What the Securities Lawsuit Alleges
The case is brought for people who bought Planet Fitness, Inc. stock (NYSE: PLNT) between November 6, 2025 and May 6, 2026. It alleges the company and certain executives made false and misleading statements about “the true state of Planet Fitness' customer acquisition and marketing metrics.” According to the complaint, the updated messaging behind the “We Are All Strong on This Planet” campaign “was failing to resonate with, and was actively intimidating, its core target demographic of fitness beginners and casual gym-goers.”
On May 7, 2026, Planet Fitness said 2026 was “off to a slower than expected start from a net member growth perspective” after “internal and external headwinds during our peak sign-up period,” and that it was “pausing the planned national Black Card price increase pending a broader pricing review.” Per the complaint, it also cut its 2026 revenue growth guidance from about 9% to about 7%, withdrew its three-year growth algorithm and acknowledged its marketing “may have pivoted too far.” The stock fell $19.95, or 31%, from $63.96 to $44.01 in one day. These are allegations; no court has found Planet Fitness liable.
Case Details
Matsunaga v. Planet Fitness, Inc., et al., No. 1:26-cv-00576, filed July 14, 2026 in the U.S. District Court for the District of New Hampshire, assigned to Judge Paul J. Barbadoro. New Hampshire is the company's home state; Planet Fitness is based in Hampton, New Hampshire. The defendants are the company and certain of its officers. It is a federal securities-fraud class action. It does not seek refunds of membership dues or fees.
Status as of September 30, 2026: Early Stage, No Settlement
Planet Fitness's quarterly report filed August 6, 2026 does not single out this case. It says the company is involved in claims and legal actions that arise in the ordinary course of business and does not believe their ultimate resolution “will have a material adverse effect” on its business.

Who the Lawsuit Covers — and Who It Does Not
The proposed class is investors: anyone who bought Planet Fitness common stock between November 6, 2025 and May 6, 2026. Being one of the company's roughly 21.5 million members (its count at March 31, 2026) does not put you in it, and neither does paying a Black Card fee, an annual fee or a buyout fee.
Investors do not have to sign up to stay in the proposed class. The September 14, 2026 date was only the deadline to ask to lead the case; missing it removes no one. If a class is certified or a settlement is reached, a court-approved notice goes to shareholders, usually through their brokers, with its own claim deadline.
For members, the useful question is a different one: were you charged after cancelling the way the contract requires? That is the next section.
Is There Money for Members? No — Here Is What Works Instead
For a member, the money that is realistically recoverable is a charge taken after a proper cancellation. Planet Fitness's own FAQ sets the rules: you can end a membership online through the member portal, in person at your home club, or by written notice mailed to your home club. The club must receive the request at least 8 days before your next billing date, because billing changes can take up to 7 days, and at least 8 days before the annual fee date to stop that fee. A membership with a minimum term that ends early carries a $58 buyout fee. The FAQ adds that some policies “may vary by location based on state and local guidelines.”
If you followed those rules and were still charged, keep your cancellation confirmation, ask the home club in writing for a refund, and if that fails, dispute the charge with your card issuer or bank.

July 14, 2026 — Investors Sue in New Hampshire
Matsunaga v. Planet Fitness, Inc., No. 1:26-cv-00576, is filed in the District of New Hampshire before Judge Paul J. Barbadoro. Weeks of law-firm press releases about the lead-plaintiff deadline follow.

September 14, 2026 — Lead Plaintiff Deadline
The last day for investors to ask to lead the case. It was never a deadline for gym members.

