We have elected to take advantage of the Securities and Exchange Commission’s rules that allow us to furnish our proxy materials to

smaller volume, will reduce the environmental impact of our annual meeting materials and help lower our costs. A Notice of Internet
Availability of Proxy Materials (the “Notice of Internet Availability”) is being mailed concurrently to our stockholders. The Notice of
Internet Availability contains instructions on how to access the Notice of Annual Meeting, Proxy Statement and Annual Report to
Stockholders online. You will not receive a printed copy of these materials unless you specifically request one. The Notice of Internet
Availability contains instructions on how to receive a paper copy of the proxy materials. It is important that your shares be
represented and voted at the meeting.
You may vote your shares in person at the meeting, by Internet, by telephone or by completing, signing, dating and returning a proxy
card which will be mailed to you if you request delivery of a full set of proxy materials.

SUMMARY PROXY INFORMATION
Summary Proxy Information
This statement is furnished in connection with the solicitation by the Board of Directors of AAON, Inc., for proxies to be used at our
Annual Meeting to be held on May 13, 2025, at the time and place set forth in the Notice of Annual Meeting accompanying this Proxy
Statement. Unless the context otherwise requires, references herein to “AAON”, “we”, “us”, “our” or “ours” refers to AAON, Inc., a
Nevada corporation.
Pursuant to provisions of our Bylaws (the "Bylaws") and action of our Board of Directors, the close of business on March 14, 2025,
has been established as the time and record date for determining the stockholders entitled to notice of and to vote at this Annual
Meeting. The stock transfer books will not be closed.
Stockholders of record on the record date are entitled to cast their votes at the Annual Meeting in person or by internet, telephone or
properly executed proxy. The presence, by any of these means, of at least a majority of the Common Stock outstanding on the record
date is necessary to constitute a quorum at the Annual Meeting. Abstentions and broker non-votes are counted as shares present in
determining whether the quorum requirement is satisfied. If a quorum is not present at the time the Annual Meeting is convened, we
may adjourn or postpone the meeting.
Proxy Statement Summary
Determination of whether a proposal specified in the Notice
of Annual Meeting has been approved will be determined,
assuming a quorum is present either in person or by proxy,
as follows:
Proposal No. 1.
A nominee for director will be elected if a majority of the votes
cast are in favor of such nominee’s election. Accordingly,
abstentions and broker non-votes will have no effect on the
outcome of the vote on the director nominees.
Proposal No. 2.
The proposal to ratify Grant Thornton LLP as our independent
registered public accounting firm for the year ending
December 31, 2025, will require the affirmative vote of a
majority of the votes cast on the proposal. Accordingly,
abstentions will have no effect on the outcome of the vote on
this proposal. Brokers have discretionary authority and may
vote on the proposal without having instructions from the
beneficial owners or persons entitled to vote thereon.
Proposal No. 3.
The proposal to approve, on an advisory basis, the
compensation of our named executive officers will require the
affirmative vote of a majority of the votes cast on the proposal.
Accordingly, abstentions and broker non-votes will have no
effect on the outcome of the vote on this proposal.
YOU MAY VOTE IN SEVERAL DIFFERENT WAYS:
In Person at the Annual Meeting
You ma y vote in person at the Annual Meeting. You may
also be represented by another person at the meeting by
executing a proxy properly designating that person. If you are
the beneficial owner of shares held in “street name,” you must

record and present it to the inspectors of election with your
ballot to be able to vote at the meeting.

indicated on the voting instructions you will receive.
Easy-to-follow voice prompts allow you to vote your
shares and confirm that your voting instructions have been

SUMMARY PROXY INFORMATION
mailed proxy card must be received by May 12, 2025, in order
to be voted at the Annual Meeting. The availability of
telephone and Internet voting for beneficial owners of other
shares held in “street name” will depend on your broker, bank
or other holder of record and we recommend that you follow
the voting instructions on the Notice of Internet Availability that
you receive from them.
If you are mailed a set of proxy materials and a proxy card or
voting instruction card and you choose to vote by telephone or
by Internet, you do not have to return your proxy card or
voting instruction card. However, even if you plan to attend
the Annual Meeting, we recommend that you vote your shares
in advance so that your vote will be counted if you later decide
not to attend the meeting.
Proxies received in advance of the meeting may be revoked
at any time prior to the voting thereof, either by giving notice
to the Secretary of AAON or by personal attendance at the
meeting.
We have adopted a procedure approved by the SEC called
“householding” pursuant to which stockholders of record who
have the same address and last name and who request a
written copy of our Annual Report and Proxy Statement will
receive only one copy of such materials unless one or more of
these stockholders notify us that they wish to receive
individual copies. Stockholders who participate in
householding will continue to receive separate proxy cards.
We will pay the costs of the solicitation of proxies. We may
reimburse brokerage firms and other persons for expenses
incurred in forwarding the proxy materials to their customers
who are beneficial owners and obtaining their voting
instructions. Stockholders electing to vote over the Internet
should understand that there may be costs associated with
electronic access (such as charges from their Internet access
provider) and that these costs must be borne by the
stockholder.
Stockholders currently receiving multiple copies of our Annual
Report and Proxy Statement at their household can request
householding by contacting our transfer agent at
1-800-736-3001 or writing to Computershare, PO Box 43006,
Providence, RI 02940-3006. Stockholders now participating
in householding who wish to receive a separate document in
the future may do so in the same manner. Those owning
shares through a bank, broker or other nominee may request
householding by contacting the nominee.
This Proxy Statement, the Notice of Annual Meeting and
accompanying proxy card, as well as our 2024 Annual Report
(which includes our Annual Report on Form 10-K for the year
ended December 31, 2024), can also be found at our website
(www.aaon.com). Copies of exhibits omitted from the Annual
Report on Form 10-K are available without charge upon
written request to Investor Relations, 2425 S. Yukon Avenue,
Tulsa, Oklahoma 74107, or may also be obtained at the
Securities and Exchange Commission’s website at
www.sec.gov.
We recognize the importance our stockholders place on the
Annual Meeting and also appreciate the opportunity it affords
for them to engage with senior management. We also
understand that it provides a convenient forum for our
stockholders to acquire first-hand exposure to, and ask
questions of our management. In an attempt to preserve the
benefits of the traditional meeting format, while also
recognizing not all stockholders can attend in person, we
suggest that our stockholders not able to attend in person
consider availing themselves of the following opportunities:
Questions for Management
Stockholders are encouraged to submit questions for
management without having to attend the Annual Meeting in
person. To do so, questions may be submitted to
annualmeeting@aaon.com. Appropriate questions will be
presented for management to respond at the Annual Meeting.
We retain discretion to reject questions that are improper,
irrelevant, substantially similar to questions submitted by other
stockholders or are otherwise derogatory or not in good taste.
Recording of Management Presentation and Q&A

In Share
Repurchases
During 2024, our executive officers led our efforts to increase sales, executed our internal capital expenditure programs and
positioned the Company to capitalize on anticipated growth. Some of the key accomplishments during 2024 include:
Financial Performance
The Company ended the year with a backlog of $867.1 million, up 70.0% compared to December 31, 2023. The increase is the result
of the increased demand in the data center market. In the fourth quarter of 2024, the Company received over $200.0 million in orders
for the BASX branded data center liquid cooling solutions. The overwhelming demand for BASX branded products also helped drive
net sales growth of 2.7% to $1,200.6 million for the year ended December 31, 2024.
Expansion and Growth
We had record capital expenditures for the year ended December 31, 2004 of $195.7 million. These investments funded our
expansions across multiple facilities. We added 237,500 square feet to our Longview, Texas facility primarily for the production of
BASX branded data center products. We also completed the addition of a new Weld Shop in Redmond, Oregon that created more
capacity in our manufacturing building. In Parkville, Missouri, we built an SMT production line to produce our own control boards. We
have also made investments to purchase and develop software for internal use in anticipation of future Company growth. In
December 2024, the Company purchased a new 787,000-square-foot facility in Memphis, Tennessee, which will accommodate
incremental demand for both BASX and AAON products over the next several years, at the same time providing more geographic
diversification across our manufacturing footprint. The purchase price for the facility was approximately $63.4 million.
Total Shareholder Return (TSR)
The market price of our common stock was $117.68 per share on December 31, 2024, an increase of approximately 59.3% from the
closing price of $73.87 on December 29, 2023. We generated TSR of approximately 143.2% from January 1, 2022, through
December 31, 2024. This return exceeded the returns over the same period of 38 of 48 companies in the S&P 600 Capital Goods
Index.
Dividends and Stockholder Returns
We are committed to returning value to our stockholders. We make quarterly dividend payments with increases as needed. We want
to reward long-term stockholders through share buybacks. When we have excess cash, we work to repurchase shares and decrease
our share count. In 2024, we completed the repurchase of 1.4 million shares in the open market for $100.0 million at an average
price of $73.90.

