The following discussion analyzes our financial condition and results of
operations and should be read in conjunction with the Consolidated Financial
Statements and Notes to Consolidated Financial Statements, wherein WES Operating
is fully consolidated, and which are included under Part I, Item 1 of this
quarterly report, and the historical consolidated financial statements, and the
notes thereto, which are included under Part II, Item 8 of the 2020 Form 10-K as
filed with the SEC on February 26, 2021.
The Partnership's assets include assets owned and ownership interests accounted
for by us under the equity method of accounting, through our 98.0% partnership
interest in WES Operating, as of March 31, 2021 (see Note 7-Equity Investments
in the Notes to Consolidated Financial Statements under Part I, Item 1 of this
Form 10-Q). We also own and control the entire non-economic general partner
interest in WES Operating GP, and our general partner is owned by Occidental.

              CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

We have made in this Form 10-Q, and may make in other public filings, press

Weather-related impacts. In February 2021, the U.S. experienced winter storm
Uri, bringing extreme cold temperatures, ice, and snow to the central U.S.,
including Texas, and in March 2021, Colorado experienced a historic blizzard.
Winter storm Uri adversely affected our volumes for approximately ten days and
the blizzard in Colorado likewise disrupted our assets in that state. We
estimate the impact of these weather events to have reduced net income and
Adjusted EBITDA (as defined under the caption Key Performance Metrics within
this Item 2) for the quarter ended March 31, 2021, by approximately $30 million
due to lower volumes, the impact of commodity-prices, and higher operating
expenses related to utilities. The estimated impact of the adverse winter
weather on our operations and financial results may change and those changes may
be material. Any additional inclement weather in the future, or other adverse
conditions, including resolution of litigation and other legal disputes and the
COVID-19 pandemic and resulting mitigation factors, may have an adverse impact
on our operations and financial results.

COVID-19. During 2020, the global outbreak of COVID-19 caused a sharp decline in
the worldwide demand for oil, natural gas, and NGLs, which contributed
significantly to commodity-price declines and oversupplied commodities markets.
These market dynamics have had an adverse impact on producers that provide
throughput into our systems, and we have experienced decreased throughput at
many of our locations.
Additionally, many of our employees have been and may continue to be subject to
pandemic-related work-from-home requirements, which require us to take
additional actions to ensure that the number of personnel accessing our network
remotely does not lead to excessive cyber-security risk levels. Similarly, we
are working continually to ensure operational changes that we have made to
promote the health and safety of our personnel during this pandemic do not
unduly disrupt intracompany communications and key business processes. We
consider our risk-mitigation efforts adequate; however, the ultimate impact of
the ongoing pandemic is unpredictable, with direct and indirect impacts to our
business.
WES continues to monitor the COVID-19 situation closely, and as state and
federal governments issue additional guidance, we will update our own policies
in response to ensure the safety and health of our workforce and communities.
The federal government has provided guidance to states on how to safely return
personnel to the workplace, which we are following as our workforce returns to
WES locations. All WES facilities, including field locations, have been
conducting enhanced routine cleaning and disinfecting of common areas and
frequently touched surfaces using CDC- and EPA-approved products. Our
return-to-work protocols include daily required application-based health
self-assessments that must be completed prior to accessing WES work locations.

Commodity purchase and sale agreements. Effective April 1, 2020, changes to
marketing-contract terms with AESC terminated AESC's prior status as an agent of
the Partnership for third-party sales and established AESC as a customer of the
Partnership. Accordingly, we no longer recognize service revenues and/or product
sales revenues and the equivalent cost of product expense for the marketing
services performed by AESC. Year-over-year variances for the three months ended
March 31, 2021, include the following impacts related to this change (i)
decrease of $45.9 million in Service revenues - fee based, (ii) decrease of
$20.4 million in Product sales, and (iii) decrease of $66.3 million in Cost of
product expense. These changes had no impact to Operating income (loss), Net
income (loss), the balance sheets, cash flows, or any non-GAAP metric used to
evaluate our operations (see Key Performance Metrics within this Item 2). See
Note 6-Related-Party Transactions in the Notes to Consolidated Financial
Statements under Part I, Item 1 of this Form 10-Q.

                                    OUTLOOK

We expect our business to continue to be affected by the below-described key
trends and uncertainties. Our expectations are based on assumptions made by us
and information currently available to us. To the extent our underlying
assumptions about, or interpretations of, available information prove incorrect,
our actual results may vary materially from expected results.

