Retail giant Costco Wholesale is raising its minimum wage for store workers to $15 an hour.

Executives at Costco announced the increase, from $14 an hour, for U.S. and Canadian workers during its quarterly investors call Thursday. Costco and other retail giants like Target and Amazon have announced wage increases and better benefits recently to lure in skilled workers.

The announcement came after the company reported higher than anticipated second quarter financial earnings. Net sales for the quarter increased 7.3 percent to $34.63 billion, earning $889 million in net income. Thus far in fiscal year 2019, Costco saw an 8.7 percent increase in net sales to $68.49 billion and a net income of $1.66 billion.

A spokesperson for Costco did not specify when the raise would go into effect or how many workers would be impacted, Business Insider reported .

According to The Wall Street Journal , this is the second wage increase at the company in less than a year. In June, Costco raised its minimum wage from $13 to $14 an hour. Richard Galanti, Costco's CFO, said during the call that the company will also increase wages for supervisors and has implemented paid parental leave for hourly workers.

Costco operates 770 stores, with 535 in the U.S. and Puerto Rico and 100 in Canada. It employs about 245,000 people.
