The Excalibur Automobile Company, founded by American designer Brooks Stevens and run by his sons, was experiencing financial difficulties. The ASE certified auto manufacturer was purchased by a pair of wealthy German businessmen: Udo Geitlinger and Michael Timmer. Geitlinger's son Jens was set up to manage the operation.

I was told that JAC stands for Jens Automobile Company.

Excalibur continued to manufacture their classic limos and roadsters, however it was Jens' love of sports cars that prompted the Cobra endeavor. It is my understanding that an engineer from Classic Roadsters was contacted, and subsequently joined Excalibur who then developed the JAC 427 Cobra. Thus the similarity between the Classic Roadster Cobra and the Excalibur JAC 427 Cobra.
