What happened: Long-time CEO to exit following center3 acquisition

Marisa Trisolino will step down as CEO of CMC Networks on 9 May 2025, concluding a seven-year leadership journey marked by growth and transformation. She joined the company in 2018, bringing nearly 30 years of telecoms experience to the role and steering the business through a dynamic period of development.

Why it’s important

Under Trisolino’s leadership, CMC Networks expanded its service reach to over 110 locations, covering 51 of Africa’s 54 countries and extending into 11 countries across the Middle East. Headquartered in South Africa, the company became a key player in providing secure, high-capacity connectivity to underserved and fast-developing markets.

Her tenure also helped position CMC as a strategic acquisition target for centre3, reflecting a wider telecom industry trend of consolidation and cross-regional investment. With stc Group’s resources, CMC is now poised to enhance infrastructure and service delivery across its footprint, building on the solid foundation laid during Trisolino’s leadership.
