Marathon Asset Management unifies platform 

London, June 3, 2026 — Marathon Asset Management (“Marathon”), a London-based specialist equity manager with over USD 40 billion in assets under management, has consolidated its front-to-back investment infrastructure on SimCorp One, retiring legacy systems and establishing a single data layer across the firm.  

The move extends a partnership that began in 2010 and supports Marathon’s continued focus on operational efficiency, data consistency, and scalable investment operations. The successful implementation was delivered through close collaboration between Marathon and SimCorp. It enables Marathon to spend less time on data reconciliation and technology management, and focus more on client service and investment decisions guided by the firm’s Capital Cycle investment philosophy.

“SimCorp understands both our operational and front office needs, which made unifying our front-to-back workflows on a single platform a clear decision,” said Andy Flawn, Head of Operations, Technology, Change and Data, Marathon Asset Management. “Lowering cost and risk through system consolidation was a key factor. Our partnership continues to deliver meaningful technology improvements that drive operational efficiency.”

“We’re proud to deepen our long-term partnership with Marathon,” said Dean McIntyre, Chief Commercial Officer, SimCorp. “SimCorp One automates key processes across the investment lifecycle, giving Marathon the operational efficiency to scale.”  

Marathon’s decision reflects a wider shift among asset managers. SimCorp’s 2026 InvestOps Report found that consolidating technology vendors and platforms is the top priority for 58 percent of investment managers globally. Recent selections of SimCorp by asset management firms include Pictet Asset Management, AllianceBernstein and Lindsell Train.
