DENVER—February 25, 2015—MarkWest Energy Partners, L.P. (NYSE: MWE) (“the Partnership”) today reported quarterly cash available for distribution to common unitholders, or distributable cash flow (DCF), of $201.0 million for the three months ended December 31, 2014, and $706.4 million for the year ended December 31, 2014. DCF for the three months and year ended December 31, 2014 represents distribution coverage of 120 percent and 112 percent respectively.

The fourth quarter distribution of $168.1 million, or $0.90 per common unit, was paid to unitholders on February 13, 2015. The fourth quarter 2014 distribution represents an increase of $0.01 per common unit or 1.1 percent over the third quarter 2014 distribution and an increase of $0.04 per common unit or 4.7 percent compared to the fourth quarter 2013 distribution. As a Master Limited Partnership, cash distributions to common unitholders are largely determined based on DCF. A reconciliation of DCF to net income, the most directly comparable GAAP financial measure, is provided within the financial tables of this press release.

The Partnership reported Adjusted EBITDA for the three months ended December 31, 2014, of $243.0 million and $874.3 million for the year ended December 31, 2014, as compared to $155.5 million and $606.0 million for the three months and year ended December 31, 2013. The Partnership believes the presentation of Adjusted EBITDA provides useful information because it is commonly used by investors in Master Limited Partnerships to assess financial performance and operating results of ongoing business operations. A reconciliation of Adjusted EBITDA to net income, the most directly comparable GAAP financial measure, is provided within the financial tables of this press release.

The Partnership reported income before provision for income tax for the three months and year ended December 31, 2014 of $66.9 million and $202.5 million, respectively. Income before provision for income tax includes non-cash gains associated with the change in fair value of derivative instruments of $63.9 million and $82.1 million for the respective three months and twelve months ended December 31, 2014. Income before provision for income tax includes a non-cash impairment associated with our Northeast segment of $62.4 million for the three and twelve months ended December 31, 2014. Excluding these items, income before provision for income tax for the three months and year ended December 31, 2014 would have been $65.4 million and $182.8 million, respectively.

“2014 was an exceptional year of growth at MarkWest as we completed 16 major processing and fractionation projects and delivered record operational and financial performance,” stated Frank Semple, Chairman, President and Chief Executive Officer of MarkWest. “Given the recent decline in commodity prices we are working with our producer customers to optimize our midstream operations to support their revised capital plans. The majority of our capital expenditures are in the Marcellus where we are currently processing approximately 90 percent of all rich-gas production. These Northeast Shales continue to provide the best drilling economics in the U.S. and our producer customers continue to deliver strong execution and volume growth. We look forward to another year of operational excellence, best-of-class customer service and solid distribution growth for our unitholders.”

BUSINESS HIGHLIGHTS

The Panola Pipeline, which transports NGLs, originates in Carthage, Texas and extends 181 miles to Mont Belvieu, Texas. Enterprise recently announced plans to install 60 miles of new pipeline, as well as pumps and other associated equipment as part of an expansion project designed to increase capacity by 50,000 Bbl/d. The incremental capacity is expected to be available in the first quarter of 2016.

· Today, the Partnership is announcing the execution of a definitive agreement with Newfield Exploration (NYSE: NFX) (Newfield) to support the development of resources in the Cana-Woodford. Under terms of the agreements, the Partnership will provide gathering and processing services for associated gas from Newfield’s STACK acreage, from the Woodford and Meramec Shales located in Kingfisher, Blaine and Canadian counties, Oklahoma.

Distributable Cash Flow Sensitivity Analysis

(unaudited, in millions)

The Partnership periodically estimates the effect on DCF resulting from changes in its volume forecast and NGL prices. The Partnership has become less sensitive to changes in commodity prices as a result of significant increases in fee-based income. For the full-year 2015, the Partnership estimates that net operating margin will be approximately 89 percent fee-based.

The analysis further assumes derivative instruments outstanding as of February 20, 2015, and production volumes estimated through December 31, 2015.

Estimated Range of 2015 DCF

			Volume Forecast (1)
			Low Case		Base Case		High Case
NGL $/Gallon (2)(3)	$	0.70	$	751	$	780	$	800
	$	0.65	$	740	$	769	$	789
	$	0.60	$	729	$	758	$	778
	$	0.55	$	719	$	747	$	766
	$	0.50	$	708	$	736	$	755
	$	0.45	$	696	$	724	$	743

(1) Volume Forecast is increased/decreased by 5% in the Marcellus and Utica segments for the High and Low Cases.

(2) The composition is based on the Partnership’s projected NGL barrel of approximately: Ethane: 35%, Propane: 35%, Iso-Butane: 6%, Normal Butane: 12%, Natural Gasoline: 12%.

(3) Composite NGL prices are based on the Partnership’s average forecasted price.

The table is based on current information, expectations, and beliefs concerning future developments and their potential effects, and does not consider actions the Partnership’s management may take to mitigate exposure to changes. Further, the table does not consider the effects that such hypothetical adverse changes may have on overall economic activity. Historical volumes, prices and correlations do not guarantee future results.

Although the Partnership believes the expectations reflected in this analysis are reasonable, the Partnership can give no assurance that such expectations will prove to be correct and readers are cautioned that projected performance, results, or distributions may not be achieved. Actual changes in market prices, market conditions and constraints, production, NGL composition, infrastructure availability, market participants, and ratios between product prices may differ from the assumptions utilized in the analysis. Actual results, performance, distributions, volumes, events, or transactions could vary significantly from those expressed, considered or implied in this analysis. All results, performance, distributions, volumes, events or transactions are subject to a number of uncertainties and risks. Those uncertainties and risks may not be factored into or accounted for in this analysis. Readers are urged to carefully review and consider the cautionary statements and disclosures made in the Partnership’s periodic reports filed with the SEC, specifically those under the heading “Risk Factors.”
