Item 2.02    Results of Operations and Financial Condition.

On March 20, 2025, Adaptimmune Therapeutics plc (the “Company”) provided a business update that included an update on its cash position at December 31, 2024.

The Company’s preliminary estimated total liquidity was $151.6 million as of December 31, 2024.  Total liquidity is a non-GAAP financial measure.  The most directly comparable GAAP financial measure is cash and cash equivalents.  A reconciliation of total liquidity to the most directly comparable GAAP financial measure is set forth in Exhibit 99.1 to this Current Report on Form 8-K.

 

The preliminary estimate of total liquidity and cash and cash equivalents reflect management’s current views and may change as a result of management’s review of results and other factors, including a wide variety of significant business, economic and competitive risks and uncertainties. Such preliminary financial information is subject to the finalization of our audit for the year ended December 31, 2024 and should not be viewed as a substitute for full audited financial statements prepared in accordance with U.S. GAAP.  Our independent registered public accounting firm has not yet published its audit report for the year ending December 31, 2024 nor have they expressed any opinion or any other form of assurance on these preliminary estimated results.  The report of our independent registered public accounting firm for the year ended December 31, 2024 will be set forth in our Annual Report on Form 10-K for the year ended December 31, 2024, which the Company plans to file on March 24, 2025.

Forward-Looking Statements

This Current Report on Form 8-K contains "forward-looking statements" within the meaning of the safe harbor provisions of Section 27A of the Securities Act and Section 21E of the Securities Exchange Act of 1934, as amended. Forward-looking statements address our expected future business, financial performance, financial condition, as well as the results of operations and often contain words such as “believe,” “anticipate” “expect,” “plan,” “potential,” “will,” and similar expressions. Such statements are based only upon the Company’s current expectations. Reliance should not be placed on these forward-looking statements because they involve certain risks and uncertainties. Such risks and uncertainties could cause our actual results to differ materially from those indicated by such forward-looking statements, and include, without limitation: the success, cost and timing of our product development activities and clinical trials and our ability to successfully advance our TCR therapeutic candidates through the regulatory and commercialization processes and one-time costs of the restructuring. For a further description of the risks and uncertainties that could cause our actual results to differ materially from those expressed in these forward-looking statements, as well as risks relating to our business in general, we refer you to our Annual Report on Form 10-K filed with the Securities and Exchange Commission for the year ended December 31, 2023, our Quarterly Reports on Form 10-Q, Current Reports on Form 8-K, and other filings with the Securities and Exchange Commission. The forward-looking statements contained in this Current Report on Form 8-K speak only as of the date the statements were made and the Company does not undertake any obligation to update such forward-looking statements to reflect subsequent events or circumstances.
