Apple will report its quarterly earnings on July 22nd, but the company just announced a bit of a board shake-up ahead of that — Bill Campbell, the companys longest-tenured board member, is retiring after 17 years of service. Hell be replaced by Sue L. Wagner, a co-founder and director at investment management firm BlackRock. Sue is a pioneer in the financial industry and we are excited to welcome her to Apples board of directors, said CEO Tim Cook in a press release. We believe her strong experience, especially in MA [mergers and acquisitions] and building a global business across both developed and emerging markets, will be extremely valuable as Apple continues to grow around the world. With Wagners appointment, two of the eight members of Apples board are women. Campbell will be retiring after working with Apple since 1983, when he joined the company as VP of marketing.
