Bel Reports 2009 Third Quarter Results

JERSEY CITY, New Jersey, October 29, 2009 — Bel Fuse Inc. (NASDAQ:BELFA and NASDAQ:BELFB) today announced preliminary unaudited financial results for the third quarter and first nine months of 2009.

"While revenue was lower for this year's third quarter than last year's, revenue increased slightly compared to the second quarter of 2009 and would likely have increased much more but for the shortage of trained labor in China.  Cash flow was strong, as were our core operating results.  Since July, 2009, order lead times have increased, and order backlog is up significantly.  These are positive signs for the future," said Daniel Bernstein, Bel's President and CEO.

"Our goal is to hire up to an additional 4,500 workers to meet the surge in backlog and bring our lead times down to normal.  This will temporarily increase labor expense due to inefficiencies during the new workers' training period.  We are adding workers as rapidly as we can in response to the improvement in business conditions, a considerable challenge because of the rapid ramp-up required, labor shortages in Southern China, and difficulties traditionally associated with hiring workers as we approach the Lunar New Year," Bernstein added.

Third Quarter Results

Net sales for the three months ended September 30, 2009 decreased to $45,283,000 compared to $66,964,000 for the third quarter of 2008.  The net loss for the third quarter of 2009 was $10,752,000.  This compares to net earnings for the third quarter of 2008 of $1,946,000.

The net loss for the third quarter of 2009 included pre-tax charges of $12.9 million ($12.9 million or $1.12 per share after tax) for impairment of goodwill and a $2.0 million license fee ($1.2 million or $0.11 per share after tax) paid in connection with the pending settlement of a lawsuit.  These costs were partially offset by a GAAP net gain of $0.5 million ($0.3 million or $0.03 per share after tax) on the sale of a portion of the Company's equity interest in Power-One, Inc., which reduced Bel's ownership to 4.1%.  This gain represents the difference between the sales price of the Power-One shares and the written-down value at December 31, 2008 (based on original cost, the Company actually realized a gain on the sale of Power-One shares in the amount of $21,000, or $13,000 after tax).  Net earnings for the third quarter of 2008 included a pre-tax labor severance charge of $0.3 million for the closure of the Company's manufacturing plant in Westborough, Massachusetts, and a non-cash, pre-tax charge of $1.4 million, primarily for the other-than-temporary impairment of Bel's holdings in Toko Inc. (TSE: 6801). In addition, the income tax provisions for both the 2009 and 2008 third quarters were reduced by the reversal of an accrual for uncertain tax positions, resulting from the expiration of certain statutes of limitations and the finalization of tax audits, partially offset by changes in estimates for prior years' taxes upon finalization of tax returns.
