Information Regarding Pacira's 2026 Annual Meeting of Stockholders

Dear Colleagues,

As many of you may be aware, Pacira is currently engaged in a proxy contest in connection with our upcoming 2026 Annual Meeting of Stockholders, in which shareholders will vote on the future direction of the company. Your vote is important to our ability to continue transforming into an innovative biopharmaceutical company.

Our board and executive leadership team are committed to acting in the best interests of the Company and all stockholders, including our employees. We remain confident that Pacira is well positioned to accelerate growth as we continue executing our 5x30 strategy and deliver its intended business results.

Despite this momentum, one of our stockholders, DOMA Perpetual Capital Management LLC ("DOMA"), has chosen to pursue a disruptive proxy contest that we believe is misguided and not in the best interests of Pacira or its stockholders.

Your support and vote are important as we continue building a stronger and more innovative company for the future.

Here's what you can do right now: Vote "FOR" the election of each of the three highly qualified nominees proposed by your board-Chris Christie, Samit Hirawat and Thomas Wiggans-on your universal BLUE proxy card - electronically or by mail. Please DISREGARD any white proxy card or other communication you may receive from DOMA.

Additionally, the board recommends a "FOR" vote for each of our other proposals up for vote: the appointment of KPMG as our independent registered accounting firm; the compensation of our named executive officers; the approval of our amended and restated stock plan; and the approval of our amended and restated employee stock purchase plan ("ESPP").

Most employees will vote electronically through their brokerage account or via instructions received by email. Please refer to the attached voting instructions for step-by-step guidance on how to submit your vote electronically through Fidelity.

If you owned stock as of the close of business on April 22, 2026-including previously-vested awards, ESPP shares, or shares held in brokerage accounts outside of Fidelity-you are entitled to vote those shares.

On behalf of the board, the executive leadership team, and myself, thank you for your continued support and for all that you do every to advance our mission.

Sincerely,

Frank D. Lee

benefits of our share repurchase program; and factors discussed in the "Risk Factors" of Pacira's most recent Annual Report on Form 10-K and in other filings that it periodically makes with the U.S. Securities and Exchange Commission (the "SEC"). In addition, the forward-looking statements included in this document represent Pacira's views as of the date of this document. Important factors could cause actual results to differ materially from those indicated or implied by forward-looking statements, and as such Pacira anticipates that subsequent events and developments will cause its views to change. Except as required by applicable law, Pacira undertakes no intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, and readers should not rely on these forward-looking statements as representing Pacira's views as of any date subsequent to the date of this document.
