Check out which companies are making headlines before the bell:
Ford Motor — The automaker missed estimates by eight cents a share, with adjusted second quarter profit of 52 cents per share. Revenue beat forecasts. Higher incentive costs helped lead to lower-than-expected profit margins, impacting the bottom line.
Dow Chemical — The chemical maker reported adjusted quarterly profit of 95 cents per share, beating estimates by 10 cents a share. Revenue also came in above forecasts, and Dow's bottom line was helped by a jump in profit margins that was spurred by cost cuts.
Colgate-Palmolive — The consumer products maker beat estimates by a penny a share, with adjusted quarterly profit of 70 cents per share. Revenue was very slightly shy of Street estimates. The company said it is pleased with its organic sales growth and overall performance, especially in light of challenging macroeconomic conditions.
Raytheon — The defense contractor's quarterly profit of $2.38 per share was well above estimates of $1.74 a share. Revenue topped estimates, as well. The company also raised its full-year forecast, the latest of the government contractors to forecast an improved outlook.

Hershey — The chocolate maker came in seven cents a share above estimates, with quarterly profit of 85 cents per share. Revenue beat forecasts, as well. The quarter also featured Hershey's first quarterly sales rise in a year.
Harley-Davidson — The motorcycle maker earned $1.55 per share for its latest quarter, beating estimates by two cents a share. Revenue was very slightly above estimates. Harley also lowered its full-year shipment forecast, as sales slowed in the key U.S. market.
Facebook — The social media giant beat estimates by 15 cents a share, with adjusted quarterly profit of 82 cents per share. Revenue also beat forecasts. Facebook also reported more than 1.7 billion monthly active users and its shares are poised to hit an all-time high.
Whole Foods — Whole Foods matched estimates with profit of 37 cents per share, with revenue slightly below analysts' forecasts. The grocery chain saw comparable-store sales drop 2.6 percent, more than expected, and is on track for its first yearly drop in same-store sales since 2009.
Alere — Alere received a Justice Department subpoena seeking Medicare and Medicaid billing records over the past six years. The stock initially got hit hard in after-market trading when word of the subpoena got out, but recovered strongly after the diagnostic testing company issued a statement and said it was fully cooperating and that it did not believe matters related to the subpoena were material.
Amgen — Amgen reported adjusted quarterly profit of $2.84 per share, ten cents a share above estimates. Revenue came in above forecasts, as well. The biotech company also raised its full-year outlook on stronger sales of rheumatoid arthritis drug Enbrel and other medicines.

Groupon — Groupon posted a quarterly loss of one cent per share, smaller than the two cent loss expected by Wall Street. The daily deals company also saw revenue beat forecasts, and it increased its 2016 revenue and earnings forecasts as it adds new customers.
Cheesecake Factory — Cheesecake Factory reported quarterly profit of 78 cents per share, seven cents a share above estimates. The restaurant chain's revenue missed forecasts, however, as same-store sales grew by a lower-than-expected 0.3 percent. Cheesecake Factory did announce a 20 percent dividend increase to 24 cents per share and expanded its share repurchase authorization.
Marriott — Marriott earned an adjusted $1.03 per share for the second quarter, five cents a share above estimates. The hotel chain's revenue matched forecasts. Marriott said slower economic growth impacted its results, but that it is still seeing solid demand in both the leisure and business segments.

AstraZeneca — The drugmaker saw second-quarter profit drop by almost a third, as generic competition weighed on sales of its best-selling Crestor cholesterol treatment.
