SANTA MONICA, Calif., Nov. 14, 2022 (GLOBE NEWSWIRE) -- Opiant Pharmaceuticals Inc. (NASDAQ:OPNT) today announced that it has entered into a definitive merger agreement to be acquired by Indivior Inc, a subsidiary of Indivior PLC (LON: INDV). Under the terms of the agreement, Indivior will acquire all of the outstanding shares of Opiant for upfront consideration of $20.00 per share in cash at closing, plus contingent value rights (CVRs) representing, if achieved, potential additional payments over a period of seven years of up to $8.00 per share. Achievement of the CVR payments, if any, are based on attaining certain revenue thresholds for OPNT003, nasal nalmefene, Opiant's investigational treatment for opioid overdose, as detailed below.

The upfront payment at closing of $20.00 per share represents a premium of approximately 111% to Opiant's closing share price on November 11, 2022, and 99% premium to the 30-day volume-weighted average share price. Inclusive of each of the CVR payments, the total potential transaction value represents a premium of up to 195% and 178%, respectively. The transaction has been unanimously approved by the Boards of Directors of each company.

"We are pleased to have reached an agreement that reflects the great potential Opiant has created with OPNT003 and our pipeline of medicines," said Roger Crystal, M.D., Opiant President and Chief Executive Officer. "This transaction provides Opiant shareholders with immediate value in addition to the potential future upside from the CVRs. This transaction will also enable us to leverage Indivior's commercial strength and resources to maximize the value of OPNT003 and our pipeline assets. Importantly, I want to thank our talented team, who have worked tirelessly to progress our Company to this point and look forward to the achievements still to come."

"Our work has never been more critical, with reported overdose deaths in the United States occurring at near record numbers," said Mark Crossley, Chief Executive Officer of Indivior. "Opiant's portfolio of product candidates is an excellent strategic fit that diversifies and strengthens our offerings, while Indivior's strong commercial capabilities will propel a combined product pipeline with the potential to help patients along a continuum from addiction and rescue to recovery. We look forward to working with Opiant's talented team as we undertake our shared mission of helping people with substance use disorders."

Transaction Details

Under the terms of the merger agreement, Indivior will acquire all outstanding shares of Opiant for upfront consideration of $20.00 per share in cash, plus up to $8.00 per share in CVRs that may become payable if certain net revenue milestones are achieved by Opiant's lead asset OPNT003 over the applicable seven-year period.

Pursuant to the CVRs, Indivior will pay $2.00 per CVR if OPNT003 achieves the following net revenue thresholds during any period of four consecutive quarters prior to the seventh anniversary of the U.S. commercial launch: (i) $225 million, (ii) $300 million, and (iii) $325 million. The remaining $2.00 per CVR will become payable if OPNT003 achieves net revenue of $250 million during any period of four consecutive quarters prior to the third anniversary of the U.S. commercial launch. There can be no guarantee that the CVR payments will be achieved as the future performance of OPNT003 is subject to several risks and uncertainties.

The transaction is subject to customary closing conditions, including U.S. antitrust clearance, clearance by the Committee on Foreign Investment in the United States (CFIUS) and receipt of approval of Opiant's shareholders. The members of the Board of Directors of Opiant, who hold approximately 4.5% of the outstanding Opiant shares, have entered into a voting agreement with Indivior and agreed to vote their shares in favor of the transaction. Pending approvals, the parties anticipate completing the transaction in the first quarter of 2023.

Earnings conference call

Given the proposed transaction, Opiant will not be hosting the previously scheduled earnings conference call on Monday, November 14, 2022.

About OPNT003, nasal nalmefene

OPNT003, nasal nalmefene, is a high-affinity mu-opioid receptor antagonist that reduces the binding of opioids to this receptor, limiting respiratory depression, the primary cause of overdose injury and death. In a head-to-head pharmacodynamic study, OPNT003 produced a reversal of remifentanil-induced respiratory depression that was nearly twice that produced by nasal naloxone 4mg at the primary endpoint of five minutes. The intrinsic properties of nalmefene, taken together with results from Opiant's pharmacokinetic and pharmacodynamic studies, are consistent with the potential of OPNT003 to provide a fast and sustained reversal of opioid overdose. Opiant has initiated a rolling submission of a New Drug Application to the FDA for OPNT003, using the 505(b)(2) pathway and intends to complete the filing in the fourth quarter of 2022. OPNT003 was granted Fast Track Designation in November 2021.
