Item 2.05    Item Costs Associated with Exit or Disposal Activities.

On May 7, 2025, the Board of Directors of the Company approved a plan to reduce operating costs and preserve cash. As part of this plan, the Company will reduce its operating expenses by approximately $15 million in 2025, with annualized savings of $30 million, or 15% of the Company's cost base. Approximately $9 million of the $15 million savings will be realized from headcount actions. The remaining savings will be realized from a reduction in other costs. The reduction in force is expected to be substantially completed by the end of the second quarter of 2025. The Company expects to incur expenses of approximately $1.5 million related to the reduction in force, substantially all of which will be cash expenditures incurred in 2025 for severance.

Quanterix’s estimates are based on a number of assumptions. Actual results may differ materially, and additional charges not currently expected may be incurred in connection with, or as a result of, the workforce reduction. As permitted by Item 2.05 of Form 8-K, Quanterix will file an amendment to this report if charges and future cash payments differ materially from current estimates.

Item 1.01     Entry into a Material Definitive Agreement.

Agreement and Plan of Merger

On January 9, 2025, Quanterix Corporation, a Delaware corporation (the “Company” or “Quanterix”), entered into an Agreement and Plan of Merger (the “Merger Agreement”), by and among the Company, Wellfleet Merger Sub, Inc., a Delaware corporation and wholly owned subsidiary of the Company (“Merger Sub”), and Akoya Biosciences, Inc., a Delaware corporation (“Akoya”), pursuant to which, subject to the terms and conditions set forth therein, Merger Sub will merge with and into Akoya (the “Merger”), with Akoya surviving such Merger as a wholly owned subsidiary of the Company.

Merger Consideration

Under the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each share of common stock, par value $0.00001 per share, of Akoya (the “Akoya Common Stock”) outstanding immediately prior to the Effective Time (other than shares held as of the Effective Time by the Company, Merger Sub, any direct or indirect wholly owned subsidiary of the Company or Akoya or by Akoya as treasury shares) will be converted into the right to receive 0.318 (the “Exchange Ratio”) of a fully paid and nonassessable share of common stock, par value $0.001 per share, of the Company (the “Company Common Stock”) and, if applicable, cash in lieu of fractional shares, subject to any applicable withholding.

As of immediately prior to the Effective Time, each restricted stock unit in respect of shares of Akoya Common Stock (each, an “Akoya RSU”) that is outstanding immediately prior to the Effective Time (a “Rollover RSU”) will automatically be converted into a number of restricted stock units with respect to shares of Company Common Stock based on the Exchange Ratio. Such Rollover RSUs will be otherwise subject to the same terms and conditions, including vesting, as were applicable to the relevant Akoya RSU immediately prior to the Effective Time, except that Akoya RSUs that, by their existing terms, provide for vesting acceleration triggered in connection with the Effective Time will be so accelerated in accordance with such terms.

As of immediately prior to the Effective Time, each option to acquire shares of Akoya Common Stock (each, an “Akoya Option”) that is then outstanding immediately prior to the Effective Time (a “Rollover Option”) will automatically be converted into an option to acquire shares of Company Common Stock, with the number of shares of Company Common Stock and the per share exercise price adjusted based on the Exchange Ratio. Such Rollover Options will be otherwise subject to the same terms and conditions, including vesting, as were applicable to the relevant Akoya Option immediately prior to the Effective Time, except that Akoya Options that, by their existing terms, provide for vesting acceleration triggered in connection with the Effective Time will be so accelerated in accordance with such terms.

Item 2.02    Results of Operations and Financial Condition. On November 12, 2024, Quanterix Corporation (the “Company”) issued a press release announcing selected preliminary financial results for the third quarter ended September 30, 2024 and the need to restate certain previously issued financial statements as further described in Item 4.02 below (the “Press Release”). A copy of the Press Release is furnished as Exhibit 99.1 and is incorporated herein by reference. The information contained in paragraph three (inclusive of the table) of Item 4.02(a) and in Exhibit 99.1 of this Current Report on Form 8-K is incorporated into this Item 2.02 by reference. The information incorporated by reference into this Item 2.02 is intended to be furnished under Item 2.02 and shall not be deemed “filed” under Item 2.02 for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended (the “Securities Act”), or the Exchange Act, except as expressly set forth by specific reference in such filing.

