Forward Looking Statements



This Quarterly Report on Form 10-Q contains information and statements that are
considered "forward-looking statements" within the meaning of Section 27A of the
Securities Act of 1933, as amended, and Section 21E of the Securities Exchange
Act of 1934, as amended. Such forward-looking statements are based on
management's current expectations and beliefs concerning future developments and
their potential effects on the Company, and include, without limitation,
statements about the Company's plans, strategies, goals, objectives,
expectations, or consequences of statements about the future performance,
operations, products and services of the Company and its subsidiaries, as well
as statements about the Company's expectations regarding revenue and asset
growth, financial performance and profitability, loan and deposit growth, yields
and returns, loan diversification and credit management, products and services,
shareholder value creation and the impact of the SCBH acquisition and other
acquisitions. Forward-looking statements are typically identified with the use
of terms such as "may," "might," "will," "would," "should," "expect," "plan,"
"anticipate," "believe," "estimate," "predict," "potential," "could,"
"continue," "intend," and the negative and other variations of these terms and
similar words and expressions, although some forward-looking statements may be
expressed differently. Forward-looking statements are inherently subject to
risks and uncertainties and our ability to predict results or the actual effect
of future plans or strategies is inherently uncertain. You should be aware that
our actual results could differ materially from those contained in the
forward-looking statements.

The COVID-19 pandemic is adversely affecting us, our customers, counterparties,
employees, and third-party service providers, and the ultimate extent of the
impacts on our business, financial position, results of operations, liquidity,
and prospects is uncertain. Continued deterioration in general business and
economic conditions, including further increases in unemployment rates, or
turbulence in domestic or global financial markets could adversely affect our
revenues and the values of our assets and liabilities, reduce the availability
of funding, lead to a tightening of credit, and further increase stock price
volatility. In addition, changes to statutes, regulations, or regulatory
policies or practices as a result of, or in response to COVID-19, could affect
us in substantial and unpredictable ways.  Other factors that could cause or
contribute to such differences include, but are not limited to: our ability to
efficiently integrate acquisitions, including the SCBH acquisition, into our
operations, retain the customers of these businesses and grow the acquired
operations; credit risk; changes in the appraised valuation of real estate
securing impaired loans; our ability to recover our investment in loans;
fluctuations in the fair value of collateral underlying loans; outcomes of
litigation and other contingencies; exposure to general and local economic
conditions; risks associated with rapid increases or decreases in prevailing
interest rates; changes in business prospects that could impact goodwill
estimates and assumptions; consolidation within the banking industry;
competition from banks and other financial institutions; our ability to attract
and retain relationship officers and other key personnel; burdens imposed by
federal and state regulation; changes in regulatory requirements; changes in
accounting policies and practices or accounting standards, including ASU 2016-13
(Topic 326), "Measurement of Credit Losses on Financial Instruments," commonly
referenced as CECL model, which has changed how we estimate credit losses;
uncertainty regarding the future of LIBOR; natural disasters, war or terrorist
activities, or pandemics, or the outbreak of COVID-19 or similar outbreaks, and
their effects on economic and business environments in which we operate;
increased unemployment rates and defaults as a result of the economic
disruptions caused by COVID-19; the impact of governmental orders issued in
response to COVID-19; and other risks discussed under the caption "Risk Factors"
under Part 1, Item 1A of our 2019 Annual Report on Form 10-K and Item 1A of Part
II of our Quarterly Report on Form 10-Q for the quarters ended March 31, 2020
and June 30, 2020, and other reports filed with the SEC, all of which could
cause the Company's actual results to differ from those set forth in the
forward-looking statements.

Readers are cautioned not to place undue reliance on our forward-looking
statements, which reflect management's analysis and expectations only as of the
date of such statements. Forward-looking statements speak only as of the date
they are made, and the Company does not intend, and undertakes no obligation, to
publicly revise or update forward-looking statements after the date of this
report, whether as a result of new information, future events or otherwise,
except as required by federal securities law. You should understand that it is
not possible to predict or

Introduction



The following discussion describes the significant changes to the financial
condition of the Company that have occurred during the first nine months of 2020
compared to the financial condition as of December 31, 2019. In addition, this
discussion summarizes the significant factors affecting the results of
operations, liquidity and cash flows of the Company for the three and nine
months ended September 30, 2020, compared to the same periods in 2019. This
discussion should be read in conjunction with the accompanying condensed
consolidated financial statements included in this report and our Annual Report
on Form 10-K for the year ended December 31, 2019.

