The discussion below, as well as other portions of this quarterly report on Form
10-Q, contain forward-looking statements within the meaning of Section 27A of
the Securities Act, Section 21E of the Exchange Act and the Private Securities
Litigation Reform Act of 1995. In addition, management may make forward-looking
statements orally or in other writing, including, but not limited to, in press
releases, quarterly earnings calls, executive presentations, in the annual
report to stockholders and in other filings with the SEC. Readers can usually
identify these forward-looking statements by the use of such words as "may,"
"will," "should," "likely," "plans," "projects," "expects," "anticipates,"
"believes" or similar words. These statements involve a number of risks and
uncertainties. Actual results could materially differ from those anticipated by
such forward-looking statements. For more discussion about risk factors that
could cause or contribute to such differences, see Part II, Item 7 "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
Part I, Item 1A "Risk Factors" in the Company's 2019 Form 10-K, Part II, Item 1A
"Risk Factors" in the Company's quarterly report on Form 10-Q for the period
ended June 30, 2020 and any updates contained herein. Forward-looking statements
reflect the information only as of the date on which they are made. The Company
does not undertake any obligation to update any forward-looking statements to
reflect future events, developments, or other information. If Vistra does update
one or more forward-looking statements, no inference should be drawn that
additional updates will be made regarding that statement or any other
forward-looking statements. This discussion is intended to clarify and focus on
our results of operations, certain changes in our financial position, liquidity,
capital structure and business developments for the periods covered by the
consolidated financial statements included under Item 1 of this quarterly report
on Form 10-Q for the three and nine months ended September 30, 2020. This
discussion should be read in conjunction with those consolidated financial
statements and the related notes and is qualified by reference to them.

The following discussion and analysis of our financial condition and results of
operations for the three and nine months ended September 30, 2020 and 2019
should be read in conjunction with our condensed consolidated financial
statements and the notes to those statements. Results are impacted by the
effects of the Ambit Transaction and the Crius Transaction (see Note 2 to the
Financial Statements). Operational results for four facilities retired in late
2019 were recast from the MISO segment to the Asset Closure segment (see Note 4
to the Financial Statements).

All dollar amounts in the tables in the following discussion and analysis are stated in millions of U.S. dollars unless otherwise indicated.

Critical Accounting Policies and Estimates



The Company's discussion and analysis of its financial position and results of
operations is based upon its consolidated financial statements. The preparation
of these consolidated financial statements requires estimation and judgment that
affect the reported amounts of revenue, expenses, assets and liabilities. The
Company bases its estimates on historical experience and on various other
factors that are believed to be reasonable under the circumstances, the results
of which form the basis for making judgments about the accounting for assets and
liabilities that are not readily apparent from other sources. If the estimates
differ materially from actual results, the impact on the consolidated financial
statements may be material. The Company's critical accounting policies are
disclosed in our 2019 Form 10-K.

Business

Vistra is a holding company operating an integrated retail and electric power
generation business primarily in markets throughout the U.S. Through our
subsidiaries, we are engaged in competitive energy market activities including
power generation, wholesale energy sales and purchases, commodity risk
management and retail sales of electricity and natural gas to end users.
Effective July 2, 2020, we changed our name from Vistra Energy Corp. to Vistra
Corp. (Vistra) to distinguish from companies that are involved in exploring for,
producing, refining, or transporting fossil fuels (many of which use "energy" in
their names) and to better reflect our integrated business model, which combines
a retail electricity and natural gas business focused on serving its customers
with new and innovative products and services and an electric power generation
business powering the communities we serve with safe, reliable power.

Operating Segments

Vistra has six reportable segments: (i) Retail, (ii) Texas, (iii) East, (iv)
West, (v) Sunset and (vi) Asset Closure. In the third quarter of 2020, Vistra
updated its reportable segments to reflect changes in how the Company's CODM
makes operating decisions, assesses performance and allocates resources.
Management believes that the revised reportable segments provide enhanced
transparency into the Company's long-term sustainable assets and its commitment
to managing the retirement of economically and environmentally challenged
plants. See Notes 1 and 17 to the Financial Statements for further information
concerning the updates to our reportable business segments.

