Lonestar Announces Fourth Quarter 2018 Financial Results And Provides Operational Update

Fort Worth, Texas, March 7, 2019 (PRNewswire) - Lonestar Resources US Inc. (NASDAQ: LONE) (including its subsidiaries, "Lonestar," "we," "us," "our" or the "Company") today reported financial and operating results for the three months and year ended December 31, 2018.

HIGHLIGHTS

• Lonestar reported an 81% increase in net oil and gas production to 13,152 Boe/d during the three months ended December 31, 2018 ("4Q18"), compared to 7,272 Boe/d for the three months ended December 31, 2017 (ì4Q17î). The Company’s record production volumes exceeded the Company’s guidance of 12,600 - 12,800 Boe/d and were 80% crude oil and NGL’s on an equivalent basis.

• Lonestar reported a net income attributable to its common stockholders of $75.2 million during 4Q18 compared to a net loss of $17.6 million during 4Q17. Excluding, on a tax-adjusted basis, certain items that the Company does not view as either recurring or indicative of its ongoing financial performance, Lonestar’s adjusted net income for 4Q18 was $5.4 million, or $0.22 per basic common share. Most notable among these items include: unrealized hedging gains/losses on financial derivatives and stock-based compensation. Please see Non-GAAP Financial Measures at the end of this release for the definition of Adjusted Net Income (Loss), a reconciliation of net income (loss) before taxes to adjusted net income (loss), and the reasons for its use.

• Lonestar reported a 99% increase in Adjusted EBITDAX for the three months ended December 31, 2018 of $40.7 million compared to $20.5 million for 4Q17, which was in the higher end of our guidance of $39.0 - $41.0 million and set another record for the Company. This improvement was driven by an 81% increase in production and a 10% reduction in unit cash operating expenses. Please see Non-GAAP Financial Measures at the end of this release for the definition of Adjusted EBITDAX, a reconciliation of net loss to Adjusted EBITDAX, and the reasons for its use.

• Lonestar has issued production guidance of 11,200 to 12,000 Boe/d for the first quarter of 2019. As commodity prices fell precipitously in the fourth quarter of 2018, Lonestar suspended drilling operations pending the negotiation of contracts for drilling and completion operations which gave the Company sufficient flexibility to "dial-in" activity levels to react to commodity prices and expected cash flow generation capacity. Consequently, Lonestar anticipates the completion of 3 gross/2.9 net wells late in the first quarter of 2019. The midpoint of guidance represents a 49% increase over 1Q18 results.

• Despite a delayed start in completion activity, Lonestar has reiterated its previously-issued 2019 production guidance of 13,700 to 14,700 Boe/d for 2019, which equates to production growth of 27% over 2018 levels. Based the onstream dates associated with its current program, Lonestar has issued Adjusted EBITDAX guidance for 2019 of $140 to $155 million.

• Given the success Lonestar was able to achieve with a dedicated frac spread in 2018, the Company recently executed an agreement with another leading energy service provider for a dedicated frac spread for 2019. This agreement should drive cost down significantly year over year on a per well basis as well as continue to improve

our ability to turn wells into production in a timely and efficient fashion, delivering more predictable results to our shareholders.

• Lonestar continually evaluates its asset portfolio and constantly seeks to improve its capital structure and returns profile. As part of this process, Lonestar has agreed to sell its Pirate assets in Wilson County for $12.3 million. The sale is anticipated to close prior to the end of March 2019. In February, 2019, average daily sales volumes were 219 Boe/d. The Pirate asset is comprised of 3,400 net undeveloped acres and held 7 Proved Undeveloped locations at December 31, 2018.

