Filing Released Lang Actions
Informations privilégiées / Communiqué sur comptes, résultats
Report Publication Announcement Classification · 1% confidence The document is a short press release (‘Communiqué de presse’) announcing a delay in the publication date of the company’s annual financial accounts for 2025. It does not contain the actual financial report but simply informs shareholders/investors of the new timing. Under the “menu vs meal” rule, this is an announcement about the publication of a report, not the report itself, so it should be classified as a Report Publication Announcement (RPA).

Franchissement de seuil
Major Shareholding Notification Classification · 1% confidence The document is a declaration filed with the French Autorité des marchés financiers (AMF) under article L.233-7 of the French Commercial Code, reporting the crossing of shareholding thresholds (50% of capital and voting rights). It provides detailed share counts and percentages for an individual and a holding company, which matches the category for major shareholding notifications. Therefore, the filing type is Major Shareholding Notification (MRQ).

Acquisition ou cession des actions de l'émetteur / Transactions sur actions propres (version détaillée)
Share Issue/Capital Change Classification · 1% confidence The document is a corporate press release announcing the cancellation of 2,000,000 treasury shares following a share buyback offer (Offre Publique de Rachat d’Actions) and stating the resulting capital reduction. It also details the new share count, revised share capital, and notes the impact on major shareholding thresholds. This is a “capital change” announcement rather than a full financial report or earnings release. Under the defined categories, it best fits “Share Issue/Capital Change” (SHA).

Communiqués publiés en période d'offre publique d'acquisition / OPA Modalités de mise à disposition de la note d'information visée ou de la note en réponse visée
Transaction in Own Shares Classification · 1% confidence The document is a press release announcing the availability of an information memorandum and 'other information' document regarding a public share buyback offer (Offre publique de rachat d'actions) initiated by Groupe Tera. It explicitly states that the documents have been filed with the AMF and are now available to the public. Following the 'Menu vs Meal' rule, this is an announcement of the availability of regulatory documents rather than the regulatory documents themselves, making it a Report Publication Announcement (RPA).

Informations privilégiées / Autres communiqués
Transaction in Own Shares Classification · 1% confidence The document is a press release from Groupe TERA announcing a strategic shift in its operational scope following a business divestiture and the initiation of a public share buyback offer (OPRA). It includes detailed financial tables, pro-forma data, and forward-looking statements regarding the company's business plan. While it discusses financial results and capital structure, it is primarily an announcement of a corporate action (the share buyback) and a strategic update, which fits the 'Share Issue/Capital Change' (SHA) category as it pertains to the company's capital structure and share count reduction, or potentially 'Regulatory Filings' (RNS). Given the specific focus on the share buyback (OPRA) and the resulting change in capital structure, 'SHA' is the most precise classification.

Communiqués publiés en période d'offre publique d'acquisition / OPA Autres communiqués
Transaction in Own Shares Classification · 1% confidence The document is a press release announcing that an Extraordinary General Meeting (AGE) of Groupe TERA has approved a capital reduction through a share buyback program (offre publique de rachat d'actions) for the purpose of cancellation. While it involves a shareholder meeting, the core subject matter is the company's decision to repurchase its own shares to reduce capital, which falls under the specific category of 'Transaction in Own Shares'.
