All statements, other than statements of historical facts contained in this prospectus, incorporated by reference into this prospectus or in filings with the SEC and our public releases, including statements regarding our strategy, future financial condition, future operations, projected costs, prospects, plans, objectives of management and expected market growth, are forward-looking statements.

iii

We have based these forward-looking statements largely on our current expectations, estimates, forecasts and projections about future events and financial trends that we believe may affect our financial condition, results of operations, business strategy and financial needs. In light of the significant uncertainties in these forward-looking statements, you should not rely upon forward-looking statements as predictions of future events.

You should refer to the section titled “Risk Factors” for a discussion of important factors that may cause our actual results to differ materially from those expressed or implied by our forward-looking statements.

Risk Factors

Investing in our securities involves risks. Before making an investment decision, in addition to the risk factor included below, you should carefully consider the risks described under the caption “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2021 and in our Quarterly Reports on Form 10-Q for the quarterly periods ended March 31, 2022, June 30, 2022 and September 30, 2022, which are incorporated herein by reference, as well as other risk factors described under the caption “Risk Factors” included or incorporated by reference in the prospectus, including our other filings with the SEC, before making an investment decision.

Any of the risks described below and that we describe in the information incorporated herein by reference could cause our business, financial condition or operating results to suffer. The market price of our common stock could decline if one or more of these risks and uncertainties develop into actual events. You could lose all or part of your investment. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition or operating results. Some of the statements in this section of the prospectus are forward-looking statements. For more information, see the sections of this prospectus titled “Incorporation of Information by Reference” and “Special Note Regarding Forward-Looking Statements.”

We are a controlled company within the meaning of the Nasdaq listing standards, and, as a result, qualify for, and rely on, exemptions from certain corporate governance requirements. You may not have the same protections afforded to stockholders of companies that are subject to such requirements.

Patient Square Capital controls a majority of the voting power of our common stock. As a result, we are considered a “controlled company” within the meaning of the marketplace rules (the “Listing Rules”) of the Nasdaq Stock Market (“Nasdaq”). Under the Listing Rules, a company of which more than 50% of the voting power is held by an individual, a group or another company is a “controlled company”. For so long as we qualify as a controlled company, we may, at our sole election, rely upon the Listing Rules exemptions applicable to controlled companies, pursuant to which we are exempt from certain corporate governance requirements of Nasdaq, such as the requirements that our board of directors (the “Board”) have a majority of independent directors and that our compensation committee and nominating and corporate governance committee be composed entirely of independent directors. Accordingly, you may not have the same protections afforded to stockholders of companies that are subject to all of the corporate governance requirements of Nasdaq.

If we cease to be a “controlled company” in the future, we will be required to comply with the corporate governance requirements of the Nasdaq Listing Rules, which may require replacing a number of our directors. These and any other actions necessary to achieve compliance with such rules may increase our legal and administrative costs, will make some activities more difficult, time-consuming and costly and may also place additional strain on our personnel, systems and resources.

Future resales of common stock may cause the market price of our securities to drop significantly, even if our business is doing well.

Sales of a substantial number of shares of our common stock in the public market could occur at any time, including by the Selling Stockholder pursuant to the registration statement of which this prospectus is a part. These sales, or the perception in the market of such sales, could reduce the market price of our common stock and increase the volatility in the market price of our common stock. Further, the sale of a substantial portion of shares of our common stock could result in a change of control of us, which could impact the market price and liquidity of our common stock.

Use of Proceeds

We will not receive any proceeds from the sale of shares of common stock by the Selling Stockholder.

Board composition

Classified board of directors

Our Board is divided into three classes. Our Amended and Restated Certificate of Incorporation provides that each class will consist, as nearly as possible, of one-third of the total number of directors, and each class has a staggered, three-year term. Unless the Board determines that vacancies or newly created directorships created by increases in the number of directors shall be filled by the stockholders, and except as otherwise provided by law, vacancies and newly created directorships on the Board may be filled only by the affirmative vote of a majority of the remaining directors in office, even though less than a quorum. A director elected by the Board to fill a vacancy or a newly created directorship shall serve for the remainder of the full term of the class of directors in which the vacancy or newly created directorships occurred and until such director’s successor is elected and qualified.

The Board currently consists of seven directors, divided into the three following classes:

The division of our Board into three classes with staggered three-year terms may delay or prevent a change of our management or a change in control.

Independence of the Board of Directors

Patient Square Capital beneficially owns more than 50% of our outstanding voting securities and we are therefore a “controlled company” within the meaning of the Listing Rules. For so long as we qualify as a controlled company, we may, at our sole election, rely upon the Listing Rules exemptions applicable to controlled companies, pursuant to which we are exempt from certain corporate governance requirements of Nasdaq such as the requirements that our Board have a majority of independent directors and that our Compensation Committee and Nominating and Corporate Governance Committee be composed entirely of independent directors. The “controlled company” exemption does not modify the independence requirements for our audit committee, and we comply with the requirements of the SEC and the Listing Rules requiring that our audit committee be composed exclusively of independent directors.

