The following discussion should be read in conjunction with the financial
statements contained in this Form 10-Q, as well as Management's Discussion and
Analysis of Financial Condition and Results of Operations and Risk Factors
contained in the Form 10-K. We intend for this discussion to provide the reader
with information that will assist in understanding our financial statements, the
changes in certain key items in those financial statements, and the primary
factors that accounted for those changes, as well as how certain accounting
principles affect our financial statements. The discussion also provides
information about the financial results of our business segments to provide a
better understanding of how those segments and their results affect the
financial condition and results of operations of Ameren as a whole. Also see the
Glossary of Terms and Abbreviations at the front of this report and in the Form
10-K.

Ameren, headquartered in St. Louis, Missouri, is a public utility holding company whose primary assets are its equity interests in its subsidiaries. Ameren's subsidiaries are separate, independent legal entities with separate businesses, assets, and liabilities. Dividends on

Ameren's common stock and the payment of expenses by Ameren depend on
distributions made to it by its subsidiaries. Ameren's principal subsidiaries
are listed below. Ameren has other subsidiaries that conduct other activities,
such as providing shared services.

•Union Electric Company, doing business as Ameren Missouri, operates a
rate-regulated electric generation, transmission, and distribution business and
a rate-regulated natural gas distribution business in Missouri.
•Ameren Illinois Company, doing business as Ameren Illinois, operates
rate-regulated electric transmission, electric distribution, and natural gas
distribution businesses in Illinois.
•ATXI operates a FERC rate-regulated electric transmission business in the MISO.

Ameren's and Ameren Missouri's financial statements are prepared on a
consolidated basis and therefore include the accounts of their majority-owned
subsidiaries. All intercompany transactions have been eliminated. Ameren
Missouri's subsidiaries were created for the ownership of renewable generation
projects. Ameren Illinois has no subsidiaries. All tabular dollar amounts are in
millions, unless otherwise indicated.

In addition to presenting results of operations and earnings amounts in total,
we present certain information in cents per share. These amounts reflect factors
that directly affect Ameren's earnings. We believe this per share information
helps readers to understand the impact of these factors on Ameren's earnings per
share.

OVERVIEW

Net income attributable to Ameren common shareholders was $207 million, or $0.80
per diluted share, in both the three months ended June 30, 2022 and 2021. Net
income attributable to Ameren common shareholders in the six months ended
June 30, 2022, was $459 million, or $1.77 per diluted share, compared with $440
million, or $1.71 per diluted share, in the year-ago period. Net income for the
three and six months ended June 30, 2022, was favorably affected by increased
rate base investments across all segments and a higher recognized ROE at Ameren
Illinois Electric Distribution and increased retail electric sales volumes at
Ameren Missouri, primarily resulting from colder winter and warmer early summer
temperatures experienced in 2022. Net income for the three and six months ended
June 30, 2022, compared with the year-ago periods, were unfavorably affected by
increased other operations and maintenance expenses not subject to formula
rates, riders, or trackers, primarily due to a reduction in the cash surrender
value of company-owned life insurance, higher transmission and distribution
expenses due to the timing of expenses and disciplined project management, and
an increase due to the expiration of contracts relating to refined coal tax
credits at Ameren Missouri in 2021. Net income comparisons in both periods were
also unfavorably affected by increased financing costs from debt issuances.
Earnings per share comparisons in both periods were unfavorably affected by an
increase in the weighted-average basic common shares outstanding.

Ameren's strategic plan includes investing and operating its utilities in a
manner consistent with existing regulatory frameworks, enhancing those
frameworks, and advocating for responsible energy and economic policies, as well
as creating and capitalizing on opportunities for investment for the benefit of
its customers, shareholders, and the environment. Ameren remains focused on
disciplined cost management and strategic capital allocation. Ameren invested
$1.5 billion in its rate-regulated businesses in the six months ended June 30,
2022.

The COVID-19 pandemic continues to affect our results of operations, financial
position, and liquidity. While our electric sales volumes, excluding the
estimated effects of weather and customer energy-efficiency programs, increased
in the first six months of 2022, compared to the same period in 2021, they were
comparable to pre-pandemic levels at Ameren Missouri and remain below
pre-pandemic levels at Ameren Illinois. However, revenues from Ameren Illinois'
electric distribution business, residential and small nonresidential customers
of Ameren Illinois' natural gas distribution business, and Ameren Illinois' and
ATXI's electric transmission businesses are decoupled from changes in sales
volumes. Earnings at Ameren Missouri and those associated with Ameren Illinois'
large nonresidential natural gas customers are exposed to such changes. There
has also been a shift in sales volumes by customer class at both Ameren Missouri
and Ameren Illinois, which began in 2020, with an increase in residential sales,
and a decrease in commercial and industrial sales. The continued effect of the
COVID-19 pandemic on our results of operations, financial position, and
liquidity in subsequent periods will depend on its severity and longevity,
future regulatory or legislative actions with respect thereto, and the resulting
impact on business, economic, and capital market conditions. We continue to
assess the impacts the COVID-19 pandemic is having on our businesses, including
impacts on electric and natural gas sales volumes, liquidity, bad debt expense,
and supply chain operations. For further discussion of these and other matters
discussed below, see Note 1 - Summary of Significant Accounting Policies and
Note 2 - Rate and Regulatory Matters under Part I, Item 1, of this report, and
Results of Operations, Liquidity and Capital Resources, and Outlook sections
below.

In December 2021, Ameren Missouri filed a motion with the United States District
Court for the Eastern District of Missouri to modify a September 2019 remedy
order issued by the district court to allow the retirement of the Rush Island
Energy Center in advance of its previously expected useful life in lieu of
installing a flue gas desulfurization system. In June 2022, Ameren Missouri
supplemented its filing with the district court by proposing reduced operations,
mostly operating during peak demand times and emergencies until the energy
center is retired. The March 31, 2024 compliance date contained in the district
court's September 2019 remedy order remains in effect unless extended by the
district court. In July 2022, in response to an Ameren Missouri request for a
final, binding reliability assessment, the MISO
                                       41

designated the Rush Island Energy Center as a system support resource and
concluded that certain mitigation measures, including transmission upgrades,
should occur before the energy center is retired. The transmission upgrade
projects have been approved by the MISO, and Ameren Missouri has started design
and procurement activities necessary to complete the upgrades and expects to
complete the upgrades by late 2025. The FERC will need to approve a system
support resource agreement detailing the manner of continued operation of the
Rush Island Energy Center, as well as a request from Ameren Missouri for
recovery of non-energy costs under the related MISO tariff. The agreement, if
approved, would have a term of 12 months. The system support resource
designation and the related agreement are subject to renewal and revision. Any
difference between revenues and costs under the MISO tariff is expected to be
included in the FAC. The district court has the authority to determine the
retirement date and operating parameters for the Rush Island Energy Center and
is not bound by the MISO determination of the Rush Island Energy Center as a
system support resource or the FERC's approval. While the district court is
under no deadline to issue a ruling modifying the remedy order, a decision is
expected in the near term. Related to this matter, in February 2022, the MoPSC
issued an order directing the MoPSC staff to review Ameren Missouri's planned
accelerated retirement of the Rush Island Energy Center, including potential
impacts on the reliability and cost of Ameren Missouri's service to its
customers; Ameren Missouri's plans to mitigate the customer impacts of the
accelerated retirement; and the prudence of Ameren Missouri's actions and
decisions with regard to the Rush Island Energy Center, which is expected to be
addressed in the current electric service regulatory rate review, among other
things. In April 2022, the MoPSC staff filed an initial report with the MoPSC in
which the staff concluded early retirement of the Rush Island Energy Center may
cause reliability concerns. The MoPSC staff is under no deadline to complete
this review. Ameren Missouri expects to seek approval from the MoPSC to finance
the costs associated with the retirement, including the remaining unrecovered
net plant balance associated with the facility, through the issuance of
securitized utility tariff bonds pursuant to the Missouri securitization
statute. See Note 9 - Commitments and Contingencies under Part I, Item 1, of
this report for additional information.

In February 2022, Ameren Missouri filed an update to its Smart Energy Plan with
the MoPSC, which includes a five-year capital investment overview with a
detailed one-year plan for 2022. The plan is designed to upgrade Ameren
Missouri's electric infrastructure and includes investments that will upgrade
the grid and accommodate more renewable energy. Investments under the plan are
expected to total approximately $8.4 billion over the five-year period from 2022
through 2026, with expenditures largely recoverable under the PISA and the
RESRAM.

In February 2022, Ameren Missouri, through a subsidiary, entered into a
build-transfer agreement to acquire, after construction, a 150-MW solar
generation facility, which is expected to be located in southeastern Illinois
and, if approved by the MoPSC, serve customers under Ameren Missouri's Renewable
Solutions Program. In June 2022, Ameren Missouri, through a subsidiary, entered
into a build-transfer agreement to acquire, after construction, a 200-MW solar
generation facility, which is expected to be located in central Missouri and
support Ameren Missouri's compliance with the state of Missouri's requirement of
achieving 15% of retail sales from renewable energy sources, of which 2% must be
derived from solar energy sources. The acquisitions are aligned with the 2022
Change to the 2020 IRP, which Ameren Missouri filed with the MoPSC in June 2022,
and are subject to certain conditions, including the issuance of certificates of
convenience and necessity by the MoPSC, obtaining MISO transmission
interconnection agreements, and approval by the FERC. In July 2022, Ameren
Missouri filed for certificates of convenience and necessity with the MoPSC for
both facilities and expects decisions by March 2023 and April 2023 for the
200-MW facility and the 150-MW facility, respectively. Depending on the timing
of regulatory approvals and the impact of potential sourcing issues resulting
from a Department of Commerce investigation of solar panels imported from four
Southeast Asian countries initiated in late March 2022 and the detention of
certain solar panels sourced from China as a result of the Uyghur Forced Labor
Prevention Act that was passed in December 2021, the projects could be completed
as early as the fourth quarter of 2024.

In June 2022, Missouri Senate Bill 745 was enacted and will become effective on
August 28, 2022. The law extended Ameren Missouri's PISA election through
December 2028 and allows for an additional five-year extension through December
2033 if requested by Ameren Missouri and approved by the MoPSC, among other
things. The law established a 2.5% annual limit on increases to the electric
service revenue requirement used to set customer rates due to the inclusion of
incremental PISA deferrals in the revenue requirement. The limitation will be
effective for revenue requirements approved by the MoPSC after January 1, 2024,
and will be based on the revenue requirement established in the immediately
preceding rate order. The current rate limitation, which is effective through
2023, is a 2.85% cap on the compound annual growth rate in the average overall
customer rate per kilowatthour, based on the electric rates that became
effective in April 2017, less half of the annual savings from the TCJA that was
passed on to customers as approved in a July 2018 MoPSC order. The law also
established electric and natural gas property tax trackers that allow Ameren
Missouri to defer the difference between actual property taxes incurred and
related taxes included in customer rates as a regulatory asset or regulatory
liability, with the difference expected to be reflected in rate base in a
subsequent rate order.

In August 2022, Ameren Missouri filed a request with the MoPSC seeking approval
to increase its annual revenues for electric service by $316 million. The
electric rate increase request is based on a 10.2% ROE, a capital structure
composed of 51.9% common equity, a rate base of $11.6 billion, and a test year
ended March 31, 2022, with certain pro-forma adjustments expected through an
anticipated true-up date of December 31, 2022. The MoPSC proceeding relating to
the proposed electric service rate changes will take place over a period of up
to 11 months, with a decision by the MoPSC expected by June 2023 and new rates
effective by July 2023.

In January 2022, Ameren Illinois filed a request with the ICC proposing
performance metrics that would be used in determining ROE incentives and
penalties under an MYRP. In April 2022, Ameren Illinois filed a revised request
proposing total ROE incentives and penalties of 24 basis points, allocated
evenly among eight proposed performance metrics. In May 2022, the ICC staff
recommended that the ICC allow ROE incentives and penalties of no less than 20
basis points and no more than 24 basis points, allocated evenly across the
number of performance metrics ultimately approved by the ICC. The ICC is
required to issue an order on this matter by September 30, 2022.

