AOS Chairman and Chief Executive Officer Dr. Mike Chang commented, "Our fiscal Q4 was another strong quarter despite the challenge posed by the COVID lockdown in Shanghai. Once again, we outperformed our guidance midpoint. Revenue was $194 million, an increase of 9% year-over-year. Non-GAAP gross margin was 33.8% and non-GAAP EPS was $0.95. As a reminder, our ability to assemble and ship products was severely limited for most of April due to the city-wide lockdown in Shanghai. Once cleared to restart operations at the end of April, it also took time for our assembly lines to return to full utilization. Our Shanghai facilities are mostly back to normal and are currently operating at full capacity. I want to express my deepest appreciation to our employees once again for their immense sacrifice and unwavering dedication to AOS during these challenging times. We are grateful to have their loyalty and support.”

Dr. Chang continued, "Looking ahead, we are seeing inventory corrections happening in certain consumer end markets. While we are not immune to current global market conditions, as of today, our demand and backlog are still higher than our overall capacity. I believe our strategic position within our sector is resilient thanks to our technology leadership, diversified product portfolio, and strong Tier 1 customer base in all our business segments. In fact, our market share at Tier 1 customers is the highest that it has ever been. The electrification of everything is just getting started, and our power products sit at the forefront of this trend. We are on pace and focused to achieve our one billion dollar annual revenue target in the next couple of years.”

Forward Looking Statements

This press release contains forward-looking statements that are based on current expectations, estimates, forecasts and projections of future performance based on management's judgment, beliefs, current trends, and anticipated product performance.

Forward-looking statements involve risks and uncertainties that may cause actual results to differ materially from those contained in the forward-looking statements. These factors include, but are not limited to, the impact of COVID-19 pandemic on our business and the city-wide lockdown in Shanghai; deconsolidation of CQJV; our lack of control over the joint venture in China; difficulties and challenges in executing our diversification strategy into different market segments; new tariffs on goods from China; ordering pattern from distributors and seasonality; changes in regulatory environment and government investigation; our ability to introduce or develop new and enhanced products that achieve market acceptance; decline of PC markets; the actual product performance in volume production; the quality and reliability of our product, our ability to achieve design wins; the general business and economic conditions; the state of semiconductor industry and seasonality of our markets; our ability to maintain factory utilization at a desirable level; and other risks as described in our SEC filings, including our Annual Report on Form 10-K for the fiscal year ended June 30, 2022 to be filed by AOS with the SEC and other periodic reports we filed with the SEC. Other unknown or unpredictable factors or underlying assumptions subsequently proving to be incorrect could cause actual results to differ materially from those in the forward-looking statements. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, level of activity, performance, or achievements. You should not place undue reliance on these forward-looking statements. All information provided in this press release is as of today's date, unless otherwise stated, and AOS undertakes no duty to update such information, except as required under applicable law.

Use of Non-GAAP Financial Measures

To supplement our unaudited consolidated financial statements presented on a basis consistent with U.S. GAAP, we disclose certain non-GAAP financial measures for our historical performance, including non-GAAP gross profit, gross margin, operating income, net income attributable to AOS, net income, diluted earnings per share ("EPS") and EBITDAS. These supplemental measures exclude, among other items, share-based compensation expenses, legal costs related to government investigation, amortization of purchased intangible, production ramp up costs related to the JV Company, income tax effect of non-GAAP adjustments, equity method investment loss from equity investee, and gain on deconsolidation and changes of equity interest in the JV Company. We also disclose certain non-GAAP financial measures in our guidance for the next quarter, including non-GAAP gross margin, operating expenses and earnings/loss in equity method investment. We believe that these historical and forecast non-GAAP financial measures provide useful information to both management and investors by excluding certain items and expenses that are not indicative of our core operating results or do not reflect our normal business operations. In addition, our management uses non-GAAP measures to compare our performance relative to forecasts and to benchmark our performance externally against competitors. Our use of non-GAAP financial measures has certain limitations in that such non-GAAP financial measures may not be directly comparable to those reported by other companies. For example, the terms used in this press release, such as non-GAAP net income (loss) or non-GAAP operating expenses, do not have a standardized meaning. Other companies may use the same or similarly named measures, but exclude different items, which may not provide investors with a comparable view of our performance in relation to other companies. In addition, we included the income tax effect of non-GAAP adjustments in the non-GAAP net income of reconciliation table for all periods presented as the management believes that such non-GAAP presentation provides useful information to investors, even though the amounts are not significant. We seek to compensate for the limitation of our non-GAAP presentation by having provided a detailed reconciliation of the non-GAAP financial measures to the most directly comparable U.S. GAAP measures both in the text in this press release and in the tables attached hereto. Investors are encouraged to review the related U.S. GAAP financial measures and the reconciliation of these non-GAAP financial measures to their most directly comparable U.S. GAAP financial measures.
