### Executive Compensation Highlights and Pay-for-Performance Alignment
Our executive compensation program is designed by our compensation committee to (i) align executive compensation with our financial and operational performance; (ii) attract, retain and motivate key executives critical to achieving our vision and strategy; and (iii) reward such executives for delivering desired business results and stockholder value, all while protecting against excessive risk taking. Our executive compensation program is described in more detail in the Compensation Discussion and Analysis section beginning on page 35 of this proxy statement. The following table summarizes our key executive compensation practices:

---

| | |
|:---|:---|
|  **✓ WHAT WE DO** | **✘ WHAT WE DON'T DO** |
| &nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp; Benchmark for total target compensation among our peers with an independent compensation consultant | &nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp; No hedging of our stock by employees |
| &nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp; Cap incentive program payments | &nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp; No pledging of our stock by employees |
| &nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp; Maintain a clawback policy | &nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp; No excessive perquisites |
| &nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp; Maintain robust stock ownership requirements | &nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp; No option repricing without stockholder approval |
| &nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp; Fully disclose incentive plan targets and results | &nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp; No evergreen provision in omnibus incentive plan |
| &nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp; Provide 50% of our annual long-term incentives in the form of performance-based compensation | &nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp; No delivery of payment of dividends on unvested equity awards prior to vesting |

---

We believe in paying for performance and that tying a significant portion of our named executive officers', or our NEOs', compensation to our long-term financial and growth objectives aligns the interests of our NEOs with the interests of our stockholders. For fiscal year 2022, the following factors highlight our commitment to our pay-for-performance philosophy:

• Approximately 82% of our Chief Executive Officer's target compensation and approximately 62% of our other NEOs' target compensation, on average, was "at risk" in that the ultimate realized value is dependent on the achievement of performance goals or subject to changes in our stock price;

• Approximately 61% of our Chief Executive Officer's target compensation and approximately 42% of our other NEOs' target compensation, on average, was granted in the form of long-term equity incentive compensation, the value of which is linked directly to our share price, further aligning management with the interests of our stockholders; and

• Approximately 51% of our Chief Executive Officer's target compensation and approximately 41% of our other NEOs' target compensation, on average, was contingent upon our achievement of pre-established net sales, Adjusted EBITDA and, in the case of PSUs, return on assets targets.

In each case, target compensation consists of base salary, target annual incentive awards and long-term incentive awards. For more information, see "Compensation Discussion and Analysis—Fiscal Year 2022—Compensation Tables and Narrative Disclosures—Summary Compensation Table." Figures may not sum to 100% due to rounding.

#### Fiscal Year 2022 Pay-for-Performance Alignment
At the beginning of fiscal year 2022, the compensation committee established performance targets for fiscal year 2022 executive compensation. Target net sales and Adjusted EBITDA goals for fiscal year 2022 were set at approximately $1.37 billion and $325 million, respectively, reflecting approximately 16.5% and 18.5% growth for such metrics year-over-year, and were intended to meet or exceed our annual guidance for the year and what the compensation committee considered appropriately challenging but reasonably achievable expectations for our performance at the time such targets were set. Actual results for fiscal year 2022 reflected approximately 15% net sales growth and approximately 10% Adjusted EBITDA growth year-over-year, below the annual incentive plan targets established by our compensation committee.

Consistent with our pay-for-performance philosophy and after adjustment for certain acquisitions not contemplated at the time our financial performance targets were established, our annual incentive plan for fiscal year 2022 paid out at approximately 63% of target for the financial performance component, compared to approximately 200% for fiscal year 2021. The financial performance component of the annual incentive awards for our NEOs makes up 75% of the total target awards.

Further, a decline in our stock price during fiscal year 2022 has correspondingly decreased the value of the long-term equity compensation previously granted to our executives. For example, the ultimate value of time-based restricted stock units, or RSUs, granted to our NEOs in fiscal year 2022 is linked directly to our share price. During fiscal year 2022, the value of the RSUs granted to our NEOs decreased by approximately 60%. Further, as a result of the decline in our stock price, all of the service-vesting, non-qualified stock options, or stock options, awarded to our NEOs to date have exercise prices above the share price of our common stock as of September 30, 2022. Such options will only provide value to our NEOs if our share price rises above the options' exercise prices in the future. Finally, while no PSUs have reached the end of their performance periods to date, our performance over fiscal year 2022 will impact their eventual value upon vesting, thereby continuing to align our NEOs' compensation to the value delivered to our stockholders. Total CEO compensation as reflected on the Summary Compensation Table for fiscal year 2022 declined approximately 20% compared to fiscal year 2021 due primarily to not meeting pre-established Company performance targets and the reduced payout of our annual incentive plan as a result.

The following chart illustrates our pay-for-performance compensation philosophy by comparing our CEO's fiscal years 2022 and 2021 total target compensation to his fiscal years 2022 and 2021 realizable compensation, shown against our common stock price performance during the fiscal year. Realizable compensation includes (i) base salary paid during the fiscal year, (ii) cash bonus compensation paid during the fiscal year, excluding annual incentive award amounts, (iii) actual earned annual cash incentive award amounts paid for the fiscal year, (iii) the value of long-term incentive awards granted during the fiscal year, measured as of the end of the fiscal year, and (iv) all other compensation actually paid or received for the fiscal year.

### Human Capital and Diversity, Equity and Inclusion
We are committed to social responsibility within our workforce and our community and have adopted human capital and human rights management policies to further our commitment to social responsibility. Our culture is driven by a shared passion for our values, mission and performance. It is an inclusive culture of innovative, growth-minded individuals committed to always doing the right thing, continuous improvement and solving problems for our customers and partners.

We compensate our employees according to our fair remuneration policies and believe deeply in paying for performance. We also provide attractive benefits that promote the health of our employees and their families including medical, dental and vision coverage, company-paid life insurance, short and long-term disability, health savings accounts, flexible spending accounts and an employee assistance program. We are also committed to the financial wellness of our employees and have launched several resources and policies in alignment with this, including a 401(k) plan with a company match, an employee stock purchase program with a company match, or the 2021 ESPP, a parental leave policy and a military leave policy for our active military members. We have implemented recruitment strategies that enable us to hire and retain diverse and highly talented employees that bring a diverse range of thought and skills to the business. Specifically, we have committed to include diverse candidates in any pool of candidates from which employees are chosen. In our employee selection process and the operation of our business, we adhere to equal employment opportunity policies. Additionally, we work to build an inclusive culture of continued learning by offering a comprehensive training program which includes diversity-focused and leadership development trainings in order to provide employees opportunities to broaden their perspective and develop their skills in application to the business.

Our employees frequently hear from executive management, especially the Chief Executive Officer, who leads all-employee town halls where he provides business updates, aligns employees to our mission and values, and answers questions submitted directly from employees. He also regularly meets with small groups of employees to receive their feedback on the business. On an annual basis, we distribute an employee engagement survey that allows us to identify areas of strength and opportunities for improvement to ensure continued engagement, satisfaction and retention of our employees. We are also proud to develop a culture that celebrates the individuality of our employees while providing a supportive team environment. We host quarterly, diversity-focused engagement events frequently featuring employees themselves, and even members from our Board of Directors. In fiscal 2022, we launched two new employee resource groups that provide resources and support to our employees and are active in our local communities. We also provide opportunities for employees to get involved in the community as volunteers, whether in support of sustainability or people-focused initiatives. We implemented an employee charitable match program that matched donations made by employees and contributes in recognition of volunteer hours served to eligible charitable organizations. These programs fall under our Bringing Forward the Best of AZEK culture initiative which focuses on Diversity, Equity and Inclusion (DEI), leadership development and values-alignment.

In recognition of creating a culture where employees feel highly engaged, appreciated and fulfilled, we were named one of Chicago Tribune's Top Workplaces for the second year in a row in 2022.

| &nbsp;&nbsp; **PROPOSAL NO. 1** | The election of four Class III directors to serve until our 2024 annual meeting of stockholders and until their successors are duly elected and qualified. | **FOR each nominee** |
| &nbsp;&nbsp; **PROPOSAL NO. 2** | Ratification of the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for our year ending September 30, 2023. | **FOR** |
| &nbsp;&nbsp; **PROPOSAL NO. 3** | Approval, on an advisory, non-binding basis, of the compensation of our named executive officers. | **FOR** |
| &nbsp;&nbsp; **PROPOSAL NO. 4** | Approval of an amendment to our restated certificate of incorporation to limit the liability of certain officers of the Company as permitted by recent amendments to Delaware law. | **FOR** |

---

Other than the four items of business described in this proxy statement, we are not aware of any other business to be acted upon at the Annual Meeting. You may be asked to consider any other business that properly comes before the Annual Meeting.

#### Who is entitled to vote?
Holders of our Class A common stock as of the close of business on the Record Date will be entitled to one vote for each share of our Class A common stock held by them on the Record Date with respect to all matters to be acted upon at the Annual Meeting. The sole holder of our Class B common stock as of the close of business on the Record Date will be entitled to one vote for each share of our Class B common stock held by it on the Record Date with respect to all matters to be acted upon at the Annual Meeting other than those matters that relate to the election, removal or replacement of directors. As of the Record Date, there were 150,728,023 shares of our Class A common stock and 100 shares of our Class B common stock outstanding. We refer to our Class A common stock and our Class B common stock collectively as our common stock. Stockholders do not have cumulative voting rights for the election of directors.

#### Why are there two classes of common stock and how are they different?
Our Class A common stock is ordinary common stock and is the class of stock owned by virtually all of our stockholders. Our Class B common stock is identical to Class A common stock, except it cannot vote for the election, replacement or removal of directors. Currently, there are only 100 shares of Class B common stock outstanding out of a total of approximately 151 million shares of our aggregate outstanding common stock, comprising less than 0.01% of our outstanding common stock. All shares of Class B common stock are held by one stockholder, Ontario Teachers' Pension Plan Board, or OTPP. We maintain Class B common stock because OTPP, as a Canadian pension fund, is prohibited from investing monies of the Ontario Teachers' Pension Plan, directly or indirectly, in securities of a corporation to which are attached more than 30% of the votes that may be cast for the election of directors of the corporation. When we became a public company, the Class B common stock was created to ensure OTPP's ability to continue to comply with applicable law, regardless of changes to our capital structure. In order to guarantee this protection and flexibility for OTPP, pursuant to our restated certificate of incorporation, or our Certificate, shares of Class A common stock and shares of Class B common stock are freely convertible into each other, provided that the converting stockholder already owns shares of Class B common stock. Because OTPP has always been, and remains, the only Class B stockholder, OTPP is the only stockholder that can ever own shares of Class B common stock, and it does so at their election.

---

------

#### Stockholders of r ecord; s har es r egistered in y our n ame
If shares of our common stock are registered directly in your name with our transfer agent, Equiniti Trust Company, you are considered the stockholder of record with respect to those shares, and the Notice was provided to you directly by us. As the stockholder of record, you have the right to grant your voting proxy and indicate your voting choices directly to the individuals listed on the proxy card or to vote virtually at the Annual Meeting. Throughout this proxy statement, we refer to these registered stockholders as "stockholders of record."

#### Street n ame stockholders
If shares of our common stock are held on your behalf in a brokerage account or by a bank or other nominee, you are considered to be the beneficial owner of shares that are held in "street name," and the Notice was forwarded to you by your broker, bank or other nominee, who is considered the stockholder of record with respect to those shares. As the beneficial owner, you have the right to direct your broker, bank or other nominee as to how to vote your shares in the manner provided in the voting instructions you receive from your broker, bank or other nominee. If you request a printed copy of our proxy materials by mail, your broker, bank or other nominee will provide a voting instruction form for you to use. Street name stockholders are also invited to attend the virtual Annual Meeting. However, because a street name stockholder is not the stockholder of record, you may not vote your shares of our common stock virtually at the Annual Meeting unless you follow your broker, bank or other nominee's procedures for obtaining a legal proxy. Throughout this proxy statement, we refer to stockholders who hold their shares through a broker, bank or other nominee as "street name stockholders."