SUMMARY PROXY INFORMATION
Compensation Highlights
Compensation Philosophy
Our Compensation Committee determines executive compensation based on a comprehensive review of quantitative and qualitative
factors designed to reward the accomplishment of long-term sustainable business goals. Our executive compensation program is
designed to attract, engage, motivate, reward and retain highly effective key executives who drive our success and are industry
leaders. Our pay-for-performance programs align our executive officers’ long-term interests with those of our stockholders. Additional
information can be found in the Compensation Discussion and Analysis beginning on page 30.
Program Design
The Compensation Committee references market data when determining all compensation elements and targets the median level of
total compensation. Our compensation program provides a competitive total compensation opportunity by establishing a pay mix that
balances short- and long-term performance specifically involving significant equity-based (at-risk) compensation. A significant portion
of total compensation is linked to performance, which we believe creates long-term stockholder value and discourages unnecessary
or excessive risk taking. Our performance-based annual incentive bonus program provides cash awards based on achievement of
the Company’s annual financial and operational goals, as well as individual performance of each Named Executive Officer ("NEO").
We encourage alignment of our NEOs’ interests with those of our stockholders through long-term incentive awards, which are
comprised of approximately 50.0% Performance Stock Units ("PSU"), 25.0% Options and 25.0% Restricted Stock Awards ("RSA").
Our NEOs receive limited perquisites and no other personal benefits. Perquisites are limited to executive physicals for our NEOs,
which aligns with our wellness initiatives and assist in mitigating risk. We have market-competitive stock ownership policies for our
NEOs and our non-management directors, which provides them with a significant stake in our long-term success and aligns their
interests with stockholder interests.
Say-On-Pay
Our say-on-pay vote in 2024 was 96.8% in agreement with the compensation paid to our NEOs. While we aim to continuously
improve our pay practices, we are pleased with the positive feedback from our stockholders and their strong historical endorsement
of our executive compensation program, which is reflected in the average of 95.2% favorable votes over the past three years. In
reviewing our compensation program during 2024, our Compensation Committee determined to continue applying the same
principles as have been historically applied in determining the nature and amount of our executive compensation.

CORPORATE RESPONSIBILITY
Corporate Responsibility
Our Company is widely recognized as a leader in the design, manufacture, and sale of energy-efficient Heating, Ventilation and Air
Conditioning ("HVAC") products. Our product offerings include some of the most energy-efficient products in our industry. We have a
proud history of challenging conventional wisdom and forging our own path through a never-ending commitment to innovation and
continuous improvement of our products and manufacturing methodologies. These underlying principles guide our commitment to
environmental stewardship, sustainability and social responsibility. We endeavor to utilize Company resources in a manner that
creates long-term value for our stockholders while minimizing our impact on natural resources and the environment.
We established a Sustainability Steering Committee led by Stephanie Regan, our Director of Corporate Citizenship, which includes
representatives from most functional areas, including other members of our senior management team. The primary purpose of the
Sustainability Steering Committee is to improve sustainability reporting and increase engagement in overall sustainability actions.
The Committee regularly provides education opportunities, communications and recommendations to senior management and the
B oard. In 2024, we continued work toward the following goals:
1.Reduce greenhouse gas emissions by 10% by 2025 from a 2020 baseline
2.Increase paint materials recycling rate by 10% by 2025 from a 2020 baseline
3.80% of total equipment sales will be non-fossil fuel-consuming products by 2030
Environmental Performance
At AAON, it is our priority to do business in a socially responsible and ethical manner as we continuously improve our environmental
stewardship. We are committed to reducing our greenhouse gas emissions ("GHG") through operational efficiencies and project
investments within our locations and surrounding communities that reduce carbon emissions. We understand that climate change is
one of the most significant challenges facing humanity across the globe, affecting every aspect of our lives, and AAON aims to be
part of the solution. This is not only necessary for the well-being of future generations but also drives innovation and creates
opportunities for job creation and economic growth.
Our approach to overall environmental long-term sustainability efforts includes the following:

Operational Efficiency and Investments | Research and Development Lead to Industry Innovation | Identifying Risks to Business and Industry | Industry Collaboration and Leadership | Commitment to Sustaining Communities and Natural Resources
AAON recognizes that investments in its facilities, employees, and governance in a clean, safe, and environmentally conscious manner are critical to long-term sustainability. | Our research and development leads the charge in energy efficient innovations to meet increasing decarbonization demands and to help AAON customers meet their sustainability goals. | AAON proactively works with internal and external stakeholders to identify and address risks that could affect our business and industry.

CORPORATE RESPONSIBILITY
As AAON grows at a rapid pace, managing and improving our
overall manufacturing operations for long-term sustainability is
critical to our core business. For AAON and the HVAC
industry, the most impactful factor on people and society is
the HVAC equipment we manufacture. Commercial buildings
comprise 16% of the total carbon emissions in the U.S., and
approximately 40% of those emissions are related to building
HVAC systems.
AAON’s 2024 Sustainability report focuses on material topics
with reference to the Global Reporting Initiative ("GRI")
Standards, the Sustainability Accounting Standards Board
("SASB") standards, the UN Global Company, the Task Force
on Climate-Related Financial Disclosures and the United
Nations Sustainable Development Goals ("SDG") frameworks.
AAON conducts internal audits reviewing the supporting
documentation for the data and verifying the evidence. The
Company regularly evaluates and aligns its strategy and
reports against the highest number of corporate responsibility
topics for our business and stakeholders. This drives how we
engage internally and externally, invest resources, and adapt
our strategy on environmental, social, economic, and
governance topics.
We are a proud participant in The Sustainability Alliance
Scor3card sustainability verification program and continuously
work to improve our environmental and social impact. AAON
works to not only maintain its Platinum-level Scor3Card rating,
but by participating in the program, we continue our
commitment to measure and improve performances. The
Company received a Platinum score in 2024, 2023, 2022,
2021 and 2020, Gold in 2019, and Bronze in 2018. A
Scor3card Platinum level requires completing more than 85%
of eligible directives in the categories of: Communication,
Community, Resilience, Energy, Healthy Work Environment,
Material Management, Transportation, Water, Diversity and
Inclusion Other honors AAON has received include:
•Named by Newsweek Magazine in the top 300 U.S.
companies based on environmental sustainability
through greenhouse gas emissions, water usage,
water generation, waste generation, and
sustainability data disclosure and commitments.
(Partnership with Plant-A and GIST Impact)
•Named by USA Today as one of America's Climate
Leaders for 2024, recognizing companies that cut
their carbon footprint in recent years.
We are committed to environmental responsibility and
continue to make progress toward reducing GHG emissions,
increasing paint material recycling from our facilities and
increasing the percentage of non-fossil fuel powered units we
produce. Our approach toward emissions reduction and
climate change includes product solutions for our customers
and improvements to our own facilities. Approximately 36.0%
of our energy portfolio is currently derived from renewable
sources, and the Company’s Scope 1 and 2 emissions
(emissions that occur from sources that are controlled or
owned by an organization and emissions associated with the
purchase of electricity, steam, heat, or cooling) are being
tracked. We have opted into an additional renewable energy
at our Tulsa, Oklahoma and Redmond, Oregon facilities in
2024, continued to invest and partner on projects that reduce
GHG emissions globally and transitioned to the lower global
warming potential R-454B refrigerant.
Our Products
We continue to develop and manufacture non-fossil fuel
consuming units to provide the most sustainable commercial
HVAC equipment in the market and announced the zero-
degree cold air-source heat pump in 2022 as a critical solution
that meets the increasing demand for building
decarbonization in cold climates. Our AAON Alpha Class
product line is leading the charge towards sustainable HVAC
solutions, with more efficient technology that propels the
decarbonization movement forward. AAON Alpha Class air-
source heat pumps, available in capacities ranging from two
to seventy tons, offer exceptional versatility and industry-
leading features to meet the growing environmental and
regulatory needs. The Company’s premier HVAC solution is
highly configurable and optimized for diverse environments. It
features variable speed compressor technology, all-electric or
dual-fuel options, Dedicated Outdoor Air System ("DOAS")
capability, energy recovery, and low global warming potential
refrigerant. The AAON Alpha Class is engineered for higher
efficiency and lower emissions, utilizing the same double-wall
rigid polyurethane foam-injected panel construction that
AAON is known for, which helps retain useful heating and
cooling energy within the building. With its first-of-its-kind
omni-climate performance, the AAON Alpha Class offers the
innovation that our future demands.
Our Facilities
At our Tulsa, Oklahoma location, we have the Exploration
Center and Norman Asbjornson Innovation Center ("NAIC").
The Exploration Center opened in 2023 and is a 28,000-
square-foot facility located adjacent to the NAIC. The
Exploration Center is a Net-zero facility using advanced
building systems, including photovoltaic (solar) electricity
generation, geothermal fields and AAON high-efficiency heat
pumps, while providing a world-class experience for
stakeholders. AAON achieved a milestone achievement in its
sustainability journey by activating 432 solar panels on the
roof of the Exploration Center and NAIC. These panels
generate about 240 kW of solar energy, contributing to being
8
CORPORATE RESPONSIBILITY
one of the most sustainable, energy-efficient buildings in
Tulsa. As part of its design, the infrastructure can support up
to 800+ kW of solar generation, one of the largest in
Oklahoma.
In the area of energy efficiency and conservation, our Tulsa,
Oklahoma and Longview, Texas facilities have transitioned to
over 98.0% LED lighting in our facilities leading to
considerable cost savings and reduced energy consumption.
Our Redmond, Oregon facilities are installing LED lights into
any new fixtures in their current facility and working towards
retrofitting old fixtures to LED. We participate in an energy
demand response program through the public utility provider
to reduce demand during peak hours. Energy efficiency has
been a priority not only in product development, but also in
overall capital investments which include the acquisition of
new, energy-efficient equipment for the production floor, new
high-speed overhead facility doors, the installation of new
HVAC equipment, building control systems, the application of
heat and light reflective material to production facilities, along
with other behavioral-based energy efficiency changes. We
are tracking our energy usage intensity before and after these
updates.
In the area of material management, we focus on recycling,
reducing, reusing and sourcing more environmentally friendly
materials into our processes. At our Tulsa, Oklahoma and
Longview, Texas facilities, we recycled over 15,715 tons and
13,678 tons of metal in 2024 and 2023, respectively. Also,
through our partnership with a waste-to-energy facility, we
successfully diverted over 3,020 tons and 694 tons of waste
from landfills in 2024 and 2023, respectively. The Company
has identified paint recycling partners at both the Tulsa,
Oklahoma and Longview, Texas facilities. We also recycle
paper, wood, and cardboard where available. We continue to
innovate ways to reduce and reuse shipping packaging
between facilities and identify new opportunities to reduce or
reuse items in our production and administrative areas.
Community Investment
We strive to add value and support to the communities in which our employees live and work, through financial contributions,
employee volunteerism and donations. AAON is dedicated to corporate social responsibility to create a meaningful impact centered
around the communities in which we operate. We recognize that our success is interwoven with the vitality of communities as we
apply our assets, resources, and capabilities to contribute to their resiliency and prosperity. Our community priorities are workforce
readiness, strong families and communities and environmental stewardship.
We strengthen the communities in which we operate in the following ways:
•AAON has a Matching Gift s Program to further support team members' donations to nonprofits of their choice.
•As part of our AAON Serves program, employees receive 24 paid volunteer hours.
•AAON actively supports education and workforce readiness programs. Our locations hosted and engaged more than 500

