RISK FACTORS

Investing in our common stock involves a substantial risk of loss. You should carefully consider these risk factors, together with all of the other information included in this prospectus or incorporated by reference herein, before you decide to purchase shares of our common stock. If any of the following risks occur, it could have a material adverse effect on our business, financial condition or results of operations. In that case, the trading price of our common stock could decline, and you could lose part or all of your investment. Some statements in this prospectus, including statements in the following risk factors, or in documents we have incorporated by reference, including statements in the section titled “Risk Factors” in our Annual Report, which is incorporated by reference in this prospectus, constitute forward-looking statements. See the section of this prospectus captioned “Special Note Regarding Forward-Looking Statements.”

Risks Related to Ownership of Our Common Stock

Although we are not a controlled company within the meaning of the Nasdaq rules, during the phase-in period we have relied and may continue to rely on exemptions from certain corporate governance requirements that provide protection to stockholders of other companies.

After the completion of our initial public offering, Oaktree Power Opportunities Fund IV (Delaware) Holdings, L.P. (“Oaktree Power”), Oaktree ATI Investors, L.P. (“Oaktree Investors” and, together with Oaktree Power, “Oaktree”) and Ron P. Corio controlled a majority of our common stock through Parent. Oaktree and Ron P. Corio are parties to a third amended and restated limited liability company agreement of Parent, as amended (the “LLC Agreement”) with Oaktree as holders of Class AA Preferred Units and Class A Common Units of Parent and Ron P. Corio as a holder of Class A Common Units of Parent, and pursuant to which they retain control of Parent. See “Certain Relationships and Related Party Transactions.”

As a result, we were a “controlled company” within the meaning of the Nasdaq corporate governance standards. Under the rules of Nasdaq, a company of which more than 50% of the outstanding voting power is held by an individual, group or another company is a “controlled company” and may elect not to comply with certain stock exchange corporate governance requirements, including:

Following the completion of our follow-on offering in December 2020 ( the “Initial Follow-on Offering”), we were no longer a controlled company under the Nasdaq listing requirements. Under the Nasdaq listing requirements, a company that ceases to be a controlled company must comply with the independent board committee requirements as they relate to the nominating and corporate governance and compensation committees on the following phase-in schedule: (1) one independent committee member at the time it ceases to be a controlled company, (2) a majority of independent committee members within 90 days of the date it ceases to be a controlled company and (3) all independent committee members within one year of the date it ceases to be a controlled company. Additionally, the Nasdaq listing requirements provide a 12-month phase-in period from the date a company ceases to be a controlled company to comply with the majority independent board requirement. During these phase-in periods, our stockholders will not have the same protections afforded to stockholders of companies of which the majority of directors are independent and, if, within the phase-in periods, we are not able to recruit additional directors who would qualify as independent, or otherwise comply with the Nasdaq listing requirements, we may be subject to enforcement actions by Nasdaq. In addition, a change in our board of directors and committee membership may result in a change in corporate strategy and operating philosophies, and may result in deviations from our current growth strategy.

We cannot assure you that our stock price will not decline or not be subject to significant volatility after this offering.

The market price of our common stock could be subject to significant fluctuations after this offering. The price of our stock may change in response to fluctuations in our results of operations in future periods and also may change in response to other factors, including factors specific to companies in our industry, many of which are beyond our control. As a result, our share price may experience significant volatility and may not necessarily reflect the value of our expected performance. Among other factors that could affect our stock price are:

Further, the stock markets have experienced extreme 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. In addition, the stock prices of many renewable energy companies have experienced wide fluctuations that have often been unrelated 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, interest rate changes or international currency fluctuations, may cause the market price of our common stock to decline.

We cannot assure you that you will be able to resell any of your shares of our common stock at or above the public offering price. The public offering price will be determined by negotiations between us and the representatives of the underwriters and may not be indicative of prices that will prevail in the trading market after this offering. If the market price of our common stock after this offering does not exceed the public offering price, you may not realize any return on your investment and may lose some or all of your investment.

The price of our common stock could decline if securities analysts cease to publish research or if securities analysts or other third parties publish inaccurate or unfavorable research about us.

The trading of our common stock is likely to be influenced by the reports and research that industry or securities analysts publish about us, our business, our market or our competitors. If one or more analysts downgrade our common stock or publish inaccurate or unfavorable research about our business, our stock price would likely decline. If one or more securities or industry analysts ceases to cover the Company or fails 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.

Future sales of our common stock, or the perception that such sales may occur, could depress our common stock price.

Sales of a substantial number of shares of our common stock in the public market following this offering, or the perception that such sales may occur, could depress the market price of our common stock. Our executive officers, directors and the selling stockholder have agreed with the underwriters in our IPO not to offer, sell, dispose of or hedge any shares of our common stock or any options or warrants to purchase any shares of our common stock, or securities convertible into, exchangeable for, or that represent the right to receive, shares of our common stock, subject to specified limited exceptions described elsewhere in this prospectus, during the period ending 30 days after the date of this prospectus, except with the prior written consent of Goldman Sachs & Co. LLC and J.P. Morgan Securities LLC. Prior to the closing of our IPO, we effected the Stock Split. Our certificate of incorporation authorizes us to issue up to 1,000,000,000 of our authorized shares of common stock, of which 126,994,467 shares of common stock is outstanding. All shares of our common stock (except 54,625,000 shares of common stock sold in our IPO, 36,656,250 shares of common stock sold in the Initial Follow-on Offering and the shares sold in this offering) are subject to the lock-up agreements or market stand-off provisions described under “Shares Available for Future Sale.” Shares of our common stock held by our affiliates will continue to be subject to the volume and other restrictions of Rule 144 under the Securities Act. See “Underwriting.”

Upon the completion of this offering, the holders of an aggregate of 4,658,246 shares of our common stock, based on shares of common stock outstanding as of December 31, 2020 and assuming no exercise of the underwriters’ option to purchase additional shares, or their transferees, will be entitled to rights with respect to the registration of their shares under the Securities Act. In addition, immediately following our IPO, we filed a registration statement registering under the Securities Act the shares of common stock reserved for issuance under the LTIP. See the information under the heading “Shares Available for Future Sale” for a more detailed description of the shares that will be available for future sales upon completion of this offering. Sales of our common stock pursuant to these registration rights or this registration statement may make it more difficult for us to sell equity securities in the future at a time and at a price that we deem appropriate. These sales also could cause our stock price to fall and make it more difficult for you to sell shares of our common stock.

