WABCO Reports Q1 2011 Results; Posts 36% Organic Sales Growth; Delivers

Record Profitability; Raises Guidance for 2011

BRUSSELS, Belgium, April 29, 2011 – WABCO Holdings Inc. (NYSE: WBC), a global technology leader and tier-one supplier to the commercial vehicle industry, today reported Q1 2011 sales of $678 million, up 36 percent in local currencies from a year ago and up 38 percent on a U.S. GAAP basis, reflecting an industry that continues to rebound globally.

“Q1 2011 marked another milestone of outstanding results as we substantially grew sales by 36 percent in local currencies while at the same time delivering an incremental operating profit margin at the robust level of 26 percent, thus breaking new ground in profitability,” said Jacques Esculier, WABCO Chairman and Chief Executive Officer. “Our first quarter results are in line with WABCO’s strongly rising performance throughout 2010 as we continue to demonstrate our ability to grow revenues, gain productivity and deliver remarkable incremental profitability.”

“During Q1 2011, the commercial vehicle industry further propelled its recovery as Europe, North America, South America and Asia drove double-digit growth in production of trucks and buses, and WABCO continued to outperform all regional markets through increased adoption of WABCO content per vehicle,” said Esculier. “Indeed, our truck and bus sales increased by 72 percent in Europe, 43 percent in North America, 23 percent in South America and 19 percent across Asia.”

“Particularly in China, India and Brazil, which accounted for two thirds of the world’s truck and bus production during Q1 2011, we see significant growth in WABCO content per vehicle propelled by our continuous flow of investments in local capabilities as well as our successful leveraging of new technologies,” said Esculier.

“Also in Q1 2011, we generated $159 million in aftermarket revenues, up 12 percent year on year, resulting in a new all-time quarterly record. This solid performance is based on a return to normal levels of fleet utilization, market growth and our continued execution of WABCO’s aftermarket strategies initiated several years ago,” said Esculier.

WABCO reported Q1 2011 performance operating income of $90.2 million, up from $44.5 million a year ago, while operating income was $88.1 million on a U.S. GAAP basis, up from $43.1 million a year ago. This strong increase in performance operating income in Q1 2011 represents an incremental operating margin of 26 percent, excluding the impact from foreign exchange translation.

WABCO reported Q1 2011 performance operating margin of 13.3 percent, up from 9.1 percent a year ago, while operating margin was 13.0 percent on a U.S. GAAP basis, up from 8.8 percent a year ago.

WABCO reported Q1 2011 performance net income of $77.0 million or $1.12 per diluted share, up from $33.6 million or $0.51 per diluted share a year ago, and Q1 2011 U.S. GAAP net income of $114.7 million or $1.66 per diluted share, up from $30.7 million or $0.47 per diluted share a year ago.

The $37.7 million difference between performance net income and U.S. GAAP net income in Q1 2011 is predominantly driven by provision releases due to the favorable resolution of separation related indemnification liabilities and tax audit settlements.

WABCO generated $71.0 million in net cash from operating activities in Q1 2011, resulting in free cash flow of $61.3 million, excluding payments of $4.7 for streamlining and separation activities, which is a conversion rate of 80 percent of performance net income.

“Q1 2011 marks yet another consecutive quarter of results that show WABCO’s reliable ability to transform market growth into outstanding profitability,” said Esculier. “This quarter, WABCO delivered operating margin of 13.3 percent on a performance basis, resulting in a new all-time record. We also delivered net income of $77.0 million on a performance basis, the company’s highest ever quarterly amount.”

“WABCO’s Operating System, one of our industry’s most advanced management environments, continues to enable fast and flexible responses to market growth as it generated $15.2 million of materials and conversion productivity in Q1 2011. Gross materials productivity represented 5.7 percent of total materials cost but, as expected, the impact of higher prices for materials due to commodity inflation reduced net materials productivity to 3.2 percent,” said Esculier. “In Q1 2011, we generated 5.5 percent of conversion productivity, another achievement in operating performance, particularly during a period of high growth.”

Forward-Looking Statements

This document contains certain “forward-looking statements” as defined by the Private Securities Litigation Reform Act of 1995 that are based on management’s good faith expectations and beliefs concerning future developments. Statements preceded by, followed by or that otherwise include the words “believes,” “expects,” “anticipates,” “strategies,” “prospects,” “intends,” “projects,” “estimates,” “plans,” “may increase,” “may fluctuate,” and similar expressions or future or conditional verbs such as “will,” “should,” “would,” “may” and “could” are generally forward looking in nature and not historical facts. Actual results may differ materially from these expectations as a result of many factors. These factors include, but are not limited to, the actual level of commercial vehicle production in our end markets, adverse developments in the business of our key customers, pricing changes to our supplies or products, and the other risks and uncertainties described in the “Risk Factors” section and the “Information Concerning 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.

Non-GAAP Financial Measures

To facilitate the understanding of Q1 2011 results, several tables follow this news release. Sales excluding the effects of foreign exchange, incremental gross and operating margin and EBIT are non-GAAP financial measures. Additionally, operating income, EBIT, net income and net income per diluted share on a “performance basis” are non-GAAP financial measures that exclude separation and streamlining items, and discrete and other one-time tax items, as applicable. Free cash flow presents our net cash provided by operating activities less net cash used for purchases of property, plant, equipment, and computer software. 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.
