Penn Virginia Corporation Reports Fourth Quarter and Year-End 2016 Results and Provides

Operational Update with 2017 and Preliminary 2018 Guidance

HOUSTON, TX — (Marketwired) — 03/15/17 — Penn Virginia Corporation (“Penn Virginia” or the “Company”) (NASDAQ: PVAC) today announced its financial and operational results for the three months and year ended December 31, 2016.

Key Financial Highlights

Management Comment

John A. Brooks, Interim Principal Executive Officer and Chief Operating Officer, commented, “This is an exciting time for Penn Virginia. We restarted the Eagle Ford drilling program in November 2016 by drilling the third well on the three-well Sable pad and have since drilled seven additional wells with six wells completed. The Sable wells were turned to sales in February 2017 and have been producing for 38 days, with 24-hour IP rates for the pad reaching 6,540 BOEPD (6,156 BOPD, 94% oil), or 500 BOEPD per 1,000 feet of flowing lateral. The 30-day IP rate for the Sable pad was 2,776 BOEPD (2,614 BOPD, 94% oil), or 204 BOEPD per 1,000 feet of flowing lateral. We recently completed the three-well Axis pad at the northern extent of our acreage, which generated a combined 24-hour IP rate of 6,341 BOEPD (5,908 BOPD, 93% oil), or 299 BOEPD per 1,000 feet of flowing lateral. We also recently finished drilling the four-well Kudu pad and are preparing to commence completion operations. Our first rig has moved to the Zebra pad to drill the first of three wells. Our second rig recently spudded the Lager 3H which is our first Area 2 test using slickwater completions.”

“Assuming an average 400 feet between laterals, we have identified approximately 525 gross lower Eagle Ford drilling locations across our approximately 54,000 net acres of core oil-rich acreage in Gonzales and Lavaca Counties. This equates to approximately ten years of drilling inventory at our current two-rig drilling pace. Of these 525 locations, there are approximately 360 in Area 1 and 165 in Area 2. We believe most of the Area 1 locations have a break-even oil price (10% IRR) of $35/barrel at current well costs. We expect similar economics in Area 2 but we will need to confirm this with test results. In addition to these identified opportunities, we hope to further increase our inventory with additional down spacing, as well as future derisking of other zones, including the upper Eagle Ford and the Austin Chalk formation.”

Mr. Brooks continued, “Our team is committed to continuously improving our well results. We have already seen an approximate 30% increase in our well productivity using our Gen 3 slickwater completion design over the former cross-link hybrid type curve. This was realized over the past 18 wells completed in late 2015 and early 2016. We are currently testing our Gen 4 slickwater completion design in Area 1 and Area 2. The Gen 4 design targets pumping 2,500 pounds of proppant per foot of lateral on nominal 200-foot stage spacing. The actual spacing can vary from 170 feet to 220 feet depending on the rock properties. We intentionally group rock with similar properties into the same frac stage. This results in more uniform treating rates and pressures, leading to smoother stimulation profiles and hopefully, increased productivity.”

Mr. Brooks concluded, “Given our strong liquidity, proven oil asset base and recent operating successes, we are evaluating all strategic alternatives available to the Company to maximize shareholder value.”

Operational Results and Operating Update

Total production in the fourth quarter of 2016 was 857 MMBOE or 9,316 BOEPD, with 68% of production comprised of crude oil, 16% of natural gas liquids (NGLs), and 16% of natural gas.

Fourth quarter production from the Company’s Eagle Ford operations was 773 MBOE, or 8,402 BOEPD, and accounted for 90% of total Company production. Approximately 74% of fourth quarter Eagle Ford production was from crude oil, 14% was from NGLs, and 12% was from natural gas.

The three-well Sable pad was turned to sales in February 2017 with a combined 24-hour IP of 6,540 BOEPD for an average of 500 BOEPD per 1,000 feet of flowing lateral. The 30-day gross IP for the three-well pad was 2,776 BOEPD comprised of approximately 94% crude oil. Currently, the Sable 6H well has only eight of 23 completed stages flowing to sales due to an obstruction. The Company will attempt to drill out the remaining fourteen plugs when pressure declines in the wellbore.

The three-well Axis pad was turned to sales at the beginning of March 2017. The wells had a cumulative 24-hour gross IP of 6,341 BOE, comprised of approximately 93% crude oil. The average proppant per stage was 492,600 pounds for the Sable wells and 496,100 pounds for the Axis wells. The average spacing between stages was 217 feet for the Sable pad and 200 feet for the Axis pad.

The table below shows the production results and related operating information with respect to the Company’s 2-string lower Eagle Ford wells:

Penn Virginia switched to slickwater completions in the third quarter of 2015. Since that time, the Company has completed 24 gross wells in the lower Eagle Ford, the latest being the three-well Sable pad and the three-well Axis pad. As a group, these 24 gross wells had an average 24-hour IP of 391 BOEPD (360 BOPD, 92% oil) per thousand feet of flowing lateral. The average 30-day IP for the group, not including the three Axis wells which have not yet been producing for 30 days to establish this metric, is 195 BOEPD (179 BOPD, 92% oil) per thousand feet of flowing lateral. This is a 31% increase in productivity over the former cross-link hybrid completion design.