Significant Activities and Events and Items Influencing Future Performance

Investments in Clean Energy and CO2 Reductions



In September 2020, we announced the planned development of 668 MW of solar
photovoltaic power generation facilities and 260 MW of battery ESS in Texas. See
Note 3 to the Financial Statements for a summary of our solar and battery energy
storage projects.

Also in September 2020, we announced our intention to retire all of our
remaining coal generation facilities in Illinois and Ohio and one natural gas
facility in Illinois no later than year-end 2027 due to economic challenges,
including incremental expenditures that would be required to comply with the CCR
rule and ELG rule (see Note 12 to the Financial Statements), and in furtherance
of our efforts to significantly reduce our carbon footprint. See Note 4 to the
Financial Statements for a summary of these planned generation retirements in
2025-2027 as well as our generation plant retirements in 2019.

COVID-19 Pandemic



With the global outbreak of the novel coronavirus (COVID-19) and the declaration
of a pandemic by the World Health Organization on March 11, 2020, the U.S.
government has deemed electricity generation, transmission and distribution as
"critical infrastructure" providing essential services during this global
emergency. As a provider of critical infrastructure, Vistra has an obligation to
provide critically needed power to homes, businesses, hospitals and other
customers. Vistra remains focused on protecting the health and well-being of its
employees and the communities in which it operates while assuring the continuity
of its business operations.

We have updated and implemented our company-wide pandemic plan to address
specific aspects of the COVID-19 pandemic to guide our emergency response,
business continuity, and the precautionary measures we are taking on behalf of
employees and the public. We will continue to monitor developments affecting
both our workforce and our customers, and we have taken, and will continue to
take, health and safety measures that we determine are necessary in order to
mitigate the impacts. To date, as a result of these business continuity
measures, the Company has not experienced material disruptions in our operations
due to COVID-19.

The fundamentals of the Company remain strong. Vistra believes it has sufficient
available liquidity to continue business operations during this volatile period.
As described under Available Liquidity, the Company has total available
liquidity of $2.557 billion as of September 30, 2020, consisting of cash on hand
and available capacity under our Revolving Credit Facility. In addition, the
maturities of our long-term debt are relatively modest until 2023. If the
Company experienced a significant reduction in revenues, the Company believes it
would have additional alternatives to maintain access to liquidity, including
capital expenditure reductions, reductions to planned voluntary debt repayments
and cost reductions. As a result of the Company's ongoing initiatives, the
Company believes it is well positioned to be able to respond to changes in
customer demand, regulation or other factors impacting the Company's business
related to the COVID-19 pandemic.

The COVID-19 pandemic presents potential new risks to the Company's business.
Although there have been logistical and other challenges to date, there has been
no material adverse impact on the Company's first, second or third quarter 2020
results of operations. The situation surrounding COVID-19 remains fluid and the
potential for a material impact on the Company's results of operations,
financial condition and liquidity increases the longer the virus impacts the
level of economic activity in the U.S. and globally. As a result, COVID-19 may
have a range of impacts on the Company's operations, the full extent and scope
of which are currently unknown. See Part II, Item 1A Risk Factors - The outbreak
of COVID-19, or the future outbreak of any other highly infectious or contagious
diseases, could have a material and adverse effect on our business, financial
condition, and results of operations.

In response to the economic and employment impacts of the COVID-19 outbreak,
various states have instituted moratoriums or other conditions on disconnections
for retail electricity customers. For example, in March and April 2020, the PUCT
issued multiple orders requiring REPs in the ERCOT market to suspend late fees
for residential customers through May 15, 2020, and to offer deferred payment
plans to customers upon request. The PUCT also enacted the COVID-19 Electricity
Relief Program whereby REPs must forego disconnecting customers certified as
experiencing COVID-19-related hardship, and if such customer would otherwise be
subject to disconnection and meets other qualifications, such REP would request
suppression of the delivery charges from the transmission and distribution
utility and request a proxy energy charge reimbursement from the COVID-19
Electricity Relief Program of $0.04/kWh. The PUCT ceased accepting new
enrollments under the COVID-19 Electricity Relief Program after August 31, 2020,
and the disconnection protections and financial assistance expired after
September 30, 2020.

