Operating expenses rose in line with growth investments, and AOI ended the quarter with a robust cash position, supported by increased debt and equity financing to fund capacity expansion.

• Data Center Demand Surge: 800G and 1.6T product orders from multiple hyperscalers are driving the bulk of new growth.
• CATV Stability: Amplifier shipments to a core customer remain a steady revenue base, with upside from new MSO clients.
• Margin Progression: Management expects automation and higher-value mix to drive gross margin toward 35% by year-end and 40% in 2027.

The company’s results and guidance reflect a supply-constrained scenario, with actual customer demand exceeding what AOI can deliver until new capacity comes online in Texas and Asia. The focus now shifts to execution on this expansion and the operational ramp of next-generation products.

Executive Commentary

Strategic Positioning

1. Data Center Optical Leadership

AOI’s rapid growth in 800G and 1.6T transceivers positions the company as a key enabler of hyperscale AI data center buildouts. Volume orders from multiple major cloud customers, including new long-term agreements, validate AOI’s product roadmap and manufacturing credibility. Customer concentration remains high, but deepening relationships with leading hyperscalers provide significant revenue visibility and scale leverage.

2. Manufacturing Scale and Automation

Capacity expansion in Texas and Asia is central to AOI’s growth plan, with new facilities and in-house automation platforms enabling rapid scaling and flexibility across product generations. The company’s proprietary equipment and automation mitigate supply chain and labor risks, allowing for faster and more reliable ramp-up compared to competitors. By year-end, AOI targets 650,000 units/month of high-speed products, with over half of future output from U.S. facilities by 2027.

3. Vertical Integration in Laser Manufacturing

AOI’s in-house indium phosphide laser fabrication is a strategic differentiator as industry-wide shortages persist. This vertical integration not only supports product development but also insulates the company from externally sourced laser bottlenecks, a key risk for many rivals. Major investments are underway to grow laser capacity by 350% through 2027, supporting both transceiver and emerging co-packaged optics (CPO) markets.

4. Margin Expansion Roadmap

While current gross margins are compressed by ramp costs and mix, management expects a step-change improvement as automation, scale, and higher-margin products take hold. The shift from 400G to 800G and 1.6T, coupled with operational efficiencies, is projected to drive margins above 35% by late 2026 and toward 40% as CPO and advanced lasers scale in 2027.

5. CATV and Diversification

CATV remains a reliable, cash-generating segment, providing a base for investment in growth areas. New MSO customer wins and amplifier demand support annual revenue targets, while software solutions are expected to begin contributing in 2026.

Key Considerations

AOI’s quarter reflects a business at the center of AI infrastructure buildout, but with growth gated by its own ability to scale manufacturing and supply chain. The following factors are pivotal for investors tracking the company’s trajectory:

• Capacity Ramp Execution: Timely build-out and qualification of new Texas and Asia facilities are essential to realize the full revenue pipeline.
• Laser Supply Chain Control: In-house laser manufacturing and substrate sourcing are critical to avoid industry-wide shortages and ensure delivery on long-term customer agreements.
• Margin Recovery Path: The pace at which AOI can shift mix and optimize automated processes will determine how quickly margins rebound toward target levels.
• Customer Concentration Risk: While hyperscaler relationships drive growth, they also concentrate risk; expansion into new customers or geographies could improve resilience.
• Capital Allocation Discipline: Large, ongoing CapEx commitments require careful balancing of cash, debt, and equity to support growth without diluting returns.

Risks

AOI’s reliance on a handful of hyperscale customers creates exposure to order volatility, qualification delays, and pricing pressure. Execution risk around capacity build-out—particularly equipment qualification and supply chain for indium phosphide substrates—could limit revenue realization if not managed tightly. Industry competition is intensifying, with contract manufacturers entering transceiver production, though AOI’s laser integration may offer some insulation. Macro factors, such as trade policy or component shortages, could also disrupt forecasts.

Forward Outlook

For Q2 2026, AOI guided to:

• Revenue between $180 million and $198 million
• Non-GAAP gross margin of 29% to 30%
• Non-GAAP net income ranging from a loss of $2.5 million to income of $2.8 million

For full-year 2026, management raised guidance:

• Revenue expected to exceed $1.1 billion
• Non-GAAP operating profit over $140 million

Management emphasized that growth is constrained by production capacity, not demand, and expects sequential revenue acceleration in Q3 and Q4 as new facilities come online. Gross margin is projected to improve as product mix shifts and automation efficiency increases.

• Capacity build-out and customer qualifications are the main determinants of near-term upside.