Lonestar's Chief Executive Officer, Frank D. Bracken, III, commented, "2018 was another year of tremendous per-share growth for Lonestar, coming from a balanced program of drilling and acquisitions. We generated a 81% increase in production and a 99% increase in Adjusted EBITDAX. We extended our track-record of low-cost reserve growth, registering all-sources finding and development costs of $9.07 per BOE while increasing our Proved reserves by 27%. In 2018, we demonstrated substantial improvements in productivity and returns in our core areas, and the focus of our 2019 and 2020 drilling programs will be in these core areas, and additionally on our recently-acquired Sooner property. We have designed our 24-month plan to focus our drilling on areas where we have demonstrated the highest IRR’s in our portfolio, which are in both the crude oil window (Cyclone/Hawkeye and Karnes County), which are 85% oil / 7% NGL’s / 5% gas, and condensate windows (Horned Frog and Sooner), which are 16% oil / 45% NGLs / 39% gas. This returns-focused program is expected to generate 20+% growth in production and EBITDAX through 2020. Importantly, this program is designed to allow the Lonestar to become cash flow self-sufficient in the second half of 2019 and for the full-year in 2020. As a result, we believe that Lonestar will be one of the few companies among its peers who can generate these levels of growth while doing so with internally generated cash flow"

OPERATIONAL UPDATE

• Lonestar reported net oil and gas production of 13,152 Boe/d during the three months ended December 31, 2018, an increase of 81% compared to 7,272 Boe/d during the three months ended December 31, 2017. 4Q18 production volumes consisted of 7,883 barrels of oil per day (60%), 2,675 barrels of NGLs per day (20%), and 15,561 Mcf of natural gas per day (20%). The Company’s production mix for the three months ended December 31, 2018 was 80% liquid hydrocarbons.

• Lonestar’s Eagle Ford Shale assets delivered excellent wellhead realizations in 4Q18. Lonestar’s realized wellhead crude oil price was $64.86 per barrel, which reflects a positive differential of $6.05 /bbl vs. West Texas Intermediate. Lonestar’s realized NGL price was $22.48 per barrel, which at 38% of WTI, was the highest quarterly percentage realizations for NGLs in 2018. Lonestar’s realized wellhead natural gas price was $3.72 per Mcf, reflecting a $0.08/Mcf discount to Henry Hub.

• Lonestar delivered a 10% reduction per Boe in cash operating costs (outlined below) in 4Q18. Total cash expenses, which includes the cash portions of lease operating, gathering, processing, transportation, production taxes, general and administrative, and interest expenses, for the three months ended December 31, 2018 were $25.1 million, which was 63% higher than cash expenses of $15.4 million in the three months ended December 31, 2017. However, on a unit-of-production basis, cash expenses decreased 10% from $20.70 per Boe in the three months ended December 31, 2018 to $23.01 per Boe in the three months ended December 31, 2017.

• Lease Operating Expenses ("LOE") for the three months ended December 31, 2018 were $7.3 million, which was 50% higher than LOE of $4.9 million in the three months ended December 31, 2017 but was outpaced by an 81% increase in production. On a unit-of-production basis, lease operating expenses decreased 17% to $6.01 per Boe for the three months ended December 31, 2018. For 2019, the Company expects LOE to average between $5.50 and $6.00 per Boe.

• Gathering, Processing & Transportation Expenses ("G, P&T") for the three months ended December 31, 2018 were $1.0 million, which was 113% higher than the G, P&T of $0.5 million in the three months ended December

31, 2017, commensurate with a 161% increase in gas production. On a unit-of-production basis, G, P&T increased 18% to $0.80 per Boe for the three months ended December 31, 2018. For 2019, the Company expects G, P&T expense to average between $1.00 and $1.25 per Boe.

• Production taxes for the three months ended December 31, 2018 were $2.9 million, which was 54% higher than production taxes of $1.9 million in the three months ended December 31, 2017, driven largely by an 84% increase in wellhead oil and gas revenues. On a unit-of-production basis, production taxes decreased 15% to $2.38 per Boe for the three months ended December 31, 2018.

