1. Basis of Presentation and Summary of Significant Accounting Policies

Description of the Business

Standard BioTools Inc. (“Standard BioTools” or the “Company”) is a Delaware corporation headquartered in Boston, Massachusetts.

The Company develops, manufactures and sells a diversified range of instrumentation, consumables, and services that help scientists and biomedical researchers develop better therapeutics faster. Its proprietary multi-omics tools provide unique insights into human health, immune response, and disease states across a broad range of applications, including proteomics and genomics, and other areas of translational and clinical research.

The Company works with leading academic, government, pharmaceutical, biotechnology, plant and animal research, and clinical laboratories worldwide, focusing on the most pressing needs in translational and clinical research, including oncology, immunology, and immunotherapy.

Basis of Presentation

The unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and applicable rules and regulations of the U.S. Securities and Exchange Commission (the "SEC") regarding financial reporting. All intercompany transactions and balances have been eliminated in consolidation. These interim condensed consolidated financial statements and related disclosures are unaudited and have been prepared on the same basis as the annual financial statements. In the opinion of management, the accompanying financial statements contain all adjustments of a normal and recurring nature, necessary for a fair statement of the Company's financial position as of March 31, 2026, results of operations for the three months ended March 31, 2026 and 2025, and cash flows for the three months ended March 31, 2026 and 2025. The condensed consolidated balance sheet at December 31, 2025 was derived from the Company's audited annual financial statements included in the Annual Report but does not contain all of the footnote disclosures from the annual financial statements. Certain prior period amounts have been reclassified to conform to the current period presentation.

Certain information and disclosures normally included in consolidated financial statements prepared in accordance with GAAP have been condensed or omitted. Accordingly, these condensed consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements as of and for the year ended December 31, 2025 (the "2025 Financial Statements") included in the Company's Annual Report.

On June 22, 2025, the Company entered into a Stock Purchase Agreement (the "Purchase Agreement") with Illumina. Pursuant to the terms of the Purchase Agreement, Illumina acquired all of the equity interests of SomaLogic, Inc. ("SomaLogic"), Sengenics Corporation LLC and Sengenics Corporation Pte Ltd (collectively, the "Disposed Entities"), each a wholly owned subsidiary of the Company that operates the Company's aptamer-based and functional proteomics business, including KREX, Single SOMAmer, translational and diagnostic assays (collectively, the "SomaScan Business") (such transaction, the "Transaction"). The Transaction does not include the Company's mass cytometry and microfluidics businesses, which were retained by the Company. The Transaction closed on January 30, 2026. See Note 2, Discontinued Operations, for additional information.

Consistent with Accounting Standards Codification ("ASC") 205, Presentation of Financial Statements, the Company classifies disposal groups as held-for-sale in the reporting period when all the held-for-sale classification criteria are met. Disposal groups held for sale are presented as discontinued operations when the disposal represents a strategic shift with a major effect on operations, and the operations and cash flows are clearly distinguishable from the rest of the entity. Upon classification as held-for-sale, assets and liabilities are presented as held-for-sale and measured at the lower of carrying value or fair value less costs to sell, and upon classification as discontinued operations, results of operations are reclassified as discontinued operations for all periods presented.

The Company determined that the SomaScan Business met the held-for-sale and discontinued operations accounting criteria in the second quarter of 2025. The Company completed the sale of the SomaScan Business on January 30, 2026. Accordingly, the Company has classified the results of the SomaScan Business as discontinued operations in its condensed consolidated statements of operations for all periods presented. The assets and liabilities of the SomaScan Business were classified as held-for-sale in the condensed consolidated balance sheet as of December 31, 2025. Upon closing of the Transaction on January 30, 2026, the Company derecognized all assets and liabilities of the SomaScan Business and recognized a pre-tax gain on sale of $172.3 million, which is reflectedin income from discontinued operations, net of tax, in the condensed consolidated statements of operations for the three months ended March 31, 2026. The cash flows related to discontinued operations have not been segregated and are included in the condensed consolidated statements of cash flows. The discussions in these notes to the condensed consolidated financial statements relate solely to the Company's continuing operations, unless otherwise noted. For further discussion of the discontinued operations related to the SomaScan Business, refer to Note 2, Discontinued Operations.