GOVERNANCE OF THE COMPANY
Governance of the Company
Code of Business Conduct and Ethics
We have adopted a Code of Business Conduct and Ethics that applies to our principal executive officer, principal financial officer and
principal accounting officer or persons performing similar functions, as well as our other employees and directors. Our Code of
Business Conduct and Ethics can be found on our website at www.aaon.com and is also available from our corporate secretary upon
request.
Director Independence
The Board has adopted director independence standards that
meet and/or exceed listing standards set by NASDAQ.
NASDAQ has set forth six applicable tests and requires that a
director who fails any of the tests be deemed not independent.
The Board has affirmatively determined that Ms. Kouplen, Ms.
Lawhorn and Messrs. LeClair, McElroy, Stewart and Ware are
independent under the Company's guidelines and
independence standards of NASDAQ and the SEC. Messrs.
Asbjornson and Fields do not qualify as independent under the
standards set forth below.
Our director independence standards are as follows:
It is the policy of the Board that a majority of the members of
the Board consist of directors independent of AAON and our
management. For a director to be deemed “independent,” the
Board must affirmatively determine that (apart from his or her
status as a director) the director has no material relationship
with AAON or its affiliates or any member of the senior
management of AAON or his or her affiliates. In making this
determination, the Board applies, at a minimum and in addition
to any other standards for independence established under
applicable statutes and regulations as outlined by the NASDAQ
listing standards, the following standards, which it may amend
or supplement from time to time:
A director who is, or has been within the last three years, one
of our employees, or whose immediate family member is, or
has been within the last three years a Named Executive
Officer, cannot be deemed independent. Employment as an
interim Chair or Chief Executive Officer will not disqualify a
director from being considered independent following that
employment.
A director who has received, or who has an immediate family
member who has received, during any twelve-month period
within the last three years, more than $120,000 in direct
compensation from us, other than director and committee fees
and benefits under a tax-qualified retirement plan, or non-
discretionary compensation for prior service (provided such
compensation is not contingent in any way on continued
service), cannot be deemed independent. Compensation
received by a director for former service as an interim Chair or
Chief Executive Officer and compensation received by an
immediate family member for service as a non-executive
employee will not be considered in determining independence
under this test.
A director who (A) is, or whose immediate family member is,
a current partner of a firm that is our external auditor; (B) is a
current employee of such a firm; or (C) was, or whose
immediate family member was, within the last three years (but
is no longer) a partner or employee of such a firm and
personally worked on our audit within that time cannot be
deemed independent.
A director who is, or whose immediate family member is, or
has been within the last three years, employed as an executive
officer of another company where any of our present Named
Executive Officers at the time serves or has served on that
company’s compensation committee cannot be deemed
independent.
A director who is a current employee or general partner, or
whose immediate family member is a current executive officer
or general partner, of an entity that has made payments to, or
received payments from us for property or services in an
amount which, in any of the last three fiscal years, exceeds the
greater of $200,000 or 5% of such other entity’s consolidated
gross revenues, other than payments arising solely from
investments in AAON’s securities or payments under non-
discretionary charitable contribution matching programs,
cannot be deemed independent.
For purposes of the independence standards set forth
above, the terms:
“Affiliate” means any consolidated subsidiary of AAON and
any other company or entity that controls, is controlled by or is
under common control with AAON;
“Executive officer” means an “officer” within the meaning of
Rule 16a-1(f) under the Exchange Act, as amended; and
12
GOVERNANCE OF THE COMPANY
“Immediate family” means spouse, parents, children, siblings,
mothers- and fathers-in-law, sons- and daughters-in-law,
brothers- and sisters-in-law and anyone (other than
employees) sharing a person’s home, but excluding any
person who is no longer an immediate family member as a
result of legal separation or divorce, death or incapacitation.
In addition to the director independence standards set forth
above, the Board also requires the Chairs and all other
committee members to satisfy the heightened independence
standards set forth under applicable NASDAQ and SEC rules
for committee memberships. In connection with its assessment
of the independence of the directors, as set forth above, the
Board also determined that our Audit Committee Chair and all
other Audit Committee members meet the additional
independence standards of NASDAQ and the SEC applicable
to members of the Audit Committee.
The Board undertakes an annual review of the independence
of all non-employee directors. In advance of the meeting at
which this review occurs, each non-employee director is asked
to provide the Board with full information regarding the
director’s business and other relationships with us and our
affiliates and with senior management and their affiliates to
enable the Board to evaluate the director’s independence.
Directors have an affirmative obligation to inform the Board of
any material changes in their circumstances or relationships
that may impact their designation by the Board as
“independent”. This obligation includes all business
relationships between, on the one hand, directors or members
of their immediate family, and, on the other hand, AAON and
our affiliates or members of senior management and their
affiliates, whether or not such business relationships are
subject to any other approval requirements by us.
Policy Against Hedging or Pledging Stock
Our Insider Trading Policy prohibits our directors, officers and other employees, and their designees, from engaging in short sales or
from hedging transactions of any nature that are designed to hedge or offset a decrease in market value of such person’s ownership
of the Company's equity securities. Our Insider Trading Policy also prohibits our directors, officers and other employees, and their
designees, from purchasing financial instruments or engaging in other problematic transactions involving the Company’s equity
securities, including, puts, calls, collars, forward contracts or other derivative securities concerning the Company's equity securities.
We prohibit such conduct since purchasing such financial instruments or engaging in such transactions would result in the individual
no longer being exposed to the full risks of ownership of the Company’s equity securities, which may weaken the alignment of such
individual with the objectives of the Company’s stockholders. Additionally, our directors, officers and other employees may not pledge
or hold their Company equity securities in a margin account.
Board Leadership Structure
During 2024, our Board was led by A.H. "Chip" McElroy II, who was both the Independent Chair of the Board and Chair of the
Governance Committee and Caron A. Lawhorn, who was both our Independent Vice-Chair of the Board and Chair of the Audit
Committee. In addition, our Compensation Committee is also led by an independent director, Angela E. Kouplen.
The business of AAON is managed under the direction of our Board. In accordance with our Bylaws, we have an Independent Chair
of the Board, who presides at all meetings of the Board and stockholders. Our Board has also chosen to elect an Independent Vice
Chair of the Board to perform the duties and responsibilities as the Board may determine.
The Board has determined that our current Board structure, having the Independent Chair of the Board serve as the presiding officer
at all Board and stockholder meetings, and having an Independent Vice Chair, is currently the most appropriate leadership structure
for the Company and its stockholders. This fosters clear accountability, effective decision-making, alignment with corporate strategy,
direct oversight of management, full engagement of the remaining directors and continuity of leadership. Having an Independent
Chair and Independent Vice Chair demonstrates the Board's recognition of the importance of independent leadership and identifies
the individuals, elected by and from the independent directors, selected to act as the leaders of the independent directors and help
ensure appropriate discussions take place, in an open and forthright manner, at the Board level. The Board considers and reviews its
leadership structure annually by the independent directors in connection with its self-evaluation process. The Board believes its
current leadership structure is reasonable, appropriate and in the best interests of the Company and its stockholders.

