The majority of Adenuga's fortune is derived from Globacom, the second-biggest telecom in Nigeria by market share, according to the Nigerian Communications Commission website in May 2017. Globacom revenue is calculated using the average 2016 revenue-per-subscriber multiple of two peers: MTN Nigeria and Airtel Nigeria. It was updated on April 24, 2017 to account for latest peer performance.

The billionaire's wholly-owned Mike Adenuga Group owns all of Globacom, according to its website. A 2006 report by Nigeria's Economic and Financial Crimes Commission into alleged misconduct by Nigeria's then-vice president Atiku Abubakar stated that "the equity structure of Globacom was found at some point to be [split]," with Adenuga holding 51 percent, Alh G. Subair 24 percent, and Prince Babatunde Akinyera and Okechukwu Igbomor both holding 12.5 percent. It also stated that Akinyera was probably a front for Abubakar. A Nigerian Senate panel cleared Adenuga of any wrongdoing in 2007. To reflect the possibility of past partners, this analysis calculates the cost Adenuga would have paid to buy out the partners in 2006, based on Globacom's market value at the time.

Adenuga has interests in seven oil blocks in the Niger Delta through Conoil Producing. Two of the blocks, OML 59 and OML 103, are valued based on four transactions in October 2014, where Shell sold oilfield stakes for an average price of $100,000 per-daily barrel produced. That price is discounted 30 percent to account for the "bullish nature" of the transactions. The value of two oil prospecting licenses is based on the 2007 acquisition price and discounted 10 percent for security risk. A further 15 percent discount is applied as of June 2016 to all oil assets to account for depressed oil prices. Adenuga also owns a 89.3 percent stake in petroleum products company Conoil.

Bode Opeseyitan, a spokesman for Conoil and Globacom, didn't respond to repeated e-mails, text messages and phone calls request comment.


Birthdate: 4/29/1953
Family: Married, 7 children

Mike Adenuga Jr. was born to Michael Agbolade Adenuga, a school teacher, and his wife, Oyindamola on April 29, 1953 in Ibadan, a Nigerian city located 90 miles north of Lagos. He was said to be so large at birth that he was called "John the Bull," a nickname that stayed with him to adulthood. After attending grammar school, Adenuga left for the U.S. where he received an undergraduate degree at Northwestern Oklahoma State University and an MBA at Pace University in New York. To help pay his tuition, he worked as a security guard and a taxi driver.

Adenuga returned to Nigeria after graduation and took over his family's sawmill. He used it as a base to diversify into trading, starting with sawmill equipment, and expanded into fabric and beer. In 1990, the Nigerian government, then led by military ruler Ibrahim Babangida, awarded Adenuga an oil block in the Niger Delta as part of an initiative to encourage local participation in the oil industry by private companies. A year later, Adenuga's Consolidated Oil Limited, which is now called Conoil Producing, said it became the first Nigerian company to find and produce oil in commercial quantities. Conoil Producing has interests in seven oil blocks.

The billionaire submitted the winning bid in 2002 for a wireless-carrier license being auctioned off by the Nigerian Communication Commission. He founded Globacom with a $20 million non-refundable deposit and a $180 million loan from BNP Paribas. The bidding process came under scrutiny four years later, when Nigeria's Economic and Financial Crimes Commission investigated possible misconduct and fraud by Nigeria's then-vice president, Atiku Abubaker. Adenuga was arrested and questioned about his role in allegedly accepting payments from Abubaker through his bank, Equatorial Trust Bank. He denied any involvement and left Nigeria after he was released. He didn't return until President Olusegun Obasanjo's term ended in May 2007. A Nigerian senate panel cleared Adenuga of any wrongdoing later that year.

Adenuga is married and lives in a mansion on Banana Island, one of Lagos's most expensive neighborhoods. He has seven children between his current and former wife.
