T-mobile insiders dump $151 million in shares amid stock decline
T-Mobile's stock is taking a beating, and it's not just the market. A wave of selling by company insiders, including Harvard Business School Dean Srikant Datar, is raising eyebrows and fueling concerns about the carrier's future.

Insider sales surge as t-mobile stock slides
Datar recently sold 1,000 shares of T-Mobile on March 10th for $218.25 each, netting a gross of $218,250. But that's just the tip of the iceberg. Over the past month, Datar offloaded a total of 4,291 shares, totaling $945,890.
This isn't an isolated incident. Former CEO Mike Sievert, still on the board, unloaded 80,000 shares worth $17.2 million. Director Raul Marcelo Claure sold a staggering 550,000 shares, realizing $119.6 million. Since February, insiders have collectively sold nearly $151 million worth of T-Mobile stock, dwarfing any buying activity.
The timing is particularly concerning. These sales are occurring near T-Mobile's 52-week high, suggesting insiders are capitalizing on inflated prices. Many of Sievert’s sales appear to have been executed under a 10b5-1 trading plan, pre-arranged sales designed to avoid accusations of insider trading based on non-public information.
The question now is whether this widespread selling signals a deeper issue with T-Mobile's strategy. The company's recent decision to halt quarterly postpaid net phone ad reporting – a key metric used by analysts to compare performance with rivals like Verizon and AT&T – has fueled speculation that the carrier knows its shift towards a digital-first model is faltering.
Analysts have questioned the wisdom of reducing physical stores and pushing all transactions through the T-Mobile app, fearing a potential subscriber exodus. The stark imbalance between selling and buying activity paints a worrying picture. Over the last year, T-Mobile shares have fallen 15.08%, or $38.59.
While some insider selling can be attributed to diversification or planned sales, the sheer volume of disposals, particularly from prominent figures like Datar and Sievert, raises serious questions. The narrative of a successful transition to a digital carrier is increasingly fragile.
The data speaks for itself: confidence in T-Mobile's trajectory is eroding from within.