DIVIDEND POLICY

We did not declare any cash distributions or dividendsground-mounting systems used in 2018, 2019 and 2020, except the Special Distribution, and we currently do not anticipate paying any cash distributions or dividends after this offering and for the foreseeable future. Instead, we anticipate that all of our earnings in the foreseeable future will be used to repay debt, for working capital, to support our operations and to finance the growth and development of our business. Any future determination relating to dividend policy will be made at the discretion of our board of directors and will depend on a number of factors, including restrictions in our current and future debt instruments, our future earnings, capital requirements, financial condition, prospects, and applicable Delaware law, which provides that dividends are only payable out of surplus or current net profits.

As a holding company, our ability to pay cash distributions or dividends depends on our receipt of cash distributions or dividends from our operating subsidiaries. Our ability to pay cash distributions or dividends will therefore be restricted as a result of restrictions on their ability to pay cash distributions or dividends to us, including under the agreements governing our existing and any future indebtedness. See “Risk Factors—Risks Related to Ownership of Our Common Stock” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Debt Obligations” in our Annual Report, which is incorporated by reference in this prospectus.

CAPITALIZATION

The following table sets forth our cash and cash equivalents and capitalization as of December 31, 2020.

You should read this table together with the sections of this prospectus captioned “Prospectus Summary—The Offering” and “Description of Capital Stock” and the sections captioned “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Selected Financial Data” and our consolidated financial statements and related notes included in our Annual Report, which is incorporated by reference in this prospectus.

INDUSTRY OVERVIEW

Solar Mounting Systems Market

Solar energy projects can be roof-mounted or ground-mounted. Roof-mounted systems typically have capacities of less than 1 MW and are connected directly to the end-user’s electrical system. Ground-mounted projects typically have capacities of at least 1 MW and are connected to the electricity grid. Ground-mounted solar energy projects represented 84%projects. Our principal product is an integrated system of steel supports, electric motors, gearboxes and 51% of the total solar generation capacity installed in the U.S. and internationally (excluding China), respectively, during 2020 according to IHS Markit. The structure that supports the solar panels and other related equipment used in the solar energy project iselectronic controllers commonly referred to as the mounting system. Ground-mounting systems can be trackers or fixed tilt. Tracker systemsa single-axis “tracker.” Trackers move solar panels throughout the day to maintain an optimal orientation to the sun, which significantly increases their powerenergy production. Fixed tilt systems do not move. According to IHS Markit, approximately 70% and 30% of all ground-mounted solar energy projects constructed in the U.S. and internationally (excluding China), respectively, during 2019 utilized trackers and an estimated 74% of U.S. ground-mounted solar energy projects utilized trackers in 2020. Trackers can be single-axis or dual-axis. Single-axis trackers rotate around one axis only and dual-axis trackers rotate around two axes. The overwhelming majority of trackers produced and sold globally are single-axis.

Demand for ground-mounting systems is driven by installations of new ground-mounted solar energy projects. Demand for our products and our competitors’ products is a function of the percentage of those new installations that use trackers as opposed to fixed-tilt mounting systems. A solar energy project that uses single-axis trackers costs approximately 7% more to build than a solar energy project that uses a fixed-tilt mounting system, but has a 22% lower LCOE according to BloombergNEF. Trackers typically represent between 10% and 15% of the total cost of a solar energy project based on information from BloombergNEF.

Historically, we have derived the majority of our revenues from the sale of trackers used in U.S. solar energy projects.

U.S. Solar Market

Solar is the fastest growing form of electricity generation in the U.S. From 2015 to 2020, annual installations of ground-mounted solar generation capacity in the U.S. grew at a compound annual growth rate of 28% and represented nearly 24% of all new generation over one megawatt brought online over the same time period, according to IHS Markit and the Federal Energy Regulatory Commission, respectively. We believe key drivers supporting continued growth in U.S. solar generation include:

U.S. Tracker Market

Trackers are the fastest growing ground-mounting system for solar in the U.S. From 2017 to 2019, U.S. installations of trackers for systems with more than one megawatt of capacity grew at a compound annual growth rate of 35%, approximately 1.5 times faster than the compound annual growth rate of installations of all ground-mounted solar generation over the same period, according to IHS Markit. Installations of trackers grew faster than the total installations of ground-mounted solar generation in the U.S. because the percentage of ground-mounted solar installations that used trackers increased from approximately 60% in 2017 to approximately 70% in 2019 and an estimated 74% in 2020, according to IHS Markit.

International Solar Market

Excluding China, the international market for ground-mounting systems for solar energy projects was more than four times larger than the U.S. market in 2019 according to IHS Markit. From 2014 to 2019, annual installations of ground-mounted solar generation capacity outside of the U.S. and China grew at a compound

annual growth rate of 35% according to IHS Markit. We believe key drivers supporting continued growth in international solar generation are similar to the U.S. and also include:

International Tracker Market

Excluding China, international installations of trackers for systems with more than one megawatt of capacity grew at a compound annual growth rate of 71%, approximately two times faster than the compound annual growth rate of installations of all ground-mounted solar generation from 2017 to 2019, according to IHS Markit.

We believe that the global demand for trackers is growing faster than the overall demand for mounting systems because solar energy projects that use trackers generate significantly more energy for only a modest increase in capital cost and therefore havedeliver a lower LCOELevelized Cost of Energy (“LCOE”) than projects that use “fixed tilt” mounting systems, which do not move. The vast majority of ground mounted solar systems in the U.S. use trackers.

Our trackers use a patented design that allows one motor to drive multiple rows of solar panels through articulated driveline joints. To avoid infringing on our U.S. patent, our competitors must use designs that we believe are inherently less efficient and reliable. For example, our largest competitor’s design requires one motor for each row of solar panels. As a study published byresult, we believe our products have greater reliability, lower installation costs, reduced maintenance requirements and competitive manufacturing costs. Our core U.S. patent on a linked-row, rotating gear drive system does not expire until February 5, 2030.

We sell our products to engineering, procurement and construction firms that build solar energy projects and to large solar developers, independent power producers and utilities, often under master supply agreements or multi-year procurement contracts.