GOVERNANCE OF THE COMPANY
Succession Planning
A key responsibility of the CEO and the Board is ensuring that an effective process is in place to provide continuity of leadership over
the long term at all levels in our Company. Each year, succession-planning reviews are held at every significant organizational level
of the Company, culminating in a full review of senior leadership talent by our independent directors. During this review, the CEO, the
Chair of the Board and the independent directors discuss future candidates for senior leadership positions, including all NEOs,
succession timing for those positions and development plans for the highest-potential candidates. This process ensures continuity of
leadership over the long term and it forms the basis on which our Company makes ongoing leadership assignments. It is a key
success factor in managing the long-term planning and investment lead times of our business.
Our Board and Corporate Strategy
Our Board is actively involved in overseeing, reviewing and guiding our corporate strategy. Our Board formally reviews our
Company's business strategy, including the risks and opportunities facing our Company and its business, at an annual strategic
planning session. Our Board regularly discusses corporate strategy throughout the year with management formally, as well as
informally, and during executive session of the Board as appropriate. As discussed in the "Risk Oversight" section below, our Board
views risk management and oversight as an integral part of our strategic planning process, including mapping key risks to our
corporate strategy and seeking to manage and mitigate risk. Our Board also views its own composition as a critical component to
effective strategic oversight. Accordingly, our Board and relevant Board committees consider our business strategy and the
Company's regulatory, geographic and market environments when assessing board composition, director succession, executive
compensation and other matters of importance.
Stockholder Engagement
Our Board of Directors and management team are committed to a comprehensive investor relations program. We believe regular
engagement with current and prospective stockholders to better understand their perspectives is integral to effective corporate
governance. The feedback we receive also helps align our strategy with stockholder expectations. To achieve the maximum output
from our outreach program, we utilize various methods including targeting, surveillance, investor perception studies, investor
conferences, investor day events, videoconferences and teleconferences. Our engagement program regularly includes our CEO,
COO, CFO and other members of our executive leadership team.
Who We Engage

•Institutional Investors | •Sell-Side Analysts | •Proxy Advisory Firms
•Retail Stockholders | •Pension Funds | •ESG Raters

How We Engaged In 2024
In 2024, members of our executive management team participated in six investor conferences, over a hundred investor conference
calls and various onsite meetings, amounting to approximately 130 investor engagements. Through these outreach efforts, our
executive management interacted with 95% of our top 20 institutional active investors and over 40% of AAON’s top 100 institutional
active investors.
Other ways of engagement in 2024 included quarterly earnings conference calls in which our executive management team responds
to analysts’ questions pertaining to recent results and the outlook to the business. On the Investor Relations page of our company
website, we regularly provide additional information in the form of Investor Relations presentations, earnings releases and
accompanying presentations, annual reports, annual Sustainability reports, as well as other financial and operational information. In
2024, we also engaged Rivel, Inc. to conduct an Investor Perception Study to gain feedback from current stockholders, prospective
investors and sell-side analysts on what management and the Board can do differently to help create value.

Integrating Feedback
The Board and management are receptive to feedback that results from our engagement with investors and integrate it into their
discussions and decision-making, as appropriate. Our dialogue in recent years has led to, among other things:
•Reinforcement and refinement of certain strategies.
•Improved qualitative and quantitative guidance to assist investors in better understanding management’s near-term and
long-term financial outlook.
•Major enhancements in our reporting, as demonstrated in our last four annual Sustainability reports.
•Capital distribution approach.
Risk Oversight
The Board has ultimate responsibility for oversight of our risk management processes. The Board discharges this oversight
responsibility through regular reports received from and discussions with senior management on areas of material risk exposure to
the Company. These reports and Board discussions include, among other things, operational, financial, legal, regulatory and strategic
risks. Additionally, our risk management processes are intended to identify, manage and control risks so that they are appropriate
considering our size, operations and business objectives. The full Board (or the appropriate committee in the case of risks in areas for
which responsibility has been delegated to a particular committee) engages with the appropriate members of senior management to
enable its members to understand and provide input to and oversight of our risk identification, risk management and risk mitigation
strategies. In addition, each of our Board committees considers the risks within its areas of responsibility. For example, the Audit
Committee reviews risks related to financial reporting; discusses material violations, if any, of Company governance, ethics and
compliance policies brought to its attention; considers the Company’s risk assessment that is part of the Company's strategic
planning which identifies control risks and drives the internal audit plan for the ensuing year; reviews the external audit plan; and
considers the impact of risk on our financial position and the adequacy of our risk-related internal controls. The Compensation
Committee reviews compensation and human resource risks. This enables the Board to coordinate risk oversight, particularly with
respect to interrelated or cumulative risks that may involve multiple areas for which more than one committee has responsibility. The
Board or applicable committee also has authority to engage external advisors as necessary.
Actions taken by the Board outside of Board meetings are consented to in writing by a memorandum of action in lieu of a meeting, to
which all incumbent directors subscribe. Directors meet their responsibilities not only by attending Board and committee meetings but
also through communication with members of management on matters affecting us.
Board Committee Structure
Currently, the Board has a standing Audit Committee, Compensation Committee and Governance Committee to assist the Board in
carrying out its functions. The Board has determined that each of the Chairs, as well as all committee members, are independent
under applicable NASDAQ and SEC rules for committee memberships. The members of the committees are shown in the table
below, followed by a brief description of each committee.

