PT Financier’s Shell Company Network Exposed

Cancun — An investigation by Mexicans Against Corruption and Impunity (MCCI) has revealed that César Adrián Gamboa Montejo, the official responsible for the finances of the Labor Party (PT) in Quintana Roo, created an extensive network of shell companies. The Tax Administration Service (SAT) confirmed these companies as fraudulent invoicing schemes used to receive millions of pesos from contractors associated with the Fourth Transformation (4T) government, with the funds allegedly intended for use in political campaigns.

A review of records at the Public Registry of Commerce revealed that the PT fundraiser has participated in 20 companies in Quintana Roo. Twelve of these companies have been included on the SAT's official list of "shell companies," meaning they have simulated operations for the purposes of tax evasion, money laundering, or diversion of public funds.

The companies in which Gamboa Montejo participates, who was involved in financing Morena's state and federal campaigns, are part of a larger network of at least 40 "front" companies that share addresses, representatives, and partners.

Following the Money Trail

The thread was set in motion by an investigation from the Superior Audit Office of the Federation (ASF), which followed the money trail of two contracts. Through an analysis of account statements provided by the National Banking and Securities Commission (CNBV), it discovered that Grupo Tecno, which received contracts worth 4 billion pesos during the López Obrador administration, had funneled public funds from the Ministry of Health to six shell companies listed by the SAT.

MCCI confirmed that, in addition to Grupo Tecno, these shell companies have received money from other taxpayers, mainly tourism service providers in Quintana Roo.

In 2020, just six of the largest invoicing companies in this network issued tax receipts for 252 million pesos. That money was then dispersed to Ochi Consulting and Tekteka, two other companies that issue invoices for simulated operations (EFOS), and SF Consulting & Services, a company established with identities stolen from residents of popular neighborhoods in Nuevo León.

The banking and tax tracking by the ASF identified that nine companies listed by the SAT as EFOS had invoiced Grupo Tecno in 2020 for an amount exceeding 55 million pesos.

Among the shell companies identified by the ASF were Adana Consulting, Lonnings Services, Palgafond, Parolla Consulting, Podavanie, Innovación Integral del Caribe III, and Servicios en Innovación Empresarial del Caribe. In these companies, César Adrián Gamboa, the PT's financial operator in Quintana Roo, had served as attorney and representative.

MCCI also identified that Grupo Tecno transferred an additional 10.6 million pesos to Shuttle Boost and Lex Turism, two other companies in which the PT's financial officer was listed.

Contradictions and Falsehoods from the PT Financier

Gamboa Montejo has served as the PT's financial operator since 2022, when he supported the campaign of the current Quintana Roo governor, Mara Lezama. He was only ratified in the same position before the National Electoral Institute (INE) on November 3, 2025, according to documents obtained by MCCI.

In a brief telephone interview in 2024—when MCCI began this investigation—César Adrián Gamboa Montejo said he is a member of the PT and acknowledged that he was responsible for the finances of the PT in Quintana Roo. However, he assured that his role as financial officer concluded in 2022, the year Mara Lezama won the governorship representing the Morena-PT-Green Party coalition.

MCCI confirmed that he lied, because documents from the INE dated June, September, and November 2025 show that he still holds the position of Finance Manager of the PT. Also, in March 2024, he was photographed in preparations for Claudia Sheinbaum's campaign in Quintana Roo.

Notary and Front Men Implicated

When interviewed, Gamboa Montejo also distanced himself from the 20 companies in which he appears as attorney, administrator, or representative, though he acknowledged collaborating between 2014 and 2022 with notary Jorge Alberto Galván García, who established most of the companies in the phantom network.

Gamboa Montejo appears protected by using front men to distance himself from direct involvement in the shell companies. One such case is Anastacio Zum Uc, who in official documents appears as a prosperous businessman with participation in at least 20 commercial companies. However, “Tachito,” as his friends identify him, is actually an indigenous Mayan man originally from Tepakán, Yucatán, who works as an assistant in a tax office in Quintana Roo. The multi-million dollar businesses in which he supposedly participates are not reflected in his standard of living, as he and his family reside in a small house on the outskirts of Cancun.

In three other "phantom" companies, legal power was granted to a person named José Luis Barriga Cortés, who has stated on social networks that he works as a private driver in a company in Naucalpan, State of Mexico.

Most of these front men are linked by one figure: Jorge Alberto Galván García, public notary number 74, based in Cancún. He has been accused of creating multiple shell company schemes. The facade of that notary's office was shot at in 2018, when the notary was accused of simultaneously heading a payroll or outsourcing intermediary company called Empowerment while litigating in favor of other companies in the same line of business, violating the Notary Law.

Yordi Giovanni Tuz Poot and his brother José Alfredo worked as drivers for an outsourcing company with notary Galván García and, although they did not know it, both appear in companies of this notary's network as attorneys and/or partners.

The home of Yinny Marisol Pérez Gómez, another representative of Innovación Integral del Caribe III, was visited by reporters. Her father explained that she has no involvement in any company and asked the reporters to leave.

The alleged shareholders of this phantom network are secretaries, employees, and drivers from legal and accounting firms in Quintana Roo, although there are also people from marginalized areas of Nuevo León whose identities were stolen, according to testimonies gathered by MCCI.

4T Contractors Funneled Resources

One of the contractors of the government of Andrés Manuel López Obrador that transferred the most money to the invoicing companies of the PT financier is Grupo Tecno. In 2020, it obtained a contract from the Ministry of Foreign Affairs for the issuance of passports. That same year, Juan Carlos Torres Guzmán's company began transferring 65 million 800 thousand pesos to eight shell companies in Gamboa Montejo's network, which covered the operations with more than 250 tax receipts.

In 2020, when those transfers were made, Grupo Tecno also had current contracts with the Ministry of Health, with Telecommunications of Mexico (now Financiera del Bienestar), and with the National Electoral Institute, from whom it received payments of 112 million pesos that year.

In that year and the next, the company received ten more contracts totaling 374 million pesos with Cenace, Bancomext, ISSSTE, Pemex, Nafin, DIF, Finabien, and the INE. In total, it received contracts for more than 4 billion pesos during the López Obrador administration.
