Three prominent companies have announced significant leadership changes as new chief executives prepare to take the helm of their respective organizations.

Carter's has appointed Sharon Price John, the longtime chief executive of Build-A-Bear Workshop, as its new CEO effective mid-June. John brings extensive retail experience from her leadership role at the specialty toy retailer.

Occidental Petroleum announced that Chief Executive Vicki Hollub is retiring next month after a decade leading the oil and gas company. Hollub will hand over leadership responsibilities to Chief Operating Officer Richard Jackson, who will assume the CEO role.

Meanwhile, Lululemon has named longtime Nike executive Heidi O'Neill as its incoming CEO, with her start date scheduled for September. O'Neill's appointment has generated attention among investors as the athletic apparel company prepares for the leadership transition.

These executive changes reflect ongoing leadership transitions across various industries, from retail and energy to athletic apparel. The appointments come as companies navigate evolving market conditions and seek experienced leaders to guide their strategic direction.