In April 2022, Ameren Illinois filed its annual electric distribution service
performance-based formula rate update with the ICC to be used for 2023 rates. In
July 2022, Ameren Illinois filed a revised request seeking to increase its
annual revenues for electric distribution service by $84 million. In June 2022,
the ICC staff submitted its calculation of the revenue requirement included in
Ameren Illinois' update filing, recommending a $60 million increase in Ameren
Illinois' electric distribution service rates. An ICC decision in this
proceeding is required by December 2022, with new rates effective in January
2023.

In June 2022, Ameren Illinois filed its annual electric customer
energy-efficiency formula rate update to increase its rates by $17 million with
the ICC. An ICC decision in this proceeding is required by December 2022, with
new rates effective January 2023.

In June 2022, the ICC issued an order approving Ameren Illinois' revised
energy-efficiency plan that includes annual investments in electric
energy-efficiency programs of approximately $120 million per year through 2025,
which reflects the increased level of annual investments allowed under the IETL.
The ICC has the ability to reduce the amount of electric energy-efficiency
savings goals in future plan program years if there are insufficient
cost-effective programs available, which could reduce the investments in
electric energy-efficiency programs. The electric energy-efficiency program
investments and the return on those investments are collected from customers
through a rider and are not recovered through the electric distribution service
performance-based formula ratemaking framework.

RESULTS OF OPERATIONS



Our results of operations and financial position are affected by many factors.
Economic conditions, including those resulting from the COVID-19 pandemic
discussed below, energy-efficiency investments by our customers and by us,
technological advances, distributed generation, and the actions of key customers
can significantly affect the demand for our services. Ameren and Ameren Missouri
results are also affected by seasonal fluctuations in winter heating and summer
cooling demands, as well as by energy center maintenance outages. Additionally,
fluctuations in interest rates and conditions in the capital and credit markets
affect our cost of borrowing, our pension and postretirement benefits costs, and
the cash surrender value of company-owned life insurance. Almost all of Ameren's
revenues are subject to state or federal regulation. This regulation has a
material impact on the rates we charge customers for our services. Our results
of operations, financial position, and liquidity are affected by our ability to
align our overall spending, both operating and capital, with the frameworks
established by our regulators. See Note 2 - Rate and Regulatory Matters under
Part I, Item 1, of this report and Note 2 - Rate and Regulatory Matters under
Part II, Item 8, of the Form 10-K for additional information regarding Ameren
Missouri's, Ameren Illinois', and ATXI's regulatory mechanisms.

We continue to monitor the impacts of the COVID-19 pandemic on our businesses,
including impacts on electric and natural gas sales volumes, liquidity, supply
chain operations, and bad debt expense. Regarding uncollectible accounts
receivable, Ameren Illinois' electric distribution and natural gas distribution
businesses have bad debt riders, which provide for recovery of bad debt
write-offs, net of any subsequent recoveries. Ameren Missouri does not have a
bad debt rider or tracker, and thus its earnings are exposed to increases in bad
debt expense, absent regulatory relief. However, Ameren Missouri has not
experienced and does not expect a material impact to earnings from increases in
bad debt expense.

Ameren Missouri principally uses coal and enriched uranium for fuel in its
electric operations and purchases natural gas for its customers. Ameren Illinois
purchases power and natural gas for its customers. The prices for these
commodities can fluctuate significantly because of the global economic and
political environment, weather, supply, demand, and many other factors. We have
natural gas cost recovery mechanisms for our Illinois and Missouri natural gas
distribution businesses, a purchased power cost recovery mechanism for Ameren
Illinois' electric distribution business, and a FAC for Ameren Missouri's
electric business.

We employ various risk management strategies to reduce our exposure to commodity
risk and other risks inherent in our business. The reliability of Ameren
Missouri's energy centers and our transmission and distribution systems, and the
level and timing of operations and maintenance costs and capital investment, are
key factors that we seek to manage in order to optimize our results of
operations, financial position, and liquidity.

Earnings Summary

The following table presents a summary of Ameren's earnings for the three and six months ended June 30, 2022 and 2021:



                                                             Three Months

Net income attributable to Ameren common shareholders    $   207      $ 207      $ 459      $ 440
Earnings per common share - diluted                         0.80       0.80 

1.77 1.71




Net income attributable to Ameren common shareholders was comparable between the
three months ended June 30, 2022, and the same period in 2021. Net income
increased $10 million and $8 million at Ameren Illinois Electric Distribution
and Ameren Transmission, respectively. The net income increases were offset by
net income decreases of $11 million and $2 million at Ameren Missouri and Ameren
Illinois Natural Gas, respectively, and an increase in net loss of $5 million
for activity not reported as part of a segment, primarily at Ameren (parent).

Net income attributable to Ameren common shareholders increased $19 million, or
6 cents per diluted share, in the six months ended June 30, 2022, compared with
the year-ago period. The increase was due to net income increases of
$19 million, $13 million, and $3 million at Ameren Transmission, Ameren Illinois
Electric Distribution, and Ameren Illinois Natural Gas, respectively. These
increases were partially offset by an $8 million decrease in net income at
Ameren Missouri and an $8 million decrease in the net income for activity not
reported as part of a segment, primarily at Ameren (parent).

Earnings per diluted share were favorably affected in the three and six months
ended June 30, 2022, compared to the year-ago periods (except where a specific
period is referenced), by:

•increased rate base investments at Ameren Transmission and Ameren Illinois
Electric Distribution and a higher recognized ROE due to a higher estimated
annual average of the monthly yields of the 30-year United States Treasury bonds
at Ameren Illinois Electric Distribution, which increased revenues at these
segments (6 cents and 10 cents per share, respectively);
•increased electric retail sales at Ameren Missouri, primarily resulting from
colder winter temperatures and warmer early summer temperatures experienced in
2022 (estimated at 5 cents and 8 cents per share, respectively);
•increased base rate revenues for the inclusion of previously deferred interest
charges pursuant to the December 2021 MoPSC electric rate order, partially
offset by lower deferral of interest charges related to infrastructure
investments associated with the PISA and RESRAM (2 cents and 5 cents per share,
respectively);
•increased Ameren Illinois Natural Gas earnings from investments in qualifying
infrastructure recovered under the QIP and higher base rates pursuant to the
ICC's January 2021 natural gas rate order (1 cent and 4 cents per share,
respectively);
•increased other income, net, primarily due to increased non-service cost
components of net periodic benefit income not subject to formula rates or
trackers (2 cents per share for the six months ended June 30, 2022);
•the absence in 2022 of the FERC's March 2021 order, primarily related to the
historical recovery of materials and supplies inventories, which decreased
Ameren Transmission revenues in 2021 (3 cents per share for the six months ended
June 30, 2022); and
•higher base rates at Ameren Missouri pursuant to the December 2021 MoPSC
electric rate order, partially offset by the amortization of previously deferred
depreciation expense under the PISA and RESRAM, financing costs otherwise
recoverable under the PISA and RESRAM, a higher base level of expenses, and the
net recovery for amounts associated with the reduction in sales volumes
resulting from MEEIA programs (2 cents per share for both periods).

Earnings per diluted share were unfavorably affected in the three and six months ended June 30, 2022, compared to the year-ago periods, by:



•increased other operations and maintenance expenses not subject to formula
rates, riders, or trackers, primarily due to a reduction in the cash surrender
value of company-owned life insurance, higher transmission and distribution
expenses due to the timing of expenses and disciplined project management, and
an increase due to the expiration of contracts relating to refined coal tax
credits at Ameren Missouri in 2021 (13 cents and 21 cents per share,
respectively);
•increased financing costs, primarily at Ameren (parent) and Ameren Missouri,
largely due to higher long-term debt balances (4 cents and 6 cents per share,
respectively); and
•increased weighted-average basic common shares outstanding resulting from
issuances of common shares as detailed in Note 4 - Long-term Debt and Equity
Financings under Part I, Item 1, of this report, and Note 5 - Long Term Debt and
Equity Financings under Part II, Item 8, of the Form 10-K (1 cent and 2 cents
per share, respectively).

The cents per share variances above are presented based on the weighted-average
basic common shares outstanding in the three and six months ended June 30, 2021,
and do not reflect the impact of dilution on earnings per share, unless
otherwise noted. The amounts above other than variances related to income taxes
have been presented net of income taxes using Ameren's 2022 blended federal and
state

Electric and Natural Gas Margins



Electric margins are defined as electric revenues less fuel and purchased power
costs. Natural gas margins are defined as natural gas revenues less natural gas
purchased for resale. We consider electric and natural gas margins useful
measures to analyze the change in profitability of our electric and natural gas
operations between periods. We have included the analysis below to complement
the financial information we provide in accordance with GAAP. However, these
margins may not be a presentation defined under GAAP, and they may not be
comparable to other companies' presentations or more useful than the GAAP
information we provide elsewhere in this report.

(c)For Ameren Illinois Electric Distribution and Ameren Transmission, base rates
include increases or decreases to operating revenues related to the revenue
requirement reconciliation adjustment under formula rates. For Ameren Missouri,
base rates exclude an increase for the recovery of lost electric margins
resulting from the MEEIA customer energy-efficiency programs and an increase in
base rates for RESRAM. These changes in Ameren Missouri base rates are included
in the "Sales volumes and changes in customer usage patterns (excluding the
estimated effects of weather and MEEIA)" and "Cost recovery mechanisms - offset
in fuel and purchased power" line items, respectively.
(d)Electric and natural gas revenue changes are offset by corresponding changes
in "Fuel," "Purchased power," and "Natural gas purchased for resale" on the
statement of income, resulting in no change to electric and natural gas margins.
Activity in Other/Intersegment Eliminations represents the elimination of
related-party transactions between Ameren Missouri, Ameren Illinois, and ATXI,
as well as Ameren Transmission revenue from transmission services provided to
Ameren Illinois Electric Distribution. See Note 8 - Related-party Transactions
and Note 14 - Segment Information under Part I, Item 1, of this report for
additional information on intersegment eliminations.
(e)Offsetting expense increases or decreases are reflected in "Other operations

Ameren

Ameren's electric margins increased $130 million, or 13%, and $195 million, or
10%, for the three and six months ended June 30, 2022, respectively, compared
with the year-ago periods, due to increased margins at Ameren Missouri, Ameren
Illinois Electric Distribution, and Ameren Transmission, as discussed below.
Ameren's natural gas margins increased $10 million, or 8%, and $33 million, or
9%, for the three and six months ended June 30, 2022, respectively, compared
with the year-ago periods, due to increased margins at Ameren Illinois Natural
Gas and Ameren Missouri, as discussed below.

Ameren Transmission

Ameren Transmission's margins increased $14 million, or 10%, and $30 million, or
11%, for the three and six months ended June 30, 2022, respectively, compared
with the year-ago periods. Base rate revenues were favorably affected by
increased capital investment (+$5 million and +$10 million, respectively), as
evidenced by a 10% increase in rate base used to calculate the revenue
requirement, as well as higher recoverable expenses (+$9 million and +$13
million, respectively), and the absence in 2022 of the FERC's March 2021 order
(+$7 million) for the six months ended June 30, 2022. See Transmission Formula
Rate Revisions in Note 2 - Rate and Regulatory Matters under Part I, Item 1, of
this report for additional information regarding the March 2021 FERC order.

