NEW YORK (Reuters) -Macy's forecast annual sales below market expectation on weak demand for its apparel and shoes and said it would close 150 stores through 2026 in a new turnaround plan, sending its shares down about 2% before the bell on Tuesday. The move comes as sluggish sales has landed the upscale retailer in the crosshairs of activist shareholders and attracted potential bidders. Macy's is facing a proxy battle from Arkhouse Management after the investment firm nominated nine director candidates last week.
