Comtech Telecommunications Corp. (NASDAQ: CMTL), a leading global provider of next-generation 911 emergency systems and secure wireless communications technologies, announced today that, in keeping with generational renewal cycles occurring across its core businesses, Comtech has established two business units focused on exploiting long-term and growing business opportunities in the satellite ground station market.

These two new business units, each of which will have its own agile and nimble business structure, will formalize and improve Comtech’s ability to serve U.S. and allied governments as a defense contractor and will facilitate the establishment of a major innovation center for Comtech’s growing commercial very-small aperture terminal (“VSAT”) platforms based in Canada. Daniel Gizinski and Dr. Vagan Shakhgildian have been appointed Presidents of two recently created U.S. and Canadian-based subsidiaries, respectively.

“Our customers expect Comtech to apply expertise and state-of-the-art technology to address their complex challenges,” said Comtech Chief Executive Officer and President Michael Porcelain. “This is especially the case for satellite and defense-related hardware and government contracts, both in the VSAT arena and more broadly. This organizational shift is the latest example of how Comtech is transforming itself to anticipate and meet the changing needs of our end markets. I congratulate both Daniel and Vagan for taking on these new roles and share a sense of momentum as we move toward a very bright future.”