Ameren Missouri



Ameren Missouri's electric margins increased $80 million, or 14%, and $104
million, or 10%, for the three and six months ended June 30, 2022, respectively,
compared with the year-ago periods. Revenues associated with "Cost recovery
mechanisms - offset in fuel and purchased power" increased $4 million and $28
million, respectively, for the three and six months ended June 30, 2022. The
increased revenues are fully offset by an increase in fuel and purchased power
costs, which increased primarily due to 2022 amortization of costs previously
deferred under the FAC that were reflected in customer rates. The changes to
"Cost recovery mechanisms - offset in fuel and purchased power" are fully offset
by "Cost recovery mechanisms - offset in electric revenue," in the table above,
and result in no impact to margins. Ameren Missouri's 5% exposure to net energy
cost variances under the FAC is reflected within "Off-system sales, capacity,
and FAC revenues, net" and "Energy costs (excluding the estimated effect of
weather)".

The following items had a favorable effect on Ameren Missouri's electric margins
for the three and six months ended June 30, 2022, compared with the year-ago
periods (except where a specific period is referenced):

•The December 2021 MoPSC electric rate order effective February 28, 2022, that
resulted in higher electric base rates, excluding the change in base rates for
the MEEIA customer energy efficiency programs and the RESRAM, partially offset
by higher net energy costs included in base rates, increased margins $56 million
and $74 million, respectively. The change in electric base rates is the sum of
the change in "Base rates (estimate)" (+$59 million and +$77 million,
respectively) and the "Effect of higher net energy costs included in base rates"
(-$3 million and -$3 million, respectively) in the table above.
•Summer temperatures were warmer as cooling degree days increased 12% for the
three months ended June 30, 2022, and winter temperatures were colder as heating
degree days increased 1% for the three months ended March 31, 2022. The
aggregate effect of weather increased margins an estimated $17 million and $23
million, respectively. The change in margins due to weather is the sum of the
"Effect of weather (estimate)" on electric revenues (+$21 million and +$28
million, respectively) and the "Effect of weather (estimate)" on fuel and
purchased power (-$4 million and -$5 million, respectively) in the table above.
•Other cost recovery mechanisms increased margins $13 million and $6 million,
respectively, due to increased RESRAM revenues (+$8 million and +$12 million,
respectively) primarily resulting from higher off-system sales recoverable under
the RESRAM, increased excise taxes (+$4 million and +$6 million, respectively),
and a change in recoverable MEEIA program costs (+$1 million and -$12 million,
respectively).
•Excluding the estimated effects of weather and the MEEIA customer
energy-efficiency programs, electric revenues increased an estimated $4 million
for the six months ended June 30, 2022. The increase was primarily due to an
increase in retail sales volumes, partially offset by a decrease in the average
retail price per kilowatthour due to changes in customer usage patterns.

Ameren Missouri's electric margins decreased $6 million and $1 million due to
Ameren Missouri's 5% exposure to net energy cost variances under the FAC for the
three and six months ended June 30, 2022, respectively. Net energy costs were
higher than those reflected in base rates, primarily because of higher purchased
power costs due to higher energy prices and the absence of electric revenues
from insurance recoveries related to the Callaway Energy Center maintenance
outage in 2021 in both periods, partially offset in the six months ended June
30, 2022, by an increase in off-system sales revenue due to higher energy prices
and increased generation from the Callaway Energy Center. In the three and six
months ended June 30, 2022, higher capacity revenues were almost entirely offset
by higher capacity costs included in "Purchased power" on Ameren's and Ameren
Missouri's consolidated income statements, with the increase in both revenues
and expenses caused by the capacity prices set in the April 2022 MISO capacity
auction, which became effective in June 2022. See Outlook for additional
information related to the April 2022 MISO capacity auction. The change in net
energy costs is the sum of "Off-system sales, capacity and FAC revenues, net"
(+$2 million and +$54 million, respectively) and "Energy costs (excluding the
estimated effect of weather)" (-$8 million and -$55 million, respectively) in
the table above.

Table of Contents



Ameren Missouri's natural gas margins increased $2 million, or 13%, and $4
million, or 9%, for the three and six months ended June 30, 2022, respectively,
compared with the year-ago periods, primarily due to increased base rates as a
result of the December 2021 MoPSC gas rate order effective February 28, 2022.
Purchased gas costs increased $7 million and $22 million for the three and six
months ended June 30, 2022, respectively, due to 2022 amortization of natural
gas costs previously deferred under the PGA, driven by a significant increase in
cost and customer demand as result of the extremely cold weather in mid-February
2021, partially offset by lower natural gas prices in 2022. The increased
purchased natural gas costs are fully offset by an increase in natural gas
revenues under the PGA rider, resulting in no impact to margin. The increase in
purchased natural gas cost is reflected in "Cost recovery mechanisms - offset in
natural gas revenue" and the associated recoverability from customers is
reflected in "Cost recovery mechanisms - offset in natural gas purchased for
resale" in the table above.

Ameren Illinois

Ameren Illinois' electric margins increased $50 million, or 13%, and $92
million, or 12%, for the three and six months ended June 30, 2022, respectively,
compared with the year-ago periods, driven by increased margins at Ameren
Illinois Electric Distribution and Ameren Illinois Transmission. Ameren Illinois
Natural Gas' margins increased $8 million, or 7%, and $29 million, or 9%, for
the three and six months ended June 30, 2022, respectively, compared with the
year-ago periods.

Ameren Illinois Electric Distribution

Ameren Illinois Electric Distribution's margins increased $33 million, or 11%,
and $58 million, or 10%, for the three and six months ended June 30, 2022,
respectively, compared with the year-ago periods. Purchased power costs
increased $83 million and $112 million for the three and six months ended
June 30, 2022, respectively, primarily resulting from higher electric prices.
The increased purchased power costs are fully offset by an increase in electric
revenues under the cost recovery mechanisms for purchased power, resulting in no
impact to margin. The increase in purchased power cost is reflected in "Cost
recovery mechanisms - offset in electric revenue" and the associated
recoverability from customers is reflected in "Cost recovery mechanisms - offset
in fuel and purchased power" in the table above.

The following items had a favorable effect on Ameren Illinois Electric Distribution's margins for the three and six months ended June 30, 2022, compared with the year-ago periods:



•Base rates increased due to a higher recognized ROE (+$6 million and +$8
million, respectively), as evidenced by an increase of 79 basis points in the
estimated annual average of the monthly yields of the 30-year United States
Treasury bonds, increased capital investment (+$2 million and +$4 million,
respectively), as evidenced by a 6% increase in rate base used to calculate the
revenue requirement, and higher recoverable non-purchased power expenses (+$20
million and +$39 million, respectively), partially offset by the absence in 2022
of revenue requirement reconciliation adjustment true-ups (-$4 million) recorded
in the first quarter of 2021. The sum of these changes collectively increased
margins $28 million and $47 million, respectively.
•Revenues increased $3 million and $6 million, respectively, due to the recovery
of and return on increased energy-efficiency program investments under
performance-based formula ratemaking.

Ameren Illinois Natural Gas

Ameren Illinois Natural Gas' margins increased $8 million, or 7%, and $29
million, or 9%, for the three and six months ended June 30, 2022, respectively,
compared with the year-ago periods. Purchased gas costs increased $8 million and
$121 million for the three and six months ended June 30, 2022, respectively, due
to 2022 amortization of natural gas costs previously deferred under the PGA,
driven by a significant increase in cost and customer demand as a result of the
extremely cold weather in mid-February 2021, partially offset by lower natural
gas costs in 2022. The increased purchased natural gas costs are fully offset by
an increase in natural gas revenues under the PGA rider, resulting in no impact
to margin. The increase in purchased natural gas cost is reflected in "Cost
recovery mechanisms - offset in natural gas revenue" and the associated
recoverability from customers is reflected in "Cost recovery mechanisms - offset
in natural gas purchased for resale" in the table above.

The following items had a favorable effect on Ameren Illinois Natural Gas' margins for the three and six months ended June 30, 2022 (except where a specific period is referenced):



•Revenues increased $6 million and $15 million, respectively, due to additional
investment in natural gas infrastructure under the QIP.
•Other cost recovery mechanisms increased revenues $6 million, primarily due to
increased revenues for excise taxes, for the six months ended June 30, 2022.
•Revenues increased $3 million in January 2022 due to higher base rates as a
result of the January 2021 natural gas rate order.

and maintenance expenses increased $6 million and $11 million in the three and
six months ended June 30, 2022 for activity not reported as part of a segment,
as reflected in "Other/Intersegment Eliminations" above, primarily because of an
increase in the elimination of the non-service cost component of net periodic
benefit income at Ameren Services, which is allocated to the segments and
primarily included in the segments' other operations and maintenance expenses.

Other operations and maintenance expenses increased $42 million and $49 million
in the three and six months ended June 30, 2022, compared with the year-ago
periods. The following items increased other operations and maintenance expenses
in the three and six months ended June 30, 2022, compared with the year-ago
periods (except where a specific period is referenced):

•The cash surrender value of company-owned life insurance decreased $12 million
and $18 million, respectively, primarily because of unfavorable market returns
in 2022, compared with favorable market returns in 2021.
•The absence in 2022 of $6 million and $12 million, respectively, in service
fees received under refined coal production agreements, as the result of the
expiration of refined coal tax credits at the end of 2021, which impact was
reflected in electric services rates pursuant to the December 2021 MoPSC rate
order.
•Labor and benefit costs increased $7 million and $11 million, respectively,
primarily because of increased pension service costs due to a higher base level
of expenses reflected in electric service rates pursuant to the December 2021
MoPSC rate order.
•Transmission and distribution expenditures increased $6 million in both
periods, primarily due to disciplined project management and increased storm
costs.
•The absence of a $5 million deferral to a regulatory asset of certain costs
previously incurred related to the COVID-19 pandemic, pursuant to the March 2021
MoPSC orders, which decreased other operations and maintenance expenses in the
six months ended June 30, 2021.
•Energy center operating costs increased $3 million in the six months ended
June 30, 2022, primarily because of costs related to new wind generation
facilities, which are recovered under the RESRAM.
•Customer billing costs increased $2 million in both periods, primarily because
credit card fees charged to customers were discontinued in March 2022 pursuant
to the December 2021 MoPSC rate order, which incorporated an amount of fees in
electric service rates.

The above increases in the six months ended June 30, 2022, compared with the year-ago period, were partially offset by a $12 million decrease in MEEIA customer energy-efficiency program spend as approved by the MoPSC.

Other operations and maintenance expenses increased $32 million and $61 million
in the three and six months ended June 30, 2022, compared with the year-ago
periods, as discussed below. Other operations and maintenance expenses increased
$3 million at Ameren Illinois Transmission in the three and six months ended
June 30, 2022, compared with the year-ago periods, primarily because of
decreases in the cash surrender value of company-owned life insurance related to
unfavorable market returns in 2022, compared with favorable market returns in
2021.

Ameren Illinois Electric Distribution



Other operations and maintenance expenses increased $19 million and $41 million
in the three and six months ended June 30, 2022, compared with the year-ago
periods. The following items increased other operations and maintenance expenses
in the three and six months ended June 30, 2022, compared with the year-ago
periods (except where a specific period is referenced):

•Distribution system expenditures increased $5 million and $15 million,
respectively, primarily because of projects deferred in 2021 as a result of
storm restoration efforts for which the associated costs were deferred as a
regulatory asset in 2021.
•The cash surrender value of company-owned life insurance decreased $6 million
and $9 million, respectively, primarily because of unfavorable market returns in
2022, compared with favorable market returns in 2021.
•Increased bad debt expense of $2 million and $7 million, respectively,
primarily because of increased recovery of bad debt costs allowed by the ICC.
•Injuries and damages increased $4 million in both periods, primarily because of
an increase in claims compared with the year-ago periods.
•Amortization of regulatory assets associated with customer energy-efficiency
program investments under formula ratemaking increased $2 million and $4
million, respectively.

