AOS Chief Executive Officer Stephen Chang commented, “Our fiscal Q1 results were in-line with our revenue and EPS guidance driven by sequential growth in each of our major segments. We saw seasonal strength from smartphones, computing, tablets, gaming, and wearables."

Mr. Chang concluded, “Looking into the rest of calendar year 2024, we anticipate a typical seasonal decline in notebooks and smartphones that will lead to a sequential decrease in December quarter revenue. However, we expect slight sequential growth in our Computing and Industrial segments—driven by strength in desktops, graphics cards, and quick chargers—to help partially offset this decline. Looking into next year, although visibility is limited, our strategic transition from a component supplier to a total solutions provider with a diverse product portfolio and premier customer base positions us well to outperform the broader markets we serve."

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 (loss), net income (loss), diluted earnings per share (“EPS”) and EBITDAS. These supplemental measures exclude, among other items, share-based compensation expenses, legal and professional fees related to government investigation, amortization of purchased intangible, income tax effect of non-GAAP adjustments and equity method investment loss from equity investee. 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 (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 amount of income tax effect of non-GAAP adjustments in the non-GAAP net income (loss) 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.
