2018 Stock Incentive Plan financial
"Our Compensation Committee establishes and regularly reviews our compensation philosophy and programs, exercises authority... and administers our 2018 Stock Incentive Plan (the “2018 Plan”)."
Pay Versus Performance financial
"Pay Versus Performance The Company’s principal executive officer (“PEO”) and our non-PEO named executive officers (“NEOs”) were as follows..."
Total Shareholder Return financial
"The following table sets forth information concerning... and our financial performance... including Total Shareholder Return ($) and Peer Group Total Shareholder Return ($)."
Total shareholder return is the overall gain an investor gets from owning a stock, combining changes in the share price plus any cash payouts like dividends, and assuming those payouts are reinvested in more shares. Investors use it like a single score that shows the true return on their investment—similar to checking both the growth of a savings account and the interest earned—to compare how well different companies or investments perform over time.
Incentive Stock Options financial
"Awards under the 2018 Plan may be granted in any one or all of the following forms: (i) Incentive Stock Options within the meaning of Section 422 of the Internal Revenue Code..."
Incentive stock options are a type of employee stock option that gives eligible workers the right to buy company shares at a fixed price later on, often below future market value. They matter to investors because they align employee incentives with company performance, can dilute existing ownership when exercised, and create potential tax advantages for option holders if certain holding-time rules are met — think of them as a coupon to buy stock at today’s price with extra tax rules attached.
Section 162(m) of the Code financial
"Section 162(m) of the Code generally disallows a tax deduction for compensation in excess of $1 million paid... to its chief executive officer and certain other “covered employees”."
change in control financial
"Under our severance and change in control plan... The following chart sets forth the amounts payable... Payment Due upon a Change in Control (1)."
A "change in control" occurs when the ownership or management of a company shifts significantly, such as through a merger, acquisition, or sale of a large part of its assets. This change can impact how the company is run and may influence its future direction. For investors, it matters because it can affect the company's stability, strategy, and value, often signaling potential changes in investment risk or opportunity.

File new certifications of our principal executive officer and principal financial officer as exhibits to this Amendment under Item 15 of Part IV hereof, pursuant to Rule

The role of the compensation committee in setting executive officer compensation
The Compensation Committee establishes and regularly reviews our compensation philosophy and programs, exercises authority with respect to the determination and payment of base and incentive compensation to our executive officers and administers our 2018 Stock Incentive Plan (the “2018 Plan”). Our Compensation Committee consists of three members of our Board, each of whom is independent as that term is defined in the Sarbanes-Oxley Act of 2002 and the rules and regulations that have been promulgated thereunder and under the Exchange Act, and in the applicable NASDAQ listing standards.
Compensation Discussion and Analysis
Executive officers
During 2025, our Board designated that our “executive officers” (as that term is defined in the rules and regulations under the Exchange Act) were our Chief Executive Officer (Richard J. Daly), our Chief Operating Officer and Chief Scientific Officer (Dr. Steven R. Miller), our Chief Financial Officer (Michael W. Kalb), our Chief Medical and Regulatory Officer (Dr. Gary Ingenito until his retirement in June 2025 and our Chief Medical Officer, Dr. William T. Andrews, who joined us in June 2025), our Chief Commercial Officer (Jeffrey Del Carmen), our Chief Compliance Officer and Chief Legal Officer (Brian Elsbernd), our Chief Strategy Officer (Dr. Preethi Sundaram), and our Chief Human Resources Officer (Gregg Russo).

Overview of executive officer compensation
In evaluating executive compensation, our Compensation Committee receives third-party data and analysis on market trends and competitive practices from its independent compensation consultant. The Compensation Committee also receives and considers the recommendations of our Chief Executive Officer with respect to goals and compensation of executive officers. Our Compensation Committee assesses the information it receives in accordance with its business judgment. Our Chief Executive Officer is not present when his compensation is discussed by the Compensation Committee.
Our Compensation Committee believes that our executive officers are instrumental to our success. To that end, our compensation program is designed around the following:
 
Pay Element
  
Form
  
Purpose
Base Salary    Cash (Fixed)    Provides a competitive level of compensation that reflects position responsibilities, strategic importance of the position, and individual experience.
Short-Term Incentive (Annual Bonus)   
Cash Bonus
(Percent Fixed)
   Provides a cash-based award that recognizes the achievement of annual goals and objectives supporting an annual business plan.
Long-Term Incentive    Equity (Variable)    Provides incentives for management to execute goals supporting long-term stockholder value creation and our ability to recruit, retain and motivate key executives.