#### How many votes are needed for approval of each proposal?

| | | |
|:---|:---|:---|
| &nbsp;&nbsp; **PROPOSAL** | &nbsp;&nbsp; **PROPOSAL** | **VOTE NEEDED FOR APPROVAL AND EFFECT OF**<br> **ABSTENTIONS AND BROKER NON-VOTES** |
| &nbsp;&nbsp; **PROPOSAL NO. 1** | The election of four Class III directors to serve until our 2024 annual meeting of stockholders and until their successors are duly elected and qualified. | Our bylaws state that, to be elected, a nominee must receive a plurality of the votes, which means that the nominees that receive the highest number of votes of the shares present in person or represented by proxy and entitled to vote on the election of directors at the Annual Meeting "FOR" are elected as directors. As a result, any shares not voted "FOR" a particular nominee (whether as a result of stockholder abstention or a broker non-vote) will have no effect on the outcome of this proposal. Brokers do not have authority to vote on this proposal without instructions from the beneficial owner. |
| &nbsp;&nbsp; **PROPOSAL NO. 2** | Ratification of the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for our year ending September 30, 2023. | The affirmative vote of the holders of a majority of the voting power of the shares of our common stock entitled to vote on the proposal that are present in person or represented by proxy at the Annual Meeting. Abstentions are considered votes present and entitled to vote on this proposal, and thus, will have the same effect as a vote against this proposal. This proposal is considered a routine matter with respect to which a broker or other nominee can generally vote in its discretion. Therefore, no broker non-votes are expected in connection with this proposal. |
| &nbsp;&nbsp; **PROPOSAL NO. 3** | Approval, on an advisory, non-binding basis, of the compensation of our named executive officers. | The affirmative vote of the holders of a majority of the voting power of the shares of our common stock entitled to vote on the proposal that are present in person or represented by proxy at the Annual Meeting. Abstentions are considered votes present and entitled to vote on this proposal, and thus, will have the same effect as a vote against this proposal. Broker non-votes are not counted as shares entitled to vote on this proposal, and thus, will have no effect on the outcome of the proposal. Brokers do not have authority to vote on this proposal without instructions from the beneficial owner. |
| &nbsp;&nbsp; **PROPOSAL NO. 4** | Approval of an amendment to our restated certificate of incorporation to limit the liability of certain officers of the Company as permitted by recent amendments to Delaware law. | Approval of the amendment requires the affirmative vote of the holders of a majority of the voting power of the shares of our Class A common stock and Class B common stock outstanding, voting together as a single class. Abstentions and broker non-votes, if any, will have the same effect as a vote against this proposal. Brokers do not have authority to vote on this proposal without instructions from the beneficial owner. |

Voting results will be tabulated and certified by the inspector of election appointed for the Annual Meeting.

#### What is a quorum?
A quorum is the minimum number of shares required to be present at the Annual Meeting to properly hold an annual meeting and conduct business under our bylaws and Delaware law. The presence in person or represented by proxy of the holders of a majority of the voting power of the shares of

stock issued and outstanding and entitled to vote on a matter at the Annual Meeting will constitute a quorum for that matter at the Annual Meeting. Where a separate vote by a class or classes is required for any matter, the holders of a majority of the outstanding shares of such class or classes, present in person or represented by proxy, shall constitute a quorum to take action with respect to that vote on that matter.

#### How do I vote?
If you are a stockholder of record, there are four ways to vote:

• By Internet at www.proxyvote.com, 24 hours a day, seven days a week, until **11:59 p.m. Eastern Time on February 27, 2023** (have your Notice or proxy card in hand when you visit the website);

• By toll-free telephone at 1-800-690-6903 until **11:59 p.m. Eastern Time on February 27, 2023** (have your Notice or proxy card in hand when you call);

• By completing and mailing your proxy card (if you received printed proxy materials) to be received by **6:00 p.m. Eastern Time on February 27, 2023**; or

• By attending the virtual meeting by visiting *www.virtualshareholdermeeting.com/AZEK2023*, where you may vote electronically and submit questions during the Annual Meeting. Please have your Notice or proxy card in hand when you visit the website. If you previously voted via the Internet (or by telephone or mail), you will not limit your right to vote online at the Annual Meeting.

VOTING VIA THE INTERNET OR BY TELEPHONE IS FAST AND CONVENIENT, AND YOUR VOTE IS IMMEDIATELY CONFIRMED AND TABULATED. VOTING EARLY WILL HELP AVOID ADDITIONAL SOLICITATION COSTS AND WILL NOT PREVENT YOU FROM VOTING ELECTRONICALLY DURING THE ANNUAL MEETING IF YOU WISH TO DO SO.

If you are a street name stockholder, you will receive voting instructions from your broker, bank or other nominee. You must follow the voting instructions provided by your broker, bank or other nominee in order to direct your broker, bank or other nominee on how to vote your shares. As discussed above, if you are a street name stockholder, you may not vote your shares electronically at the Annual Meeting unless you obtain a legal proxy from your broker, bank or other nominee.

#### Can I change my vote?
Yes. If you are a stockholder of record, you can change your vote or revoke your proxy any time by:

• entering a new vote by Internet or by telephone before the Annual Meeting;

• delivering a written notice of revocation or completing and returning a later-dated proxy card before 6:00 p.m. Eastern Time on February 27, 2023 to the Corporate Secretary of AZEK, in writing, at The AZEK Company Inc., 1330 W Fulton Street #350, Chicago, Illinois 60607; or

• attending and voting electronically at the virtual Annual Meeting (although attendance at the Annual Meeting will not, by itself, revoke a proxy).

If you are a street name stockholder, your broker, bank or other nominee can provide you with instructions on how to change your vote.

#### What is the effect of giving a proxy?
Proxies are solicited by and on behalf of our board of directors. Jesse Singh (our President and Chief Executive Officer), Peter Clifford (our Chief Financial Officer and Treasurer) and Morgan Walbridge (our Chief Legal Officer and Secretary) have been designated as proxy holders by our board of directors. When proxies are properly dated, executed and returned, the shares represented by such proxies will be voted at the Annual Meeting in accordance with the instructions of the stockholder. If no specific instructions are given, however, the shares will be voted in accordance with the recommendations of our board of directors as described above. If any matters not described in this proxy statement are properly presented at the Annual Meeting, the proxy holders will use their own judgment to determine how to vote the shares. If the Annual Meeting is postponed, adjourned or continued, the proxy holders can vote the shares on the new Annual Meeting date as well, unless you have properly revoked your proxy instructions, as described above.

#### Why did I receive a Notice of Internet Availability of Proxy Materials instead of a full set of proxy materials?
In accordance with the rules of the U.S. Securities and Exchange Commission, or the SEC, we have elected to furnish our proxy materials, including this proxy statement and our 2022 Annual Report, primarily via the Internet. The Notice containing instructions on how to access this proxy statement and our 2022 Annual Report is first being mailed on or about January 17, 2023 to all stockholders entitled to vote at the Annual Meeting. Stockholders may request to receive all future proxy materials in printed form by mail or electronically by email by following the instructions

contained in the Notice. We encourage stockholders to take advantage of the availability of our proxy materials on the Internet to help reduce the environmental impact and the cost of our annual meetings of stockholders.

#### How are proxies solicited for the Annual Meeting?
Our board of directors is soliciting proxies for use at the Annual Meeting. All expenses associated with this solicitation will be borne by us. We will reimburse brokers, banks and other nominees for reasonable expenses that they incur in sending our proxy materials to you if a broker, bank or other nominee holds shares of our common stock on your behalf. In addition, our directors and employees may also solicit proxies in person, by telephone, or by other means of communication. Our directors and employees will not be paid any additional compensation for soliciting proxies. We have also retained D.F. King & Co. to solicit proxies for a fee of $13,500 plus a reasonable amount to cover expenses.

#### How may my broker, bank or other nominee vote my shares if I fail to provide timely directions?
Brokers, banks and other nominees holding shares of our common stock in street name for their customers are generally required to vote such shares in the manner directed by their customers. In the absence of timely directions, your broker, bank or other nominee will have discretion to vote your shares on our sole "routine" matter: the proposal to ratify the appointment of PricewaterhouseCoopers LLP, or PwC, as our independent registered public accounting firm for our year ending September 30, 2023. Your broker, bank or other nominee will not have discretion to vote on the election of directors, the approval of the compensation of our named executive officers or the proposed amendment to our Certificate, each of which is a "non-routine" matter, absent direction from you. If the broker, bank or other nominee that holds your shares in street name returns a proxy card without voting on a non-routine proposal because it did not receive voting instructions from you on that proposal, this is referred to as a "broker non-vote." Broker non-votes are considered in determining whether a quorum exists at the Annual Meeting. The effect of broker non-votes on the outcome of each proposal to be voted on at the Annual Meeting is explained above.

#### Where can I find the voting results of the Annual Meeting?
We will announce preliminary voting results at the Annual Meeting. We will also disclose voting results on a Current Report on Form 8-K that we will file with the SEC within four business days after the Annual Meeting. If final voting results are not available to us in time to file a Current Report on Form 8-K within four business days after the Annual Meeting, we will file a Current Report on Form 8-K to publish preliminary results and will provide the final results in an amendment to the Current Report on Form 8-K as soon as they become available.

**I share an address with another stockholder, and we received only one paper copy of the proxy materials. How may I obtain an additional copy of the proxy materials?** 

The rules promulgated by the SEC permit companies, brokers, banks or other intermediaries to deliver a single copy of proxy materials, or, where applicable, a Notice of Internet Availability of Proxy Materials, to households at which two or more stockholders reside. Each stockholder, however, still receives a separate proxy card if he or she receives paper copies. This practice, known as "householding," is designed to reduce duplicate mailings and save significant printing and postage costs as well as natural resources. Stockholders sharing an address who have been previously notified by their broker, bank or other nominee and have consented to householding will receive only one copy of our proxy statement and annual report or Notice of Internet Availability of Proxy Materials. If you would like to opt out of this practice for future mailings and receive a separate proxy statement and annual report or Notice of Internet Availability of Proxy Materials for each stockholder sharing the same address, please contact your broker, bank or other nominee.

You may also obtain a separate proxy statement or annual report or Notice of Internet Availability of Proxy Materials without charge by sending a written request to Broadridge Householding Department, 51 Mercedes Way, Edgewood, New York 11717, or by calling Broadridge's Householding Department at 1-866-540-7095. We encourage stockholders to contact us by telephone instead of physical mail to help ensure timely receipt of any request for proxy materials. Additional copies of the proxy statement or annual report or Notice of Internet Availability of Proxy Materials will be sent promptly upon receipt of such request. Stockholders sharing an address that are receiving multiple copies of the proxy statement or annual report or Notice of Internet Availability of Proxy Materials can request delivery of a single copy of the proxy statement or annual report or Notice of Internet Availability of Proxy Materials by contacting their broker, bank or other nominee or sending a written request to Broadridge Householding Department at the address above or by calling 1-866-540-7095.

#### What is the deadline to propose stockholder actions and director nominations for consideration at next year's annual meeting of stockholders?
RULE 14A-8 STOCKHOLDER PROPOSALS

As prescribed by Rule 14a-8 under the Securities Exchange Act of 1934, as amended, or the Exchange Act, stockholders may present proper proposals for inclusion in our proxy statement and for consideration at next year's annual meeting of stockholders. For a Rule 14a-8 stockholder proposal to be timely and considered for inclusion in our proxy statement for our 2024 annual meeting of stockholders, the proposal must comply

with all applicable requirements of Rule 14a-8, including with respect to ownership of our common stock, and our Corporate Secretary must receive the written proposal at our principal executive offices by the deadline prescribed by Rule 14a-8 under the Exchange Act (provided that the 2024 annual meeting of stockholders is not held more than 30 days from the first anniversary of the Annual Meeting, the applicable deadline will be September 19, 2023). Stockholder proposals should be addressed to:

The AZEK Company Inc.

Attention: Corporate Secretary

1330 W Fulton Street #350

Chicago, Illinois 60607

If a stockholder who has notified us of his, her or its intention to present a Rule 14a-8 stockholder proposal at an annual meeting does not appear and a qualified representative of that stockholder does not appear to present his, her or its proposal at such annual meeting, such proposal shall be disregarded and we are not required to present the proposal for a vote at such annual meeting.

ADVANCE NOTICE STOCKHOLDER PROPOSALS

Our bylaws also establish an advance notice procedure for stockholders who wish to present a proper proposal, including director nominations, before an annual meeting of stockholders (regardless of whether the proposal is intended to be included in our proxy statement). Any such advance notice stockholder proposal, including director nominations, must comply with all of the requirements set forth in our Certificate, our bylaws and applicable laws, rules and regulations. Our bylaws provide that, for business to be properly brought before an annual meeting by a stockholder, (i) the stockholder must be a stockholder of record at the time of the giving of the notice and at the time of the annual meeting, (ii) the stockholder is entitled to vote at the meeting, (iii) the business must be a proper matter for stockholder action, and (iv) the stockholder must give timely written notice to our Corporate Secretary, which notice must contain the information specified in our bylaws. For an advance notice stockholder proposal, including director nominations, to be timely for our 2024 annual meeting of stockholders, our Corporate Secretary must receive the written proposal at our principal executive offices at the address listed above:

• not earlier than the close of business on 120 days prior to the anniversary of the Annual Meeting; and

• not later than the close of business on 90 days prior to the anniversary of the Annual Meeting.

In the event that we hold our 2024 annual meeting of stockholders more than 30 days before or more than 60 days after the one-year anniversary of the Annual Meeting, notice of an advance notice stockholder proposal must be received no earlier than the close of business on the 120th day before our 2024 annual meeting of stockholders and no later than the close of business on the later of the following two dates:

• the 90th day prior to our 2024 annual meeting of stockholders; or

• the 10th day following the day on which public announcement of the date of the 2024 annual meeting of stockholders is first made.

If a stockholder who has notified us of his, her or its intention to present an advance notice stockholder proposal, including director nominations, at an annual meeting does not appear and a qualified representative of that stockholder does not appear to present his, her or its proposal at such annual meeting, such proposal shall be disregarded and we are not required to present the proposal for a vote at such annual meeting.

You are advised to review our bylaws, which contain additional requirements regarding advance notice stockholder proposals, including director nominations.

