A Decrease in 1031 Exchange Activity and Seasonal Outflows in the Mortgage Servicing Industry, Which are Also High-Cost, Contributed to Traditional Deposit Outflows

Signature Bank (NASDAQ:SBNY), a New York-based full-service commercial bank, today announced results for its fourth quarter ended December 31, 2022.

Net income for the 2022 fourth quarter was $300.8 million, or $4.65 diluted earnings per share, versus $272.0 million, or $4.34 diluted earnings per share, for the 2021 fourth quarter. The increase in net income for the 2022 fourth quarter, versus the comparable quarter last year, is primarily the result of an increase in net interest income, fueled by strong loan and securities growth, as well as higher interest rates. Pre-tax, pre-provision earnings were $450.6 million for the 2022 fourth quarter, representing an increase of $65.2 million, or 16.9 percent, compared with $385.4 million for the 2021 fourth quarter.

Net interest income for the 2022 fourth quarter reached $638.7 million up $102.8 million, or 19.2 percent, when compared with the fourth quarter of 2021. This increase is primarily due to strong loan and securities growth along with higher prevailing market interest rates. Total assets were $110.36 billion at December 31, 2022, decreasing $8.08 billion, or 6.8 percent, from $118.45 billion at December 31, 2021. Average assets for the 2022 fourth quarter remained relatively flat at $112.71 billion versus the comparable period a year ago.

Deposits for the 2022 fourth quarter decreased $14.19 billion, to $88.59 billion, or 13.8 percent, including a non-interest bearing deposit reduction of $5.86 billion, which brings our non-interest bearing mix to 35.6 percent of total deposits at December 31, 2022. Deposits over the last twelve months declined 16.5 percent, or $17.54 billion, when compared with deposits at the end of 2021. The decline was driven by a challenging cryptocurrency environment and our planned reduction in Digital Asset Banking deposits, which were down $12.39 billion, along with our decision not to match the December Fed Funds rate increase. Average total deposits for 2022 were $103.43 billion, growing $18.12 billion, or 21.2 percent, versus average total deposits of $85.31 billion for 2021.

"At the onset of 2022, we set several goals, including the hiring of numerous private client banking teams and hundreds of colleagues to support our geographic expansion; increasing annual earnings to a record level; and, growing both our loan and deposit portfolios substantially. Most of these were met. During the 2022 second quarter, our newest national business line, the Healthcare Banking and Finance team, was launched. Throughout the year, 12 private client banking teams were onboarded, 3 of which in Nevada, marking the Bank's entry into the state. To support this team growth, we added hundreds of colleagues across various operational and support areas. Although we grew loans by a strong $9.43 billion, 2022 presented deposit challenges. While we expected to see continued deposit growth, albeit not at 2020 or 2021 levels, seven Fed rate hikes during 2022 totaling 425 basis points, coupled with quantitative tightening and the proliferation of off balance sheet alternatives, resulted in the most difficult deposit environment we have seen in our 22-year history. The arduous rate environment, along with challenges in the digital asset space, led to deposit declines, which we overcame with little difficulty, given our robust liquidity position. Despite these deposit headwinds, we still earned record net income of $1.34 billion and a record return on common equity of 16.35 percent for the year," said Joseph J. DePaolo, Signature Bank President and Chief Executive Officer.

"Looking ahead, we have plans to further grow our established franchise in 2023 by continuing our effort to hire new banking teams and expanding geographically while remaining mindful of the volatile economic environment. We see growth on the horizon because when Signature Bank lifts out banking teams, it is with top performers who should thrive through our private client banking approach. We look forward to future successes as we stay with our founding and distinguishing single-point-of-contact, team-based banking model, which is the hallmark of our institution," DePaolo concluded.

Scott A. Shay, Chairman of the Board, added: "Over the years, we have continued to reiterate that Signature Bank was built to be well positioned to navigate tough times, and we continue to prove this to be the case. Throughout our 22 years in operation, this institution has faced many economic challenges, including NYC job losses in 2001-2002 as a result of the 9-11 tragedy, which happened only four short months after our founding. This was followed by the Great Financial Crisis of 2008-2010, the COVID-19 shutdown and the list goes on. On the heels of every challenge, Signature Bank emerged stronger, which will be the case this time as well.

With more than half a trillion dollars of deposits leaving the banking system in the second and third quarters of 2022 alone, the market for deposits has turned quite competitive. In that context, Signature Bank consciously decided to exit deposit relationships in certain traditional banking sectors that sought the highest marginal pricing from banks willing to pay maximum interest rates. We believe our service is invaluable, and the overwhelming majority of our clients appreciate that.

We remain very optimistic about the future prospects of Signature Bank. Our increasing the quarterly dividend is a sheer reflection of that confidence as well as our ability to continue to deliver consistent earnings to our shareholders."

Net Interest Income

Net interest income for the 2022 fourth quarter was $638.7 million, an increase of $102.8 million, or 19.2 percent, when compared with the same period last year, primarily due to loans and securities growth along with higher prevailing market interest rates. Average interest-earning assets of $110.13 billion for the 2022 fourth quarter represent a decrease of $1.50 billion, or 1.3 percent, from the 2021 fourth quarter. Due to higher interest rates across all of our asset classes, the yield on interest-earning assets for the 2022 fourth quarter increased 202 basis points to 4.18 percent, compared to the fourth quarter of last year.

Average cost of deposits and average cost of funds for the fourth quarter of 2022 each increased by 172 basis points, to 1.91 percent and 1.99 percent, respectively, versus the comparable period a year ago.

Net interest margin on a tax-equivalent basis for the 2022 fourth quarter was 2.31 percent versus 2.38 percent in the 2022 third quarter, and 1.91 percent reported in the 2021 fourth quarter.

Provision for Credit Losses

The Bank's provision for credit losses for the fourth quarter of 2022 was $42.8 million, an increase of $35.9 million, or over 100 percent, versus the 2021 fourth quarter. The increase in the provision for credit losses for the fourth quarter, compared to the same quarter last year, was predominantly attributable to a deteriorating macroeconomic forecast, particularly related to interest rate, GDP and unemployment forecasts, compared with the same period last year.

Net charge-offs for the 2022 fourth quarter were $18.2 million, or 0.10 percent of average loans, on an annualized basis, versus $10.2 million, or 0.06 percent, for the 2022 third quarter and net charge-offs of $33.7 million, or 0.22 percent, for the 2021 fourth quarter.

Non-Interest Income and Non-Interest Expense

Non-interest income for the 2022 fourth quarter was $45.2 million, up $11.8 million when compared with $33.5 million reported in the 2021 fourth quarter. The increase was primarily due to a $9.2 million increase in fees and service charges and a $4.2 million increase in other income, primarily foreign currency activity. This was partially offset by a decrease of $2.2 million in net gains on sales of loans.

Non-interest expense for the fourth quarter of 2022 was $233.3 million, an increase of $49.4 million, or 26.8 percent, versus $183.9 million reported in the 2021 fourth quarter. The increase was predominantly due to the addition of new private client banking teams, national banking practices, and operational personnel, as well as client activity related expenses that have increased with the growth in our clients and businesses.

The Bank's efficiency ratio was 34.11 percent for the 2022 fourth quarter compared with 32.31 percent for the same period a year ago, and 31.41 percent for the third quarter of 2022.

Loans

Loans, excluding loans held for sale, increased $452.3 million to $74.29 billion in the 2022 fourth quarter, versus $73.84 billion at September 30, 2022. Average loans, excluding loans held for sale, reached $74.46 billion in the 2022 fourth quarter, growing $0.99 billion, or 1.3 percent, from the 2022 third quarter and $13.96 billion, or 23.1 percent, from the fourth quarter of 2021.

At December 31, 2022, non-accrual loans were $184.0 million, representing 0.25 percent of total loans and 0.17 percent of total assets, compared with non-accrual loans of $185.3 million, or 0.25 percent of total loans, at September 30, 2022 and $218.3 million, or 0.34 percent of total loans, at December 31, 2021. At December 31, 2022, the ratio of allowance for credit losses for loans and leases to total loans, was 0.66 percent, versus 0.63 percent at September 30, 2022 and 0.73 percent at December 31, 2021. Additionally, the ratio of allowance for credit losses for loans and leases to non-accrual loans, or the coverage ratio, was 266 percent for the 2022 fourth quarter versus 251 percent for the third quarter of 2022 and 217 percent for the 2021 fourth quarter.

Capital

The Bank's Tier 1 leverage, common equity Tier 1 risk-based, Tier 1 risk-based, and total risk-based capital ratios were approximately 8.79 percent, 10.42 percent, 11.21 percent, and 12.33 percent, respectively, as of December 31, 2022. Each of these ratios is well in excess of regulatory requirements. The Bank's strong risk-based capital ratios reflect the relatively low risk profile of the Bank's balance sheet. The Bank's tangible common equity ratio remains strong at 6.62 percent.

The Bank declared a cash dividend of $0.70 per share, a $0.14 per share increase, payable on or after February 10, 2023 to common stockholders of record at the close of business on January 27, 2023. The Bank also declared a cash dividend of $12.50 per share payable on or after March 30, 2023 to preferred shareholders of record at the close of business on March 17, 2023. In the fourth quarter of 2022, the Bank paid a cash dividend of $0.56 per share to common stockholders of record at the close of business on October 29, 2022. The Bank also paid a cash dividend of $12.50 per share to preferred shareholders of record at the close of business on December 17, 2021.

(4)		We define tangible common equity as the ratio of total tangible common equity to total tangible assets (the "TCE ratio"). Tangible common equity is considered to be a non-GAAP financial measure and should be considered in addition to, not as a substitute for or superior to, financial measures determined in accordance with GAAP. The TCE ratio is a metric used by management to evaluate the adequacy of our capital levels. In addition to tangible common equity, management uses other metrics, such as Tier 1 capital related ratios, to evaluate capital levels.

NON-GAAP FINANCIAL MEASURES

(unaudited)

This press release contains both financial measures based on GAAP and non-GAAP financial measures where management believes that the presentation of certain non-GAAP financial measures assists investors when comparing results period-to-period in a more consistent manner and provides a better measure of Signature Bank's results. These non-GAAP measures include the Bank's (i) tangible common equity ratio, (ii) efficiency ratio, (iii) yield on interest-earning assets, tax-equivalent basis, (iv) net interest margin, tax-equivalent basis, and (v) pre-tax, pre-provision earnings. These non-GAAP measures should not be considered a substitute for GAAP-basis measures and results. We strongly encourage investors to review our consolidated financial statements in their entirety and not to rely on any single financial measure. Because non-GAAP financial measures are not standardized, it may not be possible to compare these financial measures with other companies' non-GAAP financial measures having the same or similar names.
