WNS Announces First Quarter Fiscal 2010 Earnings;
Reaffirms Guidance for Fiscal 2010

Quarterly Revenue Increases 11%; Revenue Less Repair Payments Increases 20%
Over the Corresponding Quarter in the Prior Fiscal Year

NEW YORK and MUMBAI, August 5, 2009 — WNS (Holdings) Limited (WNS) (NYSE: WNS), a leading provider of global business process outsourcing (BPO) services, today announced results for the fiscal first quarter 2010 ended June 30, 2009 and reaffirmed its guidance on revenue less repair payments and adjusted net income (or net income attributable to WNS shareholders excluding amortization of intangible assets, share-based compensation, related fringe benefit taxes and loss attributable to noncontrolling interest) for fiscal 2010.

Revenue for the fiscal first quarter 2010 of $136.7 million represented an increase of 11.2% over the corresponding quarter in the prior fiscal year, while revenue less repair payments at $98.5 million increased 19.8% over the corresponding period in the prior fiscal year. The revenue less repair payments growth was largely the result of the acquisition of Aviva Global Services (AGS), which WNS acquired in July 2008.

“We had a strong quarter on all dimensions. We continued to see client additions and organic growth during this past quarter,” said Neeraj Bhargava, Group Chief Executive Officer. “As we expand our client base and increase the number of top-tier logos on our client roster, we are better positioning the company for long-term success in the BPO market.”

Net income attributable to WNS shareholders for the fiscal first quarter 2010 was $1.0 million compared to $3.3 million during the corresponding quarter in the prior fiscal year. The net income attributable to WNS shareholders in the current quarter was impacted by amortization charges from the acquisition of AGS and higher foreign exchange losses.

Adjusted net income was $12.6 million, an increase of 53% over the corresponding quarter in the prior year. The primary drivers of this increase were revenue growth from new and existing clients, tighter cost management, improved scale benefits and increased income from WNS’ acquisitions. This increase was partially offset by higher foreign exchange losses.

WNS recorded a basic income per ADS of $0.02 for fiscal first quarter 2010. Adjusted income per ADS (or net income attributable to WNS shareholders per ADS excluding amortization of intangible assets, share-based compensation, related fringe benefit taxes and loss attributable to noncontrolling interest) was $0.30 for the quarter.

“WNS continued to improve profitability in the first quarter. We have made great progress on our cost management initiatives and are running very efficiently from an operational perspective,” said Alok Misra, Group Chief Financial Officer. “We anticipate that FX losses will roll off during the year and that we will continue to realize cost synergies from our acquisitions, which should provide additional support for our bottom line.”

Key Business Developments

In the past quarter, the following are WNS’ key developments:

• WNS made a voluntary prepayment of $5 million on the $200 million term loan associated with the AGS acquisition in April 2009 and another in July 2009, in addition to the scheduled repayment of $20 million, also in July 2009.

• WNS reorganized its industry-specific capabilities to form a new core functional service capability called the Global Transformation Practice (GTP) and appointed Daniel L. Wollenberg as the head of the GTP.

• Aviva Global Services (Management Services) Private Limited (AVIVA) has agreed to increase the minimum committed volume of business to WNS from 3,000 to 3,300 full time employees (FTEs) from March 2010 until July 2011, and to 3,250 FTEs from August 2011 until January 2012. Thereafter, the minimum committed volume of business under the agreement will return to the original 3,000 FTEs.

• WNS has agreed to pay AVIVA approximately £3.18 million for liabilities inherited as part of the AGS acquisition in July 2008 in 18 equal monthly installments commencing December 2009.

Fiscal 2010 Guidance

WNS reiterated the following guidance for the fiscal year ending March 31, 2010:

• Revenue less repair payments is expected to be between $385 million and $390 million. This assumes an average USD to GBP range of 1.40 to 1.45 for the full year.

• Adjusted net income (or net income attributable to WNS shareholders excluding amortization of intangible assets, share-based compensation, related fringe benefit taxes and loss attributable to noncontrolling interest) is expected to range between $50 million and $52 million. This assumes an average USD to INR rate of 49 to 50 for the full year.

“The British Pound has started to move in our favor over the past few months. If the currency rates maintain their current trajectory, we will have a nice tailwind for the rest of the year and could conceivably beat the top end of our guidance range,” continued Misra. “As we demonstrated by pre-paying an additional $5 million on our term loan in July, we remain on track to generate $60 million in free cash in fiscal 2010.”

About Non-GAAP Financial Measures

For financial statement reporting purposes, the company has two reportable segments: WNS Global BPO and WNS Auto Claims BPO. In the auto claims segment, which includes WNS Assistance and Chang Limited, WNS provides claims-handling and accident-management services, in which it arranges for automobile repairs through a network of third-party repair centers. In its accident-management services, WNS acts as the principal in dealings with the third-party repair centers and clients.

In order to provide accident-management services, the Company arranges for the repair through a network of repair centers. Repair costs are invoiced to customers. Amounts invoiced to customers for repair costs paid to the automobile repair centers are recognized as revenue. The Company uses revenue less repair payments for “fault” repairs as a primary measure to allocate resources and measure segment performance. Revenue less repair payments is a non-GAAP measure which is calculated as revenue less payments to repair centers. For “non fault repairs,” revenue including repair payments is used as a primary measure. As the Company provides a consolidated suite of accident management services including credit hire and credit repair for its “Non fault” repairs business, the Company believes that measurement of that line of business has to be on a basis that includes repair payments in revenue.

The Company believes that the presentation of this non-GAAP measure in the segmental information provides useful information for investors regarding the segment’s financial performance. The presentation of this non-GAAP information is not meant to be considered in isolation or as a substitute for the Company’s financial results prepared in accordance with US GAAP.
