NORTHERN TRUST CORP (NTRS) stock intrinsic value fair value estimate & owner earnings analysis

Northern Trust is a Chicago trust bank, founded in 1889, that earns most of its money from fees rather than lending. Its Asset Servicing business holds and administers assets for pension funds, sovereign wealth funds, endowments, insurers and fund managers ($17.4 trillion of assets under custody or administration at December 31, 2025), and its Wealth Management business serves wealthy families, business owners and family offices ($1.3 trillion under custody or administration). It also manages money for both groups. Fees from these clients were $5.02 billion in 2025, and net interest income from client deposits was another $2.41 billion. About 30% of 2025 revenue came from outside the United States. How we measured earnings. We count the cash the business generates for shareholders: net income plus non-cash charges such as depreciation and software amortization, minus share-based pay and the spending needed to keep the systems running (most of the investment here is software). We take out swings in collateral and other balance-sheet flows, which dominate a bank's cash-flow statement, and we strip out one-time items, mainly the gains from exchanging Visa shares in 2024 and again in the second quarter of 2026 ($525 million before tax). On that basis owner earnings per share were $7.09 in 2018, $6.29 in 2020, $7.40 in 2021, $5.39 in 2023 and $9.66 in 2025. Those per-share figures move with interest rates and expenses, and the business has also grown, so we did not simply take the middle of the per-share series (about $6.70), which would describe a smaller company. Instead we took the typical share of revenue that turned into owner earnings across 2018 to 2025, a period that covers rising rates, near-zero rates in 2020 and 2021, the 2022 rate shock and two stock-market falls. That share ranged from 16.1% (2023) to 26.7% (2018), with a midpoint of 22.2%. Applied to 2025 revenue of $8.09 billion, it gives about $1.79 billion, or $9.32 per share on 2025's 192 million diluted shares. One adjustment goes against the company. Northern Trust has repeatedly sold low-yielding bonds at a loss so it can reinvest at higher yields: $213 million of losses in 2022, $170 million in 2023, $189 million in 2024 and another $74 million in the second quarter of 2026. The higher yields that follow show up in later interest income, so we treat these losses as a recurring cost rather than a one-off. They average about $0.56 per share after tax, which brings the base starting point to $8.76. Debt. For a bank, deposits and short-term borrowing are the raw material of the business, not financing to be paid off, so we value earnings after interest and do not subtract them separately. The risk of the balance sheet ($177.1 billion of assets against $13.0 billion of equity at the end of 2025) is carried in the bear case. Capital is comfortable: the Federal Reserve's minimum common equity ratio for the company was 7.0%, including a 2.5% stress buffer, for the year to September 30, 2026, and the Fed has said the buffer will stay at 2.5% until September 30, 2027. The company reported a ratio of 14.3% under the advanced approach at June 30, 2026. We do not add any of that surplus to the value. Final Basel III capital rules were not settled when the 2025 annual report was filed, and they could change how much of that surplus is truly free. Bear case, about $88 a share. Earnings fall back to their 2023 low of about $1.12 billion, less the recurring bond-sale losses, and stay there permanently with no growth, which is $5.26 a share. The evidence for this path is already in the record: net interest income was only $1.38 billion in 2021, when rates were near zero, against $2.41 billion in 2025, and from 2022 to 2024 the share of revenue reaching owners fell to between 16% and 19% as costs rose. A combination of lower rates and renewed cost pressure would put the business back there. Base case, about $167 a share. Earnings start at $8.76 and grow 2% a year for ten years to about $10.47, then hold flat. Fee revenue has compounded about 4.9% a year from 2017 to 2025. That record includes the 2020 market drop, when fees still rose, and 2023, when they fell only 1.6%. We credit less than half that pace because part of the record came from rising market values, which we do not count on. In 2025 owner earnings per share grew 39%, from 2024. We assume only 2% for the first year, well below that. After year ten we hold earnings flat rather than letting them fade. Custody and administration relationships are built into clients' daily operations and tend to last for many years, and the franchise has run for more than a century, so the earning power is structural. Bull case, about $199 a share. Earnings start from 2025's actual $9.66, less the bond-sale losses ($9.10), and grow 4% a year, still below the demonstrated fee growth rate, to about $12.95 in year ten, then hold flat. Recent results point this way: in the first half of 2026 fees rose 10% and net interest income 13% from a year earlier, and even after removing the second-quarter Visa gain and that quarter's charges (bond losses, $61.5 million of software disposals, $51.0 million of severance and a $33.1 million one-time employee stock grant), earnings ran clearly ahead of the first half of 2025. One strong half-year does not by itself justify a higher starting level, so it informs only this case. Shareholder returns. The company declared $3.10 a share in dividends in 2025, raised the quarterly dividend from $0.80 to $0.88 in mid-2026, and spent $1.27 billion on buybacks in 2025. Diluted shares fell from 207.6 million in 2023 to 192.2 million in 2025 and 185.7 million in the first half of 2026. We value the cash these payouts come from, not the buybacks themselves, so the share-count decline is not counted as extra growth. Margin-of-safety price. The margin-of-safety price is $100. At that price the bear case sits about 12% below it, and the base case is about two-thirds above it plus a dividend yield above 3%. Reaching the base value within about three years implies roughly 20% a year. Above $100 the gap between bear and base is too wide to rely on that return. Change from our previous analysis. Our earlier estimates were $77, $170 and $238 with a $119 margin-of-safety price. We now use the same 6% discount rate for every company, value only growth we can point to in the record, and no longer add surplus capital on top. We start from a higher, margin-based earnings level but charge the recurring bond-sale losses and credit slower growth. The net effect is a higher bear value, a similar base value, a lower bull value and a lower margin-of-safety price. In June 2025 there were reports of a merger approach from BNY, and Northern Trust said it intends to stay independent. No deal is assumed in any case. What would make this wrong: a long return to near-zero interest rates combined with weak markets would push results toward or below the bear case, while a final Basel III rule that demands much more capital would limit buybacks and dividends. On the other side, the 2026 earnings level could prove durable, which would put fair value nearer the bull case.
