1ST SOURCE CORP (SRCE) FY 2021 MD&A

LIQUIDITY AND CAPITAL RESOURCES

Core Deposits — Our major source of investable funds is provided by stable core deposits consisting of all interest bearing and noninterest bearing deposits, excluding brokered certificates of deposit, listing services certificates of deposit and certain certificates of deposit over $250,000 based on established FDIC insured deposits. In 2021, average core deposits equaled 78.04% of average total assets, compared to 73.64% in 2020 and 71.48% in 2019. The effective rate of core deposits in 2021 was 0.12%, compared to 0.39% in 2020 and 0.77% in 2019.

Average noninterest bearing core deposits increased 22.96% in 2021 compared to an increase of 30.65% in 2020. These represented 31.20% of total core deposits in 2021, compared to 29.20% in 2020, and 25.11% in 2019.

Purchased Funds — We use purchased funds to supplement core deposits, which include certain certificates of deposit over $250,000, brokered certificates of deposit, listing services certificates of deposit, over-night borrowings, securities sold under agreements to repurchase, commercial paper, and other short-term borrowings. Purchased funds are raised from customers seeking short-term investments and are used to manage the Bank’s interest rate sensitivity. During 2021, our reliance on purchased funds decreased to 6.41% of average total assets from 9.76% in 2020.

Shareholders’ Equity — Average shareholders’ equity equated to 11.73% of average total assets in 2021, compared to 12.15% in 2020. Shareholders’ equity was 11.32% of total assets at year-end 2021, compared to 12.12% at year-end 2020. We include unrealized gains (losses) on available-for-sale securities, net of income taxes, in accumulated other comprehensive income (loss) which is a component of shareholders’ equity. While regulatory capital adequacy ratios exclude unrealized gains (losses), it does impact our equity as reported in the audited financial statements. The unrealized (losses) gains on available-for-sale securities, net of income taxes, were $(9.86) million and $18.37 million at December 31, 2021 and 2020, respectively.

Other Liquidity — Under Indiana law governing the collateralization of public fund deposits, the Indiana Board of Depositories determines which financial institutions are required to pledge collateral based on the strength of their financial ratings. We have been informed that no collateral is required for our public fund deposits. However, the Board of Depositories could alter this requirement in the future and adversely impact our liquidity. Our potential liquidity exposure if we must pledge collateral is approximately $923 million.

Liquidity Risk Management — The Bank’s liquidity is monitored and closely managed by the Asset/Liability Management Committee (ALCO), whose members are comprised of the Bank’s senior management. Asset and liability management includes the management of interest rate sensitivity and the maintenance of an adequate liquidity position. The purpose of interest rate sensitivity management is to stabilize net interest income during periods of changing interest rates.

Liquidity management is the process by which the Bank ensures that adequate liquid funds are available to meet short-term and long-term financial commitments on a timely basis. Financial institutions must maintain liquidity to meet day-to-day requirements of depositors and borrowers, take advantage of market opportunities and provide a cushion against unforeseen needs.

Liquidity of the Bank is derived primarily from core deposits, principal payments received on loans, the sale and maturity of investment securities, net cash provided by operating activities, and access to other funding sources. The most stable source of liability-funded liquidity is deposit growth and retention of the core deposit base. The principal source of asset-funded liquidity is available-for-sale investment securities, cash and due from banks, overnight investments, securities purchased under agreements to resell, and loans and interest bearing deposits with other banks maturing within one year. Additionally, liquidity is provided by repurchase agreements, and the ability to borrow from the Federal Reserve Bank (FRB) and the Federal Home Loan Bank (FHLB).

The Bank’s liquidity strategy is guided by internal policies and the Interagency Policy Statement on Funding and Liquidity Risk Management. Internal guidelines consist of:

(i)Available Liquidity (sum of short term borrowing capacity) greater than $500 million;

(ii)Liquidity Ratio (total of net cash, short term investments and unpledged marketable assets divided by the sum of net deposits and short term liabilities) greater than 15%;

(iii)Dependency Ratio (net potentially volatile liabilities minus short term investments divided by total earning assets minus short term investments) less than 15%; and

(iv)Loans to Deposits Ratio less than 100%

At December 31, 2021, we were in compliance with the foregoing internal policies and regulatory guidelines.

