Royal-linked dynasty based in $7M mega mansion is destroyed by father and sons shocking secret dealings

A family dynasty based out of a $7million Miami mansion has been devastated after the patriarch and his son pleaded guilty to insider trading. 

Mauro Nannini, 64, and his son Federico, 26, admitted to profiting more than $1 million thanks to a scheme they conducted alongside Alejandro Thermiotis - who is the brother-in-law of Jordans Princess Iman.

Federico Nannini shared confidential information with the group that he obtained through his position as an adviser for MasTec on its planned acquisition of Infrastructure and Energy Alternatives.

Mauro Nannini and Thermiotis then used the information to buy shares at a lower price before the information became public.

The three men pleaded guilty to the scheme on Monday, with District Judge Rodolfo Ruiz describing them as products of privilege, per the Miami Herald.  Federico Nannini was sentenced to six months in prison, Mauro Nanninni to three and Thermiotis to five. 

Hundreds of Nannini relatives and supporters were in the courtroom for the sentencing.  

Judge Ruiz said Mauro Nannini, a prominent former stock broker from Venezuela, should have stopped the scheme, which he called boneheaded and careless, as the young men conducted the fraud through text messages.

Federico Nannini cried as he apologized to the court and said his dream was a career in finance.

But then I made a terrible decision that I will regret for the rest of my life. ... The day I got arrested was the lowest point of my life, he said.

The scheme began in June 2022 when Federico Nannini began working for MasTec -an engineering and construction company based in Coral Gables that provides infrastructure services for the energy, utility and communications industries.

Federico Nannini then started sharing the confidential information with his father, Mauro Nannini, and Thermiotis, a close friend. Federico and Thermiotis and Tonarely all met at one of Miamis private schools. 

Mauro Nannini bought shares in Infrastructure and Energy Alternatives the day after his son got access to the financial information about the proposed MasTec acquisition.

Thermiotis also passed along the insider information about the deal to Tonarely. 

As the MasTec acquisition progressed, Federico Nannini continued to update his father and close friend, Thermiotis, about the deal. In turn, Thermiotis continued to share the insider information with Tonarely, prosecutors said.

At one point in July 2022, when Federico Nannini became worried the acquisition would not go through, Mauro Nannini sold his IEA stock, according to the indictment.

When Federico Nannini received confidential financials that indicated the acquisition was going forward, he texted Thermiotis, who responded.

At that point, Mauro Nannini began to buy back his position in IEA stock and options, the indictment said.

When MasTec’s acquisition of IEA was reported publicly on July 25, 2022, Mauro Nannini, Thermiotis, and Tonarely all sold their shares and option contracts in IEA at a profit.

A couple days later, Federico Nannini texted Thermiotis a picture of a Rolex Daytona and wrote: You wanna hook it up for the boy. I know it’s a little over budget but this is the one.

Thermiotis replied: Haahaha yeah but give it a bit. ... Prices should come down a bit on everything.

The men were arrested in September, 2024.

Thermiotis is the King of Jordans relative. Thermiotis’ brother, Jameel, married King Abdulla’s daughter, Princess Iman, in 2022.
