Infosys is expected to post robust earnings results for the second straight quarter, outperforming its peers on "healthy client mining and absence of client specific issues."

Analysts expect the India's second largest IT firm to record a sequential revenue growth of 6.2% for the July-September quarter in rupee terms, while the figures for its rivals Tata Consultancy Services (TCS), Wipro and HCL Technologies are estimated to be 5.8%, 5.3% and 3.2%, respectively, Business Standard reported.

Although TCS is projected to post decent numbers for the quarter, investors are likely to focus on its revenue growth from Diligenta and energy businesses, which have weighed on the India's largest IT firm's earnings in the past few quarters.

Revenues of Wipro and HCL Technologies are likely to witness pressure from unfavourable cross currency movements in the quarter. Last week, India's fourth largest IT firm, HCL Tech, had warned that its revenue would be hit by currency fluctuations in the July-September quarter.

"During this quarter, revenues to be reported in US dollar would have an adverse impact of 80 basis points on account of sharp depreciation of multiple currencies against US dollar," HCL Tech said in a statement to the BSE.

The revenue growth for the top four domestic IT firms is estimated at come between 1.8% to 4.6% in constant currency terms, with Infosys leading the pack and HCL Tech remaining as the laggard.

Further, TCS and Infosys are expected to show a 50-100 basis points improvement in margins helped by rupee depreciation and a decline in visa costs. On the other hand, salary hikes are likely to weigh on the margins of both Wipro and HCL Technologies.

While TCS's profit is expected to see a growth of 7% sequentially, Infosys is likely to record a net profit of 6.4% in the quarter. Wipro is expected to announce flat growth in net profit, while HCL Tech's profit is forecast to dip by 3.2% sequentially on the back of client-related issue.

Recently, HCL warned that its earnings would be negatively impacted by some client-related issue. It estimates $20 million revenue loss from differences with one of its major clients.

Besides, a muted guidance given by global software giant Accenture for its next financial year has raised doubts over Indian IT companies posting a double-digit growth in the coming quarters. Accenture gave a much lower revenue guidance of 5-8% for the financial year ending August 2016 compared to its revenue growth of 11% recorded in the previous year.
