Exhibit 99.1

Leadership resource: FAQs

DEAL:

What are the details of this transaction?

We have entered into an agreement to be acquired. Under the agreement, Viatris has agreed to acquire all of the outstanding shares of common stock of Pacira for $36.50 per share in cash, representing an aggregate equity value of $1.65 billion.

Why is Viatris acquiring Pacira?

Everything that has been built since Pacira was founded 20 years ago—and the progress we have made in recent years, from our evolution into an innovative biopharmaceutical company and execution of our 5x30 strategy to the strength of our portfolio and pipeline led by PCRX-201—has made Pacira a company others want to be part of.

Viatris is attracted not only to the strength of our science and the impact we have made for patients and providers, but also to the differentiated capabilities we bring: a proven commercial organization with deep customer relationships and expertise in launching and growing non-opioid pain therapies; specialized manufacturing capabilities and operational know-how; a strong development and regulatory foundation; and an experienced team with a track record of execution.

Pacira will become a core part of Viatris's innovative medicines portfolio. The combination of their investigational non-opioid and our assets, position Viatris as a leader in non-opioid pain management therapies, an area where we know patients and healthcare providers continue to seek more treatment options.

This agreement reinforces the value of all that we have built and, most importantly, reflects the immense talent and contributions of all of you.

When will the transaction with Viatris close?

We expect the transaction to close by the end of 2026, subject to customary deal closing conditions.

What is the plan for our product and pipeline?

Pacira will become a core part of Viatris's innovative medicines portfolio. They have the ability to take EXPAREL and ZILRETTA further, and to potentially advance our pipeline faster than we could on our own.

What should I focus on during this time before the transaction is closed?

It is important that we remain focused and continue delivering strong results in Q4. Employees should stay focused on their goals and priorities. If you have questions about whether your day-to-day responsibilities or priorities may be affected, please speak with your manager.

How can we interact with Viatris during this time period?

Until the transaction closes, Pacira and Viatris remain separate, independent publicly traded companies and must continue to operate that way. This separation is important to comply with federal antitrust and securities laws, preserve independent decision-making, avoid inappropriate sharing of competitively sensitive or confidential information, and ensure that neither company assumes control of the other before all required approvals are obtained and the transaction is closed. Employees should continue to conduct business as they normally would and interact with Viatris only through approved channels and established transition-planning processes.

How should I communicate with my customers about the acquisition?

We will be sending letters to our customers, distributors, partners, KOLs, societies and patient advocacy groups in the coming days. If you receive any questions from your customers, please reinforce that nothing has changed in terms of day-to-day business, and that you are still their dedicated Pacira representative and will support them as usual.

EMPLOYEE MATTERS:

What will happen to Pacira employees?

Viatris is acquiring Pacira as a whole organization. Viatris will evaluate the Pacira business, organizational structure and talent needs of the combined organization and will make strategic determinations about how best to integrate Pacira’s programs and people into their business after closing. Although the details have not yet been finalized, Pacira and Viatris leadership recognize how important this information is to employees and will share updates as soon as they become available.

Between signing and closing of the transaction, Viatris and Pacira will remain separate, independent companies. Our focus remains on serving our customers and achieving our Q4 goals. Currently, we don’t anticipate any changes to the organizational structure prior to closing. Your manager remains your primary resource for questions about your current role, responsibilities, and priorities.

How and when will I know if I have a role with Viatris?

We understand that change of this magnitude provokes a high degree of uncertainty. Pacira and Viatris leadership recognize how important this information is to Pacira employees and will share updates as soon as decisions are made and we’re able to share them. In the meantime, we encourage Pacira employees to remain focused on their current goals and Q4 deliverables. If you have questions about your day-to-day responsibilities or priorities, please speak with your manager.

If I am offered a position with Viatris can I decline it?

Yes. Employees who choose not to continue with Viatris would be considered to have voluntarily resigned and would not be eligible for separation benefits.

What will happen to my equity awards?

We are pleased to share that upon the closing of the transaction, outstanding equity awards (whether vested or unvested) will be converted into a right to receive an amount of vested cash, which will be calculated pursuant to the terms of the agreement. Payments of such amounts will be made as soon as reasonably practicable after closing and will be subject to applicable tax withholdings. Additional details will be communicated on a future date.

What will happen to my restricted cash awards?

We are pleased to share that upon the closing of the transaction, outstanding restricted cash awards (whether vested or unvested) will be converted into a right to receive an amount of vested cash, which will be calculated pursuant to the terms of the agreement. Payments of such amounts will be made as soon as reasonably practicable after closing and will be subject to applicable tax withholdings. Additional details will be communicated on a future date.

What happens if I am currently enrolled in the 2014 Employee Stock Purchase Plan?

Our 2014 Employee Stock Purchase Plan (“ESPP”) will terminate upon the closing of the transaction, and your accumulated contributions for the current offering period will be used to purchase ESPP shares prior to closing on a date determined by the Pacira Board of Directors. At closing, the purchased ESPP shares will be converted into the right to receive an amount of cash per share determined pursuant to the agreement, and any cash balance in your ESPP account will be refunded to you. Payments made in connection with the transaction will be subject to applicable tax withholdings. Additional details will be communicated as they are finalized.

Will I receive a 2026 annual corporate bonus?

Following signing of the agreement, Pacira employees participating in the 2026 annual corporate bonus program remain eligible to earn a 2026 annual bonus, based on actual performance, under the terms and conditions of that program. Accordingly, Pacira employees should remain focused on their goals and Q4 deliverables. If any changes are made to the terms of the program before the transaction closes, we will communicate those changes to participants.

Will I receive my Q4 2026 sales incentive payment?

Following signing of the agreement, Pacira employees participating in a sales incentive plan remain eligible to earn incentives under the terms and conditions of their plan. Accordingly, Pacira employees should remain focused on their goals and Q4 deliverables. If any changes are made to the terms of a sales incentive plan before the transaction closes, we will communicate those changes to participants.

What happens to my benefits?

Until the transaction closes, Pacira continues to operate as an independent company, and our benefits programs will remain in place. Viatris may choose to make changes after closing and, if it does so, will communicate those changes to employees.

We saw notifications from HR about open enrollment. Do I still need to enroll in benefits for 2027?

Yes. Pacira employees should make their 2027 benefit elections during Open Enrollment between October 14^th and 30^th as scheduled. Until the transaction closes, Pacira continues to operate as an independent company, and our benefits programs will remain in place. We are proceeding with planned activities and benefit administration processes, including Open Enrollment, unless and until we receive information that requires a different approach. If any changes are needed before the transaction closes, we will communicate them to Pacira employees.

Do our current approval processes for hiring, contracts, spend, etc. change during the period between now and when the transaction closes?

While we are still operating as a separate company until the transaction closes, Pacira has agreed to standard interim operating covenants with Viatris, which require approval or consent on certain matters of significance intended to preserve the value of Pacira prior to closing.

Will my manager change?

Until the transaction closes, Pacira is operating as a separate company. Pacira will continue to manage its business, and our focus remains on serving our customers and meeting our goals. If there are changes that affect our teams, we will communicate them through the normal course of business.
