Martha Stewart did not acquire Emeril's Homebase, which includes Lagasse's 11 restaurants and corporate office.
Lagasse remains the host of the Food Network's "Essence of Emeril," but the food network channel ceased production of "Emeril Live" late last year, though it continues to air new episodes in 2008.
In a statement released Tuesday, the Food Network said, "We are happy to see that these two great brands will be combining forces and wish both of them the best. All of the Emeril's shows will remain on the network, and we also look forward to working with him on future projects."
Martha Stewart Living said the deal will "contribute immediately to our performance," adding $8 million in earnings before interest, taxes, depreciation and amortization. The acquired assets generated $14 million in revenue in 2007.
Martha Stewart Living expects the deal to close in the second quarter.
