The U.S. financial crisis is taking a toll on mergers and acquisitions and share prices in the technology sector, causing the tech-heavy Nasdaq to slump to a new 52-week low Thursday, but industry watchers have an underlying confidence in the midterm scenario for IT vendor revenue.

Analysts such as Andrew Bartels, vice president at Forrester, are still convinced that as long as Congress passes a financial-sector rescue package, IT will not suffer annual spending declines in 2008 or 2009.

Many IT investors are running scared, nevertheless. On Monday, after Congress failed to pass a federal financial sector bailout plan, the Nasdaq plunged more than 9 percent to 1983.73, its third-worst percentage loss in history, hitting a 52-week low. In terms of percentage points, it was worse than the Dow Jones Industrial Average drop of 6.98 percent. Though the Nasdaq recovered somewhat in the following days, by Thursday afternoon it dropped to 1976.72, a new 52-week low.

Analysts this week downgraded the stock and earnings expectations for a variety of IT vendors, including Apple, Citrix, Digital River, Salesforce, AT&T, Akamai and Intel. Most analysts agree that the financial crisis is causing a credit crunch that will curb IT spending by consumers and corporations over the next few quarters. In a software sector research report, Citigroup analyst Brent Thill said, "we are cutting estimates on 11 of 22 stocks we cover to reflect the deteriorating macro environment."

The financial crisis and credit crunch are certain to affect M&A this year, despite some recent deals like this week's announcement that Hewlett-Packard will buy LeftHand Networks for US$360 million to bolster its storage virtualization and iSCSI product families. The collapse of big investment banks will certainly hamper leveraged buyouts -- acquisitions made with borrowed money. In addition, lower vendor share prices will make deals based on share offerings less attractive.

"Wherever the totals come in for 2008, it will certainly end four straight years of increasing M&A spending," said Brenon Daly, an analyst with The 451 Group, in a research report Thursday. "After approaching a half-trillion dollars worth of tech M&A in each of the past two years, deal flow this year is likely to be down about one-third from those levels." For the third quarter, the value of tech M&A deals dropped from $58 billion to $37 billion, Brenon reported.

Even companies with billions of dollars of cash on hand, such as Google and IBM, have been cautious about acquisitions, Brenon pointed out.
