Slinger Bag, a manufacturer of tennis ball launchers that began in Israel, has gone public in the U.S. through the reverse acquisition process. The company acquired the publicly traded Lazex Inc., changed the name to Slinger Bag and adopted the ticker symbol of “SLBG.”

The name change and ticker symbol were reviewed and processed by the Financial Industry Regulatory Authority (FINRA) and have been effective as of the opening of trading on November 21.

Czech-based Lazex in September was acquired by the formerly privately held Slinger Bag Americas Inc., a Delaware corporation whose CEO is Mike Ballardie, formerly CEO of Prince.

Slinger Bag was one of five finalists in the Start-Up Challenge sponsored by the Sports & Fitness Industry Association (SFIA).
