1. Dependence on a limited number of customers and large contracts: CPS Technologies experienced a decline in revenue and a shift to losses in the fourth quarter of 2024, primarily due to the completion of a significant defense contract. Furthermore, three customers collectively accounted for 60% of the company's revenue in 2023 and 53% in 2022, indicating a substantial customer concentration. The loss of any major customer would be challenging to replace and could have a material adverse effect on the business and its financial condition.
2. Cash burn and need for additional financing: As of June 2025, CPS Technologies had a cash runway of approximately seven months, having burned through US$5.7 million in the preceding year. This short runway suggests that the company must either substantially reduce its cash expenditure or secure additional funding imminently to sustain its operations and growth plans.
3. Cybersecurity risks: Cybersecurity is an increasing concern for both management and investors at CPS Technologies. The company is actively working towards full compliance with NIST 800-171 to mitigate these risks, but the threat of a cybersecurity incident persists.

CPS Technologies (symbol: CPSH) operates in several key markets with its advanced material solutions, primarily focusing on metal matrix composites (MMCs), hermetic microelectronic packages, and advanced materials for aerospace and defense, including armor products.

Addressable Markets for CPS Technologies' Main Products and Services:

• Metal Matrix Composites (MMCs): The global metal matrix composite market size was estimated to be between approximately USD 460.9 million and USD 1.73 billion in 2024. Projections indicate growth to a range of approximately USD 811.5 million to USD 2.96 billion by 2032-2033, with Compound Annual Growth Rates (CAGRs) typically between 5.7% and 7.0% during the forecast periods. These materials are crucial for thermal management in high-density electronics, wireless communications, high-performance microprocessors, and motor controllers.
• Hermetic Microelectronic Packages: The global hermetic packaging market was valued between approximately USD 2.16 billion and USD 4.21 billion in 2024. This market is projected to grow to approximately USD 5.90 billion to USD 7.36 billion by 2030-2032, at CAGRs ranging from 6.9% to 7.49%. Hermetic packages are used in military, electronics, satellite, and aerospace applications to protect sensitive components from environmental factors.

CPS Technologies (symbol: CPSH) is expected to drive future revenue growth over the next 2-3 years through several key initiatives and market trends:

1. Increased Production Capacity and Manufacturing Efficiency: CPS Technologies has been focused on enhancing its operational capabilities to meet growing demand. The company implemented a third production shift in late 2024 and has consistently improved manufacturing throughput. A significant future driver is the planned move to a larger manufacturing facility in 2026, which is expected to nearly double its usable space, funded by a recent secondary offering of over $9.5 million. This expansion is crucial for supporting higher production rates and increased shipments across its product lines.
2. Strong Demand and New Contracts in the Power Module and Semiconductor Markets: The company has reported record revenues, largely fueled by robust customer demand, particularly in the power module and metal matrix composite markets. A notable driver is a new $15.5 million contract secured with a multinational semiconductor manufacturer for power module components, expected to contribute steadily to revenue over the next year. This indicates continued strength in key industrial sectors.
3. Expansion in Government and Defense Contracts: CPS Technologies is actively growing its involvement in federally funded research and development initiatives. The company is advancing several projects, including a $1.15 million Army contract for developing a controlled fragmentation warhead. Additionally, CPS has secured multiple Small Business Innovation Research (SBIR) development contracts, including four in 2025, which strengthen its position in government-funded projects and are expected to drive future revenue.
4. New Product Introductions and Market Outreach: CPS Technologies is broadening its product catalog and market reach through the commercialization of new materials. A significant example is the first commercial order received for its AlMax™ fiber-reinforced aluminum composites. This focus on innovation and expanding its core offerings to new and existing customers is anticipated to contribute to sustained revenue growth.