See Note 7 to the Financial Statements for a summary of certain anticipated tax-related impacts of the CARES Act to the Company.

Ambit Transaction



On November 1, 2019 (Ambit Acquisition Date), Volt Asset Company, Inc., an
indirect, wholly owned subsidiary of Vistra, completed the acquisition of Ambit
(Ambit Transaction). See Note 2 to the Financial Statements for a summary of the
Ambit Transaction and business combination accounting.

Crius Transaction



On July 15, 2019, Vienna Acquisition B.C. Ltd., an indirect, wholly owned
subsidiary of Vistra, completed the acquisition of the equity interests of two
wholly owned subsidiaries of Crius that indirectly own the operating business of
Crius (Crius Transaction). See Note 2 to the Financial Statements for a summary
of the Crius Transaction and business combination accounting.

Dividend Program



In November 2018, we announced that the Board had adopted a dividend program,
which we initiated in the first quarter of 2019. See Note 13 to the Financial
Statements for more information about our dividend program.

Share Repurchase Program



In September 2020, we announced that the Board had authorized a new share
repurchase program (Share Repurchase Program) under which up to $1.5 billion of
our outstanding common stock may be repurchased. The Share Repurchase Program
will be effective January 1, 2021, at which time the Prior Share Repurchase Plan
will terminate. See Note 13 to the Financial Statements for more information
concerning the Share Repurchase Program and the Prior Share Repurchase Program,
including shares repurchased and remaining amounts available under the Prior
Share Repurchase Program.

Debt Activity

We have stated our objective to reduce our consolidated net leverage. We also
intend to continue to simplify and optimize our capital structure, maintain
adequate liquidity and pursue opportunities to refinance our long-term debt to
extend maturities and/or reduce ongoing interest expense. In 2019 and 2020, we
completed several transactions, including the redemption and repayment of all
previously outstanding senior notes issued by Parent, that we believe, in the
aggregate, advanced all of these goals. See Note 11 to the Financial Statements
for details of our long-term debt activity and Note 10 to the Financial
Statements for details of our accounts receivable financing.

Power Price, Natural Gas Price and Market Heat Rate Exposure

Estimated hedging levels for generation volumes in our Texas, East, West and Sunset segments at September 30, 2020 were as follows:

The following sensitivity table provides approximate estimates of the potential
impact of movements in power prices and spark spreads (the difference between
the power revenue and fuel expense of natural gas-fired generation as calculated
using an assumed heat rate of 7.2 MMBtu/MWh) on realized pretax earnings (in
millions) taking into account the hedge positions noted above for the periods
presented. The residual gas position is calculated based on two steps: first,
calculating the difference between actual heat rates of our natural gas
generation units and the assumed 7.2 heat rate used to calculate the sensitivity
to spark spreads; and second, calculating the residual natural gas exposure that
is not already included in the gas generation spark spread sensitivity shown in
the table below. The estimates related to price sensitivity are based on our
expected generation, related hedges and forward prices as of September 30, 2020.

Our operating segments delivered strong operating performance with a disciplined
focus on cost management, while generating and selling essential electricity in
a safe and reliable manner during a period of significant economic disruption.
Our performance reflected the stability of our integrated model, including a
diversified generation fleet, retail and commercial and hedging activities in
support of our integrated business, to produce results in line with expectations
and significant cash from operations of $1.041 billion in the three months ended
September 30, 2020 despite general uncertainty in the overall economy.
Consolidated results increased $328 million to net income of $442 million in the
three months ended September 30, 2020 compared to the three months ended
September 30, 2019. The change in results is driven by $321 million in pre-tax
unrealized net gains on hedging transactions in 2020 compared to $79 million in
pre-tax unrealized net losses on hedging transactions in 2019 and strong Texas
wholesale operating results, partially offset by a $272 million pre-tax
impairment of assets related to our Kincaid and Zimmer coal generation
facilities.

