Applied Optoelectronics (AAOI.US) reported robust financial results for the second quarter of fiscal 2026, marking a significant turning point as the company returned to Non-GAAP profitability on record revenue growth. Management confirmed that demand related to AI infrastructure remains strong, but repeatedly emphasized that sales of 800G and upcoming 1.6T products are outpacing current production capacity.
Guidance for the third quarter suggests a substantial jump in both revenue and earnings. Key near-term focus areas for Applied Optoelectronics include the ramp-up speed of its new Texas facility, tight supply of critical components like DSPs and TIAs, other material sourcing challenges, and short-term pressure on its 100G business due to customer switch shortages. Overall, the company's growth narrative continues to be driven by AI data center demand, but the pace of expansion will depend on its ability to overcome capacity and supply chain bottlenecks.
Management Commentary
Dr. Thomson Lin, Founder, Chairman, President, and CEO of Applied Optoelectronics, stated, "We delivered our fifth consecutive quarter of record revenue and achieved a key milestone this quarter by returning to Non-GAAP profitability." He added, "In the near term, our revenue growth is almost entirely constrained by our production capacity and the availability of key components."
Dr. Lin highlighted the accelerating demand for next-generation products and the execution of the capacity ramp. "During the second quarter, we saw a strong production ramp for our 800G products, which grew more than 100% quarter over quarter," he said. He also noted, "Market forecasts indicate that demand will continue to exceed our production capacity through mid-2027."
Dr. Stephen Murray, Chief Financial Officer and Chief Strategy Officer, stated that the company's second-quarter execution focused on three priorities: "Scaling our next-generation data center products, diversifying our revenue base, and strengthening operational execution to improve margins and position us for long-term profitability."
Murray provided an update on the 800G and 1.6T product development. "We expect 800G product revenue to grow nearly 5x sequentially in the third quarter," he said. "At the same time, we expect to complete full customer qualification for our first 1.6T product in the coming weeks and begin shipping 1.6T products later this quarter."
Financial Results
Applied Optoelectronics reported second-quarter revenue of $191.9 million, a Non-GAAP gross margin of 29.8%, and a Non-GAAP net income of $5.5 million (Non-GAAP EPS of $0.06). The balance sheet and financing updates included a total cash balance of $508.8 million and inventory of $278.8 million.
Murray detailed the Q2 revenue breakdown: "56% of revenue came from data center products, and 42% came from CATV products." He noted that the CATV business achieved a "record CATV revenue of $80.6 million."
Regarding customer concentration, Murray stated, "We had three customers each contributing over 10% of revenue... One customer accounted for 42% of total revenue; the other two customers contributed 26% and 24% of revenue, respectively."
On costs and one-time expenses, Murray noted that Non-GAAP operating expenses were $67.6 million, "higher than expected, primarily due to increased shipping costs and higher-than-expected R&D spending." He added, "We do not expect to see additional shipping costs in the third quarter and beyond."
Murray also stated, "To date, we have raised $538.8 million through our new at-the-market equity offering program." "Total capital investment in the second quarter reached $565.5 million, including $280 million in equipment prepayments."
Outlook
Management projects third-quarter revenue between $255 million and $290 million, with Non-GAAP EPS between $0.11 and $0.26, and a Non-GAAP gross margin of 29% to 30.5%. Murray reiterated the full-year outlook: "We expect 2026 revenue to be approximately $1.1 billion." He emphasized, "This revenue level is constrained by production capacity and supply chain, not by market demand."
Dr. Lin noted that the short-term product mix will be impacted by a decline in 100G products. "The 100G business will decrease by $20 million to $25 million," he said, but stressed, "Growth is primarily coming from 800G." He described the 100G decline as a "short-term impact."
Q&A Session Highlights
When asked about the potential US ban on Chinese optical transceivers, Murray responded, "It's too early to tell," but added that Applied Optoelectronics' domestic manufacturing footprint in the US "enhances our attractiveness." Dr. Lin indicated that customers are more proactive in seeking US-based manufacturers: "Customers will be more aggressive in giving us more share... especially for American manufacturers."
Regarding the 800G production ramp, Murray stated, "If we could produce more, we could ship more right now." He noted that the company's capacity is increasing from "approximately 200,000 units per month" to "about 650,000 units per month by the end of this year."
On the previously mentioned 1.6T order delivery timeline, Murray said, "Deliveries will begin very late in the third quarter and ramp up in the fourth quarter." "The majority of these products should be delivered in the fourth quarter."
When asked about the risk of Chinese laser supply, Dr. Lin stated that the CPO laser market will require "8 to 10 times the current scale of capacity." He added, "I don't think it will have any impact because the demand scale far exceeds the current global capacity."
Regarding substrate supply constraints, Murray answered, "We have secured supply for next year." Dr. Lin stated, "The company has two European suppliers, two Japanese suppliers, and three Chinese suppliers."
On the challenges of capacity ramp and gross margin trends, Dr. Lin said, "DSPs and TIAs are the key limiting factors." As for margins, he commented, "I think it could be around 32%, 33%." He also emphasized, "1.6T is a high-margin product."
Market Sentiment Analysis
Analyst sentiment was slightly negative, focusing on supply chain bottlenecks, the ramp-up timeline, and China-related competition and regulatory risks. Management's tone was slightly positive, but they consistently emphasized capacity and supply constraints, repeatedly stating, "Short-term revenue is almost entirely limited by production capacity and key component supply," and "We absolutely do not want to overpromise." Compared to the previous quarter, management's confidence in robust market demand remains unchanged, but analysts in the Q&A session were more focused on the China market and short-term supply issues. Dr. Lin's repeated mantra of "not wanting to overpromise" was also evident in the Q&A session.
Risks and Concerns
Supply constraints remain the core issue. Dr. Lin mentioned "key component supply" and "DSPs and TIAs in 800G and 1.6T products." The company pointed out that 100G product demand is affected by customer switch supply constraints. Murray stated that one customer "cannot obtain a sufficient number of 100G switches," and this problem is "related to memory shortages."
Tariff uncertainty is also a risk factor. The company stated, "The direct tariff impact was $1.9 million." Murray said the company received a refund of approximately $5.7 million, but the company is still "evaluating the new tariff policies."
