Non-GAAP Financial Measures

This press release contains EBITDA, which is a non-GAAP measure defined as earnings before interest income and expense, taxes, depreciation and amortization.  MaxCyte believes that EBITDA provides useful information to management and investors relating to its results of operations. The company’s management uses this non-GAAP measure to compare the company’s performance to that of prior periods for trend analyses, and for budgeting and planning purposes. The company believes that the use of EBITDA provides an additional tool for investors to use in evaluating ongoing operating results and trends and in comparing the company’s financial measures with other companies, many of which present similar non-GAAP financial measures to investors, and that it allows for greater transparency with respect to key metrics used by management in its financial and operational decision-making.

Management does not consider EBITDA in isolation or as an alternative to financial measures determined in accordance with GAAP. The principal limitation of EBITDA is that it excludes significant expenses that are required by GAAP to be recorded in the company’s financial statements. In order to compensate for these limitations, management presents EBITDA together with GAAP results. Non-GAAP measures should be considered in addition to results prepared in accordance with GAAP, but should not be considered a substitute for, or superior to, GAAP results.  A reconciliation table of net loss, the most comparable GAAP financial measure, to EBITDA is included at the end of this release. MaxCyte urges investors to review the reconciliation and not to rely on any single financial measure to evaluate the company’s business.
