nLIGHT Q2 2026 earnings: Product revenue drives a record quarter

nLIGHT (NASDAQ: LASR) reported Q2 2026 revenue of $82.6 million, up 33.8% year over year, while its GAAP diluted loss per share narrowed to $0.02 from $0.07 for the quarter ended June 30, 2026. Products revenue reached a record $59.4 million, and adjusted EBITDA nearly doubled to $10.7 million. The main near-term issue is a supply-chain delay that shifted approximately $17 million of expected product shipments from Q3 into future quarters.

Core financial results

Products generated most of the quarter’s revenue increase, while an improved Products gross margin lifted the companywide gross margin by 1.2 percentage points. Operating expenses also increased, leaving nLIGHT with a GAAP operating loss despite the higher revenue and gross profit.

The gap between GAAP results and adjusted EBITDA remained significant, largely because adjusted EBITDA excludes stock-based compensation and other specified items.

Business and end-market performance

Products revenue increased much faster than Development revenue and accounted for most of nLIGHT’s overall growth. By end market, Aerospace and Defense remained the largest business and contributed the biggest dollar increase.

Products gross margin rose to 41.2% from 38.5%. Development gross margin moved in the opposite direction, falling to 5.6% from 13.1%, but the faster growth and higher profitability of Products supported the improvement in the consolidated margin.

Profitability, cash flow, and balance sheet

Total operating expenses increased approximately 29% to $29.3 million. Research and development expense rose to $13.1 million from $11.0 million, while sales, general, and administrative expense increased to $16.2 million from $11.7 million. Quarterly stock-based compensation climbed to $11.0 million from $6.4 million, contributing to the continued GAAP loss and accounting for a substantial adjustment in the company’s non-GAAP results.

Cash flow figures were provided for the six months ended June 30 rather than for Q2 alone. Six-month operating cash flow was $30.4 million, compared with a $1.4 million outflow in the prior-year period. After $7.0 million of capital expenditures, approximate six-month free cash flow was $23.5 million. Operating cash flow benefited from $21.8 million of non-cash stock compensation, a $9.2 million increase in deferred revenue, and collections of accounts receivable.

Cash and cash equivalents reached $295.8 million at June 30, up from $98.7 million at the end of 2025. The increase primarily reflected financing activity, including $192.2 million of public-offering proceeds. nLIGHT also repaid its $20.0 million line of credit, leaving no balance outstanding at quarter-end, and held another $34.7 million in marketable securities.

Delayed product shipments weaken both Q3 revenue and mix

The supply-chain issue affects more than the timing of revenue. Products carried a 41.2% gross margin in Q2, compared with only 5.6% for Development. Because the approximately $17 million delayed from Q3 consists of product revenue, its absence reduces both expected revenue and the contribution from nLIGHT’s higher-margin stream.

For Q3, the company expects approximately $43 million of Products revenue and $25 million of Advanced Development revenue. It also projects a Products gross margin of 34% to 40% and an Advanced Development gross margin of about 8%, resulting in a lower overall gross-margin range of 24% to 30%.

Guidance

nLIGHT expects the delayed product shipments to be delivered in future quarters, but it did not specify the timing beyond that statement. Q3 adjusted EBITDA guidance of $1 million to $7 million is also below the $10.7 million generated in Q2, consistent with the lower revenue and less favorable mix.

The release describes $70 million as the revenue midpoint, although the arithmetic midpoint of the stated $63 million-to-$73 million range is $68 million. The two disclosed revenue components also add to approximately $68 million.

Management perspective

Chairman and CEO Scott Keeney attributed the quarter’s performance to defense and advanced manufacturing demand. He said nLIGHT’s directed-energy pipeline continues to expand and identified the Joint Laser Weapon Systems contract as its latest example. Management also reported growing opportunities in laser sensing and advanced manufacturing, although it did not provide additional quantitative forecasts for those opportunities.

Recent insider transactions

The supplied insider data reports net insider selling of 93,121 shares over the past six months. Over the past two years, insiders purchased 498,104 shares across 12 transactions and sold 563,191 shares across 16 transactions, producing net sales of 65,087 shares.

Among the 10 most recent entries, six were zero-price director stock grants and four were direct sales with reported values totaling approximately $8.83 million. These transactions are presented without inferring insiders’ views of the company’s prospects.

Risks investors should watch

• Supply-chain execution: Approximately $17 million of expected Q3 product revenue has shifted into future quarters. Further delays would affect shipment timing, revenue, and adjusted EBITDA.
• Less favorable revenue mix: Development carries a much lower gross margin than Products. The expected Q3 mix helps explain why overall gross-margin guidance is below the Q2 result.
• GAAP profitability remains unresolved: nLIGHT narrowed its losses, but operating expenses and stock-based compensation continued to rise, and the company remained unprofitable under GAAP.
• Aerospace and Defense exposure: This end market represented approximately 69% of Q2 revenue. The concentration makes results sensitive to the timing and execution of defense-related programs.

Summary

nLIGHT’s record Q2 revenue was driven primarily by Products and Aerospace and Defense, with the higher-margin Products business also supporting better consolidated profitability. GAAP losses narrowed and six-month cash flow improved, while an equity offering materially strengthened the balance sheet. The central issue for the next quarter is whether nLIGHT can resolve supply-chain constraints, deliver the deferred product revenue, and restore a more favorable product mix while controlling operating expenses.
