(e) Modification of Compensatory Arrangements with Executive Officers

On February 18, 2026, the Compensation Committee (the “Committee”) of Supernus Pharmaceuticals, Inc. (“Supernus” or the “Company”) recommended, and the Board of Directors (the “Board”) approved, modifications of the compensation of the Company’s executive officers, as follows:

The annual base salary of Jack A. Khattar, the Company’s President and Chief Executive Officer, was increased from $1,036,000 to $1,067,100. Mr. Khattar was awarded a 2025 bonus of $846,930 and was granted options to purchase 341,610 shares of common stock and 204,966 performance share units (“PSUs”), which will vest depending upon the level of achievement of specified performance goals. In addition, Mr. Khattar’s bonus target for 2026 is unchanged from 2025 and is 75% of his base salary.

The annual base salary of Timothy C. Dec, the Company’s Senior Vice President and Chief Financial Officer, was increased from $504,900 to $525,100. Mr. Dec was awarded a 2025 bonus of $233,894, and was granted options to purchase 17,500 shares of common stock, 3,000 restricted stock units (“RSUs”), and 3,500 PSUs, which will vest depending upon the level of achievement of specified performance goals. In addition, Mr. Dec’s bonus target for 2026 is unchanged from 2025 and is 45% of his base salary.

The annual base salary of Padmanabh P. Bhatt, Ph.D., the Company’s Senior Vice President, Intellectual Property and Chief Scientific Officer, was increased from $455,900 to $471,900. Dr. Bhatt was awarded a 2025 bonus of $168,182 and was granted options to purchase 13,500 shares of common stock, 3,000 RSUs and 3,500 PSUs, which will vest depending upon the level of achievement of specified performance goals. Dr. Bhatt’s bonus target for 2026 is unchanged from 2025 and is 35% of his base salary.

The annual base salary of Jonathan Rubin, M.D., the Company’s Senior Vice President and Chief Medical Officer, was increased from $485,100 to $504,500. Dr. Rubin was awarded a 2025 bonus of $197,843 and was granted options to purchase 13,500 shares of common stock, 3,000 RSUs and 3,500 PSUs, which will vest depending upon the level of achievement of specified performance goals. Dr. Rubin’s bonus target for 2026 is unchanged from 2025 and is 40% of his base salary.

The annual base salary of Frank Mottola, the Company’s Senior Vice President, Quality, GMP Operations and IT, was increased from $412,500 to $429,000. Mr. Mottola was awarded a 2025 bonus of $173,910 and was granted options to purchase 13,500 shares of common stock, 3,000 RSUs and 3,500 PSUs, which will vest depending upon the level of achievement of specified performance goals. Mr. Mottola’s bonus target for 2026 is unchanged from 2025 and is 40% of his base salary.

These increases were the result of the Committee’s annual compensation review for executive officers. These increases in annual base salary became effective as of January 1, 2026, and are consistent with the Company’s industry peer group and were recommended to the Committee by the Human Capital Solutions practice of Aon plc, its independent compensation consulting company.

The stock option grants and RSU awards are subject to the terms and conditions of the Company’s form of Non-Statutory Time-Based Stock Option Agreement (the “Option Agreement”) and Restricted Stock Unit Award Agreement (the “RSU Agreement”), respectively. Pursuant to such agreements, vesting for all stock option grants and RSUs will occur annually in equal increments over a four year period. The exercise price for the executive officer option grants are $50.20 per share, based on the closing price of February 18, 2026, the date of approval of the grants by the Committee and the Board. All other terms and conditions of the Company’s compensatory arrangements with these executive officers remain unchanged.

The PSU awards are subject to the terms and conditions of the Company’s form of Performance Share Unit Award Agreement (a “PSU Award Agreement”). The PSU Award Agreement provides for the vesting of PSUs based on the level of achievement of the performance goals for the individual executive officer as approved by the Committee or Board. All determinations of whether the performance goals have been achieved and the number of PSUs earned by the executive officer will be made by the Committee in its sole discretion. Upon certification of achievement of the performance goal, the PSUs will vest and become nonforfeitable on the date that the Committee certifies the achievement of the performance goal, subject to the executive officer’s continuous employment from the grant date through the date that the Committee certifies the achievement of the performance goal.

The foregoing description of the terms of the Option Agreement, RSU Agreement and PSU Award Agreement are only summaries, do not purport to be complete, and are qualified in their entirety by reference to the Form of Option Agreement, Form of RSU Agreement and Form of PSU Award Agreement, each of which is incorporated herein. The Form of

Option Agreement, Form of RSU Agreement and Form of PSU Agreement, respectively, were filed with the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024 (incorporated by reference to Exhibits 10.39, 10.41 and 10.49 to the Form 10-K filed on February 25, 2025, File No. 001-35518).
