LightPath Technologies just delivered its best operating quarter in years, but the stock is still being valued as a prove-it story. Fiscal fourth-quarter revenue jumped 73.8% to $21.2 million, gross margin reached 39.4%, and adjusted EBITDA turned positive at $2.1 million. Yet LPTH closed Thursday at $9.68, down 4.5%, before edging up to about $9.76 in extended trading as of 6:18 p.m. ET.
The disconnect is not hard to explain. Much of the growth came from acquisitions, the company still lost money under GAAP, cash generation has not caught up with adjusted earnings, and the common-share count rose 63% in a year. LightPath now has enough demand and cash to scale; shareholders still need proof that the scale will translate into per-share value.
The quarter was better than the share reaction
LightPath’s unaudited fiscal 2026 results filed with the SEC show a real improvement beneath the headline. Fourth-quarter gross profit more than tripled to $8.35 million from $2.69 million. Gross margin expanded by 17.4 percentage points, helped by a richer mix of assemblies, modules and camera systems, better factory utilization, and the absence of last year’s extra inventory reserve.
The quarterly net loss narrowed to $4.14 million, or 6 cents a share, from $7.06 million, or 16 cents. The adjusted-EBITDA reconciliation is especially important: it shows positive $2.10 million, versus a $1.98 million loss a year earlier. That was LightPath’s fourth consecutive positive adjusted-EBITDA quarter.
Full-year revenue rose 92.7% to $71.72 million, while gross margin improved to 36.0% from 27.2%. Adjusted EBITDA swung to positive $4.23 million from a $5.06 million loss.
But the comparison is not purely organic. Fiscal 2026 included a full year of G5 Infrared, acquired in February 2025, and about five months of Amorphous Materials, or AML. In the fourth quarter alone, AML contributed $1.1 million of infrared-materials sales. Investors should therefore treat the near-doubling of annual revenue as evidence that the acquisitions added scale—not yet as proof that the underlying business can repeat a 93% growth rate.
The $110.9 million backlog is large—but it barely grew sequentially
LightPath ended June with a record $110.9 million order backlog, up 197% year over year. Of that, $85.6 million is scheduled for delivery in the next 12 months. The scheduled portion alone is 19% above all of fiscal 2026 revenue, while total backlog equals 1.55 times last year’s sales.
That is the bullish case in one number, but it needs context. Backlog was already $110.6 million at the end of March, according to the prior-quarter SEC exhibit. It increased by only about $300,000 sequentially even as LightPath booked an $11 million follow-on infrared-camera order and $13 million of follow-on optical-assembly orders around the quarter-end period.
A flat backlog while revenue rises can be healthy if shipments are being replenished by new awards. The next test is conversion: delivery schedules can move, particularly on defense programs, and the $85.6 million figure is not revenue guidance. A clean fiscal 2027 would show backlog turning into sales without sacrificing the high-30% gross margin achieved in the June quarter.
Why LPTH still trades below $10
First, adjusted EBITDA has not yet become cash. LightPath used $10.23 million of cash in operations during fiscal 2026, versus $8.33 million a year earlier. Receivables rose by $5.58 million and inventory by $5.06 million as the business expanded. Capital-equipment purchases also climbed to $6.27 million from $1.26 million, and management plans additional melting, optical and assembly capacity in Florida, Texas, Latvia and other U.S. sites.
Second, the balance-sheet transformation came from issuing equity. LightPath finished June with $93.2 million of cash and almost no conventional loan debt, but public stock offerings generated $112.3 million of net proceeds during the year. Common shares outstanding rose to 69.96 million from 42.95 million. The company also retains Series G convertible preferred stock and acquisition-related obligations.
At Thursday’s $9.68 regular close, the June 30 common-share count implies an equity value of roughly $677 million, or about 9.4 times fiscal 2026 revenue before considering further dilution. That is a demanding sales multiple for a company that posted a $20.55 million annual GAAP net loss, even though $15.64 million of that year’s operating expense came from noncash acquisition-earnout remeasurement.
The June primary offering also priced at $14 a share. LPTH now sits about 31% below that level, illustrating why operating progress can coexist with a weak stock: the company raised the capital it needs, but the market has not yet rewarded the larger equity base.
What would change the thesis
For bulls, the most consequential change would be a quarter in which revenue growth, high-30% gross margin and positive adjusted EBITDA produce positive operating cash flow. That would show that the $110.9 million backlog is funding the expansion rather than merely requiring more working capital.
For bears, the risk is that capacity spending rises before customer schedules firm up. LightPath is also selling its China subsidiary for $4.5 million payable over five years. The move aligns manufacturing with U.S. and allied-country sourcing priorities, but it introduces collection, transition and supply-continuity risks while removing some China operation revenue from future consolidated results.
The first after-hours response was restrained. LPTH traded near $9.76 at 6:18 p.m. ET, up about 0.8% from the regular close but still 3.7% below Wednesday’s $10.14 finish. Extended-hours quotes can be thin and volatile, so Friday’s volume and the market’s treatment of the $10 level will give a cleaner verdict.
The earnings report validates the operating turnaround. It does not finish the investment case. From here, conversion, cash flow and share discipline matter more than another record-backlog headline.
