The approval of the Company’s asset segregation project is part of the process of creating the investment platform for road assets in Colombia and the region, which, as reported on September 2, was agreed with Macquarie Infrastructure Partners V ( “MIP V”), a private infrastructure fund focused on the Americas managed by Macquarie Asset Management (“MAM”), one of the largest infrastructure managers in the world, for the purchase and sale and contribution of its equity interests in the concessions roads in Colombia to the aforementioned platform. This process will also include the creation of a private equity fund in which Odinsa and MIP V will participate and whose professional manager will be an Odinsa subsidiary that will be set up for this purpose. The creation of the investment platform is subject to the fulfillment of precedent conditions and the obtaining in Colombia of the corresponding government authorizations. 

 • This fact represents a milestone in the country’s infrastructure and concessions sector, given that it is the first issue of bonds in pesos in the Colombian capital market to finance this type of infrastructure projects. 

• The support of Odinsa and its parent company Grupo Argos gave the transaction a seal of confidence that motivated the market’s appetite. 

• The active participation of investors, with a demand of more than $ 1.1 trillion, shows the support for the concession and its management, as well as the interest in the infrastructure sector in Colombia. 

• This operation had Grupo Bancolombia Capital as coordinator, structuring of the offer and leading placement agent, in addition to being one of the anchor investors of the issue. 

Medellín, September 6, 2021. Odinsa, Grupo Argos concessions company, reported the successful closing of the bond issue of the Túnel Aburrá Oriente Concession, carried out today, September 6, for an amount of $ 700,000 million pesos, which had a demand of more than $ 1.1 billion pesos. This fact marks a milestone in the infrastructure sector in Colombia as it is the first bond issuance directed in the local capital market, in pesos, through the Colombian Stock Exchange, to finance this type of infrastructure projects. . 

The issue, which obtained an AA + credit rating from BRC Standard & Poor’s, had Grupo Bancolombia Capital as coordinator, structuring of the offer and leading placement agent and, the accompaniment of Odinsa, as majority shareholder of the concession, matters that printed a seal of support and reassurance for investors throughout the transaction. 

“This positive response from the Colombian market demonstrates the confidence in the management developed by the concession and ratifies the interest in continuing to invest in the country and in its infrastructure, as a key sector for competitiveness and development,” said Mauricio Ossa, president of Odinsa. 

For this operation, the issue was directed to the second market with the participation of institutional investors and, with it, culminates a refinancing project that began in December 2020 in the banking market. This process of financial optimization will allow the concession to improve its debt structure by lengthening its term and reducing the financial cost of the project. 

“The mobilization of various capacities for the successful development of this operation reconfirms our commitment to promoting sustainable economic development that seeks for the well-being of all,” said Juan Carlos Mora, president of Grupo Bancolombia. “This purpose also led us to make a significant effort to participate as investors in an operation that improves the conditions of this work, which is a benchmark for the competitiveness and economic growth of the country,” he added. 

The successful issuance and placement process reflects the support for what has become one of the most relevant road corridors in Antioquia with a traffic of more than 15 million vehicles in the last 2 years. This iconic work managed to strategically interconnect the valleys of Aburrá (Medellín) and San Nicolás (Rionegro) and reduce travel times by 55% between these subregions of great economic dynamism in Antioquia through tunnels, viaducts and road interchanges that today they are benchmarks of national engineering and bring great benefits to the department. 

“Being the first concession in Colombia to make an issue with these characteristics motivates and challenges us to continue to carry out an integral management of the project, under the highest sustainability standards; promoting safe mobility; strengthening our services and implementing technologies that provide an excellent experience to users who pass through one of the most representative regions of Colombia, ”said Carlos Preciado, manager (e) of Concesión Túnel Aburrá Oriente. 

With this type of project, the Concession optimizes its current investments, generating resources that allow new investments with high social, environmental and economic value to continue generating connectivity for its users, with infrastructure and sustainable practices that contribute to the competitiveness of Antioquia and the country.
