Averi-Mantengu Reverse Merger Bid Tests JSE as Gateway for Pan-African Infrastructure Capital
A proposed reverse merger between Averi Finance and JSE-listed Mantengu would create a combined R3 billion pan-African investment platform spanning energy, mining, and cross-border infrastructure, raising substantive questions about where African infrastructure capital should be listed, regulated, and governed.
The Transaction Structure and Its Regulatory Triggers
Averi Finance, a Mauritian-regulated, Dubai-headquartered investment holding company, and Mantengu, a Johannesburg Stock Exchange-listed mining investment group, announced on 14 May 2025 that they had entered “early stage” negotiations over a reverse merger. The deal, if completed, would consolidate Averi’s asset-backed portfolio into an enlarged Mantengu group.
Under the proposed terms, Averi would receive 650 million newly issued Mantengu shares in exchange for its portfolio, giving Averi a 66.7% controlling interest in the enlarged listed entity. Existing Mantengu shareholders, holding 325 million ordinary shares, would retain a 33.3% stake.
Averi carries an implied equity value of R2 billion in the transaction; Mantengu is valued at R1 billion, producing a combined pro-forma enterprise value of approximately R3 billion. Both companies cautioned that no certainty exists at this stage that a transaction will be concluded.
The JSE has classified the proposed deal as both a Category 1 transaction and a Reverse Takeover under its listings requirements, triggering a change of control under South Africa’s Companies Act. Mantengu must issue a shareholder circular and convene a general meeting for approval. A waiver of the mandatory offer obligation under the Companies Regulations is anticipated as a condition of closing.
Averi’s Infrastructure Logic: Energy Corridors as Strategic Assets
Averi Finance positions itself as an asset-backed platform with licensed and contracted positions across power transmission, energy trading, utility-scale renewables, oil and gas, and digital infrastructure in Southern Africa. The company reports an advisory and transaction record spanning more than 100 transactions representing over US$15 billion in cumulative value.
Averi CEO Gaspar Lino described the portfolio’s core thesis as vertical infrastructure integration: direct ownership of oil and gas assets, utility-scale renewable generation capacity, and cross-border transmission lines designed to connect power-surplus regions to power-deficit and mining-intensive zones across sub-Saharan Africa.
“Our diversified but deeply complementary infrastructure and investment portfolio provides a significant competitive edge, unlocking substantial opportunities in critical minerals, mining, and the new energy economy,” said Lino.
The company has invested across ten African markets over the past decade, including South Africa, Angola, and the Democratic Republic of the Congo. Its decision to seek a public listing on the continent, rather than in Dubai or a European financial centre, reflects a deliberate repositioning toward African institutional capital markets.
Mantengu’s Structural Constraint: The Mid-Tier Capital Access Problem
Mantengu CEO Magen Naidoo identified a well-documented structural weakness in African mining finance: mid-tier JSE-listed miners consistently face constrained access to growth capital, limiting their ability to scale operations or hedge against commodity cycle volatility.
“Beyond the balance sheet benefits, the transaction unlocks industrial synergies: diversified revenue streams, improved energy security and reliability, and lower, more stable energy input costs for our mining operations,” said Naidoo.
The vertical integration of Averi’s energy assets with Mantengu’s mining operations addresses a specific cost structure problem. African mining operations, particularly in Southern and Central Africa, carry disproportionate exposure to energy input costs driven by unreliable grid supply and dependence on expensive independent power producers. Internalising energy generation and transmission capacity within the same corporate group restructures that cost exposure materially.
Naidoo indicated that upon completion, the parties intend to rename the enlarged entity and reconfigure its board and management structure. The combined group is expected to seek elevation to the JSE Main Board from its current listing tier.
Mantengu’s share price closed 2.63% higher at 39 South African cents on 14 May 2025, though this remains significantly below its 59-cent level recorded a year earlier, reflecting the capital market pressure that makes the transaction strategically attractive for existing shareholders.
Governance Architecture: Mauritius Regulation, JSE Listing, African Assets
The proposed structure surfaces a governance question with direct relevance to African capital market development: Averi is regulated in Mauritius, headquartered in Dubai, holds assets across ten African jurisdictions, and is now seeking its public market anchor on the JSE. This multi-jurisdictional architecture is common among pan-African investment platforms but raises legitimate questions about where regulatory accountability sits relative to where economic impact is generated.
Mauritius has long served as a preferred regulatory domicile for African-focused investment vehicles, offering treaty networks, regulatory predictability, and investor protection frameworks that many continental jurisdictions have not yet replicated. However, the African Union and individual member states have increasingly scrutinised this arrangement, particularly regarding tax treaty benefits and profit repatriation flows that bypass domestic revenue authorities.
For the enlarged Mantengu group, JSE listing requirements impose substantive disclosure, governance, and shareholder protection obligations that provide an institutional floor. The JSE’s classification of the deal as a Reverse Takeover, with mandatory shareholder approval and Companies Act change-of-control provisions, demonstrates that South Africa’s capital market regulatory framework retains meaningful teeth in cross-border consolidation scenarios.
The question of whether the JSE can serve as a credible anchor exchange for genuinely pan-African infrastructure platforms, as opposed to primarily South African corporates with continental exposure, has broader implications for African capital market integration under the African Union’s Financial Integration Agenda and the continent’s broader AfCFTA framework, which envisions deeper cross-border investment flows supported by harmonised regulatory standards.
Regional Integration Implications: Capital, Energy, and Critical Minerals
The proposed platform’s sectoral focus, spanning critical minerals, cross-border energy transmission, and oil and gas, positions it directly within the strategic priorities identified by both the African Union’s Agenda 2063 and the AfCFTA’s investment protocol, which entered its operational phase in 2024.
Cross-border energy transmission infrastructure, specifically the transmission corridors connecting power-surplus hydroelectric regions in Central Africa to mining and industrial zones in Southern Africa, represents one of the most capital-intensive and institutionally complex investment categories on the continent. The Southern African Power Pool (SAPP) has long identified financing gaps in cross-border interconnection as a primary constraint on regional energy security.
A publicly listed, institutionally capitalised vehicle with direct ownership of transmission assets and contracted energy trading positions could, in principle, attract the patient infrastructure capital that development finance institutions alone have been unable to mobilise at scale. The critical test will be whether the enlarged entity’s governance structure, disclosure standards, and benefit distribution mechanisms meet the expectations of both African institutional investors and the host governments whose regulatory approvals underpin the asset base.
For West African policymakers and investors observing from Accra, Lagos, or Abidjan, the Averi-Mantengu transaction offers a structural template worth examining: vertical integration of energy and mining assets, anchored by a regulated public listing, as a mechanism for mobilising institutional capital toward the infrastructure gaps that constrain industrial development across the continent. Whether the JSE or a future pan-African exchange serves as that anchor remains an open institutional question, but the direction of travel is clear.