Fourth Quarter 2016 Financial Results

Total product revenues for the fourth quarter of 2016 were $32.3 million. Total direct operating expenses, defined as general and administrative expense (G&A) excluding share-based compensation, lease operating expense (LOE), gathering, processing and transportation expense (GPT) and severance and ad valorem taxes, for the fourth quarter were $12.7 million. Operating income for the fourth quarter of 2016 was $10.3 million. The Company reported a net loss of $1.9 million for the fourth quarter of 2016. Adjusted EBITDAX (a non-GAAP measure reconciled in the Appendix of this release) for the fourth quarter of 2016 was $21.1 million.

Full-Year 2016 Financial Results

Following emergence from bankruptcy on September 12, 2016, Penn Virginia adopted fresh start accounting and the full cost method of accounting for oil and gas properties which resulted in the Company becoming a new entity for financial reporting purposes. References to “Successor” relate to the financial position and results of operations of the reorganized Penn Virginia from September 13, 2016 to December 31, 2016. References to “Predecessor” relate to the financial position of Penn Virginia before application of fresh start accounting and conversion to the full cost method of accounting for oil and gas properties prior to and including September 12, 2016. As a result of the application of fresh-start accounting, the conversion to the full cost method of accounting for oil and gas properties, and the effects of the implementation of the Company’s plan of reorganization, financial results for the Successor from and after September 13, 2016 are not comparable to financial results of the Predecessor prior to that date.

Total production for full-year 2016 was 4,386 MBOE, or 11,983 BOEPD, with 69% comprised of oil. Total product revenues for full-year 2016 were $132.3 million. The Company reported an operating loss of $9.5 million for full-year 2016. Full-year 2016 net income was $1,049.3 million and includes $1,145.0 million of net reorganization items related to the bankruptcy. Adjusted EBITDAX (a non-GAAP measure reconciled in the Appendix of this release) was $117.7 million for full-year 2016.

Year-End 2016 Proved Reserves

Penn Virginia’s total proved reserves as of December 31, 2016 increased 13% to 49.5 MMBOE compared to 43.7 MMBOE reported at year-end 2015. The composition of the reserves at the end of 2016 were 74% oil, 14% NGL and 12% natural gas, with 53% of the reserves classified as proved developed. Year-end 2015 reserves were 68% oil, 16% NGL and 16% natural gas, and 75% proved developed. Proved reserves in the Eagle Ford increased 17% to 47.0 MMBOE at year-end 2016 compared to 40.1 MMBOE at year-end 2015.

Penn Virginia’s independent reserve engineering firm, DeGolyer and MacNaughton, Inc., completed its estimate of the Company’s year-end 2016 proved reserves in accordance with Securities and Exchange Commission (SEC) guidelines using pricing of $42.75 per barrel for crude oil and $2.48 per million British Thermal Units (MMBtu) for natural gas. Year-end 2015 SEC oil and gas pricing was $50.28 per barrel and $2.59 per MMBtu, 15% and 4% higher than the 2016 pricing, respectively.

The Company’s standardized measure of discounted future net cash flows relating to proved oil and gas reserves (Standardized Measure) was $317.6 million as of December 31, 2016, compared to $323.3 million as of year-end 2015. The decrease in the Standardized Measure of the Company’s proved reserves is primarily a result of the decrease in the average NYMEX oil and gas price offset by an increase in proved reserves. The value of the Company’s total proved reserves, utilizing the SEC price guidelines, discounted at ten percent and before tax (PV-10, a non-GAAP measure reconciled to Standardized Measure in the Appendix of this release) was $317.6 million as of December 31, 2016 (no adjustment from Standardized Measure). The PV-10 value of the Company’s total proved developed producing (PDP) reserves utilizing the SEC price guidelines was $246.2 million as of December 31, 2016. Using strip pricing at December 31, 2016 (disclosed in the Appendix of this release), the PV-10 value of the Company’s total proved reserves and PDP reserves was $577.7 million and $371.5 million, respectively.

2017 and Preliminary 2018 Guidance

The table below sets forth the Company’s capital plan and operational guidance for 2017, and provides a preliminary capital plan and production guidance for 2018.

Production in the first quarter of 2017 is expected to be 8,800 to 9,200 BOEPD. Average daily production in the fourth quarter of 2017, or the exit rate, is anticipated to be between 11,200 to 12,100 BOEPD (20% to 30% growth over fourth quarter of 2016). The Company anticipates total 2017 production volumes at 3.7 to 4.0 MMBOE, or 10,000 to 11,000 BOEPD, with approximately 74% of production comprised of oil.

Realized price differentials, which include deductions from posted market prices generally for quality and basis differences, are expected to be $2.00 to $2.50 per barrel lower than NYMEX WTI pricing and $0.10 to $0.20 per MMBtu lower than NYMEX Henry Hub natural gas pricing.

