LightPath Technologies (NASDAQ: LPTH) reported a robust fiscal fourth quarter, with revenue surging 73.8% year-over-year to $21.2 million, gross margin expanding to 39.4%, and adjusted EBITDA turning positive at $2.1 million. The results mark the company's strongest operating quarter in recent history, yet the stock closed Thursday at $9.68, down 4.5%, before inching up to around $9.76 in after-hours trading.
The market's muted reaction reflects lingering concerns about the quality and sustainability of the growth. Much of the revenue increase came from acquisitions, the company still posted a GAAP net loss, operating cash flow remains negative, and the share count has ballooned by 63% over the past year. While LightPath has demonstrated it can scale, investors are waiting for proof that this scale will translate into per-share value.
Quarterly and Annual Highlights
For the quarter ended June 30, gross profit more than tripled to $8.35 million from $2.69 million in the prior-year period. Gross margin jumped 17.4 percentage points, driven by a richer mix of assemblies, modules, and camera systems, improved factory utilization, and the absence of last year's inventory reserve. The net loss narrowed to $4.14 million, or $0.06 per share, from $7.06 million, or $0.16 per share, a year earlier. Adjusted EBITDA swung to positive $2.10 million from a loss of $1.98 million, marking the fourth consecutive quarter of positive adjusted EBITDA.
For the full fiscal year 2026, revenue climbed 92.7% to $71.72 million, gross margin improved to 36.0% from 27.2%, and adjusted EBITDA turned positive at $4.23 million versus a $5.06 million loss the prior year. However, the results include a full year of G5 Infrared (acquired in February 2025) and about five months of Amorphous Materials (AML). In the fourth quarter alone, AML contributed $1.1 million in infrared-materials sales, underscoring that the near-doubling of revenue is not purely organic.
Backlog and Order Momentum
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 over the next 12 months, which alone is 19% above all of fiscal 2026 revenue. The total backlog represents 1.55 times last year's sales, highlighting strong demand visibility. However, the backlog grew only marginally sequentially—from $110.6 million at the end of March—despite booking an $11 million follow-on infrared-camera order and $13 million of follow-on optical-assembly orders around quarter-end.
Investors will be watching whether the company can convert this backlog into revenue without sacrificing margins. A flat backlog while revenue grows can be healthy if new orders are replenishing shipments, but delivery schedules on defense programs can slip. The $85.6 million scheduled portion is not revenue guidance, and execution will be key.
Why the Stock Trades Below
Despite the operational improvements, several factors weigh on the stock. First, adjusted EBITDA has not yet translated into cash flow. LightPath used $10.23 million of cash in operations during fiscal 2026, up from $8.33 million a year earlier, as receivables and inventory rose by $5.58 million and $5.06 million, respectively. Capital expenditures also jumped to $6.27 million from $1.26 million, with plans for additional capacity in Florida, Texas, Latvia, and other U.S. sites.
Second, the company funded its growth through equity issuance. Public stock offerings generated $112.3 million in net proceeds during the year, and common shares outstanding rose to 69.96 million from 42.95 million. At Thursday's close of $9.68, the market capitalization is roughly $677 million, or about 9.4 times fiscal 2026 revenue. That is a rich valuation for a company that reported a $20.55 million GAAP net loss, even though $15.64 million of that was a noncash acquisition-earnout remeasurement.
Furthermore, the June primary offering was priced at $14 per share, and the stock now sits about 31% below that level. This illustrates the disconnect between operational progress and shareholder returns: the company raised the capital it needed, but the market has not rewarded the larger equity base.
What Could Change the Thesis
For bulls, the most significant catalyst would be a quarter where revenue growth, high-30s gross margin, and positive adjusted EBITDA translate into positive operating cash flow. That would demonstrate that the backlog is funding expansion rather than requiring more working capital. For bears, the risk is that capacity spending accelerates before customer schedules firm up, leading to further cash burn.
LightPath is also selling its China subsidiary for $4.5 million payable over five years, aligning manufacturing with U.S. and allied-country sourcing priorities. While strategically sensible, the deal introduces collection and transition risks and removes some China operation revenue from future consolidated results.
The after-hours reaction was restrained, with shares trading near $9.76, up about 0.8% from the regular close but still below Wednesday's $10.14 finish. Friday's trading will provide a clearer signal on how the market interprets the results. The earnings report validates the operational turnaround, but the investment case is not complete—conversion, cash flow, and share discipline will determine whether LPTH can finally break above $10.
