be negatively impacted.
We acquire real property rights, make investments in projects that 
own real property, have collateral consisting of real property and 
in the course of our business, we may take title to a project or its 
underlying real estate assets relating to one of our debt financings. 
In these cases, we could be subject to environmental liabilities with 
respect to these assets. To the extent that we become liable for 
the removal costs, our results of operation and financial condition 
may be adversely affected. The presence of hazardous substances, 
if any, may adversely affect our ability to sell the affected real 
property or the project and we may incur substantial remediation 
costs, thus harming our financial condition.
Insurance and contractual protections may not always 
cover lost revenue, increased expenses or liquidated 
damages payments.
Although the assets or projects in which we invest generally have 
insurance, supplier warranties, subcontractors performance 
assurances such as bonding and other risk mitigation measures, the 
proceeds of such insurance, warranties, bonding or other measures 
may not be adequate to cover lost revenue, increased expenses or 
liquidated damages payments that may be required in the future.
The repayment of certain of our assets is dependent 
upon collection of payments from residential customers 
and we may be indirectly subject to consumer 
protection laws and regulations. 
Certain obligors to which we have credit exposure are, or may be, 
subject to consumer protection laws, such as federal truth-in-lending, 
consumer leasing, and equal credit opportunity laws and 
regulations, as well as state and local sales and finance laws 
and regulations. Claims arising out of actual or alleged violations 
of law may be asserted against those obligors by individuals or 
governmental entities and may expose them to significant damages 
or other penalties, including fines, or could reduce the likelihood 
the residential customer may pay their obligation, which could limit 
their ability to repay borrowings or make equity distributions to us.
Risks Related to Our Company and Structure 
Our business could be harmed if key personnel 
terminate their employment with us.
Our success depends, to a significant extent, on the continued 
services of our senior management team. We have entered into 
employment agreements with certain members of our senior 
management team. Notwithstanding these agreements, there can 
be no assurance that any or all members of our senior management 
team will remain employed by us. We do not maintain key person 
life insurance on any of our officers. The loss of services of one or 
more members of our senior management team could harm our 
business and our prospects.
Conflicts of interest could arise as a result of 
our structure.
Conflicts of interest could arise in the future as a result of the 
relationships between us and our affiliates, on the one hand, and 
our Operating Partnership or any partner thereof, on the other. Our 
directors and officers have duties to our company under applicable 
Delaware law in connection with our management. Our duties, 
as the general partner, to our Operating Partnership and our 
partners may come into conflict with the duties of our directors and 
officers to us.
Under Delaware law, a general partner of a Delaware limited 
partnership owes its limited partners the duties of good faith and 
fair dealing. Other duties, including fiduciary duties, may be 
modified or eliminated in the partnership’s partnership agreement, 
except that conflict of interest transactions may still run afoul of 
implied contractual standards under Delaware law. The partnership 
agreement of our Operating Partnership provides that, for so long 
as we own a controlling interest in our Operating Partnership, any 
conflict that cannot be resolved in a manner not adverse to either 
our stockholders or the limited partners will be resolved in favor 
of our stockholders. We have not obtained an opinion of counsel 
covering the provisions set forth in the partnership agreement of our 
Operating Partnership that purport to waive or restrict our fiduciary 
duties that would be in effect under common law were it not for the 
partnership agreement of our Operating Partnership.
Additionally, the partnership agreement of our Operating Partnership 
expressly limits our liability by providing that neither we, as the general 
partner of the Operating Partnership, nor any of our directors or 
officers, will be liable or accountable in damages to our Operating 
Partnership, its limited partners or their assignees for errors in judgment, 
mistakes of fact or law or for any act or omission if the general partner, 
director or officer, acted in good faith. In addition, our Operating 
Partnership is required to indemnify us, our affiliates and each of 
our and their respective officers, directors, employees and agents 
to the fullest extent permitted by applicable law against any and all 
losses, claims, damages, liabilities (whether joint or several), expenses 
(including, without limitation, attorneys’ fees and other legal fees and 
expenses), judgments, fines, settlements and other amounts arising 
from any and all claims, demands, actions, suits or proceedings, civil, 
criminal, administrative or investigative, that relate to the operations of 
the Operating Partnership, provided that our Operating Partnership 
will not indemnify any such person for (1) willful misconduct or a 
knowing violation of the law, (2) any transaction for which such 
person received an improper personal benefit in violation or breach 
of any provision of the partnership agreement of our Operating 
Partnership, or (3) in the case of a criminal proceeding, the person 
had reasonable cause to believe the act or omission was unlawful.

Our charter and bylaws, as well as Delaware law, 
contain provisions that could discourage acquisition 
bids or merger proposals, which may adversely affect 
the market price our common stock.
Our charter and bylaws contain provisions that could delay or 
prevent a change in control of our company. These provisions 
could also make it difficult for stockholders to elect directors that 
are not nominated by the current members of our Board or take other 
corporate actions, including effecting changes in our management. 
These provisions include: 
• the denial of any right of our stockholders to remove members of 
our Board except upon the approval of at least two-thirds of the 
shares of then entitled to vote at an election of directors;
• the exclusive right of our Board to elect a director to fill a vacancy 
created by the expansion of our Board or the resignation, death, 
or removal of a director, which prevents stockholders from being 
able to fill vacancies on our Board;
• limitations on the ability of our stockholders to call special meetings;
• a prohibition on actions by holders of our common stock by written 
consent, which forces stockholder action to be taken at an annual 
or special meeting of our stockholders;
• establishing advance notice provisions for stockholder proposals 
and nominations for elections to our Board to be acted upon at 
meetings of stockholders;
• the ability of our Board to issue shares of preferred stock and to 
determine the price and other terms of those shares, including 
preferences and voting rights, without stockholder approval, which 
could be used to significantly dilute the ownership of a hostile 
acquirer; and
• the requirement that the affirmative vote of the holders of at least 
two-thirds in voting power of all the then-outstanding shares of 
our common stock be obtained to amend our charter or bylaws.
Our charter designates the Court of Chancery of the 
State of Delaware as the sole and exclusive forum for 
certain types of actions and proceedings that may 
be initiated by our stockholders, which could limit our 
stockholders’ ability to obtain a favorable judicial 
forum for disputes with us or our directors, officers, 
employees or agents.
Our charter provides that, to the fullest extent permitted by law, 
and unless we consent in writing to the selection of an alternative 
forum, the Court of Chancery of the State of Delaware (or, in the 
event that the Chancery Court does not have jurisdiction, the federal 
district court of the State of Delaware) will be the sole and exclusive 
forum for (i) any derivative action or proceeding brought on behalf 
of us, (ii) any action asserting a claim of breach of a fiduciary duty 
owed by any current or former director, officer, other employee 
or stockholder of ours to us or our stockholders, (iii) any action 
asserting a claim arising pursuant to any provision of the General 
Corporation Law of the State of Delaware (the “DGCL”), our charter 
or our bylaws (as either may be amended or restated) or as to 
which the DGCL confers jurisdiction on the Court of Chancery of 
the State of Delaware or (iv) any action asserting a claim governed 
by the internal affairs doctrine of the law of the State of Delaware. 
However, our charter provides that federal district courts of the 
United States of America will be the sole and exclusive forum for 
claims under the Securities Act.
These provisions may have the effect of discouraging lawsuits against 
us or our directors, officers, employees or agents. Any person or 
entity purchasing or otherwise acquiring any interest in shares of our 
capital stock will be deemed to have notice of and consented to the 
forum provisions in our charter. However, the enforceability of similar 
forum provisions in other companies’ charters has been challenged 
in legal proceedings, and it is possible that a court could find these 
types of provisions to be unenforceable. If a court were to find these 
provisions of our charter inapplicable to, or unenforceable in respect 
of, one or more of the specified types of actions or proceedings, we 
may incur additional costs associated with resolving such matters in 
other jurisdictions, which could adversely affect our business, financial 
condition or results of operations.
Failure to qualify as a REIT for prior taxable years 
would subject us to U.S. federal income tax and 
potentially state and local tax. 
We elected to be taxed as a REIT commencing with our taxable year 
ended December 31, 2013, but recently terminated our election, 
effective January 1, 2024. Prior to terminating our REIT election, our 
qualification as a REIT depended upon our satisfaction of certain 
asset, income, organizational, distribution, stockholder ownership 
and other requirements on a continuing basis. We structured our 
activities in a manner designed to satisfy all the requirements to 
qualify as a REIT. However, the REIT qualification requirements are 
extremely complex and interpretation of the U.S. federal income 
tax laws governing qualification as a REIT is limited. Furthermore, 
any opinion of our counsel, regarding qualification as a REIT is not 
binding on the Internal Revenue Service (the “IRS”). Satisfying the 
asset tests depended on our analysis of the characterization and 
fair market values of our assets, some of which are not susceptible 
to a precise determination. Furthermore, during the period that 
we elected to be taxed as a REIT, we invested in certain assets 
that we believed were qualifying assets for purposes of the REIT 
assets tests, such as mezzanine loans meeting certain requirements 
and commercial property assessed clean energy assets, and no 
assurance can be provided that the IRS would agree with such 
characterizations. Accordingly, if certain of our operations were 
to be recharacterized by the IRS, such recharacterization could 
jeopardize our ability to have satisfied all requirements for 
qualification as a REIT for prior taxable years. Furthermore, future 
legislative, judicial or administrative changes to the U.S. federal 
income tax laws could be applied retroactively, which could result 
in our disqualification as a REIT for prior taxable years.

HASI Form 10-K

Item 1A. Risk Factors

We received a private letter ruling from the Internal Revenue Service 
(“IRS”), which we refer to as the Ruling, relating to our ability to treat 
certain of our assets as qualifying REIT assets. We were entitled to 
rely on this Ruling for those assets which fit within the scope of the 
Ruling only to the extent that we had the legal and contractual rights 
described in the Ruling, and we operated in accordance with the 
relevant facts described in the Ruling request we submitted, such facts 
were accurately presented and only to the extent that the Ruling was 
not inconsistent with the Real Property Regulations (as discussed in 
more detail below). As a result, no assurance can be given that we 
were able to rely on the Ruling during the period that we elected to 
be taxed as a REIT.
In August of 2016, the Treasury Department and the IRS published 
regulations which we refer to as the Real Property Regulations relating 
to the definition of “real property” for purposes of the REIT income and 
asset tests with respect to our taxable years that we elected to be taxed 
as a REIT beginning after December 31, 2016. Among other things, 
the Real Property Regulations provide that an obligation secured by 
a structural component of a building or other inherently permanent 
structure qualifies as a real estate asset for REIT qualification purposes 
only if such obligation is also secured by a real property interest in the 
inherently permanent structure served by such structural component. 
This aspect of the Real Property Regulations has important implications 
for our qualification as a REIT during the periods that we elected 
to so qualify, because a significant portion of our REIT qualifying 
assets consisted of receivables that were secured by liens on installed 
structural improvements designed to improve the energy efficiency of 
buildings and a significant portion of our REIT qualifying gross income 
was interest income earned with respect to such receivables.
The structural improvements securing the receivables held by us 
during the period we elected to be taxed as a REIT generally 
qualified as “fixtures” under local real property law, as well as 
under the Uniform Commercial Code, or the UCC, which governs 
rights and obligations of parties in secured transactions. Although 
not controlling for REIT purposes, the general rule in the United 
States is that once improvements are permanently installed in real 
properties, such improvements become fixtures and thus take on 
the character of and are considered to be real property for certain 
state and local law purposes. In general, in the United States, laws 
governing fixtures, including the UCC and real property law, afford 
lenders who have secured their financings with security interests 
in fixtures with rights that extend not just to the fixtures that secure 
their financings, but also to the real properties in which such fixtures 
have been installed. By way of example only, Section 9-604(b) 
of the UCC, which has been adopted in all but two states in the 
United States, permits a lender secured by fixtures, upon a default, 
to enforce its rights under the UCC or under applicable real property 
laws. Although there is limited authority directly on point, given the 
nature of, and the extent to which, the structural improvements 
securing the receivables held by us during the period we elected 
to be taxed as a REIT were integrated into and served the related 
buildings, we believe that the better view is that the nature and 
scope of our rights in such buildings that inured to us as a result 
of our receivables were sufficient to satisfy the requirements of 
the Real Property Regulations described above. In addition to the 
limited authority directly on point, two other important caveats apply 
in this regard. First, the Real Property Regulations do not define 
what is required for an obligation secured by a lien on a structural 
component to also be secured by a real property interest in the 
building served by such structural component. However, the initial 
proposed version of the Real Property Regulations, which never 
became effective, included a requirement that the interest in the real 
property held by a REIT be “equivalent” to the interest in a structural 
component held by the REIT in order for the structural component to 
be treated as a real estate asset. This requirement was ultimately not 
included in the final Real Property Regulations, in part in response 
to comments that such requirement may negatively affect investment 
in energy efficiency and renewable energy assets. We believe the 
deletion of this requirement implies that under the final Real Property 
Regulations, our rights in the building during the period we elected 
to be taxed as a REIT did not need to be equivalent to our rights 
in the structural components serving the building. Second, real 
property law is typically relegated to the states and the specific 
rights available to any lien or mortgage holder, including our 
rights as a fixture lien holder described above, may vary between 
jurisdictions as a result of a range of factors, including the specific 
local real property law requirements and judicial and regulatory 
interpretations of such laws, and the competing rights of mortgage 
and other lenders. During the period we elected to be taxed as a 
REIT, we applied the analysis described above in a number of states 
that have adopted Section 9-604(b) of the UCC. In addition, in 
states where Section 9-604(b) of the UCC has not been adopted, 
we applied the analysis described above based on the application 
of the local real property laws of that state to the extent that we 
received advice from counsel in those jurisdictions that local real 
property law provided us with appropriate rights to the buildings 
in which the structural improvements securing our receivables were 
installed. Furthermore, we applied the analysis described above 
to certain receivables secured by liens on structural improvements 
installed in buildings located in certain U.S. installations outside of 
the United States, based on our view that such installations were 
subject to U.S. sovereignty and as a result the UCC applied in such 
installations. While a number of cases have addressed the rights of 
fixture lien holders generally, there are limited judicial interpretations 
in only a few jurisdictions that directly address the rights and remedies 
available to a fixture lien holder in the real property in which the 
fixtures have been installed. Such rights have been addressed in 
some cases that support our position and, in factual circumstances 
distinguishable from our own, in some cases where the courts have 
found these rights to be more limited. The resolution of these issues 
in many jurisdictions therefore has remained uncertain. As a result 
of the foregoing, no assurance can be given that the IRS will not 
challenge our position that the receivables that we held during the 
periods that we elected to be taxed as a REIT met the requirements 
of the Real Property Regulations or that, if challenged, such position 
would be sustained.
25

Item 1A. Risk Factors

The preamble to the Real Property Regulations provides that, to 
the extent a private letter ruling issued prior to the issuance of the 
Real Property Regulations is inconsistent with the Real Property 
Regulations, the private letter ruling is revoked prospectively from 
the applicability date of the Real Property Regulations. We do 
not believe that the Ruling is inconsistent with the Real Property 
Regulations because we believe the analysis in the Ruling was 
based on similar principles as the relevant portions of the Real 
Property Regulations, and accordingly we do not believe that 
the Real Property Regulations impacted our ability to rely on 
the Ruling. However, no assurance can be given that the IRS 
would not successfully assert that we were not permitted to rely 
on the Ruling during periods that we elected to be taxed as a 
REIT because the Ruling had been revoked by the Real Property 
Regulations.
If the IRS were to assert that a significant portion of the receivables 
that we held during periods that we elected to be taxed as a REIT 
did not qualify as real estate assets and did not generate income 
treated as interest income from mortgages on real property, we 
would fail to satisfy both the gross income requirements and asset 
requirements applicable to REITs during the relevant periods. 
During the period that we elected to be taxed as a REIT, no more 
than 20% of the value of our total assets were permitted to consist 
of stock and securities of one or more taxable REIT subsidiaries, or 
TRSs. In order to satisfy the TRS limitation, we made loans to our 
TRSs that met the requirements to be treated as qualifying investments 
of new capital, which are generally treated as real estate assets 
under the Internal Revenue Code of 1986, as amended, or “the 
Code”. Because such loans were treated as real estate assets for 
purposes of the REIT requirements, we did not treat these loans as 
TRS securities for purposes of the TRS asset limitation. However, 
no assurance can be provided that the IRS may not successfully 
assert that such loans should be treated as securities of our TRSs, 
which could adversely impact our qualification as a REIT during the 
periods that we elected to be taxed as a REIT. In addition, our TRSs 
had obtained financing in transactions in which we and our other 
subsidiaries had provided guaranties and similar credit support. 
Although we believe that these financings were properly treated 
as financings of our TRSs for U.S. federal income tax purposes, 
no assurance can be provided that the IRS would not assert that 
such financings should be treated as issued by other entities in our 
structure, which could impact our compliance with the TRS limitation 
and the other REIT requirements during the period that we elected 
to be taxed as a REIT.
If the IRS were to determine that we failed to qualify as a REIT for 
any prior taxable year ended on or before December 31, 2023, 
and we do not qualify for certain statutory relief provisions, we 
would be subject to U.S. federal income tax on our taxable income 
for such taxable year at the applicable corporate rate. If that were 
to happen, we would also be disqualified from treatment as a 
REIT for the four taxable years following the year in which we lost 
our REIT qualification. Losing our REIT qualification for any prior 
taxable year(s) could reduce our current and/or future net earnings 
available for investment or distribution to stockholders because 
of additional tax liability for any such year(s). If we were to lose 
our REIT qualification for any prior taxable year(s), we might be 
required to borrow funds or liquidate some investments in order to 
pay any applicable tax.
Our ability to utilize our NOLs and other 
carryforwards may be limited.
Under the Code, a corporation is generally allowed a deduction 
for net operating losses (“NOLs”) carried over from prior taxable 
years, subject to certain limitations. Our NOL carryforwards are 
subject to adjustment on audit by the Internal Revenue Service and 
the respective state taxing authorities. Additionally, certain of the 
NOL carryforwards may expire before we can generate sufficient 
taxable income to use them.
Our ability to use our NOLs and other carryforwards depends on 
the amount of taxable income generated in future periods. There 
can be no assurance that an additional valuation allowance 
on our net deferred tax assets will not be required should our 
financial performance be negatively impacted in the future. Such 
valuation allowance could be material. In addition, the use of 
NOLs and other carryforwards to offset taxable income is subject 
to various limitations, which could limit our ability to utilize these 
tax attributes to reduce our taxes even if we generate sufficient 
taxable income.
A corporation’s ability to deduct its federal NOL carryforwards 
and to utilize certain other available tax attributes can be 
substantially constrained under the general annual limitation 
rules of Section 382 of the Code (“Section 382”) if it undergoes 
an “ownership change” as defined in Section 382 (generally 
where cumulative stock ownership changes among material 
stockholders exceed 50% during a rolling three-year period). 
An ownership change may severely limit or effectively eliminate 
our ability to utilize our NOL carryforwards and other tax 
attributes. In October 2023, our Board adopted a tax benefits 
preservation plan (the “Tax Benefits Preservation Plan”) in order 
to preserve our ability to use our NOLs and certain other tax 
attributes to reduce potential future income tax obligations. The 
Tax Benefits Preservation Plan was terminated in conjunction with 
our conversion from a Maryland corporation to a Delaware 
corporation in July 2024 (the “Conversion”). In the Conversion, 
we adopted our charter. Our charter includes provisions that are 
also intended to reduce the risk of an “ownership change” under 
Section 382 of the Code (the “Charter Tax Benefit Provisions”). 
The Charter Tax Benefit Provisions generally restrict any person 
or entity from attempting to transfer any of our stock to the 
extent that transfer would, if effected and subject to certain 
exceptions, (i) result in an individual, entity, firm, corporation, 
estate, trust or other person or group of persons described in 
the Charter Tax Benefit Provisions as a “Person” owning 4.8% 
or more of our common stock (which the Charter Tax Benefit 
26
HASI Form 10-K
Part I
Item 1A. Risk Factors

Provisions refer to as a “Prohibited Ownership Percentage”) or 
(ii) increase the ownership percentage of any Person that has a 
Prohibited Ownership Percentage, subject to certain exceptions. 
The Charter Tax Benefit Provisions provide that any transfer that 
violates the Charter Tax Benefit Provisions shall be null and void 
ab initio and shall not be effective to transfer any record, legal, 
beneficial or any other ownership of the number of shares which 
result in the violation of the Charter Tax Benefit Provisions.
Some persons who are beneficial owners (as defined under the 
Exchange Act) of 4.8% or more of our Common Stock are not 
“4.8-percent stockholders” (defined by reference to the definition 
of “5-percent shareholder” under Section 382) and hence would 
not affect our ownership shift for purposes of Section 382. We 
expect our Board to generally grant waivers, if requested, to allow 
purchases by such persons, though there is also no guarantee our 
Board will grant any such waivers.
There is no assurance, however, that the deterrent mechanism will 
be effective, and such acquisitions may still occur. In addition, the 
Charter Tax Benefit Provision may adversely affect the marketability 
of our common stock by discouraging existing or potential investors 
from acquiring our common stock or additional shares of our 
common stock.
We may be subject to adverse legislative or regulatory 
tax changes that could increase our tax liability, 
reduce our operating flexibility, and reduce the market 
price of shares of our stock.
Changes to the tax laws may occur, and any such changes could 
have an adverse effect on an investment in shares of our stock 
or on the market value or the resale potential of our assets. Our 
stockholders are urged to consult with an independent tax advisor 
with respect to the status of legislative, regulatory or administrative 
developments and proposals and their potential effect on an 
investment in shares of our stock.
Our management and employees depend on 
information systems and system failures could 
significantly disrupt our business, which may, in 
turn, negatively affect the market price of our 
common stock and our ability to pay dividends to 
our stockholders.
Our underwriting process and our asset and financial management 
and reporting are dependent on our present and future 
communications and information systems. Any failure or interruption 
of these systems could cause delays or other problems in our 
originating, financing, investing, asset and financial management 
and reporting activities, which could have a material adverse effect 
on our operating results.
We contract with information technology service 
providers where, in part, we rely upon their systems 
and controls for the quality of the data provided. The 
inappropriate establishment and maintenance of 
these systems and controls could cause information 
that we use to operate our business to be unavailable 
or inaccurate and could negatively impact our 
financial results.
Our information technology architecture is partially outsourced. 
These systems and processes may be either internet based or 
through traditional outsourced functions and certain of these 
arrangements are new or emerging. When we contract with these 
service providers, we attempt to evaluate the quality of their systems 
and controls before we execute the arrangement and may rely 
on third party reviews and audits of these service providers and 
attempt to implement certain processes to ensure the quality of the 
data received from these service providers. Because of the nature 
and maturity of the technology such efforts may be unsuccessful or 
incomplete and the unavailability of these systems or the inaccurate 
data provided from these service providers could negatively impact 
our financial results.
Cybersecurity risks and cyber incidents may adversely 
affect our business by causing a disruption to our 
operations, a compromise or corruption of our 
confidential information, a misappropriation of funds, 
and/or damage to our business relationships, all of 
which could negatively impact our financial results.
A cyber incident is considered to be any adverse event that 
threatens the confidentiality, integrity or availability of our 
information resources. These incidents may be an intentional attack 
or an unintentional event and could involve gaining unauthorized 
access to our information systems for purposes of misappropriating 
assets, stealing confidential information, corrupting data or causing 
operational disruption. The risk of a security breach or disruption, 
particularly through cyber-attacks or cyber intrusions, including by 
computer hackers, nation-state affiliated actors, and cyber terrorists, 
has generally increased as the number, intensity and sophistication 
of attempted attacks and intrusions from around the world have 
increased, and will likely continue to increase in the future. The result 
of these incidents could include disrupted operations, misstated or 
unreliable financial data, disrupted market price of our common 
stock, misappropriation of assets, liability for stolen assets or 
information, increased cybersecurity protection and insurance cost, 
regulatory enforcement, litigation and damage to our relationships. 
These risks require continuous and likely increasing attention and 
other resources from us to, among other actions, identify and quantify 
these risks, upgrade and expand our technologies, systems and 
processes to adequately address them and provide periodic training 
27
HASI Form 10-K
Part I
Item 1A. Risk Factors

for our employees to assist them in detecting phishing, malware 
and other schemes. Such attention diverts time and other resources 
from other activities and there is no assurance that our efforts will 
be effective. Additionally, the cost of maintaining such systems and 
processes, procedures and internal controls may increase from its 
current level. Potential sources for disruption, damage or failure 
of our information technology systems include, without limitation, 
computer viruses, security breaches, human error, cyber- attacks, 
natural disasters and defects in design. Additionally, due to the size 
and nature of our company, we rely on third-party service providers 
for many aspects of our business. The networks and systems that our 
third-party vendors have established or use may not be effective. As 
our reliance on technology has increased, so have the risks posed 
to both our information systems and those provided by third-party 
service providers. Our processes, procedures and internal controls 
that are designed to mitigate cybersecurity risks and cyber intrusions 
do not guarantee that a cyber incident will not occur or that our 
financial results, operations or confidential information will not be 
negatively impacted by such an incident. 
Even if we are not targeted directly, cyberattacks on the U.S. and 
foreign governments, financial markets, financial institutions, or 
other businesses, including borrowers, vendors, software creators, 
cybersecurity service providers, and other third parties with whom 
we do business, may occur, and such events could disrupt our 
normal business operations and networks in the future.
Major public health issues and related disruptions in 
the U.S. and global economy and financial markets 
could adversely impact or disrupt our financial 
condition and results of operations.
In recent years, the outbreaks of a number of diseases, including 
COVID-19, avian influenza, H1N1, and other viruses have resulted 
in and increased the risk of a pandemic or major public health issues. 
We believe that our ability to operate, our level of business activity 
and the profitability of our business, as well as the values of, and the 
cash flows from, the assets we own could in the future be impacted 
by another pandemic or other major public health issue. While we 
have implemented risk management and contingency plans and taken 
preventive measures and other precautions, no predictions of specific 
scenarios can be made with certainty and such measures may not 
adequately predict the impact on our business from such events.
We may seek to expand our business internationally, 
which would expose us to additional risks that we do 
not face in the United States. A failure to manage these 
additional risks could have an adverse effect on our 
business, financial condition and operating results.
We generate substantially all of our revenue from operations in 
the United States. We have begun to expand and may seek to 
expand our investments outside of the United States in the future. 
These operations will be subject to a variety of risks that we do not 
face in the United States, including risk from changes in foreign 
country regulations, infrastructure, legal systems and markets. Other 
risks include possible difficulty in repatriating overseas earnings and 
fluctuations in foreign currencies.
Our overall success in international markets will depend, in part, on 
our ability to succeed in different legal, regulatory, economic, social 
and political conditions. We may not be successful in developing and 
implementing policies and strategies that will be effective in managing 
these risks in each country where we decide to do business. Our failure 
to manage these risks successfully could harm our international projects, 
reduce our international income or increase our costs, thus adversely 
affecting our business, financial condition and operating results.
Risks Relating to Regulation
We cannot predict the unintended consequences and 
market distortions that may stem from far-ranging 
governmental intervention in the economic and 
financial system or from regulatory reform of the 
oversight of financial markets.
The U.S. federal government, the Federal Reserve Board of 
Governors, the U.S. Treasury, the SEC, U.S. Congress and other 
governmental and regulatory bodies have taken, are taking or may 
in the future take, various actions to address inflation, financial crises, 
perceived trade imbalances, or other areas of regulatory concern. 
Such actions could have a dramatic impact on our business, results 
of operations and financial condition, and the cost of complying with 
any additional laws and regulations or the elimination or reduction in 
scope of various existing laws and regulations could have a material 
adverse effect on our financial condition and results of operations. 
The far-ranging government intervention in the economic and 
financial system may carry unintended consequences and cause 
market distortions. We are unable to predict at this time the extent 
and nature of such unintended consequences and market distortions, 
if any. The inability to evaluate the potential impacts could have a 
material adverse effect on the operations of our business.
Loss of our 1940 Act exemptions may adversely affect 
us, the market price of shares of our common stock 
and our ability to distribute dividends.
We conduct our operations so that we are not required to register as 
an investment company under the 1940 Act. Section 3(a)(1)(A) of 
the 1940 Act defines an investment company as any issuer that is or 
holds itself out as being engaged primarily in the business of investing, 
reinvesting or trading in securities. Section 3(a)(1)(C) of the 1940 
Act defines an investment company as any issuer that is engaged or 
proposes to engage in the business of investing, reinvesting, owning, 
holding or trading in securities and owns or proposes to acquire 
investment securities having a value exceeding 40% of the value 
28
HASI Form 10-K
Part I
Item 1A. Risk Factors

