Hi-Crush Partners LP Reports First Quarter 2013 Results

Houston, Texas, May 14, 2013 - Hi-Crush Partners LP (NYSE: HCLP), “Hi-Crush” or the “Partnership”, today reported net income of $10.8 million, or $0.40 per limited partner unit, for the first quarter of 2013. Net income per limited partner unit does not include $0.14 per common and subordinated unit related to the $3.75 million distribution earned under the preferred interest from Augusta. This distribution was paid in May 2013 and will be included in the Partnership’s net income in second quarter 2013.

Overview of Financial Results

“We are pleased with our performance in the first quarter of 2013,” said Robert Rasmus, Co-Chief Executive Officer of Hi-Crush. “We continued to benefit from rising proppant intensity caused by increased drilling and completion efficiencies and an increase in the average number of frac stages per well. These trends, combined with a renewed push towards 24-hour operations, continue to support strong demand for our premium products. We saw increasing demand as we moved through the first quarter and see signs for continued strength in demand in the near-term.”

Revenues for the quarter ended March 31, 2013 totaled $19.6 million and reflect an average selling price for all tons sold in the quarter of $62.76 per ton. Hi-Crush sold 312,730 tons of frac sand for the quarter ended March 31, 2013. For the quarter ended March 31, 2013, distributable cash flow was $14.5 million and earnings before interest, taxes, depreciation and amortization (“EBITDA”) was $11.4 million.

“Our customers met their contract terms in the first quarter and volumes were trending up throughout the quarter. This, combined with our sales under spot arrangements, resulted in our Wyeville plant shipping a record number of tons in the month of March. The first quarter is our second highest quarter for tons delivered and sold since building the plant,” said James Whipkey, Co-Chief Executive Officer of Hi-Crush.

On April 17, 2013, Hi-Crush declared its first quarter cash distribution of $0.475 per unit for all common and subordinated units. This amount corresponds to the minimum quarterly cash distribution of $0.475 per unit, or $1.90 on an annualized basis, and will be paid on May 15, 2013 to unitholders of record on May 1, 2013.

Preferred Interest in Augusta Facility

On January 31, 2013, Hi-Crush entered into an agreement with Hi-Crush Proppants LLC (the “Sponsor”) to acquire an interest in Hi-Crush Augusta LLC (“Augusta”), the entity that owns the Sponsor’s Augusta raw frac sand processing facility, for $37.5 million in cash and 3.75 million of newly issued convertible Class B units in Hi-Crush. The preferred interest in Augusta entitles the Partnership to a preferred distribution of $3.75 million per quarter, or $15 million annually. The first preferred distribution of $3.75 million from Augusta was paid to the Partnership on May 10, 2013. The amount is not reflected in the Partnership’s net income because the investment in Augusta is accounted for under the cost method. In accordance with that method, any distributions earned under the preferred interest are not recognized as income until the cash is actually received by the Partnership.

Customer Contract

Hi-Crush also announced an amendment to a supply agreement with one of its customers. The terms of the amendment cover the period from April 1, 2013 to December 31, 2013 and involve a price reduction under the supply agreement in exchange for an increase in contracted frac sand volume at the Wyeville facility for that period. The increase will be offset by a decrease in volume sold to the customer from the Augusta facility operated by the Sponsor. As a result of the amendment, all volumes at the Wyeville facility will be fully contracted. Hi-Crush estimates this amendment will impact the weighted average price for tons sold under its long-term contracts by less than 10% in 2013.
