Editor’s note: This is general educational information about Nigeria’s mandatory takeover rules. It is not investment advice. It is based on the statute and regulatory documents listed at the end.
Analysis: what the line does and where it goes quiet
The Nigerian rule is stricter than the statutory text alone suggests, because the statute sets a threshold and the rules close the routes around it. The concert presumptions, the reset on every purchase between 30% and 50%, the three business day filing clock and the Commission’s power to look at intent when an exemption is claimed together make accidental or engineered avoidance difficult. The void-transaction remedy is unusually direct: the acquisition does not merely attract a fine, it does not stand.
What the framework says much less about is price. Section 142(7) establishes that shareholders shall have equal opportunities to participate in the premium payable for control, but the equal opportunity is an opportunity to receive a bid, not a right to a formula. The rules require the bid document to state the price and other terms on which shares are proposed to be acquired, without prescribing how that price relates to what the acquirer paid the seller who took it over the line. A minority shareholder reading a Nigerian mandatory offer therefore has to check the bid document against the reported terms of the trigger trade themselves, and the two are disclosed in different places.
The second quiet area is the exemption for a holder of 50% or more. It is defensible on its own terms, but it means the mandatory bid protects a dispersed register and stops protecting a concentrated one at exactly the point where a controlling shareholder is dealing with a new controlling shareholder. In a market where founder and government holdings above half are common, that is not a marginal carve-out. It is where a large share of Nigerian control transactions sit.
What the documents say
Nigerian company law treats control as something that has to be bought from everybody or from nobody. Section 142 of the Investments and Securities Act, 2025 states that a person shall not acquire shares, whether by a series of transactions or not, which carry 30% or more of the voting rights of a company, and that a person intending to acquire that much shall make a take-over bid to other shareholders. The threshold is not a disclosure trigger or a filing trigger. Crossing it converts a private purchase into a public obligation to offer the same exit to everyone else. The exchange’s own rulebook treats a takeover with the same seriousness: Rule 17.17 of the Issuers’ Rules names amalgamation, mergers, takeovers and buy-back among the events that trigger a closed period, shutting the trading window for insiders until the price sensitive information reaches the market.
What sits behind the number
The Act gives the reasoning in the same section. The Commission is to ensure that shareholders and directors of an offeree, and the market for the shares, are aware of the identity of the acquirer and offeror, have reasonable time in which to consider a take-over, and are supplied with sufficient information to assess its merits. Section 142(7) is the operative principle: shareholders of an offeree shall have equal opportunities to participate in the benefits accruing from the take-over, including in the premium payable for control.
That last clause explains the whole architecture. Control is worth more per share than a minority stake, and in the absence of a mandatory bid rule that premium is captured entirely by whichever large holders the acquirer chooses to deal with. The 30% line forces the premium to be offered to the whole register.
The Commission’s rules on mergers, take-overs and acquisitions add a second trigger the statute does not spell out. A person who, together with persons acting in concert, holds not less than 30% but not more than 50 per cent of the voting rights, and then acquires additional shares that increase that percentage, must also make a bid. Between 30% and 50% the obligation resets on every further purchase, which removes the option of creeping up to majority control one block at a time.
Acting in concert
The rules assume that a threshold expressed as a percentage will otherwise be defeated by splitting the holding, and the presumptions are wide. Persons will be presumed to be acting in concert unless the contrary is established where they are a company and its parent, subsidiaries, fellow subsidiaries and associated companies, with ownership or control of 20% or more of a company’s equity share capital treated as the test of associated company status. The list also captures a company with its directors and their close relatives and related trusts, a company with its pension schemes, a fund manager with the investment companies and unit trusts whose investments it manages on a discretionary basis, a person with their close relatives and related trusts, the close relatives of a founder with each other, a connected adviser with its client, the directors of a company facing an offer, and any persons who cooperate under a formal or informal agreement to obtain or consolidate control, or to frustrate an offer.
The burden runs the right way for enforcement. The relationship is presumed to be concert, and the parties have to prove otherwise.
What does not trigger a bid
The exemptions are specific and mostly structural. A bid is not required where the offer would go to fewer than twenty shareholders representing 60% of the members of the target, where the shares are in a private company that has not converted from a public quoted company within the preceding twelve months, or where an ailing company undertakes a private placement approved by the Commission that leaves a strategic investor above 30%. Nor is one required where the stake arises from an allotment under the company’s first initial public offer prospectus and the effect on the promoter’s voting power was disclosed in that prospectus, or on conversion of convertible securities issued with shareholder approval.
Two further exemptions turn on there already being a controller. Where shares carrying 50% or more of the outstanding voting rights are held directly or indirectly by one person, or where holders of 50% or more state in writing that they would not accept a mandatory bid, the obligation does not arise. The logic is that a bid to a register already controlled by someone else offers no real exit.
The Commission reserves the right to look through all of it. In applying any exemption it is to consider the intent of the parties and the trend of events, and may decline an exemption where it determines that the transaction has been deliberately structured to avoid making a takeover bid. A person asserting an exemption must give notice within 30 days following the acquisition and seek the exemption formally.
The sequence once the line is crossed
An application for authority to proceed with a takeover bid must be filed with the Commission within three business days of the triggering event, and section 144 makes the authority a precondition: no bid may be made unless an authority granted under that section is in effect at the date of the bid. In deciding, the Commission is to have regard to the likely effect of a successful bid on the economy of Nigeria and on federal government policy with respect to manpower and development, and to determine whether all shareholders are fairly, equitably and similarly treated. An authority remains in effect for three months from its date, or longer if extended on an application made before that period expires.
The intention to bid must be advertised in at least two national daily newspapers and on the company’s website, and announced on the floor of the exchange where the shares are listed. Where the consideration is cash or part cash, section 145 requires the offeror to ensure the funds are available. Section 146 blocks any payment for loss of office to a director in connection with a transfer of shares arising from a take-over unless shareholders have approved it by resolution, with a memorandum setting out the amount made available for inspection first.
Failure carries consequences on both sides of the transaction. Under section 143 an acquirer who fails to make the bid is liable to a penalty of not less than ten million naira, plus twenty five thousand naira for every day the violation continues, and must in addition sell down its holdings under a supervised process and relinquish control. Under the Commission’s rules an acquisition made in breach is void, and an acquirer who withdraws or cannot make a required bid must dispose of enough shares to unrelated persons within six months to fall back below 30% or 50% as applicable.
A bidder whose announced offer lapses, fails or is withdrawn is locked out for twelve months from bidding again, from acquiring further voting shares except as the Commission authorises, and from acquiring shares on more favourable terms than its lapsed offer until competing offers have been declared unconditional or have lapsed. Withdrawal of an open offer requires an announcement within 48 hours in the same newspapers, with simultaneous written notice to the target’s board, the exchanges and the target’s registered office.
