between May 3, 2016, and May 6, 2022 , you may be eligible to receive benefits from a

A court has authorized this Notice. This is not a solicitation from a lawyer.
• A $11.5 million settlement has been reached in a class action lawsuit against Nutramax Laboratories, Inc. and
Nutramax Laboratories Veterinary Sciences, Inc. (together, “Defendants”). The lawsuit alleges Defendants
misrepresented the benefits and effectiveness of certain canine supplements branded under the name Cosequin®
both in advertising and packaging. Defendants deny all allegations of fault, wrongdoing, or liability made by the
Plaintiffs. There has been no determination of wrongdoing by the Court.
• You are a Class Member if the following Class definition applies to you: all persons residing in California who
purchased the following canine Cosequin® products for personal use: Cosequin® DS Maximum Strength Chewable
Tablets; Cosequin® DS Maximum Strength Plus MSM Chewable Tablets; Cosequin® Maximum Strength Plus
MSM Chewable Tablets; Cosequin® with MSM Chewable Tablets; Cosequin® DS Maximum Strength Plus MSM
Soft Chews; Cosequin® Maximum Strength Plus MSM Soft Chews; and Cosequin® with MSM Soft Chews
between May 3, 2016 and May 6, 2022. “Products for personal use” means products purchased for household use
by an animal or pet, and not for resale or other business purpose.
• Class Members who submit a timely and valid Claim Form are eligible for a Settlement Payment of up to $25
per unit of Cosequin® Products purchased between May 3, 2016, and May 6, 2022, up to a maximum of $150.
• Each Household is limited to and may only submit one single Claim Form. For purposes of the Settlement,
Household is defined as all persons living at the same physical address.
• The $11.5 million settlement fund shall be used to meet the monetary obligations to Class Members, pay
all settlement payments thereto, service awards, and the Fee and Expense Award ordered by the Court after
submission of the Fee and Expense Application by Class Counsel. If the total amount of Valid Claims is more
than what remains of the Settlement Fund after removing the attorneys’ Fee and Expense Award and service
awards, then the Settlement Payment for each Class Member will be reduced on a pro rata (a legal term meaning
equal) basis.

Basic Information
1. Why is this Notice being provided?
A court authorized this Notice because you have the right to know about the Settlement of this class action lawsuit,
and about all of your rights and options before the Court decides whether to grant final approval of the Settlement.
This Notice explains the lawsuit, the Settlement, your legal rights, what Settlement benefits are available, who is
eligible for them, and how to get them.
The Honorable Fernando M. Olguin of the United States District Court for the Central District of California is
overseeing this class action. The lawsuit is known as Justin Lytle and Christine Musthaler v. Nutramax Laboratories, Inc.
and Nutramax Laboratories Veterinary Sciences, Inc., Case No. 5:19-CV-00835-FMO-SP. The people who filed this
lawsuit are called “Plaintiffs”, and the companies sued, Nutramax Laboratories, Inc. and Nutramax Laboratories
Veterinary Sciences, Inc., are “Defendants”.
2. What is this lawsuit about?
Plaintiffs filed this lawsuit against Defendants on behalf of themselves and all others similarly situated, alleging that
Defendants misrepresented the benefits and effectiveness of certain canine supplements branded under the name
Cosequin® both in advertising and packaging. The lawsuit includes Cosequin®-branded dog supplements purchased
for personal use between May 3, 2016, and May 6, 2022.
Defendants deny the legal claims and deny any wrongdoing or liability. The Court has not made any determination of
any wrongdoing by Defendants or that any law has been violated. Instead, Plaintiffs and Defendants have agreed to a
settlement to avoid the risk, cost, and time of continuing the lawsuit.
3. Why is the lawsuit a class action?
In a class action, one or more people called Class Representatives sue on behalf of other people who have similar
legal claims. Together, the people are a class or class members. One court resolves the issues for all class members,
except for those class members who timely exclude themselves (opt-out) from the class.
4. Why is there a Settlement?
Plaintiffs and Defendants do not agree about the legal claims made in this lawsuit. The lawsuit has not gone to trial,
and the Court has not decided in favor of the Plaintiffs or Defendants. Instead, Plaintiffs and Defendants have agreed
to settle the lawsuit. The Class Representatives and their lawyers believe the Settlement is best for Class Members
because of the Settlement benefits available and the risks and uncertainty associated with continuing the lawsuit.

