WNS Raises Guidance for Fiscal Year 2008

Outlook for Fiscal 2008 Healthy Despite Mortgage Disruption and Currency Appreciation

MUMBAI, INDIA, and NEW YORK, October 3, 2007 — WNS (Holdings) Limited (NYSE: WNS), a leading provider of offshore business process outsourcing (BPO) services, today announced it raised guidance for fiscal 2008 following its rapid response to fluctuations in its U.S. mortgage services business.

“Revenue growth continues to be robust across sectors, and we are confident of finishing this fiscal year on a strong note,” said Neeraj Bhargava, Group Chief Executive Officer. “The overall strength and diversity of our operations have helped us withstand pressure from the mortgage slowdown and appreciation of the Indian Rupee. The WNS team has addressed these issues rapidly while addressing other challenges like attrition and acquiring new business.”

WNS has successfully redeployed or out-placed most of the resources previously dedicated to First Magnus, in addition to deferring ongoing capacity addition to minimize the impact that market conditions in the mortgage industry had on operating income.

WNS has also increased pricing on contracts with new clients and on select contracts with existing clients to help offset the impact of the appreciation of the Indian rupee.

Fiscal 2008 Guidance

WNS raised its Aug. 17, 2007 guidance for fiscal 2008:

• Revenue less repair payments expected to be between $290 million and $295 million. This would represent growth of between 32.0% and 34.3% from fiscal 2007.

• Net income (excluding share-based compensation expense, amortization of intangible assets and fringe benefit taxes on employee stock options) is expected to be between $33 million to $35 million.

• Revised average exchange rate assumptions for the above guidance are 40.00 Indian Rupees to 1 US Dollar and 2.01 US Dollars to 1 Pound Sterling for the rest of the fiscal year.

The detailed guidelines for Fringe Benefit Tax (FBT) on ESOPs are awaited from the Government of India. WNS intends to pass on the incidence of the tax to the employees resulting in a neutral cash impact on the company. The accounting treatment for the same is dependent on the detailed guidelines.

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, 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.

The amounts invoiced to WNS clients for payments made by WNS to third-party repair centers are reported as revenue. As the company wholly subcontracts the repairs to the repair centers, it evaluates its financial performance based on revenue less repair payments to third party repair centers, which is a non-GAAP measure.

WNS believes revenue less repair payments reflects more accurately the value addition of the business process services it directly provides to its clients. 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 U.S. GAAP. WNS revenue less repair payments may not be comparable to similarly titled measures reported by other companies due to potential differences in the method of calculation.
