The pending acquisition will bolster IBM's already burgeoning portfolio of data management software. Sterling Commerce's capabilities, combined with IBM's own middleware and analytics products, will help companies respond more nimbly to sudden business challenges," IBM said.
Sterling Commerce's platform helps companies exchange documents and other information, as well as tie together business processes. The company competes with the likes of GXS, Inovis and Axway.
IBM is buying market share as well as technology. Sterling Commerce counts about 18,000 customers in the financial services, retail, manufacturing and other industries, according to a statement.
The deal is expected to close in the second half of this year.
Roughly 2,500 Sterling Commerce employees will join IBM's WebSphere division after the deal's close, according to a statement.
The acquisition is IBM's 57th since 2003, and follows its recent move to purchase application integration vendor Cast Iron Systems.
The Sterling deal was "not a very well-kept secret" in industry circles, with rumors floating around for quite some time, according to Forrester Research analyst Ken Vollmer.
Sterling Commerce is "a solid number two" after GXS in the B2B service provider space, Vollmer said. There could be additional acquisition activity in the market during the next couple of months, he added.
IBM chose Sterling based on business results and customer satisfaction levels relative to rivals in the market, said Craig Hayman , general manager of WebSphere, during a conference call Monday. "The difference was not trivial."
Sterling is itself the product of some consolidation, having purchased supply chain application vendor Yantra in 2005 and Nistevo, maker of transportation management software, in 2006.
With the pending deal, IBM is making a fresh run at the B2B service space, having sold off related businessesto GXS in 2004.
Big Blue's move to buy Sterling Commerce reflects the fact that vendors need dedicated B2B capabilities when trying to serve large customers, Vollmer said.
The companies bring respective strengths to the table, Altimeter Group analyst Ray Wang said in a blog post.
"[Sterling] built a reputation connecting businesses with their trading community of suppliers, customers, banks and transportation providers. IBM built a strong platform for inter-enterprise integration and SOA governance," he wrote. "Should the acquisition succeed, customers will gain integration across business networks and improve decision making through richer integration."
IBM intends to bring together Sterling's technology with its own "in a way that supports what the Sterling customer set and the IBM customer set wants to do," Hayman said.