For the three months ended September 30, 2020 and 2019, operating costs increased $60 million to $457 million primarily driven by higher estimated costs for ARO.



For the three months ended September 30, 2020 and 2019, selling, general and
administrative expense increased by $22 million, primarily due to the increased
expense resulting from the acquisition of Crius in July 2019 and Ambit in
November 2019.

Interest expense and related charges decreased $123 million to $101 million in
the three months ended September 30, 2020 compared to the three months ended
September 30, 2019 driven by unrealized mark-to-market gains of $11 million in
2020 compared to unrealized mark-to-market losses of $76 million in 2019 and a
$27 million decrease in interest paid/accrued reflecting the reduction in higher
interest Vistra senior unsecured notes through the Redemptions and Tender Offers
in 2019 and 2020. See Note 18 to the Financial Statements.

For the three months ended September 30, 2020 and 2019, the Impacts of the Tax
Receivable Agreement totaled income of $58 million and expense of $62 million,
respectively. See Note 8 to the Financial Statements for discussion of the
impacts of the Tax Receivable Agreement Obligation.

Our operating segments delivered strong operating performance with a disciplined
focus on cost management, while generating and selling essential electricity in
a safe and reliable manner during a period of significant economic disruption.
Our performance reflected the stability of our integrated model, including a
diversified generation fleet, retail and commercial and hedging activities in
support of our integrated business, to produce results in line with expectations
and significant cash from operations of $2.350 billion for the nine months ended
September 30, 2020 despite general uncertainty in the overall economy.

Consolidated results decreased $41 million to net income of $651 million in the
nine months ended September 30, 2020 compared to the nine months ended
September 30, 2019. The change in results is driven by a $181 million pre-tax
decrease in unrealized gains on hedging transactions, a $356 million pre-tax
impairment of assets related to our Kincaid, Zimmer and Joppa/EEI coal
generation facilities and a $29 million pre-tax loss on disposal of our equity
method investment in Northeast Energy, LP (NELP), almost completely offset by
strong Texas wholesale operating results and the addition of Crius and Ambit.
See Note 18 to the Financial Statements.

For the nine months ended September 30, 2020 and 2019, operating costs increased
$96 million to $1,249 million primarily driven by higher estimated costs for
ARO, increased LTSA costs and COVID-related expenses.

For the nine months ended September 30, 2020 and 2019, selling, general and administrative expense increased by $118 million, primarily due to the increased expense resulting from the acquisition of Crius in July 2019 and Ambit in November 2019.



Interest expense and related charges decreased $179 million to $541 million in
the nine months ended September 30, 2020 compared to the nine months ended
September 30, 2019 driven by a $83 million decrease in interest paid/accrued
reflecting the reduction in higher interest Vistra senior unsecured notes
through the Redemptions and Tender Offers in 2019 and 2020 and a $94 million
decrease in unrealized mark-to-market losses on interest rate swaps. See Note 18
to the Financial Statements.

For the nine months ended September 30, 2020 and 2019, the Impacts of the Tax
Receivable Agreement totaled income of $44 million and expense of $26 million,
respectively. See Note 8 to the Financial Statements for discussion of the
impacts of the Tax Receivable Agreement Obligation.

Discussion of Adjusted EBITDA



Non-GAAP Measures - In analyzing and planning for our business, we supplement
our use of GAAP financial measures with non-GAAP financial measures, including
EBITDA and Adjusted EBITDA as performance measures. These non-GAAP financial
measures reflect an additional way of viewing aspects of our business that, when
viewed with our GAAP results and the accompanying reconciliations to
corresponding GAAP financial measures included in the tables below, may provide
a more complete understanding of factors and trends affecting our business.
These non-GAAP financial measures should not be relied upon to the exclusion of
GAAP financial measures and are, by definition, an incomplete understanding of
Vistra and must be considered in conjunction with GAAP measures. In addition,
non-GAAP financial measures are not standardized; therefore, it may not be
possible to compare these financial measures with other companies' non-GAAP
financial measures having the same or similar names. We strongly encourage
investors to review our consolidated financial statements and publicly filed
reports in their entirety and not rely on any single financial measure.

