The contract covers a range of pre-media services, such as page makeup, image manipulation and retouching, as well as FMG's VIP4 flatplanning and production software.
Under the terms of the agreement, Islington-based FMG will also continue to provide asset management services to support Haymarket's global licensing and syndication operations.
FMG managing director Andy Berg said: "We have enjoyed a particularly special relationship with Haymarket for many years now and they remain one of our most valued clients.
"We consider it a privilege to be asked to continue to support them as they are unquestionably one of the UK's most well-respected and successful private publishers."
Haymarket Media Group chief executive Kevin Costello added: "FMG has been one of our most trusted and reliable suppliers for nearly two decades now.
"I'm pleased to award them this new contract and look forward to us working together in the future."
In addition to their historic pre-press relationship, the two companies have been increasingly working together on digital and video- related projects.
The army's interactive magazine, Camouflage, was the result of a joint collaboration between FMG's digital team and Haymarket customer publishing agency Network, for its client the British army.
