STANDARD BIOTOOLS INC.

NOTES TO CONDENSED C ONSOLIDATED FINANCIAL STATEMENTS

June 30, 2026

1. B asis 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 June 30, 2026, results of operations for the three and six months ended June 30, 2026 and 2025, and cash flows for the six months ended June 30, 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 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 operated 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 3, 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

6

reflected in income from discontinued operations, net of tax, in the condensed consolidated statements of operations for the six months ended June 30, 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 3, 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 has one operating and reportable segment: the consolidated company.

The segment information presented reflects the Company's continuing operations and excludes discontinued operations. See Note 12, 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 did no t have a material impact on our condensed consolidated financial statements.

Recent Accounting Pronouncements

7

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. Merger Agreement

On June 6, 2026, the Company entered into an Agreement and Plan of Merger and Reorganization (the "Merger Agreement") with Treeline Biosciences, Inc. ("Treeline") and Siri Merger Sub, Inc., a wholly owned subsidiary of the Company ("Merger Sub"), pursuant to which the Company and Treeline will combine in an all-stock merger. Pursuant to the Merger Agreement, Merger Sub will merge with and into Treeline, with Treeline surviving as a wholly owned subsidiary of the Company (the "Merger"). At the effective time of the Merger, the Company will be renamed Treeline Biosciences Holdings, Inc. and will effect a reverse stock split of its outstanding common stock, if not effected prior to the effective time as permitted by the Merger Agreement.

At the effective time of the Merger, each outstanding share of Treeline capital stock will be converted into the right to receive shares of the Company's common stock based on an exchange ratio calculated in accordance with the Merger Agreement. Following the closing, the Company's existing stockholders are expected to hold approximately 16% of the combined company on a fully diluted basis, and former Treeline stockholders are expected to hold approximately 84%, subject to adjustment in accordance with the Merger Agreement. In accordance with the Merger Agreement, the board of directors of the combined company following the Merger is expected to consist of 10 directors nominated by Treeline and two directors nominated by the Company, and Treeline’s management team will become the management team of the combined company.

The Merger is expected to be accounted for as a reverse recapitalization, with Treeline treated as the accounting acquirer. This determination is preliminary and subject to the final terms of the Merger and the completion of the disposition of the Company's mass cytometry and microfluidics businesses.

Prior to the effective time of the Merger, the Company expects to declare a dividend to its stockholders of one contingent value right ("CVR") for each outstanding share of the Company's common stock. Each CVR will entitle the holder to receive, for each 12-month payment period during the five-year term of the CVR agreement, a pro rata portion of the net proceeds received by the combined company from specified sources, less certain permitted deductions, including proceeds from the sale, disposition, or other monetization of the Company's mass cytometry and microfluidics businesses; proceeds from convertible notes or other investments held by the Company as of the closing date; contingent payments due to the Company under contracts in effect as of the closing date; and certain other amounts specified in the CVR agreement. Payments in respect of the CVR will be settled in shares of the combined company's common stock, subject to a maximum of 76.0 million shares issuable under the CVR agreement. There can be no assurance that any payments will be made on the CVR.

Under the Merger Agreement, the Company must use commercially reasonable efforts to effect the sale, license, transfer, disposition, divestiture or other monetization of its mass cytometry and microfluidics businesses. If the Company has not entered into a definitive agreement for the disposition of any portion of these businesses on or before the date the registration statement on Form S-4 filed in connection with the Merger is declared effective, the Company is required to commence mutually agreed wind-down activities with respect to that portion of the business. On July 28, 2026, the Company entered into a Share and Asset Purchase Agreement with Multiplex Bio Inc. under which, subject to the terms and conditions set forth therein, Multiplex Bio will acquire the mass cytometry business of the Company.

Completion of the Merger is subject to customary closing conditions, including approval by the Company's stockholders of the share

8

issuance and an amendment to the Company's certificate of incorporation, effectiveness of the registration statement on Form S-4, continued listing of the Company's common stock on Nasdaq and approval for listing of the shares issuable in the Merger, and expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act (such waiting period was terminated early on July 21, 2026). The Merger is expected to close in the second half of 2026. If the Merger is not consummated by March 31, 2027, either party may terminate the Merger Agreement. Upon termination under specified circumstances, the Company may be required to pay Treeline a termination fee of $16.1 million or to reimburse Treeline's transaction expenses up to $5.0 million (with any such expense reimbursement credited against any such termination fee).

3. 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 $388.2 million, which included $25.0 million of contingent consideration received based on the achievement of specified revenue thresholds during fiscal year 2025. 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 recognizes contingent earnout consideration when it becomes realizable, and accordingly no amount was recorded as of June 30, 2026. In July 2026, the Company agreed to settle the remaining contingent earnout for $30.0 million in cash. See Note 15, Subsequent Events.

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 was entitled to a specified royalty stream on net revenues generated from sales of Single SOMAmers. The royalty rates were low- to mid-single digit percentages. The royalty arrangements described in (i) and (iii) were considered to be contingent consideration for the sale of the SomaScan Business. The Company elected to account for this contingent consideration as a gain contingency under ASC 450-30. These agreements were terminated in July 2026. See Note 15, Subsequent Events.

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:

During the six months ended June 30, 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.

6. Commit ments and Contingencies

Other Commitments

The Company has entered into several license and patent agreements under which it pays annual license maintenance fees, non-refundable license issuance fees, and royalties as a percentage of net sales for the sale or sublicense of products using the licensed technology. Future payments related to these license agreements are indeterminable. The Company does not expect the license payments to be material in any particular year.

Indemnification

In the ordinary course of business, the Company has entered into agreements with certain business partners, customers, and suppliers that contain indemnification provisions. Pursuant to these agreements, the Company may indemnify, hold harmless, and reimburse the indemnified parties for losses suffered in connection with any patent or other intellectual property infringement claim by any third party with respect to the Company's products. The term of the indemnification provisions is generally perpetual, and the maximum potential amount of future payments is typically not limited to a specific amount.

The Company has also entered into indemnification agreements with its officers, directors, and certain other employees, providing for indemnification for related expenses including attorneys' fees, judgments, fines, and settlement amounts incurred in any action or proceeding arising by reason of their status or service.

Legal Proceedings

SomaLogic Stockholder Litigation

In December 2023, a complaint was filed in the Delaware Court of Chancery against the Company, Casdin Capital, LLC, SomaLogic, and the directors of SomaLogic alleging Breach of Fiduciary Duty and Aiding and Abetting Breach of Fiduciary Duty. This complaint also sought an injunction postponing the business combination between SomaLogic and the Company, which was denied by the Court in January 2024. An amended complaint was filed in June 2024, containing primarily the same allegations, while removing the Company, SomaLogic and some of the SomaLogic director defendants as parties to the litigation. The remaining defendants filed motions to dismiss in July 2024. In August 2025, the Court issued a bench decision denying the defendants’ motions to dismiss. The defendants filed answers and affirmative defenses to the amended complaint in October 2025. The Court scheduled a three-day bench trial commencing in March 2027.

The Company is no longer a party to this litigation, and the Company does not expect this matter to have a material effect on its financial statements.

Palamedrix Litigation

In March 2024, counsel for Shareholder Representative Services LLC (“SRS”), acting as the representative of the securityholders of Palamedrix, Inc. (“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. In July 2025, SRS filed suit against SomaLogic in the Court (the “SRS Chancery Action”), 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. In August 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 continued in the Court.

In July 2026, the parties reached an agreement fully resolving the matter. See Note 15, Subsequent Events.

General

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.

13

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.

11. 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 $0.1 million and an income tax benefit of $0.6 million in the three months ended June 30, 2026 and 2025, respectively. The Company recorded income tax expense of $0.1 million and an income tax benefit of $0.7 million during the six months ended June 30, 2026 and 2025, respectively. The increase in the Company's tax expense reflects higher

16

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 six 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.

12. Segment Reporting

As of June 30, 2026, the Company has one 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, net, which are separately presented on the condensed consolidated statements of operations

See Note 4, Revenue and Geographic Area, for the Company's revenue by geography.

Convertible Loan Notes

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 Founder and Chief Investment Officer of Casdin Capital, LLC, a major stockholder of the Company.

