(Reuters) - Shares of McAfee Corp MCFE.O fell 7% in their market debut on Thursday, marking a disappointing opening for the cyber security firm after it raised about $620 million in its initial public offering. The stock opened at $18.60 per share, compared with its IPO price of $20 per share. At the debut price, the company was valued around $8 billion. McAfee priced its IPO towards the lower end of its targeted range between $19 and $22 per share. The offering marks a return to public markets for McAfee, which was bought by Intel Corp INTC.O in 2011. It was then turned into a joint venture with TPG Capital in a deal which valued the company at $4.2 billion, including debt. Thoma Bravo took a minority stake in McAfee in 2017. In the first half of 2020, McAfee’s net revenue was $1.4 billion with a net income of $31 million. “The markets we play in are large, growing and important and we realize there’s a great need for what we bring to the table,” McAfee Chief Executive Officer Peter Leav told Reuters. “We are going to invest in our fast-growing consumer business and in our enterprise businesses, where there’s a need for a broader portfolio.” The cyber security firm"s IPO comes in the wake of strong market debuts from gaming platform Unity Software Inc U.N and online prescription drug firm GoodRx GDRX.O.
