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 measures of Non-GAAP Gross Profit, Non-GAAP Gross Margin and Adjusted EBITDA are useful in evaluating its operating performance. Ouster calculates Non-GAAP Gross Profit as gross profit (loss) excluding amortization of acquired intangibles, certain excess and obsolete expenses and losses on firm purchase commitments, and stock-based compensation expense. Non-GAAP Gross Margin is calculated as Non-GAAP Gross Profit divided by revenues. Adjusted EBITDA is calculated as net loss excluding interest expense (income), net, other (income) expense, net, stock-based compensation expense, provision for (benefit from) income taxes, certain excess and obsolete expenses and loss on firm purchase commitments, amortization of acquired intangibles, depreciation expense, certain litigation expenses, gain on lease termination and other items. Ouster believes that Non-GAAP Gross Profit, Non-GAAP Gross Margin, and 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. Adjusted EBITDA is also used by the Board and management as a performance metric for compensation purposes. 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.
