Merrimac Reports Fourth Quarter and Fiscal Year 2005 Results

WEST CALDWELL, N.J., March 31, 2006: Merrimac Industries, Inc. (AMEX: MRM), a leader in the design and manufacture of RF Microwave components, subsystem assemblies and micro-multifunction modules (MMFM®), today announced results for the fourth quarter and fiscal year 2005.

Sales for the fourth quarter of 2005 were $7,002,000, a $784,000 or 10.1 percent decrease compared to fourth quarter 2004 sales of $7,786,000. The reduction in sales was due to lower orders from earlier in 2005 due to delays in expected satellite and defense programs. Gross profit for the fourth quarter was $2,662,000 or 38.0 percent of sales as compared to fourth quarter 2004 gross profit of $3,091,000 or 39.7 percent of sales.

Operating loss was $(147,000) for the fourth quarter of 2005, compared to operating income of $202,000 for the fourth quarter of 2004. Operating results for the fourth quarter of 2005 were lower due to a reduction of gross profit resulting from decreased sales, offset by slightly lower operating expenses. For the fourth quarter of 2004, operating income was reduced by $225,000 of employee incentive compensation and profit-sharing expense, which did not recur in 2005.

Net income for the fourth quarter of 2005 was $117,000 compared to net income of $209,000 for the fourth quarter of 2004. Net income was $.04 per diluted share for the fourth quarter of 2005 compared to net income of $.07 per diluted share for the fourth quarter of 2004. Net income for the fourth quarter of 2005 included a tax benefit of $250,000 or $.08 per share representing refundable Canadian provincial technology tax credits for which the Company has qualified. Net income for the fourth quarter of 2004 included a Canadian tax benefit of $143,000 or $.05 per share.

For fiscal year 2005, sales decreased 4.0 percent to $29,719,000, compared to sales of $30,949,000 for fiscal year 2004 as a result of lower orders during 2005 due to delays in expected satellite and defense programs. Gross profit for fiscal year 2005 was $12,214,000 or 41.1 percent of sales as compared to $12,910,000 or 41.7 percent of sales for fiscal year 2004.

Operating income for fiscal year 2005 totaled $742,000 as compared to operating income for fiscal year 2004 of $1,367,000. Operating results for 2005 were lower due to a reduction of gross profit resulting from decreased sales and the increase in research and development costs to support new Multi-Mix® products to be available in 2006. For fiscal year 2004, operating income was reduced by $225,000 of employee incentive compensation and profit-sharing expense, which did not recur in 2005.

Net income for 2005 was $761,000 or $.24 per diluted share compared to $1,198,000 or $.38 per diluted share for 2004. As noted before, net income for 2005 included a tax benefit of $250,000 or $.08 per share related to refundable Canadian provincial technology tax credits, while net income for 2004 included a Canadian tax benefit of $218,000 or $.07 per share.

The backlog at year-end 2005 was $13.1 million, an increase of $194,000 or approximately 1.5 percent compared to the backlog of $12.9 million at year-end 2004. Orders received during the fourth quarter of 2005 totaled $8.4 million and were approximately 20 percent above fourth quarter 2005 sales. Orders received for fiscal year 2005 totaled $29.9 million and were slightly above fiscal year 2005 sales.

Chairman and CEO Mason N. Carter commented, “Other 2005 financial results reflecting consistent performance include:
