Is TBB overvalued in 2026?
AT&T Inc (TBB) currently trades at $21.57 per share with a market capitalization of $132,864,836,000.00. Based on our multi-factor framework, the stock appears richly valued with a Smart Value Score of 25/100. This score blends growth quality, financial health, and price attractiveness into a single institutional-grade read.
The stock trades at a P/E ratio of 4.2x, below its 5-year median of 7.3x.
Looking at its own history, TBB is currently trading cheaper than 73% of the last 5Y on P/E. This places it in the 27th percentile of its historical range, a reasonable but unremarkable position.
A standard DCF model does not produce reliable output for TBB under current conditions. For unprofitable or near-breakeven companies, revenue-based multiples such as EV/Sales and historical P/S percentile are more informative than intrinsic value calculations.
The Piotroski F-Score of 5/9 puts financial quality in a middling range, neither a standout strength nor an obvious red flag.
Bottom line: TBB appears richly valued on our framework, with a Smart Value Score of 25/100. At current levels the risk/reward is skewed against the buyer. A materially lower price or significant operational improvement would be needed to change the picture.
