Check out which companies are making headlines before the bell:
United Continental — United missed estimates by 2 cents with adjusted quarterly profit of $4.53 per share, with revenue in line. The airline's revenue per available passenger seat mile — a key industry metric — fell 5.8 percent.
3M — 3M beat estimates by 5 cents, earning $2.05 per share for the third quarter, though revenue came in below forecasts. The company also lowered the top end of its yearly earnings forecast, and said it would cut 1,500 jobs in a restructuring.
Caterpillar — The heavy equipment maker fell 3 cents shy of estimates with adjusted quarterly profit of 75 cents per share, with revenue also missing the mark. The company also lowered its full year earnings forecast due to a challenging environment in most of its markets.
Dunkin' Brands — The doughnut chain beat estimates by 1 cent with adjusted quarterly profit of 52 cents per share. Revenue also beat forecasts, although the company is calling its 1.1 percent increase in same-store sales "disappointing."
Stanley Black & Decker — The tool maker reported adjusted quarterly profit of $1.55 per share, 11 cents above estimates. Revenue also beat forecasts, and the company raised its 2015 earnings outlook despite what it calls a "challenging" near-term outlook caused by currency pressures and volatile economic conditions in a number of its markets.
Perrigo — The maker of private label drugs beat estimates by 3 cents with adjusted profit of $1.76 per share. Revenue missed forecasts, but Perrigo announced a series of actions — including new stock buybacks — which it said was designed to drive shareholder value superior to what would be gained in Mylan's bid to buy Perrigo.
Southwest Airlines — The airline reported adjusted quarterly profit of 94 cents per share, beating estimates by 2 cents, with revenue also above forecasts. Southwest's results were helped by an increase in profit margins spurred by lower fuel prices.

American Express — Amex reported adjusted earnings of $1.24 per share, 7 cents below estimates. Cautious spending by customers was a key factor, as average transaction levels fell by 3 percent.

AT&T is scheduled to report quarterly results this afternoon.
