OSI Systems announced a $235 million Undefinitized Contract Action (UCA) for the production and integration of a homeland defense over‑the‑horizon radar (OTHR) transmit subsystem, a project that will enable long‑range tracking of various target types beyond conventional line‑of‑sight limitations.

The UCA, with a not‑to‑exceed value of approximately $235 million, is initially funded with $46 million and will be delivered under a phased execution framework that includes performance‑based milestones, allowing the company to scale the program as requirements evolve.

The award represents roughly 13% of OSI’s $1.8 billion annual revenue and adds a significant new revenue stream to the Security division, which grew 60% year‑over‑year in Q3 FY24. The contract underscores the division’s continued success in securing high‑value defense contracts and positions OSI to capture additional opportunities in homeland security and defense markets.

"This award highlights our strengths in critical radio frequency engineering, advanced manufacturing, and complex system integration for mission‑critical defense applications. We are proud to support a next‑generation sensing program designed to enable reliable, long‑range performance in demanding operational environments," said Ajay Mehra, President and Chief Executive Officer of OSI Systems.

Analysts maintain a strong‑buy consensus for OSI, with 7 analysts issuing a strong‑buy rating and 71% recommending a strong buy. The average 12‑month price target ranges from $301.29 to $308.40, with high estimates up to $345.00 and low estimates around $262.00. The company’s stock has delivered a 51% return over the past year and a 54.82% total shareholder return over the same period, reflecting investor confidence in its growth trajectory.

The contract strengthens OSI’s backlog and enhances its competitive position in the defense sector. While execution risk and potential cost inflation remain headwinds, the award signals robust demand for advanced RF and system‑integration capabilities and positions OSI to capitalize on future defense opportunities.
