S-2

These forward-looking statements represent management’s expectations as of the date they are made. These forward-looking statements are based on certain assumptions and analyses that we made in light of our experience and our perception of historical trends, current conditions and expected future developments, as well as other factors we believe are appropriate in the circumstances. However, these forward-looking statements are subject to a number of risks and uncertainties and actual results may differ materially from those expressed or implied in such statements. Important factors that could cause actual results, level of activity, performance or achievements to differ materially from those expressed or implied by these forward-looking statements include, among other things, risks related to:

S-3

These forward-looking statements are based on management’s estimates and assumptions with respect to future events and financial performance and are believed to be reasonable, though they are inherently uncertain and difficult to predict.

RISK FACTORS

Before deciding to invest in our Common Stock, you should consider carefully the following discussion of risks and uncertainties affecting us and our Common Stock, as well as the risks and uncertainties incorporated by reference in this prospectus supplement and the accompanying prospectus from our Annual Report on Form 10-K for the fiscal year ended December 31, 2023, as filed with the SEC on February 28, 2024 and the other information contained or incorporated by reference in this prospectus supplement. If any of the events anticipated by these risks and uncertainties occur, our business, financial condition and results of operations could be materially and adversely affected, and the value of our Common Stock could decline. The risks and uncertainties we discuss in this prospectus supplement and the accompanying prospectus and in the documents incorporated by reference herein and therein are those that we currently believe may materially affect our company. Additional risks and uncertainties not presently known to us or that we currently deem immaterial also may materially and adversely affect our business, financial condition and results of operations. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of certain factors. See “Special Note Regarding Forward-Looking Statements” for more information relating to these factors.

Risk Related to our Common Stock and this Offering

We operate as a holding company and our principal source of operating cash is income received from our subsidiaries.

We have a holding company structure and do not have any material assets or operations other than ownership of equity interests of our subsidiaries. Our operations are conducted almost entirely through our subsidiaries, and our ability to generate cash to meet our obligations or to pay dividends is highly dependent on the earnings of, and receipt of funds from, our subsidiaries through dividends or intercompany loans. As a result, we are dependent on the income generated by our subsidiaries to meet our expenses and operating cash requirements. The amount of distributions and dividends, if any, which may be paid from the Company and its subsidiaries to us will depend on many factors, including the Company’s results of operations and consolidated financial condition, its constitutional documents, documents governing any indebtedness of the Company, limits on dividends under applicable law, and other factors which may be outside of our control. If our subsidiaries are unable to generate sufficient cash flow, we may be unable to pay our expenses or make distributions and dividends on the Common Stock. In addition, to the extent we intend to pay dividends on our Common Stock, we will pay such dividends at such times (if any) and in such amounts (if any) as our Board of Directors determines appropriate and in accordance with applicable law and in accordance with restrictions included in the Credit Agreement governing our term loan facility and secured revolving credit facility and in the indentures governing our outstanding senior notes. Payments of such dividends will be dependent on the generation of sufficient cash flow from operations to fund any potential dividend payment. We can therefore give no assurance that we will be able to pay dividends going forward or as to the amount of such dividends, if any.

We have equity instruments outstanding that would require us to issue additional shares of Common Stock. Therefore, you may experience significant dilution of your ownership interests and the future issuance of additional shares of our Common Stock, or the anticipation of such issuances, could have an adverse effect on our stock price.

We have 4,000,000 shares of Series A Preferred Stock outstanding, which are convertible into shares of our Common Stock, at any time at the option of the holder. We are obligated to pay dividends on the 4,000,000 outstanding shares of Series A Preferred Stock based on the market price of our Common Stock if such market price exceeds certain trading price minimums. These dividends are payable in cash or shares of our common stock, at our sole option (which we intend to settle in shares). The issuance of Common Stock pursuant to the terms of the Series A Preferred Stock will reduce (by the applicable proportion) the percentage stockholdings of those stockholders holding Common Stock prior to such issuance which may reduce your net return on your investment in our Common Stock.

In addition, we have various outstanding equity awards to employees and directors under the 2019 Plan. As of December 31, 2023, we had 125,000 shares of Common Stock issuable upon exercise of outstanding stock options, an aggregate of 2,969,725 shares of common stock underlying outstanding RSUs and PSUs (assuming target level) issued under the 2019 Plan, 12,625,337 shares of Common Stock available for issuance under the 2019 Plan and 6,012,500 shares of Common Stock available under the 2020 ESPP.

S-10

We may also issue additional shares of our Common Stock or other securities that are convertible into or exercisable for our Common Stock in connection with future acquisitions, future issuances of our securities for capital raising purposes or for other business purposes. For example, in September 2021, we issued 22,716,049 shares of Common Stock in an underwritten public offering for capital raising purposes. Future sales by us of substantial amounts of our Common Stock, or the perception that sales could occur, could have a material adverse effect on the price of our Common Stock.

We may issue preferred stock in the future, and the terms of the preferred stock may reduce the value of our Common Stock.

Under the terms of our certificate of incorporation, our Board of Directors is authorized to create and issue one or more additional series of preferred stock, and, with respect to each series, to determine number of shares constituting the series and the designations and the powers, preferences and rights, and the qualifications, limitations and restrictions thereof, which may include dividend rights, conversion or exchange rights, voting rights, redemption rights and terms and liquidation preferences, without stockholder approval. If we create and issue one or more additional series of preferred stock, it could affect your rights or reduce the value of our outstanding Common Stock. Our Board of Directors could, without stockholder approval, issue preferred stock with voting and other rights that could adversely affect the voting power of the holders of our Common Stock and which could have certain anti-takeover effects. For example, in connection with the Chubb Acquisition, in January 2022 we issued the Series B Preferred Shares which had quarterly dividend rights and which were converted into 32,803,519 shares of Common Stock (inclusive of shares attributable to accrued and unpaid dividends thereon).

Delaware law and our organizational documents contain certain provisions, including anti-takeover provisions, which limit the ability of stockholders to take certain actions and could delay or discourage takeover attempts that stockholders may consider favorable.

Our certificate of incorporation and bylaws, and the Delaware General Corporation Law (“DGCL”), contain provisions that could have the effect of rendering more difficult, delaying, or preventing an acquisition deemed undesirable by our Board of Directors and therefore depress the trading price of our Common Stock. These provisions could also make it difficult for stockholders to take certain actions, including electing directors who are not nominated by the current members of our board of directors or taking other corporate actions, including effecting changes in our management. These provisions, alone or together, could delay or prevent hostile takeovers and changes in control or changes in our Board of Directors or management.

In addition, Section 203 of the DGCL restricts certain “business combinations” with “interested stockholders” for three years following the date that a person becomes an interested stockholder unless: (1) the “business combination” or the transaction which caused the person or entity to become an interested stockholder is approved by the Board of Directors prior to such business combination or transactions; (2) upon the completion of the transaction in which the person or entity becomes an “interested stockholder,” such interested stockholder holds at least 85% of our voting stock not including (i) shares held by officers and directors and (ii) shares held by employee benefit plans under certain circumstances; or (3) at or after the person or entity becomes an “interested stockholder,” the “business combination” is approved by the board of directors and holders of at least 66 2/3% of the outstanding voting stock, excluding shares held by such interested stockholder. A Delaware corporation may elect not to be governed by Section 203. We have not made such an election.