We also offer health and other insurance benefits to each of our employees, including our executive officers, and the benefits available to our executive officers are equal to the benefits available to all employees. No other perquisite benefits are available to our executive officers.
Process of setting 2025 executive officer compensation
In the summer of 2024, the Compensation Committee engaged Mercer LLC (a business of Marsh McLennan), an independent compensation consultant, to provide advice and recommendations relating to our executive officer and director compensation arrangements for the 2025 fiscal year. Initially, Mercer assisted the Compensation Committee in determining an appropriate peer group to evaluate the Company’s executive officer and director compensation for alignment with governance and market best practices, and to provide recommendations as to an appropriate compensation philosophy to guide the Compensation Committee in determining executive officer base, bonus and equity compensation for 2025.
An updated peer group was selected by the Compensation Committee, with the advice of Mercer, in July 2024. The criteria used in determining the peer group were commercial stage companies with median annual revenues approximating 0.5 to 2.5 times our annual revenues. The peer group selected was as follows:
 
Acadia Pharmaceuticals Inc.    Amicus Therapeutics, Inc.
Amphastar Pharmaceuticals, Inc.    Ani Pharmaceuticals, Inc.
Apellis Pharmaceuticals, Inc.    BioCryst Pharmaceuticals, Inc.
Collegium Pharmaceutical, Inc.    Corcept Therapeutics Incorporated
Halozyme Therapeutics, Inc.    Harmony Biosciences Holdings, Inc.
Intra-Cellular
Therapies
, Inc.
   Ironwood Pharmaceuticals, Inc.
Pacira BioSciences, Inc.    PTC Therapeutics, Inc.
Supernus Pharmaceuticals, Inc.    Ultragenyx Pharmaceutical, Inc.
On November 13, 2024, Mercer presented their report to the Compensation Committee of the compensation payable to the executive officers in our peer group. Based on that information, on November 20, 2024, the Board, upon the recommendation of the Compensation Committee, set base compensation and a bonus target for 2025 for each executive officer, and granted stock options and restricted stock units to each executive officer for their 2025 performance.
Further, on February 13, 2025, the Compensation Committee established the corporate goals and objectives for the payment of 2025 cash bonuses to executive officers, as follows:
 
Objective
   Weight  
Achievement of total revenues in 2025 of at least $573.5 million, including FIRDAPSE
®
net revenues for 2025 of at least $362.9 million and AGAMREE
®
net product revenues for 2025 of at least $122.1 million
     40
Acquisition of a significant company or
de-risked
late-stage orphan asset before the end of 2025 including (i) identifying at least six strategic targets and completing confirmatory diligence on at least three targets, (ii) conducting a valuation analysis and submitting

     20

     15
  
 
 
 
     100
Thereafter, on November 13, 2025, the Compensation Committee met to consider cash bonus compensation for the Company’s executive officers for 2025 services based on the previously established corporate goals and objectives. The Compensation Committee reviewed each of the factors that had been established in early 2025 and determined that while not all goals were achieved in full, several were exceeded, and important steps were taken by management to mitigate issues that adversely affected the results in 2025 compared to the established goals.

Table of Contents
After considering all of these factors, the Compensation Committee determined that the management bonuses for 2025 performance should be set at 100% of each executive officer’s bonus target previously established by the Compensation Committee.
Finally, on November 20, 2025, the Board, upon recommendation of the Compensation Committee, granted stock options and RSUs to each of our executive officers for their 2026 services.
The base and bonus compensation for our Principal Executive Officer, Principal Financial Officer, and our three most highly compensated employees (our “Named Executive Officers”) for services during the fiscal years ended December 31, 2025, 2024 and 2023, as applicable, as well as the value of the stock option and RSU grants made to each such executive officer in 2025, 2024, and 2023, as applicable, are described in the following summary compensation table:

on a termination without “cause” or a termination for “good reason” of a designated executive, the executive will receive one year’s base salary, any accrued bonus prior to termination, 12 month accelerated vesting of stock options and other equity awards, and benefits continuation for one year; provided that the terminated executive agrees to not compete with the company during the period in which severance is paid;
 
   
upon a “change in control,” all outstanding stock options and other equity awards held by each designated executive that have not yet vested shall automatically vest; and
 
