The Masimo Securities Fraud Class Action Settlement is a $33.75 million settlement proposed in federal court to compensate investors who purchased Masimo Corporation stock between May 4, 2022, and August 8, 2023, and suffered losses due to allegedly false and misleading statements made by the company. On June 16, 2025, a mediator recommended approval of the settlement, and in early 2026, the court granted preliminary approval, moving the case toward final resolution. This settlement represents a significant recovery opportunity for investors who bought Masimo stock during a period when the company’s executives allegedly misrepresented key business developments.
The case, formally known as Vazquez v. Masimo Corporation, centers on claims that company leadership made false statements about Masimo’s acquisition and integration of Sound United, a consumer audio manufacturer, and about the performance of Masimo’s traditional healthcare business unit. The defendants—Masimo Corporation, Micah Young, Bilial Muhsin, and Eli Kammerman—deny any liability or wrongdoing, but agreed to the settlement to resolve the litigation. For investors who held Masimo stock during the class period, this settlement provides a path to recover a portion of their investment losses.

What False Statements Did Masimo Make to Investors?
The lawsuit alleges that Masimo’s executives made false and misleading statements to investors regarding two critical areas of the company’s business. First, the company allegedly misrepresented its acquisition and integration of Sound United, a manufacturer of consumer audio products that Masimo acquired to diversify beyond its core medical device business. Second, Masimo allegedly made false statements about the performance and prospects of its traditional healthcare unit, which is the company’s original business line and primary source of revenue. These misstatements are alleged to have caused investors to hold or purchase stock at artificially inflated prices.
When companies make false statements to the public markets, they undermine the principle of informed investing. Investors rely on accurate financial disclosures and forward-looking statements to make decisions about buying or selling stock. If a company’s executives knowingly or recklessly make false statements about major acquisitions or core business units, investors may pay too much for stock based on unrealistic growth expectations or misunderstood business fundamentals. In Masimo’s case, the timeline suggests that the truth about these misstatements emerged between August 2023 and the class period’s end, causing stock losses that harmed shareholders who had purchased during the period of alleged deception.
Who Is Eligible to Recover from This Settlement?
The settlement class includes all persons and entities who purchased publicly traded common stock of Masimo Corporation at any point during the class period of May 4, 2022, through August 8, 2023, inclusive. This is a broad definition that captures millions of transactions—from individual retail investors who bought a few shares to large institutional investors and mutual funds that held significant positions. You do not need to be a resident of any particular state to be a class member; the lawsuit was filed in the United States District court for the Southern District of California, but the settlement compensates investors regardless of where they live or how they purchased the stock. One important limitation is that the settlement only covers purchases of Masimo common stock during the specific class period.
If you purchased Masimo stock before May 4, 2022, or after August 8, 2023, you are not eligible for compensation under this settlement. Similarly, if your Masimo holdings came from options, convertible securities, or other derivative instruments, you are not part of the class. Additionally, certain excluded parties—such as Masimo’s officers, directors, and large shareholders—have been carved out of the settlement class. This is a standard provision to prevent insiders from benefiting from settlements designed to compensate ordinary shareholders who suffered losses.
How Much Will the Settlement Pay and When Will I Receive It?
The settlement amount totals $33.75 million, which will be distributed to eligible class members after deducting court-approved attorneys’ fees, administrative costs, and any approved claims administrator expenses. The actual payment you receive will depend on your individual claim amount—calculated based on how many shares you purchased during the class period and the net loss per share suffered. Investors who bought more shares or held them longer will generally receive larger distributions than those who purchased fewer shares or traded more actively. The claims submission deadline is April 28, 2026, which is the last day you can file a claim form to be eligible for payment. Missing this deadline will bar you from receiving any settlement proceeds.
The final settlement hearing is scheduled for May 11, 2026, at 10:00 AM Pacific Time before judge Daniel E. Butcher in the Southern District of California. At this hearing, the court will consider any objections to the settlement and determine whether to grant final approval. Once the court grants final approval and any appeals are resolved, the settlement administrator will begin processing and distributing claims to class members. Distribution typically occurs several months after final approval, though the exact timeline depends on the volume of claims and the complexity of calculating individual claim amounts.
How Do I File a Claim and What Information Do I Need?
To receive payment from the settlement, you must submit a signed claim form by April 28, 2026. You can obtain the claim form and submit it online through the official settlement website at masimosecuritiessettlement.com, or you can request a paper copy if you prefer to file by mail. The claim form will ask for information about your Masimo stock purchases during the class period, including the dates of purchase, the number of shares bought, and the prices paid. You will need to provide documentation of your purchases, which typically comes from your brokerage statements, confirmation emails, or tax documents like your Form 1099-B.