Ameren Illinois Natural Gas



Other operations and maintenance expenses increased $10 million and $17 million
in the three and six months ended June 30, 2022, compared with the year-ago
periods, primarily because of increased distribution system expenditures of $5
million and $9 million, respectively, primarily because of a shift from capital
to operations and maintenance activity, which is expected to largely reverse in
the second half of the year. Other operations and maintenance expenses also
increased $3 million and $5 million, respectively, because of decreases in the
cash surrender value of company-owned life insurance related to unfavorable
market returns in 2022, compared with favorable market returns in 2021.

which include the effect of the additional investments:

•Depreciation and amortization rate changes pursuant to the December 2021 MoPSC
electric rate order, which increased depreciation and amortization expenses by
$17 million and $23 million, respectively.
•Increased depreciation and amortization expenses of $17 million and $23
million, respectively, for amounts previously deferred under the PISA and RESRAM
and subsequently reflected in base rates pursuant to the December 2021 MoPSC
electric rate order, largely due to investments in wind generation.
•Fewer deferrals of depreciation and amortization expenses of $15 million in
both periods due to less property, plant, and equipment eligible for recovery
under the PISA and RESRAM as a result of the December 2021 MoPSC electric rate
order.
•The net deferral related to the Meramec Energy Center retirement, which
decreased depreciation and amortization expenses by $15 million and $20 million,
respectively, pursuant to the December 2021 MoPSC electric rate order.
•The net under-recovery of RESRAM eligible expenses, which decreased
depreciation and amortization expenses by $9 million and $14 million,

Taxes other than income taxes increased $7 million in the three months ended
June 30, 2022, compared with the year-ago period, primarily because of a $4
million increase in excise taxes at Ameren Missouri, primarily because of
increased sales. Taxes other than income taxes increased $21 million in the six

of $7 million increases in excise taxes at both Ameren Missouri and Ameren
Illinois Natural Gas, primarily because of increased sales. Taxes other than
income taxes also increased $6 million in the six months ended June 30, 2022,
compared with the year-ago period, at Ameren Missouri because of increased
property taxes, primarily resulting from higher assessed values and lower
property tax refunds.

Interest charges increased $30 million and $34 million in the three and six months ended June 30, 2022, compared with the year-ago periods. The following items increased interest charges in the three and six months ended June 30, 2022, compared with the year-ago periods:



•Interest charges at Ameren and Ameren Missouri reflected a deferral to a
regulatory asset of interest charges pursuant to PISA and RESRAM. The amount of
interest charges included in base rates for PISA and RESRAM deferrals was
updated when new customer rates became effective on February 28, 2022, pursuant
to the December 2021 MoPSC electric rate order, which incorporated deferrals
through September 30, 2021. Lower deferrals due to the inclusion in base rates
of interest associated with certain property, plant, and equipment previously
deferred under the PISA and RESRAM, increased interest charges by $15 million
and $12 million, respectively.
•Issuances of long-term debt at Ameren Missouri in June 2021 and April 2022
collectively increased interest charges by $8 million and $10 million,
respectively.
•Issuances of long-term debt at Ameren (parent) in March and November 2021

See Note 12 - Income Taxes under Part I, Item 1, of this report for a reconciliation of the federal statutory corporate income tax rate to the effective income tax rate for the Ameren Companies.



The effective income tax rate was lower at Ameren Illinois Natural Gas in the
three months ended June 30, 2022, compared with the year-ago period, primarily
because of higher amortization of excess deferred taxes.

LIQUIDITY AND CAPITAL RESOURCES



Collections from our tariff-based revenues are our principal source of cash
provided by operating activities. A diversified retail customer mix, primarily
consisting of rate-regulated residential, commercial, and industrial customers,
provides us with a reasonably predictable source of cash. In addition to using
cash provided by operating activities, we use available cash, drawings under
committed credit agreements, commercial paper issuances, and/or, in the case of
Ameren Missouri and Ameren Illinois, short-term affiliate borrowings to support
normal operations and temporary capital requirements. We may reduce our
short-term borrowings with cash provided by operations or, at our discretion,
with long-term borrowings, or, in the case of Ameren Missouri and Ameren
Illinois, with capital contributions from Ameren (parent). As of June 30, 2022,
there have been no material changes other than in the ordinary course of
business related to cash requirements arising from these long-term commitments
provided in Item 7 of the Form 10-K for the year ended December 31, 2021. In
April and May 2022, Ameren Illinois conducted procurement events, administered
by the IPA, to purchase energy products and acquire capacity through May 2025.
As a result, Ameren and Ameren Illinois' estimated minimum purchase obligations
for purchased power increased by $0.5 billion in total over the period of June
2022 through May 2025.

We expect to make significant capital expenditures over the next five years,
supported by a combination of long-term debt and equity, as we invest in our
electric and natural gas utility infrastructure to support overall system
reliability, grid modernization, renewable energy target requirements,
environmental compliance, and other improvements. For additional information
about our long-term debt outstanding, including maturities due within one year,
and the applicable interest rates, see Note 5 - Long-term Debt and Equity
Financings under Part II, Item 8 of the Form 10-K and Note 4 - Long-term Debt
and Equity Financings under Part I, Item 1, of this report. As part of its
funding plan for capital expenditures, Ameren is using newly issued shares of
common stock, rather than market-purchased shares, to satisfy requirements under
the DRPlus and employee benefit plans and expects to continue to do so through
at least 2026. Ameren expects these issuances to provide equity of about
$100 million annually. In addition, in 2021, Ameren established an ATM program
under which Ameren may offer and sell from time to time up to $750 million of
its common stock, which includes the ability to enter into forward sales
agreements, subject to market conditions and other factors. There were no shares
issued under the ATM program for the three and six months ended June 30, 2022.
Ameren has entered into multiple forward sale agreements under the ATM program
with various counterparties relating to 5.8 million shares of common stock. As
of June 30, 2022, Ameren could have settled the forward sale agreements with
physical delivery of 5.6 million shares of common stock to the respective
counterparties in exchange for cash of $500 million. As of June 30, 2022, Ameren
had approximately $90 million of common stock available under the ATM program,
which takes into account the forward sale agreements in effect as of June 30,
2022. Ameren expects to settle approximately $300 million of the forward sale
agreements by December 31, 2022. Ameren plans to issue approximately $300
million of equity each year from 2022 to 2026 in addition to issuances under the
DRPlus and employee benefit plans. Ameren expects its equity to total
capitalization ratio to be approximately 45% through December 31, 2026, with the
long-term intent to support solid investment-grade credit ratings. See Long-term
Debt and Equity below and Note 4 - Long-term Debt and Equity Financings under
Part I, Item 1, of this report for additional information on the ATM program,
including the forward sale agreements under the ATM program relating to common
stock.

The use of cash provided by operating activities and short-term borrowings to
fund capital expenditures and other long-term investments at the Ameren
Companies frequently results in a working capital deficit, defined as current
liabilities exceeding current assets, as was the case at June 30, 2022, for
Ameren and Ameren Illinois. With the credit capacity available under the Credit
Agreements, and cash and cash equivalents, Ameren (parent), Ameren Missouri, and
Ameren Illinois, collectively, had net available liquidity of $1.3 billion at
June 30, 2022. See Credit Facility Borrowings and Liquidity for additional
information.

payable, among other things, as well as the unique regulatory environment for
each of our businesses. Substantially all expenditures related to fuel,
purchased power, and natural gas purchased for resale are recovered from
customers through rate adjustment mechanisms, which may be adjusted without a
traditional rate proceeding. Similar regulatory mechanisms exist for certain
other operating expenses that can also affect the timing of cash provided by
operating activities. The timing of cash payments for costs recoverable under
our regulatory mechanisms differs from the recovery period of those costs.
Additionally, the seasonality of our electric and natural gas businesses,
primarily caused by seasonal customer rates and changes in customer demand due
to weather, such as increased demand resulting from the extremely cold weather
in mid-February 2021 discussed below, significantly affects the amount and
timing of our cash provided by operating activities.

As a result of the significant increase in customer demand and prices for
natural gas and electricity experienced in mid-February 2021 due to extremely
cold weather, Ameren Missouri and Ameren Illinois had under-recovered costs for
the month of February 2021 under their PGA clauses and, for Ameren Missouri,
under the FAC (Ameren Missouri - PGA $53 million, FAC $50 million; Ameren
Illinois - PGA $221 million). Ameren Missouri's PGA under-recovery is being
collected from customers over 36 months beginning November 2021, pursuant to an
October 2021 MoPSC order, and the FAC under-recovery was collected over eight
months beginning October 2021. Ameren Illinois is collecting the PGA
under-recovery over 18 months beginning April 2021.

Ameren's cash provided by operating activities increased $436 million in the
first six months of 2022, compared with the year-ago period. The following items
contributed to the increase:

•A $574 million increase resulting from increased customer collections and
decreased expenditures under the PGA and FAC, primarily as a result of the
significant increase from customer demand and prices for natural gas and
electricity experienced in mid-February 2021 due to extremely cold weather, a
net increase attributable to other regulatory recovery mechanisms, and higher
customer collections resulting from base rate increases pursuant to Ameren
Missouri's December 2021 electric rate order.
•A $20 million decrease in coal inventory levels at Ameren Missouri, as less
coal was purchased in 2022 due to service-related delivery disruptions.
•A $14 million decrease in major storm restoration costs at Ameren Illinois,
primarily due to a January 2021 storm.
•An $11 million decrease in payments to settle ARO liabilities, primarily
related to the closure of Ameren Missouri's CCR storage facilities.
•An $8 million decrease in the cost of natural gas held in storage, primarily at
Ameren Illinois, because of an increase in withdrawals between periods.

The following items partially offset the increase in Ameren's cash from operating activities between periods:



•A $77 million increase in net collateral posted with counterparties, primarily
due to changes in the market prices of power, natural gas, and other fuels.
•A $39 million increase in payments for nuclear refueling and maintenance
outages at Ameren Missouri's Callaway Energy Center. There was no scheduled
refueling and maintenance outage in 2021.
•A $30 million increase in purchases of materials and supplies inventories to
support operations in 2022 as levels were increased to mitigate against any
potential supply disruptions.
•A $23 million increase in payments for certain cloud computing arrangements.
•The absence in 2022 of $15 million in service fees received under refined coal
production agreements at Ameren Missouri, as the result of the expiration of
refined coal tax credits at the end of 2021.
•A $20 million increase in interest payments, primarily due to an increase in
the average outstanding debt.
•A $13 million increase in property tax payments at Ameren Missouri, primarily
due to higher assessed property tax values.

Cash Flows from Investing Activities

Ameren's cash used in investing activities decreased $208 million during the
first six months of 2022, compared with the year-ago period, primarily as a
result of a $225 million decrease in capital expenditures, largely resulting
from a reduction in expenditures related to wind generation assets at Ameren
Missouri, partially offset by increased expenditures for electric delivery
infrastructure upgrades at Ameren Missouri and for transmission projects at
Ameren Illinois. The decrease in Ameren's cash used in investing activities was
partially offset by an $18 million increase due to the timing of nuclear fuel
expenditures at Ameren Missouri.

Ameren Missouri's cash used in investing activities decreased $235 million
during the first six months of 2022, compared with the year-ago period,
primarily as a result of a $295 million decrease in capital expenditures,
primarily resulting from a reduction in expenditures related to wind generation
assets partially offset by increased expenditures for electric delivery
infrastructure upgrades. This decrease was partially offset by a $47 million
return of net money pool advances in the first six months of 2021, and an
$18 million increase due to the timing of nuclear fuel expenditures.

Ameren Illinois' cash used in investing activities increased $31 million during
the first six months of 2022, compared with the year-ago period, primarily as a
result of a $53 million increase in capital expenditures, largely related to
transmission projects. This increase was partially offset by a $20 million
decrease in Ameren Illinois' net money pool advances.

Cash Flows from Financing Activities



Cash provided by, or used in, financing activities is a result of our financing
needs, which depend on the level of cash provided by operating activities, the
level of cash used in investing activities, the level of dividends, and our
long-term debt maturities, among other things. Due to extremely cold winter
weather in mid-February 2021, Ameren Missouri and Ameren Illinois experienced
higher than anticipated commodity costs for natural gas purchased for resale and
purchased power, which contributed to the acceleration of the timing of certain
planned 2021 debt issuances.

