Icop's improved exchange offer for Trevi intensifies the takeover battle, forcing investors and Webuild to reassess valuation and strategy
Executive summary: Icop improved its public exchange offer for Trevi by 24.1%, now offering 0.165 new Icop shares per Trevi share, up from the previous terms. The revised offer was announced on September 25, 2026. The battle for Trevi pits two major Italian construction groups—Icop and Webuild—against each other, with Trevi's board and market dynamics at stake. The outcome will determine control of a specialist in ground engineering and could reshape the sector's competitive balance.
Who is involved: Key actors include Icop (bidder), Webuild (competing bidder, led by Salini), Trevi's board of directors, and Trevi shareholders. The Italian financial market regulator CONSOB may also be involved in overseeing the offers.
Likely next: Webuild may respond with a revised offer or continue its existing tender, while Trevi's board will issue its formal opinion on the improved Icop offer. Shareholders will decide by the tender deadlines (Webuild's ends November 20, 2026).
On September 25, 2026, Icop raised its voluntary public exchange offer (OPS) for Trevi by 24.1%, offering 0.165 new Icop shares for each Trevi share tendered. This move comes after Trevi's board unanimously rejected the previous Icop offer as not in shareholders' interests, and follows Webuild's competing cash tender at €4.50 per share. The improved terms signal a more aggressive contest for control of Trevi, a key player in foundation engineering, with implications for shareholder value and the competitive landscape in Italian infrastructure.
What's next — scenarios
Base: Icop's improved offer gains traction (45%)
Icop's improved exchange offer attracts enough acceptances to secure control, but may still fall short of full delisting, leading to a prolonged minority squeeze-out process.
- Trevi's board issues a neutral or positive opinion on the improved offer
- Market reaction shows Icop shares stable or rising, making the exchange attractive
- Webuild does not counter with a higher cash bid before the tender deadline
Upside: Webuild raises its cash offer (35%)
Webuild increases its €4.50 per share cash offer to outbid Icop, potentially triggering a bidding war that raises the acquisition price and benefits Trevi shareholders.
- Webuild announces a revised offer with a higher price per share
- Trevi's board publicly favors Webuild's cash offer over Icop's paper
- Arbitrageurs push Trevi's share price above €4.50, signaling market expectation of a higher bid
Downside: Neither bidder secures control (20%)
If both offers fail to reach minimum acceptance thresholds, Trevi remains independent, but the uncertainty and costs could weaken its financial position and stock performance.
- Both offers expire with acceptances below required levels
- Trevi's board continues to reject both offers, and no new bidder emerges
- Regulatory or antitrust hurdles delay or block the offers
What to watch
- Trevi's board formal opinion on Icop's improved offer (expected within days)
- Webuild's potential counter-offer announcement (before October 2026)
- Webuild's OPA acceptance window: September 28 to November 20, 2026
- Icop's OPS acceptance period and any regulatory approvals from CONSOB
- Trevi's share price movement relative to €4.50 and Icop's implied value