Item 4.02    Non-Reliance on Previously Issued Financial Statements or a Related Audit Report or a Completed Interim Review. (a)On November 11, 2024, the Audit Committee of the Board of Directors of the Company, based on the recommendation of the Company’s management and after discussion with the Company’s independent registered public accounting firm, Ernst & Young LLP (“EY”), concluded that the Company’s previously issued audited consolidated financial statements as of December 31, 2023 and 2022 and for each of the three years in the period ended December 31, 2023, and its unaudited consolidated financial statements for the quarterly and year-to-date (as applicable) periods ended March 31, 2022, June 30, 2022, September 30, 2022, March 31, 2023, June 30, 2023, September 30, 2023, March 31, 2024, and June 30, 2024 (collectively, the “Non-Reliance Periods”), should no longer be relied upon. As previously reported and as discussed in more detail below, the Company has identified and continues its efforts to remediate material weaknesses in its internal control over financial reporting relating to, among others, the operating effectiveness of internal control associated with the accounting for inventory valuation. In connection with these remediation efforts, and while performing closing procedures for the third quarter of 2024, management identified an error related to the capitalization of labor and overhead costs applied to prior periods going back to at least 2021, which impacted the valuation of inventory. This error relates to a design deficiency in the Company’s internal control over financial reporting related to the accounting for inventory valuation. The cumulative effect of this error, when taken together with unrelated immaterial errors identified by the Company in prior periods, resulted in the need for material adjustment

On August 8, 2022, Quanterix Corporation (“Quanterix” or, the “Company”) issued a press release announcing its financial results for the second quarter ended June 30, 2022 (the “Earnings Release”).  A copy of the Earnings Release is furnished as Exhibit 99.1 and is incorporated herein by reference.

Except as set forth below, the information in this Item 2.02 (including Exhibit 99.1) shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934 (the “Exchange Act”) or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933 or the Exchange Act, except as expressly set forth by specific reference in such a filing.

Item 2.05Costs Associated with Exit or Disposal Activities.

Following a strategic review and top-down assessment

of its operations, on August 8, 2022, the Company announced a plan of restructuring and strategic re-alignment, which includes the elimination of approximately 130 positions across the Company and other cost-saving measures (the “Restructuring”). The Company expects to substantially complete the workforce reduction by the end of the third quarter of 2022. The Company expects to record a charge in the range of $7 million to $10 million in the third quarter of 2022 as a result of the workforce reduction, consisting of one-time termination benefits for employee severance, benefits and related costs, all of which are expected to result in cash expenditures and substantially all of which will be paid out over the next five months. The Company also expects to realize run-rate savings of approximately $25 million on an annualized basis. The Company may also implement other cost savings measures as part of the Restructuring and may incur termination and other costs in connection with such measures, which could be material. As part of the Restructuring, the Company is also reviewing its alternatives with respect to additional facility space that it currently leases in Bedford, Massachusetts. These alternatives may include the termination of the lease or the sub-lease of all or a portion of the leased facility. The Company is currently unable to estimate facility-related charges, which could be material.

The Company’s estimates are based on a number of assumptions. Actual results may differ materially, and additional charges not currently expected may be incurred in connection with, or as a result of, the Restructuring. As permitted by Item 2.05 of Form 8-K, the Company will file an amendment to this report if charges and future cash payments differ materially from current estimates.

The information in this Item 2.05 as well as the section in the Earnings Release entitled “Strategic Business Re-Alignment Plan” shall be deemed “filed” for purposes of Section 18 of the Exchange Act.
