Item 1.01 Entry into a Material Definitive Agreement.
The information set forth in Item 3.03 of this Current Report is incorporated into this Item 1.01 by reference.
Item 3.03 Material Modification to Rights of Security Holders.
On March 3, 2026, Pliant Therapeutics, Inc. (the “Company”) and Computershare Trust Company, N.A., as rights agent (the “Rights Agent”), entered into an Amendment to Stockholder Rights Agreement (the “Amendment”), amending the Stockholder Rights Agreement, dated as of March 12, 2025, between the Company and the Rights Agent (the “Rights Agreement”).
The Amendment changes the final expiration time of the Rights (as defined in the Rights Agreement) from 5:00 p.m., New York City time on March 11, 2026 to 5:00 p.m., New York City time on March 11, 2027. The Rights may still be earlier redeemed, exchanged or terminated in accordance with the terms of the Rights Agreement.
The extension of the final expiration time under the Rights Agreement is intended to reduce the likelihood that any entity, person or group is able to gain control of the Company through open market accumulation without paying all stockholders an appropriate control premium or providing the Board sufficient opportunity to make informed judgments and take actions that are in the best interests of the Company and all stockholders. The Rights Agreement was not amended in response to any specific takeover offer, and it is not intended to interfere with any merger or other business combination approved by the Board.
This description of the Amendment does not purport to be complete and is qualified in its entirety by reference to the full text of the Amendment, which is filed as Exhibit 4.2 hereto and incorporated herein by reference.
