WABCO Reports Q1 2013 Results; Delivers Solid Performance in Continued

Challenging Market; Upgrades Guidance for 2013

BRUSSELS, Belgium, April 25, 2013 – WABCO Holdings Inc. (NYSE: WBC), a global technology leader and tier-one supplier to the commercial vehicle industry, today reported Q1 2013 sales of $644.7 million, down 0.7 percent in local currencies from a year ago and down 1.9 percent in U.S. dollars, reflecting a continued challenging market.

“WABCO opens 2013 with a solid first quarter performance. Against the backdrop of a further 10 percent decline in global commercial vehicle production, WABCO’s revenues dipped by only 0.7 percent, helped by a new quarterly record of $171 million in aftermarket revenues. This result reflects WABCO’s ongoing ability to outperform its markets,” said Jacques Esculier, WABCO Chairman and Chief Executive Officer.

“Furthermore, WABCO’s Operating System, one of our industry’s most advanced management environments, continues to power excellence in execution across our organization, delivering new quarterly records for productivity and gross profit margin,” said Esculier.

WABCO reported Q1 2013 performance operating income of $87.6 million versus $91.3 million a year ago, and operating income was $81.7 million on a U.S. GAAP basis versus $89.5 million a year ago.

WABCO’s performance operating margin for Q1 2013 was 13.6 percent, down from 13.9 percent a year ago, and operating margin was 12.7 percent on a U.S. GAAP basis, down from 13.6 percent a year ago.

For Q1 2013, WABCO reported performance net income attributable to the company of $74.9 million or $1.17 per diluted share versus $77.4 million or $1.17 per diluted share a year ago, and Q1 2013 U.S. GAAP net income attributable to the company of $73.7 million or $1.15 per diluted share versus $89.2 million or $1.34 per diluted share a year ago.

During Q1 2013, WABCO generated $64.0 million in net cash from operating activities, resulting in free cash flow of $49.4 million, excluding payments of $5.8 million for streamlining and separation activities. This resulted in a conversion rate of 66 percent of performance net income attributable to the company which was seasonally affected by tax and incentive compensation payments.

“WABCO generated a total of $18.8 million of productivity, based on savings of 5.0 percent of gross material costs and 5.9 percent of conversion costs for the quarter,” said Esculier. “This all-time quarterly record further demonstrates WABCO’s ability to optimize resources and flex capacity to address changes in market demand.”

Since June 2011, WABCO has repurchased 7,797,096 shares for $431.4 million in open market transactions as of March 31, 2013. WABCO is authorized to repurchase up to $368.6 million of additional shares through December 31, 2014.

“WABCO’s continued outperformance of the global market, in combination with new record achievements in productivity for the quarter, marks Q1 2013 as another successful milestone on our path to deliver outstanding value for our shareowners,” said Esculier.

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 2013 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 attributable to the company and net income attributable to the company 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.