of the issuer’s total assets (exclusive of U.S. Government securities 
and cash items) on a non-consolidated basis, which we refer to as 
the 40% test. Excluded from the term “investment securities,” among 
other things, are U.S. Government securities and securities issued 
by majority-owned subsidiaries that are not themselves investment 
companies and are not relying on the exemption from the definition 
of investment company set forth in Section 3(c)(1) or Section 3(c)(7) 
of the 1940 Act.
We conduct our businesses primarily through our subsidiaries and 
our operations so that we comply with the 40% test. The securities 
issued by any wholly-owned or majority-owned subsidiaries that we 
hold or may form in the future that are exempted from the definition 
of “investment company” based on Section 3(c)(1) or 3(c)(7) of 
the 1940 Act, together with any other investment securities we may 
own, may not have a value in excess of 40% of the value of our total 
assets on a non-consolidated basis. Certain of our subsidiaries rely 
on or will rely on an exemption from registration as an investment 
company under the 1940 Act pursuant to Section 3(c)(5)(C) of the 
1940 Act, which is available for entities which are not primarily 
engaged in issuing redeemable securities, face-amount certificates 
of the installment type or periodic payment plan certificates and 
which are primarily engaged in the business of purchasing or 
otherwise acquiring mortgages and other liens on and interests in 
real estate. This exemption generally requires that at least 55% of 
such subsidiaries’ portfolios must be comprised of qualifying assets 
and at least 80% of each of their portfolios must be comprised of 
qualifying assets and real estate-related assets under the 1940 Act. 
Consistent with guidance published by the SEC staff, we intend to 
treat as qualifying assets for this purpose loans secured by projects 
for which the original principal amount of the loan did not exceed 
100% of the value of the underlying real property portion of the 
collateral when the loan was made. We intend to treat as real estate-
related assets non-controlling equity interests in joint ventures that 
own projects whose assets are primarily real property. In general, 
with regard to our subsidiaries relying on Section 3(c)(5)(C), we 
rely on other guidance published by the SEC or its staff or on our 
analyses of guidance published with respect to other types of assets 
to determine which assets are qualifying real estate assets and real 
estate-related assets.
In addition, one or more of our subsidiaries qualifies for an 
exemption from registration as an investment company under the 
1940 Act pursuant to either Section 3(c)(5)(A) of the 1940 Act, 
which is available for entities which are not engaged in the business 
of issuing redeemable securities, face-amount certificates of the 
installment type or periodic payment plan certificates, and which 
are primarily engaged in the business of purchasing or otherwise 
acquiring notes, drafts, acceptances, open accounts receivable, 
and other obligations representing part or all of the sales price 
of merchandise, insurance, and services, or Section 3(c)(5)(B) of 
the 1940 Act, which is available for entities primarily engaged in 
the business of making loans to manufacturers, wholesalers, and 
retailers of, and to prospective purchasers of, specified merchandise, 
insurance, and services. These exemptions generally require that at 
least 55% of such subsidiaries’ portfolios must be comprised of 
qualifying assets that meet the requirements of the exemption. We 
intend to treat energy efficiency loans where the loan proceeds are 
specifically provided to finance equipment, services and structural 
improvements to properties and other facilities and renewable 
energy and other climate solutions projects or improvements as 
qualifying assets for purposes of these exemptions. In general, we 
also expect, with regard to our subsidiaries relying on Section 3(c)
(5)(A) or (B), to rely on guidance published by the SEC or its staff, 
including reliance on a no-action letter obtained in connection 
with Sections 3(c)(5)(A) and 3(c)(5)(B) of the 1940 Act, or on 
our analyses of guidance published with respect to other types 
of assets to determine which assets are qualifying assets under 
the exemptions.
Although we monitor the portfolios of our subsidiaries relying on 
the Section 3(c)(5)(A), (B) or (C) exemptions periodically and 
prior to each acquisition, there can be no assurance that such 
subsidiaries will be able to maintain their exemptions. Qualification 
for exemptions from registration under the 1940 Act will limit our 
ability to make certain investments. For example, these restrictions 
will limit the ability of these subsidiaries to make loans that are not 
secured by real property or that do not represent part or all of the 
sales price of merchandise, insurance, and services.
There can be no assurance that the laws and regulations governing 
the 1940 Act, including the Division of Investment Management of 
the SEC providing more specific or different guidance regarding 
these exemptions, will not change in a manner that adversely affects 
our operations. For example, on August 31, 2011, the SEC issued a 
concept release (No. IC-29778; File No. SW7-34-11, Companies 
Engaged in the Business of Acquiring Mortgages and Mortgage-
Related Instruments) pursuant to which it is reviewing the scope of 
the exemption from registration under Section 3(c)(5)(C) of the 1940 
Act. While the SEC has yet to provide additional information on its 
position relating to these exemptions and timing of any future changes 
to the exemptions remain unknown, any additional guidance from 
the SEC or its staff from this process or in other circumstances could 
provide additional flexibility to us, or it could further inhibit our ability 
to pursue the strategies we have chosen. If we or our subsidiaries 
fail to maintain an exemption from the 1940 Act, we could, among 
other things, be required either to (1) change the manner in which 
we conduct our operations to avoid being required to register as an 
investment company, (2) effect sales of our assets in a manner that, or 
at a time when, we would not otherwise choose to do so or (3) register 
as an investment company, any of which could negatively affect our 
business, our ability to make distributions, our financing strategy and 
the market price for shares of our common stock.
We have not requested the SEC or its staff to approve our treatment 
of any company as a majority-owned subsidiary and neither the 
SEC nor its staff has done so. If the SEC or its staff were to disagree 
with our treatment of one or more companies as majority-owned 
subsidiaries, we would need to adjust our strategy and our assets in 
order to continue to pass the 40% test. Any such adjustment in our 
strategy could have a material adverse effect on us.
29
HASI Form 10-K
Part I
Item 1A. Risk Factors

Rapid changes in the values of our assets may make it 
more difficult for us to maintain our exemption from the 
1940 Act.
If the market value or income potential of our assets changes as 
a result of changes in interest rates, general market conditions, 
government actions or other factors, we may need to adjust the 
portfolio mix of our real estate assets and income or liquidate our 
non-qualifying assets to maintain our exemption from the 1940 Act. 
If changes in asset values or income occur quickly, this may be 
especially difficult to accomplish. This difficulty may be exacerbated 
by the illiquid nature of the assets we may own. We may have to 
make decisions that we otherwise would not make absent 1940 
Act considerations.
Risks Related to our Borrowings and Hedging
We use financial leverage in executing our business 
strategy, which may adversely affect the returns on our 
assets and may reduce cash available for distribution 
to our stockholders, as well as increase losses when 
economic conditions are unfavorable.
We use debt to finance our assets, including credit facilities, recourse 
and non-recourse debt, securitizations, and syndications. Changes 
in the financial markets and the economy generally could adversely 
affect one or more of our lenders or potential lenders and could 
cause one or more of our lenders, potential lenders or institutional 
investors to be unwilling or unable to provide us with financing 
or participate in securitizations or could increase the costs of that 
financing or securitization. Some of our borrowings will have a 
remaining balance when they come due. If we are unable to repay 
or refinance the remaining balance of this debt, or if the terms of 
any available refinancing are not favorable, we may be forced to 
liquidate assets or incur higher costs which may significantly harm 
our business, financial condition, results of operations, and our 
ability to make distributions, which could in turn cause the value 
of our common stock to decline. The return on our assets and cash 
available for distribution to our stockholders may be reduced to the 
extent that market conditions prevent us from leveraging our assets 
or increase the cost of our financing relative to the income that can 
be derived from the assets acquired. Increases in our financing costs 
will reduce cash available for distributions to stockholders. We may 
not be able to meet our financing obligations and, to the extent that 
we cannot, we risk the loss of some or all of our assets to liquidation 
or sale to satisfy the obligations.
An increase in our borrowing costs relative to the 
interest we receive on our assets may adversely affect 
our profitability and our cash available for distribution 
to our stockholders. Our borrowings may have a 
shorter duration than our assets.
As some of our borrowings will have a remaining balance at 
maturity, we may be required to enter into new borrowings at 
higher rates or to sell certain of our assets to repay the loan. Our 
credit facilities have rates that adjust on a frequent basis based 
on prevailing short-term interest rates. Increases in interest rates, 
or a flattening or inversion of the yield curve, reduce the spread 
between the returns on our assets which are typically priced using 
longer-term interest rates and the cost of any new borrowings or 
borrowings where the interest rate adjusts to market rates or is based 
on shorter-term rates. This change in interest rates may adversely 
affect our earnings and, in turn, cash available for distribution to 
our stockholders. In addition, as we may use short-term borrowings 
that are generally short-term commitments of capital, lenders may 
respond to market conditions making it more difficult for us to obtain 
continued financing. If we are not able to renew our then existing 
facilities or arrange for new financing on terms acceptable to us, 
or if we default on our covenants or are otherwise unable to access 
funds under any of these facilities, we may have to curtail entering 
into new transactions and/or dispose of assets. We will face these 
risks given that a number of our borrowings have a shorter duration 
than the assets they finance.
While we have an established Board-approved 
leverage limit, our Board may change our leverage 
limits without stockholder approval.
We are not restricted by any regulatory requirements to maintain 
our leverage ratio at or below any particular level. The amount of 
leverage we may deploy for particular assets will depend upon 
the availability of particular types of financing and our assessment 
of the credit, liquidity, price volatility and other risks of those 
assets and the credit quality of our financing counterparties. We 
have established leverage limits which are discussed in Item 7, 
Management’s Discussion and Analysis of Financial Conditions 
and Results of Operations—Liquidity and Capital Resources. 
However, our charter and bylaws do not limit the amount or type 
of indebtedness we can incur, and our Board has changed, and 
has the discretion to deviate from or change at any time in the 
future, our leverage policy, which could result in our business 
having a different risk profile. We utilize non-recourse facilities 
on certain types of assets that have significantly higher leverage. 
On these facilities, the lenders’ primary recourse is to the pledged 
assets. If the value of the pledged assets is below the value of the 
debt or if we default on a facility, the lender would be able to 
foreclose on all the pledged assets, which would result in losses 
and reduce our assets and the cash available for distributions to 
stockholders. We may apply too much leverage to our assets or 
may employ an inefficient financing strategy to our assets.
30
HASI Form 10-K
Part I
Item 1A. Risk Factors

The use of securitizations and special purpose entities 
exposes us to additional risks.
We typically retain the residual value associated with a securitization. 
We have also established special purpose entities through which 
we hold only a partial or subordinate interest or a residual value 
after taking into account our non-recourse debt facilities or a right to 
participate in the profits of such entity once it achieves a predefined 
threshold. As a holder of the residual value or other such interests, 
we are more exposed to losses on the underlying collateral because 
the interest we retain in the securitization vehicle or other entity 
would be subordinate to the more senior notes or interests issued to 
investors and we would, therefore, absorb all of the losses, up to the 
value of our interests, sustained with respect to the underlying assets 
before the owners of the notes or other interests experience any 
losses. In addition, the inability to securitize our Portfolio or assets 
within our Portfolio could hurt our performance and our ability to 
grow our business.
We also use various special purpose entities to own and finance 
our assets. These subsidiaries incur various types of debt, that can 
be used to finance one or more of our assets. This debt is typically 
structured as non-recourse debt, which means it is repayable 
solely from the revenue from the investment financed by the debt 
and is secured by the related physical assets, major contracts, 
cash accounts and in some cases, a pledge of our ownership 
interests in the subsidiaries involved in the projects. Although this 
subsidiary debt is typically non-recourse to us, we make certain 
representations and warranties or enter into certain guaranties of 
our subsidiary’s obligations or covenants to the non-recourse debt 
holder, the breach of which may require us to make payments to 
the lender. We may also from time to time determine to provide 
financial support to the subsidiary in order to maintain rights to the 
project or otherwise avoid the adverse consequences of a default. 
In the event a subsidiary defaults on its indebtedness, its creditors 
may foreclose on the collateral securing the indebtedness, which 
may result in us losing our ownership interest in some or all of 
the subsidiary’s assets. The loss of our ownership interest in a 
subsidiary or some or all of a subsidiary’s assets could have a 
material adverse effect on our business, financial condition and 
operating results.
Certain of our existing credit facilities and debt contain, 
and any future financing facilities may contain, 
covenants that restrict our operations and may inhibit 
our ability to grow our business and increase revenues.
Certain of our existing credit facilities and debt contain, and 
any future financing facilities may contain, various affirmative 
and negative covenants, including maintenance of an interest 
coverage ratio and limitations on the incurrence of liens and 
indebtedness, investments, fundamental organizational changes, 
dispositions, changes in the nature of business, transactions with 
affiliates, use of proceeds and stock repurchases. In addition, the 
terms of our non-recourse debt include restrictions and covenants, 
including limitations on our ability to transfer or incur liens on the 
assets that secure the debt. For further information see Item 7. 
Management’s Discussion and Analysis of Financial Condition 
and Results of Operations—Liquidity and Capital Resources.
The covenants and restrictions included in our existing financings 
do, and the covenants and restrictions to be included in any future 
financings may, restrict our ability to, among other things:
• incur or guarantee additional debt;
• make certain investments, originations or acquisitions;
• make distributions on or repurchase or redeem capital stock;
• engage in mergers or consolidations;
• reduce liquidity below certain levels;
• grant liens;
• have a tangible net worth below a defined threshold;
• incur operating losses for more than a specified period; and
• enter into transactions with affiliates.
Our non-recourse debt limits our ability to take action with regard 
to the assets pledged as security for the debt. These restrictions, 
as well as any other covenants contained in any future financings, 
may interfere with our ability to obtain financing, or to engage 
in other business activities, which may significantly limit or 
harm our business, financial condition, liquidity and results of 
operations. Certain financing agreements also contain cross-
default provisions, so that if a default occurs under any one 
agreement, the lenders under our other agreements could also 
declare a default. A default and resulting repayment acceleration 
could significantly reduce our liquidity, which could require us to 
sell our assets to repay amounts due and outstanding. This could 
also significantly harm our business, financial condition, results 
of operations, and our ability to make distributions, which could 
cause the value of our common stock to decline. A default will 
also significantly limit our financing alternatives such that we will 
be unable to pursue our leverage strategy, which could curtail 
the returns on our assets.
In addition, certain of our financing arrangements contain provisions 
that provide for a preference in cash flow allocations to the lender 
from our assets or an acceleration of principal payments owed when 
certain conditions are present related to the underlying assets that 
serve as collateral for the financing. These provisions may limit our 
ability to obtain distributions from the underlying assets and could 
impact our cash flow and expected returns.
We have issued senior unsecured notes that require us to maintain 
a certain amount of unencumbered assets as a part of our Portfolio. 
These provisions may limit our ability to leverage certain assets and 
limit our overall debt levels.

HASI Form 10-K
Part I
Item 1A. Risk Factors

We, or the projects in which we invest, enter into 
hedging transactions that could expose us to contingent 
liabilities or additional credit risk in the future and 
adversely impact our financial condition.
Part of our strategy, or the strategy of the projects in which we 
invest, involves entering into hedging transactions that could 
require us to fund cash payments in certain circumstances (e.g., 
the early termination of the hedging instrument caused by an event 
of default or other early termination event, or the decision by a 
counterparty to request margin it is contractually owed under the 
terms of the hedging instrument). The amount due would be equal 
to the unrealized loss of the open swap positions with the respective 
counterparty and could also include other fees and charges. These 
economic losses will be reflected in our, or the project’s, financial 
statements, and our, or the project’s, ability to fund these obligations 
will depend on the liquidity of our, or the project’s, assets and access 
to capital at the time, and the need to fund these obligations could 
adversely impact our financial condition.
Even though most swaps are cleared through a central counterparty 
clearinghouse, certain transactions could be executed bilaterally with 
a counterparty. While we have the ability to require counterparties 
to post, to the extent we have not obtained sufficient collateral, we 
would remain exposed to our counterparty’s ability to perform on its 
obligations under each hedge and cannot look to the creditworthiness 
of a central counterparty for performance. As a result, if a hedging 
counterparty cannot perform under the terms of the hedge, we 
would not receive payments due under that hedge, we may lose 
any unrealized gain associated with the hedge and the hedged 
liability would cease to be hedged. While we would seek to terminate 
the relevant hedge transaction and may have a claim against the 
defaulting counterparty for any losses, including unrealized gains, 
there is no assurance that we would be able to recover such amounts 
or to replace the relevant hedge on economically viable terms or 
at all. In such case, we could be forced to cover our unhedged 
liabilities at the then current market price. We may also be at risk for 
any collateral we have pledged to secure our obligations under the 
hedge if the counterparty becomes insolvent or files for bankruptcy.
Furthermore, our interest rate swaps and other hedge transactions 
are subject to increasing statutory and other regulatory requirements 
and, depending on the identity of the counterparty, applicable 
international requirements. Recently, new regulations have been 
promulgated by U.S. and foreign regulators to strengthen the 
oversight of swaps, and any further actions taken by such regulators 
could constrain our strategy or increase our costs, either of which 
could materially and adversely impact our results of operations.
Moreover, the projects in which we invest, may enter into various 
forms of hedging including interest rate and power price hedging. 
To the extent they enter into such hedges, the financial results of the 
project will be exposed to similar risks as described above which 
could adversely impact our results of operations. Further, the hedges 
entered into by us or the projects in which we invest may not be 
effective which could adversely impact our economics. 
If we, or our projects, choose not to pursue, or fail to 
qualify for, hedge accounting treatment, our operating 
results under GAAP may be impacted because 
losses on the derivatives that we enter into may not 
be offset by a change in the fair value of the related 
hedged transaction.
We, or our projects, may choose not to pursue, or fail to qualify 
for, hedge accounting treatment relating to derivative and hedging 
transactions. We, or our projects, may fail to qualify for hedge 
accounting treatment for a number of reasons, including if we, or our 
projects, use instruments that do not meet the Accounting Standards 
Codification (“ASC”) Topic 815 definition of a derivative, we, or 
our projects, fail to satisfy ASC Topic 815 hedge documentation 
and hedge effectiveness assessment requirements or the hedge 
relationship is not highly effective. If we, or our projects, fail to 
qualify for, or choose not to pursue, hedge accounting treatment, 
our, or our projects, operating results may be impacted because 
losses on the derivatives that we, or our projects, enter into may 
not be offset by a change in the fair value of the related hedged 
transaction in our statement of operations presented under GAAP.
Risks Related to Our Common Stock
An active trading market for our common stock may 
not continue, which could cause our common stock to 
trade at a discount and make it difficult for holders of 
our common stock to sell their shares.
Our common stock is listed on the New York Stock Exchange 
(“NYSE”). However, an active trading market for our common stock 
may not continue, which could cause our common stock to trade 
at a discount to historical prices. Some of the factors that have or in 
the future could negatively affect the market price of our common 
stock include:
• our actual or projected operating results, financial condition, cash 
flows and liquidity or changes in business strategy or prospects;
• changes in the mix of our investment products and services, 
including the level of securitizations or fee income in any quarter;
• actual or perceived conflicts of interest with individuals, including 
our executives;
• our ability to arrange financing for projects;
• equity issuances by us, or share resales by our stockholders, or 
the perception that such issuances or resales may occur;
• seasonality in construction and demand for our investments;
• actual or anticipated accounting problems;
• publication of research reports about us or the climate solutions 
industry;
• changes in market valuations of similar companies;
32
HASI Form 10-K
Part I
Item 1A. Risk Factors

• adverse market reaction to any increased indebtedness we may 
incur in the future;
• commodity price changes;
• interest rate changes;
• additions to or departures of our key personnel;
• speculation or negative publicity in the press or investment 
community;
• our failure to meet, or the lowering of, our earnings estimates or 
those of any securities analysts;
• increases in market interest rates, which may lead investors to 
demand a higher distribution yield for our common stock, and 
would result in increased interest expenses on certain of our debt;
• changes in governmental policies, regulations or laws;
• failure to maintain our exemption from registration as an investment 
company under the 1940 Act;
• price and volume fluctuations in the stock market generally; and
• general market and economic conditions, including the current 
state of the credit and capital markets.
Market factors unrelated to our performance also have, and could 
in the future, negatively impact the market price of our common 
stock. One of the factors that investors may consider in deciding 
whether to buy or sell our common stock is our distribution rate as 
a percentage of our stock price relative to market interest rates. If 
market interest rates increase, prospective investors may demand 
a higher distribution rate or seek alternative investments paying 
higher dividends or interest. As a result, interest rate fluctuations 
and conditions in capital markets have, or in the future could, 
affect the market value of our common stock.
Common stock and preferred stock eligible for future 
sale may have adverse effects on our share price.
Subject to applicable law, our Board, without stockholder approval, 
may authorize us to issue additional authorized and unissued shares 
of common stock and preferred stock on the terms and for the 
consideration it deems appropriate.
We cannot predict the effect, if any, of future sales of our common 
stock or the availability of shares for future sales, on the market price 
of our common stock. Sales of substantial amounts of common stock 
or the perception that such sales could occur may adversely affect 
the prevailing market price for our common stock.
We cannot guarantee the timing, amount, or payment 
of dividends on our common stock.
As a REIT, we were generally required, among other things, 
to distribute annually at least 90% of our REIT taxable income 
(without regard to the deduction for dividends paid and excluding 
net capital gains) each year for us to have qualified as, and to 
have maintained our qualification as a REIT. Effective January 1, 
2024, we revoked our REIT election and starting in 2024 we were 
taxed as a C corporation, and as a result, in 2024 and going 
forward, we were no longer subject to this requirement. However, 
our current policy is to pay quarterly distributions, though the timing, 
declaration, amount and payment of any dividends will be within 
the discretion of our Board, and will depend upon various factors, 
including our earnings, our financial condition, our liquidity, our 
debt covenants, applicable provisions of Delaware law and other 
factors as our Board may deem relevant from time to time. Moreover, 
no assurance can be given that we will be able to make distributions 
to our stockholders at any time in the future or that the level of any 
distributions we do make to our stockholders will achieve a market 
yield or increase or even be maintained over time, any of which 
could materially and adversely affect us.
Future offerings of debt or equity securities, which may 
rank senior to our common stock, may adversely affect 
the market price of our common stock.
Our present debt ranks, and any future debt would rank, senior 
to our common stock. Such debt is, and likely will be, governed 
by a loan agreement, an indenture, or other instrument containing 
covenants restricting our operating flexibility. Additionally, our 
convertible securities, and any equity securities or convertible 
or exchangeable securities that we issue in the future may have 
rights, preferences and privileges more favorable than those of our 
common stock and may result in dilution to owners of our common 
stock. We and, indirectly, our stockholders will bear the cost of 
issuing and servicing such debt or securities. Because our decision 
to issue debt or equity securities in any future offering will depend 
on market conditions and other factors beyond our control, we 
cannot predict or estimate the amount, timing, or nature of our future 
offerings. Thus, holders of our common stock will bear the risk of our 
future offerings reducing the market price of our common stock and 
diluting the value of their stock holdings in us.

Risk management and strategy
We have implemented and maintain various information security 
processes at each of our remote and office locations designed 
to identify, assess and manage material risks from cybersecurity 
threats to our critical computer networks, third-party hosted services, 
communications systems, hardware and software, and our critical 
data, including intellectual property and confidential information 
that is proprietary, strategic or competitive in nature (“Information 
Systems and Data”).
Our Chief Technology Officer (“CTO”), who also serves as our chief 
information security officer, helps identify, assess and manage our 
cybersecurity threats and risks. Collaborating with their team, they are 
responsible for steering the company-wide cybersecurity strategy, 
policy, standards, architecture, and processes. They also identify and 
assess risks from cybersecurity threats by monitoring and evaluating 
our threat environment and our risk profile using various methods.
The Company’s information security program, led by our CTO, 
collaborates with various departments within the organization, 
such as information technology, legal, enterprise risk management, 
human resources, accounting, finance, and internal audit, as 
well as external third-party partners. This collaboration aims to 
identify, mitigate, and plan for potential cybersecurity threats 
comprehensively. Additionally, the Company consistently evaluates 
and enhances its processes, procedures, and management 
approaches in response to evolving cybersecurity landscapes. 
Depending on the environment, we implement and maintain various 
technical, physical, and organizational measures, processes, 
standards and policies designed to manage and mitigate material 
risks from cybersecurity threats to our Information Systems and 
Data. These include incident management, change management, 
network segmentation, cyber protection and containment, detection

the National Institute of Standards and Technology Cyber Security 
Framework and regularly test our controls and incident response plans.
Our assessment and management of material risks from cybersecurity 
threats are integrated into our overall risk management processes. 
For example, (1) cybersecurity risk is addressed as a component 
of our enterprise risk management program; (2) the information 
security function works with our leadership team to prioritize our risk 
management processes and mitigate cybersecurity threats that are 
more likely to lead to a material impact to our business; (3) our CTO 
evaluates material risks from cybersecurity threats against our overall 
business objectives and reports to the Finance & Risk Committee of 
our Board (the “Finance and Risk Committee”), which evaluates our 
overall enterprise risk. 
We use third-party service providers to assist us from time to time 
to identify, assess, and manage material risks from cybersecurity 
threats, as well as to perform a variety of other functions throughout 
our business. We have enlisted the services of a third-party managed 
detection and response firm to conduct continuous monitoring of 
our information systems, including intrusion detection and alerting. 
We also regularly engage with assessors, consultants, auditors, 
and other third parties to review our cybersecurity program to help 
identify areas for continued focus, improvement, and compliance.
For a description of the risks from cybersecurity threats that may 
materially affect us and how they may do so, see our risk factors 
under “Part 1. Item 1A. Risk Factors” in this Annual Report on 
Form 10-K, including “Cybersecurity risks and cyber incidents 
may adversely affect our business by causing a disruption to 
our operations, a compromise or corruption of our confidential 
information, a misappropriation of funds, and/or damage to our 
business relationships, all of which could negatively impact our 
financial results.”
Governance
Our Board addresses our cybersecurity risk management as part 
of its general oversight function. The Finance & Risk Committee 
is responsible for overseeing the Company’s cybersecurity risk 
management processes, including oversight and mitigation of 
risks from cybersecurity threats. Our cybersecurity risk assessment 
and management processes are implemented and maintained by 
certain Company management, including our CTO. The CTO has 
a over two decades of information technology and cybersecurity 
leadership experience.

