Genzyme Corp., of Cambridge, and iRobot Corp., of Burlington, reported earnings yesterday:
■ Genzyme’s fourth-quarter profit dropped to $23.2 million, or 9 cents per share, from $86.7 million, or 31 cents, in the year-earlier period. Revenue fell 8 percent, to $1.08 billion.
Excluding charges, Genzyme earned 31 cents per share. Analysts polled by Thomson Reuters had expected profit of 29 cents per share on revenue of $1.08 billion.
In June, the company shut its Allston plant to clean up viral contamination that had been slowing production of Cerezyme and Fabrazyme. The virus was not harmful to people, but the shutdown has been costly. Production restarted in September.

■ IRobot Corp., which makes military and home-cleaning robots, said fourth-quarter profit fell 5 percent - still higher than analysts expected.
Net income for the three months ended Jan. 2 was $5.1 million, or 20 cents per share, down from $5.4 million, or 21 cents. Analysts had forecast income of 16 cents per share.
