Roan Resources, Inc. Reports Second Quarter 2019 Results

OKLAHOMA CITY, August 7, 2019 – Roan Resources, Inc. (NYSE: ROAN) (“Roan” or the “Company”) today announced second quarter 2019 operating and financial results.

Second Quarter 2019 Highlights

“We are pleased with the progress the Company has made this quarter,” said Joseph A. Mills, Roan’s Executive Chairman of the Board. “Our focus has been on driving down our overall cost structure and delivering on our production expectations. We were able to beat production on a significantly lower capital spend. The recently completed optimized wells are performing in-line with expectations and are costing less than original forecasts. Finally, our strategic initiative process remains a key focus for the Company and expect to announce the results as soon as possible.”

The Company drilled 17 gross (12.7 net) operated wells (30.5 gross lateral miles) during the second quarter. The Company also brought online 22 gross (15.3 net) operated wells during the quarter, which is three ahead of schedule due to an improvement in cycle times. The average 30-day rate for the 22 gross operated wells brought online during the quarter was 1,165 MBoe/d (42% oil, 23% NGLs, 35% gas), when normalized to a 10,000-foot lateral, with an actual average lateral length of 8,900 feet.

Highlight wells from the second quarter include the Mad Play unit, the Mayes Earl wells, the Mayes Victory Slide wells, the Zenyatta unit and the Red Bullet/Silver Charm unit.

The Zenyatta unit is a 2-well Woodford unit located in Stephens County with approximately 1,000 feet of horizontal separation between wellbores and tested two different Woodford zones, located in the southern SCOOP.

The Red Bullet/Silver Charm unit was completed at the end of the second quarter and is a 4-well unit, with two Mayes wells and two Woodford wells, with 800 to 1,160 feet of horizontal separation and approximately 200 feet of vertical separation between wellbores located in the western Merge. The average per well 30-day IP rates is as follows:

Drill times continue to improve, and the Company drilled its fastest 2-mile well to date during the quarter. The Fusaichi Pegasus 9-4-13-6 3MXH well was drilled in 6.4 days, nearly 60% faster than the average drill time for 2-mile Mayes wells. As a result of faster drill times, drill costs continue to decrease. The Company drilled its wells for an average cost per foot of $140, approximately 25% lower than the previous quarter.

Completion costs per foot also improved by approximately 20% compared to the first quarter of 2019 as a result of lower service costs, more efficient frac designs and more efficient drillouts.

In July, it was announced that Roan had entered into a definitive crude oil gathering agreement with Blue Mountain Midstream LLC. This agreement is for 10 years covering 89,000 net acres in the Merge. Earlier this year, the Company also entered into a definitive agreement with Glass Mountain Pipeline and Navigator SMS Pipeline LLC to blend and ship barrels to Cushing, OK on pipelines for the same dedicated acres. The gathering agreement with Blue Mountain is expected to decrease crude transportation costs by approximately 50% on gathered barrels, as well as decrease volatility in the cost structure for crude transportation. The pipelines should be operational before the end of the year.

Financial Update

Second quarter 2019 net income was $27.2 million, or $0.18 per dilutive share, and adjusted net income (non-GAAP) was $16.9 million, or $0.11 per dilutive share. Second quarter 2019 Adjusted EBITDAX (non-GAAP) was $79.3 million.

See the definitions and reconciliations of adjusted net income, adjusted net income per share, Adjusted EBITDAX, net debt and cash general and administrative (G&A) expense presented within this release to the most directly comparable U.S. generally accepted accounting principles (GAAP) financial measures provided in the supporting tables or definitions at the conclusion of this press release.

Second quarter 2019 average realized prices were $57.76 per barrel of oil (Bo), $11.08 per barrel of NGLs and $1.04 per Mcf of natural gas, resulting in a total equivalent unhedged price of $20.99 per Boe or a total equivalent hedged price of $22.59 per Boe, down 4% quarter over quarter due primarily to further weakness in the NGL and natural gas markets.

The Company’s adjusted cash operating costs (non-GAAP) for the second quarter were $5.44 per Boe, including production expense of $2.44 per Boe, production tax of $1.09 per Boe and cash G&A expense (non-GAAP) of $1.91 per Boe. Both production expense and cash G&A expense were down quarter-over-quarter on a total dollar and per Boe basis. Production expenses benefited from the water disposal agreement with Blue Mountain Midstream LLC, which started early in the second quarter.

