MATADOR RESOURCES COMPANY ANNOUNCES CLOSING OF PUBLIC OFFERING OF COMMON STOCK

DALLAS, September 10, 2013 - Matador Resources Company (NYSE: MTDR) (“Matador”)announced today that it has closed the previously announced underwritten public offering of 9,775,000 shares of its common stock (which includes 1,275,000 shares issued pursuant to the underwriters' exercise of their option to purchase additional shares). Matador received net proceeds from this offering of approximately $141.4 million after deducting underwriters' discounts and commissions and estimated offering expenses.

Matador intends to use the net proceeds from this offering primarily to fund a portion of its capital expenditures, including for the addition of a third rig to its current two-rig drilling program, allowing Matador to operate two drilling rigs for the development of its acreage in the Eagle Ford shale play and one drilling rig for the exploration and development of its acreage in the Wolfcamp and Bone Spring plays in the Permian Basin. Matador also intends to use net proceeds from this offering to fund the acquisition of additional acreage in the Eagle Ford shale, the Permian Basin and the Haynesville shale and for other general working capital needs. Pending such uses, Matador intends to repay outstanding borrowings under its revolving credit facility, which amounts may be reborrowed in accordance with the terms of that facility.
