If given a similar multiple to Barracuda, which was bought for 20 times current year cash flow, Symantec would be worth $30 to $35 per share in a buyout, Barclays analyst Saket Kalia tells investors in a research note. The analyst points out that Thoma Bravo, which Reuters reported today has approached Symantec to express interest in a potential takeover, acquired Blue Coat in 2012, taking it private until 2015 when it sold the business to Symantec. As such, the private equity firm has been active in security, Kalia adds. He has an Equity Weight rating on Symantec. The stock in midday trading is p 14%, or $2.80, to $22.82.
