Earnings reports are in full swing and we are here to cover them all. From expectations exceeded and huge stock gains, to CEO’s being given their walking papers. Q1 (for most companies) reports go a long way towards explaining both the past and the future. The following is a concise preview of five of those reporting before the bell on Wednesday.

Earnings

Sprint Nextel Corporation (NYSE:S)

The third largest wireless provider in the States reports on Wednesday and this may determine how the fight between DISH and Softbank plays out in the acquisition/merger of Sprint Nextel Corporation (NYSE:S) . Prospective mergers aside, analysts have remained less than chuffed recently about Sprint’s earnings. They’ve widened their loss estimates for the just-ended quarter by $0.04 per share, with full-year 2013 consensus showing more than double those numbers.

Analysts are expecting a loss of $0.34 per share, compared to  a loss of $0.29 cents per share a year ago.

A year after being $8.73 billion, analysts expect revenue to fall 0.3 percent year-over-year to $8.71 billion for the quarter. For the year, revenue is projected to come in at $35.08 billion no matter what suitor takes Sprint to the altar.

AFLAC Incorporated (NYSE:AFL):

In the United States, Aflac is the number one provider of guaranteed-renewable insurance. In Japan, AFLAC Incorporated (NYSE:AFL) is the number one life insurance company in terms of individual policies in force. Aflac individual and group insurance products provide protection to more than 50 million people worldwide. With the strengthening Yen, this dividend beast is optimistic looking towards tomorrow’s reporting.

Consensus analysts estimates suggest that Aflac will show a profit of $1.62 per share on revenue of $6.12 billion. That would be slightly lower than a year ago, with the supplemental health and life insurer signaling in January that 2013 sales in Japan and the U.S. will slow compared to “strong” results the three previous years.

Angie’s List Inc (NASDAQ:ANGI):

Angie’s List passed the 2 million mark on Sunday, April 21, 2013.”It took us more than 16 years to get to one million paid households but just 18 months to double it,” said Angie Hicks, who in 1995 co-founded the company with CEO Bill Oesterle in Columbus, Ohio.

“Realizing such momentum in membership growth is truly a testament to our commitment to help consumers find the best local service providers,” she added. “Our members drive Angie’s List.”

That’s all well and good, but it won’t have a tremendous effect on tomorrow’s earnings report where the consensus is calling for an EPS of -$0.16 up from a year-to-year loss of $0.24 per share. Revenue is expected to rise year-over-year from $31.1 million to $55.5 million.

Crocs, Inc. (NASDAQ:CROX):

Crocs, Inc. (NASDAQ:CROX), together with its subsidiaries, engages in the design, manufacture, marketing, and distribution of footwear, apparel, and accessories for men, women, and children in the Americas, Europe, and Asia.

With unseasonably cooler spring weather and little to fall back on in terms of warmer footwear, analysts have lowered first quarter earnings per share to $0.30 from $0.33. This is compared to year-over-year earnings of $0.32 per share. Quarterly revenue is expected to come in at $305 million compared to $272 million in the same quarter last year. Annual revenue is expected to reach $1.3 billion compared to revenues of $1.1 billion in 2012.

Fusion-IO, Inc. (NYSE:FIO):

Fusion-IO, Inc. (NYSE:FIO) engages in the development, marketing, and sale of storage memory platforms for enterprise data. The United States represents its primary market. Fusion-IO, Inc. (NYSE:FIO) has beat analysts estimates 4 times in the past four quarters. Shareholders could expect a boost if the company beats estimates.

Wall Street analysts on average are looking for Fusion-io, which will report earnings after the close Wednesday, to report a loss of 7 cents per share on revenue of $80.48 million. This is down year-over-year from a profit of 6 cents per share on revenue of $94.2 million.
