EXPLANATORY NOTE

​

ProSomnus, Inc. (the “Company,” “ProSomnus,” “we,” “us,” or “our”) is filing this Amendment No. 1 on Form 10-K/A (this “Amendment No. 1”) to amend our Annual Report on Form 10-K for the year ended December 31, 2023, originally filed with the Securities and Exchange Commission (the “SEC”) on March 27, 2024 (the “Original Form 10-K”), solely to include the information required by Items 10 through 14 of Part III of Form 10-K. This information was previously omitted from the Original Form 10-K in reliance on General Instruction G(3) to Form 10-K, which permits the information in the above-referenced items to be incorporated in the Form 10-K by reference to our definitive proxy statement if such statement is filed no later than 120 days after our fiscal year-end.

​

In accordance with Rules 12b-15 and 13a-14 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), we have also amended Part IV, Item 15 to include currently dated certifications pursuant to Section 302 of the Sarbanes-Oxley Act of 2002 from our principal executive officers and principal financial and accounting officer. Because no financial statements have been included in this Amendment No. 1 and this Amendment No. 1 does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4 and 5 of the certifications have been omitted. Similarly, because no financial statements have been included in this Amendment No. 1, certifications pursuant to Section 906 of the Sarbanes-Oxley Act of 2002 have been omitted.

​

Except as described above, this Amendment No. 1 does not modify or update disclosure in, or exhibits to, the Original Form 10-K. Furthermore, this Amendment No. 1 does not change any previously reported financial results, nor does it reflect events occurring after the date of the Original Form 10-K. Information not affected by this Amendment No. 1 remains unchanged and reflects the disclosures made at the time the Original Form 10-K was filed. Accordingly, this Amendment No. 1 should be read in conjunction with the Original Form 10-K and our other filings with the SEC.

The board of directors may establish other committees as it deems necessary or appropriate from time to time.

​

In arriving at this determination, the Board examined each audit committee member’s scope of experience and the nature of their prior and current employment. The audit committee meets on at least a quarterly basis. Both the independent registered public accounting firm and management intend to periodically meet privately with our audit committee.

​

The audit committee assists the Board in monitoring the integrity of our financial statements, our compliance with legal and regulatory requirements, and the independence and performance of our internal and external auditors. The audit committee’s principal functions include:

In making this determination, our Board considered Mr. Johnson’s formal education, training, and previous experience in financial roles.

​

Compensation Committee

​

The members of the compensation committee are Ms. Rider (Chair), Mr. Johnson, and Mr. Hedge. Our Board has determined that each of the members will be an “independent director” as defined by the Nasdaq Listing Rules applicable to members of a compensation committee. The Board has determined that each of the members of the compensation committee is a non-employee director, as defined in Rule 16b-3 promulgated under the Exchange Act and satisfy the independence requirements of the Nasdaq. The compensation committee meets from time to time to consider matters for which approval by the committee is desirable or is required by law.

​

The compensation committee is responsible for establishing the compensation of senior management, including salaries, bonuses, termination arrangements, and other executive officer benefits as well as director compensation. The compensation committee also administers ProSomnus’s equity incentive plans. The compensation committee may also, in its sole discretion, retain or obtain the advice of a compensation consultant, legal counsel or other adviser and will be directly responsible for the appointment, compensation and oversight of the work of any such adviser. However, before engaging or receiving advice from a compensation consultant, external legal counsel or any other adviser, the compensation committee will consider the independence of each such adviser, including the factors required by the Nasdaq and the SEC.

Table of Contents

Nominating and Corporate Governance Committee

​

The members of the nominating and corporate governance committee are Mr. Pacelli (Chair), Ms. Rider and Mr. Hedge. Our Board has determined that each of the members will be an “independent director” as defined by the Nasdaq Listing Rules applicable to members of a nominating committee. The nominating and corporate governance committee meets from time to time to consider matters for which approval by the committee is desirable or is required by law.