Our Board has undertaken a review of the independence of each of our directors and considered whether any director has a material relationship with us that could compromise such individual’s ability to exercise independent judgment in carrying out their responsibilities. As a result of this review, our Board has determined that each of Katie Bayne, Don Spence and David Wu qualifies as “independent” in accordance with the Listing Rules.

Controlled Company Exemption

Patient Square Capital beneficially owns more than 50% of the combined voting power for the election of directors. As a result, we are a “controlled company” within the meaning of the Listing Rules. For so long as we qualify as a controlled company, we may, at our sole election, rely upon the Listing Rules exemptions applicable to controlled companies including, but not limited to, the following requirements:

Accordingly, you may not have the same protections afforded to stockholders of companies that are subject to all of these corporate governance requirements. In the event that we cease to be a “controlled company” and our shares continue to be listed on Nasdaq, we will be required to comply with these provisions within the applicable transition periods. See “Risk Factors—We are a controlled company within the meaning of the Nasdaq listing standards, and, as a result, qualify for, and may rely on, exemptions from certain corporate governance requirements. You may not have the same protections afforded to stockholders of companies that are subject to such requirements.”

Investors’ Rights Agreement

On June 24, 2022, we entered into an agreement (the “Note Purchase Agreement”) with the Selling Stockholder and Drivetrain Agency Services, LLC, as administrative agent and collateral agent (the “Administrative Agent”). Pursuant to the Note Purchase Agreement, we issued approximately $105.5 million in senior secured convertible notes (the “Notes”) convertible into shares of our common stock to the Selling Stockholder.

On June 24, 2022, in connection with the Note Purchase Agreement, we also entered into an Investors’ Rights Agreement (the “NPA Investors’ Rights Agreement”) with the Selling Stockholder, pursuant to which, among other things, the selling stockholder has the right to nominate a number of directors to our Board that is proportionate to the Selling Stockholder’s ownership of the Company, which will be rounded up to the nearest whole number (and shall in no event be less than one). The Selling Stockholder has the right to nominate six directors to our Board as of December 7, 2022. The Selling Stockholder has exercised its right to nominate three directors, Trit Garg, M.D., Karr Narula and Justin Sabet-Peyman. For additional information, see “Note Purchase Agreement—Investors’ Rights Agreement.”

Compensation Committee Interlocks and Insider Participation

None of the members of our Compensation Committee is currently, or has been at any time, one of our executive officers or employees. None of our executive officers currently serves, or has served during the last completed fiscal year, as a member of the board of directors or compensation committee of any entity that currently has, or has had during the last completed fiscal year, one or more executive officers serving as a member of our Board or on our Compensation Committee.

Leadership structure of the Board

Our Amended and Restated Bylaws and Corporate Governance Guidelines provide our Board with flexibility to combine or separate the positions of Chair of the Board and Chief Executive Officer and to implement a lead director in accordance with its determination regarding which structure would be in the best interests of our company. Currently, our Chief Executive Officer and Chair positions are separate. Our Board has separated the roles of Chief Executive Officer and Chair on the basis that such separation promotes independent and effective oversight of management, particularly on key issues such as long-term strategic planning and risk management. Furthermore, this separation provides for focused engagement between these two roles in their respective areas of responsibility, while still providing for collaborative participation.

Our Board has concluded that our current leadership structure is appropriate at this time. However, our Board will continue to periodically review our leadership structure and may make such changes in the future as it deems appropriate.

Role of board in risk oversight process

Risk assessment and oversight are an integral part of our governance and management processes. Our Board encourages management to promote a culture that incorporates risk management into our corporate strategy and day-to-day business operations. Management discusses strategic and operational risks at regular management meetings and conducts specific strategic planning and review sessions during the year that include a focused discussion and analysis of the risks facing us. Throughout the year, senior management reviews these risks with the Board at regular Board meetings as part of management presentations that focus on particular business functions, operations or strategies, and presents the steps taken by management to mitigate or eliminate such risks.

Our Board administers its risk oversight function directly, as well as through various standing committees of our Board that address risks inherent in their respective areas of oversight. While our Board is responsible for monitoring and assessing strategic risk exposure, our Audit Committee is responsible for overseeing our major financial risk exposures, as well as cybersecurity risks, and the steps our management has taken to monitor and control these exposures and risks. The Audit Committee also approves or disapproves any related person transactions. Our Nominating and Corporate Governance Committee monitors the effectiveness of our Corporate Governance Guidelines. Our Compensation Committee assesses and monitors whether any of our compensation policies and programs has the potential to encourage excessive risk-taking.

Board committees

Our Board of Directors has established an Audit Committee, a Compensation Committee, and a Nominating and Corporate Governance Committee. Our Board may establish other committees to facilitate the management of our business. The composition and functions of each committee are described below. Members serve on these committees until their resignation or until otherwise determined by our Board. Each of these committees operates under a written charter that satisfies the applicable rules and regulations of the SEC and the Listing Rules, and that has been approved by our Board. These written charters are available in the Investor Relations section of our website at https://ir.eargo.com/. Website addresses are provided as inactive textual references only. The information provided on or accessible through any website referenced in this prospectus is not a part of, and is not incorporated by any reference into, this prospectus.

Audit Committee

Our Audit Committee oversees our corporate accounting and financial reporting process. Among other matters, the Audit Committee:

Our Audit Committee consists of Katie Bayne, Don Spence and David Wu. Our Board has determined that all members are independent under the Listing Rules and Rule 10A-3(b)(1) of the Exchange Act. The chair of our Audit Committee is David Wu. Our Board has determined that Mr. Wu is an “audit committee financial expert” as such term is currently defined in Item 407(d)(5) of Regulation S-K. Our Board has also determined that each member of our Audit Committee can read and understand fundamental consolidated financial statements, in accordance with the Listing Rules.

Compensation Committee

Our Compensation Committee oversees policies relating to compensation and benefits of our officers and employees. The Compensation Committee reviews and approves or recommends corporate goals and objectives relevant to compensation of our executive officers (other than our Chief Executive Officer), evaluates the performance of these officers in light of those goals and objectives, and approves the compensation of these officers based on such evaluations. The Compensation Committee also reviews and approves or makes recommendations to our Board regarding the issuance of stock options and other awards under our stock plans to our executive officers (other than our Chief Executive Officer). The Compensation Committee reviews the performance of our Chief Executive Officer and makes recommendations to our Board with respect to his compensation, and our Board retains the authority to make compensation decisions relative to our Chief Executive Officer. The Compensation Committee reviews and evaluates, on an annual basis, the Compensation Committee charter and the Compensation Committee’s performance.

Our Compensation Committee consists of Trit Garg, M.D., Justin Sabet-Peyman and David Wu. We currently avail ourselves of the “controlled company” exemption under the Listing Rules, pursuant to which we are exempt from the requirement to have a compensation committee that is composed entirely of independent directors. No member of the Compensation Committee is, or was in 2021, an executive officer of the Company. The chair of our Compensation Committee is Mr. Sabet-Peyman.

Nominating and Corporate Governance Committee

The Nominating and Corporate Governance Committee is responsible for making recommendations to our Board regarding candidates for directorships and the size and composition of our Board. With the goal of developing a diverse, independent and highly qualified Board, the Nominating and Corporate Governance Committee evaluates candidates in accordance with the qualification standards and selection criteria set forth in our Corporate Governance Guidelines. Evaluations of candidates generally involve a review of background materials, internal discussions and interviews with selected identified candidates, as appropriate. Candidates for the Board are generally selected based on desired skills and experience in the context of the existing composition of the Board and needs of the Board and its committees at that time, including the requirements of applicable SEC rules and the Listing Rules and the Selling Stockholder’s rights to nominate directors under the NPA Investors’ Rights Agreement. When considering candidates for nomination, the Nominating and Corporate Governance Committee may take into consideration many factors, including, among other things, a candidate’s experience with corporate management, public company board membership, professional and academic experience, leadership skills, finance and accounting and/or executive compensation experience, and ability to devote adequate time and effort to responsibilities of the Board in the context of its existing composition.

We believe it is important to have a diverse Board and, as such, our Corporate Governance Guidelines provide for the consideration of candidates’ background, gender, age and ethnicity. Our Nominating and Corporate Governance Committee considers these and other factors as it oversees Board and committee evaluations. After completing its review and evaluation of director candidates, our Nominating and Corporate Governance Committee recommends nominees to our full Board for election. The Nominating and Corporate Governance Committee is also responsible for overseeing our corporate governance policies and making recommendations to our Board concerning governance matters, including assisting the Board in its assessment of the independence of our directors.

Our Nominating and Corporate Governance Committee consists of Katie Bayne, Trit Garg, M.D. and Justin Sabet-Peyman. We currently avail ourselves of the “controlled company” exemption under the Listing Rules, pursuant to which we are exempt from the requirement to have a nominating and corporate governance committee that is composed entirely of independent directors. The chair of our Nominating and Corporate Governance Committee is Mr. Sabet-Peyman.

Corporate Governance

Code of Business Conduct and Ethics

We have adopted a written code of business conduct and ethics that applies to all of our directors, officers and employees, including our principal executive officer, principal financial officer and principal accounting officer or controller, or persons performing similar functions, and agents and representatives. The code of business conduct and ethics contains general guidelines for conducting our business consistent with the highest standards of business ethics. The full text of our code of business conduct and ethics is available on our website at https://ir.eargo.com/. The Nominating and Corporate Governance Committee of our Board is responsible for overseeing our code of business conduct and ethics and any waivers applicable to any director, executive officer or employee. We intend to disclose any future amendments to certain provisions of our code of business conduct and ethics, or waivers of such provisions applicable to our directors, officers and employees, including our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions, and agents and representatives, on our website identified above or in public filings.

