GHO and Ampersand’s deep experience in CDMO investing to support Avid’s next stage of rapid growth including expanded offerings, talent investment and greater geographic reach

London, UK, Boston, MA and Tustin, CA, February 5, 2025 — GHO Capital Partners LLP ("GHO"), the European specialist investor in global healthcare, and Ampersand Capital Partners (“Ampersand”), a private equity firm specialising in growth equity investments in the life sciences and healthcare sectors, today announced the successful closing of the previously announced acquisition of Avid Bioservices (“Avid” or the “Company”), a dedicated biologics Contract Development and Manufacturing Organisation (“CDMO”) working to improve patient lives by providing high quality development and manufacturing services to biotechnology and pharmaceutical companies.

Avid has experienced significant growth in recent years, offering its clients full lifecycle capabilities—from concept to commercial supply. With substantial investment already made by the Company in its capacity at its state-of-the art facilities and its expertise in bioprocess optimisation, analytical testing, and regulatory compliance, Avid delivers high-quality, industry leading complex biologics to a roster of international customers.

GHO has considerable expertise in the CDMO sector through investments in its portfolio in companies like Ardena, Sterling Pharma Solutions, RoslinCT, and Alcami Corporation. Its strategy focuses on expanding technological capabilities, driving acquisitions, and supporting transatlantic expansion across the CDMO value chain, from early-stage development to commercial manufacturing. Leveraging its healthcare expertise and network, GHO transforms CDMOs to enhance their services and market reach, ultimately delivering better, faster and more accessible healthcare.

Alan MacKay and Mike Mortimer, Managing Partners of GHO, commented: “We are delighted to start 2025 with the completion of this transaction, our first public to private deal. GHO has a deep understanding of the CDMO sector and Avid perfectly exemplifies a company that is operating in high growth markets supporting the growing biotech sector in research and development and big pharma and large biotech for the commercialisation of cutting-edge biologics. Avid's recent investments, both in capacity and its exemplary team, have created a strong foundation for future growth. We look forward to partnering closely with the Avid team to unlock the business’s full potential.”

Nick Green, President and CEO of Avid, said: “Avid has succeeded by evolving and adapting to meet our customers' complex development and manufacturing needs. The completion of this transaction marks an exciting milestone as we move forward with new owners in GHO Capital and Ampersand who will provide us with access to resources that will accelerate our growth. With their support, we are well-positioned to enhance our capabilities, expand our service offerings, and deliver even greater value to our customers in this next phase of our journey."

David Anderson, General Partner of Ampersand, added: “Avid has earned its reputation as a leader in biopharmaceutical development and manufacturing through technical excellence, customised solutions, and consistent regulatory compliance. By combining our deep industry expertise with Avid's established capabilities, we are positioned to deliver enhanced value and accelerate innovation for clients globally.”

On 7 November 2024, GHO and Ampersand entered into a definitive merger agreement for Avid to be acquired by funds managed by GHO and Ampersand in an all-cash transaction valued at approximately $1.1 billion. With the completion of the transaction, Avid’s stockholders are entitled to receive $12.50 per share in cash. The Company's common stock has ceased trading and will be delisted from Nasdaq.
