Delinquent Section 16(a) Reports

Each of our directors and executive officers and any greater than 10% beneficial owners of our common stock is required to report to the SEC, by a specified date, his transactions involving our common stock. Based solely on a review of the reports filed electronically with the SEC and written representations that no other reports were required to be filed, we believe that, during 2022, all reports required by Section 16(a) were timely filed, except that the reports on Form 4 filed in early 2022 to report 2021 annual stock option grants to each of our non-employee directors were untimely due to an administrative oversight. Our non-employee directors at the time of those grants were Thomas F. Bumol, Ph.D., Thomas J. Cable, Peter A. Demopulos, M.D., Arnold C. Hanish, Leroy E. Hood, M.D., Ph.D., Rajiv Shah, M.D., Kurt Zumwalt and former director Ray Aspiri.

ITEM 11. EXECUTIVE COMPENSATION

Non-Employee Director Compensation

To attract and retain qualified non-employee candidates to serve on the board of directors, we utilize a combination of cash and equity-based incentive compensation. The significant amount of time that members of the board of directors expend in fulfilling their duties, as well as the skill level required of our directors, is evaluated in setting director compensation, along with director compensation levels at companies in our peer group. We also reimburse our directors for travel and incidental expenses incurred in the performance of their services for us. Our non-employee director compensation policy was updated by the board of directors in 2022 based on a recommendation by the compensation committee after reviewing an analysis of non-employee director compensation of our Peer Group (as defined below).

Our non-employee director compensation policy, as revised effective July 1, 2022, provides that a non-employee director is granted an option to purchase 30,000 shares of our common stock upon his or her initial appointment or election to the board of directors, subject to vesting in equal annual installments over a three-year period beginning on the date the director took office. In addition, on the date of each annual meeting of shareholders, each non-employee director who has served as a director for at least six months and who will continue to serve as a director after the annual meeting is granted an option to purchase 15,000 shares of our common stock that vests in full on the day prior to the date of the next annual meeting of shareholders. The per share exercise price for options granted to non-employee directors is equal to the closing public trading price of our common stock on the date of grant, and vesting is conditioned on the director’s continued service through the applicable vesting dates. Prior to July 1, 2022, a non-employee director was entitled to receive an option to purchase 15,000 shares of our common stock upon his or her initial appointment or election to the board of directors and an option to purchase 7,500 shares of our common stock on the date of each annual meeting of shareholders. In connection with the approval of the revisions to the non-employee director compensation policy increasing the annual option award from 7,500 to 15,000 shares of our common stock, our board of directors authorized a one-time grant of an additional option to purchase 7,500 shares of our common stock to each of our non-employee directors to bring the total number of option shares awarded to each non-employee director during 2022 to 15,000, consistent with the revised policy.

Under our current policy, each non-employee director receives an annual cash retainer of $50,000 for service on the board of directors, plus additional fees for committee service, as applicable. Committee fees are $10,000, $7,500, $5,000 and $5,000 per year for services as a non-chair member of the audit, compensation, nominating and governance, and scientific committees, respectively, while fees for the chairs of those committees are $20,000, $15,000, $10,000 and $10,000 per year, respectively. In addition, our lead independent director receives an annual retainer of $25,000 for his service in such capacity. Prior to July 1, 2022, each non-employee director received an annual cash retainer of $40,000 for service on the board of directors and our lead independent director received an annual retainer of $10,000 for his service in such capacity. Committee fees under our policy prior to July 1, 2022 were $7,500, $5,000, $4,000 and $4,000 per year for services as a non-chair member of the audit, compensation, nominating and governance, and scientific committees, respectively, while fees for the chairs of those committees were $15,000, $10,000, $7,500 and $7,500 per year, respectively.

Director fees are paid on a quarterly basis as earned on a prorated basis.

Executive Compensation

Compensation Discussion and Analysis

This Compensation Discussion and Analysis contains forward-looking statements that are based on our current plans, considerations, expectations and determinations regarding future compensation programs. The actual compensation programs that we adopt may differ materially from currently planned programs as summarized in this discussion.

This Compensation Discussion and Analysis provides an overview of our executive compensation philosophy, the overall objectives of our executive compensation program and the components of our compensation program for our named executive officers. This section also discusses our executive compensation process. When we refer to our named executive officers, we are referring to the following individuals, who were our only executive officers during 2022:

●

Gregory A. Demopulos, M.D., our president, chief executive officer and chairman of the board of directors, who is referred to as our CEO;

●

Michael A. Jacobsen, our vice president, finance, chief accounting officer and treasurer, who is referred to as our PFO; and

●

Peter B. Cancelmo, J.D., our vice president, general counsel and secretary.

We determine compensation for our named executive officers based on their ability to achieve operational goals that further our long-term business objectives and create sustainable long-term shareholder value in a cost-effective manner. We generally make adjustments to each element of compensation for our named executive officers on an annual basis in connection with approval of compensation adjustments for all eligible employees, although, in historical periods, compensation adjustments or the timing thereof have been affected by the availability of cash, the need to preserve capital or the achievement of significant corporate objectives.

In 2022, our compensation committee approved:

Table of Contents

●

base salary adjustments for our named executive officers, considering market competitiveness along with company and individual performance in 2021;

●

cash bonuses for our named executive officers on the basis of company and individual performance in 2021; and

●

stock option awards for all eligible employees, including our named executive officers, considering market competitiveness along with company and individual performance in 2021.