RULE 14A-19 STOCKHOLDER PROPOSALS

To comply with the universal proxy rules, stockholders who intend to solicit in support of director nominees other than our nominees must comply with the advance notice procedures set forth in our bylaws and described above and provide a notice that sets forth the information required by Rule 14a-19 under the Exchange by no later than December 30, 2023. However, note that this date does not supersede any of the requirements or timing required by our bylaws.

#### Availability of amended and restated bylaws
A copy of our amended and restated bylaws is available via the SEC's website at https://www.sec.gov. You may also contact our Corporate Secretary at the address set forth above for a copy of the relevant bylaw provisions regarding the requirements for making stockholder proposals and nominating director candidates.

## BOARD OF DIRECTORS

### Board of Directors Composition
We are managed under the direction of our board of directors, which is currently composed of ten members. All of our directors, with the exception of our Chief Executive Officer, are independent within the meaning of the listing standards of the New York Stock Exchange, or the NYSE.

Our Certificate currently provides for a board of directors comprised of three classes of directors, with each class serving a three-year term beginning and ending in different years than those of the other two classes. Our board of directors is currently divided among the three classes as follows:

• Our Class I directors are Sallie Bailey, Vernon J. Nagel, Natasha Li and Ashfaq Qadri and their term will expire at the annual meeting of stockholders to be held in 2024.

• Our Class II directors are Fumbi Chima and Brian Spaly and their term will expire at the annual meeting of stockholders to be held in 2025.

• Our Class III directors are Gary Hendrickson, Howard Heckes, Bennett Rosenthal and Jesse Singh and their term will expire at the Annual Meeting. Each of Messrs. Hendrickson, Heckes, Rosenthal and Singh are standing for re-election at the Annual Meeting.

Our Certificate also provides for the phasing out of the classification of our board of directors. Our Class III directors to be elected at the Annual Meeting shall serve a one-year term and shall be subject to re-election at our annual meeting of stockholders to be held in 2024, alongside the election of our Class I directors. Beginning with our annual meeting of stockholders to be held in 2025, the declassification of our board of directors will be complete and all directors will be subject to annual election for one-year terms.

#### Director Term and Committee Membership Information
The following table sets forth the names, ages as of January 6, 2023, and certain other information for each of the members of our board of directors with terms expiring at the Annual Meeting (who are also nominees for election as a director at the Annual Meeting) and for each of the continuing members of our board of directors. Full biographical information follows the table.

## PROPOSAL NO. 1

## ELECTION OF DIRECTORS
Our board of directors is currently composed of ten members. In accordance with our Certificate, as currently in effect, our board of directors is divided into three classes of directors. The classification of our board of directors is currently being phased out, such that, beginning with our 2025 annual meeting of stockholders, the declassification of our board of directors will be complete and all directors will be subject to annual election for one-year terms.

At the Annual Meeting, four Class III directors will be elected for a one-year term to succeed the Class III directors whose term is then expiring. Each director's term continues until the election and qualification of his or her successor, or such director's earlier death, resignation, disqualification or removal.

### Nominees
Our nominating and corporate governance committee has recommended, and our board of directors has approved, Gary Hendrickson, Howard Heckes, Bennett Rosenthal and Jesse Singh as nominees for election as Class III directors at the Annual Meeting. If elected, each of Messrs. Hendrickson, Heckes, Rosenthal and Singh will serve as Class III directors until our 2024 annual meeting of stockholders and until their successors are duly elected and qualified, or until their earlier death, resignation, disqualification or removal. Each of the nominees is currently a director of the Company and has agreed to serve if elected. For information concerning the nominees, please see "Board of Directors—Nominees for Director."

If you are a stockholder of record and you sign your proxy card or vote by telephone or over the Internet but do not give instructions with respect to the voting of directors, your shares will be voted "FOR" the election of each of Messrs. Hendrickson, Heckes, Rosenthal and Singh. We expect that each of Messrs. Hendrickson, Heckes, Rosenthal and Singh will accept such nomination; however, in the event that a director nominee is unable or declines to serve as a director at the time of the Annual Meeting, the proxies will be voted for any nominee designated by our board of directors to fill such vacancy. If you are a street name stockholder and you do not give voting instructions to your broker, bank or other nominee, your broker, bank or other nominee will not vote your shares on this matter.

### Vote Required; Recommendation of the Board of Directors
Our bylaws state that, to be elected, a nominee must receive a plurality of the votes of the shares present in person or represented by proxy and entitled to vote on the election of directors at the Annual Meeting, which means that the individuals who receive the largest number of votes cast "FOR" are elected as directors. As a result, any shares not voted "FOR" a particular nominee (whether as a result of stockholder abstention or a broker non-vote) will have no effect on the outcome of this proposal. Brokers do not have authority to vote on this proposal without instructions from the beneficial owner.

**THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS VOTE "FOR" THE ELECTION OF EACH OF GARY HENDRICKSON, HOWARD HECKES, BENNETT ROSENTHAL AND JESSE SINGH TO THE BOARD FOR A ONE-YEAR TERM EXPIRING IN 2024.**

#### Board Lea dership
Our board of directors is responsible for the supervision and oversight of our business affairs. In executing this responsibility, our board of directors establishes corporate policies, sets strategic direction and oversees management. Our board of directors has not adopted a formal policy with respect to the separation of the offices of Chief Executive Officer and Chairperson of the Board. It is our board of directors' view that rather than having a rigid policy, our board of directors should determine, as and when appropriate upon consideration of all relevant factors and circumstances, whether the two offices should be separate. Currently, our leadership structure separates the offices of Chief Executive Officer and Chairperson of the Board, with Mr. Singh serving as our Chief Executive Officer and Mr. Hendrickson serving as non-executive Chairperson of the Board. We believe this is appropriate as it provides Mr. Singh with the ability to focus on our day-to-day operations while Mr. Hendrickson focuses on the oversight by our board of directors.

#### Director Independence
Pursuant to the corporate governance standards of the NYSE, a director employed by us cannot be deemed an "independent director," and each other director will qualify as "independent" only if our board of directors affirmatively determines that he has no material relationship with us, either directly or as a partner, stockholder or officer of an organization that has a relationship with us. In making such determinations, the board of directors considered that certain directors serve as directors of other companies with which we engage from time to time in the ordinary course of business and, in accordance with our independence standards, determined that none of these relationships were material or impaired the independence of any of our directors. The fact that a director may own our capital stock is not, by itself, considered a material relationship. Based on information provided by each director concerning his or her background, employment and affiliations, our board of directors has affirmatively determined that each of Gary Hendrickson, Sallie Bailey, Fumbi Chima, Howard Heckes, Natasha Li, Vernon J. Nagel, Ashfaq Qadri, Bennett Rosenthal and Brian Spaly are independent in accordance with the NYSE rules. There are no family relationships among any of our directors or executive officers.

In addition, our board of directors has determined that Sallie Bailey, Fumbi Chima, Gary Hendrickson, Howard Heckes, Vernon J. Nagel and Brian Spaly each satisfy the independence requirements for audit committee members under the listing standards of the NYSE and Rule 10A-3 of the Exchange Act. Each of Sallie Bailey, Howard Heckes and Vernon J. Nagel has been determined to be an "audit committee financial expert" as defined under SEC rules. All members of the audit committee are able to read and understand fundamental financial statements, are familiar with finance and accounting practices and principles and are financially literate.

#### Meetings of the Board of Directors
Our board of directors held four (4) meetings (including regularly scheduled and special meetings) during our fiscal year 2022. Every director attended 100% of the meetings of our board of directors and of any board committees of which he or she was a member during our fiscal year 2022. Our non-employee directors meet by themselves, without non-independent directors and management present, not less than two times per year. Meetings of our non-employee directors are presided over by the chairperson of our board of directors. Under our Corporate Governance Guidelines, directors are encouraged and expected to attend our annual meeting of stockholders. All of our directors serving at the time of our 2022 annual meeting of stockholders attended that meeting.

#### Board Committees
Our board of directors has three standing committees: an audit committee, a compensation committee and a nominating and corporate governance committee, each of which has the composition and responsibilities described below. From time to time, our board of directors may establish other committees to facilitate the management of our business. A copy of each committee's charter is posted on the environmental, social and governance section of our website, www.azekco.com. Members serve on these committees until their resignation or until as otherwise determined by our board.

in its continuing growth and success. Our Corporate Governance Guidelines may be amended by our board of directors at any time. A copy of our Corporate Governance Guidelines is available under the environmental, social and governance section of our website, www.azekco.com.

The nominating and corporate governance committee also considers candidates for director recommended by stockholders who submit such recommendations in writing to our Corporate Secretary and evaluates director candidates recommended by stockholders in the same way it evaluates candidates recommended by the other sources referenced above.

In accordance with our Corporate Governance Guidelines, the nominating and corporate governance committee identifies and considers candidates based on a diversity of skills, expertise, industry knowledge, diversity of opinion and perspectives and other attributes. The nominating and corporate governance committee has also committed to including candidates with a diversity of age, gender, ethnicity/race and education in any pool of candidates from which board of director nominees are chosen. The board of directors also confirms that our policy of non-discrimination applies in the selection of directors.

#### Code of Conduct and Ethics and Code of Ethics for Senior Financial Officers
We have adopted a Code of Conduct and Ethics for all officers, directors and employees. We have also adopted a Code of Ethics for Senior Financial Officers applicable to our Chief Executive Officer and senior financial officers. We intend to disclose future amendments to certain provisions of our Code of Ethics for Senior Financial Officers, or waivers of such provisions applicable to any principal executive officer, principal financial officer, principal accounting officer or other persons performing similar functions, on our website.

• Interactions and dealings with our auditors.

#### Hedging and Pledging Policies, Derivatives Trading
As part of our insider trading policy, all of our directors, officers and employees are prohibited from engaging in hedging and other monetization transactions (which may include prepaid variable forward contracts, equity swaps, collars and exchange funds) involving our securities, holding our securities in a margin account or pledging our securities as collateral for a loan. We also prohibit our directors, officers and employees from speculating in our equity securities, including through the use of short sales or by trading in options or other derivative securities with respect to our securities.

#### Stock Ownership Policy
We have adopted a stock ownership policy for our executives. Our stock ownership policy was put in place in connection with our initial public offering, or our IPO, and is intended to increase the alignment of interests between our executives and stockholders. The guidelines and policies of peers and, on a broader basis, industry practices were considered in developing this policy. Our policy provides the following:

---

| | |
|:---|:---|
| &nbsp;&nbsp;&nbsp; **Category** | **Ownership**<br> **Requirement**<br> **(multiple of base**<br> **salary)** |
| &nbsp;&nbsp;&nbsp; CEO | 6x |
| &nbsp;&nbsp;&nbsp; CFO/COO | 3x |
| &nbsp;&nbsp;&nbsp; Other CEO Direct Reports | 2x |
| &nbsp;&nbsp;&nbsp; Other Executive Officers | 1x |

---

Ownership requirements and progress toward their achievement are reviewed annually as part of the compensation planning process. The policy requires retention of 100% of net shares acquired upon any vesting or exercise of equity awards until the ownership requirements are met for our Chief Executive Officer and retention of 50% of net shares acquired upon any vesting or exercise of equity awards until the ownership requirements are met for our other executives. For purposes of the stock ownership policy, we include direct ownership of shares, beneficially owned shares held indirectly (e.g. by family members and trusts), and vested deferred stock units, or DSUs. Unvested stock awards and unexercised options are not included in determining whether an executive has achieved the ownership levels. The compensation committee is responsible for monitoring the application of our stock ownership policy. Each of our current named executive officers is in compliance with this policy.

---

| | | |
|:---|:---|:---|
| 2023 **THE AZEK COMPANY** Proxy Statement | 26 | CORPORATE GOVERNANCE |

---

------

We have also adopted a stock ownership policy for our directors that requires each non-employee director to hold 100% of after-tax shares from director equity awards until the director holds shares and DSUs with an aggregate value equal to five times the annual cash retainer paid to non-employee directors. All of our non-employee directors currently meet the requirements or are otherwise in compliance with the policy via the retention requirement.

#### Related Persons Transaction Policy
We have adopted formal written procedures for the review, approval or ratification of transactions with related persons, or the Related Persons Transaction Policy. The Related Persons Transaction Policy provides that the audit committee of our board of directors is charged with reviewing for approval or ratification all transactions with "related persons" (as defined in paragraph (a) of Item 404 of Regulation S-K) that are brought to the audit committee's attention. A copy of our Related Persons Transaction Policy is available under the environmental, social and governance section of our website, www.azekco.com. See "Related Person Transactions" below for a description of related person transactions for fiscal year 2022.

