Change of Strategic Direction

Slack is an example of a company that changed strategic direction as it grew. Starting out as a gaming firm called Tiny Speck in 2009, Slack eventually saw greater opportunity in commercializing the messaging software that it originally had developed strictly for internal use, as an alternative to traditional e-mail, the Journal notes.


By choosing a direct public offering (DPO), Slack should save tens of millions of dollars in fees that otherwise would be paid to investment bankers, underwriters, and members of the selling syndicate in a typical IPO as described below, the Journal notes. Slack has engaged Morgan Stanley to advise market maker Citadel Securities LLC on setting an opening price for its shares, which will depend on buy and sell orders.

Morgan Stanley played a similar role for music streaming service Spotify SA (SPOT), when that company went the DPO route in 2018, the Journal adds. As of the close on June 18, 2019, Spotify's shares were 9.8% below their opening price on their first day of trading, April 3, 2018, and 24.8% below their all-time high, which was reached in intraday trading on July 26, 2018.

How Traditional IPOs Differ

In the vast majority of IPOs, a company that is going public engages an investment banking firm to manage the offering, estimating demand and setting the number of shares to be offered and the offering price accordingly. In any IPO of significant size, the lead investment banking firm will assemble a syndicate that includes other investment banking and broker-dealer firms that will line up buyers, among both retail and institutional investors.

The two main categories of IPOs are best efforts and firm commitment deals. In a firm commitment deal, the investment bankers who underwrite it promise to raise a specific minimum amount for the issuer. By contrast, no such guarantee is made with respect to a best efforts deal. As a result, the fees paid by the issuing company to its underwriters on firm commitment deals are higher, to compensate for the added risk. By choosing a DPO, Slack essentially has opted for a low-cost version of a best efforts offering.