Executive Compensation Philosophy and Objectives

We operate in a highly competitive business environment, which is constantly reshaped by medical advances, frequent changes to market and regulatory requirements and the emergence of new competitive technologies. To thrive in this environment, we must work rapidly to create and refine new development programs and product candidates, drive product candidates toward commercialization, achieve commercial objectives and demonstrate an ability to quickly identify and capitalize on new business opportunities. To achieve these goals, we need a highly talented team of technical and business professionals.

We compete with many other companies in seeking to attract and retain a skilled management team. To meet this challenge, we have employed a compensation philosophy of offering our executive officers competitive compensation and benefits packages that are focused on the creation of long-term shareholder value and rewarding our executive officers for achieving our strategic objectives.

We orient our executive compensation program to:

●

provide total compensation opportunities that enable us to recruit and retain executives with the experience and skills needed to manage the growth of our company and lead us to the next stage of development;

●

establish a clear alignment between the interests of our executives and the interests of our shareholders;

●

reinforce a culture of ownership, excellence and urgency; and

●

create a direct and meaningful link between company business results, individual performance and compensation.

Executive Compensation-Setting Process

Role of the Compensation Committee

The compensation committee of our board of directors is responsible for establishing our executive compensation philosophy and administering our executive compensation program, as well as determining and approving the compensation for our executive officers. The compensation committee periodically reports to our board of directors on its deliberations and actions. The compensation committee, with the assistance of Compensia, Inc. (“Compensia”), its independent compensation consultant, reviews our executive compensation program, including our incentive compensation plans, to determine whether they are appropriate, properly coordinated and achieve their intended purposes. In addition to the services mentioned above, Compensia also recommends to our board of directors or compensation committee any modifications of our existing plans, or new plans or programs, from time to time as requested by our board of directors or compensation committee.

Role of Management

In carrying out its responsibilities, the compensation committee works with members of our management, including our CEO. Typically, our senior management assists the compensation committee and Compensia by providing information on company and individual performance, market data and management’s perspective and recommendations on compensation matters. Our CEO reviews data compiled by Compensia and our senior management and makes recommendations to the compensation committee regarding the compensation of our executive officers and significant employees. Our CEO does not make recommendations with respect to his own compensation and excuses himself from

Table of Contents

compensation committee meetings when his compensation is discussed. While the compensation committee solicits and reviews our CEO’s recommendations and proposals with respect to compensation-related matters and receives guidance from Compensia, the compensation committee makes its decisions independently and may consider factors and information other than our CEO’s recommendations and proposals.

Role of Compensation Consultant

The compensation committee is authorized to retain the services of compensation consultants and other advisors in connection with the discharge of its responsibilities. The compensation committee has engaged Compensia to assist it from time to time in assessing a set of executive compensation guiding principles, to evaluate the competitiveness of our executive officers’ compensation and to assist it in designing and implementing our executive compensation program. Compensia serves at the discretion of the compensation committee and provided certain advisory services to the compensation committee in 2022. Our compensation committee has evaluated Compensia’s independence using the factors specified by the SEC and Nasdaq listing standards and has determined that the work performed by Compensia in 2022 does not give rise to any conflict of interest.

Use of Competitive Data

To assess the competitiveness of our executive compensation program and current compensation levels and to assist it in setting compensation levels, the compensation committee refers to executive compensation data compiled from a peer group of comparable companies in our industry.

With Compensia’s assistance, our compensation committee developed this group (the “Peer Group”) in 2021 and used Peer Group data in connection with compensation decisions in 2022. Peer companies were selected for the Peer Group based on their comparability to Omeros in terms of stage of development, depth and diversity of pipeline programs, and revenue and market capitalization. The Peer Group is comprised of the following companies:

●

Aerie Pharmaceuticals, Inc.⁽¹⁾

●

Agios Pharmaceuticals, Inc.

●

ACADIA Pharmaceuticals, Inc.

●

Amicus Therapeutics, Inc.

●

Collegium Pharmaceutical, Inc.

●

Corcept Therapeutics Incorporated

●

Epizyme, Inc.⁽¹⁾

●

Esperion Therapeutics, Inc.

●

Global Blood Therapeutics, Inc.⁽¹⁾

●

MacroGenics, Inc.

Pacira BioSciences, Inc.

PTC Therapeutics, Inc.

●

Radius Health, Inc.⁽¹⁾

●

Supernus Pharmaceuticals, Inc.

●

Vanda Pharmaceuticals, Inc.

●

Zogenix, Inc.⁽¹⁾

(1)Subsequently acquired.

In addition to peer group and other data from Compensia, our compensation committee typically also refers to commercially available compensation survey data for relevant markets in connection with its compensation decisions. We are in the process of selecting an updated peer group to be used in connection with our 2023 executive compensation decisions.

Most Recent “Say-on-Pay” Vote

We conducted our most recent non-binding advisory shareholder vote (a so-called “say-on-pay” vote) on the compensation of our named executive officers at our 2020 Annual Meeting of Shareholders. At that meeting, over 95% of the votes cast were voted in favor of our executive compensation policies and practices, as disclosed in the proxy statement for the meeting. In retaining our general approach to executive compensation, our compensation committee is mindful of the support our shareholders have expressed for our compensation policies and practices when evaluating our executive compensation program, policies and practices.

