US computer giant Dell has agreed a deal to buy data storage company EMC for $67bn (£44bn).
EMC shareholders will receive $33.15 per share, $24.05 of which will be in cash.
If approved by regulators, the deal would be the biggest in history between two technology companies.
Falling demand for PCs means Dell is looking to expand into more lucrative businesses, and it has identified data storage as a key growth area.
“Our new company will be exceptionally well-positioned for growth in the most strategic areas of next-generation IT ,” said Dell boss Michael Dell.
EMC boss Joe Tucci said: “The waves of change we now see in our industry are unprecedented and, to navigate this change, we must create a new company for a new era”.
Mr Dell will be chairman and chief executive of the combined group that, Dell said, would be the world’s “largest privately-controlled, integrated technology company”.