COVID-19 Pandemic



On January 31, 2020, the Secretary of Health and Human Services declared a
public health emergency due to the global outbreak of a new strain of
coronavirus (COVID-19). On March 13, 2020, the President of the United States
proclaimed the COVID-19 as a national emergency, following the World Health
Organization's categorization of the outbreak as a pandemic. COVID-19 continues
to aggressively spread globally, including throughout the United States. The
pandemic and resulting travel bans, closure of non-essential businesses, social
distancing measures and government responses across the country have had a
profound impact on the global economy, financial markets and how business has
been conducted across all industries and have affected many of the Company's
customers and clients. To the extent the economic impacts of the pandemic
continue for a prolonged period and conditions stagnate or worsen, our provision
for credit losses, noninterest income, and profitability may be adversely
affected.

The Company has taken proactive and disciplined steps to promote the safety and
overall wellbeing of its associates, customers and stakeholders, as well as to
manage its financial performance. Steps taken include activation of the
Company's business continuity plan, formation of a communication and action task
force, cost containment measures, restrictions on business travel, conversion of
in-person meetings to virtual or with restrictions in certain markets, a
work-from-home mandate, branch lobby access restrictions, and multiple safety
and social distancing protocols. The Company has also worked with its customers
to implement appropriate loan deferral strategies in certain circumstances.

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security ("CARES")
Act was signed into law. The CARES Act contains provisions to assist individuals
and businesses, including the SBA's Paycheck Protection Program ("PPP"). The PPP
provided $349 billion in guaranteed loans that are forgivable if certain
requirements are met. On April 24, 2020, an additional $310 billion was added to
the PPP program. The CARES Act included a provision that allowed depository
institutions the option to defer adoption of the CECL standard to the earlier of
(1) the end of the COVID-19 national emergency or (2) December 31, 2020. The
Company did not elect the deferral option.

On April 7, 2020, the U.S. banking agencies issued an Interagency Statement on
Loan Modifications and Reporting for Financial Institutions Working with
Customers Affected by the Coronavirus (Revised). The statement describes
accounting for COVID-19-related loan modifications, including clarifying the
interaction between current accounting rules and the temporary relief provided
by the CARES Act. The statement also encourages institutions to work
constructively with borrowers affected by COVID-19 and states the agencies will
not criticize supervised institutions for prudent loan modifications. Both the
CARES Act and the interagency statement provide relief from the accounting and
reporting implications of troubled debt restructurings. The Company has
implemented short-term deferral programs allowing customers to primarily defer
payments for up to 90 days. As of September 30, 2020, loans of $139.4 million
were in a deferral status of which $86.1 million represent second round
deferrals. The deferral period expires in the fourth quarter 2020 for
approximately 99% of loans in a deferral status.

                                       29
--------------------------------------------------------------------------------

Critical Accounting Policies



The following accounting policies are considered most critical to the
understanding of the Company's financial condition and results of operations.
These critical accounting policies require management's most difficult,
subjective and complex judgments about matters that are inherently uncertain.
Because these estimates and judgments are based on current circumstances, they
may change over time or prove to be inaccurate based on actual experience. If
different assumptions or conditions were to prevail, and depending upon the
severity of such changes, the possibility of a materially different financial
condition and/or results of operations could reasonably be expected. The impact
and any associated risks related to our critical accounting policies on our
business operations are discussed throughout "Management's Discussion and
Analysis of Financial Condition and Results of Operations," where such policies
affect our reported and expected financial results. For a detailed discussion on
the application of these and other accounting policies, see the Company's Annual
Report on Form 10-K for the year ended December 31, 2019.

