Halliburton Co., the world’s largest provider of hydraulic fracturing services, said its second- quarter operating profit margin will be negatively impacted by a decline in rigs working in Mexico as the country transitions to a new way of awarding service contracts.

The company had earlier seen a margin close to the mid- teens for the second quarter, Mark McCollum, chief financial officer at Houston-based Halliburton, told investors at an energy conference in Austin, Texas, today.