Our stockholders may be required to bring certain actions or proceedings relating to us in the Delaware Court of Chancery and certain actions asserting claims arising under the Securities Act in the federal district courts of the United States. Chancery and certain actions asserting claims arising under the Securities Act in the federal district courts of the United States.

Pursuant to our certificate of incorporation, unless we consent in writing to an alternative forum, the Delaware Court of Chancery is the sole and exclusive forum for: (1) derivative actions or proceedings brought on behalf of us; (2) actions asserting a claim of fiduciary duty owed by any of our directors, officers or employees to us

S-11

or our stockholders; (3) civil actions to interpret, apply, enforce or determine the validity of the our certificate of incorporation or bylaws; or (4) actions asserting a claim governed by the internal affairs doctrine. Under our certificate of incorporation, if the Delaware Court of Chancery lacks jurisdiction over any of the foregoing actions or proceedings, then the sole and exclusive forum for such actions or proceedings will be another state or federal court located in the State of Delaware, as long as such court has jurisdiction over the parties. These Delaware forum provisions require our stockholders to bring certain types of actions and proceedings relating to Delaware law in the Delaware Court of Chancery or another state or federal court located in the State of Delaware and therefore may prevent our stockholders from bringing such actions or proceedings in another court that a stockholder may view as more convenient, cost-effective or advantageous to the stockholder or the claims made in such action or proceeding, or may discourage them from bringing such actions or proceedings.

In addition, pursuant to our certificate of incorporation, unless we consent in writing to an alternative forum, the U.S. federal district courts will, to the fullest extent permitted by applicable law, be the sole and exclusive forum for any action asserting a claim arising under the Securities Act of 1933, as amended (the “Securities Act”). This forum provision prevents our stockholders from bringing claims arising under the Securities Act in state court, which court our stockholders may view as more convenient, cost effective or advantageous to the claims made in such action and therefore may discourage such actions. In addition, while the Delaware Supreme Court has recently upheld provisions of the certificates of incorporation of other Delaware corporations that are similar to this forum provision, a court of a state other than the State of Delaware could decide that such provisions are not enforceable under the laws of that state.

Neither the Delaware nor the Securities Act forum provisions are intended by us to limit the forums available to our stockholders for actions or proceedings asserting claims arising under the Exchange Act.

Our stock price may be volatile and, as a result, you could lose a significant portion or all of your investment.

The market price of our Common Stock on the NYSE may fluctuate as a result of several factors, including the following:

S-12

Furthermore, the stock markets often experience significant price and volume fluctuations that have affected and continue to affect the market prices of equity securities of many companies. These fluctuations often have been unrelated or disproportionate to the operating performance of those companies. These broad market and industry fluctuations, as well as general economic, political and market conditions such as recessions or interest rate changes may cause the market price of our Common Stock to decline.

If securities or industry analysts either do not publish research about us, or publish inaccurate or unfavorable research about us, our businesses could be adversely impacted or, if such analysts change their recommendations regarding our common stock adversely, our stock price or trading volume could decline.

The trading market for our Common Stock is influenced in part by the research and reports that securities or industry analysts may publish about us, our businesses, our market, or our competitors. If one or more of the analysts initiate research with an unfavorable rating or downgrade our Common Stock, provide more favorable recommendations about our competitors, or publish inaccurate or unfavorable research about our businesses, the trading price of our Common Stock would likely decline. If any analyst who may cover us were to cease coverage of us or fail to regularly publish reports on us, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to decline.

You may experience dilution as a result of future equity offerings.

In order to raise additional capital, we may in the future offer additional shares of our Common Stock or other securities convertible into or exchangeable for our Common Stock at prices that may not be the same as the price in this offering. We may sell shares of our Common Stock or other securities in any other offering at a price that is less than the price paid by investors in this offering by the selling stockholders, and investors purchasing shares of our Common Stock or other securities in the future could have rights superior to existing stockholders. The price at which we sell additional shares of our Common Stock, or securities convertible or exchangeable into common stock, in future transactions may be higher or lower than the price paid by investors in this offering by the selling stockholders.

USE OF PROCEEDS

We will not receive any proceeds from the sale of our Common Stock by the selling stockholders. The selling stockholders will receive all of the net proceeds from the sale of our Common Stock in this offering. Under the Registration Rights Agreements (described in “Description of Capital Stock—Registration Rights” in the accompanying prospectus), we are required to bear a portion of the expenses of the offering of Common Stock, except that the selling stockholders will pay any applicable underwriting discounts, selling commissions and stock transfer taxes.

S-13

Material Relationships

In connection with the issuance of the Series B Preferred Shares, we filed a registration statement of which this prospectus supplement and the accompanying prospectus forms a part, to register the resale of up to 45,000,000 shares of Common Stock issuable upon conversion of the Series B Preferred Shares to satisfy our obligations under the Registration Rights Agreements between the Company and the selling stockholders. The Common Stock covered by this prospectus supplement is being registered pursuant to provisions of such Registration Rights Agreements.

For more information regarding the Registration Rights Agreements, see “Description of Capital Stock—Registration Rights” in the accompanying prospectus.

S-15

UNDERWRITING (CONFLICTS OF INTEREST)

UBS Securities LLC and Citigroup Global Markets Inc. are acting as representatives of the underwriters named below. Subject to the terms and conditions stated in the underwriting agreement dated the date of this prospectus supplement, each underwriter named below has severally agreed to purchase, and the Selling Stockholders have agreed to sell to that underwriter, the number of Shares set forth opposite the underwriter’s name.

The underwriting agreement provides that the obligations of the underwriters to purchase the Shares included in this offering are subject to approval of legal matters by counsel and to other conditions. The underwriters are obligated to purchase all the Shares (other than those covered by the underwriters’ option to purchase additional shares described below) if they purchase any of the Shares.

Shares sold by the underwriters to the public will initially be offered at the price to the public set forth on the cover of this prospectus supplement. Any Shares sold by the underwriters to securities dealers may be sold at a discount from the price to the public not to exceed $0.71925 per Share. If all the Shares are not sold at the initial offering price, the underwriters may change the offering price and the other selling terms.

If the underwriters sell more Shares than the total number set forth in the table above, we have granted to the underwriters an option, exercisable for 30 days from the date of this prospectus supplement, to purchase up to additional shares at the public offering price less the underwriting discount. To the extent the option is exercised, each underwriter must purchase a number of additional shares approximately proportionate to that 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.

The Shares are listed on the New York Stock Exchange under the symbol “APG.”

The following table shows the underwriting discounts and commissions that the Selling Stockholders are to pay to the underwriters in connection with this offering. These amounts are shown assuming both no exercise and full exercise of the underwriters’ option to purchase additional shares.

We estimate that our portion of the total expenses of this offering will be $1.2 million. We have also agreed to reimburse the underwriters for certain of their expenses in an amount up to $35,000. In addition, the underwriters have agreed to reimburse us for certain documented expenses incurred in connection with this offering.

Lock-Up Agreements

We, our officers and directors and certain stockholders, including the Selling Stockholders have agreed that, for a period of 90 days from the date of this prospectus supplement, we and they will not, without the prior written consent of UBS Securities LLC and Citigroup Global Markets Inc., dispose of or hedge any shares or any securities convertible into or exchangeable for our common stock. UBS Securities LLC and Citigroup Global Markets Inc. in their sole discretion may release any of the securities subject to these lock-up agreements at any time without notice.

