Key Energy Services announced it has reached a definitive agreement to acquire Edge Oilfield Services and Summit Oilfield Services. (collectively “Edge”) for consideration of approximately $300 million, consisting of approximately 7.5 million shares of Key common stock and approximately $164 million in cash, which is subject to working capital and other adjustments at closing. Key anticipates funding the cash portion of the consideration from available cash and borrowings under its credit facility. In addition to the $300 million of consideration, Key has also agreed to reimburse or fund up to $40 million of Edge’s pre-closing capital expenditures related to Edge’s expansion into the Eagle Ford shale, which began generating revenue this quarter.

Edge primarily rents frac stack equipment used to support hydraulic fracturing operations and the associated flow back of frac fluids, proppants, oil and natural gas. It also provides well testing services, rental equipment such as pumps and power swivels, and oilfield fishing services. Following the close, Edge’s results will be reflected within Key’s existing Fishing & Rental Services line of business, which is included in its U.S. reportable segment.

Key’s chairman, president and CEO, Dick Alario, stated, “Edge’s high performance frac stack equipment enjoys strong growth opportunities, particularly in unconventional shale markets. Furthermore, its high revenue and profit per employee fits with our overall investment strategy and should prove beneficial, especially in today’s tight labor market.”

Alario continued, “Edge’s existing business currently generates an annual EBITDA run rate of approximately $65 million. With the expansion into the Eagle Ford that is already underway, Edge believes its EBITDA run rate will be approximately $80 million by year-end 2011. We anticipate Edge’s business to be accretive to Key’s margins and earnings beginning in 2011. With Edge’s experienced oilfield industry veterans, we intend to aggressively expand Edge’s service offerings across Key’s existing infrastructure, particularly in emerging unconventional shale markets.”

Edge’s CEO, Darrell Brewer, stated, “We look forward to becoming a part of Key, a high quality, industry leading company, where we can better leverage our business potential via Key’s extensive U.S. footprint and financial resources and where our employees will continue to enjoy a bright future.”

Greenhill & Co. acted as advisor to Key Energy Services for this transaction. Tudor, Pickering, Holt & Co. Securities acted as advisor to Edge Oilfield Services and Summit Oilfield Services.

The closing of this transaction, which is expected to occur this quarter, is subject to customary conditions including the expiration or termination of the waiting period under the Hart-Scott-Rodino Act.