Capital expenditures for second quarter 2019 totaled approximately $114.3 million, a $58.5 million reduction as compared to the first quarter 2019 and below adjusted guidance by approximately $26 million. However, approximately $20 million of capital expenditures that were forecasted to be included in second quarter are expected to be recorded in subsequent quarters due to timing and working interest adjustments. The additional reduction to capital expenditures is primarily due to lower completed well costs.

As of the end of the second quarter, Roan had $5.4 million of cash on the balance sheet, $659.6 million drawn on its revolving credit facility and $50.0 million funded on its term loan, resulting in net funded debt of $704.2 million.

During the quarter, the Company enhanced its liquidity position by approximately $100 million through the closing of a term loan facility funded by affiliates of certain significant shareholders of the Company.

The facility was secured at favorable terms for the Company with an interest rate of the three-month LIBOR rate plus 7.5%. As a result, the Company had approximately $150 million of available liquidity as of June 30, 2019.

For the remainder of the year, the Company is over 95% hedged for oil at an average price of $60.39 per barrel and over 75% hedged for natural gas at an average price of $2.90 per MMbtu. A table of the Company’s derivative contracts as of August 7, 2019 is provided at the conclusion of this press release.

Updated Guidance

For the remainder of the year, the Company is projecting it will be in ethane rejection instead of ethane recovery, which impacts production on a monthly basis by approximately 3.3 MBoe/d. After incorporating adjustments for ethane rejection for the forecasted period and the outperformance of the second quarter, the Company is updating its full-year 2019 production guidance to be between 50.5 MBoe/d and 53.5 MBoe/d.

The Company is also reducing full-year 2019 production expense guidance to $2.80 - $3.10 per Boe, to reflect cost reduction initiatives exhibited in the second quarter.

Additionally, the Company is adjusting cash G&A (non-GAAP) to $2.00 to $2.20 per Boe, as a result of the impact of the adjusted volume forecast on the unit cost calculation.

Capital expenditures have been lower than originally forecasted as a result of lower completed well costs due to shorter cycle times and optimized well designs, and lower working interests in operated wells than originally forecasted. For the full-year 2019, capital expenditures are now expected to be between $495 million to $525 million, down $30 million from the prior top-end of guidance. The Company remains focused on achieving free cash flow by the fourth quarter. A table with updated 2019 guidance can be found at the conclusion of this release.

Cautionary Statements     

This press release includes “forward-looking statements” within the meaning of Section  27A of the Securities Act of 1933, as amended, and Section  21E of the Securities Exchange Act of 1934, as amended . All statements, other than statements of historical fact, are forward-looking statements which contain our current expectations about future results. These forward-looking statements are based on certain assumptions and expectations made by the Company, which reflect management’s experience, estimates and perception of historical trends, current conditions and anticipated future developments. Such statements are subject to a number of assumptions, risks and uncertainties, many of which are beyond the control of the Company, which may cause actual results to differ materially from those implied or anticipated in the forward-looking statements. When considering these forward-looking statements, you should keep in mind the risk factors and other cautionary statements found in the Company’s filings with the Securities and Exchange Commission, including its Annual Report on Form 10-K for the year ended December  31, 2018 and any subsequently filed quarterly reports on Form 10-Q.

We caution you that these forward-looking statements are subject to all of the risks and uncertainties, most of which are difficult to predict and many of which are beyond our control, or incidental to the development, production, gathering and sale of oil, natural gas and NGLs. These risks include, but are not limited to, the expectations of plans, strategies, objectives and growth and anticipated financial and operational performance, the structure and timing of any transaction or strategic alternative and whether any transaction or strategic alternative will be completed, commodity price volatility, inflation, lack of availability of drilling and production equipment and services, environmental risks, drilling and other operating risks, regulatory changes, the uncertainty inherent in estimating reserves and in projecting future rates of production, cash flow and access to capital, the timing of development expenditures and the other risks.

