Internet Initiative Japan Inc. (3774.T) fair value

ACCE thesis

Internet Initiative Japan (IIJ) runs one of Japan's older commercial internet backbones, selling managed network services, cloud and data center capacity, and security operations to enterprises and public-sector clients, alongside its consumer broadband and mobile resale business. Its edge is incumbency in enterprise network integration: long-running contracts and a service mix that spans connectivity, colocation and managed security give it sticky revenue that competitors selling bandwidth alone struggle to match. Revenue grew 27.1% over the latest reported period, and trailing earnings support a 25.6x P/E against a 25.0x forward multiple, so the market is paying for growth that management still has to convert into earnings. Operating margin of 6.8% and gross margin of 21.1% are thin for a services business, which makes the margin trajectory of the cloud and security lines the key thing to check. With ROE at 16.3%, the question for a deeper look is whether the top-line momentum is coming from high-margin managed services or from lower-margin pass-through revenue.
