Item 5.01 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.
On December 15, 2025, Karan Takhar, who serves as Senior Managing Director and head of Life Sciences investing at Matrix Capital Management Company, L.P., resigned from his position as a member of the Board of Directors of Zentalis Pharmaceuticals, Inc. (the “Company”) and from all of the committees on which he served, effective immediately. Mr. Takhar’s resignation was not the result of any disagreement between the Company and him on any matter relating to the Company’s operations, policies or practices.
Effective upon Mr. Takhar’s resignation as a director, the size of the Company’s Board of Directors was reduced from seven to six directors.
Item 8.01 Other Events.
On December 15, 2025 (the “Effective Date”), the Company entered into a Stock Purchase Agreement (the “Agreement”) with Matrix Capital Master Fund, LP (“Matrix”). Pursuant to the Agreement, the Company agreed to repurchase 7,500,000 shares of the Company’s common stock from Matrix at a price of $1.33 per share, representing a discount from the Company’s closing share price of $1.40 on December 12, 2025 (the “Repurchase”). The Repurchase closed on December 15, 2025.
The Repurchase is being effected in connection with the plan by Matrix Capital Management Company L.P., the investment advisor to Matrix, to wind down its family of funds, previously announced in 2024. The Company does not expect the Repurchase to materially impact its projected cash runway into late 2027.

All statements contained in this Form 8-K that do not relate to matters of historical fact should be considered forward-looking statements, including without limitation, statements regarding the impact of the Repurchase on the Company’s expected cash runway into late 2027. These statements are neither promises nor guarantees, but involve known and unknown risks, uncertainties and other important factors that may cause the Company’s actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements, including, but not limited to, the important factors discussed in the sections entitled “Risk Factors” in our most recently filed periodic report on Form 10-K or 10-Q and subsequent filings with the U.S. Securities and Exchange Commission (SEC) and our other filings with the SEC. The forward-looking statements in this Form 8-K are based upon information available to the Company as of the date of this Form 8-K, and while the Company believes such information forms a reasonable basis for such statements, such information may be limited or incomplete, and the statements should not be read to indicate that the Company has conducted an exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain and investors are cautioned not to unduly rely upon these statements. While the Company may elect to update such forward-looking statements at some point in the future, it disclaims any obligation to do so, even if subsequent events cause its views to change.
