How Did Dermot Desmond Get His Money?

Desmond’s path to billionaire status began in the 1970s at Citibank, where he cut his teeth in corporate finance (Wikipedia). He later worked at the Investment Bank of Ireland and PricewaterhouseCoopers, building expertise in financial services. In 1981 he founded NCB Stockbrokers, which he sold in 1994 for $39 million (CB Insights).

After that sale, he launched International Investment & Underwriting, a private investment vehicle. Through it, he has taken stakes in companies such as Datalex, Mountain Province Diamonds, Barchester Healthcare, and Celtic Plc (CB Insights). His early move into tech and finance during the 1990s positioned him for significant returns.

What companies does he own?

Desmond does not own a single flagship company. Instead, his wealth is spread across a network of private and public holdings. His most notable asset is his 34% stake in Celtic FC, which The Times (Irish rich list) valued at €43 million in 2018. He also has a significant holding in Rietumu Bank, a Latvian bank where he sat on the management board (Herald Scotland). Other known investments include Datalex (airline software), Mountain Province Diamonds, and Barchester Healthcare (CB Insights).

His private jet company, Execujet, was at the centre of a tax haven controversy when the Paradise Papers revealed it used an offshore structure while he owned it (BBC News).

What is his net worth?

Desmond’s net worth is estimated at €2.04 billion by the Irish Independent (Irish daily newspaper). The Sunday Times Irish Rich List 2018 put his fortune at €2.057 billion, ranking him fifth in the country. His wealth is tied to the performance of his portfolio, which includes both publicly traded and private holdings.

The pattern: Desmond’s wealth is a reflection of his ability to identify high-growth sectors early — finance in the 1980s, tech in the 1990s, and football as a long-term asset.

Desmond controls a portfolio of companies through his private investment firm, International Investment & Underwriting. The most prominent holdings are listed below, with their primary sectors.

Desmond also had a previous stake in Manchester United before becoming Celtic’s largest shareholder (BBC News).

Does he own a private jet firm?

Yes — Desmond owned Execujet, a private jet charter company. According to the Paradise Papers leak, Execujet used an offshore tax haven structure while under his ownership. Emails suggested the company may have avoided up to $1.3 million in Swiss taxes over three years (BBC News).

What is his stake in Celtic?

Desmond is the largest individual shareholder of Celtic Football Club, holding 34% of the club’s shares (BBC News). The Sunday Times valued his stake at €43 million in 2018. He has been a major influence on the club’s board and strategy.

The pattern: Desmond’s deep involvement in Celtic ties his personal brand to the club’s performance, both on and off the pitch.

Is Celtic richer than Rangers?

Celtic’s financial status relative to Rangers has fluctuated. In 2023, Celtic’s revenue was reported at £119 million, compared to Rangers’ £86 million (BBC Sport). However, precise comparisons depend on the accounting period and transfer activity. What is clear is that Desmond’s ownership provides Celtic with a stable financial anchor that Rangers lacks.
