Here's How the Test Systems Segment Powers Astronics' Growth Story

Astronics Corporation’s ATRO Test Systems segment is gradually emerging as an important contributor to the company’s long-term growth, positioning it to benefit from structural expansion in aerospace, defense modernization and advanced electronics testing. In 2025, the segment accounted for 7.5% of total revenues and ended the year with a backlog of $74 million, reflecting a 19.5% year-over-year increase and indicating solid demand visibility.

The Test Systems business focuses on designing, developing, manufacturing, and maintaining automated test systems that support the aerospace and defense as well as mass transit industries. Its solutions are sold to a global customer base that includes original equipment manufacturers (OEMs) and prime government contractors involved in both commercial electronics and military programs.

In 2025, the segment generated $35.4 million in revenues from the aerospace and defense market, $5.3 million from the mass transit market, and $24.1 million from the radio test market. These diversified end markets provide Astronics with exposure to multiple technology-driven sectors.
Growing government investments in next-generation defense platforms and space technologies are expected to further strengthen demand for advanced testing capabilities and position Astronics’ test systems to benefit.

The segment also benefits from a recurring revenue profile. Once its test solutions are deployed in a program, customers require ongoing support ensuring predictable revenue streams.

By serving aerospace, defense, and other advanced electronics markets, the Test Systems segment also enhances Astronics’ business diversification. Overall, strong industry tailwinds, technological expertise, and lifecycle service revenues make this segment a key pillar of Astronics’ growth strategy.
