Banco Santander (BME:SAN) shares rose to a fresh 52-week high on Wednesday, closing up 0.85% at €12.75 after touching an intraday peak of €12.798. The move came as the Spanish banking giant received the final regulatory green light for its $12.2 billion acquisition of Webster Financial Corporation (NYSE:WBS), with the Federal Reserve's approval clearing the last major hurdle.
The transaction, which represents roughly 4% of Santander's total assets, is now slated to close on August 20. It had already secured approvals from the Office of the Comptroller of the Currency (OCC) and the European Central Bank. With regulatory uncertainty out of the way, the investment thesis now hinges on execution and the promised financial benefits.
Deal Economics and Synergies
Santander management projects the acquisition will deliver 7%–8% group earnings per share (EPS) accretion by 2028, a figure that is roughly 1.75 to 2 times Webster's share of assets. The combined U.S. balance sheet is expected to total approximately $327 billion, comprising $185 billion in loans and $172 billion in deposits. Executive Chair Ana Botín has described the two banks as “a perfect match.”
Key financial targets include reducing the U.S. loan-to-deposit ratio from 109% to around 100%, a nine-point improvement that should lower funding costs. The company also aims for $800 million in annual pre-tax cost savings by the end of 2028, representing 19% of the combined expense base. Return on invested capital is targeted at near 15% by 2028.
Capital Impact and Market Reaction
The deal will dent Santander's capital position. The group's CET1 ratio, which stood at 14.0% in June, is expected to fall to approximately 12.8% after closing, a reduction of 120 basis points. Despite this, the company has some flexibility, having reported a 15% rise in underlying first-half profit to €7.33 billion and a group return on tangible equity (RoTE) of 15.6%.
Jefferies analysts commented that “NII dynamics look strong, and so do costs,” underscoring optimism about the bank's core operations. However, the average analyst price target of €13.04 implies just 2.3% upside from Wednesday's close, suggesting that much of the good news is already priced in.
Sector and Peer Movement
Spanish bank shares were mixed on the day. BBVA (BME:BBVA) fell 1.26%, while CaixaBank (BME:CABK) gained 1.03% and Sabadell (BME:SAB) slipped 0.15%. Santander's stock has risen 6.7% since late July, extending a five-session winning streak.
Risks and Watch Items
Provisions rose 13% in the second quarter to €3.35 billion, and any deterioration in credit quality or a slowdown in savings could erode the modest upside. Investors will also monitor upcoming economic data from key markets, including U.S. inflation (August 12), UK GDP (August 13), and euro-area industrial production (August 13).
With the Webster deal set to close next week, the focus now shifts to delivering on the promised cost savings and EPS accretion. The $800 million annual cost reduction target by 2028 remains the more challenging hurdle.
