California BanCorp Reports Financial Results for the First Quarter Ended March 31, 2024

Oakland, CA – April 29, 2024 – California BanCorp (NASDAQ: CALB) (the “Company”), whose subsidiary is California Bank of Commerce, announced today its financial results for the first quarter ended March 31, 2024.

The Company reported net income of $3.8 million for the first quarter of 2024, representing a decrease of $1.5 million, or 29%, compared to $5.3 million for the fourth quarter of 2023 and a decrease of $1.6 million, or 30%, compared to $5.4 million in the first quarter of 2023. Excluding the impact of merger related expenses pertaining to the pending transaction with Southern California Bancorp, the Company’s net income for the first quarter of 2024 was $4.8 million (See Interim Consolidated Non-GAAP Data).

Diluted earnings per share were $0.45 for the first quarter of 2024, compared to $0.63 for the fourth quarter of 2023 and $0.64 for the first quarter of 2023. Excluding the impact of merger related expenses, the Company’s diluted earnings per share were $0.57 for the first quarter of 2024 (See Interim Consolidated Non-GAAP Data).

“We delivered another quarter of strong financial performance while maintaining our conservative approach to new loan production and prudent balance sheet management, which resulted in our adjusted return on average assets remaining above 1% when our merger-related expenses are excluded,” said Steven Shelton, Chief Executive Officer of California BanCorp. “We saw positive trends in many key areas including good stability in our net interest margin, disciplined expense management excluding the merger-related expense we recorded in the quarter, and improvement in our asset quality as a result of successfully resolving problem loans with minimal loss incurred. We had a small decline in the size of our balance sheet in the first quarter, as our conservative approach to new loan production resulted in new loan originations being below the level of payoffs we had in the quarter, while we also saw the usual seasonal outflows of demand deposits that occur in the first quarter. These outflows were partially offset by our continued success in adding new commercial relationships that bring noninterest-bearing deposits to the bank.

“We are making good progress on the integration planning for our merger with Southern California Bancorp, which we continue to expect to close during the third quarter of 2024. Prior to the closing, our focus will remain on preparing for a smooth integration so that we can quickly realize all of the synergies projected from our combination, evaluating opportunities to optimize our balance sheet ahead of the merger, and continuing to add attractive commercial relationships that further strengthen our deposit base. As we progress with our integration planning and evaluate the strong market position we will have following the merger, we continue to believe that the combined company will have good opportunities to steadily grow our client roster, increase our market share, generate profitable growth, and consistently enhance the value of our franchise in the years ahead,” said Mr. Shelton.

Net Interest Income and Margin:

Net interest income for the quarter ended March 31, 2024 was $17.7 million, representing a decrease of $859,000, or 5%, from $18.6 million for the three months ended December 31, 2023, and a decrease of $1.0 million, or 6%, from $18.7 million for the quarter ended March 31, 2023. The decrease in net interest income compared to the fourth quarter of 2023 was primarily attributable to a lower balance of average earning assets which was driven by a reduction in loan balances as a result of conservative underwriting combined with decreased demand and pay-offs occurring in the normal course of business. Compared to the first quarter of 2023, the decrease in net interest income resulted from a less favorable mix of earning assets and an increase in the cost of deposits, which negatively impacted net interest margin.

The Company’s net interest margin for the first quarter of 2024 was 3.89%, compared to 3.88% for the fourth quarter of 2023 and 4.02% for the same period in 2023.

Non-Interest Income:

The Company’s non-interest income for the quarters ended March 31, 2024, December 31, 2023, and March 31, 2023 was $1.7 million, $1.3 million, and $1.1 million, respectively. The increase in non-interest income from the fourth quarter of 2023 and the same period in the prior year was primarily due to an increase in service charges and loan related fees.

Net interest income and non-interest income comprised total revenue of $19.4 million, $19.9 million, and $19.9 million for the quarters ended March 31, 2024, December 31, 2023, and March 31, 2023, respectively.

Non-Interest Expense:

The Company’s non-interest expense for the quarters ended March 31, 2024, December 31, 2023, and March 31, 2023 was $13.7 million, $12.2 million, and $11.8 million, respectively. The increase in non-interest expense from the prior periods was primarily due to the recognition of merger related expenses, combined with a decrease in capitalized loan origination costs. Additionally, compared to the same period in the prior year, the Company incurred increases in salaries and benefits as well as premises and equipment. Excluding capitalized loan origination costs and the impact of merger related expenses, non-interest expense for the first quarter of 2024, the fourth quarter of 2023 and the first quarter of 2023 was $13.1 million, $13.0 million, and $12.5 million, respectively (See Interim Consolidated Non-GAAP Data).

