Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Shares of life sciences company Cambrex (CBM) shot higher by as much as 16% following the release of its fourth-quarter earnings results.

So what: For the quarter, Cambrex reported a 4.8% increase in revenue to $69.9 million, as gross margin expanded 60 basis points to 30% thanks to a better product mix and higher volumes of active pharmaceutical ingredients, or APIs, being sold. Net income rose to $44.2 million from just $3 million in the year prior because of a huge one-time tax benefit. Adjusting for one-time costs, Cambrex earned $0.26, which is double what Wall Street had expected. Looking ahead, Cambrex anticipates sales growth of 8%-12% in 2013 and EBITDA growth of 8%-18% to a range of $62 million-$68 million. This would imply full-year revenue at a midpoint of $303 million, and EPS getting close to $1 -- perhaps $0.01 or $0.02 shy. The lone analyst estimate for 2013 is calling for only $298.1 million in sales and $0.95 in EPS.

Now what: This was another great quarter for Cambrex, even if you consider that foreign currency translations knocked 90 basis points off its top-line revenue results. Its APIs are important components for many generic pharmaceutical companies, and, with opinion growing for cheaper alternatives to branded drugs, there's no reason to believe Cambrex can't continue to grow. As with all generic drug makers, it'll contend with margin contraction as competition heats up, but at just 13 times this year's earnings, I feel it could march even higher.
