"Diameter's 4Q25 letter candidly details a painful distressed loss in First Brands due to fraud, while outlining a cautious but active 2026 playbook focused on bespoke capital solutions, AI power-infrastructure constraints, and rising risks in the asset-backed finance market."
Diameter Capital Partners reported a +0.3% net return for the Diameter Master Fund in 4Q25. The letter outlines significant performance headwinds from legacy distressed positions, specifically EyeCare Partners and a severe loss in First Brands due to extensive accounting fraud. Despite these challenges, the firm succeeded in credit investments like EchoStar, Signature Bank bonds, and Credit Suisse AT1s. Looking ahead to 2026, the firm highlights critical investment themes including Chinese overcapacity in chemical markets, grid-capacity constraints affecting AI datacenters, the rapid and potentially sloppy growth of Asset-Backed Finance (ABF) driven by insurance annuity demands, and a highly bifurcated US consumer landscape.
