Item 2.01

Completion of Acquisition or Disposition of Assets.

On January 30, 2026, Standard BioTools Inc., a Delaware corporation (the “Company”) completed the previously announced sale of all of the equity interests of SomaLogic, Inc. (“SomaLogic”), Sengenics Corporation LLC and Sengenics Corporation Pte Ltd (such equity interests, collectively, the “Shares”), the entities that operate the Company’s aptamer-based and functional proteomics business, including KREX, Single SOMAmer and translational and diagnostic assays (the “Business”), pursuant to the terms of the Stock Purchase Agreement (the “Purchase Agreement”), dated as of June 22, 2025, by and between the Company and Illumina, Inc., a Delaware corporation (“Purchaser”) (such transaction, the “Transaction”). The Transaction does not include the Company’s mass cytometry and microfluidics businesses, which are being retained by the Company.

Under the terms of the Purchase Agreement, Purchaser acquired the Shares for aggregate cash consideration of up to $425 million, comprising (i) an upfront payment of $350 million in cash, which was paid at the closing of the Transaction, as adjusted in accordance with the terms of the Purchase Agreement and subject to customary post-closing adjustments as set forth in the Purchase Agreement, and (ii) up to $75 million in earnout payments, payable upon the achievement of specified targets for net revenue generated from SomaScan assay services or any other SOMAmer-based assay services and sales of SOMAmer-based array kits and SOMAmer-based next-generation sequencing library preparation kits in fiscal years 2025 and 2026.

In connection with the completion of the Transaction, as additional consideration, the Company and Purchaser entered into (i) a royalty agreement, pursuant to which the Company will be entitled to a specified royalty stream on net revenues generated from sales of SOMAmer-based next-generation sequencing library preparation kits, (ii) a license agreement, pursuant to which Purchaser will provide a specified license to the Company for the intellectual property relating to Single SOMAmers for potential development and commercialization of Single SOMAmer reagents for use in singleplex affinity assays and (iii) a royalty agreement, pursuant to which the Company will be entitled to a specified royalty stream on net revenues generated from sales of Single SOMAmers.

In connection with the completion of the Transaction, the Company and Purchaser also entered into a transition services agreement, pursuant to which the Company will provide certain services to Purchaser on a transitional basis and for a specified period following the closing of the Transaction in connection with Purchaser’s operation of the Business.

As a result of the closing of the Transaction, which included the sale of all of the equity interests of SomaLogic to Purchaser, the Company no longer has any subsidiary that is a party to the Collaboration Agreement, dated as of December 31, 2021, by and between SomaLogic and Illumina Cambridge, Ltd. (as amended on November 14, 2022, June 15, 2023, September 21, 2023 and June 23, 2025, the “Collaboration Agreement”), and neither the Company nor any of its subsidiaries will be entitled to any royalties or other payments under the Collaboration Agreement.

The Purchase Agreement is not intended to provide any other factual information about the Transaction. The representations, warranties and covenants contained in the Purchase Agreement were made solely for purposes of such agreement and as of specific dates, were solely for the benefit of the parties to the Purchase Agreement, and may be subject to limitations agreed upon by the parties, including being qualified by confidential disclosures made by each party to the other for the purposes of allocating contractual risk between them that differ from those applicable to investors. In addition, certain representations and warranties may be subject to a contractual standard of materiality different from those generally applicable to investors and may have been used for the purpose of allocating risk between the parties rather than establishing matters as facts. Information concerning the subject matter of the representations, warranties and covenants may change after the date of the Purchase Agreement, which subsequent information may or may not be fully reflected in public disclosures by the Company. Investors should not rely on the representations, warranties and covenants or any description thereof as characterizations of the actual state of facts or condition of the Company.

The foregoing description of the Purchase Agreement and the Transaction does not purport to be complete and is qualified in its entirety by reference to the description in the Company’s Current Report on Form 8-K filed with the U.S. Securities and Exchange Commission (the “SEC”) on June 23, 2025 (the “Signing 8-K”), which description is incorporated herein by reference, and the full text of the Purchase Agreement, a copy of which was filed by the Company as Exhibit 2.1 to the Signing 8-K, the full text of which is incorporated herein by reference.
