Nov 28 (Reuters) - Chipmaker Marvell Technology Group Ltd forecast strong results for the current quarter while delivering higher-than-expected earnings and revenue for the third quarter, boosted by robust demand for its networking and connectivity chips.
Shares of Hamilton, Bermuda-domiciled Marvell rose 2 percent in after-market trading to $23.75.
The results come days after Marvell said it would buy smaller rival Cavium Inc for about $6 billion, seeking to expand its wireless connectivity chip business.
Marvell expects adjusted earnings of 29 to 33 cents per share and revenue of $595 million to $625 million in the quarter ending January 2018.
Analysts on average were expecting a profit of 27 cents per share and revenue of $590.2 million, according to Thomson Reuters I/B/E/S.
Marvell mainly makes chips used for reading and writing data on hard-disk and flash drives.
Revenue from that business slipped in the third quarter ended Oct. 28, but revenue rose in its other two businesses - networking and WiFi connectivity chips - which together make up 41 percent of overall revenue.
The company's net income from continuing operations rose to $149.4 million or 30 cents per share, from $83.2 million or 16 cents per share. Excluding items, Marvell earned 34 cents per share.
Revenue fell 1.2 percent to $616.3 million.
