Item 1.01 Entry into a Material Definitive Agreement.

On October 17, 2024, the Board of Directors (the “Board”) of Kezar Life Sciences, Inc. (“Kezar” or the “Company”), a Delaware corporation, declared a dividend of one right (“Right”) to purchase one-thousandth of one share of the Company’s newly designated Series A Junior Participating Preferred Stock, par value $0.001 per share (each, a “Preferred Share” and collectively, the “Preferred Shares”), for each outstanding share of common stock, par value $0.001 per share, of the Company (“Company Common Stock”) to the stockholders of record as of the close of business on October 28, 2024 (the “Record Date”). The Company also adopted a limited duration stockholder rights plan (the “Rights Plan”), effective immediately, as set forth in the Rights Agreement, dated as of October 17, 2024 (the “Rights Agreement”), by and between the Company and Computershare Trust Company, N.A., as Rights Agent. The Rights Agent currently serves as the Company’s transfer agent with respect to the Company Common Stock and also has been appointed transfer agent with respect to the Preferred Shares, if any, that may be issued pursuant to the exercise of rights under the Rights Agreement. The Rights will expire on October 17, 2025 (“Final Expiration Date”), unless the rights are earlier redeemed or exchanged by the Company. The Company does not have any obligation under the Rights Agreement to seek stockholder approval for the Rights Plan. In general terms, the Rights Plan imposes a significant penalty upon any person or group that acquires beneficial ownership of 10% (15% in the case of a passive institutional investor) or more of the outstanding shares of Company Common Stock without the approval of the Board. The Rights Plan was adopted in response to (i) the unsolicited, non-binding proposal from Concentra Biosciences, LLC (“Concentra”) to acquire all of the outstanding shares of Company Common Stock for cash consideration of $1.10 per share, plus a contingent value right that represents the right to receive 80% of the net proceeds from any out-license or disposition of the Company’s development programs or intellectual property (the “Concentra Proposal”), and (ii) Concentra and its affiliates’ rapid accumulation of 9.9% of the outstanding Company Common Stock. The Rights Plan is intended to enable all stockholders to realize the full value of their investment in the Company and afford the Board adequate time to consider any further proposals from Concentra. The Rights Plan will reduce the likelihood that any entity, person or group gains control of the Company through open market accumulation without paying all stockholders an appropriate control premium or without providing the Board sufficient time to make informed judgments and take actions that are in the best interests of all stockholders. The Rights Plan does not prevent the Board
