Performance Analysis

AOI delivered a transformative quarter, with total revenue doubling year over year and gross margin expanding by over 1,000 basis points, reflecting a decisive shift in business mix and operational scale. The CATV segment, now comprising 65% of revenue, saw sales surge more than sixfold from the prior year, fueled by 1.8 GHz amplifier orders from a major North American MSO, and driving overall margin outperformance. Data center revenue, accounting for 32% of the business, grew 11% year over year but dipped sequentially due to inventory digestion at a hyperscale customer and supply constraints on legacy 100G products.

Gross margin improvement was attributed to favorable product mix and operational leverage, particularly in CATV, where margin now outpaces data center by 300 to 600 basis points. Operating expenses rose with R&D and G&A investments to support capacity expansion and customer qualification activity, but loss narrowed sharply as scale and mix improved. Notably, AOI generated positive non-GAAP EBITDA, signaling progress toward sustainable profitability as it executes on high-velocity CapEx for U.S. and Taiwan manufacturing.

• CATV Segment Scale: CATV revenue hit $64.5 million, up 24% sequentially and 6x year over year, reflecting record amplifier demand and near full manufacturing utilization.
• Data Center Transition: Data center revenue reached $32 million, with 78% from 100G products; supply constraints and inventory digestion weighed, but 800G qualifications and design wins set up a second-half ramp.
• Margin Expansion: Gross margin rose to 30.7%, above guidance, with further gains expected as U.S. automation and higher-value products scale.

AOI’s capital allocation is now tightly focused on expanding 400G, 800G, and 1.6T transceiver production, with $30.5 million deployed in Q1 and full-year CapEx projected at $120–$150 million, funded in part by a $98 million at-the-market equity raise. Inventory levels rose to support both CATV and data center product ramps, with management confident in inventory telemetry and customer deployment visibility.

Executive Commentary

Strategic Positioning

1. CATV as Margin Engine

The CATV segment has emerged as AOI’s margin and cash flow anchor, delivering record revenue and higher gross margin due to limited product diversity and strong customer pull from cable MSO network upgrades. Management’s direct telemetry and customer reporting provide high confidence in inventory visibility and deployment pace, mitigating channel risk as amplifier demand remains robust through Q3.

2. U.S. Manufacturing and Tariff Advantage

AOI’s accelerated U.S. production buildout for 800G and 1.6T transceivers is a direct response to hyperscaler demand for secure, TAA-compliant, and tariff-resilient supply chains. By year-end, Texas capacity will reach 40,000 units per month, with plans to quintuple output by mid-2026. Automation and domestic laser chip sourcing are expected to drive both cost and margin advantages, while customer willingness to pay a premium for U.S.-made optics supports price realization.

3. Data Center Customer Diversification

While the Amazon agreement is a marquee win, AOI is actively engaging with other hyperscale and cloud providers, leveraging its domestic manufacturing edge and TAA compliance to expand share. Recent design wins were with non-Amazon hyperscalers, and management expects further inroads as customers diversify supply and qualification cycles progress through 2025.

4. CapEx-Driven Expansion and Funding Discipline

Heavy CapEx outlays are central to AOI’s growth thesis, with $98 million raised via ATM and additional customer partnership funding under consideration. The focus is on scaling U.S. and Taiwan production for new-generation transceivers, with management emphasizing positive EBITDA and anticipated full-year profitability to support self-funded growth beyond the current investment cycle.

5. Product Roadmap and Market Timing

AOI’s 800G ramp aligns with hyperscaler deployment cycles, with management confident that demand for 800G will remain strong even as 1.6T adoption begins, given current customer requirements and the nascent volume for 1.6T (primarily at Nvidia and Google). Qualification processes are lengthy but progressing, with large volume orders expected as customers complete final phases.

Key Considerations

AOI’s Q1 marks a strategic transition, with execution on capacity expansion and customer diversification setting the tone for the rest of 2025. The company’s ability to balance CATV margin capture with the capital-intensive data center ramp will determine the sustainability of its growth and profitability trajectory.

Key Considerations:

• CATV Inventory Control: Direct customer reporting and telemetry provide high visibility into amplifier deployment, reducing risk of inventory overhang as demand remains robust through Q3.
• 800G Ramp Execution: Second-half revenue and margin hinge on timely qualification and scale-up of U.S. and Taiwan 800G production, with material revenue expected in Q3.
• Tariff and TAA Compliance: AOI’s U.S. and Taiwan manufacturing footprint reduces exposure to China tariffs and positions the company as a preferred supplier for government and hyperscale contracts.
• Capital Allocation and Funding: ATM proceeds and positive EBITDA support aggressive CapEx, but operational cash flow must improve to sustain multi-site expansion without further dilution.
• Customer Concentration Risk: Two customers account for 91% of revenue (one CATV, one data center), underscoring the importance of ongoing design wins and diversification efforts.

Risks

AOI faces execution risk in scaling U.S. and Taiwan production, particularly as 800G qualification cycles are long and customer requirements for AI data center optics are stringent. Customer concentration remains high, and any delay in hyperscale ramps or CATV deployment could impact revenue and margin. Tariff policy shifts and supply chain disruptions are ongoing external variables, though AOI’s domestic investment mitigates some of this exposure.