Impact of crude-oil, natural-gas, and NGLs prices. Crude-oil, natural-gas, and
NGLs prices can fluctuate significantly, and have done so over time.
Commodity-price fluctuations affect the level of our customers' activities and
our customers' allocations of capital within their own asset portfolios. During
the first quarter of 2020, oil and natural-gas prices decreased significantly,
driven by the expectation of increased supply and sharp declines in demand
resulting from the worldwide macroeconomic downturn that followed the global
outbreak of COVID-19. For example, NYMEX West Texas Intermediate crude-oil daily
settlement prices ranged from a high of $63.27 per barrel in January 2020 to a
low below $20.00 per barrel in April 2020, with prices rebounding to $59.16 per
barrel at March 31, 2021. While the extent and duration of the recent
commodity-price volatility cannot be predicted, potential impacts to our
business include the following:

•We have exposure to increased credit risk to the extent any of our customers, including Occidental, is in financial distress. See Liquidity and Capital Resources-Credit risk within this Item 2 for additional information.



•An extended period of diminished earnings may restrict our ability to fully
access our RCF, which contains various customary covenants, certain events of
default, and a maximum consolidated leverage ratio based on Adjusted EBITDA (as
defined in the covenant) related to the trailing twelve-month period. Further,
any future waivers or amendments to the RCF also may trigger pricing increases
for available credit. See Liquidity and Capital Resources-Debt and credit
facilities within this Item 2 for additional information.

•As of March 31, 2021, it is reasonably possible that future commodity-price
declines, prolonged depression of commodity prices, changes to producers'
drilling plans in response to lower prices, and potential producer bankruptcies
could result in future long-lived asset impairments.

To the extent producers continue with development plans in our areas of
operation, we will continue to connect new wells or production facilities to our
systems to maintain throughput on our systems and mitigate the impact of
production declines. However, our success in connecting additional wells or
production facilities is dependent on the activity levels of our customers.
Additionally, we will continue to evaluate the crude-oil, NGLs, and natural-gas
price environments and adjust our capital spending plans to reflect our
customers' anticipated activity levels, while maintaining appropriate liquidity
and financial flexibility.

                         ACQUISITIONS AND DIVESTITURES

Fort Union and Bison facilities. In October 2020, we (i) sold our 14.81%
interest in Fort Union, which was accounted for under the equity method of
accounting, and (ii) entered into an option agreement to sell the Bison treating
facility, located in Northeast Wyoming, to a third party, initially exercisable
during the first quarter of 2021 and subsequently extended to May 9, 2021.
During the second quarter of 2021, the third party exercised its option to
purchase the Bison treating facility and it satisfied the held-for-sale
criteria. The sale is expected to close in the second quarter of 2021. See
Note 3-Acquisitions and Divestitures in the Notes to Consolidated Financial
Statements under Part I, Item 1 of this Form 10-Q for further information.

Natural-gas assets



Gathering, treating, and transportation throughput decreased by 2 MMcf/d and 20
MMcf/d compared to the three months ended December 31, 2020, and March 31, 2020,
respectively, primarily due to (i) production declines and the impact of winter
storm Uri at the Springfield gas-gathering system and (ii) lower throughput at
the Bison facility due to production declines in the area. These decreases were
offset partially by increased production in areas around the Marcellus Interest
systems.
Processing throughput increased by 67 MMcf/d compared to the three months ended
December 31, 2020, primarily due to an additional third-party connection to
Latham Train II at the DJ Basin complex beginning January 1, 2021, partially
offset by lower production and the impact of winter storm Uri at the West Texas
complex.

Service revenues - fee based



Service revenues - fee based decreased by $31.5 million compared to the three
months ended December 31, 2020, primarily due to (i) $10.2 million at the DBM
water systems from decreased throughput, including the impact of winter storm
Uri, and a lower average fee resulting from a cost-of-service rate
redetermination effective January 1, 2021, (ii) $8.9 million at the Springfield
system due to annual cost-of-service rate adjustments that increased revenue in
the fourth quarter of 2020, (iii) $6.7 million at the DBM oil system and $4.9
million at the West Texas complex from decreased throughput, including the
impact of winter storm Uri, and (iv) $5.5 million at the DJ Basin complex from a
lower average gathering fee, partially offset by increased throughput. These
decreases were offset partially by an increase of $8.2 million at the DJ Basin
oil system due to an annual cost-of-service rate adjustment made during the
fourth quarter of 2020 and increased throughput.
Service revenues - fee based decreased by $129.1 million compared to the three
months ended March 31, 2020, primarily due to (i) $45.9 million, resulting from
a change in accounting for the marketing contracts with AESC effective April 1,
2020 (see Executive Summary-Commodity purchase and sale agreements within this
Item 2), (ii) $22.7 million at the DJ Basin complex from a lower average
gathering fee and decreased throughput, (iii) $20.9 million at the West Texas
complex from decreased throughput, including the impact of winter storm Uri,
(iv) $16.8 million at the DBM oil system from decreased throughput, including
the impact of winter storm Uri, and the effect of the straight-line treatment of
lease revenue under the operating and maintenance agreement with Occidental, and
(v) $13.1 million at the DBM water systems from decreased throughput, including
the impact of winter storm Uri, and a lower average fee resulting from a
cost-of-service rate redetermination effective January 1, 2021.