Ameren's cash provided by consolidated financing activities decreased
$604 million during the first six months of 2022, compared with the year-ago
period. During the first six months of 2022, Ameren utilized proceeds of $524
million of long-term debt to repay then-outstanding short-term debt and for
near-term capital expenditures. In addition, during the first six months of
2022, Ameren utilized proceeds from net commercial paper issuances of
$475 million along with cash provided by operating activities to fund, in part,
investing activities. In comparison, during the first six months of 2021, Ameren
utilized proceeds from the issuance of $1,423 million of long-term debt for
general corporate purposes, including to repay then-outstanding short-term debt,
including short-term debt in connection with the increased purchases for natural
gas for resale and purchased power costs as a result of the significant increase
in customer demand and prices for natural gas and electricity experienced in
mid-February 2021 due to extremely cold weather, and to fund, in part, investing
activities. During the first six months of 2021, Ameren repaid net short-term
debt of $59 million. In addition, Ameren received aggregate cash proceeds of
$258 million from the issuance of common stock under the ATM program, the
DRPlus, and the 401(k) plan and the settlement of the remaining portion of the
2019 forward sale agreement. These proceeds were used to fund a portion of
Ameren Missouri's wind generation investments and to fund, in part, other
investing activities. During the first six months of 2022, Ameren paid common
stock dividends of $305 million, compared with $282 million in the year-ago
period, as a result of an increase in both the dividend rate and the number of
common shares outstanding.

Ameren Missouri's cash provided by financing activities decreased $65 million
during the first six months of 2022, compared with the year-ago period. During
the first six months of 2022, Ameren Missouri utilized proceeds from the
issuance of $524 million to repay then-outstanding short-term debt and for
near-term capital expenditures. In addition, during the first six months of
2022, Ameren Missouri utilized proceeds from net commercial paper issuances of
$120 million along with cash provided by operating activities to fund, in part,
investing activities. In comparison, during the first six months of 2021, Ameren
Missouri utilized net proceeds from the issuance of long-term debt of $524
million to repay then-outstanding short-term debt, including short-term debt
incurred in connection with the increased purchases for natural gas for resale
and purchased power costs as a result of the significant increase in customer
demand and prices for natural gas and electricity experienced in mid-February
2021 due to extremely cold weather. Additionally, proceeds from the issuance of
long-term debt and capital contributions of $183 million from Ameren (parent)
were used to fund a portion of wind generation investments and to fund, in part,
investing activities during the first six months of 2021.

Ameren Illinois' cash provided by financing activities decreased $440 million
during the first six months of 2022, compared with the year-ago period. During
the first six months of 2022, Ameren Illinois utilized proceeds from net
commercial paper issuances of $38 million and cash provided by operating
activities to fund, in part, investing activities. In comparison, during the
first six months of 2021, Ameren Illinois utilized net proceeds from the
issuance of long-term debt of $449 million to repay then-outstanding short-term
debt, including short-term debt incurred in connection with the increased
purchases for natural gas for resale and purchased power costs as a result of
the significant increase in customer demand and prices for natural gas and
electricity experienced in mid-February 2021 due to extremely cold weather, and
to fund, in part, investing activities. Ameren Illinois also received a
$70 million capital contribution from Ameren (parent) during the first six
months of 2021. In addition, Ameren repaid $19 million of money pool borrowings
and redeemed $13 million of preferred stock during the first six months of 2021.

(a)Does not include Ameren's forward equity sale agreements. See Note 4 - Long-term Debt and Equity Financings under Part I, Item 1, of this report for additional information.



The Credit Agreements, among other things, provide $2.3 billion of credit until
maturity in December 2025. See Note 3 - Short-term Debt and Liquidity under
Part I, Item 1, of this report for additional information on the Credit
Agreements. During the six months ended June 30, 2022, Ameren (parent), Ameren
Missouri, and Ameren Illinois each issued commercial paper. Borrowings under the
Credit Agreements and commercial paper issuances are based upon available
interest rates at that time of the borrowing or issuance.

Ameren has a money pool agreement with and among its utility subsidiaries to
coordinate and to provide for certain short-term cash and working capital
requirements. As short-term capital needs arise, and based on availability of
funding sources, Ameren Missouri and Ameren Illinois will access funds from the
utility money pool, the Credit Agreements, or the commercial paper programs
depending on which option has the lowest interest rates.

See Note 3 - Short-term Debt and Liquidity under Part I, Item 1, of this report
for additional information on credit agreements, commercial paper issuances,
Ameren's money pool arrangements and related borrowings, and relevant interest
rates.

The issuance of short-term debt securities by Ameren's utility subsidiaries is
subject to FERC approval under the Federal Power Act. In March 2022, the FERC
issued an order authorizing Ameren Missouri to issue up to $1 billion of
short-term debt securities through March 2024. In 2020, the FERC issued an order
authorizing Ameren Illinois to issue up to $1 billion of short-term debt
securities through September 2022. In 2021, the FERC issued an order authorizing
ATXI to issue up to $300 million of short-term debt securities, which expires in
July 2023.

The Ameren Companies continually evaluate the adequacy and appropriateness of
their liquidity arrangements for changing business conditions. When business
conditions warrant, changes may be made to existing credit agreements or to
other borrowing arrangements, or other arrangements may be made.

Indebtedness Provisions and Other Covenants



At June 30, 2022, the Ameren Companies were in compliance with the provisions
and covenants contained in their credit agreements, indentures, and articles of
incorporation, as applicable, and ATXI was in compliance with the provisions and
covenants contained in its note purchase agreements. See Note 3 - Short-term
Debt and Liquidity under Part I, Item 1, of this report and Note 4 - Short-term
Debt and Liquidity and Note 5 - Long-term Debt and Equity Financings under
Part II, Item 8, of the Form 10-K for a discussion of provisions, applicable
cross-default provisions, and covenants contained in our credit agreements, in
ATXI's note purchase agreements, and in certain of the Ameren Companies'
indentures and articles of incorporation.

We consider access to short-term and long-term capital markets to be a
significant source of funding for capital requirements not satisfied by cash
provided by our operating activities. Inability to raise capital on reasonable
terms, particularly during times of uncertainty in the capital markets, could
negatively affect our ability to maintain and expand our businesses. After
assessing its current operating performance, liquidity, and credit ratings (see
Credit Ratings below), Ameren, Ameren Missouri, and Ameren Illinois each
believes that it will continue to have access to the capital markets on
reasonable terms. However, events beyond Ameren's, Ameren Missouri's, and Ameren
Illinois' control may create uncertainty in the capital markets or make access
to the capital markets uncertain or limited. Such events could increase our cost
of capital and adversely affect our ability to access the capital markets.

Dividends



The amount and timing of dividends payable on Ameren's common stock are within
the sole discretion of Ameren's board of directors. Ameren's board of directors
has not set specific targets or payout parameters when declaring common stock
dividends, but it considers various factors, including Ameren's overall payout
ratio, payout ratios of our peers, projected cash flow and potential future cash
flow requirements, historical earnings and cash flow, projected earnings,
impacts of regulatory orders or legislation, and other key business
considerations. Ameren expects its dividend payout ratio to be between 55% and
70% of annual earnings over the next few years.

See Note 4 - Short-term Debt and Liquidity and Note 5 - Long-term Debt and
Equity Financings under Part II, Item 8, of the Form 10-K for additional
discussion of covenants and provisions contained in certain of the Ameren
Companies' financial agreements and articles of incorporation that would
restrict the Ameren Companies' payment of dividends in certain circumstances. At
June 30, 2022, none of these circumstances existed at Ameren, Ameren Missouri,
or Ameren Illinois and, as a result, these companies were not restricted from
paying dividends.

The following table presents common stock dividends declared and paid by Ameren Corporation to its common shareholders and by Ameren subsidiaries to their parent, Ameren Corporation, for the six months ended June 30, 2022 and 2021:

Collateral Postings



Any weakening of our credit ratings may reduce access to capital and trigger
additional collateral postings and prepayments. Such changes may also increase
the cost of borrowing, resulting in an adverse effect on earnings. Cash
collateral postings and prepayments made with external parties, including
postings related to exchange-traded contracts, were $222 million, $199 million,
and $23 million for Ameren, Ameren Missouri, and Ameren Illinois, respectively,
and cash collateral posted by external parties were $75 million, $15 million,
and $60 million for Ameren, Ameren Missouri, and Ameren Illinois, respectively,
at June 30, 2022. A sub-investment-grade issuer or senior unsecured debt rating
(below "Baa3" from Moody's or below "BBB-" from S&P) at June 30, 2022, could
have resulted in Ameren, Ameren Missouri, or Ameren Illinois being required to
post additional collateral or other assurances for certain trade obligations
amounting to $166 million, $89 million, and $77 million, respectively.

Changes in commodity prices could trigger additional collateral postings and
prepayments. Based on credit ratings at June 30, 2022, if market prices were 15%
higher or lower than June 30, 2022 levels in the next 12 months and 20% higher
or lower thereafter through the end of the term of the commodity contracts, then
Ameren, Ameren Missouri, and Ameren Illinois could be required to post an
immaterial amount, compared to each company's liquidity, of collateral or
provide other assurances for certain trade obligations.

OUTLOOK



Below are some key trends, events, and uncertainties that may reasonably affect
our results of operations, financial condition, or liquidity, as well as our
ability to achieve strategic and financial objectives, for 2022 and beyond. For
additional information regarding recent rate orders, lawsuits, and pending
requests filed with state and federal regulatory commissions, including those
discussed below, see Note 2 - Rate and Regulatory Matters under Part I, Item 1,
of this report and Note 2 - Rate and Regulatory Matters under Part II, Item 8,
of the Form 10-K.

Operations

•In the first half of 2022, our sales volumes, which have been, and continue to
be, affected by the COVID-19 pandemic, among other things, increased compared to
the same period in 2021, excluding the estimated effects of weather and customer
energy-efficiency programs. While total sales volume levels at Ameren Missouri
were comparable to pre-pandemic levels for the first six months of 2022, Ameren
Illinois' sales remain below pre-pandemic levels. However, revenues from Ameren
Illinois' electric distribution business, residential and small nonresidential
customers of Ameren Illinois' natural gas distribution business, and Ameren
Illinois' and ATXI's electric transmission businesses are decoupled from changes
in sales volumes. There has also been a shift in sales volumes by customer class
at both Ameren Missouri and Ameren Illinois, which began in 2020, with an
increase in residential sales, and a decrease in commercial and industrial
sales. The continued effect of the COVID-19 pandemic on our results of
operations, financial position, and liquidity in subsequent periods will depend
on its severity and longevity, future regulatory or legislative actions with
respect thereto, and the resulting impact on business, economic, and capital
market conditions.