The Company’s efficiency ratio, the ratio of non-interest expense to revenues, was 70.57%, 61.36%, and 59.62% for the quarters ended March 31, 2024, December 31, 2023, and March 31, 2023, respectively. Excluding the impact of merger related expenses, the Company’s efficiency ratio was 65.29% for the first quarter of 2024 (See Interim Consolidated Non-GAAP Data).

Balance Sheet:

Total assets of $1.92 billion as of March 31, 2024 represented a decrease of $63.4 million compared to $1.99 billion at December 31, 2023, and a decrease of $128.2 million compared to total assets of $2.05 billion at March 31, 2023. The decrease in total assets from the prior periods was primarily due to conservative new loan production, combined with decreased liquidity related to a reduction in other borrowings.

Total gross loans decreased by $38.6 million, or 2%, to $1.52 billion at March 31, 2024, from $1.56 billion at December 31, 2023 and decreased $96.4 million, or 6%, from $1.62 billion at March 31, 2023. During the first quarter of 2024, commercial loans decreased by $16.2 million, or 3%, real estate related loans decreased by $23.5 million, or 3%, and other loans increased $1.1 million, or 2%. Compared to the same period in the prior year, commercial, real estate other, real estate construction and land, and other loans decreased by $46.1 million, or 7%, $19.3 million, or 2%, $28.0 million, or 44%, and $3.0 million, or 7%, respectively.

Total deposits increased by $14.3 million, or 1%, to $1.64 billion at March 31, 2024 from $1.63 billion at December 31, 2023, and decreased by $78.1 million, or 5%, from $1.72 billion at March 31, 2023. The increase in total deposits during the first quarter of 2024 was primarily due to an increase in money market and savings accounts of $25.2 million, or 4%, and an increase in time deposits of $17.7 million, or 6%, partially offset by a decrease in demand deposits of $28.6 million, or 4%. The decrease in demand deposits was primarily due to the seasonal outflow of deposits that occurs at the beginning of the year for many of our business clients. Compared to the same period last year, the decrease in total deposits was primarily concentrated in noninterest-bearing demand deposits, partially offset by an increase in money market and savings accounts. Noninterest-bearing deposits, primarily commercial business operating accounts, represented 38.6% of total deposits at March 31, 2024, compared to 40.4% at December 31, 2023 and 43.1% at March 31, 2023.

Excluding junior subordinated debt securities, the Company had no outstanding borrowings at March 31, 2024, compared to outstanding borrowings of $75.0 million at December 31, 2023 and March 31, 2023.

Asset Quality:

The provision for credit losses on loans was $301,000 for the first quarter of 2024, compared to $87,000 for the fourth quarter of 2023 and $464,000 for the first quarter of 2023. The Company had net loan charge-offs of $348,000, or 0.02% of gross loans, during the first quarter of 2024, net loan recoveries of $20,000, or 0.00 % of gross loans during the fourth quarter of 2023 and net loan charge-offs of $247,000, or 0.02% of gross loans, during the first quarter of 2023.

Non-performing assets (“NPAs”) to total assets were 0.08% at March 31, 2024, compared to 0.19% at December 31, 2023 and 0.01% at March 31, 2023, with non-performing loans of $1.5 million, $3.8 million and $222,000, respectively, on those dates.

The allowance for credit losses on loans was $16.0 million, or 1.05% of total loans, at March 31, 2024, compared to $16.0 million, or 1.03% of total loans, at December 31, 2023 and $15.4 million, or 0.95% of total loans, at March 31, 2023.

The allowance for credit losses on unfunded loan commitments was $2.0 million, or 0.32% of total unfunded loan commitments, at March 31, 2024, compared to $2.2 million, or 0.32% of total unfunded loan commitments, at December 31, 2023 and $1.7 million, or 0.29% of total unfunded loan commitments, at March 31, 2023.

Capital Adequacy:

At March 31, 2024, shareholders’ equity totaled $200.7 million, compared to $196.5 million at December 31, 2023 and $178.6 million one year ago. Additionally, at March 31, 2024, the Company’s total risk-based capital ratio, tier one capital ratio, and leverage ratio were 13.93%, 10.15%, and 10.17%, respectively; all of which were above the regulatory standards of 10.00%, 8.00%, and 5.00%, respectively, for “well-capitalized” institutions.

“In the past year we achieved 11.9% growth in tangible book value as we accreted capital and strengthened liquidity in response to a very challenging environment for the industry. Our prudent balance sheet management resulted in increases in all of our capital ratios during the first quarter, while we used our strong liquidity to pay off all of our FHLB borrowings early in the quarter,” said Thomas A. Sa, President, Chief Financial Officer and Chief Operating Officer of California BanCorp.
