                   MERRIMAC REPORTS FIRST QUARTER 2007 RESULTS

WEST CALDWELL, N.J., MAY 14, 2007: Merrimac Industries, Inc. (Amex: MRM), a
leader in the design and manufacture of RF Microwave components, subsystem
assemblies and micro-multifunction modules (MMFM(R)), today announced results
for the first quarter of 2007.

Sales for the first quarter of 2007 were $5,424,000, a decrease of $807,000 or
12.9 percent compared to the first quarter of 2006 sales of $6,231,000. The
sales decrease was due to a problem with purchased material that was utilized in
certain products. The Company has evaluated the material and found the problem
with the material does not affect the functionality and reliability of the
products. The customers purchasing these products agreed with the Company's
conclusions. This problem did cause shipment delays of approximately $1,000,000
of products that were expected to be sold in the first quarter of 2007.
Substantially all of the products impacted should be shipped during the second
quarter of 2007. Gross profit for the first quarter of 2007 was $1,782,000, a
decrease of $619,000 or 25.8 percent, and was 32.8 percent of sales as compared
to gross profit of $2,401,000 or 38.5 percent of sales for the first quarter of
2006. Gross profit percent in the first quarter of 2007 decreased from the first
quarter of 2006 due to the impact of the lower level of sales having to absorb
fixed manufacturing costs.

Operating loss for the first quarter of 2007 was $(1,220,000), compared to an
operating loss of $(457,000) for the first quarter of 2006. Operating loss for
the first quarter of 2007 was due to the lower gross profit from the decrease in
sales and higher research and development costs related to the Company's
Multi-Mix(R) products.

Net loss for the first quarter of 2007 was $(1,264,000) compared to a net loss
of $(441,000) for the first quarter of 2006. Net loss per share was $(.41) for
the first quarter of 2007, compared to net loss per share of $(.14) reported for
the first quarter of 2006. Net loss for the first quarter of 2006 included a tax
benefit of $35,000 or $.01 per share representing refundable Canadian provincial
technology tax credits for which the Company has qualified and lower net
interest expense.

Orders of $6,485,000 were received during the first quarter of 2007, an increase
of $2,540,000 or 64.4 percent compared to $3,945,000 in orders received during
the first quarter of 2006. Backlog increased by $1,061,000 or 8.6 percent to
$13,446,000 at the end of the first quarter of 2007 compared to $12,385,000 at
year-end 2006, due to the



shipment delays caused by the problem with the purchased material. The
book-to-bill ratio for the first quarter of 2007 was 1.20 to 1 and for the first
quarter of 2006 was 0.63 to 1.

Chairman and CEO Mason N. Carter commented, "We are currently working closely
with our key account customers in establishing new Multi-Mix(R) Solutions that
may become the foundation for the next-generation of integrated modules,
platforms and subassemblies.

               o    We received an Internal Research and Development contract
                    (IRAD) for Multi-Mix(R) integrated modules from a major
                    satellite customer. Final design and manufacture of the
                    first space IRAD qualified assembly modules have been
                    completed and delivered in April. We are continuing
                    co-design efforts with our customer in developing innovative
                    and enabling Multi-Mix(R) Microtechnology solutions that
                    offer size, weight, and cost solutions. Our customer design
                    engineers are co-designing with our design teams in offering
                    and optimizing compelling reasons for technology adoption by
                    their customers. These applications can be utilized for the
                    next-generation of military satellite communications.

               o    We received a contract from another key account satellite
                    customer to develop a variety of custom solutions for use in
                    beam forming communications networks for some of the largest
                    and most powerful satellites ever built.

               o    We continue our research and development investment focused
                    on our Integrated Multi-Mix(R) High Power Amplifier Resource
                    Module and continue to work on very significant developments
                    on highly integrated radar platforms."

Mr. Carter continued, "Our financial information includes:

     o    Cash of $3.7 million after the repurchase in March of 238,700 shares
          of Merrimac Common Stock at $9.00 per share for approximately $2.2
          million.

     o    Working capital of $10.1 million and a current ratio of 4.0 to 1.

     o    Research and development costs increased $139,000 for 2007 to support
          new Multi-Mix(R) products to be available later this year.

     o    First quarter 2007 book-to-bill ratio of 1.2 to 1."
