NN Group stock (ISIN NL0010773842) closed at EUR 80.96 on Euronext Amsterdam on September 21, 2026, gaining 0.90 percent from the previous close. The insurer's market capitalization stood at EUR 21.29 billion, giving the latest move a material company-specific scale.

Stock reaches EUR 80.96

The September 21, 2026 session covered EUR 80.30 to EUR 81.28, with 412,404 shares traded. NN Group stock therefore finished EUR 0.32 below the session high, while the closing level was EUR 22.16 above the price recorded on September 22, 2025, a 37.69 percent year-on-year increase.

The preceding completed session was weaker: on September 18, 2026, the shares closed at EUR 80.24 after a decline of about 1.1 percent, according to Ad-hoc News. The contrast between EUR 80.24 and EUR 80.96 shows that the latest daily gain followed a short pullback rather than a one-direction move.

Valuation scale shapes the move

At EUR 21.29 billion, NN Group's market capitalization places the 0.90 percent daily increase in the context of a large listed insurer rather than a thinly traded small-cap. The September 21 volume of 412,404 shares also provides a dated measure of participation in the move.

The one-year comparison is the stronger signal in the available market data: EUR 80.96 on September 21, 2026, versus EUR 58.80 on September 22, 2025, represents an increase of EUR 22.16, or 37.69 percent. That comparison is materially larger than the single-session gain and remains the clearest numerical measure of the stock's recent performance.

Amsterdam close remains the reference

NN Group stock's reference quotation is the Euronext Amsterdam price in euros. The latest completed closing price was EUR 80.96 on September 21, 2026, with a daily change of 0.90 percent and market capitalization of EUR 21.29 billion.