The following discussion should be read in conjunction with our financial statements and accompanying notes included in Item 8. Financial 
Statements and Supplementary Data, of this Form 10-K. Refer to ‘Item 7 — Management’s Discussion and Analysis of Financial Condition 
and Results of Operations’ on our Form 10-K for the year ended December 31, 2023 for a discussion of our results for the year ended

Overview
We are an investor in sustainable infrastructure assets advancing the 
energy transition. With more than $13 billion in managed assets, 
our investment strategy is focused primarily on long-lived real assets 
that are supported by long-term recurring cash flows. In addition 
to net investment income from our portfolio, we also generate 
gains-on-sale from securitization transactions, as well as on-going 
fees from asset management and other services.
We are internally managed by an executive team that has 
extensive relevant industry knowledge and experience, and a 
team of over 150 clean energy investment, operating, and technical 
professionals. We have long-standing relationships with the leading 
clean energy project developers, owners and operators, utilities, 
and ESCOS, which provide recurring, programmatic investment 
and fee-generating opportunities, while also enabling scale benefits 
and operational efficiencies.
We completed approximately $2.3 billion of transactions during both 
2024 and 2023. As of December 31, 2024, our managed assets 
total approximately $13.7 billion, and generally fall into one of three 
categories: (1) our Portfolio, which represents investments we have 
retained on our balance sheet, (2) assets in our co-investment structures 
that are not in our Portfolio but held by our investment partners in 
these structures, and (3) assets we have securitized by transferring 
all or a portion of the economics of the investment, typically using 
securitization trusts, to institutional investors in exchange for cash and/
or residual interests in the assets and in some cases, ongoing fees. As 
of December 31, 2024, we held approximately $6.6 billion of assets 
in our Portfolio, and we also managed approximately $7.1 billion in 
securitization trusts or co-investment vehicles that are not consolidated 
on our balance sheet.
See Item 1. Business for a further discussion of our business, investing 
strategy, and financing strategy.
Market Conditions
The market for sustainable infrastructure assets in which our 
investments are predominantly focused continues to grow, powered 
by a number of long-term trends impacting the U.S. economy and 
energy markets. These include, but are not limited to (1) expectations 
for faster growth in U.S. electricity demand, (2) heightened 
concerns about inflation and, in turn, greater prioritization of 
lower cost electricity sources like solar power and wind power, 
(3) broader recognition of the links between climate change and 
human activities, combined with greater awareness of, and concern 
about, the increase in frequency and magnitude of environmental 
disasters that have led to damages and losses costing hundreds of 
billions of dollars per year, and (4) greater attention to the need for 
grid resilience and reliability, as well as national energy security. 
Altogether, this is expected to lead to significant increase in U.S. 
load growth which would require an increase in electric generation 
capacity through the rest of this decade and beyond. 
First and foremost, there have been significant changes in the 
outlook for U.S. power demand, with load growth now expected 
to experience its most significant increase since before the turn of 
this century. For the last 25 years, U.S. electricity demand has been 
essentially flat at approximately 4,000 TWh per year, according to 
the U.S. Energy Information Administration (the “EIA”), due largely 
to the impact of successful energy efficiency and conservation 
initiatives. More recently, however, a number of new macro trends 
have materially altered the U.S. electricity market, including growth 
in data centers, a resurgence in domestic manufacturing, as well as 
the broader trend of electrification of more sectors of the economy, 
including on-road transportation, industrial manufacturing, and 
space heating, among others. 
• Data centers. Spurred in part by unprecedented investment in 
artificial intelligence, data center power demand is expected 
to grow substantially, from less than 4% of total U.S. power 
demand in 2024 to more than 11% by 2030, or approximately 
400 TWh, according to McKinsey, which estimates such 
demands would necessitate approximately 55 GW of new 
generation capacity and require approximately $500 billion of 
38
HASI Form 10-K
Part II
Item 6. [Reserved]

capital investment in data center energy infrastructure, excluding 
transmission and distribution investment as well as the investments 
in computer equipment within data centers. Data centers represent 
approximately 30-40% of the total increase in U.S. electricity 
demand of more than 1,000 TWh that McKinsey estimates 
between 2024 and 2030. 
• Domestic manufacturing. Following a decades-long trend towards 
offshoring, there has been a sharp reversal in recent years in 
favor of reshoring, as manufacturers have sought to (a) reduce 
supply chain vulnerabilities exposed by the Covid-19 pandemic, 
(b) address a growing consumer segment in favor of “Made in 
the USA” products, and (c) overcoming growing national security 
concerns stemming from the country’s higher dependence on 
foreign countries for manufacturing goods, particularly for 
strategic industries like industrial materials, energy products, and 
semiconductors. Furthered by supportive government policies, 
culminating in transformative legislation and incentives including 
the Infrastructure Investment and Jobs Act, the Inflation Reduction 
Act, and the CHIPS Act, there has been a resurgence of investment 
in domestic manufacturing in the United States over the last few 
years. According to the U.S. Census Bureau, in 2024, U.S. 
spending on construction of manufacturing facilities surpassed 
$230 billion, up from approximately $75 billion in 2020. This 
rise in spending on domestic manufacturing is expected to create 
a minimum of 250 million square feet of new manufacturing 
space and 210,000 manufacturing jobs by 2030, according to 
NewMark. This growth in domestic manufacturing is estimated to 
drive an increase in U.S. electricity demand of more than 100 TWh 
by 2030, according to Rystad Energy. 
• The “electrification of everything.” Further driving U.S. load growth 
higher is the broader trend of electrification expanding to more 
products and processes that had previously been powered by fossil 
fuels like diesel, oil, and natural gas. One of the most prominent 
of these trends is the electrification of on-road transportation. 
With sales of new light-duty electric vehicles in the United States 
growing 7% to more than 1.3 million in 2024, representing more 
than 8% of total new car sales, there were more than 4.8 million 
light-duty battery electric vehicles registered in the United States 
at the end of 2023, based on U.S. Department of Energy data, 
up from less than 100,000 in 2012. With electric vehicles on 
U.S. roads expected to grow to more than 78 million by 2035, 
representing 26% of all passenger vehicles on the road, according 
to Edison Energy Institute’s October 2024 forecast, it is estimated 
that electric vehicle charging alone could increase annual U.S. 
electricity demand by more than 300 TWh by 2035. In addition, 
electrification has taken hold across a number of other sectors 
of the U.S. economy, including space heating–underscored by 
annual sales of heat pumps surpassing sales of gas furnaces 
since 2022–as well as the electrification of industrial processes, 
including greater adoption of electric furnaces and electric boilers, 
among other processes and products, which we believe will drive 
U.S. electricity demand even higher.
The second important trend affecting our market and demand for 
assets we invest in is heightened concern and focus on inflation, and 
in turn, the desire to supply the expected U.S. load growth over the 
next decade with the lowest cost and least inflationary sources of 
electricity. From 2021 to 2023, the United States economy, along 
with many other economies across the globe, suffered from the 
first inflation shock in multiple decades. This has led to heightened 
sensitivity to prices among consumers and businesses, which we 
believe will lead to extensive effort by businesses and policymakers 
to minimize inflation in energy prices. We believe this will lead not 
only to an “all of the above” energy strategy that does not limit any 
potential sources of energy, but emphasizes a widespread supply 
of energy from as many sources as possible, with a prioritization of 
the lowest cost sources of energy. According to the levelized cost of 
energy (“LCOE”) reports that Lazard Inc. publishes annually, solar 
energy and wind energy now provide the lowest potential cost of 
electricity in the United States, even on an unsubsidized basis, which 
we believe will continue to lead to high demand for clean energy 
infrastructure assets to help minimize energy inflation.
The third trend is the recognition of the real and growing financial 
cost of climate change. According to the Pew Research Center, 54% 
of U.S. adults in 2022 described climate change as a major threat to 
the country’s well-being, up from 44% in 2010, while approximately 
two-thirds of US. adults in 2023 said renewable energy development 
should be prioritized over expanding oil, gas, and coal production. 
Further, we believe the substantial increase over the last several 
years in both the magnitude and frequency of environmental 
disasters linked to climate change will lead to greater appreciation 
not only of the broader impacts of climate change but also the very 
real financial costs it is incurring as well. According to the National 
Oceanic and Atmospheric Administration (“NOAA”), the year 2024 
was the warmest year on record, while the ten warmest years since 
1850 have occurred in the last decade. In 2024, there were 27 
confirmed climate disaster events in the United States with losses 
exceeding $1 billion that in aggregate accounted for total damage 
of approximately $183 billion, according to National Centers for 
Environmental Information, including Hurricane Helene at a cost of 
approximately $79 billion and Hurricane Milton at approximately 
$34 billion. This compares to 28 climate disaster events in the United 
States with losses exceeding $1 billion in 2023 representing an 
aggregate cost of approximately $95 billion, and 2010 with 7 such 
climate disaster events with aggregate losses exceeding $20 billion. 
More recently, the wildfires in Los Angeles County in January 2025 
have resulted in damage that are expected exceed $250 billion, 
according to AccuWeather, which would make it the costliest natural 
disaster in U.S. history, surpassing Hurricane Katrina in 2005. It 
has become clear that climate change is not merely a concern for 
environmentalists but a real and growing threat to communities 
across the United States (and globe) that is resulting in substantial 
and growing financial cost to society. We believe the persistence 
and possibility of intensification of these events will not only result 
in even greater recognition of the threat of climate change but a 
growing appreciation for clean energy and other climate solutions 
and in turn an increase in the types of sustainable infrastructure 
investment opportunities that are the focus of HASI’s business model.
39
HASI Form 10-K
Part II
Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Finally, this expected growth in U.S. electricity demand combined 
with the increase in climate events and disasters, as discussed above, 
is also leading to greater attention to and prioritization of improving 
the resilience and reliability of the grid, while greater geopolitical 
conflict and uncertainty along with volatility in fossil fuel prices is 
leading to growing prioritization of national energy security. We 
believe renewable energy and storage provide important solutions 
to both of these issues. Distributed energy resources, particularly 
rooftop solar, and battery storage improve grid resilience, 
while lowering dependence and utilization of transmission and 
distribution infrastructure. In addition, renewable energy’s use of 
freely available natural resources, such as solar and wind energy, 
reduce the electric grid’s reliance on fossil fuels, which despite higher 
domestic production, continues to be primarily imported from foreign 
nations, many of whom are hostile to the United State. As a result, 
we believe the growing focus on grid reliability and resilience, as 
well as national energy independence and security, are supportive 
of growth in clean energy demand in general, and in sustainable 
infrastructure assets.
Altogether, these factors are transforming the U.S. power markets 
and providing powerful tailwinds to demand for the sustainable 
infrastructure assets that HASI invests in and the returns we generate 
on them. 
Separately, interest rates can also impact how we operate and 
manage our business. Interest rates were volatile in 2024, and are 
expected to continue to be volatile into 2025. The Federal Reserve 
Board of Governors increased the federal funds rate (the rate at 
which banks lend to one another) 11 times in 2022 and 2023 for 
an overall increase of 5.25% to reduce inflation to stated targets. 
In 2024, as inflationary pressures eased, the Board of Governors 
lowered rates three times for an overall decrease of 1.00%. See 
“Item 7A. Quantitative and Qualitative Disclosures about Market 
Risk-Interest Rate and Borrowing Risks” for an analysis of the impact 
of rates on our business. To date, inflationary pressures have not 
had a material impact on our business.
Finally, with most of our investments and assets serving the energy 
markets, energy–and in particular–electricity prices also can impact 
the pricing and rates of returns of our investments. According to the 
EIA, the average annual Henry Hub natural gas price for 2024 was 
$2.21/MMBtu, a decrease of 16% from 2023 and 68% from 2022, 
the largest two year decline on record. The EIA cites robust natural 
gas production and limited growth in natural gas consumption as 
key contributors to the sharp decrease in price compared to prior 
years. The EIA’s outlook for 2025 and 2026 is for the average price 
of natural gas to increase, to an average of $3.10 per MMBtu in 
2025, and $4.00 per MMBtu in 2026. While we typically invest in 
projects which sell power at prices which have been prenegotiated 
under power purchase agreements, lower natural gas prices, may 
negatively impact, renewable energy projects that sell wholesale 
power on a “merchant” basis at spot market prices, as wholesale 
electricity prices are closely tied to wholesale natural gas prices in 
many parts of the United States. For more detail on commodity price 
impacts, see “Item 7A. Quantitative and Qualitative Disclosures 
about Market Risk-Commodity Price Risk”. 
Notwithstanding any concerns that current market conditions have 
raised for our business, we believe significant opportunities exist 
for us to grow our business. As a long-term participant committed 
to providing capital for climate solutions, we plan to continue to 
fund projects that meet our underwriting standards and look for 
opportunities to expand our business.
Factors Impacting our Operating Results 
We expect that our results of operations will be affected by a number 
of factors and will primarily depend on the size and mix of our 
Portfolio, the income we receive from securitizations, syndications 
and other services, our Portfolio’s credit risk profile, changes in 
market interest rates, commodity prices, federal, state and/or 
municipal governmental policies, general market conditions in local, 
regional and national economies, and maintain our exemption from 
registration as an investment company under the 1940 Act and the 
impact of climate change.
Portfolio Size and Mix
The size and mix of our Portfolio will be a key driver of revenue. 
Generally, as the size of our Portfolio on our balance sheet grows 
the amount of our revenue will increase. Our Portfolio may grow 
at an uneven pace as opportunities to originate new assets may 
be irregularly timed, and the timing and extent of our success in 
such originations cannot be predicted. To the extent the size of our 
Portfolio changes due to equity method investment activity, the 
income or loss from such investments will not be included in revenue 
but are reflected as income (loss) from equity method investments 
in our income statement and will vary over time. In addition, we 
may decide for any particular asset that we should securitize or 
otherwise sell a portion, or all, of the asset, which would result 
in gain on sale of receivables and investments or fee income as 
described below. The level of portfolio activity will fluctuate from 
period to period based upon the market demand for the capital 
we provide, our view of economic fundamentals including interest 
rates, the present mix of our Portfolio, our ability to identify new 
opportunities that meet our investment criteria, the volume of projects 
that have advanced to stages where we believe a transaction is 
appropriate, seasonality in our activities and in the various projects 
where we may provide debt or equity and our ability to consummate 
the identified opportunities, including as a result of our available 
capital. The level of our new origination activity, the percentage 
of the originations that we choose to retain on our balance sheet 
and the related income, will directly impact our interest and rental 
revenue and income from equity method investments.
40
HASI Form 10-K
Part II
Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Income from Securitization, Syndication and 
Other Services
We earn gain on sale of assets or fee income by securitizing or 
selling all or a portion of certain transactions. For transactions that 
we securitize via a non-consolidated trust, we recognize a gain 
on the securitization. The gain may be comprised of either or both 
cash received and a residual interest in securitized assets. We may 
also recognize additional income from servicing fees from these 
securitized assets over the life of the asset. We view the revenue 
from such activities as a valuable component of our earnings and 
an important source of franchise value.
In many cases, we arrange the securitization of the loan or other 
asset prior to originating the transaction and thus avoid exposure 
to credit spread and interest rate risks. In these cases, we avoid 
funding risks for these financings or other assets given that our 
securitization partners contractually agree to fund such assets before 
the origination transaction is completed.
We also generate fee income for syndications where we arrange 
financings that are held by other investors or if we sell existing 
transactions to other investors. In these transactions, unless we 
decide to hold a portion of the economic interest of the transaction 
on our balance sheet, we have no exposure to risks related to 
ownership of those financings. We may charge advisory, retainer 
or other fees, including through our broker dealer subsidiary and 
for our management services provided to co-investment structures. 
The total amount of income from securitizations, syndications, and 
other services will vary from quarter to quarter depending on various 
factors, including the level of our originations, the duration, credit 
quality and types of assets we originate, current and anticipated 
future interest rates, the impact on our leverage, the mix of our 
Portfolio and our need to tailor our mix of assets in order to maintain 
our exemption from registration under the 1940 Act.
Credit Risks
We source and identify quality opportunities within our broad areas 
of expertise and apply our rigorous underwriting processes to our 
transactions, which, we believe, will generally enable us to minimize 
our credit losses and maintain our current level of financing costs. 
In the case of various renewable energy and other sustainable 
infrastructure projects, we will be exposed to the credit risk of the 
obligor of the project’s PPA or other long-term contractual revenue 
commitments, as well as to the credit risk of certain suppliers and 
project operators. We are also exposed to credit risk in our other 
projects that do not benefit from governments as the obligor such as 
on balance sheet financing of projects undertaken by universities, 
schools and hospitals, as well as privately owned commercial 
projects. We have extended mezzanine loans to various special 
purpose entities which own residential or community solar projects, 
and the ultimate repayment of those loans is dependent on the 
creditworthiness of the related residential obligors. As a result of 
investing in these and other mezzanine loans, we are exposed to 
additional credit risk. In certain instances, interest is paid on our 
mezzanine loans in-kind, which increases our outstanding loan 
balances and causes the ultimate repayment of cash to occur later. 
While we do not anticipate facing significant credit risk in our assets 
related to government energy efficiency projects, we are subject to 
varying degrees of credit risk in these projects in relation to payment 
guarantees provided by ESCOs that are required in the event that 
certain energy savings are not realized by the customer. 
We seek to manage credit risk through thorough due diligence 
and underwriting processes, strong structural protections in our 
transaction agreements with customers and continual, active asset 
management and portfolio monitoring. Nevertheless, unanticipated 
credit losses could occur and during periods of economic downturn 
in the global economy, our exposure to credit risks from obligors 
increases, and our efforts to monitor and mitigate the associated 
risks may not be effective in reducing our credit losses. See Item 7A. 
Quantitative and Qualitative Disclosures about Credit Risks for 
further information on our credit risks and see Note 6 to our audited 
financial statements in this Form 10-K for additional detail of the 
credit risks surrounding our Portfolio.

Interest rate risk is highly sensitive to many factors, including 
governmental monetary and tax policies, domestic and international 
economic and political considerations and other factors beyond 
our control. We are subject to interest rate risk in connection with 
new asset originations and our borrowings, including our revolving 
credit facilities, and in the future, to the extent we choose to enter 
into any new floating rate assets, revolving credit facilities or other 
borrowings. See Item 7A. Quantitative and Qualitative Disclosures 
about Market Risk for further information on interest rates risks 
and liquidity. 
Commodity Prices
When we make investments in a project that is exposed to 
commodity prices, we may also be exposed to volatility in those 
prices. For example, the performance of renewable energy projects 
that produce electricity can be impacted by volatility in the market 
prices of various forms of energy, including electricity, coal and 
natural gas. This is especially true for utility scale projects that sell 
power on a wholesale basis such as many of our Grid-Connected 
projects as opposed to Behind-the-Meter projects which compete 
against the retail or delivered costs of electricity which includes the 
cost of transmitting and distributing the electricity to the end user. See 
Item 7A. Quantitative and Qualitative Disclosures about Market Risk 
for further information on the impact of commodity prices.
Government Policies
We make investments in renewable energy projects that typically 
depend in part on various federal, state or local governmental 
policies that support or enhance the project’s economic feasibility. 
Such policies may include governmental initiatives, laws and 
regulations designed to reduce energy usage and impact the 
use of renewable energy or the investment in, and the use of, 
41
HASI Form 10-K
Part II
Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

climate solutions. Policies and incentives provided by the U.S. 
federal government may include tax credits, tax deductions, 
bonus depreciation, federal grants and loan guarantees, and 
energy market regulations. The value of tax credits, deductions 
and incentives and how they can be realized may be impacted by 
changes in tax laws, rates, or regulations.
Incentives provided by state and local governments may include 
an RPS or similar clean energy standard, which specify the portion 
of the power utilized by local utilities that must be derived from 
renewable or clean energy sources. Additionally, certain states 
have implemented feed-in or net metering tariffs, pursuant to which 
electricity generated from renewable energy sources is purchased 
at a higher rate than prevailing wholesale rates. Other incentives 
include tariffs, tax incentives and other cash and non-cash payments.
Commercial entities, developers of climate solutions projects, 
and government agencies consider the impacts of these policies 
and incentives when making decisions on capital expenditures. 
Government regulations may also impact the terms of third party 
financing provided to support these projects. If any of these 
government policies, incentives or regulations are adversely 
amended, delayed, eliminated, reduced, retroactively changed 
or not extended beyond their current expiration dates or there is a 
negative impact from the recent federal law changes or proposals, 
the operating results of the projects we finance and the demand for, 
and the returns available from our investments may decline, which 
could harm our business.
Critical Accounting Policies and Use of Estimates
Our financial statements are prepared in accordance with GAAP, 
which requires the use of estimates and assumptions that involve 
the exercise of judgment and use of assumptions as to future 
uncertainties. The following discussion addresses the accounting 
policies that we use including areas that involve the use of significant 
estimates. Our most critical accounting policies involve decisions 
and assessments that could affect our reported assets and liabilities, 
as well as our reported revenues and expenses. We believe that the 
decisions and assessments upon which our financial statements are 
based are reasonable at the time made and based upon information 
available to us at that time. Our critical accounting policies and 
accounting estimates may be expanded over time. Those material 
accounting policies and estimates that we expect to be most critical 
to an investor’s understanding of our financial results and condition 
and require complex management judgment are discussed below. 
See Note 2 to our audited financial statements in this Form 10-K for 
further details on our accounting policies. We evaluate our critical 
accounting estimates and judgments on an ongoing basis and 
update them, as necessary, based on changing conditions.
We have identified the following accounting policies as critical 
because they require significant judgments and assumptions about 
highly complex and inherently uncertain matters and the use of 
reasonably different estimates and assumptions could have a 
material impact on our reported results of operations or financial 
condition. 
Consolidation 
We account for our investment in entities that are considered voting 
or variable interest entities under ASC 810, Consolidation. We 
perform an ongoing assessment as to whether each entry is a voting 
interest entity or a variable interest entity, and for variable interest 
entities, we make judgments to determine the primary beneficiary of 
each entity as required by ASC 810, which includes an assessment 
of the type and degree of control we have over the entity. If we 
would conclude that certain of these entities should be consolidated, 
we would include the entities’ assets, liabilities and related activity in 
our financial statements, along with non-controlling interests related 
to the ownership of the other equity holders. Refer to discussion 
below relating to additional consolidation considerations related 
to the securitization of receivables. We further discuss our process 
for evaluating these judgments in Note 2 to our audited financial 
statements in this Form 10-K.
Equity Method Investments
For our non-consolidated equity investments that we have concluded 
contain substantive profit sharing agreements, we generally 
determine our income allocations under the equity method of 
accounting based on the change in our claim on net assets of the 
investee entity as reported by the investee using a method commonly 
referred to as the hypothetical liquidation at book value method 
(“HLBV”). This method uses a hypothetical liquidation scenario 
based upon contractual liquidation provisions that may require 
judgment in its application and could have a material impact on our 
reported financial results. Any changes in this method of application 
or in certain assumptions could either increase or decrease our net 
income and the carrying value of the assets accounted for under 
this method. We further discuss our process for applying this method 
of income allocations in Note 2 to our audited financial statements 
in this Form 10-K.
Impairment of our Portfolio
We evaluate the various assets in our Portfolio on at least a quarterly 
basis, and more frequently when economic or other conditions 
warrant such an evaluation, for delinquencies or other events that 
may indicate a potential impairment or specific consideration in 
the development of the allowance for credit losses. For our equity 
method investments and real estate, if an impairment charge is 
deemed appropriate it would be recorded in our income statement 
and reduce our net income. For our receivables, we make judgments 
about our expected losses related to the receivables in our Portfolio 
and record an allowance for credit losses on such receivables with a 
provision for loss on receivables in our income statement. We further 
discuss our process for evaluating these judgments in Note 2 to our 
audited financial statements in this Form 10-K. 
42
HASI Form 10-K
Part II
Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Securitization of Financial Assets
We have established various special purpose entities or securitization 
trusts for the purpose of securitizing certain receivables or other debt 
investments. We make judgments, based in part, on supporting legal 
opinions, on whether these entities should be consolidated as a 
variable interest entity, as defined in ASC 810, Consolidation, and 
whether the transfers to these entities are accounted for as a sale of 
a financial asset or a secured borrowing under ASC 860, Transfers 
and Servicing. If we would conclude that certain of these special 
purpose entities or securitization trusts should be consolidated, we 
would include the assets and liabilities of the entity and their related 
activity in our financial statements. If sale accounting is not met 
in these transactions, it would be treated as a secured borrowing 
rather than a sale in our financial statements, which would result in 
reduced revenue in the period in which an asset contributed to the 
trust and an increase in assets and non-recourse debt. We further 
discuss our process for evaluating these judgments in Note 2 to 
our audited financial statements in this Form 10-K. We also make 
assumptions regarding the fair value of our securitization assets 
in these transferred assets. If our determination of fair value is 
determined to be incorrect, our gain on sale of receivables and 
investments in our income statement and securitization assets on 
our balance sheet will be inaccurate. See Note 3 to our audited 
financial statements in this Form 10-K for a discussion around fair 
value measurements. 
Results of Operations
For a comparison of our results of operations for the fiscal years 
ended December 31, 2023 and December 31, 2022, see 
“Part II, Item 7. Management’s Discussion and Analysis of Financial 
Condition and Results of Operations” of our annual report on Form 
10-K for the fiscal year ended December 31, 2023, filed with the 
SEC on February 21, 2023. 
We completed approximately $2.3 billion of transactions during 
both 2024 and 2023. Our strategy includes holding a large 
portion of these transactions on our balance sheet. We refer to the 
transactions we hold on our balance sheet as of a given date as 
our “Portfolio”. Our Portfolio was approximately $6.6 billion as of 
December 31, 2024 and $6.2 billion December 31, 2023.
Portfolio
Our Portfolio totaled approximately $6.6 billion as of December 31, 
2024, and included approximately $3.1 billion of BTM assets, 
approximately $2.6 billion of GC assets, and approximately 
$0.9 billion of FTN assets. Approximately 52% of our Portfolio 
consisted of unconsolidated equity investments in renewable energy 
related projects. Approximately 46% consisted of commercial 
and government receivables on our balance sheet, and the 
remainder of our Portfolio was real estate leased to renewable 
energy projects under long-term operating lease agreements. Our 
Portfolio consisted of over 550 transactions with an average size of 
$11 million and the weighted average remaining life of our Portfolio 
(excluding match-funded transactions) of approximately 16 years 
as of December 31, 2024.

