Banco Santander (SAN) Q1 2026 earnings review

ONE Transformation Drives Record Profitability Through Positive Jaws

Banco Santander delivered a stellar Q1 2026, reporting an attributable profit of €5.45 billion. While this headline figure was heavily inflated by a €1.89 billion capital gain from the disposal of its Poland business, the underlying core operations tell a compelling story. Underlying profit rose 14% YoY in constant euros to €3.56 billion. The bank successfully executed 'positive jaws'—revenue grew 6% while costs declined 1% in constant euros, compressing the efficiency ratio by 300 basis points to 42.8%. Despite specific headwinds from UK Motor Finance litigation and US EV tax benefit expirations, the group's highly diversified model and strict capital discipline generated an outstanding 15.2% underlying RoTE.

🐂 Bull Case

Cost Efficiency Realized

The ONE Transformation strategy is actively lowering the cost-to-serve. Operating costs fell 1% YoY in constant euros against a backdrop of 6% revenue growth, rapidly driving down the efficiency ratio toward the 2028 target of ~36%.

Unmatched Organic Capital Generation

CET1 ratio surged to 14.4% (aided by the Poland sale), but more importantly, organic capital generation continues to outpace distribution. New front-book RWA is being written at a highly accretive 21% RoTE.

🐻 Bear Case

Pockets of Credit and Regulatory Risk

The €155M net provision for UK Motor Finance and deteriorating macro-driven LLPs in Argentina highlight persistent regional tail risks that drag on overall group credit metrics.

One-Off Headwinds in Growth Segments

Openbank US profit was directly suppressed by €81M due to the expiration of EV fiscal benefits, questioning the near-term organic profit trajectory of the US auto lending portfolio without tax subsidies.

⚖️ Verdict: 🟢

Bullish. The strategic thesis is playing out perfectly in the numbers. When a massive global bank proves it can grow revenues in mid-single digits while actively shrinking its nominal cost base, it unlocks immense operational leverage. The massive 14.4% CET1 provides a massive buffer for future buybacks.

Key Themes

DRIVER🟢🟢

ONE Transformation Yielding Operational Leverage

Santander's structural overhaul is no longer just a narrative; it is visible in the P&L. Total costs decreased 1% YoY in constant euros, reducing the cost per active customer to €253. The efficiency ratio compressed 300 basis points YoY to 42.8%. Management is effectively keeping the incremental cost for growth at €0 by shifting contact centers to digital self-service and leveraging common cloud architectures.

DRIVER🟢

Fee Income and Diversification Absorbing Rate Headwinds

Despite a less favorable interest rate environment for pure lending, Net Fee Income grew 7% YoY to €3.35 billion. This was heavily supported by Corporate & Investment Banking (CIB), which delivered a 21% RoTE, and Wealth Management, where Assets under Management (AuMs) grew 10% to €545 billion. This highlights the resilience of the global, multi-segment model.

DRIVER🟢

Capital Productivity and Disciplined Allocation

Capital allocation has tightened significantly. Santander reported that 89% of RWAs currently generate a Return on RWA (RoRWA) greater than the Cost of Equity. Furthermore, new front-book business was priced at a 21% RoTE. This discipline allowed the bank to organically generate 29 bps of capital, driving the CET1 ratio to 14.4%, well above the 12.8-13.0% 2026 target range.

CONCERNNEW🔴

UK Motor Finance Litigation Provisions

The ongoing regulatory scrutiny of historical motor finance commission payments in the UK finally materialized on the P&L. Openbank Europe recognized an additional €207M gross (€155M net of tax) provision. While the bank is highly capitalized, this introduces regulatory tail risk and impacts the net profitability of the Openbank segment.

CONCERN🔴

Argentina Macroeconomic Drag

Hyperinflation and sector-wide macroeconomic deterioration in Argentina continue to heavily distort group credit metrics. Total Group Cost of Risk (CoR) increased 2 bps to 1.14%. However, excluding Argentina, CoR actually improved by 2 bps to 1.08%, and LLPs were down 2% YoY. Until the Argentine market stabilizes, it will remain a persistent anchor on consolidated asset quality.

CONCERNNEW🔴

Expiration of US EV Fiscal Benefits

A specific headwind hit the US operations this quarter. Openbank US profit was negatively impacted by an €81M charge resulting from the end of electric vehicle (EV) fiscal benefits. While Openbank US PBT was up 9% excluding the UK Motor Finance charge overall, the loss of this tax shield poses questions regarding the unit's organic margin profile moving forward.

THEMENEW🟢

Artificial Intelligence Monetization

Santander is aggressively moving AI from an experimental concept to a P&L contributor. The bank reported that its AI initiatives—focused on maximizing cross-selling and 'agentic commerce'—generated €35M in direct business value in 26Q1 alone. The bank targets >€1 billion in value generation from AI between 2025 and 2028.

Other KPIs

Net Interest Income (NII)€11.02 billion

NII grew 5% YoY in constant euros. The growth was supported by solid lending volumes across Retail (+2% YoY) and Openbank (+6% YoY), counterbalancing slight margin compressions in some retail markets due to falling central bank rates.

Payments Segment Underlying Profit€20 million

While small in absolute terms, this represents a massive 288% YoY increase (+4x vs Q1'25). Driven by global scale platforms (Getnet), the cost per payment transaction collapsed 47% YoY. EBITDA margin expanded 4.8 percentage points to 33.4%.

Tangible Net Asset Value (TNAV) + Cash DPS+19% YoY

A key measure of total shareholder value creation. TNAV per share reached €6.48. This growth is underpinned by both strong organic earnings retention and aggressive capital return programs, including ongoing share buybacks.

Guidance

2026 Total RevenueMid-single digit growth

Stable. The bank expects to maintain the trajectory seen in Q1 (+6% in constant euros), relying heavily on fee generation and volume growth to offset potential rate cuts.

2026 Total CostsDown in constant euros

Accelerating efficiency. Management expects absolute costs to be lower than the €14.1 billion reported in 2025, demonstrating immense confidence in the cost-out trajectory of the Gravity platform migrations.

2026 CET1 Ratio12.8% - 13.0%

Decelerating. With CET1 currently sitting at a highly elevated 14.4% following the Poland disposal, the guidance implies significant capital consumption ahead. This will primarily be driven by the closing of the TSB (~60 bps) and Webster (~150 bps) acquisitions, plus planned distributions.

Key Questions

UK Motor Finance Liabilities

With the €155M net provision taken this quarter in Openbank Europe, do you consider this the final ring-fenced liability for the UK Motor Finance FCA review, or are we awaiting further industry-wide redress scheme clarity before drawing a hard line?

US Auto Lending ex-EV Subsidies

The €81M hit from the expiration of US EV fiscal benefits was substantial. How should we model the run-rate profitability and margins of the US auto portfolio without these structural tailwinds?

Acquisition Integration Risk

With the ONE Transformation program operating at maximum velocity, how do you plan to safely integrate two major parallel acquisitions (TSB and Webster) in H2 2026 without disrupting your aggressive internal cost-cutting targets?

Argentina De-risking

Given the persistent drag of Argentina on the consolidated Cost of Risk, what specific measures are being taken to de-risk the balance sheet locally, and at what point does the capital allocation there become difficult to justify?