Interim results are not necessarily indicative of the results to be expected for the full year ending December 31, 2026.

Segment Reporting

The Company identifies operating and reportable segments based on how the chief operating decision maker (“CODM”) manages the business, allocates resources, makes operating decisions and evaluates operating performance. The Company's Chief Executive Officer (“CEO”) is its CODM. The Company reassesses its operating segments when facts and circumstances suggest that there may have been a change in the way that the Company is managed.

The CODM manages the business on a consolidated basis, as a multi-omics company. Therefore, the Company concluded it hasone operating and reportable segment: the consolidated company.

The segment information presented reflects the Company's continuing operations and excludes discontinued operations. See Note 11, Segment Reporting, for more information on the reportable segment.

Contingent Consideration Receivable

Contingent consideration arrangements arising from the disposal of a business are evaluated to determine whether the arrangement meets the definition of a derivative in accordance with ASC 815. When the arrangement qualifies for a scope exception under ASC 815 or does not meet the definition of a derivative, the Company has elected to recognize contingent consideration when it is determined to be realizable in accordance with ASC 450. Any gains or losses from the subsequent accounting for contingent consideration are recognized within the same financial statement line item as the original gain or loss on the sale.

Use of Estimates

The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and disclosed in the accompanying notes. Actual results could differ materially from these estimates.

Significant estimates and assumptions which form the basis of amounts reported in the condensed consolidated financial statements include, but are not limited to, the identification of performance obligations in contracts with customers; standalone selling prices of the Company's performance obligations; timing of revenue recognition; fair value measurements; net realizable value of inventory; income taxes; and impairment of long-lived assets (property and equipment, and operating lease right-of-use assets). The Company bases its estimates on current facts and circumstances, historical experience, forecasted results, and various other assumptions that it believes to be reasonable. The Company obtains reports from third-party valuation experts to inform and support estimates related to certain fair value measurements.

Recent Accounting Changes and Accounting Pronouncements

Adoption of New Accounting Guidance

In July 2025, FASB issued Accounting Standards Update No.2025-05, Financial Instruments - Credit Losses: Measurement of Credit Losses for Accounts Receivable and Contract Assets (“ASU 2025-05”), which provides a practical expedient for estimating expected credit losses for current accounts receivable and current contract assets. ASU 2025-05 will be effective for annual periods beginning after December 15, 2025 and interim periods within those annual reporting periods and should be applied prospectively. The Company adopted this ASU on January 1, 2026 and elected to utilize the practical expedient. The adoption of the ASU and the election of the practical expedient didnot have a material impact on our Condensed Consolidated Financial Statements.

Recent Accounting Pronouncements

In November 2024, the FASB issued ASU No. 2024-03, Disaggregation of Income Statement Expenses. The new standard requires additional disclosure of the nature of the expenses included in the income statement, including disaggregation of the expense captions presented on the face of the income statement into specific categories. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, with early adoption permitted, and may be applied retrospectively or prospectively. The Company is currently evaluating the impact of this standard on its consolidated financial statements and disclosures.

In September 2025, the FASB issued ASU 2025-06, Targeted Improvements to the Accounting for Internal-Use Software. The new standard modernizes the recognition and disclosure framework for capitalized internal-use software costs, removing the previous "development" stage model and introducing a judgment-based approach. ASU 2025-06 is effective for fiscal years beginning after December 15, 2027, with early adoption permitted, and may be applied using a prospective, retrospective, or modified transition approach. The Company is currently evaluating the impact of this standard on its consolidated financial statements and disclosures.

In December 2025, the FASB issued ASU 2025-10, Accounting for Government Grants Received by Business Entities. The new standard provides guidance on the recognition, measurement, and presentation of government grants. ASU 2025-10 is effective for fiscal years beginning after December 15, 2028, with early adoption permitted, and may be applied using a modified prospective, modified retrospective or full retrospective transition approach. The Company is currently evaluating the impact of this standard on its consolidated financial statements and disclosures.