• Net income increased by approximately $53 million as a result of 
a $107 million increase in income from equity method investments 
and a $64 million increase in total revenue, partially offset by a 
$79 million increase in total expense and a $39 million increase 
in income tax expense. These results do not include the Non-GAAP 
earnings adjustment related to equity method investments, which is 
discussed in the Non-GAAP Financial Measures section.
• Interest income and securitization asset income increased by $63 million 
due to a larger receivable portfolio and a larger securitization assets 
balance. Rental income decreased as a result of the deconsolidation of 
certain special purpose entities which held such land assets as a result 
of amendments to terms of the non-recourse debt held by those special 
purpose entities. See the table above for information on our average 
receivables, investment, and land balance and average yield on those 
assets. Gain on sale of assets increased by $12 million primarily due 
to a larger volume of assets being securitized. Other income increased 
by $8 million due to fees earned from asset management activities, 
including $5 million of fees earned related to our temporary role as 
service provider to special purpose vehicles in which we have invested 
that were previously sponsored by SunPower Corporation. In 2025, 
these services will be provided by an equity method investee we have 
formed with the replacement investor in those special purpose vehicles. 
• Interest expense for the year increased by approximately $71 million 
due to a higher average rate on a higher average debt balance. 
See the table above for detail on our average debt rate and 
average debt balance. Provision for loss on receivables decreased 
by $11 million compared to the prior period as a result of the 
release of certain loan specific reserves due to the contributions of 
loans to a co-investment structure and non-recurring prepayments, 
offset partially by provision on new loans and loan commitments.
• Compensation and benefits increased by $17 million as a result of 
an increase in our employee headcount and compensation. General 
and administrative increased by $2 million due to additional 
investment in corporate infrastructure. Included in compensation 
and benefits and general and administrative expenses for 2024 are 
$6 million of costs related to our temporary role as service provider 
to special purpose vehicles in which we have invested previously 
sponsored by SunPower Corporation. In 2025, these services will 
be provided by an equity method investee we have formed with 
the replacement investor in those special purpose vehicles. 
• Income from equity method investments increased by $107 million, 
primarily due to allocations of income in the current period related 
to tax credits allocated to our investors related to a grid-connected 
utility-scale solar project, as those tax credits reduced the tax equity 
investors ongoing claim on the net assets of the project. 
• Income tax expense increased by $39 million primarily due to an 
increase in our pre-tax book income.
Non-GAAP Financial Measures
We consider the following non-GAAP financial measures useful 
to investors as key supplemental measures of our performance: 
(1) adjusted earnings, (2) adjusted net investment income, 
(3) managed assets, and (4) adjusted cash from operations plus other 
portfolio collections. These non-GAAP financial measures should be 
45
HASI Form 10-K
Part II
Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

considered along with, but not as alternatives to, net income or loss as 
measures of our operating performance. These non-GAAP financial 
measures, as calculated by us, may not be comparable to similarly 
named financial measures as reported by other companies that do 
not define such terms exactly as we define such terms. 
Adjusted Earnings 
We calculate adjusted earnings as GAAP net income (loss) excluding 
non-cash equity compensation expense, provisions for loss on 
receivables, amortization of intangibles, non-cash provision (benefit) 
for taxes, losses or (gains) from modification or extinguishment of 
debt facilities, any one-time acquisition related costs or non-cash tax 
charges and the earnings attributable to our non-controlling interest of 
our Operating Partnership. We also make an adjustment to eliminate 
our portion of fees we earn from related-party co-investment structures, 
and for our equity method investments in the renewable energy 
projects as described below. We will use judgment in determining 
when we will reflect the losses on receivables in our adjusted earnings 
and will consider certain circumstances such as the time period in 
default, sufficiency of collateral as well as the outcomes of any related 
litigation. In the future, adjusted earnings may also exclude one-time 
events pursuant to changes in GAAP and certain other adjustments as 
approved by a majority of our independent directors. Prior to 2024, 
we referred to this metric as distributable earnings.
We believe a non-GAAP measure, such as adjusted earnings, that 
adjusts for the items discussed above is and has been a meaningful 
indicator of our economic performance in any one period and is 
useful to our investors as well as management in evaluating our 
performance as it relates to expected dividend payments over 
time. Additionally, we believe that our investors also use adjusted 
earnings, or a comparable supplemental performance measure, to 
evaluate and compare our performance to that of our peers, and as 
such, we believe that the disclosure of adjusted earnings is useful to 
our investors.
Certain of our equity method investments in renewable energy and 
energy efficiency projects are structured using typical partnership 
“flip” structures where the investors with cash distribution preferences 
receive a pre-negotiated return consisting of priority distributions 
from the project cash flows, in many cases, along with tax attributes. 
Once this preferred return is achieved, the partnership “flips” and the 
common equity investor, often the operator or sponsor of the project, 
receives more of the cash flows through its equity interests while the 
previously preferred investors retain an ongoing residual interest. We 
have made investments in both the preferred and common equity 
of these structures. Regardless of the nature of our equity interest, 
we typically negotiate the purchase prices of our equity investments, 
which have a finite expected life, based on our underwritten project 
cash flows discounted back to the net present value, based on a 
target investment rate, with the cash flows to be received in the future 
reflecting both a return on the capital (at the investment rate) and 
a return of the capital we have committed to the project. We use a 
similar approach in the underwriting of our receivables.
Under GAAP, we account for these equity method investments 
utilizing the HLBV method. Under this method, we recognize income 
or loss based on the change in the amount each partner would 
receive, typically based on the negotiated profit and loss allocation, 
if the assets were liquidated at book value, after adjusting for any 
distributions or contributions made during such quarter. The HLBV 
allocations of income or loss may be impacted by the receipt of tax 
attributes, as tax equity investors are allocated losses in proportion 
to the tax benefits received, while the sponsors of the project are 
allocated gains of a similar amount. The investment tax credit available 
for election in solar projects is a one-time credit realized in the quarter 
when the project is considered operational for tax purposes and is 
fully allocated under HLBV in that quarter (subject to an impairment 
test), while the production tax credit required for wind projects and 
electable for solar projects is a ten-year credit and thus is allocated 
under HLBV over a ten year period. In addition, the agreed upon 
allocations of the project’s cash flows may differ materially from the 
profit and loss allocation used for the HLBV calculations in a given 
period. We also consider the impact of any OTTI in determining our 
income from equity method investments.
The cash distributions for those equity method investments where we 
apply HLBV are segregated into a return on and return of capital 
on our cash flow statement based on the cumulative income (loss) 
that has been allocated using the HLBV method. However, as a 
result of the application of the HLBV method, including the impact of 
tax allocations, the high levels of depreciation and other non-cash 
expenses that are common to renewable energy projects and the 
differences between the agreed upon profit and loss and the cash 
flow allocations, the distributions and thus the economic returns (i.e. 
return on capital) achieved from the investment are often significantly 
different from the income or loss that is allocated to us under the HLBV 
method in any one period. Thus, in calculating adjusted earnings, 
for certain of these investments where there are characteristics as 
described above, we further adjust GAAP net income (loss) to take 
into account our calculation of the return on capital (based upon the 
underwritten investment rate), as adjusted to reflect the performance 
of the project and the cash distributed. We believe this equity method 
investment adjustment to our GAAP net income (loss) in calculating 
our adjusted earnings measure is an important supplement to the 
income (loss) from equity method investments as determined under 
GAAP for an investor to understand the economic performance of 
these investments where HLBV income can differ substantially from 
the economic returns in any one period.

Adjusted earnings does not represent cash generated from operating 
activities in accordance with GAAP and should not be considered 
as an alternative to net income (determined in accordance with 
GAAP), or an indication of our cash flow from operating activities 
(determined in accordance with GAAP), or a measure of our liquidity, 
or an indication of funds available to fund our cash needs, including 
our ability to make cash distributions. In addition, our methodology 
for calculating adjusted earnings may differ from the methodologies 
employed by other companies to calculate the same or similar 
supplemental performance measures, and accordingly, our reported 
adjusted earnings may not be comparable to similar metrics reported 
by other companies.
We have calculated our adjusted earnings for the years ended December 31, 2024, 2023 and 2022. The table below provides a

(1)
The per share data reflects the GAAP diluted earnings per share and is the most comparable GAAP measure to our Adjusted earnings per share. 
(2)
This is a non-GAAP adjustment to reflect the return on capital of our equity method investments as described above.
(3)
This adjustment is to eliminate the intercompany portion of fees received from co-investment structures that for GAAP net income is included in the Equity method income line item. Since we 
remove GAAP Equity method income for purposes of our Adjusted earnings metric, we add back the elimination through this adjustment.
(4)
In addition to these provisions, in 2022 we wrote off two commercial receivables with a combined total carrying value of approximately $8 million which represented assignments of land 
lease payments from two wind projects that we had originated in 2014 as a part of an acquisition of a large land portfolio. In 2017, the operator of the projects terminated the lease, at which 
time we filed a legal claim and placed these assets on non-accrual status. In 2019, we received a court decision indicating that the owners of the projects were within their rights under the 
contract terms to terminate the lease which impacts the land lease assignments to us, at which time we reserved the receivables for their full carrying amount. In 2022, we received a court 
decision indicating that our appeal was not successful, and accordingly wrote off the full amount of the receivable. We have excluded the write-off from Adjusted earnings for the year ended 
December 31, 2022, due to the infrequent occurrence of credit losses as well as the unique nature of the receivables, as the assignment of land lease payments from wind projects represent a 
small portion of our total portfolio. In 2024, we concluded that an equity method investment, along with certain loans we had made to this investee, were not recoverable. The equity method 
investment and loans had a carrying value of $0 due to the losses already recognized through GAAP income from equity method investments as a result of operating losses sustained by 
the investee. We have excluded this write-off from Adjusted earnings, as this investment was an investment in a corporate entity which is not a part of our current investment strategy and is 
immaterial to our Portfolio. The loss associated with these investments is included in our Average Annual Realized Loss on Managed Assets metric disclosed below. 
(5)
Shares used to calculated Adjusted earnings per share represents the weighted average number of shares outstanding including our issued unrestricted common shares, restricted stock awards, 
restricted stock units, long-term incentive plan units, and the non-controlling interest in our Operating Partnership. We include any potential common stock issuances related to share based 
compensation units in the amount we believe is reasonably certain to vest. As it relates to Convertible Notes, we will assess the market characteristics around the instrument to determine if it is more 
akin to debt or equity based on the value of the underlying shares compared to the conversion price. If the instrument is more debt-like then we will include any related interest expense and exclude 
the underlying shares issuable upon conversion of the instrument. If the instrument is more equity-like and is more dilutive when treated as equity then we will exclude any related interest expense 
and include the weighted average shares underlying the instrument. We will consider the impact of any capped calls in assessing whether an instrument is equity-like or debt like.
Adjusted Net Investment Income 
We have a portfolio of investments that we finance using a combination of debt and equity. We calculate adjusted net investment income 
as shown in the table below by adjusting GAAP-based net investment income for those earnings adjustments that are applicable to adjusted 
net investment income. We believe that this measure is useful to investors as it shows the recurring income generated by our Portfolio after the 
associated interest cost of debt financing. Our management also uses adjusted net investment income in this way. Our non-GAAP adjusted 
net investment income measure may not be comparable to similarly titled measures used by other companies. For further information on 
the adjustments between GAAP-based net investment income and adjusted net investment income, see the discussion above related to 
Adjusted Earnings. Prior to 2024, we referred to this measure as distributable net investment income.
The following is a reconciliation of our GAAP-based net investment income to our adjusted net investment income for the years ended 
December 31, 2024, 2023 and 2022:

Managed Assets
As we consolidate assets on our balance sheet, securitize assets 
off-balance sheet, and manage asset in which we coinvest with 
other parties, certain receivables and other assets are not reflected 
on our balance sheet where we may have a residual interest in the 
performance of the investment, such as a retained interest in cash 
flows. Thus, we present our investments on a non-GAAP “Managed 
Assets” basis. We believe that our Managed Asset information is 
useful to investors because it portrays the amount of both on- and 
off-balance sheet assets that we manage, which enables investors 
to understand and evaluate the credit performance associated 
with our portfolio of receivables, equity investments, and residual 
assets in off-balance sheet assets. Our management also uses 
Managed Assets in this way. Our non-GAAP Managed Assets 
measure may not be comparable to similarly titled measures used 
by other companies. 
The following is a reconciliation of our GAAP-based Portfolio to our Managed Assets as of December 31, 2024 and 2023:

Adjusted Cash Flow from Operations Plus Other 
Portfolio Collections
We operate our business in a manner that considers total cash 
collected from our portfolio and making necessary operating 
and debt service payments to assess the amount of cash we have 
available to fund dividends and investments. We believe that the 
aggregate of these items, which combine as a non-GAAP financial 
measure titled Adjusted Cash Flow from Operations plus Other 
Portfolio Collections, is a useful measure of the liquidity we have 
available from our assets to fund both new investments and our 
regular quarterly dividends. This non-GAAP financial measure may 
not be comparable to similarly titled or other similar measures used 
by other companies. Although there is also not a directly comparable 
GAAP measure that demonstrates how we consider cash available 
for dividend payment, below is a reconciliation of this measure to 
Net cash provided by operating activities.
Also, Adjusted Cash Flow from Operations plus Other Portfolio 
Collections differs from Net cash provided by (used in) investing 
activities in that it excludes many of the uses of cash used in our 
investing activities such as Equity method investments, Purchases 
of and investments in receivables, Purchases of investments, and 
Collateral provided to and received from hedge counterparties. In 
addition, Adjusted Cash Flow from Operations plus Other Portfolio 
Collections is not comparable to Net cash provided by (used in) 
financing activities in that it excludes many of our financing activities 
such as proceeds from common stock issuances and borrowings and 
repayments of unsecured debt.
Cash available for reinvestment is a non-GAAP measure which is 
calculated as adjusted cash flow from operations plus other portfolio 
collections less dividend and distribution payments made during 
the period. We believe Cash available for reinvestment is useful 
as a measure of our ability to make incremental investments from 
reinvested capital after factoring in all necessary cash outflows 
to operate the business. Management uses Cash available for 
reinvestment in this way, and we believe that our investors use it in 
a similar fashion.

Other Measures and Metrics
Average Annual Realized Loss on Managed Assets 
Average Annual Realized Loss on Managed Assets represents the 
average annual rate of our incurred losses, calculated as the amount 
of realized losses incurred in each year as a percentage of each year’s 
average annual Managed Assets. This metric is calculated on the ten 
year period ending December 31, 2024. Incurred losses include 
both realized losses on equity method investments and realized credit 
losses on receivables and investments. Although there is not a direct 
comparable GAAP measure, we have presented average annual 
recognized loss on Managed Assets as calculated under GAAP for 
comparison. Average Annual Realized Loss on Managed Assets differs 
from average annual recognized loss on Managed Assets as calculated 
under GAAP as the timing is based on realization of loss rather than 
GAAP recognition. We believe that Average Annual Realized Loss 
on Managed Assets provides an additional metric for assessing our 
underwriting quality over our history of investing in climate solutions. 
Our management uses it in this way and we believe that our investors 
use it in a similar fashion to evaluate our investment performance, and 
as such, we believe that its disclosure is useful to our investors. The table 
below shows these metrics as of December 31, 2024 is:

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Portfolio Yield 
We calculate portfolio yield as the weighted average underwritten 
yield of the investments in our Portfolio as of the end of the period. 
Underwritten yield is the rate at which we discount the expected cash 
flows from the assets in our Portfolio to determine our purchase price. 
In calculating underwritten yield, we make certain assumptions, 
including the timing and amounts of cash flows generated by our 
investments, which may differ from actual results, and may update 
this yield to reflect our most current estimates of project performance. 
We believe that portfolio yield provides an additional metric to 
understand certain characteristics of our Portfolio as of a point 
in time. Our management uses portfolio yield this way and we 
believe that our investors use it in a similar fashion to evaluate 
certain characteristics of our Portfolio compared to our peers, and 
as such, we believe that the disclosure of portfolio yield is useful 
to our investors.
Our Portfolio totaled approximately $6.6 billion as of December 31, 
2024. Unlevered portfolio yield was 8.3% as of December 31, 2024 and 
7.9% as of December 31, 2023. See Note 6 to our financial statements 
and MD&A - Our Business in this Form 10-K for additional discussion of 
the characteristics of our Portfolio as of December 31, 2024.
Human Capital Metrics
As part of our broader human capital strategy, we monitor and 
disclose certain metrics which help us understand our workforce. 
As of December 31, 2024, we employed 153 people full-time, 
5 people part-time, and 11 people as independent contractors. The 
average tenure of our employees as of December 31, 2024, was 
approximately 4.5 years, and more than 40% of our employees 
had been employed by us for more than 4 years. For the year ended 
December 31, 2024, we had a voluntary employee turnover rate 
of 5%. There were no retirements or resignations related to ill health. 
As discussed in Item 1. Business - Human Capital Strategy, 
we believe that fostering an internal culture of belonging that is 
supportive and allows people of all background to flourish lends 
itself to the highest levels of company performance and facilitates the 
attraction and retention of best-in-class talent. We track and report 
internally on key talent metrics including workforce demographics, 
critical role pipeline data, diversity data, and engagement and 
inclusion metrics. These metrics are actively managed and reported 
to our executive leadership as well as our Board. 
In addition to diversity of gender and ethnic background, we also 
value diversity of thought, with 54% of our leadership team and 
70% of our Board possessing degrees outside the fields of business 
or economics, including in science and engineering, liberal and 
fine arts, and law. 
Liquidity and Capital Resources
Liquidity is a measure of our ability to meet potential short term 
(within one year) and long term cash requirements. We carefully 
manage and forecast our liquidity sources and uses on a frequent 
basis. Our sources of liquidity typically include collections from 
our Portfolio, cash proceeds from asset sales and securitizations, 
fee revenue, proceeds from debt transactions, and proceeds from 
equity transactions. Our uses of liquidity typically include funding 
investments, operating expenses (including cash compensation), 
interest and principal payments on our debt, stockholder dividends 
and limited partner distributions, and funding investments. 
We typically pay our operating expenses, our debt service, and 
dividends from collections on our Portfolio and proceeds from sales 
of Portfolio investments. We use borrowings as part of our financing 
strategy to increase potential returns to our stockholders and have 
available to us a broad range of financing sources. We finance our 
investments primarily with non-recourse or recourse debt, equity and 
off-balance sheet securitization or co-investment structures.
We maintain sufficiently available liquidity in the form of unrestricted 
cash and immediately available capacity on our credit facilities to 
manage our net cash flow. Below is a summary of our available 
liquidity by source:

Capital markets activity during the year ended 
December 31, 2024
During the year ended December 31, 2024, we increased the 
available capacity available under our unsecured revolving credit 
facility to $1.35 billion, and extended the maturity of the facility 
to April 2028. We also extended the maturity of our unsecured 
term loan facility to April 2027, and used borrowings from the 
unsecured revolving credit facility to partially prepay our unsecured 
term loan facility by $275 million. We also increased the available 
capacity under our credit-enhanced green commercial paper notes 
program to $125 million, and extended the term of the facility 
to April 2026. We established a senior secured credit facility, 
designed to warehouse qualifying climate solutions assets until they 
achieve key technical milestones, at which point we may consider 
them for sale to large institutional investors under our established 
securitization programs. The capacity of this senior secured credit 
facility is $100 million, subject to the amount of pledged collateral. 
In December of 2024, we launched a stand-alone commercial 
paper notes program, whereby we can issue commercial paper 
notes up to the lesser of the amount of available capacity currently 
existing under our unsecured credit facility or $1 billion. 
During the year ended December 31, 2024, we issued an additional 
$200 million principal amount of 2027 Senior Unsecured Notes for 
proceeds of $204 million, and issued $94 million of non-recourse 
debt secured by equity method investments. We also issued $1 billion 
of senior unsecured notes due 2034, and used $400 million of the 
net proceeds from such offering to redeem our 6.00% Senior Notes 
due 2025, and the remainder to temporarily repay a portion of the 
outstanding borrowings under our unsecured revolving credit facility. 
We also issued $204 million in equity during 2024. 
As discussed in Note 8 to our financial statements in this Form 10-K, 
we entered into a strategic partnership with KKR called CarbonCount 
Holdings 1, LLC (“CCH1”), under which we each have committed to 
invest $1 billion in climate solutions projects over an 18 month period. 
Maturities of recourse debt obligations
In addition to general operational obligations, which are typically 
paid as incurred, and dividends and distributions, which are declared 
by our Board quarterly, we have future cash needs related to the 
payments due at maturity of our Senior Unsecured Notes and our 
term loan facilities, and the balances of our short-term commercial 
paper programs and our revolving credit facilities. We also have 
maturities related to our non-recourse debt and Convertible Notes. 
However, as it relates to the non-recourse debt, to the extent there 
are not sufficient cash flows received from investments pledged 
as collateral for such debt, the investor has no recourse against 
other corporate assets to recover any shortfalls and corporate cash 
contributions would not be required. As it relates to the Convertible 
Notes, those obligations may be settled at maturity with cash, or 
with the issuance of shares to the extent that the market price of our 
common stock exceeds the strike price on our Convertible Notes. 
For further information on our long-term debt, see Note 8 to our 
financial statements of this Form 10-K.

Additional borrowings and financial leverage management 
As a means of financing our business, we plan to continue to issue debt 
which may be either recourse or non-recourse and either fixed-rate 
or floating-rate and may issue additional equity. We also expect to 
use both on-balance sheet and off-balance sheet securitizations. We 
also use separately funded special purpose entities or co-investment 
vehicles to allow us to expand the investments that we make or to 
manage Portfolio diversification.
The decision as to how we finance specific assets or groups of assets 
is largely driven by risk and portfolio and financial management 
considerations, including the potential for gain on sale or fee income, 
as well as the overall interest rate environment, prevailing credit spreads, 
the terms of available financing, and financial market conditions. During 
periods of market disruptions, certain sources of financing may be 
more readily accessible than others which may impact our financing 
decisions. Over time, as market conditions change, we may use other 
forms of debt and equity in addition to these financing arrangements.
The amount of financial leverage we may deploy for particular assets 
will depend upon our target capital structure and the availability of 
particular types of financing and our assessment of the credit, liquidity, 
price volatility and other risks of such assets, and the interest rate 
environment. As shown in the table below, our debt to equity ratio 
was approximately 1.8 to 1 as of December 31, 2024, which is 
below our current Board-approved leverage limit of up to 2.5 to 1. 
Our percentage of fixed rate debt including the impact of our interest 
rate derivatives was approximately 100% as of December 31, 2024, 
which is at the top of our Board-approved targeted fixed rate debt 
percentage range of 75% to 100%. Our targeted fixed rate debt 
range allows for percentages as low as 70% on a short term basis if 
we intend to repay or swap floating rate borrowings in the near term.

Floating-rate borrowings include borrowings under our floating-rate credit facilities and commercial paper issuances with less than six months original maturity, to the extent such borrowings 
are not hedged using interest rate swaps.
(2)
Fixed-rate debt includes the impact of our interest rate swaps and collars on debt that is otherwise floating. Debt excludes securitizations that are not consolidated on our balance sheet. 
We intend to use financial leverage for the primary purpose of 
financing our Portfolio and business activities and not for the 
purpose of speculating on changes in interest rates. While we may 
temporarily exceed the leverage limit, if our Board approves a 
material change to this limit, we anticipate advising our stockholders 
of this change through disclosure in our periodic reports and other 
filings under the Exchange Act.
While we generally intend to hold our target assets that we do 
not securitize upon acquisition as long term investments, certain of 
our investments may be sold in order to manage our interest rate 
risk and liquidity needs, to meet other operating objectives and to 
adapt to market conditions. The timing and impact of future sales 
of receivables and investments, if any, cannot be predicted with 
any certainty. 
We or our affiliates may, at any time and from time to time, seek 
to retire or purchase our outstanding debt through cash purchases 
and/or exchanges for equity or debt, in open-market purchases, 
privately negotiated transactions or otherwise. Such repurchases or 
exchanges, if any, will be upon such terms and at such prices as we 
may determine, and will depend on prevailing market conditions, 
our liquidity requirements, contractual restrictions and other factors. 
The amounts involved may be material.
We believe our identified sources of liquidity will be adequate for 
purposes of meeting our short-term and long-term liquidity needs, 
which include funding future investments, debt service, operating 
costs and distributions to our stockholders.
Sources and Uses of Cash
We had approximately $150 million and $75 million in unrestricted 
cash, cash equivalents, and restricted cash as of December 31, 
2024 and 2023, respectively. The following table summarizes 
our cash flows for the years ended December 31, 2024, 2023,

more from the sale of receivables, and collected $403 million additional 
in principal collections from receivables, driven primarily by a large 
prepayment in 2024. 
Discussion of significant changes in cash provided by 
financing activities
Net cash provided by financing activities for the year ended 
December 31, 2024 was $1.6 billion lower than the year ended 
December 31, 2023. Net credit facility activity was $750 million 
lower than in the prior year. We issued $115 million less in term 
loans in the current year, and made $551 million additional term 
loan payments. We issued $289 million less common stock in the 
current period. We had a net $221 million cash inflow related to the

issuance and repayments of convertible notes and related capped 
call purchase in 2023 which did not recur in the current period. 
Hedging collateral financing activities provided $39 million more 
in 2024 than in 2023. 
Supplemental Guarantor Information
The Company and each of Hannon Armstrong Sustainable 
Infrastructure, L.P., Hannon Armstrong Capital, LLC. HAC 
Holdings I LLC, HAC Holdings II LLC, HAT Holdings I LLC and HAT 
Holdings II LLC (the “Subsidiary Guarantors”) have filed a shelf 
registration statement on Form S-3 with the SEC pursuant to which 
the Company may offer and sell debt securities from time to time and 
such securities may be guaranteed by the Subsidiary Guarantors. 
The Subsidiary Guarantors are consolidated in the Company’s 
Consolidated Financial Statements and separate Consolidated 
Financial Statements of the Subsidiary Guarantors have not 
been presented in accordance with Rule 3-10 of Regulation S-X. 
Furthermore, as permitted under Rule 13-01(a)(4)(vi), the Company 
has excluded the summarized financial information for the Subsidiary 
Guarantors as the assets, liabilities and results of operations of the 
Company and the Subsidiary Guarantors are not materially different 
than the corresponding amounts presented in the Consolidated 
Financial Statements of the Company, and management believes 
such summarized financial information would be repetitive and not 
provide incremental value to investors.
Off-Balance Sheet Arrangements 
We have relationships with non-consolidated entities or financial 
partnerships, such as entities often referred to as structured investment 
vehicles, or special purpose or variable interest entities, established 
to facilitate the sale of securitized assets. Other than our securitization 
assets (including any outstanding servicer advances) of approximately 
$263 million as of December 31, 2024, that may be at risk in the event 
of defaults or prepayments in our securitization trusts and as discussed 
below, and except as disclosed in Note 9 to our audited financial 
statements in this Form 10-K, we have not guaranteed any obligations 
of non-consolidated entities or entered into any commitment or intent 
to provide additional funding to any such entities. A more detailed 
description of our relations with non-consolidated entities can be 
found in Note 2 of our audited financial statements in this Form 10-K. 
In connection with some of our transactions, we have provided 
certain limited guarantees to other transaction participants covering 
the accuracy of certain limited representations, warranties or 
covenants and provided an indemnity against certain losses from 
“bad acts” including fraud, failure to disclose a material fact, theft, 
misappropriation, voluntary bankruptcy or unauthorized transfers. 
In some transactions, we have also guaranteed our compliance 
with certain tax matters, such as negatively impacting the investment 
tax credit and certain other obligations in the event of a change in 
ownership or our exercising certain protective rights.
Dividends
Any distributions we make will be at the discretion of our Board and 
will depend upon, among other things, our actual results of operations. 
These results and our ability to pay distributions will be affected by 
various factors, including the net interest and other income from our 
assets, our operating expenses and any other expenditures. In the 
event that our Board determines to make distributions in excess of 
the income or cash flow generated from our assets, we may make 
such distributions from the proceeds of future offerings of equity or 
debt securities or other forms of debt financing or the sale of assets. 
Our Board had approved of our revocation of our REIT status effective 
for tax year 2024. We elected to be taxed as a REIT during tax 
years 2023 and previous. U.S. federal income tax law generally 
requires that a REIT distribute annually at least 90% of its REIT taxable 
income, without regard to the deduction for dividends paid and 
excluding net capital gains, and that it pays tax at regular corporate 
rates to the extent that it annually distributes less than 100% of its REIT 
taxable income. As a REIT, we paid quarterly distributions, which on 
an annual basis equaled or exceeded substantially all of our REIT 
taxable income. The taxable income of the REIT would vary from our 
GAAP earnings due to a number of different factors including the 
book to tax timing differences of income and expense recognition 
from our transactions as well as the amount of taxable income of our 
TRS distributed to the REIT. See Note 10 to our financial statements 
in this Form 10-K regarding the amount of our distributions that are 
treated as ordinary taxable income to our stockholders.
The dividends declared in 2024 and 2023 are described in Note 11 
to our audited financial statements in this Form 10-K.
Book Value Considerations
As of December 31, 2024, we carried only our investments, residual 
assets in securitized financial assets, and our derivatives at fair value 
on our balance sheet. As a result, in reviewing our book value, there 
are a number of important factors and limitations to consider. Other 
than our investments, the residual assets in securitized financial 
assets, and derivatives that are carried on our balance sheet at fair 
value as of December 31, 2024, the carrying value of our remaining 
assets and liabilities are calculated as of a particular point in time, 
which is largely determined at the time such assets and liabilities 
were added to our balance sheet using a cost basis in accordance 
54
HASI Form 10-K
Part II
Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