Our Board has adopted written charters for each of its Audit, Compensation and Governance Committees. Copies of the charters of
each of these committees are available on and may be printed from our website at www.aaon.com. Copies are also available from
our corporate secretary upon request.
Audit Committee
The Audit Committee assists the Board in fulfilling its responsibility for oversight of the quality and integrity of our accounting, auditing
and financial reporting practices. Among other things, the Audit Committee is responsible for: selecting and retaining our independent
public accountants; preapproving the engagement of the independent accountants for all audit and audit-related services and
permissible, non-audit-related services; reviewing in advance the scope and focus of the annual audit; and reviewing and discussing
with management and the auditors our financial reports, the audited financial statements, the auditor's report, the management letter
and the quality and adequacy of our internal controls. In addition, the Audit Committee is responsible for oversight and review of the
activities of the Company's internal audit function. The Board has determined that the Chair and the other Audit Committee members
are independent under applicable NASDAQ and SEC rules for Audit Committee memberships. The Audit Committee is governed by a
written charter, a copy of which is available on our website, at www.aaon.com.
The Board has determined that Ms. Lawhorn qualifies as an “audit committee financial expert” as defined by applicable SEC rules
and that each member of the Audit Committee meets the additional criteria for independence of audit committee members set forth in
Rule 10A-3(b)(1) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and Section 5605(c) of the NASDAQ
Stock Market Listing Standards.
Compensation Committee
The responsibilities of the Compensation Committee, as set forth in its charter, include the direct responsibility and authority to review
and approve our goals and objectives relevant to the compensation of our Chief Executive Officer and other executive officers, to
evaluate the performance of such officers in accordance with the policies and principles established by the Compensation Committee
and to determine and approve, either as a Committee, or (as directed by the Board) with the other “independent” Board members (as
defined by the NASDAQ listing standards), the compensation level of the Chief Executive Officer and the other executive officers. The
Compensation Committee is composed of the three independent (non-employee) directors, named in the table above, each of whom
is “independent” as defined by applicable NASDAQ and SEC rules for committee memberships. The Compensation Committee is
governed by a written charter, a copy of which is available on our website, at www.aaon.com. In accordance with its charter, our
Compensation Committee has the sole authority to retain and terminate its compensation consultant and to review its compensation
consultant's independence on an annual basis.
Governance Committee
The responsibilities of the Governance Committee include proposing to the Board a slate of nominees for election by the stockholders
at the Annual Meeting and maintaining a list of prospective director candidates in the event of the resignation, death, removal or
retirement of directors or a change in the Board composition requirements. The Committee is also charged with reviewing with the
Board the desired experience, mix of skills and other qualities to assure appropriate Board composition. The Board has determined
that the Chair and all Governance Committee members are independent under applicable NASDAQ and SEC rules for committee
memberships.
16
GOVERNANCE OF THE COMPANY
The responsibilities of the Governance Committee also include the periodic reviews and monitoring of the Company’s corporate
governance guidelines (including the Company’s Code of Conduct), recent developments in corporate governance concepts, the
Company’s plans for CEO and senior management succession, regulatory requirements relevant to the Company’s corporate
governance guidelines to assure the Company’s compliance therewith, and the Company’s Articles of Incorporation and Bylaws.
The Board has determined that the Chair and all Governance Committee members are independent under applicable NASDAQ and
SEC rules for committee memberships.
Director Nominations
Our Bylaws also provide that a stockholder may nominate a director for election at an annual meeting if written notice is given to us
not less than 90 and not more than 120 days in advance of the anniversary date of the immediately preceding annual meeting.
If and when new vacancies occur in the future, the Board will consider director nominees recommended by stockholders, in
accordance with our Bylaws. The Board does not have a formal policy regarding the consideration of, procedures to be followed by,
minimum qualifications of or process for identifying or evaluating nominees recommended by stockholders.
Among the criteria developed by the Governance Committee for qualification for director nominees as well as director retention, a
candidate must have demonstrated accomplishment in his or her chosen field, character and personal integrity, and the ability to
devote sufficient time to carry out the duties of a director. The Governance Committee considers whether the candidate is
independent under the standards described below under “Director Independence.” In addition, the Governance Committee considers
all information relevant in their business judgment to the decision of whether to nominate a particular candidate, taking into account
the then-current composition of the Board and assessment of the Board’s collective requirements. These factors may include: a
candidate’s age, professional and educational background, reputation, industry knowledge and business experience and relevance to
the Company and the Board (including the candidate’s understanding of markets, technologies, financial matters and international
operations); whether the candidate will complement or contribute to the mix of talents, skills and other characteristics that are needed
to maintain the Board’s effectiveness; and the candidate’s ability to fulfill responsibilities as a director and as a member of one or
more of our standing Board committees. Although the Board does not have a formal diversity policy for Board membership, the
Governance Committee considers whether a director nominee contributes or will contribute to the Board in a way that can enhance
the perspective and experience of the Board through diversity in gender, ethnicity, geography and professional experience.
Nomination of a candidate is not based solely on the factors noted above. When current Board members are considered for
nomination for re-election, the Governance Committee also takes into consideration their prior Board contributions, performance and
meeting attendance records. The Governance Committee does not assign specific weights to particular criteria, and no particular
criterion is a prerequisite for Board membership. We believe that the backgrounds and qualifications of our directors, considered as a
group, provide an appropriate mix of experience, knowledge and abilities to allow the Board to fulfill its responsibilities. The
effectiveness of the Board’s skills, expertise and background is also considered as part of each Board and committee's annual self-
assessment evaluation process conducted at the direction of the Governance Committee.
Director Compensation
As outlined in its charter, the Compensation Committee has the authority to review and make recommendations to the Board with
respect to the components and amount of Board compensation in relation to other similarly situated companies. Periodically, the
Committee directs its compensation consultant to provide an independent assessment of the Company's Board compensation
program. This review was last conducted in 2024. The Committee targets total Board compensation levels at a competitive range of
peer group total Board compensation. The Committee considers total aggregate Board compensation and other factors when making
recommendations to the Board for approval.

Company for the year ending December 31, 2025. The Board is submitting the selection of Grant Thornton LLP for ratification at the

Thornton, LLP as our independent auditor for the 2025 audit, the Committee discussed the services with management and Grant
Thornton, LLP, and subsequently approved GT as auditor. The audit services are comprised of work performed in the audit of our
financial statements and to attest and report on our internal controls over financial reporting, as well as work that only the
independent auditor can reasonably be expected to provide, including:
•Quarterly review of our unaudited financial statements;

following executive officers of the Company (collectively, the "named executive officers" or “NEOs”):

NEO Name | NEO Title
Gary D. Fields | Chief Executive Officer
Rebecca A. Thompson | Vice President, Finance, Chief Financial Officer and Treasurer
Matthew J. Tobolski | President, Chief Operating Officer
Stephen E. Wakefield(1) | Vice President, Executive Vice-President of AAON, Inc. (an Oklahoma Corporation)

Executive Summary
During 2024, our executive officers led our efforts to increase sales, executed our internal capital expenditure programs and
positioned the Company to capitalize on anticipated growth. Some of the key accomplishments during 2024 include:
Financial Performance
The Company ended the year with a backlog of $867.1 million, up 70.0% compared to December 31, 2023. The increase is the
result of the increased demand in the data center market. In the fourth quarter of 2024, the Company received over $200.0 million in
orders for the BASX branded data center liquid cooling solutions. The overwhelming demand for BASX branded products also
helped drive net sales growth of 2.7% to $1,200.6 million for the year ended December 31, 2024.
Expansion and Growth
We had record capital expenditures for the year ended December 31, 2004 of $195.7 million. These investments funded our
expansions across multiple facilities. We added 237,500 square feet to our Longview, Texas facility primarily for production of BASX
branded data center products. We also completed the addition of a new Weld Shop in Redmond, Oregon that created more capacity
in our manufacturing building. In Parkville, Missouri, we built an SMT production line to produce our own control boards. We have
also made investments to purchase and develop software for internal use in anticipation of future Company growth. In December
2024, the Company purchased a new 787,000-square-foot facility in Memphis, Tennessee, which will accommodate incremental
demand for both BASX and AAON products over the next several years, at the same time providing more geographic diversification
across our manufacturing footprint. The purchase price for the facility was approximately $63.4 million.
Total Shareholder Return (TSR)
The market price of our common stock was $117.68 per share on December 31, 2024, an increase of approximately 59.3% from the
closing price of $73.87 on December 29, 2023. We generated TSR of approximately 143.2% from January 1, 2022 through
December 31, 2024. This return exceeded the returns over the same period of 38 of 48 companies in the S&P 600 Capital Goods
Index.
Dividends and Stockholder Returns
We are committed to returning value to our stockholders. We make quarterly dividend payments with increases as needed. We want
to reward long-term stockholders through share buybacks. When we have excess cash, we work to repurchase shares and decrease
our share count. In 2024, we completed the repurchase of 1.4 million shares in the open market for $100.0 million at an average
price of $73.90.
31
COMPENSATION DISCUSSION AND ANALYSIS
Compensation Philosophy
The following outlines key features of our compensation program, in addition to typical "best practices" that we adhere to:

What We Do |  | What We Do Not Do
Pay for Performance: Our executive compensation plan is aligned with stockholder interests by rewarding for strong financial performance and stock price appreciation. |  | No Stock Option Re-Pricing: We do not permit re-pricing of equity awards without stockholder approval.
Stock Ownership /Retention Requirements: Our directors, executive officers and certain other key employees are subject to robust stock ownership and retention requirements. |  | No Tax Gross-Ups: We do not provide tax gross-ups.
Independent Compensation Consultant: We utilize an independent compensation consultant reporting directly to the Compensation Committee. |  | No Hedging or Pledging in Company Securities: Our directors, executive officers and other employees are prohibited from engaging in hedging transactions, short sales, pledging or derivative transactions with respect to AAON securities.
Limited Perquisites: We provide executive physicals for our NEOs, which aligns with our wellness initiatives and assists in mitigating risk. |  | No Employment Agreements: AAON does not have employment agreements with our NEOs.
Compensation Clawback: Our executive officers are subject to a compensation clawback policy (with a three-year look-back period) that requires reimbursement of any bonus or incentive compensation (as well as the cancellation of unvested, restricted or deferred equity awards) in the event of officer misconduct that was a material factor causing a restatement of the Company’s financial statements. We also maintain a compensation recovery (clawback) policy that complies with Nasdaq requirements. |  | We do not provide single-trigger for equity treatment upon a change in control.

Our executive compensation programs are determined and approved by our Compensation Committee, after consideration of
recommendations by the Principal Executive Officer ("PEO") (for individuals other than himself) and information provided by the
Compensation Committee's independent compensation consultant. The Compensation Committee, however, uses its own judgment
to ultimately make the final decisions concerning compensation paid to our NEOs.
The Compensation Committee has the direct responsibility and authority to review and approve our goals and objectives relative to
the compensation of the NEOs, and to determine and approve (either as a committee or with the other members of our Board who
qualify as “independent” directors under applicable guidelines adopted by NASDAQ) the compensation levels of the NEOs. However,
when making pay decisions for the NEOs, we consider input and recommendations from the Company's PEO (for individuals other
than himself). Equity awards are generally granted to our NEOs after filing of our annual report. In certain circumstances, including
the hiring or promotion of an officer, the Compensation Committee may approve grants to be effective at other times. The
Compensation Committee did not take material nonpublic information into account when determining the timing and terms of equity
awards in 2024, and the Company does not time the disclosure of material nonpublic information for the purpose of affecting the
value of executive compensation.
Our historical executive compensation programs have intended to achieve two objectives:
1.To enhance our profitability and stockholder value;
2.To attract, motivate, reward and retain high-quality employees, including executive personnel, who contribute to our long-
term success.
As described in more detail below, the material elements of our historical executive compensation program for NEOs include a base
salary, annual incentive bonuses, equity-based compensation and Company contributions to AAON’s 401(k) plan.
32
COMPENSATION DISCUSSION AND ANALYSIS
We believe that each element of the executive compensation program helps to achieve one or both of the compensation objectives
outlined above. The table below lists each material element of our executive compensation program and the compensation objective
or objectives that it is designed to achieve.

