LightPath Technologies (LPTH) Q1 2027 earnings review
LightPath's unfilled orders rose 20%, but its cash fell 11%
LightPath, a maker of infrared lenses and thermal cameras for defence customers, won far more orders than it shipped. Unfilled orders rose 20% in three months to a record $133 million, chief executive Sam Rubin said. Revenue climbed 38% from a year ago, but it slipped slightly from the prior quarter.
| Sales growth without the January acquisition (by our math) | +31% +38% as reported, to $20.8M |
|---|---|
| Unfilled orders (backlog) | $132.9M +20% from last quarter; +54% from a year ago |
| Gross margin | 41.4% 29.8% a year ago |
| Orders due within 12 months | $110.8M $85.6M in June; LightPath gives no sales forecast |
⚖️ Verdict: 🟢 Bullish
The story got better because orders outran shipments again, after a quarter in which the two had only matched. A richer product mix also pushed gross margin above 41%. One caution: LightPath spent about $11 million of cash, mostly on materials for products it has not yet delivered.
The question now is whether LightPath can turn those orders into deliveries on time. If it can, the materials become sales within a year; if it cannot, cash keeps leaving while revenue stands still. Next quarter's revenue and inventory will tell.
🐂 Bull Case
Cameras and Assemblies Lifted Gross Margin Past 41%
LightPath sells loose lenses and also complete products built from them. It calls the second group assemblies and modules: thermal cameras and lens units ready for a customer's system. The release said these are the products "which typically earn higher margins".
That group brought in $10.5 million this quarter, up 76% from a year ago. G5 Infrared, the camera maker LightPath bought in 2025, sold more cameras for surveillance and drone detection, the company said.
- Assemblies and modules: 51% of revenue, up from 40% a year ago
- Gross margin: 41.4%, against 29.8% a year ago
- Gross margin last quarter: 39.4%
- Cost of making the products: 58.6% of revenue, down 11.7 percentage points
This matters because gross profit almost doubled while revenue rose 38%. Chief executive Sam Rubin credited the shift to "higher-value cameras and optical assemblies". The margin has now climbed for two quarters in a row, so the gain does not rest on one large shipment.
What to watch: the share of revenue from assemblies and modules next quarter. A share near half would show the margin gain comes from what LightPath sells, not from one order's timing.
Customers Ordered Twice What LightPath Shipped
LightPath gives no sales forecast, so its backlog is the best view of future revenue. Backlog is the value of orders that customers have placed but not yet received. Rubin said new orders "significantly outpaced shipments during the first quarter".
By our math, customers placed about $43 million of new orders, roughly twice the $20.8 million LightPath shipped. A quarter earlier the two figures had only matched. Most of the named orders were cameras and lens units for systems that detect and track drones.
What to watch: backlog at the end of December, which LightPath reports with its next results. A second quarterly rise would show that the earlier pause was a matter of timing.
LightPath Left China and Won US Government Funding
A US law passed in December 2025 directs the defence department to stop relying on certain foreign nations for optical glass by 2030. LightPath makes BlackDiamond, a glass that replaces germanium, a metal whose exports China has curbed.
The company completed the sale of its Chinese subsidiary on October 30 and "no longer has facilities or operations based in China". The Department of War awarded it a funded prototype agreement to develop BlackDiamond for defence infrared systems.
Rubin called the award "direct government support for the materials at the center of our platform". But LightPath disclosed no dollar amount, so the award adds nothing to revenue yet.
What to watch: a dollar value for the agreement or a first production order. Either would show government support turning into sales.
🐻 Bear Case
Inventory Rose 75% While Shipments Slipped
"Our focus for the balance of fiscal 2027 is converting this backlog on schedule," chief executive Sam Rubin said. The first quarter did not show that yet. Revenue slipped 2% from the prior three months, even as unfilled orders reached a record.
Instead LightPath prepared. Rubin said the company "invested ahead of scheduled deliveries", buying critical materials and adding manufacturing capacity. It also appointed Scott Payette, a former Anduril production leader, to run its camera unit. LightPath needs that capacity to fill its orders. But the cash left before the sales arrived.
- Inventory: $31.5 million, up 75% in three months
- Inventory as a share of the quarter's revenue: 152%, against 85% in June
- Cash used in operations: $8.3 million, against $1.1 million a year ago
Inventory only pays off when LightPath ships it. Customers have asked for about $111 million of deliveries within twelve months. By our math that requires about $28 million of revenue a quarter, a third above what it just delivered.
What to watch: revenue and inventory next quarter. Revenue near $28 million with a smaller inventory would show that the materials are becoming shipments.
Costs Grew Faster Than Gross Profit
Rubin pointed to "positive adjusted EBITDA for the fifth consecutive quarter". The measure leaves out interest, tax, depreciation and other items, such as pay in shares. It fell to $1.3 million from $2.1 million last quarter.