with GAAP, adjusted for income or loss recognized on such assets. 
Other than the allowance for current expected credit losses applied 
to our receivables, our remaining assets and liabilities do not 
incorporate other factors that may have a significant impact on their 
value, most notably any impact of business activities, changes in 
estimates, or changes in general economic conditions, interest rates 
or commodity prices since the dates the assets or liabilities were 
initially recorded. Accordingly, our book value does not necessarily 
represent an estimate of our net realizable value, liquidation value 
or our fair market value.
Item 7A. Quantitative and Qualitative Disclosures about Market Risk
We anticipate that our primary market risks will be related to the credit quality of our counterparties and project companies, market interest 
rates, the liquidity of our assets, commodity prices and environmental factors. We will seek to manage these risks while, at the same time, 
seeking to provide an opportunity to stockholders to realize attractive returns through ownership of our common stock. 
Credit Risks
We source and identify quality opportunities within our broad areas 
of expertise and apply our rigorous underwriting processes to our 
transactions, which, we believe, will generally enable us to minimize 
our credit losses and maintain access to attractive financing. Through 
our investments in various projects, we will be exposed to the credit 
risk of the obligor of the project’s PPA or other long-term contractual 
revenue commitments, as well as to the credit risk of certain suppliers 
and project operators. We are exposed to credit risk in our other 
projects that do not benefit from governments as the obligor such as 
on balance sheet financing of projects undertaken by universities, 
schools and hospitals, as well as privately owned commercial 
projects. While we do not anticipate facing significant credit risk in 
our assets related to government energy efficiency projects, we are 
subject to varying degrees of credit risk in these projects in relation 
to guarantees provided by ESCOs where payments under energy 
savings performance contracts are contingent upon achieving 
pre-determined levels of energy savings. We have invested in 
mezzanine loans and, as a result, we are exposed to additional 
credit risk. We seek to manage credit risk through thorough due 
diligence and underwriting processes, strong structural protections 
in our transaction agreements with customers and continual, 
active asset management and portfolio monitoring. Nevertheless, 
unanticipated credit losses could occur and during periods of 
economic downturn in the global economy, our exposure to credit 
risks from obligors increases, and our efforts to monitor and mitigate 
the associated risks may not be effective in reducing our credit risks.
We use a risk rating system to evaluate projects that we target. We 
first evaluate the credit rating of the offtakers or counterparties to the 
project using an average of the external credit ratings for an obligor, 
if available, or an estimated internal rating based on a third-party 
credit scoring system. We then estimate the probability of default and 
estimated recovery rate based on the obligors’ credit ratings and 
the terms of the contract. We also review the performance of each 
investment, including through, as appropriate, a review of project 
performance, monthly payment activity and active compliance 
monitoring, regular communications with project management and, 
as applicable, its obligors, sponsors and owners, monitoring the 
financial performance of the collateral, periodic property visits and 
monitoring cash management and reserve accounts. The results of 
our reviews are used to update the project’s risk rating as necessary. 
Additional detail of the credit risks surrounding our Portfolio can be 
found in Note 6 to our financial statements in this Form 10-K.
Interest Rate and Borrowing Risks
Interest rate risk is highly sensitive to many factors, including 
governmental monetary and tax policies, domestic and international 
economic and political considerations and other factors beyond 
our control.
We are subject to interest rate risk in connection with new asset 
originations and our floating-rate borrowings, and in the future, any 
new floating rate assets, credit facilities or other borrowings. Because 
short-term borrowings are generally short-term commitments of 
capital, lenders may respond to market conditions, making it more 
difficult for us to secure continued financing. If we are not able to 
renew our then existing borrowings or arrange for new financing 
on terms acceptable to us, or if we default on our covenants or are 
otherwise unable to access funds under any of these borrowings, 
we may have to curtail our origination of new assets and/or 
dispose of assets. We face particular risk in this regard given that 
we expect many of our borrowings will have a shorter duration 
than the assets they finance. Increasing interest rates may reduce 
the demand for our investments while declining interest rates may 
increase the demand. Both our current and future revolving credit 
facilities and other borrowings may be of limited duration and are 
periodically refinanced at then current market rates. We attempt to 
reduce interest rate risks and to minimize exposure to interest rate 
fluctuations through the use of fixed rate financing structures, when 
appropriate, whereby we seek to (1) match the maturities of our 
debt obligations with the maturities of our assets, (2) borrow at fixed 
rates for a period of time or (3) match the interest rates on our assets 
with like-kind debt (i.e., we may finance floating rate assets with 
floating rate debt and fixed-rate assets with fixed-rate debt), directly 
55
HASI Form 10-K
Part II
Item 7A. Quantitative and Qualitative Disclosures about Market Risk

or through the use of interest rate swap agreements, interest rate cap 
agreements or other financial instruments, or through a combination 
of these strategies. We expect these instruments will allow us to 
minimize, but not eliminate, the risk that we must refinance our 
liabilities before the maturities of our assets and to reduce the impact 
of changing interest rates on our earnings. In addition to the use of 
traditional derivative instruments, we also seek to mitigate interest 
rate risk by using securitizations, syndications and other techniques 
to construct a portfolio with a staggered maturity profile. We monitor 
the impact of interest rate changes on the market for new originations 
and often have the flexibility to negotiate the term of our investments 
to offset interest rate increases.
Typically, our long-term debt, or that of the projects in which we 
invest if applicable, is at fixed rates or may at times be fixed using 
interest rate hedges that convert most of the floating rate debt to 
fixed rate debt. If interest rates rise, and our fixed rate debt balance 
remains constant, we expect the fair value of our fixed rate debt 
to decrease and the value of any hedges on floating rate debt to 
increase. See Note 3 to our audited financial statements in this 
Form 10-K for the estimated fair value of our fixed rate long-term 
debt, which is based on having the same debt service requirements 
that could have been borrowed at the date presented, at prevailing 
current market interest rates. 
Our unsecured term loan is a variable rate loan with an 
outstanding balance of $247 million as of December 31, 2024, 
and our revolving credit facilities are variable rate lines of credit. 
We also have short-term green commercial paper borrowings 
outstanding of $100 million, which we may refinance through the 
issuance of additional paper at the then prevailing short-term rate. 
Increases in interest rates would result in higher interest expense 
while decreases in interest rates would result in lower interest 
expense. As described above, we may use various financing 
techniques including interest rate swap agreements, interest rate 
cap agreements or other financial instruments, or a combination 
of these strategies to mitigate the variable interest nature of these 
facilities, and have $618 million notional value of interest rate 
swaps to hedge these floating-rate borrowings. An increase in 
benchmark interest rates would not increase the quarterly interest 
expense related to our variable rate borrowings as a result of these 
interest rate swaps. Such hypothetical impact of interest rates on 
our variable rate borrowings does not consider the effect of any 
change in overall economic activity that could occur in a rising 
interest rate environment. Further, in the event of such a change in 
interest rates, we may take actions to further mitigate our exposure 
to such a change. However, due to the uncertainty of the specific 
actions that would be taken and their possible effects, the analysis 
assumes no changes in our financial structure.
We record certain of our assets at fair value in our financial 
statements and any changes in the discount rate would impact 
the value of these assets. See Note 3 to our audited financial 
statements in this Form 10-K.
Liquidity and Concentration Risk
The assets that comprise our Portfolio are not and are not expected to 
be publicly traded. A portion of these assets may be subject to legal 
and other restrictions on resale or will otherwise be less liquid than 
publicly-traded securities. The illiquidity of our assets may make it 
difficult for us to sell such assets if the need or desire arises, including 
in response to changes in economic and other conditions. Many of our 
assets, or the collateral supporting those assets, are concentrated in 
certain geographic areas and markets, which may make those assets 
or the related collateral more susceptible to market or environmental 
disruptions. As it relates to environmental risks, when we underwrite 
and structure our investments the environmental risks and opportunities 
are an integral consideration to our investment parameters. See also 
“Credit Risks” discussed above.
Commodity and Environmental Attribute Price Risk
When we make equity or debt investments for a renewable energy 
project that acts as a substitute for an underlying commodity, we 
may be exposed to volatility in prices for that commodity. The 
performance of renewable energy projects that produce electricity 
or natural gas can be impacted by volatility in the market prices of 
various forms of energy, including electricity, coal and natural gas. 
This is especially true for GC utility scale projects that sell power 
on a wholesale basis as opposed to BTM projects which compete 
against the retail or delivered costs of electricity which includes the 
cost of transmitting and distributing the electricity to the end user. 
Projects in which we invest, or in which we may plan to invest, may 
also be exposed to volatility in the prices of environmental attributes 
which the project may produce.
Although we generally focus on renewable energy projects that 
have the majority of their operating cash flow supported by 
long-term PPAs or leases, many of our projects have shorter term 
contracts (which may have the potential of producing higher current 
returns) or sell their power, energy or environmental attributes in 
the open market on a merchant basis. The cash flows of certain 
projects, and thus the repayment of, or the returns available for, our 
assets, are subject to risk if energy or environmental attribute prices 
change. We also attempt to mitigate our exposure through structural 
protections. These structural protections, which are typically in the 
form of a preferred return or cash sweep mechanism, are designed 
to allow recovery of our capital and an acceptable return over time. 
When structuring and underwriting these transactions, we evaluate 
56
HASI Form 10-K
Part II
Item 7A. Quantitative and Qualitative Disclosures about Market Risk

these transactions using a variety of scenarios, including natural gas 
prices remaining low for an extended period of time. As energy or 
environment attribute price volatility continues or as PPAs expire, the 
cash flows from certain of our projects are exposed to these market 
conditions and we work with the projects sponsors to minimize 
any impact as part of our on-going active asset management and 
portfolio monitoring. We often invest in utility scale solar projects 
by owning the land under the project where our rent is paid out of 
project operational costs before the debt or equity in the project 
receives any payments. Certain of the projects in which we invest 
may also be obligated to physically deliver energy under PPAs 
or related agreements, and to the extent they are unable to do so 
may be negatively impacted. Certain PPAs or related agreements 
may also price power at a different location than the location 
where power is delivered to the grid, and the projects may be 
negatively impacted to the extent to which these prices differ. To 
the extent transmission and distribution infrastructure in geographies 
in which we invest is not able to accommodate additional power, 
additional renewable penetration from other new projects in certain 
geographic areas could decrease the revenues of our projects.
Environmental Risks
Our business is impacted by the effects of climate change and 
various related regulatory responses. We discuss the risks and 
opportunities associated with the impacts of climate change 
in Item 7. Management’s Discussion and Analysis of Financial 
Condition and Results of Operations - Impact of climate change on 
our future operations. This discussion outlines potential qualitative 
impacts to our business, quantitative illustrations of sensitivity as 
well as our strategy and resilience to these risks and opportunities. 
Risk Management
Our ongoing active asset management and portfolio monitoring 
processes provide investment oversight and valuable insight into 
our origination, underwriting and structuring processes. These 
processes create value through active monitoring of the state of our 
markets, enforcement of existing contracts and asset management. 
As described above, we engage in a variety of interest rate 
management techniques that seek to mitigate the economic effect 
of interest rate changes on the values of, and returns on, some 
of our assets. We seek to manage credit risk using thorough due 
diligence and underwriting processes, strong structural protections 
in our agreements with customers and continual, active asset 
management and portfolio monitoring. Additionally, we have a 
Finance and Risk Committee of our Board which discusses and 
reviews policies and guidelines with respect to our risk assessment 
and risk management for various risks, including, but not limited 
to, our interest rate, counter party, credit, capital availability, 
refinancing risks, and cybersecurity. While we cannot fully protect 
our investments, we seek to mitigate these risks by using third party 
experts to conduct engineering and weather analysis and insurance 
reviews as appropriate. Weather related risks are at times managed 
in cooperation with our clients where they buy offsetting power 
positions to mitigate power market disruptions or operational 
impacts. Once a transaction has closed we continue to monitor the 
environmental risks to the Portfolio. We further discuss our strategy 
to managing these risks in Item 7. Management’s Discussion and 
Analysis of Financial Condition and Results of Operations - Impact 
of climate change on our future operations.

HA Sustainable Infrastructure Capital, Inc.
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets 
of HA Sustainable Infrastructure Capital, Inc. (the Company) 
as of December 31, 2024 and 2023, the related consolidated 
statements of operations, comprehensive income, stockholders’ 
equity and cash flows for each of the three years in the period ended 
December 31, 2024, and the related notes and financial statement 
schedule listed in the Index at Item 15(a)(2) (collectively referred 
to as the “consolidated financial statements”). In our opinion, the 
consolidated financial statements present fairly, in all material 
respects, the financial position of the Company at December 31, 
2024 and 2023, and the results of its operations and its cash flows 
for each of the three years in the period ended December 31, 2024, 
in conformity with U.S. generally accepted accounting principles.
We also have audited, in accordance with the standards of the 
Public Company Accounting Oversight Board (United States) 
(PCAOB), the Company’s internal control over financial reporting 
as of December 31, 2024, based on criteria established in 
Internal Control—Integrated Framework issued by the Committee 
of Sponsoring Organizations of the Treadway Commission 
(2013 framework), and our report dated February 14, 2025 
expressed an unqualified opinion thereon.
Basis for Opinion
These financial statements are the responsibility of the Company’s 
management. Our responsibility is to express an opinion on the 
Company’s financial statements based on our audits. We are a 
public accounting firm registered with the PCAOB and are required 
to be independent with respect to the Company in accordance 
with the U.S. federal securities laws and the applicable rules 
and regulations of the Securities and Exchange Commission and 
the PCAOB.
We conducted our audits in accordance with the standards of the 
PCAOB. Those standards require that we plan and perform the 
audit to obtain reasonable assurance about whether the financial 
statements are free of material misstatement, whether due to error or 
fraud. Our audits included performing procedures to assess the risks 
of material misstatement of the financial statements, whether due to 
error or fraud, and performing procedures that respond to those 
risks. Such procedures included examining, on a test basis, evidence 
regarding the amounts and disclosures in the financial statements. 
Our audits also included evaluating the accounting principles 
used and significant estimates made by management, as well as 
evaluating the overall presentation of the financial statements. We 
believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matter
The critical audit matter communicated below is a matter arising 
from the current period audit of the financial statements that was 
communicated or required to be communicated to the audit 
committee and that: (1) relates to accounts or disclosures that are 
material to the financial statements and (2) involved our especially 
challenging, subjective or complex judgments. The communication 
of the critical audit matter does not alter in any way our opinion on 
the consolidated financial statements, taken as a whole, and we are 
not, by communicating the critical audit matter below, providing a 
separate opinion on the critical audit matter or on the account or 
disclosure to which it relates.
59
HASI Form 10-K
Part II
Item 8. Financial Statements and Supplementary Data

Accounting for Equity Investments
Description of 
the Matter
As discussed in Note 2 to the consolidated financial statements, the Company makes investments that are accounted for 
under the equity method of accounting. As of December 31, 2024, the Company held $3.61 billion of equity investments. 
The Company’s determination that it does not have the power to direct the significant activities impacting each of the 
investees’ economic performance (“power”) is critical to its determination that it is not the primary beneficiary of the 
investee. Also, as described in Note 2 to the consolidated financial statements, for equity method investments that contain 
preferences with regard to cash flows from operations, capital events and liquidation in their respective limited liability 
company agreements (“LLC Agreements”), the Company applies the Hypothetical Liquidation at Book Value (“HLBV”) 
method to record its share of profits and losses on these investments, which is recorded one quarter in arrears to allow 
for receipt of financial information from its investees. Also, as described in Note 2, the Company evaluates their equity 
method investments quarterly for other than temporary impairment (“OTTI”). This requires evaluating available qualitative 
and quantitative evidence to determine whether there may be indicators of a loss in investment value below carrying value. 
Auditing the Company’s determination of whether it has power over an investee was complex and required significant 
judgment to determine both the activities of the investee that most significantly impact the investee’s economics, and 
the distribution of power among the members of the investee that ultimately determine the outcome of such activities. In 
addition, auditing the Company’s application of the HLBV method was challenging and inherently complex, because 
the application is based on its interpretations of the liquidation provisions outlined within investees’ LLC Agreements. 
Lastly, evaluating available qualitative and quantitative evidence was subjective and required judgment as to whether 
there were indicators of a loss in investment value below carrying value.
How We 
Addressed the 
Matter in Our 
Audit
We tested the Company’s controls that address the risks of material misstatement relating to: i) the determination of whether 
the Company has the power to direct the significant activities of the investees, ii) the recognition of its share of investees’ profits 
and losses through use of the HLBV method based on financial information reported to the Company from its investees, and 
iii) the review of available qualitative and quantitative evidence in determining whether there may be indicators of a loss in 
investment value below carrying value. For example, we tested the Company’s controls over management’s review of the 
variable interest model and determination of whether the Company has power. We also tested controls over management’s 
review of the HLBV method, including the application of any liquidation provisions and the financial information reported 
from their investees. Lastly, we tested controls over management’s review of available quantitative and qualitative evidence 
and whether there were indicators of a loss in investment value below carrying value.
To evaluate whether the Company has power over each investee, our audit procedures included, on a sample basis, reading 
LLC Agreements and evaluating management’s analysis of the significant activities of the investee and which parties can direct 
those significant activities. For example, as part of our evaluation, we considered the purpose and design of each investee 
and the legal rights of each of the involved parties, including the significance of the decisions that each party makes. We 
also tested the rights of each party included in management’s analysis by comparing such rights to the LLC Agreements. 
We tested the Company’s application of the HLBV method for a sample of investments. Our audit procedures included, 
among others, involving tax professionals to assist in evaluating the Company’s application of the liquidation provisions 
within the LLC Agreements. Specifically, we assessed the Company’s HLBV calculations by agreeing provisions of the 
calculations, such as the application of stated preferred returns and allocation of tax attributes, to the terms of the 
LLC Agreements for each of these investments. We also performed additional procedures on the Company’s HLBV 
calculations that included, but were not limited to, recalculating the stated preferred returns, recalculating allocations 
of tax attributes, comparing inputs included within the calculations to the information reported to the Company by its 
investee, and recalculating the Company’s share of profits and losses of the investee.
We reviewed the Company’s evaluation of available qualitative and quantitative evidence and whether there may be 
indicators of a loss in investment value below carrying value for a sample of investments. This included, among others, 
evaluating management’s identification of indicators that the Company’s investments may have experienced a loss of value 
below carrying value, agreeing certain qualitative and quantitative information used in the assessment to source documents, 
testing clerical accuracy of the analysis as applicable, and assessing any contradictory evidence that arose during our audit.

Report of Independent Registered Public Accounting Firm
To the Stockholders and the Board of Directors of 
HA Sustainable Infrastructure Capital, Inc.
Opinion on Internal Control Over Financial Reporting
We have audited HA Sustainable Infrastructure Capital, Inc.’s 
internal control over financial reporting as of December 31, 2024, 
based on criteria established in Internal Control—Integrated 
Framework issued by the Committee of Sponsoring Organizations 
of the Treadway Commission (2013 framework) (the COSO criteria). 
In our opinion, HA Sustainable Infrastructure Capital, Inc. (the 
Company) maintained, in all material respects, effective internal 
control over financial reporting as of December 31, 2024, based 
on the COSO criteria.
We also have audited, in accordance with the standards of the 
Public Company Accounting Oversight Board (United States) 
(PCAOB), the consolidated balance sheets of the Company as of 
December 31, 2024 and 2023, the related consolidated statements 
of operations, comprehensive income, stockholders’ equity and cash 
flows for each of the three years in the period ended December 31, 
2024, and the related notes and financial statement schedule listed 
in the Index at Item 15(a)(2) and our report dated February 14, 
2025 expressed an unqualified opinion thereon.
Basis for Opinion
The Company’s management is responsible for maintaining effective 
internal control over financial reporting and for its assessment of the 
effectiveness of internal control over financial reporting included in 
the accompanying Management’s Report on Internal Control Over 
Financial Reporting. Our responsibility is to express an opinion on 
the Company’s internal control over financial reporting based on our 
audit. We are a public accounting firm registered with the PCAOB 
and are required to be independent with respect to the Company in 
accordance with the U.S. federal securities laws and the applicable 
rules and regulations of the Securities and Exchange Commission 
and the PCAOB.
We conducted our audit in accordance with the standards of the 
PCAOB. Those standards require that we plan and perform the 
audit to obtain reasonable assurance about whether effective 
internal control over financial reporting was maintained in all 
material respects.
Our audit included obtaining an understanding of internal 
control over financial reporting, assessing the risk that a material 
weakness exists, testing and evaluating the design and operating 
effectiveness of internal control based on the assessed risk, and 
performing such other procedures as we considered necessary in 
the circumstances. We believe that our audit provides a reasonable 
basis for our opinion.
Definition and Limitations of Internal Control Over Financial Reporting
A company’s internal control over financial reporting is a process 
designed to provide reasonable assurance regarding the reliability 
of financial reporting and the preparation of financial statements 
for external purposes in accordance with generally accepted 
accounting principles. A company’s internal control over financial 
reporting includes those policies and procedures that (1) pertain to 
the maintenance of records that, in reasonable detail, accurately 
and fairly reflect the transactions and dispositions of the assets of the 
company; (2) provide reasonable assurance that transactions are 
recorded as necessary to permit preparation of financial statements 
in accordance with generally accepted accounting principles, and 
that receipts and expenditures of the company are being made only 
in accordance with authorizations of management and directors 
of the company; and (3) provide reasonable assurance regarding 
prevention or timely detection of unauthorized acquisition, use, or 
disposition of the company’s assets that could have a material effect 
on the financial statements.
Because of its inherent limitations, internal control over financial 
reporting may not prevent or detect misstatements. Also, projections 
of any evaluation of effectiveness to future periods are subject to 
the risk that controls may become inadequate because of changes 
in conditions, or that the degree of compliance with the policies or 
procedures may deteriorate.

HA Sustainable Infrastructure Capital, Inc.
Notes to Consolidated Financial Statements
December 31, 2024
1.
The Company
HA Sustainable Infrastructure Capital, Inc., formerly known as Hannon 
Armstrong Sustainable Infrastructure Capital, Inc. prior to July 2, 2024 
(the “Company”), actively partners with clients to deploy real assets 
that facilitate the energy transition. Our investments take various forms, 
including equity, joint ventures, land ownership, lending and other 
financing transactions. We generate net investment income from our 
portfolio, and fees through gain-on sale securitization transactions, 
asset management and servicing, broker/dealer and other services. 
We also generate recurring income through our residual ownership 
in securitization and syndication structures.
The Company and its subsidiaries are hereafter referred to as “we,” 
“us” or “our.” We refer to the income producing assets that we hold 
on our balance sheet as our “Portfolio.” Our Portfolio includes:
• equity investments in either preferred or common structures in 
unconsolidated entities;
• receivables; and
• debt securities.
We finance our business through cash on hand, recourse and 
non-recourse debt, convertible securities, or equity issuances and 
may also decide to finance such transactions through the use of 
off-balance sheet securitization or syndication structures.
Our common stock is listed on the New York Stock Exchange 
(“NYSE”) under the symbol “HASI.” We intend to continue 
to operate our business in a manner that will maintain our 
exemption from registration as an investment company under the 
Investment Company Act of 1940 (the “1940 Act”), as amended. 
We operate our business through, and along with two of our 
wholly owned subsidiaries serve as the general partners of, our 
operating partnership subsidiary, Hannon Armstrong Sustainable 
Infrastructure, L.P., (the “Operating Partnership”), which was formed 
to acquire and directly or indirectly own our assets.
Transition to Taxable C Corporation
As a result of expanding opportunities in non-qualifying assets, 
effective January 1, 2024, we have revoked our real estate investment 
trust (“REIT”) election and are taxed as a C Corporation beginning 
in tax year 2024. Commencing with the taxable year ended 
December 31, 2024, all of the Company’s taxable income is subject 
to U.S. federal and state income tax at the applicable corporate tax 
rate. Dividends paid to stockholders are no longer tax deductible to 
us. The Company is also no longer subject to the REIT requirement for 
distributions to stockholders when the Company has taxable income.
The Company anticipates that operating as a taxable C Corporation 
will provide the Company with flexibility to execute various strategic 
initiatives without the constraints of complying with REIT requirements, 
including investing in power generating, transportation, and 
alternative fuel assets which are not REIT qualifying assets. The 
Company’s transition to a taxable C Corporation is not expected 
to result in significant incremental current income tax expense in 
the near term due to the availability of net operating loss (“NOL”) 
carryforwards and tax credits typically offered by the assets in which 
we often invest. See Note 10 for additional information.

Summary of Significant Accounting Policies
Basis of Presentation
The preparation of financial statements in accordance with U.S. 
generally accepted accounting principles (“GAAP”) requires 
management to make estimates and assumptions that affect the 
reported amounts of assets and liabilities and the reported amounts 
of revenues and expenses during the reporting period. Actual results 
could differ from these estimates and such differences could be 
material. In the opinion of management, all adjustments necessary 
to present fairly our financial position, results of operations and 
cash flows have been included. Certain amounts in the prior years 
have been reclassified to conform to the current year presentation.
The consolidated financial statements include our accounts and 
controlled subsidiaries, including the Operating Partnership. All 
material intercompany transactions and balances have been 
eliminated in consolidation.
Following the guidance for non-controlling interests in Financial 
Accounting Standards Board Accounting Standards Codification 
(“ASC”) 810, Consolidation (“ASC 810”), references in this report 
to our earnings per share and our net income and stockholders’ 
equity attributable to common stockholders do not include amounts 
attributable to non-controlling interests.

Part II
Item 8. Financial Statements and Supplementary Data

Consolidation
We account for our investments in entities that are considered voting 
interest entities or variable interest entities (“VIEs”) under ASC 810 
and assess on an ongoing basis whether we should consolidate 
these entities. We have established various special purpose entities 
or securitization trusts for the purpose of securitizing certain assets 
that are not consolidated in our financial statements as described 
below in Securitization of Financial Assets.
Since we have assessed that we have power over and receive 
the benefits from those special purpose entities that are formed for 
the purpose of holding our assets on our balance sheet, we have 
concluded we are the primary beneficiary and should consolidate 
these entities under the provisions of ASC 810. We also have certain 
subsidiaries we deem to be voting interest entities that we control 
through our ownership of voting interests and accordingly consolidate.
Certain of our equity method investments were determined to be 
interests in VIEs in which we are not the primary beneficiary, as 
we do not direct the significant activities of these entities, and thus 
we account for those investments as Equity Method Investments 
as discussed below. Our maximum exposure to loss through these 
investments is typically limited to their recorded values. However, 
we may provide financial commitments to these VIEs or guarantee 
certain of their obligations. Certain other entities in which we have 
equity investments have been assessed to be voting interest entities 
and as we exert significant influence rather than control through our 
ownership of voting interests, we do not consolidate them and thus 
account for them as equity method investments described below.

