Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.
Effective May 22, 2026, the Board of Directors (the “Board”) of Zentalis Pharmaceuticals, Inc. (the “Company”) increased its size from six to seven directors and appointed Shannon Campbell, as a Class I director. Ms. Campbell's initial term is scheduled to expire at the Company's 2027 Annual Meeting of Stockholders, subject to the election and qualification of her successor and her earlier death, resignation or removal. Ms. Campbell has also been appointed to serve on the Compensation Committee of the Board (the “Compensation Committee”).
There is no arrangement or understanding between Ms. Campbell and any other person pursuant to which she was appointed as a director of the Company, and there are no family relationships between Ms. Campbell and any of the Company’s directors or executive officers. There are no transactions to which the Company is a party and in which Ms. Campbell has a direct or indirect material interest that would be required to be disclosed under Item 404(a) of Regulation S-K.
Ms. Campbell is entitled to receive compensation for her service as a director in accordance with the Company's Non-Employee Director Compensation Program applicable to all non-employee directors (the “Director Compensation Program”), which provides for an annual retainer of $45,000 for her Board service, and additional annual retainer of $7,500 for her service as a member of the Compensation Committee.
In accordance with the Director Compensation Program, as a new non-employee director, Ms. Campbell was granted restricted stock units (“RSUs”) covering 114,200 shares of the Company's common stock on May 26, 2026, which number of shares was determined by multiplying (i) the number of common shares outstanding as of the day prior to the date of grant, by (ii) 0.16% (such percentage determined by the board). The initial RSU grant vests over three years with one-third of the underlying shares vesting on each of the first, second and third anniversaries of the date of grant.
Also in accordance with the Director Compensation Program, after Ms. Campbell has served on the Board for at least six months, Ms. Campbell is entitled to receive an annual equity grant on the date of the Company's next annual meeting of stockholders of RSUs covering that number of shares of the Company's common stock as is determined by multiplying (i) the number of common shares outstanding as of the day prior to the date of grant, by (ii) 0.08%. Annual RSU awards granted to non-employee directors vest in full on the first to occur of (i) the first anniversary of the applicable grant date, and (ii) the next occurring annual meeting of the Company's stockholders.
Pursuant to the Director Compensation Program, the initial and annual equity awards granted to Ms. Campbell under the Director Compensation Program vest in full upon a change in control and, in each case, are subject to Ms. Campbell's continued service through the applicable vesting date.
Ms. Campbell has also entered into the Company's standard indemnification agreement for directors and officers, the form of which is included as Exhibit 10.6 to the Company's Annual Report on Form 10-K filed on March 26, 2026.
