Dish said it welcomed the waiver, which will allow full due diligence with Sprint. "We remain confident that this process will confirm the superiority of our proposal," Dish's Ergen said in a statement.
Sprint added that its board of birectors had not determined that the DISH proposal in fact constituted a superior offer under the existing merger agreement, and there could be no assurance that the DISH proposal would ultimately lead to a superior offer.
"The Sprint Board of Directors has not changed its recommendation with respect to, and continues to support, the company's pending transaction with SoftBank," Sprint said in a statement.
Sprint will continue to evaluate the DISH proposal and discuss the proposal with DISH and SoftBank.
