(1)      BASIS OF PRESENTATION:

         The accompanying unaudited interim consolidated financial statements of
American Technical Ceramics Corp. and Subsidiaries (the "Registrant") reflect
all adjustments (consisting of normal recurring accruals) which are, in the
opinion of management, necessary for a fair presentation of its consolidated
financial position as of March 31, 1999 and the results of its operations for
the quarter and nine months ended March 31, 1999 and 1998. These financial
statements should be read in conjunction with the summary of significant
accounting policies and notes to consolidated financial statements included in
the Registrant's Annual Report on Form 10-K for the year ended June 30, 1998.
Results for the three and nine months ended March 31, 1999 are not necessarily
indicative of results which could be expected the entire year.


(2)      SUPPLEMENTAL CASH FLOW INFORMATION:

         During the nine months ended March 31, 1999, significant non-cash
activities included (i) the purchase of approximately $100,000 of inventory in
exchange for common shares issued from treasury, (ii) the issuance of treasury
stock to pay approximately $211,000 in accrued bonus expenses, (iii) the
addition of property, plant and equipment through an increase in capital lease
obligations of approximately $105,000, and (iv) the issuance of treasury stock
to pay $167,000 in stock awards.

            ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                       CONDITION AND RESULTS OF OPERATIONS


         The following discussion and analysis should be read in conjunction
with the consolidated financial statements, related notes and other information
included in this Quarterly Report on Form 10-Q.

         Statements in this Quarterly Report on Form 10-Q that are not
historical fact may constitute "forward-looking statements" within the meaning
of the Private Securities Litigation Reform Act of 1995. All such
forward-looking statements are subject to risks and uncertainties, including,
but not limited to, the impact of competitive products, product demand and
market acceptance risks, increases in prices of raw materials, fluctuations in
operating results and delays in development of highly complex products and the
other matters listed in the Registrant's Annual Report on Form 10-K for the
fiscal year ended June 30, 1998 under the caption "Cautionary Statements
Regarding Forward-Looking Statements" and in the Registrant's other filings with
the Securities and Exchange Commission. These risks could cause the Registrant's
actual results for future periods to differ materially from those expressed in
any forward-looking statements made by the Registrant.


RESULTS OF OPERATIONS
---------------------

Three Months Ended March 31, 1999
Compared with Three Months Ended March 31, 1998
-----------------------------------------------

         Net sales for the three months ended March 31, 1999 increased less than
one percent to $9,954,000 as compared to net sales of $9,924,000 for the
comparable quarter in the prior fiscal year. Net sales in the aggregate and
across all major product lines were at similar levels to those achieved in the
comparable quarter of the prior fiscal year except for an increase in Thin Film
product sales and an offsetting decline in domestic hi-rel sales.

         The early signs of an overall market improvement that the Registrant
experienced during the latter part of the second quarter continued throughout
the third quarter. As a result, both orders and net sales were positively
impacted in the third quarter. In particular, orders for commercial domestic
core products were especially strong. The increased level of orders and net
sales the Registrant enjoyed in the third quarter has continued at about the
same level into the early weeks of the fourth quarter.

         The backlog of unfilled orders was $10,014,000 at March 31, 1999,
compared to $7,131,000, at March 31, 1998 and $6,308,000 at June 30, 1998. The
large increase in backlog is due to orders for non-core products, which were
booked in the first quarter of the current fiscal year, and are scheduled to be
shipped in significant amounts starting in the quarter ended March 31, 1999
through the quarter ended December 31, 1999. The backlog of domestic commercial
core products increased by approximately $600,000 over the prior quarter in the
current fiscal year. This increase was the primary reason for the overall
increase in backlog compared to December 31, 1998 of $9,465,000.

         Gross margin for the three months ended March 31, 1999 was 43% of net
sales as compared to 38% for the comparable quarter in the prior fiscal year.
The increase in gross margin was due to lower manufacturing overhead expenses
and material costs. These reductions were principally a result of a decrease in
manufacturing overhead expenses and improved product yields and manufacturing 
efficiencies.

         The Registrant achieved considerable improvement in the gross margin
percentage for the three months ended March 31, 1999 compared to the three
months ended December 31, 1998 when gross margin was 36% of net sales. This
improvement was primarily due to the significantly higher sales volume and a non
recurring provision for certain inventory reserves which negatively impacted the
three months ended December 31, 1998.

         Selling, general and administrative expenses for the three months ended
March 31, 1999 increased 3% to $2,246,000 as compared to $2,183,000 in the
comparable period in the prior fiscal year due to increases in accrued bonus
expenses and professional fees.

