Spirax Group (LSE:SPX) Q3 Trading Update Lifts Focus, Is The Stock Still Cheap?
The Q3 2026 sales and trading statement call on 11 November put Spirax Group (LSE:SPX) firmly in focus for investors, as the fresh operational update coincided with an already active share price.
Recent trading has reflected that focus, with the share price climbing to £76.20 after a 3.6% one-day share price return on the Q3 call, building on an 11.4% year-to-date share price gain, even as the 5-year total shareholder return is down 48.08%.

Another View: Spirax Group On Earnings Multiples
The fair value narrative presents Spirax Group as 6% undervalued at £81.11, yet the earnings multiple tells a tougher story. The shares trade on a P/E of 28.4x. That is richer than the European Machinery sector on 20.2x and above the fair ratio of 23x that the market could drift toward over time.
Against a closer peer set, Spirax Group screens a bit cheaper, with that 28.4x P/E sitting under the 31.3x peer average, which hints at some relative value. The gap to the fair ratio still implies valuation risk if sentiment cools or earnings disappoint. Is this a quality premium you are comfortable paying for, or a stretch that needs stronger proof?
