Accenture Plc, the world’s second-biggest technology-consulting company, said the crisis in Ukraine is unsettling customers, adding to the company’s challenges in emerging markets.

“We are carefully monitoring the recent geopolitical developments in Eastern Europe, which are introducing the additional level of uncertainty in the marketplace,” Chairman Pierre Nanterme said Wednesday on a conference call. The global economic environment “frankly continues to be challenging, especially in the emerging markets,” he said.

Accenture, based in Dublin, has been counting on growth in emerging markets to help make up for sluggish growth in Western Europe and the U.S. Russia’s annexation of Crimea, in Ukrainian territory, has drawn sanctions from the U.S. and Europe.

Shares of Accenture dropped 6.5 percent to $77.61 at 2 p.m. in New York. The company got 40 percent of its $7.13 billion in sales last quarter from Europe, the Middle East and Africa. Bob Christie, a spokesman for Accenture, declined to comment on Nanterme’s remarks.
