AOI Q2 2026 Earnings: Revenue Rises 86% as Non-GAAP Profit Returns

Applied Optoelectronics (NASDAQ: AAOI) reported Q2 2026 revenue of $191.9 million, up 86.4% year over year, while GAAP diluted loss widened to $0.28 per share from $0.16. Non-GAAP net income reached $5.5 million, or $0.06 per diluted share, as datacenter and CATV revenue increased and 800G product volume more than doubled sequentially. GAAP gross margin nevertheless declined to 27.7%, and the company remained unprofitable on both a GAAP operating basis and an adjusted EBITDA basis.

Core financial results

Revenue increased by approximately $89.0 million from the prior-year quarter. Datacenter products generated most of that increase, while adoption of 1.8 GHz CATV products provided another material contribution.

Profitability was more mixed. Gross profit increased, but not as quickly as revenue, and higher operating expenses caused the GAAP operating loss to widen in dollar terms. All dollar amounts below are in millions except per-share data.

Business and segment performance

Datacenter revenue more than doubled and accounted for about 56% of total revenue. CATV remained the second-largest business and represented approximately 42% of revenue.

Datacenter contributed approximately $62.9 million, or 71%, of the company’s total year-over-year revenue increase. Management attributed the performance partly to an 800G volume ramp that more than doubled sequentially. CATV added approximately $24.6 million of growth, supported by higher-volume adoption of AOI’s 1.8 GHz products.

AOI said its total manufacturing capacity was approaching 200,000 units per month. By the end of 2026, it expects to be capable of producing around 650,000 units of 800G and 1.6 Tb products per month. Management also forecast that demand for these products would exceed production capacity through mid-2027.

Profitability and balance sheet

Total operating expenses rose 65.3% to $77.9 million, including research and development expenses of $34.9 million and general and administrative expenses of $31.6 million. Because expenses grew more slowly than revenue, the operating loss narrowed as a percentage of sales even though it widened by $8.8 million in absolute terms.

The difference between GAAP and non-GAAP profitability was substantial. The approximately $28.3 million bridge from a $22.8 million GAAP net loss to $5.5 million of non-GAAP income included a $14.3 million tax-related adjustment, $4.9 million of share-based compensation, $4.7 million of non-recurring expenses, and expenses associated with discontinued products. Adjusted EBITDA remained slightly negative at $0.5 million, indicating that the return to profitability depended on the company’s non-GAAP adjustments.

Between December 31, 2025 and June 30, 2026, cash, cash equivalents, and restricted cash increased from $216.0 million to $508.8 million. Over the same period, inventories rose from $183.1 million to $278.8 million, accounts receivable increased from $244.4 million to $314.0 million, and net property, plant, and equipment climbed from $376.1 million to $697.1 million amid the production expansion.

The weighted-average basic share count also increased to 81.6 million from 56.8 million a year earlier, a rise of approximately 43.7%. This reduced the amount of earnings or increased the amount of loss attributable to each share relative to a stable share-count scenario.

Q3 2026 guidance

AOI expects another substantial sequential revenue increase in Q3. The $272.5 million midpoint of its revenue range would represent approximately 42% growth from Q2, although the midpoint of the non-GAAP gross-margin range is roughly unchanged from Q2’s 29.8%.

The outlook implies that higher production volume should lift revenue and non-GAAP income, but it does not assume a clear near-term expansion in gross margin. Execution of the planned 800G and 1.6 Tb capacity ramp will therefore be central to reaching the guidance.

Recent insider transactions

The 10 most recent records supplied contain nine sales and one stock award. These transactions are presented objectively; reported sales or awards do not establish an insider’s motivation or view of the company’s prospects.

Separately, the supplied six-month aggregate reports 1,808,858 shares categorized as purchases and 825,813 as sales, for net purchases of 983,045 shares. Because that aggregate does not break the purchase category down into open-market purchases, awards, or exercises, it should not be interpreted on its own as evidence of insider sentiment.

Risks investors should monitor

• Capacity-ramp execution: AOI is expanding production rapidly to meet demand for 800G and 1.6 Tb products. Manufacturing delays, supply constraints, or slower qualification could limit revenue despite customer demand.
• Continued GAAP losses: Revenue growth has not yet produced GAAP profitability, while adjusted EBITDA remained slightly negative. Higher operating costs or weaker margins could prolong this gap.
• Limited margin expansion: GAAP gross margin declined 2.6 percentage points year over year, and Q3 non-GAAP margin guidance is centered near the Q2 level. Higher volumes may not immediately translate into better unit economics.
• Inventory, receivables, and capital intensity: Inventory, accounts receivable, and property and equipment all rose materially from year-end as AOI expanded. A slowdown in shipments or collections could make those investments less productive.
• Customer concentration and demand variability: AOI identifies reliance on a small number of customers, pricing pressure, order reductions, tariffs, and supply-chain disruptions as factors that could affect revenue and profitability.

Summary

AOI’s Q2 2026 results showed rapid growth led by datacenter optics and CATV products, together with a return to non-GAAP net profitability. However, lower GAAP gross margin, a wider GAAP loss, and slightly negative adjusted EBITDA show that higher sales have not yet translated into broadly based profitability. The next major test is whether AOI can execute its capacity expansion and deliver Q3’s projected revenue increase without additional margin pressure or disproportionate growth in operating costs.