EBITDA and Adjusted EBITDA - We believe EBITDA and Adjusted EBITDA provide
meaningful representations of our operating performance. We consider EBITDA as
another way to measure financial performance on an ongoing basis. Adjusted
EBITDA is meant to reflect the operating performance of our segments for the
period presented. We define EBITDA as earnings (loss) before interest expense,
income tax expense (benefit) and depreciation and amortization expense. We
define Adjusted EBITDA as EBITDA adjusted to exclude (i) gains or losses on the
sale or retirement of certain assets, (ii) the impacts of mark-to-market changes
on derivatives, (iii) the impact of impairment charges, (iv) certain amounts
associated with fresh-start reporting, acquisitions, dispositions, transition
costs or restructurings, (v) non-cash compensation expense, (vi) impacts from
the Tax Receivable Agreement and (vii) other material nonrecurring or unusual
items.

Because EBITDA and Adjusted EBITDA are financial measures that management uses to allocate resources, determine our ability to fund capital expenditures, assess performance against our peers, and evaluate overall financial performance, we believe they provide useful information for investors.

When EBITDA or Adjusted EBITDA is discussed in reference to performance on a consolidated basis, the most directly comparable GAAP financial measure to EBITDA and Adjusted EBITDA is Net income (loss).

The change in Texas segment results was driven by improved realized margin through hedging activities and plant optimization efforts, and higher unrealized gains, partially offset by higher operating expenses and other costs.



The change in East segment results was driven by higher unrealized hedging gains
and improved realized margin through hedging activities and plant optimization
efforts, partially offset by lower capacity revenue and increased depreciation
expenses.

The change in West segment results was driven by lower unrealized gains.

The change in Sunset segment results was driven by impairment of assets related to our Kincaid and Zimmer coal generation facilities and related generation plant retirement expenses, partially offset by lower unrealized hedging losses.

The change in Texas segment results was driven by higher realized prices through
hedging activities and plant optimization efforts, partially offset by lower
unrealized hedging gains, lower insurance reimbursement and COVID-19 related
expenses in the current year.

The change in East segment results was driven by lower unrealized hedging gains,
lower capacity revenue, loss on disposal of equity method investment in NELP for
100% ownership of North Jersey Energy Associates (see Note 18 to the Financial
Statements) and COVID-19 related expenses in the current year.

The change in West segment results was driven by lower unrealized hedging gains,
partially offset by higher realized prices through hedging activities and plant
optimization efforts.

The change in Sunset segment results was driven by impairment of assets related
to our Kincaid, Zimmer and Joppa/EEI coal generation facilities and related
generation plant retirement expenses, higher unrealized hedging losses, lower
capacity revenue, and higher operating costs.

Results for the Asset Closure segment primarily reflect the retirement of the
Coffeen, Duck Creek, Havana and Hennepin plants in November and December 2019
(see Note 4 to the Financial Statements). Operating costs for the three and nine
months ended September 30, 2020 included ongoing costs associated with the
decommissioning and reclamation of retired plants and mines.

FINANCIAL CONDITION

Operating Cash Flows

Nine Months Ended September 30, 2020 Compared to Nine Months Ended September 30,
2019 - Cash provided by operating activities totaled $2.350 billion and $1.823
billion for the nine months ended September 30, 2020 and 2019, respectively. The
favorable change of $527 million was primarily driven by increased cash from
operations and a decrease in cash margin deposits posted with third-parties.

Depreciation and amortization expense reported as a reconciling adjustment in
the condensed consolidated statements of cash flows exceeds the amount reported
in the condensed consolidated statements of operations by $228 million and $181
million for the nine months ended September 30, 2020 and 2019, respectively. The
difference represented amortization of nuclear fuel, which is reported as fuel
costs in the condensed consolidated statements of operations consistent with
industry practice, and amortization of intangible net assets and liabilities
that are reported in various other condensed consolidated statements of
operations line items including operating revenues and fuel and purchased power
costs and delivery fees.