Corporate Governance Guidelines

We believe in sound corporate governance practices and have adopted formal Corporate Governance Guidelines to enhance our effectiveness. Our Board adopted these Corporate Governance Guidelines in order to ensure that it has the necessary practices in place to review and evaluate our business operations as needed and to make decisions that are independent of our management. The Corporate Governance Guidelines are also intended to align the interests of directors with those of our stockholders. The Corporate Governance Guidelines set forth the practices our Board follows with respect to Board and committee composition and selection, Board meetings and succession planning. The Corporate Governance Guidelines include the Board’s standards used in nominating director candidates, which include candidates who have a high level of personal and professional integrity, strong ethics and values and the ability to make mature business judgments. A copy of our Corporate Governance Guidelines is available in the Investor Relations section of our website at https://ir.eargo.com/.

Note Purchase Agreement

Overview

On June 24, 2022, we entered into an agreement (the “Note Purchase Agreement”) with the Selling Stockholder and Drivetrain Agency Services, LLC, as administrative agent and collateral agent (the “Administrative Agent”). Pursuant to the Note Purchase Agreement, we issued approximately $105.5 million in senior secured convertible notes (the “Notes”) convertible into shares of our common stock to the Selling Stockholder.

The shares of common stock being offered by the Selling Stockholder pursuant to this prospectus are the shares of common stock (the “Shares”) that were issued upon conversion of the Notes in November 2022.

Investors’ Rights Agreement

On June 24, 2022, in connection with the Note Purchase Agreement, we also entered into the NPA Investors’ Rights Agreement with the Selling Stockholder, pursuant to which, among other things, we granted the Selling Stockholder certain governance, information and other rights.

The Selling Stockholder has the right to nominate the number of directors (the “Investor Directors”) to our board of directors that is proportionate to the Selling Stockholder’s ownership of the Company, rounded up to the nearest whole number (and in no event be less than one). The Selling Stockholder has the right to nominate six directors to our Board given the size of our Board as of December 7, 2022. The Selling Stockholder has exercised its right to nominate three directors, Trit Garg, M.D., Karr Narula and Justin Sabet-Peyman.

We have entered into an indemnification agreement with each Investor Director (the “Indemnification Agreement”). The Indemnification Agreement generally requires us, among other things, to indemnify each Investor Director against certain liabilities that may arise by reason of their status or service as a director. The Indemnification Agreement also generally requires us to advance any expenses incurred by each Investor Director as a result of any proceeding against them as to which they could be indemnified. These indemnification provisions and the Indemnification Agreements may be sufficiently broad to permit indemnification of each Investor Director for liabilities, including reimbursement of expenses incurred, arising under the Securities Act of 1933, as amended (the “Securities Act”).

For additional information regarding the Indemnification Agreement, refer to the full text of the Indemnification Agreement, which is filed as Exhibit 10.21 to the registration statement of which this prospectus is a part and incorporated by reference herein.

For additional information regarding the NPA Investors’ Rights Agreement, refer to the full text of the NPA Investors’ Rights Agreement, which is filed as Exhibit 10.22 to the registration statement of which this prospectus is a part and incorporated by reference herein.

Registration Rights Agreement

One June 28, 2022, we and the Selling Stockholder also entered into a Registration Rights Agreement (the “Registration Rights Agreement”) pursuant to which, among other things, we granted the Selling Stockholder certain customary demand and piggyback registration rights. Under the Registration Rights Agreement, we agreed to use our reasonable best efforts to file a registration statement providing for the resale of the Shares within ten business days of the completion of the Rights Offering, and to maintain its effectiveness thereafter for so long as any registrable securities remain outstanding. We filed the registration statement of which this prospectus is a part pursuant to such agreement.

For additional information regarding the Registration Rights Agreement, refer to the full text of the Registration Rights Agreement, which is filed as Exhibit 10.23 to the registration statement of which this prospectus is a part and incorporated by reference herein.

Description of Our Capital Stock

The following summary describes our capital stock and the material provisions of our amended and restated certificate of incorporation, as amended (our “Amended and Restated Certificate of Incorporation”), our amended and restated bylaws (our “Amended and Restated Bylaws”), the amended and restated investors’ rights agreement (the “Original Investors’ Rights Agreement”) to which we and certain of our stockholders are parties, the NPA Investors’ Rights Agreement, the Registration Rights Agreement and the Delaware General Corporation Law. Because the following is only a summary, it does not contain all of the information that may be important to you. For a complete description, you should refer to the full text of our Amended and Restated Certificate of Incorporation, Amended and Restated Bylaws, the Original Investors’ Rights Agreement, the NPA Investors’ Rights Agreement and the Registration Rights Agreement, copies of which are filed as Exhibits 3.1, 3.2, 10.1, 10.22 and 10.23 to the registration statement of which this prospectus is a part and are incorporated by reference herein.

General

Our authorized capital stock consists of 450,000,000 shares of common stock, par value $0.0001 per share, and 5,000,000 shares of preferred stock, par value $0.0001 per share.

Common stock

Voting rights

Each holder of common stock is entitled to one vote for each share on all matters submitted to a vote of the stockholders, including the election of directors. Our stockholders do not have cumulative voting rights in the election of directors. Accordingly, holders of a majority of the voting shares are able to elect all of the directors.

Dividends

Subject to preferences that may be applicable to any then-outstanding preferred stock, holders of our common stock are entitled to receive ratably any dividends that our board of directors may declare out of funds legally available.

Liquidation

In the event of our liquidation, dissolution or winding up, holders of our common stock will be entitled to share ratably in the net assets legally available for distribution to stockholders after the payment of all of our debts and other liabilities, subject to the satisfaction of any liquidation preference granted to the holders of any then-outstanding shares of preferred stock.

Rights and preferences

Holders of our common stock have no preemptive or conversion rights, and there are no redemption or sinking fund provisions applicable to our common stock. The rights, preferences and privileges of the holders of our common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of our preferred stock that we may designate and issue in the future.

Preferred stock

Our board of directors has the authority, without further action by the stockholders, to issue up to 5,000,000 shares of preferred stock in one or more series, to establish from time to time the number of shares to be included in each such series, to fix the rights, preferences and privileges of the shares of each wholly unissued series and any qualifications, limitations or restrictions thereon and to increase or decrease the number of shares of any such series, but not below the number of shares of such series then outstanding.

Our board of directors may authorize the issuance of preferred stock with voting or conversion rights that could adversely affect the voting power or other rights of the holders of common stock. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions and other corporate purposes, could, among other things, have the effect of delaying, deferring or preventing a change in control of our company that may otherwise benefit holders of our common stock and may adversely affect the market price of the common stock and the voting and other rights of the holders of common stock.

Classified Board of Directors

Our Board is divided into three classes. Our Amended and Restated Certificate of Incorporation provides that each class will consist, as nearly as possible, of one-third of the total number of directors, and each class has a staggered, three-year term. For additional information, see “Management—Board composition—Classified board of directors.”

NPA Investors’ Rights Agreement

In connection with the Note Purchase Agreement, we entered into the NPA Investors’ Rights Agreement, pursuant to which we granted the Selling Stockholder certain governance, information and other rights. For additional information, see “Note Purchase Agreement – Investors’ Rights Agreement.”

Registration rights

Under our Original Investors’ Rights Agreement and Registration Rights Agreement, certain holders of shares of our common stock, or their transferees, have the right to require us to register their shares (the “registrable securities”) under the Securities Act so that those shares may be publicly resold, and the holders of these shares of common stock, or their transferees, have the right to include their shares in any registration statement we file, in each case as described below.

Original Investors’ Rights Agreement

Demand registration rights

Certain holders of our common stock are entitled to certain demand registration rights. Pursuant to the Original Investors’ Rights Agreement, beginning after April 13, 2021, the holders of at least 35% of such registrable securities may, on not more than two occasions, request that we register all or a portion of their shares, subject to certain specified exceptions.

Piggyback registration rights

In the event that we propose to register any of our securities under the Securities Act, either for our own account or for the account of other security holders, certain holders of registrable securities will be entitled to certain “piggyback” registration rights allowing them to include their shares in such registration, subject to specified conditions and limitations.

S-3 registration rights

Certain holders of shares of our common stock are entitled to certain Form S-3 registration rights. The holders of such registrable securities may, with respect to not more than two such registrations within any 12-month period, request that we register all or a portion of their shares on Form S-3 if we are qualified to file a registration statement on Form S-3, subject to specified exceptions. Such request for registration on Form S-3 must cover securities with an aggregate offering price to the public which equals or exceeds $1.0 million. The right to have such shares registered on Form S-3 is further subject to other specified conditions and limitations.

Registration Rights Agreement

Resale registration statement

Under the Registration Rights Agreement, we agreed to use reasonable best efforts to file within ten business days of the completion of the Rights Offering a registration statement on Form S-1 covering the sale or distribution of the Shares from time to time by the Selling Stockholder on a delayed or continuous basis under the Securities Act. We are required to use reasonable best efforts to cause such registration statement to be declared effective as promptly as practicable after the filing and maintain and update the registration statement, subject to the terms and conditions therein. We filed the registration statement of which this prospectus is a part pursuant to such agreement.

Demand registration rights

The Selling Stockholder holding the registrable securities under the Registration Rights Agreement is entitled to certain demand registration rights. The holders of a majority of such registrable securities may, on not more than four occasions per 12-month period, request that not less than $10 million of registrable securities be sold through an underwritten offering, subject to certain specified exceptions. Additionally, the Selling Stockholder may request that we amend or supplement any registration statement as may be necessary, subject to certain specified exceptions, to effect a sale or distribution.

