• GAAP operating income was $31.2 million, up from $27.7 million in the prior quarter and up from $17.8 million in the same quarter last year.

• GAAP net income per diluted share attributable to AOS was $1.11, compared to $13.54 net income per share for the prior quarter primarily due to the gain on deconsolidation and changes of equity interest in the JV Company, and $0.58 net income per share for the same quarter a year ago.

• Consolidated cash flow provided by operating activities was $61.8 million, which included $6.4 million net customer deposits, as compared to $50.8 million in the prior quarter, which included $11.2 million net customer deposits.
• The Company closed the quarter with $323.1 million of cash and cash equivalents.
• In April 2022, we became aware of a cybersecurity incident involving unauthorized access to our internal email system, which resulted in a loss of $1.5 million for the three months ended March 31, 2022.  We are conducting a comprehensive investigation of the incident.  As part of our quarterly review process and in consultation with our independent auditors, the management is currently assessing the impact of this incident on our internal control over financial reporting as of March 31, 2022.  The financial impact of this incident is not material, and we expect there will be no changes to previously released financial results or financial statements.

AOS Chairman and Chief Executive Officer Dr. Mike Chang commented, “Q3 was another great quarter and once again, we succeeded in outperforming our guidance. Our revenue grew 20% year-over-year to a record $203 million, which was the first time in our history to cross the $200 million threshold. This was achieved by securing additional wafer capacity from our existing foundry partners and continuing to optimize product mix. This resulted in a record non-GAAP EPS of $1.34, up 74% year-over-year.”

Dr. Chang continued, “For the June quarter, a good portion of our back-end packaging and testing operations were suspended for three weeks in April due to the city-wide COVID lockdown in Shanghai. Fortunately, at the end of April, the Shanghai government classified AOS as an essential business and cleared us to resume operations. However, the pace at which we can open is still uncertain. We currently estimate the Shanghai lockdown will impact the June quarter revenue by approximately $20 million to $25 million, but expect to recover a good portion of the lost revenue in the second half of the calendar year once things normalize. Looking out further, we believe the impact of the lockdown is temporary and we remain on our growth trajectory to reach $1 billion annual revenue in 2024.”

Business Outlook for Fiscal Q4 Ending June 30, 2022

The following statements are based on management's current expectations. These statements are forward-looking, and actual results may differ materially. AOS undertakes no obligation to update these statements.

Our expectations for the fourth quarter of fiscal year 2022 are as follows:

• Revenue to be approximately $190 million, plus or minus $10 million, primarily reflecting the suspension of production at our Shanghai packaging and testing facilities due to the impact of the Shanghai COVID lock down. Our Shanghai facilities had resumed partial production at the end of April. This guidance is based on the assumptions that our Shanghai facilities remain COVID free and can continue to ramp up its production gradually in May and return to normal production in June.
• GAAP gross margin to be 31.9% plus or minus 2%. We anticipate non-GAAP gross margin to be 33.0% plus or minus 2%, reflecting the estimated impact of suspension of operations and incremental expenses required in response to the Shanghai COVID shut down and gradual resumption of production. Non-GAAP gross margin guidance excludes $0.8 million amortization of acquired IP and $1.3 million of estimated share-based compensation charges.
• GAAP operating expenses to be in the range of $44.3 million plus or minus $1 million. Non-GAAP operating expenses are expected to be in the range of $36.0 million plus or minus $1 million. Non-GAAP operating expenses exclude $8.1 million of estimated share-based compensation charges and $0.2 million of estimated legal expenses relating to the government investigation.
• Interest expense is expected to be approximately $0.8 million.
• Income tax expense is expected to be in the range of $1.3 million to $1.5 million.