Merger Agreement with Treeline

As described in Note 2, on June 6, 2026, the Company entered into the Merger Agreement with Treeline. Entities affiliated with Casdin Capital, LLC beneficially own approximately 23% of the Company's outstanding common stock, and Eli Casdin, the Founder and Chief Investment Officer of Casdin Capital, is a member of the Company's board of directors. Entities affiliated with Casdin Capital are also equity investors in Treeline, owning approximately 5% of Treeline's outstanding capital stock, and would receive shares of the Company's common stock in the Merger in exchange for their Treeline capital stock on the same terms as other Treeline stockholders.

15. Subsequent Events

Indemnification Payment

On July 21, 2026, the Company made a payment to Illumina in satisfaction of the indemnification obligation related to the Palamedrix matter that was accrued as of June 30, 2026, which is now settled. See Note 6, Commitments and Contingencies.

Termination of Earnout and Royalty and License Agreements

On July 24, 2026, the Company entered into a Termination, Waiver and Release Agreement with Illumina, pursuant to which the Company received a payment of approximately $30.0 million in cash from Illumina in exchange for waiving its right to the 2026 earnout under the Stock Purchase Agreement dated June 22, 2025, and terminating the related royalty and license agreements entered into at the closing of the sale of the SomaScan Business. See Note 3, Discontinued Operations. The Company expects to recognize a gain of approximately $30.0 million during the third quarter of 2026.

Sale of Mass Cytometry Business

On July 28, 2026, the Company entered into a Share and Asset Purchase Agreement with Multiplex Bio Inc. ("Multiplex Bio"), pursuant to which Multiplex Bio will acquire the Company's mass cytometry business. Total consideration is up to $10.0 million, consisting of $5.0 million payable at closing through the issuance of a promissory note bearing interest at 6% per annum and maturing on the fifth anniversary of the closing, and up to an additional $5.0 million payable if Multiplex Bio consummates a qualifying sale transaction above a specified threshold within ten years of the closing. The Company will not receive cash consideration at closing. If Multiplex Bio is unable to obtain a working capital loan facility prior to closing, the Company is required to provide Multiplex Bio a working capital loan at closing of up to $10.0 million.

Consummation of the transaction is subject to customary closing conditions, including approval by the Company's stockholders and consummation of the Merger described in Note 2, Merger Agreement. The transaction did not meet the criteria to be classified as held for sale as of June 30, 2026. The Company may recognize a loss on the sale upon closing; an estimate of such loss, if any, cannot currently be made, as it will depend on the carrying value of the net assets transferred at closing, the fair value of the consideration received, and transaction costs.

Recent Developments

Merger Agreement

On June 6, 2026, we entered into an Agreement and Plan of Merger and Reorganization (the "Merger Agreement") with Treeline Biosciences, Inc. ("Treeline") and Siri Merger Sub, Inc., our wholly owned subsidiary ("Merger Sub"), pursuant to which we and Treeline will combine in an all-stock merger. Pursuant to the Merger Agreement, Merger Sub will merge with and into Treeline, with Treeline surviving as our wholly owned subsidiary (the "Merger") and, together with the other transactions contemplated by the Merger Agreement, the “Transactions”). At the effective time of the Merger (the “Effective Time”), we will be renamed Treeline Biosciences Holdings, Inc. and will effect a reverse stock split of our outstanding common stock, if not effected prior to the Effective Timeas permitted by the Merger Agreement.

At the Effective Time, each outstanding share of Treeline capital stock will be converted into the right to receive shares of our common stock based on an exchange ratio calculated in accordance with the Merger Agreement (the “Exchange Ratio”). The Exchange Ratio is based on the relative capitalization of Treeline and Standard BioTools and assumes an equity value for Treeline of $2.5 billion and an equity value for Standard BioTools of $460 million. Following the closing (the “Closing”), our existing stockholders are expected to hold approximately 16% of the combined company on a fully diluted basis, and former Treeline stockholders are expected to hold approximately 84%, subject to adjustment in accordance with the Merger Agreement.

Prior to the Effective Time, we expect to declare a dividend to our stockholders of one contingent value right (“CVR”) for each outstanding share of our common stock. Each CVR will entitle the holder to receive, for each 12-month payment period during the five-year term of the CVR agreement (the “CVR Agreement”, a pro rata portion of the net proceeds received by the combined company from specified sources, less certain permitted deductions, including proceeds from the sale, disposition, or other monetization of our mass cytometry and microfluidics businesses (the “Legacy Business”); proceeds from convertible notes or other investments held by us as of the closing date (the “Closing Date”); contingent payments due to us under contracts in effect as of the

19

Closing Date, including the contingent consideration from Illumina described in Note 3 to our accompanying financial statements appearing elsewhere in this Quarterly Report on Form 10-Q; and certain other amounts specified in the CVR agreement. Payments in respect of the CVRs will be settled in shares of the combined company's common stock, subject to a maximum of 76.0 million shares issuable under the CVR Agreement.

Under the Merger Agreement, we must use commercially reasonable efforts to effect the sale, license, transfer, disposition, divestiture or other monetization of our mass Legacy Business. If we have not entered into a definitive agreement for the disposition of any portion of these businesses on or before the date the registration statement on Form S-4 filed in connection with the Merger is declared effective, we are required to commence mutually agreed wind-down activities with respect to that portion of the business.

Completion of the Merger is subject to customary closing conditions, including approval by our stockholders of the share issuance and an amendment to our certificate of incorporation, effectiveness of the registration statement on Form S-4, continued listing of our common stock on Nasdaq and approval for listing of the shares issuable in the Merger, and expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act. The Merger is expected to close in the second half of 2026. If the Merger is not consummated by March 31, 2027, either party may terminate the Merger Agreement. Upon termination under specified circumstances, we may be required to pay Treeline a termination fee of $16.1 million or to reimburse Treeline's transaction expenses up to $5.0 million.

Divestiture

On June 22, 2025, we entered into a Stock Purchase Agreement (the “Purchase Agreement”) with Illumina, Inc. (“Illumina”) pursuant to which 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 that operated our aptamer-based and functional proteomics business, including KREX, Single SOMAmer, translational and diagnostic assays (collectively, the “SomaScan Business”) (such transaction, the “Transaction”). The Transaction did not include our Legacy Business, which we retained. The Transaction closed on January 30, 2026.

At closing, we received net cash consideration of $388.2 million, which includes $25.0 million of contingent consideration received, that was based on the achievement of specified revenue thresholds during fiscal year 2025. In addition, we are 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. We will recognize the contingent earnout consideration as it is realized.

In addition, at the closing of the Transaction, as additional consideration, we and Illumina entered into (i) a royalty agreement, pursuant to which we are 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 us 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 we are 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.

Restructuring Activities

On August 28, 2025, we initiated a plan to consolidate our South San Francisco-based R&D capabilities into our Singapore facility to co-locate with our manufacturing operations and implemented a reduction in force of certain U.S. employees in our R&D function, including members of our management team. As part of this consolidation, we transferred our headquarters to Boston, Massachusetts and vacated our South San Francisco office on December 31, 2025.

On September 13, 2025, we commenced an additional restructuring plan, including an additional reduction in force to align operating costs with revenue projections for our continuing operations.

Both restructuring actions were designed to improve operational efficiency while supporting the execution of our long-term strategic plan. When combined, the reductions-in-force impacted approximately 20% of our total global workforce.

Factors Affecting Our Performance

Instrument Sales

Instrument sales serve as a key indicator of current business performance and provide visibility into future consumables demand. We anticipate continued growth in our installed base as we deepen market penetration and introduce enhanced capabilities that address evolving customer needs.

20

Our strategy to grow instrument sales includes expanding our global commercial reach, optimizing pricing strategies, and advancing the technological capabilities and applications of our platforms. We actively engage with customers to understand their research priorities and direct our development efforts toward platform enhancements and new applications, which we believe drives adoption of both our instruments and consumables.

Consumables Revenue

Consumables represent a critical component of our revenue model and reflect ongoing customer engagement with our platforms. We monitor consumables trends across our product portfolio and customer segments to inform commercial and development decisions. We expect consumables revenue to grow over time through increased utilization by existing customers, expansion of our installed base, and the introduction of new consumables offerings. Consumables are expected to remain a substantial portion of our total revenue.