2. Discontinued Operations

On June 22, 2025, the Company entered into the Purchase Agreement with Illumina for the divestiture of the SomaScan Business. On January 30, 2026, the Company completed the sale of the Disposed Entities to Illumina pursuant to the Purchase Agreement. The Disposed Entities comprised the Company's SomaScan Business, including its SomaScan assay platform and related products and services. The Company retained its mass cytometry and microfluidics businesses, which were not part of the Transaction.

At closing, the Company received net cash consideration of $363.2 million and recognized $25.0 million of consideration receivable based on the achievement of specified revenue thresholds during fiscal year 2025, for total net consideration of $388.2 million. The total consideration is subject to customary post-closing adjustments for working capital. In addition, the Company is eligible to receive additional contingent earnout payments of up to $50.0 million based on the achievement of specified revenue thresholds for SomaScan assay services and related products during fiscal year 2026. The Company will recognize the contingent earnout consideration as it becomes realizable.

The Company recognized a pre-tax gain of $172.3 million on the sale, calculated as the excess of the fair value of consideration received and consideration receivable over the carrying value of the net assets of the Disposed Entities, including allocated goodwill. As a result of this gain, the Company recognized $39.2 million of income tax expense. The gain and income tax expense are reflected in income from discontinued operations, net of tax.

In connection with the closing, the Company and Illumina entered into (i) a royalty agreement, pursuant to which the Company is 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 Illumina provided 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 single plex affinity assays, and (iii) a royalty agreement, pursuant to which the Company is entitled to a specified royalty stream on net revenues generated from sales of Single SOMAmers. The royalty rates are low- to mid-single digit percentages. The royalty arrangements described in (i) and (iii) are considered to be contingent consideration for the sale of the SomaScan Business. The Company has elected to account for this contingent consideration as a gain contingency under ASC 450-30 and will recognize royalty income when it is realized or becomes realizable.

As a result of the closing of the Transaction, the Company no longer has any subsidiary that is a party to the collaboration agreement that the Company previously entered into with Illumina in December 2021 (the “Collaboration Agreement”), and neither the Company nor any of its subsidiaries is entitled to any royalties or other payments under the Collaboration Agreement.

The results of operations of the Disposed Entities are reported as discontinued operations for all periods presented. The following tables summarize the financial results of the discontinued operations:

(1)

During the three months ended March 31, 2026, the Company recognized revenue of $29.8 million related to the transaction price under the Collaboration Agreement with Illumina, which primarily reflects the release of the deferred revenue balance previously established under the Collaboration Agreement upon the sale of the SomaScan Business. The Company has classified the $29.8 million within discontinued operations consistent with the treatment of all SomaScan Business-related activities. Out of the $29.8 million recognized, $0.6 million reflects Illumina’s exercise of its material right to be provided with SOMAmer reagents for commercialization of the co-branded kits.

Details of non-cash operating expenses and capital expenditures of the discontinued operations are as follows:

Legal Proceedings

Stockholder Litigation

In December 2023, prior to the Company's merger with SomaLogic, a complaint was filed in the Delaware Court of Chancery against SomaLogic and certain of its officers and directors alleging breach of fiduciary duty in connection with the proposed merger. The Company assumed this litigation upon closing of the merger in January 2024 and retained it following the sale of the SomaScan Business to Illumina in January 2026. A three-day bench trial is scheduled to commence on March 8, 2027, and discovery is ongoing. The Company has not recorded any contingent liabilities related to this matter. The Company does not believe the ultimate resolution will have a material adverse effect on its financial condition, results of operations, or cash flows.

Palamedrix Litigation

On July 2, 2025, Shareholder Representative Services LLC ("SRS"), acting as the representative of the securityholders of Palamedrix, Inc. ("Palamedrix"), filed suit in the Delaware Court of Chancery against SomaLogic asserting that SomaLogic breached the Agreement and Plan of Merger, dated July 25, 2022, by failing to continue investing in the development of certain Palamedrix technology. SRS claims that SomaLogic would have been required to pay up to $17.5 million in sales-based milestone payments. SomaLogic's motion to compel arbitration was denied, and the matter is proceeding into discovery. The Company is obligated to indemnify Illumina for losses arising from this matter. As of March 31, 2026, the Company has accrued $3.3 million related to this indemnification obligation.

