CDMO Transaction Employee Letter

Team,

I'm reaching out with an important update about our Company. Avid Bioservices has entered into a definitive agreement to be acquired by GHO Capital Partners and Ampersand Capital Partners for $12.50 per share in cash in a transaction valued at $1.1 billion. Upon completion of the transaction, Avid common stock will no longer be publicly traded.

Avid was founded over 30 years ago as a company devoted to developing and manufacturing biologics. Since then, we have grown and evolved into a leading CDMO that provides commercial biologics and other services to large pharmaceutical and biotech customers supporting patients around the world.

After years of investment and expansion, we believe that now is the right time to move forward as a private company with new owners that will support our next phase of growth.

For those of you who are unfamiliar, GHO and Ampersand are experienced healthcare industry investors based in London and Boston, respectively. With a transatlantic focus, GHO brings a collaborative approach to partnering with great companies like ours. GHO's mission is to support innovation to deliver better, faster and more accessible healthcare to make a difference to patients, healthcare systems and society. GHO has a deep understanding of the CDMO sector and an impressive track record in helping businesses in our sector drive value. Ampersand is a healthcare and pharma-focused private equity firm with more than 30 years of experience dedicated to the life sciences sector.

GHO and Ampersand are acquiring Avid because they believe in our potential. With their combined sector specialism, strong track record of unlocking value and significant industry experience, we will be able to build on and extend Avid's commitment to producing the biologics that contribute to creating life-saving therapies.

Our ability to take this step from a position of strength is a testament to the Company's strong foundation and the dedication of our employees. I'm incredibly grateful for your contributions that have gotten us to this point, and I know that our employees will continue to drive our success going forward. I hope you share my excitement about the possibilities ahead.

Next Steps: Business as Usual

While we are announcing this transaction today, it is subject to customary closing conditions and the receipt of transaction-related regulatory approvals and is expected to close in the first quarter of 2025. Between now and then, it is business as usual at Avid. The best way that you can help is by staying focused on your day-to-day responsibilities and meeting and exceeding the needs of our customers by providing them the service, high-quality products and reliability they expect from us.

We will keep you informed as we move forward, starting with a virtual town hall meeting today at 6:00 pm ET / 3:00 pm PT to discuss this announcement. An invitation will be distributed separately.
