Insights

Banking equity analyst

Large ongoing buyback returns capital and reduces share count.

Banco Santander reports that its Buyback Programme has reached 3,756,788,259 Euros in repurchases, equal to about 74.7% of the authorised maximum. This represents a substantial capital return funded by the bank to reduce its equity base.

The bank notes that buybacks so far equal roughly 17.4% of its outstanding shares as of 2021, indicating a meaningful reduction in share count over time. Actual per-share benefits depend on future earnings and how the remaining portion of the programme is executed.

Investors can use these disclosed figures to gauge how the completed and remaining buybacks affect ownership percentages and potential per-share metrics once the programme, as described in the earlier commencement communication, is fully executed.

inside information regulatory

"notice of inside information of 4 February 2026 (official registry number 3077)"

Information not available to the public that, if known, would likely cause a company’s stock or bonds to rise or fall—for example, undisclosed earnings, deals, product results, or management plans. It matters because trading on that information gives an unfair advantage, can distort market prices, and is typically illegal or subject to strict rules, so investors watch for proper disclosure and compliance to protect fair, transparent markets.

weighted average price financial

"Number of shares | Weighted average price (€)"

Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.

own shares financial

"buyback programme of own shares (the “Buyback Programme”)"

Shares a company owns in itself are pieces of its stock that it has bought back or is holding in a treasury account instead of being owned by outside investors. For investors this matters because those held shares reduce the number of shares available on the market and can change per-share metrics and voting power—like a shop removing some items from the shelf, which alters the supply and how value is divided among remaining owners.
