Keith Alexander, has agreed to be taken public through a merger with blank check company LGL Systems Acquisition Corp. McLean, Virginia-based IronNet will list on the New York Stock Exchange and trade under the ticker symbol “IRNT” upon the deal’s completion, which is anticipated in the third quarter. The new company expects to receive approximately $267 million in net proceeds from the transaction and is seeking a $1.2 billion overall valuation, IronNet said Monday.