Reserve engineering is a process of estimating underground accumulations of oil, natural gas and NGLs that cannot be measured in an exact way. The accuracy of any reserve estimate depends on the quality of available data, the interpretation of such data and price and cost assumptions made by reserve engineers. In addition, the results of drilling, testing and production activities may justify revisions of estimates that were made previously. If significant, such revisions would change the schedule of any further production and development drilling. Accordingly, reserve estimates may differ significantly from the quantities of oil, natural gas and NGLs that are ultimately recovered.

Should one or more of the risks or uncertainties described occur, or should underlying assumptions prove incorrect, our actual results and plans could differ materially from those expressed in any forward-looking statements.

All forward-looking statements, expressed or implied, included in this release are expressly qualified in their entirety by this cautionary statement. This cautionary statement should also be considered in connection with any subsequent written or oral forward-looking statements that we or persons acting on our behalf may issue.

Except as otherwise required by applicable law, we disclaim any duty to update any forward-looking statements, all of which are expressly qualified by the statements in this section, to reflect events or circumstances after the date of this release.

Non-GAAP Financial Measures

Adjusted Net Income and Adjusted Net Income per Share

Adjusted net income and adjusted net income per share are non-GAAP performance measures. The Company defines adjusted net income and adjusted net income per share as net income (loss) and net income (loss) per share excluding non-cash gains or losses on derivatives, gains on early terminations of derivative contracts, exploration expense, aborted offering costs, severance and other employee matter expense and loss (gain) on the sale of other assets. Management uses adjusted net income and adjusted net income per share as an indicator of the Company’s operational trends and performance relative to other oil and natural gas companies. Adjusted net income and adjusted net income per share should not be considered an alternative to net income (loss), operating income, or any other measure of financial performance presented in accordance with GAAP or as an indicator of our operating performance.

Adjusted EBITDAX

Adjusted EBITDAX is a non-GAAP financial measure. The Company defines Adjusted EBITDAX as net income (loss) adjusted for interest expense, income tax expense (benefit), depreciation, depletion, amortization and accretion, exploration expense, non-cash equity-based compensation expense, aborted offering costs, severance and employee matter expenses, expense for allowance for doubtful accounts, (gain) loss on derivative contracts, and cash (paid) received upon settlement of derivative contracts, excluding amounts on contracts settled prior to contract maturity. Adjusted EBITDAX is not a measure of net income (loss) as determined by GAAP. Our accounting predecessor, Roan LLC, passed through its taxable income to its owners for income tax purposes and thus, the Company did not incur historical income tax expenses.

The Company believes Adjusted EBITDAX is useful because it allows our management to more effectively evaluate the operating performance and compare the results of our operations from period to period without regard to our financing methods or capital structure. The Company adds the items listed above to net income (loss) in arriving at Adjusted EBITDAX because these amounts can vary substantially from company to company within our industry depending upon accounting methods and book values of assets, capital structures and the method by which the assets were acquired. Adjusted EBITDAX should not be considered as an alternative to, or more meaningful than, net income (loss) as determined in accordance with GAAP or as an indicator of our operating performance or liquidity. Certain items excluded from Adjusted EBITDAX are significant components in understanding and assessing a company’s financial performance, such as a company’s cost of capital and tax structure, as well as the historic costs of depreciable assets, none of which are components of Adjusted EBITDAX.

Roan’s computations of Adjusted EBITDAX may not be comparable to other similarly titled measures of other companies or to such measure in our revolving credit facility or any of our other contracts.

The following tables present a reconciliation of Adjusted EBITDAX to net income (loss), our most directly comparable financial measure calculated and presented in accordance with GAAP for each of the periods indicated.

Net Debt

Net Debt is a non-GAAP financial measure equal to long-term debt outstanding on the credit facility and term loan, exclusive of any discounts or fees, less cash on hand.

Cash general and administrative expenses per Boe

Cash G&A expense is a non-GAAP measure, which is defined as total general and administrative expense as determined in accordance with GAAP less equity-based compensation expense, expense for allowance for doubtful accounts, severance and employee matter expense and aborted offering costs. Cash G&A expense should not be considered as an alternative to, or more meaningful than, total general and administrative expense as determined in accordance with GAAP and may not be comparable to other companies’ similarly titled measures.
