The following is an email message delivered to Trubion’s employees by Emergent’s Chairman and CEO, Faud El-Hibri.
Dear Trubion Employees,
I would like to personally express to you how excited I am at the prospect of combining our two companies. I also know that many of you may be curious about our motivation for this transaction and whether or not you will have a job. Let me address both of these for you.
First, what is our motivation for this transaction. In a nutshell, it is all about Emergent's growth. We have for some time been focused on diversifying our product portfolio and making deeper inroads into the commercial marketplace where we believe we have the greatest opportunity to increase shareholder value. Your company -with its robust pipeline of promising products, its proprietary and innovative platforms, its therapeutic focus to serve unmet medical needs in oncology and autoimmunity, and most importantly its people - neatly fit our criteria for an attractive acquisition.
Second, and as important, what is in store for you. To put it simply - you are the reason for Trubion's success. I have heard much about the world-class work being done at Trubion and the dedicated and enthusiastic employees that are accomplishing it. You have the expertise, skills and knowledge to not only continue the development of the existing programs, but to also apply your knowledge and skills in developing new and exciting programs for the future. Retaining not only the Seattle facility as a therapeutics-focused product development site, but also as many employees as possible, is very important to me.
At the end of the day, companies are really about people; their commitment, passion and dedication to contribute in a significant way. That is why I would like the integration of our two companies to be collaborative and progress as seamlessly as possible. Jim Jackson, Ph.D., Emergent's Chief Scientific Officer, will serve as Integration Leader. Jim was the primary scientific lead in the due diligence process and has been a steady and enthusiastic champion for this acquisition. He also comes with the experience of having worked at a company acquired by Emergent. This Thursday, Jim, along with Don Elsey, Emergent Chief Financial Officer, Jacob Licht, Director Corporate Development and Integration Manager, and Bob Burrows, Vice President Investor Relations, will be in Seattle to meet with all employees and elaborate more on Emergent, our strategy, the integration process, and to take your questions. I encourage you to please attend and be as open and as candid as possible with them.
In closing, I would like to re-iterate that I believe this is a very exciting time. We have an opportunity here to do great science, significantly improve patients' lives, grow as individuals, and to jointly build a greater company. Together, I see great opportunities ahead. We are well-positioned to emerge as a leading biopharmaceutical company specialized in vaccines and biotherapeutics. I hope in the near future to visit Trubion and I look forward to personally welcoming you to Emergent once the transaction has closed.
Sincerely yours,
Fuad El-Hibri
Emergent BioSolutions Chairman and CEO
