First Quarter 2027 Earnings Conference Call - AELUMA INC

Financial Performance:

• Q1 FY2027 revenue was $568,000, a decrease from $1.4 million in Q1 FY2026, primarily driven by government R&D contracts.
• GAAP net loss widened to $3.8 million ($0.19 per share) compared to $1.5 million ($0.09 per share) in the prior year period.
• Adjusted EBITDA loss increased to $2.7 million from $450,000 year-over-year, reflecting strategic investments in headcount, product development, and operational capabilities for commercialization.
• The balance sheet remains strong with $53.9 million in cash and cash equivalents (down from $56 million), and the company is debt-free.
• The company is awaiting finalization of a potential CHIPS program award of up to $30 million, subject to definitive agreements.

Guidance and Future Outlook:

• Management anticipates the AI infrastructure build-out (starting in 2025) will reach an aggregate investment of $10.3 trillion by 2032.
• Significant commercial volume ramps are expected to begin in fiscal years 2028 through 2033, driven by the adoption of "slow and wide" transceiver architectures.
• The company is prioritizing funded R&D programs aligned with commercial priorities through the remainder of fiscal 2027 to support customer-driven technology development.
• Future revenue streams are expected to transition from current R&D contracts to non-recurring engineering (NRE) fees and commercial product sales, with qualification timelines ranging from 9 to 18 months.

Business Segments and Product Lines:

• Core technologies under development include "LINX" series high-speed photodetectors (micro-detectors) for slow and wide architectures and "Quasar" quantum dot lasers for scale-up and scale-out interconnects.
• Both key product lines utilize MOCVD technology on gallium arsenide and silicon substrates, eliminating reliance on constrained indium phosphide substrates.
• An agreement was announced with Axtron to procure G10 arsenide-phosphide MOCVD systems capable of processing 150mm (6-inch) and 200mm (8-inch) substrates to expand capacity for next-generation products.
• Partnerships include Sumitomo Chemical Advanced Technologies for MOCVD wafers and ongoing discussions with potential customers regarding NRE investments and large-volume agreements for the 2028–2032 timeframe.

Market and Competitive Landscape:

• Industry trends are shifting toward "slow and wide" transceivers and micro-packaged optics (NPO/CPO) to mitigate power and distance limitations of traditional copper and current optical modules in AI rack-scale clusters.
• Strategic standardization efforts are underway via the OCP's SRMO workstream and the OCI-MSA to define open, interoperable optical interconnect specifications.
• The semiconductor photonics supply chain faces constraints, particularly regarding indium phosphide fab capacity, prompting major players like NVIDIA to invest in expanding Indium Phosphide manufacturing.
• Aluma positions itself as a disruptor by offering scalable manufacturing on existing GaAs and silicon fabs, competing with established players like Lumentum and Coherent who are moving toward integrated optical solutions.

Risks and Challenges:

• Indium phosphide substrate supply constraints could impact competitors reliant on this material, though Aluma's technology is not affected.
• The commercial ramp is long-term (2028+), requiring continued capital investment in capacity and R&D before significant revenue realization.
• The CHIPS program funding remains subject to final contract negotiations and regulatory conditions.
• Customer qualification processes for custom devices can take 9 to 18 months, delaying immediate revenue generation from specific product lines.

Management Commentary and Tone:

• Management expressed confidence in the company's disruptive MOCVD-based technology and its ability to leverage existing fab infrastructure without requiring new qualified facilities.
• The tone was strategic and forward-looking, emphasizing the alignment of Aluma's technology with the massive scale of the AI datacom build-out.
• CEO Jonathan Clampkin highlighted the company's unique position to serve multiple layers of the value chain, including hyperscalers, tier-one suppliers, and system integrators.
• CFO Christopher Stewart emphasized maintaining fiscal discipline while scaling operations to meet anticipated market demand.

Analyst Questions and Answers:

• Capacity & Timeline: Clarified that the new Axtron MOCVD tools are for capacity expansion and advanced development rather than immediate commercialization, as current capacity via Sumitomo and internal resources is sufficient for the near term.
• Wafer Sizes: Confirmed current capability scales up to 300mm (12-inch) substrates; the new Axtron tools are configured specifically for 150mm (6-inch) and 200mm (8-inch) processing.
• Customer Engagement: Discussed engagements across the entire value chain (hyperscalers, tier-ones, module makers), noting the complexity of partners who may be both customers and competitors.
• Technology Focus: Confirmed "slow and wide" architectures are a primary growth driver, with significant demand for micro-detectors and micro-emitters, particularly in the near-infrared and shortwave infrared spectra.

Other Key Points:

• The company does not use indium phosphide substrates or fabs, distinguishing its manufacturing approach from many competitors in the AI optical space.
• Aluma is actively developing standard product offerings alongside customer-specific custom solutions.
• The "slow and wide" concept allows for power conservation by spreading information across modest channel counts, offering inherent redundancy and scaling room compared to high-speed narrow channels.
• The Q&A session reiterated that while laser suppliers are currently sold out for the next year, the significant volume ramp required for future AI clusters creates a specific window of opportunity for Aluma in the 2028+ timeframe.
