PACWEST BANCORP ANNOUNCES RESULTS FOR THE THIRD QUARTER 2023

FOR IMMEDIATE RELEASE

THIRD Quarter 2023 Highlights

●

Net loss available to common stockholders of $33.3 million, or a loss of $0.28 per diluted share

●

Pending merger with Banc of California, Inc. is on track with all regulatory approvals received and is expected to close on or about November 30, 2023

●

The Bank put in place a large liquidity base to cautiously navigate the end of the first quarter of 2023 through the third quarter of 2023. The excess borrowings, including $1.4 billion of brokered deposits (at a rate of 5.19%) and the $1.3 billion repurchase agreement facility (at a rate of 8.50%), are expected to roll off in the fourth quarter of 2023. We believe this will accelerate the Bank’s return to more normalized funding levels and improved profitability, with significantly lower interest and FDIC insurance expenses

●

We continue to execute on our profitability initiatives by optimizing resources, contracts, facilities, and processes, the benefits of which we anticipate realizing in the quarters ahead. Third quarter noninterest expense had notable movement, with compensation expense down 14% over the prior quarter to $71.6 million, with a higher than usual FDIC insurance expense that we expect will normalize over time, and with $9.9 million of non-recurring merger-related costs

●

Adjusted loss available to common stockholders of $37.3 million and adjusted diluted loss per common share of $0.31, which exclude the effect of $9.9 million of merger-related costs related to the pending merger with Banc of California, Inc. and a $14.5 million credit related to a legal settlement gain (see GAAP to non-GAAP reconciliation financial tables at the end of this press release)

●

Allowance for loan and lease losses ratio increased from 0.98% to 1.01%

●

Third quarter results were marked by enhanced capital and liquidity

●

All capital ratios increased from June 30, 2023, with CET1 increasing from 11.16% to 11.23%

●

Immediately available liquidity (on-balance sheet liquidity and unused borrowing capacity) of $16.7 billion, with $5.9 billion of available cash on hand at September 30, 2023

●

Community Banking deposits grew by 2% in the quarter as a result of strategic efforts to attract and retain customers

●

Brokered deposits continue to mature, with balances decreasing by $1.9 billion in the quarter. $1.4 billion more are scheduled to mature in the fourth quarter of 2023

●

The repurchase agreement facility interest expense was $35 million in the quarter and the facility will be repaid in December 2023

CEO COMMENTARY

Paul Taylor, President and CEO, commented, “The integration planning for our merger with Banc of California, Inc. continues to progress very well. We expect the closing of the merger to occur on or about November 30, 2023, subject to receipt of stockholder approvals. We all look forward to completing the merger so we can begin to execute on a successful business plan for the combined company that we expect will drive significant value for PacWest’s stockholders, customers, communities, and employees.”

Mr. Taylor concluded, “As we work toward the completion of the merger, our primary strategic focus is adding new deposit customers and continuing to provide outstanding customer service to our existing customers. Our credit quality continues to be stable. Our funding profile improved in the third quarter as we strategically reduced higher-cost brokered deposits and we are pleased to see growth in the Community Bank return. We strategically put in place a high-cost liquidity buffer over the past few quarters to safely navigate the turmoil in the regional banking market. We created this buffer by selling loans and adding customer deposits and wholesale funding. We expect our profitability to improve as we continue to wind down wholesale funding, benefit from lower FDIC insurance expense, and execute on our profitability initiatives.”

INCOME STATEMENT HIGHLIGHTS

NET INTEREST INCOME

Net interest income decreased by $55.3 million to $130.7 million for the third quarter of 2023 compared to $186.1 million for the second quarter of 2023 due mainly to lower interest income on loans and leases and higher interest expense on deposits, offset partially by lower interest expense on borrowings. Interest income on loans and leases decreased by $98.6 million in the third quarter of 2023 due to a $4.8 billion decrease in the average balance of loans and leases and a 54 basis points decrease in the tax equivalent yield on loans and leases compared to the second quarter of 2023. The tax equivalent yield on loans and leases was 5.54% in the third quarter of 2023 compared to 6.08% in the second quarter of 2023. The decrease in the tax equivalent yield on loans and leases was due primarily to lower levels of higher-yielding Civic and construction loans. Interest expense on deposits increased by $27.2 million in the third quarter of 2023 due mainly to increased market rates that contributed to a 36 basis points increase in the cost of total deposits. Interest expense on borrowings decreased by $66.7 million due mainly to a $5.1 billion decrease in the average balance. Interest expense on the repurchase agreement facility is at 8.50% and totaled $35 million in the third quarter. This interest expense will decrease in the fourth quarter, as we intend to pay off this borrowing in mid-December with existing balance sheet liquidity, and be eliminated by the first quarter of 2024.

The tax equivalent NIM was 1.45% for the third quarter of 2023 compared to 1.82% for the second quarter of 2023. The decrease in the NIM was due mainly to the lower yield on loans and leases and a higher cost of total deposits.

