TELA Bio, Inc. (the “Company”) is disclosing certain preliminary financial results for the first quarter ended March 31, 2023.

Preliminary First Quarter Results:

Preliminary unaudited operating results for the three months ended March 31, 2023 and certain preliminary financial condition information as of March 31, 2023 are as follows:

The above information is preliminary financial information as of and for the three months ended March 31, 2023 and is subject to completion. The unaudited, estimated results as of and for the three months ended March 31, 2023 are preliminary and were prepared by the Company’s management, based upon the Company’s estimates, a number of assumptions and currently available information, and are subject to revision based upon, among other things, quarter-end closing procedures and/or adjustments, the completion of the Company’s interim financial statements and other operational procedures. This preliminary financial information is the responsibility of management and has been prepared in good faith on a consistent basis with prior periods. However, the Company has not completed the Company’s financial closing procedures for the three months ended March 31, 2023, and the Company’s actual results could be materially different from this preliminary financial information, which preliminary information should not be regarded as a representation by the Company or the Company’s management as to the Company’s actual results as of and for the three months ended March 31, 2023. In addition, the Company’s independent registered public accounting firm has not audited, reviewed, compiled, or performed any procedures with respect to this preliminary financial information and does not express an opinion or any other form of assurance with respect to this preliminary financial information. During the course of the preparation of the Company’s financial statements and related notes as of and for the three months ended March 31, 2023, the Company may identify items that would require the Company to make material adjustments to this preliminary financial information. As a result, prospective investors should exercise caution in relying on this information and should not draw any inferences from this information. This preliminary financial information should not be viewed as a substitute for full financial statements prepared in accordance with United States generally accepted accounting principles and reviewed by the Company’s auditors. See “Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements.”
