Exhibit 99.1

M-tron Industries, Inc. Reports First Quarter 2026 Results

ORLANDO, Florida (May 7, 2026) — M-tron Industries, Inc. (NYSE American: MPTI) ("Mtron" or the "Company"), a U.S.-based designer and manufacturer of highly-engineered electronic components and solutions for the aerospace and defense, avionics, and space industries, announced its financial results for the three months ended March 31, 2026.

"Mtron delivered another quarter of record revenue, marking our fourth consecutive record quarter," said Cameron Pforr, Mtron Chief Executive Officer. "Our gross margins were also healthy due to higher revenues and continued focus on manufacturing efficiencies"

"We also successfully completed the rights offering on April 27, 2026, issuing 713,362 shares and strengthening our balance sheet with an additional $42.1 million of cash," continued Mr. Pforr. "This puts us in a great position to execute as we navigate the opportunities arising in the defense sector."

Results from Operations

Revenue was $14.7 million in the first quarter of 2026 compared with $12.7 million in the first quarter of 2025. The increase was primarily due to strong defense product shipments as well as higher avionics sector shipments.

Gross margin was 44.9% in the first quarter of 2026 compared with 42.5% in the first quarter of 2025. The increase is primarily due to higher revenues, product mix, and manufacturing efficiencies.

Net income was $2.4 million, or $0.67 per diluted share, in the first quarter of 2026 compared with $1.6 million, or $0.56 per diluted share, in the first quarter of 2025. The increase in revenues discussed above, manufacturing efficiencies, and higher interest income partially offset by higher engineering, selling and administrative expenses related to higher research and development costs, higher sales commissions from an increase in revenues, and an increase in corporate expenses consistent with the overall growth in the business.

Adjusted EBITDA was $3.2 million in the first quarter of 2026 compared with $2.5 million in the first quarter of 2025. The increase was primarily due to the increase in revenues discussed above and improved gross margins.

Backlog

Backlog was $76.8 million as of March 31, 2026 compared to $76.4 million as of December 31, 2025 and $55.5 million as of March 31, 2025. The increase in backlog is primarily driven by orders in the aerospace and defense, avionics, and space sectors.
