Bel Reports First Quarter Results

JERSEY CITY, New Jersey, April 27, 2005 . . . Bel Fuse Inc. (NASDAQ:BELFA & NASDAQ:BELFB) today announced financial results for the first quarter of 2005.

For the three months ended March 31, 2005, revenue increased 7% to $45,438,000 from $42,357,000 for the first quarter of 2004. Net earnings were $4,313,000, or $0.37 per diluted share, compared to $4,655,000, or $0.41 per diluted share, for the same period last year.

"We were pleased by the increase in revenue, especially because the first quarter was our weakest quarter of the year in both 2003 and 2004. Gross margin was reduced slightly compared to prior year by an unfavorable mix of sales, although the unusually high tax rate due to an accrual for higher taxes in Asia was primarily responsible for the decline in earnings for the quarter," said Daniel Bernstein, Bel's President.

Bernstein continued, "The acquisition of Galaxy Power Inc. we completed on March 23, 2005 brought to Bel a strong team of engineering professionals and an extensive line of custom power products that have proven themselves in the marketplace. We already have eliminated approximately $600,000 of annualized overhead costs, and we anticipate additional savings as we integrate the Galaxy facility and its portfolio of power products into Bel's global manufacturing and sales channels."

Bernstein added, "On April 4, 2005, Bel reiterated its interest in pursuing a business combination with Artesyn Technologies, Inc., and our willingness to begin negotiations. However, in light of the recent Galaxy acquisition and additional investments in our power group, we also notified Artesyn that we would not remain open to such discussions indefinitely and that a failure of Artesyn to respond in a timely manner could diminish Bel's valuation of Artesyn. As of today there has been no response from Artesyn."

At March 31, 2005, Bel had cash, cash equivalents and marketable securities of approximately $88,600,000, working capital of approximately $115,300,000, a current ratio of 4-to-1, total long-term debt of $6,000,000 (of which $2,000,000 is current) and shareholders' equity of approximately $179,800,000.
