Rapid Micro Biosystems intends to use the Investor Relations page of its website as a means of disclosing material nonpublic information and for complying with its disclosure obligations under Regulation FD. Accordingly, investors should monitor its website in addition to following press releases, filings with the Securities and Exchange Commission ( “SEC”), public conference calls, presentations and webcasts. Non-GAAP Financial Measures In addition to reporting financial measures in accordance with generally accepted accounting principles ( “GAAP”), the Company is including in this press release "non-GAAP adjusted EBITDA," which is a non-GAAP financial measure. The Company defines non-GAAP adjusted EBITDA as net loss excluding interest income, interest expense, other expense, net, income tax expense, depreciation and amortization, and stock- based compensation. The Company includes this non-GAAP financial measure because it believes it allows investors to understand and evaluate the Company’s core operating performance and trends. In particular, the exclusion of certain items in calculating non-GAAP adjusted EBITDA can provide useful measures for period-to-period comparisons of the Company’s core business. This non-GAAP financial measure has limitations as an analytical tool, including the fact that such non-GAAP financial measure may not be comparable to a similarly titled measure presented by other companies because other companies may calculate non-GAAP EBITDA differently than the Company does. For more information regarding this non-GAAP financial measure, see the table included at the end of this press release.