Compensation Element | Compensation Objectives
Base Salary | Attract and retain qualified executives;
Motivate and reward executives’ performance;
Stay competitive in the marketplace;
Bonus Compensation | Motivate and compensate executives’ performance;
Stay competitive in the marketplace;
Motivate the achievement of short-term business objectives that contribute to our long-term strategic direction;
Equity-Based Compensation — Performance share units, restricted stock awards, and stock options | Enhance profitability of AAON and stockholder value by aligning executives with stockholders’ interest;
Attract and retain qualified executives;
Motivate the successful execution of our long-term strategic objectives;
Retirement Benefits – 401(k) and Health | Attract and retain qualified executives;
Savings Account | Stay competitive in the marketplace;

Our executive compensation program is designed to reward performance for enhanced profitability, revenue growth and ultimately
increased stockholder value. We believe in a compensation plan that fosters a culture of ownership and stockholder alignment that
allows us to attract and retain top talent who are similarly focused on the creation of long-term value. We reward our executive
officers with a pay mix that emphasizes long-term compensation through performance share units, stock options and restricted stock
awards to align stockholders' and executives’ interests. We strive to provide total compensation that falls within a reasonable range of
our peer group market median for NEOs, which also considers individual attributes and performance, as well as company
performance. We utilize an annual bonus and equity program to incentivize executive officers to meet and exceed Company
performance goals. We maintain a compensation program that operates in the best interests of AAON and our stockholders,
rewarding NEOs based on performance.
Under the terms of the Compensation Committee Charter, the Compensation Committee is authorized to engage independent
advisors, at the Company's expense, to advise the Compensation Committee on any matters within the scope of the Committee's
duties. For 2024, the Compensation Committee retained Meridian Compensation Partners, LLC ("Meridian") to serve as an
independent consultant to the Committee to provide information and objective advice regarding executive and outside director
compensation. The Committee did not direct Meridian to perform its services in any particular manner or under any particular method.
The Committee has the final authority to hire and terminate the compensation consultant and the Committee evaluates the
compensation consultant annually. Meridian does not provide any services to the Company other than in its role as advisor to the
Committee and performing valuations of our PSUs, and the Committee has determined that no conflicts of interest exist as a result of
the engagement of Meridian.
Benchmarking and Peer Group
The Compensation Committee evaluates executive compensation by benchmarking our NEOs’ target total compensation relative to
comparable market data provided by our independent compensation consultant. Market references are provided for our NEOs, where
available, from our peer group which consists of 17 publicly-traded companies of similar size, operating in similar industries to AAON
(detailed below). This group is reviewed and approved annually, with modifications made as needed, considering changes to
business characteristics, size, M&A, etc. Where data may be limited for certain roles, or as an additional market reference, survey
data is also used and is reflective of manufacturing organizations with revenues within a reasonable range of AAON.
33
COMPENSATION DISCUSSION AND ANALYSIS
Each element of compensation is benchmarked against peer and/or survey-reported pay information, as applicable. Target total
compensation is generally targeted within a reasonable range of median; however, variation may exist based on individual and
company performance, tenure in role, future potential, and internal equity.
Peer Group Used for 2024 Pay Decisions:

Ameresco, Inc. | Gibraltar Industries, Inc. | The AZEK Company Inc.
Armstrong World Industries, Inc. | Insteel Industries, Inc. | The Gorman-Rupp Company
CECO Environmental Corp. | PGT Innovations, Inc. | Thermon Group Holdings, Inc.
CSW Industrials, Inc. | Powell Industries, Inc. | Trex Company, Inc.
Encore Wire Corporation | Quanex Building Products Corporation | Vicor Corporation
Enerpac Tool Group Corp. | Simpson Manufacturing Co., Inc. |

The Committee reviewed the above peer group and determined no changes were needed from the prior year. The group shown
above was considered when establishing 2024 pay levels.
2024 Executive Compensation Program Elements
The following discussion, as well as the information contained in the tables below, are based upon our historical and current
compensation plans, in effect in 2024 and in the previous reported year. In support of our pay-for-performance philosophy, a majority
of the target compensation for our NEOs under our annual compensation program is allocated to variable compensation, with the
structure for the CEO weighted even more heavily towards performance-based pay.
AAON's pay philosophy emphasizes risk and pay-for-performance with 82.1% of our CEO's target compensation at risk for 2023 and
66.5% of our other NEOs target compensation at risk.
34
COMPENSATION DISCUSSION AND ANALYSIS
Base Salaries
Below is a summary of 2024 annual base salaries for our NEOs:

Named Executive Officer | 2023 Base Salary | 2024 Base Salary | Percent Increase
Gary D. Fields | $750,000 | $800,000 | 6.7%
Rebecca A. Thompson | $375,000 | $410,000 | 9.3%
Matthew J. Tobolski (1) | $— | $500,000 |
Stephen E. Wakefield | $330,000 | $400,000 | 21.2%
David E. Benson (2) | $— | $400,000 |
(1) Mr. Tobolski was hired as President and Co-Founder of BASX, Inc. effective December 10, 2021. He was promoted to President and Chief Operating Officer of the Company, effective January 1, 2024.
(2) Mr. Benson was hired as Chairman and Co-Founder of BASX, Inc. effective December 10, 2021. He was promoted to Vice President of the Company and President of BASX, Inc. effective January 1, 2024.

In approving these executives’ salary levels, the Committee took into account certain factors, including, recommendations of the
principal executive officer (except as it related to himself), each executive's individual experience and responsibilities, and the
Company’s performance. Further, as shown in the comprehensive benchmarking study conducted by the independent compensation
consultant, base salary levels for each of our NEOs were positioned below the median of the applicable market benchmark. Base
salary increases were based on individual and Company performance, market data (market adjustments made with the intention of
more closely aligning with market median, over time) and other internal considerations.
Effective January 1, 2024, Mr. Wakefield was promoted to Vice President of AAON and Executive Vice-President of AAON, Inc. (an
Oklahoma Corporation). The adjustment in base salary for Mr. Wakefield reflects his responsibility for overseeing the Company's
largest segment which includes the engineering teams for our traditional rooftop and controls products that has driven much of the
Company's value through the years. His leadership has also been key to maintaining our culture of innovation and entrepreneurial
spirit.
Annual Cash Incentive Bonuses
We have an “at risk” annual incentive bonus which is intended to facilitate alignment of management with corporate objectives and
stockholder interests in order to achieve outstanding performance and to meet specific financial goals by:
•providing the employees designated by the Committee, incentive compensation tied to stockholder interests and goals for
the Company;
•providing competitive compensation to attract, motivate, reward and retain employees who achieve outstanding
performance;
•fostering accountability and teamwork throughout the Company; and
•contributing to the long-term success of the Company.
We believe the annual incentive bonus should be a substantial component of total compensation and based upon achievement of the
Company’s annual "Opportunity Budget" and is weighted on the following two components which drive stockholder value:
1.Operating Profit (67%) - The Company's Operating Profit calculated as the Company's budgeted net income before “profit
sharing” and income taxes, but after bonus accrual; and
2.Net Sales (33%) - The Company’s budgeted net sales.
The annual incentive compensation opportunity is expressed as a percentage of the executive officer’s base salary multiplied by a
bonus factor. Bonus factors for each Named Executive Officer are as follows:
35
COMPENSATION DISCUSSION AND ANALYSIS

Named Executive Officer | 2023 Bonus Target | 2024 Bonus Target
Gary D. Fields | 100% | 105%
Rebecca A. Thompson | 65% | 65%
Matthew J. Tobolski | —% | 70%
Stephen E. Wakefield | 65% | 65%

AAON’s annual incentive program also consists of an individual performance assessment which allows the Committee to recommend
to the Board that any earned annual incentive payout be adjusted +/-15% based on the Committee’s assessment of individual
performance against his or her annual objectives. A sample of these objectives for our CEO include:
•Leadership and development of high-performing team
•Overall company financial and operational performance
•Optimizing operational efficiency
Performance assessments are reviewed for all NEOs by the Compensation Committee. The Compensation Committee will
recommend to the Board in the case of Mr. Fields and Mr. Fields will recommend to the Compensation Committee in the case of other
NEOs a performance adjustment to increase or decrease the bonus amount earned by each NEO up to 15% based upon how such

