Ambarella, Inc. Announces Third Quarter Fiscal Year 2025 Financial Results

November 26, 2024 —Santa Clara, Calif. – Ambarella, Inc. (NASDAQ: AMBA), an edge AI semiconductor company, today announced financial results for its third quarter of fiscal year 2025 ended October 31, 2024.

Financial results on a non-GAAP basis for the third quarter of fiscal 2025 are as follows:

Based on information available as of today, Ambarella is offering the following guidance for the fourth quarter of fiscal year 2025, ending January 31, 2025:

Ambarella reports gross margin, net income (loss) and earnings (losses) per share in accordance with GAAP and, additionally, on a non-GAAP basis. Non-GAAP financial information excludes the impact of stock-based compensation, acquisition-related costs and restructuring expense adjusted for the associated tax impact, which includes the effect of any benefits or shortfalls recognized. Non-GAAP financial information also excludes the impact of the release of a valuation allowance on certain deferred tax assets. A reconciliation of the GAAP to non-GAAP gross margin, net income (loss) and earnings (losses) per share for the periods presented, as well as a description of the items excluded from the non-GAAP calculations, is included in the financial statements portion of this press release.

Total cash, cash equivalents and marketable debt securities on hand at the end of the third quarter of fiscal 2025 was $226.5 million, compared with $219.8 million at the end of the prior quarter and $222.3 million at the end of the same quarter a year ago.

“Company specific factors are more than offsetting broad market weakness, and we are reporting 30% sequential revenue growth in fiscal Q3, above the high-end of our guidance range, with strength led again by our customers’ new products, especially those incorporating our higher priced AI inference processors. Edge AI revenue represented about 70% of our total revenue, establishing a new record level, and this momentum is expected to enable growth in both our IoT and Auto markets in F2025 and F2026,” said Fermi Wang, President and CEO. “With the anticipated revenue growth, we intend to drive positive operating leverage and build upon our 15 consecutive fiscal years of positive free-cash-flow.”

Quarterly Conference Call

Ambarella plans to hold a conference call at 4:30 p.m. Eastern Time / 1:30 p.m. Pacific Time today with Fermi Wang, President and Chief Executive Officer, and John Young, Chief Financial Officer, to discuss the third quarter of fiscal year 2025 results. A live and archived webcast of the call will be available on Ambarella’s website at http://www.ambarella.com/ for up to 30 days after the call.

Non-GAAP Financial Measures

The company has provided in this release non-GAAP financial information, including non-GAAP gross margin, net income (loss), and earnings (losses) per share, as a supplement to the condensed consolidated financial statements, which are prepared in accordance with generally accepted accounting principles (“GAAP”). Management uses these non-GAAP financial measures internally in analyzing the company’s financial results to assess operational performance and liquidity. The company believes that both management and investors benefit from referring to these non-GAAP financial measures in assessing its performance and when planning, forecasting and analyzing future periods. Further, the company believes these non-GAAP financial measures are useful to investors because they

allow for greater transparency with respect to key financial metrics that the company uses in making operating decisions and because the company believes that investors and analysts use them to help assess the health of its business and for comparison to other companies. Non-GAAP results are presented for supplemental informational purposes only for understanding the company’s operating results. The non-GAAP information should not be considered a substitute for financial information presented in accordance with GAAP, and may be different from non-GAAP measures used by other companies.

With respect to its financial results for the third quarter of fiscal year 2025, the company has provided below reconciliations of its non-GAAP financial measures to its most directly comparable GAAP financial measures. With respect to the company’s expectations for the fourth quarter of fiscal year 2025, a reconciliation of non-GAAP gross margin and non-GAAP operating expenses guidance to the closest corresponding GAAP measure is not available without unreasonable efforts on a forward-looking basis due to the high variability and low visibility with respect to the charges excluded from these non-GAAP measures. We expect the variability of the above charges to have a significant, and potentially unpredictable, impact on our future GAAP financial results.
