DRIL-QUIP, INC. ANNOUNCES RESULTS FOR FIRST QUARTER 2016

HOUSTON, April 26, 2016 — Dril-Quip, Inc. (NYSE: DRQ) today announced net income of $36.8 million, or $0.97 per diluted share, for the three months ended March 31, 2016, versus net income of $53.7 million, or $1.38 per diluted share, for the first quarter of 2015. The first quarter 2016 results were favorably impacted by an after-tax foreign exchange gain of $5.4 million, or $0.14 per diluted share, as compared to an after-tax foreign exchange gain of $4.8 million, or $0.12 per diluted share, during the first quarter of 2015. In addition, total revenues were $166.6 million during the quarter ended March 31, 2016 compared to $226.0 million for the same period in 2015.

The Company’s backlog at March 31, 2016 was approximately $522 million, compared to its March 31, 2015 backlog of approximately $1.1 billion and its December 31, 2015 backlog of approximately $685 million.

Blake DeBerry, Dril-Quip’s President and CEO, stated, “Despite the ongoing difficult and challenging market conditions existing in our industry, we are pleased to report that both gross margins and earnings per share results exceeded our expectations for the quarter.

“Continued weak and volatile oil prices, leading to declining capital expenditure budgets for our customers, resulted in disappointing booking levels during the period. Unfortunately, uncertainties persist regarding our bookings and our book-and-ship business for the remainder of the year.

“Looking forward, we continue to believe that our balance sheet, highlighted by a strong cash position and zero debt, leaves us well-positioned to take advantage of opportunities which may arise, whether in the current climate or when the market rebounds. The Company intends to continue its strategy of investing counter cyclically through the pursuit of attractive acquisition candidates, the repurchase of stock through our stock buy-back program and our research and development efforts to benefit the Company in the long term.”

Based upon current market conditions, the Company expects its earnings per diluted share for the second quarter of 2016 to approximate $0.60 to $0.70 and its earnings per diluted share for the full year to approximate $2.45 to $2.65, excluding foreign currency gains/losses or any unusual items.

Dril-Quip is a leading manufacturer of highly engineered offshore drilling and production equipment, which is well suited for use in deepwater, harsh environment and severe service applications.