Financial Operations Overview

Revenue

We generate our revenue from the sale of products and services. We also derive revenue from collaborative arrangements, license agreements, grants, and royalties. Customers include top biopharmaceutical companies and leading academic research universities. We expect the average selling prices of our products and services to fluctuate over time based on market conditions, product mix and currency fluctuations.

Product revenue

We generate product revenue from the sale of instruments and consumables. Consumables revenue is largely driven by the size of our active installed base of instruments and the level of usage per instrument.

Service revenue

Service revenue primarily consists of post-warranty service contracts, preventive maintenance plans, installation and training for our instruments.

Cost of Revenue

Cost of product revenue

Cost of product revenue consists primarily of raw materials, equipment and production costs, salaries and other personnel costs, overhead and other direct costs related to product revenue. In addition, cost of product revenue includes amortization of developed technology, royalty costs for licensed technologies included in our products, warranty costs, provisions for excess and obsolete inventory, and stock-based compensation expense, and shipping and handling costs. Cost of product revenue is recognized in the period the related revenue is recognized. Shipping and handling costs incurred for product shipments are included in cost of product revenue in the consolidated statements of operations. Our cost of product revenue and related product margin may fluctuate depending on the capacity utilization of our manufacturing facilities in response to market conditions and the demand for our products.

Cost of service revenue

Cost of service revenue consists of raw materials and production costs, personnel-related costs, overhead and other direct costs. Cost of service revenue is recognized in the period the related revenue is recognized.

Our cost of service revenue and related service margin may fluctuate depending on the variability in material and labor costs of servicing.

Research and Development (“R&D”)

R&D expenses consist primarily of personnel-related costs related to enhancing our technologies and supporting development and commercialization of new and existing products and services. R&D expenses also consist of laboratory supply costs, clinical study costs, consulting fees, and other allocated overhead expenses.

Selling, General, and Administrative (“SG&A”)

SG&A expenses consist primarily of personnel costs for our sales and marketing, business development, finance, legal, human resources, information technology and general management teams, as well as professional services, including legal and accounting services.

21

Restructuring and Related Charges

Restructuring and related charges primarily consist of severance costs related to our recent reduction-in-force and facilities costs for floors we have subleased or have the intent to sublease (net of sublease income) under our South San Francisco facility lease. These costs, including a reduction in force, are incurred to improve operational efficiency, achieve cost savings and align our workforce to the future needs of the business.

Transaction and Integration Expenses

Transaction and integration expenses consist of costs incurred in connection with acquisition- and divestiture-related activities, including legal, advisory, accounting and other transaction-related costs including integration costs.

Loss from Discontinued Operations

Loss from discontinued operations represents the results of operations for business components that are classified as held-for-sale and meet the criteria for discontinued operations accounting under ASC 205, Presentation of Financial Statements. This includes the operating results of the discontinued components during the periods presented.

The loss from discontinued operations is presented net of applicable income taxes and includes direct incremental costs associated with the disposal activities, such as legal, advisory, and other transaction-related costs. Any intercompany transactions between continuing and discontinued operations have been eliminated, and certain allocations of corporate overhead and shared costs previously allocated to the discontinued operations have been adjusted to reflect the costs that will be eliminated upon disposal.

Prior period amounts have been reclassified to conform to the current period presentation.

For the three months ended June 30, 2026, total revenue decreased $1.7 million, or 8%, compared to the prior year period. The decrease was driven primarily by a $1.1 million, or 10%, decline in consumables revenue and a $0.5 million, or 8%, decline in services and other revenue. Instrument revenue was substantially unchanged compared to the prior year period.

For the six months ended June 30, 2026, total revenue decreased $0.7 million, or 2%, compared to the prior year period. In the first quarter of 2026, total revenue increased $0.9 million, or 5%, compared to the prior year quarter, driven primarily by higher consumables revenue and partially offset by a decline in instrument revenue. In the second quarter of 2026, total revenue decreased $1.7 million, or 8%. First quarter growth therefore offset the majority of the second quarter decline in the year-to-date results.

Cost of Revenue and Gross Profit

Cost of revenue, gross profit, and gross margin were as follows ($ in thousands):

|  | Three Months Ended June 30, |  |  | Year-over-Year Change |  |  | Six Months Ended June 30, |  |  | Year-over-Year Change |
|  | 2026 |  |  | 2025 |  |  | $ |  |  | % |  |  | 2026 |  |  | 2025 |  |  | $ |  |  | % |

Cost of service revenue |  |  | 2,772 |  |  |  | 3,526 |  |  |  | (754 | ) |  |  | (21 | )% |  |  | 4,904 |  |  |  | 6,268 |  |  |  | (1,364 | ) |  |  | (22 | )%
Total cost of revenue |  | $ | 9,569 |  |  | $ | 11,134 |  |  | $ | (1,565 | ) |  |  | (14 | )% |  | $ | 19,407 |  |  | $ | 20,307 |  |  | $ | (900 | ) |  |  | (4 | )%
Gross profit |  | $ | 10,535 |  |  | $ | 10,628 |  |  | $ | (93 | ) |  |  | (1 | )% |  | $ | 21,843 |  |  | $ | 21,677 |  |  | $ | 166 |  |  |  | 1 | %

For the three months ended June 30, 2026, gross profit decreased $0.1 million, or 1%, compared to the prior year period, primarily due to the decline in our revenue.

For the six months ended June 30, 2026, gross profit increased $0.2 million, or 1%, compared to the prior year period, as lower cost of revenue more than offset the decline in our revenue.

Operating Expenses

Operating expenses were as follows ($ in thousands):

|  | Three Months Ended June 30, |  |  | Year-over-Year Change |  |  | Six Months Ended June 30, |  |  | Year-over-Year Change |
|  | 2026 |  |  | 2025 |  |  | $ |  |  | % |  |  | 2026 |  |  | 2025 |  |  | $ |  |  | % |

23

Research and Development

For the three months ended June 30, 2026, R&D expense decreased by $4.2 million, or 68%, compared to the prior year period. The reduction in R&D expense was primarily driven by a decrease in personnel-related costs due to restructuring activities undertaken during 2025.

For the six months ended June 30, 2026, R&D expense decreased $7.6 million, or 65%, compared to the prior year period. The reduction reflects the deferral of long-horizon R&D projects, which reduced material and supply costs as well as consulting fees. Additionally, the current period benefited from restructuring activities completed in 2025, which reduced corporate overhead costs and personnel-related costs.

Selling, General and Administrative

For the three months ended June 30, 2026, SG&A expense decreased by $11.7 million, or 42%, compared to the prior year period. The reduction in SG&A expense was primarily driven by a decrease in personnel-related costs due to restructuring activities undertaken during 2025.

For the six months ended June 30, 2026, SG&A expense decreased by $22.9 million, or 40%, compared to the prior year period. The decrease primarily reflects a $10.3 million reduction in personnel-related costs and a $4.3 million reduction in stock-based compensation expense due to restructuring activities undertaken in 2025. Additionally, marketing and advertising expense declined by $2.4 million, and consulting fees declined by $1.8 million due to an increased focus by management on expense reduction during 2026.

Restructuring and Related Charges

Restructuring and related charges for the three and six months ended June 30, 2026 increased by $1.1 million and $2.6 million, or 63% and 80%, respectively, compared to the prior year periods. The increase was primarily driven by an increase in facilities-related charges associated with our former South San Francisco office, which was vacated in connection with the consolidation of our R&D function into our Singapore facility in 2025.

Transaction and Integration Expenses

Transaction and integration expenses for the three and six months ended June 30, 2026 increased by $14.5 million and $13.3 million, respectively, compared to the prior year periods. The costs incurred were primarily incurred in connection with the Merger Agreement with Treeline.

Interest Income, net

Interest income, net increased by $2.2 million and $2.8 million, or 88% and 51%, during the three and six months ended June 30, 2026 compared to the prior year periods. The increase was primarily attributable to higher money market fund and investment balances resulting from cash proceeds received in connection with the sale of the SomaScan Business.