We expect to conduct our next say-on-pay vote and the vote on the frequency of future say-on-pay votes at the 2023 Annual Meeting of Shareholders.

The following is a description of each component of our executive compensation program, the rationale for each component and how awards were determined in 2022.

Base Salary

The compensation committee reviews the base salaries of our named executive officers each year. In assessing these base salary levels, the compensation committee considers market competitiveness based on Peer Group and survey data, the executive officer’s past and expected future contributions to Omeros, his knowledge, experience and responsibilities and the relative base salaries and responsibilities of the other members of our senior management team.

In 2022, the compensation committee increased the base salaries of Dr. Demopulos, Mr. Jacobsen and Mr. Cancelmo after reviewing competitive market data as well as Peer Group data and considering the performance of our named executive officers and the company. The base salary increases were effective April 1, 2022. The new base salary rates for our named executive officers, following the salary increases, were as follows:

Table of Contents


Named Executive Officer		Adjusted 2022 Base Salary
Gregory A. Demopulos, M.D.		$890,590
Michael A. Jacobsen		$438,048
Peter B. Cancelmo, J.D.		$427,680

Annual Bonuses

Our compensation committee has the authority and discretion to award annual bonuses to our named executive officers. We believe bonuses provide an effective tool to motivate and retain our employees, including our named executive officers, and achieve our business objectives.

With respect to our payment of bonuses, the compensation committee generally establishes a target bonus amount for each named executive officer. This amount is calculated as a percentage of the named executive officer’s base salary and can range from 25% to 100% or more for an individual performance year. The target amounts are reviewed and revised as needed to align with competitive market compensation paid to similarly situated executives at the companies in the Peer Group and to properly address individual responsibilities and experience, internal pay equity and other factors. The extent to which bonuses are actually paid is determined at the discretion of the compensation committee based primarily upon an assessment of our achievement of the corporate performance objectives for the year, with consideration also being given to an assessment of each named executive officer’s individual performance and contribution to the achievement of our corporate performance objectives.

Preliminary performance objectives are established by the board of directors, with input from our named executive officers and other members of senior management, as corporate goals that reflect our business priorities for the year. For each performance year, the compensation committee, in consultation with the board of directors, reviews the corporate performance objectives to determine and confirm their appropriateness for use as performance measurements for purposes of named executive officer compensation. The objectives may be re-visited during the year and potentially restated in the event of significant changes in corporate strategy or the occurrence of significant corporate events. The compensation committee retains full discretion to adjust individual bonus awards upwards for exceptional performance and to otherwise adjust bonus awards upwards or downwards to respond to changes in competitive compensation or other factors not measured by corporate or individual performance in any given year. In addition, depending on the company’s cash position, the compensation committee has the discretion, after consulting with the board of directors and our CEO, to not pay cash bonuses to conserve cash and support ongoing development programs and commercialization efforts.

Corporate performance factors established in connection with compensation decisions for the 2021 performance year included objectives related to:

●

obtaining U.S. Food and Drug Administration (“FDA”) approval for and launching narsoplimab for Hematopoietic stem cell transplant-associated thrombotic microangiopathy (“HSCT-TMA”);

●

advancing clinical and pre-clinical development programs;

●

maintaining a sufficient cash position;

●

maintaining separate payment status for OMIDRIA;

●

growing OMIDRIA revenues; and

●

other strategic objectives.

In July 2022, our board of directors reviewed the corporate performance objectives established for 2021 and determined that the corporate performance objectives for 2021 had been achieved at the 80% level. In determining that the corporate objectives had been achieved at a level less than 100%, the board of directors noted that the objective to obtain FDA approval for narsoplimab in HSCT-TMA had not been achieved; however, the compensation committee also considered discretionary factors relevant to assessing achievement of that objective. In particular, the board of directors

Table of Contents

noted that Omeros had successfully filed a biologics license application for narsoplimab in HSCT-TMA and that FDA’s decision to issue a complete response letter with respect thereto was an unexpected outcome that was not within management’s control.

In September 2022, the compensation committee approved cash bonuses for our named executive officers. The cash bonuses awarded to Messrs. Jacobsen and Cancelmo were equal to 80% of their target bonus amounts, which were 25% of their 2021 base salaries for both Mr. Jacobsen and Mr. Cancelmo. Accordingly, Messrs. Jacobsen and Cancelmo received bonus payments of $81,120 and $77,760, respectively. In recognition of Dr. Demopulos’ leadership role in the achievement of the corporate performance objectives in 2021, particularly with respect to maintaining separate payment for OMIDRIA, achieving the substantial quarter-over-quarter growth in OMIDRIA revenues that positioned the product for an advantageous divestiture and ensured that we were adequately capitalized by year-end, as well as achieving identified clinical objectives associated with our narsoplimab, OMS906 and GPR174 programs, the compensation committee approved a cash bonus payment to Dr. Demopulos of $890,000.

Corporate objectives established for the 2022 performance year included, among other things, obtaining a more favorable outcome from an appeal of the FDA’s complete response letter regarding narsoplimab for HSCT-TMA, completing enrollment in our pivotal trial of narsoplimab for immunoglobulin A nephropathy, ARTEMIS-IgAN, to allow readout of proteinuria data during 2023, rapidly advancing our pipeline of earlier-stage complement inhibitors by completing multiple key clinical milestones in our OMS906 and OMS1029 programs, advancing development and filing patent applications relating to our immuno-oncology and other discovery-stage programs, strengthening our financial position by obtaining meaningful funding without diluting shareholders, and supporting the successful transition of OMIDRIA to Rayner Surgical, Inc., including by ensuring continued separate payment for OMIDRIA.

