Commitments and Contingencies Disclosure [Abstract] |
Commitments and Contingencies | Note 9 — Commitments and Contingencies Legal Matters From time to time, the Company is a party to legal proceedings in the course of the Company's business. The outcome of such matters is inherently uncertain and often involves significant judgment in assessing risk and estimating potential exposure. Accruals are recognized for legal matters when a loss is both probable and reasonably estimable. As of March 31, 2026, no material contingent liabilities have been recognized. If a material loss is reasonably possible and we can estimate the amount or range of the loss, we disclose such information. Unless otherwise noted, either the outcome of these matters is not expected to be material, or the potential loss cannot be reasonably estimated. In re Cytokinetics, Incorporated Securities Litigation On September 17, 2025, a putative stockholder class action lawsuit was filed against the Company and its Chief Executive Officer in the United States District Court for the Northern District of California, alleging violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934. The action was purportedly filed on behalf of a class consisting of all investors who purchased or otherwise acquired the Company's common stock between December 27, 2023 and May 6, 2025. The complaint alleges that the Company made materially false and misleading statements regarding the timeline for the NDA regulatory approval process for aficamten and failed to disclose related material risks. The complaint seeks unspecified damages, together with interest, attorneys' fees, and costs. On December 22, 2025, the Court appointed Gilbert Rosenthal as Lead Plaintiff and approved his selection of Pomerantz LLP as Lead Counsel. The action is now captioned In re Cytokinetics, Incorporated Securities Litigation, Case No. 3:25-cv-07923-RFL. On March 10, 2026, Lead Plaintiff filed an amended complaint, which, among other things, added the Company's Chief Financial Officer as a defendant. The Company expects to file a motion to dismiss the amended complaint within 60 days of its filing. The Company and the individual defendants dispute the allegations in the amended complaint and intend to vigorously defend against the action. Pohlmann v. Blum, et al. On March 9, 2026, a purported stockholder derivative action captioned Pohlmann v. Blum, et al., Case No. 3:26-cv-01998-RFL, was filed in the United States District Court for the Northern District of California against certain of the Company's current and former directors and its Chief Executive Officer, with the Company named as a nominal defendant. The complaint asserts claims for breach of fiduciary duty, aiding and abetting breach of fiduciary duty, unjust enrichment, waste of corporate assets, contribution under the Securities Exchange Act of 1934, and violations of Section 14(a) of the Securities Exchange Act of 1934 and Rule 14a-9 promulgated thereunder. The allegations are based substantially on the same underlying facts and circumstances as those alleged in In re Cytokinetics, Incorporated Securities Litigation and principally concern statements regarding the Company's New Drug Application for aficamten and the subsequent extension of the related PDUFA action date. The complaint seeks, among other relief, unspecified damages on behalf of the Company, disgorgement, corporate governance reforms, and attorneys' fees and costs. On March 27, 2026, the Court found the derivative action to be related to In re Cytokinetics, Incorporated Securities Litigation and reassigned the matter accordingly. On April 16, 2026, the Court entered an order, pursuant to the parties' stipulation, staying the derivative action in its entirety during the pendency of any motion to dismiss in the securities class action, subject to customary terms. The Company and the individual defendants dispute the allegations in the derivative action and intend to vigorously defend against the matter. Other Commitment We have approximately $17.2 million of non-cancellable commitments related to purchases of materials and inventory manufacturing agreements.
