#### Our Company
We are an industry-leading global designer, manufacturer and marketer of a broad portfolio of pool equipment and associated automation systems. With the pool as the centerpiece of the growing outdoor living space, the pool industry has attractive market characteristics, including significant aftermarket requirements, innovation-led growth opportunities and a favorable industry structure. We are a leader in this market with a highly recognized brand, one of the largest installed bases of pool equipment in the world, decades-long relationships with our key channel partners and trade customers and a history of technological innovation. Our engineered products, which include various energy efficient and more environmentally sustainable offerings, enhance the pool owner's outdoor living lifestyle while also delivering high quality water, pleasant ambiance and ease of use for the ultimate backyard experience. We believe that the residential pool industry will continue to experience broader smart pool pad conversion as consumers seek to extend home automation from inside the house to the backyard, and our suite of SmartPad<sup>TM</sup> products were developed to seize upon this trend.

#### RISK FACTORS
 *An investment in our common stock involves various risks. You should carefully consider the following risks and all of the other information contained in this prospectus supplement and the accompanying prospectus before investing in our common stock. In addition, you should read and consider the risk factors associated with our business included in the documents incorporated by reference in this prospectus supplement, including our [Annual Report on Form 10-K for the year ended December 31, 2022.](http://www.sec.gov/ix?doc=/Archives/edgar/data/1834622/000183462223000017/hayw-20221231.htm) See "Where You Can Find More Information." The risks described below and incorporated herein by reference are those which we believe are the material risks that we face. The trading price of our common stock could decline due to any of these risks, and you may lose all or part of your investment in our common stock.* 

#### Risks Related to Our Common Stock and this Offering
 ***Following the offering, affiliates of MSD Partners, L.P. ("MSD Partners") and CCMP Capital Advisors, LP ("CCMP") will continue to have significant influence over us, which could limit your ability to influence the outcome of key transactions, including a change of control.***

Upon the completion of this offering, based on the 212,623,140 shares of common stock outstanding as of February 24, 2023, affiliates of MSD Partners and CCMP will beneficially own approximately 33.65% and 14.84% of our outstanding common stock, respectively (or approximately 33.65% and 14.11%, respectively, if the underwriter exercises its option to purchase additional shares in full). For as long as MSD Partners and CCMP continue to beneficially own a substantial percentage of the voting power of our outstanding common stock, they will continue to have significant influence over us. For example, they will be able to strongly influence or effectively control the election of all of the members of our board of directors and our business and affairs, including any determinations with respect to mergers or other business combinations, the acquisition or disposition of assets, the incurrence of additional indebtedness, the issuance of any additional shares of common stock or other equity securities, the repurchase or redemption of shares of our common stock and the payment of dividends.

Additionally, MSD Partners and CCMP are in the business of making investments in companies and may acquire and hold interests in businesses that compete directly or indirectly with us. They may also pursue acquisition opportunities that may be complementary to our business, and, as a result, those acquisition opportunities may not be available to us.

 ***Following the consummation of this offering, we will no longer be a "controlled company" within the meaning of the New York Stock Exchange rules and, as a result, will no longer qualify for exemptions from certain corporate governance requirements.***

Our common stock is listed on the New York Stock Exchange. As a controlled company under New York Stock Exchange rules, we have not been subject to a number of corporate governance rules relating to composition of our board of directors and certain committees. Following the consummation of this offering, we will no longer be a "controlled company" withing the meaning of the New York Stock Exchange rules and, in accordance with such rules, would have to phase into compliance with certain requirements from which we are now exempt, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the requirement that a majority of the board of directors consist of independent directors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the requirement that we have a nominating/corporate governance committee that is composed entirely of independent directors with a written charter addressing the committee's purpose and responsibilities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the requirement that we have a compensation committee that is composed entirely of independent directors with a written charter addressing the committee's purpose and responsibilities; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the requirement for an annual performance evaluation of the nominating/corporate governance and compensation committees.

We intend to comply with these New York Stock Exchange rules during the phase-in period for compliance.

[**TABLE OF CONTENTS**](#TOC)

 ***Our stock price could be extremely volatile and, as a result, you may not be able to resell your shares at or above the price you paid for them.***

Since January 1, 2023, the price of our common stock, as reported on the New York Stock Exchange, has ranged from an intraday low of $9.56 on January 3, 2023 to an intraday high of $14.97 on February 2, 2023. In addition, the stock market in general has been highly volatile. As a result, the market price of our common stock is likely to be similarly volatile, and investors in our common stock may experience a decrease, which could be substantial, in the value of their stock, including decreases unrelated to our operating performance or prospects, and could lose part or all of their investment. The price of our common stock could be subject to wide fluctuations in response to a number of factors, including those described elsewhere herein and others such as:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • variations in our operating performance and the performance of our competitors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • actual or anticipated fluctuations in our quarterly or annual operating results;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • publication of research reports by securities analysts about us, our competitors or our industry;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • our failure or the failure of our competitors to meet analysts' projections or guidance that we or our competitors may give to the market;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • additions or departures of key personnel;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • strategic decisions by us or our competitors, such as acquisitions, divestitures, spin-offs, joint ventures, strategic investments or changes in business strategy;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the passage of legislation or other regulatory developments affecting us or our industry;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • changes in legislation, regulation and government policy as a result of the U.S. presidential and congressional elections;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • speculation in the press or investment community;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • changes in accounting principles;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • terrorist acts, acts of war or periods of widespread civil unrest;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • natural disasters and other calamities, including pandemics; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • changes in general market and economic conditions.

In addition, broad market and industry factors may negatively affect the market price of our common stock, regardless of our actual operating performance, and factors beyond our control may cause our stock price to decline rapidly and unexpectedly.

In the past, securities class action litigation has often been initiated against companies following periods of volatility in their stock price. This type of litigation could result in substantial costs and divert our management's attention and resources, and could also require us to make substantial payments to satisfy judgments or to settle litigation.

 ***Your percentage ownership in us may be diluted by future issuances of capital stock, which could reduce your influence over matters on which stockholders vote.***

Our board of directors has the authority, without action or vote of our stockholders, to issue all or any part of our authorized but unissued shares of common stock, including shares issuable upon exercise of options, or shares of our authorized but unissued preferred stock, subject to the applicable rules of the New York Stock Exchange. Issuances of common stock or voting preferred stock would reduce your influence over matters on which our stockholders vote and, in the case of issuances of preferred stock, would likely result in your interest in us being subject to the prior rights of holders of that preferred stock.

 ***There may be sales of a substantial amount of our common stock after this offering by our current stockholders, and these sales could cause the price of our common stock to fall.***

As of February 24, 2023, there were 212,623,140 shares of our common stock outstanding. Of our issued and outstanding shares, all of our common stock is freely transferable, except for any shares held by

------

[**TABLE OF CONTENTS**](#TOC)

our "affiliates," as that term is defined in Rule 144 under the Securities Act of 1933, as amended (the "Securities Act"). Upon the completion of this offering, MSD Partners and CCMP will beneficially own approximately 33.65% and 14.84% of our outstanding common stock, respectively (or approximately 33.65% and 14.11%, respectively, if the underwriter exercises its option to purchase additional shares in full). Sales of substantial amounts of our common stock in the public market after this offering, or the perception that such sales will occur, could adversely affect the market price of our common stock and make it difficult for us to raise funds through securities offerings in the future.

In connection with this offering, we, each of our officers and directors and each of the selling stockholders have entered into a lock-up agreement with the underwriter, which regulates their sales of our common stock for a period of 30 days after the date of this prospectus supplement, subject to certain exceptions.