S-16

The restrictions described in the immediately preceding paragraph do not apply to the following, subject to certain limitations and conditions:

In connection with the offering, the underwriters 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 underwriters’ option to purchase additional shares, and stabilizing purchases.

S-17

Purchases to cover short positions and stabilizing purchases, as well as other purchases by the underwriters for their own accounts, 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 underwriters may conduct these transactions on the New York Stock Exchange, in the over-the-counter market or otherwise. If the underwriters commence any of these transactions, they may discontinue them at any time.

Conflicts of Interest

Because certain affiliates of Blackstone Securities Partners L.P. are selling stockholders and will receive 5% or more of the net proceeds of this offering, Blackstone Securities Partners L.P. is deemed to have a conflict of interest within the meaning of FINRA Rule 5121. Accordingly, this offering will be conducted in accordance with FINRA Rule 5121. The appointment of a “qualified independent underwriter” is not required in connection with this offering as a “bona fide public market,” as defined in FINRA Rule 5121, exists for our common stock. Blackstone Securities Partners L.P. will not confirm any sales to any account over which they exercise discretionary authority without the specific written approval of the account holder. See “Selling Stockholders” and “Use of Proceeds” for additional information.

The underwriters are full service financial institutions 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 underwriters and their respective 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 underwriters and their respective 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.

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

European Economic Area

In relation to each Member State of the European Economic Area (each, a “Relevant State”), no ordinary shares have been offered or will be offered pursuant to this offering to the public in that Relevant State prior to the publication of a prospectus in relation to the ordinary shares which has been approved by the competent authority in that Relevant State or, where appropriate, approved in another Relevant State and notified to the competent authority in that Relevant State, all in accordance with the Prospectus Regulation, except that offers of ordinary shares may be made to the public in that Relevant State at any time under the following exemptions under the Prospectus Regulation:

provided that no such offer of ordinary shares shall require us or any underwriter to publish a prospectus pursuant to Article 3 of the Prospectus Regulation or supplement a prospectus pursuant to Article 23 of the Prospectus Regulation and each person who initially acquires any ordinary shares or to whom any offer is made will be deemed to have represented, acknowledged and agreed to and with each of the underwriters and us that it is a “qualified investor” within the meaning of Article 2(e) of the Prospectus Regulation. In the case of any ordinary shares being offered to a financial intermediary as that term is used in the Prospectus Regulation, each such financial intermediary will be deemed to have represented, acknowledged and agreed that the ordinary shares acquired by it in the offer have not been acquired on a non-discretionary basis on behalf of, nor have they been acquired with a view to their offer or resale to, persons in circumstances which may give rise to an offer of any ordinary shares to the public other than their offer or resale in a Relevant State to qualified investors as so defined or in circumstances in which the prior consent of the underwriters has been obtained to each such proposed offer or resale.

S-18

For the purposes of this provision, the expression an “offer to the public” in relation to the ordinary shares in any Relevant State means the communication in any form and by any means of sufficient information on the terms of the offer and any ordinary shares to be offered so as to enable an investor to decide to purchase or subscribe for any ordinary shares, and the expression “Prospectus Regulation” means Regulation (EU) 2017/1129, as amended.

FORWARD-LOOKING STATEMENTS

Certain statements we make in this prospectus and the documents incorporated or deemed to be incorporated by reference herein may constitute “forward-looking statements” within the meaning of the federal securities laws and are intended to qualify for the safe harbor from liability established by the Private Securities Litigation Reform Act of 1995, including statements regarding (i) the Company’s beliefs and expectations regarding its business strategies and competitive strengths, and its ability to maintain and advance its market share and position, grow its business organically and through acquisitions, and capitalize on customer demand; (ii) the Company’s beliefs regarding competition, its relative market positioning and the competitive factors in the industries it serves; (iii) the Company’s beliefs regarding its acquisition platform and ability to execute on and successfully integrate strategic acquisitions; (iv) the Company’s beliefs regarding the recurring and repeat nature of its business; (v) the Company’s expectations regarding industry trends and their impact on its business, and its ability to capitalize on the opportunities presented in the markets it serves; (vi) the Company’s intent to continue to grow its business, both organically and through acquisitions, and the Company’s beliefs regarding the impact of its business strategies on its growth; (vii) the Company’s expectations regarding the impact of the COVID-19 pandemic on its business, including the seasonal and cyclical volatility of its business and future financial results, and the precautionary measures the Company is taking in response to the pandemic and the impact of those measures on the Company’s business and future financial results; (viii) the Company’s expectations regarding future capital expenditures; (ix) the Company’s beliefs regarding its ability to pass along commodity price increases to its customers; (x) the Company’s beliefs regarding market risk and its ability to mitigate that risk; (xi) the Company’s plans and beliefs with respect to its leadership development platform; (xii) the Company’s beliefs regarding its customer relationships and plans to grow existing business and expand service offerings; (xiii) the Company’s beliefs regarding the sufficiency of its properties and facilities; (xiv) the Company’s expectations regarding labor matters; (xv) the Company’s beliefs regarding the adequacy of its insurance coverage and at reasonable cost; (xvi) the Company’s expectations regarding the increased costs and burdens of being a public company; (xvii) the Company’s expectations regarding the cost of compliance with laws and regulations; (xviii) the Company’s expectations and beliefs regarding accounting and tax matters; (xix) the Company’s beliefs regarding the sufficiency of its current sources of liquidity to fund its future liquidity requirements, the Company’s expectations regarding the types of future liquidity requirements and its expectations regarding the availability of future sources of liquidity; (xx) the Company’s expectations regarding the acquisition of Chubb’s fire and security business, including the expected benefits of the acquisition and future value creation opportunities; (xxi) the Company’s intent to settle future dividends on Series A Preferred Stock in shares; (xxii) the Company’s assumption as to accrued and unpaid dividends on the Series B Preferred Stock and the number of Conversion Shares; and (xxiii) the Company’s estimate as to the number of Dividend Shares it may issue as a payment-in-kind on the Series B Preferred Stock.

THE OFFERING

THE COMPANY

Overview

We are a market-leading business services provider of safety, specialty and industrial services in over 200 locations in North America and Europe. We provide statutorily mandated and other contracted services to a strong base of long-standing customers across industries. We have a winning leadership culture driven by entrepreneurial business leaders who deliver innovative solutions for our customers.

We believe that our core strategies of driving organic growth and growth through accretive acquisitions, promoting sharing of best practices across all of our businesses and leveraging our scale and services offerings, place us in the position to capitalize on opportunities and trends in the industries we serve, grow our businesses and advance our position in each of our markets. We believe that our diverse customer base, regional approach to operating our businesses, specialty operations in niche markets, strong commitment to leadership development, long-standing customers with a robust reputation in the industries we serve, and strong safety track record differentiate us from our competitors.