Other (Expense) Income, net

For the three months ended June 30, 2026, other (expense) income, net decreased by $5.6 million compared to the prior year period. The decrease was primarily driven by $1.5 million of foreign currency exchange losses in the current period compared to $5.0 million of foreign currency exchange gains in the prior year period, partially offset by $1.0 million of unrealized gains on our equity investments.

For the six months ended June 30, 2026, other (expense) income, net decreased by $11.8 million compared to the prior year period. The decrease primarily reflects $4.8 million of foreign currency exchange losses and $1.4 million of net losses on our equity investments, consisting of $2.5 million of unrealized losses partially offset by $1.2 million of realized gains. The prior year period included $1.9 million of foreign currency exchange gains, a $3.4 million gain from the remeasurement of a contingent consideration liability, and a $0.2 million gain from the remeasurement of warrants, with no comparable remeasurement activity during the six months ended June 30, 2026.

24

Income (loss) from discontinued operations

Loss from discontinued operations decreased by $10.6 million for the three months ended June 30, 2026, compared to the corresponding period in 2025. The decrease occurred because the SomaScan Business was sold in January 2026, and therefore the only discontinued operations activity during the second quarter of 2026 related to $4.2 million of indemnification expense recorded during the period.

Income from discontinued operations increased by $154.9 million for the six months ended June 30, 2026, compared to the corresponding period in 2025. The increase was driven by the gain on sale recorded for the SomaScan Business during 2026.

Liquidity and Capital Resources

We have experienced operating losses since inception and have an accumulated deficit of $1,160.2 million as of June 30, 2026. To date, we have funded our operating losses primarily through acquisitions, divestitures, equity offerings, term loans, convertible notes and redeemable preferred stock. Our ability to fund future operations and meet debt covenant requirements will depend upon our level of future revenue and operating cash flow and our ability to access additional funding through acquisitions, divestitures, equity offerings, or issuances of debt instruments.

Our liquidity and capital requirements depend upon many factors, including market acceptance of our products and services; effectiveness of our business improvement initiatives and restructuring programs; costs of supporting sales growth, product quality, R&D and capital expenditures, including our enterprise resource planning upgrade; and costs and timing of acquiring other businesses, assets or technologies or disposing of our businesses, assets or technologies.

We continually evaluate our liquidity requirements considering our operating needs, growth initiatives and capital resources. We expect that our existing liquidity and sources of capital will be sufficient to support our operations for at least the next 12 months from the filing date of this Quarterly Report on Form 10-Q.

Sources of Liquidity

Our principal sources of liquidity are cash, cash equivalents and investments. Our collective balances of cash, cash equivalents and investments were $544.0 million and $213.3 million at June 30, 2026 and December 31, 2025, respectively.

Capital Resources and Commitments

We have entered into arrangements that serve as sources of capital and the associated contractual agreements may result in firm or contingent obligations of us. In addition to our common stockholders’ equity, our sources of capital have historically included debt and operating leases. Our operating lease arrangements require cash repayment, and our convertible debt contains rights that may result in their conversion to our common stock prior to maturity. However, as of June 30, 2026, we have repaid the majority of our traditional debt obligations and no longer maintain access to credit facilities. Accordingly, our ongoing sources of capital are primarily limited to equity and cash generated from operations.

We also enter into contractual and legally binding commitments to purchase goods. Most of these contracts are cancellable with little or no notice or penalty. However, once a vendor has incurred costs to fulfill a contract with us, and which costs cannot be otherwise deployed, we are liable for those costs upon cancellation.

Cash Flow Activity

Our cash flow summary was as follows ($ in thousands):

|  | Six Months Ended June 30, |
|  | 2026 |  |  | 2025 |
Cash flow summary: |  |  |  |  |  |
Net cash used in operating activities |  | $ | (56,908 | ) |  | $ | (50,951 | )
Net cash provided by investing activities |  |  | 205,498 |  |  |  | 42,130 |
Net cash used in financing activities |  |  | (178 | ) |  |  | 62 |
Effect of foreign exchange rate fluctuations on cash and cash equivalents |  |  | 409 |  |  |  | 1,145 |
Net (decrease) increase in cash, cash equivalents and restricted cash |  | $ | 148,821 |  |  | $ | (7,614 | )

25

We derive cash flows from operations primarily by collecting amounts due from sales of our products and services, and fees earned under our product development and license agreements. Our cash flows from operating activities are also significantly influenced by our use of cash for operating expenses and working capital to support the business. We have historically experienced negative cash flows from operating activities as we have expanded our business and built our infrastructure, domestically and internationally.

In the six months ended June 30, 2026, we used $56.0 million of proceeds from the sale of the SomaScan Business to help fund $56.9 million of net cash used in operating activities. In the six months ended June 30, 2025, we used $49.1 million of net proceeds from the sales and maturities of investments to help fund $51.0 million of net cash used in operating activities.

Operating Activities

Net cash used in operating activities increased by $6.0 million for the six months ended June 30, 2026 compared to the same period in 2025. The increase was attributable to the first quarter of 2026, during which net cash used in operating activities increased $16.3 million compared to the prior year quarter, primarily reflecting $12.1 million of higher transaction and restructuring cost payments and a $10.1 million increase in bonus payments. In the second quarter of 2026, net cash used in operating activities decreased approximately $10.3 million compared to the prior year quarter, reflecting lower cash payments for ongoing operating expenses as a result of our cost reduction initiatives.

Investing Activities

Net cash provided by investing activities was $205.5 million for the six months ended June 30, 2026, compared to $42.1 million for the same period in 2025. The increase was primarily attributable to $388.2 million of cash consideration received in connection with the sale of the SomaScan Business, partially offset by $181.8 million of net purchases of investments funded with a portion of the sale proceeds.

Critical Accounting Policies and Estimates

Management’s discussion and analysis of our financial condition and results of operations are based on our unaudited condensed consolidated financial statements and related notes, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires the use of estimates and assumptions to determine the value of the assets, liabilities, revenues and expenses reported on the condensed consolidated balance sheets and statements of operations. We develop these estimates after considering historical transactions, the current economic environment and various other assumptions considered reasonable under the circumstances. Actual results may differ materially from these estimates and judgments. Accounts that rely heavily on estimated information to determine their values include revenue, trade receivables, inventories, right-of-use assets, lease liabilities and income tax liabilities (assets). Refer to Item 7 in our Annual Report for additional information regarding our critical accounting policies and estimates to which there have been no changes from those described in the Annual Report.

Recent Accounting Pronouncements

From time to time, new accounting standards are issued by the Financial Accounting Standards Board or other standard setting bodies and adopted by us as of the specified effective date. Unless otherwise discussed, the impact of recently issued standards that are not yet effective will not have a material impact on our financial position or results of operations upon adoption.

Item 3. Quan titative and Qualitative Disclosures About Market Risk

Market risk represents the risk of loss that may impact our financial position due to adverse changes in financial market prices and rates. Our market risk exposure is primarily the result of fluctuations in interest rates and foreign exchange rates, as well as, to a lesser extent, inflation and capital market risk.

Interest Rate Risk

We are exposed to interest rate risk in the ordinary course of our business. Our cash and cash equivalents are comprised of funds held in checking accounts and money market accounts. The primary objective of our cash investment activities is to preserve our capital for the purpose of funding operations.

Foreign Currency Risk

26

Due to our operations outside of the United States, we are exposed to market risk related to changes in foreign currency exchange rates. Historically, we have not hedged our foreign currency exposure. Changes in the relative values of currencies occur regularly and, in some instances, could materially adversely affect our business, our financial condition, our results of operations or our cash flows. For the six months ended June 30, 2026, we recognized $4.8 million of foreign currency exchange losses due to changes in foreign currency exchange rates. For the six months ended June 30, 2025, we recognized [$1.9 million] of foreign currency exchange gains due to changes in currency exchange rates.

Inflation Risk

We do not believe that inflation had a material effect on our business, financial condition, results of operations or cash flows in the last two years. If global inflation trends continue, we expect appreciable increases in labor and other operating costs.

Capital Market Risk

We generate our revenue from the sale of products and services and from collaborative arrangements, license agreements, grants, and royalties, but we may in the future raise funds through other sources. One possible source of funding is through further securities offerings. Our ability to raise funds in this manner depends upon capital market forces affecting our stock price, among other things.

