UNIT vs MGNI Comparison

Uniti is the product of the August 2025 merger of the firm with Windstream, its former primary customer. The combined firm owns a 240,000 route-mile fiber network that serves enterprise and residential customers. Selling high-capacity fiber circuits to enterprises generates about 20% of consolidated revenue. Uniti's residential networks reach about 4.5 million households, mostly in less-populated markets in the Southeast, but only about 1.9 million of these locations have been upgraded with fiber. Legacy copper-cable networks serve the remainder. Residential services account for about a third of total revenue. Small business and wholesale services provided within this residential service territory account for about 20% of revenue.

Magnite is a supply-side advertising platform that provides technology and yield management solutions to content publishers, enabling them to monetize their digital advertising inventory. Magnite receives a percentage of all advertising inventory that it sells. 43% of Magnite's revenue is derived from connected television, or CTV, streaming platforms, 40% from mobile applications, and the remainder from general websites. Beyond the typical monetization responsibilities inherent to an SSP, Magnite also provides upstream advertising servers to CTV publishers, allowing them to have granular control over direct-sold, programmatic guaranteed, and open-auction logic. Magnite competes with other independent SSPs, supply path optimization solutions, and closed ecosystems like Meta.
