Software firm Synchronoss (NASDAQ:SNCR) is plummeting post-earnings, and AT&T’s (NYSE:T) smartphone slowdown isn’t helping a bit. The softening in smartphone sales is said to be due to subsidy reductions and a weakening domestic market. SNCR obtains approximately one half of its revenue from AT&T, and currently projects second quarter revenue of between $65 million and $68 million, against a consensus of $68.6 million. Further, it sees only a 5 to 10 percent growth in AT&T sales in the current year, which is less than prior estimates.

One has commented that “Everyone hates his guts”.

Further, Sterne Agee suspects that analysts are concerned about both the acquisition’s price and Micron’s funding needs, and it values Elpida’s assets at more than $7 billion, far in excess of Micron’s reported bid of $2.5 billion.