#### Provisions in our charter documents and Delaware law may deter takeover efforts that may be beneficial to stockholder value.
In addition to MSD Partners' and CCMP's beneficial ownership of a substantial percentage of our common stock, provisions in our certificate of incorporation, as currently amended ("our certificate of incorporation") and bylaws and Delaware law could make it harder for a third party to acquire us, even if doing so might be beneficial to our stockholders, and could also make it difficult for stockholders to elect directors that are not nominated by the current members of our Board of Directors or take other corporate actions, including effecting changes in our management. These provisions include a classified board of directors and the ability of our Board of Directors to issue preferred stock without stockholder approval that could be used to dilute a potential hostile acquiror. Our certificate of incorporation will also impose some restrictions on mergers and other business combinations between us and any holder of 15% or more of our outstanding common stock other than MSD Partners, CCMP, and Alberta Investment Management Corporation ("AIMCo"). As a result, stockholders may lose their ability to sell their stock for a price in excess of the prevailing market price due to these protective measures, and efforts by stockholders to change the direction or management of the company may be unsuccessful.

 ***Our certificate of incorporation, as currently amended, designates specific courts as the sole and exclusive forum for certain claims or causes of action that may be brought by our stockholders, which could discourage lawsuits against us and our directors and officers.***

Our certificate of incorporation further provides that the federal district courts of the United States of America are the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act. In addition, our certificate of incorporation provides that any person or entity purchasing or otherwise acquiring any interest in the shares of capital stock of the Company will be deemed to have notice of and consented to these choice-of-forum provisions and waived any argument relating to the inconvenience of the forums in connection with any Covered Claim.

------

[**TABLE OF CONTENTS**](#TOC)

The choice of forum provisions contained in our certificate of incorporation may limit a stockholder's ability to bring a claim in a judicial forum that it finds favorable for disputes with us or any of our directors, officers, other employees or stockholders, which may discourage lawsuits with respect to such claims, although our stockholders will not be deemed to have waived our compliance with federal securities laws and the rules and regulations thereunder. While the Delaware courts have determined that such choice of forum provisions are facially valid, it is possible that a court of law in another jurisdiction could rule that the choice of forum provisions contained in our certificate of incorporation are inapplicable or unenforceable if they are challenged in a proceeding or otherwise, which could cause us to incur additional costs associated with resolving such action in other jurisdictions.

 ***We may not pay additional dividends on our common stock and, consequentially, you may not receive any return on investment unless you sell your common stock for a price greater than that which you paid for it.***

Any decision to declare and pay special or regular dividends will be made at the discretion of our board of directors and will depend on, among other things, our results of operations, financial condition, cash requirements, contractual restrictions and other factors that our board of directors may deem relevant. In addition, our ability to pay dividends may be limited by covenants of any existing and future outstanding indebtedness we or our subsidiaries incur, including our credit facilities and outstanding notes. As a result, you may not receive any return on an investment in our common stock unless you sell your common stock for a price greater than that which you paid for it.

#### CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS
This prospectus supplement, the accompanying prospectus and the documents incorporated by reference herein and therein contain certain statements that are "forward-looking statements" as that term is defined under the Private Securities Litigation Reform Act of 1995 (the "Act") and releases issued by the SEC. Such forward-looking statements relating to us are based on the beliefs of our management as well as assumptions made by, and information currently available to, us. These forward-looking statements include, but are not limited to, statements about our strategies, plans, objectives, expectations, intentions, expenditures and assumptions and other statements contained in or incorporated by reference in the Annual Report on Form 10-K that are not historical facts. When used in this document, words such as "may," "will," "should," "could," "intend," "potential," "continue," "anticipate," "believe," "estimate," "expect," "plan," "target," "predict," "project," "seek" and similar expressions as they relate to us are intended to identify forward-looking statements. We believe that it is important to communicate our future expectations to our shareholders, and we therefore make forward-looking statements in reliance upon the safe harbor provisions of the Act. However, there may be events in the future that we are not able to accurately predict or control, and actual results may differ materially from the expectations we describe in our forward-looking statements.

Examples of forward-looking statements include, among others, statements we make regarding: our financial position; business plans and objectives; general economic and industry trends; business prospects; future product development and acquisition strategies; growth and expansion opportunities; operating results; and working capital and liquidity. The forward-looking statements in the Annual Report on Form 10-K are only predictions. We may not achieve the plans, intentions or expectations disclosed in our forward-looking statements, and you should not place significant reliance on our forward-looking statements. We have based these forward-looking statements largely on our current expectations and projections about future events and financial trends that we believe may affect our business, financial condition and results of operations. Moreover, neither we nor any other person assumes responsibility for the accuracy and completeness of forward-looking statements taken from third-party industry and market reports.

Important factors that could affect our future results and could cause those results or other outcomes to differ materially from those indicated in our forward-looking statements include the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • our relationship with and the performance of distributors, builders, buying groups, retailers and servicers who sell our products to pool owners;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • impacts on our business from the sensitivity of our business to seasonality and unfavorable economic and business conditions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • competition from national and global companies, as well as lower-cost manufacturers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • our ability to develop, manufacture and effectively and profitably market and sell our new planned and future products;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • our ability to execute on our growth strategies and expansion opportunities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • impacts on our business from political, regulatory, economic, trade, and other risks associated with operating foreign businesses, including risks associated with geopolitical conflict;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • our ability to maintain favorable relationships with suppliers and manage disruptions to our global supply chain and the availability of raw materials, including as a result of the COVID-19 pandemic;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • our ability to identify emerging technological and other trends in our target end markets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • failure of markets to accept new product introductions and enhancements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the ability to successfully identify, finance, complete and integrate acquisitions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • our reliance on information technology systems and susceptibility to threats to those systems, including cybersecurity threats, and risks arising from our collection and use of personal information data;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • regulatory changes and developments affecting our current and future products;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • volatility in currency exchange rates and interest rates;

------

[**TABLE OF CONTENTS**](#TOC)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • our ability to service our existing indebtedness and obtain additional capital to finance operations and our growth opportunities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • our ability to establish and maintain intellectual property protection for our products, as well as our ability to operate our business without infringing, misappropriating or otherwise violating the intellectual property rights of others;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the impact of material cost and other inflation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • our ability to attract and retain senior management and other qualified personnel;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the impact of changes in laws, regulations and administrative policy, including those that limit U.S. tax benefits, impact trade agreements and tariffs, or address the impacts of climate change;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the outcome of litigation and governmental proceedings; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the impact of product manufacturing disruptions, including as a result of catastrophic and other events beyond our control, including risks associated with geopolitical conflict.

While we believe the expectations reflected in such forward-looking statements are reasonable, we can give no assurance such expectations will prove to have been correct. There are a variety of factors which could cause future outcomes to differ materially from those described or incorporated by reference in this prospectus supplement or the accompanying prospectus including, but not limited to, the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Our business depends on the performance of distributors, builders, buying groups, retailers and servicers.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • The demand for our swimming pool equipment products may be adversely affected by unfavorable economic and business conditions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • We compete in markets with high levels of competition, which may result in pressure on our profit margins and limit our ability to maintain or increase the market share of our products.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Our future success depends on developing, manufacturing and attaining market adoption of new products.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Past growth may not be indicative of future growth.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Our results of operations and cash flows may fluctuate from quarter to quarter for many reasons, including seasonality and weather conditions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • A loss of, or material cancellation, reduction or delay in purchases by, one or more of our largest customers could harm our business.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • We are exposed to credit risk on our accounts receivable and this risk is heightened during periods when economic conditions worsen.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • We are exposed to political, regulatory, economic, trade, and other risks that arise from our international business operations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Changes in U.S. or foreign government administrative policy, including changes to existing trade agreements, could have a material adverse effect on us.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Sales of counterfeit versions of our products, as well as unauthorized sales of our products, may adversely affect our reputation, business, financial condition, results of operations and cash flows.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • We rely on access to intellectual property owned by third parties, so our rights to develop and commercialize certain products are subject to the terms and conditions of licenses granted to us by others.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • We may be subject to claims that our employees, consultants, or advisors have wrongfully used or disclosed alleged trade secrets of their current or former employers or claims asserting ownership of what we regard as our own intellectual property.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Third parties may initiate legal proceedings alleging that we are infringing, misappropriating, or otherwise violating their intellectual property rights, the outcome of which would be uncertain and could have a material adverse effect on the success of our business.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • We may not be able to effectively enforce our intellectual property rights throughout the world.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Recent changes in U.S. patent laws may limit our ability to obtain, defend, and/or enforce our patents.

