In 2026, Dia will significantly strengthen its local sourcing strategy in the dairy sector, implementing a business plan that includes purchasing approximately 200 million liters of milk from Spanish suppliers. This move will be accompanied by a clear decision on the supply side, namely to ensure that 100% of the own-brand milk sold in its stores is of domestic origin.
This approach is part of a trajectory already underway in recent years and is expected to accelerate further in 2026, with an increase of approximately 4% in Spanish milk volumes compared to the previous year. This demonstrates a strategy that aims to combine perceived quality, supply chain transparency, and concrete support for the local livestock sector.
In this context, milk continues to be a key product in Spanish household food expenditures, not only for its nutritional value—thanks to its calcium, protein, and vitamins—but also for its versatility within the daily diet, maintaining a central role across all consumer groups and ages.
Economically, the company's commitment translates into a total investment of approximately €180 million earmarked for 2026 for the purchase of 100% Spanish-sourced milk, including €117 million for private label products. This represents a strategic lever that strengthens the company's ties to the local area and helps support the stability and profitability of the national agricultural and industrial supply chain.
In terms of production geography, Galicia remains the main supply hub with approximately 100 million liters, followed by other key areas such as Castile and León, Catalonia, Asturias, and the Basque Country. This complex map reflects the distribution of dairy production across the country and the ability of modern distribution to integrate with the various territorial districts.
This network is based on a structured collaboration with leading operators in the sector, including Larsa, Leyma and Feiraco in Galicia, ATO, Llet Nostra and Letona in Catalonia, Gaza in Castile and León, Kaiku in the Basque Country and Covap in Andalusia, in addition to the presence of established brands such as Asturiana, Puleva and Pascual, helping to build a solid, diversified and efficient supply chain.
Within the category, private label continues to be a key driver, accounting for approximately 65% of total milk sales and confirming the increasingly central role of private labels in large-scale retail trade strategies, both in terms of profitability and customer loyalty.
Among the best-performing products, the Dia Láctea fresh milk line stands out in particular, in the whole and semi-skimmed variants, which in 2025 recorded a growth of 37% reaching 5,6 million litres sold, highlighting a positive trend that is part of the broader trend of valorisation of fresh and short supply chain products.
At the same time, the company continues to adapt its product range to new consumer habits, with a growing presence of lactose-free products and protein-enriched variants, thus meeting a demand increasingly focused on well-being, nutritional functionality, and personalized food choices.
The entire project is part of the 2026-2029 Sustainability Plan "El valor de cada Dia," through which the company intends to strengthen its positive impact on local communities by consolidating a collaboration network that exceeds 1.100 national suppliers, who account for 96% of the total purchasing volume.
A model based on a widespread presence across the country, with over 2.300 stores and an e-commerce channel reaching 84% of Spanish households, helping to support employment, entrepreneurship, and economic development in both rural and urban areas.
Overall, the impact generated along the supply chain exceeds €7 billion and involves key sectors such as livestock farming, agriculture, manufacturing, logistics, and services, highlighting the role of modern distribution not only as a commercial channel but as a true industrial engine capable of generating widespread value and strengthening the competitiveness of the national agri-food system.
