The Superintendence of Companies mandates the court-ordered liquidation of Bioenergy S.A.S. and Bioenergy Zona Franca S.A.S.

Bogotá, June 25, 2020. By means of Orders 2020-01-293699 for Bioenergy S.A.S. under reorganization, and 2020-01-293715 for Bioenergy Zona Franca S.A.S. under reorganization, the Superintendence of Companies, through its Delegation for Insolvency Procedures, decreed the termination of the reorganization process for each of Bioenergy S.A.S. and Bioenergy Zona Franca S.A.S, hereinafter Bioenergy, and the initiation of the court-ordered liquidation process within the framework of the Colombian corporate insolvency law (1116 of 2006).

The decision reflects the imminent illiquidity faced by Bioenergy. Given the decrease in its revenues, Bioenergy finds it impossible to fulfill its operational obligations and to structure a payment schedule that supports any possible agreement.

Bioenergy and its shareholders worked jointly to find effective means to solve the situation, which emerged due to several reasons, including indebtedness levels, operational and administrative issues typical of a growing company, as well as ethanol market conditions. However, it was not possible to obtain new sources of short term financing, and it was unsustainable for Bioenergy’s majority shareholder to continue injecting capital in order to reach financial equilibrium in the midst of the current situation affecting the oil and gas industry.

Bioenergy has complied with all labor obligations and social security contributions for its workers. In light of the court-ordered liquidation, the appointed liquidator shall use the available resources and those obtained from asset disposal to meet Bioenergy’s obligations.

The liquidation process shall be carried out according to the Colombian rules governing these bankruptcy proceedings and under the direction of the Superintendence of Companies.