•The PISA permits Ameren Missouri to defer and recover 85% of the depreciation
expense and earn a return at the applicable WACC on investments in certain
property, plant, and equipment placed in service, and not included in base
rates. The regulatory asset for accumulated PISA deferrals also earns a return
at the applicable WACC, with all approved PISA deferrals added to rate base
prospectively and recovered over a period of 20 years following a regulatory
rate review. Additionally, under the RESRAM, Ameren Missouri is permitted to
recover the 15% of depreciation expense not recovered under the PISA, and earn a
return at the applicable WACC for investments in renewable generation plant
placed in service to comply with Missouri's renewable energy standard.
Accumulated RESRAM deferrals earn carrying costs at short-term interest rates.
The PISA and the RESRAM mitigate the effects of regulatory lag between
regulatory rate reviews. Those investments not eligible for recovery under the
PISA and the remaining 15% of certain property, plant, and equipment placed in
service, unless eligible for recovery under the RESRAM, remain subject to
regulatory lag. Ameren Missouri defers its cost of debt relating to PISA
eligible investments as an offset to interest charges with the difference
between the applicable WACC and its cost of debt recognized in revenues when
recovery of such deferrals is reflected in customer rates. As a result of the
PISA election, additional provisions of the law apply to Ameren Missouri,
including limitations on electric customer rate increases. Ameren Missouri does
not expect to exceed these rate increase limitations in 2022. In June 2022,
Missouri Senate Bill 745 was enacted and will become effective on August 28,
2022. The law extended Ameren Missouri's PISA election through December 2028 and
allows for an additional five-year extension through December 2033 if requested
by Ameren Missouri and approved by the MoPSC, among other things. The law
established a 2.5% annual limit on increases to the electric service revenue
requirement used to set customer rates due to the inclusion of incremental PISA
deferrals in the revenue requirement. The limitation will be effective for
revenue requirements approved by the MoPSC after January 1, 2024, and will be
based on the revenue requirement established in the immediately preceding rate
order. The current rate limitation, which is effective through 2023, is a 2.85%
cap on the compound annual growth rate in the average overall customer rate per
kilowatthour, based on the electric rates that became effective in April 2017,
less half of the annual savings from the TCJA that was passed on to customers as
approved in a July 2018 MoPSC order.

•In 2018, the MoPSC issued an order approving Ameren Missouri's MEEIA 2019 plan.
The plan includes a portfolio of customer energy-efficiency and demand response
programs through December 2023 and low-income customer energy-efficiency
programs through December 2024, along with a rider. Ameren Missouri intends to
invest approximately $360 million over the life of the plan, including
$80 million in 2022 and $75 million in 2023. The plan includes the continued use
of the MEEIA rider, which allows Ameren Missouri to collect from, or refund to,
customers any difference in actual MEEIA program costs and related lost electric
margins and the amounts collected from customers. In addition, the plan includes
a performance incentive that provides Ameren Missouri an opportunity to earn
additional revenues by achieving certain customer energy-efficiency goals. If
the target goals were achieved for 2021 and are achieved for 2022, additional
revenues of $24 million would be recognized in 2022, and, if target goals are
achieved for 2023, additional revenues of $13 million would be recognized in
2023.

•In August 2022, Ameren Missouri filed a request with the MoPSC seeking approval
to increase its annual revenues for electric service by $316 million. The MoPSC
proceeding relating to the proposed electric service rate changes will take
place over a period of up to 11 months, with a decision by the MoPSC expected by
June 2023 and new rates effective by July 2023. Ameren Missouri cannot predict
the level of any electric service rate change the MoPSC may approve, whether the
requested regulatory recovery mechanisms will be approved, or whether any rate
change that may eventually be approved will be sufficient for Ameren Missouri to
recover its costs and earn a reasonable return on its investments when the rate
change goes into effect.

•In December 2021, the MoPSC issued an order in Ameren Missouri's 2021 electric
service regulatory rate review, resulting in an increase of $220 million to
Ameren Missouri's annual revenue requirement for electric retail service. As a
result of this order, Ameren Missouri expects a year-over-year increase to 2022
earnings, compared to 2021, primarily in the third quarter of 2022 due to
seasonal electric customer rates and higher demand during the summer. Ameren
Missouri expects earnings to increase approximately $23 million in the third
quarter of 2022, compared to the same period in 2021.

•Ameren Illinois and ATXI use a forward-looking rate calculation with an annual
revenue requirement reconciliation for each company's electric transmission
business. Based on expected rate base and the currently allowed 10.52% ROE,
which includes a 50 basis point incentive adder for participation in an RTO, the
revenue requirements included in 2022 rates for Ameren Illinois' and ATXI's
electric transmission businesses are $422 million and $195 million,
respectively. These revenue requirements represent an increase in Ameren
Illinois' revenue requirement of $42 million and a decrease in ATXI's revenue
requirement of $5 million from the revenue requirements reflected in 2021 rates,
primarily due to higher expected rate base at Ameren Illinois and a lower
expected rate base at ATXI. These rates will affect Ameren Illinois' and ATXI's
cash receipts during 2022, but will not determine their respective electric
transmission service operating revenues, which will instead be based on 2022
actual recoverable costs, rate base, and a return on rate base at the applicable
WACC as calculated under the FERC formula ratemaking framework.

•The allowed base ROE for FERC-regulated transmission rates previously charged
under the MISO tariff is the subject of an appeal filed with the United States
Court of Appeals for the District of Columbia Circuit. Depending on the outcome
of the appeal, the transmission rates charged during previous periods and the
currently effective rates may be subject to change. Additionally, in March 2019,
the FERC issued a Notice of Inquiry regarding its transmission incentives
policy. In March 2020, the FERC issued a Notice of Proposed Rulemaking on its
transmission incentives policy, which addressed many of the issues in the Notice
of Inquiry on transmission incentives. The Notice of Proposed Rulemaking
included an increased incentive ROE for participation in an RTO to 100 basis
points from the current 50 basis points and revised the parameters for awarding
incentives, while limiting the overall incentives to a cap of 250 basis points,
among other things. In April 2021, the FERC issued a Supplemental Notice of
Proposed Rulemaking, which proposes to modify the Notice of Proposed
Rulemaking's incentive for participation in an RTO by limiting this incentive
for utilities that join an RTO to 50 basis points and only allowing them to earn
the incentive for three years, among other things. If this proposal is included
in a final rule, Ameren Illinois and ATXI would no longer be eligible for the 50
basis point RTO incentive adder, prospectively. The FERC is under no deadline to
issue a final rule on this matter. Ameren is unable to predict the ultimate
impact of any changes to the FERC's incentives policy, or any further order on
base ROE. A 50 basis point change in the FERC-allowed ROE would affect Ameren's
and Ameren Illinois' annual net income by an estimated $12 million and
$8 million, respectively, based on each company's 2022 projected rate base.

•Ameren Illinois' electric distribution service performance-based formula
ratemaking framework under the IEIMA allows Ameren Illinois to reconcile
electric distribution service rates to its actual revenue requirement on an
annual basis to reflect actual recoverable costs incurred and a return at the
applicable WACC on year-end rate base. If a given year's revenue requirement
varies from the amount collected from customers, an adjustment is made to
electric operating revenues with an offset to a regulatory asset or liability to
reflect that year's actual revenue requirement, independent of actual sales
volumes. The regulatory balance is then collected from, or refunded to,
customers within two years from the end of the year. Pursuant to an order issued
by the ICC in March 2021, Ameren Illinois expects to use the current IEIMA
formula framework to establish annual customer rates effective through 2023, and
reconcile the related revenue requirement for customer rates established for
2022 and 2023. As such, Ameren Illinois' 2022 and 2023 revenues would reflect
each year's actual recoverable costs, year-end rate base, and a return at the
applicable WACC, with the ROE component based on the annual average of the
monthly yields of the 30-year United States Treasury bonds plus 580 basis
points. For more information on the March 2021 ICC order, see Note 2 - Rate and
Regulatory Matters under Part II, Item 8, of the Form 10-K. By law, the
decoupling

provisions extend beyond the end of existing performance-based formula ratemaking, which ensures that Ameren Illinois' electric distribution revenues authorized in a regulatory rate review are not affected by changes in sales volumes.



•Pursuant to the IETL, which was enacted in September 2021, Ameren Illinois may
file an MYRP with the ICC to establish base rates for electric distribution
service to be charged to customers for each calendar year of a four-year period.
An MYRP would allow Ameren Illinois to reconcile electric distribution service
rates to its actual revenue requirement on an annual basis, subject to a
reconciliation cap and adjustments to the ICC-determined ROE for performance
incentives and penalties. Ameren Illinois' existing riders will remain effective
whether it elects to file an MYRP or a traditional regulatory rate review.
Additionally, electric distribution service revenues would continue to be
decoupled from sales volumes under either election. Subject to a constructive
outcome regarding the ICC's determination of performance metrics, Ameren
Illinois anticipates filing an MYRP by mid-January 2023, with rates effective
beginning in 2024. If Ameren Illinois does not file an MYRP for rates effective
beginning in 2024, its next opportunity to file an MYRP would be for rates
effective beginning in 2028. For additional information regarding ratemaking
under an MYRP, including details of the reconciliation cap, see Note 2 - Rate
and Regulatory Matters under Part II, Item 8, of the Form 10-K.

•In 2021, the ICC issued an order in Ameren Illinois' annual update filing that
approved a $58 million increase in Ameren Illinois' electric distribution
service rates beginning in January 2022. Ameren Illinois' 2022 electric
distribution service revenues will be based on its 2022 actual recoverable
costs, 2022 year-end rate base, and a return at the applicable WACC, with the
ROE component based on the annual average of the monthly yields of the 30-year
United States Treasury bonds plus 580 basis points. As of June 30, 2022, Ameren
Illinois expects its 2022 electric distribution year-end rate base to be
$3.9 billion. The 2022 revenue requirement reconciliation adjustment will be
collected from, or refunded to, customers in 2024. A 50 basis point change in
the annual average of the monthly yields of the 30-year United States Treasury
bonds would result in an estimated $11 million change in Ameren's and Ameren
Illinois' annual net income, based on Ameren Illinois' 2022 projected year-end
rate base, including electric energy-efficiency investments. Ameren Illinois'
recognized ROE for the first six months of 2022 was based on an estimated annual
average of the monthly yields of the 30-year United States Treasury bonds of
3.10%.

•In April 2022, Ameren Illinois filed its annual electric distribution service
performance-based formula rate update with the ICC to be used for 2023 rates. In
July 2022, Ameren Illinois filed a revised request seeking to increase its
annual revenues for electric distribution service by $84 million. In June 2022,
the ICC staff submitted its calculation of the revenue requirement included in
Ameren Illinois' update filing, recommending a $60 million increase in Ameren
Illinois' electric distribution service rates. An ICC decision in this
proceeding is required by December 2022, with new rates effective in January
2023. These rates will affect Ameren Illinois' cash receipts during 2023, but
will not affect electric distribution service revenues, which will be based on
2023 actual recoverable costs, 2023 year-end rate base, and a return at the
applicable WACC as calculated under the Illinois performance-based formula
ratemaking framework.

•Pursuant to Illinois law, Ameren Illinois' electric energy-efficiency
investments are deferred as a regulatory asset and earn a return at the
applicable WACC, with the ROE component based on the annual average of the
monthly yields of the 30-year United States Treasury bonds plus 580 basis
points. The allowed ROE on electric energy-efficiency investments can be
increased or decreased by up to 200 basis points, depending on the achievement
of annual energy savings goals. While the ICC has approved a plan for Ameren
Illinois to invest approximately $120 million per year in electric
energy-efficiency programs through 2025, the ICC has the ability to reduce the
amount of electric energy-efficiency savings goals in future plan program years
if there are insufficient cost-effective programs available, which could reduce
the investments in electric energy-efficiency programs. The electric
energy-efficiency program investments and the return on those investments are
collected from customers through a rider and are not recovered through the
electric distribution service performance-based formula ratemaking framework.

•Ameren Missouri's next refueling and maintenance outage at its Callaway energy
center is scheduled for the fall of 2023. During a scheduled refueling, which
occurs every 18 months, maintenance expenses are deferred as a regulatory asset
and amortized until the completion of the next refueling and maintenance outage.
During an outage, depending on the availability of its other generation sources
and the market prices for power, Ameren Missouri's purchased power costs may
increase and the amount of excess power available for sale may decrease versus
non-outage years. Changes in purchased power costs and excess power available
for sale are included in the FAC, which results in limited impacts to earnings.
In addition, Ameren Missouri may incur increased non-nuclear energy center
maintenance costs in non-outage years.