#### Role of the Board in Risk Oversight; Cybersecurity Risk
Our board of directors takes an active role in the oversight of risk management, while management is responsible for addressing the day-to-day risks facing our Company. While our board of directors has primary responsibility for overseeing risk management, our board of directors also delegates certain oversight responsibilities to its committees. For example, our audit committee oversees management of financial risks, including those related to our internal control over financial reporting and disclosure controls and procedures, audit and auditor matters and other accounting matters. With the assistance of our independent compensation consultant, our compensation committee regularly considers and evaluates risks related to our cash and equity-based compensation programs and practices as well as evaluates whether our compensation plans encourage participants to take excessive risks that are reasonably likely to have a material adverse effect on us. Our compensation committee believes that our compensation programs appropriately incentivize our executive officers to take prudent risks and are focused on both the short-term and the long-term interests of our stockholders, which is reflected by the fact that our executive officers receive a balanced mix of short-term and long-term, performance-based, variable compensation, as well as fixed salary compensation and long-term, service-based compensation. Our compensation committee also believes that excessive risk taking is mitigated by compensation policies we maintain, including our executive officer stock ownership policy, our hedging and pledging prohibitions and our clawback policy. Consistent with SEC disclosure requirements, the compensation committee has worked with management to assess compensation policies and practices for our employees and has concluded that such policies and practices do not create risks that are reasonably likely to have a material adverse effect on us. Our nominating and corporate governance committee oversees management of risks associated with director independence, conflicts of interest, composition and organization of our board of directors, director succession planning and corporate governance. While each committee is responsible for evaluating certain risks and overseeing the management of such risks, our full board of directors keeps itself regularly informed regarding such risks through committee reports and otherwise.

Cybersecurity has become a particularly acute area of risk for companies of all sizes and in all industries, including us. While management is responsible for our cybersecurity program and managing our cybersecurity risks, including our procedures and day-to-day operations, our audit committee oversees our enterprise risk assessment and management program, which includes oversight of cybersecurity risks. In performing its oversight responsibilities, our audit committee receives regular reports from, and meets with, our Chief Information Officer and Chief Information Security Officer not less frequently than twice annually to review our information technology and cybersecurity risk profile and to discuss our activities to manage those risks. We use a variety of security products and vendors to protect our information technology infrastructure and data. Our programs continue to adapt and mature as threats continue to evolve. We maintain data encryption, monitoring, loss prevention, data storage, identity / authentication controls, including two-factor authentication tools, and anti-malware and anti-virus solutions. We perform penetration tests and cyber simulations to practice our incident response procedures. Our cybersecurity plans are reviewed on an annual basis, and we prioritize new and updated programs as needed to respond to the cybersecurity risks we face. We train employees on cybersecurity risks semi-annually and generate internal phishing campaigns to assess the effectiveness of the training. We actively monitor and respond to security events, and within the last 36 months have successfully executed containment to prevent notifiable breaches or material production impact. Cyber insurance is evaluated and renewed annually to address the latest offerings. We also regularly review our privacy policies to ensure compliance with all applicable data privacy regulations. We update our privacy policies on our website following such updates.

#### Role of the Board in ESG Oversight
In 2021, we formalized our ESG strategy, which we call our FULL-CIRCLE ESG strategy. Our nominating and corporate governance committee oversees our corporate social responsibility and sustainability initiatives, including ESG-related policies, strategies and disclosures. To support the nominating and corporate governance committee in these efforts, we have established a management-level ESG Steering Committee consisting of leaders from across our organization. The ESG Steering Committee generally meets monthly and reports directly to our Chief Executive Officer. Further, during 2022, we issued our second annual ESG report, which outlined many of the sustainability and impact-focused initiatives we have undertaken as well as the progress we have made against our many commitments to positively impact our employees, customers, communities and the planet.

#### Communications with th e Board of Directors
Although we do not have a formal policy regarding communications with our board of directors, stockholders, employees and others who are interested in communicating with our board of directors may do so by writing to us at The AZEK Company Inc., Attn: Corporate Secretary, 1330 W Fulton Street #350, Chicago, Illinois 60607. The Corporate Secretary will forward to the chairperson of our board of directors and such other board members as may be deemed appropriate any such communication, provided that such communication addresses a legitimate business issue.

#### Non-Employee Director Compensation
DIRECTOR COMPENSATION PROGRAM

We have adopted a director compensation program that was developed primarily based on peer benchmark data in consultation with our independent compensation consultant. The program is annually reviewed, and, if appropriate, modified, by our compensation committee, also with the assistance of our independent compensation consultant. During fiscal year 2022, no changes were made as compared to our director compensation levels for fiscal year 2021. In addition, we allow our directors to defer compensation in the form of DSUs, which are subject to our director stock ownership policy describe above. The program provides the following compensation for non-employee directors:

• An annual cash retainer of $85,000, paid quarterly in arrears;

• An annual equity award of RSUs granted in connection with each annual stockholder meeting with a grant date fair value of $115,000 that vests at the earlier of the first anniversary of the grant date or the following annual stockholder holder meeting;

• A one-time inaugural equity award of RSUs granted to newly appointed non-employee directors with a grant date fair value of $105,000 that cliff-vests on the third anniversary of grant;

• An annual cash retainer of $20,000 for the chair of the audit committee, $17,500 for the chair of the compensation committee, and $15,000 for the chair of the nominating and governance committee, in each case paid quarterly in arrears; and

• An additional annual cash retainer of $50,000 for serving as our non-executive chair, paid quarterly in arrears (waived by Mr. Hendrickson for a period of four years following our IPO).

The following table sets forth information regarding the compensation earned for service on our board of directors during the year ended September 30, 2022 by the directors who were not also NEOs.

Hendrickson ($19) and Nagel ($24) and Ms. Chima ($46) during the fiscal year. Such incremental grant date fair value of DSUs is due to rounding when determining the number of DSUs to be issued as a result of the applicable director's election to defer some or all of his or her cash retainers. <br>

## PROPOSAL NO. 2

## RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
Our audit committee has appointed PwC as our independent registered public accounting firm to audit our consolidated financial statements for the year ending September 30, 2023. PwC has served as our independent registered public accounting firm since 2010.

At the Annual Meeting, our stockholders are being asked to ratify the appointment of PwC as our independent registered public accounting firm for the year ending September 30, 2023. Stockholder ratification of the selection of PwC as our independent registered public accounting firm is not required by Delaware law, our Certificate or our bylaws. However, our audit committee is submitting the appointment of PwC to our stockholders because we value our stockholders' views on our independent registered public accounting firm and as a matter of good corporate governance. Notwithstanding the appointment of PwC and even if our stockholders ratify the appointment, our audit committee, in its discretion, may appoint another independent registered public accounting firm at any time during the year if our audit committee believes that such a change would be in the best interests of our Company and our stockholders. If our stockholders do not ratify the appointment of PwC, our board of directors may reconsider the appointment. Representatives of PwC are expected to be present at the Annual Meeting, will have an opportunity to make a statement if they so desire, and are expected to be available to respond to appropriate questions from our stockholders.

### Fees Paid to the Independent Registered Public Accounting Firm
The audit committee engaged PwC to perform an annual audit of the Company's financial statements for fiscal year 2022. The audit committee was responsible for determination and approval of audit fees primarily based on audit scope, with consideration of audit team skills and experiences.

Pursuant to SEC rules, the fees billed by PwC are disclosed in the table below:

---

| | | |

---

------

ALL OTHER FEES

Consists of fees for permitted products and services other than those that meet the criteria above.

### Auditor Independence
In our fiscal year ended September 30, 2022, there were no other professional services provided by PwC, other than those listed above, that would have required our audit committee to consider their compatibility with maintaining the independence of PwC.

### Pre-Approval Policies and Procedures
Consistent with requirements of the SEC and the Public Company Accounting Oversight Board, or the PCAOB, regarding auditor independence, our audit committee is responsible for the appointment, compensation and oversight of the work of our independent registered public accounting firm. In recognition of this responsibility, our audit committee pre-approves all audit and permissible non-audit services provided by the independent registered public accounting firm. These services may include audit services, audit-related services, tax services and other services. All services provided by PwC in fiscal 2022 and 2021 were pre-approved by our audit committee.

### Vote Required ; Recommendation of the Board of Directors
The ratification of the appointment of PwC requires the affirmative vote of the holders of a majority of the voting power of the shares of our common stock entitled to vote on the proposal that are present in person or represented by proxy at the Annual Meeting and are voted for or against the proposal. Abstentions are considered votes present and entitled to vote on this proposal, and thus, will have the same effect as a vote against this proposal. This proposal is considered a routine matter with respect to which a broker or other nominee can generally vote in its discretion. Therefore, no broker non-votes are expected in connection with this proposal.

**THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS VOTE "FOR" THE RATIFICATION OF THE APPOINTMENT OF PRICEWATERHOUSECOOPERS LLP AS THE COMPANY'S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE CURRENT FISCAL YEAR.**

## REPORT OF THE AUDIT COMMITTEE
The audit committee is composed of directors who each satisfy the independence, financial literacy and other requirements of NYSE listing standards and U.S. federal securities laws.

The primary purpose of the audit committee is to assist our board of directors in overseeing (1) the integrity of our financial statements, (2) our compliance with legal and regulatory requirements, (3) our independent auditors' qualifications and independence, (4) the performance of the independent auditors and our internal audit function and (5) other matters as set forth in the audit committee's charter. The audit committee is further responsible for the appointment and oversight of our independent auditor and is involved in the selection of the independent auditor's lead audit partner.

Our management has responsibility for preparing our financial statements, for maintaining effective internal control over financial reporting and for assessing the effectiveness of internal control over financial reporting. PwC, the audit committee-appointed independent registered public accounting firm for the fiscal year ended September 30, 2022, is responsible for auditing our financial statements and expressing opinions on the conformity of our audited financial statements with generally accepted accounting principles and on management's assessment of the effectiveness of our internal control over financial reporting.

In its role of financial reporting oversight, the audit committee has reviewed and discussed the Company's audited financial statements for the year ended September 30, 2022 with management and PwC and reviewed and discussed the results of PwC's examination of the financial statements. The audit committee also discussed with management, PwC and our internal auditors, the quality and adequacy of our internal controls and the processes for assessing and monitoring risk. The audit committee reviewed with both PwC and our internal auditor their audit plans, audit scope and identification of audit risks.

Representatives of PwC attended all regularly scheduled meetings of the audit committee during the year ended September 30, 2022. The audit committee has discussed with PwC the matters required to be discussed by the PCAOB. The audit committee has also received the written disclosures and the letter from PwC required by applicable requirements of the PCAOB regarding the independent auditor's communications with the audit committee concerning independence and has discussed PwC's independence with PwC. In addition, the audit committee has received written material addressing PwC's internal quality control procedures and other matters. The audit committee also met with PwC and the head of Internal Audit, with and without management present, to discuss the results of their respective examinations, the reasonableness of significant judgments, the evaluations of the Company's internal control over financial reporting and the overall quality of the Company's financial reporting. Management has represented to the audit committee that the Company's consolidated financial statements were prepared in accordance with U.S. generally accepted accounting principles.

Based on the foregoing, the audit committee has recommended to our board of directors that such audited financial statements be included in our 2022 Annual Report as filed with the SEC.

Respectfully submitted by the members of the audit committee of the board of directors:

Sallie B. Bailey (Chairperson)

Fumbi Chima

Howard Heckes

Vernon J. Nagel

Brian Spaly

### Fiscal 2022 Company Performance and Pay-for-Performance Alignment

#### Fiscal Year 2022 Financial Performance Summary
During fiscal year 2022, we continued to execute against our strategy of delivering long-term, sustainable growth and value creation for our stockholders, customers, partners and employees and achieved impressive financial results in an increasingly challenging macroeconomic environment. Although net income decreased 19% year-over-year to $75.2 million, net sales for the year increased 15.0% year-over-year to $1.36 billion, and Adjusted EBITDA increased 9.8% year-over-year to $301.0 million. Adjusted EBITDA is a non-GAAP financial measure that we use in our incentive programs and should not be considered in isolation or as a substitute for any of our financial measures reported under generally accepted accounting principles, or GAAP. For a discussion of Adjusted EBITDA, including a reconciliation to net income, its closest comparable GAAP measure, see pages 45-48 of our 2022 Annual Report as filed with the SEC on November 29, 2022.

We launched several award-winning new product innovations and completed three tuck-in acquisitions, expanding and strengthening our already industry-leading portfolio. We also adopted our first share repurchase program and returned approximately $81 million in value to our stockholders through repurchases of our common stock during fiscal year 2022. Consistent with both our business and sustainability goals, we diverted approximately 500 million pounds of scrap and waste materials from landfills through our recycling programs and utilized approximately 56% of recycled inputs in our extruded products. We also made meaningful progress against our target of increasing the use of lower cost recycled materials in our products, including increasing our Advanced PVC™ decking technology to an important milestone of 60% recycled content.

#### Fiscal Year 2022 Pay-for-Performance Alignment
*Pay-for-Performance Philosophy*

We believe in paying for performance and that tying a significant portion of our NEOs' compensation to our long-term financial and growth objectives aligns our NEOs' interests with those of our stockholders. For each of our annual and long-term incentive programs, we believe that we establish aggressive, but achievable, goals and performance targets to properly incentivize our management team and align management's interests with the interests of our stockholders. For fiscal year 2022, the following factors highlight our commitment to our pay-for-performance philosophy:

• Approximately 82% of our Chief Executive Officer's target compensation and approximately 62% of our other NEOs' target compensation, on average, was "at risk" in that the ultimate realized value is dependent on the achievement of performance goals or subject to changes in our stock price;

• Approximately 61% of our Chief Executive Officer's target compensation and approximately 42% of our other NEOs' target compensation, on average, was granted in the form of long-term equity incentive compensation, the value of which is linked directly to our share price, further aligning management with the interests of our stockholders; and

• Approximately 51% of our Chief Executive Officer's target compensation and approximately 41% of our other NEOs' target compensation, on average, was contingent upon our achievement of pre-established net sales, Adjusted EBITDA and, in the case of PSUs, return on assets targets.

