LightPath Technologies, Inc. (LPTH)

LightPath makes optics, the lenses and glass that focus light, above all for infrared imaging, the thermal cameras at the center of its growth. It sells at every level of the chain: raw optical glass, including its own BlackDiamond infrared glass; molded and machined lenses for infrared and visible light; lens assemblies; and whole cameras, uncooled thermal cameras made in Texas and cooled long-range surveillance cameras made in New Hampshire. It also bills engineering work, designing new products that it later makes for the customer. It calls the move from parts to assemblies and cameras LightPath 2.0 and 3.0: components once sold for single dollars or tens of dollars, assemblies for hundreds, and cameras and systems for tens of thousands and sometimes hundreds of thousands. 181920212223

Its customers are mainly defense prime contractors and system integrators that build its materials, lenses, assemblies and cameras into their own systems, along with government agencies and makers of industrial, laser, inspection and medical equipment; it sells to integrators rather than end users. Sales are concentrated and shifting: in fiscal 2026 three customers took about 37% of revenue, one of them 24%, against 23% for the top three a year earlier, and two of fiscal 2025's three largest customers were not among fiscal 2026's three largest. Named programs include a missile program with Lockheed Martin and long-range cameras for border patrol and counter-drone systems. 24252627

Sales are counted by where products ship. In fiscal 2026, 48% of revenue came from outside the United States, up from 38%, nearly all of it (97%) from customers in Europe and Asia; the company adds that one of its largest customers assembles in Europe and ships to its own customers in the United States, so the foreign share overstates it. It makes its products in Orlando, Florida, where it has its headquarters; Riga, Latvia; Hudson, New Hampshire; Plano and Garland, Texas; and Zhenjiang, China. In July 2026 it agreed to sell the Zhenjiang business to Hengtu Optical Technology, owned by members of that plant's management, for $4,500,000 payable within five years of closing, which is expected in September 2026; the plant is to keep supplying LightPath as an outside vendor. 2829303132333435

It buys optical glass from many suppliers, among them CDGM Glass, Ohara and Sumita Optical Glass, and infrared crystal and glass from suppliers around the world, and it melts its own BD6 chalcogenide glass in Orlando as a low-cost internal source. Some key materials, including germanium and sensors, come from single or limited sources. Germanium is the pinch point: the filing estimates that over 60% of world supply comes from China, which began restricting its export in July 2023 and in December 2024 barred dual-use exports to US military users. LightPath has cut the germanium orders it accepts and is redesigning customers' systems around its BlackDiamond glass. 36373839404142

The specifics

LightPath was incorporated in Delaware in 1992, the successor to a partnership formed in 1989 and a corporation formed in 1985, and for most of its life made precision molded lenses for visible light. It bought ISP Optics, an infrared optics maker with a plant in Riga, in December 2016; Visimid Technologies, a thermal imaging and night vision design firm in Plano, Texas, in July 2023; G5 Infrared, a maker of cooled long-range infrared cameras in Hudson, New Hampshire, in February 2025, for consideration valued at about $27.1 million; and the assets of Amorphous Materials, an infrared glass maker in Garland, Texas, in January 2026, for at most $10.0 million. Share sales brought in about $120.2 million net in fiscal 2026. 4344454647484950513552535420

Its edge is BlackDiamond, a family of chalcogenide glasses, glasses that pass infrared light, which it melts itself and offers in place of germanium. The most important, the BDNL glasses, come from an exclusive license the US government granted in December 2021 for materials developed by the Naval Research Lab; the first, BDNL-4, went on sale in April 2024. Some keep their focus as temperatures change and some work across more than one band of the spectrum, which lets its Mantis camera see in both midwave and longwave infrared. Molded lenses are the original LightPath technology; it calls itself the original developer of precision glass molding. It relies mainly on trade secrets and know-how, with a recent patent on flame detection, an allowed application for heated lenses that clear ice and fog, and a pending one on calibrating cameras without a shutter. 55565758596061626364

It names competitors by product: makers of diamond-turned germanium, silicon and zinc selenide optics in infrared; volume molders of aspheric lenses in Asia in visible light; and in assemblies and cameras, catalog sellers such as Ophir Optronics (part of MKS Instruments), Controp Precision Technologies, Teledyne FLIR and Clear Align. Its largest customers can be rivals too: Lockheed Martin, Anduril Industries, Teledyne FLIR, RTX and Elbit Systems design optical assemblies in house. 65666768

