T-Mobile's gross margins hit a decade low of 42.5% while insiders sold $1.3B — growth at any cost has become costly indeed.
T-Mobile demonstrates the perils of growth at any cost — sacrificing unit economics and leveraging the balance sheet to chase market share in a maturing industry.
A truly great business must have an enduring moat that protects excellent returns on invested capital.
This framework sees a moat under severe pressure. While the 65.6% concentration in branded postpaid creates switching costs, the collapse in gross margins to decade lows suggests pricing power has evaporated. The business trades margin for growth, indicating commoditization rather than competitive advantage.
Owner earnings are the cash an owner gets to keep after maintaining the business.
Applying this lens reveals a paradox — exceptional cash generation despite deteriorating unit economics. The company extracts elite levels of cash while gross margins hit historic lows, suggesting operational efficiency that may not be sustainable.
We like to do business with someone who loves his company, not just the money.
This framework finds troubling stewardship. Management's persistent selling while executing value-destroying buybacks at peak prices reveals poor capital allocation. The $1.3B in insider sales over 15 quarters suggests those who know the business best lack confidence in its future.
If you bought this entire business today, would what it earns justify what you paid?
The owner's math presents mixed signals. While the DCF suggests significant undervaluation, the 0.93% earnings yield means an owner earns less than risk-free treasuries. This framework sees a business where growth expectations have reset dramatically but valuation remains rich for a permanent owner.
Applying the Buffett framework reveals a business generating exceptional cash flow through operational excellence while destroying its economic moat through margin compression and poor capital allocation. The combination of decade-low gross margins, peak leverage, and management's $1.3 billion exodus suggests this is not a business Buffett would admire. Would you want to own a company where insiders are rushing for the exits while margins collapse to historic lows?
