Wall Street looked set to open narrowly mixed on Tuesday, amid a slew of Dow component earnings reports and ahead of major central bank meetings.
3M posted earnings that beat by one cent a share, on revenue a touch below estimates. The firm lowered its guidance for 2016 sales growth.
Caterpillar reported earnings that beat on both the top and bottom line.
DuPont posted earnings that beat on both the top and bottom line, and raised its full-year forecast. Shares were more than 1 percent higher in pre-market trade.
McDonald's fell more than 3 percent in pre-market trade after reporting a lower-than-expected rise in U.S. same-store sales. Quarterly earnings, ex-items, did beat expectations.
United Technologies raised full-year guidance and posted quarterly earnings that beat on both the top and bottom line.
Verizon reported quarterly earnings that topped expectations on revenue that missed. The telecommunications giant said a seven-week workers' strike hurt results.
