Step 01 — Business Overview

PacWest Bancorp (NASDAQ: PACW)

Acquired by Banc of California (BANC) | November 30, 2023

1. Company Summary

PacWest Bancorp was a California-based bank holding company headquartered in Beverly Hills, California. Through its primary subsidiary, Pacific Western Bank (PWB), PacWest operated as a full-service commercial bank serving small-to-medium-sized businesses and entrepreneurs across California and select national markets. At its peak in Q1 2023, PacWest held approximately $44.3 billion in assets and operated roughly 70 branch locations, predominantly in California.

PacWest was built through a long series of acquisitions over the prior two decades, assembling a franchise that combined traditional California community banking with a specialized venture banking division serving technology startups and their investors. This venture banking focus — modeled loosely on Silicon Valley Bank's franchise — proved to be both a growth driver during the zero-rate era and a critical structural vulnerability during the 2023 banking crisis.

In May 2023, following the collapse of Silicon Valley Bank (SVB), Signature Bank, and First Republic, PACW experienced a severe deposit run, losing approximately $5.7 billion in deposits in just two weeks (early May 2023). The company's stock fell approximately 50% in a single session on May 4, 2023. After a strategic review process, PACW agreed to merge with Banc of California in a merger-of-equals transaction announced July 25, 2023, which closed November 30, 2023.

2. Business Segments

PacWest reported as a single banking segment but had meaningful internal divisions:

a) Community Banking

• Traditional commercial real estate lending and C&I (commercial & industrial) loans
• Serving small-to-mid-sized businesses in California
• Core deposit gathering through branch network
• Roughly 70 branches concentrated in Southern California and Bay Area

b) Venture Banking (Pacific Western Bank — National Division)

• Technology and life science startup lending (venture debt)
• Deposit relationships with VC-backed companies and their investors
• Warehouse lending and asset-based lending
• National footprint beyond California branches
• Modeled similarly to SVB but smaller scale
• This segment carried disproportionately high uninsured deposit balances

c) Asset Management / Specialty Finance

• Small portfolio of specialty finance assets
• Loan participations and other banking activities

4. Product and Service Mix

5. Strategic History (Acquisition-Driven Growth)

PacWest was assembled through more than 30 acquisitions over 20 years:

The acquisition-driven model created a complex, multi-culture bank with significant goodwill and intangible assets on the balance sheet — a factor that complicated capital ratio analysis during the crisis.

6. Leadership at Merger (Final Standalone Period)

Paul Taylor was a relatively new CEO who inherited a bank already under deposit pressure from rising rates. His management of the crisis — including proactive liquidity building, asset sales, and eventual merger negotiation — is assessed in Step 08.

7. Merger Terms (BANC Merger)

• Announced: July 25, 2023
• Structure: Merger of equals; Pacific Western Bank merged into Banc of California
• Exchange ratio: Each PACW share received 0.6569 shares of BANC
• Implied value at announcement: Approximately $9.60 per PACW share (at BANC stock price)
• Combined entity: ~$9.4B in combined deposits; ~$36B assets (post-deleveraging)
• Merger closed: November 30, 2023
• Warburg Pincus & Centerbridge: Provided $400M equity capital to combined BANC entity at merger close
• PACW delisted: NASDAQ delisting effective November 30, 2023

8. One-Line Characterization

PacWest Bancorp was a California commercial bank that grew rapidly through acquisitions and a venture banking niche, but whose heavy reliance on uninsured deposits created an existential vulnerability that collapsed into a forced merger during the 2023 regional banking crisis.

Step 04 — Financial Snapshot

PacWest Bancorp (NASDAQ: PACW)

FY2020–Q3 2023 | Note: FY2023 incomplete due to merger close November 30, 2023

1. Income Statement Summary

All figures in millions USD except per-share data.

Q2 2023 net loss note: The $(1,250)M net loss in Q2 2023 was driven by a ~$1.3B non-cash goodwill impairment charge triggered by the collapse in market capitalization during the deposit crisis. Core pre-goodwill operating income was modestly positive.

2. Balance Sheet Summary

Balance sheet narrative: Total assets peaked at $44.3B in Q1 2023 then contracted sharply as deposits fled and the bank sold assets to raise liquidity. Borrowings surged from $2.5B at YE2022 to $5.8B at Q3 2023 — reflecting FHLB advances and BTFP utilization to replace fled deposits. The equity book contracted due to the Q2 2023 goodwill impairment.

