Rewards

MRK

  • Each dollar of retained earnings has created $4.94 of earning power — management is an exceptional capital allocator.
  • Management has timed buybacks well — 2 out of 3 years showed value-accretive repurchases.

  • Texas Instruments Incorporated has maintained ROIC above 15% for 4 consecutive years, indicating a durable competitive advantage.
  • Return on equity has consistently exceeded 20% over 4 years, indicating efficient use of shareholder capital.
  • Altman Z-Score of 8.73 indicates very low bankruptcy risk — the company is firmly in the safe zone.

Risks

MRK

  • 14 insider sales with no purchases over the past 12 months — a persistent pattern of insider selling.
  • Free cash flow has declined at a 5.6% CAGR over the past 4 years — a concerning trend.
TXN
