Analyst expectations also moved higher. According to MarketBeat, JPMorgan lifted its target from GBp 5,760 to GBp 8,250 and assigned an overweight rating on August 24, 2026. The higher target sits 7.1 percent above the September 25 price, although the stock's valuation remains exposed to the gap between strong earnings growth and a price near its annual high.
