This acquisition provides a unique opportunity to greatly enhance our aviation capabilities and establish ABM as the industry leader in this vertical, as well as provide solid long term growth opportunities. By combining ABM and Air Serv, we will create an aviation vertical with over $650 million in annual revenue and will be in an outstanding position to meet the end-to-end needs of the airlines and airport authorities. In addition, the U.K. operations will enable us to further grow the aviation vertical internationally and will serve as a strategic base as we seek to expand our global presence in other verticals. Upon closing, the current leadership team at Air Serv will serve as the foundational framework for the aviation vertical. We are very pleased to have Air Serv join ABM and take the lead in providing integrated facility solutions for our aviation clients."
