NEW YORK ( TheStreet) -- Shares of EXFO Inc. ( EXFO) rose in extended trading on Tuesday after the Canadian provider of telecommunications testing products reported its fiscal fourth-quarter results.

After the bell, the company said it earned $5 million, or 8 cents a share, on sales of $65.2 million for the three months ended Aug. 31, up from a loss of $1.2 million, or 2 cents a share, on sales of $36.5 million in the same period a year earlier. On a continuing operations basis, EXFO said it earned 7 cents a share in the August quarter. Wall Street's consensus estimate was for a profit of 2 cents a share.

For the company's current fiscal first quarter, ending in November, EXFO said it expects earnings of 17 to 21 cents a share on a GAAP generally accepted accounting principles basis, including an estimated gain of 22 cents a share from the divestiture of its Life Sciences and Industrial division, as well as other items. EXFO also left intact its outlook for sales of $61 million to $66 million in the quarter, despite the unit sale.

The stock was last quoted at $6.17, up 6.2%, on volume of around 18,000, according to Nasdaq.com. Based its regular session close at $5.81, the shares had already appreciated more than 48% so far in 2010.

Another stock getting a lift in afterhours action was FormFactor ( FORM), which tacked on 5.2% to $9.10 on volume of roughly 17,000. The Livermore, Calif.-based provider of chip testing products said Tuesday in a filing with the Securities and Exchange Commission that it cut 60 jobs as part its decision to stop a transition of manufacturing operations to a plant in Singapore.

The company also said it expects to record a total of $750,000 in charges related to severance payments and retention bonuses stemming from the restructuring, along with additional charges of roughly $8 million from asset impairment.

Getting a haircut in extended trades was Linear Technology ( LLTC), which saw its stock fall almost 4% to $30.35 on volume of around 350,000.

The Milpitas, Calif.-based semiconductor maker reported in-line results for its fiscal first quarter ended in September, but gave a disappointing revenue outlook for the current second quarter ending in December.

"As we enter the December quarter there is more uncertainty than in recent quarters which makes forecasting difficult," said Lothar Maier, the company's CEO, in a press release. "Although we had another positive book-to-bill ratio, bookings decreased as the quarter progressed. Customers are more confident in their ability to get parts and therefore may continue to adjust inventory levels and safety stock downward."

Linear Technology said it now expects revenue to come in between flat or down as much as 4% on a sequential basis from its total of $388.6 million in the first quarter.

The current average estimate of analysts polled by Thomson Reuters is for revenue of $384.1 million in the December period.