We are a U.S. company and our headquarters and principal manufacturing facility are in Albuquerque, New Mexico.

Board of Directors

Our board of directors consists of eight individuals including one as chairman. Our board of directors has determined that Troy Alstead and Orlando D. Ashford are independent directors under the standards of Nasdaq.

Our certificate of incorporation, which became effective upon the consummation of our IPO, provides that our board of directors shall be divided into three classes of directors, with the classes to be as nearly equal in number as possible, and with the directors serving three-year terms. For further information, see the section entitled “Description of Capital Stock—Anti-Takeover Effects of Delaware Law, Our Certificate of Incorporation and Our Bylaws.” Our board of directors is divided among the three classes as follows:

Committees of Our Board of Directors

Our board of directors has established audit, compensation, and nominating and corporate governance committees. The composition, duties and responsibilities of these committees are set forth below. Our board of directors may from time to time establish certain other committees to facilitate the management of the Company.

Audit Committee

Our board of directors has established an audit committee which is responsible for, among other matters: (1) appointing, compensating, retaining, evaluating, terminating and overseeing our independent registered public accounting firm; (2) discussing with our independent registered public accounting firm its independence from us; (3) reviewing with our independent registered public accounting firm the matters required to be reviewed by applicable auditing requirements; (4) approving all audit and permissible non-audit services to be performed by our independent registered public accounting firm; (5) overseeing the financial reporting process and discussing with management and our independent registered public accounting firm the interim and annual financial statements that we file with the SEC; (6) reviewing and monitoring our internal controls, disclosure controls and procedures and compliance with legal and regulatory requirements; and (7) establishing procedures for the confidential anonymous submission of concerns regarding questionable accounting, internal controls, auditing and federal securities law matters.

Our audit committee consists of Troy Alstead, Orlando D. Ashford and Jason Lee, with Troy Alstead serving as chairman. Rule 10A-3 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and Nasdaq rules require us to have one independent audit committee member upon the listingshares of our common stock on Nasdaq,involves a majorityhigh degree of independent directors within 90 daysrisk. You should carefully consider all of the dateinformation contained in this prospectus and any subsequent prospectus supplement, including our financial statements and related notes, before deciding whether to purchase shares of listing and all independent audit committee members within one year of the date of listing. We intend to comply with the independence requirements within the time periods specified. Our board of directors has determined that Troy Alstead is an “audit committee financial expert” as defined by applicable SEC rules and has the requisite financial sophistication as defined under the applicable Nasdaq rules and regulations. Our board of directors adopted a written charter for the audit committee, available on our website.

Compensation Committee

Our board of directors has established a compensation committee which is responsible for,common stock. In particular, you should carefully consider, among other matters: (1) reviewing officerthings, the risks and executive compensation goals, policies, plans and programs; (2) reviewing and approving or recommending touncertainties discussed in Part I, Item 1A, “Risk Factors” in our board of directors orAnnual Report on Form 10-K for the independent directors, as applicable, the compensation of our directors, Chief Executive Officer and other executive officers; (3) reviewing and approving employment agreements and other similar arrangements between us and our officers and other key executives; and (4) appointing and overseeing any compensation consultants.

Our compensation committee consists of Orlando D. Ashford, Brad Forth and Troy Alstead, with Orlando D. Ashford serving as chairman. The composition of our compensation committee currently satisfy the requirements for independence under current rules and regulations of the SEC and Nasdaq, including Nasdaq’s phase-in schedule for a company ceasing to be a controlled company.

Each member of the compensation committee is also a non-employee director, as defined pursuant to Rule 16b-3 promulgated under the Exchange Act, and an outside director, as defined pursuant to Section 162(m)

Messrs. Fusaro’s and Krantz’s and Ms. MacVane’s annual base salaries for the 2020 Fiscal Year (prior to our IPO) and 2019 Fiscal Year were $480,000, $350,000 and $280,000, respectively, and their target annual bonuses were 100%, 40% and 40%, respectively, of their base salary.

The offer letters provide for certain severance benefits upon a resignation by the applicable executive for “good reason” or upon a termination by the Company without “cause.” Please see the section entitled “—Additional Narrative Disclosure—Potential Payments Upon Termination or Change in Control” below for more details regarding the severance benefits provided to our Named Executive Officers under the offer letters.

Long Term Incentive Compensation

We have historically offered long-term incentives to our Named Executive Officers through grants of restricted Class B Common Units in Parent. These Class B Common Unit awards are subject to time-based vesting requirements and are subject to accelerated vesting upon the occurrence of certain terminations of employment and certain change in control events. However, we do not anticipate that the consummation of this

offering or any of the related transactions will result in accelerated vesting of any of the Class B Common Units in Parent. See below under “—Additional Narrative Disclosure—Potential Payments Upon a Termination or Change in Control” for additional information regarding the circumstances that could result in accelerated vesting of these awards.

In connection with our IPO, Messrs. Fusaro and Krantz and Ms. MacVane received restricted stock unit grants under the LTIP in respect of 60,924, 23,760 and 25,740 shares, respectively, of the Company’s common stock. See below under “—Actions Taken in Connection with Our IPO-Restricted Stock Unit Grants” for additional information regarding these grants.

The following table reflects information regarding outstanding equity-based awards held by our Named Executive Officers as of December 31, 2020.

Additional Narrative Disclosure

Retirement Benefits

We have not maintained, and do not currently maintain, a defined benefit pension plan or nonqualified deferred compensation plan. We currently make available a retirement plan intended to provide benefits under Section 401(k) of the Code, pursuant to which employees, including the Named Executive Officers, can make voluntary pre-tax contributions. Prior to 2020, we matched 100% of elective deferrals up to 3% of compensation. We currently match 50% of elective deferrals up to 3% of compensation, plus 50% of elective deferrals over 3% of compensation but that do not exceed 5% of compensation. These matching contributions made (i) prior to 2020, vests ratably over a five-year period and (ii) in 2020, vest 100% on the second anniversary of the commencement of the participant’s employment. All contributions under the plan are subject to certain annual dollar limitations, which are periodically adjusted for changes in the cost of living.