COMPENSATION DISCUSSION AND ANALYSIS
individual has performed in relation to his or her annual objectives. For 2024, no adjustments were applied for individual
performance.
Equity-Based Compensation
Our policy is that the NEOs’ long-term compensation should be directly linked to enhancing profitability and value provided to our
stockholders. Accordingly, the Compensation Committee grants equity awards under our 2016 and 2024 Long-Term Incentive Plan,
creating a strong linkage between realized pay to stockholder value creation. Such grants are largely based upon the
recommendation of the principal executive officer (except as to himself) based on the NEO's performance in the prior year and his or
her expected future contribution to our performance.
Positive overall Company performance (financial as well as stock price performance) is a primary element associated with the grant
of equity-based compensation to the executive officers as a group. When determining the total value of compensation provided to our
executive officers, our Compensation Committee, with the advice of our CEO, evaluates various aspects of Company performance in
light of general economic conditions, and compares the Company's performance against similar competitors in the industry.
Performance elements considered may include improvement in sales performance, cost containment initiatives, product and
marketing development, risk management, or successful completion of major capital projects, including enhancements to
manufacturing operations. These elements have not been specifically weighted in determining the amount of the equity incentive
awards because the relative importance of each element may change from time to time and the responsibilities of each executive
officer, as they contribute to the achievement of any particular objective, may vary.
Factors considered when determining any specific equity-based award include:
•the responsibilities of the executive officer;
•the scope, level of expertise and experience required for the executive officer’s position and the period during which the
officer has performed these responsibilities;
•the strategic impact of the officer’s position; and
•the potential future contribution of the officer.
In 2024, we maintained the same targeted equity mix used the previous year, which emphasizes performance-based elements of
PSUs (50%) and stock options (25%), with the remaining 25% allocated to restricted stock awards. The PSUs will measure AAON’s
three-year total shareholder return ("TSR") relative to the constituents of the S&P 600 SmallCap Capital Goods Industry Group (as
constituted at the beginning of the performance period). This allows us to reward executives for performance relative to companies
facing similar market forces and aligns the interests of management with stockholders by incentivizing performance that drives
returns that exceed our peers. The vesting horizon for the time-vested restricted shares and stock options is three years to align with
the three-year performance period/vesting horizon of the PSUs. Please see the exhibit below for the relative TSR performance and
payout scale:

TSR Percentile Ranking | Payout as a % of Target
80th Percentile or Above | 200%
55th Percentile | 100%
30th Percentile | 50%
Below 30th Percentile | 0%

Results between points are interpolated on a straight-line basis. In the event that AAON's absolute TSR is negative over the three-
year performance period, the payout will be capped at 100.0% of target, regardless of relative performance.
F or the three-year performance period of January 1, 2022 through December 31, 2024, the Company's TSR was 143.2% which
ranked in the 79.1th percentile of our peer group and resulted in a final payout of 196.4% of target. The resulting shares can be
found in the Performance Unit Vesting Schedule shown as part of the Grants of Plan-Based Awards tables.
37
COMPENSATION DISCUSSION AND ANALYSIS
Awards may be granted to new key employees on their hire date. Other grant date determinations are made by the Compensation
Committee, which are based upon the date the Committee met and proper communication was made to the NEO or key employee as
defined in the definition of grant date by FASB ASC Topic 718. Stock option exercise prices are equal to the value of AAON stock on
the close of business on the determined grant date. We have no program or practice to coordinate timing of grants with release of
material, nonpublic information.
Retirement Benefits - Defined Contribution Plan, 401(k) and Health Savings Account
We sponsor a defined contribution plan (the "Plan”). Eligible employees may make contributions in accordance with the Plan and IRS
guidelines. In addition to the traditional 401(k), eligible employees are given the option of making an after-tax contribution to a Roth
401(k) or a combination of both. Eligible employees are automatically enrolled in the Plan at a 6.0% deferral rate and currently
contributing employees' deferral rates are increased to 6.0% each year, unless their current rate is above 6.0% or the employee
elects to decline the automatic enrollment or increase.
The Company presently matches 175% up to 6.0% of employee contributions of eligible compensation. Administrative expenses for
the Plan are paid for by Plan participants. Additionally, Plan participant forfeitures are used to reduce the cost of the Company
contributions. We contribute in the form of cash and direct the investment to shares of AAON stock. Employees are 100.0% vested in
salary deferral contributions and vest 20.0% per year at the end of years two through six of employment in employer matching
contributions.
The amounts contributed by us to each NEO under the 401(k) plan are based on actual contributions and the base salary, bonus and
equity compensation of the employee, and are reported in the “All Other Compensation” column of the “Summary Compensation
Table” for each NEO, if applicable, and if the threshold reporting requirements were met. Our employees participate in a high-
deductible health savings plan wherein they may open a Health Savings Account. We match 175.0% of employee contributions to
their Health Savings Account.
Other Compensation Program Components
In addition to establishing the pay elements described above, we have adopted a number of policies to further the goals of the
executive compensation program, particularly with respect to strengthening the alignment of our NEOs’ interests with stockholder
long-term interests.
Termination and Severance Arrangements
The Executive Severance Plan includes senior executive officers, which includes NEOs, in order to define a consistent approach of
treatment in the event of a severance event. Under the plan, NEOs are eligible to receive a payment of 1.5 to 2.0 times the sum of
the NEOs base salary and, in certain circumstances, target annual bonus. Any severance payment is subject to the execution of an
irrevocable release of claims.
Change in Control Agreements
Our change in control agreements, in conjunction with the NEOs’ equity award agreements, provide separation benefits for our
NEOs. Our program includes a double trigger for benefits and equity vesting. This means there must be a Company change in control
and the NEO must experience a qualifying termination of employment prior to receiving benefits under the agreement. This practice
creates security for the NEOs but does not provide an incentive for the NEO to leave the Company. Our program is designed to
encourage the NEOs to focus on the best interests of stockholders by alleviating their concerns about a possible detrimental impact
to their compensation and benefits under a potential change in control, not to provide compensation advantages to NEOs for
executing a transaction.
Our Committee reviews our change in control benefits periodically to ensure they are consistent with competitive practice and aligned
with our compensation philosophy. As part of the review, calculations are performed to determine the overall program cost to the
Company if a change in control event were to occur and all covered NEOs were terminated as a result. An assessment of competitive
norms, including the reasonableness of the elements of compensation received, is used to validate benefit levels for a change in
control. The Committee continues to believe that offering a change in control program is appropriate and critical to attracting and
retaining executive talent and keeping them aligned with stockholder interests in the event of a change in control.
38
COMPENSATION DISCUSSION AND ANALYSIS
Stock Ownership and Retention Policy
The Board approved robust stock ownership and retention policies for directors and executive officers in order to further align the
interests of our directors and executive officers with those of our stockholders. Our stock ownership and retention policy is as follows:
Amount of Ownership: determined as a multiple of the individual’s base salary or a specified dollar value, as noted below. These
amounts represent the minimum amount of AAON stock an individual should seek to acquire and maintain:

Position | Minimum Stock Ownership Requirements
CEO | 6 times base salary
President (when separate from CEO) | 4 times base salary
CFO, COO, EVP, SVP | 3 times base salary
Other Officers | 2 times base salary
Directors | 6 times board level cash retainer

Eligible Forms of Equity to Determine Value:
•Shares owned individually or jointly with the individual's spouse and/or children residing in the same household
•Shares held in a trust for the benefit of the Subject Person, as well as for the benefit of his or her family
•Shares owned and held within the Company's 401(k) plan
•Unvested restricted stock awards.
Retention Requirements for Equity Awards:
•In the event a Subject Person is not meeting the Minimum Stock Ownership requirements, the Subject Person must retain
75.0% of shares, net of taxes, of each award as it vests and each stock option as it is exercised.
As of March 14, 2025, all current non-employee directors satisfy the ownership requirement. Since Mr. Fields is an executive officer
of the Company (in addition to being a director), he must comply with the equity ownership guidelines applicable to his respective
officer position. As of March 14, 2025, all NEOs satisfy the minimum ownership requirements.
Prohibition on Hedging or Pledging Stock
Our Insider Trading Policy prohibits our directors, NEOs and all other insiders (including each of their designees) from engaging in
short sales or from hedging transactions of any nature that are designed to hedge or offset a decrease in market value of such
person’s ownership of the Company's equity securities. Our Insider Trading Policy also prohibits our directors, NEOs and all other
insiders (including each of their designees) from purchasing financial instruments or engaging in other problematic transactions
involving the Company’s equity securities, including, puts, calls, collars, forward contracts or other derivative securities concerning
the Company's equity securities. We prohibit such conduct since purchasing such financial instruments or engaging in such
transactions would result in our insiders no longer being exposed to the full risks of ownership of the Company’s equity securities,
which may weaken the alignment of our insiders with the objectives of the Company’s stockholders. Additionally, our directors, NEOs
and all other insiders may not pledge or hold their Company equity securities in a margin account.
Clawback Policies
Our Company has a Compensation Adjustment and Recovery Policy for our NEOs. Pursuant to this policy (commonly referred to as a
clawback policy), our NEOs are subject to a compensation clawback (with a three-year look-back period) that requires reimbursement
of any bonus or incentive compensation (as well as the cancellation of unvested, restricted or deferred equity awards) in the event of
officer misconduct that was a material factor causing a restatement of the Company’s financial statements.
39
COMPENSATION DISCUSSION AND ANALYSIS
In addition, effective October 2, 2023, the Board approved a new Executive Officer Compensation Recovery Policy (the "Mandatory
Clawback Policy"), that is designed to comply with, and will be interpreted pursuant to, Section 10D of the Exchange Act and the
applicable rules of Nasdaq. Under the Mandatory Clawback Policy, in the event of an accounting restatement due to the Company's
material noncompliance with any financial reporting requirement under applicable securities laws, including required accounting
restatements to correct a material error in previously issued financial statements, or that would result in a material misstatement if the
error were corrected in the current period or left uncorrected in the current period, the Company must recover erroneously awarded
performance-based compensation previously paid to the Company's executive officers pursuant to the terms of the Mandatory
Clawback Policy. The Company is prohibited from indemnifying any executive officer (current or former) against the loss of
erroneously awarded performance-based compensation and from paying or reimbursing any executive officer for the cost of
insurance to cover any such loss.

