Blake DeBerry, Dril-Quip’s President and CEO, stated, “We are pleased with our first quarter 2015 results as both revenue and gross margins exceeded our expectations in the face of difficult industry conditions.

Additionally, we believe that our strong balance sheet and free cash flow during 2015 will allow us to enhance shareholder value through both stock repurchases and potential M&A activity, should attractive opportunities arise.”

Based upon current market conditions, the Company expects its earnings per diluted share for the second quarter of 2015 to approximate $1.15 to $1.25 and its earnings per diluted share for the full year to approximate $4.60 to $4.80, excluding any unusual items and foreign currency gains and losses.
