Non-GAAP Financial Measures

In addition to its results determined in accordance with generally accepted accounting principles in the United States (“GAAP”), Ouster believes the non‑GAAP measure of Adjusted EBITDA is useful in evaluating its operating performance. The calculation of Adjusted EBITDA for this reporting period does not include litigation expenses. Ouster calculates Adjusted EBITDA as net loss excluding interest expense (income), net, other expense (income), net, stock-based compensation expense, provision for income tax expense, depreciation and amortization, litigation and litigation related expenses and other non-recurring expenses. Ouster believes that Adjusted EBITDA may be helpful to investors because it provides consistency and comparability with past financial performance and may be helpful in comparison with other companies, some of which use similar non‑GAAP information to supplement their GAAP results. The non-GAAP financial information is presented for supplemental informational purposes only, and should not be considered a substitute for financial information presented in accordance with GAAP, and may be different from similarly titled non‑GAAP measures used by other companies. Reconciliation tables of the most comparable GAAP financial measures to the non-GAAP financial measures are included at the end of this press release.
