NEW YORK (CNN/Money) - No economic data is due and no companies will report earning Friday, but after the bell Thursday a handful of technology companies reported earnings, including software maker Adobe Systems Inc. and Linux systems operator Red Hat Inc.

Adobe (ADBE: Research, Estimates), best-known for its Acrobat software, reported quarterly net income of $109.4 million, or 44 cents a share, up from 27 cents a share a year earlier. The company cited strong demand for its increased sales, but shares fell 2.5 percent in after-hours trade on Inet.

Red Hat (RHAT: Research, Estimates), a leading distributor of Linux software, said its quarterly revenue jumped more than 50 percent from a year earlier and that quarterly profit climbed to $10.7 million, or 5 cents per share, compared with 1 cent a year earlier. Even so, shares plunged 8.4 percent on Inet after the earnings announcement.

But Solectron (SLR: Research, Estimates) shares rose 1.4 percent in after-hours trade following the company's earnings statement. The contract electronics manufacturer reported revenue increased 29 percent from a year earlier and that third-quarter earnings hit $21.3 million, or 2 cents a share, reversing a year-ago net loss of $3.10 billion, or $3.74 a share.

Solectron also forecast fourth-quarter earnings above Wall Street estimates.

Also reporting after the bell, health management provider American Healthways (AMHC: Research, Estimates) announced third-quarter revenue jumped 56 percent from a year earlier, in line with its earnings guidance for the quarter. Net income increased 64 percent and earnings per diluted share increased 57 percent to 22 cents a share from 14 cents a share a year earlier.

American Healthways stock soared 9.9 percent after the bell on Inet, after edging higher 0.1 percent in active trade Thursday.

Consumer health products maker Chattem Inc. (CHTT: Research, Estimates) said quarterly net earnings fell slightly because of litigation and debt charges but that revenue rose on strong sales. Including $5.1 million in charges, the company posted earnings of $7.2 million, or 36 cents per share, compared with 38 cents a share a year earlier. Shares jumped 4.9 percent in after-hours trading on Inet.

Southwest Airlines (LUV: Research, Estimates) announced late Thursday it expects to post a second-quarter profit, and that it will see lower unit costs for the second half of 2004 from a year earlier. Chief Executive Jim Parker told reporters that the discount-air carrier's costs likely peaked in the second quarter and that items like increased productivity should push costs lower, despite record high fuel prices.

Shares edged higher 0.3 percent after the bell, after settling up 0.3 percent in active trade on the New York Stock Exchange.