Now — No Settlement
As of September 30, 2026 the case is at the pleading stage. There is no settlement, no fund and no claim form for investors or members.
Three Things to Watch For
A lawsuit with a famous name and no claim form attracts people selling something:
“Claim your Planet Fitness refund” pages
There is no member settlement, so there is no refund portal. A page, email or text asking for your card number, bank login or membership details to “release your share” is collecting data, not filing a claim.
Investor deadlines dressed up as member deadlines
The September 14, 2026 date repeated across many law-firm press releases was a lead-plaintiff deadline for people who bought PLNT stock. It never applied to gym members, and missing it cost no one anything. An ad that suggests otherwise is marketing.
Paid “cancel-for-you” services and look-alike help lines
Sites that charge to cancel a Planet Fitness membership, or list a “cancellation hotline,” are unnecessary. The company's FAQ names its own three routes — the online member portal, your home club in person, or a letter to your home club — and the 8-day timing applies no matter who sends the request.
Planet Fitness Lawsuit — Questions People Actually Ask
Is there a Planet Fitness lawsuit I can join as a member?
Not the one in the news. The 2026 Planet Fitness lawsuit, Matsunaga v. Planet Fitness, Inc., is a securities class action for investors who bought PLNT stock between November 6, 2025 and May 6, 2026. We found no current member class action with a settlement, claim form or deadline. For anything with a live deadline, see our open class action settlements list.
Why did Planet Fitness stock drop, and what does the lawsuit claim?
On May 7, 2026 the company reported slower-than-expected net member growth, paused its planned national Black Card price increase and lowered its outlook; the stock fell 31% that day. The complaint alleges that before then the company made false and misleading statements about its customer acquisition and marketing, while its new campaign was putting off the beginners and casual gym-goers who are its core customers. Planet Fitness has not been found liable.
I bought PLNT stock in that period. What should I do?
Nothing is required to stay in the proposed class; September 14, 2026 was only the deadline to ask to be lead plaintiff. Keep trade confirmations and statements that show your purchase dates and prices. If there is ever a settlement, a court-approved notice and claim form will go out, usually through brokers, with its own deadline. Be wary of anyone charging a fee to “register” you.
How do I cancel Planet Fitness without another charge?
Per Planet Fitness's FAQ, cancel online in the member portal, in person at your home club, or by written notice mailed to your home club. The club must receive it at least 8 days before your next billing date. Your billing dates are in the member portal and on your membership agreement. Save the confirmation, or for a letter, proof of delivery.
Can I avoid the Planet Fitness annual fee?
Only by ending the membership in time. The FAQ says a request to stop the annual fee must reach the club at least 8 days before the annual fee date. Look up that date in the member portal or your agreement before you cancel, not after.
Isn't there a federal “click to cancel” law now?
No. The FTC amended its Negative Option Rule in October 2024, and the U.S. Court of Appeals for the Eighth Circuit vacated those amendments on July 8, 2025. The FTC restarted the process with an advance notice published March 13, 2026 (comments closed April 13, 2026) — a first step, not a rule. Two protections do exist: the federal Restore Online Shoppers' Confidence Act requires online sellers of recurring plans to provide “simple mechanisms” to stop charges, and California has required since July 1, 2018 that a consumer who signed up online be allowed to cancel online; for contracts entered, amended or extended on or after July 1, 2025, the business must also let you cancel at will, without steps that obstruct or delay it. Our subscription settlements guide tracks the rest.
What if Planet Fitness charged me after I cancelled?
Gather your proof: the cancellation confirmation or your letter with its delivery date, your billing dates, and the statement showing the charge. Ask your home club in writing for a refund. If it refuses, dispute the charge with your card issuer or bank, and file a complaint with your state attorney general and with the FTC at ReportFraud.ftc.gov. Complaints help regulators spot patterns; they do not produce a payout on their own.
Were there earlier Planet Fitness lawsuits over fees and cancellation?
Yes. In 2015 a New Jersey member sued in Truglio v. Planet Fitness, Inc., No. 3:15-cv-07959 (D.N.J.), alleging the membership agreement failed to disclose the total payment obligation and used confusing cancellation language. In July 2016 the court let the cancellation-policy claims go forward. We found no claim process from that case that is open today.
Separate from this case: were you injured in the last 2 years?
Class-action payouts are fixed amounts through an administrator. A personal injury claim is a different case — and often worth far more. Free estimate, no obligation.
