Expected move: +26%

Biggest risk

Bear: Prolonged construction weakness or sustained input-cost inflation erodes volumes and margins, compressing the multiple toward the $540 downside scenario.

Invalidation

Break below $540 or thesis failure.

What would change my mind?

Bull: Durable infrastructure-led volume and price gains plus effective cost control drive margin expansion and multiple re‑rate toward peer highs, supporting the $820 target over 12–24 months.

Commentary

Market tone is balanced: filings highlight infrastructure opportunity but emphasize ongoing cost and execution risks. Near‑term sentiment will track earnings and guidance; medium‑term upside hinges on sustained public works demand.
