Kent Lake Issues Investor Presentation Detailing Opposition to Quanterix’s Proposed Merger with Akoya Biosciences

Believes Transaction Significantly Undervalues Quanterix

Highlights that Quanterix’s Board is Essentially Rescuing Akoya at the Direct Expense of Quanterix Shareholders

Transaction Would Introduce Unnecessary Risk and Divert Cash and Management Focus Away from Quanterix’s Alzheimer’s Diagnostics Program, a Core Growth Opportunity

Calls on Quanterix Board to Answer Pressing Questions around Valuation, Process and Governance Issues in Connection with Transaction

Urges Shareholders to Vote Against Merger with Akoya to Protect the Future Value of Their Investment

Kent Lake PR LLC (“Kent Lake”) a holder of 7.25% of the outstanding common stock of Quanterix Corporation (“Quanterix” or the “Company”) (NASDAQ: QTRX), today issued a presentation to Quanterix shareholders in connection to Kent Lake’s opposition to the Company’s proposed transaction (the “Transaction”) with Akoya Biosciences (“Akoya”) (NASDAQ: AKYA).

Kent Lake’s full presentation is available at https://kentlake.s3.us-west-1.amazonaws.com/QTRX-AKYA_KLPRVoteNoDeck.pdf.

Highlights of the presentation include:

• The Transaction is a bad deal for Quanterix shareholders – The Transaction inexplicably values Akoya nearly 5x higher than Quanterix, despite Quanterix’s superior mix, growth and market opportunity. It is essentially a bailout of Akoya. Quanterix’s shares have declined nearly 40% since the deal announcement.

• Quanterix ended up bidding against itself for Akoya – As revealed in the S-4 related to the Transaction, other motivated, strategic potential buyers of Akoya walked away due to concerns around profitability, cash burn and leverage, leaving Quanterix as the only bidder. Reading the S-4 raises serious issues about the process that led to this Transaction.

• The merger introduces unnecessary risk for Quanterix – Expected National Institute of Health funding cuts will further strain Akoya’s business, making Akoya’s balance sheet situation untenable and reinforcing Kent Lake’s belief that Akoya currently has little or no positive equity value.

• Management is entrenched and conflicted – Certain directors remain on the Quanterix Board of Directors (the “Board”) despite failing to obtain majority voting from shareholders, while others appear to have undisclosed conflicts of interest that compromise their fiduciary duty to Quanterix shareholders, such as Dr. Ivana Magovčević-Liebisch’s director position at a Company with a material interest in Akoya.

• The Transaction includes a provision where Quanterix would provide Akoya with $30 million in bridge financing absent any clear shareholder mandate – This is an egregious breach of the Board’s fiduciary duty to shareholders.

• Quanterix has significant potential as a standalone company – The Transaction will divert focus away from Quanterix’s transformational Alzheimer’s testing opportunity, which, if pursued, could unlock substantial value.

In Kent Lake’s view, the incumbent Board can no longer be trusted to represent shareholders’ best interests. That is why Kent Lake recently nominated three highly qualified, independent candidates for election to Quanterix’s Board at the 2025 Annual Meeting of Shareholders. There are clear, superior alternatives for Quanterix on a standalone basis, and Kent Lake believes that abandoning the ill-fated Transaction would allow shareholders to realize greater value creation than combining with Akoya.
