Item 2.01 Completion of Acquisition or Disposal of Assets.
On July 8, 2025 (the “Closing Date”), Quanterix Corporation, a Delaware corporation (the “Company” or “Quanterix”), completed the transactions contemplated by the Amended and Restated Agreement and Plan of Merger dated as of April 28, 2025 (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”). On the Closing Date, Merger Sub merged with and into Akoya (the “Merger”), with Akoya surviving the Merger as a wholly owned subsidiary of the Company. The Merger was described in the Registration Statement on Form S-4 (File No. 333- 284932) filed with the U.S. Securities and Exchange Commission (the “SEC”) on February 14, 2025, as amended by Post-Effective Amendments Nos. 1 and 2, filed on May 21, 2025 and June 6, 2025, respectively, and declared effective by the Commission on June 12, 2025 (as amended, the “Registration Statement”).
Pursuant to 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 outstanding immediately prior to the Effective Time (other than (x) 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 and (y) shares as to which a holder properly demanded appraisal and did not withdraw or lose such claim for appraisal) was converted into the right to receive the following consideration, which may be adjusted as described below: (a) 0.1461 of a fully paid and nonassessable share of common stock, par value $0.001 per share, of the Company (the shares so delivered in respect of each share of Akoya common stock, the “Per Share Stock Consideration”) and, if applicable, cash in lieu of fractional shares, subject to any applicable withholding and (b) $0.38 in cash, without interest (the “Per Share Cash Consideration”). Each of the Per Share Stock Consideration and the Per Share Cash Consideration may be adjusted up or down from $0.1461 and $0.38, respectively, pursuant to the provisions of the Merger Agreement that require an adjustment to such components in order to ensure that (i) the aggregate number of shares of common stock issued by the Company in connection with the transactions contemplated in the Merger Agreement does not exceed 19.99% of the issued and outstanding shares of common stock of the Company immediately prior to the Effective Time and (ii) the aggregate Per Share Cash Consideration paid by the Company in connection with the transactions contemplated in the Merger Agreement does not exceed $20,000,000.
The foregoing summary of the Merger Agreement and the Merger is not complete and is qualified in its entirety by reference to the complete text of the Merger Agreement, which is attached as Exhibit 2.1 hereto and is incorporated herein by reference.
Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.
Departure of Directors
Pursuant to the terms of the Merger Agreement, on July 7, 2025, Sarah Hlavinka and Martin Madaus, Ph.D. notified the Company that they were resigning from the board of directors of Quanterix (the “Board”) and each committee of the Board on which they served, effective as of immediately prior to the Effective Time. Dr. Madaus had previously informed the Board on March 27, 2025 of his intention to resign from the Board no later than the date of the Company’s 2025 annual meeting of stockholders. The circumstances giving rise to Ms. Hlavinka’s and Dr. Madaus’s resignations are not the result of any disagreement with the Company on any subject, including its operations, policies or practices.
Appointment of New Directors
Pursuant to the terms of the Merger Agreement, immediately prior to the Effective Time, Akoya designated, and the Board appointed, each of Scott Mendel and Myla Lai-Goldman, MD (together, the “Akoya Board Designees”) to fill the two vacancies on the Board created by the resignations of Ms. Hlavinka and Dr. Madaus. Mr. Mendel was appointed to Class I, with a term expiring at the annual meeting of Quanterix to be held in 2027, and Dr. Lai-Goldman was appointed to Class II, with a term expiring at the annual meeting of Quanterix to be held in 2025, each to hold such office until their successor is elected and qualified or until their earlier resignation or removal. The Board will continue to have nine directors following the Closing Date.
In accordance with the Quanterix amended and restated non-employee director compensation policy (the “Policy”), each of the Akoya Board Designees will receive an equity award valued at $400,000 comprised of (i) 60% non-qualified stock options to purchase the Company’s common stock at an exercise price equal to the closing price of the common stock on July 8, 2025 and (ii) 40% restricted stock units (“RSUs”). The options vest over three years from the date of grant, with one-third vesting on the first anniversary and the remainder vesting over the following two years in 24
successive equal monthly installments. The RSUs vest over a three-year period, with one-third vesting on each of the first, second, and third anniversaries of the grant date. Each of the Akoya Board Designees will also receive annual compensation and annual equity awards as further provided in the Policy, which is filed as Exhibit 10.12 to the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, and is incorporated herein by reference.
The Akoya Board Designees were each appointed to the Board pursuant to the terms of the Merger Agreement, which required that two directors of Quanterix resign immediately prior to the Effective Time and entitled Akoya to designate two directors to be appointed to fill the vacancies. Except as otherwise set forth herein, neither Akoya Board Designee has a direct or indirect material interest in any existing or currently proposed transaction that would require disclosure under Item 404(a) of Regulation S-K, and there is no arrangement or understanding between either Akoya Board Designee and any other person pursuant to which they were selected as directors.