   
upon termination of a designated executive within one year of a “change in control,” the terminated executive will receive one year’s base salary, payment in full of any target bonus previously granted for the severance period, and benefits continuation for the severance period, again subject to the terminated executive agreeing not to compete with us during the period in which severance is paid.
As of the date of this Amendment, the Compensation Committee has designated that Mr. Daly, Mr. Kalb, Mr. Del Carmen, Mr. Elsbernd, Dr. Andrews, Dr. Miller, Dr. Sundaram, and Mr. Russo will receive benefits under the severance and change in control plan. Pursuant to the terms of the plan, once an executive has been designated to participate in the severance benefits afforded by the plan, the Compensation Committee cannot modify the plan as to that designated executive to eliminate any benefits or to modify the definitions used in the policy to the detriment of the designated executive, unless otherwise agreed to by the designated executive.

2018 Stock Incentive Plan
The 2018 Plan was approved by our board of directors in February 2018 and became effective in
May
2018 after its approval by our stockholders at our 2018 annual meeting of stockholders. Amendments adding additional shares to the 2018 Plan were approved by our stockholders at the 2020 annual meeting of stockholders, the 2021 annual meeting of stockholders, the 2023 annual meeting of stockholders, the 2024 annual meeting of stockholders and the 2025 annual meeting of stockholders The Board believes that based on the current configuration of the company, the Company should have sufficient shares available for the next one to two years.
Administration
The Compensation Committee of the Board administers the 2018 Plan and determines which persons will receive grants of awards and the type of award to be granted to such persons. The Compensation Committee will also interpret the provisions of the 2018 Plan and make all other determinations that it deems necessary or advisable for the administration of the 2018 Plan.
Eligibility to Participate in the 2018 Plan
All eligible individuals are able to participate in the 2018 Plan. Eligible individuals include our directors, officers, employees, independent contractors and consultants, as well as individuals who have accepted an offer of employment from us. As of the date of this Form
10-K/A,
six
non-employee
directors, eight executive officers, approximately 169 other employees, and one consultant are eligible to receive grants under the 2018 Plan.
Because benefits under the 2018 Plan will require future actions by the Compensation Committee and the fair market value of our common stock at various dates, it is not possible to determine the benefits that will be received by eligible individuals under the 2018 Plan, if any. The securities that are underlying grants of awards under the 2018 Plan is our common stock.
Form of Awards
Awards under the 2018 Plan may be granted in any one or all of the following forms: (i) Incentive Stock Options within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”), (ii) stock options that are not Incentive Stock Options
(“Non-Qualified
Stock Options”, unless otherwise noted herein, “Options” refers to both Incentive Stock Options and
Non-Qualified
Stock Options), (iii) the right to receive all or some portion of the increase in value of a fixed number of shares of the Company’s common stock (“Stock Appreciation Rights” or “SARs”), which may be awarded either in tandem with Options or on a stand-alone basis, (iv) shares of Common Stock that are restricted (“Restricted Shares”), (v) the right to receive shares of the Company’s common stock at the end of a specified period (“RSUs”), (vi) the right to receive a fixed number of shares of the Company’s common stock, or the cash equivalent, which is contingent on the achievement of certain performance goals (“Performance Shares”), and (vii) the right to receive a designated dollar value, or shares of the Company’s common stock of the equivalent value, which is contingent on the achievement of certain performance goals (“Performance Units”).
To date, the Company has only granted stock options and RSUs to its officers, directors, employees, and consultants, and has not utilized any of the other forms of stock-based compensation that are available for grant under the 2018 Plan. However, the Compensation Committee reserves the right to grant in the future stock-based compensation in the other forms available under the 2018 Plan.

