What did Atlas Arteria report?
- The French government's draft 2027 Budget Bill seeks to increase the Long-distance Transport Infrastructure Tax (TEILD), potentially up to 12.2%.
- The TEILD cost Atlas Arteria €126.7 million in FY25, with proceeds expected to more than double sector-wide.
- The Temporary Supplemental Tax (TST), previously expected to end in 2026, is now earmarked for extension but at a reduced take.
- Atlas Arteria's APRR and AREA entities are subject to the TEILD, while ADELAC and A79 are not currently affected.
- Legal recourse avenues are being pursued by APRR regarding the TEILD changes.
What else do investors need to know?
The draft French Budget Bill will be debated over coming months, with the final tax rates or rules subject to change before passing into law. Investors should note that the higher TEILD could more than double the sector's collective tax outlay from €600 million to €1.4 billion, directly affecting Atlas Arteria's French assets.
Meanwhile, the Temporary Supplemental Tax (TST) – initially planned as a short-lived measure – will likely remain, but with a smaller government target, dropping total proceeds from €7.3 billion to €5 billion. Atlas Arteria will keep investors posted as legislation progresses.
What's next for Atlas Arteria?
Atlas Arteria will closely monitor the French parliamentary debate and update the market when final legislation emerges. The company's legal initiatives regarding the TEILD signal an intent to actively manage and defend its French revenue streams.
On a broader note, Atlas Arteria continues focusing on delivering value through sustainable road operations across its French, US, and German assets, aiming to balance regulatory changes with disciplined management.
