Telephone and Data Systems stock (ISIN US8794331075) closed at USD 35.81 on the New York Stock Exchange on September 18, 2026, leaving the telecom and broadband group trading well below several valuation narratives that see more upside from its fiber and tower assets.

Mixed recent performance and valuation gap

According to MarketBeat, Telephone and Data Systems stock finished regular trading at USD 35.81 on September 18, 2026, down 0.73% from the prior close, with an extended-hours indication of USD 35.94 the same evening.

The same overview shows a 52-week trading range between USD 31.51 and USD 49.12, meaning the latest close leaves the shares roughly USD 3.30 above the 52-week low but USD 13.31 below the 52-week high, a gap that investors watching support and resistance levels will note.MarketBeat

As of this price snapshot, Telephone and Data Systems carried a market capitalization of USD 4.12 billion, underlining that any rerating toward higher valuation multiples would move a multi-billion-dollar equity value.MarketBeat

Consensus targets and narrative fair value

For investors looking at analyst expectations, MarketBeat reports a consensus price target of USD 47.50 for Telephone and Data Systems, which implies about 32.7% upside from the USD 35.81 closing price if that target were reached.

A separate narrative-focused analysis on Telephone and Data Systems from Simply Wall St highlights that the most followed valuation story pegs a fair value of USD 49.00 per share against a last close of USD 35.90, suggesting a perceived undervaluation of roughly USD 13.10 per share if the underlying fiber build-out and tower economics deliver as expected.

The same Simply Wall St piece notes that, over the most recent 30-day period, Telephone and Data Systems delivered a share-price return of 3.55%, but on a year-to-date basis the stock is down 12.55%, illustrating how a short-term recovery still sits within a weaker performance profile for 2026.Simply Wall St

Longer-term returns and investor perspective

Beyond this year, Simply Wall St points out that Telephone and Data Systems has delivered a 3-year total shareholder return of 107.61% and a 5-year total shareholder return of 116.37%, showing that the longer-term experience for holders has been substantially better than the current year-to-date decline might suggest.

That same analysis cites a current price-to-earnings multiple of around 8.8 times for Telephone and Data Systems, comparing it with a 3.5 times fair ratio in the model, a 14.5 times industry average and a 31.8 times peer group, which places the stock below broader telecom and peer valuations but above the modelled fair multiple.Simply Wall St

For investors, this mix of a multi-year positive total return, a 2026 pullback of 12.55% year-to-date and a 30-day gain of 3.55% supports a view that the stock has been volatile but rewarding over longer stretches, while near-term performance still lags the most optimistic fair-value narratives.