Item 4. Cont rols and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer (“CEO”) and our Chief Financial Officer (“CFO”), evaluated the effectiveness of our disclosure controls and procedures as of June 30, 2026. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to our management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of June 30, 2026, our CEO and CFO concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control Over Financial Reporting

There have been no changes in our internal control over financial reporting that occurred during the three months ended June 30, 2026 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Limitations on the Effectiveness of Controls

Control systems, no matter how well conceived and operated, are designed to provide a reasonable, but not an absolute, level of assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. Because of the inherent limitations in any control system, misstatements due to error or fraud may occur and not be detected.

27

PART II. OTHER INFORMATION

Item 1. L egal Proceedings

Information with respect to certain legal proceedings is included in Note 6 to our accompanying financial statements appearing elsewhere in this Quarterly Report on Form 10-Q.

Item 1A. Ri sk Factors

We operate in a rapidly changing environment that involves numerous uncertainties and risks. You should carefully consider the risk factors discussed in this Item 1A, as well as those risk factors discussed in Part I Item 1A “Risk Factors” in our Annual Report which could materially affect our business, financial condition or results of operations. The risks below and the risks in our Annual Report are not the only ones we face. Our business is also subject to the risks that affect many other companies, such as employee relations, general economic conditions, global geopolitical events and international operations. Further, additional risks not currently known to us or that we currently believe are immaterial may in the future materially and adversely affect our business, operations, liquidity and stock price. If any of these risks occur, our business, results of operations or financial condition could suffer, the trading price of our securities could decline, and you may lose all or part of your investment.

Risks Related to Our Common Stock

We could fail to maintain the listing of our common stock on the Nasdaq Stock Market LLC (“Nasdaq”), which could seriously harm the liquidity of our shares and our ability to raise capital or complete a strategic transaction.

Nasdaq has established continued listing requirements, including a requirement to maintain a minimum closing bid price of at least $1.00 per share. On April 20, 2026, we received a written notice from Nasdaq notifying us that, because the closing bid price for our common stock had fallen below $1.00 per share for 30 consecutive business days, we no longer met the minimum bid price requirement (the “Bid Price Requirement”) for continued inclusion on The Nasdaq Global Select Market. Under Nasdaq Listing Rule 5810(c)(3)(A), we had a 180-calendar day period, or until October 19, 2026, to regain compliance with the Bid Price Requirement. On June 5, 2026, we received a letter from the Listing Qualifications Department indicating that we had regained compliance with the Bid Price Requirement, as our common stock had a minimum closing bid price of at least $1.00 per share for a minimum of 10 consecutive business days during the 180-calendar day period.

On July 22, 2026, we received a written notice from Nasdaq notifying us that we again did not meet the Bid Price Requirement. Under Nasdaq Listing Rule 5810(c)(3)(A), we have a 180-calendar day period, or until January 19, 2027 (the “Compliance Date”), to regain compliance with the Bid Price Requirement. If we do not regain compliance by the Compliance Date, we may be eligible for an additional 180-calendar day period, subject to satisfying the conditions in the applicable Nasdaq Listing Rules. There can be no assurance that we will be able to regain compliance with the bid price requirement within the 180-calendar day compliance period provided by Nasdaq rules or maintain compliance with other Nasdaq requirements in the future. If we are not able to maintain compliance with Nasdaq requirements, our common stock may be delisted from Nasdaq, which could have a material adverse effect on us and our stockholders, including by reducing the liquidity of our shares and having a material adverse effect on our ability to raise capital or complete a strategic transaction.

Risks Related to the Merger with Treeline

We and Treeline may not be successful in consummating the Merger.

There can be no assurance that the Merger with Treeline will be successfully consummated or lead to increased stockholder value. The completion of the Merger is dependent on a number of factors that may be beyond our control, including, among other things, market conditions, regulatory approval and stockholder approval. Any failure to consummate the Merger would have a material adverse effect on our business and could significantly impair our ability to enter into alternative strategic transactions.

The process of completing the Merger is costly, time-consuming and complex. We have incurred, and may in the future incur, significant costs related to the Merger, including legal and accounting fees and expenses and other related charges, which have been and will be incurred regardless of whether the Merger is completed. We may also incur additional unanticipated expenses in connection with the Merger. These expenses will decrease the remaining cash available for use in our business. Also, the Merger could have a variety of negative consequences, or yield unexpected results, that adversely affect our business and decrease the remaining cash available for use in the combined company’s future business.

If the Merger is not completed in a timely fashion, we may experience reputational harm and the value of our common stock may be adversely impacted. In addition, speculation regarding the completion of the Merger and perceived uncertainties related to our future

28

could cause our stock price to fluctuate significantly. Also, if the Merger Agreement is terminated and our board of directors determines to seek another business combination, there can be no assurance that we will be able to find another third party to transact a business combination with, yielding comparable or greater benefits.

The consummation of the Merger is subject to various conditions, including approval by our stockholders, regulatory approval and obtaining approval by Nasdaq to list our common stock. Failure to satisfy these conditions would prevent the Closing.

The Merger Agreement contains a number of conditions that must be satisfied or waived (to the extent permitted by applicable law) in order to consummate the Merger, some of which are not within our control. These conditions include, among others:

• | approval of certain matters related to the Merger by our stockholders;
• | approval for listing on Nasdaq of our common stock to be issued to Treeline stockholders in connection with the Merger, subject to official notice of issuance;
• | expiration or termination of the waiting period relating to the Merger under applicable antitrust laws (which occurred in July 2026);
• | the absence of any law, judgment, order or other legal restraint prohibiting the Merger; and
• | the effectiveness of a registration statement on Form S-4.

Any failure to satisfy or, to the extent permitted by applicable law, waive these required closing conditions may prevent, delay or otherwise materially adversely affect the consummation of the Merger. We cannot predict with certainty whether or when any of the required conditions will be satisfied or, to the extent permitted by applicable law, waived, and cannot assure you that we will be able to successfully consummate the Merger as currently contemplated under the Merger Agreement or at all.

In addition, the Merger might not be consummated because Treeline or we may elect to terminate the Merger Agreement in certain circumstances. Upon termination of the Merger Agreement under specified circumstances, including if Treeline terminates the Merger Agreement due to a change in our board recommendation in favor of the Transactions, we will be required to make a payment to Treeline equal to $16.1 million in cash. In addition, we will be required to reimburse Treeline’s reasonable out-of-pocket fees in connection with the Transactions up to a maximum of $5 million if the Merger Agreement is terminated due to a failure to obtain the required approval of our stockholders.

The Merger consideration paid at Closing may have a greater or lesser value than at the time the Merger Agreement was signed or at the time of the special meeting of stockholders related to the Merger. The value of the Merger consideration will be impacted by fluctuations in the market price of our common stock.

In connection with the Closing of the Merger, each share of Treeline common stock and Treeline preferred stock issued and outstanding immediately prior to the Effective Time will be converted into the right to receive a number of shares of our common stock based on the Exchange Ratio calculated in accordance with the Merger Agreement , provided that the number of shares of our common stock which each holder of Treeline capital stock is entitled to receive will be rounded down to the nearest whole share and computed after aggregating all shares of Treeline capital stock held by such holder, with no cash payable in lieu of fractional shares.

The Exchange Ratio will not be adjusted in the event of any change in the market price of our common stock and, as a result, prior to the Effective Time, our stockholders cannot be sure of the value of our common stock to be issued in connection with the Merger. Changes in our stock price can result from a variety of factors, including general market, industry and economic conditions, changes in Treeline’s and our respective businesses, operations and prospects, regulatory considerations, results of the special meeting of our stockholders at which the stockholders will be asked to vote on proposals related to the approval of the Merger (the “Special Meeting”), announcements with respect to the Merger or any of the foregoing, and other factors beyond our control.

The exact dollar value of the shares of our common stock that stockholders of each company will hold upon consummation of the Merger will not be known at the time of the Special Meeting and may be greater than, the same as or less than the market price of our common stock at the time of the Special Meeting. The market price of our common stock is subject to general price fluctuations in the market for publicly traded equity securities and has experienced volatility in the past and may vary significantly after the date of the Special Meeting. As a result of these fluctuations, the value of the Merger consideration will also vary.

