Check out which companies are making headlines before the bell on Wednesday:
Google - Google posted quarterly profit of $10.59 per share, 17 cents above estimates. Revenue, however, was slightly short and analysts have been highlighting the fact that the fastest growing parts of Google are in lower margin businesses.
Coach - The luxury goods maker reported fiscal second quarter profit of $1.23, below estimates of $1.28, with revenues also missing estimates. CEO Lew Frankfort says holiday season sales were disappointing.

McDonald's - The restaurant chain earned $1.38 per share for the fourth quarter, five cents above estimates, with revenue also beating consensus. However, the company does see negative January global comps, compared to estimates of a 0.2 percent increase.
U.S. Airways - The airline reported fourth-quarter profit of $0.26 per share, excluding certain items, compared to Street estimates of $0.19.
Motorola Solutions - The company earned $1.10 per share for the fourth quarter, eight cents above estimates, with revenue essentially in line with estimates. Results were helped by increased government spending.
WellPoint - The health insurer earned $1.03 per share, excluding certain items, for the fourth quarter, eight cents above estimates. WellPoint did give a cautious outlook for 2013, as it expects a membership drop this year.
Wells Fargo - Wells Fargo has increased its quarterly dividend by 14 percent to $0.25 per share, from $0.22. The bank plans to return even more capital to shareholders once it gets permission to do so from the Federal Reserve.

International Business Machines - IBM earned $5.39 per share for the fourth quarter, 14 cents above estimates, with revenue also beating consensus. It also predicted 2013 earnings slightly above Street estimates. IBM is benefiting from improved tech spending as well as growth in emerging markets.
Texas Instruments - TI reported fourth-quarter profit of $0.36 per share, two cents above estimates, with revenue essentially in line with estimates. The chipmaker's current-quarter outlook does fall largely below estimates, as demand continues to be weak in markets like Europe and China.
Comerica – The bank is raising its quarterly dividend by 13 percent to $0.17 per share from $0.15.
Norfolk Southern – The company earned $1.30 per share for the fourth quarter, beating estimates of $1.19, with revenue in line with estimates. The rail operator is seeing growth in its merchandise and intermodal businesses, but is also bearing the impact of slumping coal revenue.
CSX – The railroad operator is reporting a similar story to its rival, beating estimates by four cents with fourth-quarter earnings of $0.43 per share, with the positive and negative impacts from the same sources as Norfolk Southern.
Intuitive Surgical - The maker of surgical products earned $4.25 per share for the fourth quarter, $0.21 above estimates, with revenue also topping consensus. Its results were helped by increasing sales of its da Vinci surgical robots.
Advanced Micro Devices - AMD lost $0.14 per share for the fourth quarter, a loss that was $0.06 smaller than analysts had forecast. But the chipmaker's loss was wider than its loss in the year-earlier period, as PC demand continues to soften.
Unilever – The consumer products maker saw its shares hit a record overseas, as it reported 2012 sales growth of 6.9 percent, above analysts' estimates. It did caution, however, that its markets remain difficult.
Research In Motion – RIM has released its new enterprise management system, paving the way for its biggest customers to use the new BlackBerry 10 smartphones due for release next week.
St. Jude Medical - The maker of medical products reported quarterly profit of $0.92 per share, excluding certain items, two cents above estimates.
