A health-care consulting company plans to add 300 jobs in Charlotte over the next five years, state officials announced today.

Premier Inc. already employs about 750 people in Charlotte out of its total work force of 1,100. State officials promised the company up to $4,089,000 in incentives if it creates the new jobs and keeps all the existing ones.

The company will move its headquarters to Charlotte from San Diego as part of the expansion. The new jobs will pay average annual salaries of at least $62,460.

Premier helps hospitals reduce costs, improve care and negotiate the best prices for supplies and services. In March, the company named as its new CEO Susan DeVore, who lives in Charlotte.
