Significantly Enhances Cosette's Ability to Drive Further Growth Through Investments in R&D and Business Development

Bridgewater, NJ, Conshohocken, PA, and New York, NY - Avista Capital Partners ("Avista"), a leading New York-based private equity firm focused exclusively on healthcare, and Hamilton Lane, a leading global private markets investment management firm (Nasdaq: HLNE), today announced that funds managed by Hamilton Lane have acquired a significant equity interest in Cosette Pharmaceuticals ("Cosette"), a US-based specialty pharmaceutical company, from Avista and its co-investors.

Since Avista's initial investment in Cosette in December 2018, and under the leadership of a new executive management team, Cosette has successfully launched new and innovative products across its portfolio through a significant R&D effort as well as acquisitions and licensing deals which have expanded the company's presence across existing and new markets. This includes the recent acquisition of Ambien® and Ambien CR® in the United States from Sanofi US. These initiatives have led to robust historic EBITDA growth and free cash flow generation while positioning Cosette to capitalize on compelling opportunities ahead.

Apurva Saraf, President and CEO of Cosette, stated, "This partnership is a testament to the remarkable transformation our business has achieved over the past four years, driven by an unwavering commitment to strategic business development and operational excellence. I am immensely proud of the entire Cosette team for their dedication in delivering this robust growth. We have successfully diversified our portfolio with branded products such as Clomid®, Ambien®, and Benicar®, along with innovative, patent-protected drugs like Vyleesi® and Intrarosa®. With our strong R&D and business development pipeline, we are well positioned to drive substantial growth in partnership with Avista and Hamilton Lane."

David Burgstahler, Managing Partner and CEO of Avista, added, "We value Avista's long-term relationship with Hamilton Lane and look forward to collaborating with them as a strategic partner to drive growth and value at Cosette. Our collective expertise will prove invaluable as Cosette evaluates larger M&A opportunities as part of the company's growth strategy."

Ken Binick,Managing Director and Co-Head of Direct Equity Investments at Hamilton Lane, said, "We are excited to advance our partnership with Avista and the Cosette management team. This is a compelling opportunity for us to invest in what we believe to be a high-quality asset and management team with a demonstrated track record of impressive growth and a clear path to further value creation."

This transaction enhances Cosette's balance sheet to continue to drive growth through investments in R&D and strategic acquisitions. The transaction will catalyze Cosette's ongoing mission to build a durable, high growth, branded pharmaceutical company in the near term.

In conjunction with the transaction, Cosette also entered into a new term loan financing with Hayfin Capital Management, and a new revolver provided by UBS Investment Bank, Capital One, National Association and Santander Corporate & Investment Bank, who acted as joint lead arrangers and joint bookrunners for the financing.
