Taukobong, a telecommunications industry veteran, will become CEO-designate on 1 October.
“Serame is a seasoned executive, with deep experience in the ICT sector in South African and the continent. His appointment ensures continuity of our value-unlock strategy,” said Telkom chairman Sello Moloko in a statement.
“Having worked under Maseko’s leadership for three years, I know I will be taking over a solid business with a capable and committed team,” Taukobong said in the statement.
“The team and I are conscious of the challenges that lie ahead and are committed to attracting and retaining the best people, winning in the marketplace, and delivering value for shareholders,” he added.
Taukobong joined Telkom in June 2018 and has extensive experience in telecoms, having spent about 10 years at rival MTN Group, where he held several senior roles which included chief operating officer and later CEO of MTN Ghana.
As CEO of the Telkom consumer business, the mobile business customer base grew three-fold to 15 million and its revenue almost doubled to R20-billion (US$1.4 billion) within a three-year period, Telkom said.
The unbundling exercise was started by Maseko, who has been credited for successfully turning the operator around from a business-facing declining fixed-line voice revenue to a digitally-led one fit to compete with the top two players, MTN and Vodacom.
The share price has more than tripled on his watch as he set about restructuring and streamlining the organization to better compete in a liberalized telecoms market.
In a statement, Maseko said: “I feel now is the right time for me to step aside and make way for a new leader who will take Telkom to even greater heights. I am most thankful to my colleagues across our country, for trusting me to lead Telkom, and for supporting me throughout this journey of transition.”