#### MATERIAL U.S. FEDERAL INCOME AND ESTATE TAX CONSIDERATIONS FOR NON-U.S. HOLDERS OF COMMON STOCK
The following is a summary of the material U.S. federal income and estate tax considerations relating to the purchase, ownership and disposition of our common stock by Non-U.S. Holders (defined below). This summary does not purport to be a complete analysis of all the potential tax considerations relevant to Non-U.S. Holders. This summary is based upon the Internal Revenue Code of 1986, as amended (the "Internal Revenue Code"), the Treasury regulations promulgated or proposed thereunder and administrative and judicial interpretations thereof, all as of the date hereof and all of which are subject to change at any time, possibly on a retroactive basis.

This summary assumes that shares of our common stock are held as "capital assets" within the meaning of Section 1221 of the Internal Revenue Code. This summary does not purport to deal with all aspects of U.S. federal income and estate taxation that might be relevant to particular Non-U.S. Holders in light of their particular investment circumstances or status, nor does it address specific tax considerations that may be relevant to particular persons (including, for example, financial institutions, broker-dealers, taxpayers subject to special tax accounting rules under Section 451(b) of the Internal Revenue Code, insurance companies, partnerships or other pass-through entities (and partners or beneficial owners therein), certain U.S. expatriates or long-term residents, persons that have a "functional currency" other than the U.S. dollar, tax-exempt organizations, pension plans, tax-qualified retirement plans, "qualified foreign pension funds" as defined in Section 897(l)(2) of the Internal Revenue Code and entities all of the interests of which are held by qualified foreign pension funds, "controlled foreign corporations", "passive foreign investment companies", corporations that accumulate earnings to avoid U.S. federal income tax, persons in special situations, such as those who have elected to mark securities to market or those who hold common stock as part of a straddle, hedge, conversion transaction, synthetic security or other integrated investment, or holders subject to the alternative minimum tax). In addition, except as explicitly addressed herein with respect to estate tax, this summary does not address estate and gift tax considerations, the Medicare contribution tax on net investment income, or considerations under the tax laws of any state, local or non-U.S. jurisdiction or any U.S. federal tax laws other than U.S. federal income or estate tax laws.

For purposes of this summary, a "Non-U.S. Holder" means a beneficial owner of common stock that for U.S. federal income tax purposes is not classified as a partnership and that, for U.S. federal income tax purposes, is not:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • an individual who is a citizen or resident of the United States;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • a corporation or any other organization taxable as a corporation for U.S. federal income tax purposes, created or organized in or under the laws of the United States, any state thereof or the District of Columbia;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • an estate, the income of which is included in gross income for U.S. federal income tax purposes regardless of its source; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • a trust if (1) a U.S. court is able to exercise primary supervision over the trust's administration and one or more U.S. persons have the authority to control all of the trust's substantial decisions or (2) the trust has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person.

If an entity that is classified as a partnership for U.S. federal income tax purposes holds our common stock, the tax treatment of persons treated as its partners for U.S. federal income tax purposes will generally depend upon the status of the partner and the activities of the partnership. Partnerships and other entities that are classified as partnerships for U.S. federal income tax purposes and persons holding our common stock through a partnership or other entity classified as a partnership for U.S. federal income tax purposes are urged to consult their own tax advisors.

If you are an individual, you are a resident alien if you are a lawful permanent resident of the United States (e.g., a green card holder) and you may, in many cases, be deemed to be a resident alien, as opposed to a nonresident alien, by virtue of being present in the United States for at least 31 days in the calendar year and for an aggregate of at least 183 days during a three-year period ending in and including the current calendar year. For these purposes, all the days present in the United States in the current year, one-third of

------

[**TABLE OF CONTENTS**](#TOC)

the days present in the immediately preceding year, and one-sixth of the days present in the second preceding year are counted. Resident aliens are subject to U.S. federal income tax as if they are U.S. citizens. Such an individual is urged to consult his or her own tax advisor regarding the U.S. federal income and estate tax consequences of the purchase, ownership or disposition of our common stock.

There can be no assurance that the Internal Revenue Service ("IRS") will not challenge one or more of the tax consequences described herein, and we have not obtained, nor do we intend to obtain a ruling from the IRS with respect to the U.S. federal income or estate tax consequences to a Non-U.S. Holder of the purchase, ownership or disposition of our common stock.

THIS SUMMARY IS FOR GENERAL INFORMATION ONLY AND IS NOT INTENDED TO BE TAX ADVICE. NON-U.S. HOLDERS ARE URGED TO CONSULT THEIR TAX ADVISORS CONCERNING THE U.S. FEDERAL INCOME AND ESTATE TAXATION, STATE, LOCAL AND NON-U.S. TAXATION AND OTHER TAX CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF OUR COMMON STOCK.

#### Distributions on Our Common Stock
In the event that we make a distribution of cash or property with respect to our common stock, any such distributions generally will constitute dividends for U.S. federal income tax purposes to the extent of our current and accumulated earnings and profits, as determined under U.S. federal income tax principles. If a distribution exceeds our current and accumulated earnings and profits, the excess will constitute a return of capital and will first reduce the holder's adjusted tax basis in our common stock, but not below zero. Any remaining excess will be treated as capital gain, subject to the tax treatment described below in "— Gain on Sale, Exchange or Other Taxable Disposition of Our Common Stock." Any such distribution would also be subject to the discussions below under the sections titled "— Additional Withholding and Reporting Requirements" and "— Backup Withholding and Information Reporting."

Dividends paid to a Non-U.S. Holder generally will be subject to a 30% U.S. federal withholding tax unless such Non-U.S. Holder provides us or the applicable withholding agent, as the case may be, with the appropriate IRS Form W-8, such as:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • A valid IRS Form W-8BEN or IRS Form W-8BEN-E (or successor forms) certifying, under penalties of perjury, a reduction in, or exemption from, withholding under an applicable income tax treaty, or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • A valid IRS Form W-8ECI (or successor form) certifying, under penalties of perjury, that a dividend paid on common stock is not subject to withholding tax because it is effectively connected with a trade or business in the United States of the Non-U.S. Holder (in which case such dividend generally will be subject to regular graduated U.S. tax rates as described below).

The certification requirement described above must be provided to us or the applicable withholding agent prior to the payment of dividends and may be required to be updated periodically. The certification also may require a Non-U.S. Holder that provides an IRS form or that claims treaty benefits to provide its U.S. taxpayer identification number. Special certification and other requirements apply in the case of certain Non-U.S. Holders that hold shares of our common stock through intermediaries or are pass-through entities for U.S. federal income tax purposes.

If the Non-U.S. Holder holds the stock through a financial institution or other agent acting on the holder's behalf, the holder will be required to provide appropriate documentation to the agent. Subject to the applicable exceptions, the holder's agent will then be required to provide certification to us or our paying agent, either directly or through other intermediaries. Even if our current or accumulated earnings and profits are less than the amount of the distribution, the applicable withholding agent may elect to treat the entire distribution as a dividend for U.S. federal withholding tax purposes. A Non-U.S. Holder that does not timely furnish the required documentation, but that qualifies for a reduced treaty rate, may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS.

Each Non-U.S. Holder is urged to consult its own tax advisor about the specific methods for satisfying these requirements. A claim for exemption will not be valid if the person receiving the applicable form has actual knowledge or reason to know that the statements on the form are false.

------

[**TABLE OF CONTENTS**](#TOC)

If dividends are effectively connected with a trade or business in the United States of a Non-U.S. Holder (and, if required by an applicable income tax treaty, are attributable to a U.S. permanent establishment or, in certain cases involving individual holders, a fixed base), the Non-U.S. Holder, although exempt from the withholding tax described above (provided that the certification requirements described above are satisfied), generally will be subject to U.S. federal income tax on such dividends on a net income basis in the same manner as if it were a United States person, as defined under the Internal Revenue Code. In addition, if a Non-U.S. Holder is treated as a corporation for U.S. federal income tax purposes, the Non-U.S. Holder may be subject to an additional "branch profits tax" equal to 30% (unless reduced by an applicable income treaty) of its earnings and profits in respect of such effectively connected dividend income.

Non-U.S. Holders that do not timely provide us or the applicable withholding agent with the required certification, but which are eligible for a reduced rate of U.S. federal withholding tax pursuant to an income tax treaty, may obtain a refund or credit of any excess amount withheld by timely filing an appropriate claim for refund with the IRS.

#### Gain on Sale, Exchange or Other Taxable Disposition of Our Common Stock
Subject to the discussions below under the sections titled "— Additional Withholding and Reporting Requirements" and "— Backup Withholding and Information Reporting", in general, a Non-U.S. Holder will not be subject to U.S. federal income tax or withholding tax on gain realized upon such holder's sale, exchange or other taxable disposition of shares of our common stock unless (i) such Non-U.S. Holder is an individual who is present in the United States for 183 days or more in the taxable year of disposition, and certain other conditions are met, (ii) we are or have been a "United States real property holding corporation", as defined in the Internal Revenue Code (a "USRPHC"), at any time within the shorter of the five-year period preceding the disposition and the Non-U.S. Holder's holding period in the shares of our common stock, and certain other requirements are met, or (iii) such gain is effectively connected with the conduct by such Non-U.S. Holder of a trade or business in the United States (and, if required by an applicable income tax treaty, is attributable to a permanent establishment maintained by such Non-U.S. Holder in the United States or, in certain cases involving individual holders, a fixed base).

If the first exception applies, the Non-U.S. Holder generally will be subject to U.S. federal income tax at a rate of 30% (or at a reduced rate under an applicable income tax treaty) on the amount by which such Non-U.S. Holder's capital gains allocable to U.S. sources exceed capital losses allocable to U.S. sources during the taxable year of the disposition. If the third exception applies, the Non-U.S. Holder generally will be subject to U.S. federal income tax with respect to such gain on a net income basis in the same manner as if it were a resident of the United States and a Non-U.S. Holder that is a corporation for U.S. federal income tax purposes may also be subject to a branch profits tax with respect to any earnings and profits attributable to such gain at a rate of 30% (or at a reduced rate under an applicable income tax treaty).

Generally, a corporation is a USRPHC only if the fair market value of its United States real property interests (as defined in the Internal Revenue Code) equals or exceeds 50% of the sum of the fair market value of its worldwide real property interests plus its other assets used or held for use in a trade or business. Although there can be no assurance in this regard, we believe that we are not, and do not anticipate becoming, a USRPHC. However, because the determination of whether we are a USRPHC depends on the fair market value of our United States real property interests relative to the fair market value of other business assets, there can be no assurance that we will not become a USRPHC in the future. Even if we are or were to become a USRPHC, a Non-U.S. Holder would not be subject to U.S. federal income tax on a sale, exchange or other taxable disposition of our common stock by reason of our status as USRPHC so long as our common stock is "regularly traded" (as defined by applicable Treasury regulations) on an established securities market at any time during the calendar year in which the disposition occurs and such Non-U.S. Holder does not own and is not deemed to own (directly, indirectly or constructively) more than 5% of our common stock at any time during the shorter of the five-year period ending on the date of disposition and the holder's holding period. However, no assurance can be provided that our common stock will be regularly traded on an established securities market for purposes of the rules described above. Prospective investors are encouraged to consult their own tax advisors regarding the possible consequences to them if we are, or were to become, a USRPHC.

[**TABLE OF CONTENTS**](#TOC)

#### Additional Withholding and Reporting Requirements
Sections 1471 through 1474 of the Internal Revenue Code and the related Treasury regulations, together with other U.S. Treasury and IRS guidance issued thereunder and intergovernmental agreements, legislation, rules and other official guidance adopted pursuant to such intergovernmental agreements (collectively, "FATCA") generally impose U.S. federal withholding at a rate of 30% on payments of dividends on our common stock paid to (i) a "foreign financial institution" (as specifically defined in the Internal Revenue Code) which does not provide sufficient documentation, typically on IRS Form W-8BEN-E, evidencing either (x) an exemption from FATCA or (y) its compliance (or deemed compliance) with FATCA (which may alternatively be in the form of compliance with an intergovernmental agreement with the United States) in a manner which avoids withholding, or (ii) a "non-financial foreign entity" (as specifically defined in the Internal Revenue Code) which does not provide sufficient documentation, typically on IRS Form W-8BEN-E, evidencing either (x) an exemption from FATCA or (y) adequate information regarding certain substantial United States beneficial owners of such entity (if any). An intergovernmental agreement between the U.S. and an applicable foreign country may, however, modify these requirements. If FATCA withholding is imposed, a beneficial owner that is not a foreign financial institution generally will be entitled to a refund of any amounts withheld by filing a U.S. federal income tax return containing the required information (which may entail significant administrative burden). Non-U.S. Holders are urged to consult their own tax advisors regarding the effects of FATCA on their investment in our common stock.

While withholding under FATCA would have applied to payments of gross proceeds from the sale or other disposition of stock on or after January 1, 2019 by such applicable non-U.S. entities, proposed Treasury regulations (on which taxpayers and withholding agents may currently rely) eliminate FATCA withholding on payments of gross proceeds from the sale or other disposition of stock entirely. Taxpayers and withholding agents generally may rely on these proposed Treasury regulations until final Treasury regulations are issued.

Prospective investors should consult their own tax advisors regarding the possible impact of these rules on their investment in our common stock, and the entities through which they hold our common stock, including, without limitation, the process and deadlines for meeting the applicable requirements to prevent the imposition of this 30% withholding tax under FATCA.

#### Backup Withholding and Information Reporting
In general, information reporting will apply to distributions on our common stock paid to a Non-U.S. Holder and the tax withheld, if any, with respect to the distributions. Non-U.S. Holders may have to comply with specific certification procedures to establish that the holder is not a United States person (as defined in the Internal Revenue Code) in order to avoid backup withholding at the applicable rate, currently 24%, with respect to dividends on our common stock. A Non-U.S. Holder will not be subject to backup withholding on dividends received if such holder certifies under penalty of perjury that it is a Non-U.S. Holder (and the payor does not have actual knowledge or reason to know that such holder is a United States person as defined under the Internal Revenue Code), or such holder otherwise establishes an exemption. Provision of an IRS Form W-8 appropriate to the Non-U.S. Holder's circumstances will generally satisfy the certification requirements necessary to avoid the additional information reporting and backup withholding.

Information reporting and, depending on the circumstances, backup withholding will generally apply to the proceeds of a disposition of our common stock by a Non-U.S. Holder effected by or through the U.S. office of any broker, U.S. or foreign, unless the holder certifies its status as a Non-U.S. Holder and satisfies certain other requirements, or otherwise establishes an exemption. Generally, information reporting and backup withholding will not apply to a payment of disposition proceeds to a Non-U.S. Holder where the transaction is effected outside the United States through a non-U.S. office of a broker. However, for information reporting purposes, dispositions effected through a non-U.S. office of a U.S. broker or a foreign broker with substantial U.S. ownership or operations generally will be treated in a manner similar to dispositions effected through a U.S. office of a broker. Prospective investors should consult their own tax advisors regarding the application of the information reporting and backup withholding rules to them.

Copies of information returns may be made available to the tax authorities of the country in which the Non-U.S. Holder resides or in which the Non-U.S. Holder is incorporated, under the provisions of a specific treaty or agreement.

------

[**TABLE OF CONTENTS**](#TOC)

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules from a payment to a Non-U.S. Holder may be refunded or credited against the Non-U.S. Holder's U.S. federal income tax liability, if any, provided that an appropriate claim is timely filed with the IRS.

#### Federal Estate Tax
Shares of our common stock that are owned (or treated as owned) by an individual who is not a citizen or resident of the United States (as specially defined for U.S. federal estate tax purposes) at the time of such individual's death will be included in such individual's gross estate for U.S. federal estate tax purposes, unless an applicable estate or other tax treaty provides otherwise, and therefore may be subject to U.S. federal estate tax.

Under the terms and subject to the conditions in an underwriting agreement dated the date of this prospectus supplement, Goldman Sachs & Co. LLC, as underwriter, has agreed to purchase, and the selling stockholders have agreed to sell to the underwriter, 16,000,000 shares of our common stock.

The underwriting agreement provides that the obligations of the underwriter to purchase the shares included in this offering are subject to approval of legal matters by counsel and to other conditions. The underwriter is obligated to purchase all the shares (other than those covered by the underwriter's option to purchase additional shares described below) if it purchases any of the shares.

#### Commissions and Discounts
Shares sold by the underwriter to the public will initially be offered at the public offering price set forth on the cover of this prospectus supplement. Any shares sold by the underwriter to securities dealers may be sold at a discount from the public offering price not to exceed $ per share. If all the shares are not sold at the public offering price, the underwriter may change the public offering price and the other selling terms. The offering of the shares by the underwriter is subject to receipt and acceptance and subject to the underwriter's right to reject any order in whole or in part.

The underwriter may offer and sell the shares to the public through one or more of its affiliates or other registered broker-dealers or selling agents.

The selling stockholders have granted to the underwriter an option, exercisable for 30 days from the date of this prospectus supplement, to purchase up to 2,400,000 additional shares at the public offering price less the underwriting discount. To the extent the option is exercised, the underwriter must purchase a number of additional shares approximately proportionate to the underwriter's initial purchase commitment. Any shares issued or sold under the option will be issued and sold on the same terms and conditions as the other shares that are the subject of this offering.

We, our officers and directors and the selling stockholders have agreed that, for a period of 30 days from the date of this prospectus supplement, we and they will not, without the prior written consent of the underwriter, dispose of or hedge any shares or any securities convertible into or exchangeable for our common stock, subject to certain exceptions.

Our common stock is listed on the New York Stock Exchange under the symbol "HAYW."

The following table shows the underwriting discounts and commissions that the selling stockholders are to pay to the underwriter in connection with this offering. These amounts are shown assuming both no exercise and full exercise of the underwriter's option to purchase additional shares described above:

---

| | | | |
|:---|:---|:---|:---|
| | **Per Share**  | **Total <br> (No Exercise)**  | **Total <br> (Full Exercise)**  |
| Public offering price  |  | $&nbsp;&nbsp;&nbsp; | $&nbsp;&nbsp;&nbsp; |
| Underwriting discount to be paid by the selling stockholders  |  | $&nbsp;&nbsp;&nbsp; | $&nbsp;&nbsp;&nbsp; |
| Proceeds, before expenses, to the selling stockholders  |  | $&nbsp;&nbsp;&nbsp; | $&nbsp;&nbsp;&nbsp; |

---

The expenses of the offering, including expenses incurred by the selling stockholders but not including the underwriting discount, are estimated at $1.2 million and are payable by us. We have agreed to reimburse the underwriter for expenses relating to review by the Financial Industry Regulatory Authority up to $10,000.00.

In connection with the offering, the underwriter may purchase and sell shares in the open market. Purchases and sales in the open market may include short sales, purchases to cover short positions, which may include purchases pursuant to the underwriter's option to purchase additional shares, and stabilizing purchases.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Short sales involve secondary market sales by the underwriter of a greater number of shares than it is required to purchase in the offering.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • "Covered" short sales are sales of shares in an amount up to the number of shares represented by the underwriter's option to purchase additional shares.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • "Naked" short sales are sales of shares in an amount in excess of the number of shares represented by the underwriter's option to purchase additional shares.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Covering transactions involve purchases of shares either pursuant to the underwriter's option to purchase additional shares or in the open market in order to cover short positions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • To close a naked short position, the underwriter must purchase shares in the open market. A naked short position is more likely to be created if the underwriter is concerned that there may be downward pressure on the price of the shares in the open market after pricing that could adversely affect investors who purchase in the offering.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • To close a covered short position, the underwriter must purchase shares in the open market or must exercise the option to purchase additional shares. In determining the source of shares to close the covered short position, the underwriter will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which it may purchase shares through the underwriter's option to purchase additional shares.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Stabilizing transactions involve bids to purchase shares so long as the stabilizing bids do not exceed a specified maximum.

Purchases to cover short positions and stabilizing purchases, as well as other purchases by the underwriter for its own account, may have the effect of preventing or retarding a decline in the market price of the shares. They may also cause the price of the shares to be higher than the price that would otherwise exist in the open market in the absence of these transactions. The underwriter may conduct these transactions on the New York Stock Exchange, in the over-the-counter market or otherwise. If the underwriter commences any of these transactions, it may discontinue them at any time.

#### Relationships
The underwriter is a full service financial institution engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, principal investment, hedging, financing and brokerage activities. The underwriter and its affiliates have in the past performed commercial banking, investment banking and advisory services for us from time to time for which they have received customary fees and reimbursement of expenses and may, from time to time, engage in transactions with and perform services for us in the ordinary course of their business for which they may receive customary fees and reimbursement of expenses. In the ordinary course of their various business activities, the underwriter and its affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (which may include bank loans and/or credit default swaps) for their own account and for the accounts of their customers and may at any time hold long and short positions in such securities and instruments. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. The underwriter and its affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments. For example, affiliates of the underwriter also serve as lenders under our debt facilities.

We have agreed to indemnify the underwriter against certain liabilities, including liabilities under the Securities Act, or to contribute to payments the underwriter may be required to make because of any of those liabilities.

#### ABOUT THIS PROSPECTUS
This prospectus is a part of a registration statement on Form S-3 that we filed with the Securities and Exchange Commission (the "Commission"), as a "well-known seasoned issuer" as defined under Rule 405 under the Securities Act of 1933, as amended (the "Securities Act") using a "shelf" registration process. Under this shelf registration process, the selling stockholders may, on a continuous basis, in one or more offerings, sell or otherwise dispose of shares of our Common Stock.

This prospectus incorporates by reference important business and financial information about us that is not included in or delivered with this document. Each time securities are sold under the shelf registration statement, we will provide a prospectus supplement that will contain specific information about the terms of those securities and the terms of that offering. The prospectus supplement may also add, update or change information contained in this prospectus. If there is any inconsistency between the information in this prospectus and any prospectus supplement, you should rely on the information in the prospectus supplement. You should read both this prospectus and any prospectus supplement, including all documents incorporated by reference herein and therein, together with the additional information described under "Where You Can Find More Information" below.

We will not receive any proceeds from the sale or other disposition of the shares of our Common Stock by the selling stockholders.

The information contained in this prospectus may not be complete and may be changed. You should rely only on the information provided in or incorporated by reference in this prospectus or in any prospectus supplement, or documents to which we otherwise refer you.

#### FORWARD-LOOKING STATEMENTS
This prospectus and the documents that we incorporate by reference in the prospectus contain statements that are considered "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended (the "Securities Act"), and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Forward-looking statements, including statements about industry trends and other matters that do not relate strictly to historical facts, are based on management's expectations and assumptions, and are often identified by such forward-looking terminology as "expect," "look," "believe," "anticipate," "estimate," "seek," "may," "trend," "target," and "goal" or similar statements or variations of such terms. Forward-looking statements may include, among other things, statements regarding:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • projections of revenue, margins, expenses, earnings from operations, cash flows or other financial items;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • plans, strategies and objectives of management for future operations, including statements relating to developments or performance of our products;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • future economic conditions or performance;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the outcome of outstanding claims or legal proceedings;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • assumptions underlying any of the foregoing;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • any other statements that address activities, events or developments that we intend, expect, project, believe or anticipate will or may occur in the future; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • statements described under the heading "Cautionary Statement Regarding Forward Looking Statements" in our [Annual Report on Form 10-K for the year ended December 31, 2021 (our "Form 10-K")](http://www.sec.gov/ix?doc=/Archives/edgar/data/1834622/000183462222000024/hayw-20211231.htm) and the heading "Special Note Regarding Forward Looking Statements" in our Quarterly Report on Form 10-Q for the period ended April 2, 2022, which are hereby incorporated herein by reference.

Forward-looking statements are subject to various risks and uncertainties, which change over time, are based on management's expectations and assumptions at the time the statements are made, and are not guarantees of future results. Our management's expectations and assumptions, and the continued validity of the forward-looking statements, are subject to change due to a broad range of factors affecting the national and global economies, the financial markets, as well as factors specific to us and our subsidiaries, as discussed under the heading "Risk Factors" in our Form 10-K and Form 10-Qs and other filings with the SEC and incorporated into this prospectus by reference.

Actual outcomes and results may differ materially from what is expressed in our forward-looking statements and from our historical financial results due to the factors discussed above and elsewhere in this prospectus, including, without limitation, our Form 10-K and Form 10-Qs, or in our other SEC filings. Forward-looking statements should not be relied upon as representing our expectations or beliefs as of any time subsequent to the time this prospectus is filed with the SEC. Unless specifically required by law, we undertake no obligation to revise the forward-looking statements contained in this prospectus to reflect events after the time it is filed with the SEC. The factors discussed above are not intended to be a complete summary of all risks and uncertainties that may affect our businesses. Though we strive to monitor and mitigate risk, we cannot anticipate all potential economic, operational and financial developments that may adversely affect our operations and our financial results.

Forward-looking statements should not be viewed as predictions, and should not be the primary basis upon which investors evaluate us. Any of our investors should consider all risks and uncertainties disclosed in our SEC filings, described under the section entitled "Where You Can Find More Information," all of which are accessible on the SEC's website at http://www.sec.gov. We note that all website addresses given in this prospectus are for information only and are not intended to be an active link or to incorporate any website information into this document.

#### PLAN OF DISTRIBUTION
The selling stockholders may sell the securities offered hereby in one or more of the following ways (or in any combination thereof) from time to time:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • to or through underwriters, agents, brokers or dealers, who may receive compensation in the form of underwriting discounts, concessions or commissions from the selling stockholders and/or the purchasers of the securities for whom they may act as agent;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • in one or more block transactions, including transactions in which the broker or dealer so engaged will attempt to sell the securities as agent but may position and resell a portion of the block as principal to facilitate the transaction, or in crosses, in which the same broker acts as an agent on both sides of the trade;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • through purchases by a broker-dealer or market maker, as principal, and resale by the broker-dealer for its account;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • through "at the market" offering transactions into an existing market for the common stock;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • through the pledge of the securities for any loan or obligation, including pledges to brokers or dealers who may from time to time effect distributions of shares of our Common Stock or other of our securities and, in the case of any collateral call, default or foreclosure on such loan or obligation, pledges or sales of shares of our Common Stock or other of our securities by such pledgees or secured parties;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • through short sales or transactions to cover short sales relating to the securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • in one or more exchange or over the counter market transactions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • through the distribution by the selling stockholders or any of their respective successors in interest to their members, general or limited partners or shareholders (or their respective members, general or limited partners or shareholders);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • in privately negotiated transactions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • through the writing of options, whether the options are listed on an options exchange or otherwise;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • through delivery of shares upon conversion, exchange, exercise or other settlement of other securities or debt instruments (whether such other securities or debt instruments are issued by the selling stockholder or any other party);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • through distributions to creditors and equity holders of the selling stockholders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • directly to purchasers, including through a specific bidding, auction or other process (including, without limitation, in privately negotiated transactions);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • in off market transactions at prevailing market prices;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • through a combination of such methods; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • through any other method permitted by applicable law.

The selling stockholders may also sell all or a portion of their securities pursuant to Rule 144 or another exemption from registration under the Securities Act, if available, in transactions not covered by this prospectus.

The selling stockholders may enter into sale, forward sale, derivative or other similar transactions with third parties. In connection with any sale, forward sale, derivative or other similar transactions with third parties, the third parties (or underwriters on their behalf) may sell shares of our Common Stock or other of our securities, including in short sale transactions and by issuing securities that are not covered by this prospectus but are exchangeable, convertible, exercisable or may represent beneficial interests in or otherwise be settled for our Common Stock. The third parties also may use shares or other securities received under those sale, forward sale or derivative arrangements or shares or other securities pledged by a selling stockholder or borrowed from a selling stockholder or others to settle such third-party sales or to close out any related open borrowings of our Common Stock or other securities. The third parties or underwriters selling shares of

------

[**TABLE OF CONTENTS**](#TOC2)

our Common Stock or other securities on their behalf may deliver this prospectus in connection with any such transactions. Any third party in such sale transactions may be an underwriter and, if required, will be identified in a prospectus supplement.

In addition, the selling stockholders may also enter into option or other transactions with broker-dealers or other financial institutions, which may require the delivery of securities to the broker-dealer or other financial institution. The broker-dealer may then resell or otherwise transfer such securities pursuant to this prospectus. The selling stockholders also may loan or pledge securities, and the borrower or pledgee may sell or otherwise transfer the securities so loaned or pledged pursuant to this prospectus. Such borrower or pledgee also may transfer those securities to investors in our securities or another selling stockholder's securities or in connection with the offering of other securities not covered by this prospectus.

To the extent necessary, a prospectus supplement will describe any additional terms of an offering of the shares of our Common Stock, including, to the extent applicable, the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the name or names of any underwriters, dealers or agents and the amount of shares of our Common Stock underwritten or purchased by each of them;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • any offering price and any discounts or concessions allowed or reallowed or paid to dealers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the public offering price of the shares of our Common Stock, the proceeds to the selling stockholders, and any discounts, commissions or concessions allowed or reallowed or paid to underwriters, dealers or agents, and other items constituting underwriters', dealers' or agents' compensation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • any delayed delivery arrangements; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • information about the selling stockholders, including the relationship between the selling stockholders and us.

The selling stockholders may, or may authorize underwriters, dealers or other persons acting as our agents, to solicit offers by certain institutions to purchase securities from the selling stockholders pursuant to delayed delivery contracts providing for payment and delivery on the date stated in each applicable prospectus supplement. If necessary, any such contracts will be described in, and be subject to the conditions set forth in, a supplement to this prospectus.

