Aeluma (ALMU) primarily sells its advanced silicon photonics products and integrated laser solutions to other companies (B2B customers). Their technology is critical for high-performance applications such as artificial intelligence/machine learning (AI/ML), high-performance computing (HPC), and data center infrastructure.

According to Aeluma's Annual Report on Form 10-K for the fiscal year ended December 31, 2023, the company reported significant customer concentration:

• For the year ended December 31, 2023, one major customer accounted for approximately 78% of total revenue.

While Aeluma's SEC filings indicate a highly concentrated customer base with a single dominant customer in 2023, the specific name of this customer is not disclosed in publicly available documents. In the specialized B2B technology sector, particularly for component and subsystem suppliers, direct customer names are frequently kept confidential for competitive and strategic reasons.

The key risks to Aeluma's (ALMU) business are primarily rooted in its early-stage development, funding requirements, and customer concentration.

1. Unprofitability and Early-Stage Operations: Aeluma is characterized as a speculative, early-stage enterprise that has not yet achieved profitability at the operating or net income levels. The company is expected to continue experiencing net losses and negative cash flows from operations, with consensus not anticipating a positive bottom line even by the end of fiscal year 2027. This lack of sustained profitability makes it difficult to evaluate its long-term business prospects and creates uncertainty regarding its ability to successfully offer, market, and distribute its products or services.
2. Dilution Risk: To fund its operations and transition to commercialization, Aeluma has a Shelf S3 registration worth $100 million, a portion of which has already been utilized through the issuance of new shares. With a significant portion of this capital yet to be used, existing shareholders face the risk of substantial further dilution of their holdings as the company continues to raise capital.
3. Customer Concentration: Aeluma faces significant risk due to its high reliance on a very limited number of customers. In 2025, a substantial 71% of the company's revenue was derived from just one customer. The potential loss of this key customer could have a severe adverse impact on Aeluma's revenue generation and overall financial stability.

• Intensifying Vertical Integration and Ecosystem Dominance by Large Semiconductor & Network Giants: Aeluma operates in a market increasingly influenced by major players like Broadcom, Intel, and Marvell. These companies possess immense financial resources, established customer relationships with hyperscale data centers (Google, Amazon, Microsoft, Meta), and often their own manufacturing capabilities. As demand for high-speed optical interconnects, particularly for AI applications, escalates, these giants are increasingly pursuing vertical integration, developing comprehensive solutions from chips to networking systems. This trend allows them to offer "one-stop shop" solutions and co-develop technologies directly with large customers, potentially locking Aeluma out of significant market share opportunities. The shift towards co-packaged optics (CPO) further amplifies this threat, as it requires deeper system-level integration that favors companies with broad portfolios and ecosystem control.

• Risk of Disruptive Alternative Photonic Platforms or Manufacturing Paradigms: While Aeluma's core technology leverages silicon photonics and its POET Optical Interposer platform, the broader integrated photonics industry is highly dynamic. Significant research and development continue in alternative material systems and integration approaches, such as Indium Phosphide (InP) on silicon, thin-film Lithium Niobate (TFLN), or other novel photonic materials. Should a competing platform emerge that offers fundamentally superior performance (e.g., lower power consumption, higher speed, better thermal management, or lower manufacturing cost) for future generations of optical transceivers and interconnects, it could erode Aeluma's competitive advantage. The rapid pace of innovation means that a paradigm shift in photonic integration could materialize, challenging the current silicon photonics-centric approach.

Aeluma (ALMU) is poised for future revenue growth over the next 2-3 years, driven by several key factors:

1. Expansion into High-Growth Markets with Advanced Semiconductor Products: Aeluma is strategically targeting rapidly expanding sectors, including AI infrastructure, defense and aerospace, mobile electronics, automotive, augmented/virtual reality (AR/VR), and quantum computing. The company's innovative InGaAs-on-Silicon technology and advancements in quantum dot photonic integrated circuits and InGaAs LiDAR sensors are crucial for capturing market share in these areas.
2. Securing and Expanding Government and Commercial R&D Contracts: A substantial portion of Aeluma's revenue growth is anticipated from securing new and extending existing research and development contracts. The company has successfully partnered with government agencies such as NASA, the U.S. Navy, the Department of Energy, and DARPA, along with commercial collaborators. These contracts provide non-dilutive funding and accelerate the development and commercialization of next-generation technologies.
3. Scaling and Commercialization of Proprietary Manufacturing Technology: Aeluma's proprietary platform, which integrates high-performance compound semiconductors with scalable, cost-effective silicon manufacturing, is designed for mass-market applications. The company is actively enhancing manufacturing readiness and expanding its business development efforts to translate these technological advantages into volume production and broad market adoption.
4. Growth of Recently Launched or Advanced Products, Particularly InGaAs LiDAR Sensors: Aeluma identifies InGaAs LiDAR sensors as an immediate and significant market opportunity. The company anticipates capturing a substantial revenue share in this segment by 2030, highlighting it as a key product for future growth.