The cost of total deposits was 2.98% for the third quarter of 2023 compared to 2.62% for the second quarter of 2023 due mainly to higher market interest rates.

PROVISION FOR CREDIT LOSSES

The following table presents details of the provision for credit losses for the periods indicated:

	Three Months Ended
	September 30,			June 30,			Increase
Provision for Credit Losses	2023			2023			(Decrease)
	(In thousands)
Addition to allowance for loan and lease losses	$	8,000		$	40,000		$	(32,000	)
Reduction in reserve for unfunded loan commitments		(8,000	)		(38,000	)		30,000
Total loan-related provision		-			2,000			(2,000	)
Addition to allowance for held-to-maturity securities		-			-			-
Total provision for credit losses	$	-		$	2,000		$	(2,000	)

There was no provision for credit losses for the third quarter of 2023 compared to $2.0 million for the second quarter of 2023. The provision for the third quarter of 2023 reflected an addition to the allowance for loan and lease losses, primarily due to an increase in qualitative reserves for loans secured by office properties, which was offset by a reduction in the reserve for unfunded commitments due to lower unfunded commitments. The provision for the second quarter of 2023 reflected the impact of an updated economic forecast, higher net charge-offs and higher reserves for downgraded loans largely offset by lower reserves needed for lower loan and unfunded commitment balances.

Noninterest Income

The following table presents details of noninterest income for the periods indicated:

	Three Months Ended
	September 30,			June 30,			Increase
Noninterest Income	2023			2023			(Decrease)
	(In thousands)
Service charges on deposit accounts	$	4,018		$	4,315		$	(297	)
Other commissions and fees		7,641			11,241			(3,600	)
Leased equipment income		14,554			22,387			(7,833	)
Loss on sale of loans and leases		(1,901	)		(158,881	)		156,980
Dividends and gains on equity investments		3,837			2,658			1,179
Warrant loss		(88	)		(124	)		36
LOCOM HFS adjustment		307			(11,943	)		12,250
Other income		15,440			2,265			13,175
Total noninterest income (loss)	$	43,808		$	(128,082	)	$	171,890

Noninterest income increased by $171.9 million to an income of $43.8 million for the third quarter of 2023 compared to a loss of $128.1 million for the second quarter of 2023 due primarily to a $157.0 million decrease in the loss on sale of loans and leases, the $12.3 million increase in the lower of cost or market held for sale (“LOCOM HFS”) adjustment and a $13.2 million increase in other income, partially offset by a $7.8 million decrease in leased equipment income and a $3.6 million decrease in other commissions and fees. The decrease in the loss on sale of loans and leases was due to the $158.9 million of losses recorded in the second quarter of 2023 related to the sale of three significant non-core loan portfolios. The increase in the LOCOM HFS adjustment was due to the negative $11.9 million LOCOM adjustment made in the second quarter of 2023 related to the $478.1 million of loans held for sale at June 30, 2023. The increase in other income is primarily due to a $14.5 million recovery of a prior year legal settlement. The decrease in leased equipment income was due primarily to lower early lease termination gains and rental income compared to the second quarter of 2023. The decrease in other commissions and fees was due primarily to lower loan-related fee income and lower customer success fees.

Total noninterest expense	$	201,103		$	320,437	$	(119,334	)

Noninterest expense decreased by $119.3 million to $201.1 million in the third quarter of 2023 compared to $320.4 million in the second quarter of 2023 due primarily to a decrease of $111.3 million in other expense and a decrease of $11.2 million in compensation expense, offset partially by a $12.7 million increase in insurance and assessments expense. The decrease in other expense was due mainly to $106.8 million of unfunded commitments fair value loss adjustments in the second quarter of 2023. The decrease in compensation expense was due mostly to lower salary expense, stock compensation, and commissions expense. The increase in insurance and assessments was due primarily to higher FDIC assessment expense attributable to an increased assessment rate due to lower core earnings and lower core deposits.

Income Taxes

The effective income tax rate was 12.1% for the third quarter of 2023 compared to 25.3% for the second quarter of 2023. The decrease from the second quarter of 2023 was due primarily to higher disallowed FDIC assessment expense in the third quarter of 2023.

Loans and leases held for investment, net of deferred fees, decreased by $337.3 million, or 1.5% in the third quarter of 2023 to $21.9 billion at September 30, 2023. The overall decrease in the loans and leases balance for the third quarter of 2023 was due primarily to a decrease in commercial loans led by decreases in venture capital loans and asset-based loans.

The allowance for credit losses decreased by $4.9 million in the third quarter of 2023 to $251.9 million at September 30, 2023. This decrease was attributable mainly to lower reserves needed due to the decrease in loans and leases held for investment and unfunded loan commitments.

Net charge-offs over the trailing twelve months were $47.5 million, which resulted in net charge-offs to average loans and leases over the trailing twelve months of 0.19%.

(1) Nonaccrual loans include SBA guaranteed amounts of $13.7 million at September 30, 2023 and $14.8 million at June 30, 2023.

