What happened to RBLX
About this case
The complaint alleges that Roblox and its top executives misled investors about how the company's rollout of mandatory facial age verification would affect its growth. According to the complaint, management repeatedly assured investors that Roblox's "tremendous organic growth" would continue, downplayed potential headwinds from the age verification rollout, and on February 5, 2026 issued bookings growth guidance of 22-26% for fiscal 2026 that supposedly reflected confidence in the new age-checking technology. In reality, the complaint alleges, the age verification requirement was significantly hurting user engagement, slowing adoption, reducing on-platform communication, lowering app store ratings, and choking off the organic sign-ups Roblox depended on for growth. The truth emerged on April 30, 2026, when Roblox slashed its fiscal 2026 bookings growth guidance to just 8-12% and disclosed that the age verification rollout had caused much greater damage to engagement and growth than previously suggested, causing the stock to fall approximately 18% in a single day.

Summarizes allegations in the complaint — they are not findings of any court.
We screen hundreds of stock drops every year and file only a handful. If we're investigating this one, it's because we believe in it.
Block & Leviton is run by the partners whose names are on the door — and our clients deal with them directly, whatever the size of the loss. That's the point of staying small.
A dismissed case turned into a $150 million record.* A recovery from a company that went bankrupt. We build cases to go the distance — not to settle cheap.
* Subject to court approval. Prior results do not guarantee a similar outcome.
Who we are — and why we're involved
Block & Leviton represents investors. We never represent the companies we investigate. When a company's own disclosures reveal that shareholders were misled, we investigate and bring claims to recover those losses.
Our clients are people like you: individual investors, retirees, and pension funds harmed when the truth comes out and a stock falls. There is no cost to you to participate, and attorneys' fees are paid only out of a recovery approved by the court.

A record courts have trusted
NextEra Energy — $150 million
The district court dismissed the case. We appealed — and won a unanimous reversal in the Eleventh Circuit Court of Appeals. The result: a $150 million settlement — the largest securities class action settlement in the Southern District of Florida in more than 30 years.*
Dismissed — then revived when we persuaded the court to reconsider its own judgment. Settled in 2026.
Recovered for investors even after Tricida itself went bankrupt.

Common questions
Will this cost me anything?
No. There is no cost to submit your information, no cost to participate, and no out-of-pocket cost ever. If there's a recovery, attorneys' fees are paid from it and must be approved by the court.
Do I have to go to court or sue anyone myself?
No. The case is brought on behalf of all affected investors as a group. Unless you choose to seek a larger role, participating requires essentially nothing from you.
I'm already part of the class automatically — so why submit my information?
It's true: if you bought RBLX during the class period, you're a class member whether or not you contact anyone. Submitting your information lets us evaluate your specific losses, keep you informed as the case develops, and tell you whether you may benefit from a larger role in the case.
The lead plaintiff deadline passed — am I out of luck?
No. That deadline only governed who could seek appointment to lead the case. Your potential claim as a class member is unaffected — if the case succeeds, class members who file valid claims share in the recovery, and we'll keep you informed of every step if you register.
I sold my shares after the drop — am I still eligible?
Possibly, yes. What generally matters is that you purchased shares during the class period and were harmed by the decline. Whether you still hold shares today doesn't necessarily disqualify you — submit your details and we'll evaluate your situation.
Does submitting this form make you my lawyers?
No — and that's a protection for you. Submitting the form only lets us evaluate your potential claim, at no cost. If we determine we can help and you decide to move forward, we'll send you a written retainer agreement that spells out the relationship, the contingency fee, and your rights. You're never committed to anything until you've read and signed it.
What happens after I submit the form?
Our team reviews your submission — usually within one business day. David, our investor liaison, will reach out by phone or email, and our partners are directly involved in every case. You're never obligated to do anything.
