Associated Banc-Corp Reports First Quarter 2020 Earnings of $0.27 Per Common Share,

or $0.28 Per Common Share Excluding $2 million in Acquisition Related Costs¹ 

GREEN BAY, Wis. -- April 23, 2020 -- Associated Banc-Corp (NYSE: ASB) ("Associated" or "Company") today reported net income available to common equity ("earnings") of $42 million, or $0.27 per common share for the quarter ended March 31, 2020. Excluding acquisition related costs, the Company reported earnings of $43 million, or $0.28 per common share. These amounts compare to net income available to common equity of $83 million, or $0.50 per common share for the quarter ended March 31, 2019.

“The past two months have been one of the most extraordinary periods in this country’s history. The coronavirus pandemic has presented many challenges, both personal and economic, and we at Associated Bank are committed to helping our customers and communities through this difficult time," said President and CEO Philip B. Flynn. "We have taken action to help our colleagues and customers stay safe and we have contributed to relief efforts in our communities. Associated Bank has strong capital and liquidity and we will continue to help our customers through our COVID-19 Relief Program, which includes suspension of certain fees and loan payment deferrals, and through participation in federal initiatives like the Paycheck Protection Program. Standing together with our customers and communities, we will make it through this turbulent period, and we will be part of the economic recovery that will surely follow."

See page 8 of the attached tables for a reconciliation of GAAP financial measures to non-GAAP financial measures which exclude acquisition and restructuring related costs.

Loans

First quarter 2020 average loans of $23.3 billion were up 1%, or $205 million from the same period last year, and were up 2%, or $525 million from fourth quarter 2019. The increase from the fourth quarter was driven in part by the First Staunton acquisition which closed in February and by customers drawing on lines of credit in March in response to the pandemic. With respect to first quarter average balances by loan category:

• Commercial real estate lending increased $212 million from the same period last year and $135 million from the fourth quarter 2019 to $5.3 billion. The change was largely due to increased construction loans and funded term debt.

• Commercial and business lending was essentially flat compared to the same period last year and increased $172 million from the fourth quarter 2019 to $8.4 billion. The increase from the fourth quarter was driven by power & utilities and general commercial lending.

• Consumer lending was $9.6 billion, down $10 million from the first quarter 2019 and up $219 million from the fourth quarter 2019.

First quarter 2020 period-end loans of $24.4 billion were up 5%, or $1.2 billion from the same period last year, and were up 7%, or $1.5 billion from fourth quarter 2019. Similar to the changes in average balances, the period-end increases were driven by the First Staunton acquisition and pandemic response. With respect to first quarter period-end balances by loan category:

• Commercial and business lending increased $939 million from the same period last year, and $1.2 billion from the fourth quarter 2019 to $9.5 billion.

• Commercial real estate lending increased $500 million from the same period last year, and $367 million from the fourth quarter 2019 to $5.6 billion. The change was largely due to increased construction loans and funded term debt.

• Consumer lending was $9.3 billion, down $221 million from first quarter 2019 and down $16 million from the fourth quarter 2019.

On April 3, the Company began accepting loan applications under the Small Business Administration's Paycheck Protection Program. This initiative was created through the Coronavirus Aid, Relief, and Economic Security Act and is intended to support small business with loans to cover payroll and other employee expenses for companies impacted by the pandemic. As of April 21, the Company had funded over 3,600 loans for nearly $900 million under this program.

Deposits

First quarter 2020 average deposits of $24.3 billion were down $264 million, or 1% from the same period last year and were up $189 million compared to the fourth quarter. The decrease from the first quarter of 2019 reflects the Company's balance sheet repositioning strategy of selling lower-yielding securities and reducing certain higher-cost, non-core customer funding from time deposits, network transaction deposits and money market accounts in 2019. The increase from the fourth quarter was driven by the First Staunton acquisition and by customers building cash in March in response to the pandemic.

With respect to first quarter 2020 average balances by deposit category:

• Savings increased $770 million from the same period last year and increased $155 million from the fourth quarter to $2.9 billion.

• Interest-bearing demand deposits increased $568 million from the same period last year and increased $169 million from the fourth quarter to $5.3 billion.

