MarkWest Energy Partners, L.P. Reports 2006 Second Quarter Results
DENVER—August 3, 2006—MarkWest Energy Partners, L.P. (AMEX: MWE) today reported net income of $14.1 million for the three months ended June 30, 2006, compared to net income of $0.7 million for the second quarter of 2005. For the six months ended June 30, 2006, the Partnership reported net income of $28.0 million compared to net income of $4.9 million for the six months ended June 30, 2005.
As a Master Limited Partnership, cash distributions to limited partners are largely determined based on Distributable Cash Flow (DCF). For the three months ended June 30, 2006, DCF was $29.7 million, compared to $7.6 million for the three months ended June 30, 2005. For the six months ended June 30, 2006, DCF was $53.3 million, compared to $20.0 million for the six months ended June 30, 2005. A reconciliation of DCF to our most directly comparable GAAP financial measure, net income, is provided at the end of this press release.
On July 26, 2006, the board of directors of the general partner of MarkWest Energy Partners, L.P., declared the Partnership’s quarterly cash distribution of $0.92 per unit for the second quarter of 2006. This is an increase of $0.05 per unit, or 5.8% over the previous quarter distribution and an increase of $0.12 per unit, or 15.0% over the second quarter 2005 distribution. The increase also represents the twelfth increase in the fifteen quarters of operation since our first full quarter of operation and also represents a compound annual growth rate of 15% for our distributions to our unitholders. The second quarter distribution will be paid on August 14, 2006 to unitholders of record as of August 7, 2006.
“We are pleased to report record earnings and distributable cash flow,” said Frank Semple, President and CEO. “These results clearly reflect the benefits of our recent acquisitions as well as the organic growth from our existing businesses. Last week our board approved a $0.05 per unit distribution increase. The $0.92 per unit quarterly distribution represents a 15% increase over the second quarter 2005 and results in a very strong 1.6 times distribution coverage ratio (including the associated GP and IDR requirements). We are also pleased to announce the extension of our hedging program through 2007 and the increase in our 2006 capital budget for internal growth projects from the previously announced $48 million to $92 million, with approximately $24 million having been spent through June 30. While we will continue to aggressively pursue accretive acquisitions, what is most exciting to me about our performance is
that we have now reached the point where organic growth alone, supported by internally generated cash flow, should enable us to achieve our stated goal of 10 percent annual per unit distribution growth for the foreseeable future.”
The change in net income in the second quarter of 2006, compared to the same period for 2005, was primarily attributable to:
· The second quarter of 2006 compared to the same period in 2005 was characterized by improved results of operations at every business segment. Segment operating income increased by $27.9 million. We completed the Javelina acquisition on November 1, 2005, and these assets contributed $12.2 million of segment operating income. For our Southwest Business Unit, consisting of our East Texas, Oklahoma and Other Southwest segments, our combined operating income increased by $12.8 million. A portion of this increase was due to the Carthage Gas Plant and NGL pipeline beginning operations in the first quarter of 2006. In addition, we experienced increased gathering volumes at each of our Carthage, Appleby and Western Oklahoma gathering systems as well as higher NGL prices, which had a positive effect on second quarter earnings.
· For our investment in Starfish Pipeline Company, we reported equity income of $1.2 million and accrued a partial insurance recovery of $1.3 million (included in miscellaneous income), an increase of $1.6 million compared to 2005.
· Selling, general and administrative expense increased by $2.7 million. This is related to several factors including a $0.9 million one-time charge to terminate the old headquarters lease; labor costs related to additional personnel from the Partnership’s growth; higher insurance premiums; and reduced professional fees. Non-cash compensation expense attributable to the Participation Plan and Phantom units increased by $0.6 million, from $1.1 million to $1.7 million.
· Consistent with our previous announcements that we would not be applying hedge accounting treatment for these items, we reported a mark-to-market loss of $6.4 million for our 2006/2007 derivative instruments. This is a non-cash adjustment, and as such does not affect distributable cash flow. We also reported realized losses of $0.5 million for the quarter, and as a result derivative activity decreased net income by $6.9 million for the period.
· Interest expense (including amortization of deferred financing costs, a component of interest expense) was $6.5 million higher in 2006 over 2005 respectively, primarily attributable to higher debt levels associated with the Javelina and Starfish acquisitions and related financing activities.
The Partnership will host a conference call on Tuesday, August 8, 2006, at 2:00 p.m. (MDT) to review its 2006 second quarter earnings.
