Item 2.02    Results of Operations and Financial Condition.

On November 12, 2024, Quanterix Corporation (the “Company”) issued a press release announcing selected preliminary financial results for the third quarter ended September 30, 2024 and the need to restate certain previously issued financial statements as further described in Item 4.02 below (the “Press Release”). A copy of the Press Release is furnished as Exhibit 99.1 and is incorporated herein by reference.

The information contained in paragraph three (inclusive of the table) of Item 4.02(a) and in Exhibit 99.1 of this Current Report on Form 8-K is incorporated into this Item 2.02 by reference. The information incorporated by reference into this Item 2.02 is intended to be furnished under Item 2.02 and shall not be deemed “filed” under Item 2.02 for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended (the “Securities Act”), or the Exchange Act, except as expressly set forth by specific reference in such filing.

Item 4.02    Non-Reliance on Previously Issued Financial Statements or a Related Audit Report or a Completed Interim Review.

(a)On November 11, 2024, the Audit Committee of the Board of Directors of the Company, based on the recommendation of the Company’s management and after discussion with the Company’s independent registered public accounting firm, Ernst & Young LLP (“EY”), concluded that the Company’s previously issued audited consolidated financial statements as of December 31, 2023 and 2022 and for each of the three years in the period ended December 31, 2023, and its unaudited consolidated financial statements for the quarterly and year-to-date (as applicable) periods ended March 31, 2022, June 30, 2022, September 30, 2022, March 31, 2023, June 30, 2023, September 30, 2023, March 31, 2024, and June 30, 2024 (collectively, the “Non-Reliance Periods”), should no longer be relied upon.

As previously reported and as discussed in more detail below, the Company has identified and continues its efforts to remediate material weaknesses in its internal control over financial reporting relating to, among others, the operating effectiveness of internal control associated with the accounting for inventory valuation. In connection with these remediation efforts, and while performing closing procedures for the third quarter of 2024, management identified an error related to the capitalization of labor and overhead costs applied to prior periods going back to at least 2021, which impacted the valuation of inventory. This error relates to a design deficiency in the Company’s internal control over financial reporting related to the accounting for inventory valuation. The cumulative effect of this error, when taken together with unrelated immaterial errors identified by the Company in prior periods, resulted in the need for material adjustments to previously issued financial statements. The Audit Committee therefore concluded that it is appropriate to restate the financial statements included in the applicable Quarterly Reports on Form 10-Q and Annual Report on Form 10-K filed with the Securities and Exchange Commission (the “SEC”) for the Non-Reliance Periods (the “Restatement”) in order to correct all known errors in accounting.

The Company currently estimates that the corrections to be made as part of the Restatement will result in the following impacts to gross profit and operating loss:

			GAAP Gross Profit Increase						Operating Loss Increase/(Decrease)
Year ended December 31, 2021			$1.6 million						$(0.6) million
Year ended December 31, 2022			$0.4 million						$0.5 million
Year ended December 31, 2023			$2.1 million						$(2.3) million

These preliminary figures are based on currently available information and are unaudited and subject to adjustment. The supplemental schedules included in the Press Release provide additional information regarding the preliminary anticipated impact of the Restatement, but the information in the supplemental schedules is similarly based on currently available information and is unaudited and subject to adjustment. The Company does not expect the errors to result in any material impact on the previously reported amounts for cash or total revenues in any completed fiscal period.

The Restatement is not anticipated to have a material impact on the Company’s revenue growth or cash usage. However, the Company’s internal review is ongoing and there can be no assurance that the actual effects of the Restatement will be only as described above and in the supplemental schedules.

As previously disclosed in the section titled “Part II, Item 9A. Controls and Procedures” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, management concluded that the Company’s internal control over financial reporting was not effective at a reasonable assurance level as of December 31, 2023 due to, among other things, deficiencies in the operating effectiveness of its internal controls associated with the valuation of the Company’s inventory, including excess and obsolescence reserves. Management has been actively engaged in the implementation of remediation efforts to address the previously identified material weaknesses. For further discussion of management’s remediation plan, refer to the section titled “Part II, Item 9A. Controls and Procedures” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, as well as updated discussions in the section titled “Part I, Item 4. Controls and Procedures” of the Company’s Quarterly Reports on Form 10-Q for the quarters ended March 31, 2024 and June 30, 2024.

The Company intends to promptly amend (i) its Annual Report on Form 10-K for the year ended December 31, 2023, filed with the SEC on February 29, 2024 (the “Original Form 10-K”), which amended report will include summarized restated financial information for each of the quarterly periods in 2022 and 2023, and (ii) its Quarterly Reports on Form 10-Q filed with the SEC on each of May 8, 2024 and August 8, 2024 (the “Original Form 10-Qs”), which will include restated financial statements for the corresponding 2023 quarterly and year-to-date periods. In those amended reports, the Company will also revise the Management’s Discussion and Analysis of Financial Condition and Results of Operations sections to reflect the restated financial statements covered by such reports, as necessary. The Company intends to file its Quarterly Report on Form 10-Q for the quarter ended September 30, 2024, which will include restated financial statements for the quarter and year-to-date period ended September 30, 2023, as promptly as possible following the filing of the amended Original Form 10-K and the amended Original Form 10-Qs.

The Audit Committee and Company management have discussed with EY the matters disclosed in this Item 4.02(a).