•Ameren Missouri continues to experience coal transportation disruptions in
2022, resulting in coal inventory levels below targeted levels at the Labadie,
Rush Island, and Sioux energy centers as of the end of July 2022. Prolonged
disruptions in the delivery of coal could have adverse effects on Ameren
Missouri's electric generation operations and could result in increased
purchased power expense. Under the FAC, 95% of the variance in net energy costs,
which includes purchased power expense, from the amount set in base rates is
expected to be recovered. Further, the timing of payments for purchased power
costs compared to the recovery through customer rates under the FAC could have
adverse effects on Ameren and Ameren Missouri's liquidity.

•In December 2021, Ameren Missouri filed a motion with the United States
District Court for the Eastern District of Missouri to modify a September 2019
remedy order issued by the district court to allow the retirement of the Rush
Island Energy Center in advance of its previously expected useful life in lieu
of installing a flue gas desulfurization system. In June 2022, Ameren Missouri
supplemented its filing with the district court by proposing reduced operations,
mostly operating during peak demand times and emergencies until the energy
center is retired. The March 31, 2024 compliance date contained in the district
court's September 2019 remedy order remains in effect unless extended by the
district court. In July 2022, in response to an Ameren Missouri request for a
final, binding reliability assessment, the MISO designated the Rush Island
Energy Center as a system support resource and concluded that certain mitigation
measures, including transmission upgrades, should occur before the energy center
is retired. The transmission upgrade projects have been approved by the MISO,
and Ameren Missouri has started design and procurement activities necessary to
complete the upgrades and expects to complete the upgrades by late 2025. The
FERC will need to approve a system support resource agreement detailing the
manner of continued operation of the Rush Island Energy Center, as well as a
request from Ameren Missouri for recovery of non-energy costs under the related
MISO tariff. The agreement, if approved, would have a term of 12 months. The
system support resource designation and the related agreement are subject to
renewal and revision. Any difference between revenues and costs under the MISO
tariff is expected to be included in the FAC. The district court has the
authority to determine the retirement date and operating parameters for the Rush
Island Energy Center and is not bound by the MISO determination of the Rush
Island Energy Center as a system support resource or the FERC's approval. While
the district court is under no deadline to issue a ruling modifying the remedy
order, a decision is expected in the near term. For additional information on
the NSR and Clean Air Act litigation, see Note 9 - Commitments and Contingencies
under Part I, Item 1, of this report. Ameren Missouri filed a 2022 Change to the
2020 IRP with the MoPSC in June 2022 to reflect, among other things, the planned
acceleration of the retirement of the Rush Island Energy Center from 2039, the
retirement year for the facility as reflected in the 2020 IRP. In February 2022,
the MoPSC issued an order directing the MoPSC staff to review Ameren Missouri's
planned accelerated retirement of the Rush Island Energy Center, including
potential impacts on the reliability and cost of Ameren Missouri's service to
its customers; Ameren Missouri's plans to mitigate the customer impacts of the
accelerated retirement; and the prudence of Ameren Missouri's actions and
decisions with regard to the Rush Island Energy Center, which is expected to be
addressed in the current electric service regulatory rate review, among other
things. In April 2022, the MoPSC staff filed an initial report with the MoPSC in
which the staff concluded early retirement of the Rush Island Energy Center may
cause reliability concerns. The MoPSC staff is under no deadline to complete
this review. As of December 31, 2021, and June 30, 2022, Ameren and Ameren
Missouri classified the remaining net book value of the Rush Island Energy
Center as plant to be abandoned, net, within "Property, Plant, and Equipment,
Net" on Ameren's and Ameren Missouri's balance sheets. As part of the assessment
of any potential future abandonment loss, consideration will be given to rate
and securitization orders issued by the MoPSC to Ameren Missouri and to orders
issued to other Missouri utilities with similar facts.

•The IETL established emission standards that became effective in September
2021. Ameren Missouri's natural gas-fired energy centers in Illinois are subject
to limits on emissions, including CO2 and NOx, equal to their unit-specific
average emissions from 2018 through 2020, for any rolling twelve-month period
beginning October 1, 2021, through 2029. Further reductions to emissions limits
will become effective between 2030 and 2040, resulting in the closure of the
Venice Energy Center by 2029. The reductions could also limit the operations of
Ameren Missouri's other four natural gas-fired energy centers located in the
state of Illinois, and will result in their closure by 2040. These energy
centers are utilized to support peak loads. Subject to conditions in the IETL,
these energy centers may be allowed to exceed the emissions limits in order to
maintain reliability of electric utility service as necessary. Ameren Missouri
filed a 2022 Change to the 2020 IRP with the MoPSC in June 2022 to reflect,
among other things, the updated scheduled retirement dates of the natural
gas-fired energy centers located in the state of Illinois.

•In April 2022, the MISO released the results of its 2022 capacity auction,
which projected a capacity shortage in the central region of the MISO footprint,
which includes Ameren Missouri's and Ameren Illinois' service territories. The
projected shortage resulted in higher capacity prices for June 2022 through May
2023, and the MISO indicated that the shortage may lead to temporary, controlled
interruptions of service during the summer of 2022 to maintain system
reliability.

•We are observing inflationary pressures on the prices of commodities, labor,
services, materials, and supplies, as well as increasing interest rates. Ameren
Missouri and Ameren Illinois are generally allowed to pass on to customers
prudently incurred costs for fuel, purchased power, and natural gas supply.
Additionally, for certain non-commodity cost changes, the use of trackers,
riders, and formula ratemaking, as applicable, mitigates our exposure. The
inflationary pressures and increasing interest rates could impact our ability to
control costs and/or make substantial investments in our businesses, including
our ability to recover costs and investments, and to earn our allowed ROEs
within frameworks established by our regulators, while maintaining rates that
are affordable to our customers. Based on estimated power prices and customer
demand, the capacity price set by the April 2022 MISO auction, and the amounts
of energy and capacity hedged through IPA procurement events, Ameren Illinois
estimates an increase to purchased power costs for calendar year 2022, compared
to 2021, of approximately $400 million. The actual increase to purchased power
costs will vary due to differences between estimated and realized power prices
as well as customer demand satisfied by Ameren Illinois, which will be affected
by changes in customers' elections to use Ameren Illinois or an alternative
retail electric supplier for their energy needs. An increase to purchased power
costs for calendar year 2023, compared to 2021, is also likely but Ameren
Illinois cannot reasonably estimate the amount of the increase as additional
energy and capacity contracts for 2023 will be entered into as a part of IPA
procurement events
                                       70

later in 2022 and the first half of 2023, as well as pricing determined by the
April 2023 MISO capacity auction. Because of the power procurement riders, the
difference between actual purchased power costs and costs billed to customers in
a given period is deferred as a regulatory asset or liability. These
pass-through costs do not affect Ameren Illinois' net income, as any change in
costs are offset by a corresponding change in revenues. Also, based on the
capacity price set by the April 2022 MISO auction, Ameren Missouri estimates
increases to capacity revenues and purchased power costs for the calendar year
2022, compared to 2021, of approximately $375 million. Ameren Missouri sells
nearly all of its capacity to the MISO and purchases the capacity it needs to
supply its native load sales from the MISO. An increase to capacity revenues and
purchased power costs for calendar year 2023, compared to 2021, is also likely
but Ameren Missouri cannot reasonably estimate the amount of the increases as
capacity pricing for June 2023 through December 2023 will be determined by the
April 2023 MISO capacity auction. Capacity revenues and purchased power costs
are a part of the net energy costs recoverable under the FAC, with 95% of the
variance between net energy costs and the amount set in base rates recovered or
refunded through the FAC.

•Ameren Missouri and Ameren Illinois continue to make infrastructure investments
and expect to seek increases to electric and natural gas rates to recover the
cost of investments and earn an adequate return. Ameren Missouri and Ameren
Illinois will also seek new, or to maintain existing, legislative solutions to
address regulatory lag and to support investment in their utility infrastructure
for the benefit of their customers. Ameren Missouri and Ameren Illinois continue
to face cost recovery pressures, including limited economic growth in their
service territories, increasing inflation, higher cost of debt, economic impacts
of the COVID-19 pandemic, customer conservation efforts, the impacts of
additional customer energy-efficiency programs, and increased customer use of
increasingly cost-effective advancements in innovative energy technologies,
including private generation and energy storage. However, over the long-term, we
expect the decreased demand to be partially offset by increased demand resulting
from increased electrification of the economy and as a means to address
economy-wide CO2 emission concerns. We expect that increased investments,
including expected future investments for environmental compliance, system
reliability improvements, and new generation sources, will result in rate base
and revenue growth but also higher depreciation and financing costs.

Liquidity and Capital Resources



•In February 2022, Ameren Missouri filed an update to its Smart Energy Plan with
the MoPSC, which includes a five-year capital investment overview with a
detailed one-year plan for 2022. The plan is designed to upgrade Ameren
Missouri's electric infrastructure and includes investments that will upgrade
the grid and accommodate more renewable energy. Investments under the plan are
expected to total approximately $8.4 billion over the five-year period from 2022
through 2026, with expenditures largely recoverable under the PISA and the
RESRAM.

•In June 2022, Ameren Missouri filed a notice of change in preferred resource
plan with the MoPSC. The filing includes a 2022 Change to the 2020 IRP, which
the MoPSC may review at its election. In connection with the change, Ameren
revised its goals for reduction of carbon emissions. Ameren is targeting
net-zero carbon emissions by 2045, as well as a 60% reduction by 2030 and an 85%
reduction by 2040 based on 2005 levels. Ameren's goals include both direct
emissions from operations, as well as electricity usage at Ameren buildings,
including other greenhouse gas emissions of methane, nitrous oxide, and sulfur
hexafluoride. Achieving these goals will be dependent on a variety of factors,
including cost-effective advancements in innovative clean energy technologies
and constructive federal and state energy and economic policies. The 2022 Change
to the 2020 IRP includes expanding renewable sources by adding 2,800 MWs of
renewable generation by 2030, 400 MWs of battery storage by 2035, and a total of
4,700 MWs of renewable generation and 800 MWs of battery storage by 2040. These
amounts include 350 MWs of solar generation projects discussed below. The change
also includes adding 1,200 MWs of natural gas-fired combined cycle generation by
2031, with plans to switch to hydrogen fuel and/or blend hydrogen fuel with
natural gas and install carbon capture technology if these technologies become
commercially available at a reasonable cost, adding 1,200 MWs of additional
clean dispatchable generation by 2043, the continued implementation of customer
energy-efficiency programs, and the expectation that Ameren Missouri will seek
and receive NRC approval for an extension of the operating license for the
Callaway Energy Center beyond its current 2044 expiration date. Additionally,
the change includes extending the retirement date of the coal-fired Sioux Energy
Center from 2028 to 2030 in order to ensure reliability during the transition to
clean energy generation, which is subject to the approval of a change in the
asset's depreciable life by the MoPSC in Ameren Missouri's current electric
service regulatory rate review, accelerating the retirement date of the Rush
Island coal-fired energy center to 2025, retiring the Meramec coal-fired energy
center at the end of its useful life in 2022, retiring the generating units at
the Labadie coal-fired energy center at the end of their useful lives (two
generating units by 2036 and the other two by 2042), accelerating the retirement
date of the Venice natural gas-fired energy center to 2029, and retiring Ameren
Missouri's other natural gas-fired energy centers in Illinois by 2040. Ameren
Missouri's plan could be affected by, among other factors: Ameren Missouri's
ability to obtain certificates of convenience and necessity from the MoPSC, and
any other required approvals for the addition of renewable resources, retirement
of energy centers, and new or continued customer energy-efficiency programs; the
ability to enter into build-transfer agreements for renewable generation and
acquire that generation at a reasonable cost; the ability of developers to meet
contractual commitments and timely complete projects, which is dependent upon
the availability of necessary labor, materials, and equipment, including those
that are affected by the disruptions in the global supply chain caused by the
COVID-19 pandemic or government actions, among other things; changes in the

Missouri's ability to use such credits; the cost of wind, solar, and other
renewable generation and storage technologies; the cost of natural gas or
hydrogen CT technologies; changes in environmental regulations, including those
related to CO2 and other greenhouse gas emissions; energy prices and demand; and
Ameren Missouri's ability to obtain necessary rights-of-way, easements, and
transmission interconnection agreements at an acceptable cost and in a timely
fashion. The next integrated resource plan is expected to be filed in September
2023.