Service revenues - product based



Service revenues - product based increased by $18.5 million and $15.7 million
compared to the three months ended December 31, 2020, and March 31, 2020,
respectively, primarily due to (i) $8.6 million and $4.2 million, respectively,
at the West Texas complex due to an increase in electricity-related rates billed
to customers during winter storm Uri, (ii) $3.6 million and $3.6 million,
respectively, at the Hilight system due to increased prices, (iii) $3.3 million
and $4.0 million, respectively, at the DJ Basin complex due to increased
third-party volumes, and (iv) increased pricing across several systems.

Natural-gas sales



Natural-gas sales increased by $14.8 million compared to the three months ended
December 31, 2020, primarily due to increases of $15.4 million at the West Texas
complex and $3.7 million at the MGR assets attributable to increases in average
prices. These increases were offset partially by a decrease of $4.9 million at
the DJ Basin complex attributable to a decrease in volumes, partially offset by
increased average prices.
Natural-gas sales increased by $10.9 million compared to the three months ended
March 31, 2020, primarily due to increases of (i) $16.3 million at the West
Texas complex attributable to an increase in average prices, partially offset by
decreased volumes sold, (ii) $4.4 million at the MGR assets attributable to an
increase in average prices, and (iii) $1.4 million resulting from a change in
accounting for the marketing contracts with AESC effective April 1, 2020 (see
Executive Summary-Commodity purchase and sale agreements within this Item 2).
These increases were offset partially by a decrease of $10.5 million at the DJ
Basin complex attributable to a decrease in volumes, partially offset by
increased average prices.

NGLs sales



NGLs sales increased by $25.9 million compared to the three months ended
December 31, 2020, primarily due to increases of (i) $17.6 million at the West
Texas Complex attributable to an increase in average prices, partially offset by
decreased volumes sold, (ii) $2.5 million at the Chipeta complex attributable to
an increase in average prices, and (iii) $2.4 million at the DJ Basin complex
attributable to an increase in average prices and volumes sold.
NGLs sales increased by $3.3 million compared to the three months ended March
31, 2020, primarily due to increases of (i) $19.1 million at the West Texas
complex attributable to an increase in average prices, partially offset by
decreased volumes sold and (ii) $3.6 million at the Chipeta complex and $2.6
million at the Granger complex attributable to increases in average prices.
These increases were offset partially by a decrease of $21.8 million resulting
from a change in accounting for the marketing contracts with AESC effective

Equity income, net - related parties decreased by $9.2 million compared to the
three months ended March 31, 2020, primarily due to a decrease in equity income
from Whitethorn LLC related to commercial activities and lower volumes. In
addition, decreased equity income from lower volumes at White Cliffs, Cactus II,
and FRP were mostly offset by increased equity income from higher volumes at Red
Bluff Express and Saddlehorn.

securing its own dedicated workforce as of December 2019 and the related
transition activities.

Property and other taxes



Property and other taxes increased by $3.3 million compared to the three months
ended December 31, 2020, due to ad valorem tax increases of $4.6 million at the
West Texas complex primarily due to capital projects being placed into service.
This increase was offset partially by ad valorem tax decreases of $2.5 million
at the DJ Basin complex primarily attributable to favorable differences between
actual and estimated tax payments related to the 2020 fiscal year.
Property and other taxes decreased by $4.1 million compared to the three months
ended March 31, 2020, primarily due to ad valorem tax decreases at the DJ Basin

Interest income



Interest income - Anadarko note receivable decreased by $4.2 million compared to
the three months ended March 31, 2020, due to the exchange of the Anadarko note
receivable under the Unit Redemption Agreement in September 2020. See
Note 6-Related-Party Transactions in the Notes to Consolidated Financial