The Company has prepared the consolidated financial information in this report
in accordance with GAAP. The Company makes estimates and assumptions that affect
the reported amount of assets and liabilities, disclosure of contingent assets
and liabilities at the date of the consolidated financial statements, and the
reported amounts of revenue and expenses during the reporting period. Such
estimates include the valuation of loans, goodwill, intangible assets, and other
long-lived assets, along with assumptions used in the calculation of income
taxes, among others. These estimates and assumptions are based on management's
best estimates and judgment. Management evaluates its estimates and assumptions
on an ongoing basis using loss experience and other factors, including the
current economic environment, which management believes to be reasonable under
the circumstances. We adjust such estimates and assumptions when facts and
circumstances dictate. The three and nine months ended September 30, 2020 were
characterized by heightened uncertainty due to the COVID-19 pandemic which could
impact estimates and assumptions made by management. As future events and their
effects cannot be determined with precision, actual results could differ
significantly from these estimates. Changes in estimates resulting from
continuing changes in the economic environment will be reflected in the
financial statement in future periods. There can be no assurances that actual
results will not differ from those estimates.

Allowance for Credit Losses



On January 1, 2020, the Company adopted Accounting Standard Update 2016-13
"Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses
on Financial Instruments." This standard, referred to as CECL, requires an
estimate of lifetime expected credit losses on certain financial assets measured
at amortized cost.

The Company maintains separate allowances for funded loans, unfunded loans, and
held-to-maturity securities, collectively the ACL. The ACL is a valuation
account to adjust the cost basis to the amount expected to be collected, based
on management's estimate of experience, current conditions, and reasonable and
supportable forecasts. For purposes of determining the allowance for funded and
unfunded loans, the portfolios are segregated into pools that share similar risk
characteristics that are then further segregated by credit grades. Loans that do
not share similar risk characteristics are evaluated on an individual basis and
are not included in the collective evaluation. The Company estimates the amount
of the allowance based on loan loss experience, adjusted for current and
forecasted economic conditions, including unemployment, changes in GDP, and
commercial and residential real estate prices. The Company's forecast of
economic conditions uses internal and external information and considers a
weighted average of a baseline, upside, and downside scenarios. Because economic
conditions can change and are difficult to predict, the anticipated amount of
estimated loan defaults and losses, and therefore the adequacy of the allowance,
could change significantly and have a direct impact on the Company's credit
costs.

Goodwill and Other Intangible Assets



The Company completes a goodwill impairment test in the fourth quarter each year
or whenever events or changes in circumstances indicate the Company may not be
able to recover the goodwill, or intangible assets, respective carrying amount.
The impairment test involves the use of various estimates and assumptions.
Management believes the estimates and assumptions utilized are reasonable.
                                       30
--------------------------------------------------------------------------------


Goodwill is evaluated for impairment at the reporting unit level. Reporting
units are defined as the same level as, or one level below, an operating
segment. An operating segment is a component of a business for which separate
financial information is available that management regularly evaluates in
deciding how to allocate resources and assess performance. The Company has one
reporting unit and one operating segment.

Potential impairments to goodwill must first be identified by performing a
qualitative assessment that evaluates relevant events or circumstances to
determine whether it is more likely than not the fair value of a reporting unit
is less than its carrying amount. If this test indicates it is more likely than
not that goodwill has been impaired, then a quantitative impairment test is
completed. The quantitative impairment test calculates the fair value of the
reporting unit and compares it with its carrying amount, including goodwill. If
the carrying amount of goodwill exceeds its implied fair market value, an
impairment loss is recognized. That loss is equal to the carrying amount of
goodwill that is in excess of its implied fair market value.

Intangible assets other than goodwill, such as core deposit intangibles,
determined to have finite lives are amortized over their estimated remaining
useful lives. These assets are reviewed for impairment whenever events or
changes in circumstances indicate the carrying amount of an asset may not be
recoverable. Recoverability of assets to be held and used is measured by a
comparison of the carrying amount of an asset to estimated undiscounted future
cash flows expected to be generated by the asset. If the carrying amount of an
asset exceeds its estimated future cash flows, an impairment charge is
recognized by the amount by which the carrying amount of the asset exceeds the
fair value of the asset.

As of September 30, 2020, while the Company has not recognized an impairment,
there can be no assurance that prolonged market volatility resulting from the
COVID-19 pandemic will not result in impairments to goodwill or other
intangibles in future periods.

Participation in the PPP has impacted the Company's financial metrics in the
three and nine months ended September 30, 2020. Loan and deposit growth,
earnings per share, and return on assets all increased due to the PPP.
Conversely, net interest margin, the allowance coverage ratio, the leverage
ratio and the ratio of tangible common equity to tangible assets all decreased.
Since the PPP loans are guaranteed by the SBA, CET1, Tier 1 and total risk-based
capital are not impacted by the PPP loan balances.

