Thank you, Tracy. Still, it's important to spend some time on today's call sharing a few highlights from our updated strategic plan. We've reached a very critical stage in our company's evolution by continuously developing and improving our business, primarily towards additional service lines and focused growth strategy. This strategy has served the company very well for many, many years and has brought us to places we could only have imagined years ago. Our service lines have now reached critical mass throughout the U.S. We've been working diligently to create a new brand, which I'm very proud of, and have also focused on breaking down historical organizational walls to create oneABM. Every day, I hear success stories where key managers have reached across the aisles, if a colleague from another business unit become successful, and nothing makes me happier than just seeing this collaboration take place throughout the organization.
Our vision is to become a company where collaboration is part of our DNA, and our domain expertise and vertical market growth are generated through a strategic focus on geographical markets like never before.
We're updating our strategy. We've been analyzing our marketplace, our competitors and our strategic strength. What we determined is that while it's important to take advantage of our strength and position ourselves as a leader in integrated facility solutions, as described in Slide 11, we must also address areas that have impeded our growth. We've embarked on a number of changes to reconfigure ABM's business model by focusing on a set of strategic levers, which impact our operations and the enterprise itself to provide a context via the factors impacting the near-term horizon for companies in the facility service market and ABM. We have uncertain economic growth. We have market pressures and pricing pressures and, last, we have consolidation of services and geography throughout the -- across the country and the globe.
Operations. ABM's operations model has been trade-based and servicing our clients globally, regionally and in certain cases, nationally. Operating under this model and expanding primarily through acquisitions over the past 10 years, ABM has achieved a 7.8% compounded annual growth rate for revenue and 11% for adjusted EBITDA in the time period. While these results is basically against some of the economic challenges we face are good, we haven't been able to crack the code of marketing our services across all lines until recently. To drive our OneABM initiative and ensure our clients and prospective clients know the full spectrum of ABM services and capabilities, refilling the following to improve our long-term growth prospects and operational results. Realigning the operational structures to accelerate the OneABM growth strategy by creating a market-based organization; integrating on-site service disciplines; and investing further in our ABM Mobile network and ABM On-Demand, which represents better long-term growth and higher margin opportunities as shown in Slides 12 and 13.
Leading our on-site services is Jim McClure. These services include Janitorial, Security, Parking and on-site facility services. Tracy Price will continue to lead our ABM Mobile, ABM On-Demand and Government businesses. In addition to these business and corporate marketing, Tracy will take responsibility for corporate sales and other growth initiatives. Optimizing service delivery by deploying subject matter experts who collectively ensures standardized service in all virtually diverse client base and maximizing vertical marketing expertise to drive organic growth via targeted vertical segments where the growth and margin profiles are greater than our commercial-based business.
Our recent acquisitions of Air Serv with revenues of approximately $300 million and HHA with revenues of approximately $50 million are examples of investments we are making to increase our share of vertical market with very long-term growth profiles. With Air Serv, we acquired a business with an 11% compounded annual growth rate for organic revenue over the past 5 years and combining with our existing aviation business, demonstrates to client in this vertical our broad range of capabilities. Reasonably, we notified that we're in the final phase of a potential $25 million to $30 million contract by an energy project. It was one of the large U.S.-based air carriers in addition with these other contracts at Glasgow Airport, which is a new location for Air Serv.
Our acquisition of HHA gives us a health care vertical with over $200 million in sales, combined with our existing business. In addition, HHA provides ABM with an expanded portfolio of services and an entry point into a -- the $64 billion hospital market for housekeeping and food service. Organic revenue compound annual growth rate for HHA over the 5 years exceeds 20%, and we believe there will be some sales synergies from the market as well as existing health care clients in Clinical Engineering, Parking and Facility Solutions and enterprise.
The next set of strategic levers we'll be working on, which complements the operational initiative, focuses on our enterprise model. We made a number of critical investments over the past few years in our infrastructure such as operating our information technology systems, further consolidating back-office operations, improving business analytics and introducing biometric timekeeping programs. To create additional efficiencies leading to improved productivity and integrated salable system and processes, we plan on doing the following at the enterprise level: centralize up to 9% of the transactional activity and through the consolidated back-office operations by creating an enterprise service center; increase build analytics and operational support for forecasting and bid preparation; and implement a multifunctional contract management system to automate existing processes, as well as capturing key client information and billing parameters. Together, these processes and system improvements are expected to deliver cost savings annually of $5 million to $7 million once fully implemented over the next 18 to 24 months. For fiscal 2013 though, all of those savings generated will be used to fund additional investments we're making to grow our revenue and expand our vertical markets.
In summary, please turn to Slide 14. Our goal is to market and deliver services. OneABM is well underway. Over the next 2 fiscal years, we will continue to utilize the significant cash flow we've been generating annually by making strategic investments to broaden services, improving client-facing technology, as well as internal analytics, expanding and entering into vertical market with higher growth rates and margins, as well as leveraging a geographical footprint and skill set built over 100 years. We believe ABM is uniquely positioned to become the leader in integrated facility services. We're looking forward to providing an update on our plans and our processes we are making, integrating recent acquisitions early next year when we host our Investor Day. We hope that at this point in time, the fiscal cliff will have been resolved, and with that, the uncertainty and drag on the U.S. economy will be put to rest.
I will now turn the call over back to Jim Lusk. Jim?