We operate our business under three operating segments, which are also our reportable segments:

Recent Developments

Chubb Acquisition

On January 3, 2022, we acquired the Chubb fire and security business (the “Chubb Business”), through the acquisition of Chubb Limited (“Chubb”) for an enterprise value of $3.1 billion, which is comprised of $2.9 billion cash and approximately $200 million of assumed liabilities, and other adjustments (the “Chubb Acquisition”), pursuant to a Stock Purchase Agreement (the “Purchase Agreement”), dated July 26, 2021, with Carrier Global Corporation (“Carrier”), Carrier Investments UK Limited (“Seller”) and Chubb.

The cash consideration for the Chubb Acquisition was funded through a combination of cash on hand, the private placement of the Series B Preferred Stock pursuant to the Securities Purchase Agreements and the 2021 Term Loan financing (each described below).

Overview of Chubb Business

Chubb is a full-service provider of fire and electronic security services, including integrated system sales, design, installation, service and monitoring. With an over 200-year history, Chubb is an internationally-recognized brand with approximately 13,000 employees and a presence in 17 countries. Chubb has leading life safety services market positions in France, the U.K., Australia, Canada, Hong Kong and the Netherlands, based on market research.

Like APi, Chubb provides end-to-end services including design and installation, service and maintenance and monitoring through its life safety and security services businesses. Chubb’s life safety services offerings include detection and alarm systems, fire protection equipment, fire suppression systems and water mist systems. Chubb’s security services offerings include integrated security solutions, monitoring, video verification and remote guarding, intruder detection and access control. The Chubb Business enjoys a well-diversified customer mix across geographies, end markets and customer type. For 2020, Chubb’s top six geographic markets accounted for approximately 90% of its revenue.

We believe that the Chubb Business is complementary to our existing life safety business, including the recurring, predictable revenue nature of the business. With a focus on service, according to Chubb’s estimates, historically over 60% of the Chubb Business revenue has been recurring in nature, which we expect will support our goal of increasing the mix of our service revenue as a proportion of net revenues to 50% or greater. We expect that the Chubb Acquisition will increase our safety services offerings.

The Chubb Business supports the customer’s life cycle, including through (1) the design and installation phase which establishes the foundation for future recurring revenue and additional pull-through revenue opportunities through future upgrades and repair, (2) ongoing service, maintenance and updating of systems through multi-year service contracts with recurring revenue opportunities and frequent customer interaction and (3) 24/7 secure remote monitoring through a network of monitoring centers. By committing to an investment in and support of the Chubb team, we expect to drive improvements in the Chubb Business and realize an enhanced financial profile consistent with our existing life safety business.

With its low capital intensive business, strong historical free cash flow conversion and recurring revenue business model, we believe that the Chubb Business offers compelling synergies and will serve as an enhanced services platform for growth and margin expansion, including complementary offerings and cross-selling opportunities among our existing businesses, consistent with our organic growth strategy. We plan to drive operational improvements and reinvest free cash flow, which we expect will lead to increased stockholder value. Following the Chubb Acquisition, we expect our near-term capital allocation plan will focus on deleveraging through an asset-light, high free cash flow conversion operating model and have a goal of returning to below 3.0 times net leverage quickly. There can be no assurance that we will achieve this goal.

We believe that Chubb’s experienced management team fosters a performance and entrepreneurial leadership culture that is aligned with APi’s values and complements our leadership development mindset. We plan to integrate and enhance the combined culture and values to bring out the best of the combined organization.

USE OF PROCEEDS

We will not receive any proceeds from the sale of any securities by the selling stockholders.

The selling stockholders will receive all of the net proceeds from the sale of any securities under this prospectus. The selling stockholders will pay any underwriting discounts, selling commissions and stock transfer taxes, if any, incurred by the selling stockholders in disposing of these shares. We will bear all other costs, fees and expenses incurred in effecting the registration of the securities covered by this prospectus.

SELLING STOCKHOLDERS

This prospectus covers the public resale of the securities owned by the selling stockholders listed in the table below. The selling stockholders may from time to time offer and sell pursuant to this prospectus any or all of the Conversion Shares (i.e., shares of common stock issued upon conversion of shares of the Series B Preferred Stock) or any Dividend Shares (i.e., shares of common stock as 5.5% per annum dividends on shares of Series B Preferred Stock that are payable and accrue quarterly) owned by them, but are not obligated to do so. See “Plan of Distribution.” The selling stockholders make no representation that the securities will be offered for sale. The table below presents information regarding the selling stockholders and the securities that they may offer and sell from time to time under this prospectus. For purposes of this prospectus, the selling stockholders include the holders set forth in the table below, as may be amended or supplemented, and their permitted transferees, pledgees, assignees, distributees, donees or successors or others who later hold any of its interests, or the selling stockholders.

In the table below, the number of shares of common stock that may be offered pursuant to this prospectus is calculated based on (i) an assumed conversion of all shares of Series B Preferred Stock outstanding as of January 3, 2022 at a conversion price of $24.60 per share and (ii) an assumed amount of Dividend Shares that may be issued on shares of Series B Preferred Stock as quarterly dividends while the Series B Preferred Stock is outstanding. The number of shares of common stock into which the Series B Preferred Stock is convertible is subject to adjustment under certain circumstances. Accordingly, the number of Conversion Shares issuable upon conversion of the Series B Preferred Stock, and the number of Dividend Shares that may be issued on shares of Series B Preferred Stock, in each case beneficially owned and offered by the selling stockholders pursuant to this prospectus, may increase or decrease from that set forth in the below table and elsewhere in this prospectus.

All information with respect to common stock ownership of the selling stockholders, other than the estimate of the amount of Dividend Shares, has been furnished by or on behalf of the selling stockholders and is as of January 3, 2022. We believe, based on information supplied by the selling stockholders, that except as may otherwise be indicated in the table below, the selling stockholders and their affiliates listed in any footnote to the table below have sole voting and dispositive power with respect to the securities reported as beneficially owned by them. Because the selling stockholders may sell some or all of the securities included in this prospectus, and

8

because there are currently no agreements, arrangements or understandings with respect to the sale of any of the securities, no estimate can be given as to the number of securities available for resale by this prospectus that will be held by the selling stockholders in the future. In addition, the selling stockholders may have sold, transferred or otherwise disposed of, or may sell, transfer or otherwise dispose of, at any time and from time to time, the securities they hold in transactions exempt from the registration requirements of the Securities Act after the date on which they provided the information set forth on the table below. We have, therefore, assumed for the purposes of the following table, that the selling stockholders will sell all of the securities owned beneficially by them and their affiliates listed in any footnote to the table below that are covered by this prospectus.

These securities may be offered from time to time by the selling stockholders named in this prospectus. The selling stockholders, which, as used herein, includes donees, pledgees, transferees or other successors-in-interest selling Conversion Shares or Dividend Shares received after the date of this prospectus from the selling stockholders as a gift, pledge, partnership distribution or other transfer, may, from time to time, sell, transfer or otherwise dispose of any or all of the securities on any stock exchange, market or trading facility on which our common stock is traded or in private transactions. These dispositions may be at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale, or at negotiated prices.

The selling stockholders may use any one or more of the following methods when disposing of securities:

The selling stockholders may, from time to time, pledge or grant a security interest in some or all of the securities they own and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the securities, from time to time, under this prospectus, or under an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act amending the list of selling stockholders to include any donee, pledgee, transferee or other successors-in-interest as selling stockholders under this prospectus. The selling stockholders also may transfer the securities in other circumstances, in which case the donees, transferees, pledgees or other successors-in-interest will be the selling beneficial owners for purposes of this prospectus.

