First Quarter 2027 Earnings Conference Call - AELUMA INC

Explicit Guidance:

• No specific quantitative financial guidance (e.g., revenue, earnings, margins, capex) provided for any future period.
• Qualitative outlook: Revenue for Fiscal Year 2027 is expected to originate solely from R&D contracts and commercial non-recurring engineering (NRE).
• Liquidity outlook: Maintained debt-free balance sheet with $53.9 million in cash and cash equivalents as of Q1 FY2027; no indication of immediate liquidity constraints.
• Capital allocation: Expect continued increases in investments in headcount, systems, and supply chain initiatives throughout the remainder of FY2027 to support commercialization.
• Grant funding: Potential CHIPS program award of up to $30 million remains subject to definitive agreements and conditions; no timing or amount guaranteed.

Business-Segment Outlook:

• Product Development: Development of LINX S-series photodetectors and Quasar quantum dot lasers continues; neither requires indium phosphide substrates or fabs.
• Timeline for Revenue: Significant volume ramps and commercialization of products (high-speed photodetectors, micro-detectors, micro-emitters) are expected to begin in 2028 through 2033.
• Capacity Expansion: Agreement secured with Axtron for MOCVD systems to scale manufacturing on 150mm and 200mm (6-inch and 8-inch) gallium arsenide and silicon substrates; capacity expansion and advanced development tools are in configuration.
• Customer Interactions: Expanded discussions with datacom customers regarding non-recurring engineering investments and product opportunities, with potential for "large volumes" to support the 2028–2032 build-out.
• Technical Focus: Near-term commercial opportunities target "slow and wide" architectures (micro-detectors/micro-emitters); long-term focus includes scaling to 300mm (12-inch) substrates.
• Partner Relationships: Ongoing collaboration with Sumitomo Chemical Advanced Technologies for wafer scaling; capacity commitments exist with partners for the foreseeable future.

Market and Competitive Outlook:

• Market Size: The U.S. AI infrastructure build-out, initiated in 2025, is projected to reach an aggregate investment of $10.3 trillion by 2032.
• Technology Trends: "Slow and wide" transceiver architectures (for distances up to 50–100 meters) are gaining industry traction at OCP and ECOC, offering power efficiency and redundancy over traditional copper and CPO/NPO for rack-scale scaling.
• Competitive Landscape: Major ecosystem shifts noted with Marvell's proposed acquisition of Lumentum and NVIDIA's investments in Coherent/Lumentum to expand indium phosphide capacity; Illumis distinguishes itself by avoiding indium phosphide constraints.
• Demand Dynamics: Laser suppliers report sold-out capacity for the near term; supply constraints are driving demand for alternative manufacturing solutions (Gallium Arsenide/Silicon) that can scale rapidly.
• Sales Cycle: Customer-specific product qualification is estimated to take 9 to 18 months, aligning with the anticipated 2028+ ramp.
• Value Chain Engagement: Active discussions across hyperscalers, system integrators, and tier-one suppliers; some partners may act as both customers and competitors.

Macro / Industry Outlook:

• Supply Chain: Global AI infrastructure build-out is pressuring the supply chain, particularly regarding indium phosphide substrates and fab throughput; alternative semiconductor photonics solutions are becoming increasingly critical.
• Economic Drivers: Massive data center construction is driven by the need to support 1,000+ unit XPU-GPU clusters; traditional copper limits at high data rates are necessitating a shift to optical interconnects.
• Standardization: Industry momentum building around OCP SRMO workstream and OCI-MSA specifications to define open, interoperable optical interconnects for AI scale-up.
• Pricing Dynamics: Anticipated reduction in sales prices as technology volumes grow and become standardized.

Strategic Initiatives:

• Capacity Additions: Procuring Axtron G10 arsenide-phosphide MOCVD systems configured for proprietary, non-indium phosphide processes to support 150mm and 200mm substrate scaling.
• Technology Commercialization: Transitioning from R&D to commercial product offerings, specifically leveraging the heterogeneous integration platform for high-speed photodetectors and quantum dot lasers.
• Market Expansion: Leveraging scalable MOCVD-based technology for both "slow and wide" (within-rack) and "fast and narrow" (across-data center) architectures.
• Partnerships: Strengthening relationships with Sumitomo Chemical and Axtron to enable scalable manufacturing without building new fabs from scratch.

Risks and Headwinds to Outlook:

• Timeline Uncertainty: Commercial ramps and significant revenue generation are not expected until 2028–2033; near-term revenue remains limited to R&D and NRE.
• Customer Qualification: Product qualification processes can take 9 to 18 months, delaying potential revenue recognition.
• Supply Chain Constraints: Indium phosphide substrate supply remains constrained, potentially impacting competitors and the broader ecosystem, though Illumis claims a mitigated risk through alternative materials.
• Regulatory/Grant Risk: The potential $30 million CHIPS program funding is not finalized and is subject to definitive agreements and conditions.
• Pricing Pressure: Future price erosion is anticipated as volumes increase and the technology becomes commoditized.
• Competitive Landscape: Potential shifts in partner dynamics, where tier-one suppliers may serve as both partners and competitors.

Management Tone on the Future:

• Confidence: High confidence in the "vast opportunities" for Illumis technologies within the AI datacom sector and the strategic advantage of avoiding indium phosphide dependencies.
• Cautious Optimism: Management expresses "pleasure" with progress toward commercialization and acknowledges the urgency of market demand but emphasizes "fiscal discipline."
• Strategic Patience: Willingness to accept a longer timeline (2028+) for significant ramps in exchange for superior scalability and capacity flexibility.
• Differentiation: Strong emphasis on the "disruptive" nature of their semiconductor photonics manufacturing approach, which is gaining traction as the ecosystem seeks scalable solutions.

Miscellaneous:

• Clarification: The new Axtron MOCVD system is an "accelerant" for capacity expansion and is not required for immediate commercialization; current capacity from in-house assets and Sumitomo is deemed sufficient for the foreseeable future.
• Product Specifics: The "slow and wide" architecture targets near-IR/short-wave infrared data rates (~50 Gbps per channel) to balance power, complexity, and fiber count, distinguishing it from visible light micro-LED approaches.
• Geographic Focus: Discussions highlighted at European (Malaga, Spain) and Global Summits, indicating a broad, global industry validation of the technology path.
