Mid-Con Energy Partners, LP Announces Second Quarter 2013 Results

DALLAS, August 6, 2013 – Mid-Con Energy Partners, LP (NASDAQ: MCEP) (“Mid-Con Energy” or the “Partnership”) announced today its financial and operating results for the second quarter ended June 30, 2013.

Mid-Con Energy highlighted the following achievements for the second quarter of 2013:

The following table reflects selected operating and financial results for the second quarter of 2013, compared to the second quarter of 2012 and first quarter of 2013. Mid-Con Energy’s condensed consolidated financial statements can be found in the supplemental tables of this press release.

Craig George, Executive Chairman of the Board, commented, “We are pleased to report positive second quarter 2013 results which include increases in both production and Adjusted EBITDA. Further, our recently announced distribution increase to $0.515 per unit represents our fourth consecutive quarterly increase in distribution rate, now approximately 8% above our initial quarterly distribution rate of $0.475 per unit. We believe these results reflect our ongoing commitment to our founding purposes: to grow reserves and production, generate stable cash flows, make cash distributions, and, over time, to increase those distributions.”

Second Quarter 2013 Results

Production volumes for the second quarter of 2013 were 236 thousand barrels of oil equivalent (MBoe) or approximately 2,593 Boe per day on average. In comparison, Mid-Con Energy’s production volumes for the second quarter of 2012 were 159 MBoe, or approximately 1,747 Boe per day on average. Production gains, compared to the prior year, contained both organic and acquisition growth components. While production response varies at the property level, Mid-Con Energy’s waterflood portfolio as a whole continues to benefit from increased injection and active infill drilling programs in the Southern Oklahoma core area.

Oil sales, excluding the effect of commodity derivatives, were approximately $20.9 million in the second quarter of 2013 and resulted in an average realized oil price of $90.98 per barrel (Bbl). Oil sales in the second quarter of 2012 were approximately $13.7 million, or $88.71 per Bbl. Approximately 80% of Mid-Con Energy’s oil production during the second quarter of 2013 was hedged at an average price of $98.02 per Bbl. Given the favorable variance between the average hedge price and NYMEX WTI, the Partnership received $0.7 million for realized commodity derivatives during the second quarter of 2013, or $3.08 per Bbl. In comparison, Mid-Con Energy received $0.9 million for realized commodity derivatives during the second quarter of 2012, or $5.86 per Bbl.

Lease operating expenses were $3.7 million, or $15.87 per Boe, in the second quarter of 2013, compared to $2.8 million, or $17.47 per Boe, in the second quarter of 2012. Mid-Con Energy’s total well count and aggregate lease operating expenses were higher during the second quarter of 2013 largely due to increased drilling activity and incremental operating costs from interests acquired since the second quarter of 2012. However, increased production received from these wells outpaced the added expenses, resulting in a lower lease operating expense per Boe.

Production taxes in the second quarter of 2013 were $0.9 million, or $3.70 per Boe, for an effective tax rate of approximately 4.1%. Production taxes in the second quarter of 2012 were $42 thousand, or $0.26 per Boe, for an effective tax rate of approximately 0.3%. Mid-Con Energy received a $0.5 million production tax credit during the second quarter of 2012 related to the state’s Enhanced Recovery Project Gross Production Tax Exemption.

Total general and administrative expenses during the second quarter of 2013 were $1.3 million and included $0.1 million in non-cash equity-based compensation expense related to the Partnership’s long-term incentive program. Total general and administrative expenses during the second quarter of 2012 were $1.2 million and included $38 thousand in non-cash equity based compensation expense.

Adjusted EBITDA for the second quarter of 2013 was $16.1 million, approximately 50% above Adjusted EBITDA for the second quarter of 2012 of $10.7 million. Distributable Cash Flow for the second quarter of 2013 was $12.8 million after subtracting $0.8 million in cash interest expense and $2.5 million in estimated maintenance capital expenditures.

Mid-Con Energy reported net income of $10.5 million, or $0.54 per limited partner unit, for the second quarter of 2013. This included $1.0 million of unrealized gains from commodity derivatives and $1.6 million non-cash impairment charge related to a reduction in carrying value of certain miscellaneous properties. Net income during the second quarter of 2012 was $22.4 million, or $1.24 per limited partner unit, and included $14.5 million of unrealized gains from commodity derivatives.

Increased Cash Distribution

As announced on July 25, 2013, the Board of Directors of Mid-Con Energy’s general partner declared its fourth consecutive increase in the quarterly cash distribution rate to $0.515 per unit for the quarter ended June 30, 2013, or $2.06 per unit on an annualized basis. This represented an approximate 8% increase over the second quarter 2012 cash distribution rate of $0.475 per unit and an approximate 2% sequential increase over the first quarter 2013 cash distribution rate of $0.505 per unit. The cash distribution will be paid August 14, 2013 to unitholders of record at the close of business on August 7, 2013.

Hedging Update

Mid-Con Energy enters into various commodity derivative contracts intended to achieve more predictable cash flows and to reduce its exposure to fluctuations in the price of oil. The Partnership’s hedging program objective is to protect its ability to make current distributions, and to be better positioned to increase its quarterly distribution over time, while retaining some ability to participate in upward movements in oil prices. Mid-Con Energy uses a phased approach, looking approximately 36 months forward while targeting a higher hedged percentage in the near 12 months of the period.

Supplementing its primary hedging strategy described above, Mid-Con Energy also intends to enter into additional commodity derivative contracts in connection with material increases in its estimated production and at times when management believes market conditions or other circumstances suggest that it is prudent to do so, as opposed to entering into commodity derivative contacts at predetermined times or on prescribed terms.

As of August 6, 2013, the following table reflects volumes of Mid-Con Energy’s production covered by commodity derivative contracts, and the average prices at which the production will be hedged:

Liquidity Update

As of June 30, 2013, the Partnership’s total liquidity of $19.8 million included $0.8 million in cash and cash equivalents and $19.0 million of available borrowings under the revolving credit facility.

In April 2013, Mid-Con Energy’s bank group unanimously reaffirmed the Partnership’s $130.0 million borrowing base as part of its regularly scheduled semi-annual redetermination. There were no changes to the interest rate, repayment terms or number of banks in the revolving credit facility. The next scheduled redetermination of the borrowing base will occur on or about October 30, 2013.