Table of Contents
Stock Options
Options may be granted under the 2018 Plan for the purchase of shares of our common stock. The Compensation Committee may designate Options as either Incentive Stock Options or
Non-Qualified
Stock Options. The term of each Option granted will be determined by the Compensation Committee. However, no Incentive Stock Option will be exercisable more than ten years after the date it is granted, or in the case of an Incentive Stock Option granted to an employee owning more than 10% of the total combined voting power of all classes of stock of the Company (a “10% Stockholder”), more than five years after the date it is granted.
The purchase price per share under each Incentive Stock Option will be specified by the Compensation Committee, but in no event may it be less than 100% of the market price per share of our common stock on the date the Incentive Stock Option is granted. In the case of an Incentive Stock Option granted to a 10% Stockholder, the purchase price per share must not be less than 110% of the market price of our common stock on the date of grant.
Options may be exercised in whole or in part. Payment for such exercise must be made in cash or through the delivery to the Company of shares of common stock previously owned by the Option holder. The Compensation Committee, in its sole and absolute discretion, may allow other forms of payment.
Stock Appreciation Rights
Stock Appreciation Rights may be awarded by the Compensation Committee in such amounts and on such terms and conditions as the Compensation Committee shall determine, in its sole and absolute discretion. The terms and conditions of any Stock Appreciation Right shall be substantially identical to the terms and conditions that would apply if the grant of such Stock Appreciation Right had been the grant of an Option.
Upon exercise of a Stock Appreciation Right, the owner of such Stock Appreciation Right shall be entitled to receive payment in cash, in shares of common stock, or a combination thereof, as determined by the Compensation Committee in its sole and absolute discretion. The amount of such payment shall be determined by multiplying the excess, if any, of the fair market value of a share of common stock on the date of exercise over the fair market value of the common stock on the grant date, by the number of shares of common stock with respect to which the Stock Appreciation Rights are being exercised.
Restricted Stock
Shares of Restricted Stock may be granted, in such amounts and on such terms and conditions as the Compensation Committee may determine, in its sole and absolute discretion. The Compensation Committee shall impose such restrictions on any Restricted Stock granted under the 2018 Plan as it may deem advisable.
Except as provided by the Compensation Committee in its sole and absolute discretion, Restricted Stock granted under the 2018 Plan will vest over a four-year period after the grant date in equal annual increments. Shares of Restricted Stock may also be granted subject to performance goals, and such shares will be released from restrictions only after the attainment of such performance goals has been certified by the Compensation Committee.
Unless otherwise provided by the Compensation Committee, until the expiration of all applicable restrictions, and subject to the terms of the Plan, (i) the Restricted Stock is treated as outstanding common stock in the Company, (ii) the participant holding shares of Restricted Stock may exercise full voting rights with respect to such shares, and (iii) the participant holding shares of Restricted Stock is entitled to all dividends and other distributions paid with respect to such shares while they are so held.
Restricted Stock Units (RSUs)
RSUs may be granted, in such amounts and on such terms and conditions as the Compensation Committee may determine, in its sole and absolute discretion. The Compensation Committee shall impose such restrictions on any RSUs granted under the 2018 Plan as it may deem advisable.
Unless otherwise provided by the Compensation Committee in an award agreement, upon the expiration of all applicable restrictions, shares of the Company’s common stock will be paid within 60 days following the date the restrictions lapse.

Table of Contents
Participant’s holding RSUs will not have any rights of a stockholder until the underlying shares of the Company’s common stock are delivered.
Performance Shares and Performance Units
Performance Shares and Performance Units may be granted, in such amounts and on such terms and conditions as the Compensation Committee may determine, in its sole and absolute discretion. Performance Shares and Performance Units will be subject to the attainment of one or more
pre-established
performance goals. Such performance goals shall be established by the Committee in writing (other than options and SARs) and shall be based on one or more of the following business criteria: (i) the attainment of certain target levels of, or a specified increase in, the Company’s enterprise value or value creation targets; (ii) the attainment of certain target levels of, or a percentage increase in, the Company’s
after-tax
or
pre-tax
profits including, without limitation, that attributable to the Company’s continuing and/or other operations; (iii) the attainment of certain target levels of, or a specified increase relating to, the Company’s operational cash flow or working capital, or a component thereof; (iv) the attainment of certain target levels of, or a specified decrease relating to, the Company’s operational costs, or a component thereof; (v) the attainment of a certain level of reduction of, or other specified objectives with regard to limiting the level of increase in all or a portion of bank debt or other of the Company’s long-term or short-term public or private debt or other similar financial obligations of the Company, which may be calculated net of cash balances and/or other offsets and adjustments as may be established by the Committee; (vi) the attainment of a specified percentage increase in earnings per share or earnings per share from the Company’s continuing operations; (vii) the attainment of certain target levels of, or a specified percentage increase in, the Company’s net sales, revenues, net income or earnings before income tax or other exclusions; (viii) the attainment of certain target levels of, or a specified increase in, the Company’s return on capital employed or return on invested capital; (ix) the attainment of certain target levels of, or a percentage increase in, the Company’s
after-tax
or
pre-tax
return on stockholder equity; (x) the attainment of certain target levels in the fair market value of the Company’s common stock; (xi) the growth in the value of an investment in the common stock assuming the reinvestment of dividends; (xii) the attainment of certain target levels of, or a specified increase in, EBITDA (earnings before income tax, depreciation and amortization); and/or attainment of synergies and cost reductions in connection with mergers, acquisitions and similar corporate transactions involving the Company. As soon as practicable after the end of a performance period (as set forth by the Compensation Committee), the Compensation Committee shall determine to what extent the Performance Shares or Performance Units have been earned on the basis of the Company’s performance.

