BRUSSELS, BELGIUM – April 30, 2008 – WABCO Holdings Inc. (NYSE: WBC) today reported record Q1 2008 sales of $705 million, up 26 percent over prior year and up 12 percent in local currencies, continuing the Company’s long track record of quarterly growth.

“These results again demonstrate our continued ability to outperform the global commercial vehicle market,” said Jacques Esculier, WABCO Chief Executive Officer. “We outpaced the industry performance in all regions of the world, led by our 36 percent growth in Asia. Commercial vehicle production in Europe, our largest market, grew by 10 percent while our sales increased by 12 percent. Even in North America this quarter, where the market contracted by 27 percent, we succeeded in containing our sales decline to 14 percent.”

WABCO reported Q1 2008 operating income of $83.7 million, up 34 percent over prior year on a U.S. GAAP basis. Performance operating income, which excludes separation and streamlining costs, rose to $91.5 million, up 44 percent over prior year; up 27 percent in local currencies.

WABCO’s U.S. GAAP operating margin in Q1 2008 increased to 11.9 percent, expanding 65 basis points over prior year. Performance operating margin increased to 13.0 percent, expanding 157 basis points over prior year in local currencies.

“Our WABCO Operating System, one of the industry’s most advanced management environments, continues to strengthen our income performance through operational improvements in efficiency and quality across our value chain. It defines our path to continuously improve every aspect of our business, as we pursue global expansion powered by our passion for growth,” said Esculier.

On a U.S. GAAP basis, Q1 2008 net income increased by 53 percent to $61.3 million or $0.91 cents per diluted share from $40.1 million or $0.58 cents per diluted share a year ago. On a performance basis that excludes separation costs, operational streamlining expenses, and one-time and discrete tax items, Q1 2008 net income increased by 52 percent to $70.3 million or $1.04 per diluted share versus $46.4 million or $0.67 cents per diluted share a year ago.

WABCO generated $50.9 million in net cash from operating activities in Q1 2008 and $33.0 million of free cash flow, which was affected by a separation-related tax liability of $11.2 million that was paid in the quarter. Continuing its share buy-back program announced on August 1, 2007, the Company repurchased approximately 700,000 shares for $31.9 million in open market transactions in Q1 2008 and paid $4.7 million in dividends.

Q1 2008 Highlights

In Q1 2008, WABCO started delivery of transmission automation systems for the second generation powershift used in new Mercedes-Benz Actros trucks.

WABCO signed an agreement with China National Heavy Truck Company (CNHTC) in Q1 2008 to supply clutch control systems beginning in 2009. Also in Q1 2008, the company was awarded a vacuum pump contract for diesel applications by a U.S. customer starting in 2010.

In February 2008, WABCO introduced OnGuard™, a breakthrough technology and the world’s first collision mitigation system with active braking for commercial vehicles. OnGuard is targeted to be available in Q3 2008 as a factory-installed option at several original equipment manufacturers.

WABCO’s factory in Qingdao, China received the highest grade for quality and processes by one of our major European customers in Q1 2008, distinguishing WABCO as this customer’s first A-rated supplier in China.

During Q1 2008, WABCO commenced extension of its existing test track located near Hanover, Germany. The extension will increase WABCO’s capabilities to conduct development testing on sophisticated vehicle stability control systems. “We anticipate that the European Union will mandate Electronic Stability Control (ESC) technology starting in 2010, contributing further to road safety,” said Dr. Christian Wiehen, WABCO Vice President, Product Development. “WABCO pioneered ESC for commercial vehicles in 2001 and we have driven ESC innovation ever since.”

As part of its worldwide partnership with customers to develop and validate their products ahead of market introduction, WABCO has two other proprietary test tracks. One is located at the Arctic Circle in Rovaniemi, Finland where Company engineers and technicians completed approximately 1,300 person-days of extreme-condition winter tests in Q1 2008. The other test track is located near Chennai, India and owned by WABCO-TVS (India) Ltd.

Updated Full-Year 2008 Projections

Raising its full-year 2008 projections, WABCO expects sales growth between 9 and 12 percent, in local currencies, for the year, up 1 percent from its previous guidance. WABCO has also raised its full-year U.S. GAAP and performance diluted EPS projections. The revised range for U.S. GAAP diluted EPS is $3.56 to $3.71; the revised range for performance diluted EPS is $3.91 to $4.05, up $0.18. EPS on a performance basis excludes separation costs, operational streamlining expenses, and one-time and discrete tax items.

“With outstanding progress in the first quarter and markets continuing to remain strong, we are confident in our raised projections for the full year,” said Esculier.

Forward-Looking Statements

Comments in this document contain certain forward-looking statements, which are based on management’s good faith expectations and beliefs concerning future developments. Actual results may differ materially from these expectations as a result of many factors. These factors include, but are not limited to, the risks and uncertainties described in the “Risk Factors” section and the “Forward Looking Statements” section of WABCO’s Form 10-K, as well as in the “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Information Concerning Forward Looking Statements” section of WABCO’s Form 10-Q Quarterly Reports. WABCO does not undertake any obligation to update such forward-looking statements. All market and industry data are based on Company estimates.

Non-GAAP Financial Measures

To facilitate understanding of Q1 2008 results, several tables follow this news release. Sales excluding the effects of foreign exchange are a non-GAAP financial measure. Additionally, operating income, net income and net income per diluted share on a “performance basis” are non-GAAP financial measures that exclude separation costs,

operational streamlining expenses, and one-time and discrete tax items, as applicable. Lastly, “free cash flow” presents our net cash provided by operating activities less net cash used in investing activities. These measures should be considered in addition to, not as a substitute for, GAAP measures. Management believes that presenting these non-GAAP measures is useful to shareholders because it enhances their understanding of how management assesses the operating performance of the Company’s business. Certain non-GAAP measures may be used, in part, to determine incentive compensation for current employees.
