Pinterest, Inc. co-founder Benjamin Silbermann reported a new insider transaction involving the company’s Class A and Class B common stock on July 21, 2026, according to a Form 4 filed July 22. The filing reports that Silbermann converted shares of Pinterest Class B common stock into Class A common stock and sold Class A shares under a prearranged Rule 10b5-1 trading plan. The disclosed sale included 46,875 shares of Pinterest Class A common stock at a weighted-average price of $22.5371 per share, for estimated gross proceeds of about $1.06 million. The filing states that the sale was executed in multiple transactions at prices ranging from $22.3000 to $22.8300 per share. A separate explanatory note also references sales executed at prices ranging from $22.3300 to $22.8100 per share, likewise reported using a weighted-average price, though the provided filing text does not show the full share count and average price for that additional line item. The shares sold were connected to a conversion of Pinterest Class B common stock into Class A common stock. Pinterest’s Class B shares are convertible at any time at the holder’s option into Class A shares on a one-for-one basis, and they generally also convert automatically into Class A shares upon transfer, subject to certain exceptions. In this case, the conversion was made in connection with the sale of the converted shares. The filing notes that the sales were made pursuant to a Rule 10b5-1 trading plan adopted by Silbermann on February 27, 2026. Such plans allow insiders to schedule future stock sales under predetermined conditions, providing an affirmative defense against claims that trades were made on the basis of material nonpublic information. The filing also references previously reported restricted stock units, noting that those RSUs remain subject to vesting requirements. The supplied filing text does not provide a complete post-transaction ownership total for Silbermann, nor does it list the full transaction table beyond the disclosed 46,875-share sale and related explanatory notes.
