Toshiba has chosen a group led by Bain Capital — which includes Apple — to buy its ailing chip business, The Wall Street Journal reports. Toshiba has outlined a plan to stay involved in the business after the estimated $18 billion sale, signing a “nonbinding document saying they intended to reach a deal by September 30.” The deal still has to clear a review from antitrust regulators and objections from Toshiba partner Western Digital, which claims it has the right to veto the sale. Toshiba disputes that claim, and the issue is headed for international arbitration. If the deal ends up going through, Apple would likely find it much easier to secure its chip supply as demand continues to increase. Some Apple products have seen slight price increases in the past few weeks, leading to speculation that rising memory costs could be to blame, so locking down a reliable supply would leave one less thing for Apple to worry about as it continues pushing the limits of its internal components and trying to bring more of its production in-house.