Investing Cash Flows

Cash used in investing activities totaled $927 million and $979 million for the
nine months ended September 30, 2020 and 2019, respectively. Capital
expenditures totaled $838 million and $474 million for the nine months ended
September 30, 2020 and 2019, respectively. Cash used in investing activities for
the nine months ended September 30, 2020 and 2019 also reflected net purchases
of environmental allowances of $119 million and $137 million, respectively. For
the nine months ended September 30, 2020 and 2019, capital expenditures
consisted of:

Financing Cash Flows

Cash used in financing activities totaled $1,348 million and $784 million for
the nine months ended September 30, 2020 and 2019, respectively. The change was
primarily driven by:

•issuance of $4.6 billion principal amount of Vistra Operations senior secured
and unsecured notes in 2019;
•redemption of $166 million principal amount of outstanding of 8.125% senior
notes in July 2020;
•redemption of $500 million principal amount of outstanding of 5.875% senior
notes in June 2020;
•net repayment of $350 million in short-term borrowings under the Revolving
Credit Facility in 2020;
•repayment of $100 million of term loans under the Vistra Operations Credit
Facility in March 2020, and
•redemption of $81 million principal amount of outstanding of 8.000% senior
notes in January 2020,

partially offset by:

•cash tender offers and early redemptions to purchase approximately $2.5 billion
of senior unsecured notes assumed in the Merger in 2019;
•repayment of approximately $2.0 billion of term loans under the Vistra
Operations Credit Facilities in 2019;
•$632 million in cash paid for share repurchases in 2019, and
•$153 million decrease in debt tender offer and other financing fees in 2020
compared to 2019.

1,726 $ 831





The $831 million increase in available liquidity for the nine months ended
September 30, 2020 was primarily driven by cash from operations, repayments of
cash borrowings under the Revolving Credit Facility and a reduction in letters
of credit outstanding under the Revolving Credit Facility reflecting the
issuance of $166 million of letters of credit under the new Secured LOC
Facilities, partially offset by $838 million of capital expenditures (including
LTSA prepayments, nuclear fuel and development and growth expenditures), $747
million principal amount of outstanding Vistra senior unsecured notes redeemed
in 2020, $100 million of term loans under the Vistra Operations Credit Facility
repaid in March 2020, $81 million principal amount of outstanding of 8.000%
senior notes redeemed in January 2020 and $198 million in dividends paid to
shareholders.

Based upon our current internal financial forecasts, we believe that we will
have sufficient liquidity to fund our anticipated cash requirements, including
those related to our capital allocation initiatives, through at least the next
12 months. Our operational cash flows tend to be seasonal and weighted toward
the second half of the year.

Liquidity Effects of Commodity Hedging and Trading Activities



We have entered into commodity hedging and trading transactions that require us
to post collateral if the forward price of the underlying commodity moves such
that the hedging or trading instrument we hold has declined in value. We use
cash, letters of credit and other forms of credit support to satisfy such
collateral posting obligations. See Note 11 to the Financial Statements for
discussion of the Vistra Operations Credit Facilities.

Exchange cleared transactions typically require initial margin (i.e., the
upfront cash and/or letter of credit posted to take into account the size and
maturity of the positions and credit quality) in addition to variation margin
(i.e., the daily cash margin posted to take into account changes in the value of
the underlying commodity). The amount of initial margin required is generally
defined by exchange rules. Clearing agents, however, typically have the right to
request additional initial margin based on various factors, including market
depth, volatility and credit quality, which may be in the form of cash, letters
of credit, a guaranty or other forms as negotiated with the clearing agent. Cash
collateral received from counterparties is either used for working capital and
other business purposes, including reducing borrowings under credit facilities,
or is required to be deposited in a separate account and restricted from being
used for working capital and other corporate purposes. With respect to
over-the-counter transactions, counterparties generally have the right to
substitute letters of credit for such cash collateral. In such event, the cash
collateral previously posted would be returned to such counterparties, which
would reduce liquidity in the event the cash was not restricted.