Lease operating expense is expected to average $5.00 to $5.50 per BOE for the full year 2017, with higher per barrel costs anticipated early in the year, declining over time with increased production. Cash G&A expense (excluding share-based compensation) for the year is expected to be $13 to $16 million. Share based G&A expense is expected to be $4 to $5 million for the full year 2017. Gathering, Processing and Transportation expense guidance for the full year 2017 is expected to average $2.75 to $3.15 per BOE. Ad valorem and severance tax is expected to be approximately 7% of production revenues.

Capital expenditures for 2017 are expected to total between $120 and $140 million with approximately 90% of capital being directed to drilling and completions capital on the Company’s Eagle Ford assets. The capital plan provides for drilling 41 to 44 gross wells (19 to 22 net wells) with 31 to 34 gross wells (16 to 19 net wells) turned to sales. The Company plans to fund its 2017 capital expenditure plan with cash flow from operations and borrowings under its credit facility. The Company has ample liquidity to accelerate operations if desired.

The Company expects well costs to range between $4.9 and $5.1 million per well for wells with two strings of casing (Area 1), assuming Gen 3 slickwater completion design with 24 frac stages spaced 250 feet apart with 2,000 pounds of proppant per foot on 6,000 feet of treatable lateral. Wells are anticipated to generate approximately 70% internal rates of return (IRR) before tax at $55.00 per barrel of oil and $3.00 per MMBtu of natural gas.

The Company will test its Gen 4 slickwater completion design in the first half of 2017 on 18 gross wells. The Company’s Gen 4 wells are anticipated to cost $5.5 to $5.7 million for a typical well with 6,000 feet of treatable lateral, an increase of $0.6 million over the Gen 3 wells as a result of the six additional frac stages and increased proppant with the new design. The higher cost per well is expected to be more than offset by increased production and ultimate recoveries but the expected uplift has not been factored into current production guidance or IRR calculations.

The Company’s preliminary estimate for its 2018 capital program, based on a two-rig Eagle Ford development program and Gen 3 completion design, is $125 to $145 million with 90% of capital being directed to Eagle Ford drilling and completions. If the Company’s 2017 tests of Gen 4 completion design and/or Area 2 are successful, these estimates may be revised materially. The Company expects to fund the program primarily with cash flow from operations. Production for full year 2018 is expected to be approximately 4.6 to 5.0 MMBOE, or 12,600 to 13,700 BOEPD, an increase of approximately 20% to 30% over the mid-point of 2017 guidance. The exit rate for 2018 is expected to be 13,500 to 14,500 BOEPD.

These estimates are meant to provide guidance only and are subject to material revision.

Capital Resources and Liquidity

As of December 31, 2016, Penn Virginia’s $200 million credit facility, with an initial borrowing base of $128 million, had a balance of $25.0 million, and the Company had liquidity at the end of 2016 of $109.0 million, including $6.8 million in cash and $0.8 million in outstanding letters of credit. Current liquidity as of March 10, 2017 was $103.6 million with $30 million outstanding on the credit facility, $6.4 million in cash, and $0.8 million in outstanding letters of credit.

Derivatives Update

Adjusted EBITDAX represents net income (loss) before income tax benefit, interest expense, depreciation, depletion and amortization expense, exploration expense and share-based compensation expense, further adjusted to exclude the effects of non-cash changes in the fair value of derivatives, restructuring expenses, impairments, net gains and losses on the sale of assets, loss on extinguishment of debt and other non-cash items. We believe this presentation is commonly used by investors and professional research analysts in the valuation, comparison, rating and investment recommendations of companies within the oil and gas exploration and production industry. We use this information for comparative purposes within our industry. Adjusted EBITDAX is not a measure of financial performance under GAAP and should not be considered as a measure of liquidity or as an alternative to net income (loss). Adjusted EBITDAX as defined by Penn Virginia may not be comparable to similarly titled measures used by other companies and should be considered in conjunction with net income (loss) and other performance measures prepared in accordance with GAAP, such as operating income or cash flows from operating activities. Adjusted EBITDAX should not be considered in isolation or as a substitute for an analysis of Penn Virginia’s results as reported under GAAP.

CERTAIN NON-GAAP FINANCIAL MEASURES - unaudited

(in thousands)

Non-GAAP PV-10 value is the estimated future net cash flows from estimated proved reserves discounted at an annual rate of 10 percent before giving effect to income taxes. The standardized measure of discounted future net cash flows is the after-tax estimated future cash flows from estimated proved reserves discounted at an annual rate of 10 percent, determined in accordance with generally accepted accounting principles (GAAP). We use non-GAAP PV-10 value as one measure of the value of our estimated proved reserves and to compare relative values of proved reserves among exploration and production companies without regard to income taxes. We believe that securities analysts and rating agencies use PV-10 value in similar ways. Our management believes PV-10 value is a useful measure for comparison of proved reserve values among companies because, unlike standardized measure, it excludes future income taxes that often depend principally on the characteristics of the owner of the reserves rather than on the nature, location and quality of the reserves themselves.

NYMEX PRICING USED IN THE CALCULATION OF PV-10 AT STRIP

The Company used the posted monthly closing prices through December 2029 for NYMEX WTI oil and through December 2022 for NYMEX Henry Hub natural gas for the analysis. The first five years of calendar average prices are shown.