In connection with the sale of the securities or interests therein, the selling stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of such securities in the course of hedging the positions they assume. The selling stockholders may also sell securities short and deliver these securities to close out their short positions, or loan or pledge the common stock to broker-dealers that in turn may sell these securities. The selling stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or create one or more derivative securities which require the delivery to such broker-dealer or other financial institution of the securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

12

The aggregate proceeds to the selling stockholders from the sale of the securities offered hereby will be the purchase price of such securities less discounts or commissions, if any. The selling stockholders reserve the right to accept and, together with their agents from time to time, to reject, in whole or in part, any proposed purchase of common stock to be made directly or through agents. We will not receive any of the proceeds from the resale of the securities.

The selling stockholders also may resell all or a portion of the securities in open market transactions in reliance upon Rule 144 under the Securities Act, provided that it meets the criteria and conforms to the requirements of that rule.

The selling stockholders and any underwriters, broker-dealers or agents that participate in the sale of the common stock therein may be “underwriters” within the meaning of Section 2(11) of the Securities Act. Any discounts, commissions, concessions or profit they earn on any resale of the securities may be underwriting discounts and commissions under the Securities Act. Selling stockholders who are “underwriters” within the meaning of Section 2(11) of the Securities Act will be subject to the prospectus delivery requirements of the Securities Act.

To the extent required, the securities to be sold, the names of the selling stockholders, the respective purchase prices and public offering prices, the names of any agents, dealers or underwriters and any applicable commissions or discounts with respect to a particular offer will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement that includes this prospectus.

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

We have advised the selling stockholders that the anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of securities in the market and to the activities of the selling stockholders and their affiliates. In addition, to the extent applicable we will make copies of this prospectus (as it may be supplemented or amended from time to time) available to the selling stockholders for the purpose of satisfying the prospectus delivery requirements of the Securities Act. The selling stockholders may indemnify any broker-dealer that participates in transactions involving the sale of the securities against certain liabilities, including liabilities arising under the Securities Act.

We entered into a Registration Rights Agreement with each of the holders of the Series B Preferred Stock to register the Conversion Shares and the Dividend Shares under applicable federal securities laws under specific circumstances and specific times. We will pay all expenses of the registration of the Conversion Shares and Dividend Shares pursuant the applicable Registration Rights Agreement, including, without limitation, SEC filing fees, expenses of compliance with state securities or “blue sky” laws and certain related fees and disbursements of one counsel for the selling stockholders; provided, however, that the selling stockholders will pay all underwriting discounts, selling commissions and stock transfer taxes, if any.

See “Where Can You Find More Information.”

Common Stock

Except as otherwise required by applicable law or as provided by the certificate of incorporation, including, without limitation, the Series B Certificate of Designation, each holder of common stock is entitled to one vote for each share of common stock owned of record on all matters on which stockholders of the Company are generally entitled to vote. Except as otherwise required by applicable law or as provided by the certificate of incorporation, including matters required to be submitted solely to a vote of the holders of the Series A Preferred Stock or Series B Preferred Stock (or any other series of preferred stock of the Company then outstanding), holders of common stock (as well as holders of any series preferred stock then outstanding and entitled to vote together with the holders of common stock, including the Series A Preferred Stock and Series B Preferred Stock) vote together as a single class on all matters presented to the Company’s stockholders for their vote or approval, including the election of directors. There are no cumulative voting rights with respect to the election of directors or any other matters submitted to a vote of the holders of common stock.

Dividends and distributions

Subject to applicable law and the rights of the holders of Series A Preferred Stock and Series B Preferred Stock and the rights, if any, of the holders of any other series of preferred stock of the Company then outstanding, the holders of common stock have the right to receive dividends and distributions, whether payable in cash or otherwise, as may be declared from time to time by the Company’s board of directors from amounts legally available therefor.

Liquidation, dissolution or winding up

Subject to applicable law and the rights, if any, of the holders of any series of preferred stock of the Company then outstanding, including the Series A Preferred Stock and Series B Preferred Stock, in the event of the liquidation, dissolution or winding-up of the Company, holders of our common stock will be entitled to share ratably in proportion to the number of shares of common stock held by them in the assets of the Company available for distribution after payment or reasonable provision for the payment of all creditors of the Company.

Redemption, conversion or preemptive rights

Holders of common stock have no redemption rights, conversion rights or preemptive rights to subscribe to any or all additional issues of shares of capital stock of the Company or securities convertible into capital stock of the Company.

14

Other provisions

There are no redemption provisions or sinking fund provisions applicable to the common stock.

The designations and the powers, preferences and rights, if any, and the qualifications, limitations and restrictions, if any, of the holders of our common stock will be subject to, and may be adversely affected by, the designations and the powers, preferences and rights, if any, and the qualifications, limitations and restrictions, if any, of the holders of any series of preferred stock of the Company then outstanding, including the Series A Preferred Stock and Series B Preferred Stock.

Listing

Currently, our common stock is listed on the NYSE under the ticker symbol “APG.”

Preferred Stock

Blank Check Preferred

Under our certificate of incorporation, without stockholder approval, the Company’s board of directors is authorized to create one or more series of preferred stock of the Company (in addition to the Series A Preferred Stock) by resolution, and, with respect to each such series, to determine the number of shares constituting the series and the designations and the powers (including voting powers), preferences and rights, if any, which may include dividend rights, conversion or exchange rights, redemption rights and liquidation preferences, and the qualifications, limitations and restrictions, if any, of the series. The Company’s board of directors may therefore create and issue one or more new series of preferred stock with voting power and preferences and rights that could adversely affect the holders of the Company’s common stock and which could have certain anti-takeover effects. Before the Company may issue any new series of preferred stock, our board of directors will be required to adopt resolutions creating and designating such series of preferred stock and certificate of designations setting forth a copy of such resolutions will be required to be executed, acknowledged and filed with the Secretary of State of the State of Delaware.

Series A Preferred Stock

As of December 31, 2021, the Company had 4,000,000 shares of Series A Preferred Stock issued and outstanding. The designations and the powers, preferences and rights, and the qualifications, limitations and restrictions of the Series A Preferred Stock are set forth in our certificate of incorporation.

Dividends

Subject to applicable law and the rights, if any, of any series of preferred stock of the Company then outstanding ranking senior to the Series A Preferred Stock as to dividends (which includes the Series B Preferred Stock) and on parity with the rights, if any, of any series of the Company’s preferred stock then outstanding ranking on parity with the Series A Preferred Stock from and after the Average Price (as defined in our certificate of incorporation) per share of the Company’s common stock (subject to adjustment in accordance with our certificate of incorporation) is $11.50 or more for any ten consecutive trading days, the holders of the Series A Preferred Stock will be entitled to receive, in respect of each Dividend Year (as defined below), in the aggregate, the “Annual Dividend Amount,” which is calculated as follows (the “Annual Dividend Amount”):

A X B, where:

A = an amount equal to 20% of the increase (if any) in the value of a share of the Company’s common stock, such increase calculated as being the difference between (i) the Average Price (as defined in the certificate of incorporation) per share of common stock over the last ten consecutive trading days of the Dividend Year for such Dividend Year (the “Dividend Price”) and (ii) (x) if no Annual Dividend Amount has previously been paid, a price of $10.00 per share of common stock, or (y) if an Annual Dividend Amount has previously been paid, the highest Dividend Price for any prior Dividend Year (subject to adjustment in accordance with the certificate of incorporation); and

15

B = 141,194,638 shares, being a number of shares of the Company’s common stock equal to the number of ordinary shares of the Company’s predecessor outstanding immediately following the acquisition of APi Group, Inc. by the Company (the “APi Acquisition”), including any ordinary shares issued pursuant to the exercise of warrants of the Company, but excluding any ordinary shares issued to shareholders or other beneficial owners of APi Group, Inc. in connection with the APi Acquisition, which such number of shares is subject to adjustment as provided in the certificate of incorporation (the “Series A Preferred Dividend Equivalent”).

