Amrize Ltd

Solid Q3 operating performance despite weather (good): Revenue rose 2.2% YoY to $3.7B (per prepared remarks), driven by strong pricing plus M&A contributions. Net income increased 3.3% to $558M, adjusted EBITDA rose to $1.1B, and diluted EPS increased 4.1% to $1.02. Building Materials margins expanded +30 bps—notably helped by cement/aggregates pricing, energy/fuel/freight surcharges, and progress on ASPIRE savings.

Segment trends were mixed—weather + residential softness weighed (bad): - Building Materials: Revenue +1.8% YoY to $2.8B; cement pricing +1.8% YoY (improving vs prior +0.2% decline last quarter); aggregates pricing +6.9% YoY (accelerating vs +4% in Q2). But cement volumes -4.2% YoY and aggregates volumes -0.2% YoY, attributed largely to weather headwinds in key regions; cost inflation (freight/diesel/raw materials) partially offset by ASPIRE and surcharges. Adjusted EBITDA +$938M (+2.7% YoY). - Building Envelope: Revenue +3.6% YoY to $929M, with commercial roofing stronger (data centers/warehousing/education; system-focused sales). Residential remained pressured due to slower existing home sales, lack of significant storms, and lower re-roofing, leading to adjusted EBITDA -14.6% YoY (higher freight/raw materials and pricing lag vs oil-driven cost inflation).

Price/cost trajectory: Building Materials positive into Q4; Envelope pain likely extends into 2027 (key risk/negative + outlook): - Company expects Building Materials to remain price-over-cost positive in Q4 (cement pricing expected positive in Q4, and flat to low single-digit for full year; aggregates mid-single-digit growth for full year). - For Building Envelope, they expect sequential improvement in Q4 (better price-over-cost spread vs Q3), but magnitude of YoY inflation pushes price-over-cost positivity expectations into 2027. Management explicitly noted petrochemical-based raw material inflation (beyond just freight/diesel) and the residential market’s double-hit (weak storms + destocking).
