South Africa’s ARC defeats US firm in $194 million graphite dispute

African Rainbow Capital Investments (ARC), controlled by South African billionaire Patrice Motsepe, secured a decisive legal win after a Johannesburg High Court ruling found it cannot be held liable in a $194 million dispute tied to a Tanzanian graphite project, significantly weakening claims brought by U.S.-linked Pula Group.

The court ruled that ARC was not a signatory to the confidentiality agreement central to the case, undercutting allegations that it breached non-disclosure and non-compete provisions linked to a 2019 transaction in Tanzania’s Ruangwa District.

Liability risk sharply reduced

The decision trims the immediate legal exposure facing Motsepe’s investment firm, which had been accused of backing a competing graphite venture in violation of contractual restrictions. Pula Graphite Partners and its parent company argued that ARC’s investment in Evolution Energy Minerals, operator of the Chilalo graphite project, undermined its position in a region where it holds a 50% stake.

By determining ARC had no binding obligations under the disputed agreement, the South African court effectively dismantled the foundation of Pula’s damages claim, marking a critical setback for the U.S.-linked group led by Mary Stith.

Battle shifts to Tanzania

Despite the ruling, the dispute is far from resolved. Proceedings continue before Tanzania’s High Court, where ARC is contesting jurisdiction, arguing it cannot be compelled to defend claims tied to agreements it never executed.

The firm is also seeking to anchor the dispute under South African law, citing governing clauses in the original contract, setting up a high-stakes jurisdictional clash that could shape enforcement of cross-border mining agreements on the continent.

Strategic minerals, rising legal complexity

The case underscores intensifying legal friction in Africa’s fast-growing critical minerals sector, where graphite, an essential component in electric vehicle batteries, has drawn heightened investor interest. As capital flows increase, so too do disputes over access, partnerships, and contractual boundaries.

For ARC, the ruling reinforces legal protections around investment structuring, while signaling to global investors the importance of clearly defined contractual obligations in multi-jurisdictional deals.

Portfolio strength cushions uncertainty

ARC, founded in 2015 as part of Ubuntu-Botho Investments, continues to expand its footprint across mining and financial services. The firm reported net asset value of R19.39 billion ($1.04 billion) for the six months to December 2024, up 4.1%, providing balance sheet strength as litigation risks persist.

The outcome of the Tanzanian proceedings remains pivotal. However, the South African judgment shifts momentum in ARC’s favor, reducing near-term liability while leaving a broader legal precedent still in play for cross-border resource investments.
