Check out which companies are making headlines after the bell on Wednesday:
Shares of Fitbit gained as much as 8 percent after the company posted better-than-expected quarterly results. Co-founder and CEO James Park said Fitbit saw strong sales amid unexpectedly strong demand, leading to a reduction in inventory.
Square ticked 1 percent higher after the company reported results that bested analyst expectations. The Jack Dorsey-led company posted a loss of 4 cents per share on $552 million in revenue. Wall Street had expected a loss per share of 5 cents on revenue of $536.3 million, according to Thomson Reuters consensus estimates.
Shares of AIG edged higher after the company reported earnings per share above analyst expectations. The company posted earnings per share of $1.53, easily besting a Thomson Reuters consensus estimate for about $1.20 a share.
Cheesecake Factory shares fell 7 percent after the company reported a decline in comparable restaurant sales, outweighing earnings and revenue that were roughly in-line with expectations. The company said same-restaurant sales declined 0.5 percent during the period.
In June, Cheesecake Factory updated its outlook to reflect volatility in sales trends, saying comparable restaurant sales would likely decline.