The Exchange Ratio, which determines the number of shares to be issued to the Treeline stockholders, will vary based on the extent to which Parent Net Cash at Closing is more than $451 million or less than $449 million.

The value of the Merger consideration will also be impacted by the amount of Parent Net Cash (as defined in the Merger Agreement) that we have at Closing. The Exchange Ratio, which determines the number of shares of our common stock to be issued to former Treeline stockholders, will vary in part based on the amount of Parent Net Cash that we have at Closing. To the extent that Parent Net

29

Cash is more than $451 million, the Exchange Ratio will be lower and Treeline stockholders will receive fewer shares of our common stock; to the extent that Parent Net Cash is less than $449 million, the Exchange Ratio will be higher and Treeline stockholders will receive more shares of our common stock, resulting in incremental dilution to our stockholders. The term “Parent Net Cash,” as defined in the Merger Agreement, will be reduced by the amount of certain of our liabilities at Closing.

The Merger Agreement contains provisions that could discourage a potential competing acquirer of us or Treeline.

The Merger Agreement contains “no shop” provisions that restrict each of our and Treeline’s ability to solicit, initiate, induce, knowingly encourage or knowingly facilitate, or take any other action designed to facilitate, competing third-party proposals relating to a merger, reorganization or consolidation of the respective company or an acquisition of the respective company’s stock or assets. In addition, we generally have an opportunity to offer to modify the terms of the Merger Agreement in response to any competing acquisition proposals before our board may withdraw or qualify its recommendation with respect to the Merger. If the Merger Agreement is terminated in connection with our pursuit of a third-party transaction, we will be required to pay a termination fee of $16.1 million to Treeline and/or reimburse up to a maximum of $5 million of Treeline’s expenses.

These provisions could discourage a potential third-party acquirer that might have an interest in acquiring all or a significant portion of our company from considering or proposing an acquisition, even if it were prepared to pay consideration with a higher per share cash or market value than the market value proposed in the Merger. A potential third-party acquirer maintaining interest in the face of these provisions might propose to pay a lower price to our stockholders than it might otherwise have proposed to pay because of the added expense of the termination fee and expense reimbursement described above.

If the Merger Agreement is terminated and we determine to seek another business combination, we may not be able to negotiate a transaction with another party on terms comparable to, or better than, the terms of the Merger.

The pendency of the Merger could materially adversely affect our business, financial condition, results of operations or cash flows.

The announcement and pendency of the Merger could disrupt our business in any of the following ways, among others:

• | our employees may experience uncertainty about their future roles with the combined company, which might adversely affect our ability to retain and hire key managers and other employees;
• | the attention of our management may be directed toward completion of the Merger and transaction-related considerations and may be diverted from our day-to-day business operations and, following the completion of the Merger, the attention of the combined company’s management may also be diverted to such matters;
• | vendors, suppliers, business partners or others may seek to modify or terminate their business relationship with us or the combined company following completion of the Merger;
• | we or the combined company following completion of the Merger and their respective officers and directors could become subject to lawsuits relating to the Merger; and
• | we may experience negative reactions from our stockholders, among others.

These disruptions could be exacerbated by a delay in the completion of the Merger or termination of the Merger Agreement. Additionally, if the Merger is not consummated, we will have incurred significant costs and diverted the time and attention of management. A failure to consummate the Merger may also result in negative publicity, reputational harm, litigation against us or our directors and officers, and a negative impression of the companies in the financial markets. The occurrence of any of these events individually or in combination could have a material adverse effect on our financial performance and stock price.

The interim operating covenants contained in the Merger Agreement may prevent us from pursuing opportunities that would be beneficial to our stockholders.

The Merger Agreement restricts us from taking certain actions until the Effective Time without the consent of Treeline, including, among others: the payment of dividends; the issuance of equity (including certain equity incentive awards); certain increases to employee compensation and benefits; capital expenditures; the incurrence of indebtedness; acquisitions and divestitures; and the entry into or amending certain material contracts. We are required to conduct our business in the ordinary course of business in all material respects.

The restrictive covenants, which are subject to various specific exceptions, may prevent us from pursuing attractive business opportunities that may arise prior to the consummation of the Merger. Although we may be able to pursue such activities with Treeline’s consent, there is no assurance that Treeline will be willing to provide its consent.

30

The Merger may be completed even though a material adverse effect may result from the announcement of the Merger, industry-wide changes or other causes.

In general, neither we nor Treeline is obligated to complete the Merger if there is a continuing material adverse effect affecting the other party between June 6, 2026, the date of the Merger Agreement, and the Closing. However, certain types of changes are excluded from the concept of a “material adverse effect.”

Such exclusions include, but are not limited to, general business or economic conditions generally affecting the industry in which the applicable party operates; political conditions, acts of war, the outbreak or escalation of armed hostilities, acts of terrorism, earthquakes, wildfires, hurricanes, tsunamis, floods, mudslides, weather conditions, other natural disasters, man-made disasters, health and other emergencies, calamities, epidemics, pandemics (including COVID-19 and any evolutions or mutations thereof), disease outbreaks, other acts of God or force majeure events; changes in financial, banking or securities markets, including changes in interest rates in the United States or any other country or region in the world; any change in law or GAAP; any change in the stock price or trading volume of our common stock; a failure to meet internal or analysts’ expectations or projections; and the execution or announcement of the Merger Agreement or the pendency of the Merger.

Therefore, if any of these events were to occur, impacting us or Treeline, the other party would still be obliged to consummate the Closing. If any such adverse changes occur and we and Treeline consummate the Closing, the stock price of the combined company may suffer. This in turn may reduce the value of the Merger to our stockholders.

If we and Treeline complete the Merger, the combined company may need to raise additional capital in the future by issuing equity securities or additional debt or through licensing arrangements, which may cause significant dilution to the combined company’s stockholders or restrict the combined company’s operations.

Additional financing may not be available to the combined company when it is needed or may not be available on favorable terms. To the extent that the combined company raises additional capital by issuing equity securities, or debt securities convertible into equity securities, such financing will cause additional dilution to all of the securityholders of the combined company, including our pre-Merger stockholders and Treeline’s former stockholders, and could have an adverse impact on the combined company’s stock price. It is also possible that the terms of any new equity securities may have preferences over the combined company’s common stock. Any debt financing the combined company enters into may include covenants that restrict its operations. These restrictive covenants may include limitations on additional borrowing and specific restrictions on the use of the combined company’s assets, as well as prohibitions on its ability to create liens, pay dividends, redeem its stock or make investments. In addition, if the combined company raises additional funds through licensing arrangements, it may be necessary to grant licenses on terms that are not favorable to the combined company. Any such financing could have a material adverse effect on the combined company.

Litigation that may be filed against us and/or our officers and directors could prevent or delay the consummation of the Merger.

The outcome of any lawsuit that may be filed challenging the Merger is uncertain. One of the conditions to the Closing is that no applicable law, judgment (whether temporary, preliminary or permanent) or other legal restraint or binding order or determination by any governmental entity of competent jurisdiction shall be in effect that prevents, restrains, enjoins, makes illegal or otherwise prohibits the consummation of the Merger or the Transactions.

Accordingly, if any future lawsuit is successful in obtaining an order enjoining consummation of the Merger, then such order may prevent the Merger from being consummated, or from being consummated within the expected time frame, and could result in substantial costs to us, including but not limited to, legal fees and costs associated with the indemnification of directors and officers. Any such injunction or delay in the Merger being completed may adversely affect our business, financial condition, results of operations, and cash flows.

The business of the combined company following the Merger will be different than our business prior to the Merger.

We currently develop, manufacture and sell a diversified range of instrumentation, consumables, and services that help scientists and biomedical researchers develop better therapeutics faster. Our proprietary multi-omics tools are used in a broad range of applications, including proteomics and genomics, and other areas of translational and clinical research. Our instruments and consumables are sold to leading academic research institutions, translational research and medicine centers, cancer centers, clinical research laboratories, and biopharmaceutical, biotechnology, and plant and animal research companies.

