In connection with the shift, the company changed its name from “Long Island Iced Tea Corp.” to “Long Blockchain Corp.” and has reserved the web domain www.longblockchain.com. The company, which plans to request a trading symbol change from Nasdaq, will continue to operate Long Island Brand Beverages as a wholly-owned subsidiary and maintain the focus of that business on the ready-to-drink segment. Long Island Iced Tea also submitted a request to the Securities and Exchange Commission to withdraw its filed registration statement relating to a proposed underwritten public offering. The iced tea maker added, “The company is already in the preliminary stages of evaluating specific opportunities involving blockchain technology. The discussions are only in the preliminary stages but indicate the areas of focus for the company.”