•For the three and nine months ended September 30, 2020, the Company had net
income of $18.0 million and $45.5 million, respectively, compared to $29.1
million and $63.6 million, respectively, for the prior year periods. Earnings
per diluted share for the three and nine months ended September 30, 2020 was
$0.68 and $1.73, respectively, and $1.08 and $2.45, for the same respective
periods in 2019. Net income and earnings per share for the three and nine months
ended September 30, 2020 were impacted from $14.1 million and $55.9 million,
respectively, on a pretax basis ($10.6 million and $42.1 million, respectively,
after tax), of provision for credit losses. The increase in the provision for
credit losses for the three months ending September 30, 2020 was primarily due
to an increase in individual reserves and qualitative reserves established for
certain higher risk areas, including hospitality and loans that have received
principal and interest deferrals partially offset by improvements in economic
forecasts. Deterioration in the economic forecasts during the first two quarters
of 2020 primarily contributed to the increase for the nine months ended
September 30, 2020. Net income and earnings per share for the three months ended
September 30, 2020 and 2019 were impacted by $1.6 million and $0.4 million,
respectively, on a pretax basis ($1.2 million and $0.3 million, respectively,
after tax), of merger-related expenses. For the nine months ended September 30,
2020 and 2019 net income and earnings per share were impacted by $1.6 million
and $18.0 million, respectively, on a pretax basis ($1.2 million and $14.0
million, respectively, after tax), of merger-related expenses.

•Net interest income for the three and nine months ended September 30, 2020
increased $0.3 million and $15.5 million, respectively, over the prior year
periods primarily from reductions in rates on interest-bearing liabilities.
Higher loan volumes, due to PPP loans in the three and nine month comparisons,
and due to the Trinity acquisition in the nine month comparison, were offset by
reductions in loan yields of 139 basis points and 102 basis points for the three
and nine month comparisons, respectively.

The tax-equivalent net interest margin was 3.29% and 3.52% for the three and
nine months ended September 30, 2020, respectively, compared to 3.81% and 3.85%
in the prior year periods, respectively. The net interest margin was impacted by
the decline in short-term rates as approximately 60% of the Company's loan
portfolio (excluding PPP) has variable rates, with most indexed to one-month
LIBOR that has declined significantly over the past year. Average one-month
LIBOR was 0.16% and 0.64% in the three and nine months ended September 30, 2020,
respectively, compared to 2.18% and 2.37% in the comparable prior year periods,
respectively.

--------------------------------------------------------------------------------


•Noninterest income for the three and nine months ended September 30, 2020
decreased $0.9 million and increased $1.2 million, respectively, compared to the
prior year periods. For the third quarter 2020, the increase in deposit balances
provided more earnings credits to business customers on analysis, resulting in
lower service charge income compared to the prior year periods. The increase in
noninterest income for the nine months ended September 30, 2020 compared to the
prior year period was primarily due to the acquisition of Trinity in March 2019.

•Noninterest expense increased $1.3 million, or 3%, for the third quarter 2020,
compared to the same period in 2019. The increase was primarily due to
merger-related expenses. For the nine months ended September 30, 2020,
noninterest expense decreased $11.0 million, or 9%, from the prior year period
primarily due to higher merger-related expenses in the prior year period,
partially offset by an increase in employee compensation from merit increases
and the acquisition of Trinity.

Balance sheet highlights:



•Loans - Total loans grew $812.0 million from December 31, 2019, or 15.3%, to
$6.1 billion as of September 30, 2020. Growth in the loan portfolio was
primarily driven by PPP loans.
•Deposits - Total deposits grew $905.2 million, or 15.7%, to $6.7 billion as of
September 30, 2020 primarily due to PPP related deposits, government stimulus
checks and organic growth. Noninterest deposit accounts represented 28.9% of
total deposits at September 30, 2020, and the loan to deposit ratio was 91.8%.
•Asset quality - The allowance for credit losses on loans to total loans
increased to 2.01% at September 30, 2020 from 0.81% at December 31, 2019.
Nonperforming assets to total assets was 0.53% at September 30, 2020 compared to
0.45% at December 31, 2019.
•Subordinated notes - In the second quarter 2020, EFSC issued $63.3 million of
5.75% fixed-to-floating rate subordinated notes due in 2030. The notes are
callable beginning in 2025 and are included in tier 2 capital.
•Shareholders' equity - Total shareholders' equity was $882.3 million and the
tangible common equity to tangible assets ratio1 was 7.99% at September 30, 2020
compared to 8.89% at December 31, 2019. Balance sheet growth from the PPP was
the primary cause of the decline in the tangible common equity to tangible
assets ratio. Bank regulatory capital ratios remain "well-capitalized," with a
common equity tier 1 ratio of 12.0% and a total risk-based capital ratio of
13.3%.

(1) Change in volume multiplied by yield/rate of prior period.
(2) Change in yield/rate multiplied by volume of prior period.
(3) Nontaxable income is presented on a tax equivalent basis.
NOTE: The change in interest due to both rate and volume has been allocated to
rate and volume changes in proportion to the relationship of the absolute dollar
amounts of the change in each.

Net interest income (on a tax equivalent basis) for the three and nine months
ended September 30, 2020 increased 1% and 9%, respectively, over the prior year
periods primarily from reductions in rates on interest-bearing liabilities
offset by a decline in the yield on earning assets. Loan yields declined 139
basis points and 102 basis points for the three and nine months ended September
30, 2020, respectively, compared to the comparable prior year periods primarily
due to LIBOR resets as well as lower rates on new and renewing loans in addition
to a lower yield on PPP loans. Higher average loan balances from PPP loans and
an increase in short-term investment balances also negatively impacted the yield
on earning assets.
The tax-equivalent net interest margin was 3.29% and 3.52% for the three and
nine months ended September 30, 2020, respectively, compared to 3.81% and 3.85%
in the prior year periods, respectively. The net interest margin was impacted by
the decline in short-term rates as approximately 60% of the Company's loan
portfolio (excluding PPP) has variable rates, with most indexed to one-month
LIBOR that has declined significantly over the past year. Average one-month
LIBOR was 0.16% and 0.64% in the three and nine months ended September 30, 2020,
respectively, compared to 2.18% and 2.37% in the comparable prior year periods,
respectively.

The Company responded to interest rate trends by reducing the cost of certain
managed money market and interest-bearing transaction accounts. Net interest
income and margin both benefited from an 89 basis point decrease in the rate
paid on interest-bearing deposits in the third quarter 2020 compared to the
third quarter 2019. The rate on interest-bearing deposits for the nine months
ended September 30, 2020 declined 73 basis points compared to the prior-year
period. In addition, EFSC's subordinated debt issuance in the second quarter of
2020 reduced net interest margin by two basis points for the nine months ended
September 30, 2020.

Noninterest income decreased $0.9 million, or 7%, for the three months ended
September 30, 2020, compared to the same period in 2019. The increase in deposit
account balances provided more earnings credits to business customers, resulting
in lower service charge income compared to the prior year quarter. The Company's
tax credit income decreased in the current quarter over the prior year period
primarily due to the timing on projects.

Noninterest income increased $1.2 million, or 4%, for the nine months ended
September 30, 2020, compared to the same period in 2019. Tax credit income
increased partially due to fair value adjustments on tax credits. The fair value
of these projects increased due to a decline in the LIBOR component of the
discount rate. Miscellaneous income increased $1.4 million in 2020 over 2019 due
primarily to an increase in swap fee income and growth in mortgage revenue.

Noninterest expense increased $1.3 million, or 3%, for the third quarter 2020,
compared to the same period in 2019. The increase from the prior year period was
primarily impacted by merger-related expenses. For the nine months ended
September 30, 2020, noninterest expense decreased $11.0 million, or 9%, from the
prior year period primarily due to higher merger-related expenses in the prior
year period, partially offset by an increase in employee compensation from merit
increases and the acquisition of Trinity.

Efficiency gains primarily from growth in net interest income and managed
increases in noninterest expense have resulted in continued improvements to the
Company's core efficiency ratio. The core efficiency ratio was 51.0% for the
nine months ended September 30, 2020 compared to 53.0% for the same period in
2019.
