AOSL — FY2026 Financial Report Analysis

Alpha and Omega Semiconductor (AOS) makes power chips: the MOSFETs (electronic switches) and power-management ICs that regulate electricity inside laptops, servers, phones, game consoles, appliances and power tools. In the fiscal year ended June 30, 2026, revenue slipped 2.5% to $678.9 million and the operating loss widened to $43.2 million, as weak PC, gaming and power-supply demand outweighed fast growth in AI-server parts. The reported net loss shrank from $97.0 million to $42.3 million, but that improvement comes almost entirely from a $76.8 million write-down in the prior year that did not repeat, not from the business earning more.

At a glance

• Revenue $678.9M, down 2.5%. About half of that drop is a one-off: the prior year included $13.8M of licensing revenue from a silicon carbide technology deal that ended in February 2025. Chip sales alone fell about 1%.
• Operating loss $43.2M, versus $28.4M. Gross margin fell to 22.3% from 23.1% on higher material costs and lower volumes, while R&D spending rose 10.2% to $103.9M. Running the business lost more money than a year earlier.
• Cash rose to $180.8M, but not from operations. Operations used $16.3M of cash and capital spending was $51.8M; the cash pile grew because AOS sold about 20.3% of its Chinese joint venture for $150M.

The numbers

Gross margin is the share of revenue left after the direct cost of making the chips; operating margin is what is left after also paying for R&D, sales and administration, before interest and tax. Both were lower this year.

The fourth quarter (April-June 2026) was a little better than the year as a whole: revenue of $170.4M was down 3.5% from a year earlier but up 4.0% from the March quarter, and gross margin recovered to 23.1% from 21.1% in March, which the CFO attributed to "better mix and higher utilization" (factories running fuller). The quarter's operating loss was $11.0M, versus $14.1M in March and $11.6M a year earlier.

Where revenue came from

AOS reports revenue by the kind of device its chips end up in.

• Computing (50.5% of revenue, +5.8%) was the only large segment to grow meaningfully, and the growth came from what AOS calls Advanced Computing: AI servers, workstations, cloud hardware and graphics cards. In the June quarter, Advanced Computing grew 35% from March and reached a record 31% of the Computing segment. Traditional PCs and tablets were weaker. The 10-K links that to the global memory-chip shortage: DRAM prices have risen sharply because memory makers have shifted capacity to the high-bandwidth memory used in AI systems, which pushes up the price of a laptop and depresses PC sales.
• Communication (+6.8%) grew on phones, where AOS supplies battery-protection chips. Management is ramping new products with what it calls its "Tier 1 U.S. smartphone customer" (it does not name the customer) and says premium phones that charge at higher currents carry more of its chips per device.
• Consumer (-18.9%) fell mainly because of gaming: management said the current game-console cycle "nears maturity," so chip orders for consoles are falling.
• Power Supply & Industrial (-12.2%) declined on weaker quick chargers and AC-DC power supplies, partly offset by e-mobility and by DC fans used in AI server racks.

By product, power discrete devices (individual MOSFETs) fell 2.6% to $437.8M and power ICs rose 1.7% to $233.9M. Across both, unit shipments fell 3.0% while the average selling price rose 2.0% because of the shift toward higher-value products.

What the headline numbers hide

• The smaller net loss is an accounting comparison, not a recovery. FY2025's net loss included a $76.8M impairment (a write-down of the value) of AOS's stake in its Chongqing joint venture, booked when the sale price agreed for part of that stake implied a lower value than AOS carried on its books. That charge came with a $12.5M tax benefit. On our own arithmetic, excluding both, FY2025's net loss would have been roughly $32.7M, which is smaller than FY2026's $42.3M. The operating line confirms it: the operating loss widened by $14.8M.
• The adjusted figures swung too. AOS's non-GAAP results exclude stock-based pay ($26.7M this year), the joint-venture results, impairments and some tax items. On that basis it went from $10.4M of operating income to a $16.2M operating loss, and from $0.22 of EPS to a $0.43 loss. Stock-based pay is a real cost to shareholders, so the GAAP figures are the better guide here.
• Tax went the wrong way even on a pre-tax loss. AOS paid $7.5M of income tax despite a $35.6M pre-tax loss. The joint-venture sale created about $10.5M of current tax (partly offset by a $9.9M deferred benefit), and AOS also incurred $2.6M of Chinese withholding tax tied to that investment.
• Cash conversion was poor. Operating cash flow was negative $16.3M, against $29.7M positive a year earlier. Inventory rose $11.7M and the company paid down $12.1M of supplier bills. After $51.8M of capital spending (up from $37.2M, mostly manufacturing capacity), the business used about $68M of cash before the asset sale. Inventory stood at $201.4M, about 138 days of supply in the June quarter.
• Receivables grew faster than sales. Money owed by customers rose 23% to $42.8M while revenue fell 2.5%. Days sales outstanding (how long customers take to pay) was 23 days in the June quarter versus 20 in March, still short. Most sales go through two distributors, WPG and Promate, which together made up about 72% of revenue.
• The balance sheet improved because a stake was sold. The $150M joint-venture sale (all installments received by June 30) paid for $23.1M of debt repayment and an $18.2M share buyback, and still left cash $27.7M higher. Debt fell from $26.7M to $3.6M. AOS still holds an 18.9% stake, carried at $142.7M, and the joint venture remains contractually committed to supply AOS with wafer capacity.
• The buyback did not reduce the share count. AOS bought back 941,883 shares at an average of $19.22, but stock issued to employees more than offset it: weighted average shares rose from 29.4M to 30.0M.

Takeaway: The core business lost more money in FY2026 than in FY2025, and the narrower net loss reflects a write-down that did not repeat. What did change is the revenue mix: AI-server and data-center parts are now the fastest-growing piece, and the $150M joint-venture sale gives AOS cash to keep investing while PCs and consoles stay weak.

Outlook

For the September 2026 quarter (fiscal Q1 2027), AOS guided:

• Revenue of $176M, plus or minus $10M (the midpoint is 3.3% above the June quarter)
• GAAP gross margin of 23.8% (non-GAAP 24.5%), plus or minus 1 point
• GAAP operating expenses of about $52.5M (non-GAAP $46.5M)
• Tax expense of $1.1M to $1.3M; capital spending of $15M to $17M

By segment, management expects Advanced Computing to grow more than 40% from the June quarter, with AI and server products up more than 60%, so that Advanced Computing passes 40% of Computing revenue and approaches 20% of total company revenue. Even so, it expects the overall Computing segment to be roughly flat because of PC weakness. It expects Communication to rise about 10%, Power Supply & Industrial nearly 30%, and Consumer to fall about 25%. The CEO also said Typhoon Dolphin flooding in Shanghai hit part of AOS's chip packaging operations in August and would have "a slight impact" on the September quarter.

Our read: At the guidance midpoints, gross profit of roughly $41.9M would still fall about $10.6M short of $52.5M in GAAP operating expenses (our arithmetic), so management is not forecasting a return to operating profit next quarter. The pieces to watch are whether the AI-server ramp arrives at the promised pace and whether gross margin moves toward the mid-20s as management expects from mix and "an improving pricing environment" in the second half of calendar 2026. Rising R&D and capital spending mean revenue has to grow for losses to shrink, and the cash from the joint-venture sale is a one-time source, not something the business can repeat.
