“Ouster achieved strong second quarter results above the high end of guidance and shipped a record 5,500 sensors, bringing Physical AI to life across logistics, industrial, and smart infrastructure sites around the world,” said Ouster CEO Angus Pacala. “We continue to make progress against each of our top priorities: advancing the development of our product portfolio, scaling our software-attached business, and executing towards profitability. We are well positioned for continued growth as we see customers successfully moving from prototype testing and into commercial production. Our story is just getting started, and we have the team, customers, and strategy to be a leader in Physical AI.”

Revenue

Ouster delivered quarterly revenue of $35 million, an increase of 30% year over year and 7% sequentially. Demand was primarily driven by customers in the industrial and automotive verticals for use cases in warehouse automation, yard logistics, and robotaxis. The Company shipped over 5,500 sensors for revenue, a new quarterly record. The Company continues to work closely with customers to mitigate any disruptions resulting from the unpredictable geopolitical and macroeconomic environment.

Gross Margin

GAAP gross margin of 45%, an increase of 1100 basis points compared to 34% in the second quarter of 2024 and 400 basis points compared to 41% in the first quarter of 2025. Gross margin benefitted from higher revenues, product mix, and a favorable employment tax refund. Non-GAAP gross margin increased to 52%, an improvement of approximately 1200 basis points year over year and 500 basis points sequentially. Non-GAAP gross margin excludes the impact of stock-based compensation expenses and certain other items outside of ordinary operations.

¹	Adjusted EBITDA loss and non-GAAP gross margin are non-GAAP financial measures. See Non-GAAP Financial Measures for additional information and reconciliations of these measures to their respective most directly comparable financial measures calculated in accordance with U.S. GAAP.

In addition, see information below concerning non-GAAP financial measures.

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 expense (income), 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 and gain on lease termination. 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.
