nLIGHT Earnings Call: Defense Strength, Margins Surge

Nlight ((LASR)) has held its Q1 earnings call. Read on for the main highlights of the call.

nLIGHT’s latest earnings call painted a notably upbeat picture, with management emphasizing robust growth, expanding margins and a much stronger balance sheet. Revenue jumped 55% year over year, product gross margins hit record levels and adjusted EBITDA surged, while recent capital raising further bolstered liquidity. Challenges around development margins, program timing and end-market transitions were acknowledged but framed as manageable against the broader momentum.

Strong Top-Line Growth

nLIGHT reported total revenue of $80.2 million, up 55% from $51.7 million a year earlier, reflecting powerful momentum across its core franchises. Sequentially, sales were essentially flat, down just 1% versus the prior quarter, as strength in aerospace and defense and solid commercial demand offset normal quarter-to-quarter variability.

Aerospace & Defense Outperformance

Aerospace and defense remained the engine of growth, with A&D revenue reaching $55.1 million, a 69% year-over-year increase. Within that, A&D product revenue surged 98% versus last year and climbed 10% sequentially, cementing its role as the primary driver of both overall expansion and margin improvement.

Record Product Gross Margins

Product gross margin reached a record 43.6% on a GAAP basis and 44.6% on a non-GAAP basis, a sharp rise from 33.5% a year ago. Management credited a favorable product and customer mix, combined with higher production volumes, which together boosted factory utilization and profitability.

Improved Profitability and Adjusted EBITDA

Profitability metrics improved dramatically, with adjusted EBITDA hitting a quarterly record of $13.9 million versus just $0.116 million in the prior-year period. Non-GAAP net income reached $11.8 million, or $0.20 per share, swinging from a non-GAAP net loss of $1.9 million last year and highlighting the leverage in the model as revenue scales.

GAAP Profitability and Cash Generation

On a GAAP basis, nLIGHT returned to profitability with net income of $0.645 million, or $0.01 per diluted share, versus an $8.1 million loss a year ago. Operating cash flow of $9.7 million and an improvement in cash flow conversion days to 97 from 125 underscored better working-capital management and the cash-generative nature of the current mix.

Balance Sheet Strengthened by Equity Raise

The company further fortified its balance sheet by completing a follow-on equity offering in February, raising more than $190 million after fees. As a result, total cash, cash equivalents, restricted cash and investments climbed to $332.9 million, giving nLIGHT ample financial flexibility to fund growth initiatives and navigate end-market volatility.

Strategic Product and Program Milestones

Management highlighted strategic progress in high-energy laser programs, including the launch of the Hades portfolio of scalable beam-combined lasers with integrated atmospheric correction. The company remains on track under HELSI 2 for one-megawatt-class work and is advancing the Navy’s HELL CAP effort, which targets combining a 300-kilowatt beam with adaptive optics.

Commercial Market Upside

Commercial revenue reached roughly $25 million, up 32% year over year, offering a complementary growth leg alongside defense. Microfabrication revenue of around $13 million slightly exceeded expectations, while approximately $12 million in industrial revenue was aided by additive manufacturing demand and last-time buys from customers.

Operational Discipline and Cost Control

This was the fifth consecutive quarter of product revenue growth, showing consistency despite program-driven lumpiness. Non-GAAP operating expenses fell to $17.1 million from $17.8 million a year earlier, as management kept tight control on spending even while investing in key programs and capabilities.

Pressure on Development Gross Margins

Not all trends were favorable, as development gross margin slid to 5.1% on a GAAP basis and 7.2% non-GAAP, down from 11.5% in the prior-year quarter. The decline reflected contract mix and the timing of program milestones, signaling that development profitability can fluctuate meaningfully depending on where major projects sit in their lifecycle.

Development Revenue Volatility

Development revenue reached $22 million, up 38% year over year but down 16% sequentially, illustrating the inherent volatility in this line. The quarterly drop mainly reflected the successful delivery of a 50-kilowatt DEM shorehead in 2025 and the timing of work under HELSI 2, which shifted revenue out of the current period.

Higher GAAP Operating Expenses

GAAP operating expenses rose to $27.2 million from $23.4 million a year earlier, driven largely by higher stock-based compensation tied to the company’s growth phase. However, the reduction in non-GAAP operating expenses indicates that underlying cost discipline remains intact even as nLIGHT uses equity-based incentives to retain key talent.

Exit from Legacy Cutting and Welding

nLIGHT is exiting its legacy cutting and welding markets and expects minimal revenue from those segments after the second quarter, a move that will create a near-term headwind for industrial sales. Management framed the decision as a strategic shift away from lower-return legacy applications toward higher-value defense, microfabrication and advanced industrial opportunities.

Revenue Concentration and Program Timing Risk

The company acknowledged that its heavy reliance on aerospace and defense programs and U.S. government funding introduces timing and concentration risk. While the latest federal budget signals increased spending in relevant areas, the appropriation process remains uncertain and could create periods of lumpiness in nLIGHT’s revenue trajectory.

Margin Variability Ahead

Management cautioned that product margins may remain variable quarter to quarter, given their sensitivity to volumes, mix and factory absorption. The guidance range for product gross margin of 37% to 41% suggests potential swings of several hundred basis points, a reminder that profitability can move with shifts in demand and program schedules.

Guidance and Forward Outlook

For the second quarter of 2026, nLIGHT guided revenue to $75 million to $81 million, with about $58 million from products and $20 million from development, assuming sequential growth in A&D. The company expects overall gross margin of 29% to 33%, product gross margin of 37% to 41%, development gross margin near 8% and adjusted EBITDA of $8 million to $12 million, while keeping non-GAAP operating expenses in the $17 million to $19 million range.

nLIGHT’s earnings call showcased a company leaning into its strengths, with A&D and high-energy laser platforms driving growth, margin expansion and improved cash generation. While exposure to government programs, development volatility and the industrial transition present risks, management’s disciplined execution, strengthened balance sheet and clear strategic focus position the company as a compelling, though still cyclical, play for investors tracking advanced photonics and defense technologies.
