OG Nation, Inc. (Pink Sheets: OGNA)

December 11 - OG Nation Update: HydroPower Initial Production Phase Completed, Initial Rollout Slated for the New Year

OG Nation, Inc. (Pink Sheets: OGNA) announced that in an effort to maintain the greatest possible transparency and to facilitate communication with the market, the Company would like to update its shareholders and potential shareholders on the latest developments in its initial product rollouts. As previously announced, OG Nation is in production of its highly anticipated HydroPower line of advanced flavored waters, with distribution originally scheduled to begin prior to the end of the year. However, due to an unanticipated production issue related to the product labeling, distribution has been rescheduled for initial rollout just after the first of the year. The Company has been inundated with requests for more information about its current plans, and wanted to issue this statement in response to the tremendous level of interest.

According to a Company spokesperson, "We are understandably anxious to see the tangible results of our concerted efforts over this last year come to fruition in the form of our product on retail shelves, but the last thing that we want to do at this point is to allow our eagerness to overcome our better judgment. Because of a minor issue with the labeling, as well as the impending holidays, we felt that it was prudent to take the additional time to ensure that we give HydroPower every opportunity to succeed. We have spent countless hours on product testing, test marketing, and design, and it would be tragic to feel that we had undermined all of our efforts simply to conform to a self-imposed deadline. As it stands right now, the first phase of production is complete, and once the labeling issue has been corrected, we will be able to hit the ground running as we approach the new year."
