These are all projections and, as such, they are based solely on the expectations of the managers regarding the future of the company and their continued access to capital to finance the company's business plan. The realization of said estimates in the future depends on the behavior of market conditions, regulations, competition, and the performance of the Colombian economy and the industry, among other factors, and are consequently subject to change without prior notice.
