NOS SGPS (ISIN PTZON0AM0006) stock closed at EUR 5.12 on Euronext Lisbon on September 10, 2026 after a daily gain of 4.47 percent, making it one of the strongest movers in Portugal’s PSI benchmark index on that session, according to Investing.com.

Stock performance in Lisbon

As of the close on September 10, 2026, NOS traded at EUR 5.12 on Euronext Lisbon, up EUR 0.22 from the prior session and delivering that 4.47 percent daily increase, per market data reported by Investing.com.

A same-week overview of large Portuguese stocks shows NOS with a last price of EUR 5.19, a seven day return of minus 0.8 percent and a one year return of 35.7 percent, highlighting that the shares have still delivered a strong performance over the past twelve months despite short-term fluctuations, according to Simply Wall St.

Valuation, dividends and market capitalization

In the same Simply Wall St overview dated September 10, 2026, NOS is shown with an analyst target price of EUR 4.85, implying that the latest quote around EUR 5.19 stands modestly above that average target and suggesting that the stock trades at a slight premium to the consensus valuation level identified in that screen, based on data compiled by Simply Wall St.

The same data set lists NOS with a market capitalization of EUR 2.7 billion as of September 10, 2026, placing the company firmly in the large cap bracket within the PSI index and signaling that the telecom and media group remains one of the more substantial Portuguese listings by equity value, according to Simply Wall St.

Analyst metrics and yield

Alongside valuation, the Simply Wall St screen assigns NOS a dividend yield of 6.7 percent as part of its metrics overview, indicating that on the basis of recent payout figures the stock offers a visibly above-average cash return component compared with many broader European telecom names, per the figures cited by Simply Wall St.

For investors, the combination of a roughly 35.7 percent gain over the past year, a current price near EUR 5.19 versus an analyst target of EUR 4.85 and a dividend yield above 6 percent frames NOS as a PSI constituent where total return has recently outpaced the headline target but income remains a central part of the investment case, based on the compiled data from Simply Wall St.

Closing price and recent context

At the latest referenced close, NOS stock stood at EUR 5.12 on Euronext Lisbon on September 10, 2026, with a daily change of 4.47 percent versus the prior session, while more recent data in a PSI large-cap overview show the shares near EUR 5.19 and a market capitalization of EUR 2.7 billion as of September 10, 2026.
