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

On March 19, 2024, the Audit Committee (the “Audit Committee”) of the Board of Directors of UNITY Biotechnology, Inc. (the “Company”), after consultation with management, determined that the Company incorrectly classified its warrants (the “Warrants”) that were issued in August 2022 as equity which should have been recorded as liabilities and measured at fair value at each balance sheet date. This classification error has no impact on the Company’s previously reported cash and cash equivalents or marketable securities balances as of September 30, 2022, December 31, 2022, March 31, 2023, June 30, 2023, or September 30, 2023, and has no effect on its previously reported cash runway into the third quarter of 2025.

As part of its determination, the Audit Committee concluded that it is appropriate to correct the accounting for the Warrants in the Company’s financial statements for the year ended December 31, 2022 and the interim periods ended September 30, 2022, March 31, 2023, June 30, 2023, and September 30, 2023 (the “Non-Reliance Periods”) included in the associated Annual Report on Form 10-K and Quarterly Reports on Form 10-Q for each of the Non-Reliance Periods, filed with the Securities Exchange Commission (the “SEC”), by restating such audited and unaudited financial information because the errors in the financial statements are material to the financial statements for each of the Non-Reliance Periods. As a result, the audited and unaudited financial statements for each of the Non-Reliance Periods should no longer be relied on. The Company will disclose in its Annual Report on Form 10-K for the year ended December 31, 2023 the restated financial statements for each of the Non-Reliance Periods (“Restatements”). Similarly, any previously issued or filed reports, press releases, earnings releases, and investor presentations or other communications describing the Company’s financial restatements and other related financial information covering the Non-Reliance Periods should no longer be relied upon.

The Company is currently in the process of determining the full effect of the non-cash errors in the financial statements for each of the Non-Reliance Periods. The Company preliminarily estimates that the cumulative effect is an understatement of other income and an overstatement of the net loss of $15.5 million for the year ended December 31, 2022, and $2.3 million for the nine-month period ended September 30, 2023; however, such amounts are subject to revision as the Company finalizes its analysis. These errors have no effect on the Company’s previously reported cash and cash equivalents or marketable securities balances or cash runway.

The Company is currently working to complete the filing of its Annual Report on Form 10-K for the year ended December 31, 2023 as soon as practicable, which will include the Restatements.

Management is assessing the effect of these Restatements on the Company’s internal control over financial reporting and its disclosure controls and procedures. The Company expects to report at least one material weakness following completion of its analysis of the cause of these Restatements. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of a company’s annual or interim financial statements will not be prevented or detected on a timely basis. The existence of one or more material weaknesses precludes a conclusion by management that the Company’s disclosure controls and procedures and internal control over financial reporting are effective. As a result of the material weakness or material weaknesses, the Company believes that its internal control over financial reporting was not effective, and its disclosure controls and procedures were not effective for the Non-Reliance Periods.

The Company’s management and the Audit Committee have discussed the matters described in this Item 4.02 with its independent registered public accounting firm, Ernst & Young LLP.
