Adjustment clause in case of share buybacks

Date of the event:

If a company buys back its own shares at a price significantly different from the market price, an adjustment to the exercise or conversion price of instrument sheld by investors may be triggered.

Why is such an adjustment necessary?

The goal is to protect investors against a transaction that could harm them. A share buyback at an abnormal price can be seen as an indirect way to grant an advantage to certain shareholders at the expense of all other investors.

Two possible scenarios:

1. Buyback at an excessively high price (above market price)

  • Selling shareholders:
    Those who sell their shares (often founders or executives) receive an amount higher than the actual value of their holdings.
  • Remaining or potential shareholders:
    The company's cash which belongs to all shareholders, is used to overpay some. The company's value decrease accordingly, indirectly impoverishing shareholders who did not sell. This is a transfer of value from non-selling shareholders to sellers.

2. Buyback at an excessive low price (below market price)

  • Selling shareholders:
    This scenario is rarer, but if it occurs, it can benefit a small circle of shareholders (e.g., the CEO's family) by allowing them to repurchase shares at a bargain price.
  • Remaining shareholders:
    Their stake is diluted in favor of the priviledged group without fair compensation (the price paid is unjust)

How does the adjustment work?

The clause provides a correction mechanism to restore fairness.

  • Initial situation:
       
    • A holder owns 500,000 warrants (BSA) that can be  exercised for 500,000 shares at a price of €10.
  • Triggering event:
       
    • The company buys back shares from an existing shareholder, paying €25 per share—a price well above the latest valuation.
  •  
  • Application of the adjustment clause:
       
    • The clause is activated because the buyback occurred at a price “significantly different” (in this case, higher) than the market.
    •  
    • The exercise price of the warrants must be revised downward. The calculation is often based on a weighted average price formula.
    •  
    • As a result: Instead of exercising 1 warrant for 1 share, the investor will obtain more shares. For example, the new exercise price could be adjusted to €8. Thus, for the same exercise amount of €5M, they would receive 625,000 shares (€5,000,000 / €8) instead of 500,000.

In summary, the adjustment offsets the loss in value suffered by investors by granting them a greater number of shares.

Conclusion

The adjustment clause in case of a buyback at an abnormal price is a crucial safeguard for investors. It aims to prevent majority shareholders or management from carrying out transactions that would unjustifiably transfer value, preserving fairness among all shareholders.