other than by will or by the laws of descent and distribution or as otherwise expressly allowed by the Compensation Committee pursuant to a gift to members of an eligible person’s immediate family. The gift may be directly or indirectly transferred, by means of a trust, partnership, or otherwise. Stock options and SARs may be exercised only by the optionee, any such permitted transferee or a guardian, legal representative or beneficiary.
Treatment of Awards upon a Change in Control
If there is a change in control of Catalyst Pharmaceuticals, Inc., any award that is not exercisable and vested may immediately become exercisable and vested in the sole and absolute discretion of the Compensation Committee. Vested awards will be deemed earned and payable in full. The Compensation Committee may also terminate the awards, entitling participants to a cash payment. If we are liquidated or dissolved, awards may also be converted into the right to receive liquidation proceeds. In the event that the Compensation Committee does not terminate or convert an award upon a change of control, then the award will be assumed, or substantially equivalent awards will be substituted, by the acquiring or succeeding corporation.
Amendments, Modifications and Termination
Our Board may, at any time, amend, suspend or terminate the 2018 Plan, but the Board may not impair the rights of holders of outstanding awards without the holder’s consent. No amendment to the 2018 Plan may be made without consent of our stockholders. In the event that an award is granted to a person residing outside of the United States, the Board may, at its discretion, modify the terms of the agreement to comply with the laws of the country of which the eligible individual is a resident. The 2018 Plan will terminate 10 years after its effective date.
Material Federal Income Tax Consequences
The following is a brief description of the principal federal income tax consequences, as of the date of this proxy statement, associated with the grant of awards under the 2018 Plan. This summary is based on our understanding of present United States federal income tax law and regulations. The summary does not purport to be complete or applicable to every specific situation. Furthermore, the following discussion does not address foreign, state or local tax consequences.

Table of Contents
Stock Options
Grant
. There is generally no United States federal income tax consequence to the participant solely by reason of the grant of incentive stock options or nonqualified stock options under the 2018 Plan, assuming the exercise price of the option is not less than the fair market value of the shares on the date of grant.
Exercise
. The exercise of an incentive stock option is not a taxable event for regular federal income tax purposes if certain requirements are satisfied, including the requirement that the participant generally must exercise the incentive stock option no later than three months following the termination of the participant’s employment with us. However, such exercise may give rise to alternative minimum tax liability (see “Alternative Minimum Tax” below). Upon the exercise of a nonqualified stock option, the participant will generally recognize ordinary income in an amount equal to the excess of the fair market value of the shares at the time of exercise over the amount paid by the participant as the exercise price. The ordinary income recognized in connection with the exercise by a participant of a nonqualified stock option will be subject to both wage and employment tax withholding, and we generally will be entitled to a corresponding deduction.
The participant’s tax basis in the shares acquired pursuant to the exercise of an option will be the amount paid upon exercise plus, in the case of a nonqualified stock option, the amount of ordinary income, if any, recognized by the participant upon exercise thereof.
Disqualifying Disposition
. If the participant disposes of shares of our common stock acquired upon the exercise of an incentive stock option (other than in certain tax free transactions) within two years from the date on which the incentive stock option was granted or within one year after the transfer of shares to the participant pursuant to the exercise of the incentive stock option, at the time of disposition the participant will generally recognize ordinary income equal to the lesser of: (i) the excess of each such share’s fair market value on the date of exercise over the exercise price paid by the participant, or (ii) the participant’s actual gain. If the total amount realized on a taxable disposition (including return on capital and capital gain) exceeds the fair market value on the date of exercise of the shares of our common stock purchased by the participant under the option, the participant will recognize a capital gain in the amount of the excess. If the participant incurs a loss on the disposition (the total amount realized is less than the exercise price paid by the participant), the loss will be a capital loss.
Other Disposition
. If a participant disposes of shares of our common stock acquired upon exercise of a nonqualified stock option in a taxable transaction, the participant will recognize capital gain or loss in an amount equal to the difference between the participant’s basis (as discussed above) in the shares sold and the total amount realized upon disposition. Any such capital gain or loss (and any capital gain or loss recognized on a disqualifying disposition of shares of our common stock acquired upon exercise of incentive stock options as discussed above) will be short-term or long-term depending on whether the shares of our common stock were held for more than one year from the date such shares were transferred to the participant.
Alternative Minimum Tax
. Alternative minimum tax is payable if and to the extent the amount thereof exceeds the amount of the taxpayer’s regular tax liability, and any alternative minimum tax paid generally may be credited against future regular tax liability (but not future alternative minimum tax liability). Alternative minimum tax applies to alternative minimum taxable income. Generally, regular taxable income as adjusted for tax preferences and other items is treated differently under the alternative minimum tax.
For alternative minimum tax purposes, the spread upon exercise of an incentive stock option (but not a nonqualified stock option) will be included in alternative minimum taxable income, and the taxpayer will receive a tax basis equal to the fair market value of the shares of our common stock at such time for subsequent alternative minimum tax purposes. However, if the participant disposes of the incentive stock option shares in the year of exercise, the alternative minimum tax income cannot exceed the gain recognized for regular tax purposes, provided that the disposition meets certain third-party requirements for limiting the gain on a disqualifying disposition. If there is a disqualifying disposition in a year other than the year of exercise, the income on the disqualifying disposition is not considered alternative minimum taxable income.
There are no federal income tax consequences to us by reason of the grant of incentive stock options or nonqualified stock options or the exercise of an incentive stock option (other than disqualifying dispositions). At the time the participant recognizes ordinary income from the exercise of a nonqualified stock option, we will be entitled to a federal income tax deduction in the amount of the ordinary income so recognized (as described above), provided that we satisfy our reporting obligations described below. To the extent the participant recognizes ordinary income by reason of a disqualifying disposition of the stock acquired upon exercise of an incentive stock option, and subject to the requirement of reasonableness,
 
