Highlights:

TROY, Mich. – February 13, 2014 – Syntel, Inc. (NASDAQ: SYNT), a global information technology services and Knowledge Process Outsourcing (KPO) company today announced financial results for the fourth quarter and full year, ended December 31, 2013.

Fourth Quarter Financial Highlights

Syntel’s revenue for the fourth quarter increased 19 percent to $223.3 million, compared to $187.8 million in the prior-year period, and increased six percent sequentially from $209.9 million in the third quarter of 2013. During the fourth quarter, Applications Outsourcing accounted for 78 percent of total revenue, with Knowledge Process Outsourcing (KPO) at 15 percent, e-Business contributing six percent and TeamSourcing at one percent.

The Company’s gross margin was 47.1 percent in the fourth quarter, compared to 45.2 percent in the prior-year period and 46.6 percent in the third quarter of 2013. Selling, General and Administrative (SG&A) expenses were 13.3 percent of revenue in the fourth quarter, compared to 15 percent in the prior-year period and 10.7 percent in the previous quarter.

The fourth quarter income from operations was 33.7 percent of revenue as compared to 30.2 percent in the prior-year period and 35.9 percent in the third quarter. The sequential decline in operating margin primarily reflects the impact of currency-related balance sheet translations, and higher employee headcount and compensation expense.

Net income for the fourth quarter was $66.3 million or $1.58 per diluted share, compared to $49.9 million or $1.19 per diluted share in the prior-year period and net income of $59.4 million or $1.42 per diluted share in the third quarter of 2013.