Interest expense

Interest expense decreased by $2.8 million compared to the three months ended
December 31, 2020, primarily due to (i) $2.0 million of lower interest incurred
on the 5.375% Senior Notes due 2021 that were called on March 1, 2021 and (ii)
an increase of $2.2 million in capitalized interest due to a change in the mix
of active projects. These decreases to interest expense were offset partially by
increases of $1.4 million due to higher effective interest rates resulting from
credit-rating downgrades on the 3.100% Senior Notes due 2025, 4.050% Senior
Notes due 2030, 5.250% Senior Notes due 2050, and Floating-Rate Senior Notes due
2023.
Interest expense increased by $9.9 million compared to the three months ended
March 31, 2020, primarily due to (i) $13.8 million of additional interest
incurred from higher effective interest rates resulting from credit-rating
downgrades and a full quarter of expense on the 3.100% Senior Notes due 2025,
4.050% Senior Notes due 2030, and 5.250% Senior Notes due 2050 and (ii) a
decrease of $3.9 million in capitalized interest due to decreased capital
expenditures. These increases were offset partially by decreases of (i) $4.2
million due to lower outstanding balances on the 5.375% Senior Notes due 2021
that were called on March 1, 2021, 4.000% Senior Notes due 2022, and
Floating-Rate Senior Notes due 2023 and (ii) $3.6 million due to lower
outstanding borrowings under the RCF in 2021. See Liquidity and Capital

We are not a taxable entity for U.S. federal income tax purposes; therefore, our
federal statutory rate is zero percent. However, income apportionable to Texas
is subject to Texas margin tax.
For all periods presented, the variance from the federal statutory rate
primarily was due to our Texas margin tax liability.

(1)Increases or decreases refer to the comparison of the three months ended
March 31, 2021, to the three months ended March 31, 2020.
(2)Average for period. Calculated as Adjusted gross margin for natural-gas
assets, divided by total throughput (MMcf/d) attributable to WES for natural-gas
assets.
(3)Average for period. Calculated as Adjusted gross margin for crude-oil and
NGLs assets, divided by total throughput (MBbls/d) attributable to WES for
crude-oil and NGLs assets.
(4)Average for period. Calculated as Adjusted gross margin for produced-water
assets, divided by total throughput (MBbls/d) attributable to WES for
produced-water assets.

Adjusted gross margin. We define Adjusted gross margin attributable to Western
Midstream Partners, LP ("Adjusted gross margin") as total revenues and other
(less reimbursements for electricity-related expenses recorded as revenue), less
cost of product, plus distributions from equity investments, and excluding the
noncontrolling interest owners' proportionate share of revenues and cost of
product. We believe Adjusted gross margin is an important performance measure of
our operations' profitability and performance as compared to other companies in
the midstream industry. Cost of product expenses include (i) costs associated
with the purchase of natural gas and NGLs pursuant to our percent-of-proceeds,
percent-of-product, and keep-whole contracts, (ii) costs associated with the
valuation of gas imbalances, and (iii) costs associated with our obligations
under certain contracts to redeliver a volume of natural gas to shippers, which
is thermally equivalent to condensate retained by us and sold to third parties.
To facilitate investor and industry analyst comparisons between us and our
peers, we also disclose per-Mcf Adjusted gross margin for natural-gas assets,
per-Bbl Adjusted gross margin for crude-oil and NGLs assets, and per-Bbl
Adjusted gross margin for produced-water assets.
Adjusted gross margin decreased by $33.8 million compared to the three months
ended December 31, 2020, primarily due to (i) decreased throughput and a lower
average fee resulting from a cost-of-service rate redetermination effective
January 1, 2021, at the DBM water systems, (ii) a decrease in distributions from
Whitethorn LLC and Cactus II, (iii) an annual cost-of-service rate adjustment at
the Springfield system that increased revenues in the fourth quarter of 2020,
and (iv) decreased throughput at the DBM oil system. These decreases were
partially offset by an increase at the DJ Basin oil system due to an annual
cost-of-service rate adjustment made during the fourth quarter of 2020.
Adjusted gross margin decreased by $86.7 million compared to the three months
ended March 31, 2020, primarily due to (i) decreased throughput at the West
Texas complex and DJ Basin oil system, (ii) a lower average gathering fee and
decreased throughput at the DJ Basin complex, (iii) decreased throughput and the
effect of the straight-line treatment of lease revenue under the operating and
maintenance agreement with Occidental at the DBM oil system, and (iv) decreased
throughput and a lower average fee resulting from a cost-of-service rate
redetermination effective January 1, 2021 at the DBM water systems.
Per-Mcf Adjusted gross margin for natural-gas assets increased by $0.03 compared
to the three months ended March 31, 2020, primarily due to a higher
cost-of-service rate effective January 1, 2021, at the West Texas complex,
partially offset by decreased throughput at the DJ Basin complex, which has a
higher-than-average per-Mcf margin as compared to our other natural-gas assets.

