During the second quarter of 2026, the Company completed the integration activities related to its acquisition of Akoya, including the consolidation of operational processes and financial reporting systems. As a result, management concluded that the consolidated Company constituted a single reporting unit as of June 30, 2026.

At June 30, 2026, the Company assessed events and circumstances, including declines in the Company's revenue, and concluded it was more likely than not that the fair value of its single reporting unit was less than its carrying value. As a result, the Company performed a quantitative impairment test. The Company estimated the implied fair value of its reporting unit using a market valuation approach with Level 1 inputs including the Company's quoted stock price and Level 2 inputs including certain published or readily available industry benchmark data. Based on this quantitative test, the Company determined the carrying value of its reporting unit exceeded its fair value. As a result, the Company recorded a goodwill impairment charge of $26.9 million during the three months ended June 30, 2026.

During the three months ended June 30, 2026, the Company completed the integration of Akoya's operations and reassessed its asset groups. Based on updates to how management will deploy and recover the costs of its assets, the Company determined that the assets acquired in the Akoya acquisition were combined with the legacy Quanterix assets into a single asset group for the purposes of assessing recoverability. There were no other material changes to the Company's asset groups.

Prior to performing its interim goodwill impairment test at June 30, 2026, the Company tested the recoverability of its intangible and long-lived assets. The Company utilized an undiscounted cash flow analysis to determine if the cash flows expected to be generated by each of its asset groups over the remaining estimated useful lives of each groups' primary asset were sufficient to recover the carrying value of each asset group. For certain asset groups, the analysis included an estimate of the group's disposal value. Significant assumptions that form the basis of the forecasted results utilized to calculate undiscounted cash flows include projected revenues and expenses and market conditions related to these assets. Collectively, these assumptions and estimates are based on a complex series of judgments about future events and rely heavily on estimates and assumptions that have been deemed reasonable by the Company. Changes in the estimates or assumptions used could materially affect the determination of recoverability. Potential events and circumstances that could have an adverse impact on the Company's estimates and assumptions include, but are not limited to, lower than expected revenue growth, increases in costs, and other macroeconomic factors.

At June 30, 2026, the Company concluded that no additional intangible and long-lived assets were impaired. Should economic conditions deteriorate or remain depressed for a prolonged period of time, estimates of future cash flows for each of the Company’s asset groups may be insufficient to support their carrying value, requiring an impairment. Impairment charges, if any, may be material to the results of operations and financial position.
