Eiffage Stock Hits 52-Week Low on French Concession Tax Hike Proposal

Shares in French construction and concessions firm Eiffage SA (SGEF) tumbled to a 52-week low on Tuesday following a government proposal to sharply increase taxes on motorway and airport operators. The plan has sparked investor concern over the future profitability of major infrastructure companies.

Government Details Tax Increase

The French government announced its intention to raise the TEITLD tax, which applies to long-distance transport infrastructure concessions, as part of its planned 2027 budget. The proposal would see the rate increase from the current 4.6% to as much as 12.2%.

This measure is projected to significantly boost government revenue, increasing the annual intake from approximately €600 million to an estimated €1.4 billion. According to the proposal, the additional funds will be directed toward a new “Ambition transports” fund from 2028 to finance the modernization of existing transport networks.

Market Reacts to Earnings Threat

Investors reacted swiftly to the news, sending Eiffage shares down 3.3% to €102.5. The stock hit an intraday and 52-week low of €101.05 during the session. The sell-off was sector-wide, with competitor Vinci (FOUG) also declining 2.8% to €108.

Ad

The proposed tax hike creates a direct earnings headwind for concession operators, as it directly impacts their bottom line. The formal presentation of the 2027 budget is expected on Wednesday.

Motorway Operators Particularly Exposed

The impact is expected to be especially acute for companies with significant motorway operations like Eiffage. Unlike airport operators, which often have greater flexibility to pass on higher costs to customers, motorway firms have a limited ability to increase toll prices to offset the tax burden.

The French government has explicitly stated it will monitor motorway pricing to prevent the higher tax from being passed through to drivers. This restriction limits the companies' ability to mitigate the financial impact, intensifying concerns about compressed profit margins.