At September 30, 2020, we received or posted cash and letters of credit for commodity hedging and trading activities as follows:



•$155 million in cash has been posted with counterparties as compared to $202
million posted at December 31, 2019;
•$11 million in cash has been received from counterparties as compared to $8
million received at December 31, 2019;
•$1.034 billion in letters of credit have been posted with counterparties as
compared to $1.150 billion posted at December 31, 2019, and
•$20 million in letters of credit have been received from counterparties as
compared to $17 million received at December 31, 2019.

Income Tax Payments



In the next 12 months, we do not expect to make federal income tax payments due
to Vistra's use of NOL carryforwards. We expect to make approximately $35
million in state income tax payments, offset by $11 million in state tax
refunds, and no TRA payments in the next 12 months. In addition, we expect to
receive approximately $129 million in AMT refundable credits in the next 12
months.

For the nine months ended September 30, 2020, we received a refund of $37
million related to alternative minimum tax credits claimed on Dynegy tax
returns. For the nine months ended September 30, 2020, there were no federal
income tax payments, $32 million in state income tax payments, $6 million in
state income tax refunds and no TRA payments.

Financial Covenants



The Credit Facilities Agreement includes a covenant, solely with respect to the
Revolving Credit Facility and solely during a compliance period (which, in
general, is applicable when the aggregate revolving borrowings and issued
revolving letters of credit (in excess of $300 million) exceed 30% of the
revolving commitments), that requires the consolidated first-lien net leverage
ratio not exceed 4.25 to 1.00. Although the period ended September 30, 2020 was
not a compliance period, we would have been in compliance with this financial
covenant if it was required to be tested at such date.

See Note 11 to the Financial Statements for discussion of other covenants related to the Vistra Operations Credit Facilities.

Collateral Support Obligations



The RCT has rules in place to assure that parties can meet their mining
reclamation obligations. In September 2016, the RCT agreed to a collateral bond
of up to $975 million to support Luminant's reclamation obligations. The
collateral bond is effectively a first lien on all of Vistra Operations' assets
(which ranks pari passu with the Vistra Operations Credit Facilities) that
contractually enables the RCT to be paid (up to $975 million) before the other
first-lien lenders in the event of a liquidation of our assets. Collateral
support relates to land mined or being mined and not yet reclaimed as well as
land for which permits have been obtained but mining activities have not yet
begun and land already reclaimed but not released from regulatory obligations by
the RCT, and includes cost contingency amounts.

The PUCT has rules in place to assure adequate creditworthiness of each REP,
including the ability to return customer deposits, if necessary. Under these
rules, at September 30, 2020, Vistra has posted letters of credit in the amount
of $98 million with the PUCT, which is subject to adjustments.

The ISOs/RTOs we operate in have rules in place to assure adequate
creditworthiness of parties that participate in the markets operated by those
ISOs/RTOs. Under these rules, Vistra has posted collateral support totaling $351
million in the form of letters of credit, $10 million in the form of a surety
bond and $2 million of cash at September 30, 2020 (which is subject to daily
adjustments based on settlement activity with the ISOs/RTOs).

Material Cross Default/Acceleration Provisions



Certain of our contractual arrangements contain provisions that could result in
an event of default if there was a failure under financing arrangements to meet
payment terms or to observe covenants that could result in an acceleration of
payments due. Such provisions are referred to as "cross default" or "cross
acceleration" provisions.

A default by Vistra Operations or any of its restricted subsidiaries in respect
of certain specified indebtedness in an aggregate amount in excess of $300
million may result in a cross default under the Vistra Operations Credit
Facilities. Such a default would allow the lenders to accelerate the maturity of
outstanding balances (approximately $2.6 billion at September 30, 2020) under
such facilities.

