Sustainable Capital Ltd, a Mauritius-based investment firm, has substantially reduced its exposure to Seplat Energy PLC. According to a regulatory filing on April 3, 2026, the firm’s voting rights dropped from 10.01% to 6.18% as of March 30, 2026.
This “Sell-Off” involves the disposal of roughly 22.6 million shares, leaving Sustainable Capital with a remaining balance of 36,704,179 voting rights. The move comes at a time when Seplat’s stock has outperformed the broader market, gaining 55.86% year-to-date.
The Transaction: Strategic De-risking or Profit Taking?
The disposal was a “pure-play” equity transaction, with the firm opting to exit nearly 40% of its previous position.
| Metric | Before (Pre-March 30) | After (Post-March 30) | Change |
| Voting Rights (%) | 10.01% | 6.18% | -3.83% |
| Total Shares Held | ~59.3 Million | 36.7 Million | -22.6 Million |

The Timing: The exit occurred just as Seplat’s share price hit a multi-year high, driven by the Middle East war and the Hormuz blockade, which have rerouted global demand to West African producers.
-
The “Mauritius” Factor: As a Mauritius-based entity, Sustainable Capital likely manages institutional funds that may be rebalancing their portfolios toward other “AI-Energy” infrastructure plays or locking in gains from the recent commodity surge.
