Tracker Acquisition and Board Appointment



At the Company’s Annual Meeting of Stockholders held on

Tuesday, July 20, 2021

, its stockholders approved the issuance of 6.2 million shares of Class A Common Stock, which were issued in the closing of the Tracker Acquisition.  As of

July 20, 2021

, and as adjusted for closing of the Tracker Acquisition, Earthstone had 50,493,800 outstanding Class A shares and 34,397,877 outstanding Class B shares for a total of 84,891,677 outstanding Class A & Class B shares.

Further, the stockholders approved an amendment to the Company’s Third Amended and Restated Certificate of Incorporation to increase the authorized size of the Board of Directors of Earthstone from nine to eleven members.  Subsequently, the Board increased the size of the Board from nine members to ten members and appointed

Robert J. Anderson

, the Company’s President and CEO, to fill the vacancy effective

July 20, 2021

.

The aggregate purchase price of the Tracker Acquisition was approximately

$126.5 million

at signing of the purchase and sale agreement, consisting of

$81.6 million

in cash and 6.2 million shares of Earthstone’s Class A common stock valued at

$44.9 million

based on a closing share price of

$7.24

on

March 30

, 2021.  Cash consideration paid at closing was

$59.6 million

, reflecting both the purchase price adjustment estimated prior to closing and the deposit paid at signing.

The low-cost, low-decline, high-margin assets acquired from the Tracker Acquisition are proximately located and complementary to Earthstone’s existing operated assets, adding significant producing asset value with a Company estimated PV-10 value of mid-year 2021 proved developed reserves of

$169.0 million

, based on NYMEX strip pricing and differentials as of

June 30

, 2021.  We also obtained further economic upside from 49 high-graded drilling locations which the Company estimates to provide IRRs of ~56% at

$60

Updated 2021 Guidance



The Company has revised its 2021 capital budget to include the addition of a second rig that is expected to commence operations in early August and now expects to spend

$130

–

$140 million

.  This program is expected to result in spudding 30 gross / 26.2 net operated wells and bringing 20 gross / 16.1 net operated wells and 0.7 net non-operated wells online in 2021 on its acreage in the Midland Basin.

Based on its 2021 capital budget, operating plan, and existing service costs, along with current commodity prices and hedges, the Company expects to generate significant positive free cash flow

⁴

in 2021. The Company’s capital budget excludes acquisitions.

Management Comments




Robert J. Anderson

, President and Chief Executive Officer of Earthstone, stated, “First off, I want to thank my fellow board members for this appointment to the Earthstone Board of Directors.  I am honored to have worked with this distinguished group for a number of years in my capacity as an officer and look forward to working even closer with them as we continue to build Earthstone.  We have had an exciting and productive first half of 2021, and we are entering the second half with a significant increase in operational scale, production, cash flow and most importantly, in value.  We have invested an estimated

$360 million

in aggregate acquisitions so far this year, and combined with a substantial increase in commodity prices, we have seen a significant increase in production volumes, cash flows and in estimated proved reserves and PV-10 value. We pride ourselves on targeting and completing acquisitions at highly accretive valuations and are focused on continuing to do so in the second half of the year.

“Our conservative approach to funding acquisitions with an appropriate mix of debt and equity has allowed us to maintain strong liquidity and low leverage while building significant scale.  We expect to have nearly doubled our daily production volumes compared to 2020 levels, all while adding minimal G&A.  The combination of continued improvements in operational and corporate efficiencies has allowed us to continue to drive down per unit costs, as we aim to maximize margins.

Mr. Anderson continued “With our increased production base, cash flow and economic drilling inventory, the addition of a second rig will further develop our growing drilling inventory, primarily impacting production volumes in 2022 and beyond.  Our updated capital program is designed to allow spending within cash flow and is expected to generate significant free cash flow in 2021.  We look forward to fully integrating the Tracker Acquisition assets in the coming months and expect a similarly smooth integration as we achieved with the IRM assets acquired in January.  We recently finished drilling operations on our initial pad on the IRM assets ahead of schedule and under our estimated costs.  As we move forward, we will continue to focus on cost-efficient drilling and completion operations as we look to create value through the drillbit.”

June 30, 2021

July 20, 2021

, we had an estimated

$0.5 million

in cash and

$301.0 million

of long-term debt outstanding under our credit facility with a borrowing base of

$550 million

. With the

$249.0 million

of undrawn borrowing base capacity and

Operational Update



The Company completed three gross (2.1 net) wells in the second quarter on the Hamman 45 pad in

Midland County

in the Jo Mill, Lower Spraberry and Wolfcamp B zones.  The wells began flowing back recently and continue to clean-up but have not yet reached peak IP-30 day rates.  We expect to complete and turn to sales the recently drilled 4-well Pearl Jam pad (95% working interest) in

Midland County

late in the third quarter.  These are the Company’s first wells drilled on the recently acquired IRM acreage.  Subsequent to drilling on the Pearl Jam pad, the rig was moved to western

Reagan County

in early July to drill a 4-well pad, then is expected to move to

Upton County

to drill a 4-well pad before being moved to

Midland County

late in 2021.  The Company plans to deploy a second rig in early August, beginning in

Upton County

.

Mid-Year 2021 SEC Estimated Proved Reserves



Earthstone Stand-Alone Mid-Year 2021 Estimated Proved Reserves Highlights:

• Proved Reserves of 111.4 MMBoe with corresponding PV-10 value of
  
  $1,032 million
  
• Proved Reserves are 54% oil, 24% natural gas liquids, and 22% natural gas
• Proved Reserves are 55% Proved Developed and 45% Proved Undeveloped

As shown in the table below, the Company’s estimated proved reserves at mid-year 2021, which were prepared in accordance with Securities and Exchange Commission (“SEC”) guidelines by the Company, were approximately 111.4 million barrels of oil equivalent (“MMBoe”).

SEC rules require that calculations of economically recoverable reserves use the unweighted average price on the first day of the month for the prior twelve-month period. The resulting oil and natural gas prices used for the Company’s 2021 mid-year internal reserve report, prior to adjusting for quality and basis differentials, were

$49.78

per barrel and

$2.428

per million British Thermal Units (“MMBtu”), respectively. SEC prices net of differentials were

$48.88

per barrel,

$14.58

per equivalent barrel of NGL and

Non-GAAP Financial Measure

Unaudited

The non-GAAP financial measure of PV-10, as defined and presented below, is intended to provide readers with meaningful information that supplements our financial statements prepared in accordance with accounting principles generally accepted in

the United States

(“GAAP”).

PV-10 is derived from the standardized measure of discounted future net cash flows (“Standardized Measure”), which is the most directly comparable financial measure under GAAP. PV-10 is a computation of the Standardized Measure on a pre-tax basis. PV-10 is equal to the Standardized Measure at the applicable date, before deducting future income taxes, discounted at 10%. We believe that the presentation of PV-10 is relevant and useful to investors because it presents the discounted future net cash flows attributable to our estimated net proved reserves prior to taking into account future corporate income taxes, and it is a useful measure for evaluating the relative monetary significance of our oil and natural gas properties. Further, investors may utilize the measure as a basis for comparison of the relative size and value of our reserves to other companies. We use this measure when assessing the potential return on investment related to our oil and natural gas properties. PV-10, however, is not a substitute for the Standardized Measure. Our PV-10 measure and the Standardized Measure do not purport to present the fair value of our oil and natural gas reserves.

The following table provides a reconciliation of PV-10 of the Company’s estimated proved reserves to the Standardized Measure as of

June 30, 2021

and not including the assets acquired in the Tracker Acquisition (in thousands):
