What type of offer is required if a company acquires more than 30% of voting rights?

When a company acquires more than 30% of voting rights in another company, it is typically required to make an offer for all remaining shares. This obligation arises from various regulatory frameworks intended to protect minority shareholders.

The rationale is that when a shareholder reaches the 30% threshold, they have significant influence or control over the target company and can impact decisions that affect all shareholders. To ensure fairness and provide an equal opportunity for all shareholders to exit if they choose, the acquiring company must extend a full offer for all outstanding shares. This requirement aims to maintain transparency and protect the interests of those who may not wish to remain invested under new control.

The other options do not align with the regulatory expectations; for instance, an offer for some remaining shares does not guarantee that all shareholders have the chance to sell their shares at the same price, while a conditional offer based on regulatory approval or a non-binding offer would fail to provide the necessary assurance and commitment required in such circumstances.
