Item 7.01 Regulation FD Disclosure.

On March 3, 2025, Quanterix Corporation (the “Company” or “Quanterix”) issued a press release highlighting the benefits of its proposed acquisition of Akoya Biosciences, Inc. (“Akoya”) pursuant to the terms of the Agreement and Plan of Merger (the “Merger Agreement”), by and among the Company, Wellfleet Merger Sub, Inc., a wholly owned subsidiary of the Company, and Akoya (the “Merger”). The Company also commented on a notice submitted by Kent Lake Partners nominating three candidates to stand for election to the Quanterix Board of Directors at the Company’s 2025 Annual Meeting of Shareholders. A copy of the press release is furnished as Exhibit 99.1 and is incorporated herein by reference.

The completion of the Merger remains subject to the satisfaction of customary closing conditions, including the adoption of the Merger Agreement by Akoya’s stockholders and the approval of the Company’s stockholders of the issuance of shares of common stock in connection with the Merger. The Company continues to expect the Merger to close in the second quarter of 2025, subject to the satisfaction of such conditions.

The information in this Form 8-K (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.

Important Additional Information

In connection with the Merger, Quanterix filed a Registration Statement on Form S-4 (the “Registration Statement”) which contains a preliminary joint proxy statement of Quanterix and Akoya and a preliminary prospectus of Quanterix (the “Joint Proxy Statement/Prospectus”), and each of Quanterix and Akoya may file with the SEC other relevant documents regarding the Merger. INVESTORS AND SECURITY HOLDERS ARE URGED TO READ THE REGISTRATION STATEMENT AND THE JOINT PROXY STATEMENT/PROSPECTUS CAREFULLY AND IN THEIR ENTIRETY AND ANY OTHER RELEVANT DOCUMENTS FILED WITH THE SEC BY QUANTERIX AND AKOYA, AS WELL AS ANY AMENDMENTS OR SUPPLEMENTS TO THOSE DOCUMENTS WHEN THEY BECOME AVAILABLE BECAUSE THEY WILL CONTAIN IMPORTANT INFORMATION ABOUT QUANTERIX, AKOYA AND THE MERGER. A definitive copy of the Joint Proxy Statement/Prospectus will be mailed to Quanterix and Akoya stockholders when that document is final. Investors and security holders will be able to obtain the Registration Statement and the Joint Proxy Statement/Prospectus, as well as other filings containing information about Quanterix and Akoya, free of charge from Quanterix or Akoya or from the SEC’s website when they are filed.

Participants in the Solicitation

Quanterix and Akoya and certain of their respective directors and executive officers may be deemed to be participants in the solicitation of proxies from the stockholders of Quanterix or Akoya in respect of the Merger. Information about Quanterix’s directors and executive officers is available in the Joint Proxy Statement/Prospectus, and other documents filed by Quanterix with the SEC. Information about Akoya’s directors and executive officers is available in the Joint Proxy Statement/Prospectus and Akoya’s proxy statement dated April 23, 2024, for its 2024 Annual Meeting of Stockholders, and other documents filed by Akoya with the SEC.

Investors should read the definitive Joint Proxy Statement/Prospectus carefully when it becomes available before making any voting or investment decisions. You may obtain free copies of these documents from Quanterix or Akoya as indicated above.

No Offer or Solicitation

This communication shall not constitute an offer to sell or the solicitation of an offer to buy any securities or a solicitation of any vote or approval with respect to the Merger, nor shall there be any sale of securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such

jurisdiction. No offering of securities shall be made except by means of a prospectus meeting the requirements of Section 10 of the U.S. Securities Act of 1933, as amended.

Cautionary Statement Regarding Forward-Looking Statements

Statements included in this Form 8-K which are not historical in nature or do not relate to current facts are intended to be, and are hereby identified as, forward-looking statements for purposes of the safe harbor provided by Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Forward-looking statements are based on, among other things, projections as to the anticipated benefits of the Merger as well as statements regarding the impact of the Merger on Quanterix’s and Akoya’s business and future financial and operating results, the amount and timing of synergies from the Merger and the closing date for the Merger. Words and phrases such as “may,” “approximately,” “continue,” “should,” “expects,” “projects,” “anticipates,” “is likely,” “look ahead,” “look forward,” “believes,” “will,” “intends,” “estimates,” “strategy,” “plan,” “could,” “potential,” “possible” and variations of such words and similar expressions are intended to identify such forward-looking statements. Quanterix and Akoya caution readers that forward-looking statements are subject to certain risks and uncertainties that are difficult to predict with regard to, among other things, timing, extent, likelihood and degree of occurrence, which could cause actual results to differ materially from anticipated results. Such risks and uncertainties include, among others, the following possibilities: the occurrence of any event, change or other circumstances that could give rise to the right of one or both of the parties to terminate the Merger Agreement; the outcome of any legal proceedings that may be instituted against Quanterix or Akoya; the failure to obtain necessary regulatory approvals (and the risk that such approvals may result in the imposition of conditions that could adversely affect the combined company or the expected benefits of the Merger) and stockholder approvals or to satisfy any of the other conditions to the Merger on a timely basis or at all; the possibility that the anticipated benefits and synergies of the Merger are not realized when expected or at all, including as a result of the impact of, or problems arising from, the integration of the two companies or as a result of the strength of the economy and competitive factors in the areas where Quanterix and Akoya do business; the possibility that the Merger may be more expensive to complete than anticipated; diversion of management’s attention from ongoing business operations and opportunities; potential adverse reactions or changes to business or employee relationships, including those resulting from the announcement or completion of the Merger; changes in Quanterix’s share price before the closing of the Merger; risks relating to the potential dilutive effect of shares of Quanterix common stock to be issued in the Merger; and other factors that may affect future results of Quanterix, Akoya and the combined company. Additional factors that could cause results to differ materially from those described above can be found in the Joint Proxy Statement/Prospectus, and in other documents Quanterix and Akoya file with the SEC, which are available on the SEC’s website at www.sec.gov.

All forward-looking statements, expressed or implied, included in this Form 8-K are expressly qualified in their entirety by the cautionary statements contained or referred to herein. If one or more events related to these or other risks or uncertainties materialize, or if Quanterix’s or Akoya’s underlying assumptions prove to be incorrect, actual results may differ materially from what Quanterix and Akoya anticipate. Quanterix and Akoya caution readers not to place undue reliance on any such forward-looking statements, which speak only as of the date they are made and are based on information available at that time. Neither Quanterix nor Akoya assumes any obligation to update or otherwise revise any forward-looking statements to reflect circumstances or events that occur after the date the forward-looking statements were made or to reflect the occurrence of unanticipated events except as required by federal securities laws.