The Bank also maintains a contingency funding plan that assesses the liquidity needs under various scenarios of market conditions, asset growth and credit rating downgrades. The plan includes liquidity stress testing which measures various sources and uses of funds under the different scenarios. The contingency plan provides for ongoing monitoring of unused borrowing capacity and available sources of contingent liquidity to prepare for unexpected liquidity needs and to cover unanticipated events that could affect liquidity.

We have borrowing sources available to supplement deposits and meet our funding needs. 1st Source Bank has established relationships with several banks to provide short term borrowings in the form of federal funds purchased. At December 31, 2021, we had no borrowings in the federal funds market. We could borrow $245.00 million in additional funds for a short time from these banks on a collective basis. As of December 31, 2021, we had $44.15 million outstanding in FHLB advances and could borrow an additional $510.31 million contingent on the FHLB activity-based stock ownership requirement. We also had no outstandings with the FRB and could borrow $453.93 million as of December 31, 2021.

Interest Rate Risk Management — ALCO monitors and manages the relationship of earning assets to interest bearing liabilities and the responsiveness of asset yields, interest expense, and interest margins to changes in market interest rates. In the normal course of business, we face ongoing interest rate risks and uncertainties. We may utilize interest rate swaps to partially manage the primary market exposures associated with the interest rate risk related to underlying assets, liabilities, and anticipated transactions.

A hypothetical change in net interest income was modeled by calculating an immediate 200 basis point (2.00%) and 100 basis point (1.00%) increase and a 100 basis point (1.00%) decrease in interest rates across all maturities. The following table shows the aggregate hypothetical impact to pre-tax net interest income.

The earnings simulation model excludes the earnings dynamics related to how fee income and noninterest expense may be affected by changes in interest rates. Actual results may differ materially from those projected. The use of this methodology to quantify the market risk of the balance sheet should not be construed as an endorsement of its accuracy or the accuracy of the related assumptions.

At December 31, 2021 and 2020, the impact of these hypothetical fluctuations in interest rates on our derivative holdings was not significant, and, as such, separate disclosure is not presented. We manage the interest rate risk related to mortgage loan commitments by entering into contracts for future delivery of loans with outside parties. See Part II, Item 8, Financial Statements and Supplementary Data — Note 18 of the Notes to Consolidated Financial Statements.

Commitments and Contractual Obligations — In the ordinary course of operations, we enter into certain contractual obligations. Such obligations include customer deposits, the funding of operations through debt issuances as well as operating leases for the rent of premises and equipment. Additionally, we routinely enter into contracts for services that may require payment to be provided in the future and may contain penalty clauses for early termination of the contract. Further discussion of commitments and contractual obligations is included in Part II, Item 8, Financial Statements and Supplementary Data — Notes 10, 11, 12 and 18 of the Notes to Consolidated Financial Statements.

We also enter into derivative contracts under which we are required to either receive cash from, or pay cash to, counterparties depending on changes in interest rates. Derivative contracts are carried at fair value on the consolidated balance sheet with the fair value representing the net present value of expected future cash receipts or payments based on market interest rates as of the balance sheet date. The fair value of the contracts changes daily as market interest rates change. Further discussion of derivative contracts is included in Part II, Item 8, Financial Statements and Supplementary Data — Note 19 of the Notes to Consolidated Financial Statements.

OFF-BALANCE SHEET ARRANGEMENTS

Assets under management and assets under custody are held in fiduciary or custodial capacity for our clients. In accordance with U.S. generally accepted accounting principles, these assets are not included on our balance sheet.

We are also party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of our clients. These financial instruments include commitments to extend credit and standby letters of credit. Further discussion of these commitments is included in Part II, Item 8, Financial Statements and Supplementary Data — Note 18 of the Notes to Consolidated Financial Statements.
