AOS Chairman and Chief Executive Officer Dr. Mike Chang commented, “While our business was negatively impacted by the industry-wide inventory correction and reduction of customer demand, we are proactively implementing measures to ensure that we emerge from this downturn stronger and more successful than ever. Even as we project a decline in our March quarter revenue, we expect to recover a good portion of the sequential decline in the June quarter, with further recovery in the 2nd half of calendar year 2023, especially with the re-opening of China.”

Dr. Chang continued, “While this temporary slowdown is disappointing, the fundamentals of our business are the strongest that they have ever been, which will enable us to meet this challenge. In 2022, we set records across almost every metric. Our annual revenue was a record $794 million and non-GAAP earnings per share was a record $4.16. These successes were driven by many critical achievements, including a significant increase in record Tier 1 customers and market share across most of our product segments.”

“AOS has been in business for over two decades and inventory corrections and market cycles are a natural and healthy part of our industry. Demand for more and better power management is being driven by what we call the ‘electrification of everything’. We believe this tailwind is here to stay despite this temporary headwind, and we are in an excellent position to continue to win and thrive in this market. We enter 2023 with many strengths: growing product offerings, promising technology roadmaps, diverse and expanding manufacturing capabilities, strong relationships with strategic customers and a robust balance sheet, which will enable us to navigate the current economic environment while keeping our eyes on achieving our one-billion-dollar annual revenue target in the next couple of years.”

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 expenses, operating income, net loss attributable to AOS, net income, diluted earnings per share ("EPS") and EBITDAS. These supplemental measures exclude, among other items, share-based compensation expenses, legal and profession fees related to government investigation, amortization of purchased intangible, income tax effect of non-GAAP adjustments, equity method investment income from equity investee, and gain on deconsolidation and changes of the 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 and operating expenses. 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 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 amount of 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 providing 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.
