Whirlpool - The appliance maker reported first-quarter profit of $1.97 per share, excluding certain items, four cents above estimates. Revenue was shy of consensus, but Whirlpool was able to expand profit margins through higher prices and cost cuts.
WellPoint - The health insurer earned $2.94 per share, excluding certain items, for the first quarter, well above estimates of $2.38. Revenue fell short of estimates, but WellPoint raised its full-year profit outlook. It expects to see increased benefits from its acquisition of Medicaid specialist Amerigroup in December
Sprint Nextel - Sprint reported a smaller-than-expected quarterly loss of $0.21 per share, compared to analysts' estimates of a $0.33 per share loss. That came despite a larger-than-expected loss of subscribers as it shut down its Nextel network.
Thermo Fisher Scientific - The lab equipment maker reported first-quarter profit of $1.37 per share, excluding certain items, eight cents above estimates.
Eli Lilly - The drugmaker earned $1.14 per share for the first quarter, nine cents above estimates, while revenue was essentially in line. Profit margins improved, despite a lack of revenue growth.
Apple - Apple reported fiscal second-quarter profit of $10.09 per share, nine cents above estimates, with revenue also beating consensus. Apple also increased its quarterly dividend by 15 percent to $3.05 per share, and its stock buyback program by $50 billion to a total of $60 billion. However, its projected current-quarter revenue is below Street estimates.
AT&T - AT&T earned $0.64 per share for the first quarter, excluding certain items, in line with Wall Street estimates. Revenue was slightly below expectations, and although the profitability of the company's wireless unit rose, its customer additions did not keep pace with those of rival Verizon Communications.
Yum Brands - Yum earned $0.70 per share for the first quarter, ten cents above estimates, with revenues in line with forecasts. The parent of KFC, Taco Bell, and Pizza Hut also said the bird flu issue is continuing to negatively impact comparable store sales in China, but it reaffirmed its prior outlook for full year earnings.
Amgen - Amgen reported first quarter profit of $1.96 per share, excluding certain items, 12 cents above estimates, but revenues were short of forecasts both overall and for many of its top-selling treatments.
Broadcom - The company posted first quarter earnings of $0.65 per share, excluding certain items, nine cents above estimates, while revenues also exceeded consensus. The chipmaker sees the majority of its growth for 2013 coming from sales to manufacturers of smartphones.

Juniper Networks - Juniper reported first quarter profit of $0.21 per share, excluding certain items, in line with estimates. But the network equipment maker's second quarter forecast of $0.22 - $0.26 per share is below consensus, with weaker spending by the government and the financial services industry seen as the primary reasons.
Norfolk Southern - The Dow Transport component beat estimates by 24 cents with first quarter profit of $1.41 per share. The rail operator saw transport volumes increase despite weakness in coal shipping.
Panera Bread - Panera missed estimates by six cents with first quarter profit of $1.59 per share, excluding certain items, and the restaurant operator's revenues also fell short of Street estimates. Same-store sales were up 3.3 percent, short of the 4.2 percent consensus forecast.
