Amrize's stock tumbled over 6% on Tuesday following a downgrade by Truist, which moved the building materials company from Buy to Hold and trimmed its target price to $48 from $65. The broker cited mounting margin pressure in the commercial roofing unit and constrained near-term potential for improved cement pricing as the primary reasons for the change in view.
In a note to clients, analyst Keith Hughes highlighted that the commercial roofing segment - which makes up roughly 28% of Amrize's sales - "will take some time to pass through the very large input inflation causing price/mix erosion in 2026." Hughes pointed to disruptions in petrochemical feedstocks as a key driver: MDI, an important input for roofing products, has surged by as much as 73% amid supply interruptions tied to the Iran conflict and force majeure declarations at major producers Dow and Covestro.
On cement, which accounts for about 35% of the company's revenue, Hughes expects volumes to trend positively but warns that "the lack of pricing gains limits EBITDA improvement." He further characterized a meaningful recovery in cement pricing as "a 2027 issue at best," indicating limited near-term margin leverage from that segment.
Reflecting this outlook, Truist lowered its 2026 EBITDA estimate for Amrize to $3,199 million from $3,298 million. The revised $48 price target is based on a valuation of 10.5 times EV/EBITDA.
Beyond input-cost pressures and subdued pricing, Truist also flagged competitive dynamics in the roofing market. Hughes expects Amrize to "remain stuck in the post-spin trading range," noting new capacity entering the U.S. non-residential roofing market from Kingspan - two operating plants with plans for a third - as a longer-term headwind whose effects "will first be seen in 2027."
Finally, Hughes drew attention to notable personnel changes at Amrize since its spin from Holcim, describing the impact as "hard to quantify." The analyst's combination of raw-material-driven margin challenges, constrained cement pricing, and evolving competitive and management dynamics underpins the more cautious stance from Truist.
Summary: Truist downgraded Amrize to Hold and cut its price target to $48, citing roofing margin pressures driven by input inflation and limited near-term cement pricing upside. The firm trimmed its 2026 EBITDA estimate to $3,199 million and based its target on 10.5x EV/EBITDA. New roofing capacity from competitors and management changes add additional uncertainty.
