Shareholder Litigation

On December 12, 2023 two separate stockholder complaints were filed in the District of Delaware. The complaints asserted claims under Section 14(a) of the Exchange Act and Rule 14a-9 promulgated thereunder and Section 20(a) of the Exchange Act for allegedly causing the filing with the SEC on November 14, 2023 of a materially deficient registration statement on Form S-4. Among other remedies, the plaintiffs sought to enjoin a stockholder vote on the proposed Merger. These complaints were voluntarily dismissed. On

December 13, 2023, a complaint was filed in the Court against SomaLogic and certain officers and directors alleging Breach of Fiduciary Duty and Aiding and Abetting Breach of Fiduciary Duty. This complaint also sought an injunction postponing the proposed business combination between SomaLogic and us, which was denied by the Court on January 4, 2024. An amended complaint was filed on June 20, 2024, containing primarily the same allegations, while removing some of the defendants. The remaining defendants filed a motion to dismiss on July 5, 2024, and served an opening brief on August 19, 2024. The Plaintiffs’ opposition brief was filed on December 2, 2024, and the defendants’ reply brief was filed on March 14, 2025. Oral argument was held on the motion to dismiss on July 10, 2025. On August 7, 2025, the Court issued a bench decision denying the defendants’ motion to dismiss. The Company filed its answer and affirmative defenses to the amendment complaint on October 10, 2025. The Court has scheduled a three-day bench trial commencing on March 8, 2027. The parties currently are engaged in discovery. Litigation is inherently uncertain and there can be no assurance regarding the outcome. Whether or not any plaintiffs’ claim is successful, this type of litigation may result in significant costs and divert management’s attention and resources, which could adversely affect the operation of our business.

In March 2024, counsel for SRS, acting as the representative of the securityholders of Palamedrix, sent SomaLogic a letter alleging breaches of the Palamedrix Merger Agreement, dated July 25, 2022, relating to milestone payments. SomaLogic disputed these allegations and issued SRS with a Milestone Abandonment Notice.

On July 2, 2025, SRS filed suit against SomaLogic in the Court, asserting that SomaLogic breached the Palamedrix Merger Agreement – pursuant to which Palamedrix was merged into SomaLogic – by failing to continue investing in the development of certain Palamedrix technology. SRS claims that, had the technology been successfully developed and commercialized, SomaLogic would have been required to pay up to $17.5 million in three sales-based milestone payments.

On August 4, 2025, SomaLogic moved to compel arbitration and/or dismiss the SRS Chancery Action in favor of the dispute resolution procedure for milestone disputes specified in the Palamedrix Merger Agreement. The Court denied the motion, and the matter will continue in the Court. The case will now advance into the discovery phase. Litigation is inherently uncertain, and there can be no assurance regarding the outcome. Whether or not any SRS's claim is successful, this type of litigation may lead to significant costs and divert management's attention and resources, which could adversely affect our business operations.

Additional lawsuits against us and certain of our officers or directors may be filed in the future. If additional similar complaints are filed, absent new or different allegations that are material, we will not necessarily announce such additional filings.

In the normal course of business, the Company is from time to time involved in legal proceedings or potential legal proceedings, including matters involving employment, intellectual property, or others. Although the results of litigation and claims cannot be predicted with certainty, management currently believes that the final outcome of any currently pending matters would not have a material adverse effect on our business, operating results, financial condition, or cash flows. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources, and other factors.