Narrative Disclosure to Summary Compensation Table and Grants of Plan-Based Awards Table
A discussion of 2024 salaries, bonuses and long-term incentive awards is included in “Executive Compensation”.
NEOs are not separately entitled to receive dividend equivalent rights with respect to each stock option; however, dividends are paid
for restricted stock awards (retroactively upon vesting). Each non-qualified stock option award described in the “Grants of Plan-Based
Awards Table” above expires on the tenth anniversary of its associated grant date and vests in equal installments over three years.
43
COMPENSATION OF NAMED EXECUTIVE OFFICERS
Restricted stock awards vest in equal installments over the course of three years. Restricted stock awards granted to Gary D. Fields
vest over a three, two or one-year period (in the case of awards relating to his service as a director). In the case of awards relating to
his service as an officer restricted stock awards vested over three years.
The PSUs vest based on the level of achievement with respect to the Company's TSR benchmarked against similar companies
included in the capital goods sector of the S&P SmallCap 600 Index. The TSR measurement period is three years. At the end of the
measurement period, each award will be converted into AAON common stock at 0% to 200% of the PSU held.

CEO Pay Ratio
As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(u) of Regulation S-
K, we are providing the following information concerning the relationship of the annual total compensation of our employees and the
annual total compensation of Mr. Gary D. Fields, our CEO. For 2024, our last completed fiscal year:
•the median of the annual total compensation of all employees of our Company (excluding our CEO) was $61,661; and
•the annual total compensation of our CEO, as reported in the Summary Compensation Table included in this Proxy
Statement, was $4,148,634.
Based on this information, the ratio of the annual total compensation of our CEO to the median of the annual total compensation to all
other employees for 2024 was 67.3 to 1.
To identify the median of the annual total compensation of all our employees, as well as to determine the annual total compensation
of our median employee and our CEO, we took the following steps:
1.We determined that, as of December 31, 2024, our employee population consisted of approximately 4,653 individuals with
all of these individuals located within the United States (as reported in Item 1, Business, in our Annual Report on Form 10-K
filed with the Securities and Exchange Commission on February 27, 2025 (our “Annual Report”)). This population consisted
of our full-time, part-time and temporary employees.
a.We used December 31, 2024 for our determination date for ease of reconciling data back to tax and payroll
records.
46
COMPENSATION OF NAMED EXECUTIVE OFFICERS
2.To identify the “median employee” from our employee population, we compared the amount of salary, wages, 401(k)
contributions and HSA contributions as reflected in our payroll records as reported to the Internal Revenue Service on Form
W-2 for 2024.
a.Based on our particular facts and circumstances, we determined annualizing the total compensation of our
permanent partial-year employees would not reasonably reflect the annual compensation of our employee
population. As a result, we did not annualize the total compensation of our permanent employees who worked less
than all of 2024 and therefore excluded such partial-year employees from the employee population utilized in our
calculations.
Since we historically widely distribute annual equity awards to all levels of our employees, such awards were included in our
compensation measure.
1.We identified our median employee using this compensation measure, which was consistently applied to all of our
employees included in the calculation. Since all of our employees (including our CEO) are located in the United States, we
did not make any cost-of-living adjustments in identifying the median employee.
2.After identifying our median employee, we combined all of the elements of such employee’s compensation for 2024 in
accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K, which resulted in annual total compensation of
$61,661. The difference between such employee’s wages and the employee’s annual total compensation represents the
estimated value of such employee’s 401(k) matching contributions, HSA matching contributions, and equity awards.
For the annual total compensation of our PEO, we use the amount reported in the “Total” column of our 2024 Summary
Compensation Table included in this Proxy Statement and incorporated by reference under Item 11 of Part III of our Annual Report.
Pay Versus Performance
The following table sets forth information concerning the compensation of our PEO and other NEOs for each of the fiscal years ended
December 31, 2024, 2023, 2022, 2021 and 2020 and our financial performance for each such fiscal year. The table includes a
calculated value titled "compensation actually paid" ("CAP"), the majority of which has in fact not been earned or paid and reflects
updated values of outstanding equity awards that are still subject to vesting, and in some cases, performance requirements.

All fair value calculations were performed in accordance with the provisions of FASB ASC Topic 718 and consistent with the methods
utilized to calculate grant date fair values as disclosed in Note 15 - Share-Based Compensation to our consolidated financial
statements in our Annual Report on Form 10-K for the year ended December 31, 2024. Non-qualified stock option fair values are
calculated based on the Black-Scholes option pricing model. Adjustments have been made using our stock price as of each
measurement date and updated assumptions for expected term, volatility, dividend yield and interest rates. Restricted stock award
adjustments have been made using our stock price as of each measurement date and updated assumptions for interest rates and
dividend yield and accrued dividends for vesting restricted stock awards. For PSUs, adjustments at each measurement date have
been made based on the expected level of achievement with respect to the Company's TSR benchmarked against the S&P 600
Capital Goods Industry Group.
Narrative to Pay Versus Performance Table
For the year ending December 31, 2024, the most important financial performance measures used to link compensation actually paid
to our NEOs to Company performance were net sales, operating profit and our TSR. Our NEO's target total compensation is tied to
performance goals aligned with our stockholders' interest. The majority of target compensation was weighted toward long-term equity
performance and time-based awards and the financial performance metric was TSR. The short-term incentive program's funding
metrics are net sales and operating profit.
The graphs below depict the relationship between compensation actually paid and the Company's cumulative total shareholder
return, net income, net sales and operati ng profit:

Proposal No. 3 - Advisory Vote on Executive Compensation
Our Board is asking our stockholders to vote, on an advisory basis, to approve the compensation of our NEOs, as disclosed in this
Proxy Statement in accordance with SEC rules and Section 14A of the Exchange Act. We recognize the interest our stockholders
have in the compensation of our executives and this proposal gives us the opportunity to obtain the views of stockholders on the
effectiveness of our executive compensation program. This vote is not intended to address any specific item of compensation, but
rather concerns the overall compensation of our NEOs, and the policies and practices described in this Proxy Statement. Because
this vote is advisory, it is therefore not binding on the Company. However, the Board and the Compensation Committee value the
opinions of our stockholders and will consider our stockholders’ views, including what, if any, actions may be appropriate to address
any concerns identified through the advisory vote.
Say-On-Pay
At the Company’s 2022, 2023 and 2024 annual meetings of stockholders, approximately, 95.0%, 93.6% and 96.8%, respectively, of
the votes cast, supported the Company’s say-on-pay proposal. As noted above, our Board has decided to conduct say-on-pay votes
every year following our 2020 Annual Meeting so that our stockholders may express their views on our executive compensation
program on an annual basis.
In accordance with the requirements of Section 14A of the Exchange Act and the related rules of the SEC, the Board recommends
that the stockholders approve the following resolution at the Annual Meeting:
“RESOLVED, that the Company’s stockholders approve, on an advisory basis, the compensation of the named executive officers, as
disclosed in the Company’s Proxy Statement for the 2025 Annual Meeting of Stockholders pursuant to the compensation disclosure
rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis, the Summary
Compensation Table and the other related tables and disclosures.”
Vote Required
Approval of Proposal No. 3 will require the affirmative vote of a majority of the votes cast on the proposal. Accordingly, abstentions
and broker non-votes will have no effect on the outcome of the vote on this proposal.
Recommendation of the Board:
The Board unanimously recommends that stockholders vote FOR Proposal No. 3.