Per-Bbl Adjusted gross margin for crude-oil and NGLs assets decreased by $0.24
compared to the three months ended December 31, 2020, primarily due to (i) an
annual cost-of-service rate adjustment at the Springfield system that increased
revenues in the fourth quarter of 2020 and (ii) a decrease in distributions from
Cactus II. These decreases were partially offset by an annual cost-of-service
rate adjustment made during the fourth quarter of 2020 and increased throughput
at the DJ Basin oil system.
Per-Bbl Adjusted gross margin for crude-oil and NGLs assets increased by $0.03
compared to the three months ended March 31, 2020, primarily due to a higher
cost-of-service rate effective January 1, 2021, at the DJ Basin oil system,
partially offset by (i) decreased throughput and the effect of the straight-line
treatment of lease revenue under the operating and maintenance agreement with
Occidental at the DBM oil system, which has a higher-than-average per-Bbl margin
as compared to our other crude-oil and NGLs assets and (ii) a decrease in
distributions from Cactus II.
Per-Bbl Adjusted gross margin for produced-water assets decreased by $0.06 and
$0.05 compared to the three months ended December 31, 2020, and March 31, 2020,
respectively, primarily due to a lower average fee resulting from a
cost-of-service rate redetermination effective January 1, 2021.

Adjusted EBITDA. We define Adjusted EBITDA attributable to Western Midstream
Partners, LP ("Adjusted EBITDA") as net income (loss), plus (i) distributions
from equity investments, (ii) non-cash equity-based compensation expense, (iii)
interest expense, (iv) income tax expense, (v) depreciation and amortization,
(vi) impairments, and (vii) other expense (including lower of cost or market
inventory adjustments recorded in cost of product), less (i) gain (loss) on
divestiture and other, net, (ii) gain (loss) on early extinguishment of debt,
(iii) income from equity investments, (iv) interest income, (v) income tax
benefit, (vi) other income, and (vii) the noncontrolling interest owners'
proportionate share of revenues and expenses. We believe the presentation of
Adjusted EBITDA provides information useful to investors in assessing our
financial condition and results of operations and that Adjusted EBITDA is a
widely accepted financial indicator of a company's ability to incur and service
debt, fund capital expenditures, and make distributions. Adjusted EBITDA is a
supplemental financial measure that management and external users of our
consolidated financial statements, such as industry analysts, investors,
commercial banks, and rating agencies, use, among other measures, to assess the
following:

•our operating performance as compared to other publicly traded partnerships in
the midstream industry, without regard to financing methods, capital structure,
or historical cost basis;

•the ability of our assets to generate cash flow to make distributions; and

•the viability of acquisitions and capital expenditures and the returns on investment of various investment opportunities.



Adjusted EBITDA decreased by $40.9 million compared to the three months ended
December 31, 2020, primarily due to (i) a $54.5 million increase in cost of
product (net of lower of cost or market inventory adjustments), (ii) an $8.0
million decrease in distributions from equity investments, (iii) $7.0 million
increase in general and administrative expenses excluding non-cash equity-based
compensation expense, and (iv) $3.3 million increase in property taxes. These
amounts were offset partially by (i) a $27.5 million increase in total revenues
and other and (ii) a $3.9 million decrease in operation and maintenance
expenses.
Adjusted EBITDA decreased by $70.5 million compared to the three months ended
March 31, 2020, primarily due to (i) a $99.3 million decrease in total revenues
and other, (ii) a $4.7 million decrease in distributions from equity
investments, and (iii) a $3.2 million increase in general and administrative
expenses excluding non-cash equity-based compensation expense. These amounts
were offset partially by (i) an $18.9 million decrease in operation and
maintenance expenses, (ii) a $14.1 million decrease in cost of product (net of
lower of cost or market inventory adjustments), and (iii) a $4.1 million
decrease in property taxes. The above-described variances in cost of product and
total revenues and other include the impacts resulting from a change in
accounting for the marketing contracts with AESC effective April 1, 2020, which
had no net impact on Adjusted EBITDA (see Executive Summary-Commodity purchase
and sale agreements within this Item 2).