20

Table of Contents
the provisions of Section 162(m) of the Code and the satisfaction of a tax reporting obligation, we generally will be entitled to a corresponding deduction in the year in which the disposition occurs. We are required to report to the Internal Revenue Service any ordinary income recognized by any participant by reason of the exercise of a nonqualified stock option. We are required to withhold income and employment taxes (and pay the employer’s share of the employment taxes) with respect to ordinary income recognized by the participant upon exercise of nonqualified stock options.
Stock Appreciation Rights
There are generally no tax consequences to the participant or us by reason of the grant of stock appreciation rights. In general, upon exercise of a stock appreciation rights award, the participant will recognize taxable ordinary income equal to the excess of the stock’s fair market value on the date of exercise over the stock appreciation rights’ base price, or the amount payable. Generally, with respect to employees, we are required to withhold from regular wages or supplemental wage payments an amount based on the ordinary income recognized. Subject to the requirement of reasonableness, the provisions of Section 162(m) of the Code and the satisfaction of a tax reporting obligation, we generally will be entitled to a business expense deduction equal to the taxable ordinary income realized by the participant.
Restricted Stock
Unless a participant makes a Section 83(b) election, as described below, with respect to restricted stock granted under the 2018 Plan, a participant receiving such an award will not recognize U.S. taxable ordinary income and we will not be allowed a deduction at the time such award is granted. While an award remains unvested or otherwise subject to a substantial risk of forfeiture, a participant will recognize compensation income equal to the amount of any dividends received and we will be allowed a deduction in a like amount. When an award vests or otherwise ceases to be subject to a substantial risk of forfeiture, the excess of the fair market value of the award on the date of vesting or the cessation of the substantial risk of forfeiture over the amount paid, if any, by the participant for the award will be ordinary income to the participant and will be claimed as a deduction for federal income tax purposes by us. Upon disposition of the shares received, the gain or loss recognized by the participant will be treated as capital gain or loss, and the capital gain or loss will be short-term or long-term depending upon whether the participant held the shares for more than one year following the vesting or cessation of the substantial risk of forfeiture.
However, by filing a Section 83(b) election with the Internal Revenue Service within 30 days after the date of grant, a participant’s ordinary income and commencement of holding period and the deduction will be determined as of the date of grant. In such a case, the amount of ordinary income recognized by such a participant and deductible by us will be equal to the excess of the fair market value of the award as of the date of grant over the amount paid, if any, by the participant for the award. If such election is made and a participant thereafter forfeits his or her award, no refund or deduction will be allowed for the amount previously included in such participant’s income.
Generally, with respect to employees, we are required to withhold from regular wages or supplemental wage payments an amount based on the ordinary income recognized. Subject to the requirement of reasonableness, the provisions of Section 162(m) of the Code the satisfaction of a tax reporting obligation and any tax withholding condition, we generally will be entitled to a business expense deduction equal to the taxable ordinary income realized by the recipient. Upon disposition of stock, the recipient will recognize a capital gain or loss equal to the difference between the selling price and the sum of the amount paid for such stock, if any, plus any amount recognized as ordinary income upon acquisition (or vesting) of the stock. Such gain or loss will be long- or short-term depending on whether the stock was held for more than one year from the date ordinary income is measured.
Restricted Stock Units (RSUs)
Generally, the recipient of a restricted stock unit award structured to conform to the requirements of Section 409A of the Code or an exception to Section 409A of the Code will recognize ordinary income at the time the shares are delivered to the participant in an amount equal to the excess, if any, of the fair market value of the shares received over any amount paid by the recipient in exchange for the shares. If a restricted stock unit award is subject to Section 409A of the Code, the shares subject to a restricted stock unit award may generally only be delivered upon one of the following events: a fixed calendar date (or dates), separation from service, death, disability, or a change in control. If delivery occurs on another date, unless the restricted stock unit awards otherwise comply with or qualify for an exception to the requirements of Section 409A of the Code, in addition to the tax treatment described above, the recipient will owe an additional 20% federal tax and interest on any taxes owed. The recipient’s basis for the determination of gain or loss upon the subsequent disposition of shares acquired from a restricted stock unit award will be the amount paid, if any, for shares plus any ordinary income recognized when the stock is delivered. Subject to the requirement of reasonableness, the provisions and limitations of Section 162(m) of the Code and the satisfaction of a tax reporting obligation, we will generally be entitled to an income tax deduction equal to the amount of ordinary income realized by the participant.