​

The nominating and corporate governance committee will be responsible for overseeing the selection of persons to be nominated to serve on our Board. The nominating and corporate governance committee also will be responsible for developing a set of corporate governance policies and principles and recommending to our Board any changes to such policies and principles.

​

Board Composition

​

Our business and affairs are organized under the direction of our Board. The Board consists of seven members. Laing Rikkers serves as Executive Chair of the Board and Mr. Johnson serves as the Lead Independent Director. The primary responsibilities of the Board are to provide oversight, strategic guidance, counseling, and direction to ProSomnus’s management. The Board will meet on a regular basis and additionally as required.

​

In accordance with our amended and restated certificate of incorporation, our board of directors is divided into three classes, Class A, Class B and Class C, with members of each class serving staggered three-year terms. The directors are assigned to the following classes:

​

​

​

At each annual meeting of stockholders, the successors to directors whose terms then expire will be elected to serve from the time of election and qualification until the third annual meeting following their election and until their successors are duly elected and qualified. This classification of our board of directors may have the effect of delaying or preventing changes in our control or management.

​

​

Board Oversight of Risk

​

Our management has day-to-day responsibility for identifying risks facing us, including implementing suitable mitigating processes and controls, assessing risks in relation to Company strategies and objectives, and appropriately managing risks in a manner that serves the best interests of the Company, our stockholders, and other stakeholders. Our Board of Directors is responsible for ensuring that an appropriate culture of risk management exists within the Company and for setting the right “tone at the top,” overseeing our aggregate risk profile, and assisting management in addressing specific risks.

​

Generally, various committees of our Board of Directors oversee risks associated with their respective areas of responsibility and expertise. For example, our Audit Committee oversees, reviews and discusses with management and the independent auditor risks associated with our internal controls and procedures for financial reporting and the steps management has taken to monitor and mitigate those exposures; our Audit Committee also oversees the management of other risks, including those associated with credit risk, compliance with the United States Foreign Corrupt Practices Act of 1977 and cybersecurity. Our Compensation Committee oversees the management of risks associated with our compensation policies, plans and practices. Our Nominating and Corporate Governance Committee oversees the management of risks associated with director independence and Board of Directors composition and organization. Management and other employees report to the Board of Directors and/or relevant committee from time to time on risk-related issues.

​

Guidelines for Selecting Director Nominees

​

Candidates for nomination to our Board of Directors are selected by the Nominating and Corporate Governance Committee in accordance with the committee’s charter, and our Certificate of Incorporation and Bylaws. The Nominating and Corporate Governance Committee will evaluate all candidates in the same manner and using the same criteria, regardless of the source of the recommendation.

​

The Nominating and Corporate Governance Committee may retain recruiting professionals to assist in identifying and evaluating candidates for director nominees. The Nominating and Corporate Governance Committee considers factors such as character, integrity,

Table of Contents

judgment, diversity of experience (including age, gender, international background, race and professional experience), independence, area of expertise, corporate experience, length of service, potential conflicts of interest, other commitments and the like. The Nominating and Corporate Governance Committee considers the following minimum qualifications to be satisfied by any nominee to the Board of Directors: the highest personal and professional ethics and integrity; proven achievement and competence in the nominee’s field and the ability to exercise sound business judgment; skills that are complementary to those of the existing Board of Directors; the ability to assist and support management and make significant contributions to the Company’s success; and an understanding of the fiduciary responsibilities that is required of a member of the Board of Directors and the commitment of time and energy necessary to diligently carry out those responsibilities.

​

Based on the Nominating and Corporate Governance Committee’s recommendation, the Board of Directors selects director nominees and recommends them for election by our stockholders, and also fills any vacancies that may arise between annual meetings of stockholders.

​

The Nominating and Corporate Governance Committee will consider director candidates who are timely proposed by our stockholders in accordance with our Bylaws and other procedures established from time to time by the Nominating and Corporate Governance Committee.

