KeyBanc Capital Markets downgraded T-Mobile from sector weight to underweight, citing concerns about the carrier being 'fiber deficient in a converged/bundled world.' Their analysis indicated issues with T-Mobile’s fiber infrastructure and consumer value following recent pricing changes, raising concerns of customer churn. The downgrade was influenced by expectations that T-Mobile would benefit less than peers from potential tax changes due to the OBBB (Optimized Broadband Buildout Benefits). This change comes on the heels of T-Mobile’s launch of its Fiber Home Internet service, promising a five-year price guarantee.
