Sparton said Monday it plans to resume negotiations with parties that previously showed interest in an acquisition deal and can immediately execute such a transaction.
The U.S. Navy suggested that Sparton and Ultra should independently build and market their sonobuoys and strive to end their use of ERAPSCO for such efforts.
ERAPSCO a joint venture of Sparton and Ultra Electronics has been producing sonobuoys and transducers for the Navy since 1987.
Ultra agreed to buy Sparton in July 2017 through a stock transaction valued at $23.50 per share.