•Missouri law allows Missouri electric utility companies to petition the MoPSC
for a financing order to authorize the issuance of securitized utility tariff
bonds to finance the cost of retiring electric generation facilities before the
end of their useful lives, including the repayment of existing debt. In
connection with the planned accelerated retirement of the Rush Island Energy
Center due to the NSR and Clean Air Act Litigation discussed above, Ameren
Missouri expects to seek approval from the MoPSC to finance the costs associated
with the retirement, including the remaining unrecovered net plant balance
associated with the facility, through the issuance of securitized utility tariff
bonds. As such, Ameren Missouri did not request a change in the depreciation
rates related to the Rush Island Energy Center in the electric regulatory rate
review filed in August 2022.

•In February 2022, Ameren Missouri, through a subsidiary, entered into a
build-transfer agreement to acquire, after construction, a 150-MW solar
generation facility, which is expected to be located in southeastern Illinois
and, if approved by the MoPSC, serve customers under Ameren Missouri's Renewable
Solutions Program. In June 2022, Ameren Missouri, through a subsidiary, entered
into a build-transfer agreement to acquire, after construction, a 200-MW solar
generation facility, which is expected to be located in central Missouri and
support Ameren Missouri's compliance with the state of Missouri's requirement of
achieving 15% of retail sales from renewable energy sources, of which 2% must be
derived from solar energy sources. The acquisitions are subject to certain
conditions, including the issuance of certificates of convenience and necessity
by the MoPSC, obtaining MISO transmission interconnection agreements, and
approval by the FERC. In July 2022, Ameren Missouri filed for certificates of
convenience and necessity with the MoPSC for both facilities and expects
decisions by March 2023 and April 2023 for the 200-MW facility and the 150-MW
facility, respectively. Depending on the timing of regulatory approvals and the
impact of potential sourcing issues discussed below, the projects could be
completed as early as the fourth quarter of 2024. Capital expenditures related
to these facilities are not included in Ameren's and Ameren Missouri's expected
capital investments discussed below.

•Ameren Missouri's 2022 Change to the 2020 IRP targets cleaner and more diverse
sources of energy generation, including solar generation. While rights to
acquire the solar facilities discussed above were secured through build-transfer
agreements, supply chain disruptions, including solar panel shortages and
increasing material costs as a result of government tariffs and other factors,
could affect the costs as well as the timing of these projects and other solar
generation projects. The supply of solar panels to the United States was
significantly disrupted as a result of an investigation initiated by the
Department of Commerce in late March 2022, which could result in punitive
tariffs on solar panels imported from four Southeast Asian countries. The
investigation is in response to complaints of Chinese solar manufacturers
shifting solar cells to these countries to avoid tariffs required on imports
from China. The Department of Commerce is required to issue a preliminary
determination within 150 days of its initiation of an investigation, with final
determination taking 300 days or more. Additionally, certain solar panels from
China have been subject to detention by the United States Customs and Border
Protection Agency as a result of the Uyghur Forced Labor Prevention Act that was
passed in December 2021. In June 2022, President Biden authorized the Department
of Energy to use the Defense Production Act to rapidly expand American
manufacturing of five critical clean energy technologies, including solar panel
components. President Biden also took executive action to temporarily lift
certain tariffs on solar panels imported from the four Southeast Asian countries
under investigation by the Department of Commerce for 24 months in order to
allow the United States access to a sufficient supply of solar panels to meet
electricity generation needs while domestic manufacturing scales up. Any future
tariffs or other outcomes resulting from the investigation by the Department of
Commerce or actions by the United States Customs and Border Protection Agency
could affect the cost and the availability of solar panels and the timing and
amount of Ameren Missouri's estimated capital expenditures associated with solar
generation investments.

•Through 2026, we expect to make significant capital expenditures to improve our
electric and natural gas utility infrastructure, with a major portion directed
to our transmission and distribution systems. We estimate that we will invest up
to $18.0 billion (Ameren Missouri - up to $9.2 billion; Ameren Illinois - up to
$8.6 billion; ATXI - up to $0.2 billion) of capital expenditures during the
period from 2022 through 2026. These planned investments are based on the
assumption of continued constructive regulatory frameworks. Ameren's and Ameren
Missouri's estimates exclude renewable generation investment opportunities of
800 MWs by 2026, which are included in Ameren Missouri's 2022 Change to the 2020
IRP, and investment opportunities that may be approved by the MISO to address
reliability concerns in connection with the planned accelerated retirement of
the Rush Island Energy Center. These investment opportunities may be incremental
to or partially replace other expenditures included in the 2022 through 2026
estimates above.

•In 2021, the MISO issued a report outlining a preliminary long-range
transmission planning roadmap of projects through 2039, which considers the
rapidly changing generation mix within MISO resulting from significant additions
of renewable generation, actual and expected generation plant closures, and
state mandates or goals for clean energy or carbon emissions reductions. In July
2022, the MISO approved the first tranche of projects under the first phase of
the roadmap. A portion of these projects were assigned to various utilities, of
which Ameren was awarded projects that are estimated to cost approximately
$1.8 billion, based on MISO's cost estimate.

The MISO is expected to initiate requests for proposals for the remaining
projects included in the first tranche, which are expected to be awarded between
mid-2023 and mid-2024. These investment opportunities may be incremental to or
partially replace other expenditures included in the 2022 through 2026 estimates
discussed above. In July 2022, a group of industrial customers filed a complaint
with the FERC, challenging provisions of a MISO tariff that exclude regional
transmission projects from the MISO's competitive bid process based on state
laws related to the right of first refusal, which provide an incumbent utility
the right to build, maintain, and own transmission lines located within its
service territory. The complaint seeks to require MISO to revise its tariff to
prohibit the application of state laws related to the right of first refusal in
the MISO's long-range transmission planning and require projects to be bid on a
competitive basis, to the maximum extent possible. It also is asking for refunds
related to any costs under the tariff that would not comply with the
sought-after revisions. The FERC is under no deadline to issue an order.

•In July 2022, an Illinois law prohibiting the state's oversight of certain
electric utilities' choice of RTO membership ceased to be effective. Given the
change in law and the high prices resulting from MISO's 2022 capacity auction,
the ICC issued an order requiring Ameren Illinois to perform a cost benefit
study of continued participation in the MISO compared to participation in PJM
Interconnection LLC, another RTO. The cost benefit study will examine the
impacts of participation in each RTO, including reliability, resiliency,
affordability, and environmental impacts, among other things, for a period of
five to 10 years beginning June 2024. The ICC order requires Ameren Illinois to
file the study by July 2023. A 30-day comment period will follow. The ICC is
under no obligation to issue an order in this matter.

•Environmental regulations, including those related to CO2 emissions, or other
actions taken by the EPA or state regulators, or requirements that may result
from the NSR and Clean Air Act Litigation discussed in Note 9 - Commitments and
Contingencies under Part I, Item 1, of this report, could result in significant
increases in capital expenditures and operating costs. Regulations enacted by a
prior federal administration can be reviewed and repealed, and replacement or
alternative regulations can be proposed or adopted by the current federal
administration including the EPA. The ultimate implementation of any of these
regulations, as well as the timing of any such implementation, is uncertain.
However, the individual or combined effects of existing and new environmental
regulations could result in significant capital expenditures, increased
operating costs, or the closure or alteration of some of Ameren Missouri's coal
and natural gas-fired energy centers. Ameren Missouri's capital expenditures are
subject to MoPSC prudence reviews, which could result in cost disallowances as
well as regulatory lag. The cost of Ameren Illinois' purchased power and natural
gas purchased for resale could increase. However, Ameren Illinois expects that
these costs would be recovered from customers with no material adverse effect on
its results of operations, financial position, or liquidity. Ameren's and Ameren
Missouri's earnings could benefit from increased investment to comply with
environmental regulations if those investments are reflected and recovered on a
timely basis in customer rates.

•The Ameren Companies have multiyear credit agreements that cumulatively provide
$2.3 billion of credit through December 2025, subject to a 364-day repayment
term for Ameren Missouri and Ameren Illinois, with the option to seek
incremental commitments to increase the cumulative credit provided to
$2.7 billion. See Note 3 - Short-term Debt and Liquidity under Part I, Item 1,
of this report and Note 4 - Short-term Debt and Liquidity under Part II, Item 8,
in the Form 10-K for additional information regarding the Credit Agreements. By
the end of 2022, $55 million, $400 million, and $50 million of long-term debt
obligations are due to mature at Ameren Missouri, Ameren Illinois, and ATXI,
respectively. Ameren, Ameren Missouri, and Ameren Illinois believe that their
liquidity is adequate given their expected operating cash flows, capital
expenditures, and financing plans. To date, the Ameren Companies have been able
to access the capital markets on reasonable terms when needed. However, there
can be no assurance that significant changes in economic conditions, disruptions
in the capital and credit markets, or other unforeseen events will not
materially affect their ability to execute their expected operating, capital, or
financing plans.

•Ameren expects its cash used for currently planned capital expenditures and
dividends to exceed cash provided by operating activities over the next several
years. As part of its funding plan for capital expenditures, Ameren is using
newly issued shares of common stock, rather than market-purchased shares, to
satisfy requirements under the DRPlus and employee benefit plans and expects to
continue to do so through at least 2026. Ameren expects these issuances to
provide equity of about $100 million annually. In addition, in 2021, Ameren
established an ATM program under which Ameren may offer and sell from time to
time up to $750 million of its common stock, which includes the ability to enter
into forward sales agreements, subject to market conditions and other factors.
Ameren has entered into multiple forward sale agreements under the ATM program
with various counterparties relating to 5.8 million shares of common stock. As
of June 30, 2022, Ameren could have settled the forward sale agreements with
physical delivery of 5.6 million shares of common stock to the respective
counterparties in exchange for cash of $500 million. As of June 30, 2022, Ameren
had approximately $90 million of common stock available under the ATM program,
which takes into account the forward sale agreements in effect as of June 30,
2022. For additional information regarding outstanding forward sale agreements,
including settlement dates, see Note 4 - Long-Term Debt and Liquidity under
Part I, Item 1, of this report. Ameren expects to settle approximately
$300 million of the forward sale agreements by December 31, 2022. Ameren plans
to issue approximately $300 million of equity each year from 2022 to 2026 in
addition to issuances under the DRPlus and employee benefit plans. Ameren
expects its equity to total capitalization ratio to be approximately 45% through
December 31, 2026, with the long-term intent to support solid investment-grade
credit ratings. Ameren Missouri and Ameren Illinois expect to fund cash flow
needs through debt issuances, adjustments of dividends to Ameren (parent),
and/or capital contributions from Ameren (parent).

•As of June 30, 2022, Ameren had $146 million in tax benefits from federal and
state income tax credit carryforwards and $38 million in tax benefits from
federal and state net operating loss carryforwards, which will be utilized in
future periods. Ameren expects federal income tax payments at the required
minimum levels from 2022 to 2026 resulting from the anticipated use of existing
production tax credits generated by Ameren Missouri's High Prairie Renewable and
Atchison Renewable energy centers, existing tax net operating losses, tax credit
carryforwards, tax overpayments, and outstanding refunds.

The above items could have a material impact on our results of operations,
financial position, and liquidity. Additionally, in the ordinary course of
business, we evaluate strategies to enhance our results of operations, financial
position, and liquidity. These strategies may include acquisitions,
divestitures, opportunities to reduce costs or increase revenues, and other
strategic initiatives to increase Ameren's shareholder value. We are unable to
predict which, if any, of these initiatives will be executed. The execution of
these initiatives may have a material impact on our future results of
operations, financial position, or liquidity.