Section 409A
If an award under the 2018 Plan is subject to Section 409A of the Code, but does not comply with the requirements of Section 409A of the Code, the taxable events as described above could apply earlier than described, and could result in the imposition of additional taxes and penalties. Participants are urged to consult with their tax advisors regarding the applicability of Section 409A of the Code to their awards.
Potential Limitation on Company Deductions
Section 162(m) of the Code generally disallows a tax deduction for compensation in excess of $1 million paid in a taxable year by a publicly held corporation to its chief executive officer and certain other “covered employees”. Our board of directors and Compensation Committee intend to consider the potential impact of Section 162(m) on grants made under the 2018 Plan but reserve the right to approve grants of options and other awards for an executive officer that exceeds the deduction limit of Section 162(m).
Compensation Committee Report
The Compensation Committee has reviewed the “Compensation – Discussion and Analysis” required by Item 402(b) of Regulation
S-K
of the SEC’s rules and regulations with management and based on such review and discussions the Compensation Committee recommended to the Board of Directors that the “Compensation – Discussion and Analysis” be included in this Amendment to the 2025 Annual Report.

CEO Pay Ratio
As required by Item 402(u) of
Regulation S-K, the
Compensation
Committee reviewed a comparison of our CEO’s annual total compensation in fiscal year 2025 to that of all of our other employees for 2025. We identified our median employee by reviewing the base salary, on an annualized basis, for all of our employees as of December 31, 2025, for the period from January 1, 2025 through December 31, 2025, excluding our CEO. After identifying our median employee, we calculated total compensation for such employee using the same methodology we use for our Named Executive Officers as set forth in the 2025 Summary Compensation Table above.
The total annual compensation for fiscal year 2025 for our CEO was $8,177,496, as noted in the “2025 Summary Compensation Table” above. The median of the 2025 annual total compensation of all employees (other than our CEO) was $316,239. The resulting ratio of our CEO’s pay to the pay of our median employee for fiscal year 2025 was 26 to 1.

