Rhea-AI Summary

Quanterix Corporation is asking stockholders to vote at a virtual annual meeting at 9:00 a.m. ET on September 23, 2025. Holders of record as of July 31, 2025 may vote on six proposals, including the election of three directors (Myla Lai-Goldman, Masoud Toloue and David Walt), an advisory say-on-pay vote, ratification of KPMG LLP as auditor, and three Charter amendments to declassify the Board and remove supermajority vote requirements for certain Charter and Bylaws amendments.

The company completed the acquisition of Akoya Biosciences on July 8, 2025, which led to two Akoya directors joining Quanterix and two predecessors resigning. A Cooperation Agreement with activist holder Kent Lake was reached on August 4, 2025, which includes appointing one independent director by December 1, 2025 and seeking Board declassification. The Board recommends voting in favor of all proposals.

Filing
Rhea-AI Summary

Quanterix Corporation (QTRX) filed Post-Effective Amendment No. 3 on Form S-8 to its previously declared-effective Form S-4, completing the technical step needed to register shares that will be issued under equity awards assumed from Akoya Biosciences following the recently closed merger.

  • Shares registered: 253,181 shares of Quanterix common stock, representing the maximum issuable upon vesting of outstanding Akoya restricted stock units ("Rollover RSUs").
  • Merger exchange ratio: each Akoya share converted at closing into 0.1470 Quanterix share plus $0.37 cash.
  • Total shares previously registered: 8,357,169 on the original Form S-4, covering stock consideration to Akoya shareholders and all equity awards; today’s filing carves out only the RSU component.
  • Fees: all SEC filing fees were paid with the original Form S-4; no additional fees are due.
  • Plan coverage: the amendment relates to the Akoya Biosciences 2015 & 2021 Equity Incentive Plans, now assumed by Quanterix.
  • Rule 416(a) applicability: automatic coverage for share increases from stock splits, dividends, or similar corporate actions.

Part II of the filing reiterates standard incorporation by reference of recent Quanterix periodic reports, describes Delaware law-based indemnification provisions, and lists exhibits, including opinions from Covington & Burling LLP and auditor consents. The document is strictly administrative—no new financial results, guidance, or strategic changes are disclosed; its primary purpose is to ensure that shares underlying assumed Akoya equity awards are properly registered for issuance post-merger.