Piggyback registration rights

In the event that we propose to register any of our securities under the Securities Act, either for our own account or for the account of other security holders, the Selling Stockholder will be entitled to certain “piggyback” registration rights allowing them to include their shares in such registration, subject to specified conditions and limitations.

Anti-takeover provisions of Delaware law and our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws

Section 203 of the Delaware General Corporation Law (the “DGCL”)

We are subject to Section 203 of the DGCL, which prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years after the date that such stockholder became an interested stockholder, with the following exceptions:

In general, Section 203 defines a “business combination” to include the following:

In general, Section 203 defines an “interested stockholder” as an entity or person who, together with the person’s affiliates and associates, beneficially owns, or within three years prior to the time of determination of interested stockholder status did own, 15% or more of the outstanding voting stock of the corporation.

The statute could prohibit or delay mergers or other takeover or change in control attempts and, accordingly, may discourage attempts to acquire us even though such a transaction may offer our stockholders the opportunity to sell their stock at a price above the prevailing market price.

Because our Board approved the Note Purchase Agreement and the related transactions contemplated thereby, which would have resulted in the Selling Stockholder becoming an “interested stockholder” following the Rights Offering, the limitations of Section 203 described above do not apply to a potential business combination with Patient Square Capital.

Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws

Among other things, our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws:

The amendment of any of these provisions, except for the provision making it possible for our board of directors to issue undesignated preferred stock, would require approval by the holders of at least 66 2/3% of the voting power of all of our then-outstanding common stock.

The combination of these provisions makes it more difficult for our existing stockholders to replace our board of directors as well as for another party to obtain control of us by replacing our board of directors. Because our board of directors has the power to retain and discharge our officers, these provisions could also make it more difficult for existing stockholders or another party to effect a change in management. In addition, the authorization of undesignated preferred stock makes it possible for our board of directors to issue preferred stock with voting or other rights or preferences that could impede the success of any attempt to effect a change in control of our company.

These provisions are intended to enhance the likelihood of continued stability in the composition of our board of directors and its policies and to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to reduce our vulnerability to hostile takeovers and to discourage certain tactics that may be used in proxy fights. However, such provisions could have the effect of discouraging others from making tender offers for our shares and may have the effect of delaying changes in control or management of our company. As a consequence, these provisions may also inhibit fluctuations in the market price of our stock that could result from actual or rumored takeover attempts. We believe that the benefits of these provisions, including increased protection of our potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure our company, outweigh the disadvantages of discouraging takeover proposals, because negotiation of takeover proposals could result in an improvement of their terms.

Choice of forum

Our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws provide that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware will be the exclusive forum for the following types of actions or proceedings under Delaware statutory or common law: any derivative action or proceeding brought on our behalf; any action asserting a claim of breach of fiduciary duty owed by any of our directors, officers or stockholders to us or to our stockholders; any action asserting a claim against us arising pursuant to the DGCL, our Amended and Restated Certificate of Incorporation or our Amended and Restated Bylaws (as either may be amended from time to time); or any action asserting a claim against us that is governed by the internal affairs doctrine. As a result, any action brought by any of our stockholders with regard to any of these matters will need to be filed in the Court of Chancery of the State of Delaware and cannot be filed in any other jurisdiction; provided that, the exclusive forum provision will not apply to suits brought to enforce any liability or duty created by the Securities Exchange Act of 1934, as amended (the “Exchange Act”) or any other claim for which the federal courts have exclusive jurisdiction; and provided further that, if and only if the Court of Chancery of the State of Delaware dismisses any such action for lack of subject matter jurisdiction, such action may be brought in another state or federal court sitting in the State of Delaware. Our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws also provide that the federal district courts of the United States of America will be the exclusive forum for the resolution of any complaint asserting a cause of action against us or any of our directors, officers, employees or agents and arising under the Securities Act.

If any action the subject matter of which is within the scope described above is filed in a court other than a court located within the State of Delaware, or a Foreign Action, in the name of any stockholder, such stockholder

shall be deemed to have consented to the personal jurisdiction of the state and federal courts located within the State of Delaware in connection with any action brought in any such court to enforce the applicable provisions of our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws and having service of process made upon such stockholder in any such action by service upon such stockholder’s counsel in the Foreign Action as agent for such stockholder. Although our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws contain the choice of forum provision described above, it is possible that a court could find that such a provision is inapplicable for a particular claim or action or that such provision is unenforceable.

This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or any of our directors, officers, other employees or stockholders, which may discourage lawsuits with respect to such claims, although our stockholders will not be deemed to have waived our compliance with federal securities laws and the rules and regulations thereunder.

