Dow Inc. – The chemical maker earned an adjusted 86 cents per share for the second quarter, 2 cents a share above estimates. Revenue was slightly below forecasts, hurt by lower prices and volumes for some of its products.

Raytheon – The defense contractor reported second quarter profit of $2.92 per share, compared to a consensus estimate of $.264 a share. Revenue beat forecasts as well, and the company raised its full-year sales and profit forecasts as it sells more missiles and other weapons for naval ships.

Bristol-Myers Squibb – The drugmaker beat estimates by 11 cents a share, with adjusted quarterly profit of $1.18 per share.

Southwest Airlines – The airline came in 3 cents a share above estimates, with quarterly profit of $1.37 per share. Revenue was slightly below forecasts. Southwest said its results continue to be pressured by the grounding of Boeing's 737 Max jet, and it also announced it would discontinue operations at New Jersey's Newark Liberty Airport.

American Airlines — Strong travel demand boosted American's second-quarter profit, which came in slightly higher than expected. The largest U.S. airline said it took a hit from the prolonged grounding of the Boeing 737 Max.

Tesla — Tesla lost an adjusted $1.12 per share for the second quarter, significantly wider than the 40 cent loss expected by Wall Street, while revenue was also below forecast.

Ford – Ford fell 3 cents short of forecasts, with adjusted quarterly profit of 28 cents per share. The automaker's revenue came in above estimates.
