WESTERN ALLIANCE BANCORPORATION (WAL) stock intrinsic value fair value estimate & owner earnings analysis

Western Alliance Bancorporation is a Phoenix, Arizona-based bank holding company with about $98.7 billion of assets and $81.9 billion of deposits at June 30, 2026. It combines regional commercial banking in Arizona, Nevada and California, now run under the single Western Alliance Bank name, with nationwide specialty businesses. Those include banking for homeowners associations, mortgage warehouse lending, settlement and escrow services, technology and innovation banking, hotel franchise finance, public and nonprofit finance, and lending to other finance companies. It also owns AmeriHome, a large correspondent mortgage business acquired in April 2021 that buys home loans from other lenders and resells them. How we measure what the business earns. Because of AmeriHome, reported operating cash flow swings by billions of dollars a year as its loan inventory moves in and out. We strip out that inventory turnover and other timing items, such as loan fees and bond discounts booked as income before the cash arrives, deferred taxes, and changes in other assets and liabilities. We also subtract stock-based pay and all spending on branches and equipment. Three charges matter most for a bank. First, we charge the provision for loan losses as a cost. Cash-flow statements add it back, but for a lender, loans that go bad are the main cost of doing business. Second, Western Alliance buys low-income-housing tax credit investments every year, writing them down by $64 million to $76 million a year in 2023-2025. The tax savings show up in earnings while the purchase cost does not, so we charge the yearly write-down as a cost. Third, 2023 profit included about $110 million of net one-time losses on loans and bonds sold during that spring's deposit run. We treat these as a consequence of the run, not as part of a normal year, and carry that risk in the bear case instead. On this basis, owner earnings were $9.37 a share in 2022, $7.41 in 2023, $7.03 in 2024 and $8.55 in 2025, up 22% in the latest year. The normal level. We use the 2022-2025 median, about $7.98 a share. These are the four full years of the business as it exists today, with AmeriHome inside it. They include a strong year (2022), the 2023 deposit run and the high-deposit-cost trough that followed (2023-2024), and a recovery (2025). We left out 2021, which has only about nine months of AmeriHome and a one-time release of loan-loss reserves. We tested this level against 2026 so far. The first quarter took two large charge-offs on loans to finance companies: $126.4 million on Leucadia Asset Management LLC and $26.1 million on Cantor Group V, LLC, against which the bank filed a lawsuit in 2025 alleging fraud by the borrower, as disclosed in its 2025 10-K. The provision for loan losses was $213 million in that quarter alone, against $224 million for all of 2025. Even so, first-half 2026 profit was about 5% above the first half of 2025, because net interest income grew about 16%. The second quarter had no comparable large charge-offs, carried a loan-loss provision equal to about 0.5% of loans a year, and still earned at a rate well above $7.98 a share. The normal level therefore already absorbs today's higher credit costs, and we see no evidence to lower it. We also do not raise it on one or two good quarters. Growth, and what it costs. A bank cannot grow for free: every extra dollar of loans needs extra shareholder capital behind it. We credit only growth the bank has shown it can fund from its own earnings, which it did through both 2020 and 2023. Loans grew 9% and tangible book value per share grew 13% in the year to June 2026, while the bank still bought back shares. In every growth year, we charge the capital that growth needs, assuming new business earns about 12% on equity, in line with recent years. Growth slows in the second five years of each case. The bank crosses $100 billion of assets about now, which brings stricter federal capital, liquidity and stress-testing rules. The company says much of the compliance cost is already in its expense base, but the extra capital and liquidity the rules require will lower returns on new growth. After year 10, earnings in every case stay flat and are fully available to owners. They continue at all because of a deposit franchise and charter built over three decades and specialty businesses with long records. Base case. Earnings start at the $7.98 normal level and grow 4% a year for five years, then 2% for five more. About a third of earnings is kept back to fund that growth. Growth-path check: owner earnings actually rose 22% in 2025, while year one of the base case grows 4% from a level below what 2025 produced, so the case does not lean on recent momentum. The business is worth about $152.45 a share. Bear case. A credit downturn hits the bank's commercial real estate loans, including office loans on which charge-offs are already running, and its specialty lending. At the same time, deposit costs rise again. Uninsured deposits rose to $22.9 billion, about 30% of the total, at the end of 2025, up from $17.6 billion a year earlier. A further $25.1 billion of deposits come with rate-linked earnings credits and referral fees, which make funding costs jump when rates or confidence move. These are the weak points a confidence shock exposed in 2023. In this case owner earnings fall to about $2 a share in the first year, $4 in the second and $5.50 in the third. That implies roughly $1.7 billion of extra pre-tax loan losses, about 2.9% of the $61 billion loan book. Earnings then settle at $6.30 with no growth. That is the 2024 trough of $7.03, less an allowance for large charge-offs in the lending-to-finance-companies book recurring at about two-thirds of the pace seen from August 2025 to March 2026. Earnings stay positive in every year, so the losses are absorbed without new capital. The business is worth about $98.22 a share. Bull case. Earnings start from the $8.55 level the business actually reached in 2025. They grow 7% a year for five years and 4% for five more. That is below the loan and book-value growth the bank delivered in the year to June 2026, with over half of earnings kept back early on to fund it. After year 10 they are flat. The business is worth about $184.55 a share. What ranks ahead of common shareholders. For a bank, deposits, Federal Home Loan Bank advances and subordinated debt are the raw material of lending. Their interest is already paid inside the earnings above, so we do not subtract them again. Two preferred stocks do rank ahead of the common. The first is $300 million of the company's Series A preferred. It paid 4.25% until September 30, 2026, then resets every five years to the five-year Treasury rate plus 3.452%, and it can be redeemed at par on any dividend date, so we count it at its $300 million face value. The second is $300 million of 9.5% Series B preferred issued in March 2025 by a bank subsidiary, first redeemable in March 2030. Because the Series B costs well above our 6% rate until then, we add about $32 million for that extra cost. Together these claims come to about $632 million, or $5.85 a share. After those claims, common shareholders are worth about $92.37 a share in the bear case ($10.6 billion business, less $0.63 billion = $10.0 billion), $146.60 in the base case ($16.5 billion less $0.63 billion = $15.8 billion) and $178.70 in the bull case ($19.9 billion less $0.63 billion = $19.3 billion), on about 108 million diluted shares. All cash flows are discounted at a flat 6%, the same rate for every company. What changed since our last estimate. The base and bull values are essentially unchanged. The small differences come from timing the capital kept back for growth in the same year as the growth. The bear case is lower, at $92 versus $103. Our previous estimate did not account for the second large charge-off, Leucadia Asset Management in the first quarter of 2026, or for nonaccrual loans rising to $562 million (0.92% of loans) at June 30, 2026 from 0.76% a year earlier. Two large losses on loans to finance companies within about eight months are a pattern, not a one-off. We now assume such losses keep recurring in a bad outcome. What would make this wrong. A credit downturn much deeper than the bear case could force the bank to raise capital and dilute existing shareholders, especially one concentrated in office and other commercial real estate or in the specialty lending books, or further large losses on loans to finance companies. A second deposit run could do the same. On the upside, if growth after crossing $100 billion stays near the pace of the last year, the business would be worth more than we credit. Margin-of-safety price. This is a leveraged, credit-cyclical bank that has been through one deposit run and two recent large charge-offs. Bank shares can also stay well below the value of their earnings for years. So the price is set to work even if recognition is slow. The margin-of-safety price is $80. From $80, a 20% yearly return including dividends requires the shares to reach base-case value within about five years, or bear-case value within about a year. At $80, the shares would also sit about 13% below the bear-case value.