Bonus awards for the 2022 performance year have not yet been determined for our named executive officers and are expected to be considered by the compensation committee in conjunction with review of other elements of named executive officer compensation following the committee’s receipt and consideration of a refreshed analysis of executive pay from Compensia.

Equity Compensation

Historically, we have not applied a specific formula to determine the size of the equity awards that are granted to our executive officers. Instead, the compensation committee has exercised its judgment, taking into consideration, among other things, Peer Group data compiled by Compensia as well as company performance, an evaluation of the expected and actual performance of each named executive officer, each named executive officer’s responsibilities, experience, skills and contributions, the cash compensation received by each named executive officer, relative internal pay equity and market conditions. The compensation committee generally also considers the existing equity holdings of each named executive officer, including the current economic value of their unvested equity and the ability of these unvested holdings to satisfy our objectives of retaining and incentivizing our executive officers. Based on these factors, the compensation committee, with data received from Compensia and, with respect to Mr. Jacobsen and Mr. Cancelmo, input from the CEO, determines the size of each award at levels it considers appropriate to create a meaningful opportunity for reward predicated on the creation of long-term shareholder value. The compensation committee has historically granted equity awards to our named executive officers in the form of stock options, although it is authorized to grant other types of equity awards, including restricted stock and restricted stock units, and may do so in the future.

The compensation committee grants stock option awards on an annual basis. In September 2022, the compensation committee granted stock option awards to our employees, including our named executive officers. In determining the size of the stock option awards for the named executive officers, the compensation committee considered their individual performance and corporate milestones achieved in 2021, discussed above, as well as internal equity and related factors.

Historically, stock option awards granted by our compensation committee in connection with annual performance reviews vest in equal monthly installments over a four-year period. The per share exercise price for our stock option awards is equal to the fair market value of our common stock on the date of grant. The fair market value is the closing public trading price of our common stock on the date of grant or, if the equity award is granted on a day when the trading

Table of Contents

market for our common stock is closed, the closing public trading price on the most recent trading day prior to the date of grant.

The stock option awards granted to our named executive officers in September 2021 have an exercise price of $3.93 per share and vest in equal monthly installments over a four-year period commencing April 1, 2022. The stock option awards granted to our named executive officers in 2022 were as follows:


		Number of Shares of Common Stock
		Underlying Stock Option Awards
Named Executive Officer		Granted in 2022
Gregory A. Demopulos, M.D.		650,000
Michael A. Jacobsen		85,000
Peter B. Cancelmo, J.D.		80,000

Retirement and Other Benefits

We have established a broad-based tax-qualified Section 401(k) retirement savings plan for our employees, including our named executive officers, who satisfy certain eligibility requirements. Under this plan, participants may elect to make pre-tax contributions, or post-tax contributions under a Roth option, of up to 100% of their current compensation, not to exceed the applicable statutory income tax limitation (which was $20,500 in 2022, or $27,000 if over age 50). We have an annual matching program based on salary deferral contributions made by participants in the plan. The company contribution is a match of the amount participants contribute to the plan, up to 4% of their eligible earnings or a maximum employer match of $4,000 per year. Participants must be employed with the company at December 31 of each year to be eligible for the matching contribution. The matching contribution vests at 25% per year beginning upon the participant’s initial employment at the company. We intend for the plan to qualify under Section 401(a) of the Internal Revenue Code (the “Code”), so that deferral contributions by participants to the plan, and income earned on plan contributions, are not taxable to participants until withdrawn from the plan.

Additional benefits received by our employees, including our named executive officers, consist of medical, dental and vision benefits, medical and dependent care flexible spending accounts, short- and long-term disability insurance, accidental death and dismemberment insurance and basic life insurance coverage. These benefits are provided to our named executive officers on the same basis as to all of our full-time employees.

Perquisites and Other Personal Benefits

Historically, with the exception of parking expenses, we only have provided perquisites or other personal benefits to our CEO. Pursuant to the terms of his employment agreement, we pay certain expenses incurred by our CEO, including his medical malpractice insurance premiums and practice fees so that he may continue to practice medicine, as well as parking expenses and business-related information technology expenses. We believe that his ability to maintain his position as a practicing surgeon is beneficial to our corporate objectives including, for example, by providing him with insight in determining the strategic direction of the company as well as assisting in the establishment of relationships with key medical and other opinion leaders relevant to our drug programs and corporate strategies.

Currently, we do not view perquisites or other personal benefits as a significant component of our executive compensation program. In the future, however, we may provide such items in limited circumstances, such as when we believe it is appropriate to assist an individual in the performance of his or her duties, to make our executives more efficient and effective and for recruitment, motivation or retention purposes. All future practices with respect to significant perquisites or other personal benefits will be approved and subject to periodic review by the compensation committee.

Our named executive officers are not eligible to receive any tax “gross-ups” or other tax reimbursement payments.

Employment Agreement and Post-Employment Compensation

Except for our CEO, we do not have employment agreements with our named executive officers. For a summary of the material terms and conditions of the employment agreement with our CEO, see “Employment Agreement with Gregory A. Demopulos, M.D.” below. Our CEO’s current employment agreement, which was entered into in 2010, was deemed necessary by our compensation committee to provide a competitive compensation package to retain someone with his unique skill set and medical expertise. At the same time, the compensation committee was sensitive to the need to balance the market competitiveness with the financial limitations of a development-stage life sciences company.

