             American Technical Ceramics Corp. Announces
                   Third Quarter Financial Results

     Reports Highest Level of Quarterly Bookings since the Quarter
                          Ended June 30, 2000

    HUNTINGTON STATION, N.Y.--(BUSINESS WIRE)--May 3, 2007--AMERICAN
TECHNICAL CERAMICS CORP. (AMEX Symbol: AMK), a leading manufacturer of
high-performance electronic components, including capacitors and thin
film circuits for a broad range of commercial and military
applications, today announced financial results for the third fiscal
quarter and the nine months ended March 31, 2007.

    Net sales for the quarter ended March 31, 2007 increased 5.2% to
$23,872,000 from $22,690,000 in the comparable quarter in fiscal year
2006. Net sales for the nine months ended March 31, 2007 increased
12.8% to $67,563,000 from $59,870,000 in the comparable period in
fiscal year 2006. Management stated that the increases in net sales
for the three and nine month periods as compared to the comparable
periods in fiscal year 2006 were a result of higher sales volumes in
all of the markets the Company services, including strong shipments to
customers in the wireless infrastructure, military and fiber optic
markets which are showing strong demand for the Company's products in
RF/Microwave applications.

    Net income for the quarter ended March 31, 2007 amounted to
$1,865,000, representing diluted earnings per common share of $0.20,
compared with net income of $2,089,000, representing diluted earnings
per common share of $0.23 for the comparable quarter in fiscal year
2006. Management stated that the decrease in net income and diluted
earnings per common share for the three months ended March 31, 2007 as
compared to the comparable quarter in fiscal year 2006 was a result of
lower gross profit primarily due to higher than normal scrapping of
finished goods and work-in-process inventories. The Company
periodically scraps inventory based upon the mix of inventory relative
to near-term trends in bookings. In the most recent quarter, the
Company scrapped an additional $878,000 of inventory that likely would
have been scrapped over the next several quarters. This had a negative
impact on gross margins for the quarter. For the nine months ended
March 31, 2007, gross margins were approximately 37% which is in
keeping with management's expectations for the foreseeable future.

    Net income for the nine months ended March 31, 2007 increased
86.3% to $6,197,000, representing diluted earnings per common share of
$0.68, from net income of $3,327,000, representing diluted earnings
per common share of $0.38, for the comparable period in fiscal year
2006. Management stated that the increase in net income for the nine
months ended March 31, 2007 as compared to the comparable period in
fiscal year 2006 was primarily due to the increase in net sales and
the benefit of operating leverage inherent in the Company's business
model due to its relatively high level of fixed costs.

    Bookings for the three months ended March 31, 2007 were
approximately $25,938,000, a substantial increase over the levels
achieved in both the comparable quarter of fiscal year 2006 and the
second quarter of the current fiscal year. Management stated that
these increases are primarily due to the continued strong demand from
new and existing customers in the wireless infrastructure, medical and
fiber optic markets.

    Victor Insetta, President and Chief Executive Officer of the
Company, stated, "This past quarter we achieved the highest level of
quarterly bookings since the quarter ended June 30, 2000 and the
second highest level of quarterly bookings in the history of our
company. We are seeing strong demand for our products across all of
our markets. The robust bookings led to another strong quarter for
both sales and profit. Third quarter profit was offset to a degree by
a realignment of our inventories, but we do not expect this
realignment to impact future customer deliveries or gross margins
going forward. In fact, we anticipate that our higher level of
bookings will continue to drive operating leverage and greater
profitability. We have ample capacity to meet the expanding demand in
the market for our products and we are optimistic about our prospects
for the fourth quarter and into fiscal 2008."