Limitation on liability and indemnification

Our Amended and Restated Certificate of Incorporation and our Amended and Restated Bylaws limit our directors’ liability and provide that we may indemnify our directors and officers to the fullest extent permitted under the DGCL. The DGCL provides that directors of a corporation will not be personally liable for monetary damages for breach of their fiduciary duties as directors, except for liability for any:

These limitations of liability do not apply to liabilities arising under federal securities laws and do not affect the availability of equitable remedies such as injunctive relief or recession.

The DGCL and our Amended and Restated Bylaws provide that we will, in certain situations, indemnify our directors and officers and may indemnify other employees and other agents, to the fullest extent permitted by law. Any indemnified person is also entitled, subject to certain limitations, to advancement, direct payment or reimbursement of reasonable expenses (including attorneys’ fees and disbursements) in advance of the final disposition of the proceeding.

In addition, we have entered, and intend to continue to enter, into separate indemnification agreements with our directors, officers and certain other employees. These indemnification agreements, among other things, require us to indemnify our directors, officers and certain other employees for certain expenses, including attorneys’ fees, judgments, fines and settlement amounts incurred by a director, officer or other employee in any action or proceeding arising out of their services as a director, officer or employee of our company, or any other company or enterprise to which the person provides services at our request.

We maintain a directors’ and officers’ insurance policy pursuant to which our directors and officers are insured against liability for actions taken in their capacities as directors and officers. We believe that these provisions in our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws and these indemnification agreements are necessary to attract and retain qualified persons as directors, officers and other employees.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or control persons, in the opinion of the SEC, such indemnification is against public policy, as expressed in the Securities Act and is therefore unenforceable.

Transfer agent and registrar

The transfer agent and registrar for our common stock is American Stock Transfer & Trust Company, LLC. The transfer agent and registrar’s address is 6201 15^th Avenue, Brooklyn, New York 11219.

Plan of Distribution

The Selling Stockholder, which as used herein includes its permitted transferees, may, from time to time, sell, transfer or otherwise dispose of any or all of its shares on Nasdaq or any other stock exchange, market or trading facility on which such shares are 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 Stockholder may use any one or more of the following methods when disposing of its shares of our common stock:

The Selling Stockholder may, from time to time, pledge or grant a security interest in some or all of the shares of our common stock owned by it and, if it defaults in the performance of its secured obligations, the pledgees or secured parties may offer and sell their shares, 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 the pledgee, transferee or other successors in interest as selling stockholders under this prospectus. The Selling Stockholder also may transfer its shares in other circumstances, in which case the transferees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.

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

To facilitate an offering of the securities, certain persons participating in the offering may engage in transactions that stabilize, maintain, or otherwise affect the price of the securities. This may include over-allotments or short sales of the securities, which involves the sale by persons participating in the offering of more securities than we sold to them. In these circumstances, these persons would cover the over-allotments or short positions by making purchases in the open market or by exercising their over-allotment option. In addition, these persons may stabilize or maintain the price of the securities by bidding for or purchasing securities in the open market or by imposing penalty bids, whereby selling concessions allowed to dealers participating in the offering may be reclaimed if securities sold by them are repurchased in connection with stabilization transactions. The effect of these transactions may be to stabilize or maintain the market price of the securities at a level above that which might otherwise prevail in the open market. These transactions may be discontinued at any time.

The aggregate proceeds to the Selling Stockholder from the sale of the shares offered by it will be the purchase price of the shares less discounts or commissions, if any. The Selling Stockholder reserves the right to accept and, together with its agents from time to time, to reject, in whole or in part, any proposed purchase of its shares to be made directly or through agents. We will not receive any of the proceeds from the resale of shares of our common stock being offered by the Selling Stockholder named herein.

The Selling Stockholder may engage in at the market offerings into an existing trading market in accordance with Rule 415 of the Securities Act.

The Selling Stockholder also may resell all or a portion of its shares in open market transactions in reliance upon Rule 144 under the Securities Act (“Rule 144”), provided that they meet the criteria and conform to the requirements of that rule.

In connection with an underwritten offering, underwriters or agents may receive compensation in the form of discounts, concessions or commissions from the Selling Stockholder or from purchasers of the offered shares for whom they may act as agents. In addition, underwriters may sell the shares to or through dealers, and those dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from the purchasers for whom they may act as agents. The Selling Stockholder and any underwriters, dealers or agents participating in a distribution of the shares may be deemed to be “underwriters” within the meaning of the Securities Act, and any profit on the sale of the shares by the Selling Stockholder and any commissions received by broker-dealers may be deemed to be underwriting commissions under the Securities Act.

To the extent required, the shares of our common stock to be sold, the name of the Selling Stockholder, the respective purchase prices and public offering prices, the names of any agent, dealer or underwriter, 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, shares of our common stock may be sold in these jurisdictions only through registered or licensed brokers or dealers. In addition, in some states shares of our common stock 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.