In each case, target compensation consists of base salary, target annual incentive awards and long-term incentive awards. For more information, see "Compensation Discussion and Analysis—Fiscal Year 2022—Compensation Tables and Narrative Disclosures—Summary Compensation Table."

*Pay-for-Performance Alignment*

At the beginning of fiscal year 2022, the compensation committee established performance targets for fiscal year 2022 executive compensation. Target net sales and Adjusted EBITDA goals for fiscal year 2022 were set at approximately $1.37 billion and $325 million, respectively, reflecting approximately 16.5% and 18.5% growth for such metrics year-over-year, and were intended to meet or exceed our annual guidance for the year and what the compensation committee considered appropriately challenging but reasonably achievable expectations for our performance at the time such targets were set. Actual results for fiscal year 2022 reflected approximately 15% net sales growth and approximately 10% Adjusted EBITDA growth year-over-year, below the annual incentive plan targets established by our compensation committee.

Consistent with our pay-for-performance philosophy and after adjustment for certain acquisitions not contemplated at the time our financial performance targets were established, our annual incentive plan for fiscal year 2022 paid out at approximately 63% of target for the financial performance component, compared to approximately 200% for fiscal year 2021. The financial performance component of the annual incentive awards for our NEOs makes up 75% of the total target awards.

Further, a decline in our stock price during fiscal year 2022 has correspondingly decreased the value of the long-term equity compensation previously granted to our executives. For example, the ultimate value of RSUs granted to our NEOs in fiscal year 2022 is linked directly to our share price. During fiscal year 2022, the value of the RSUs granted to our NEOs decreased by approximately 60%. Further, as a result of the decline in our stock price, all of the stock options awarded to our NEOs to date have exercise prices above the share price of our Class A common stock as of September 30, 2022. Such options will only provide value to our NEOs if our share price rises above the options' exercise prices in the future. Finally, while no PSUs have reached the end of their performance periods to date, our performance over fiscal year 2022 will impact their eventual value upon vesting, thereby continuing to align our NEOs' compensation to the value delivered to our stockholders.

#### CEO Target Compensation vs. Realizable Compensation
The following chart illustrates our pay-for-performance compensation philosophy by comparing our CEO's fiscal years 2022 and 2021 total target compensation to his realizable compensation over the same period, shown against our common stock price performance during the fiscal year. Realizable compensation includes (i) base salary paid during the fiscal year, (ii) cash bonus compensation paid during the fiscal year, excluding annual incentive award amounts, (iii) actual earned annual cash incentive award amounts paid for the fiscal year, (iii) the value of long-term incentive awards granted during the fiscal year, measured as of the end of the fiscal year, and (iv) all other compensation actually paid or received for the fiscal year.

![](ghr222usclso000055.jpg)

### Compensation Philosophy
Our executive compensation program is designed by our compensation committee to (i) align executive compensation with our financial and operational performance; (ii) attract, retain and motivate key executives critical to achieving our vision and strategy; and (iii) reward such executives for delivering desired business results and stockholder value.

Consistent with this philosophy, performance-based compensation represented a significant portion of our NEO's target total direct compensation for fiscal 2022. In particular, 100% of the cash incentive awards paid to our NEOs under our annual incentive plan are tied to pre-established financial and/or individual performance goals designed to be aligned with our operational and long-term strategic initiatives. In addition, 50% of the equity awards granted to our NEOs under our 2022 long-term incentive compensation program were PSUs, which vest based on pre-established financial goals and are awarded to incentivize achievement of our financial and performance goals over a multi-year timespan and tie our NEOs' compensation to those goals. 25% of such awards are granted in the form of stock options, which are awarded to motivate our NEOs by ensuring that they only have value to the extent the market price of our Class A common stock increases. The remaining 25% of such awards are granted in the form of RSUs, which are awarded in order to motivate our NEOs to continue their employment with us for many years. Our compensation committee believes that this balancing of RSUs, PSUs and stock options appropriately motivates our NEOs in furtherance of our success and our stockholders' realization of value.

We assess the market competitiveness of our executive compensation program based on peer group data to deliver a total package consisting of base salary, annual incentive awards, long-term incentive awards, retirement benefits and other perquisites intended to be competitive for the relevant market for executive talent and closely aligned with the interests of our stockholders. The compensation committee may position an executive's target compensation below or above the median range to balance our overall performance and the individual performance of our executive officers with our pay-for-performance philosophy. In setting target compensation levels, the compensation committee also considers an executive's experience and skill set, among other factors.

### Roles and Resp onsibilities

#### Role of the Compensation Committee
Our compensation committee is primarily responsible for establishing and overseeing our general compensation strategy. In addition, the compensation committee oversees our compensation and benefit plans and policies, administers our omnibus equity incentive plan and reviews and approves compensation decisions relating to our executive officers, including our Chief Executive Officer. Our compensation committee has structured our executive compensation program to align with a compensation philosophy that is based on several objectives, including instilling an ownership culture and linking the interests of our executive officers with those of our stockholders and our other stakeholders; paying for performance; rewarding executive officers for achievement of both our annual and longer-term financial and key operating goals; and facilitating the attraction, motivation and retention of highly talented executive leaders. In addition to structuring our overall executive compensation program, our compensation committee routinely reviews, with the assistance of management and our independent compensation consultant, the actual compensation of our executive officers in the context of both our corporate goals and performance and our performance relative to our peers, as well as our peers' executive compensation levels and programs. Further, our compensation committee reviews and approves annual grants and other incentive compensation awarded to our executive officers and certain other key employees, ensures that proper due diligence, deliberations and reviews of our executive compensation and overall compensation philosophy and strategy are conducted and oversees risks associated with our compensation practices. For more information regarding our compensation committee's management and oversight of compensation-related risks, see "Corporate Governance—Role of the Board in Risk Oversight; Cybersecurity Risk".

While our compensation committee reviews our executive compensation programs throughout the year, decisions with respect to salary increases, annual incentives and long-term incentives, including the metrics and goals used to measure the performance of our executive officers and other employees, are typically made during the first fiscal quarter of each fiscal year. These decisions follow discussions that our compensation committee holds with and without management and our independent compensation consultant. In determining annual and long-term compensation amounts, our compensation committee reviews our performance over the prior year and, more generally, the performance of each individual executive officer. In determining our Chief Executive Officer's compensation, our compensation committee considers, among other things, our performance relative to our peers, the value of incentive awards granted to Chief Executive Officers of our peers and the value of awards granted to our Chief Executive Officer in prior years. Consideration is also given to compensation elements such as bonuses and perquisites, if any. The compensation committee considers recommendations from our Chief Executive Officer regarding the compensation of our executive officers other than himself. Our Chief Executive Officer makes such recommendations regarding base salary and short-term and long-term compensation for our executive officers based on our results, an executive officer's individual contribution toward these results, the executive officer's role and performance of his or her duties and his or her achievement of individual goals. Our compensation committee then reviews the recommendations and other data, including various compensation survey data and publicly available data of our peers, and makes decisions as to the target total direct compensation for each executive officer, including our Chief Executive Officer, as well as each individual compensation element. While our Chief Executive Officer typically attends meetings of the compensation committee, the compensation committee meets outside the presence of our Chief Executive Officer when discussing his compensation and when discussing certain other matters.

#### Role of Management
Management, and in particular our Chief Executive Officer, consults with our compensation committee with respect to our overall compensation philosophy, our compensation programs and objectives and compensation decisions with respect to individual executives and other employees. Management also presents regularly to the compensation committee with respect to our performance and strategy, both in order to keep the compensation committee apprised of how our performance will impact outstanding incentive awards and to inform the compensation committee with respect to future compensation decision-making. Management also provides the compensation committee with individual evaluations of each executive officer in connection with determining such officer's achievement of personal objectives and such officer's target compensation for the following fiscal year.

#### Role of the Independent Compensation Consultant
Under its charter, our compensation committee has the right to retain or obtain the advice of compensation consultants, independent legal counsel and other advisers. For fiscal year 2022, our compensation committee retained Frederic W. Cook & Co., Inc., or FW Cook, as its independent compensation consultant. FW Cook primarily advised the compensation committee with respect to our compensation philosophy and objectives, our determination of appropriate peers for benchmarking executive compensation levels and practices, market pay levels, our executive compensation risk assessment, the positioning of our director and executive compensation policies within these frameworks, the forms of long-term incentive awards issued to our directors and executive officers, and our compensation-related proxy disclosure. The compensation committee consulted with FW Cook regularly throughout the year, and one or more representatives of FW Cook attended portions of our compensation committee meetings. The compensation committee considered the information presented by its independent compensation consultant, but all decisions regarding the compensation of our executive officers were made independently by the compensation committee. In fiscal year 2022, in compliance with SEC and NYSE rules, the compensation committee assessed the independence of FW Cook and concluded that no conflict of interest exists that would

------

prevent FW Cook from independently advising the compensation committee. FW Cook did not provide any services to us in fiscal year 2022 other than the services provided directly to the compensation committee.

### Benchmarking
Each year, our compensation committee, with the advice of our independent compensation consultant, evaluates each of our NEO's total direct compensation opportunity, which reflects that executive's base salary and target award amounts under both our annual incentive and long-term incentive plans, as well as the form of such long-term incentive awards, against total direct compensation opportunities for comparable executives of similarly-situated companies. The compensation committee does not necessarily set total compensation opportunities for our NEOs to be higher or lower than any specific peer company, nor does the compensation committee restrict compensation of our NEOs to any particular range based on our peers. The compensation committee does take such peers into consideration to determine whether our NEOs' individual total compensation opportunities are reasonable and appropriate in the context of such executive's background, performance, tenure with the Company and other factors. We strive to balance offering competitive compensation to attract and retain the best talent available with ensuring that such compensation remains aligned with our stockholders' and other stakeholders' objectives and best interests. As discussed in last year's proxy statement, we made certain changes to the peer group from the one used for fiscal year 2021. The companies included in our peer group for fiscal years 2022 and 2023 total direct compensation opportunity benchmarking purposes are below. As of the time when fiscal year 2022 compensation decisions were made, our revenue approximated the 25<sup>th</sup> percentile of the peer group, and our market capitalization approximated the median of our peer group.

For our NEOs, PSUs comprise 50% of the overall award, with RSUs and stock options each comprising 25%. |

---

### 2022 NEO Compensation Details

#### Base Salary
Base salaries are designed to be competitive and fairly compensate our executive officers, including our NEOs, for the responsibility level of each respective position. Our compensation committee reviews the salaries of our executive officers annually to determine whether adjustments are appropriate. In determining the base salaries for our executive officers, our compensation committee reviews each individual's role and responsibilities, previous year's salary and individual performance, as well as the base salaries of similarly situated executives at comparable companies from peer group and survey data. Annual adjustments are generally effective in January, but our compensation committee may also review the salaries of our executive officers in connection with a promotion or other change in responsibility.

The annual base salaries of the NEOs as of the end of fiscal year 2022 were $825,000 for Mr. Singh, $600,000 for Mr. Clifford, $400,000 for Ms. Toole, $440,000 for Mr. Skelly, and $390,000 for Ms. Walbridge. Mr. Singh received a merit-based base salary increase of 4.3% for fiscal year 2022 as

compared to his base salary for fiscal year 2021, and each of Mr. Skelly and Ms. Walbridge received a merit-based base salary increase of 3% for fiscal year 2022 as compared to their base salary for fiscal year 2021. Mr. Clifford and Ms. Toole did not receive an increase because they each began employment with us shortly before or shortly after the start of fiscal year 2022. Base salaries for Mr. Skelly and Ms. Walbridge also reflect increases from $407,050 and $360,000, respectively, to $440,000 and $390,000, respectively, as part of their respective promotions during fiscal year 2022.

#### Annual Incentive
Our annual incentive compensation is composed of cash compensation payable during the first fiscal quarter following the completion of each fiscal year. Annual incentive compensation is designed to motivate and reward achievement of corporate annual performance goals established by our compensation committee as well as performance with respect to annual goals of each individual executive officer. In determining an executive officer's actual annual incentive compensation payable following any particular fiscal year, our compensation committee measures the actual outcomes for each performance metric as compared to the pre-established, target goals, adjusting for matters such as material acquisitions as the compensation committee deems appropriate. For more information regarding our alignment of our NEO's compensation to our performance for fiscal year 2022, see "—Overview of Fiscal 2022 Company Performance and Pay-for-Performance Alignment." The annual incentive compensation paid to each of our NEOs for fiscal year 2022, including the methodology used to calculate such compensation, is described below.

