Mid-Con Energy Partners, LP Announces Second Quarter 2017 Operating and Financial Results

TULSA, August 2, 2017 – Mid-Con Energy Partners, LP (NASDAQ: MCEP) ("Mid-Con Energy" or the "Partnership") announces operating and financial results for the second quarter ended June 30, 2017.

"During the second quarter, we were presented with some challenges caused by several unexpected events that impacted production and operating expenses," commented Jeff Olmstead, President and CEO. "Weather in May, particularly in Northeastern Oklahoma, led to greater than normal downtime and increased LOE to repair certain damage caused by severe storms. We also had several primary wells in our Permian core area decline at a faster rate than we anticipated. That said, our team was able to partially offset these production losses with better than expected results from development. For example, we saw positive waterflood response to recent injection at select properties in our Permian and Northeastern Oklahoma core areas. This will allow us to accelerate investment during the third quarter to capitalize on these waterflood responses, and should result in production growth during the second half of this year."

SECOND QUARTER 2017 SUMMARY

The following table reflects selected unaudited operating and financial results for the second quarter of 2017, compared to the first quarter of 2017 and the second quarter of 2016. Mid-Con Energy’s unaudited condensed consolidated financial statements are included at the end of this press release.

⁽¹⁾ Production volumes in Boe equivalents calculated at a Btu conversion rate of six Mcf per Bbl.

⁽²⁾ Net premiums include those incurred previously, or upon settlement, that are attributable to instruments that settled during the period.

⁽³⁾ Non-GAAP financial measure. Please refer to the related disclosure and reconciliation of net (loss) income to Adjusted EBITDA and Distributable Cash Flow included in this press release.

SECOND QUARTER 2017 RESULTS

Production - Production for the second quarter of 2017 was 324 MBoe, or 3,560 Boe/d. On a daily basis, this represented a 1.7% decrease from the first quarter of 2017 and a 12.7% decrease year-over-year. The sequential decrease was primarily related to natural declines at select Permian properties, increasing water cuts in certain Southern Oklahoma waterflood units, and downtime at select Northeastern Oklahoma properties caused by storms in May 2017. These declines were partially offset by better than anticipated new drill results at our Permian core area, as well as, positive responses from key waterflood projects in Northeastern Oklahoma and Permian. Year-over-year, lower production was also impacted by the Hugoton divestiture completed in July 2016.

Price Realizations - Oil and natural gas sales were $13.9 million in the second quarter of 2017, or $43.04/Boe. On a per Boe basis, this represented an 8.6% decrease from the first quarter of 2017 and an 8.1% increase year-over-year. Cash settlements from matured derivatives, inclusive of net premiums, were negative $1.0 million in the second quarter of 2017, or ($3.03)/Boe. Cash settlements from matured derivatives, inclusive of net premiums, were ($4.39)/Boe in the first quarter of 2017 and $7.36/Boe in the second quarter of 2016. The resulting realized prices, after incorporating cash settlements from matured derivatives, inclusive of net premiums, were $40.01/Boe in the second quarter of 2017, $42.70/Boe in the first quarter of 2017, and $47.19/Boe in the second quarter of 2016.

Lease Operating Expenses ("LOE") - LOE was $5.6 million in the second quarter of 2017, representing an 11.8% increase from the first quarter of 2017 and a decrease of 3.4% from the second quarter of 2016. The increase in aggregate LOE sequentially reflected storm damage at select Northeastern Oklahoma properties and higher non-routine operational enhancements in Southern Oklahoma and Northeastern Oklahoma. On a per Boe basis, LOE in the second quarter of 2017 of $17.23/Boe increased 12.5% sequentially and 10.7% year-over-year due to lower production.

Production Taxes - Production taxes in the second quarter of 2017 were $0.7 million, or $2.18/Boe, reflecting an effective tax rate of 5.1%. Production taxes in the first quarter of 2017 were $0.8 million, or $2.46/Boe, for an effective tax rate of 5.2%. Production taxes in the second quarter of 2016 were $0.7 million, or $1.97/Boe, reflecting an effective tax rate of 5.0%.

Impairment Expense - We review our long-lived assets to be held and used, including proved oil and natural gas properties, whenever events or circumstances indicate that the carrying value of those assets may not be recoverable. If the carrying amount exceeds the property's estimated fair value, we adjust the carrying amount of the property to fair value through a charge to impairment expense. For the second quarter of 2017, we recorded approximately $17.7 million of non-cash impairment expense primarily associated with one project in our Northeastern Oklahoma core area. The Partnership recognized approximately $4.5 million of non-cash impairment expense during the second quarter of 2016, which included a $0.9 million impairment of proved oil and natural gas properties and $3.6 million impairment related to oil and natural gas properties sold. There was no impairment charge for first quarter of 2017.