Nonaccrual loans and leases increased by $20.5 million in the third quarter of 2023 to $125.4 million at September 30, 2023, due primarily to an increase in nonaccrual Civic loans. The increase is primarily due to a sale of non-performing Civic loans in the second quarter which made the balance at June 30, 2023, lower than normal.

Statements that are not historical or current facts, including statements about future financial and operational results, expectations, or intentions are forward-looking statements. Such statements often use words such as “anticipates,” “targets,” “expects,” “estimates,” “intends,” “plans,” “believes,” “continue” and other similar expressions or future or conditional verbs such as “will,” “may,” “might,” “should,” “would” and “could.” These forward-looking statements include, but are not limited to, statements regarding the proposed transaction between PacWest and Banc of California, Inc. (“Banc of California”) including statements as to the expected timing, completion and effects of the proposed transaction. Such statements are based on information available at the time of the communication and are based on current beliefs and expectations of PacWest’s and Banc of California’s management and are subject to significant risks, uncertainties and contingencies, many of which are beyond the control of PacWest and Banc of California, which may cause actual results, performance, or achievements to differ materially from those expressed in them. Continued deterioration in general business, economic, and political conditions, geopolitical tensions, uncertainty in U.S. fiscal monetary policy, including the interest rate policies of the Federal Reserve Board, and volatility and disruptions in credit and capital markets could lead to a tightening of credit and an increase in credit losses, adversely affect PacWest’s revenues and the values of our assets and liabilities, increase stock price volatility, and adversely impact our ability to raise capital. In addition, PacWest and its results could be adversely affected by changes in interest rates, continued high inflation, and unemployment rates, our ability to attract and retain deposits and other sources of funding and liquidity particularly in a rising or high interest rate environment, the impact of bank failures or other adverse developments at other banks on general investor sentiment regarding the stability and liquidity of banks, the safety of deposits, and depositor behavior, the quality and composition of our deposits, deterioration in the credit quality of our loan portfolio or in the value of the collateral securing those loans, especially the risks associated with concentrations in real estate related loans, deterioration in the value of our investment securities as a result of rising interest rates or otherwise, our ability to successfully execute on our strategic plan and digital and innovation initiatives, the effectiveness of our risk management framework and quantitative models, legal and regulatory developments, the ability to complete, or any delays in completing, the proposed transaction between us and Banc of California, any failure to realize the anticipated benefits of the transaction when expected or at all, certain restrictions during the pendency of the proposed transaction that may impact our ability to pursue certain business opportunities or strategic transactions, the possibility that the transaction may be more expensive to complete than anticipated, including as a result of unexpected factors or events, diversion of management’s attention from ongoing business operations and opportunities, and potential adverse reactions or changes to business or employee relationships, including those resulting from the completion of the transaction and integration of the companies. We also caution that the amount and timing of any future common stock dividends will depend on the earnings, cash requirements and financial condition of the Company, market conditions, capital requirements, applicable law and regulations (including federal securities laws and federal banking regulations), and other factors deemed relevant by the Company’s Board of Directors, and may be subject to regulatory approval or conditions. Actual results may differ materially from those set forth or implied in the forward-looking statements due to a variety of factors, including the risk factors described in documents filed by PacWest with the U.S. Securities and Exchange Commission (the “SEC”).

All forward-looking statements in this communication are based on information available at the time the statement is made. We are under no obligation (and expressly disclaim any such obligation) to update or alter our forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.

GAAP TO NON-GAAP RECONCILIATIONS

This press release contains certain non-GAAP financial disclosures for: (1) Pre-provision, pre-goodwill impairment, pre-tax net revenue (“PPNR”), (2) PPNR return on average assets (3) return on average tangible common equity, (4) tangible common equity ratio, and (5) tangible book value per common share. The Company uses these non-GAAP financial measures to provide meaningful supplemental information regarding the Company’s operational performance and to enhance investors’ overall understanding of such financial performance. In particular, the use of PPNR, return on average tangible common equity, tangible common equity ratio, and tangible book value per common share is prevalent among banking regulators, investors, and analysts. Accordingly, we disclose the non-GAAP measures in addition to the related GAAP measures (or those calculated from GAAP measures) of: (1) net earnings, (2) return on average assets, (3) return on average equity, (4) equity to assets ratio, (5) book value per common share, and (6) efficiency ratio.

The Company recorded significant non-operating charges in the three months ended September 30, 2023, June 30, 2023, and March 31, 2023, and nine months ended September 30, 2023. Thus, to supplement information regarding the Company’s operational performance and to enhance investors’ overall understanding of such performance, this press release includes non-GAAP financial measures for (1) adjusted return on average tangible common equity, (2) adjusted earnings, (3) adjusted earnings per share, (4) adjusted return on average assets, and (5) adjusted efficiency ratio. These measures help the reader to compare the recent periods with the historical periods more readily. These non-GAAP financial measures should not be considered a substitute for financial measures presented in accordance with GAAP and may be different from the non-GAAP financial measures used by other companies.

The tables below present the reconciliations of these GAAP financial measures to the related non-GAAP financial measures:
