Syntel Reports First Quarter 2016 Financial Results

Highlights:

TROY, Mich. – April 21, 2016 – Syntel, Inc. (Nasdaq:SYNT), a global provider of digital transformation, information technology and knowledge process services to Global 2000 companies, today announced financial results for the first quarter, ended March 31, 2016.

First Quarter Financial Highlights

Syntel’s revenue for the first quarter increased nine percent to $241.4 million from $220.6 million in the prior-year period, and declined five percent from $254.6 million in the fourth quarter of 2015. During the first quarter, Banking and Financial Services accounted for 50.3 percent of total revenue, with Retail, Logistics and Telecom at 16.4 percent, Healthcare and Life Sciences at 15.9 percent, Insurance at 12.7 percent, and Manufacturing at 4.7 percent.

The Company’s gross margin was 37.2 percent in the first quarter, compared to 35.7 percent in the prior-year period and 41.8 percent in the fourth quarter of 2015. Selling, General and Administrative (SG&A) expenses were 12.3 percent of revenue in the first quarter, compared to 16 percent in the prior-year period and 11 percent in the previous quarter.

The first quarter income from operations was 24.9 percent of revenue as compared to 19.7 percent in the prior-year period and 30.8 percent in the fourth quarter. The sequential decline in operating margin during the first quarter primarily reflects the impact of lower revenue, higher compensation-related expense and currency-related balance sheet translations.

Net income for the first quarter was $53.1 million or $0.63 per diluted share, compared to $40 million or $0.48 per diluted share in the prior-year period and net income of $74.2 million or $0.88 per diluted share in the fourth quarter of 2015.

During Q1, Syntel spent $3.4 million in CAPEX, largely in support of campus infrastructure, and finished the quarter with cash and short-term investments of $1.08 billion. The Company ended the quarter with 24,496 employees globally.

Operational Highlights

“Our customers remain focused on transforming their businesses, however, the market volatility seen during the first quarter led to elongated decision cycles on full-year budgets,” said Syntel CEO and President Nitin Rakesh. “There is a clear need for partners who can help companies execute strategic initiatives while also managing the cost of ownership of IT investments across their organizations. Syntel’s capabilities in digital enablement and modernization and our SyntBots recursive automation platform are helping customers strike the right balance between these competing priorities.”

“On the strength of our offerings, we expanded our footprint with strategic customers last quarter and identified additional ways to build on these critical relationships. Syntel’s ongoing investments in domain-centric capabilities underscore our commitment to the long-term success of our customers,” said Rakesh. “While growth in our insurance industry group remained weak this quarter, the health of the underlying pipeline continues to give us confidence that this segment will begin to recover in a few quarters.”

2016 Guidance

Based on current visibility levels and an exchange rate assumption of 66.50 Indian rupees to the dollar, the Company currently expects 2016 revenue of $1,010 million to $1,040 million and EPS in the range of $2.55 to $2.80.
