Slack files to go public without underwriters

Slack Technologies Inc has filed to go public on the New York Stock Exchange, according to a regulatory filing dated April 26. Slack did not list how many shares it would sell or their price range. The filing also did not list underwriters. Slack is going public through a direct listing and will publicly offer shares of the company to anyone who wants to buy them on opening day, recode said. Slack said in the filing that listing its stock on the NYSE without underwriters “is a novel method for commencing public trading in shares of our Class A common stock, and consequently, the trading volume and price of shares of our Class A common stock may be more volatile than if shares of our Class A common stock were initially listed in connection with an underwritten initial public offering.”  Slack is backed by Accel, Andreessen Horowitz, Social Capital and SoftBank.