TARGET INCENTIVE OPPORTUNITIES

For our executive officers, 75% of each individual's target annual incentive award is determined by reference to corporate objectives, which can be Company-wide, based on such individual's specific operating segment or a combination of both, and 25% of each individual's annual incentive award is based upon individual performance relative to individual goals established at the beginning of that fiscal year, including ESG goals. 10% of each executive officer's annual incentive compensation opportunity is tied to ESG objectives, highlighting our commitment to our ESG goals and performance. Payouts between threshold, target and maximum financial performance levels are generally interpolated on a straight-line basis, provided that the increase in payout between target and maximum levels is accelerated as compared to the increase between threshold and target levels to further incentive our executive officers and other employees to achieve our more ambitious goals. The target opportunity for fiscal year 2022 for each of the NEOs was as follows:

---

| | | |
|:---|:---|:---|
| &nbsp;&nbsp;&nbsp; **Named Executive Officer** | **Target**<br> **Annual**<br> **Incentive**<br> **(% of Base**<br> **Salary)** | **Target**<br> **Annual**<br> **Incentive ($)(1)** |
| &nbsp;&nbsp;&nbsp; Jesse Singh | 110% | 930887 |
| &nbsp;&nbsp;&nbsp; Peter Clifford | 75% | 467308 |
| &nbsp;&nbsp;&nbsp; Samara Toole | 50% | 192308 |
| &nbsp;&nbsp;&nbsp; Jonathan Skelly(2) | 50% | 154735 |
| &nbsp;&nbsp;&nbsp; Jonathan Skelly(3) | 65% | 76671 |
| &nbsp;&nbsp;&nbsp; Morgan Walbridge(2) | 40% | 98462 |
| &nbsp;&nbsp;&nbsp; Morgan Walbridge(3) | 50% | 67500 |

---

(1) Target annual incentive amounts are based on base salary paid during the fiscal year, rather than on the annualized base salary rate as in effect at the end of the fiscal year. Fiscal year 2022 included 27 payroll dates instead of the usual 26 bi-weekly payroll dates.

(2) Reflects the NEO's target annual incentive award for the period prior to his or her promotion during fiscal year 2022.

(3) Reflects the NEO's target annual incentive award for the period following his or her promotion during fiscal year 2022.

FINANCIAL PERFORMANCE OBJECTIVES

For the fiscal year 2022, the financial performance component of the annual incentive opportunities was determined based on our Adjusted EBITDA and net sales, excluding the impact of certain acquisitions in fiscal year 2022, and which accounted for 50% and 25%, respectively, of each NEO's aggregate annual incentive opportunity, except for Mr. Skelly 's prorated annual incentive opportunity following his promotion. Mr. Skelly's prorated annual incentive opportunity following his promotion was determined based on the Adjusted EBITDA and net sales of each of the Company and of the Residential segment, where each Adjusted EBITDA metric accounted for 25% of the aggregate prorated annual incentive opportunity and each net sales metric accounted for 12.5%. These metrics and their assigned weights were designed to motivate and reward our NEOs for achieving our fiscal year 2022 financial and operational objectives. We view each of these metrics as critical to driving sustainable stockholder value creation and continuing to grow our business.

The compensation committee uses a sliding scale to determine the payout against our financial performance. With respect to our Company-wide financial performance goals, for fiscal year 2022, the minimum threshold for any payment was 90% and 87% of target performance for our net sales and Adjusted EBITDA, respectively, performance below which would result in a payout of 0% of the target for that performance factor. Performance

------

at target would result in a payout of 100% the target payment for that factor, and the maximum payout was capped at 200% of the target payment if 113% and 119%, respectively, or more of the target performance was achieved. Performance falling within the ranges above are interpolated on a straight-line basis. Target net sales and Adjusted EBITDA performance for fiscal year 2022 reflected 16.5% and 18.5% growth for such metrics year-over-year and were intended to meet or exceed our annual guidance for the year and what the compensation committee considered appropriately challenging but reasonably achievable expectations for our performance at the time such targets are set. Each year, the compensation committee sets the performance ranges based upon the best available information and makes an informed decision as to where the threshold, target and maximum performance levels should be set. A similar methodology was applied for our Residential segment, which is described in more detail in the second succeeding table below.

The financial performance objectives and actual fiscal 2022 performance as determined for purposes of the annual incentive awards to each NEO, other than for Mr. Skelly following his promotion during fiscal year 2022 were as follows:

(2) Fiscal year 2022 actual performance was measured excluding the impact of certain acquisitions in fiscal year 2022.

INDIVIDUAL PERFORMANCE OBJECTIVES

For the remaining annual incentive payout, 15% was determined by our compensation committee based on the NEOs' individual performance relative to individual goals established at the beginning of the fiscal year, and 10% was determined based on such NEO's individual contributions to the achievement of our ESG goals. The maximum award that an NEO can earn for the individual performance component was 130% of the target incentive attributable to this metric, which maximum is intended to reward exceptional performance. Our compensation committee considers each NEO's individual performance to pre-established goals throughout the year and makes final determinations following each fiscal year end.

For each of our NEOs, such NEO's ESG-related performance was determined primarily in connection with our completion and communication of our annual ESG report and our Company-wide development of both our ESG as well as our diversity, equity and inclusion programs. Mr. Singh's ESG-related performance was also determined based on our continued strong safety performance, the exemplary diversity of the executive management team, as well as the number of awards and other recognitions received by the Company for its commitments to ESG and DEI initiatives.

After considering each NEO's self-assessment and an assessment by the Chief Executive Officer (for Messrs. Clifford and Skelly and Mses. Toole and Walbridge), our compensation committee determined that our NEOs achieved their individual performance goals as follows:

#### Long-Term Incentives
FISCAL YEAR 2022 LONG-TERM INCENTIVES

Our compensation committee administers our long-term incentive compensation program and approves grants of equity awards to each of our NEOs in the form of RSUs, PSUs and stock options. In determining the value of each grant, the compensation committee first determines the target dollar value that the grant will be equal to. In determining the target value, the compensation committee reviews market practice of comparable companies, historical values used for that executive officer and officers who have performed the same or similar roles and that individual's performance and expectations for future contributions to our business. The compensation committee also considers the aggregate cost of executive compensation, share usage under our 2020 Plan and potential dilution to our stockholders. Once a dollar value for a particular long-term incentive award is established, the compensation committee grants a number of RSUs, PSUs and stock options such that the value of the PSUs is equal to approximately 50% of the total long-term incentive award dollar value and the values of the RSUs and stock options are each equal to approximately 25% of the total long-term incentive award dollar value. The RSUs and stock options typically vest, subject to continued service through the applicable vesting date, in equal annual increments over a three-year period. Stock options have exercise prices based on the closing price of our Class A common stock on the grant date. PSUs cliff vest, subject to the achievement and certification by the compensation committee of specified performance objectives and continued employment by the NEO, following the third anniversary of the grant date. For more information regarding our alignment of our NEO's compensation to our performance for fiscal year 2022, see "—Overview of Fiscal 2022 Company Performance and Pay-for-Performance Alignment."

The long-term incentive compensation awarded to each of our NEOs for fiscal year 2022 is set forth below. The values set forth below reflect award values as determined by the compensation committee and may differ slightly from their grant date fair values, typically due to rounding and truncating of shares and stock options. Annual long-term incentive awards for a fiscal year are determined by our compensation committee and awarded during the first fiscal quarter of that fiscal year. In addition, for each of Mr. Skelly and Ms. Walbridge, the values set forth below include long-term incentive awards granted in connection with their respective promotions in fiscal year 2022 in order to reflect their long-term incentive award values had they been in their respective new positions since the beginning of the fiscal year. For Mr. Skelly, this award had a grant date fair value of $75,000. For Ms. Walbridge, this award had a grant date fair value of $95,000.

The PSUs vest, subject to the holder's continued employment with us, if, and only to the extent that, specific performance goals with respect our cumulative net sales (45% weighting), cumulative Adjusted EBITDA (45% weighting) and average return on net tangible assets, defined as our Adjusted EBITDA *less* depreciation *divided by* our average total tangible assets for the vesting period, (10% weighting) are met during the applicable three-year performance period. For each of the net sales and Adjusted EBITDA metrics, payout is at 100% if the target goal is achieved, payout is 50% of target if threshold performance is achieved and maximum payout is equal to 200% if stretch goals are achieved. For the average return on net tangible assets metric, payout is equal to 100% if the target goal is met or exceeded, and there is no payout if the target goal is not met.

#### Special One-Time Payments
In fiscal year 2022, Ms. Toole received RSUs with a grant date fair value of approximately $400,000 granted in connection with her commencement of employment with us in October 2021. Ms. Walbridge received a retentive equity grant, consisting of 50% PSUs, 25% RSUs and 25% stock options, with a grant date fair value of approximately $205,000 in connection with her promotion in fiscal year 2022.

#### Other Compensation and Benefits
Employee Benefits

The NEOs participate in a variety of insurance plans, including medical and dental welfare benefits on the same basis as our other employees. In lieu of long-term disability benefits provided to other executives, Mr. Singh is entitled, pursuant to his employment agreement, to a long-term disability insurance policy funded by us that provides a monthly benefit of $25,000 in the event of total and permanent disability. We offer reimbursement for physicals to certain of our employees, including the NEOs. We also offer financial and tax consulting and preparatory services to our executive officers, including our NEOs.

Retirement Plans

We maintain a tax-qualified defined contribution plan, the AZEK Company 401k Plan, in which all employees may contribute up to 100% of his or her salary, subject to Internal Revenue Code limits. We match 100% of the first 1% of an employee's salary contributed to the 401k Plan and 50% of the next 5%, for a total matching contribution of 3.5% on the first 6% of an employee's salary contributed to the 401k Plan. The NEOs are eligible to participate in the 401k Plan on the same terms as other participating employees.

Stock Ownership Policy and Hedging/Pledging Restrictions

Our NEOs are subject to our executive officer stock ownership policy as well as restrictions on hedging and pledging shares of our capital stock. For more information, see "Corporate Governance—Stock Ownership Policy" and "Corporate Governance—Hedging and Pledging Policies, Derivatives Trading."

Clawback Policy

In the event we are required to prepare an accounting restatement due to our material noncompliance with any financial reporting requirement under U.S. securities laws, our board of directors or an appropriate committee of the board may, in its discretion, direct us to recover from any executive officer the amount of erroneously awarded cash or equity incentive-based compensation to the extent permitted by governing law. We will revise our existing clawback policy or adopt an additional clawback policy that complies with the NYSE listing standards within the required timeframe.

Termination and Change-in-Control Benefits

The NEOs are entitled to certain severance and change in control benefits, the terms of which are described below under "Fiscal Year 2022—Compensation Tables and Related Disclosures—Potential Payments and Benefits upon Termination or Change-in-Control." We provide our NEOs with these severance and change-in-control benefits to assist us in recruiting and retaining talented individuals and to help us ensure the continued focus and dedication of our NEOs, notwithstanding any concern that they may have regarding their continued employment, including prior to or following a change in control transaction.

Other Compensation and Benefits

Other compensation for fiscal year 2022 includes items as set forth under "—Fiscal Year 2022—Compensation Tables and Related Disclosures—Summary Compensation Table."

#### Tax Considerations
The compensation committee considers tax deductibility and other tax implications when designing our executive compensation program. However, the compensation committee believes that there are certain circumstances where the provision of compensation that is not fully tax deductible, including by reason of Section 162(m) of the Internal Revenue Code, is more consistent with our compensation philosophy and objectives. The compensation committee retains discretion and flexibility to award non-deductible compensation to our NEOs as it deems appropriate and in furtherance of its compensation philosophy and objectives.

### Compensation Committee Interlocks and Insider Participation
None of our executive officers currently serves, or in the past fiscal year has served, as a member of the board of directors or compensation committee of any entity that has one or more executive officers serving on our board of directors or compensation committee. None of the members of the compensation committee is, nor has ever been, an officer or employee of our Company.

(1) The amounts in this column reflect the aggregate grant date fair value of RSUs and PSUs granted during the fiscal year, computed in accordance with Accounting Standards Codification 718 issued by the Financial Accounting Standards Board, or FASB ASC 718. The aggregate grant date fair values for PSUs are shown based on the probable outcome of the applicable performance criteria as of the grant date, which was "target" level achievement for fiscal years 2022 and 2021. Assuming maximum level of achievement, the grant date fair value of the PSUs for fiscal year 2022 for each of Messrs. Singh, Clifford and Skelly would be $2,660,052, $950,002 and $451,333, respectively, and for each of Mses. Toole and Walbridge would be 380,064 and $451,311, respectively. Assuming maximum level of achievement, the grant date fair value of the PSUs for fiscal year 2021 for each of Messrs. Singh and Skelly would be $2,470,062 and $356,298, respectively.

The amounts in this column for fiscal year 2020 reflect incremental compensation expense on restricted stock issued in connection with the conversion of Profits Interests in connection with our IPO, and, for Mr. Skelly, RSUs granted with a grant date fair value, computed in accordance with FASB ASC 718, of $750,007, granted on June 16, 2020 in connection with our IPO. For Mr. Singh, amounts in this column do not reflect new stock awards and are solely related to pre-IPO compensation arrangements

(2) The amounts in this column reflect the aggregate grant date fair value of stock options granted during the fiscal year. The grant date fair value of the stock options was computed in accordance with FASB ASC 718. For a description of the assumptions used to determine the compensation cost of these awards, see Note 14 to our Consolidated Financial Statements for the year ended September 30, 2022 included in our 2022 Annual Report, Note 13 to our Consolidated Financial Statements for the year ended September 30, 2021 included in our 2021 Annual Report and Note 12 to our Consolidated Financial Statements for the year ended September 30, 2020 included in our 2020 Annual Report.

