What this transaction means for investors

Shares of Shift4 Payments, or Shift4, as the company refers to itself, were soaring on March 24, up some 16% to $51.25 per share. It was likely due to some good news for the stock over the past few weeks, punctuated perhaps by this insider buy. Isaacman founded Shift4, but left the company in December to become the administrator of NASA in the Trump Administration.

Shift4 stock had been trading at a 52-week low of around $40 per share just last week. Its forward P/E ratio plummeted to 7, and its five-year PEG ratio is a minuscule 0.28, suggesting a good value. This low valuation may be another catalyst for the stock price to bounce as it has.

A major catalyst is the acquisition of Bambora North America, which brings its platform of more than 140,000 merchants to Shift4. The merchants will have access to Shift4’s payments and commerce solutions. Further, the acquisition will create opportunities for cross-selling as the Bambora platform is integrated with more than 500 independent software vendors.

The company also announced on its Q4 earnings call that it had formed a partnership with XAI, Elon Musk’s company, to incorporate AI into its business.

Analysts are generally bullish on Shift4 stock, with a median price target of $60 per share, which suggests 17% upside.
