Non-GAAP Financial Measures

This presentation contains non-GAAP financial measures: Adjusted EBITDA and Adjusted EBITDA margin. In addition to our results determined in accordance with GAAP, we believe that Adjusted EBITDA and Adjusted EBITDA margin, non-GAAP measures, are useful in evaluating our operating performance. We use Adjusted EBITDA and Adjusted EBITDA margin to evaluate and assess our operating performance and the operating leverage in our business, and for internal planning and forecasting purposes. We believe that Adjusted EBITDA and Adjusted EBITDA margin, when taken collectively with our GAAP results, may be helpful to investors because it provides consistency and comparability with past financial performance and assists in comparisons with other companies, some of which use similar non-GAAP financial information to supplement their GAAP results. Adjusted EBITDA and Adjusted EBITDA margin is presented for supplemental informational purposes only, should not be considered a substitute for financial information presented in accordance with GAAP and may be different from a similarly-titled non-GAAP measure used by other companies.

A reconciliation is provided below for Adjusted EBITDA to net loss, the most directly comparable financial measure stated in accordance with GAAP. We calculate Adjusted EBITDA as net loss adjusted to exclude, where applicable in a given period, depreciation and amortization, stock-based compensation expense, acquisition, offering and other expenses, interest expense, change in fair value of convertible preferred stock warrant liability and provision for income taxes.

Investors are encouraged to review our results determined in accordance with GAAP and the reconciliation of Adjusted EBITDA to net loss. thredUP is not providing a quantitative reconciliation of forward-looking guidance of Adjusted EBITDA to net loss because certain items are out of thredUP’s control or cannot be reasonably predicted. Historically, these items have included, but are not limited to, depreciation and amortization, stock-based compensation expense, change in fair value of convertible preferred stock warrant liability and provision for income taxes. Accordingly, a reconciliation for Adjusted EBITDA in order to calculate forward-looking Adjusted EBITDA margin is not available without unreasonable effort. However, for the first quarter of 2022 and full year 2022, depreciation and amortization is expected to be $2.9 million and $15.5 million, respectively. In addition, for the first quarter of 2022 and full year 2022, stock-based compensation expense is expected to be $4.0 million and $17.9

million, respectively. These items are uncertain, depend on various factors, and could result in projected net loss being materially less than is indicated by the currently estimated Adjusted EBITDA margin.
