GRAND RAPIDS, Mich., April 27, 2023 - Independent Bank Corporation (NASDAQ: IBCP) reported first quarter 2023 net income of $13.0 million, or $0.61 per diluted share, versus net income of $18.0 million, or $0.84 per diluted share, in the prior-year period.

William B. (“Brad”) Kessel, the President and Chief Executive Officer of Independent Bank Corporation, commented: “Our deposit base has remained stable throughout the recent troubles experienced in the banking industry, and we have been able to remain focused on serving the needs of our customers and bringing in new relationships to the bank. As a result, I am pleased to report another quarter of strong financial results. We grew total loans by $44.5 million (5.2% annualized) while maintaining a low level of past dues. Importantly, we generated core deposit growth of $93.1 million (9.1% annualized) in the first quarter of 2023. Additionally, I am pleased with our team’s continued focus on efficiency and expense management. Independent Bank’s operating strategy remains unchanged as we continue to add talented bankers to the commercial banking team to assist in our goal of achieving a greater market share across our footprint. We have a granular deposit base, with approximately 22.6% of deposits uninsured and a high level of available liquidity with $2.4 billion in secured borrowing access and borrowing capacity on unpledged securities.”

Significant items impacting comparable first quarter 2023 and 2022 results include the following:

•Changes in the fair value due to price of capitalized mortgage loan servicing rights (the “MSR Changes”) of  $(0.6) million ($(0.02) per diluted share, after taxes) for the three-month period ended March 31, 2023, as compared to $8.5 million ($0.31 per diluted share, after taxes) for the three-months ended March 31, 2022.

•The provision for credit losses on loans was a credit of $0.8 million ($0.03 per diluted share, after taxes) in the first quarter ended March 31, 2023, as compared to a credit of $1.6 million ($0.06 per diluted share, after taxes) in the first quarter ended March 31, 2022.

•The provision for credit losses on securities held to maturity (“HTM”) was an expense of $3.0 million ($0.11 per diluted share, after taxes) in the first quarter ended March 31, 2023, as compared to a provision of zero in the first quarter ended March 31, 2022.

Operating Results

The Company’s net interest income totaled $38.4 million during the first quarter of 2023, an increase of $5.4 million, or 16.5% from the year-ago period, and down $2.2 million, or 5.3%, from the fourth quarter of 2022. The Company’s tax equivalent net interest income as a percent of average interest-earning assets (the “net interest margin”) was 3.33% during the first quarter of 2023, compared to 3.00% in the year-ago period, and 3.52% in the fourth quarter of 2022. The year-over-year quarterly increase in net interest income was due to an increase in average interest-earning assets as well as an increase in the net interest margin. The decrease in net interest income compared to the linked quarter was due to a decrease in net interest margin that was partially offset by an increase in average interest-earning assets. Average interest-earning assets were $4.70 billion in the first quarter of 2023, compared to $4.49 billion in the year ago quarter and $4.64 billion in the fourth quarter of 2022.

Non-interest income totaled $10.6 million for the first quarter of 2023, compared to $18.9 million in the comparable prior year period. These changes were primarily due to variances in mortgage banking related revenues and a loss on securities available for sale.

Net gains on mortgage loans in the first quarters of 2023 and 2022, were approximately $1.3 million and $0.8 million, respectively. The increase in net gains on mortgage loans was primarily due to a increase in the gain on sale margin on mortgage loan sold that was partially offset by a decrease in the volume of mortgage loans sold.

Mortgage loan servicing, net, generated income of $0.7 million and $9.6 million in the first quarters of 2023 and 2022, respectively. The significant variance in mortgage loan servicing, net is primarily due to changes in the fair value of capitalized mortgage loan servicing rights associated with changes in mortgage loan interest rates and expected future prepayment levels. Mortgage loan servicing, net activity is summarized in the following table:

	Three months ended
	3/31/2023		3/31/2022
	(In thousands)
Mortgage loan servicing, net:
Revenue, net	$	2,222	$	2,083
Fair value change due to price	(635)		8,452
Fair value change due to pay-downs	(861)		(894)
Total	$	726	$	9,641

Non-interest expenses totaled $31.0 million in the first quarter of 2023, compared to $31.5 million in the year-ago period. This decrease is due in part to declines in compensation and employee benefits and occupancy, net, that were partially offset by increases in data processing and FDIC insurance expense. The decrease in compensation and employee benefits is primarily related to lower performance based compensation. The decrease in occupancy primarily relates to lower costs due to a reduction in snow removal expenses, a reduction in Covid-19 related expenses as well as generally lower number of properties maintained. The increase in data processing is generally attributed to the prior year including certain one-time credits from our data processing provider and an increase in cost due annual asset growth and CPI increases. The increase in FDIC deposit insurance is primarily attributed to a new two basis point increase in deposit insurance rate effective for us on January 1, 2023.

