What this transaction means for investors
The July 15 and July 17 sale of Cloudflare stock by CFO Thomas Seifert does not appear to be a cause for investor concern, since these were non-discretionary transactions. The July 15 sale was for tax withholding purposes in connection with the vesting of RSUs. The July 17 disposition was part of a pre-established Rule 10b5-1 plan.
Such plans allow insiders to sell shares at predetermined times to avoid concerns of trading on non-public information. Also, Seifert’s post-sale equity stake in Cloudflare is substantial, considering his more than 200,000 shares held directly and indirectly through an annuity trust, and over 300,000 derivative securities in various other trusts. This ensures his continued alignment with shareholder interests.
Cloudflare stock has gone on an incredible run, reaching a 52-week high of $291 on July 15, and for good reason. The company posted a strong 34% year-over-year increase in revenue to $639.8 million in the first quarter. Its business is poised for continued growth due to the rise in bots produced by artificial intelligence. The bots comprise 57% of all internet activity, eclipsing humans for the first time. Consequently, Cloudflare’s services are more in demand than ever to halt these bots.
