Associated Banc-Corp Reports First Quarter 2019 Earnings of $0.50 Per Common Share,

Earnings per share up 25% from the prior year

GREEN BAY, Wis. -- April 25, 2019 -- Associated Banc-Corp (NYSE: ASB) ("Associated" or "Company") today reported net income available to common equity ("earnings") of $83 million, or $0.50 per common share for the quarter ended March 31, 2019. These amounts compare to net income available to common equity of $67 million, or $0.40 per common share for the quarter ended March 31, 2018.

“We were pleased with our commercial and business lending results in the quarter as we had solid growth in our general commercial line and across most of our specialty lending verticals. This growth, coupled with effective cost controls and improving fee income, helped drive a 25% increase in earnings per share compared to the first quarter of 2018," said President and CEO Philip B. Flynn. "We remain optimistic for the remainder of 2019. We expect continued growth in our C&I portfolio and anticipate that our commercial real estate book will begin to ramp up in the second half of the year. Additionally, we believe the Huntington Bank branch acquisition, which is scheduled to close in June, will help us manage our funding costs this year."

(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) 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.

(e) 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 includes the provision for unfunded commitments), excluding 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, which adjusts net interest income for the tax-favored status of certain loans and investment securities and acquisition related costs, to be a meaningful measure as it enhances the comparability of net interest income arising from taxable and tax-exempt sources and excludes acquisition related costs.

(f) 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.

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