(3) The amounts in this column represent annual incentive cash awards earned under our annual incentive program. See "—2022 NEO Compensation Details—Annual Incentive."

(4) The amounts shown in the "All Other Compensation" column for the year ended September 30, 2022 comprise a monthly cell phone stipend; insurance premiums with respect to a long-term disability policy paid on behalf of Mr. Singh; group term life insurance premiums; matching contributions under the AZEK Company 401(k) Plan, or the 401(k) Plan; HSA employer matching contributions; certain expenses related to Mr. Singh's and Ms. Toole's commutes to our headquarters in Chicago of $20,711 and $49,500, respectively; expenses related to financial and tax counseling services for our executive officers of $15,000 for each NEO; relocation costs for Mr. Clifford's relocation to Chicago of $335,656; and executive physical costs and certain de minimis gift card benefits.

(5) A significant portion of our NEOs' compensation is awarded in the form of long-term incentive compensation. Fiscal year 2021 was the first fiscal year wherein our NEOs were awarded annual long-term incentive compensation as part of our annual compensation review process at the outset of the fiscal year. Prior to fiscal year 2021, we had either been a private company or we had recently completed our IPO, and we had not yet awarded long-term incentive equity grants on an annual basis. A significant portion of our NEOs' equity awards while we were a private company were subject to performance-based vesting conditions that were achieved in connection with our IPO or shortly thereafter as a result of a secondary offering we completed in September 2020. We recognized an accounting modification related to these performance-based awards in connection with our IPO. For this reason, our NEOs' long-term incentive compensation for fiscal years 2022 and 2021 is lower than the long-term incentive compensation value reported for fiscal year 2020. We expect that our NEOs' regular annual long-term incentive compensation values will more closely resemble that of fiscal years 2022 and 2021 in future years, subject to decisions made by our compensation committee, our performance and other business, financial, operational and strategic changes. Our CEO's compensation for fiscal year 2020 was particularly impacted by our IPO, the secondary offering in September 2020 and the resulting accounting modification.

#### Additional Narrative Disclosures
Employment Agreements

CPG International LLC entered into an employment agreement or offer letter with each of the NEOs in connection with the commencement of his or her employment.

*Restrictive Covenants. In connection with the commencement of his or her employment, each of the NEOs agreed to confidentiality, non-disparagement, non-competition and non-solicitation of employees and customers covenants. The non-competition and non-solicitation covenants with each of the NEOs continue for two years following the termination of his employment for any reason. The NEOs also agreed to covenants assigning us rights to intellectual property.* 

*Severance Under Employment Agreements. Each employment agreement or offer letter, as applicable, provides for certain severance and termination benefits that are described under "—Potential Payments and Benefits upon Termination or Change in Control." Severance benefits to each of the NEOs are subject to his or her execution of a release in our favor and compliance with post-employment restrictive covenants.* 

IPO Incentive Awards

In connection with our IPO, we granted Mr. Singh a stock option award with a grant date fair value of $1,300,000 to enhance his alignment with our stockholders and Mr. Skelly an RSU award with a grant date fair value of $750,007 to provide retentive value. Mr. Singh's options vest ratably over four years, subject to continued employment. Mr. Skelly's RSU award vests on June 16, 2024, subject to continued employment.

Pre-IPO Long-Term Incentives

*Profits Interests*

Prior to our IPO, our former direct parent prior to our IPO, or the Partnership, granted time-vested and performance-vested Profits Interests to the NEOs.

In connection with our IPO, each outstanding Profits Interests award, including any award held by our NEOs, was exchanged for a number of shares of our Class A common stock determined based the number of Profits Interests and the hurdle amount applicable to the Profits Interests. Profits Interests that were vested at the time of our IPO were exchanged for vested shares of our Class A common stock. Profits Interests that were unvested at the time of our IPO were exchanged for restricted shares of Class A common stock granted under our 2020 Omnibus Incentive Compensation Plan, or our 2020 Plan, which remain eligible to vest generally pursuant to the same time-based and performance-based vesting conditions as the Profits Interests for which they were exchanged. The performance-based vesting conditions were satisfied in September 2020 in connection with our first secondary offering. The exchange of Profits Interests for shares of Class A common stock did not result in any accelerated vesting of the Profits Interests. However, the modification of the terms and conditions of the performance-based Profits Interest awards to implement the exchange was treated as a modification under FASB ASC 718, resulting in an incremental compensation expense, which is reported in the Summary Compensation Table for fiscal year 2020. For information regarding this modification, see Note 13 to our Consolidated Financial Statements for the year ended September 30, 2020 included in our 2020 Annual Report.

In addition, upon the closing of our IPO, each current employee and non-employee director who received shares in exchange for Profits Interests was granted options to purchase shares of our Class A common stock. This option grant was intended to restore to such holders the same leverage, or amount of equity at work, that the holder had with respect to Profits Interests prior to the exchange. The options were granted pursuant to our 2020 Plan and had a per-share exercise price equal to the IPO price. The options awarded to each such holder were vested or unvested in the same proportion as the corresponding Profits Interests award was vested and unvested immediately prior to our IPO, and the unvested options have the same time-based and performance-based vesting conditions as the original Profits Interests award. The performance-based vesting conditions were satisfied in September 2020 in connection with our first secondary offering.

## 2022 Pay Ratio Disclosure
As required by Item 402(u) of Regulation S-K, we are providing the ratio of the annual total compensation of Mr. Singh, our CEO, to the annual total compensation of our median employee.

The values for fiscal year 2022, our last completed fiscal year, are as follows:

• annual total compensation for our CEO as reported below in the Summary Compensation Table of $4,388,758; and

• annual total compensation for our median employee of $71,504.

Accordingly, the ratio of Mr. Singh's annual total compensation to our median employee's total compensation for 2022 was 61.4:1.

We have completed the process to identify our median employee as of the end of fiscal year 2022. The identification process involved examining the annualized base pay rate for all individuals (excluding our CEO) who were employed by us in the United States on September 30, 2022, the last day of fiscal year 2022. We included all employees, whether employed on a full-time and part-time basis, and excluded all employees located outside the United States (11 employees in Canada). Our employee population as of September 30, 2022 included 2,082 employees. We did not perform adjustments to the compensation paid to part-time employees to calculate what they would have been paid on a full-time basis. From this group, we identified a cohort of 51 employees consisting of the employee with the absolute median compensation value and the 25 employees above and 25 employees below that employee and chose our median employee after considering anomalous characteristics, including, among others, overtime, bonuses and tenure. Our median employee identified through the methodology outlined above, and their earnings for the period of October 1, 2021 to September 30, 2022, were used in the fiscal year 2022 CEO pay ratio calculation.

This information is being provided for compliance purposes and is a reasonable estimate calculated in a manner consistent with SEC rules, based on our internal records and the methodology described above. The SEC rules for identifying the median employee and in calculating the pay ratio allow companies to adopt a variety of methodologies, exclusions and assumptions that reflect their employee populations and compensation practices. As such, the pay ratio reported above may not be comparable to the pay ratio reported by other companies. We believe this pay ratio is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K. Neither the Compensation Committee nor management of the Company used the CEO pay ratio measure in making compensation decisions.

## PROPOSAL NO. 3

## ADVISORY VOTE ON EXECUTIVE COMPENSATION
Pursuant to Section 14A of the Exchange Act, we are providing our stockholders with the opportunity to vote to approve, on a non-binding, advisory basis, the compensation of our NEOs as set forth in this proxy statement in accordance with the compensation disclosure rules of the SEC. This proposal is also referred to as the "Say on Pay" vote. This is our first Say on Pay vote, and our current policy is to hold Say on Pay votes annually.

Our executive compensation program is designed by our compensation committee to (i) align executive compensation with our financial and operational performance; (ii) attract, retain and motivate key executives critical to achieving our vision and strategy; and (iii) reward such executives for delivering desired business results and stockholder value, all while protecting against excessive risk taking. Our Compensation Discussion & Analysis, which begins on page 35 of this proxy statement, describes in detail the components of our executive compensation program and the process by which our Board makes executive compensation decisions.

Target net sales and Adjusted EBITDA goals for fiscal year 2022 were set at approximately 16.5% and 18.5% growth for such metrics year-over-year and were intended to meet or exceed our annual guidance for the year and to be appropriately challenging but reasonably achievable expectations for our performance at the time such targets were set. Actual results for fiscal year 2022 reflected approximately 15% net sales growth and approximately 10% Adjusted EBITDA growth year-over-year. Therefore, consistent with our pay-for-performance philosophy, our annual incentive plan paid out at approximately 63% of target for the financial performance component, compared to approximately 200% for fiscal year 2021. Further, a decline in our stock price during fiscal year 2022 has correspondingly decreased the value of the long-term equity compensation previously granted to our executives. For example, the ultimate value of RSUs granted to our NEOs in fiscal year 2022 is linked directly to our share price. During fiscal year 2022, the value of the RSUs granted to our NEOs decreased by approximately 60%. Further, as a result of the decline in our stock price, all of the stock options awarded to our NEOs to date have exercise prices above the share price of our Class A common stock as of September 30, 2022. Such options will only provide value to our NEOs if our share price rises above the options' exercise prices in the future. Finally, while no PSUs have reached the end of their performance periods to date, our performance over fiscal year 2022 will impact their eventual value upon vesting, thereby continuing to align our NEOs' compensation to the value delivered to our stockholders.

For fiscal year 2022, approximately 82% of our CEO's target compensation and approximately 62% of our other NEOs' target compensation, on average, was "at risk" in that the ultimate realized value is dependent on the achievement of performance goals or subject to changes in our stock price. In addition, approximately 61% of our CEO's target compensation and approximately 42% of our other NEOs' target compensation, on average, was granted in the form of long-term equity incentive compensation, the value of which is linked directly to our share price, further aligning management with the interests of our stockholders. Finally, approximately 51% of our CEO's target compensation and approximately 41% of our other NEOs' target compensation, on average, was, or in the case of PSUs, is, contingent upon our achievement of pre-established financial targets.

This vote is non-binding; however, we highly value the opinions of our stockholders. Accordingly, the Board and the Compensation Committee will consider the outcome of this advisory vote in connection with future executive compensation decisions.

### Vote Required; Recommendation of the Board of Directors
We will consider the proposal to be passed if it receives the affirmative vote of the holders of a majority of the voting power of the shares of our common stock entitled to vote on the proposal that are present in person or represented by proxy at the Annual Meeting. Abstentions are considered votes present and entitled to vote on this proposal, and thus, will have the same effect as a vote against this proposal. Broker non-votes are not counted as shares entitled to vote on this proposal, and thus, will have no effect on the outcome of the proposal. Brokers do not have authority to vote on this proposal without instructions from the beneficial owner.

**THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS VOTE "FOR" THE APPROVAL OF COMPENSATION PAID TO THE NAMED EXECUTIVE OFFICERS FOR FISCAL YEAR 2022.**

## PROPOSAL NO. 4

## APPROVAL OF AMENDMENT TO OUR Restated CERTIFICATE OF INCORPORATION to limit the liability of certain officers of the Company as permitted by recent amendments to Delaware law
The State of Delaware, which is our state of incorporation, recently enacted legislation that enables Delaware companies to limit the liability of certain officers in limited circumstances. In light of this update, our board of directors has determined that it is advisable and in the best interests of us and our stockholders to amend our Certificate to add a provision exculpating certain of the Company's officers from liability in specific circumstances, as permitted by Delaware law. We refer to this proposed amendment as the Proposed Amendment. We believe it is necessary to provide protection to officers to the fullest extent permitted by law in order to attract and retain top talent. This protection has long been afforded to directors. Accordingly, the board of directors is asking our stockholders to approve and adopt the Proposed Amendment.

#### Background on the Proposed Amendment
In August 2022, the Delaware General Assembly amended Section 102(b)(7) of the Delaware General Corporation Law, or the DGCL, to authorize corporations to adopt a provision in their certificate of incorporation to eliminate or limit monetary liability of certain corporate officers for breach of the fiduciary duty of care. Previously, the DGCL allowed only exculpation of corporate directors for breach of the fiduciary duty of care. As amended, Section 102(b)(7) of the DGCL authorizes corporations to provide for exculpation of the following officers: (i) the corporation's president, chief executive officer, chief operating officer, chief financial officer, chief legal officer, controller, treasurer or chief accounting officer, (ii) "named executive officers" identified in the corporation's SEC filings, and (iii) individuals who have agreed to be identified as officers of the corporation.

Section 102(b)(7) only permits, and the Proposed Amendment would only permit, the exculpation of certain officers in connection with direct claims brought by stockholders, including class actions, but would not eliminate officers' monetary liability for breach of fiduciary duty claims brought by the corporation itself or for derivative claims brought by stockholders in the name of the corporation. In addition, as is currently the case with directors under our Certificate, the Proposed Amendment would not limit the liability of officers for any breach of the duty of loyalty to the corporation or its stockholders, any acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of the law and any transaction from which the officer derived an improper personal benefit. Article ELEVENTH in our Certificate currently provides for the exculpation of directors, but does not include a provision that allows for the exculpation of officers.