The reason is spending. Gross profit rose $4.1 million from a year ago, but selling, administrative and product development costs climbed $4.8 million. Share-based pay reached $1.8 million, above the adjusted profit.
- Selling and administrative costs: 38.8% of revenue, up 9.7 percentage points
- New product development: 9.8% of revenue, up 4.0 percentage points
- Operating loss before the acquisition payout charge: $2.0 million, against $1.2 million, by our math
What to watch: selling and administrative costs as a share of revenue. A share near 39% without revenue growth would keep shrinking the adjusted profit.
Two Customers Placed Most of the New Orders
One customer supplied 24% of LightPath's revenue last fiscal year. A second worry was that orders had stopped outrunning shipments. This quarter answered the second worry, but the answer came from familiar buyers.
A supplier of counter-drone systems ordered more than $19 million of lens units between July and October. LightPath said that is "double that customer's total for all of fiscal 2026". A "leading global technology customer" added an $11 million camera order.
By our math, these two buyers placed at least 56% of the orders booked this quarter. Rubin named large defence programmes as a third growth area, but the release listed no new order there.
What to watch: the largest customer's share of revenue in the next annual report. A share above 24% would mean deeper dependence.
Risks this quarter didn't answer
Six standing concerns got no new numbers in the press release or in the November investor presentation that came with it.
- Lockheed Martin air-defence programme: the presentation still lists a 50% win probability and first low-volume production in 2027; a contract award would settle it.
- Surveillance towers: the presentation lists $20 million of potential 2026 bookings with Elbit Systems of America; the release named no such order.
- Germanium supply: no update on Chinese export limits; freer supply would reduce the pressure on customers to switch to BlackDiamond glass.
- Cooled camera redesign: the presentation still labels the move to BlackDiamond glass "Redesign Underway"; a first shipment would move it.
- Sensor supply: no figure on lead times for the detectors inside cooled cameras; the quarterly filing's inventory breakdown will show what LightPath bought ahead.
- Share sales and acquisitions: LightPath sold no new shares for cash this quarter; the final payout to G5 Infrared's sellers falls due in January 2027.
👓 Other Themes
Armies Are Buying Drones in Large Numbers
In October a defence customer ordered more than 50,000 lens units for drone cameras. LightPath said the order came "as the U.S. and its allies rapidly scale up drone procurement". The release gave no dollar value or delivery schedule, so nobody outside the company can yet measure the order's effect on revenue.
💲 Other KPIs
Spending on plant and equipment eased from $4.4 million last quarter, by our math, but stayed far above $0.1 million a year ago. It equalled 12% of revenue. LightPath said most of the money expanded manufacturing capacity, including glass fabrication. A sale and leaseback of equipment returned $0.6 million.
Sales of loose infrared lenses rose 15% from a year ago, but only because of Amorphous Materials, a glass maker LightPath bought in January. By our math, the line shrank about 12% without it. LightPath cited lower sales to European defence customers "due to timing of orders". The line had brought in $7.1 million last quarter.
The average share count rose 62% from a year ago after two public share sales and the conversion of preferred stock. More shares divide any future profit among more owners. LightPath sold no new shares for cash this quarter, and the count at the end of September was 70.1 million.
🔮 Guidance
Raised. LightPath gives no sales forecast, but customers have asked for $110.8 million of deliveries by next September. By our math that averages $27.7 million a quarter, 33% above this quarter's revenue. The pace of recent quarters would not get there. LightPath turned about 19% of opening backlog into revenue in each one, and this schedule needs about 21%.
Unchanged. The November investor presentation repeats the goal of annual revenue above $300 million in five years. By our math that needs growth of about 33% a year from fiscal 2026's $71.7 million. This quarter's reported growth cleared that pace. Growth without the January acquisition, about 31%, fell just short.
❓ Key Questions
How much of the backlog comes from two customers?
Two buyers placed most of the new orders this quarter. One customer supplied 24% of revenue last fiscal year. A backlog split by customer would show how much of the next twelve months depends on them.
What is the backlog split by product group?
Cameras and assemblies earn higher margins than loose lenses. The mix inside the $132.9 million backlog would show whether gross margin can stay above 41% as LightPath ships it.
How much will LightPath spend on capacity this fiscal year?
The company spent $2.5 million on plant and equipment this quarter and gave no budget for the year. A dollar figure would let investors judge how long $82.9 million of cash will last.
How much revenue and profit left with the Chinese unit?
LightPath sold the subsidiary for $4.5 million, payable over five years, and keeps a supply relationship with it. The release gave no revenue or profit figure for the unit, and it flags a risk that the buyer does not pay.
When will the cooled cameras ship with BlackDiamond glass?
LightPath aimed to finish the redesign of G5 Infrared's cooled cameras in summer 2026. The November presentation still shows the work as under way. Until it finishes, those cameras depend on germanium.