• General & Administrative Expenses, excluding stock-based compensation of $0.6 million in the three months ended December 31, 2017 and ($1.7) million in the three months ended December 31, 2018 ("G&A"), increased from $3.2 million to $4.4 million, respectively. On a unit-of-production basis, G&A per Boe was reduced 25% year over year, from $4.79 per Boe in 2017 to $3.62 per Boe in 2018. For 2019, the Company expects G&A to average between $2.50 and $3.00 per Boe.

• Interest Expense excluding amortization of debt issuance cost, premiums, and discounts increased year over year from $5.3 million in the three months ended December 31, 2017 to $9.5 million in 2018. On a unit-of-production basis, interest per Boe decreased 1% year over year from $7.95 per Boe in 2017 to $7.89 per Boe in 2018. For 2019, the Company expects interest expense to average between $7.25 and $8.00 per Boe.

• In the fourth quarter of 2018, Lonestar expanded its Eagle Ford footprint with the Sooner Acquisition, expanding its operational footprint into DeWitt county. Additionally, the Company placed 4 gross / 3.3 net wells online, which included 2 gross / 1.9 net wells in Dimmit County and 2 / 1.4 net wells in Gonzales County. Lonestar expects to continue to grow production organically during 2019 while continuing to look for additional acquisition opportunities within the Eagle Ford. After negotiating updated contracts with its service providers, Lonestar's Board has approved a capital-flexible budget which ranges from 17 gross / 15.6 net wells, which it estimates will cost $107 million, to 20 gross / 18.6 net wells, which are budgeted to cost $130 million.

EAGLE FORD SHALE TREND- WESTERN REGION

In our Western Region, production for the fourth quarter of 2018 averaged approximately 6,825 Boe per day, a 141% increase over the prior year. In October 2018, the Company completed drilling operations on the Asherton #1HN and Asherton #3HN. Through their first 90 days of production, these wells have produced on average 50,000 barrels of oil and 112,550 Mcf of natural gas, or 75,800 barrels of oil equivalent on a three-stream basis, or an average of 843 Boe/d per well over the first 90 days of production.

During 2019 the Company plans to drill 7 gross / 6.9 net wells in its Western region. In La Salle County, the first three wells, the Burns Ranch #11H, Burns Ranch #12H, and Burns Ranch #13H, began flowback operations and are the only wells being brought onstream during the first quarter of 2019. These wells were drilled to average total measured depths of 15,020, 15,030, and 15,036 feet, respectively. The Burns Ranch #11H, #12H, and #13H wells were fracture-stimulated in engineered completions using diverters with an average proppant concentration of 1,485 pounds per foot over 11 stages, 22 stages, and 22 stages, respectively. Lonestar has a 96% WI and 72% NRI in these wells.

Our second set of wells in our Western Region, the Horned Frog NW #4H and Horned Frog NW #5H, finished drilling operations last week and were drilled to total measured depths of 19,716 and 19,672 feet, respectively. Fracture stimulation operations are to begin next week with average proppant concentrations of 2,000 pounds per foot. These wells should begin flowback operations in mid-late April. Lonestar has a 100% WI and 75% NRI in these wells.

EAGLE FORD SHALE TREND- CENTRAL REGION

In our Central Region, production for the fourth quarter of 2018 averaged approximately 5,991 Boe per day, a 56% increase over the prior year. The continued growth of the region was driven by the drilling and completion 2 gross / 1.3 net wells in the Hawkeye area in addition to production acquired in our Sooner Acquisition.

The acquisition, which occurred in November 2018, is 95% operated, included approximately 3,071 gross acres (2,693 net acres) and approximately 800 BOE/d of production on the date of the acquisition. It provides the Company with 26 drilling locations and expands Lonestar’s Eagle Ford footprint into its 11^th county, DeWitt. The Company plans to drill its first 3 gross / 3.0 net wells during the third quarter of 2019.