​

Board Diversity

​

While we do not have a formal policy on diversity, our Board, as part of its review of potential director candidates, considers each candidate’s character, judgment, skill set, background, reputation, type and length of business experience, personal attributes, and a particular candidate’s contribution to that mix. While no particular criteria are assigned specific weights, the Board believes that the backgrounds and qualifications of our directors, as a group, should provide a composite mix of experience, knowledge, backgrounds and abilities that will allow our board of directors to be effective, collegial and responsive to the nature of our business and our needs, and satisfy the requirements of applicable the rules and regulations, including the rules and regulations of the SEC, Nasdaq, and the State of California.

​

 The following table provides information regarding the gender and demographic diversity of our directors, based on each director’s voluntary self-identified characteristics.

​

​

Code of Ethics

​

We have adopted a code of ethics that applies to all of our directors, officers and employees. A copy of ProSomnus’s code of ethics is available on its website. ProSomnus also intends to disclose future amendments to, or waivers of, its code of ethics, as and to the extent required by SEC regulations, on its website.

​

Compensation Committee Interlocks and Insider Participation

​

None of the members of the compensation committee was at any time one of ProSomnus’s officers or employees. None of ProSomnus’s executive officers currently serves, or has served during the last completed fiscal year, on the compensation committee or board of directors of any other entity that has one or more executive officers that will serve as a member of our board of directors or compensation committee.

​

Table of Contents

Shareholder and Interested Party Communications

​

Stockholders and interested parties may communicate with our board of directors, any committee chairperson or the non-management directors as a group by writing to the board or committee chairperson in care of ProSomnus, Inc., 5675 Gibraltar Drive, Pleasanton, CA 94588. Each communication will be forwarded, depending on the subject matter, to the board of directors, the appropriate committee chairperson or all non-management directors.

​

Limitations of Liability and Indemnification of Directors and Officers

​

The Delaware General Corporation Law authorizes corporations to limit or eliminate, subject to certain conditions, the personal liability of directors to corporations and their stockholders for monetary damages for breach of their fiduciary duties. Our amended and restated certificate of incorporation limits the liability of our directors to the fullest extent permitted by Delaware law.

​

We have purchased and intend to maintain director and officer liability insurance to cover liabilities our directors and officers may incur in connection with their services to the combined company, including matters arising under the Securities Act. Our amended and restated certificate of incorporation and by-laws also provide that we will indemnify our directors and officers to the fullest extent permitted by Delaware law. Our amended and restated by-laws further provide that we will indemnify any other person whom we have the power to indemnify under Delaware law. In addition, we have entered into customary indemnification agreements with each of our officers and directors.

​

There is no pending litigation or proceeding involving any of our directors, officers, employees or agents in which indemnification will be required or permitted. We are not aware of any threatened litigation or proceedings that may result in a claim for such indemnification.

​

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, executive officers or persons controlling the combined company, we have been informed that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

​

Director Attendance

​

Each director is strongly encouraged to attend each annual meeting of stockholders. All seven (7) of our directors who then served on the board of directors attended the 2023 annual meeting of our stockholders.

​

Our corporate governance guidelines provide that directors should be prepared for and attend Board meetings and actively participate in Board discussions. The Board met thirteen times in 2023. Each director attended at least 75% of all board and committee meetings for which the director was a member.

​

Delinquent Section 16(a) Reports

​

Section 16(a) of the Exchange Act requires the Company’s officers and directors, and persons who own more than 10% of our Common Stock, to file reports of securities ownership and changes in such ownership with the SEC. Based on our review of such filings and written representations from certain reporting persons that no Form 5 is required, we believe that during the fiscal year ended December 31, 2023, all directors, executive officers, and greater than 10% stockholders complied with all Section 16(a) filing requirements applicable to them on a timely basis, except for: a Form 3/A with respect to each of Laing Rikkers, Heather Rider, Steven Pacelli and William Johnson, each of which was filed on February 16, 2024 to rectify unintentional underreporting in her or his initial Form 3, each of which was initially filed on December 7, 2022.

