Item 1.01 Entry into a Material Definitive Agreement.

Securities Purchase Agreement

On April 2, 2025, Akoya Biosciences, Inc. (“Akoya”) entered into a securities purchase agreement (the “Securities Purchase Agreement”) with Quanterix Corporation (“Quanterix”), pursuant to which Akoya will issue and sell to Quanterix from time to time, in a private placement, one or more convertible promissory notes having an aggregate principal amount of up to $30,000,000 (the “Convertible Notes”). Akoya may draw on the Convertible Notes between May 15, 2025 and the earlier of (a) the closing of the transactions contemplated by the Agreement and Plan of Merger, dated as of January 9, 2025, as it may be amended from time to time, by and among Quanterix, Akoya and Wellfleet Merger Sub, Inc. (the “Merger Agreement”) and (b) July 9, 2025 if the Merger Agreement is lawfully terminated pursuant to its terms on or prior to such date; provided, however, that if the closing of the transaction contemplated by the Merger Agreement occurs on or prior to May 15, 2025, Akoya may not draw the Convertible Notes. Additionally, if the initial termination date of July 9, 2025 is extended to January 9, 2026 in accordance with the terms of the Merger Agreement, Akoya may draw on the Convertible Notes until January 9, 2026.

Any Convertible Notes issued under the Securities Purchase Agreement will mature on the earliest to occur of (i) the 91^st day following the earlier of (a) November 1, 2027 and (b) the date that Akoya’s indebtedness under the Credit and Security Agreement, dated October 27, 2020, by and among Akoya, Midcap Financial Trust, as a lender and as agent (“MidCap”), and the other lenders named therein (the “Akoya Existing Loan Agreement”) is repaid in full and all commitments under such documents have been terminated and (ii) subject to the terms of the Subordination Agreement (as defined below), any acceleration of the Convertible Notes. Any Convertible Note issued under the Securities Purchase Agreement will bear interest at a rate per annum equal to the SOFR interest rate plus an applicable margin specified in the Convertible Note to, but excluding, the date of repayment or conversion of the Convertible Note. Interest on the Convertible Notes will be paid in arrears on the first day of each month and on the maturity date of the Convertible Notes. Subject to the terms of the Subordination Agreement, any interest payments will be made exclusively to Quanterix in cash.

If drawn, the Convertible Notes will be convertible at the election of Quanterix during the period beginning on the date, if any, that the Merger Agreement is terminated and ending on the maturity date of the Convertible Notes into shares of common stock, par value $0.00001, of Akoya (“Akoya Common Stock”), at a conversion price equal to the product of (i) the exchange ratio set forth in the Merger Agreement, as it may be adjusted pursuant to the terms of the Merger Agreement, and (ii) the VWAP of Quanterix’s common stock for the 10 consecutive trading days ending on the trading day prior to the entry into the Merger Agreement, subject to adjustment.

The Convertible Notes prohibit conversion if it would result in the issuance of more than 19.99% of Akoya Common Stock in the aggregate prior to obtaining stockholder approval. The Convertible Notes will also contain customary anti-dilution provisions to adjust the conversion price from time to time based upon certain issuances of securities by Akoya. The Securities Purchase Agreement contains customary representations and warranties and events of default as well as certain operating covenants applicable to Akoya until the closing of the transaction contemplated by the Merger Agreement.

Registration Rights Agreement

At such time as Akoya draws any funds and thereby issues any Convertible Notes, Akoya and Quanterix will enter into a registration rights agreement (the “Registration Rights Agreement”), pursuant to which, among other things, Akoya must prepare and file with the U.S. Securities and Exchange Commission (the “SEC”) no later than August 13, 2025 a registration statement with respect to the resale of shares of Akoya Common Stock issuable upon conversion of the Convertible Notes.

Subordination Agreement

At such time as Akoya draws any funds and thereby issues any Convertible Notes, Quanterix, Akoya and MidCap will enter into a subordination agreement (the “Subordination Agreement”), pursuant to which Quanterix and Akoya will agree, among other things, that the Convertible Notes will be subordinate to any debt outstanding and obligations owing under the Akoya Existing Loan Agreement.

Cautionary Statement Regarding Forward-Looking Statements

Statements included in this Current Report on 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 transaction contemplated by the Merger Agreement (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 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; the ability of Akoya to repay any Convertible Notes 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 Current Report 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.
