Applied Optoelectronics Inc. struck an optimistic tone on its latest earnings call, leaning on record revenue, surging data center demand, and early traction in 800G and 1.6T products to justify a sizable upgrade to its 2026 outlook. Management acknowledged near-term losses, margin pressure, and execution risks, but argued that capacity expansion and strong bookings position the company for outsized growth over the next several years.
Record Revenue Marks Fourth Straight High
Applied Optoelectronics delivered first-quarter revenue of $151.1 million, setting a record for the fourth consecutive quarter and underscoring strong top-line momentum. Sales climbed 51% year over year and 13% sequentially, landing squarely within guidance of $150 million to $165 million and reinforcing investor confidence in the company’s growth trajectory.
Data Center Business Surges on High-Speed Demand
Data center revenue jumped to $81.4 million, up 154% from a year earlier and 9% sequentially, highlighting the accelerating shift to higher-speed optics. Management cited 36% year-over-year growth in 100G products and a tenfold increase in 400G sales, while 800G generated $4.6 million, as the company completed its first volume shipment of 800G transceivers and secured its inaugural volume order for 1.6T devices.
CATV Segment Delivers Solid Sequential Upside
The CATV business produced revenue of $66.8 million, up 4% year over year and a strong 24% sequentially, landing at the high end of the company’s $61 million to $67 million outlook. Management now expects second-quarter CATV revenue of $75 million to $80 million and forecasts more than $325 million in annual CATV sales, signaling durable demand in this legacy franchise.
2026 Outlook Raised Above $1.1 Billion
Management raised its 2026 forecast, now targeting revenue in excess of $1.1 billion and non-GAAP operating income above $140 million, an increase from prior expectations of roughly $1.0 billion. Executives framed the upgrade as a reflection of robust bookings, particularly from hyperscale customers, and growing visibility into demand for 800G and 1.6T products.
Ambitious Capacity Expansion to Meet Future Demand
Applied Optoelectronics is undertaking a major manufacturing build-out, expanding its Texas footprint to about 900,000 square feet across multiple facilities to support high-speed optical production. The company exited the quarter with roughly 100,000 units per month of 800G and 1.6T capacity, expects to approach 150,000 this quarter, and is targeting more than 650,000 units per month by the end of 2026 and over 930,000 by late 2027.
In-House Lasers and CPO Strategy as Competitive Edge
A key strategic pillar is the company’s in-house laser manufacturing, which management says will underpin its move into advanced co-packaged optics, or ELSFP. Applied Optoelectronics plans to expand laser fabrication capacity by about 350% by 2027 and aims to ramp ELSFP output to around 400,000 units per month, setting a goal of becoming one of the world’s leading laser suppliers by the end of next year.
Balance Sheet Strengthens with Higher Cash Reserves
The company ended the quarter with $449.4 million in cash, cash equivalents, short-term investments and restricted cash, more than doubling from $216 million at the end of last year. Management emphasized that this enlarged cash position provides the financial flexibility needed to fund heavy capital expenditure, support inventory builds, and navigate the extended lead times associated with new manufacturing equipment.
Hyperscale Orders Underpin Growth Visibility
Applied Optoelectronics reported multiple new volume orders from large hyperscale customers, including its first 1.6T volume deal and two new 800G orders that bolster its high-speed pipeline. The company also expects one hyperscale customer to reemerge as a 10% or greater contributor to revenue, a sign that key cloud accounts are committing to long-term adoption of its optics.
Losses Persist Despite Revenue Momentum
Despite strong sales growth, the company remains in the red, posting a GAAP net loss of $14.3 million, or $0.19 per share, compared with a $9.2 million loss a year earlier. On a non-GAAP basis, the net loss widened to $4.9 million, or $0.07 per share, versus a $0.02 per share loss in the prior-year quarter, underscoring the lag between revenue growth and profitability.
Margins Under Pressure from Product Mix
Non-GAAP gross margin came in at 29.2%, matching guidance but down from 31.4% in the prior quarter and 30.7% in the year-ago period, reflecting about a 2.2 percentage-point sequential decline. Management attributed the pressure largely to product mix, as rapidly expanding data center shipments weigh on margins in the near term even as the company reiterates a long-term target near 40%.
Demand Outstrips Capacity Through Mid-2027
Executives cautioned that demand for 800G and 1.6T products is expected to exceed available capacity through at least mid-2027, effectively capping near-term revenue upside. While this capacity shortfall underscores the strength of the order book, it also introduces timing risk, as revenue realization will be gated by how quickly new lines and equipment can be qualified and ramped.
Customer Concentration Remains a Key Risk
Customer concentration remains high, with the top 10 accounts representing 98% of first-quarter revenue, slightly above last year’s 97%. Three customers accounted for more than 10% each, including a single CATV customer contributing 44% of total revenue, leaving the company exposed to contract changes or demand swings from a small set of large buyers.
Telecom Segment Weakness Highlights Volatility
Telecom revenue slipped to $2.6 million, down 13% year over year and 50% sequentially, underscoring continued softness and volatility in that segment. Management indicated that quarter-to-quarter swings are likely to persist, reinforcing the company’s strategic focus on data center and CATV markets where demand has been more consistently robust.
Inventory Build and Higher Leverage to Fund CapEx
Inventory rose to $206.2 million from $183.1 million at the end of the prior quarter, as the company builds stock to support expected demand and new product ramps. Capital expenditures totaled $68.7 million in the first quarter and are projected to run higher in coming quarters, with funding drawn from cash, operations, equity issuance, and additional borrowing that lifted non-convertible debt to $77 million.
Long Lead Times Heighten Execution Risk
Management highlighted long equipment lead times, noting that some laser tools can take 18 to 24 months or more to arrive, combined with multi-month customer qualification cycles for new capacity. These delays add execution risk to the company’s ambitious ramp plan, leaving its near-term results sensitive to any slippage in equipment deliveries or customer approvals.
Tariffs Hurt Margins Amid Uncertain Recovery
The company reported direct tariff costs of $1.4 million in the quarter, a drag on profitability as it navigates shifting trade policies. While Applied Optoelectronics has applied for a refund of at least $5.7 million, management cautioned that the process is new and the timing of potential recoveries remains uncertain.
Guidance Signals Aggressive Growth and Investment
Looking ahead, the company guided second-quarter revenue to between $180 million and $198 million, with non-GAAP gross margin of 29% to 30% and non-GAAP net results ranging from a $2.5 million loss to a $2.8 million profit. By 2026, management expects revenue to surpass $1.1 billion and non-GAAP operating income to exceed $140 million, driven by a rapid ramp in 800G and 1.6T capacity to more than 650,000 units per month by year-end and robust ELSFP and laser expansion, albeit with sustained heavy quarterly CapEx.
Applied Optoelectronics’ latest call paints a company in the middle of an aggressive, capital-intensive expansion, balancing near-term losses and execution risks against a powerful secular wave in high-speed optics. For investors, the story hinges on whether management can deliver its ambitious capacity ramp on schedule, but the upgraded guidance, strong hyperscale demand, and reinforced balance sheet suggest meaningful upside if execution stays on track.
