Fee computed on table in exhibit required by Item 25(b) per Exchange Act Rules 14a- 6(i)(1) and 0-11 The following material was included in a Current Report on Form 8-K filed by the Registrant substantially concurrently herewith: Quanterix Corporation (the “Company” or “Quanterix”) convened its 2025 Annual Meeting of Stockholders (the “Annual Meeting”) at 9:00am ET on September 23, 2025 (the “Original Meeting Time”). The Company adjourned the Annual Meeting without the transaction of any business. The reconvened Annual Meeting will be held on Monday, September 29, 2025 at 10:00am ET. As described above, the Company’s Annual Meeting was convened and adjourned, without any business being conducted. The meeting was adjourned to allow additional time for the Company’s stockholders to consider and vote on the proposals set forth in the Company’s definitive proxy statement filed with the US Securities and Exchange Commission (the “SEC”) on August 25, 2025 (the “Proxy Statement”). The Company has received strong support for each of the proposals. However, the proposals seeking stockholder approval to amend the Company’s Charter to eliminate the supermajority stockholder voting requirements to amend certain provisions of the Company’s Charter and to permit stockholders to amend the Company’s Bylaws (Proposals 5 and 6 in the Proxy Statement) had not yet achieved the required affirmative vote of at least 75% of the Company’s outstanding voting power at the Original Meeting Time. The Annual Meeting will reconvene at 10:00am ET on Monday, September 29, 2025, in virtual format at www.cesonlineservices.com/qtrxam_vm . Stockholders who wish to attend the adjourned meeting must pre-register at www.cesonlineservices.com/qtrxam_vm by 10:00am ET on September 28, 2025. During the adjournment, the Company will continue to solicit votes from its stockholders with respect to the proposals set forth in the Proxy Statement. The Company’s Board of Directors unanimously recommends that stockholders of record at the close of business on July 31, 2025, vote FOR the proposals identified in the Company’s Proxy Statement, including the two proposals to eliminate the supermajority vote requirements. At the Original Meeting Time, 99% of shares voted had voted FOR those two proposals, but those shares represented only 74.8% of the Company’s common stock outstanding. Proxies previously submitted in respect of the Annual Meeting will be voted at the adjourned Annual Meeting unless properly revoked, and stockholders who have previously submitted a proxy or otherwise voted do not need to take any action. The Company encourages all stockholders of record on July 31, 2025, who have not yet voted to vote by September 28, 2025, at 11:59pm ET. Stockholders who have any questions or require any assistance with completing a proxy or voting instruction form or who do not have the required materials may contact Sodali & Co., toll-free, (800) 662-5200, or by email, qtrx@info.sodali.com . If the number of additional shares of common stock voted at the adjourned Annual Meeting is not sufficient to approve the amendments to eliminate supermajority voting requirements, the Company may adjourn the Annual Meeting again.
