Third Quarter Fiscal 2026 & Subsequent Highlights:

Management Commentary

Sam Rubin, President and Chief Executive Officer of LightPath, said: “The third quarter of fiscal 2026 demonstrated continued execution against our vertically integrated strategy, with revenue growing 109% year over year to $19.1 million and gross profit expanding 161% year over year to $7.0 million. We delivered our third consecutive quarter of positive adjusted EBITDA and ended the quarter with a record order backlog of $110.6 million, up 196% from the start of the fiscal year. The scale and quality of our backlog is the clearest indication yet that LightPath has established itself as a mission critical supplier for some of the most important optical and infrared imaging programs in the U.S. and allied defense industrial base.

“The strategic thesis we have been executing against for the past several years continues to be reinforced by customer behavior and U.S. government policy. The Fiscal Year 2026 National Defense Authorization Act directs the U.S. Department of War to eliminate reliance on optical glass and optical systems sourced from certain foreign nations by January 1, 2030. Our broad offering of BlackDiamond™ chalcogenide glasses, including those licensed exclusively from the U.S. Naval Research Laboratory, along with our infrared cameras, assemblies, and thermal imaging systems, are already designed, manufactured, and delivered in alignment with those requirements. With the addition of AM, we now operate two U.S. based BlackDiamond™ glass production sites and have expanded our infrared glass portfolio to roughly 20 proprietary compositions, which is among the broadest selection of infrared materials available anywhere.

“Our February Investor Day laid out where we go from here. We are organizing the business around three pillars of growth: optical assemblies, infrared camera systems, and large defense programs of record. Each pillar has an addressable market measured in hundreds of millions to billions of dollars, and each is enabled by the same underlying BlackDiamond™, molding, coating, and camera technologies. Programs such as NGSRI, SPEIR, Apache, border surveillance, and counter UAS are no longer theoretical; they are in production or nearing it, and they increasingly carry BlackDiamond™ content. We are on track to complete the redesign of G5’s cooled infrared camera family onto BlackDiamond™ by the end of summer 2026, and beleive that this will position LightPath to meet long range camera demand at scale while competitors continue to work through the Germanium supply constraint.

“With a strong balance sheet, two operating glass manufacturing facilities, an expanded camera portfolio, and a deeper senior commercial leadership team following the appointments of Doug Schoen and Ryan Workman, we believe LightPath is well positioned to continue converting our record backlog into revenue, expand margins as volume scales, and pursue further accretive M&A that accelerates our transition into a platform provider of mission critical optical and imaging solutions,” concluded Rubin.

Third Quarter Fiscal 2026 Financial Results

Revenue for the third quarter of fiscal 2026 increased 109% to $19.1 million, as compared to $9.2 million in the same quarter of the prior fiscal year. Revenue was split amongst the Company’s product groups in the third quarter of fiscal 2026 and the same quarter of the prior fiscal year as follows:

*** Numbers may not foot due to rounding

Gross profit increased 161.1% to $7.0 million, or 36% of total revenues, in the third quarter of fiscal 2026, as compared to $2.7 million, or 29% of total revenues, in the same year-ago quarter. The increase in gross margin as a percentage of revenue was primarily driven by the increase in revenue from assemblies and modules, which generally carry higher margins, as well as an improved infrared component mix and manufacturing yields.

Operating expenses for the third quarter of fiscal 2026 include a fair value adjustment of $3.4 million related to the G5 earnout liability, which will continue to be adjusted through operating expenses until it is fully paid out. Excluding this amount, operating expenses increased $1.8 million, or 30%, to $7.8 million for the third quarter of fiscal 2026, as compared to $6.0 million in the same year-ago quarter. The increase was primarily driven by integration of G5 Infrared and AM, increased sales and marketing spend, higher information technology spend to meet customer security requirements, and increased SG&A personnel costs.

Net loss in the third quarter of fiscal 2026 totaled $4.1 million, or $0.07 per basic and diluted share, as compared to $3.6 million, or $0.44 per basic and diluted share, in the same year-ago quarter. The year-over-year change in net loss was primarily attributable to the change in fair value of acquisition liabilities for the earnout related to the acquisition of G5 Infrared.

Adjusted EBITDA** for the third quarter of fiscal 2026 was $1.1 million, as compared to an adjusted EBITDA loss of $1.6 million for the same year-ago quarter. The increase was primarily attributable to the increase in gross profit, driven by higher sales, partially offset by increased SG&A and new product development costs.

Cash and cash equivalents as of March 31, 2026 totaled $55.2 million, as compared to $4.9 million as of June 30, 2025. Total backlog as of March 31, 2026 was approximately $110.6 million, an increase of 196% compared to $37.4 million as of June 30, 2025.

**Use of Non-GAAP Financial Measures

To provide investors with additional information regarding financial results, this press release includes references to EBITDA and adjusted EBITDA, which are non-GAAP financial measures. The Company calculates EBITDA by adjusting net income to exclude net interest expense, income tax expense or benefit, depreciation, and amortization. We also calculate adjusted EBITDA, which excludes, as applicable: (1) stock compensation expenses; (2) the loss on extinguishment of debt; (3) the effect of the non-cash income or expense associated with the mark-to-market adjustments, related to the warrants; (4) the effect of non-cash income or expenses associated with the fair value adjustments related to the acquisition earnout liabilities; (5) acquisition costs, including legal fees and due diligence; and (6) the effect of foreign exchange gains or losses.

A "non-GAAP financial measure" is generally defined as a numerical measure of a company's historical or future performance that excludes or includes amounts, or is subject to adjustments, so as to be different from the most directly comparable measure calculated and presented in accordance with GAAP. The Company's management believes that these non-GAAP financial measures, when considered together with the GAAP financial measures, provide information that is useful to investors in understanding period-over-period operating results separate and apart from items that may, or could, have a disproportionately positive or negative impact on results in any particular period. Management also believes that these non-GAAP financial measures enhance the ability of investors to analyze underlying business operations and understand performance. In addition, management may utilize these non-GAAP financial measures as guides in forecasting, budgeting, and planning. Non-GAAP financial measures should be considered in addition to, and not as a substitute for, or superior to, financial measures presented in accordance with GAAP. A reconciliation of these non-GAAP financial measures with the most directly comparable financial measures calculated in accordance with GAAP is presented in the table below.
