Tech Earnings Remain in Focus

Corning , CA and Sun were the latest tech bellwethers to run afoul of Wall Street’s expectations late Tuesday.

Corning reported results and guidance that were largely in line with analysts’ estimates, but with revenues just under expectations and analysts worried about flat panel display pricing and telecom sales, Corning’s stock sank 7% after hours. Sales rose 17% in the quarter to $1.2 billion, just under $1.21 billion estimates.

CA met estimates on a 5.5% increase in sales to $967 million, but said its March quarter earnings and sales will come in just under estimates. That was good for a 3% loss after hours.

Sun’s stock managed to tick up a few pennies despite missing estimates with a 3-cent loss on $3.34 billion in revenues, up 17% from the year-ago quarter. The company burned through $191 million in the quarter and has $4.3 billion in cash.