3. Capital Ratios

Capital narrative: PACW remained technically well-capitalized throughout the crisis. The decline in CET1 to 8.9% at YE2022 reflected goodwill accumulation from acquisitions. CET1 recovered to 10.4% by Q3 2023 as the balance sheet shrank (risk-weighted assets fell). Capital ratios were NOT the primary problem — deposit confidence was.

4. Key Bank Profitability Metrics

Profitability narrative: On paper, PACW was a well-run, efficient bank through FY2022. ROTCE of 28.2% in FY2022 was exceptional for a regional bank. The rapid deterioration in ROA and ROE in 2023 reflects the dual hit of NIM compression (rising deposit costs, expensive borrowings) and balance sheet shrinkage (fewer assets earning income).

5. Deposit Composition — Crisis Timeline

Note: The Q2 2023 figure shows some stabilization but masks significant intra-quarter volatility. Q3 2023 includes brokered deposits and time deposits added to staunch outflows.

6. Per-Share Value Progression

The stock traded at significant discounts to TBV throughout the crisis, reflecting the market's correct assessment that deposit franchise value had been impaired far beyond what accounting goodwill write-downs captured.

2. Lessons as Catalysts — What This Case Teaches Investors

PACW's crisis and merger produced several durable lessons that served as "catalysts" for regulatory and industry change:

For investors interested in PACW's assets through the BANC lens:

4. Bull Case (Standalone PACW — Hypothetical Stabilization Scenario)

Frame: What would have needed to go right for PACW to survive as an independent entity?

Bull Case — 3 Key Pillars:

1. Deposit stabilization via Fed rate cuts and VC recovery: If the Fed had pivoted to rate cuts in mid-2023 (rather than continuing to hike to 5.25–5.50%), deposit cost pressure would have eased and money market fund attractiveness would have diminished. Simultaneously, a VC funding recovery would have replenished venture client deposits organically. Deposit runoff would have slowed and eventually reversed. PACW's liquidity buffer would have been sufficient to bridge to this scenario.

2. Asset yield repricing outrunning liability cost increases: PACW's floating-rate loan book was repricing upward with each Fed hike. If deposit repricing had stabilized (beta plateauing) while asset yields continued rising into 2024, NIM would have expanded again to the 3.5–4.0% range, restoring earnings power and supporting organic capital generation. This would have enabled dividend restoration and a re-rating of the stock to 1.0–1.2x TBV.

3. Strategic investor or capital raise: If PACW had successfully raised $500M–$1B in equity capital in Q2 2023 (at a steep dilution but stabilizing price), the market's confidence concern would have been addressed directly. The capital would have thickened TCE/TA to 5%+, improved uninsured deposit coverage to >130%, and removed the existential questions about solvency. Post-capital raise, deposit stabilization was plausible.

Bull Case Implied Return (Hypothetical): From the $3.17 trough on May 4, 2023 to $20–25 TBV recovery by 2025 = 6–8x stock appreciation over 2 years.

5. Bear Case (What Actually Happened + Worse Scenarios)

Bear Case — 3 Key Pillars:

1. Uninsured deposit concentration was irreparably impaired: The venture banking deposit franchise — PACW's growth engine and NIM driver — was structurally dependent on conditions (cheap deposits from VC-funded startups) that vanished simultaneously with the crisis. Even without a full bank run, the organic decline in venture deposits as companies burned cash in a frozen VC market meant PACW's deposit base was going to shrink for 12–24+ months regardless. The crisis simply accelerated what would have been a slow erosion. There was no realistic path to rebuilding 73% uninsured deposits to a stable position without a fundamental change in business model.

2. Earnings power permanently impaired without deposit rebuild: PACW's 2022 ROTCE of 28% was built on (a) cheap deposits (NID at near-zero cost), (b) asset repricing windfall, and (c) thin tangible equity. All three tailwinds were reversing simultaneously. Normalized ROTCE for a standalone PACW in 2024–2025 — assuming survival — was realistically 10–14%, barely above cost of equity for a bank with these risk characteristics. The business model was structurally less profitable post-crisis, not temporarily impaired.

3. Capital raise was impossible at non-dilutive terms; merger was the best available outcome: Attempts to raise standalone equity capital in May–June 2023 would have required issuing stock at $5–8/share — a 60–70% discount to TBV — crushing existing shareholders. At that dilution, the pro-forma economics of the capital raise barely justified the cost. The BANC merger at 0.6569x (implying ~$9.60) was materially better than the standalone equity capital alternatives. The bear case for shareholders who held through the crisis materialized; the merger outcome was better than the worst alternative (FDIC receivership), but far worse than 2022 starting prices.