Broker-dealers or agents may receive compensation in the form of commissions, discounts or concessions from the selling stockholders. Broker-dealers or agents may also receive compensation from the purchasers of securities for whom they act as agents or to whom they sell as principals, or both. Compensation to a particular broker-dealer might be in excess of customary commissions and will be in amounts to be negotiated in connection with transactions involving securities. In effecting sales, broker-dealers engaged by the selling stockholders may arrange for other broker-dealers to participate in the resales.

We and the selling stockholders have agreed to indemnify each other against certain liabilities, including liabilities under the Securities Act. In addition, agents, underwriters and other third parties described above may be entitled to indemnification by us and the selling stockholders against certain civil liabilities, including liabilities under the Securities Act, or to contribution from us and the selling stockholders with respect to payments which the agents, underwriters or third parties may be required to make in respect thereof. Agents, underwriters and such other third parties may be customers of, engage in transactions with, or perform services for us or the selling stockholders in the ordinary course of business. We and the selling stockholders may also use underwriters or such other third parties with whom we or such selling stockholders have a material relationship. We and the selling stockholders will describe the nature of any such relationship in the applicable prospectus supplement.

Certain underwriters may use this prospectus and any accompanying prospectus supplement for offers and sales related to market-making transactions in our Common Stock. These underwriters may act as principal or agent in these transactions, and the sales will be made at prices related to prevailing market prices at the time of sale. Any underwriters involved in the sale of our Common Stock may qualify as "underwriters" within the meaning of Section 2(a)(11) of the Securities Act. Accordingly, any profits realized by a selling stockholder and any compensation earned by any such underwriter, broker-dealer or agent may be deemed to be underwriting commissions, discounts or concessions and may qualify as

------

[**TABLE OF CONTENTS**](#TOC2)

underwriters' compensation under the Securities Act and the rules of the Financial Industry Regulatory Authority. Persons who are "underwriters" under the Securities Act with respect to the securities offered hereby must comply with any applicable prospectus delivery requirements under the Securities Act. In addition, Regulation M may restrict the ability of any person engaged in the distribution of the securities offered hereby to engage in market-making or other activities with respect to the securities.

In order to comply with applicable securities laws of some states or countries, the securities may only be sold in those jurisdictions through registered or licensed brokers or dealers and in compliance with applicable laws and regulations. In addition, in certain states or countries the securities may not be sold unless they have been registered or qualified for sale in the applicable state or country or an exemption from the registration or qualification requirements is available.

Our Common Stock is listed on The New York Stock Exchange. Underwriters may make a market our Common Stock, but will not be obligated to do so and may discontinue any market making at any time without notice. We can make no assurance as to the development, maintenance or liquidity of any trading market in our Common Stock.

Certain persons participating in an offering may engage in overallotment, stabilizing transactions, short covering transactions and penalty bids in accordance with rules and regulations under the Exchange Act. Overallotment involves sales in excess of the offering size, which create a short position. Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum. Short covering transactions involve purchases of our Common Stock in the open market after the distribution is completed to cover short positions. Penalty bids permit the underwriters to reclaim a selling concession from a dealer when the shares of our Common Stock originally sold by the dealer are purchased in a covering transaction to cover short positions. Those activities may stabilize, maintain or otherwise affect the market price of the securities offered under this prospectus. As a result, the price of the shares of our Common Stock may be higher than it would otherwise be. If commenced, the underwriters may discontinue any of the activities at any time. These transactions may be effected on the NYSE or another securities exchange or automated quotation system, or in the over-the-counter market or otherwise.

#### DESCRIPTION OF CAPITAL STOCK
The total amount of our authorized capital stock consists of 750,000,000 shares of common stock, par value $0.001 per share and 100,000,000 shares of undesignated preferred stock.

As of April 29, 2022 we have 226,482,635 shares of common stock and no shares of preferred stock outstanding. The following summary describes all material provisions of our capital stock. We urge you to read our second restated certificate of incorporation and amended and restated bylaws, the forms of which are filed as exhibits to the registration statement of which this prospectus is a part.

Our second restated certificate of incorporation and amended and restated bylaws contain provisions that are intended to enhance the likelihood of continuity and stability in the composition of the Board of Directors and which may have the effect of delaying, deferring or preventing a future takeover or change in control of our company unless such takeover or change in control is approved by our Board of Directors. These provisions include a classified board of directors, elimination of the ability of stockholders to call special meetings (except that the holders of 50% or more of the outstanding shares of our common stock may request that the Corporate Secretary call special meetings so long as the Sponsors beneficially own a majority of the outstanding shares of our common stock), advance notice procedures for stockholder proposals and the ability of our Board of Directors to issue preferred stock without stockholder approval that could be used to dilute a potential hostile acquiror.

#### Common Stock
*Dividend Rights*. Subject to preferences that may apply to shares of preferred stock outstanding at the time, holders of outstanding shares of our common stock are entitled to receive dividends out of assets legally available at the times and in the amounts as the Board of Directors may from time to time determine.

*Voting Rights*. Each outstanding share of our common stock is entitled to one vote on all matters submitted to a vote of stockholders. Holders of shares of our common stock have no cumulative voting rights.

*Preemptive Rights*. Our common stock is not entitled to preemptive or other similar subscription rights to purchase any of our securities.

*Conversion or Redemption Rights.* Our common stock does not have any conversion rights and there are no redemption or sinking fund provisions applicable to our common stock.

*Liquidation Rights.* Upon our liquidation, the holders of our common stock will be entitled to receive pro rata our assets that are legally available for distribution, after payment of all debts and other liabilities and subject to the prior rights of any holders of preferred stock then outstanding*.* 

*Listing*. Our common stock is listed on the New York Stock Exchange under the symbol "HAYW."

*Transfer Agent and Registrar*. The transfer agent and registrar for our common stock is American Stock Transfer & Trust Company, LLC. Its address is 6201 15th Avenue, Brooklyn, NY 11219. Its telephone number is (800) 937-5449.

#### Preferred Stock
Our second restated certificate of incorporation authorizes our Board of Directors to establish one or more series of preferred stock (including convertible preferred stock). Our Board of Directors may, without

------

[**TABLE OF CONTENTS**](#TOC2)

further action by our stockholders, from time to time, direct the issuance of shares of preferred stock in series and may, at the time of issuance, determine the designations, powers, preferences, privileges, and relative participating, optional or special rights as well as the qualifications, limitations or restrictions thereof, including dividend rights, conversion rights, voting rights, terms of redemption and liquidation preferences, any or all of which may be greater than the rights of the common stock. Satisfaction of any dividend preferences of outstanding shares of preferred stock would reduce the amount of funds available for the payment of dividends on shares of our common stock. Holders of shares of preferred stock may be entitled to receive a preference payment in the event of our liquidation before any payment is made to the holders of shares of our common stock. Under certain circumstances, the issuance of shares of preferred stock may render more difficult or tend to discourage a merger, tender offer or proxy contest, the assumption of control by a holder of a large block of our securities or the removal of incumbent management. Upon the affirmative vote of a majority of the total number of directors then in office, our Board of Directors, without stockholder approval, may issue shares of preferred stock with voting and conversion rights which could adversely affect the holders of shares of our common stock and the market value of our common stock. Upon consummation of this offering, there will be no shares of preferred stock outstanding, and we have no present intention to issue any shares of preferred stock.

#### Anti-Takeover Effects of Our Second Restated Certificate of Incorporation and Amended and Restated Bylaws and Certain Provisions of Delaware Law
Our second restated certificate of incorporation and amended and restated bylaws contain certain provisions that are intended to enhance the likelihood of continuity and stability in the composition of the Board of Directors and which may have the effect of delaying, deferring or preventing a future takeover or change in control of the company unless such takeover or change in control is approved by the Board of Directors. These provisions include:

*Classified Board*. Our second restated certificate of incorporation provides that our Board of Directors will be divided into three classes of directors, with the classes as nearly equal in number as possible. As a result, approximately one-third of our Board of Directors will be elected each year. The classification of directors will have the effect of making it more difficult for stockholders to change the composition of our board. Our second restated certificate of incorporation also provides that, subject to any rights of holders of preferred stock to elect additional directors under specified circumstances, the number of directors will be fixed exclusively pursuant to a resolution adopted by our Board of Directors. Our Board of Directors currently has, and upon completion of this offering, will continue to have thirteen members.

*Special Meetings of Stockholders*. Our second restated certificate of incorporation and amended and restated bylaws provide that, except as otherwise required by law, special meetings of the stockholders may be called only (i) by our chairperson of the Board of Directors, (ii) by a resolution adopted by a majority of our Board of Directors, or (iii) by our Corporate Secretary at the request of the holders of 50% or more of the outstanding shares of our common stock so long as the Sponsors beneficially own a majority of the outstanding shares of our common stock.

*Removal of Directors*. Our second restated certificate of incorporation provides that, so long as the Sponsors beneficially own a majority of the outstanding shares of our common stock, our directors may be removed only for cause by the affirmative vote of a majority of the voting power of our outstanding shares of capital stock entitled to vote generally in the election of directors, voting together as a single class. Following the date on which the Sponsors no longer beneficially own a majority of the outstanding shares of our common stock, no member of our Board of Directors may be removed from office except for cause by the affirmative vote of the holders of at least seventy-five percent (75%) of the voting power of our outstanding shares of capital stock entitled to vote thereon.

*Elimination of Stockholder Action by Written Consent*. Our second restated certificate of incorporation eliminates the right of stockholders to act by written consent without a meeting following the date on which the Sponsors no longer beneficially own a majority of the outstanding shares of our common stock.

*Advance Notice Procedures*. Our amended and restated bylaws establishes an advance notice procedure for stockholder proposals to be brought before an annual meeting of our stockholders, including proposed

------

[**TABLE OF CONTENTS**](#TOC2)

nominations of persons for election to the Board of Directors. Stockholders at an annual meeting will only be able to consider proposals or nominations specified in the notice of meeting or brought before the meeting by or at the direction of the Board of Directors or by a stockholder who was a stockholder of record on the record date for the meeting, who is entitled to vote at the meeting and who has given our Corporate Secretary timely written notice, in proper form, of the stockholder's intention to bring that business before the meeting. Although the bylaws do not give the Board of Directors the power to approve or disapprove stockholder nominations of candidates or proposals regarding other business to be conducted at a special or annual meeting, the bylaws may have the effect of precluding the conduct of certain business at a meeting if the proper procedures are not followed or may discourage or deter a potential acquiror from conducting a solicitation of proxies to elect its own slate of directors or otherwise attempting to obtain control of the company.

*Authorized but Unissued Shares*. Our authorized but unissued shares of common stock and preferred stock will be available for future issuance without stockholder approval. These additional shares may be utilized for a variety of corporate purposes, including future public offerings to raise additional capital, corporate acquisitions and employee benefit plans. The existence of authorized but unissued shares of common stock and preferred stock could render more difficult or discourage an attempt to obtain control of a majority of our common stock by means of a proxy contest, tender offer, merger or otherwise.

*Business Combinations with Interested Stockholders*. We have elected in our second restated certificate of incorporation not to be subject to Section 203 of the DGCL, an antitakeover law. In general, Section 203 prohibits a publicly held Delaware corporation from engaging in a business combination, such as a merger, with a person or group owning 15% or more of the Company's voting stock for a period of three years following the date the person became an interested stockholder, unless (with certain exceptions) the business combination or the transaction in which the person became an interested stockholder is approved in a prescribed manner. Accordingly, we are not subject to any anti-takeover effects of Section 203. However, our second restated certificate of incorporation contains provisions that have the same effect as Section 203, except that they provide that the Sponsors and their respective successors, transferees and affiliates will not be deemed to be "interested stockholders," regardless of the percentage of our voting stock owned by them, and accordingly will not be subject to such restrictions.

*Choice of Forum*. Our second restated certificate of incorporation provides that, subject to limited exceptions, the Court of Chancery of the State of Delaware (or, if, and only if, the Court of Chancery of the State of Delaware dismisses a Covered Claim (as defined below) for lack of subject matter jurisdiction, any other state or federal court in the State of Delaware that does have subject matter jurisdiction) will, to the fullest extent permitted by applicable law, be the sole and exclusive forum for the following types of claims: (i) any derivative claim brought in the right of the Company, (ii) any claim asserting a breach of a fiduciary duty to the Company or the Company's stockholders owed by any current or former director, officer or other employee or stockholder of the Company, (iii) any claim against the Company arising pursuant to any provision of the DGCL, our second restated certificate of incorporation or amended and restated bylaws, (iv) any claim to interpret, apply, enforce or determine the validity of our second restated certificate of incorporation or our amended and restated bylaws, (v) any claim against the

Our second restated certificate of incorporation further provides that the federal district courts of the United States of America will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act. In addition, our second restated certificate of incorporation provides that any person or entity purchasing or otherwise acquiring any interest in the shares of capital stock of the Company will be deemed to have notice of and consented to these choice-of-forum provisions and waived any argument relating to the inconvenience of the forums in connection with any Covered Claim.

The choice of forum provisions contained in our second restated certificate of incorporation may limit a stockholder's ability to bring a claim in a judicial forum that it finds favorable for disputes with us or any

------

[**TABLE OF CONTENTS**](#TOC2)

of our directors, officers, other employees or stockholders, which may discourage lawsuits with respect to such claims, although our stockholders will not be deemed to have waived our compliance with federal securities laws and the rules and regulations thereunder. While the Delaware courts have determined that such choice of forum provisions are facially valid, it is possible that a court of law in another jurisdiction could rule that the choice of forum provisions contained in our second restated certificate of incorporation are inapplicable or unenforceable if they are challenged in a proceeding or otherwise, which could cause us to incur additional costs associated with resolving such action in other jurisdictions.

*Amendment of Charter Provisions and Bylaws*. The amendment of any of the above provisions, following the date on which the Sponsors no longer beneficially own a majority of the outstanding shares of our common stock, except for the provision making it possible for our Board of Directors to issue preferred stock, would require the affirmative vote of the holders of at least seventy-five percent (75%) of the voting power of our outstanding shares of capital stock entitled to vote thereon.

The provisions of Delaware law, our second restated certificate of incorporation and our amended and restated bylaws could have the effect of discouraging others from attempting hostile takeovers and, as a consequence, they may also inhibit temporary fluctuations in the market price of our common stock that often result from actual or rumored hostile takeover attempts. These provisions may also have the effect of preventing changes in the composition of our board and management. It is possible that these provisions could make it more difficult to accomplish transactions that stockholders may otherwise deem to be in their best interests.

*Corporate Opportunities.* Our second restated certificate of incorporation provides that we renounce any interest or expectancy in the business opportunities of the Sponsors and all of their respective partners, principals, directors, officers, members, managers and/or employees, including any of the foregoing who serve as directors of the Company, and each such party shall not have any obligation to offer us those opportunities.

*Limitations on Liability and Indemnification of Officers and Directors.* Our second restated certificate of incorporation limits the liability of our directors to the fullest extent permitted by the DGCL or any other law of the state of Delaware and our bylaws provide that we may indemnify our directors and our officers that are appointed by the Board of Directors to the fullest extent permitted by applicable law. We have entered into indemnification agreements with our current directors and executive officers.
