Exxaro CEO Nombasa Tsengwa Resigns Amid Governance Probe: What It Means for the Company

---

Exxaro Resources, one of South Africa’s leading coal mining companies, has announced the immediate resignation of its Chief Executive Officer, Dr. Nombasa Tsengwa.

The news follows her suspension in December 2024 amid an independent investigation into workplace conduct and governance practices.

Resignation Follows Suspension and Investigation

Dr. Tsengwa, who has been at the helm of Exxaro since July 2022, stepped down on February 6, 2025, marking a sudden turn of events for the company.

Her resignation follows an internal review that prompted Exxaro’s board to place her on suspension in December while launching an external probe.

The company has not provided specific details about the allegations, citing confidentiality, but stated that the resignation allows it to move forward without disruption.

In the interim, Exxaro’s long-serving Chief Financial Officer, Riaan Koppeschaar, has taken over as acting CEO while the board searches for a permanent replacement.

Potential Impacts on Exxaro and Investor Sentiment

Tsengwa’s abrupt departure could create short-term uncertainty for Exxaro, especially as the company navigates volatile global coal markets and increasing pressure to diversify into renewable energy.

Analysts warn that a lack of clarity surrounding the investigation may impact investor confidence.

“Leadership stability is crucial in a sector that faces regulatory and environmental challenges,” said mining analyst Paul Maseko. “The lack of transparency could create hesitation among institutional investors.”

However, some industry observers believe the swift response by Exxaro’s board demonstrates strong corporate governance. “If the company swiftly implements a succession plan, the long-term impact may be minimal,” noted investment strategist Zanele Nkosi.

Broader Industry Implications

Dr. Tsengwa, who also serves as president of the Minerals Council South Africa, has been a vocal advocate for transformation in the mining sector. Her resignation could have ripple effects beyond Exxaro, as the council plays a key role in shaping mining policy and industry relations.

What’s Next?

Exxaro has assured stakeholders that operations remain unaffected and that the leadership transition is being carefully managed. Meanwhile, investors and analysts will be closely watching Exxaro’s next moves, including the appointment of a new CEO and any further developments from the governance probe.

For now, the resignation raises more questions than answers, but Exxaro’s handling of the situation will be critical in shaping its reputation and market standing in the months ahead.
