Amazon.com – Amazon is interested in possibly buying collaboration software maker Slack Technologies, according to a Bloomberg report which puts Slack's value at $9 billion or more. Separately, Instinet raised its price target on Amazon to $1,100 per share from $975 while maintaining a "buy" rating.

Alaska Air Group – The airline said a key expense measure – cost per available seat mile – will be higher than originally thought, citing one-time expenses for pilot pay hikes at its Horizon Air unit.

Bob Evans Farms – Although the food distributor's revenue was below estimates, adjusted quarterly profit of 61 cents per share easily beat consensus estimates of 42 cents. The company said it is benefiting from recent transactions that transformed it into a pure-play food distribution company.

Western Digital – The hard disk drive maker is seeking a court injunction to keep partner Toshiba from selling its chip business without Western Digital's consent. The two companies jointly operate Toshiba's primary chip plant in Japan.

Alphabet – Alphabet's Google unit struck an agreement on the nature of future tax payments in Indonesia. Early this week, the two sides had resolved a dispute on Google's 2016 tax payments.

Bank of America – The bank is laying off more workers in its operations and technology unit, in a continuing effort to cut costs.

The New York Times reports that the changes lowered monthly payments but extended the terms of the loans by decades.

Brinker International – The parent of Chili's, On The Border, and other restaurant chains was downgraded to "neutral" from "overweight" at JPMorgan Chase, which notes overall industry weakness and higher capital expenditures offsetting sales improvements. The firm said Brinker is among companies that have "exhausted their ability to engineer" further shareholder returns.

Goodyear Tire – The tire maker sees 2017 operating income to decline in the mid-single digits versus prior flat guidance, according to a Citi conference presentation.