“Dividend Year” means the Company’s financial year (which may be twelve months or any longer or shorter period) as determined by the Company’s board of directors, except that (i) in the event of the Company’s dissolution, the relevant Dividend Year will end on the trading day immediately prior to the date of dissolution and (ii) in the event of the automatic conversion of shares of Series A Preferred Stock into shares of common stock of the Company, the relevant Dividend Year will end on the trading day immediately prior to the date of such automatic conversion.

The Annual Dividend Amount is payable in shares of the Company’s common stock or cash, as determined by the Company’s board of directors. Each Annual Dividend Amount will be divided between the holders of Series A Preferred Stock pro rata based on the number of Series A Preferred Stock held by them on the last day of the relevant Dividend Year (the “Dividend Date”). If the Company’s board of directors determines to pay the Annual Dividend Amount in shares of common stock, then each holder of a share of Series A Preferred Stock will be entitled to receive such number of whole shares of common stock as is determined by dividing the pro rata amount of the Annual Dividend Amount to which such holders is entitled by the relevant Dividend Price (provided that any fractional shares of common stock due pursuant to such calculation shall not be paid and instead the nearest lower whole number of shares of common stock will be paid).

Subject to applicable law and the rights, if any, of any series of preferred stock of the Company then outstanding ranking senior to the Series A Preferred Stock as to dividends (which includes the Series B Preferred Stock) and on parity with the common stock of the Company and any series of preferred stock of the Company ranking on parity with such common stock, (i) a dividend per share of Series A Preferred Stock equal to the product obtained by multiplying the number of shares of common stock into which such shares of Series A Preferred Stock could then be converted, by the dividend payable on each such share of common stock, and (ii) a dividend per share of Series A Preferred Stock equal to the amount determined by dividing an amount equal to 20% of the dividend which would be distributable on such number of shares of common stock equal to the Series A Preferred Dividend Equivalent, by the number of shares of Series A Preferred Stock outstanding.

Automatic Conversion

The Series A Preferred Stock will be automatically converted into shares of the Company’s common stock on a one-for-one basis (subject to adjustment in accordance with the certificate of incorporation) on the last day of the seventh full financial year of the Company following October 1, 2019 (or if such date is not a trading day, the first trading day immediately following such date) (the “Automatic Conversion”).

Optional Conversion

By notice in writing and surrender of the relevant certificate or certificates to the Company, a holder of Series A Preferred Stock will be able to convert some or all of such holder’s Series A Preferred Stock into an equal number of shares of the Company’s common stock (subject to adjustment in accordance with the certificate of incorporation) and, in such circumstances, the shares of Series A Preferred Stock that were subject to such notice will be converted into shares of common stock on the fifth trading day after receipt by the Company of such written notice and certificate or certificates (the “Optional Conversion”). In the event of an Optional Conversion, no relevant portion of the Annual Dividend Amount will be payable in respect of those shares of Series A Preferred Stock that are converted into shares of common stock for the Dividend Year in which the date of the Optional Conversion occurs.

16

Voting Rights

Each holder of Series A Preferred Stock is entitled to one vote per share of Series A Preferred Stock on all matters on which stockholders of the Company generally are entitled to vote. The holders of Series A Preferred Stock also have the right to vote separately as a single class on any amendment to the certificate of incorporation, whether by merger, consolidation or otherwise, that would alter or change the powers, preferences or rights or the qualifications, limitations or restrictions of the Series A Preferred Stock so as to affect them adversely and as provided by applicable Delaware law.

Series B Preferred Stock

As of January 3, 2022, the Company had 800,000 shares of Series B Preferred Stock issued and outstanding. The designations and the powers, preferences and rights, and the qualifications, limitations and restrictions of the Series B Preferred Stock are set forth in our certificate of incorporation, which includes the certificate of designation governing the Series B Preferred Stock (the “Series B Certificate of Designation”).

Dividends

Subject to applicable law and the rights, if any, of any series of preferred stock of the Company then outstanding ranking senior to the Series B Preferred Stock as to dividends and on parity with the rights, if any, of any series of the Company’s preferred stock then outstanding ranking on parity with the Series B Preferred Stock as to dividends, the holders of Series B Preferred Stock (each, a “Holder” and collectively, the “Holders”) will be entitled to cumulative dividends at a rate of 5.5% per annum on the Liquidation Preference (as defined below), payable quarterly in cash or, if permitted, shares of common stock (“Regular Dividends”). Subject to applicable law and the rights, if any, of any series of preferred stock of the Company then outstanding ranking senior to the Series B Preferred Stock as to dividends and on parity with the rights, if any, of any series of the Company’s preferred stock then outstanding ranking on parity with the Series B Preferred Stock as to dividends, the Holders are also entitled to participate in dividends declared or paid on the common stock on an as-converted to common stock basis (the “Participating Dividends”). The Series B Preferred Stock ranks senior to the common stock and Series A Preferred Stock with respect to dividends and upon the voluntary or involuntary liquidation, dissolution, or winding up of the Company (a “Liquidation”). Upon a Liquidation, each share of Series B Preferred Stock will be entitled to receive the greater of an amount per share equal to (a) the sum of $1,000, plus all accrued and unpaid dividends (the “Liquidation Preference”), and (b) the amount that would have been received in respect of such share had it been converted into common stock.

Regular Dividends are declared and paid in either cash or, if permitted, shares of common stock, will be paid to the Holders pro rata based on the number of shares of Series B Preferred Stock held by them on the relevant Regular Dividend Record Date (as defined below). Regular Dividends may be paid in shares of common stock rather than cash, as determined by the Company’s board of directors, only if the Company determines that certain common stock liquidity conditions (including that the shares of common stock issuable are registered pursuant to an effective registration statement under the Securities Act) are satisfied on the relevant Regular Dividend Payment Date (as defined below). If Regular Dividends are paid in shares of common stock, then each Holder will be entitled to receive such number of whole shares of common stock as is determined by dividing the pro rata amount of Regular Dividends to which such Holder is entitled by the average price per share of common stock (determined as provided in the Series B Certificate of Designation) for the period starting on the date that is ten trading days prior to the applicable Regular Dividend Record Date and ending on the business day preceding the applicable Regular Dividend Payment Date (provided that any fractional shares of common stock due pursuant to such calculation shall not be paid and instead the nearest lower whole number of shares of common stock will be paid).

