Is AT&T an Undervalued Dividend Stock to Buy for Passive Income Investors? | T Stock Analysis

Parkev Tatevosian, CFA•Sep 28, 2026

Summary

Parkev provides a comprehensive analysis of AT&T, focusing on its transition into a leaner, more efficient company following major divestments. Parkev highlights that although total revenue decreased from $185 billion to $127 billion, this reflects a strategic move to shed non-core businesses and reduce debt. Parkev emphasizes that operating margins have improved significantly from 17.5% in 2017 to 21% today, partially due to the successful integration of AI, which reduced some technology costs by 90%.

Parkev notes that the telecommunications market is largely saturated, with growth driven by increasing revenue per user rather than new customer acquisition. Parkev points to the upcoming iPhone upgrade cycle and foldable devices as potential short-term catalysts for customer retention. However, Parkev cautions investors about the company's historically mediocre return on invested capital (ROIC) of 8.11% and the looming capital requirements for the 6G network cycle.

Regarding valuation, Parkev mentions that the stock trades at a forward P/E of 9.9x, which Parkev considers fair for the industry. However, using a Discounted Cash Flow (DCF) model, Parkev calculates a fair value of $34.60 per share, which is significantly higher than the current market price of approximately $25.50.

AT&T (T): Parkev views the stock as a buy with medium conviction, citing its 4.4% dividend yield and improving profit margins. Parkev notes that while the company faces high infrastructure costs for 5G and 6G, its operational efficiency is trending upward. Parkev's DCF analysis suggests the stock is undervalued, with a fair value target of $34.60 compared to the current $25.50 price level.

Parkev is impressed by the expansion of operating margins to 21% and the company's ability to use AI to cut costs.