Potential Payments Upon Termination or Change in Control

A Named Executive Officer’s outstanding, unvested Class B Common Units in Parent will become 100% vested upon a “sale of the company,” which is generally the sale of Parent (or any subsidiary of Parent that holds substantially all of the assets of Parent) pursuant to which an independent third party or parties acquire (i) equity securities of Parent (or its applicable subsidiary) possessing the voting power to elect a majority of the board of directors of Parent (or its applicable subsidiary) or (ii) all or substantially all of Parent’s (or its applicable subsidiary’s) assets.

Our Named Executive Officers’ offer letters provide that upon a termination by us for any reason other than for “cause” or upon a resignation by such executive for “good reason,” each as defined therein, subject to the execution and delivery of a fully effective release of claims in favor of the Company and continued compliance with applicable restrictive covenants, Mr. Fusaro will receive salary continuation payments for six months (15 months if such termination occurs within six months following the acquisition of a majority ownership interest in the Company by an entity or entities not under common control of its current owners) and Mr. Krantz and Ms. MacVane will receive a lump sum payment of equal to nine months of base salary. The offer letters also contain certain restrictive covenants, including provisions that create restrictions, with certain limitations, on our Named Executive Officers soliciting any customers, soliciting or hiring Company employees or inducing them to terminate their employment, or disparaging the Company, in each case, during the term of the executive’s employment with the Company and for the one-year period following termination of employment.

Mr. Fusaro’s offer letter generally provides that “good reason” means the following with respect to him: (i) a reduction without his consent in his Salary below the Salary in effect as of the date hereof, (ii) a relocation of his principal place of employment, without his consent, to a location more than fifty (50) miles from his then-current principal place of employment (it being understood and agreed, for the avoidance of doubt, that the relocation contemplated by Section 6 shall not constitute Good Reason), or (iii) a change in position or title without his consent; provided that, in any case, upon written notice from the executive of the existence of any such occurrence, the Company will have 30 days to cure such occurrence.

Mr. Krantz’s and Ms. MacVane’s offer letters generally provide that “cause” means one or more of the following with respect to the executive: (i) the commission of a felony or other crime involving moral turpitude or of any other act or omission involving dishonesty or fraud, (ii) reporting to work under the influence of alcohol or under the influence or in the possession of illegal drugs, (iii) substantial and repeated failure to perform duties after notice of such failure and, if curable, an opportunity to permanently cure such failure within 30 days of such notice, (iv) breach of fiduciary duty, gross negligence or willful misconduct, (v) a willful and material failure to observe policies or standards regarding employment practices (including nondiscrimination and sexual harassment policies) after notice of such failure and, if curable, an opportunity to permanently cure such failure within 30 days of such notice or (vi) any breach by the executive of any non-competition, non-solicitation, no-hire or confidentiality covenant between the executive and the Company or any Company affiliate or any material breach by the executive of any other provision of the executive’s offer letter or any other agreement between the executive and the Company or any Company affiliate, after notice of such breach and, if curable, an opportunity to permanently cure such breach within 30 days of such notice. Mr. Krantz’s and Ms. MacVane’s offer letters generally provide that “good reason” means the following with respect to the executive: (i) a material reduction in his Salary without his consent, or (ii) a relocation of his principal place of employment, without his consent, to a location more than 50 miles from his then-current principal place of employment; provided that, in any case, upon written notice from the executive of the existence of any such occurrence, the Company will have 30 days to cure such occurrence.

Actions Taken in Connection with Our IPO

Class B Common Units in Parent

In connection with our IPO, we amended the Class B Common Unit award agreement for each of our Named Executive Officers to provide that each Named Executive Officer’s Class B Common Units in Parent will become fully vested upon the termination of their employment by the Company without cause or by the Named Executive Officer for good reason.

Restricted Stock Unit Grants

In connection with the reinvestment by our Chairman, our Named Executive Officers and certain other employees described in “Certain Relationships and Related Party Transactions—Parent LLC Agreement,” we granted our Chairman, Named Executive Officers and these employees restricted stock units under the LTIP with respect to an aggregate of 175,834 sharesregistration of the Company’s common stock. These restricted stock unit awards vest ratably over three years, subjectselling stockholders’ shares and to indemnify the recipient’s continued employment or service.

Long-Term Incentive Plan

In order to incentivize our employees following the completion of our IPO, our board of directors adopted a long-term incentive plan (the “LTIP”), for employees, consultants and directors prior to the completion of our IPO. Our Named Executive Officers are eligible to participate in the LTIP, which became effective upon the consummation of our IPO. The LTIP provides for the grant of options, stock appreciation rights, restricted stock, restricted stock units, stock awards, dividend equivalents, other stock-based awards, cash awards and substitute awards intended to align the interests of service providers, including our Named Executive Officers, with those of our shareholders.

Subject to adjustment in the event ofselling stockholders against certain transactions or changes of capitalization in accordance with the LTIP, a total of 5% of the shares of common stock outstanding at the closing of our IPO (on a fully diluted basis) were initially reserved for issuance pursuant to awards under the LTIP. The total number of shares reserved for issuance under the LTIP will be increased on January 1 of each of the first 10 calendar years during the term of the LTIP, by the lesser of (i) 5% of the total number of shares of common stock outstanding on each December 31 immediately prior to the date of increase or (ii) such number of shares of the Company’s common stock determined by our board of directors or compensation committee.liabilities.

$45 million in respect of such interests, based on the initial public offering price of $22.00 per share. Our Chairman and our listed executive officers have reinvested, through the purchasedelivery of shares of our common stock approximately 50% (except with respect to Jeff Krantz, our Chief Commercial Officer, approximately 40%) of the after-tax value of the distributions they received in respect of their vested Class B Common Units. See “Executive Compensation—Actions Taken in Connection with Our IPO—Class B Common Units in Parent.” Based on the initial public offering price of $22.00 per share, such reinvestment resulted in our Chairman and our listed executive officers purchasing approximately 527,506 shares of our common stock. Following this offering, our Chairman and our listed executive officers will receive net proceeds of approximately $55 million in respect of their interests in Parent, based upon the last reported sale price of our common stock on March 15, 2021 of $35.35 per share.

Under the LLC Agreement, each member is required to vote its, his or her units in favor of a board of managers of Parent (the “Board of Managers”) consisting of (i) at least three representatives that Oaktree designates (the “Sponsor Managers”), (ii) so long as the Corio Group (as defined below) holds collectively not less than 10% of the aggregate outstanding convertible class A preferred units and class A common units, one representative that the Corio Group designates, and (iii) three additional representatives with significant experience in the solar industry, two of which shall be designated by the Board of Managers, and one of which shall be designated by the Corio Group and approved by Oaktree (each, an “Additional Manager”); provided, that no Additional Manager shall be an affiliate of Oaktree or the Corio Group. Additionally, Oaktree is entitled to designate one individual to act as an observer on the Board of Managers in addition to the Sponsor Managers. The “Corio Group” consists of Ron P. Corio, a non-employee member of our board of directors, his permitted transferees and family.

Additionally, under the LLC Agreement, if Oaktree sells its convertible class A preferred units or class A common units to a third party (disregarding sales transfers to employees of Parent, any member of Parent or their respective affiliates and certain other exceptions), the holders of the convertible class A preferred units or class A common units will have the option, but will not be required (except in the case of a change of control transaction of Parent), to participate in the sale and sell alongside Oaktree on a pro rata basis.

Ron P. Corio and Oaktree also each have special consent rights related to certain Parent actions. So long as the Corio Group holds collectively holds not less than ten percent (10%) of the aggregate outstanding (i) convertible class A preferred units (on an as converted basis) and (ii) class A common units, Parent will need the Corio Group’s prior consent to issue class B common units over 7% of the sum of the class A common units, class B common units and convertible class A preferred units (on an as converted basis) outstanding, pay salary or issue equity to Brad Forth other than class C common units, change the total managers of the Board of Managers, make any material changes to Parent’s or any of its subsidiary’s line of business or enter into a transaction with Oaktree or its affiliate. Parent will need the prior written consent of Oaktree to enter into any arrangements with the Corio Group except for customary and reasonable employment agreements.

Tax Receivable Agreement

Concurrent with the acquisition of the Patent LLC, Array Tech, Inc. (f/k/a Array Technologies, Inc.) entered into the Tax Receivable Agreement (the “Tax Receivable Agreement”) with Ron P. Corio, our indirect stockholder. The Tax Receivable Agreement requires that Array Tech, Inc. (f/k/a Array Technologies, Inc.) pay Ron P. Corio for a portion of certain federal, state, local and non-U.S. tax benefits that we actually realize (or are deemed to realize in certain circumstances) in taxable periods following the acquisition of the Patent LLC. The Tax Receivable Agreement is accounted for as contingent consideration and subsequent changes in fair value of the contingent liability are recognized in general and administrative in the Company’s consolidated statement of operations. The Tax Receivable Agreement is valued based on the future expected payments under the agreement. At December 31, 2020, the fair value of the Tax Receivable Agreement was $19.7 million.

Estimating the amount of payments that may be made under the Tax Receivable Agreement is by nature imprecise. The significant fair value inputs used to estimate the future expected Tax Receivable Agreementclose out short positions;

payments to Ron P. Corio include the timing of tax payments, a discount rate, book income projections, timing of expected adjustments to calculate taxable income and the projected rate of use for attributes defined in the Tax Receivable Agreement.

Payments made under the Tax Receivable Agreement consider our tax positions and are generally due within 125 days following the filing of our U.S. federal and state income tax returns under procedures described in the Tax Receivable Agreement. The current portion of the Tax Receivable Agreement liability is based on tax returns. The Tax Receivable Agreement will continue until all tax benefit payments have been made or the Company elects early termination under the terms described in the Tax Receivable Agreement (or the Tax Receivable Agreement is otherwise terminated pursuant to its terms).

As of December 31, 2020, the undiscounted future expected payments through December 31, under the Tax Receivable Agreement are as follows (in thousands):

in October 2020 and $15.9 million in December 2020. As a result of these payments, our earn-out liability has been paid in full.

Senior Secured Promissory Note

On August 22, 2018, High Desert Finance LLC, our wholly owned subsidiary, issued a $38.6 million Senior Secured Promissory Note (such Note, the “Senior Secured Promissory Note”) in favor of Ron P. Corio, our indirect stockholder, that was secured by the outstanding common stock of ATI Investment Holdings, Inc. The maturity due date of the Senior Secured Promissory Note was originally February 22, 2020 but was subsequently amended to extend the due date to September 22, 2020.

The Company paid the remaining outstanding balance and accrued interest on July 31, 2020 to settle the obligation with respect to the Senior Secured Promissory Note. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Debt Obligations” in our Annual Report, which is incorporated by reference in this prospectus.

Consent Fees

The Company incurred $2.2 million in consent fees with the former majority shareholder of Array to allow a carryback of post-acquisition net operating losses to pre-acquisition periods under the CARES Act.

Letter of Credit Fees

For the year ended December 31, 2019 and 2020, the Company paid Oaktree, a significant shareholder of Parent, $0.8 million and $0.3 million, respectively, for full reimbursement of expenses relating to letter of credit fees under our Senior ABL Facility. No additional interest or fees were paid to Oaktree in connection with its payment of such expenses. For a description of the Senior ABL Facility, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Debt Obligations” in our Annual Report, which is incorporated by reference in this prospectus.

Consulting Services

During January 2019, we paid Brad Forth, a member of the board of directors who had previously served as our chief executive officer, $0.2 million for consulting work in support of the chief executive officer transition.

Registration Rights Agreement

In connection with our IPO, we entered into a registration rights agreement, or the Registration Rights Agreement, with Oaktree, the Corio Group and certain members of our management. Subject to certain conditions, the Registration Rights Agreement provides Oaktree and the Corio Group with “long-form” demand registrations and “short-form” demand registration rights, as well as shelf registration rights. The Registration Rights Agreement also provides Oaktree, the Corio Group and certain members of our management with customary “piggyback” registration rights. The Registration Rights Agreement contains provisions that require the parties thereto to coordinate with one another with respect to sales of our common stock and will contain certain limitations on the ability of the members of our management party to the Registration Rights Agreement to offer, sell or otherwise disposebroker-dealers of shares of our common stock that are loaned or pledged to such broker-dealers;

DESCRIPTION OF CAPITAL STOCK

General

In connection with our IPO, we converted from a Delaware limited liability company into a Delaware corporation, by filing a certificate of conversion with the office of the Secretary of the State of Delaware, and changed our name from ATI Intermediate Holdings, LLC to Array Technologies, Inc. We also filed with the office of the Secretary of the State of Delaware our amended and restated certificate of incorporation (our “Certificate of Incorporation”) and adopted our bylaws (our “Bylaws”), effective upon the consummation of our IPO. Below is a summary of the material terms and provisions of our Certificate of Incorporation and our Bylaws affecting the rights of our stockholders upon the consummation of our IPO, as well as relevant provisions of Delaware law affecting the rights of our stockholders. This summary does not purport to be complete and is qualified in its entirety by the provisions of our Certificate of Incorporation, our Bylaws and the DGCL. Copies of our Certificate of Incorporation and Bylaws have been filed with the SEC as exhibits to the registration statement on Form S-1 filed on October 8, 2020. References in this section to the “Company,” “we,” “us” and “our” refer to Array Technologies, Inc. and not to any of its subsidiaries.

