Eiffel Tower Company Shares: +109% in One Session as SMABTP Buyback Offer Boosts Value

A Stock Driven by SMABTP's €8.20 Buyback Offer

The catalyst for this surge is clearly identified. On April 2, the SMABTP group, which already holds 95.35% of Société de la Tour Eiffel's capital, announced the filing of a buyout offer for the shares it does not yet own, at a price of €8.20 per share. This price represents a premium of approximately 115% compared to the last quoted price before the announcement. The market immediately adjusted the valuation of the stock, which increased from €4 ten days ago to €7.96 this Friday morning, representing a 99% rise over the period. The RSI now reaches an extreme level of 92, indicating massive buying pressure, while the price is significantly above its 20-day (€4.16), 50-day (€4.13), and 200-day (€4.54) moving averages. Over one year, the stock now shows a performance of more than 65%, and nearly 89% over three months, with most of the movement focused on the very last few days.

Limited Residual Potential but a Readable Market Mechanism

For an investor, the situation calls for caution regarding timing. The current share price of €7.96 is closely approaching the withdrawal offer price set at €8.20, leaving only a residual gap of about 3%. This gap typically represents the liquidity premium that the market maintains as long as the offer has not concluded. The general assembly is scheduled for April 29, 2026, which could be a key milestone in the operation's timeline.

The near-zero beta of the stock (-0.03) confirms that Société de la Tour Eiffel operates largely independently of the market: geopolitical tensions in the Middle East and the prevailing volatility in the indices—the CAC 40 dropped 0.24% on April 2—have had no impact on the stock's movement, which is entirely driven by the capital operation. The principal risk now lies in a potential block or regulatory delay of the offer.
Nevertheless, SMABTP's 95.35% ownership of the capital leaves little doubt about the outcome of the operation. The issue for current shareholders boils down to deciding between selling immediately on the market at a price very close to the offered price, or waiting for the formal closure of the offer to capture the last few cents of the premium. For an external investor, the potential for gain now seems very limited compared to the risk of capital immobilization.