The Company recorded income tax expense of $2.9 million in the first quarter of 2023. This compares to an income tax expense of $4.1 million in the first quarter of 2022. The changes in income tax expense principally reflect changes in pre-tax earnings in 2023 relative to 2022.

Asset Quality

A breakdown of non-performing loans by loan type is as follows:

	3/31/2023			12/31/2022			3/31/2022
Loan Type	(Dollars in thousands)
Commercial	$	36		$	38		$	59
Mortgage	5,536			4,745			5,166
Installment	644			598			668
Sub total	6,216			5,381			5,893
Less - government guaranteed loans	2,330			1,660			859
Total non-performing loans	$	3,886		$	3,721		$	5,034
Ratio of non-performing loans to total portfolio loans	0.11		%	0.11		%	0.17		%
Ratio of non-performing assets to total assets	0.09		%	0.08		%	0.11		%
Ratio of allowance for credit losses to total non-performing loans	1300.82		%	1409.16		%	906.38		%

The provision for credit losses on loans was a credit of $0.8 million and $1.6 million in the first quarters of 2023 and 2022, respectively. The quarterly change in the provision for credit losses in 2023 compared to 2022, was primarily the result of a a decrease in the pooled loan reserve that was partially offset by a net change in subjective loan allocations. We recorded loan net charge offs of $1.1 million and $0.1 million in the first quarters of 2023 and 2022, respectively. At March 31, 2023, the allowance for credit losses for loans totaled $50.6 million, or 1.44% of total portfolio loans compared to $52.4 million, or 1.51% of total portfolio loans at December 31, 2022. The quarterly increase in the provision for credit losses for securities HTM in 2023 compared to 2022, was the result of a loss incurred on a $3.0 million subordinated debt security that defaulted during the quarter.

Balance Sheet, Capital and Liquidity

Total assets were $5.14 billion at March 31, 2023, an increase of $139.1 million from December 31, 2022. Loans, excluding loans held for sale, were $3.51 billion at March 31, 2023, compared to $3.47 billion at December 31, 2022.  Deposits totaled $4.54 billion at March 31, 2023, an increase of $165.7 million from December 31, 2022. This increase is primarily due to growth in savings and interest-bearing checking, reciprocal, time and brokered time deposit account balances that were partially offset by a decrease in non-interest bearing deposit account balances.

Cash and cash equivalents totaled $227.0 million at March 31, 2023, versus $74.4 million at December 31, 2022. Securities available for sale (“AFS”) totaled $767.5 million at March 31, 2023, versus $779.3 million at December 31, 2022.

Total shareholders’ equity was $367.7 million at March 31, 2023, or 7.16% of total assets compared to $347.6 million or 6.95% at December 31, 2022. Tangible common equity totaled $337.0 million at March 31, 2023, or $15.94 per share compared to $316.7 million or $15.04 per share at December 31, 2022. The increase in shareholder equity as well as tangible common equity are primarily the result of a decrease in accumulated other comprehensive loss related to unrealized losses on securities available for sale due to a decrease in interest rates as well as earnings retention.

The Company’s wholly owned subsidiary, Independent Bank, remains significantly above “well capitalized” for regulatory purposes with the following ratios:

Regulatory Capital Ratios	3/31/2023		12/31/2022		Well Capitalized Minimum
Tier 1 capital to average total assets	8.61	%	8.56	%	5.00	%
Tier 1 common equity  to risk-weighted assets	11.15	%	10.97	%	6.50	%
Tier 1 capital to risk-weighted assets	11.15	%	10.97	%	8.00	%
Total capital to risk-weighted assets	12.40	%	12.22	%	10.00	%

At March 31, 2023, in addition to liquidity available from our normal operating, funding, and investing activities, we had unused credit lines with the FHLB and FRB of approximately $930.1 million and $502.7 million, respectively. We also had

3

approximately $928.5 million in fair value of unpledged securities AFS and HTM at March 31, 2023 which could be pledged for an estimated additional borrowing capacity at the FHLB and FRB of approximately $854.9 million.

Share Repurchase Plan

On December 20, 2022, the Board of Directors of the Company authorized the 2023 share repurchase plan. Under the terms of the 2023 share repurchase plan, the Company is authorized to purchase up to 1,100,000 shares, or approximately 5% of its then outstanding common stock.
