Applied Optoelectronics (NASDAQ: AAOI), or AOI, reported Q2 2026 revenue of $191.9 million, up 86.4% from $103.0 million a year earlier, while GAAP diluted EPS was a loss of $0.28 versus a $0.16 loss. Datacenter and CATV products drove nearly all the growth, helping non-GAAP EPS turn positive at $0.06. However, lower gross margin and higher operating expenses caused the GAAP net loss to widen.

Core Financial Results

Revenue increased 27.0% sequentially from $151.1 million, and management described Q2 as AOI’s fifth consecutive quarter of record revenue. Gross profit also increased, but it grew more slowly than revenue as GAAP gross margin declined to 27.7%.

AOI returned to non-GAAP net profitability, but adjusted EBITDA remained slightly negative and the GAAP net loss more than doubled. The distinction between reported and adjusted results is therefore important when assessing the quarter.

Business and Segment Performance

Datacenter revenue accounted for approximately 71% of AOI’s total year-over-year revenue increase. Management attributed the expansion to demand for high-speed optics and said 800G product volume more than doubled sequentially.

CATV supplied most of the remaining growth, supported by higher-volume adoption of AOI’s 1.8 GHz products. Together, datacenter and CATV generated more than 98% of the company’s incremental revenue.

Datacenter became AOI’s largest business at 56% of quarterly revenue, while CATV represented approximately 42%. Telecom grew from a small base and remained immaterial to the consolidated result.

Gross Profit Growth Could Not Absorb the Expense Increase

AOI generated approximately $22.0 million more GAAP gross profit than a year earlier, but total operating expenses increased by $30.8 million. Research and development expense rose by $14.3 million, general and administrative expense increased by $13.2 million, and sales and marketing expense rose by $3.4 million. As a result, the operating loss widened in dollars even though operating loss margin improved because revenue grew faster than operating expenses.

Other income also declined to $3.2 million from $6.9 million, while AOI recorded $1.3 million of income tax expense compared with none a year earlier. These factors contributed to the larger GAAP net loss.

The margin picture differed considerably by accounting basis. Non-GAAP gross margin was 29.8%, down only 60 basis points year over year and up 60 basis points sequentially. The reconciliation included $3.6 million of expenses associated with discontinued products in Q2 2026, which contributed to the wider gap between GAAP and non-GAAP gross margin.

The $28.3 million bridge from a $22.8 million GAAP net loss to $5.5 million of non-GAAP net income included a $14.3 million tax-related adjustment, $4.9 million of stock-based compensation, $4.7 million of non-recurring expenses, and costs associated with discontinued products. Adjusted EBITDA remained negative at $0.5 million, showing that the reported return to non-GAAP net income did not yet coincide with positive adjusted EBITDA.

Balance Sheet and Capacity Expansion

AOI’s balance sheet expanded materially between December 31, 2025 and June 30, 2026. Cash, inventory, receivables, property and equipment, and accounts payable all increased as the company pursued its production ramp.

Convertible senior notes were nearly unchanged at $129.1 million. The increases in inventory and receivables show that revenue growth is being accompanied by a larger operating asset base, while the rise in property and equipment reflects the broader expansion of AOI’s manufacturing footprint.

Management said total manufacturing capacity was approaching 200,000 units per month. AOI expects to be capable of producing around 650,000 units of 800G and 1.6 Tb products per month by the end of 2026. Management also forecast that demand would exceed production capacity through mid-2027, making execution of the capacity ramp central to the company’s near-term growth plan.

Q3 2026 Guidance

AOI expects another substantial sequential revenue increase in Q3. The revenue range implies growth of approximately 33% to 51% from Q2, while the non-GAAP gross-margin range surrounds the latest quarter’s 29.8% result.

The EPS outlook uses approximately 92.8 million shares. AOI did not provide a forward reconciliation of these non-GAAP measures because the relevant GAAP adjustments were not considered reasonably predictable.

Recent Insider Transactions

The supplied insider data reported 1,818,109 shares purchased across 17 transactions and 830,528 shares sold across 34 transactions during the preceding six months, for net purchases of 987,581 shares. Total insider holdings were listed at 8.29 million shares. The latest individual records were primarily direct sales, alongside one zero-price stock award; these entries are presented without inferring insiders’ views about the company.

Risks Investors Need to Watch

• GAAP profitability remains unresolved. Revenue nearly doubled, but the GAAP operating and net losses widened as the increase in gross profit did not cover higher operating expenses.
• Margin pressure could limit operating leverage. GAAP gross margin fell 260 basis points year over year, and the Q3 non-GAAP guidance allows for a result below Q2’s level.
• The capacity ramp carries execution risk. Management expects demand to exceed production capacity through mid-2027, so delays in bringing 800G and 1.6 Tb capacity online could constrain shipments and revenue growth.
• Working-capital requirements are expanding. Inventory, receivables, and accounts payable all increased materially during the first half of 2026, raising the importance of inventory management, shipments, and customer collections.

Summary

AOI’s Q2 2026 results showed rapid datacenter and CATV growth, a fifth consecutive quarterly revenue record, and a return to non-GAAP net income. At the same time, gross-margin compression and higher operating expenses widened the GAAP loss, while adjusted EBITDA remained slightly negative. The next quarter will test whether AOI can execute its planned capacity expansion, deliver the significant sequential growth embedded in guidance, and begin translating higher volume into more consistent reported profitability.