We have made equity investments, typically in structures where we 
have a preferred return position. These investments are typically 
owned in holding companies (using limited liability companies 
(“LLCs”) taxed as partnerships) where we partner with either the 
operator of the project or other institutional investors. We share in 
the cash flows, income, and tax attributes according to a negotiated 
schedule which typically does not correspond with our ownership 
percentages. Investors in a preferred return position, if any, typically 
receive a priority distribution of all or a portion of the project’s cash 
flows, and in some cases, tax attributes. Once the preferred return, if 
applicable, is achieved, the partnership “flips” and common equity 
investors, often the operator of the project, receive a larger portion 
of the cash flows, with the previously preferred investors retaining 
an on-going residual interest.
Our equity investments in climate solutions projects are accounted for 
under the equity method of accounting. Under the equity method of 
accounting, the carrying value of these equity method investments is 
determined based on amounts we invested, adjusted for earnings or 
losses of the investee allocated to us based on the LLC agreement, 
less distributions received. We generally conclude that investments 
where the LLC agreements contain preferences with regard to cash 
flows from operations, capital events or liquidation are considered 
substantive profit sharing arrangements, so we accordingly reflect 
our share of profits and losses by determining the difference between 
our claim on the investee’s reported book value at the beginning and 
the end of the period, which is adjusted for distributions received 
and contributions made during the period. This claim is calculated 
as the amount we would receive if the investee were to liquidate all 
of its assets at the recorded amounts determined in accordance with 
GAAP and distribute the resulting cash to creditors and investors in 
accordance with their respective priorities. This method is referred to 
as the hypothetical liquidation at book value method (“HLBV”). Our 
exposure to loss in these investments is limited to the amount of our 
equity investment, as well as receivables from or guarantees made 
to the same investee.
Any difference between the amount of our investment and the amount 
of underlying equity in net assets at the time of our investment is 
generally amortized over the life of the assets and liabilities to which 
the difference relates. Cash distributions received from each equity 
method investment are classified as operating activities to the extent of 
cumulative earnings for each investment in our consolidated statements 
of cash flows. Our initial investment and additional cash distributions 
beyond the amounts that are classified as operating activities are 
classified as investing activities in our consolidated statements of cash 
flows. We typically recognize earnings one quarter in arrears for 
these investments to allow for the receipt of financial information. 
Our proportionate share of any revenue earned from equity method 
investees is eliminated through the income (loss) from equity method 
investment line of our income statement.
We evaluate quarterly whether the current carrying value of our 
investments accounted for using the equity method have an other 
than temporary impairment (“OTTI”). An OTTI occurs when the 
estimated fair value of an investment is below the carrying value 
and the difference is determined to not be recoverable in the near 
term. First, we consider both qualitative and quantitative evidence 
in determining whether there is an indicator of a loss in investment 
value below carrying value. After considering the weight of available 
evidence, if it is determined that there is an indication of loss in 
investment value, we will perform a fair value analysis. If the resulting 
fair value is less than the carrying value, we will determine if this 
loss in value is OTTI, and we will recognize any OTTI in the income 
statement as an impairment. This evaluation requires significant 
judgment regarding, but not limited to, the severity and duration 
of the impairment; the ability and intent to hold the securities until 
recovery; financial condition, liquidity, and near-term prospects of 
the issuer; specific events; and other factors.
Receivables
Receivables include project loans and receivables. Unless 
otherwise noted, we generally have the ability and intent to hold 
our receivables for the foreseeable future and accordingly we 
classify them as held for investment. Our ability and intent to hold 
certain receivables may change from time to time depending on a 
number of factors including economic, liquidity and capital market 
conditions. At inception of the arrangement, the carrying value of 
receivables held for investment represents the present value of the 
note, lease or other payments, net of any unearned fee income, 
69
HASI Form 10-K
Part II
Item 8. Financial Statements and Supplementary Data

which is recognized as income over the term of the note or lease 
using the effective interest method. Receivables that are held for 
investment are carried at amortized cost, net of any unamortized 
acquisition premiums or discounts and include origination and 
acquisition costs, as applicable. Our initial investment and principal 
repayments of these receivables are classified as investing activities 
and the interest collected is classified as operating activities in our 
consolidated statements of cash flows. Receivables that we intend to 
sell in the short-term are classified as held-for-sale and are carried 
at the lower of amortized cost or fair value on our balance sheet, 
which is assessed on an individual asset basis. The purchases and 
proceeds from receivables that we intend to sell at origination are 
classified as operating activities in our consolidated statements of 
cash flows. Interest collected is classified as an operating activity in 
our consolidated statements of cash flows. Receivables from certain 
projects are subordinate to preferred investors in a project who are 
allocated the majority of such project’s cash in the early years of the 
investment. Accordingly, such receivables may include the ability to 
defer scheduled interest payments in exchange for increasing our 
receivable balance. We generally accrue this paid-in-kind (“PIK”) 
interest when collection is expected and cease accruing PIK interest 
if there is insufficient value to support the accrual or we expect 
that any portion of the principal or interest due is not collectible. 
The change in PIK in any period is included in Change in accrued 
interest on receivables and investments in the operating section of 
our statement of cash flows.
We evaluate our receivables for an allowance as determined 
under ASC Topic 326 Financial Instruments- Credit Losses (“Topic 
326”) and for our internally derived asset performance categories 
included in Note 6 to our financial statements on at least a quarterly 
basis and more frequently when economic or other conditions 
warrant such an evaluation. When a receivable becomes 90 days 
or more past due, and if we otherwise do not expect the debtor 
to be able to service all of its debt or other obligations, we will 
generally consider the receivable delinquent or impaired and place 
the receivable on non-accrual status and cease recognizing income 
from that receivable until the borrower has demonstrated the ability 
and intent to pay contractual amounts due. If a receivable’s status 
significantly improves regarding the debtor’s ability to service the 
debt or other obligations, we will remove it from non-accrual status.
We determine our allowance based on the current expectation of 
credit losses over the contractual life of our receivables as required 
by Topic 326. We use a variety of methods in developing our 
allowance including discounted cash flow analysis and probability-
of-default/loss given default (“PD/LGD”) methods. In developing 
our estimates, we consider our historical experience with our and 
similar assets in addition to our view of both current conditions 
and what we expect to occur within a period of time for which 
we can develop reasonable and supportable forecasts, typically 
two years. For periods following the reasonable and supportable 
forecast period, we revert to historical information when developing 
assumptions used in our estimates. In developing our forecasts, 
we consider a number of qualitative and quantitative factors in 
our assessment, which may include a project’s operating results, 
loan-to-value ratio, any cash reserves held by the project, the ability 
of expected cash from operations to cover the cash flow requirements 
currently and into the future, key terms of the transaction, the ability 
of the borrower to refinance the transaction, other credit support 
from the sponsor or guarantor and the project’s collateral value. 
In addition, we consider the overall economic environment, the 
climate solutions sector, the effect of local, industry, and broader 
economic factors such as unemployment rates and power prices, 
the impact of any variation in weather and the historical and 
anticipated trends in interest rates, defaults and loss severities for 
similar transactions. For assets where the obligor is a publicly rated 
entity, we consider the published historical performance of entities 
with similar ratings in developing our estimate of an allowance, 
making adjustments determined by management to be appropriate 
during the reasonable and supportable forecast period.
We have made certain loan commitments that are within the 
scope of Topic 326. When estimating an allowance for these loan 
commitments we consider the probability of certain amounts to 
be funded and apply either a discounted cash flow or PD/LGD 
methodology as described above. We charge off receivables 
against the allowance, if any, when we determine the unpaid 
principal balance is uncollectible, net of recovered amounts. For 
those assets where we record our allowance using a discounted cash 
flow method, we have elected to record the change in allowance 
due solely to the passage of time through the provision for loss on 
receivables in our income statement. Any provision we record for 
an allowance is a non-cash reconciling item to cash from operating 
activities in our consolidated statements of cash flows.
Real Estate
Real estate consists of land or other real property and its related lease 
intangibles, net of any amortization. Our real estate is generally 
leased to tenants on a triple net lease basis, whereby the tenant 
is responsible for all operating expenses relating to the property, 
generally including property taxes, insurance, maintenance, repairs 
and capital expenditures. Certain real estate transactions may be 
characterized as “failed sale-leaseback” transactions as defined 
under ASC Topic 842, Leases, and thus are accounted for as 
financing transactions similarly to our commercial receivables as 
described above in Government and Commercial Receivables.
For our real estate lease transactions that are classified as operating 
leases, the scheduled rental revenue typically varies during the 
lease term and thus rental income is recognized on a straight-line 
basis, unless there is considerable risk as to collectability, so as to 
produce a constant periodic rent over the term of the lease. Accrued 
rental income is the aggregate difference between the scheduled 
rents that vary during the lease term and the income recognized 
on a straight-line basis and is recorded in other assets. Expenses, 
if any, related to the ongoing operation of leases where we are the 
lessor are charged to operations as incurred. Our initial investment 
is classified as investing activities and income collected for rental 
income is classified as operating activities in our consolidated 
statements of cash flows.
70
HASI Form 10-K
Part II
Item 8. Financial Statements and Supplementary Data

When our real estate transactions are treated as an asset acquisition 
with an operating lease, we typically record our real estate 
purchases at cost, including acquisition and closing costs, which 
is allocated to each tangible and intangible asset acquired on a 
relative fair value basis.
Securitization of Assets
We have established various special purpose entities or 
securitization trusts for the purpose of securitizing certain financial 
assets. We determined that the trusts used in securitizations are 
VIEs, as defined in ASC 810. When we conclude that we are not 
the primary beneficiary of certain trusts because we do not have 
power over those trusts’ significant activities, we do not consolidate 
the trust. We typically serve as primary or master servicer of these 
trusts; however, as the servicer, we do not have the power to make 
significant decisions impacting the performance of the trusts.
We account for transfers of financial assets to these securitization 
trusts as sales pursuant to ASC 860, Transfers and Servicing
(“ASC 860”), when we have concluded the transferred assets have 
been isolated from the transferor (i.e., put presumptively beyond 
the reach of the transferor and its creditors, even in bankruptcy 
or other receivership) and we have surrendered control over the 
transferred assets. When we are unable to conclude that we have 
been sufficiently isolated from the securitized financial assets, we 
treat such trusts as secured borrowings, retaining the assets on our 
balance sheet and recording the amounts due to the trust investor as 
non-recourse debt. Transfers of non-financial assets are accounted 
for under ASC 610-20, Gains and Losses from the Derecognition 
of Non-financial Assets, and those transfers are accounted for as 
sales when we have concluded that we have transferred control of 
the non-financial asset.
For transfers treated as sales under ASC 860, we have received 
true-sale-at-law and non-consolidation legal opinions to support 
our conclusion regarding the transferred financial assets. When we 
sell financial assets in securitizations, we generally retain interests in 
the form of servicing rights and residual assets, which we refer to as 
securitization assets. 
Gain or loss on the sale of assets is calculated based on the excess of 
the proceeds received from the securitization (net of any transaction 
costs) plus any retained interests obtained over the cost basis of the 
assets sold. For retained interests, we generally estimate fair value 
based on the present value of future expected cash flows using 
our best estimates of the key assumptions of anticipated losses, 
prepayment rates, and current market discount rates commensurate 
with the risks involved. Cash flows related to our securitizations at 
origination are classified as operating activities in our consolidated 
statements of cash flows. 
We initially account for all separately recognized servicing assets 
and servicing liabilities at fair value and subsequently measure 
such servicing assets and liabilities using the amortization method. 
Servicing assets and liabilities are amortized in proportion to, and 
over the period of, estimated net servicing income with servicing 
income recognized as earned. We assess servicing assets for 
impairment at each reporting date. If the amortized cost of servicing 
assets is greater than the estimated fair value, we will recognize an 
impairment in net income. 
We account for our other retained interests in securitized financial 
assets, the residual assets, similar to available-for-sale debt securities 
and carry them at fair value with changes in fair value recorded in 
accumulated other comprehensive income (“AOCI”) pursuant to 
ASC 325-40, Beneficial Interests in Securitized Financial Assets. 
Income related to the residual assets is recognized using the effective 
interest rate method and included in securitization income in our 
income statement. Our residual assets are evaluated for impairment 
on a quarterly basis under Topic 326. A residual asset is impaired 
if its fair value is less than its carrying value. The credit component 
of impairments, if any, are recognized by recording an allowance 
against the amortized cost of the asset. For changes in expected cash 
flows, we will calculate a new yield based on the current amortized 
cost of the residual assets and the revised expected cash flows. 
This yield is used prospectively to recognize our income related to 
these assets. Residual interests in securitized non-financial assets are 
accounted for as equity method investments, and subject to those 
accounting policies described above.
Cash and Cash Equivalents
Cash and cash equivalents include short-term government 
securities, certificates of deposit and money market funds, all of 
which had an original maturity of three months or less at the date 
of purchase. These securities are carried at their purchase price, 
which approximates fair value.
Restricted Cash
Restricted cash includes cash and cash equivalents set aside with 
certain lenders primarily to support obligations outstanding as of 
the balance sheet dates. Restricted cash is reported as part of other 
assets in our consolidated balance sheets. Refer to Note 3 to our 
financial statements in this Form 10-K for disclosure of the balances 
of restricted cash included in other assets.
Convertible Notes
We have issued convertible and exchangeable senior unsecured 
notes (together, “Convertible Notes”) that are accounted for in 
accordance with ASC 470-20, Debt with Conversion and Other 
Options, and ASC 815, Derivatives and Hedging (“ASC 815”). 
Under ASC 815, issuers of certain convertible or exchangeable 
debt instruments are generally required to separately account for 
the conversion or exchange option of the debt instrument as either 
a derivative or equity, unless it meets the scope exemption for 
contracts indexed to, and settled in, an issuer’s own equity. Since 
our conversion or exchange options are both indexed to our equity 
and can be settled in our common stock at our option, we have 
met the scope exemption, and therefore, we do not separately 
account for the embedded conversion or exchange options. 
The initial issuance and any principal repayments are classified 
as financing activities and interest payments are classified as 
71
HASI Form 10-K
Part II
Item 8. Financial Statements and Supplementary Data

operating activities in our consolidated statements of cash flows. 
If converted or exchanged, the carrying value of each Convertible 
Note is reclassified into stockholders’ equity.
Derivative Financial Instruments
We use derivative financial instruments, including interest rate swaps 
and collars, to manage, or hedge, our interest rate risk exposures 
associated with new debt issuances and anticipated refinancings 
of existing debt, to manage our exposure to fluctuations in interest 
rates on floating-rate debt, and to optimize the mix of our fixed and 
floating-rate debt. Our objective is to reduce the impact of changes 
in interest rates on our results of operations and cash flows. The fair 
values of our interest rate derivatives designated and qualifying as 
effective cash flow hedges are reflected in our consolidated balance 
sheets as a component of other assets (if in an unrealized asset 
position) or accounts payable, accrued expenses and other (if in an 
unrealized liability position) and in net unrealized gains and losses 
in AOCI as described below. The cash settlements of our interest rate 
swaps, if any, are classified as operating activities in our consolidated 
statements of cash flows.
The interest rate derivatives we use are intended to be designated 
as cash flow hedges and are considered highly effective in reducing 
our exposure to the interest rate risk that they are designated to 
hedge. This effectiveness is required in order to qualify for hedge 
accounting. Instruments that meet the required hedging criteria 
are formally designated as hedging instruments at the inception of 
the derivative contract. Derivatives are recorded at fair value. If a 
derivative is designated as a cash flow hedge and meets the highly 
effective threshold, the change in the fair value of the derivative is 
recorded in AOCI, net of associated deferred income tax effects. Any 
amounts in AOCI are recognized in earnings along with the income 
tax effect at the same time as the hedged item, which is when interest 
expense is recognized. For any derivative instruments not designated 
as hedging instruments, changes in fair value would be recognized 
in earnings in the period that the change occurs. We assess, both 
at the inception of the hedge and on an ongoing basis, whether the 
derivatives designated as cash flow hedges are highly effective in 
offsetting the changes in cash flows of the hedged items. We also 
assess on an ongoing basis whether the forecasted transactions 
remain probable, and discontinue hedge accounting if we conclude 
that they do not. We do not hold derivatives for trading purposes. 
Any collateral posted or received as credit support against derivative 
positions are netted against those derivatives in our balance sheets. 
When our collateral account with any particular counterparty is in 
a liability position, we include inflows and outflows related to those 
collateral postings within financing activities in our statement of cash 
flows. When our collateral account with any particular counterparty is 
in an asset position, we include inflows and outflows related to those 
collateral postings within investing activities in our statement of cash 
flows. The inflows and outflows related to instruments designated as 
cash flow hedges are included within our statement of cash flows 
in the same section as the hedge item, which is typically operating 
activities for our instruments which hedge interest rate risk exposures.
Interest rate derivative contracts contain a credit risk that 
counterparties may be unable to fulfill the terms of the agreement. 
We attempt to minimize that risk by evaluating the creditworthiness 
of our counterparties, who are limited to major banks and 
financial institutions, and do not anticipate nonperformance by the 
counterparties due to their requirement to post collateral.
We have entered into certain capped call transactions to mitigate the 
economic dilution that may result from the conversion or exchange of 
certain of our Convertible Notes. These transactions are freestanding 
equity-linked derivative instruments that qualify for the exemption 
for contracts indexed to, and settled in, an issuer’s own equity found 
in ASC 815, and accordingly the payment of the option premium 
was recorded as a reduction of Additional Paid-in-Capital within 
our Statement of Stockholders’ Equity.
Income Taxes
We elected and qualified to be taxed as a REIT for U.S. federal income 
tax purposes, commencing with our taxable year ended December 31, 
2013 through our taxable year ended December 31, 2023. We have 
revoked our REIT election effective January 1, 2024, and beginning 
in taxable year 2024 are taxed as a taxable C Corporation. For 
tax years 2023 and prior, we had taxable REIT subsidiaries (“TRS”) 
that were taxed separately, and that were generally subject to U.S. 
federal, state, and local income taxes. To qualify as a REIT, we were 
required to meet on an ongoing basis several organizational and 
operational requirements, including a requirement that we distribute 
at least 90% of our REIT’s net taxable income before dividends paid, 
excluding capital gains, to our stockholders each year. As a REIT, 
for tax years ended December 31, 2023 and earlier, we were not 
subject to U.S. federal corporate income tax on that portion of net 
income that was distributed to our owners in accordance with the 
REIT rules. Subsequent to our REIT status revocation, all of our net 
taxable income is subject to U.S. federal and state income tax at the 
applicable corporate tax rate, and dividends paid to stockholders 
are no longer tax deductible. 
We account for income taxes under ASC 740, Income Taxes
(“ASC 740”) using the asset and liability method. Deferred tax 
assets and liabilities are recognized for the estimated future 
tax consequences attributable to the differences between the 
consolidated financial statement carrying amounts of existing assets 
and liabilities and their respective tax bases. Deferred tax assets and 
liabilities are measured using enacted tax rates in effect for the year 
in which those temporary differences are expected to be recovered 
or settled. The effect on deferred tax assets and liabilities from a 
change in tax rates is recognized in earnings in the period when 
the new rate is enacted. We evaluate any deferred tax assets for 
valuation allowances based on an assessment of available evidence 
including sources of taxable income, prior years taxable income, 
any existing taxable temporary differences and our future investment 
and business plans that may give rise to taxable income. We treat 
any tax credits we receive from our equity investments in renewable 
energy projects as reductions of federal income taxes of the year in 
which the credit arises.
72
HASI Form 10-K
Part II
Item 8. Financial Statements and Supplementary Data

We apply ASC 740 with respect to how uncertain tax positions 
should be recognized, measured, presented, and disclosed in the 
financial statements. This guidance requires the accounting and 
disclosure of tax positions taken or expected to be taken in the 
course of preparing our tax returns to determine whether the tax 
positions are “more likely than not” to be sustained by the applicable 
tax authority. We are required to analyze all open tax years, as 
defined by the statute of limitations, for all major jurisdictions, which 
includes U.S. federal and certain states.
Equity-Based Compensation
We have adopted equity incentive plans which provide for grants of 
stock options, stock appreciation rights, restricted stock units, shares 
of restricted common stock, phantom shares, dividend equivalent 
rights, long-term incentive-plan units (“LTIP Units”) and other restricted 
limited partnership units issued by our Operating Partnership and 
other equity-based awards. From time to time, we may grant equity or 
equity-based awards as compensation to our independent directors, 
employees, advisors, consultants and other personnel. Certain 
awards earned under each plan are based on achieving various 
performance or market targets, which are generally earned between 
0% and 200% of the initial target, depending on the extent to which 
the performance or market target is met. In addition to performance 
or market targets, income or gain must be allocated by our Operating 
Partnership to certain LTIP Units issued by our Operating Partnership 
so that the capital accounts of such units are equalized with the capital 
accounts of other holders of OP units before parity is reached and 
LTIP Units can be converted to limited partnership units.
We record compensation expense for grants made in accordance 
with ASC 718, Compensation—Stock Compensation. We record 
compensation expense for unvested grants that vest solely based on 
service conditions on a straight-line basis over the vesting period of 
the entire award based upon the fair market value of the grant on the 
date of grant. Fair market value for restricted common stock is based 
on our share price on the date of grant. For awards where the vesting 
is contingent upon achievement of certain performance targets, 
compensation expense is measured based on the fair market value 
on the grant date and is recorded over the requisite service period 
(which includes the performance period). Actual performance results 
at the end of the performance period determines the number of 
shares that will ultimately be awarded. We have also issued awards 
where the vesting is contingent upon service being provided for a 
defined period and certain market conditions being met. The fair 
value of these awards, as measured at the grant date, is recognized 
over the requisite service period, even if the market conditions are 
not met. The grant date fair value of these awards was developed 
by an independent appraiser using a Monte Carlo simulation. 
Forfeitures of unvested awards are recognized as they occur.
We have a retirement policy that provides for full vesting at retirement 
of any time-based awards that were granted prior to the date of 
retirement and permits the vesting of performance-based awards 
that were granted prior to the date of retirement according to the 
original vesting schedule of the award, subject to the achievement of 
the applicable performance measures and without the requirement 
for continued employment. Employees are eligible for the retirement 
policy upon meeting age and years of service criteria. We record 
compensation expense for unvested grants through the date in which 
an employee meets the retirement criteria.
Earnings Per Share
We compute earnings per share of common stock in accordance 
with ASC 260, Earnings Per Share. Basic earnings per share is 
calculated by dividing net income attributable to controlling 
stockholders (after consideration of the earnings allocated to 
unvested grants, if applicable) by the weighted-average number 
of shares of common stock outstanding during the period excluding 
the weighted average number of unvested grants, if applicable 
(“participating securities” as defined in Note 12 to our financial 
statements in this Form 10-K). Diluted earnings per share is 
calculated by dividing net income attributable to controlling 
stockholders (after consideration of the earnings allocated to 
unvested grants, if applicable) by the weighted-average number 
of shares of common stock outstanding during the period plus 
other potential common stock instruments if they are dilutive. Other 
potentially dilutive common stock instruments include our unvested 
restricted stock, other equity-based awards, and Convertible Notes. 
The restricted stock and other equity-based awards are included if 
they are dilutive using the treasury stock method. The treasury stock 
method assumes that theoretical proceeds received for future service 
provided is used to purchase shares of treasury stock at the average 
market price per share of common stock, which is deducted from the 
total shares of potential common stock included in the calculation. 
When unvested grants are dilutive, the earnings allocated to these 
dilutive unvested grants are not deducted from the net income 
attributable to controlling stockholders when calculating diluted 
earnings per share. The Convertible Notes are included if they 
are dilutive using the if-converted method, which removes interest 
expense related to the Convertible Notes from the net income 
attributable to controlling stockholders and includes the weighted 
average shares of potential common stock over the period issuable 
upon conversion or exchange of the note. No adjustment is made 
for shares of potential common stock that are anti-dilutive during a 
period. Our capped call transactions are anti-dilutive and therefore 
their impact will be excluded from earnings per share.
Segment Reporting
We manage our business as a single portfolio which we originate from 
a single pipeline, and accordingly we report all of our activities as 
one reportable segment. Our single reportable segment generates net 
investment and equity method investment income through investments 
in climate solutions projects, as well as revenue through the gain on 
sale of assets and recurring asset management fees. The consolidated 
financial statements presented herein reflect the activities of our 
single reportable segment, and the accounting policies of our single 
reportable segment are those found here in this Note 2. Our chief 
operating decision maker (“CODM”) is our chief executive officer.
73
HASI Form 10-K
Part II
Item 8. Financial Statements and Supplementary Data

The CODM assesses performance for this segment and decides how 
to allocate resources based in part on net income as recorded in our 
income statement. Included in this metric are the significant segment 
expenses reviewed by the CODM, which include interest expense, 
compensation and benefits, and general and administrative, each of 
which is reported in our income statement. We do not have material 
intra-company sales or transfers.
In evaluating segment assets, the CODM uses receivables, equity 
method investments, real estate, and investments as reported on our 
balance sheet, which together we refer to as our Portfolio. Amounts 
invested in such assets can be found in our statement of cash flows. 
Segment asset amounts are used by the CODM when evaluating 
the return on investment on our Portfolio.
Recently Issued Accounting Pronouncements
Accounting standards updates issued before February 14, 2025, 
and effective after December 31, 2024, are not expected to have a 
material effect on our consolidated financial statements and related 
disclosures. There were no accounting standards that became effective 
in the year ended December 31, 2024 that had a material effect on 
our consolidated financial statements and related disclosures.
3.
Fair Value Measurements
Fair value is defined as the price that would be received for an asset 
or paid to transfer a liability in an orderly transaction between market 
participants on the measurement date. The fair value accounting 
guidance provides a three-level hierarchy for classifying financial 
instruments. The levels of inputs used to determine the fair value of 
our financial assets and liabilities carried on the balance sheet at fair 
value and for those which only disclosure of fair value is required 
are characterized in accordance with the fair value hierarchy 
established by ASC 820, Fair Value Measurements. Where inputs 
for a financial asset or liability fall in more than one level in the 
fair value hierarchy, the financial asset or liability is classified in 
its entirety based on the lowest level input that is significant to the 
fair value measurement of that financial asset or liability. We use 
our judgment and consider factors specific to the financial assets 
and liabilities in determining the significance of an input to the fair 
value measurements. As of December 31, 2024 and December 31, 
2023, only our residual assets related to our securitization trusts, our 
derivatives, and our investments were carried at fair value on the 
consolidated balance sheets on a recurring basis. The three levels 
of the fair value hierarchy are described below:
• Level 1—Quoted prices (unadjusted) in active markets that are 
accessible at the measurement date.
• Level 2—Observable prices that are based on inputs not quoted 
on active markets, but corroborated by market data.
• Level 3—Unobservable inputs are used when little or no market 
data is available.
The tables below state the estimated fair value of our financial 
instruments on our balance sheet. Unless otherwise discussed below, 
fair values for our Level 2 and Level 3 measurements are measured 
using a discounted cash flow model, contractual terms and inputs 
which consist of base interest rates and spreads over base rates 
which are based upon market observation and recent comparable 
transactions. An increase in these inputs would result in a lower fair 
value and a decline would result in a higher fair value. Our Senior 
Unsecured Notes (as defined below) and Convertible Notes are 
valued using a market based approach and observable prices. The 
receivables held-for-sale, if any, are carried at the lower of cost or

Other than as discussed in Note 5, loss positions are due to interest rates movements and is not indicative of credit deterioration. We have the intent and ability to hold these investments until 
a recovery of fair value.
In determining the fair value of our securitization residual assets, as 
of December 31, 2024 and 2023, we used a market-based risk-free 
rate and added a range of interest rate spreads of approximately 
1% to 6% based upon transactions involving similar assets. The 
weighted average discount rate used to determine the fair value 
of our securitization residual assets as of December 31, 2024 and 
2023 was 7.3% and 6.6%, respectively.
Non-recurring Fair Value Measurements
Our financial statements may include non-recurring fair value 
measurements related to acquisitions and non-monetary transactions, 
if any. Assets acquired in a business combination, if any, are recorded 
at their fair value. We may use third party valuation firms to assist us 
with developing our estimates of fair value.
Concentration of Credit Risk
Receivables, real estate leases, and debt investments consist 
primarily of receivables from various projects, U.S. federal 
government-backed receivables, and investment grade state and 
local government receivables and do not, in our view, represent 
a significant concentration of credit risk given the large number of 
diverse offtakers and other obligors of the projects. Additionally, 
certain of our investments are collateralized by projects concentrated 
in certain geographic regions throughout the United States. These 
investments typically have structural credit protections to mitigate 
our risk exposure and, in most cases, the projects are insured for 
estimated physical loss which helps to mitigate the possible risk from 
these concentrations.