Table of Contents
SEC rules for identifying the median of the total annual compensation of our employees and calculating the pay ratio based on that employee’s total annual compensation allows companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their employee populations and compensation practices. The pay ratio reported by other companies may not be comparable to the pay ratio for our company, as other companies have headquarters offices in different countries, have different employee populations and compensation practices and may utilize different methodologies, exclusions, estimates and assumptions in calculating their pay ratios. We believe that the pay ratio reported above is a reasonable estimate calculated in a manner consistent with SEC rules based on our internal records and the methodology described above.
We invest in our employees at all levels in our company by rewarding performance that balances risk and reward, empowering professional growth and development and by offering affordable benefits and programs that meet the diverse needs of our employees.

Item 13. Certain Relationships, Related Transactions and Director Independence

Related Person Transaction Parties and Procedures

In November 2017, we adopted our Code of Business Conduct and Ethics, including a conflict-of-interest transaction policy that identifies our procedures for the identification, review, consideration and approval or ratification of conflict of interest transactions. The policy applies where one’s private life or interest interferes, or even appears to interfere, with the interests of our company. Under the policy, a conflict can arise when any of our personnel (or a member of their family) acts or has interests that make it difficult, or makes it appear difficult, to perform their duties for us objectively and effectively. Conflicts can also arise under the policy when our personnel (or a member of their family) receives significant personal benefits as a result of their position in the Company. Any such determination regarding the approval of such a transaction will be made by the Audit Committee or the Board of Directors, with any interested directors abstaining.

Certain Related Party Transactions

Since 2024, we have had no transactions or proposed transactions in which we were or are to be participants and in which any related person had or will have a direct or indirect material interest.

Represents aggregate fees billed for professional services rendered by Grant Thornton LLP for the audit of our financial statements included in our 2025 and 2024 Forms 10-K, for their reviews of our quarterly reports during 2025 and 2024, and for their report on the effectiveness of our internal control over financial reporting as of December 31, 2025 and 2024.

Includes, for 2025 and 2024, $15,209 and $13,539, respectively, for the audit of the financial statements of our wholly owned subsidiary, Catalyst Pharmaceuticals Ireland, Ltd., a corporation organized in the Republic of Ireland.

Pre-Approval of Audit Functions

Pursuant to its written charter, the Audit Committee is responsible for pre-approving all audit and permitted non-audit services to be performed for us by our independent registered public accounting firm or any other auditing or accounting firm. 100% of the services provided to us by Grant Thornton in 2025 and 2024 were pre-approved by the Audit Committee.

AUDIT COMMITTEE REPORT

Management has the primary responsibility for our internal control over financial reporting, the financial reporting process and preparation of our financial statements. Grant Thornton LLP, our independent registered public accounting firm, is responsible for performing an independent audit of our financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB) and to issue a report thereon. Grant Thornton LLP is also responsible for auditing our internal control over financial reporting in accordance with the standards of the PCAOB. The Audit Committee’s responsibility is to select the independent auditors and to monitor and oversee these processes.

The Audit Committee has met and held discussions with management and the independent auditors. Management represented to the Audit Committee that our financial statements were prepared in accordance with accounting principles generally accepted in the United States. The Audit Committee reviewed and discussed the audited financial statements with management and the independent auditors. In fulfilling its responsibilities, the Audit Committee discussed with the independent auditors the matters that are required to be discussed by Auditing Standard No. 1301 (Communication with Audit Committees). In addition, the Audit Committee received from the independent auditors the written disclosures and letter required by PCAOB Ethics and Independence Rule 3526, Communications with Audit Committees Concerning Independence, and the Audit Committee discussed with the independent auditors that firm’s independence. In connection with this discussion, the Audit Committee also considered whether the provision of services by the independent auditors not related to the audit of our financial statements is compatible with maintaining the independent auditor’s independence. During such discussions, the independent auditors confirmed that, as of December 31, 2025, they were independent accountants with respect to our company within the meaning of applicable federal securities laws and the requirements of the PCAOB.

Based upon the Audit Committee’s discussions with management and the independent auditors and the Audit Committee’s review of the representations of management and the reports and letter of the independent auditors provided to the Audit Committee, the Audit Committee recommended to the Board that our audited financial statements for fiscal 2025 be included in our 2025 Form 10-K.

The Audit Committee has also reviewed all non-audit services being provided by the independent auditors and has concluded that the provision of such services has been compatible with the maintenance of that firm’s independence in the conduct of its auditing functions. The Audit Committee has discussed these matters with representatives of the independent auditors and our management and will monitor our compliance with any new restrictions as they are put in place to continue to ensure that the services provided by our independent accountants are compatible with the maintenance of that firm’s independence in the conduct of its auditing functions.
