T-Mobile's new reporting metric policy turns heads

About mid-way through T-Mobile’s two+ hour Capital Markets Day presentation, CFO Peter Osvaldik dropped a bit of a bombshell: Beginning in Q1 2026, the company will no longer be reporting postpaid phone net adds. What?!!!!! For years, this has been the metric used to gauge the growth (or lack thereof) of mobile carriers. It’s the easy button for comparing how the carriers are doing against their rivals. If one has a blockbuster quarter and another tanks, it’s right there in the net adds. The move didn’t seem to go over well among analysts who crunch numbers for a living. “Disclosure changes to subscribers—not a lot of love for that,” declared a subhead in New Street Research analyst David Barden’s note for investors.
