Merrimac Announces Second Quarter 2009 Results Reporting Fourth Consecutive Quarter of Strong Profits

WEST CALDWELL, N.J. August 17, 2009: 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 the results for the second quarter of 2009.

Second Quarter and First Six Months of 2009 Financial Highlights

Net sales for the second quarter of fiscal year 2009 increased 8.0% or $599,000 to $8.1 million compared to $7.5 million in the second quarter of fiscal year 2008. Net sales for the first six months of 2009 were $15.7 million up 18.5% over the first six months of 2008.

Second quarter gross profit increased 20.3% or $568,000 to $3.4 million in 2009 compared to $2.8 million in the second quarter of 2008. Gross profit for the first six months of 2009 was up 46.3% or $2.1 million over the first six months of 2008.

Gross profit margins increased to 41.6% and 43.0% for the second quarter and first six months of 2009, respectively, compared to 37.4% and 34.8% for the same periods last year.

Operating income for the second quarter of 2009 was $937,000 compared to $74,000 for the second quarter of 2008. Operating income for the first six months of 2009 was $1.9 million compared to an operating loss of $730,000 for the first six months of 2008. Strong second quarter operating income was achieved despite a high level of non-recurring professional fees expense. Action has been taken to reduce these expenses in future quarters.

Net income for the second quarter and the first six months of 2009 was $719,000 and $1.6 million, respectively, compared to a net loss of $30,000 and $895,000 in the second quarter and first six months of 2008, respectively.

Net income for the second quarter and first six months of 2009 was $0.24 and $0.53 per share, respectively, compared to a net loss of $0.01 and $0.30 per share, respectively, for the second quarter and first six months of 2008, respectively.

Chairman and CEO Mason N. Carter commented, “We are very excited to see the success of our focused strategy continuing as reflected in the Financial Highlights. The first half of fiscal year 2009 was very strong and with new orders meeting or exceeding our internal targets, we are well positioned to finish the second half of 2009 with profitable results.”

Second Quarter and First Six Months of 2009 Results

Net sales.

Net sales increased for the second quarter and the first six months of 2009. Net sales in the second quarter increased $599,000 or 8.0% to $8,089,000, from the second quarter of 2008 net sales of $7,490,000. For the first six months of 2009, net sales increased 18.5% or $2,448,000, to $15,696,000, compared to net sales of $13,248,000 for the first six months of 2008. Net sales for the second quarter and the first six months of 2009 increased due to the higher level of orders received during 2008 resulting in a larger backlog of orders to fulfill in fiscal year 2009 including increased sales of Multi-Mix® products to defense industry related customers.

Cost of sales and gross profit.

Gross profit and gross profit percentage increased for both the second quarter and first six months of 2009 compared to the same periods in 2008. Gross profit for the second quarter of 2009 increased $568,000 or 20.3%, to $3,367,000 compared to $2,799,000 for the second quarter of 2008. Gross profit margin for the second quarter of 2009 was 41.6% compared to 37.4% for the second quarter of 2008. Gross profit for the first six months of 2009 increased 46.3% or $2,137,000 to $6,749,000 from $4,612,000 in the first six months of 2008. Gross profit margin for the first six months of 2009 was 43.0% compared to 34.8% for the first six months of 2008.

The increase in gross profit in the second quarter and first six months of 2009 compared to the same periods in 2008 was primarily due to the increase in sales. The increase in sales also had a favorable impact on our gross profit percentage in the second quarter and first six months of 2009, allowing us to better absorb fixed manufacturing costs. Additionally, the improvement in the gross profit percentage was due in part to improved market conditions in the first half of 2009 compared to the soft market and competitive pricing pressure that existed in the first half of 2008.

Selling, general and administrative expenses.

Selling, general and administrative expenses were $2,313,000 for the second quarter of 2009, a slight decrease of $38,000 or 1.6%, compared to $2,351,000 in the second quarter of 2008. The decrease in such expenses for the second quarter of 2009 was primarily due to a decrease in selling and marketing expenses that were largely offset by higher professional fees. When expressed as a percentage of net sales, selling, general and administrative expenses decreased from 31.4% of sales in the second quarter of 2008 to 28.6% of sales in the second quarter of 2009. For the first six months of 2009 selling, general and administrative expenses were $4,672,000 compared to $4,595,000 in the first six months of 2008 an increase of $77,000 or 1.7%. The increase in such expenses for the first six months of 2009 was primarily due to higher professional fees that were largely offset by a decrease in selling and marketing expense. When expressed as a percentage of net sales, selling, general and administrative expenses decreased from 34.7% of sales in the first six months of 2008 to 29.8% of sales in the first six months of 2009.

Operating income (loss).

Operating income for the second quarter and first six months of 2009 was $937,000 and $1,901,000, respectively, compared to an operating income of $74,000 for the second quarter of 2008 and an operating loss of $730,000 in the first six months of 2008. The improvement in operating income for the second quarter and first six months of 2009 was primarily due to the improved gross profit resulting from increased sales and gross profit margins as well as the decrease in research and development costs compared to the first six months of 2008.

Income taxes.

Income tax expense was $200,000 and $243,000 in the second quarter and first six months of 2009 compared to $0 in the second quarter and first six months of 2008. The provision for income taxes in the second quarter and first six months of 2009 is based on the expectation that we will fully utilize our net operating loss carryforwards in 2009.

Discontinued operations.

Income from discontinued operations was $51,000 in the second quarter and first six months of 2009 compared to a loss from discontinued operations of $55,000 in the second quarter and first six months of 2008.

Net income (loss).

Net income for the second quarter and first six months of 2009 was $719,000 and $1,575,000, respectively, compared to a net loss of $30,000 for the second quarter of 2008 and a net loss of $895,000 in the first six months of 2008. Net income per share, basic and diluted, for the second quarter and first six months of 2009 was $0.24 and $0.53, respectively, compared to a net loss per share, basic and diluted, of $0.01 and $0.30 per share, respectively, for the second quarter and first six months of 2008.