Authorized Capital

Our authorized capital stock consists of 1 billion shares of common stock, par value $0.001 per share, and 5,000,000 shares of preferred stock, par value $0.001 per share.

As of December 31, 2020, there were 126,994,467 shares of common stock outstanding.

Common Stock

Voting Rights. The holders of our common stock are entitled to one vote per share on all matters submitted to a vote of stockholders; provided, however, that, except as otherwise required by law, holders of common stock, as such, shall not be entitled to vote on any amendment to our Certificate of Incorporation that relates solely to the terms of one or more outstanding Series of preferred stock if the holders of such affected Series are entitled, either separately or together with the holders of one or more other such series, to vote thereon pursuant to our Certificate of Incorporation. Holders of our common stock do not have cumulative voting rights in the election of directors. Accordingly, the holders of a majority of the combined voting power of our common stock could, if they so choose, elect all the directors.

Dividend Rights. Holders common stock will be entitled to receive dividends if, as and when declared by our board of directors, out of our legally available assets, in cash, property, shares of our common stock or other securities, after payments of dividends required to be paid on outstanding preferred stock, if any.

Distributions in Connection with Mergers or Other Business Combinations. Upon a merger, consolidation or substantially similar transaction, holders of each class of common stock will be entitled to receive equal per share payments or distributions.

Liquidation Rights. Upon our liquidation, dissolution or winding up, any business combination or a sale or disposition of all or substantially all of our assets, the assets legally available for distribution to our stockholders will be distributable ratably among the holders of the common stock, subject to prior satisfaction of all outstanding debts and other liabilities and the payment of liquidation preferences, if any, on any outstanding preferred stock.

Other Matters. Our Certificate of Incorporation does not entitle holders of our common stock to preemptive or conversion rights or other subscription rights. There are no redemption or sinking fund provisions applicable to our common stock. All outstanding shares of our common stock are, and the shares of common stock offered in this offering will be, fully paid and non-assessable.

Authorized but Unissued Preferred Stock

Delaware law does not require stockholder approval for any issuance of authorized shares. However, the listing requirements of Nasdaq, which apply as long as our common stock is listed on Nasdaq, require stockholder approval of certain issuances equal to or exceeding 20% of the combined voting power of our common stock. These additional shares may be used for a variety of corporate purposes, including future public offerings to raise additional capital, acquisitions and employee benefit plans.

Unless required by law or by any stock exchange on which our common stock may be listed, the authorized shares of preferred stock will be available for issuance without further action by our stockholders. Our Certificate of Incorporation authorizes our board of directors to establish, from time to time, the number of shares to be included in each Series of preferred stock, and to fix the designation, powers, privileges, preferences, and relative participating, optional or other rights, if any, of the shares of each Series of preferred stock, and any of its qualifications, limitations or restrictions. Our board of directors may also increase or decrease the number of shares of any Series of preferred stock, but not below the number of shares of that Series of preferred stock then outstanding, without any further vote or action by the stockholders, without any vote or action by stockholders.

The existence of unissued and unreserved common stock or preferred stock may enable our board of directors to issue shares to persons friendly to current management, which could render more difficult or discourage an attempt to obtain control of the Company by means of a merger, tender offer, proxy contest or otherwise, and could thereby protect the continuity of our management and possibly deprive stockholders of opportunities to sell their shares of common stock at prices higher than prevailing market prices.

Indemnification and Limitations on Directors’ Liability

Section 145 of the DGCL grants each Delaware corporation the power to indemnify any person who is or was a director, officer, employee or agent of a corporation, against expenses, including attorneys’ fees, judgments, fines and amounts paid in settlement actually and reasonably incurred by him or her in connection with any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, other than an action by or in the right of the corporation, by reason of serving or having served in any such capacity, if he or she acted in good faith 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 or proceeding, had no reasonable cause to believe his or her conduct was unlawful. A Delaware corporation may similarly indemnify any such person in actions by or in the right of the corporation if he or she acted in good faith in a manner reasonably believed to be in, or not opposed to, the best interests of the corporation, except that no indemnification may be made in respect of any claim, issue or matter as to which the person shall have been adjudged to be liable to the corporation unless and only to the extent that the Delaware Court of Chancery or the court in which the action was brought determines that, despite adjudication of liability, but in view of all of the circumstances of the case, the person is fairly and reasonably entitled to indemnity for expenses which the Delaware Court of Chancery or other court shall deem proper.

Section 102(b)(7) of the DGCL enables a corporation in its certificate of incorporation, or an amendment thereto, to eliminate or limit the personal liability of a director to the corporation or its stockholders for monetary damages for violations of the director’s fiduciary duty as a director, except (i) for any breach of the director’s duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) pursuant to Section 174 of the DGCL (providing for director liability with respect to unlawful payment of dividends or unlawful stock purchases or redemptions) or (iv) for any transaction from which a director derived an improper personal benefit. Our Certificate of Incorporation provides for such limitation of liability.

Our Certificate of Incorporation and Bylaws indemnify our directors and officers to the full extent permitted by the DGCL and our Certificate of Incorporation also allows our board of directors to indemnify other employees. This indemnification extends to the payment of judgments in actions against officers and directors and to

reimbursement of amounts paid in settlement of such claims or actions and may apply to judgments in favor of the corporation or amounts paid in settlement to the corporation. This indemnification also extends to the payment of attorneys’ fees and expenses of officers and directors in suits against them where the officer or director acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the Company, and, with respect to any criminal action or proceeding, he or she had no reasonable cause to believe his or her conduct was unlawful. This right of indemnification is not exclusive of any right to which the officer or director may be entitled as a matter of law and shall extend and apply to the estates of deceased officers and directors.