Depreciation, Depletion and Amortization Expenses ("DD&A") - DD&A for the second quarter of 2017 was $4.6 million, or $14.29/Boe. On a per Boe basis, DD&A decreased 4.4% from the first quarter of 2017 and 8.6% from the second quarter of 2016. The sequential and year-over-year decrease in DD&A per Boe was largely due to lower depletion rates, partially offset by the net impact of the acquisitions and divestitures.

General and Administrative Expenses ("G&A") - G&A in the second quarter of 2017 was $1.5 million, or $4.54/Boe, and included $0.1 million, or $0.53/Boe, in non-cash equity-based compensation expense related to the Partnership’s Long-Term Incentive Program, and $0.1 million in acquisition related expenses. G&A for the first quarter of 2017 was $1.8 million, or $5.60/Boe, and included $0.2 million in non-cash equity-based compensation expense. G&A for the second quarter of 2016 was $1.5 million, or $3.98/Boe, and included $0.3 million in non-cash equity-based compensation expense. The sequential decrease in aggregate G&A was due to lower professional and public reporting expenses related to year-end financial statements audit and Schedule K-1 tax preparation that historically occur during the first quarter.

2

Net Interest Expense - Net interest expense for the second quarter of 2017 was $1.5 million, a 6.1% increase from the first quarter of 2017 and a 25.1% decrease from the second quarter of 2016. The effective interest rate for the period was 3.8%, compared to 3.6% in the first quarter of 2017 and 4.1% in the second quarter of 2016. The year-over-year variance was due to reduced borrowings outstanding under the revolving credit facility and a lower effective interest rate based on borrowing utilization.

Net (Loss) Income- For the second quarter of 2017, Mid-Con Energy reported net loss of $15.2 million. Net loss per limited partner unit was $0.52 (basic and diluted) based on the weighted average limited partner units outstanding during the period of 29.9 million (basic and diluted). Net income for the first quarter of 2017 was $4.4 million, or $0.12 (basic) and $0.11 (diluted) per limited partner unit, based on a weighted average of 29.9 million (basic) and 41.8 million (diluted) limited partner units outstanding during the period. Net loss for the second quarter of 2016 was $15.8 million, or $0.52 per limited partner unit (basic and diluted), based on a weighted average of 29.8 million limited partner units outstanding during the period. The negative sequential variance was primarily attributable to a non-cash impairment expense, lower realized pricing, and higher LOE. The positive variance year-over-year was attributable to higher benchmark pricing, lower LOE, and a gain on unsettled derivatives.

Adjusted EBITDA - Adjusted EBITDA, a Non-GAAP measure, for the second quarter of 2017 was $5.5 million, or $16.90/Boe. Adjusted EBITDA was $19.84/Boe in the first quarter of 2017 and $31.35/Boe in the second quarter of 2016. The sequential decrease in Adjusted EBITDA, in aggregate and per Boe, was primarily due to lower production, lower realized pricing, and higher LOE. Year-over-year, the decrease in Adjusted EBITDA was due to lower cash settlements for matured derivatives, inclusive of net premiums, and lower production.

Distributable Cash Flow ("DCF") - DCF, a Non-GAAP measure, was $2.9 million for the second quarter of 2017 after subtracting $1.2 million in cash interest expense, $0.8 million in estimated maintenance capital expenditures, $0.1 million in other income, and $0.5 million in distributions to preferred unitholders from Adjusted EBITDA.

WHEATLAND ACQUISITION

In June 2017, Mid-Con Energy closed on the acquisition of multiple operated oil and natural gas properties with an average working interest of approximately 69% located in Oklahoma County and Cleveland County, Oklahoma for cash consideration of approximately $4.2 million, subject to customary post-closing adjustments. At June 30, 2017 benchmark pricing, management estimated net total proved reserves related to the acquisition of 1.0 million barrels of oil equivalent, of which approximately 72% were categorized as proved developed producing. The properties include current average daily production of approximately 125 net Boe/d (85% oil) and are comprised of 39 active producing wells, 22 injection wells, and one water supply well. The acquisition was funded with available cash and borrowings under the revolving credit facility.

LIQUIDITY AND BORROWING BASE SUMMARY

In May 2017, Mid-Con Energy’s lender group reaffirmed the Partnership’s $140.0 million borrowing base as part of the regularly scheduled spring semi-annual redetermination. There were no changes to the terms or conditions of the credit agreement. The next semi-annual borrowing base redetermination is expected to occur on or around October 31, 2017.

At June 30, 2017, Mid-Con Energy had total liquidity of $19.5 million, which consisted of $0.5 million of cash and $19.0 million of available borrowings under its revolving credit facility that had a conforming borrowing base of $140.0 million at quarter end.

HEDGING SUMMARY

Mid-Con Energy enters into various commodity derivative contracts intended to achieve more predictable cash flows by reducing the Partnership's exposure to short-term fluctuations in the price of oil and natural gas. We believe this risk management strategy will serve to secure a portion of our revenues and, by retaining some opportunity to participate in upward price movements, may also enable us to realize higher revenues during periods when prices rise.