In connection with the Merger, we expect to sell or otherwise monetize our mass cytometry and microfluidics businesses, and the business of the combined company will consist of Treeline’s business. Treeline is a clinical-stage biopharmaceutical company that

31

matches compelling biological targets with proven drug approaches, including small molecule inhibitors, protein degraders, and targeted therapy antibody-drug conjugates, by integrating in-house R&D with leading-edge computational tools. Treeline’s pipeline spans oncology, neurology and immunology.

This change in our business from manufacturing and selling instruments to being a clinical-stage biopharmaceutical company could have a significant impact on the trading and market price of the common stock of the combined company following the Merger. The change in business may attract different investors and analysts and could result in the combined company’s common stock being more volatile than it was prior to the Merger. We cannot predict with certainty how the change in business will impact the combined company’s common stock following the consummation of the Merger. There can be no assurance that the change in business will not have a material adverse impact on the trading price and liquidity of the combined company’s common stock.

Following the consummation of the Merger, the composition of the board of directors and management of the combined company will be different from the composition of our current board of directors and management.

Following the consummation of the Merger, the board of directors of the combined company is expected to consist of 12 members, including ten director designees of Treeline and two of our director designees. In addition, the management team of Treeline will become our management team. In particular, Dr. Joshua Bilenker, currently the chief executive officer and co-founder of Treeline, will serve as Chief Executive Officer of the combined company, Dr. Jeffrey Engelman, currently the chief scientific officer and co-founder of Treeline, will serve as Chief Scientific Officer of the combined company, and Spencer Smith, currently the chief financial officer of Treeline, will serve as Chief Financial Officer of the combined company.

This change in board membership and management of the combined company may affect the combined company’s business strategy and operating decisions following the consummation of the Merger, as compared to our strategy and operating decisions prior to the Merger. In addition, there can be no assurances that the board of directors of the combined company will function effectively as a team and that any differences or difficulties, should they arise, will not have an adverse effect on the combined company’s business or results after the Closing Date.

Following consummation of the Merger, our former stockholders will own less than a majority of the outstanding common stock of the combined company and will therefore have less influence over the combined company than they do now.

Immediately following completion of the Merger and the issuance of our common stock to the Treeline stockholders at the Effective Time, our current stockholders in the aggregate will not have a majority ownership and voting interest in the combined company, which will result in our stockholders having less influence on the combined company’s management and policies. Immediately following completion of the Merger and using an estimated Exchange Ratio based on our and Treeline’s capitalization as of June 3, 2026 and May 28, 2026, respectively, and taking into account our estimated cash position as of the Closing but excluding any effect of our proposed reverse stock split, Treeline stockholders and our stockholders are expected to own approximately 84% and 16%, respectively, of the combined company’s outstanding shares on a fully diluted basis. As a result, our current stockholders will have significantly less influence on the combined company’s management and policies than they currently have.

Because the lack of a public market for the shares of Treeline capital stock makes it difficult to evaluate the fairness of the Merger, we may pay more to the Treeline stockholders than the fair market value of the Treeline capital stock.

The outstanding shares of Treeline capital stock are privately held and are not traded in any public market. The lack of a public market makes it extremely difficult to determine the fair market value of the shares of Treeline capital stock. Because the Exchange Ratio that will be used to calculate the number of shares of our common stock to be issued to Treeline stockholders was determined based on negotiations between the parties, it is possible that we may pay more than the aggregate fair market value for the shares of Treeline capital stock.

Failure to consummate the Merger could negatively impact our future stock prices, operations and financial results.

If the Merger is not consummated for any reason, we may be subject to a number of material risks, including the following:

• | a decline in the market price of our common stock to the extent that its current market price reflects a market assumption that the Merger will be consummated and will be beneficial to the value of the common stock after the Closing Date;
• | having to pay certain costs related to the proposed Merger, such as legal, accounting, financial advisory, printing and mailing fees, which must be paid regardless of whether the Merger is consummated;

32

• | addressing the consequences of operational decisions made since the signing of the Merger Agreement, including decisions made as a result of restrictions on our operations imposed by the terms of the Merger Agreement and decisions to delay or defer capital expenditures;
• | returning the focus of management and personnel to operating our business on a standalone basis, without any of the benefits expected to have been provided by the consummation of the Merger; and
• | negative reactions from stockholders, customers, suppliers and employees.

In addition to the above risks, we may be required, under certain circumstances, to pay a termination fee of $16.1 million to Treeline, including if Treeline terminates the Merger Agreement due to a change in our board recommendation in favor of the Transactions, or in some cases reimburse Treeline’s reasonable out-of-pocket transaction-related expenses (up to a maximum of $5 million), including if Treeline terminates the Merger Agreement due to a failure to obtain the required approval of our stockholders, which may adversely affect our financial condition.

Our business may be adversely impacted by the failure to pursue other beneficial opportunities due to the focus of our management on the Merger. A failure to consummate the Merger may also result in negative publicity, reputational harm, potential litigation against us or our directors and officers, and a negative impression of the companies in the financial markets. If the Merger is not consummated, we cannot assure our stockholders that these risks will not materialize and will not materially adversely affect our business, financial results and stock price.

If the Merger is not completed, and there is no superior alternative transaction available, our board may decide to pursue a dissolution and liquidation of our business. In such an event, the amount of cash available for distribution to our stockholders will depend heavily on the timing of such liquidation as well as the amount of cash that will need to be reserved for commitments and contingent liabilities.

If the Merger is not completed, and there is no superior alternative transaction available, our board may decide to pursue a dissolution and liquidation of our business if it concludes that such strategy is in the best interests of our stockholders. In such an event, the amount of cash available for distribution to our stockholders will depend heavily on the timing of such decision and, with the passage of time, the amount of cash available for distribution will be reduced as we continue to fund our operations.

In addition, if our board were to approve and recommend, and our stockholders were to approve, a dissolution and liquidation, we would be required under Delaware corporate law to pay our outstanding obligations, as well as to make reasonable provision for contingent and unknown obligations, prior to making any distributions in liquidation to our stockholders. As a result of this requirement, a portion of our assets may need to be reserved pending the resolution of such obligations and the timing of any such resolution is uncertain. In addition, we may be subject to litigation or other claims related to a dissolution and liquidation.

If a dissolution and liquidation were pursued, our board, in consultation with our advisors, would need to evaluate these matters and make a determination about a reasonable amount to reserve. Accordingly, holders of our common stock could lose all or a significant portion of their investment in the event of a liquidation, dissolution or winding up.

Our stockholders will not be entitled to appraisal rights in the Merger.

Appraisal rights are statutory rights that, if applicable under law, enable stockholders to dissent from an extraordinary transaction, such as a merger, and to demand that the corporation pay the fair value for their shares as determined by a court in a judicial proceeding instead of receiving the consideration offered to stockholders in connection with the extraordinary transaction.

Under Section 262(b) of the Delaware General Corporation Law, stockholders do not have appraisal rights if the shares of stock they hold, as of the record date for determination of stockholders entitled to vote at the meeting of stockholders to act upon a merger, are either (i) listed on a national securities exchange or (ii) held of record by more than 2,000 holders. Notwithstanding the foregoing, appraisal rights are available if stockholders are required by the terms of the Merger Agreement to accept for their shares anything other than (a) shares of stock of the surviving corporation, (b) shares of stock of another corporation that will either be listed on a national securities exchange or held of record by more than 2,000 holders, (c) cash instead of fractional shares or (d) any combination of clauses (a) through (c).

Because our common stock is listed on The Nasdaq Global Select Market, a national securities exchange, and is expected to continue to be so listed on the record date, our stockholders will not be entitled to appraisal rights in the Merger with respect to their shares of our common stock.

The market price for our common stock following completion of the Merger may fluctuate.

33

The market price of our common stock could fall following the consummation of the Merger. At the Closing, we expect to issue approximately 2 billion shares of our common stock (excluding the effect of any proposed reverse stock split) as merger consideration to the Treeline stockholders. Treeline stockholders may decide not to hold the shares of our common stock they receive in the Merger. Other Treeline stockholders, such as funds with limitations on the amount of stock they are permitted to hold in individual issuers, may be required to sell our common stock that they receive in the Merger. Such sales, or market perception of such sales, of our common stock could result in a higher-than-average trading volume following the Closing and may cause the market price for our common stock to decline.

