Spirax holds the cleaner structural position, with the lead spread across growth and profitability. Advanced Drainage Systems still has the edge on valuation, which keeps the comparison from looking entirely one-sided. In the market, Advanced Drainage Systems carries the stronger setup — intact trend against Spirax's broken trend. That leaves a split case: the structural lead stays with Spirax, but the market is not currently confirming it.
The comparison is based on similar long-term financial trajectories, not sector labels. Peer scores are normalised within each company's primary universe (SPX.L: STOXX 600, WMS: Russell 1000).
The result is anchored in growth, but profitability also reinforces the same direction. The overall score gap is 15 points in favour of Spirax Group plc.
This comparison is anchored in long-term financial trajectory similarity within the selected peer universe.
The pair sits on a clearly comparable long-term path, though it is not a near-twin match.
The strongest overlap appears in margin trend and revenue growth trajectory.
Scores reflect position relative to comparable companies with similar long-term financial trajectories.
The largest gaps do not all point in the same direction.
Left means cheaper relative valuation. Higher means stronger structure.
Structure clearly favours Spirax Group plc, even though current pricing leans the other way.
Valuation position uses peer-relative PE percentile (idx_pct_pe) where available.
Earnings growth is one contributing factor within the growth lead.

Rule-based, descriptive analysis only. Derived from peer percentile dimensions. Not investment advice. Peer groups are determined algorithmically based on structural similarity — not by sector classification alone.
AssetNext scores reflect each company's structural position within its functional peer group — not a ranking against all stocks simultaneously. Peers are identified by similarity across eight financial dimensions, including revenue growth trajectory, margin structure, capital intensity, and earnings stability. A score of 75 means the company ranks in the top quartile within its own peer group, not the entire market.
Four dimension scores drive the overall peer score: Growth (revenue trajectory and expansion dynamics), Quality (margin structure and capital efficiency), Valuation (peer-relative pricing on standard multiples), and Stability (earnings consistency and financial predictability). Each dimension is scored 0–100 relative to the peer group, then combined into an overall peer score using equal weighting.
Because scores are peer-relative, the same company can have slightly different scores in different index universes. On comparison pages, both companies are shown within their shared peer universe wherever possible — so the scores are directly comparable. The peer basis is stated on each score card.
Scores are recalculated periodically as underlying financial data is updated. All analysis is descriptive and rule-based — AssetNext describes structural realities and never issues buy, sell or hold recommendations.