The board of directors believes it is important to provide protection from certain liabilities and expenses that may discourage prospective or current directors from accepting or continuing membership on corporate boards and prospective or current officers from serving corporations. In the absence of such protection, qualified directors and officers might be deterred from serving as directors or officers due to exposure to personal liability and the risk that substantial expense will be incurred in defending lawsuits, regardless of merit. In particular, the board of directors took into account the narrow class and type of claims from which such officers would be exculpated from liability pursuant to amended DGCL Section 102(b)(7), the limited number of our officers that would be impacted, and the benefits the board of directors believes would accrue to the Company by providing exculpation in accordance with DGCL Section 102(b)(7), including, without limitation, the ability to attract and retain key officers and the potential to reduce litigation costs associated with frivolous lawsuits.

Our board of directors balanced these considerations with our corporate governance guidelines and practices and determined that it is in the best interests of us and our stockholders to amend the current exculpation and liability provisions in Article ELEVENTH of our Certificate to extend exculpation protection to our officers in addition to our directors.

#### Overview of the Proposed Amendment
As discussed above, Article ELEVENTH in our Certificate currently provides for the exculpation of directors. This Proposal No. 4 requests that stockholders approve an amendment to Article ELEVENTH to extend the exculpation provision to certain of our officers as permitted by amended DGCL Section 102(b)(7). The Proposed Amendment would amend Article ELEVENTH so that it would state its entirety as follows:

"A director or officer of the Corporation shall not be liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a director or officer, as applicable, except to the extent that such exemption from liability or limitation is not permitted under the DGCL as currently in effect or as the same may hereafter be amended. If the DGCL is hereafter amended to authorize the further elimination or limitation of the liability of directors or officers, then the liability of directors or officers of the Corporation shall be eliminated or limited to the fullest extent authorized by the DGCL, as so amended. Notwithstanding any such amendment to the DGCL, the liability of an officer in any action by or in the right of the Corporation shall not be eliminated or limited by this Article ELEVENTH. No amendment, modification or repeal of this Article ELEVENTH or the adoption of any provision of the Certificate of Incorporation inconsistent with this Article ELEVENTH shall adversely affect any right or protection of a director or officer that exists at the time of such amendment, modification, repeal or adoption."

The general description of the Proposed Amendment set forth above is qualified in its entirety by reference to the proposed certificate of amendment to our Certificate, or the Certificate of Amendment, which is attached as Annex A to this proxy statement and marked to show that changes described above. Additions to the Certificate are indicated by double underlining and deletions to the Certificate are indicated by strike-outs.

#### Reasons for the Proposed Amendment
The board of directors believes it is appropriate for public companies in states that allow exculpation of officers to have exculpation clauses in their certificates of incorporation. The nature of the role of directors and officers often requires them to make decisions on crucial matters. Frequently, directors and officers must make decisions in response to time-sensitive opportunities and challenges, which can create substantial risk of investigations, claims, actions, suits or proceedings seeking to impose liability on the basis of hindsight, especially in the current litigious environment and regardless of merit. Limiting concern about personal risk would empower both directors and officers to best exercise their business judgment in furtherance of stockholder interests. We expect our peers to adopt exculpation clauses that limit the personal liability of officers in their certificates of incorporation, and failing to adopt the Proposed Amendment could impact our recruitment and retention of exceptional officer candidates that conclude that the potential exposure to liabilities, costs of defense and other risks of proceedings exceeds the benefits of serving as an officer of the Company.

For the reasons stated above, and upon the recommendation of the nominating and corporate governance committee, our board of directors adopted resolutions setting forth the Proposed Amendment, declared the Proposed Amendment advisable and in the best interests of the Company and our stockholders, and unanimously resolved to submit the Proposed Amendment to our stockholders for approval. The Board of Directors believes the Proposed Amendment would better position the Company to attract top officer candidates and retain our current officers and enable the officers to exercise their business judgment in furtherance of the interests of the stockholders without the potential for distraction posed by the risk of personal liability. Additionally, it would align the protections for our officers with those protections currently afforded to our directors.

The Proposed Amendment is not being proposed in response to any specific resignation, threat of resignation or refusal to serve by any officer.

#### Additional Information
If our stockholders approve the Proposed Amendment, it will become effective upon the filing of the Certificate of Amendment with the Delaware Secretary of State, which we anticipate doing as soon as practicable following stockholder approval of the Proposed Amendment. Other than the replacement of the existing Article ELEVENTH by the proposed Article ELEVENTH, the remainder of our Certificate will remain unchanged after effectiveness of the Certificate of Amendment. In addition, we intend to file a Second Restated Certificate of Incorporation to integrate the Proposed Amendment (if approved) into a single document. However, even if our stockholders approve the Proposed Amendment, our board of directors retains discretion under Delaware law not to implement it. If our board of directors were to exercise such discretion, we will publicly disclose that fact, and the Company's current exculpation provisions relating to directors will remain in place.

If our stockholders do not approve the Proposed Amendment, the Company's current exculpation provisions relating to directors will remain in place, and the Certificate of Amendment will not be filed with the Delaware Secretary of State.

### Vote Required; Recommendation of the Board of Directors
Approval of the Proposed Amendment requires the affirmative vote of the holders of a majority of the voting power of our Class A common stock and Class B common stock outstanding, voting together as a single class. Abstentions and broker non-votes, if any, have the same effect as an "against" vote. Brokers do not have authority to vote on the Proposed Amendments without instructions from the beneficial owner.

**THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS VOTE "FOR" THE AMENDMENT TO OUR CERTIFICATE TO REFLECT NEW DELAWARE LAW PROVISIONS REGARDING OFFICER EXCULPATION.**

The following table sets forth the beneficial ownership of our common stock as of December 15, 2022 by the following individuals or groups:

• each of our directors;

• each of our named executive officers;

• all of our directors and executive officers as a group; and

• each person, or group of affiliated persons, who is known by us to beneficially own more than 5% of our Class A common stock or Class B common stock.

The percentage ownership information shown in the table is based upon 151,080,295 shares of Class A common stock and 100 shares of Class B common stock outstanding as of December 15, 2022.

The beneficial ownership information presented below includes, for each beneficial owner, (i) shares of Class A common stock and Class B common stock beneficially owned (including restricted shares of Class A common stock) and (ii) shares issuable upon exercise of options to purchase shares of Class A common stock, shares of Class A common stock issuable upon the settlement of DSUs and shares of Class A common stock subject to RSUs, in each case that are vested or will vest within 60 days of December 15, 2022. The beneficial ownership information presented below does not include shares issuable upon the exercise of options to purchase shares of Class A common stock, shares of Class A common stock issuable upon the settlement of DSUs or shares of Class A common stock subject to RSUs, in each case that will vest outside of such 60-day period. Shares subject to options, shares issuable upon the settlement of DSUs and shares subject to RSUs, in each case that are vested or will vest within 60 days of December 15, 2022, are deemed outstanding for purposes of calculating the percentage ownership of the person holding such options, DSUs or RSUs, but they are not deemed outstanding for purposes of calculating the percentage ownership of any other person.

We have determined beneficial ownership in accordance with the rules of the SEC. These rules generally attribute beneficial ownership of securities to persons who possess sole or shared voting power or investment power with respect to those securities, or have the right to acquire such powers within 60 days. Under these rules, more than one person may be deemed beneficial owner of the same securities and a person may be deemed to be a beneficial owner of securities as to which such person has no economic interest. The information contained in the following table is not necessarily indicative of beneficial ownership for any other purpose, and the inclusion of any shares in the table does not constitute an admission of beneficial ownership of those shares. Unless otherwise indicated, the persons or entities identified in this table have sole voting and investment power with respect to all shares shown as beneficially owned by them, subject to applicable community property laws.

## RELATED PERSON TRANSACTIONS
We describe below transactions and series of similar transactions, since the beginning of our last fiscal year, to which we have been or will be a participant in which:

• the amounts involved exceeded or will exceed $120,000; and

• any of our directors, nominees for director, executive officers or holders of more than 5% of our outstanding capital stock, or any immediate family member of, or person sharing the household with, any of these individuals or entities, had or will have a direct or indirect material interest.

### Stockholders Agreement
In connection with our IPO, we entered into the Stockholders Agreement with the Sponsors. Pursuant to the Stockholders Agreement, the Sponsors are entitled to designate individuals to be included in the slate of nominees for election to our board of directors as follows:

• for so long as the Sponsors collectively own 50% or more of the outstanding shares of our common stock, the greater of up to six directors and the number of directors comprising a majority of our board; and

• except as provided below, for so long as the Sponsors collectively own less than 50% of the outstanding shares of our common stock, that number of directors (rounded up to the nearest whole number or, if such rounding would cause the Sponsors to have the right to elect a majority of our board of directors, rounded to the nearest whole number) that is the same percentage of the total number of directors comprising our board as the collective percentage of common stock owned by the Sponsors.

Each of the Sponsors is entitled to nominate one-half of the nominees to be nominated unless (i) if the number of directors to be nominated is odd, in which case the Sponsors will jointly nominate one such director and each Sponsor will nominate one half of the remaining nominees, and (ii) if either Sponsor owns more than 5%, but less than or equal to 10%, of the outstanding shares of our common stock, in which case, one director will be nominated by such Sponsor, and the remaining nominees will be nominated by the other Sponsor.

Notwithstanding the foregoing, if either Sponsor at any time ceases to own more than 5% of the outstanding shares of our common stock, that Sponsor will not have the right to designate any directors, the shares of our common stock owned by that Sponsor will be excluded in calculating the thresholds above, and the rights set forth above will only be available to the Sponsor that holds the applicable percentage of shares of our common stock. The Stockholders Agreement also provides for the nomination to our board of directors, subject to his or her election by our stockholders at the annual meeting, of our Chief Executive Officer. Each Sponsor has agreed, for so long as such Sponsor holds more than 5% of the outstanding shares of our common stock, to vote all of the shares of Class A common stock held by it in favor of the foregoing nominees.

The Stockholders Agreement also grants each of the Sponsors certain information rights.

### Registration Rights Agreement
In connection with our IPO, we entered into a registration rights agreement, or the Registration Rights Agreement, with the Sponsors and certain members of our management. Subject to certain conditions, the Registration Rights Agreement provides the Sponsors with up to four "demand" registrations each and unlimited "demand" registrations at any time we are eligible to register shares on Form S-3. The Registration Rights Agreement also provides the Sponsors and certain members of our management with customary "piggyback" registration rights. The Registration Rights Agreement contains provisions for the coordination by the Sponsors of their sales of shares of our common stock and contains certain limitations on the ability of the members of our management party to the Registration Rights Agreement to offer, sell or otherwise dispose of shares of our common stock. The Registration Rights Agreement also provides that we will pay certain expenses of these holders relating to such registrations and indemnify them against certain liabilities which may arise under the Securities Act.

### Limitations of Liability; Indemnification of Officers and Directors
Our certificate of incorporation and bylaws provide that we will indemnify and advance expenses to our directors and officers, and may indemnify and advance expenses to our employees and other agents, to the fullest extent permitted by Delaware law, which prohibits our certificate of incorporation from limiting the liability of our directors for the following:

• any breach of the director's duty of loyalty to us or to our stockholders;

---

| | | |
|:---|:---|:---|
| 2023 **THE AZEK COMPANY** Proxy Statement | 61 | RELATED PERSON TRANSACTIONS |

---

------

• acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law;

• unlawful payment of dividends or unlawful stock repurchases or redemptions; and

• any transaction from which the director derived an improper personal benefit.

If Delaware law is amended to authorize corporate action further eliminating or limiting the personal liability of a director, then the liability of our directors will be eliminated or limited to the fullest extent permitted by Delaware law, as so amended. Our certificate of incorporation does not eliminate a director's duty of care and, in appropriate circumstances, equitable remedies, such as injunctive or other forms of non-monetary relief, remain available under Delaware law. This provision also does not affect a director's responsibilities under any other laws, such as the federal securities laws or other state or federal laws. Under our certificate of incorporation and bylaws, we will also be empowered to purchase insurance on behalf of any person whom we are required or permitted to indemnify.

In addition to the indemnification and advancement of expenses required in our certificate of incorporation and bylaws, we have entered into indemnification agreements with each of our current directors and executive officers. See "Corporate Governance—Director and Officer Indemnification Agreements"

The limitation of liability, indemnification and advancement provisions in our certificate of incorporation and bylaws may discourage stockholders from bringing a lawsuit against directors for breach of their fiduciary duties. They may also reduce the likelihood of derivative litigation against directors and officers, even though an action, if successful, might benefit us and our stockholders. A stockholder's investment may be harmed to the extent we pay the costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers and controlling persons pursuant to the foregoing provisions, or otherwise, we have been advised that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act, and is, therefore, unenforceable. There is no pending litigation or proceeding naming any of our directors or officers as to which indemnification is being sought, nor are we aware of any pending or threatened litigation that may result in claims for indemnification or advancement by any director or officer.

### Purchases of Products in the Ordinary Course of Business
Certain of our related persons may, either directly or through their respective affiliates, enter into commercial transactions with us from time to time in the ordinary course of business, primarily for the purchase of merchandise. We believe that none of the transactions with such persons is significant enough to be considered material to such persons or to us.