• Noninterest-bearing demand deposits increased $524 million from the same period last year and increased $36 million from the fourth quarter to $5.5 billion.

• Time deposits decreased $486 million from the same period last year and decreased $111 million from the fourth quarter to $2.6 billion.

• Network transaction deposits decreased $791 million from the same period last year and decreased $5 million from the fourth quarter to $1.4 billion.

• Money market deposits decreased $850 million from the same period last year and decreased $56 million from the fourth quarter to $6.5 billion.

First quarter 2020 period-end deposits of $25.7 billion were up $129 million, or 1% from the same period last year and were up $1.9 billion compared to the fourth quarter. Core funding made up 58% of deposit balances as of March 31, 2020.

With respect to first quarter 2020 period-end balances by deposit category:

• Savings increased $817 million from the same period last year and increased $298 million from the fourth quarter to $3.0 billion.

• Noninterest-bearing demand deposits increased $773 million from the same period last year and increased $657 million from the fourth quarter to $6.1 billion.

• Interest-bearing demand deposits increased $944 million from the same period last year and increased $840 million from the fourth quarter to $6.2 billion.

• Time deposits decreased $1.1 billion from the same period last year and increased $11 million from the fourth quarter to $2.6 billion.

• Money market deposits decreased $1.3 billion from the same period last year and increased $77 million from the fourth quarter to $7.7 billion.

• Network transaction deposits (included in money market and interest-bearing deposits) decreased $472 million from the same period last year and increased $396 million from the fourth quarter to $1.7 billion.

The increases in net interest income and net interest margin from the fourth quarter are due to reductions in the Company's deposit pricing and elevated LIBOR - Fed Funds spread in the first quarter.

• The average yield on total earning assets for the first quarter of 2020 decreased 44 basis points from the same period last year to 3.67% and decreased 11 basis points from the prior quarter.

As a result of implementing the Current Expected Credit Loss accounting standard, the Company incurred an after-tax charge of $98 million which decreased the opening equity balance as of January 1, 2020.

• Potential problem loans of $234 million were down $7 million, or 3%, from the same period last year but up $73 million, or 45%, from the prior quarter.

Numbers may not sum due to rounding.

A corresponding after tax decrease to common equity of $98 million was recorded along with a deferred tax asset of $33 million resulting in a net decrease to accrued expenses and other liabilities of $14 million. Prior periods were unadjusted due to the modified retrospective application of ASU 2016-13.

Numbers may not sum due to rounding.

(a) The ratio tangible common equity to tangible assets excludes goodwill and other intangible assets, net. This financial measure has been included as it is considered to be a critical metric with which to analyze and evaluate financial condition and capital strength.

(b) These financial measures have been included as they provide meaningful supplemental information to assess trends in the Corporation’s results of operations.

(c) Includes trust, asset management, brokerage, and annuity fees.

(d) This is a non-GAAP financial measure. Management believes these measures are meaningful because they reflect adjustments commonly made by management, investors, regulators, and analysts to evaluate the adequacy of earnings per common share and provide greater understanding of ongoing operations and enhanced comparability of results with prior periods.

(e) These capital measurements are used by management, regulators, investors, and analysts to assess, monitor and compare the quality and composition of our capital with the capital of other financial services companies.

(f) The efficiency ratio as defined by the Federal Reserve guidance is noninterest expense (which includes the provision for unfunded commitments) divided by the sum of net interest income plus noninterest income, excluding investment securities gains / losses, net. The fully tax-equivalent efficiency ratio is noninterest expense (which includes the provision for unfunded commitments), excluding other intangible amortization, divided by the sum of fully tax-equivalent net interest income plus noninterest income, excluding investment securities gains / losses, net. The adjusted efficiency ratio is noninterest expense, which excludes the provision for unfunded commitments, other intangible amortization, and acquisition related costs divided by the sum of fully tax-equivalent net interest income plus noninterest income, excluding investment securities gains / losses, net and acquisition related costs. Management believes the adjusted efficiency ratio is a meaningful measure as it enhances the comparability of net interest income arising from taxable and tax-exempt sources and provides a better measure as to how well the Corporation is managing its expenses by adjusting for acquisition related costs and provision for unfunded commitments.

(g) Diluted earnings and per share data presented after-tax.
