AECOM vs SPIE: Which Stock Looks Stronger in 2026?

AECOM holds the cleaner structural position, with the lead spread across valuation and stability. SPIE still leads on growth and stability, which keeps the comparison from looking entirely one-sided. The market setup is currently leaning toward SPIE, which does not confirm the structural lead. That leaves a split case: the structural lead stays with AECOM, 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 (ACM: Russell 1000, SPIE.PA: STOXX 600).

Most of the lead runs through valuation, while profitability helps make the separation broader. AECOM leads by 16 points on the overall comparison score.

Today ACM sits in the lower portion of its own 5-year history (22nd percentile), while SPIE.PA sits higher in its own history (94th). Within each stock's own 5-year context, ACM is at a historically more favourable entry position than SPIE.PA. This reflects entry timing, not which company is structurally stronger — peer-relative analysis is a separate question addressed above.

What keeps the gap from being one-sided

Stability still leans toward SPIE SA, so the lead is real without reading as one-way.

What this means for the comparison

The valuation lead is clear, but pricing and stability still pull in the other direction — the result holds, but not without friction.

How AssetNext Peer Scores Work

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.
