Use of Non-GAAP Financial Measures (Unaudited)

In addition to the financial results prepared in accordance with generally accepted accounting principles in the United States (GAAP), this press release contains the metric adjusted EBITDA, which is not calculated in accordance with GAAP and is a non-GAAP financial measure. Adjusted EBITDA is defined as net loss adjusted for interest income (expense), income tax expense (benefit), depreciation and amortization expense, stock-based compensation expense, and certain other non-cash, unusual or non-recurring items, including, for example, losses on extinguishment of debt and changes in the fair value of warrant liabilities; we do not exclude normal, recurring, cash operating expenses from this measure. Such items could have a significant impact on the calculation of GAAP net loss.

Exagen uses adjusted EBITDA internally because the company believes these metrics provide useful supplemental information in assessing its operating performance reported in accordance with GAAP. Exagen believes adjusted EBITDA may enhance an evaluation of our operating performance because it excludes the impact of prior decisions made about capital investment, financing, investing and certain expenses the company believes are not indicative of our ongoing performance. However, this non-GAAP financial measure may be different from non-GAAP financial measures used by other companies, even when the same or similarly titled terms are used to identify such measures, limiting their usefulness for comparative purposes.

This non-GAAP financial measure is not meant to be considered in isolation or used as a substitute for net loss reported in accordance with GAAP, should be considered in conjunction with our financial information presented in accordance with GAAP, has no standardized meaning prescribed by GAAP, is unaudited, and is not prepared under any comprehensive set of accounting rules or principles. In addition, from time to time in the future, there may be other items that Exagen may exclude for purposes of these non-GAAP financial measures, and the company may in the future cease to exclude items that it has historically excluded for purposes of these non-GAAP financial measures. Likewise, Exagen may determine to modify the nature of adjustments to arrive at these non-GAAP financial measures. Because of the non-standardized definitions of non-GAAP financial measures, the non-GAAP financial measure as used by the company in this press release and the accompanying reconciliation table have limits in their usefulness to investors and may be calculated differently from, and therefore may not be directly comparable to, similarly titled measures used by other companies. Accordingly, investors should not place undue reliance on non-GAAP financial measures.

A reconciliation of net loss to non-GAAP adjusted EBITDA is provided in the financial schedules that are part of this press release.