When filling out the claim form, accuracy is critical because the settlement administrator will use the information you provide to verify your claim and calculate your settlement payment. If you cannot locate your original purchase documents, many brokerages will provide account history records if you contact them directly. Some people find it helpful to use their tax returns from 2022 and 2023, as these often contain brokerage statements and capital loss information that can establish your holdings during the class period. If you have questions about the claim process, you can contact the settlement administrator directly using the contact information provided on the settlement website.
What Are the Critical Deadlines and What Happens if I Miss Them?
The absolute final deadline for submitting a claim is April 28, 2026. This date is firm and is not extended. Any claim received after this date will be rejected, and you will forfeit your right to recover from the settlement. This is not a suggestion or a guideline—it is a legal requirement set by the court. Investors who have already lost money due to the alleged fraud should not compound their losses by missing the opportunity to recover through the settlement.
The settlement hearing on May 11, 2026, is when the judge will decide whether to grant final approval to the settlement. Before this hearing, class members have the right to submit written objections to the settlement if they believe it is unfair or that the attorneys’ fees are too high. If you want to object, you must submit your objection in writing to the court and the attorneys involved before the objection deadline specified in the settlement notice. However, most class members do not object to proposed settlements, and objections rarely succeed. After the final approval hearing, there may be additional appeals, but these do not delay claims processing—the settlement administrator typically begins processing approved claims while appeals are pending, though final distributions may be held pending the resolution of any appellate challenges.
What Do the Defendants Say About These Allegations?
Masimo Corporation, along with the individual defendants Micah Young, Bilial Muhsin, and Eli Kammerman, have denied any liability or wrongdoing in connection with the allegedly false statements. This denial is standard in most securities settlements—defendants settle cases not because they admit guilt but because settling is often less expensive and disruptive than continuing to defend the lawsuit through trial. Settlement allows defendants to avoid the uncertainty of a jury verdict, the costs of continued litigation, and the reputational damage of a lengthy public trial. From a practical standpoint, Masimo’s agreement to settle does not mean the company admits fault, and the settlement itself should not be interpreted as proof of misconduct.
The settlement is also neither evidence nor admission of fraud, though it does represent the defendants’ assessment that paying the settlement amount is preferable to the risks and costs of continued litigation. This is an important distinction for investors to understand: settling a lawsuit is a business decision, not a legal determination of guilt. The court has not found that Masimo made false statements or that any defendant engaged in fraud. The court has only preliminarily approved the proposed settlement, meaning it has determined that the settlement is fair and reasonable based on the facts alleged and the strength of the plaintiffs’ claims. Final approval will come only after the May 11, 2026, hearing.
What Happens Next and When Will the Case Be Resolved?
The settlement is now in the preliminary approval phase, and the next major milestone is the final settlement hearing scheduled for May 11, 2026. At this hearing, Judge Daniel E. Butcher will listen to arguments from the plaintiffs’ attorneys, the defendants, any objectors, and potentially the settlement administrator, before deciding whether to grant final approval. If the judge approves the settlement, the defendants will make the $33.75 million payment to the settlement administrator, who will then process claims and distribute payments to eligible class members.
The entire process from final approval to initial distributions typically takes between four and six months, though some complex settlements take longer. After final approval is granted and the settlement fund is distributed, the case will be closed and all claims will be resolved. Investors who receive payment from the settlement will be barred from filing any separate lawsuits against Masimo for the same conduct alleged in the class action, so the settlement provides finality for both the company and the shareholders. For Masimo investors who suffered losses during the class period, the settlement represents their primary opportunity to recover compensation. While no settlement fully compensates investors for their losses, the $33.75 million recovery is substantial and provides meaningful relief for shareholders who purchased stock during the alleged fraud period.
Conclusion
The Masimo Securities Fraud Class Action Settlement is a $33.75 million recovery opportunity for investors who bought Masimo Corporation stock between May 4, 2022, and August 8, 2023. The settlement addresses allegations that company leadership made false statements about Masimo’s acquisition and integration of Sound United and about the performance of the company’s traditional healthcare unit. To receive compensation, eligible investors must file a claim by April 28, 2026, with supporting documentation of their stock purchases during the class period.
If you owned Masimo common stock during the class period, now is the time to gather your brokerage records, verify your purchase dates and quantities, and prepare your claim. The final settlement hearing on May 11, 2026, will bring the case closer to final resolution, after which payments will be distributed to approved claimants. Missing the April 28 deadline will permanently bar you from recovering any settlement proceeds, so treat this deadline with urgency.
