ORLANDO, Florida (August 12, 2026) — M-tron Industries, Inc.

Results from Operations

Second Quarter 2026

Revenue was $15.1 million for the three months ended June 30, 2026 compared with $13.3 million for the three months ended June 30, 2025. The increase was primarily due to continued strong aerospace and defense program shipments and quarter over quarter growth for both avionics and space product shipments.

Gross margin was 41.2% for the three months ended June 30, 2026 compared with 43.6% for the three months ended June 30, 2025. The decrease reflects the impact of approximately $0.5 million of stock-based compensation recorded in Manufacturing cost of sales in connection with the 2025 bonus awards, a 3.1% impact to gross margin. This charge is not expected to recur at comparable levels in future periods. There was no such stock-based compensation in the three months ended June 30, 2025 for the 2024 bonus award.

Net income was $1.9 million, or $0.43 per diluted share, for the three months ended June 30, 2026 compared with $1.6 million, or $0.53 per diluted share, for the three months ended June 30, 2025. Current period results include $1.0 million of non-cash stock-based compensation expense associated with the accelerated vesting of the 2025 bonus award. This charge is not expected to recur at comparable levels in future periods. The decrease in diluted earnings per share is due to the increase in weighted shares outstanding related to the rights offering that was completed in April 2026.

Adjusted EBITDA was $3.4 million for the three months ended June 30, 2026 compared with $2.4 million for the three months ended June 30, 2025. The increase was primarily due to higher revenues partially offset by an increase in engineering, selling and administrative expenses.

Fiscal Year to Date 2026

Revenue was $29.8 million for the six months ended June 30, 2026 compared with $26.0 million for the six months ended June 30, 2025. The increase was primarily due to continued strong aerospace and defense program shipments as well as year-over-year growth in avionics product shipments.

Net income was $4.3 million, or $1.07 per diluted share, for the six months ended June 30, 2026 compared with $3.2 million, or $1.09 per diluted share, for the six months ended June 30, 2025. This reflects $1.0 million of non-cash stock compensation associated with the accelerated vesting of the 2025 bonus award. The increase in net income was driven by higher shipments partially offset by an increase in overall operating expenses, which grew at a slower rate than revenues. The decrease in earnings per diluted share was primarily due to the increase in weighted shares outstanding related to the rights offering completed in April 2026.

Adjusted EBITDA was $6.6 million for the six months ended June 30, 2026 compared with $4.9 million for the six months ended June 30, 2025. The increase was primarily due to higher revenues partially offset by an increase in engineering, selling and administrative expenses.

Backlog

Backlog was $84.0 million as of June 30, 2026 compared to $76.4 million as of December 31, 2025 and $61.2 million as of June 30, 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 avionics and space industry orders.

Strategic Investment

During the quarter, the Company made a small investment in a synchronization and timing systems company Skyline Instruments, LLC, which is making significant advancements critical for the synchronization of RF sensor data and operations in GPS denied environments. This is part of the Company’s effort to continue to innovate and learn about future market opportunities in areas critical to our national defense.
