Defense lasers gain ground, but supply chains bite

01 Running thesis

A defense pivot with proof and hurdles

nLIGHT has made a sharp turn toward aerospace and defense. Q2 2026 gave clear proof of long-term viability, with defense revenue hitting a record $57.3 million. The company won a Joint Laser Weapon System contract with a ceiling over $600 million, securing a revenue bridge as older programs finish.

The bull case is simple. nLIGHT is leaving weaker cutting and welding work and putting energy into directed energy lasers. These high-power systems allow defense customers to track, disable, or destroy targets. The new contract confirms nLIGHT is moving from a parts supplier to a prime-level partner for production-ready laser weapons.

The company generated $9.7 million of cash from operations in Q1 2026, followed by record defense numbers in Q2. The launch of HADES, a high-energy laser family with built-in atmospheric correction, is central to this growth. A stronger balance sheet provides runway to expand capacity.

The bear case remains tied to concentration and supply chains. A more defense-heavy nLIGHT relies on few customers. If one major program slips or budgets move, revenue falls. Adding to this risk, Chinese supply chain bottlenecks recently pushed $17 million of expected revenue out of Q3 2026. The balance sheet is strong, but valuation is still a hard part of the story.

Aug 2026Q2 2026 brought record defense revenue and a $600 million ceiling contract win. However, supply chain limits pushed $17 million in expected revenue out of the third quarter, keeping the near-term outlook mixed.
May 2026Q1 2026 showed the defense pivot is still gaining speed. Defense revenue grew 68.6 percent year over year, product gross margin reached 43.6 percent, and operating cash flow was positive.
May 2026Management reported $80 million of Q1 revenue, record product gross margin of about 44 percent, and adjusted EBITDA of $14 million. It also launched the HADES directed energy portfolio.
Feb 2026The 2025 10-K confirmed the sharper defense mix and the rising concentration risk. Defense became 67 percent of 2025 revenue, while the top ten customers accounted for about 75 percent of revenue.
Feb 2026nLIGHT chose to exit cutting and welding and focus resources on defense, sensing, and additive manufacturing. The company also raised over $190 million after expenses, lowering balance sheet risk.
Nov 2025The Q3 2025 filing backed up the defense growth story and showed ongoing weakness in Industrial. It also added more detail on tariff and China-related risk.
Nov 2025Q3 2025 strengthened the bull case with record defense revenue and product gross margin of 41 percent. Management also said the expected HELSI-2 revenue gap was already filled by other booked business.
Aug 2025The Q2 2025 filing confirmed that defense had grown to 65.9 percent of revenue. Higher defense mix and volume helped expand Laser Products gross margin.
02 Business model

Built inside, sold to few buyers

nLIGHT designs and makes high-power semiconductor lasers, fiber lasers, fiber amplifiers, and related laser systems. It is vertically integrated, meaning it makes many key parts itself instead of buying them from outside suppliers. This can speed up design changes, control costs, and protect know-how.

The company makes money in two main ways. Laser Products sells hardware, such as semiconductor lasers and directed energy laser products. Advanced Development earns revenue from research and development contracts, mostly tied to defense programs.

The model works best when product volume rises and factory costs spread across more units. It breaks when big customers delay awards, development contracts carry lower margins, or supply chains fail. Supply chain limits recently forced nLIGHT to delay product shipments, showing vulnerability to outside bottlenecks.

Management is narrowing the company on purpose. It is exiting cutting and welding, freeing people and capital for directed energy, laser sensing, and additive manufacturing. This focus is meant to build a more profitable core.

03 Product portfolio

Lasers for force and precision

Growth engine

Directed energy laser products

These high-power products are the center of the defense pivot. Record Q2 2026 revenue was driven by a 72 percent jump in defense product sales.

Option

HADES high-energy laser portfolio

HADES stands for High-energy laser with Atmospheric Distortion-correction and Electro-optic System. It is a new family of scalable high-energy lasers for the directed energy market.

Option

Advanced development contracts

These are paid research and development contracts, mainly for defense laser technology. They can open doors to later product sales, but margins can be lower and more uneven.

Steady

Fiber lasers and amplifiers

These products serve industrial, microfabrication, and defense uses. They are part of the base technology that lets nLIGHT sell both components and complete laser solutions.

Steady

Microfabrication lasers

Microfabrication uses lasers for precise processing. This market provides stable commercial revenue outside of the defense focus.

Steady

Additive manufacturing fiber lasers

This is the healthier part of the remaining industrial business, offering a growth area beyond legacy cutting and welding.

The revenue mix is based on Q1 2026 end-market disclosure, showing defense as the clear majority.

05 Risk factors

What could break the pivot

Supply chain bottlenecks

High impact · High odds

nLIGHT depends on foreign suppliers for components like dual-use optics. Recent restrictions in China forced the company to delay about $17 million in third-quarter revenue. If supply chains are not fixed quickly, these issues could hurt defense delivery timelines.

We watchWatch for updates on qualifying new optics suppliers and recapturing the delayed $17 million.

A&D customer concentration

High impact · Medium odds

nLIGHT depends on a small group of customers. In 2025, the top ten customers accounted for about 75 percent of revenue. A lost customer, a paused order, or a smaller follow-on award could hit revenue and factory usage fast.

We watchTrack the top ten customer share and any disclosure of delayed or reduced defense orders.

Government program timing

High impact · Medium odds

Defense work can move in chunks. Awards, prototypes, and production ramps depend on budgets and program choices that nLIGHT does not control. A strong quarter may not repeat if a large program slips into a later period.

We watchWatch new defense program wins and the timing of Joint Laser Weapon System revenue.

HADES ramp uncertainty

Medium impact · Medium odds

HADES could make nLIGHT a more important system supplier in directed energy. But the company has not yet proven the product line's revenue size or margin profile. If adoption is slow, investor hopes may run ahead of the business.

We watchLook for named HADES orders, funded tests, and management comments on margins.

Commercial reset takes longer

Medium impact · Medium odds

nLIGHT is exiting cutting and welding after weak industrial demand. Management expects a $25 million to $30 million full-year revenue headwind in 2026 from that choice. The remaining industrial base still needs to prove its normal growth rate.

We watchWatch Industrial revenue after the cutting and welding exit is complete.
06 Quick answers

In one breath

What does nLIGHT do?

nLIGHT makes high-power lasers and laser systems. Its products are used in defense, microfabrication, industrial processing, and research and development programs.

Why is nLIGHT becoming a defense company?

Aerospace and defense is now the largest and fastest-growing part of the business, backed by large contracts like a $600 million ceiling award. The company is actively exiting lower-margin industrial markets to focus on defense.

What is HADES?

HADES is nLIGHT's new portfolio of scalable high-energy lasers with atmospheric correction. It is meant to keep a powerful laser aimed and useful even when air conditions distort the beam.

What is the biggest risk for LASR stock?

The biggest risks are customer concentration and supply chain vulnerability. Growth depends on a small number of defense buyers, and recent parts shortages have delayed millions in expected revenue.