Free cash flow. We define "Free cash flow" as net cash provided by operating
activities less total capital expenditures and contributions to equity
investments, plus distributions from equity investments in excess of cumulative
earnings. Management considers Free cash flow an appropriate metric for
assessing capital discipline, cost efficiency, and balance-sheet strength.
Although Free cash flow is the metric used to assess WES's ability to make
distributions to unitholders, this measure should not be viewed as indicative of
the actual amount of cash that is available for distributions or planned for
distributions for a given period. Instead, Free cash flow should be considered
indicative of the amount of cash that is available for distributions, debt
repayments, and other general partnership purposes.
Free cash flow decreased by $250.9 million compared to the three months ended
December 31, 2020, primarily due to (i) a decrease of $244.0 million in net cash
provided by operating activities and (ii) an increase of $9.0 million in capital
expenditures.
Free cash flow decreased by $0.8 million compared to the three months ended
March 31, 2020, primarily due to a decrease of $131.8 million in net cash
provided by operating activities, partially offset by (i) a decrease of $113.0
million in capital expenditures, (ii) a decrease of $10.9 million in
contributions to equity investments, and (iii) a $7.1 million increase in
distributions from equity investments in excess of cumulative earnings.

Reconciliation of non-GAAP financial measures. Adjusted gross margin, Adjusted
EBITDA, and Free cash flow are not defined in GAAP. The GAAP measure used by us
that is most directly comparable to Adjusted gross margin is operating income
(loss). Net income (loss) and net cash provided by operating activities are the
GAAP measures used by us that are most directly comparable to Adjusted EBITDA.
The GAAP measure used by us that is most directly comparable to Free cash flow
is net cash provided by operating activities. Our non-GAAP financial measures of
Adjusted gross margin, Adjusted EBITDA, and Free cash flow should not be
considered as alternatives to the GAAP measures of operating income (loss), net
income (loss), net cash provided by operating activities, or any other measure
of financial performance presented in accordance with GAAP. Adjusted gross
margin, Adjusted EBITDA, and Free cash flow have important limitations as
analytical tools because they exclude some, but not all, items that affect
operating income (loss), net income (loss), and net cash provided by operating
activities. Adjusted gross margin, Adjusted EBITDA, and Free cash flow should
not be considered in isolation or as a substitute for analysis of our results as
reported under GAAP. Our definitions of Adjusted gross margin, Adjusted EBITDA,
and Free cash flow may not be comparable to similarly titled measures of other
companies in our industry, thereby diminishing their utility as comparative
measures.
Management compensates for the limitations of Adjusted gross margin, Adjusted
EBITDA, and Free cash flow as analytical tools by reviewing the comparable GAAP
measures, understanding the differences between Adjusted gross margin, Adjusted
EBITDA, and Free cash flow compared to (as applicable) operating income (loss),
net income (loss), and net cash provided by operating activities, and
incorporating this knowledge into its decision-making processes. We believe that
investors benefit from having access to the same financial measures that our
management considers in evaluating our operating results.
The following tables present (i) a reconciliation of the GAAP financial measure
of operating income (loss) to the non-GAAP financial measure of Adjusted gross
margin, (ii) a reconciliation of the GAAP financial measures of net income
(loss) and net cash provided by operating activities to the non-GAAP financial
measure of Adjusted EBITDA, and (iii) a reconciliation of the GAAP financial
measure of net cash provided by operating activities to the non-GAAP financial
measure of Free cash flow:

                        LIQUIDITY AND CAPITAL RESOURCES

Our primary cash uses include quarterly distributions, debt service, capital
expenditures, customary operating expenses, and distributions to our
noncontrolling interest owners. Our sources of liquidity as of March 31, 2021,
included cash and cash equivalents, cash flows generated from operations,
available borrowing capacity under the RCF, and potential issuances of
additional equity or debt securities. We believe that cash flows generated from
these sources will be sufficient to satisfy our short-term working capital
requirements and long-term capital-expenditure requirements. The amount of
future distributions to unitholders will depend on our results of operations,
financial condition, capital requirements, and other factors, and will be
determined by the Board of Directors on a quarterly basis. We may rely on
external financing sources, including equity and debt issuances, to fund capital
expenditures and future acquisitions. However, we also may use operating cash
flows to fund capital expenditures or acquisitions, which could result in
borrowings under the RCF to pay distributions or to fund other short-term
working capital requirements.
Under our partnership agreement, we distribute all of our available cash (beyond
proper reserves as defined in our partnership agreement) within 55 days
following each quarter's end. Our cash flow and resulting ability to make cash
distributions are dependent on our ability to generate cash flow from
operations. Generally, our available cash is our cash on hand at the end of a
quarter after the payment of our expenses and the establishment of cash reserves
and cash on hand resulting from working capital borrowings made after the end of
the quarter. The general partner establishes cash reserves to provide for the
proper conduct of our business, including (i) reserves to fund future capital
expenditures, (ii) to comply with applicable laws, debt instruments, or other
agreements, or (iii) to provide funds for unitholder distributions for any one
or more of the next four quarters. We have made cash distributions to our
unitholders each quarter since our initial public offering in 2012. The Board of
Directors declared a cash distribution to unitholders for the first quarter of
2021 of $0.31500 per unit, or $133.0 million in the aggregate. The cash
distribution is payable on May 14, 2021, to our unitholders of record at the
close of business on April 30, 2021.
In November 2020, we announced a buyback program of up to $250.0 million of our
common units through December 31, 2021. The common units may be purchased from
time to time in the open market at prevailing market prices or in privately
negotiated transactions. The timing and amount of purchases under the program
will be determined based on ongoing assessments of capital needs, our financial
performance, the market price of the common units, and other factors, including
organic growth and acquisition opportunities and general market conditions. The
program does not obligate us to purchase any specific dollar amount or number of
units and may be suspended or discontinued at any time. During the quarter ended
March 31, 2021, we repurchased 1,115,808 common units on the open market for an
aggregate purchase price of $16.2 million. We canceled the units immediately
upon receipt. As of March 31, 2021, we had an authorized amount of $201.2
million remaining under the Purchase Program.
Management continuously monitors our leverage position and coordinates our
capital expenditures and quarterly distributions with expected cash inflows and
projected debt service requirements. We will continue to evaluate funding
alternatives, including additional borrowings and the issuance of debt or equity
securities, to secure funds as needed or to refinance maturing debt balances
with longer-term debt issuances. Our ability to generate cash flows is subject
to a number of factors, some of which are beyond our control. Read Risk Factors
under Part II, Item 1A of this Form 10-Q.

Working capital. As of March 31, 2021, we had a $120.9 million working capital
surplus, which we define as the amount by which current assets exceed current
liabilities. Working capital is an indication of liquidity and potential needs
for short-term funding. Working capital requirements are driven by changes in
accounts receivable and accounts payable and other factors such as credit
extended to, and the timing of collections from, our customers, and the level
and timing of our spending for acquisitions, maintenance, and other capital

Capital expenditures. Our business is capital intensive, requiring significant
investment to maintain and improve existing facilities or to develop new
midstream infrastructure. Capital expenditures includes maintenance capital
expenditures, which include those expenditures required to maintain existing
operating capacity and service capability of our assets, such as to replace
system components and equipment that have been subject to significant use over
time, become obsolete, or reached the end of their useful lives, to remain in
compliance with regulatory or legal requirements, or to complete additional well
connections to maintain existing system throughput and related cash flows; and
expansion capital expenditures, which include expenditures to construct new
midstream infrastructure and expenditures incurred to extend the useful lives of
our assets, reduce costs, increase revenues, or increase system throughput or
capacity from current levels, including well connections that increase existing
system throughput.
Capital expenditures in the consolidated statements of cash flows reflect
capital expenditures on a cash basis, when payments are made. Capital incurred
is presented on an accrual basis. Acquisitions and capital expenditures as

$4.8 million, respectively, of capitalized interest.

Capital expenditures decreased by $113.0 million for the three months ended
March 31, 2021, primarily due to decreases of (i) $56.2 million at the West
Texas complex primarily attributable to decreases in pipeline and well
connection projects, (ii) $21.4 million at the DJ Basin complex primarily
related to the completion of Latham Train II that commenced operations in the
first quarter of 2020 and decreases in pipeline, well connection, and
compression projects, (iii) $18.2 million at the DBM water systems primarily due
to reduced construction of additional water-disposal facilities and gathering
projects, and (iv) $16.5 million at the DBM oil system primarily related to the
completion of the Loving ROTF Trains III and IV that commenced operations during
the first and third quarters of 2020, respectively, and decreases in pipeline
and well connection projects.

Debt and credit facilities. As of March 31, 2021, the carrying value of
outstanding debt was $7.4 billion. See Note 11-Debt and Interest Expense in the
Notes to Consolidated Financial Statements under Part I, Item 1 of this Form
10-Q.