Each of Vistra Operations' (or its subsidiaries') commodity hedging agreements
and interest rate swap agreements that are secured with a lien on its assets on
a pari passu basis with the Vistra Operations Credit Facilities lenders contains
a cross default provision. An event of a default by Vistra Operations or any of
its subsidiaries relating to indebtedness equal to or above a threshold defined
in the applicable agreement that results in the acceleration of such debt, would
give such counterparty under these hedging agreements the right to terminate its
hedge or interest rate swap agreement with Vistra Operations (or its applicable
subsidiary) and require all outstanding obligations under such agreement to be
settled.

Under (i) the Vistra Operations Senior Unsecured Indentures and the Vistra
Operations Senior Secured Indenture, a default under any document evidencing
indebtedness for borrowed money by Vistra Operations or any Guarantor Subsidiary
for failure to pay principal when due at final maturity or that results in the
acceleration of such indebtedness in an aggregate amount of $300 million or more
may have resulted in a cross default under the Vistra Operations Senior
Unsecured Notes, the Senior Secured Notes, the Vistra Operations Credit
Facilities, the Receivables Facility, the Alternate LOC Facilities, and other
current or future documents evidencing any indebtedness for borrowed money by
the applicable borrower or issuer, as the case may be, and the applicable
Guarantor Subsidiaries party thereto.

Additionally, we enter into energy-related physical and financial contracts, the
master forms of which contain provisions whereby an event of default or
acceleration of settlement would occur if we were to default under an obligation
in respect of borrowings in excess of thresholds, which may vary by contract.

The Receivables Facility contains a cross-default provision. The cross default
provision applies, among other instances, if Vistra Operations, the performance
guarantor, fails to make a payment of principal or interest on any indebtedness
that is outstanding in a principal amount of at least $300 million, or, in the
case of TXU Energy, the originator and servicer, in a principal amount of at
least $50 million, or if other events occur or circumstances exist under such
indebtedness which give rise to a right of the debtholder to accelerate such
indebtedness, or if such indebtedness becomes due before its stated maturity. If
this cross-default provision is triggered, a termination event under the
Receivables Facility would occur and the Receivables Facility may be terminated.

The Repurchase Facility contains a cross-default provision. The cross-default
provision applies, among other instances, if an event of default (or similar
event) occurs under the Receivables Facility or the Vistra Operations Credit
Facilities. If this cross-default provision is triggered, a termination event
under the Repurchase Facility would occur and the Repurchase Facility may be
terminated.

Under the Alternate LOC Facilities, a default under any document evidencing
indebtedness for borrowed money by Vistra Operations or any Guarantor Subsidiary
for failure to pay principal when due at final maturity or that results in the
acceleration of such indebtedness in an aggregate amount of $300 million or
more, may result in a termination of the Alternate LOC Facilities.

Under the Secured LOC Facilities, a default under any document evidencing
indebtedness for borrowed money by Vistra Operations or any Guarantor Subsidiary
for failure to pay principal when due at final maturity or that results in the
acceleration of such indebtedness in an aggregate amount of $300 million or
more, may result in a termination of the Secured LOC Facilities.

Guarantor Summary Financial Information



During the three months ended September 30, 2020, our 8.125% senior notes were
guaranteed by substantially all of our wholly owned subsidiaries. We fully
redeemed the 8.125% senior notes on in July 2020. The following tables summarize
the combined financial information of (i) Vistra Corp. (Parent), which is the
ultimate parent company and issuer of the senior notes with effect as of the
Merger Date, on a stand-alone, unconsolidated basis and (ii) the guarantor
subsidiaries of Vistra (Guarantor Subsidiaries). The Guarantor Subsidiaries
consist of the wholly owned subsidiaries, which jointly, severally, fully and
unconditionally, guarantee the payment obligations under the senior notes. See
Note 11 to the Financial Statements for discussion of the senior notes and Note
13 to the Financial Statements for discussion of dividend restrictions of Vistra
Operations (a guarantor subsidiary of Vistra) and Parent.

This financial information should be read in conjunction with the unaudited
condensed consolidated financial statements and notes thereto of Vistra.
Transactions between the Parent and the Guarantor Subsidiaries have been
eliminated. The inclusion of Vistra's subsidiaries as Guarantor Subsidiaries in
the summary financial information is determined as of the most recent balance
sheet date presented.