Non-Controlling Interest
Units of limited partnership interests in the Operating Partnership 
(“OP units”) that are owned by limited partners other than us are 
included in non-controlling interest on our consolidated balance 
sheets. The non-controlling interest holders are generally allocated 
their pro rata share of income, other comprehensive income and 
equity transactions.
The outstanding OP units not held by us represent approximately 
1% of our outstanding OP units and are redeemable by the limited 
partners for cash, or at our option, for a like number of shares of our 
common stock. Non-controlling interest holders redeemed 10,000 
OP units during the year ended December 31, 2024, and no OP 
units were exchanged during the year ended December 31, 2023. 
We have also granted to members of our leadership team and 
directors LTIP Units pursuant to our equity incentive plans. The 
LTIP Units issued to employees are held by HASI Management 
HoldCo LLC. The LTIP Units are designed to qualify as profits interests 
in the Operating Partnership and initially will have a capital account 
balance of zero and, therefore, will not have full parity with OP units 
with respect to liquidating distributions or other rights. However, 
the amended and restated agreement of limited partnership of the 
Operating Partnership (the “OP Agreement”) provides that “book 
gains,” or economic appreciation, in the Operating Partnership 
will be allocated first to the LTIP Units until the capital account per 
LTIP Units is equal to the capital account per-unit of the OP units. 
Under the terms of the OP Agreement, the Operating Partnership will 
revalue its assets upon the occurrence of certain specified events, 
and any increase in valuation from the time of grant until such event 
will be allocated first to the holders of LTIP Units to equalize the 
capital accounts of such holders with the capital accounts of OP 
unit holders. Once this has occurred, the LTIP Units will achieve full 
parity with the OP units for all purposes, including with respect to 
liquidating distributions and redemption rights. In addition to these 
attributes, there are vesting and settlement conditions similar to our 
other equity-based awards as discussed in Notes 2 and 11 to our 
financial statements in this Form 10-K.

In connection with securitization transactions, we typically retain 
servicing responsibilities and residual assets. We generally 
receive annual servicing fees that are typically up to 0.25% of the 
outstanding balance. We may periodically make servicer advances, 
that are subject to credit risk. Included in securitization assets in our 
consolidated balance sheets are our servicing assets at amortized 
cost and our residual assets at fair value. Our residual assets are 
subordinate to investors’ interests, and their values are subject to 
credit, prepayment and interest rate risks on the transferred financial 
assets. Other than our securitization assets representing these residual 
interests in the trusts’ assets, the investors and the securitization trusts 
have no recourse to our other assets for failure of debtors to pay 
when due. In computing gains and losses on securitizations, we use 
discount rates based on a review of comparable market transactions 
including Level 3 unobservable inputs which consist of base interest 
rates and spreads over these base rates. Depending on the nature 
of the transaction risks, the all-in discount rate ranged from 5.45% 
to 8.34% during the year ended December 31, 2024.
As of December 31, 2024 and December 31, 2023, our managed 
assets totaled $13.7 billion and $12.3 billion, respectively, of which 
$7.1 billion and $6.1 billion, respectively, were securitized assets 
held in unconsolidated securitization trusts or other investors’ portions 
of assets held in co-investment structures. As of December 31, 2024 
and December 31, 2023, the securitization trusts held $6.2 billion 
and $5.6 billion, respectively, of notes due to investors. As of 
December 31, 2024, there were no material payments from debtors 
to the securitization trusts that were greater than 90 days past due. 
Receivables from contracts for the installation of energy efficiency 
and other technologies are the source of cash flows for $116 million 
of our securitization residual assets. These technologies are installed 
in facilities owned by, or operated for or by, federal, state or local 
government entities where the ultimate obligor for the receivable is 
a governmental entity. The contracts may have guarantees of energy 
savings from third-party service providers, which typically are 
entities rated investment grade by an independent rating agency. 
The remainder of our securitization residual assets are related to 
contracts where the underlying cash flows are secured by an interest 
in real estate which are typically senior in terms of repayment to 
other financings.

In 2023, we recorded an allowance for losses on securitization residual assets related to prepayable assets secured by real estate. While there 
is no change in the underlying credit quality of the securitized assets, we have revised our estimates of cash flows due to prepayments on certain 
of these assets. The following table reconciles our beginning and ending allowance for loss on securitization residual assets:

Our Portfolio
As of December 31, 2024, our Portfolio included approximately 
$6.6 billion of equity method investments, receivables, real 
estate and investments on our balance sheet. The equity method 
investments represent our non-controlling equity investments in 
climate solutions projects. The receivables and investments are 
typically collateralized by contractually committed debt obligations 
of government entities or private high credit quality obligors and 
are often supported by additional forms of credit enhancement, 
including security interests and supplier guaranties. The real estate 
is typically land and related lease intangibles for long-term leases 
to wind and solar projects. 
In developing and evaluating performance against our credit criteria, 
we consider a number of qualitative and quantitative criteria which 
may include a project’s operating results, loan-to-value ratio, any 
cash reserves, the ability of expected cash from operations to cover 
the cash flow requirements currently and into the future, key terms of 
the transaction, the ability of the borrower to refinance the transaction, 
the financial and operating capability of the borrower, its sponsors 
or the obligor as well as any guarantors and the project’s collateral 
value. In addition, we consider the overall economic environment, 
the climate solutions sector, the effect of local, industry and broader 
economic factors, the impact of any variation in weather and the 
historical and anticipated trends in interest rates, defaults and loss 
severities for similar transactions.

Receivables 
As of December 31, 2024 our allowance for loan losses related to our receivables was $50 million based on our expectation for credit 
losses over the lives of the receivables in our Portfolio. During 2024, we recorded a benefit for loss on receivables of less than $1 million, 
as the provision related to new loans and loan commitments was offset by a release in the reserves related to loans contributed to a 
co-investment structure.

As of December 31, 2024, this category of assets includes $1.5 billion of mezzanine loans made on a non-recourse basis to bankruptcy-remote special purpose subsidiaries of residential 
solar companies which hold residential solar assets where we rely on certain limited indemnities, warranties, and other obligations of the residential solar companies or their other subsidiaries. 
These residential solar assets typically contain back-up servicer provisions to allow for continuity of operations in the event the project sponsor is unable to fulfill its duties in that capacity. See 
“Related Party Transactions” below for discussion of loans in this category made to special purpose entities that were previously sponsored by the SunPower Corporation.
Risk characteristics of our commercial receivables include a project’s operating risks, which include the impact of the overall economic environment, the climate solutions sector, the effect 
of local, industry, and broader economic factors, the impact of any variation in weather and trends in interest rates. We use assumptions related to these risks to estimate an allowance 
using a discounted cash flow analysis or the PD/LGD method as discussed in Note 2. All of our commercial receivables are included in Performance Rating 1 in the Portfolio Performance 
table above. For those assets in Performance Rating 1, the credit worthiness of the obligor combined with the various structural protections of our assets cause us to believe we have a 
low risk we will not receive our invested capital, however we recorded a $50 million allowance on these $2.9 billion in assets as a result of lower probability assumptions utilized in our 
allowance methodology.
(2)
As of December 31, 2024, our government receivables include $7 million of U.S. federal government transactions and $28 million of transactions where the ultimate obligors are state 
or local governments.
Risk characteristics of our government receivables include the energy savings or the power output of the projects and the ability of the government obligor to generate revenue for debt service, 
via taxation or other means. Transactions may have guarantees of energy savings or other performance support from third-party service providers, which typically are entities, directly or 
whose ultimate parent entity is, rated investment grade by an independent rating agency. All of our government receivables are included in Performance Rating 1 in the Portfolio Performance 
table above. Our allowance for government receivables is primarily calculated by using PD/LGD methods as discussed in Note 2. Our expectation of credit losses for these receivables is 
immaterial given the high credit-quality of the obligors.

Jupiter Equity Holdings, LLC
We have a preferred equity interest in Jupiter Equity Holdings, LLC 
(“Jupiter”) that owns nine operating onshore wind projects and four 
operating utility-scale solar projects with an aggregate capacity 
of approximately 2.3 gigawatts. Through December 31, 2024, 
we have made capital contributions to Jupiter of approximately 
$562 million related to these projects, reflecting final funding true-
ups after all projects reached substantial completion. Alongside 
the project sponsor and under terms outlined in the partnership 
agreement, we have made $94 million in loans to Jupiter for both 
payments related to winter storm Uri as well as payments to allow 
for the restructuring of certain power purchase agreements and tax 
equity arrangements which we expect to increase both near-term 
cash flows and expected lifetime return. Those loans are included 
in our Related Party Transactions disclosures below. The projects 
feature cash flows from fixed-price power purchase agreements 
and financial hedges, contracted with highly creditworthy off-takers 
and counterparties.
Jupiter is governed by an amended and restated limited liability 
company agreement, dated July 1, 2020, by and among the 
members, one of our subsidiaries and a subsidiary of the project 
sponsor, which contains customary terms and conditions. We 
own 100% of the Class A Units in Jupiter corresponding to 
49% of the distributions from Jupiter subject to the preferences 
discussed below. Most major decisions that may impact Jupiter, 
its subsidiaries or its assets, require the majority vote of a four 
person committee on which we and the project sponsor each 
have two representatives. Through Jupiter, we will be entitled to 
preferred distributions until certain return targets are achieved. 
Once these return targets are achieved, distributions will be 
allocated approximately 33% to us and approximately 67% to 
the sponsor. We and the sponsor each have a right of first offer 
if the other party desires to transfer any of its equity ownership to 
a third party. We use the equity method of accounting to account 
for our preferred equity interest in Jupiter, and have elected to 
recognize earnings from this investment one quarter in arrears 
to allow for the receipt of financial information.
Daggett Renewable HoldCo LLC
We have preferred equity interests in Daggett Renewable 
HoldCo LLC (“Daggett”) which owns two utility-scale solar 
projects developed and managed by the project sponsor. We 
have made investments in the preferred cash equity interests of 
Daggett of approximately $232 million through December 31, 
2024, reflecting final funding true-ups after all projects reached 
substantial completion. The Daggett projects feature contracted 
cash flows with a diversified group of predominately investment 
grade utility off-takers.
Daggett is governed by a limited liability company agreement 
between us and the sponsor serving as managing member and 
contain customary terms and conditions. Most major decisions 
that may impact Daggett, its subsidiaries or its assets, require 
a unanimous vote of the representatives present at a meeting 
of a review committee in which a quorum is present. The 
review committee is a four-person committee, which includes 
two of our representatives and two sponsor representatives. 
Commencing on a certain date following the effective date of 
the applicable limited liability company agreement, we will be 
entitled to preferred distributions until certain return targets of 
each investment are achieved. Subject to customary exceptions, 
no member can transfer any of its equity ownership in Daggett 
to a third party without approval of the review committee of 
Daggett. We use the equity method of accounting to account 
for our preferred equity interests in Daggett, and have elected 
to recognize earnings from this investment one quarter in arrears 
to allow for the receipt of financial information.
Lighthouse Renewables HoldCo 2 LLC
We have a preferred equity investment in Lighthouse Renewables 
HoldCo 2 LLC (“Lighthouse 2”) which owns three onshore wind and 
utility-scale solar and solar-plus-storage projects, all developed 
and managed by the project sponsor. We have made investments in 
the preferred cash equity interests of Lighthouse 2 of approximately 
$420 million through December 31, 2024. Alongside the project 
sponsor and under terms outlined in the partnership agreement, we 
have made $18 million in working capital loans to the Lighthouse 
2 primarily for payments related to winter storm Uri. Those working 
capital loans are included in our Related Party Transactions 
disclosures below. The Lighthouse 2 projects feature contracted cash

contain customary terms and conditions. Most major decisions 
that may impact Lighthouse 2, its subsidiaries or its assets, require 
a unanimous vote of the representatives present at a meeting of a 
review committee in which a quorum is present. The review committee 
is a four-person committee, which includes two of our representatives 
and two sponsor representatives. Commencing on a certain date 
following the effective date of the applicable limited liability company 
agreement, we will be entitled to preferred distributions until certain 
return targets are achieved. Subject to customary exceptions, no 
member of Lighthouse 2 can transfer any of its equity ownership in 
Lighthouse 2 to a third party without approval of the review committee 
of Lighthouse 2. We use the equity method of accounting to account 
for our preferred equity interest in Lighthouse 2, and have elected 
to recognize earnings from this investment one quarter in arrears to 
allow for the receipt of financial information.

CarbonCount Holdings 1 LLC
On May 4, 2024, we, through our indirect subsidiary, HASI 
CarbonCount Holdings 1, LLC (“HASI CarbonCount”), a Delaware 
limited liability company, and Hoops Midco, LLC (“KKR Hoops”), 
an investment vehicle established as a Delaware limited liability 
company and managed by an affiliate of Kohlberg Kravis Roberts & 
Co. L.P. (“KKR”), entered into agreements to acquire interests in 
CarbonCount Holdings 1 LLC (“CCH1”), established to invest in 
certain eligible climate positive projects across the United States, 
as further described below. 
CCH1 has been formed as a Delaware limited liability company. 
HASI CarbonCount and KKR Hoops have each committed 
$1 billion to CCH1 to be invested in clean energy assets during 
an 18 month investment period. In addition, HASI, through its 
indirect subsidiaries, HA Securities, LLC (the “Broker-Dealer”) 
and CarbonCount Holdings Manager LLC (the “Asset Manager”, 
and, together with the Broker-Dealer, the “Service Providers”), is 
engaged by CCH1 pursuant to a services agreement (the “Services 
Agreement’) to provide certain services to CCH1.
CCH1 is governed by a board of directors (“the CCH1 Board”) 
which will initially be composed of four directors, two of whom will 
be appointed by us and two of whom will be appointed by KKR 
Hoops. Actions of the CCH1 Board generally require the affirmative 
vote of at least three out of four directors. Pursuant to the service 
agreement, the CCH1 Board has delegated to the Service Providers 
certain rights and powers to manage the day-to-day business and 
affairs of CCH1, while retaining control over the significant decision 
making of CCH1. We account for our investment in CCH1 as an 
equity method investment.
The Broker-Dealer sources investment opportunities for CCH1 
pursuant to the terms of the Services Agreement. Through the 
Broker-Dealer, HASI is obligated to present all of the investment 
opportunities it identifies that fit within certain predetermined criteria 
to the CCH1 Board until either joint venture party’s commitment has 
been fully invested or upon the date that the 18-month investment 
period described above expires or is earlier terminated. The 
investment criteria under the Services Agreement includes investment 
opportunities that we would typically have originated on our 
balance sheet. 
CCH1 pays the Broker-Dealer, for provision of the services 
provided, an upfront fee on each funding of investments generally 
equal to 1% of the total cash consideration funded by CCH1 to 
the applicable investment counterparty. CCH1 also pays the Asset 
Manager, for provision of the services provided by it, ongoing fees 
in respect of asset management and administering the management 
and operation of CCH1, payable when deducted from CCH1’s cash 
available for distribution. The fee payable to the Asset Manager is 
calculated on the basis of certain performance thresholds and will 
generally not be less than 0.5% of invested capital per annum, 
subject to certain limited exceptions, nor more than 1.00%. 
At inception, and prior to KKR’s acquisition of its interest in CCH1, 
we seeded CCH1 with equity method investments and receivables 
which were previously on our balance sheet with a combined book 
value of $108 million, and which are expected to have a total 
invested amount of $191 million once fully funded. We received 
approximately $55 million from KKR for the purchase of their 
share of the net assets of CCH1, resulting in the deconsolidation 
of CCH1 by us. There were no material differences between the 
amounts paid by KKR and the carrying values of the contributed 
assets, resulting in no material gain or loss upon deconsolidation 
and no material basis differences established. Subsequent to the 
KKR’s acquisition of their interest in CCH1, we contributed a further 
$112 million book value of financial assets to CCH1 which were 
previously on our balance sheet, for which we received $61 million 
of cash from KKR. Additionally, we contributed $190 million of 
cash which CCH1 used to make investments. As of December 31, 
2024, CCH1 contains $600 million book value in assets, 81% of 
which are receivables.
CCH1 will recognize income from its equity method investees 
one quarter in arrears to allow for its receipt of financial information.
Other Related Party Transactions
As of December 31, 2024, of our commercial receivables, 
approximately $822 million are loans made to entities in 
which we also have non-controlling equity investments of 
approximately $852 million. Typically, these equity method 
investments are LLCs taxed as partnerships that we have entered 
into with various renewable energy project sponsors, including 
the SunPower Corporation as further described below. We 
negotiate the commercial terms of these loans with the other 
partner, and the assets against which the project sponsors are 
borrowing are contributed into the LLCs upon the execution 
of the loans. Our equity investments allow us to participate in 
the residual economics of those contributed assets alongside 
the other partner, and our rights under the project operating 
agreements do not allow us to make any significant unilateral 
decisions regarding the terms of the arrangement. These assets 
are bankruptcy remote from the project sponsor, and residential 
solar assets typically contain back-up servicer provisions 
to allow for continuity of operations in the event the project 
sponsor is unable to fulfill its duties in that capacity. We are not 
obligated to contribute capital to support these entities, beyond 
agreements to make contributions to allow for the entities to 
purchase additional renewable energy assets. Because the loans 
made to these entities are typically subordinate to senior debt 
and tax equity investors in the projects, these loans, which have 
maturities of over ten years, may accrue PIK interest in the early 
years of the project until sufficient cash flow is available for 
our interest payments. Any change in PIK interest is included 
in Change in accrued interest on receivables and investments 
in the operating section of our statement of cash flows. On 
a quarterly basis, we assess these loans for any impairment 
inclusive of any PIK interest accrued under CECL as discussed 
above under Receivables.

Investments related to SunPower Corporation
On August 5, 2024, SunPower Corporation (“SunPower”), 
a project sponsor for certain of the residential solar projects 
in which we invest, declared Chapter 11 bankruptcy. As of 
December 31, 2024, we have commercial receivables with a 
gross carrying value of $333 million due from special purpose 
entities which own individual residential solar assets (“SunStrong 
SPEs”) for which SunPower performed certain services including 
billing and collections, operations and maintenance, and 
accounting, tax filings, and financial reporting. These SunStrong 
SPEs are bankruptcy remote from SunPower, and were jointly 
owned by SunPower and us. The cash flows supporting our 
loans are from each individual residential customer rather than 
SunPower and are not expected to be materially impacted by this 
event. We evaluate these loans quarterly during our assessment 
of allowance for loan losses, and have determined that our 
allowance for loan losses related to these loans has not been 
materially impacted by these events. 
As of December 31, 2024, we had equity method investments 
of $32 million in the SunStrong SPEs. We have not identified 
any OTTI with regards to these assets, and we do not expect 
our equity method investments in these entities to be materially 
impacted by this ownership change.
In October of 2024, SunPower’s interests in such entities were 
purchased by a third party, who have retained SunPower’s 
governance rights within those structures and who intend to be 
a long-term co-owner of the SunStrong SPEs, and accordingly 
we have continued and will continue to account for our interest 
in these entities as equity method investments. We have taken 
steps to ensure continuation of the services currently provided 
by SunPower, including the engagement of replacement service 
providers. We do not believe the bankruptcy of SunPower will 
have a material impact on our consolidated financial statements.

Credit Facilities and Commercial Paper Notes
Unsecured revolving credit facility
We have an unsecured revolving credit facility pursuant to a 
revolving credit agreement with a syndicate of lenders. In 2024, 
we increased the maximum outstanding borrowing amount of 
the facility from $915 million to $1.35 billion, and extended the 
maturity to April 2028. 
As of December 31, 2024, there were no outstanding borrowings 
under the unsecured revolving credit facility. As of December 31, 
2024, we had less than $9 million of remaining unamortized 
financing costs associated with the unsecured revolving credit 
facility that have been capitalized and included in other assets 
on our balance sheet and are being amortized on a straight-line 
basis over the term of the unsecured revolving credit facility.
The unsecured revolving credit facility has a commitment fee 
based on our current credit rating and bears interest at a rate of 
SOFR or prime rate plus applicable margins based on our current 
credit rating, which may also be adjusted downward up to 0.10% 
to the extent our Portfolio achieves certain targeted levels of 
carbon emissions avoidance as measured by our CarbonCount 
metric. The current applicable margins are 1.625% for SOFR-
based loans and 0.625% for prime rate-based loans, plus an 
additional 0.10%. The unsecured revolving credit facility has a 
commitment fee based on our current credit rating. The unsecured 
revolving credit facility contains terms, conditions, covenants, and 
representations and warranties that are customary and typical 
for transactions of this nature, including various affirmative and 
negative covenants, and limitations on the incurrence of liens and 
indebtedness, investments, fundamental organizational changes, 
dispositions, changes in the nature of business, transactions with 
affiliates, use of proceeds, stock repurchases, and dividends we 
can declare. The unsecured revolving credit facility also includes 
customary events of default and remedies. At our option, upon 
maturity of the unsecured revolving credit facility, we have the 
ability to convert amounts borrowed into term loans for a fee equal 
to 1.625% of the term loan amounts.
Credit-Enhanced Commercial Paper Note Program
We have a Green CarbonCount commercial paper program that 
allows us to issue commercial paper notes at any time, with such 
notes supported by an irrevocable direct-pay letter of credit from 
Bank of America, N.A (“Credit-Enhanced Commercial Paper 
Notes”). In 2024, we increased the capacity of the program 
inclusive of the letter of credit to allow for up to $125 million 
outstanding at any time, and extended the maturity of the program 
and it’s related letter of credit to April 2026. 
83
HASI Form 10-K
Part II
Item 8. Financial Statements and Supplementary Data

Bank of America provides a direct-pay letter of credit to the 
noteholders in the same amount of each Credit-Enhanced 
Commercial Paper Note. The letter of credit is automatically drawn 
upon at maturity of a Credit-Enhanced Commercial Paper Note 
and the noteholders are repaid in full. We have a five business-
day grace period during which we repay Bank of America for the 
amount drawn or issue a new Credit-Enhanced Commercial Paper 
Note. Following the five business-day grace period, any amount 
then-outstanding is converted into a loan from Bank of America. 
Credit-Enhanced Commercial Paper Notes are not redeemable, 
are not subject to voluntary prepayment and are not to exceed 
397 days. The proceeds from our Credit-Enhanced Commercial 
Paper Notes are used to acquire or refinance, in whole or in part, 
eligible green projects, including assets that are neutral to negative 
on incremental carbon emissions. As of December 31, 2024, we 
had no outstanding Credit-Enhanced Commercial Paper Notes. 
Credit-Enhanced Commercial Paper Notes are issued at a discount 
based on market pricing, subject to broker fees of 0.10%. For 
issuance of the letter of credit, we will pay 1.325% on any drawn 
letter of credit amounts to Bank of America, N.A., and 0.35% on any 
unused letter of credit capacity. Any loans converted from drawn 
letter of credit amounts bear interest at a rate of Term SOFR plus 
1.875%, plus an additional 0.10%. Fees paid on the drawn letters 
of credit may be reduced by up to 0.10% to the extent our Portfolio 
achieves certain targeted levels of carbon emissions avoidance as 
measured by our CarbonCount metric. As of December 31, 2024, 
we have no remaining unamortized financing costs associated with 
the commercial paper program and associated letter of credit. The 
associated letter of credit contains terms, conditions, covenants, 
and representations and warranties that are customary and typical 
for a transaction of this nature, including various affirmative and 
negative covenants, and limitations on the incurrence of liens and 
indebtedness, investments, fundamental organizational changes, 
dispositions, changes in the nature of business, transactions with 
affiliates, use of proceeds, stock repurchases and dividends we 
declare. The letter of credit also includes customary events of default 
and remedies.
Standalone Commercial Paper Program
Beginning in 2024, we began to issue unsecured short-term 
promissory notes pursuant to a CarbonCount green commercial 
paper program which are guaranteed by certain of our subsidiaries 
(“Standalone Commercial Paper Notes”). Standalone Commercial 
Paper Notes are issued at a discount based on market pricing, 
subject to broker fees of 0.05%. Standalone Commercial Paper 
Notes are not redeemable, are not subject to voluntary prepayment, 
and are not to exceed 367 days. Our Board has approved the 
issuance of up to $1 billion principal amount of Standalone 
Commercial Paper Notes at any given time. To enhance the credit 
of the Standalone Commercial Paper Notes, we reserve availability 
under our unsecured revolving credit facility for the principal amount 
of any outstanding Standalone Commercial Paper Notes. The 
proceeds from our Standalone Commercial Paper Notes are used 
to acquire or refinance, in whole or in part, eligible green projects, 
including assets that are neutral to negative on incremental carbon 
emissions.
As of December 31, 2024, we had $100 million principal amount 
of Stand-alone Commercial Paper Notes outstanding, which bear 
an average borrowing cost of 5.35%.
Senior secured revolving credit agreement
In 2024, we entered into a senior secured revolving credit agreement 
with a maximum outstanding principal amount of $100 million which 
matures in 2029. Under the terms of the senior secured revolving 
credit agreement, we will pledge collateral to the facility in the form 
of certain qualifying land assets or assets secured by land and will 
be allowed to borrow up to 80% of our cash amount invested in the 
collateral pledged. Any loans under the agreement bear interest at a 
rate of Term SOFR plus 1.90%, and interest is due quarterly. The rate 
of interest can be reduced by up to 0.10% to the extent our Portfolio 
achieves certain targeted levels of carbon emissions avoidance 
as measured by our CarbonCount metric. There is a commitment 
fee of 0.20% of the unused capacity of the agreement, which is 
paid quarterly. The senior secured revolving credit agreement 
contains terms, conditions, covenants, and representations and 
warranties that are customary and typical for transactions of this 
nature, including various affirmative and negative covenants, and 
limitations on the incurrence of liens and indebtedness, investments, 
fundamental organizational changes, dispositions, changes in the 
nature of business, transactions with affiliates, use of proceeds, stock 
repurchases, and dividends we can declare. The senior secured 
revolving credit agreement also includes customary events of default 
and remedies.
As of December 31, 2024, we had no balance outstanding on 
the senior secured revolving credit agreement, and we had 
availability under the revolving credit agreement of $22 million 
based on the pledged collateral. We had approximately $1 million 
in unamortized financing costs associated with the senior secured 
revolving credit agreement, which are included in other assets.