In December, the Company began flowback operations on the Hawkeye #24H and Hawkeye #25H. These wells were drilled to total measured depths of 20,050 and 19,665 feet, respectively. The Hawkeye #24H and #25H wells were fracture-stimulated in engineered completions using diverters with an average proppant concentration of 1,517 pounds per foot over 37 stages and 33 stages, respectively. The Hawkeye #24H was completed with a perforated interval of 10,407 feet and tested 937 Bbls/d of oil and 444 Mcf/d of natural gas, or 1,038 Boe/d (three-stream) on a 28/64’’ choke. The Hawkeye #25H was completed with a perforated interval of 9,901 feet and tested 912 Bbls/d of oil and 385 Mcf/d of natural gas, or 1,000 Boe/d (three-stream) on a 26/64’’ choke. Collectively, these wells have average Max-30 IP’s of 764 Bbls/d oil and 397 Mcf/d of natural gas, or 855 Boe/d (three-stream) on a 32/64’’ choke. Lonestar holds a 68% WI / 53% NRI in these wells.

During 2019 the Company plans to drill 12 gross / 11.2 net wells in its Central region. Lonestar is currently drilling its first set of wells in the region for 2019, the Georg #3H, Georg #4H, Georg #5H, and Georg #6H. These wells have planned total measured depths of approximately 16,400 feet and expected perforated intervals of 7,250 feet. Lonestar has an 80% WI / 61% NRI in these wells.

EAGLE FORD SHALE TREND- EASTERN REGION

In our Eastern Region, production for the fourth quarter of 2018 averaged approximately 336 Boe per day, a 43% decrease over the prior year. The Company did not complete any wells in this region in 2018. Lonestar plans to return to Brazos during 2Q19 to drill a 1 gross / 0.5 net well. Lonestar will have a 50% WI / 39% NRI in this well.

NON-GAAP FINANCIAL MEASURES (Unaudited)

Reconciliation of Non-GAAP Financial Measures

Adjusted EBITDAX

Adjusted EBITDAX is not a measure of net income as determined by GAAP. Adjusted EBITDAX is a supplemental non-GAAP financial measure that is used by management and external users of the Company’s consolidated financial statements, such as industry analysts, investors, lenders and rating agencies. The Company defines Adjusted EBITDAX as net (loss) income before depreciation, depletion, amortization and accretion, exploration costs, non-recurring costs, (gain) loss on sales of oil and natural gas properties, impairment of oil and gas properties, stock-based compensation, interest expense, income tax (benefit) expense, rig standby expense, other income (expense), unrealized (gain) loss on derivative financial instruments and unrealized (gain) loss on warrants.

Management believes Adjusted EBITDAX provides useful information to investors because it assists investors in the evaluation of the Company’s operating performance and comparison of the results of the Company’s operations from period to period without regard to its financing methods or capital structure. The Company excludes the items listed above from net income in arriving at Adjusted EBITDAX to eliminate the impact of certain non-cash items or because these amounts can vary substantially from company to company within its 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. 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. The Company’s computations of Adjusted EBITDAX may not be comparable to other similarly titled measures of other companies.

The following table presents a reconciliation of Adjusted EBITDAX to the GAAP financial measure of net income (loss) for each of the periods indicated.

Adjusted Net Income (Loss)

Adjusted net income (loss) comparable to analysts’ estimates as set forth in this release represents income or loss from operations before income taxes adjusted for certain non-cash items (detailed in the accompanying table) less income taxes. We believe adjusted net income (loss) is calculated on the same basis as analysts’ estimates and that many investors use this published research in making investment decisions and evaluating operational trends of the Company and its performance relative to other oil and gas producing companies. Diluted earnings per share (adjusted) as set forth in this release represents adjusted net income (loss) comparable to analysts’ estimates on a diluted per share basis.

The following table presents a reconciliation of Adjusted Net Income (Loss) to the GAAP financial measure of net income (loss) before taxes for each of the periods indicated.