As part of his compensation package, the CEO’s employment agreement includes certain severance obligations and other provisions that apply in the event of termination of his employment under specified circumstances, including following a change in control of our company. The compensation committee determined that these provisions were necessary to induce our CEO to limit his medical practice in exchange for the uncertainty of a demanding position in the company and were developed based on negotiations with our CEO. The compensation committee believes that these protections continue to serve a retention purpose and help our CEO maintain his focus on his duty to maximize shareholder value if there is a potential transaction that could involve a change in control of our company. For a summary of these provisions, see “Potential Payments upon Termination or Change in Control” below.

In addition, we provide all of our employees, including our named executive officers, with accelerated vesting benefits for their equity awards in the event of a change in control of the company. We have provided this benefit to encourage our employees to focus on their responsibilities and not be distracted by the potential effect of a change in control of our company on their employment status. For a summary of the material terms and conditions of these benefits, see “Potential Payments upon Termination or Change in Control” below.

Hedging and Pledging Policy

Under our insider trading policy, all of our employees, including our executive officers, as well as our directors are prohibited from engaging in short sales of our stock as well as in transactions in publicly traded options, such as puts and calls, or in other derivative securities with respect to our securities, with the exception of stock options and other securities issued pursuant to our compensatory benefit plans. This prohibition extends to any hedging or similar transaction designed to decrease the risks associated with holding our securities.

Our insider trading policy also prohibits our executive officers and directors from pledging our securities as collateral for loans or holding our securities in margin accounts in which the securities may be sold without the officer’s or director’s consent unless certain preclearance requirements and restrictions are satisfied including approval by our board of directors or the audit committee of the board of directors. As permitted by our insider trading policy, the disinterested members of our board of directors have approved an exception to this policy to permit our CEO to pledge certain shares of Omeros common stock as collateral under certain credit arrangements.

Tax and Accounting Considerations

Deductibility of Executive Compensation

As described above, the compensation committee believes that its primary responsibility is to provide a compensation program that enables us to attract, retain and motivate highly qualified and talented executive officers. Accordingly, while the compensation committee considers all cost elements of our executive compensation programs, the compensation committee may, in its judgment, authorize compensation payments that exceed the $1.0 million limit on deductible compensation under Section 162(m) of the Code when it believes that such payments are appropriate to attract, retain and reward executive talent and to promote our corporate objectives.

Taxation of “Parachute” Payments and Deferred Compensation

Sections 280G and 4999 of the Code provide that executive officers and directors who hold significant equity interests and certain other service providers may be subject to an excise tax if they receive payments or benefits in connection with a change in control of our company that exceeds certain prescribed limits, and that our company (or a

2022 Option Exercises and Stock Vested

Potential Payments upon Termination or Change in Control

Pursuant to our employment agreement with Dr. Demopulos we are required to make payments to him upon termination of his employment in the circumstances described below. In addition, under the terms of our equity incentive plans, all of our named executive officers and significant employees are entitled to acceleration of vesting of their option awards upon a merger or change in control under certain conditions or pursuant to terms and conditions as may be determined by the compensation committee according to such plans.

Employment Agreement with Gregory A. Demopulos, M.D.

Overview

We entered into an employment agreement with Dr. Demopulos dated April 7, 2010 related to his service as our president and chief executive officer. Pursuant to the terms of his employment agreement, Dr. Demopulos is an at-will employee and was entitled to receive an initial annual base salary of $600,000, which our compensation committee reviews at least annually. Effective as of April 1, 2022, Dr. Demopulos’ annual salary was increased to $890,590 from $856,337. We may not reduce Dr. Demopulos’ annual base salary without his consent. Dr. Demopulos is entitled to participate in awards under our equity compensation and/or equity incentive plans at a level and on terms commensurate with his position and responsibilities, and no less favorable than those applicable to chief executive officers of peer companies as reasonably determined by the compensation committee, taking into account the recommendation of our independent compensation consultants. Dr. Demopulos also is entitled to participate in any employee benefit and fringe benefit plans that we make available to our executive employees, such as our equity compensation plans, 401(k) plan, disability and life insurance and company-paid health insurance. We also have agreed to allow Dr. Demopulos to maintain his status as a board-eligible orthopedic and hand and microvascular surgeon, which includes his performance

Table of Contents

of surgical procedures on a limited basis and have agreed to pay related malpractice insurance and professional fees, which were $14,396 in 2022. We believe that Dr. Demopulos’ ability to maintain his standing as a practicing surgeon is beneficial to our corporate objectives including, for example, providing him with insight in determining the strategic direction of the company as well as assisting in the establishment of relationships with key medical and other opinion leaders relevant to our drug programs and corporate strategies.

The employment agreement prohibits Dr. Demopulos from carrying on any business or activity, directly or indirectly, in direct competition with us or soliciting our employees to terminate their employment with us or to work with one of our competitors during his employment and for a period of up to two years following termination of his employment. In addition, the employment agreement prohibits him from soliciting or attempting to influence any of our customers or clients to purchase products from our competitors rather than our products.

The compensation due to Dr. Demopulos pursuant to his employment agreement following termination of his employment with us varies depending upon the nature of the termination.