8. What does the Settlement provide?
As a result of the Settlement, Defendants have agreed to create a Settlement Fund of $11,500,000. Settlement
Payments from the Settlement Fund will be paid to each Class Member who submits a valid and timely Claim Form.
Class Members who submit a timely and valid Claim Form are eligible for a Settlement Payment of up to $25 per unit

The $11.5 million settlement fund shall be used to meet the monetary obligations to Class Members, pay all settlement
payments thereto, service awards, and the Fee and Expense Award ordered by the Court after submission of the Fee
and Expense Application by Class Counsel. If the total amount of Valid Claims is more than what remains of the
Settlement Fund after removing the attorneys’ Fee and Expense Award and service awards, then the Settlement
Payment for each Class Member will be reduced on a pro rata (a legal term meaning equal) basis.
Defendants are also required to remove the following statements on future packaging for the Cosequin® Products:
(1) “Mobility, Cartilage and Joint Health Support”;
(2) “Supports Mobility for a Healthy Lifestyle”; and
(3) “Use Cosequin to help your pet Climb stairs, Rise and Jump!”
9. What am I giving up to receive Settlement benefits or stay in the Class?
Unless you exclude yourself (opt-out), you will remain in the Class. If the Settlement is approved and becomes final,
all the Court’s orders and judgments will apply to you and legally bind you. You will not be able to sue, continue to
sue, or be part of any other lawsuit against Defendants and the Released Parties about the legal claims in this lawsuit
that are released by the Settlement Agreement. The rights you are giving up are called “Released Claims.”
10. What are the Released Claims?
Section 9 of the Settlement Agreement describes the Releases, Released Claims, and Released Parties, in
necessary legal terminology, so please read this section carefully. The Settlement Agreement is available at

cannot object to the Settlement.
The Fairness Hearing
21. When and where will the Court decide whether to approve the Settlement?
The Court will hold a Fairness Hearing on AUGUST 13, 2026, at 10:00 a.m. before the Honorable Fernando M.

this hearing, the Court will consider whether the Settlement is fair, reasonable, and adequate, and decide whether to
approve the Settlement, Class Counsel’s attorneys’ Fee and Expense Award, and service awards.
If there are objections that were filed by the deadline, the Court will consider them. If you file a timely, written
objection, and you would like to speak at the hearing, you must indicate in your written objection that you wish to
speak at the Fairness Hearing.
Note: The date and time of the Fairness Hearing are subject to change without further notice to the Class. The Court
may also decide to hold the hearing via video conference or by telephone. You should check the Settlement Website
www.CosequinCASettlement.com to confirm the date and time of the Fairness Hearing have not changed.
22. Do I have to attend the Fairness Hearing?
No. Class Counsel will answer any questions the Court may have. However, you are welcome to attend at your own
expense. If you file an objection, you do not have to attend the Fairness Hearing to speak about it. As long as you file
your written objection by the deadline, the Court will consider it.

speak for yourself at the Fairness Hearing. This is called making an appearance. You can also have your own lawyer
speak for you, but you will have to pay for the lawyer yourself.
If you want to appear, or if you want your own lawyer instead of Class Counsel to speak for you at the hearing,
you must follow all of the procedures for objecting and file a Notice of Intention to Appear as listed above—and
specifically include a statement whether you or your lawyer will appear at the Fairness Hearing.

24. What happens if I do nothing at all?