​

Item 11. Executive Compensation

The following is a discussion and analysis of compensation arrangements of our named executive officers, or “NEOs.” This discussion contains forward looking statements that are based on our current plans, considerations, expectations and determinations regarding future compensation programs. Actual compensation programs that we adopt may differ materially from currently planned programs as summarized in this discussion. As an “emerging growth company” as defined in the JOBS Act, we are not required to include a Compensation Discussion and Analysis section and have elected to comply with the scaled disclosure requirements applicable to emerging growth companies.

We seek to ensure that the total compensation paid to our executive officers is reasonable and competitive. Compensation of our executives is structured around the achievement of individual performance and near-term corporate targets as well as long-term business objectives.

Retirement Plans

ProSomnus currently maintains a 401(k) plan for its employees, including named executives, who satisfy certain eligibility requirements. ProSomnus’s named executives are eligible to participate in its 401(k) plan on the same terms as other eligible employees. ProSomnus believes that providing a 401(k) plan enhances the desirability of its executive compensation package, and further incentivizes its employees, including named executives, to perform.

Employee Benefits

All of ProSomnus’s eligible employees, including named executives, may participate in its health and benefits plans, including:

ProSomnus believes the aforementioned benefits are necessary and appropriate to providing a competitive compensation package to eligible employees, including named executives.

Employment Agreements

We have employment agreements with Leonard Liptak, Chief Executive Officer; Brian Dow, Chief Financial Officer; and Sung Kim, Chief Technology Officer

The executives’ employment agreements provide for “at will” employment until terminated by the executive or the Company. The employment agreements may be terminated: by us upon death or disability, or with or without cause; by the executive with our without good reason; or terminated by mutual agreement. If the employment agreement is terminated by death or disability, we shall pay the executive or his or her estate any accrued salary, unpaid bonus, pro-rata bonus for the current year, and accrued and unused vacation benefits. If the employment agreement is terminated by us for cause, by the executive without good reason, or in mutual agreement, we

shall pay the executive any accrued salary, unpaid bonus, pro-rata bonus for the current year, and accrued and unused vacation benefits.

Such incentive compensation may take the form of cash or stock payments.

Director Independence

​

Based upon information requested from and provided by each director concerning his or her background, employment and affiliations, including family relationships, our Board of Directors has determined that none of Messrs. Hedge, Johnson, Orchard, and Pacelli and Ms. Rider, representing five of our seven directors, has or has had a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these directors is “independent” as that term is defined under the rules of The NASDAQ Stock Market.

​

Our Board of Directors also determined that the directors who comprise our Audit Committee, Compensation Committee, and Nominating and Corporate Governance Committee, satisfy the independence standards for those committees established by applicable SEC rules, including Rule 10A-3 of the Exchange Act, and the rules of The NASDAQ Stock Market. In making this determination, our Board of Directors considered the relationships that each non-employee director has or has had with our company and all other facts and circumstances that our Board of Directors deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each non-employee director.

​

The Board of Directors believes that the independence of the Board members satisfies the independence standards established by applicable SEC rules and the rules of The NASDAQ Stock Market.

Pre-Approval Policies and Procedures

The Audit Committee has established, and our Board of Directors has approved, a pre-approval policy that describes the permitted audit, audit-related, tax and other services to be provided by Marcum, the Company’s independent registered accounting firm. The policy requires that the Audit Committee pre-approve the audit and non-audit services performed by the independent registered accounting firm in order to assure that the provision of such services does not impair the firm’s independence.

Any requests for audit, audit-related, tax and other services that have not received general pre-approval must be submitted to the Audit Committee for specific pre-approval, irrespective of the amount, and cannot commence until such approval has been granted. Normally, pre-approval is provided at regularly scheduled meetings of the Audit Committee. However, the Audit Committee may delegate pre-approval authority to one or more of its members. The member or members to whom such authority is delegated shall report any pre-approval decisions to the Audit Committee at its next scheduled meeting. The Audit Committee does not delegate its responsibilities to pre-approve services performed by the independent registered accounting firm to management.