Termination Without Cause for Good Reason

Dr. Demopulos’ employment agreement provides that if we terminate his employment without “cause,” as defined below, or if he terminates his employment with us for “good reason,” as defined below, then until the earlier of (a) two years from the date of his termination and (b) his start date with a new employer that pays him an annual base salary at least equal to the annual base salary we paid to him prior to his termination (provided that if he terminates his employment for good reason because of a reduction in his annual base salary, then the annual base salary that will be measured will be the annual base salary we paid him prior to such reduction), we will be obligated to pay him on our regularly scheduled payroll dates on an annualized basis:

●

the annual base salary he was receiving as of his termination, provided that if he terminates his employment for good reason because of a reduction in his annual base salary, then the annual base salary we will be obligated to pay him will be his annual base salary in effect prior to such reduction; plus

●

the greater of (1) the average annual bonus paid or payable with respect to the preceding two calendar years and (2) any bonus he would have been entitled to in the year of his termination as determined by our board of directors in good faith.

In addition, if we terminate Dr. Demopulos’ employment without cause or if he terminates his employment with us for good reason, all of his unvested option awards will immediately vest and become exercisable until the maximum term of the respective option awards and all unvested restricted shares he holds, if any, will immediately vest. Dr. Demopulos and his eligible dependents may also continue to participate in all health plans we provide to our executive employees on the same terms as our employees for a period of up to two years from the date of his termination, unless his new employer provides comparable coverage.

“Cause” is defined under Dr. Demopulos’ employment agreement to mean:

●

his willful misconduct or gross negligence in the performance of his duties, including his refusal to comply in any material respect with the legal directives of our board of directors so long as such directives are not inconsistent with his position and duties, and such refusal to comply is not remedied within 10 working days after written notice from the board of directors;

●

dishonest or fraudulent conduct that materially discredits us, a deliberate attempt to do an injury to us or conduct that materially discredits us or is materially detrimental to our reputation, including conviction of a felony; or

●

his material breach, if incurable, of any element of his confidential information and invention assignment agreement with us, including without limitation, his theft or other misappropriation of our proprietary information.

Table of Contents

Dr. Demopulos may terminate his employment for “good reason” if he terminates his employment with us within 120 days of the occurrence of any of the following events:

●

any material diminution in his authority, duties or responsibilities;

●

any material diminution in his base salary;

●

we relocate his principal work location to a place that is more than 50 miles from our current location; or

●

we materially breach his employment agreement.

If any of the above events have occurred as a result of our action, we will have 30 days from notice of such event from Dr. Demopulos to remedy the situation, in which case Dr. Demopulos will not be entitled to terminate his employment for good reason related to the event.

If Dr. Demopulos’ employment had been terminated without cause or if he had terminated his employment with good reason on December 31, 2022, he would have been entitled to receive an annual base salary of $856,337 and an annual bonus amount of $882,500 (or any greater bonus amount to which he would have been entitled in 2022 as determined by our board of directors in good faith), payable on a bi-monthly basis over a period of up to two years from the date of termination. In addition, options to purchase a total of 479,178 shares would automatically vest upon his termination, though the exercise price of these option awards exceeds $2.26 per share, the closing trading price of our common stock on December 31, 2022.

Dr. Demopulos and his eligible dependents would also be entitled to participate in the health plans we provide to our employees for a period of up to two years from the date of his termination at an estimated cost to us of approximately $20,573.

Termination for Cause, Voluntary Termination, Death, or Disability

If we terminate Dr. Demopulos’ employment for cause, if he voluntarily terminates his employment with us other than for good reason, or if his employment is terminated as a result of his death or “disability,” as defined below, Dr. Demopulos will be entitled to receive payments for all earned but unpaid salary, bonuses and vacation time, but he will not be entitled to any severance benefits.

“Disability” is defined under Dr. Demopulos’ employment agreement as his inability to perform his duties as the result of his incapacity due to physical or mental illness, and such inability, which continues for at least 120 consecutive calendar days or 150 calendar days during any consecutive 12-month period, if shorter, after its commencement, is determined to be total and permanent by a physician selected by us and our insurers and acceptable to Dr. Demopulos.

2008 Equity Incentive Plan and 2017 Omnibus Incentive Compensation Plan

Under both the 2008 Equity Incentive Plan (the “2008 Plan”) and the 2017 Omnibus Incentive Compensation Plan (the “2017 Plan”), if there is no assumption or substitution of outstanding option awards or replacement of such awards with a comparable cash incentive program by the successor corporation in connection with a merger or “change in control” (as separately defined in each plan), the option awards will become fully vested and exercisable immediately prior to the change in control. In addition, under awards granted under each of the 2008 Plan and the 2017 Plan, if within 12 months following a change in control an employee, including Dr. Demopulos, Mr. Jacobsen or Mr. Cancelmo, is terminated without “cause” or as a result of a “constructive termination,” as such terms are defined below, any outstanding option awards held by him or her, as applicable, that we issued pursuant to the 2008 Plan or the 2017 Plan, as applicable, will become fully vested and exercisable. The amounts under these plans that our named executive officers would have received under each of these scenarios appear in the table below.

