Thursday's Early Winners & Losers

CACI (CAI) plunged 14% in extended trading Wednesday after the information-technology company sharply cut its fiscal 2007 guidance, citing waning demand for certain contracts with the Department of Defense. It now expects to see earnings between $2.45 a share and $2.65 a share, down from the range announced in August of between $2.91 a share and $3.15 a share. Revenue will likely be between $1.88 billion and $1.95 billion. The prior sales range was between $2 billion and $2.1 billion. Analysts are looking for $3 a share on sales of $2 billion. Shares were sliding $7.90 to $47.20.

Ibis Technology (IBIS) surged after the Danvers, Mass.-based small-cap estimated it would swing to a 2006 profit of $400,000, or 4 cents a share, compared with a loss of $9.2 million, or 86 cents a share, in 2005. The semiconductor-component maker also forecasts revenue will soar to $14 million, up from $600,000 last year. Shares were adding 26 cents, or 16.5%, to $1.83.

Electro Energy (EEEI) jumped on word the specialized-battery maker will favorably restate results for the 2006 quarters ended June 30 and Sept. 30. Stockholders' equity is expected to rise about $9 million as the Danbury, Conn., company revalues its April 2006 purchase of certain Floridian battery-manufacturing assets. Shares were gaining a dime, or 6.7%, to $1.60.

Apple (AAPL) gained after the computer maker reported profits well above Wall Street expectations. Fourth-quarter income ratcheted up to $1 billion, or $1.14 a share, crushing estimates by 36 cents, according to Thomson Financial. Last year the Cupertino, Calif.-based company earned $565 million, or 65 cents a share. In addition, revenue grew to $7.11 billion from last year's $5.75 billion, handily beating the $6.42 billion consensus. Shares were trading up 98 cents, or 1%, to $93.97.
