What could change its growth trajectory, and what would confirm it?
Store expansion could extend Dia Spain's growth: the 94 stores opened during 2025, 36 of them in the fourth quarter, accompanied faster-than-market growth of 8.6% to €5.6 billion and a 20-basis-point market-share gain versus the same period last year, and repeat gains would confirm the driver.
The company, Dia Spain, posted a 0.6-percentage-point rise on the previous year.

What is the investment case, and what must be true for it to hold?
Grupo Dia can build on Spanish like-for-like sales growth of 7.4% with a 67% franchise network, and on outpacing the overall market with a 20 basis-point share increase versus the same period last year, provided it sustains those gains; Mercadona's much larger market share is the main threat to that thesis.
Mercadona holds a 27% market share, exceeding Carrefour, Lidl, Eroski, Dia, and Consum combined, while DIA held a 3.8% market share in November 2025 according to Worldpanel by Numerator.
