The tail-end summer heat has been heavily attributable to the mergers and acquisitions blaze. Companies are putting their cash to work on public companies fetching discounted equity prices in a market environment favoring safety (e.g., gold and bonds).

Recently, Hewlett-Packard (HPQ) edged out Dell (DELL) for the 3Par deal award. With an eye toward the future, HP displayed their powerful desire to own a piece of the data storage and cloud computing pie. Since Dell ended empty-handed, it's only a matter of time before the next stock is a tech heavyweight's prime target.

Over the past few years, some of the big players in tech – such as Oracle Corporation (Nasdaq: ORCL), SAP (AG) (NYSE: SAP) and Microsoft Corporation (Nasdaq: MSFT) – have been been aggressive with M&A. Even after the dot-com bust, there is still a lot of excess capacity in the tech world.

However, according to a report from the 451 Group, it looks like the recent instability in the financial markets is taking a toll on things. After all, Lehman Brothers no longer exists and other major investment banks have radically changed their business models, such as Morgan Stanley (NYSE: MS) and Goldman Sachs Group, Inc. (NYSE: GS).

Looking at Q3, the dollar-value of tech deals plunged by a third to $37 billion. In fact, there were only six deals in excess of $1 billion.

Then again, with the tight credit squeeze, it's exceedingly difficult to get deals done. For instance, there were only 12 leveraged buyouts in Q3, which compares to 36 in the same period a year ago.

Of course, the financial shakeout has made many tech targets attractive. But, the problem is that the mega corporate buyers have also seen sharp reductions in market caps. And if the US economy continues to deteriorate, it's likely to cut into tech spending, making things even worse for dealmaking.

On its face, it looks like the tech M&A market is holding up nicely -- despite the credit crunch and slowing economy. For example, in Q1, tech M&A came to $92 billion, which was down from last year's $100 billion (this is according to the 451 Group).

Good, huh? Well, as usual, statistics can be deceiving. Keep in mind that Microsoft's (NASDAQ: MSFT) $45 billion bid for Yahoo! (NASDAQ: YHOO) was a huge factor (interestingly enough, there are signs that the deal may not go through).

In fact, there was a 50% reduction in deals in excess of $1 billion (only 11). For the most part, larger transactions need debt financing -- which is in short supply nowadays. After all, last year we saw a rush by private equity firms into the tech sector.

According to the 451 Group, it also looks like strategic buyers are getting skittish. Simply put, they are concerned about the macroeconomy. And something else: with lower stock prices -- with companies like Microsoft, Apple (NASDAQ: AAPL), Google (NASDAQ: GOOG) and VMware (NYSE: VMW) -- it is more dilutive to do deals.
