Justice Department Seeks More Information on MDA Takeover of SS/L

Richmond, BC (MDA PR) — MacDonald, Dettwiler and Associates Ltd., a provider of essential information solutions, announced that it has today received a request for additional information, often referred to as a “second request” from the U.S. Department of Justice (“DOJ”), in connection with MDA’s proposed acquisition of Space Systems/Loral Inc. (“SS/L”). A second request may be a part of the review process under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (“HSR Act”). The second request seeks additional information primarily regarding MDA’s Montreal satellite communications antenna and payload business.

The effect of the second request will be to extend the waiting period imposed by the HSR Act until 30 days after MDA has substantially complied with the second request.

MDA will continue to work closely and cooperatively with the DOJ as it conducts its review of the proposed transaction in order to respond to any questions the DOJ may have.
