United States of America v. Tomás Niembro Concha
Date: 03-21-2026
Case Number: 1:26-cr-20035
Judge: Kathleen M. Williams
Court: United States District Court for the Southern District of Florida (Miami-Dade County)
Plaintiff's Attorney: United States District Attorney’s Office in Miami
Defendant's Attorney: Juan Michelen, Mike Nadler,
Description:
Miami, Florida criminal defense lawyers represented the Defendant charged with conspiracy to violate the International Emergency Powers Act and Wire Fraud.
Tomás Niembro Concha, 64, of Miami, Florida, conspired with others to siphon money from Nodus Bank, ultimately leading to the bank’s failure in 2023. Niembro and his co-conspirators concealed from other Nodus Bank board members and executives and the bank’s regulator that certain investments and loans were for the benefit of Niembro and Board Chairman Juan Ramirez, in violation of Puerto Rican law. From 2017 to 2023, Niembro, Ramirez and others caused Nodus Bank to invest $11 million in a Miami-based lender so those funds could be loaned to Niembro and Ramirez for their own benefit. Niembro and his co-conspirators knew that these transactions were illegal and concealed their conduct through the sham investments.
Between January 2018 and September 2021, Niembro and Ramirez also fraudulently induced Nodus Bank’s board and comptroller to agree to buy at least 47 promissory notes totaling approximately $25.3 million from Nodus Finance, a Miami-based company that Niembro and Ramirez jointly owned, so they could use the proceeds of the transactions for themselves.
In early March 2023, Nodus’s regulator, the Office of the Commissioner of Financial Institutions of Puerto Rico (OCIF), notified the bank it would be placed into liquidation. Niembro and Ramirez fraudulently caused Nodus Bank to accept a loan portfolio from Nodus Finance to pay down the debt from the 47 promissory notes.
Moreover, between 2021 and 2023, Niembro conspired with others to conduct prohibited financial transactions with an individual designated as a Specially Designated National (SDN) by the U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC) for providing material support to Venezuela’s state-owned oil company, Petróleos de Venezuela, S.A. (PDVSA). To satisfy an outstanding loan of approximately $2.5 million that the SDN’s company had with Nodus Bank prior to the imposition of sanctions, Niembro and the SDN devised a scheme to cause Nodus Bank to foreclose on the SDN’s home in Southampton, NY — for which they obtained OFAC authorization — but separately reached a “private” agreement to induce Nodus Bank to sell the property back to the SDN for $4 million through a front company — a transaction that was strictly prohibited by U.S. sanctions and not otherwise licensed by OFAC.
Niembro pleaded guilty to a two-count Information charging conspiracy to commit wire fraud and conspiracy to violate the International Emergency Economic Powers Act (IEEPA). Each charge carries a maximum penalty of 20 years in prison. Niembro’s sentencing has been scheduled for June 8. As part of his plea agreement, Niembro agreed to forfeit at least $16.9 million, which represents the value of the proceeds he derived from the wire fraud conspiracy. A federal judge will determine any sentence after considering the U.S. Sentencing Guidelines and other statutory factors.
IRS Criminal Investigation (IRS-CI) investigated the case with support from OCIF and the Treasury Executive Office for Asset Forfeiture (TEOAF).
Trial Attorneys Javier Urbina and Samir Paul of the Criminal Division’s Money Laundering, Narcotics and Forfeiture Section (MNF) and Assistant U.S. Attorney Felipe Plechac-Diaz for the Southern District of Florida are prosecuting the case.