We maintain a directors’ and officers’ insurance policy. The policy insures directors and officers against unindemnified losses arising from certain wrongful acts in their capacities as directors and officers and reimburses us for those losses for which we have lawfully indemnified the directors and officers. The policy contains various exclusions that are normal and customary for policies of this type.

We believe that the limitation of liability and indemnification provisions in our Certificate of Incorporation, Bylaws and insurance policies are necessary to attract and retain qualified directors and officers. However, these provisions may discourage derivative litigation against directors and officers, even though an action, if successful, might benefit us and other stockholders. Furthermore, a stockholder’s investment may be adversely affected to the extent we pay the costs of settlement and damage awards against directors and officers as required or allowed by these limitation of liability and indemnification provisions.

At present, there is no pending litigation or proceeding involving any of our directors, officers, employees or agents as to which indemnification is sought from us, nor are we aware of any threatened litigation or proceeding that may result in an indemnification claim.

Anti-Takeover Effects of Delaware Law, Our Certificate of Incorporation and Our Bylaws

Certain provisions of Delaware law, our Certificate of Incorporation and our Bylaws could make the acquisition of the Company more difficult and could delay, defer or prevent a tender offer or other takeover attempt that a stockholder might consider to be in its best interest, including takeover attempts that might result in the payment of a premium to stockholders over the market price for their shares. These provisions also may promote the continuity of our management by making it more difficult for a person to remove or change the incumbent members of our board of directors.

Authorized but Unissued Shares; Undesignated Preferred Stock. The authorized but unissued shares of our common stock will be available for future issuance without stockholder approval except as required by law or by any stock exchange on which our common stock may be listed. These additional shares may be utilized for a variety of corporate purposes, including future public offerings to raise additional capital, acquisitions and employee benefit plans. In addition, our board of directors may authorize, without stockholder approval, the issuance of undesignated preferred stock with voting rights or other rights or preferences designated from time to time by our board of directors. The existence of authorized but unissued shares of common stock or preferred stock may enable our board of directors to render more difficult or to discourage an attempt to obtain control of us by means of a merger, tender offer, proxy contest or otherwise.

Board Classification. Our Certificate of Incorporation provides that our board of directors is divided into three classes of directors, with the classes to be as nearly equal in number as possible, and with the directors serving three-year terms. As a result, approximately one-third of our board of directors are 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 of directors. Our Certificate of Incorporation and Bylaws provide that, subject to any rights of holders of preferred stock to elect additional directors under specified circumstances, the number of directors will be fixed from time to time exclusively pursuant to a resolution adopted by our board of directors.

No Cumulative Voting. Our Certificate of Incorporation provides that stockholders are not permitted to cumulate votes in the election of directors.

Special Meetings of Stockholders. Our Bylaws provide that special meetings of our stockholders may be called, prior to the date on which Oaktree Power, Oaktree Investors and each of their respective affiliates cease to beneficially own at least 50% of the outstanding shares of common stock (the “Trigger Event”), only by or at the direction of our board of directors or our Chairman at the request of holders of not less than a majority of the combined voting power of our common stock, and, from and after the Trigger Event, only by or at the direction of our board of directors or our Chairman. The Trigger Event occurred upon the completion of the Initial Follow-on Offering.

Stockholder Action by Written Consent. Pursuant to Section 228 of the DGCL, any action required to be taken at any annual or special meeting of the stockholders may be taken without a meeting, without prior notice and without a vote if a consent or consents in writing, setting forth the action so taken, is signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares of our stock entitled to vote thereon were present and voted, unless our certificate of incorporation provides otherwise. Our Certificate of Incorporation precludes stockholder action by written consent from and after the Trigger Event, which occurred upon the completion of the Initial Follow-on Offering.

Advance Notice Requirements for Stockholder Proposals and Nomination of Directors. Our Bylaws require stockholders seeking to bring business before an annual meeting of stockholders, or to nominate individuals for election as directors at an annual or special meeting of stockholders, to provide timely notice in writing. To be timely, a stockholder’s notice will need to be sent to and received by our Secretary both (1) at our principal executive offices by hand delivery, overnight courier service, or by certified or registered mail, return receipt required, and (2) by electronic mail, as provided in the Bylaws, no later than the close of business on the 90th day, nor earlier than the close of business on the 120th day, prior to the anniversary of the immediately preceding annual meeting of stockholders. However, in the event that the annual meeting is called for a date that is not within 30 days before or 70 days after the anniversary of the immediately preceding annual meeting of stockholders, or if no annual meeting was held in the preceding year, such notice will be timely only if received no earlier than the close of business on the 120th day prior to the annual meeting and no later than the close of business on the later of the 90th day prior to such annual meeting and the tenth day following the date on which a public announcement of the date of the annual meeting was made by us. Our Bylaws also specify requirements as to the form and content of a stockholder’s notice. These provisions may preclude our stockholders from bringing matters before our annual meeting of stockholders or from making nominations for directors at our meetings of stockholders. These provisions may also discourage or deter a potential acquiror from conducting a solicitation of proxies to elect the potential acquiror’s own slate of directors or otherwise attempting to obtain control of the Company.

Removal of Directors; Vacancies. Under the DGCL, unless otherwise provided in our Certificate of Incorporation, directors serving on a classified board may be removed by the stockholders only for cause. Our Certificate of Incorporation provides that from and after the Trigger Event, directors may only be removed for cause, and only by the affirmative vote of holders of at least 66 2/3% in voting power of all the then-outstanding shares of common stock of the Company entitled to vote thereon. In addition, our Certificate of Incorporation also provides that from and after the Trigger Event, any newly created directorship on our board of directors that results from an increase in the number of directors and any vacancy occurring in our board of directors may only be filled by a majority of the directors then in office, although less than a quorum, or by a sole remaining director (and not by the stockholders). The Trigger Event occurred upon the completion of the Initial Follow-on Offering.