Table of Contents

The 2008 Plan or the equity award agreements thereunder define key terms relating to the change in control provisions as follows:

●

a “change in control” means a proposed sale of all or substantially all of our assets, or the merger of us with or into another corporation, or other change in control;

●

a termination for “cause” means a termination of an employee for any of the following reasons: (1) his or her willful failure to substantially perform his or her duties and responsibilities to us or a deliberate violation of a company policy; (2) his or her commission of any act of fraud, embezzlement, dishonesty or any other willful misconduct that has caused or is reasonably expected to result in material injury to us; (3) unauthorized use or disclosure by him or her of any proprietary information or trade secrets of ours or any other party to whom he or she owes an obligation of nondisclosure as a result of his or her relationship with us; or (4) his or her willful breach of any of his or her obligations under any written agreement or covenant with us; and

●

a “constructive termination” means the occurrence of any of the following events: (1) there is a material adverse change in an employee’s position causing such position to be of materially reduced stature or responsibility; (2) a reduction of more than 30% of an employee’s base compensation unless in connection with similar decreases of other similarly situated employees; or (3) an employee’s refusal to comply with our request to relocate to a facility or location more than 50 miles from our current location; provided that in order for an employee to be constructively terminated, he or she must voluntarily terminate his or her employment within 30 days of the applicable material change or reduction.

The 2017 Plan defines key terms relating to the merger or change in control provisions as follows:

●

a “change in control” means a sale of all or substantially all of our assets, or the merger of us with or into another corporation, or other change in control;

●

a termination for “cause” means a termination of the employment or consulting relationship with the company for any of the following reasons: (1) willful misconduct or gross negligence in performance of duties or material violation of company policy; (2) commission of any act of fraud, embezzlement, dishonesty or any other willful misconduct that has caused or is reasonably expected to result in material injury to us; (3) unauthorized use or disclosure of any proprietary information or trade secrets of ours or any other party to whom he or she owes an obligation of nondisclosure as a result of his or her relationship with us; or (4) willful breach of any of his or her obligations under any written agreement or covenant with us; and

●

a “constructive termination” means the employee’s termination of employment within 120 days of any of the following events: (1) any material diminution in the employee’s authority, duties or responsibilities; (2) any material diminution in base salary; (3) any change of more than 50 miles in the geographic location at which the employee must primarily perform services; and (4) any other action or inaction that constitutes a material breach by the company of an employment agreement with the employee; provided, however, that the employee must first provide the company with written notice specifying the foregoing occurrences within 90 days of such occurrence, and provide the company with an opportunity to cure the condition within 30 days of delivery of such notice.

Equity Acceleration upon a Change in Control

None of Dr. Demopulos, Mr. Jacobsen nor Mr. Cancelmo would have derived value from the acceleration of outstanding equity awards had a change in control (and certain other events, as applicable) occurred on December 31, 2022 based on the closing trading price of our common stock on December 31, 2022, which was lower than the exercise prices of the applicable stock option awards.

CEO Pay Ratio Disclosure

We are required by SEC rules and regulations to disclose the annual total compensation for our CEO and the median annual total compensation for our worldwide employee population excluding our CEO, and the ratio of annual total compensation for our CEO to the annual total compensation for our median employee. For 2022, we chose to use the same median employee that we identified for 2021, as permitted by SEC rules, because there has been no change in our employee population or employee compensation arrangements that we believe would significantly impact our pay ratio calculations.

To identify our median employee in 2021, we took the following steps:

1. We determined that, as of December 31, 2021, our employee population consisted of 211 individuals (excluding our CEO), all of whom reside in the U.S. This population consisted of our full-time, part-time and temporary employees employed with us as of the determination date.

2. To identify the “median employee” from our employee population, we used total W-2 compensation consistently applied to all employees included in the calculation. We annualized the compensation for employees who were not employed by us for all of 2021 for purposes of establishing the distribution of employee compensation within our population and identified the employee nearest the median of this distribution who was employed for the full year 2021 as our median employee. We did not use any statistical sampling techniques and did not make any cost of living adjustments in identifying our median employee.

To determine our median employee’s annual total compensation, we identified and calculated the elements of that employee’s compensation for 2022 in accordance with the requirements of Item 402(c)(2) of Regulation S-K. Based on this analysis, for 2022 the total compensation of our CEO was $3,728,686, as reported in the Summary Compensation Table above, and the total compensation of our median employee was $173,998. This results in a ratio of annual total CEO compensation to annual total median employee compensation of approximately 21.4 to 1.

Our reported CEO pay ratio is an estimate calculated in a manner consistent with SEC rules for identifying the median employee and determining the ratio of his or her compensation to that of our CEO. These rules permit companies to employ a wide range of methodologies, estimates and assumptions. CEO pay ratios reported by other companies, which may have used other permitted methodologies or assumptions, and which may have a significantly different work force structure from ours, are not necessarily comparable to our CEO pay ratio. Also, as noted above, the dollar amount of stock option awards included in the total compensation for our CEO and our median employee represent the grant date fair value of stock option awards as computed in accordance with FASB ASC Topic 718, using assumptions set forth in Note 13, Stock-Based Compensation, to our consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022. Realization of this compensation is dependent upon the price of our common stock at the time the stock options are exercised.

Our 2017 Plan provides for the grant of incentive and non-statutory stock options, restricted stock, restricted stock units, stock appreciation rights, performance units and performance shares to employees, directors and consultants and subsidiary corporations’ employees and consultants. The 2017 Plan replaced the 2008 Plan, and as a result we will not grant any new awards under the 2008 Plan. Any stock option awards granted under the 2008 Plan that were outstanding as of the effective date of the 2017 Plan remained in effect pursuant to their terms and, if the award is canceled or is repurchased, the shares underlying such award become available for grant under the 2017 Plan.

