Results from Operations

Third Quarter 2026

Revenue was $15.7 million for the three months ended September 30, 2026 compared with $14.2 million for the three months ended September 30, 2025. The increase was primarily due to strong growth in aerospace and defense, avionics, and space product shipments.

Gross margin was 44.5% for the three months ended September 30, 2026 compared with 44.3% for the three months ended September 30, 2025. The increase was primarily due to product mix.

Net income was $3.0 million, or $0.70 per diluted share, for the three months ended September 30, 2026 compared with $1.8 million, or $0.60 per diluted share, for the three months ended September 30, 2025. The increase was primarily due to the increase in gross margin discussed above and higher interest income earned on investments in money market mutual funds driven by higher balances invested.

The increase was partially offset by higher engineering, selling and administrative expenses driven by higher research and development investment, higher sales commissions consistent with the increase in revenues, higher stock-based compensation, and an increase in administrative and corporate expenses consistent with the overall growth in the business.

Adjusted EBITDA was $3.6 million for the three months ended September 30, 2026 compared with $3.2 million for the three months ended September 30, 2025. The slight increase was primarily due to higher revenues and gross profit partially offset by higher general and administrative expenses.

Fiscal Year to Date 2026

Revenue was $45.5 million for the nine months ended September 30, 2026 compared with $40.2 million for the nine months ended September 30, 2025. The 13.3% increase was primarily due to continued strong aerospace and defense and avionics product shipments.

Net income was $7.3 million, or $1.79 per diluted share, for the nine months ended September 30, 2026 compared with $5.0 million, or $1.64 per diluted share, for the nine months ended September 30, 2025. The increase was primarily due to higher revenues and gross profit as well as higher interest income earned partially offset by higher engineering, selling and administrative expenses driven by higher research and development investment, higher sales commissions consistent with the increase in revenues, $918 of stock-based compensation related to 2025 bonuses, and an increase in administrative and corporate expenses to support the growth in revenues.

Adjusted EBITDA was $10.2 million for the nine months ended September 30, 2026 compared with $8.1 million for the nine months ended September 30, 2025. The increase was primarily due to higher revenues and improved operating leverage.

Backlog

Backlog was $84.9 million as of September 30, 2026, an increase of 44.3% from $58.8 million as of September 30, 2025 and 11.0% from $76.4 million as of December 31, 2025. The increase in backlog reflects broad demand for our products including continued purchasing under several large aerospace and defense programs, the initiation of orders for new aerospace and defense programs, and a recent uptick in space industry orders.
