British supermarket chain Asda has appointed Cal Corcoran as group chief information officer.

Corcoran is due to take up the role on 5 January 2026, with responsibility for overseeing Asda’s technology and data functions.

He will lead the retailer’s technology and data teams as the company continues to operate as a standalone business following its separation from Walmart.

The appointment follows the completion of Asda’s separation programme from US retailer Walmart, with the supermarket now concentrating on developing and fine‑tuning its own systems.

Asda said Corcoran arrives with over 25 years of senior IT leadership experience, spanning a wide range of industries such as technology, financial services, civil aviation, oil and gas, telecommunications, and the aerospace and defence sectors.

He has held high-level technology leadership roles across a range of major organisations, including Microsoft, Barclays, Gatwick Airport, BP and Castrol.

The company said Corcoran has experience leading IT transformation and delivery in complex operating environments.

He will use this expertise to guide Asda’s technology and data operations as the retailer continues to build out its own independent infrastructure.

Asda executive chairman Allan Leighton said: ​“Our use of data and technology is a critical element of our business that enables us to show up for our customers in the ways they expect. I'm delighted that Cal is joining the senior leadership team as we double down on our formula for growth as we head into 2026, and I look forward to welcoming Cal to the business next week.”

Earlier this month, Asda reported a decline in underlying sales for the Q3 in 2025, attributing the downturn to widespread operational disruption following a major technology overhaul.

Total revenues excluding fuel for the quarter came in at £5.1bn ($6.76bn), with like-for-like sales down 2.8%.

In a trading update, Asda stated that performance in the period was hit by “severe disruption” to its systems after the cutover from Project Future, which “materially impacted” trading.