(2)	The 2008 Plan provided for the grant of incentive and non-statutory stock options, restricted stock, stock appreciation rights, performance units and performance shares to employees, directors and consultants and subsidiary corporations’ employees and consultants.

Security Ownership of Certain Beneficial Owners and Management

The following table sets forth certain information with respect to the beneficial ownership of our common stock at April 18, 2023, for: each person who we know beneficially owns more than five percent of our common stock; each of our directors; each of our named executive officers; and all of our directors and executive officers as a group.

We have determined beneficial ownership in accordance with the rules of the SEC. Except as indicated by the footnotes below, we believe, based on the information furnished to us, that the persons and entities named in the table below have sole voting and investment power with respect to all shares of common stock that they beneficially own, subject to applicable community property laws. Applicable percentage ownership is based on 62,828,765 shares of common stock outstanding at April 18, 2023. In computing the number of shares of common stock beneficially owned by a person and the percentage ownership of that person, we deemed to be outstanding all shares of common stock subject to options held by that person that are currently exercisable or will become exercisable within 60 days of April 18, 2023. We did not deem these shares outstanding, however, for the purpose of computing the percentage ownership of any other person.

Unless otherwise indicated, the address of each person who owns more than five percent of our common stock listed in the table below is c/o Omeros Corporation, The Omeros Building, 201 Elliott Avenue West, Seattle, Washington 98119.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR INDEPENDENCE

Transactions with Related Persons

We have adopted a written policy that prohibits our executive officers, directors and director nominees and principal shareholders, including their immediate family members, from entering into a related-party transaction with us without the approval of our audit committee. Any request for us to enter into a transaction with an executive officer, director or director nominee, principal shareholder, or any of such persons’ immediate family members, in which such party had, has or will have a direct or indirect material interest and where the amount involved exceeds $120,000, other than certain excluded transactions including those involving compensation for services provided to us as an executive officer or director, must be presented to our audit committee for review, consideration and approval. All of our directors and executive officers are required to report to our audit committee any such related-party transaction. In considering the proposed related-party transaction, our audit committee will consider the relevant facts and circumstances available and deemed relevant to the audit committee, including, whether the transaction is fair to us, whether there are business reasons to enter into the transaction and whether the terms of the transaction would be similar if the transaction did not involve a related party, whether the transaction would impair the independence of a non-employee director, the

Table of Contents

materiality of the transaction and whether the transaction would present an improper conflict of interest between us and the related party.

The following is a summary of transactions since January 1, 2021 to which we have been a party in which the amount involved exceeded $120,000 and in which any of our executive officers, directors or beneficial holders of more than five percent of our common stock had or will have a direct or indirect material interest, other than compensation arrangements which are described elsewhere in this report. We believe that the terms of such transactions are as favorable as those we could have obtained from parties not related to us.

Technology Transfer Agreements

We are party to technology transfer agreements with Gregory A. Demopulos, M.D. pursuant to which he irrevocably transferred to us all of his intellectual property rights in our early PharmacoSurgery^® platform and our former Chondroprotective program, for which we have suspended activity. Other than his rights as a shareholder, Dr. Demopulos has not retained any rights to our PharmacoSurgery platform or Chondroprotective program, except that if we file for liquidation under Chapter 7 of the U.S. Bankruptcy Code or voluntarily liquidate or dissolve, other than in connection with a merger, reorganization, consolidation or sale of assets, Dr. Demopulos and another individual have the right to repurchase the PharmacoSurgery and Chondroprotective intellectual property at their respective then-current fair market values.

Insurance Policies

In 2021 we purchased group insurance policies (i.e., medical, dental, vision, disability and life) for our employees through Group Solutions Northwest, LLC (Group Solutions), for which we paid policy premiums of approximately $4.5 million in 2021. Group Solutions received commissions from the sale of these policies of approximately $144,000, which comprised less than 10% of its 2021 revenues. The owner and chief executive officer of Group Solutions is Gary Aspiri, the son of Ray Aspiri, a former director. The audit committee evaluated this transaction and ratified and approved its terms, concluding that the premiums we pay, and the commissions that Group Solutions receives, are consistent with terms we could expect to obtain for comparable insurance coverage from an unrelated third party. The board of directors considered this transaction when evaluating Ray Aspiri’s independence under Nasdaq listing standards and applicable SEC rules and concluded that the transaction did not affect his status as an independent director or his ability to serve on the audit committee and compensation committee. Ray Aspiri did not participate in the proceedings of the audit committee or board of directors related to this transaction. He retired from our board of directors in October 2021.

Indemnification Agreements

We have entered and expect to continue to enter into agreements to indemnify our directors, executive officers and other employees as determined by the board of directors. With certain exceptions, these agreements provide for indemnification for expenses including, among other things, attorneys’ fees, judgments, fines and settlement amounts incurred by any of these individuals in any action or proceeding relating to their service to Omeros.

Director Independence

Our board of directors has determined that Dr. Bumol, Mr. Cable, Mr. Hanish, Dr. Hood, Dr. Shah and Mr. Zumwalt each meet the independence requirements under applicable listing standards of Nasdaq, as well as applicable rules promulgated by the SEC. The board of directors has determined that Gregory A. Demopulos and Peter A. Demopulos are not independent.