Regular Dividends will be computed on the basis of a 360-day year comprised of twelve 30-day months. Regular Dividends on each share of Series B Preferred Stock will accrue on the Liquidation Preference of such share as of immediately before the preceding Regular Dividend Payment Date (or, if there is no preceding Regular Dividend Payment Date, on the closing date under the Securities Purchase Agreements).

17

“Regular Dividend Payment Date” means each March 31, June 30, September 30 and December 31 of each year, beginning on the first of the foregoing dates occurring after the closing date under the Securities Purchase Agreements.

“Regular Dividend Record Date” means the close of business on either: (a) March 15^th, in the case of a Regular Dividend Payment Date occurring on March 31^st; (b) June 15^th, in the case of a Regular Dividend Payment Date occurring on June 30^th; (c) September 15^th, in the case of a Regular Dividend Payment Date occurring on September 30th; and (d) December 15^th, in the case of a Regular Dividend Payment Date occurring on December 31^st, or, if such day is not a business day, the first business day following such day.

Mandatory Conversion

The Company may, at its option, effect conversion of all, but not less than all, of the outstanding shares of Series B Preferred Stock to common stock, but only if the volume-weighted average price of the common stock (determined as provided in the Series B Certificate of Designation) for 15 consecutive trading days exceeds 150% of the conversion price equal to $24.60 per share (subject to certain customary adjustments in the event of certain events affecting the price of the common stock) (the “Conversion Price”); provided, however, that the Company may not effect such conversion unless certain common stock liquidity conditions (including that the shares of common stock issuable are registered pursuant to an effective registration statement under the Securities Act) are satisfied with respect to such conversion; provided, further, that such conversion will not apply to any share of Series B Preferred Stock for which a “Fundamental Change” repurchase notice has been delivered and not withdrawn by the holder thereof; provided, further, that the Company may not effect such conversion if it does not have sufficient authorized and unissued and unreserved shares of common stock to effect such conversion.

Optional Conversion

By notice in writing and surrender of the relevant certificate or certificates to the Company, a Holder of Series B Preferred Stock may elect to convert all, or any whole number of shares that is less than all, of such Holder’s Series B Preferred Stock to common stock at the then-applicable Conversion Price, except that such conversion is not permitted if a “Fundamental Change” repurchase notice has been delivered with respect to such share or shares (subject to certain exceptions), such share or shares have been called for redemption (subject to certain exceptions), such share or shares are subject to a mandatory conversion and such notice and surrender is submitted after the close of business on the business day immediately prior to the mandatory conversion date or the Company does not have sufficient authorized and unissued and unreserved shares of common stock to effect such conversion (the “Optional Conversion”). No adjustment will be made to the Conversion Price to account for any accumulated and unpaid Regular Dividends on any shares of Series B Preferred Stock being converted pursuant to an Optional Conversion. In the event that the Optional Conversion occurs after the date fixed to determine the Holders of Series B Preferred Stock entitled to a Regular Dividend or Participating Dividend (the “Record Date”) but before the next payment date, then such dividend will be paid notwithstanding such conversion.

Redemption Rights

The Company may redeem any or all of the Series B Preferred Stock on a date fixed by the Company for redemption that is on or after the five year anniversary of the closing date under the Securities Purchase Agreements for cash in an amount equal to the product of the Liquidation Preference on the close of business on such redemption date and 105%; provided that the Company may not redeem such shares of Series B Preferred Stock unless it has sufficient funds legally available and is permitted under the terms of its indebtedness for borrowed money to effect such redemption and certain common stock liquidity conditions are satisfied on such redemption date.

18

Right of Holders to Cause Company Repurchase

If a “Fundamental Change” (as defined in the Series B Certificate of Designation to include certain change of control transactions, as sale of all or substantially all of the assets of the Company and its subsidiaries (taken as a whole) or certain de-listing events), a Holder may elect to either (a) convert all or a portion of such Holder’s shares of Series B Preferred Stock into shares of common stock at the then-applicable Conversion Price, effective as of immediately prior to such Fundamental Change, or (b) require the Company to repurchase all or any whole number of such Holder’s shares of Series B Preferred Stock (that have not been converted into shares of common stock) for cash (out of funds legally available therefor) equal to the greater of (i) the sum of the Liquidation Preference, plus the “Make-Whole Amount” determined pursuant to the Series B Certificate of Designation and (ii) the amount such Holder would have received had such Holder exercised such Holder’s option to convert such shares of Series B Preferred Stock into common stock immediately prior to such “Fundamental Change.”

Voting Rights

Subject to applicable law, each holder of a share of Series B Preferred Stock is entitled to vote the number of votes equal to the number of shares of common stock into which such share could be converted on all matters on which stockholders of the Company generally are entitled to vote.

Additionally, the consent of the Holders of a majority of the outstanding voting power of the Series B Preferred Stock, voting separately as a single class, will be required for so long as any shares of the Series B Preferred Stock remain outstanding for (i) amendments to the certificate of designation or the Company’s certificate of incorporation that would alter or change the powers, if any, or the preferences or relative, participating, optional, special or other rights, if any, or the qualifications, limitations or restrictions, if any, thereof, (ii) any increase or decrease of the authorized number of shares of Series B Preferred Stock, (iii) any issuance of shares of Series B Preferred Stock, (iv) the creation of any new class or series of stock of the Company that is senior to, or on parity with, the Series B Preferred Stock, (v) any amendments to the Company’s certificate of incorporation, bylaws or the Series B Certificate of Designation in a manner that adversely affects the Series B Preferred Stock, (vi) any action to deregister or delist the common stock from a national securities exchange, or (vii) the entrance into a transaction with an affiliate of the Company other than on terms no less favorable to the Company than would be obtained in an arms’ length transaction with a bona fide third party, as determined by the board of directors of the Company in its reasonable judgment. In addition, any action that would adversely affect the rights of any Holder in a manner disproportionate to the other Holders will require the consent of such affected Holder.

Preemptive Rights

Under each Securities Purchase Agreement, so long as the applicable Holder holds at least 50% of the Series B Preferred Stock issued to them, at any time the Company makes any non-public offering of any capital stock or securities convertible into capital stock (subject to certain customary exceptions), such Holder shall have the right to acquire from the Company its pro rata portion of the capital stock being offered for the same price and on the same terms being offered. These customary exceptions include (1) issuances to directors, officers and employees, including pursuant to the Company’s equity plans, (2) issuances made as consideration for acquisitions, (3) issuances of securities as a result of a stock split, stock dividend, spin-off, reclassification or reorganization or similar event and (4) securities issued pursuant to the conversion, exercise or exchange of Series B Preferred Stock.

Exclusive Forum

The Company’s certificate of incorporation provides that unless we consent in writing to the selection of an alternative forum, the Delaware Court of Chancery will be the sole and exclusive forum for: (1) derivative actions or proceedings brought on behalf of us; (2) actions asserting a claim of fiduciary duty owed by any of our directors, officers or employees to us or our stockholder; (3) civil actions to interpret, apply, enforce or determine the validity of the certificate of incorporation or bylaws; or (4) actions asserting a claim governed by the internal affairs doctrine. If the Delaware Court of Chancery lacks jurisdiction over any of the foregoing actions or proceedings, the certificate of incorporation provides that the sole and exclusive forum for such actions or proceedings will be another state or federal court located in the State of Delaware, as long as such court has personal jurisdiction over the parties. In addition, the certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the federal district courts of the United States will, to the fullest extent permitted by applicable law, be the sole and exclusive forum for any action asserting a claim arising under the Securities Act.

