AECOM vs ISS A/S: Which Stock Looks Stronger in 2026?

ISS A/S holds the cleaner structural position, with growth as the main driver and stability adding further support. AECOM still has the edge on valuation, which keeps the comparison from looking entirely one-sided. On the market side, ISS A/S is in better shape — its trend is intact while AECOM's trend has broken down. That puts structure and market broadly in agreement — ISS A/S's lead looks more confirmed than conflicted.

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, ISS.CO: STOXX 600).

The lead is spread across growth and stability, rather than sitting in one isolated gap.

Trajectory Similarity
0.81
Similar
Peer-set rank: #9
within AECOM's functional peer set

This comparison is anchored in long-term financial trajectory similarity within the selected peer universe.

This level of similarity signals a strong structural match, even though some dimensions still separate the two companies.

The clearest structural overlap shows up in investment intensity and margin consistency.

Entry today — historical context

Where ACM and ISS.CO each sit in their own 5-year price and valuation history.

Today ACM sits in the lower portion of its own 5-year history (22nd percentile), while ISS.CO sits higher in its own history (99th). Within each stock's own 5-year context, ACM is at a historically more favourable entry position than ISS.CO. This reflects entry timing, not which company is structurally stronger — peer-relative analysis is a separate question addressed above.

Earnings growth is one contributing factor within the growth lead.

What keeps the gap from being one-sided

AECOM still shows lower market-fundamental divergence, which keeps the wider picture mixed rather than completely one-sided.

What this means for the comparison

Growth is the clearest driver of the lead, with stability adding further support — though valuation still provides a real counterweight.

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.