General

The Company is from time to time involved in legal proceedings in the normal course of business. Although the outcomes of litigation 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 the Company's business, operating results, financial condition, or cash flows.

7. Stockholders’ Equity (Deficit)

2024 Stock Repurchase Program

On February 6, 2024, the Board of Directors authorized the repurchase of up to $50.0 million of shares of the Company’s common stock through March 1, 2026. The program expired on March 1, 2026, and no shares were repurchased during the three months ended March 31, 2026. Over the life of the program, the Company repurchased 15,448,533 shares for an aggregate of $40.5 million.

Common Shares Reserved

As of March 31, 2026, the Company had reserved shares of common stock for future issuance under equity compensation plans as follows (in thousands):

8. Stock-based Compensation

The Company has various stock-based compensation plans, which are more fully described in the Annual Report. Under these plans, the Company has the ability to grant several forms of incentive awards to the Company's eligible employees, directors, and non-employee consultants.

Stock-based compensation expense is reported in the Company's condensed consolidated statements of operations as follows (in thousands):

Stock-based compensation will fluctuate based on the grant-date fair value of awards, the number of awards, the requisite service period of the awards, employee forfeitures and the timing of the awards. Expense related to each stock option and restricted stock unit (“RSU”) award is recognized on a straight-line basis over the requisite service period of the entire award.

The following table summarizes our award activity for stock options and RSUs for the three months ended March 31, 2026 (in thousands):

9. Net Loss Per Share

The following potentially dilutive common shares were excluded from the computations of diluted net loss per share for the periods presented because including them would have been anti-dilutive (in thousands):

10. Income Taxes

The Company’s quarterly provision for income taxes is based on an estimated annual effective income tax rate. The quarterly provision for income taxes also includes discrete items, such as changes in valuation allowances or adjustments upon finalization of tax returns as well as infrequently occurring items, if any, such as the effects of changes in tax laws or rates, in the interim period in which they occur.

The Company recorded income tax expense of $11 thousand and income tax benefit of $0.1 million in thethree months ended March 31, 2026 and 2025, respectively. The increase in the Company's tax expense reflects higher minimum tax expense for the various States that the Company operates in, as well as the effect of the Company's foreign operations, which reported higher pre-tax income in the first three months of 2026 compared to the same period in 2025.

The Company’s effective tax rates for both periods differ from the 21% U.S. federal statutory tax rate primarily due to valuation allowances recorded against deferred tax assets on domestic losses and the tax rate differences between the United States and foreign countries. The Company maintains a valuation allowance against its U.S. deferred tax assets as the Company believes it is more likely than not the deferred tax assets will not be realized.

11. Segment Reporting

As of March 31, 2026, the Company hasone operating and reportable segment. The CODM utilizes the Company's annual operating plan, primarily consisting of an annual financial forecast, as a key input to resource allocation. The CODM makes decisions on resource allocation and assesses performance of the business using net income/loss from continuing operations.

The significant expenses within net loss that are regularly provided to the CODM include cost of revenue and operating expenses. Operating expenses consist of four main subcategories: research and development; selling, general and administrative; transaction and integration; and restructuring and related. All significant expense categories and subcategories are reported on the condensed consolidated statements of operations. Other segment items within net loss include the following:

•

Depreciation and amortization expense, which is separately presented on the condensed consolidated statements of cash flows

•

Change in fair value of contingent consideration, which is separately presented on the condensed consolidated statements of cash flows

•

Interest income and interest expense, which are separately presented on the condensed consolidated statements of operations

13. Related Parties

In December 2025, the Company invested $5.0 million in unsecured convertible loan notes issued by a privately-held life sciences company. The notes bear interest at 8% per annum, mature in December 2027, and are subordinated to the issuer's senior indebtedness. The notes automatically convert into equity upon a qualified financing of at least $20 million or an initial public offering with gross proceeds of at least $100 million, in each case at a 20% discount to the applicable offering price. At maturity, any outstanding principal and accrued interest automatically convert into preferred shares at a conversion price based on a valuation cap of eight times the issuer's trailing 12-month revenue. The Company invested in the notes alongside a fund associated with Eli Casdin, a member of the Company’s board of directors and the Company’s principal stockholder.