Registration Rights

Existing Viking Global Investors Registration Rights Agreement

On March 24, 2020, we entered into a registration rights agreement with Viking Global Opportunities Liquid Portfolio Sub-Master LP (“Viking Liquid LP”) to register for resale the 25,000,000 shares of our common stock acquired by Viking Liquid LP in our initial public offering and the 8,333,333 shares of our common stock held by Viking Liquid LP’s as a result of its exercise of 25,000,000 warrants on October 1, 2019 (which shares were subsequently transferred, and registration rights assigned, to Viking Liquid LP’s affiliate, Viking Global Opportunities Illiquid Investments Sub-Master LP (“Viking Opportunities Fund”). Pursuant to the registration rights agreement, we filed with the SEC a registration statement registering the resale of such common stock. In addition, pursuant to the registration rights agreement, if we propose to register any shares of common stock under the Securities Act in connection with the public offering of such securities solely for cash (other than in certain excluded registrations), we will register all of the shares that the Viking Opportunities Fund requests to be included in such registration (subject to customary cutbacks if the underwriters determine that less than all of the shares requested to be registered can be included in such offering).

Registration Rights Agreements with the Purchasers

In connection with the issuance of the Series B Preferred Stock, on January 3, 2022, we entered into Registration Rights Agreements with the Purchasers. We are filing the registration statement to satisfy our obligations under the Registration Rights Agreement to register the resale of the Conversion Shares and Dividend Shares.

In addition, pursuant to the Registration Rights Agreement, if we propose to register any shares of common stock under the Securities Act in connection with the public offering of such securities solely for cash, we will register all of the shares that the Purchasers request to be included in such registration (subject to customary cutbacks if the underwriters determine that less than all of the shares requested to be registered can be included in such offering). We will use commercially reasonable efforts to cause the registration statement of which this prospectus is a part or a subsequent registration statement to be continuously effective and usable for so long as any registrable securities remain outstanding.

The holders also have the right under each Registration Rights Agreement to request one or more underwritten offerings, so long as the anticipated gross proceeds of such underwritten offering is not less than $25 million (unless such holders are proposing to sell all of their remaining registrable securities, in which case no such minimum gross proceeds threshold shall apply), and the holders have the right to request unlimited non-underwritten shelf take-downs. We will not be obligated to effect more than two underwritten offerings for a particular Purchaser during any 12 month period.

In addition, we agreed, among other things, to use commercially reasonable efforts to (i) file with the SEC in a timely manner all reports and other documents required under the Exchange Act and (ii) furnish certain information as may be requested by the Purchasers as to our compliance with the reporting requirements of the Exchange Act. The Registration Rights Agreements also contain customary indemnities.

Our obligations under the Registration Rights Agreements will terminate as to a particular Purchaser when all shares that are registrable under the Registration Rights Agreements are no longer held by such Purchaser.

Indemnification of Directors and Officers

Under the General Corporation Law of the State of Delaware (the “DGCL”), a Delaware corporation may include in its certificate of incorporation a provision that, subject to the limitations described below, eliminates or limits the personal liability of a director to the corporation or its stockholders for monetary damages for breaches of fiduciary duty as a director. Such a provision may not eliminate or limit the liability of a director for (i) any breach of the duty of loyalty to the corporation or its stockholders, (ii) acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, (iii) the willful or negligent payment of unlawful dividends or

20

purchases or redemptions of shares of stock, or (iv) transactions from which such director derived an improper personal benefit. The Company’s certificate of incorporation includes a provision providing that directors of the Company shall not be liable to the Company or our stockholders for monetary damages for breach of fiduciary duty, except to the extent such exemption or limitation is not permitted by the DGCL.

The DGCL also provides that a Delaware corporation has the power to indemnify any person who is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding (whether civil, criminal, administrative or investigative) by reason of the fact that such person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee of another entity, against reasonable expenses (including attorneys’ fees) and, in actions not brought by or in the right of the corporation, judgments, fines and amounts paid in settlement, in each case, actually and reasonably incurred in connection with such action, suit or proceeding, but only if such person acted in a manner reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action, had no reasonable cause to believe his or her conduct was unlawful, except that in any action brought by or in the right of the corporation, such indemnification may not be made if such person is adjudged liable to the corporation (unless otherwise determined by the court in which such action, suit or proceeding was brought or the Delaware Court of Chancery). In addition, under Delaware law, to the extent that a present or former director or officer of a Delaware corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to above or any claim, issue or matter therein, he or she must be indemnified by the corporation against expenses (including attorneys’ fees) actually and reasonably incurred by him or her. Furthermore, under Delaware law, a Delaware corporation is permitted to maintain directors’ and officers’ insurance.

The Company’s bylaws require the Company to indemnify any person who is or was a party or is threatened to be made a party to or is otherwise involved in any action, suit or proceeding described above by reason of the fact that such person is or was a director of the Company or, while a director or officer of the Company, is or was serving at the request of the Company as a director, officer, employee or agent of another entity, to the fullest extent permitted by law. The Company’s bylaws also require the Company to pay the legal expenses (including attorneys’ fees) of any such person in defending any such action, suit or proceeding in advance of its final disposition subject, in the case of present directors and officers, to the provision by such director or officer of an undertaking to repay the amounts advanced if it is ultimately determined that such director or officer is not entitled to be indemnified under the bylaws or otherwise.

Anti-Takeover Effects of Delaware Law and the Certificate of Incorporation and Bylaws

Delaware law and the Company’s certificate of incorporation and bylaws contain provisions that may prevent or discourage a third party from acquiring the Company, even if the acquisition would be beneficial to our stockholders.

Pursuant to the certificate of incorporation, our board of directors have the authority to create one or more series of preferred stock of the Company (in addition to the Series A Preferred Stock and Series B Preferred Stock) and to fix the designations and the powers, preferences and rights, if any, and the qualifications, limitations and restrictions, if any, of shares of such new series of preferred stock of the Company and to issue shares of such series without a stockholder vote, which could be used to dilute the ownership of a hostile acquiror.

Pursuant to the certificate of incorporation, our board of directors have the power to amend the bylaws of the Company, which may allow our board of directors to take certain actions to prevent an unsolicited takeover.

The Company is also subject to Delaware law prohibiting the Company from engaging in any “business combination” with an “interested stockholder” for a period of three years subsequent to the time that the stockholder became an interested stockholder unless:

21

For purposes of Delaware law, an “interested stockholder” generally is defined as an entity or person (other than the corporation and any direct or indirect majority-owned subsidiary of the corporation) directly or indirectly beneficially owning 15% or more of the outstanding voting stock of the corporation and any entity or person affiliated or associated with such entity or person.

For purposes of Delaware law, a “business combination” includes mergers, asset sales and other transactions resulting in financial benefit to a stockholder. This Delaware law could prohibit or delay mergers or other takeover or change of control attempts with respect to the Company and, accordingly, may discourage attempts that might result in a premium over the market price for the shares held by stockholders of the Company.