Other non-recourse debt consists of various debt agreements used to finance certain of our receivables. Scheduled debt service payment requirements are equal to or less than the cash flows 
received from the underlying receivables.
(4)
The total collateral pledged against our non-recourse debt was $307 million and $239 million as of December 31, 2024 and December 31, 2023, respectively, which includes $20 million 
and $11 million of restricted cash that was pledged for debt service as of December 31, 2024 and December 31, 2023, respectively.
We have pledged the financed assets, and typically our interests in 
one or more parents or subsidiaries of the borrower that are legally 
separate bankruptcy remote special purpose entities as security for 
the non-recourse debt. There is no recourse for repayment of these 
obligations other than to the applicable borrower and any collateral 
pledged as security for the obligations. Generally, the assets and 
credit of these entities are not available to satisfy any of our other 
debts and obligations. The creditors can only look to the borrower, 
the cash flows of the pledged assets and any other collateral 
pledged, to satisfy the debt and we are not otherwise liable for 
nonpayment of such cash flows. The debt agreements contain terms, 
conditions, covenants, and representations and warranties that 
are customary and typical for transactions of this nature, including 
limitations on the incurrence of liens and indebtedness, investments, 
fundamental organizational changes, dispositions, changes in the 
nature of business, transactions with affiliates, use of proceeds and 
stock repurchases. The agreements also include customary events 
of default, the occurrence of which may result in termination of the 
agreements, acceleration of amounts due, and accrual of default 
interest. We typically act as servicer for the debt transactions. We 
were in compliance with all covenants as of December 31, 2024 
and 2023.
We have guaranteed the accuracy of certain of the representations 
and warranties and other obligations of certain of our subsidiaries 
under certain of the debt agreements and provided an indemnity 
against certain losses from “bad acts” of such subsidiaries including 
fraud, failure to disclose a material fact, theft, misappropriation, 
voluntary bankruptcy or unauthorized transfers.

The stated minimum maturities of non-recourse debt above include 
only the mandatory minimum principal payments. To the extent there 
are additional cash flows received from our investments serving 
as collateral for certain of our non-recourse debt facilities, these 
additional cash flows may be required to be used to make additional 
principal payments against the respective debt. Any additional 
principal payments made due to these provisions may impact the 
anticipated balance at maturity of these financings. To the extent 
there are not sufficient cash flows received from those investments 
pledged as collateral, the investor has no recourse against other 
corporate assets to recover any shortfalls.
Senior Unsecured Notes
We have outstanding senior unsecured notes issued by us or jointly 
by certain of our subsidiaries which are guaranteed by the Company 
and certain other subsidiaries (the “Senior Unsecured Notes”). The 
Senior Unsecured Notes were subject to covenants that limited our 
ability to incur additional indebtedness and required us to maintain 
unencumbered assets of not less than 120% of our unsecured debt. 
These covenants terminated during 2024 as a result of us being 
rated an investment grade issuer by two of the three major credit 
rating agencies and no event of default having occurred. We are in 
compliance with all of our remaining covenants as of December 31, 
2024 and 2023. The Senior Unsecured Notes impose certain 
requirements in the event that we merge with or sell substantially all 
of our assets to another entity. We allocate an amount equal to the 
net proceeds of our Senior Unsecured Notes to the acquisition or 
refinance of, in whole or in part, eligible green projects, including 
assets that are neutral to negative on incremental carbon emissions.

In June 2024, we issued $700 million principal amount of Senior Unsecured Notes due in July 2034 (“2034 Notes”), which bear interest at a rate of 6.375%. The notes were issued for 
gross proceeds of $695 million, resulting in a yield to maturity of 6.476%. We used a portion of the proceeds from this issuance to redeem the outstanding principal amount of the 2025 
notes. There was no premium paid upon redemption. In December 2024, we issued an additional $300 million principal amount of 2034 Notes for gross proceeds of $300 million.

fundamental change. There are no cash settlement provisions for 
the 2025 Exchangeable Senior Notes and the exchange option 
can only be settled through physical delivery of our common 
stock. Upon exchange of the 2028 Exchangeable Senior Notes, 
exchange may be settled through cash, shares of our common 
stock or a combination of cash and shares of our common stock, 
at our election (as described in the indenture related to the 2028 
Exchangeable Senior Notes). Additionally, upon the occurrence 
of certain fundamental changes involving us, holders of the 2025 
Exchangeable Senior Notes or the 2028 Exchangeable Senior 
Notes may require us to redeem all or a portion of their notes 
for cash at a price of 100% of the principal amount outstanding, 
plus accrued and unpaid interest. We may redeem the 2028 
Exchangeable Senior Notes, in whole or in part, at our option, on or 
after August 20, 2026 and prior to the 62nd scheduled trading day 
immediately preceding the maturity date for such notes, if certain 
conditions are met including our common stock trading above 130% 
of the exchange price for at least 20 trading days, as set forth in 
the indenture relating to the 2028 Exchangeable Senior Notes. Any 
shares of our common stock issuable upon exchange of the 2025 
Exchangeable Senior Notes or 2028 Exchangeable Senior Notes 
will have certain registration rights.
We have issued $200 million of 0.00% Exchangeable Senior 
Notes due 2025 which are guaranteed by us and certain of our 
subsidiaries and may, under certain conditions, be exchangeable 
for our common stock. The notes accrete to a premium at maturity 
at an effective rate of 3.25% annually. Upon any exchange of the 
notes, holders will receive a number of shares of our common stock 
equal to the product of (i) the aggregate initial principal amount 
of the notes to be exchanged, divided by $1,000 and (ii) the 
applicable exchange rate, plus cash in lieu of fractional shares. We 
have allocated an amount equal to the net proceeds of this offering 
to the acquisition or refinancing of, in whole or in part, new and/or 
existing eligible green projects, which include assets that are neutral 
to negative on incremental carbon emissions.

In order to mitigate the potential dilution to our common stock upon 
exchange of the 2028 Exchangeable Senior Notes, we entered 
into privately-negotiated capped call transactions (“Capped 
Calls”) with certain counterparties. The Capped Calls are separate 
transactions and are not part of the terms of the 2028 Exchangeable 
Senior Notes. The total premium for the Capped Calls was recorded 
as a reduction of additional paid-in capital. The Company used a 
portion of the proceeds from the 2028 Exchangeable Senior Notes 
to pay for the cost of the Capped Call premium. The material terms

CarbonCount Term Loan Facility
We have entered into a CarbonCount Term Loan Facility (“the 
unsecured term loan facility”) with a syndicate of banks, which has 
an outstanding principal and accrued interest amount of $247 million. 
Principal amounts under the term loan facility bear interest at a 
rate of Term SOFR plus applicable margins based on our current 
credit rating, which may be adjusted downward up to 0.10% to 
the extent our Portfolio achieves certain targeted levels of carbon 
emissions avoidance, as measured by our CarbonCount metric. As 
of December 31, 2024, the applicable margin is 1.875% plus 0.10%, 
and the current interest rate is 6.30%. The coupon on any drawn 
amounts will be reset at monthly, quarterly, or semi-annual intervals 
at our election. Interest is due and payable quarterly. Payments 
of 1.25% of the outstanding principal balance are due quarterly. 
We intend to allocate an amount equal to the net proceeds of this 
offering to the acquisition or refinancing of, in whole or in part, new 
and/or existing eligible green projects, which include assets that are 
neutral to negative on incremental carbon emissions. Loans under the 
unsecured term loan facility can be prepaid without penalty. In 2024, 
we extended the maturity date to 2027, with no changes to the pricing 
terms, and used proceeds from our unsecured revolving credit facility 
to make a partial prepayment of $275 million on the unsecured term 
loan facility to reduce the outstanding principal balance.
Principal and interest payments which were due under the term loan facility as of December 31, 2024 are as follows:

The unsecured term loan facility contains terms, conditions, 
covenants, and representations and warranties that are customary 
and typical for a transaction of this nature, including various 
affirmative and negative covenants, and limitations on the incurrence 
of liens and indebtedness, investments, fundamental organizational 
changes, dispositions, changes in the nature of business, transactions 
with affiliates, use of proceeds, stock repurchases and dividends we 
declare. The unsecured term loan facility also includes customary 
events of default and remedies.
Secured Term Loan
We have a secured term loan (“secured term loan”) with a maturity 
date of January 2028. Principal amounts under the secured term 
loan will bear interest at a rate of Daily Term SOFR plus a credit 
spread of 2.25%, plus 0.10%. We are required to hold interest 
rate swaps with notional values equal to 85% of the outstanding 
principal amount of the loan. The secured term loan is subject 
to mandatory principal amortization of 5% per annum, with 
principal and interest payments due quarterly. The secured term 
loan contains terms, conditions, covenants, and representations 
and warranties that are customary and typical for a transaction of 
this nature, including various affirmative and negative covenants, 
and limitations on the incurrence of liens and indebtedness,

This swap was partially financially settled in 2024 for a benefit of $1 million. Approximately $1 million of this benefit is in AOCI as of December 31, 2024 and will be amortized into interest 
expense over the term of our current floating rate borrowings.

This swap was financially settled in 2024, for a benefit of $19 million. Approximately $18 million of this benefit is in AOCI as of December 31, 2024 and will be amortized into interest expense 
over the term of the 2034 Notes.

The fair values of our interest rate derivatives designated and 
qualifying as effective cash flow hedges are reflected in our 
consolidated balance sheets as a component of other assets (if 
in an unrealized gain position) or accounts payable, accrued 
expenses and other (if in an unrealized loss position) and in net 
unrealized gains and losses in AOCI. As of December 31, 2024, 
all of our derivatives which were designated as hedging instruments 
were deemed to be effective. As of December 31, 2024, we hold 
$57 million of collateral related to our interest rate derivatives that 
are assets, and we have netted the liability associated with that 
collateral against our derivative assets in other assets on our balance 
sheet. As of December 31, 2024, we have posted $8 million worth 
of collateral related to our interest rate derivatives that are liabilities, 
$3 million of which we have netted against our derivative liabilities 
in accounts payable, accrued assets, and other liabilities on our 
balance sheet, with the remaining $5 million in other assets.

Commitments and Contingencies
Leases
We lease office space at our headquarters in Annapolis, Maryland 
under an operating lease entered into in 2021 which expires in 2033. 
In 2023, we entered into a lease for additional office space in New 
York, New York. 
We have a lease related to our previous office space entered into 
in 2011 and amended in 2013 and 2017. Lease payments under 
this prior lease commenced in 2012 and incremental payments 
related to the amendments commenced in 2014 and 2017. The 
lease expires in 2027, and we began subleasing this space 
in 2023. 
The leases provide for operating expense reimbursements and 
annual escalations that are amortized over the respective lease 
terms on a straight-line basis. Rent expense related to these three 
leases was less than $1 million for each of the years ended 
December 31, 2024, 2023, and 2022, respectively. Future gross 
minimum lease payments are approximately $2 million for years 
2025 and 2026, and $1 million per year during the remaining 
term of the leases.
Litigation
The nature of our operations exposes us to the risk of claims and 
litigation in the normal course of our business. We are not currently 
subject to any legal proceedings that are probable of having a 
material adverse effect on our financial position, results of operations 
or cash flows.
Guarantees and other commitments
We have made guarantees related to the financing of four of our 
joint venture entities that own debt securities of energy efficiency 
projects. We received $73 million of the proceeds of this financing 
arrangement, and in turn have guaranteed the obligations of the 
entity related to this financing, which includes collateral posting 
requirements as well as repayment of the financing at maturity in 
May 2025. As of December 31, 2024, our maximum obligation 
under this guarantee is approximately $87 million. We believe the 
likelihood of having to perform under the guarantee is remote, have 
recorded no liability associated with this guarantee, and presently 
have not been required to post collateral for this guarantee as the 
assets of the joint venture entities are enough to support the financing 
obligation. We have executed a separate agreement with our joint 
venture partner pursuant to which it is liable for repayment to us of 
15% of this guarantee obligation.
As a part of broader project restructuring in order to increase our 
expected cash flows from the investment, we alongside the project 
sponsor, made guarantees to support the working capital needs of 
two of the project companies owned by Jupiter, an equity method 
investee. The guarantees are in effect until the tax equity investors in 
those project companies achieve their target preferred returns, and 
our contractual maximum under these guarantees is $53 million, 
and is limited to $20 million in any particular calendar year. As of 
December 31, 2024, we have no liability recorded as a result of 
these guarantees as we believe it is not probable we will be required 
to perform under them. As of December 31, 2024 we have not been 
asked to perform under them.

Item 8. Financial Statements and Supplementary Data

In connection with some of our transactions, we have provided certain limited representations, warranties, covenants and/or provided 
an indemnity against certain losses resulting from our own actions, including related to certain investment tax credits. As of December 31, 
2024, there have been no such actions resulting in claims against the Company.
10. Income Tax
As discussed in Note 1, as a result of expanding opportunities 
in non-qualifying REIT assets, effective January 1, 2024, we 
have elected to revoke our REIT election, and are taxed as a C 
Corporation beginning in tax year 2024. Commencing with the 
taxable year ended December 31, 2024, all of the Company’s 
taxable income is subject to U.S. federal and state income tax at the 
applicable corporate tax rate. Dividends paid to stockholders are no 
longer tax deductible. The Company is also no longer subject to the 
REIT compliance requirements for assets, income, or distributions to 
stockholders among other REIT compliance requirements.
The Company anticipates that operating as a taxable C Corporation 
will provide the Company with flexibility to execute various 
strategic initiatives without the constraints of complying with REIT 
requirements, including increased investing in power generating, 
transportation, and alternative fuel assets that are not REIT 
qualifying. The Company’s transition to a taxable C Corporation is 
not expected to result in significant incremental current income tax 
expense in the near term due to the availability of net operating 
loss (“NOL”) carryforwards and tax credits typically offered by the 
assets in which we often invest. 
We recorded an income tax expense of approximately $70 million 
for the year ended December 31, 2024, a $32 million tax expense 
for the year ended December 31, 2023, and an $7 million tax 
expense for the year ended 2022. The federal income tax expense 
and benefits recorded were determined using a rate of 21%. Our 
deferred tax assets and liabilities were measured using a federal 
rate of 21%. Below is a reconciliation between the federal statutory 
rates and our effective tax rates for the years ended December 31:

Item 8. Financial Statements and Supplementary Data

We have unused NOLs of $841  million and tax credits of 
approximately $40 million. Approximately $87 million of our NOLs 
will begin to expire in 2034. If we were to experience a change 
in control as defined in Section 382 of the Internal Revenue Code, 
our ability to utilize NOLs in the years after the change in control 
would be limited. Similar rules and limitation may apply for state tax 
purposes as well. Of our NOLs, $754 million were added in taxable 
years after 2017 which are not subject to expiration but are limited 
to 80% of taxable income. Our tax credits begin to expire in 2034.
We have no examinations in progress, none are expected at this time, 
and years 2021 through 2024 are open. As of December 2024 and 
2023, we had no uncertain tax positions. Our policy is to recognize 
interest expense and penalties related to income tax matters as a 
component of general and administrative expense. There were no 
accrued interest and penalties as of December 31, 2024 and 2023, 
and no interest and penalties were recognized during the years 
ended December 31, 2024, 2023, or 2022.

Equity Offerings
We have an effective universal shelf registration statement 
registering the potential offer and sale, from time to time and in 
one or more offerings, of any combination of our common stock, 
preferred stock, depositary shares, debt securities, warrants and 
rights (collectively referred to as the “securities”). We may offer the 
securities directly, through agents, or to or through underwriters by 
means of ordinary brokers’ transactions on the NYSE or otherwise 
at market prices prevailing at the time of sale or at negotiated prices 
and may include “at the market” (“ATM”) offerings, to or through 
a market maker or into an existing trading market on an exchange 
or otherwise. We have a dividend reinvestment and stock purchase 
plan, allowing stockholders and holders of OP Units (including LTIP 
Units) to purchase shares of our common stock by reinvesting cash 
dividends or distributions received. We completed the following

Equity-based Compensation Awards
We have 7,500,000 awards authorized for issuance under our current equity-based compensation plan. As of December 31, 2024, we 
have issued awards with service, performance and market conditions and have 5,295,725 awards remaining available for issuance. 
During the year ended December 31, 2024, our Board awarded employees and directors 808,948 shares of restricted stock, restricted 
stock units, and LTIP Units that vest from 2025 to 2029. Refer to Note 4 for background on the LTIP Units.

NOL Stockholder Rights Plan
In 2023, we established a Tax Benefits Preservation Plan 
(“the Plan”), which was designed to protect our tax benefits in 
connection with any “ownership change” within the meaning of 
Section 382 of the Internal Revenue Code of 1986. Under the 
Plan, we declared a dividend distribution of one right (a “Right”) 
for each outstanding share of our common stock to be paid to 
all record holders of our common stock at the close of business 
on November 21, 2023. The Plan was intended to reduce the 
risk that our ability to use net operating losses (“NOLs”) and 
certain other Tax Benefits would have substantially limited as 
the result of an “ownership change”. As of December 31, 2023, 
we had approximately $666 million of NOLs and $31 million 
of tax credits available that may be used to offset future taxable 
income. On July 1, 2024, we entered into an amendment which 
caused the Rights under the Plan to expire on July 1, 2024, 
effectively terminating the Plan at that time in anticipation of the 
effectiveness of the Company’s reincorporation as a Delaware 
corporation on July 2, 2024. The Company’s Delaware Certificate 
of Incorporation includes Charter Tax Benefit Provisions which are 
intended to replace the Tax Benefits Preservation Plan.
Pursuant to the Plan, during the period in which it existed, if a 
stockholder (or group) became a 5% stockholder without meeting 
certain exceptions, the Rights became exercisable upon board 
approval and entitled stockholders (other than the 5% stockholder 
or group causing the Rights to become exercisable) to purchase 
additional of our common shares at a significant discount, resulting 
in significant dilution in the economic interest and voting power 
of the 5% stockholder or group causing the Rights to become 
exercisable. Stockholders owning 5% or more of our outstanding 
95
HASI Form 10-K

Item 8. Financial Statements and Supplementary Data

shares at the time the Plan was adopted were grandfathered 
and would have only caused the Rights to distribute and become 
exercisable if they acquire any additional HASI shares. Under the 
Plan, the Board had the ability to determine in its sole discretion 
that any person shall not be deemed an acquiring person and 
therefore that the Rights shall not become exercisable if such 
person becomes a 5% stockholder. The adoption and termination 
of the Plan and the dividend distribution did not have an impact 
on our consolidated financial statements.
12.
Earnings per Share of Common Stock
The net income or loss attributable to the non-controlling OP units 
have been excluded from the basic earnings per share and the 
diluted earnings per share calculations attributable to common 
stockholders. Unvested share-based payment awards that 
contain non-forfeitable rights to dividends or dividend equivalents 
(whether paid or unpaid) are participating securities and are 
excluded from net income available to common stockholders 
in the computation of earnings per share pursuant to the two-
class method. Certain share-based awards are included in the 
diluted share count to the extent they are dilutive as discussed in 
Note 2. To the extent our Convertible Notes are dilutive under 
the if-converted method, we add back the interest expense to the 
numerator and include the weighted average shares of potential 
common stock over the period issuable upon conversion or 
exchange of the note in the denominator in calculating dilutive 
EPS as described in Note 2. 
The computation of basic and diluted earnings per common share of our common stock is as follows:

13. Equity Method Investments
During the years ended December 31, 2024, 2023, and 2022 we 
recognized income of $248 million, $141 million, and $31 million 
respectively, from our equity method investments. We describe our 
accounting for the non-controlling equity investments in Note 2. As 
of both December 31, 2024 and December 31, 2023, we had 47 
investments which we accounted for under the equity method. The 
majority of these investees are limited liability companies taxed as 
partnerships wherein we participate in cash distributions and tax 
attributes according to pre-negotiated profit-sharing arrangements. 
The limited liability company agreements do not define a fixed 
percentage of our ownership of these entities, and our claims on 
the net assets of each investment changes over time as preferred 
investors achieve their pre-negotiated preferred returns.
The following is a summary of the consolidated balance sheets and 
income statements of the entities in which we have a significant equity 
method investment. These amounts are presented on the underlying 
investees’ accounting basis. In certain instances, adjustment to these 
equity values may be necessary in order to reflect our basis in these 
investments, for reasons including but not limited to the investees 
reporting to us being on a cost basis rather than a fair value basis or 
due to our allocations under HLBV differing from our purchase price 
of the investment. As described in Note 2, any difference between the 
amount of our investment and the amount of our share of underlying 
equity is generally amortized over the life of the assets and liabilities 
to which the differences relate. Our basis in equity method investments 
exceeds the basis reported to us by our investees by an aggregate 
amount of $104 million, and $284 million, as of December 31, 2024 
and 2023, respectively. Certain of the projects in which we have 
equity method investments also have interest rate swaps which are 
designated as cash flow hedges, and we recognize the portion of 
the gain or loss allocated to us related to those instruments through 
other comprehensive income. As of December 31, 2024 and 2023, 
we have accumulated other comprehensive income net of tax effect 
of $23 million and $47 million respectively, related to the interest rate 
swaps designated as cash flow hedges by our investees.

Controls and Procedures
A review and evaluation was performed by our management, 
including our chief executive officer and chief financial officer, of the 
effectiveness of the design and operation of our disclosure controls 
and procedures (as such term is defined in Rules 13a-15(e) and 
15d-15(e) under the Exchange Act), as of the end of the period 
covered by this Form 10-K. Based on that review and evaluation, 
the chief executive officer and chief financial officer have concluded 
that our current disclosure controls and procedures, as designed 
and implemented, were effective. Notwithstanding the foregoing, 
a control system, no matter how well designed and operated, 
can provide only reasonable, not absolute, assurance that it will 
detect or uncover failures within our company to disclose material 
information otherwise required to be set forth in our periodic reports.
Management’s Report on Internal Control 
Over Financial Reporting
Our management is responsible for establishing and maintaining 
adequate internal control over financial reporting. Internal control 
over financial reporting is defined in Rules 13a-15(f) and 15d-15(f) 
promulgated under the Exchange Act as a process designed by, 
or under the supervision of, our principal executive and principal 
financial officers and effected by our Board, management and other 
personnel to provide reasonable assurance regarding the reliability 
of financial reporting and the preparation of financial statements 
for external purposes in accordance with U.S. GAAP and includes 
those policies and procedures that:
• pertain to the maintenance of records that in reasonable detail 
accurately and fairly reflect the transactions and dispositions of 
the assets of our company;
• provide reasonable assurance that transactions are recorded 
as necessary to permit preparation of financial statements in 
accordance with U.S. GAAP, and that our receipts and expenditures 
are being made only in accordance with authorizations of our 
management and directors; and
• provide reasonable assurance regarding prevention or timely 
detection of unauthorized acquisition, use or disposition of our 
assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial 
reporting may not prevent or detect misstatements. Projections of 
any evaluation of effectiveness to future periods are subject to the 
98
HASI Form 10-K
Part II
Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

risks that controls may become inadequate because of changes 
in conditions or that the degree of compliance with the policies or 
procedures may deteriorate.
Our management assessed the effectiveness of our internal control 
over financial reporting as of December 31, 2024. In making this 
assessment, our management used criteria set forth by the Committee 
of Sponsoring Organizations of the Treadway Commission in 
Internal Control-Integrated Framework (2013 Framework).
Based on this assessment, our management believes that, as of 
December 31, 2024, our internal control over financial reporting 
was effective based on those criteria.
Changes in Internal Control Over Financial 
Reporting
There have been no changes in our internal control over financial 
reporting that occurred during the quarter ended December 31, 
2024 that have materially affected, or are reasonably likely to 
materially affect, our internal control over financial reporting.
Our company’s independent registered public accounting firm, Ernst 
& Young LLP, has issued an attestation report on the effectiveness of 
our company’s internal control over financial reporting. This report 
appears on page 67 of this annual report on Form 10-K.

Mr. Melko will transition from the Company’s Chief Accounting 
Officer to the Company’s Chief Financial Officer, effective 
March 1, 2025. 
In connection with this transition, Mr. Melko’s employment 
agreement has been amended and restated with HA Sustainable 
Infrastructure Capital Inc. (instead of with Hannon Armstrong 
Sustainable Infrastructure Capital Inc.) and includes an annual 
base salary of $400,000 and a target annual bonus of 110% of 
Mr. Melko’s base salary. Mr. Melko will be eligible to receive equity 
compensation awards when awards are made to similarly situated 
senior executives of the Company.
If Mr. Melko is terminated due to his disability or death, Mr. Melko 
or his estate will receive any accrued but unpaid annual base 
salary, annual bonus and benefits, plus a pro rata target bonus for 
the year in which his termination of employment occurs (in the case 
of death) and a target annual bonus for the fiscal year in which 
the employee’s termination occurs (in the case of disability). All 
outstanding equity awards held by Mr. Melko will become vested 
and nonforfeitable. 
If Mr. Melko is terminated without cause or leaves employment for 
good reason, he will be entitled to severance equal to his accrued but 
unpaid annual base salary, annual bonus and benefits and a lump 
sum payment of 12 months of his annual base annual salary and 
100% of the average of his annual bonus received for the previous 
three fiscal years prior to the termination. All outstanding equity 
awards held by Mr. Melko will become vested and nonforfeitable. 
For up to 12 months following such a termination, we will subsidize 
the cost of Mr. Melko’s post-employment health coverage.
If Mr. Melko is terminated for cause or leaves employment without 
good reason, he will be entitled to any accrued but unpaid annual 
salary, annual bonus and benefits. 
Mr. Melko’s reporting lines will now include all of the Company’s 
accounting and finance departments which will report to him.

includes a change in target annual bonus from 150% to 100% and 
change in severance entitlement. Mr. Rose’s annual base salary 
remains unchanged from his 2024 annual base salary at $420,000. 
Mr. Rose’s prior severance entitlement was if Mr. Rose was 
terminated without cause or leaves employment for a good reason, 
he was entitled to (a) 24 months post-termination continuing medical 
benefits cover and (b) all outstanding equity awards held by 
Mr. Rose will become vested and nonforfeitable on termination and 
(c) a lump sum severance pay of accrued but unpaid annual base 
salary, annual bonus and benefits and an amount equal to the sum 
of 1.5 x (i) Mr. Rose’s annual base salary (at time of termination) and 
(ii) the higher of Mr. Rose’s average annual bonus actually received 
in respect of the final three fiscal year pre-termination and Mr. Rose’s 
target annual bonus for fiscal year in which the termination occurs. 
Mr. Rose’s new severance entitlement on termination without cause 
or if he leaves employment for good reason will be (a) up to 18 
months post-termination, we will subsidize the cost of Mr. Rose’s 
post-employment health coverage and (b) all outstanding equity

In 2013, we adopted our 2013 Equity Incentive Plan (the “2013 Plan”) and in 2022, we adopted our 2022 Equity Incentive Plan (the “2022 
Plan”), to provide equity-based incentive compensation to members of our senior management team, our independent directors, advisers, 
consultants and other personnel. The 2022 Plan authorizes our compensation committee to grant stock options, shares of restricted common 
stock, restricted stock units, phantom shares, dividend equivalent rights, LTIP Units and other restricted limited partnership units issued by 
our Operating Partnership and other equity-based awards. Up to 7,500,000 equity awards may be issued under the 2022 Plan. Upon 
the adoption of the 2022 Plan, no further awards were permitted to be granted under the 2013 Plan.
As of December 31, 2024, in the aggregate under the 2013 Plan and 2022 Plan, we have approximately 2.2 million shares of our restricted 
common stock, LTIP Units, and restricted common stock units outstanding (assuming that the restricted stock units vest at 200%), which are
