RRMS Rose Rock Midstream, L.P. Common Units Representing Limited Partner Interests

SemGroup® Corporation (NYSE:SEMG) today announced its financial results for the three months ended March 31, 2016.

SemGroup reported revenues for the first quarter 2016 of $314.9 million with net loss attributable to SemGroup of $15.3 million, or $0.35 per diluted share, compared to revenues of $382.5 million with a net income attributable to SemGroup of $0.7 million, or $0.02 per diluted share, for the fourth quarter 2015. For the first quarter 2015, revenues totaled $298.3 million with net income attributable to SemGroup of $1.5 million, or $0.03 per diluted share. Included in the first quarter 2016 net loss of $15.3 million is $52.9 million of non-cash impairment charges related to the company’s SemGas business and its non-controlling investment in NGL Energy Partners LP (NGL Energy).

SemGroup's adjusted earnings before interest, taxes, depreciation and amortization (Adjusted EBITDA) was $77.7 million for the first quarter 2016, an increase of approximately 11% year-over-year as compared to first quarter 2015 results of $70.0 million, a decrease of  2% as compared to fourth quarter 2015 results of  $79.3 million. Adjusted EBITDA, which is a non-GAAP measure, is reconciled to net income below.

"We are off to a solid start for 2016, remaining consistent with the prior quarter and meeting expectations," said Carlin Conner, president and chief executive officer of SemGroup. "Maintaining our conservative price outlook, and considering the sale of all of our limited partnership units of NGL Energy and their associated distributions, we expect to be below the midpoint of our 2016 consolidated Adjusted EBITDA guidance. We ended the first quarter of 2016 with ample liquidity, a strong balance sheet and credit metrics that are favorable to our targeted levels."

First Quarter 2016 DividendThe SemGroup board of directors declared a quarterly cash dividend to common shareholders of $0.45 per share, resulting in an annualized dividend of $1.80 per share. This represents an increase of approximately 18% over the dividend of $0.38 per share with respect to the first quarter of 2015. The dividend will be paid on May 26, 2016 to all common shareholders of record on May 16, 2016.

Recent DevelopmentOn April 27, 2016, the company sold all of its NGL Energy limited partner units for $60.5 million. We plan to use the proceeds from the sale to pay down debt. The company maintains its 11.78% interest in NGL Energy's general partner.

2016 GuidanceSemGroup reaffirms 2016 consolidated Adjusted EBITDA guidance of between $270 and $320 million. Due primarily to the company's recent sale of NGL Energy limited partner units, the company expects to come in below the midpoint of its guidance range. The company is on track to deploy approximately $455 million in capital investments in 2016. The company expects to maintain its current dividend of $0.45 per share and dividend coverage of approximately 1.2 times throughout 2016. Cash Available for Dividends, which is a non-GAAP measure, is reconciled to its most directly comparable GAAP measure below.

Non-GAAP Financial MeasuresSemGroup’s non-GAAP measures, Adjusted EBITDA and cash available for dividends, are not GAAP measures and are not intended to be used in lieu of GAAP presentation of net income (loss), which is the most closely associated GAAP measure. Adjusted EBITDA represents earnings before interest, taxes, depreciation and amortization, adjusted for selected items that SemGroup believes impact the comparability of financial results between reporting periods. Although SemGroup presents selected items that it considers in evaluating its performance, you should also be aware that the items presented do not represent all items that affect comparability between the periods presented. Variations in SemGroup’s operating results are also caused by changes in volumes, prices, exchange rates, mechanical interruptions and numerous other factors. These types of variances are not separately identified in this presentation. Cash available for dividends is based on Adjusted EBITDA, as described above, adjusted to exclude the earnings of our subsidiary, Rose Rock Midstream, cash income taxes, cash interest expense and maintenance capital expenditures and include cash distributions received from Rose Rock Midstream.

These measures may be used periodically by management when discussing our financial results with investors and analysts and are presented as management believes they provide additional information and metrics relative to the performance of our businesses.  These non-GAAP financial measures have important limitations as analytical tools because they exclude some, but not all, items that affect the most directly comparable GAAP financial measures. You should not consider non-GAAP measures in isolation or as substitutes for analysis of our results as reported under GAAP. Management compensates for the limitations of our non-GAAP measures as analytical tools by reviewing the comparable GAAP measures, understanding the differences between the non-GAAP measure and the most comparable GAAP measure and incorporating this knowledge into its decision-making processes. We believe that investors benefit from having access to the same financial measures that our management uses in evaluating our operating results. Because all companies do not use identical calculations, our presentations of non-GAAP measures may be different from similarly titled measures of other companies, thereby diminishing their utility.
