Management Comments

• Since our Chief Executive Officer, Mr. Sam Rubin, joined the Company in 2020, we have been developing a new strategy that will transition the Company from a pure component manufacturer to a supplier of imaging subsystems and systems.
• This transition, which is occurring both organically and through acquisitions, such as the July 2023 acquisition of Visimid Technologies and the February 2025 acquisition of G5 Infrared, is positioning the Company for significant growth and higher profitability in coming years.
• We refer to this ecosystem as optical engineered solutions, and believe we are positioned to serve as a single source, global provider of optical solutions with leading engineering and manufacturing capabilities.
• The complementary nature of the LightPath materials and optics capabilities and G5 Infrareds system level camera quickly led the teams to start working together resulting in new products that have been announced already (such as the Germanium-free cameras) or that are in development.
• To the best of our knowledge, we are the first to offer a midwave uncooled camera that does not require any Germanium.
• We have taken proactive steps to minimize the orders we accept for Germanium products and therefore minimize our exposure to this risk.
• We continue to diversify our business in order to minimize our sales concentration risk.
• Management, after reviewing with legal counsel all of these actions and proceedings, believes that the aggregate losses, if any, will not have a material adverse effect on the Company's financial position or results of operations.
• We do not expect to incur additional legal fees or consulting expenses in future periods as we have exhausted nearly all of our legal options and remedies [regarding former China management malfeasance].
• While LightPath Technologies faces various cybersecurity threats as part of routine operations, no risks have been identified to date that could materially impact the company's operations, strategy, financial condition, or overall business performance.

Industry Context

The photonics industry is undergoing a significant transformation, moving from a fragmented, component-oriented supply chain to a solution-focused model.

Key Dates

Recommendation

LightPath Technologies is undergoing a significant strategic transformation towards higher-value infrared imaging systems and solutions, supported by key acquisitions and proprietary BlackDiamond materials. This shift, coupled with strong revenue growth and a substantial increase in backlog, indicates positive long-term potential. However, the company continues to report significant net losses, negative cash flow from operations, and increased operating expenses, including non-recurring acquisition costs and interest expenses. While the recent $8.0 million capital raise provides some liquidity, the company's accumulated deficit and ongoing need for additional capital present financial risks. The reliance on a few key customers and geopolitical supply chain risks for critical materials like Germanium also warrant caution. Given the promising strategic direction and technological advancements balanced against persistent profitability challenges and financial leverage, a 'hold' recommendation is appropriate for investors to monitor the execution of the strategy and progress towards sustained profitability.
