Panasonic sold a majority interest in Panasonic Automotive Systems to Apollo Global Management. "Shares of Panasonic Holdings have been on a tear ever since, up more than 70% since the deal was completed." The market is explicitly rewarding Japanese conglomerates that shed non-core, capital-intensive divisions. This validates the "conglomerate discount" unwind thesis. Panasonic's willingness to partner with PE (Apollo) allows them to focus capital on core growth while retaining a stake in the upside of the spun-off unit. Long Panasonic as a primary beneficiary of the TSE's corporate governance reforms. Cyclical downturn in the global auto industry affecting the remaining stake's value.
