STOCKS TO WATCH: ATMI, Egghead.com, Nextlink, Priceline.com and Rainbow Technologies

ATMI shares will be moving Thursday after company officials late Wednesday announced for secondary offering of 4 million shares of common stock.

ATMI, which develops diamond and silicon carbide semiconductors, has about 26.2 million shares outstanding.

The company said it expects that the timing and size of the offering are dependent on market conditions and other factors, with selling stockholders expected to sell a majority of the shares being sold.

Its shares closed off 13/16 to 45 5/8.

Egghead.com beat Street estimates in its fourth quarter, losing $38.9 million, or $1.05 a share, on sales of $146.1 million. But that might not be enough to help the struggling stock.

First Call consensus expected it to lose $1.10 a share in the quarter.

Egghead.com shares closed up 1 5/8 to 12 3/4 ahead of the earnings report but retreated in after-hours trading.

The $146.1 million in sales marks a 45 percent improvement from the year-ago quarter when it lost $12 million, or 36 cents a share, on sales of $100.9 million.

The $38.9 million loss does not include charges associated with its acquisition of OnSale Inc. (Nasdaq: ONSL).

For the year, Egghead.com lost $155 million, or $2.04 a share, on sales of $514.8 million.

Its shares have struggled of late, falling to a low of 10 3/4 earlier this month after peaking at 47 1/2 in March.

Six of the eight analysts tracking the stock maintain a "hold" recommendation.

Analysts are expecting it to lose $1.88 a share in fiscal 2000.

Cellular telephone pioneer Craig McCaw's Eagle River Investments LLC plans to sell 3.5 million shares in the telecommunications company, currently valued at $410 million, to fund other ventures. Nextlink shares rose 5 9/16 to 117 1/4.

The online travel site will be on the move Thursday after adding former Citigroup CFO Heidi Miller to its executive team.

Miller, 46, will join the Priceline board of directors, and be senior vice president, strategic planning and administration, the company said.

Miller succeeds former CFO Paul Francis, who was named to the board of directors of Walker Digital, the intellectual- property firm founded by Priceline founder and Vice Chairman Jay Walker. Francis will also join two of Priceline's affiliated companies, becoming CFO of Priceline WebHouse Club and non-executive chairman of Priceline Perfect YardSale.

Priceline.com shares moved up more than $4 a share to 55 3/4 following the announcement.

Rainbow topped Street estimates in its fourth quarter Wednesday, earning $3.1 million, or 25 cents a share, on sales of $35.4 million.

First Call consensus expected the Internet security software developer to earn 23 cents a share in the quarter.

Its shares closed up 1 3/4 to 35 ahead of the earnings report.

The $35.4 million in sales marks a 15 percent improvement from the year-ago quarter when it lost $2.4 million, or 20 cents a share, on sales of $30.7 million.

For the year, Rainbow earned 67 cents a share on sales of $121.1 million compared to a profit of 21 cents a share on sales of $109.2 million in fiscal 1998.