Supermajority Provisions. Our Certificate of Incorporation and Bylaws provide that our board of directors is expressly authorized to alter, amend, rescind or repeal, in whole or in part, our Bylaws without a stockholder vote in any matter not inconsistent with Delaware law and our Certificate of Incorporation. From and after the Trigger

Event, which occurred upon the completion of the Initial Follow-on Offering, in addition to any vote of the holders of any class or series of capital stock of our Company required therein, our Bylaws or applicable law, any amendment, alteration, rescission or repeal of our Bylaws by our stockholders will require the affirmative vote of the holders of at least 66 2/3% in voting power of all the then-outstanding shares of stock of our Company entitled to vote thereon, voting together as a single class.

The DGCL provides generally that the affirmative vote of a majority of the outstanding shares entitled to vote thereon, voting together as a single class, is required to amend a corporation’s certificate of incorporation, unless the certificate of incorporation requires a greater percentage. Our Certificate of Incorporation provides that the following provisions in our Certificate of Incorporation may be amended, altered, repealed or rescinded only by the affirmative vote of the holders of at least 66 2/3% in voting power of all the then-outstanding shares of stock of our Company entitled to vote thereon, voting together as a single class:

Section 203 of the Delaware General Corporation Law. Section 203 of the DGCL provides that, subject to certain stated exceptions, a corporation may not engage in a business combination with any “interested stockholder” (as defined below) for a period of three years following the time that such stockholder became an interested stockholder, unless:

An “interested stockholder” is any person (other than the corporation and any direct or indirect majority-owned subsidiary) who owns 15% or more of the outstanding voting stock of the corporation or is an affiliate or associate of the corporation and was the owner of 15% or more of the outstanding voting stock of the corporation

at any time within the three-year period immediately prior to the date of determination, and the affiliates and associates of such person.

Under our Certificate of Incorporation, we opted out of Section 203 of the DGCL and are therefore not subject to Section 203.

SHARES AVAILABLE FOR FUTURE SALE

Future sales of shares of our common stock in the public market after this offering, and the availability of shares for future sale, could adversely affect the market prices prevailing from time to time. As described below, only a limited number of shares of common stock will be available for sale shortly after this offering due to contractual and legal restrictions on resale. Nonetheless, sales of substantial amounts of our common stock in the future, or the perception that these sales could occur, could adversely affect prevailing market prices for our common stock and could impair our future ability to raise equity capital.

As of December 31, 2020, a total of 126,994,467 shares of common stock were outstanding. All of the 54,625,000 shares of common stock sold in our IPO, 36,656,250 shares of common stock sold in the Initial Follow-on Offering and the shares sold in this offering are or will be, respectively, freely tradable in the public market without restriction or further registration under the Securities Act, unless these shares are held by “affiliates,” as that term is defined in Rule 144 under the Securities Act.

The outstanding shares of our common stock held by existing stockholders are deemed “restricted securities” as that term is defined under Rule 144. Restricted securities may be sold in the public market only if their offer and sale is registered under the Securities Act or if the offer and sale of those securities qualify for an exemption from registration, including exemptions provided by Rules 144 and 701 under the Securities Act, which are summarized below.

As a result of the lock-up agreements and market stand-off provisions described below and the provisions of Rules 144 or 701, and assuming no exercise of the underwriters’ option to purchase additional shares, the shares of our common stock that will be deemed “restricted securities” will be available for sale in the public market following the completion of this offering as follows:

Rule 144

In general, a person who has beneficially owned restricted shares of our common stock for at least six months would be entitled to sell their securities provided that (1) such person is not deemed to have been one of our affiliates at the time of, or at any time during the 90 days preceding, a sale, (2) we have been subject to the Exchange Act periodic reporting requirements for at least 90 days before the sale and (3) we are current in our Exchange Act reporting at the time of sale.

Persons who have beneficially owned restricted shares of our common stock for at least six months, but who are our affiliates at the time of, or any time during the 90 days preceding, a sale, would be subject to additional restrictions, by which such person would be entitled to sell within any three-month period only a number of securities that does not exceed the greater of either of the following:

Such sales by affiliates must also comply with the manner of sale, current public information and notice provisions of Rule 144.

Registration Statement on Form S-8

We filed a registration statement on Form S-8 upon the closing of our IPO, which became effective immediately upon filing, under the Securities Act to register all of the shares of common stock reserved for issuance under the LTIP. Shares covered by the Form S-8 will then be eligible for sale in the public markets, subject to vesting restrictions, any applicable lock-up agreements described below and Rule 144 limitations applicable to affiliates. All shares of our common stock (except 54,625,000 shares of common stock sold in our IPO, 36,656,250 shares of common stock sold in the Initial Follow-on Offering and the shares sold in this offering) will be subject to the lock-up agreements or market stand-off provisions described below.

Lock-up Agreements

In connection with this offering, we, our directors and officers, and the selling stockholder, have agreed with the underwriters that, for a period ending 30 days (or 60 days in the case of the company) after the date of the final prospectus relating to this offering, subject to certain exceptions, we and they will not, directly or indirectly, offer, sell, contract to sell, pledge, grant any option to purchase, make any short sale or otherwise dispose of or hedge any of our shares of common stock, or any options or warrants to purchase any shares of our common stock, or any securities convertible into, or exchangeable for or that represent the right to receive shares of our common stock. Goldman Sachs & Co. LLC and J.P. Morgan Securities LLC in their sole discretion, may at any time release all or any portion of the shares from the restrictions in such agreements.

The lock-up agreements do not contain any pre-established conditions to the waiver by Goldman Sachs & Co. LLC and J.P. Morgan Securities LLC of any terms of the lock-up agreements. Any determination to release shares subject to the lock-up agreements would be based on a number of factors at the time of determination, including but not necessarily limited to the market price of the common stock, the liquidity of the trading market for the common stock, general market conditions, the number of shares proposed to be sold and the timing, purpose and terms of the proposed sale.

Registration Rights

Upon the completion of this offering, the holders of an aggregate of 4,658,246 shares of our common stock, based on shares of common stock outstanding as of December 31, 2020 and assuming no exercise of the underwriters’ option to purchase additional shares, or their transferees, will be entitled to rights with respect to the registration of their shares of common stock under the Securities Act. Registration of these shares under the Securities Act will result in these shares becoming freely tradable immediately upon the effectiveness of such registration, subject to the restrictions of Rule 144. For a further description of these rights, see the section entitled “Certain Relationships and Related Party Transactions—Registration Rights Agreement.”
