Roblox Shares Fall Most in Four Years on Slowing User Growth

Roblox Corp. shares plunged the most in more than four years on Friday after the video game company reported fewer daily users in the first quarter than analysts expected, due to safety features it implemented to restrict how kids can use the platform.

The video-game company, which is popular with younger players, also lowered its forecast for full-year bookings, a measure of sales, attributing the change to Roblox’s “aggressive push to enhance safety.”
