Background on Grupo México and Germán Larrea

Grupo México, a conglomerate led by Germán Larrea, experienced a significant drop in market capitalization after Larrea’s announcement of his intention to acquire Banamex, a Mexican bank. The company’s stock plummeted by over 15% on the Mexican Stock Exchange (BMV) following this revelation.

Grupo México’s Market Capitalization

Prior to the announcement, Grupo México’s market capitalization stood at 1.252 trillion pesos. However, after the news broke on Monday, the company lost 193.224 billion pesos in value, bringing its market capitalization down to 1.059 trillion pesos.

Stock Performance of Grupo México

On January 1, the stock of Grupo México was valued at 97.6 pesos. By the end of last week, it had risen to 160.8 pesos, marking a 64.63% increase. However, on Monday, following Larrea’s announcement, the stock closed at 136.4 pesos, reflecting a 15% decrease from its Friday closing.

Market Reaction and Analyst Opinions

The market reacted negatively to Larrea’s plan, with investors expressing dissatisfaction and selling Grupo México’s shares. Alejandra Marcos and Guillermo Quechol, analysts from Kapital Grupo Financiero, noted that the proposed deal’s value was comparable to Banamex’s implied worth, indicating market skepticism and the deal’s lack of appeal.

Banamex Acquisition Offer

Fernando Chico Pardo, the primary shareholder of Asur (an airport operator), had previously announced his intention to acquire 25% of Banamex’s assets. However, Grupo México’s offer for the same 25% stake in Banamex was deemed unattractive by analysts from Bolsa Vector, Valores Mexicanos (Valmex), and Kapital Grupo Financiero.

Debt Concerns and Integration Challenges

Analysts from Valmex highlighted that the acquisition of Banamex would increase Grupo México’s debt from 9,383 million dollars to 18,750 million dollars. While they considered the mineral company’s debt manageable with potential for reduction, they pointed out that integrating Banamex could slow down decision-making processes in Grupo México’s subsidiaries, including mining, transportation, infrastructure, and finance.
