This Release Contains Inside Information.

SLOUGH, England and RICHMOND, Va., Dec. 7, 2022 /PRNewswire/ -- Indivior PLC (LON: INDV) will hold a Capital Markets Day today in New York City. The event will be hosted by Mark Crossley, Chief Executive Officer, along with members of the Indivior executive leadership team and will detail the Company's strategic growth plans and roadmap for delivering long-term shareholder value.

"We have made tremendous progress executing on our strategic priorities," said Mark Crossley. "We are the pioneer and global leader in addiction treatment and science and are well-positioned to transform the lives of the increasing number of patients affected by the opioid crisis, one of the most urgent public health emergencies of our time. Today, my team and I are excited to provide a deep review of our business and to highlight the compelling opportunities we have to innovate in the treatment of addiction and serious mental illness while delivering profitable growth and significant value creation for shareholders."

• Increases SUBLOCADE peak annual net revenue (NR) expectations to >$1.5 billion

Indivior expects SUBLOCADE® (buprenorphine extended-release) injection to achieve a NR run rate of $1 billion by the end of 2025, driven by its focus on further developing the Organized Health Systems (OHS) channel and pursuing the large opportunity in the U.S. Justice System. Longer term, based on the expected positive market dynamics for buprenorphine medication-assisted treatment (BMAT) and on continued execution against its OHS strategy, Indivior now expects to deliver SUBLOCADE peak potential NR of >$1.5 billion.

• Expects to achieve attractive double-digit % NR compounded annual growth rate (CAGR) over the medium-term

Indivior expects to achieve a double-digit percentage NR CAGR over the medium-term, driven primarily by SUBLOCADE in the United States and growing NR contribution from PERSERIS® (risperidone for extended-release injection). Within this outlook, which is based on its current business portfolio, Indivior also expects a return to NR growth in the Rest of the World driven by new products SUBLOCADE (SUBUTEX® PR) and SUBOXONE® (buprenorphine/naloxone) Film. Additionally, the Company assumes the U.S. market share of SUBOXONE Film, which it does not promote, will trend towards historical analogs for genericized medicines.

• Operating margin expansion opportunity from scalable business model

Indivior expects to achieve significant operating margin expansion over the medium-term driven by an improving gross margin and focused management of operating expenses. Following the significant structural growth investments behind SUBLOCADE and PERSERIS in the past two years, selling, general and administrative (SG&A) expenses are expected to grow at a more moderate pace and to decline as a percentage of NR. This impact is expected to be partly offset by an increase in R&D expenses as a percentage of NR towards industry benchmarks as the Company seeks to build a strong and balanced pipeline focused on addiction treatments.

• Disciplined capital allocation approach focused on driving growth and potential returns of excess cash

In the past two years, Indivior's healthy balance sheet and improved cash flow have supported a balanced approach towards capital allocation, focused on investment in key growth priorities, diversifying the business, delivering shareholder returns and meeting other stakeholder obligations. The recently announced definitive agreement to acquire Opiant Pharmaceuticals, Inc. (NASDAQ: OPNT) is indicative of Indivior's commitment to diversify its product portfolio and to expand its global leadership in addiction treatment and science.

• Listing on NASDAQ targeted for the Spring of 2023

At its Extraordinary General Meeting (EGM) in September of this year, Indivior received strong support from its shareholders for an additional share listing in the United States. Having carefully evaluated the available options, Indivior has chosen NASDAQ as its U.S. trading venue. The additional listing is expected to elevate Indivior's profile in the Company's largest market and to attract a broader group of biopharma-focused investors and analysts.

The Group reiterates its FY 2022 guidance published on October 27, 2022.