Defense rules shape the business. The Orlando plant is registered with the US State Department under ITAR, the arms export rules, a registration that covers Plano and Hudson too, and the Riga plant holds an ITAR license to make controlled items. The Defense Department, the Defense Logistics Agency, the European Space Agency and the US Army have funded work to qualify its glasses. Switching a complex defense or airborne system to a new glass can take up to two years to requalify, and once qualified, a material tends to stay for the life of a program. 69707172

What drives growth, line by line

Revenue for the year to June 2026 rose 93% to $71.7 million from $37.2 million, the first year with G5 Infrared for all twelve months (the prior year had it for less than five) and with AML from January. Gross margin rose to 36% from 27%. The company still lost $19.7 million from operations and $20.5 million in all, mainly because the earnouts owed for G5, payments tied to its results, came in $14.1 million above what was recorded when it was bought. 737475767778

Assemblies and Modules. Now the largest line: $31.9 million, up 281%, and 44% of revenue against 23% a year earlier. G5 Infrared's cameras and modules brought about $23.1 million of the $23.5 million increase, including the program with a large global technology customer and other defense and security buyers, mainly for border patrol and counter-drone systems. The filing says these products typically carry higher gross margins than components. 797480

Infrared Components. $21.2 million, up about 52%, roughly three tenths of revenue. G5's coating services added about $1.3 million and the newly bought AML about $2.2 million; the remaining $3.8 million came from higher sales to defense and industrial customers in the United States and Europe. 81

Visible Components. $15.5 million, up 32%, on sales to industrial customers in Asia, the United States and Europe. The company says the sale of its Chinese subsidiary will reduce visible components revenue once it closes, which it expects in September 2026. 82

Engineering Services. Nearly flat, and the smallest line. Less came from Visimid's contract with Lockheed Martin, a matter of timing, offset by an engineering project for another defense customer. The company expects engineering revenue from a current Lockheed Martin program to decline as the program moves from development into production, with new programs bringing comparable or higher engineering revenue. 8384

What comes next, in the company's own words: backlog stood at $110.9 million at June 30, 2026, with about $85.6 million due for delivery within a year; the year's $73.6 million increase includes about $58.0 million of orders from a leading global technology customer for advanced infrared camera systems to ship in calendar 2026 and 2027. It anticipates higher capital spending in fiscal 2027 to support that backlog. 858687

What the desk infers Inferred

1. Inferred

   The customer that took 24% of fiscal 2026 revenue is most likely the large global technology customer whose camera program drove G5 Infrared's growth, not a defense prime contractor.

   Because

   • One customer took 24% of fiscal 2026 revenue, when the largest a year earlier took 9%, and two of fiscal 2025's three largest customers fell out of the top three. 2526
   • G5 Infrared's camera and module sales rose about $23.1 million, including the previously announced program with a large global technology customer. 79
   • Backlog includes about $58.0 million of orders from a leading global technology customer for advanced infrared camera systems. 86
   Confidence 65 of 100Wrong if A filing or disclosure that identifies the customer behind 24% of fiscal 2026 revenue as a defense prime contractor or a government agency.
2. Inferred

   About three quarters of fiscal 2026's added revenue came from businesses bought in 2025 and 2026, above all G5 Infrared, rather than from LightPath's original lens lines: the company is growing as much by buying as by selling more of what it already made.

   Because

   • Revenue rose from $37.2 million to $71.7 million. 73
   • G5 Infrared's cameras and modules added about $23.1 million. 79
   • G5's coating services added about $1.3 million and AML about $2.2 million, while other infrared sales rose $3.8 million. 81
   • Visible components, made by the original business, rose $3.8 million, and engineering services were nearly flat. 8883
   • The prior year included G5 Infrared for less than five months. 75
   Confidence 80 of 100Wrong if A filing breaking out organic revenue that shows the businesses LightPath owned before February 2025 supplied most of fiscal 2026's revenue growth.
3. Inferred

   Much of the visible components line is made at the Zhenjiang plant LightPath is selling, the low-cost volume site behind its original molded-lens business.

   Because

   • The Zhenjiang plant was the lower-cost site for larger volumes of optical components and assemblies, with a precision glass molding area and coatings for visible optics. 3189
   • Visible components compete mostly on unit price at volume against molders in Asia. 66
   • The year's visible components growth came mainly from industrial customers in Asia, and the company says the sale will reduce visible components revenue. 82
   Confidence 70 of 100Wrong if A filing showing that most visible components revenue comes from lenses molded in Orlando rather than in Zhenjiang.
