Swansea City AFC has returned to the portfolio of Levy UK + Ireland, the sports and entertainment division of Compass Group UK & Ireland.
The business said regional sourcing and sustainability credentials were fundamental to the "long-term" contract, although the exact length and value of the contract were undisclosed. Sodexo held the contract for the last five years.
Levy previously worked with Swansea City when the stadium was opened in 2005, and will provide matchday experiences, plus conference and events catering. Its portfolio also includes Cardiff City Stadium and the Principality Stadium.
Self-order units will be installed in time for the start of the 2023/24 season. Increasing plant-based menu options, reducing single-use plastics and food waste will all be priorities for the foodservice operator.
Compass Cymru managing director, Jane Byrd, who oversees all Levy sites based in Wales, said: "It's brilliant to have Swansea City back in our portfolio, cementing our stadia business in Wales. We love partnering with like-minded businesses and we know how important it was for Swansea City to work with a partner who has serious Net Zero ambitions.
"Bringing together our green credentials and commitment to providing quality Welsh produce is an exciting prospect and we couldn't be happier to be working together again. Through our catering partnership with Swansea University, we have some established relationships which will work well with the Swansea City fanbase."
Swansea City chief executive, Julian Winter, added: "We're delighted to be back in the Levy UK+I fold and pleased to be benefitting from the regional expertise that comes with Compass Cymru; they are not only specialists in stadia catering, but catering in Wales.
"Finding a partner committed to working towards a greener future is very important to us at Swansea City. We continue to make progress in our desire to operate in a more environmentally friendly manner, whilst striving to deliver the best possible produce and service for our supporters. We look forward to reaching our goals on all these fronts through this long-term partnership with market-leaders Levy UK + Ireland."
