LightPath's Story Finally Printed — So Why Is the Tape Down 36% in Two Weeks?
FY26 revenue +93%, gross margin to 36%, a $110.9M order book, a China exit — and a stock still 49% off its May high

The Transformation Finally Prints
For three years LightPath management told a story about converting from a commodity optical-component maker into a vertically integrated infrared-systems house. On the fiscal Q4/FY26 call, CEO Sam Rubin opened by refusing to retell it: “Fiscal 26 is the first year in which the transformation we have been describing shows up cleanly in every line of the financial statements.” — Shmuel Rubin, Chief Executive Officer · 2026-09-10 The numbers back him. Full-year revenue rose 93% to $71.7M from $37.2M; fourth-quarter revenue of $21.2M was a company record and the fourth straight sequential gain. Gross margin expanded from 27% to 36%, with Q4 at 39.4% — and management was adamant it wasn't a one-off: “The 39.4% margin did not come from a 1 time favorable contract or from raising prices.” — Shmuel Rubin, Chief Executive Officer · 2026-09-10 Adjusted EBITDA swung from a $5.1M loss to a $4.2M profit, and the order book finished at $110.9M, up 197%. CFO Albert Miranda framed the two-year arc starkly: “2 years ago, this was a $32 million per year revenue business, with negative adjusted EBITDA, $3.5 million of cash.” — Albert Miranda, Chief Financial Officer · 2026-09-10 Now it carries $93.2M of cash against effectively no debt. Total revenue has roughly doubled year-over-year, and gross margin has clawed back from the low-20s toward the high-30s — though still well below the mid-50s of the mid-2010s.What's Genuinely New This Quarter
Three things are new, not boilerplate. First, the China exit. LightPath signed a definitive agreement to sell its China subsidiary for $4.5M, closing this month. “LightPath now does everything, melts glass, coats optics, builds cameras and assembly, exclusively outside of China.” — Shmuel Rubin, Chief Executive Officer · 2026-09-10 With a customer base now dominated by defense primes, that removes a structural barrier to bidding on covered-nation work. Second, Zoom camera is the company's #1 keyword this quarter — a brand-new theme with no precedent in the prior-12-quarter trajectory. Sam flagged first orders for uncooled zoom lenses and complete zoom cameras, a market slice gated by supply-chain availability rather than price. Third, large diameter melting: January's Amorphous acquisition unlocked up to 10 inches and beyond, versus the 5-inch ceiling previously. Large-diameter glass is what long-range cameras and space-based missile-tracking payloads physically require — the same class of product behind the precision munition and interceptor programs Sam says the company is now designing into across different platforms. On the competitive moat, Sam moved the goalposts in LightPath's favor. Asked about the window before alternatives to germanium arrive, he was unusually direct: “I feel like we actually have more time than I thought.” — Shmuel Rubin, Chief Executive Officer · 2026-09-10 He cited Umicore producing only 3–4 tons a year with a 4–5-year horizon — nowhere near solving the shortage. That extends the runway he described in February as “no earlier than three years, probably five years.” — Sam Rubin, CEO · 2026-02-11The Tape Is Voting Differently
Here's the contrast. The company is executing; the stock is not celebrating. LPTH sits 49.3% below its May 28 peak of $18.15, down 28% over 90 days and roughly 36% in the last two weeks alone. At a $857M market cap, the valuation multiple has already de-rated from its 2025 high. Some of this is mechanical — the June $50M primary raise diluted holders and a secondary sale by Northland Capital added supply. But a stock that drops sharply into a record quarter, then keeps falling after it, is telling you the market is discounting execution risk, not thesis risk. That reads as fair, because the bottleneck is now operational. Sam was blunt: “by far, glass is our biggest capacity constraint.” — Shmuel Rubin, Chief Executive Officer · 2026-09-10 Detectors are the next long pole, with lead times stretching from six months toward ten, and motors/mechanics behind them. Management guided FY27 CapEx higher than FY26 as a deliberate bet against a visible book — capital spending is running at its highest level since the 2023 Orlando expansion, which pressures near-term cash. Capex as a share of revenue has begun climbing as the company funds its own growth.The Optics of the Earn-Out — and the Real Risk
The reported income statement is unusually ugly for a company with a $4.2M adjusted EBITDA: a $15.6M non-cash charge from remeasuring the G5 earn-out, which by definition only grew because G5 beat plan. Miranda expects the majority of it behind them, with only small AML and Visimid adjustments left. Investors who glance at GAAP net loss will misread this quarter; those watching cash and adjusted EBITDA will not. The real risk is bandwidth. Rubin's own framing is the honest one:On the prior call, Miranda had already conceded that scaling would “slow down our ramp from where we are today, 36% to 40%, but not much.” — Albert Miranda, CFO · 2026-05-08 That margin guidance — a quarter or two of delay — is the thing to watch, because the entire bull case rests on holding 40% gross margins while tripling volume. Bottom line: this is a genuine name-in-motion — a company-unique product launch (Zoom camera), a structural pivot (China exit), and a lengthening competitive window against germanium — colliding with a tape that has already cut the stock in half from its high. The thesis is now an execution question, not a narrative one. The order book says they can sell it; the next four quarters decide whether they can build it fast enough to keep the margin.Doubling a manufacturing business in 12 months is hard. Doing it twice in a row is harder, and it will require capacity we are still building.
