MARVELL TECHNOLOGY GROUP LTD. REPORTS FIRST QUARTER FISCAL 2003 RESULTS

SUNNYVALE, CA. (MAY 23, 2002) - Marvell Technology Group Ltd. (NASDAQ: MRVL), a
technology leader in the development of extreme broadband communications
solutions, today reported financial results for its first fiscal quarter ended
May 4, 2002.

Net revenue for the first quarter of fiscal 2003 was a record $98.8 million, an
increase of 54% over net revenue of $64.2 million for the first quarter of
fiscal 2002 and a 19% sequential increase from net revenue of $82.8 million for
the fourth quarter of fiscal 2002. Net loss under generally accepted accounting
principles (GAAP), which includes the effect of acquisition-related expenses,
amortization of stock-based compensation and a special charge related to
facilities consolidation, was $30.9 million, or $0.26 per share (diluted), for
the first quarter of fiscal 2003, compared with net loss under GAAP of $105.0
million, or $0.93 per share (diluted), for the first quarter of fiscal 2002.

Pro forma net income, which excludes the effect of acquisition-related expenses,
amortization of stock-based compensation and a special charge related to
facilities consolidation, was $10.5 million, or $0.08 per share (diluted), for
the first quarter of fiscal 2003, compared with pro forma net income of $4.5
million, or $0.04 per share (diluted), for the first quarter of fiscal 2002.

"Q1 was a very strong quarter for the company," stated Dr. Sehat Sutardja,
Marvell's President and CEO. "During the quarter we delivered 19% sequential
increase in revenues, recorded very strong bookings and ended the quarter with
record backlog. We are experiencing this strength across both our data storage
and data communications businesses. Sales and bookings of our Gigabit Ethernet
products continue to accelerate as the transition of Gigabit to the desktop
gains momentum. We also continue to increase our market share in the data
storage market with the strong adoption of our integrated system-on-chip
solutions. Finally, our all-CMOS 802.11b Libertas(TM) baseband and RF solution,
for wireless LAN networking is receiving strong design momentum."