WES Operating Senior Notes. In mid-January 2020, WES Operating issued the
Fixed-Rate 3.100% Senior Notes due 2025, 4.050% Senior Notes due 2030, and
5.250% Senior Notes due 2050 and the Floating-Rate Senior Notes due 2023.
Including the effects of the issuance prices, underwriting discounts, and
interest-rate adjustments, the effective interest rates of the Senior Notes due
2025, 2030, and 2050, were 4.542%, 5.424%, and 6.629%, respectively, at
March 31, 2021. The interest rate on the Floating-Rate Senior Notes was 2.33% at
March 31, 2021. The effective interest rate of these notes is subject to
adjustment from time to time due to a change in credit rating.
During the first quarter of 2021, WES Operating redeemed the total principal
amount outstanding of the 5.375% Senior Notes due 2021 at par value, pursuant to
the optional redemption terms in WES Operating's indenture. At March 31, 2021,
WES Operating was in compliance with all covenants under the relevant governing
indentures.
We may, from time to time, seek to retire, rearrange, or amend some or all of
our outstanding debt or debt agreements through cash purchases, exchanges,
open-market repurchases, privately negotiated transactions, tender offers, or
otherwise. Such transactions, if any, will depend on prevailing market
conditions, our liquidity position and requirements, contractual restrictions,
and other factors. The amounts involved may be material.

Revolving credit facility. WES Operating's $2.0 billion senior unsecured
revolving credit facility is expandable to a maximum of $2.5 billion, and
matures in February 2025 for each extending lender. The non-extending lender's
commitments mature in February 2024 and represent $100.0 million out of $2.0
billion of total commitments from all lenders.
As of March 31, 2021, there were no outstanding borrowings and $5.1 million of
outstanding letters of credit, resulting in $2.0 billion of available borrowing
capacity under the RCF. At March 31, 2021, the interest rate on any outstanding
RCF borrowings was 1.61% and the facility-fee rate was 0.25%. At March 31, 2021,
WES Operating was in compliance with all covenants under the RCF.
The RCF contains certain covenants that limit, among other things, WES
Operating's ability, and that of certain of its subsidiaries, to incur
additional indebtedness, grant certain liens, merge, consolidate, or allow any
material change in the character of its business, enter into certain
related-party transactions and use proceeds other than for partnership purposes.
The RCF also contains various customary covenants, certain events of default,
and a maximum consolidated leverage ratio as of the end of each fiscal quarter
(which is defined as the ratio of consolidated indebtedness as of the last day
of a fiscal quarter to Consolidated EBITDA for the most-recent four-consecutive
fiscal quarters ending on such day) of 5.0 to 1.0, or a consolidated leverage
ratio of 5.5 to 1.0 with respect to quarters ending in the 270-day period
immediately following certain acquisitions. As a result of certain covenants
contained in the RCF, our capacity to borrow under the RCF may be limited.

Finance lease liabilities. During the first quarter of 2020, WES entered into
finance leases with third parties for equipment and vehicles extending through
2029. As of March 31, 2021, we have future finance-lease payments of
$6.3 million for the remainder of 2021 and a total of $28.2 million in years
thereafter.

  Table of Contents
Credit risk. We bear credit risk through exposure to non-payment or
non-performance by our counterparties, including Occidental, financial
institutions, customers, and other parties. Generally, non-payment or
non-performance results from a customer's inability to satisfy payables to us
for services rendered, minimum-volume-commitment deficiency payments owed, or
volumes owed pursuant to gas-imbalance agreements. We examine and monitor the
creditworthiness of customers and may establish credit limits for customers. A
substantial portion of our throughput is sourced from producers, including
Occidental, that recently received credit-rating downgrades. We are subject to
the risk of non-payment or late payment by producers for gathering, processing,
transportation, and disposal fees. Additionally, we continue to evaluate
counterparty credit risk and, in certain circumstances, are exercising our
rights to request adequate assurance.
We expect our exposure to the concentrated risk of non-payment or
non-performance to continue for as long as our commercial relationships with
Occidental generate a significant portion of our revenues. While Occidental is
our contracting counterparty, gathering and processing arrangements with
affiliates of Occidental on most of our systems include not just
Occidental-produced volumes, but also, in some instances, the volumes of other
working-interest owners of Occidental who rely on our facilities and
infrastructure to bring their volumes to market. We also are party to agreements
with Occidental under which Occidental is required to indemnify us for certain
environmental claims, losses arising from rights-of-way claims, failures to
obtain required consents or governmental permits, and income taxes with respect
to the assets previously acquired from Anadarko. See Note 6-Related-Party
Transactions in the Notes to Consolidated Financial Statements under Part I,
Item 1 of this Form 10-Q.
Our ability to make cash distributions to our unitholders may be adversely
impacted if Occidental becomes unable to perform under the terms of gathering,
processing, transportation, and disposal agreements; the contribution
agreements; or the Services Agreement.
