said the Federal Trade Commission has made a second request for additional information on a product line before the two companies merge.
The companies expect to resolve the issue through a $17 million divestiture of a Fisher product line. Also, the companies say the antitrust waiting period should end in October.
Thermo and Fisher are working with the European Commission in its review of the proposed merger, which the companies expect to close at the end of the fourth quarter, pending regulatory and shareholder approval.
Thermo Electron's shares closed 11 cents lower at $39.21 Wednesday, while Fisher's shares fell 21 cents to $78.35.