If the Selling Stockholder wants to sell its shares of our common stock under this prospectus in the United States, the Selling Stockholder will also need to comply with state securities laws, also known as “Blue Sky laws,” with regard to secondary sales. All states offer a variety of exemption from registration for secondary sales. Many states, for example, have an exemption for secondary trading of securities registered under Section 12(g) of the Exchange Act or for securities of issuers that publish continuous disclosure of financial and non-financial information in a recognized securities manual, such as Standard & Poor’s. The broker for the Selling Stockholder will be able to advise the Selling Stockholder in which states shares of our common stock are exempt from registration for secondary sales.

Any person who purchases shares of our common stock from the Selling Stockholder offered by this prospectus who then wants to sell such shares will also have to comply with Blue Sky laws regarding secondary sales.

We have advised the Selling Stockholder 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 Stockholder and its affiliates. In addition, we will make copies of this prospectus (as it may be supplemented or amended from time to time) available to the Selling Stockholder for the purpose of satisfying the prospectus delivery requirements of the Securities Act. The Selling Stockholder may indemnify any broker-dealer that participates in transactions involving the sale of its shares against certain liabilities, including liabilities arising under the Securities Act.

We have agreed to indemnify, to the extent permitted by law, the Selling Stockholder (and the Selling Stockholder’s officers, directors, partners and members and each person who controls such Selling Stockholder within the meaning of the Securities Act), and each underwriter thereof, if any (and each person who controls such underwriter within the meaning of the Securities Act), against liabilities resulting from any untrue or alleged untrue statement of material fact contained in this prospectus or the registration statement of which this prospectus forms a part (including any amendment or supplement thereof), any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, or any violation by us of any rule or regulation promulgated under the Securities Act, Exchange Act or state securities laws applicable to us, except insofar as the same occurs in reliance upon and in conformity with written information furnished expressly for use herein by or on behalf of the Selling Stockholder regarding such Selling Stockholder.

We have also agreed to keep the registration statement of which this prospectus forms a part effective until the earlier of (i) the date on which all of the Selling Stockholder’s shares are disposed of pursuant to this prospectus; (ii) the date on which all of its shares have been sold pursuant to Rule 144 and none of the shares are restricted securities; (iii) the date on which such shares may be sold without registration pursuant to Rule 144 without volume or other restrictions; or (iv) the date on which all of its shares are transferred to a party other than a permitted transferee.

We will bear all costs, expenses and fees in connection with the registration of these shares of our common stock, including with regard to compliance with state securities or “blue sky” laws. The Selling Stockholder will bear all commissions and discounts, if any, attributable to its sale of shares of our common stock.

Information not required in prospectus

The following table sets forth the expenses payable by us in connection with the offering of securities described in this registration statement. All amounts shown are estimates, except for the SEC registration fee. We will bear all expenses shown below.

As permitted by Section 102 of the Delaware General Corporation Law (the “DGCL”), we have adopted provisions in our amended and restated certificate of incorporation, as amended (our “Amended and Restated Certificate of Incorporation”), and our amended and restated bylaws (our “Amended and Restated Bylaws”) that limit or eliminate the personal liability of our directors for a breach of their fiduciary duty of care as a director. The duty of care generally requires that, when acting on behalf of the corporation, directors exercise an informed business judgment based on all material information reasonably available to them. Consequently, a director will not be personally liable to us or our stockholders for monetary damages for breach of fiduciary duty as a director, except for liability for:

These limitations of liability do not affect the availability of equitable remedies such as injunctive relief or rescission. Our Amended and Restated Certificate of Incorporation also authorizes us to indemnify our officers, directors and other agents to the fullest extent permitted under Delaware law.

As permitted by Section 145 of the DGCL, our Amended and Restated Bylaws provide that:

Our Amended and Restated Certificate of Incorporation and our Amended and Restated Bylaws provide for the indemnification provisions described above and elsewhere herein. We have entered or will enter into, and intend to continue to enter into, separate indemnification agreements with our directors and officers that may be broader than the specific indemnification provisions contained in the DGCL. These indemnification agreements

II-1

generally require us, among other things, to indemnify our officers and directors against certain liabilities that may arise by reason of their status or service as directors or officers, other than liabilities arising from willful misconduct. These indemnification agreements also generally require us to advance any expenses incurred by the directors or officers as a result of any proceeding against them as to which they could be indemnified. These indemnification provisions and the indemnification agreements may be sufficiently broad to permit indemnification of our officers and directors for liabilities, including reimbursement of expenses incurred, arising under the Securities Act.

We have purchased and currently intend to maintain insurance on behalf of each and every person who is or was a director or officer of the company against any loss arising from any claim asserted against him or her and incurred by him or her in any such capacity, subject to certain exclusions.

Since September 30, 2016, we have made the following sales of unregistered securities:securities. On January 17, 2023, we effected a reverse stock split of our common stock at a ratio of 1-for-20.

Proportionate adjustments were made to the number of shares of common stock reserved for issuance and other share limits under our equity incentive plans and employee stock purchase plan, and to the number of shares underlying outstanding equity awards and the per share exercise price of outstanding options. The following historical information does not give effect to the 1-for-20 reverse stock split:
