We've consolidated 60-plus tech M&A deals (and counting) from this year in our ongoing . Note that in many deals, the vendors don't publicly say how much they're forking over for their prize acquisitions, but here, we'll recap the top 15 based on publicly disclosed transaction values:
1. Verizon Wireless-Alltel: $28.1 billion (includes $22.2 billion in debt)
Apparently tired of being the second-largest U.S. wireless carrier, Verizon Wireless is vaulting past AT&T via this buyout of the nation's fifth-largest wireless carrier. After adding Alltel's 13 million customers to its ranks, Verizon will have the most subscribers in the United States, with around 80 million.

Some worry that HP might keep its product and services for customers' comfort. According to the company's latest financial announcement, "HP Services (HPS) revenue increased 99% to $8.6 billion, led by $3.9 billion revenue resulting from the EDS acquisition." Apart from that buy, by 10% in 2008 over the previous year.
3. Oracle-BEA: $8.5 billion

Some said at the outset that IBM might also be a winner from this deal by exploiting fear, uncertainty and doubt surrounding the middleware vendor's integration into Oracle. In July, Oracle spelled out its : All BEA products will continue under existing support timelines, with "no forced migration at all," Oracle CEO Charles Phillips said at the time.
But moving forward, the combined company's middleware and infrastructure catalog will be broken into three categories: strategic; "continue and converge" and "maintenance," said Thomas Kurian, senior vice president, Oracle Fusion Middleware. Oracle also specified that BEA WebLogic Server will be Oracle's lead apps server, even though Oracle will continue to work on its own.

One more for good measure
Cisco-Nuova: $678 million?
We weren't quite sure what to do with the announced in April. It's complicated in that Cisco already owned 80% of the switch maker. The reason we say it's difficult to judge the value of this transaction is that Cisco says the maximum potential payout for Nuova could reach $678 million based on the revenue of Nuova products over three measurement periods. The first measurement period will be early in Cisco's fiscal year 2010, the second measurement in late fiscal year 2010, and the third in mid fiscal year 2011. Nuova is behind Cisco's Nexus 5000 .
