Deciding what to do with AT&T's stock can feel a bit like standing at a crossroads: should you hold on, buy more, or take some gains off the table? If you have watched AT&T's performance this year, it's understandable to feel intrigued. The stock has added a remarkable 28.5% year-to-date, with a long-term track record that’s equally impressive, posting a 41.0% gain over the last 12 months and more than doubling investors’ money over three years. Recent weeks have included some smaller fluctuations, like a minor dip of -0.3% this past week, but the broader trajectory has shown strong growth. The uptick in AT&T’s share price appears to reflect growing investor confidence, as shifts in the competitive landscape and consistent consumer demand have supported optimism in the sector.

But even if you see that upward curve, the question remains: is the stock still attractively valued now? To answer that, let’s take a closer look at how AT&T measures up using several tried-and-true valuation frameworks. The company currently earns a value score of 5 out of 6, meaning it checks the box for being undervalued in nearly every major method analysts use. Before we reveal what those valuation strategies have uncovered, we’ll also highlight a better, more practical way to make sense of valuation, which we’ll return to at the end of this article.

AT&T delivered 41.0% returns over the last year. See how this stacks up to the rest of the Telecom industry.

The Discounted Cash Flow (DCF) model estimates a company's intrinsic value by projecting its future cash flows and discounting them back to today's dollars. For AT&T, this approach uses analyst estimates for the next five years, along with Simply Wall St's extrapolations beyond that period, providing a comprehensive outlook on the company’s long-term financial health.

AT&T's most recently reported Free Cash Flow stands at $21.57 billion. Analysts expect this figure to remain robust, with projections showing Free Cash Flow reaching $23.3 billion in 2035. Over the next ten years, cash flows are forecasted to grow steadily, based on both analyst and extrapolated estimates. This long-term view captures AT&T's ability to generate cash, which underpins its value in a DCF model.

According to this DCF analysis, AT&T’s intrinsic value is estimated at $67.35 per share. Comparing this figure to the current share price suggests the stock is trading at a 56.4% discount to its intrinsic value. This suggests that AT&T may be undervalued at present levels.

Result: UNDERVALUED

The Price-to-Earnings (PE) ratio is widely used to value profitable companies like AT&T because it directly relates the share price to earnings and provides a clear picture of how much investors are paying for each dollar of profit. When companies are steadily profitable, the PE ratio offers an efficient gauge of their valuation relative to growth prospects and risk.

What is considered a “fair” PE ratio depends on many factors. Companies with higher expected earnings growth or lower risk typically warrant higher PE ratios, while slow growers or riskier firms tend to trade at lower multiples. For AT&T, the current PE ratio is 16.6x. That is just below the telecom industry average of 16.9x and significantly below the peer group average of 24.8x. This suggests the market is being somewhat cautious about AT&T compared to other options in its sector.

Simply Wall St’s proprietary “Fair Ratio” takes this a step further. Unlike industry or peer comparisons, the Fair Ratio considers AT&T’s unique earnings growth outlook, profit margins, business risks, its size, and other sector characteristics. For AT&T, the Fair Ratio is 23.5x, nearly in line with the peer average and notably higher than the current multiple. This tailored benchmark is more insightful because it reflects company-specific realities rather than broad aggregates.

Comparing AT&T’s actual PE ratio (16.6x) to its Fair Ratio (23.5x), the stock appears undervalued in the context of its fundamentals and risk profile.

Result: UNDERVALUED

Earlier we mentioned there’s an even better way to understand valuation, so let’s introduce you to Narratives. A Narrative is your own story or perspective about a company, such as AT&T, which you connect to your assumptions about its future revenue, earnings, margins, and fair value.

This approach helps you anchor your investment decision in both the company’s business story and your expectations for its financial outlook, linking what you think will happen to a fair value that’s personal to you.

Narratives are available within the Community page on Simply Wall St, where millions of investors use them to compare their view to others, track how those assumptions stack up, and see if a stock is undervalued or overvalued compared to its current price, all in a transparent and user-friendly way.

Unlike typical valuation methods, Narratives update automatically as new news, analyst forecasts, or earnings releases come in. This way, your fair value always reflects the latest information.

For example, on AT&T, one Narrative assumes a bullish outlook with a fair value up to $34.00 based on strong 5G and fiber growth. Another Narrative takes a more cautious stance with a fair value of $15.49 based on concerns about competition and legacy service declines. This approach lets you decide which story (and fair value) matches your own view best.