We or Treeline may waive one or more of the conditions to the Merger.

We or Treeline may agree to waive (to the extent permitted by applicable law), in whole or in part, some of the conditions to each party’s obligations to complete the Merger, to the extent permitted by applicable law. For example, it is a condition to our and Treeline’s respective obligations to close the Merger that certain of the representations and warranties of the other party are true and correct in all respects as of the Closing Date, except where the failure of such representations and warranties to be true and correct would not have a material adverse effect. However, if the board of directors of either party determines that it is in the best interests of the stockholders of that company to waive any breach of representation by the other party, then such board of directors may elect to waive that condition (to the extent permitted by applicable law).

A waiver of any condition may have a material adverse effect on the stockholders of the combined company following the Merger. For example, the market could react negatively to such information, which may cause a substantial decline in the price of the common stock of the combined company following the Merger.

Notwithstanding the foregoing, certain closing conditions may not be waived due to applicable law or otherwise. The following closing conditions may not be waived: receipt of the requisite stockholder approvals; the effectiveness of the registration statement on Form S-4; and the absence of any order or injunction that has the effect of prohibiting the consummation of the Merger. The foregoing closing conditions are the only closing conditions to the Merger that may not be waived. All other closing conditions to the Merger may be waived (to the extent permitted by applicable law) by us and/or Treeline, as applicable.

We might not be able to utilize a significant portion of our net operating loss carryforwards and research and development tax credit carryforwards.

We have incurred significant net losses since our inception and cannot guarantee when, if ever, we will become profitable. Unused net operating loss (“NOL”) and tax credit carryforwards will generally carry forward to offset future taxable income, subject to applicable limitations on the use of those losses. Federal NOLs incurred in taxable years ending on or before December 31, 2017 are eligible to be carried forward for up to 20 years, and to be deducted in full against income for the years to which they may be carried. Federal NOLs incurred in taxable years ending after December 31, 2017 are eligible to be carried forward indefinitely, but may offset no more than 80% of the taxable income for the years to which they are carried (computed without regard to the deduction for carryovers of NOLs). To the extent they expire unused, these NOLs and tax credit carryforwards will not be available to offset our future income tax liabilities.

In addition, under Sections 382 and 383 of the Code, and corresponding provisions of state law, if a corporation undergoes an “ownership change,” which is generally defined as a greater than 50% change, by value, in its equity ownership over a three-year period, the corporation’s ability to use its pre-change NOLs and tax credit carryovers to reduce its tax liability for post-change periods may be limited. We have experienced ownership changes in the past, will experience an ownership change as a result of the Merger, and may experience future ownership changes as a result of subsequent shifts in our stock ownership, some of which may be outside of our control. As a result, our ability to use our historical NOLs and tax credit carryovers to offset future income tax liabilities is limited by prior ownership changes and may become limited by additional ownership changes in the future (including any ownership change resulting from the Merger).

Our stockholders may not receive any payment on the CVRs, and the CVRs may otherwise expire valueless.

As part of the Merger, we may issue CVRs for each outstanding share of our common stock. Pursuant to the terms of a Contingent Value Rights Agreement to be entered into between us and a rights agent, the holder of each CVR will be entitled to receive a payment for each 12-month CVR payment period during the five-year term of the CVR Agreement, consisting of a number of shares of the combined company’s common stock (with fractional shares settled in cash) equal to such holder’s pro rata portion of the aggregate net proceeds received by the combined company during such 12-month CVR payment period from the following sources, in each case less certain permitted deductions: (i) proceeds from any sale, disposition, or other monetization of the Legacy Business; (ii) proceeds from convertible notes or other investments held by us as of the Closing Date; (iii) earnout, milestone, royalty or other

34

similar contingent payments due to us under contracts in effect as of the Closing Date, including payments from Illumina, Inc. pursuant to the Stock Purchase Agreement dated June 22, 2025; and (iv) any surplus in Parent Net Cash delivered at Closing as finally determined under the Merger Agreement.

The right of our stockholders to receive any future payment for or derive any value from the CVRs will be contingent in part upon the combined company’s receipt of (i) proceeds from any sale, disposition, or other monetization of the Legacy Business; (ii) proceeds from convertible notes or other investments held by us as of the Closing Date; (iii) earnout, milestone, royalty or other similar contingent payments due to us under contracts in effect as of the Closing Date, including payments from Illumina, Inc. pursuant to the Stock Purchase Agreement dated June 22, 2025; and (iv) any surplus in Parent Net Cash delivered at Closing as finally determined under the Merger Agreement, and the timing and amount of the consideration received thereunder. If the combined company is not successful in entering into disposition agreements related to the Legacy Business or receiving payments thereunder within the time period specified in the CVR Agreement, there are no proceeds from convertible notes or other investments, there are no earnout, milestone, royalty or other similar payments under our existing contracts, and there is no Parent Net Cash surplus, no payments will be made in respect of the CVRs.

Following the Effective Time, the combined company will have sole authority over whether and how to monetize the Legacy Business (if at all), and the combined company’s only obligations will be to carry out the obligations set forth in the CVR Agreement. Furthermore, the CVRs will be unsecured obligations of the combined company and all payments under the CVRs and all other obligations under the CVR Agreement and the CVRs and any rights or claims relating thereto will be subordinated in right of payment to the prior payment in full of all current or future senior obligations of the combined company. Accordingly, there can be no assurance that holders of CVRs will receive any payments with respect to the CVRs.

Any payments under the CVRs will be made in shares of the combined company’s common stock, subject to the maximum cap of 76,000,000 shares. If substantial payments are made under the CVRs, the issuance of such shares will dilute the ownership percentage of all stockholders of the combined company who are not CVR holders, including former Treeline stockholders. This dilution could be material if the Legacy Business is sold or monetized at a significant value during the CVR payment period. Additionally, any such shares paid in respect of the CVRs will be subject to market conditions and may decline in value following payment.

In addition, CVR holders will have limited ability to transfer their CVRs, which are not registered with the SEC and will not trade on any securities exchange. The CVRs are illiquid instruments with no established market, and CVR holders may be unable to sell, assign or otherwise dispose of their CVRs except in the limited circumstances specified in the CVR Agreement. The illiquidity of the CVRs may make it difficult for CVR holders to realize any value from their CVRs prior to the expiration of the CVR Agreement.

The tax treatment of the CVRs is uncertain.

To the extent that any of our stockholders receive any CVRs, we intend to treat a holder’s receipt of the CVRs as a non-taxable distribution with respect to the holder’s existing shares of our common stock for U.S. federal income tax purposes. However, the U.S. federal income tax treatment of the CVRs is uncertain. There is no legal authority directly addressing the U.S. federal income tax treatment of the receipt of, and payments under, the CVRs, and there can be no assurance that the IRS would not assert, or that a court would not sustain, a position that could result in adverse U.S. federal income tax consequences to holders of the CVRs. For example, the IRS may assert that the distribution of the CVRs is a taxable distribution of property, which would be taxable as a dividend to the extent of the holder’s pro rata share of our current and accumulated earnings and profits, if any, with any excess being treated as a return of capital to the extent thereof and then as capital gain.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

Unregistered Sales of Equity Securities and Use of Proceeds

None.

Issuer Purchases of Equity Securities

On February 6, 2024, our board of directors authorized the 2024 Share Repurchase Program pursuant to which we may repurchase up to $50.0 million of shares of our common stock in the open market, in one or more Rule 10b5-1 trading plans, or in negotiated transactions through March 1, 2026. The repurchases are contingent upon favorable market and business conditions and are funded by cash on hand. The program does not obligate us to acquire any specific number of shares. As of June 30, 2026, we have repurchased 15,448,533 shares of our common stock for an aggregate of $40.5 million under the 2024 Share Repurchase Program. We did not purchase any shares of common stock during the three months ended June 30, 2026.

From time to time, our officers (as defined in Rule 16a-1(f) of the Exchange Act) and directors may enter into Rule 10b5-1 or non-Rule 10b5-1 trading arrangements (as each such term is defined in Item 408 of Regulation S-K). During the three and six months ended June 30, 2026, none of our officers or directors adopted, modified or terminated any such trading arrangements.
