The Securities and Exchange Commission recently accused Federico Nannini of insider training while his firm consulted for Coral Gables-based MasTec a few years ago. The investigation resulted in him, his father, and two friends facing civil and criminal charges.
According to the SEC, Nannini, 26, shared confidential information about MasTec's proposed acquisition of Infrastructure and Energy Alternative, or IEA, with his father, Mauro Nannini, on June 8, 2022.
Investigators reported Nannini, 26, also tipped Alejandro Thermiotis, a friend he met at Gulliver Prep in Pinecrest, on June 15, 2022. Records show Thermiotis then tipped Francisco Tonarely, a mutual friend from Gulliver Prep, and wrote in a text message, "Not a soul okay."
According to the indictment, Tonarely allegedly responded, "Obviously ... You told me not to."
According to the SEC, Nannini, 63, purchased 34,500 shares of IEA stock for about $310,730; Thermiotis bought over $1.6 million; and Tonarely, 25, bought 321. Investigators found Nannini, 63, later ended up selling and buying again.