         Research and development expenses for the three months ended March 31,
1999 increased 15% to $506,000 as compared to $441,000 in the comparable period
in the prior fiscal year. This increase was primarily due to increases in
personnel expenses and depreciation of equipment used in product development
activities.

         Primarily as a result of the foregoing, net income for the three months
ended March 31, 1999 was $966,000, or $.25 per common share ($.25 per common
share assuming dilution), compared to net income of $792,000, or $.20 per common
share ($.20 per common share assuming dilution), for the comparable period in
the prior fiscal year.

Nine Months Ended March 31, 1999
Compared with Nine Months Ended March 31, 1998
----------------------------------------------

         Net sales for the nine months ended March 31, 1999 decreased 11% to
$27,097,000 as compared to net sales of $30,703,000 for the comparable period in
the prior fiscal year. The decrease in sales was primarily the result of the
previously announced decline in demand in the first six months of the current
fiscal year for the Registrant's core capacitor products in both foreign and
domestic markets, in large part as a result of the economic situation in Asia.

         Gross margin for the nine months ended March 31, 1999 was 36% of net
sales as compared to 42% for the comparable period in the prior fiscal year. The
decline in gross margin was due to lower sales volume and lower selling prices
on core capacitor products, higher raw material costs and an increase in certain
inventory reserves, most of which principally occurred in the first six months
of the current fiscal year.

         Selling, general and administrative expenses for the nine months ended
March 31, 1999 decreased 2% to $6,305,000 as compared to $6,410,000 in the
comparable period in the prior fiscal year, primarily as a result of decreases
in accrued bonus expenses and commission expenses. These expense reductions were
somewhat offset by planned increases to advertising and promotional expenses.

         Research and development expenses for the nine months ended March 31,
1999 increased 13% to $1,442,000 as compared to $1,271,000 in the comparable
period in the prior fiscal year. This increase was primarily the result of
increases in personnel expenses and depreciation of equipment used in product
development activities to support an increase in research and development
activities designed to accelerate the development of new products.

         As a result of the foregoing, net income amounted to $1,400,000, or
approximately $.36 per common share ($.36 per common share assuming dilution),
for the nine months ended March 31, 1999 compared to net income of $3,353,000,
or approximately $.86 per common share ($.83 per common share assuming
dilution), for the comparable period in the prior fiscal year.

LIQUIDITY AND CAPITAL RESOURCES
-------------------------------

         The Registrant's financial position at March 31, 1999 remains strong as
evidenced by working capital of $17,957,000 and stockholders' equity of
$31,575,000. The Registrant's current ratio at March 31, 1999 was 4.4:1 as
compared to a current ratio of 3.9:1 at June 30, 1998. The Registrant's quick
ratio at March 31, 1999 was 2.1:1 as compared to a quick ratio of 2.2:1 at June
30, 1998.

         Cash and investments decreased by $3,443,000 to $4,933,000 at March 31,
1999 from $8,376,000 at June 30, 1998, primarily as a result of an increase in
raw materials inventory and payments on accounts payable and accrued expenses.
Accounts receivable increased by $704,000 to $5,124,000 at March 31, 1999 from
$4,420,000 at June 30, 1998 due primarily to an increase in sales volume.
Inventories increased by $1,461,000 to $12,345,000 at March 31, 1999 from
$10,884,000 at June 30, 1998 due to higher raw material costs (particularly for
palladium) and a planned build up of palladium inventory as a hedge against
possible future adverse changes in price and/or availability of this material.
The Registrant currently believes it has an adequate supply of palladium to meet
its near term requirements and as a result does not currently plan on purchasing
any additional quantities of palladium at the high market prices that prevailed
in the quarter ended March 31, 1999. Accounts payable and accrued expenses
decreased by $821,000 to $3,820,000 at March 31, 1999 from $4,641,000 at June
30, 1998, primarily as a result of payments made during the first quarter.
Income taxes paid in the nine month period ended March 31, 1999 were $648,000.

         In November 1998 the Registrant renewed a $2,000,000 revolving
line-of-credit with NationsBank, NA ("NationsBank"), the successor to Barnett
Bank of Jacksonville, N.A. ("Barnett Bank"), and secured a $3,500,000
line-of-credit with NationsBank for equipment purchases. Both lines bear
interest at 2% above the three month rate for U. S. Dollar deposits on the
London Interbank Market. Principal under the revolving line-of-credit will be
repayable in eight quarterly installments commencing upon expiration of the
revolving period. The outstanding principal under the equipment line-of-credit
will be rolled over every six months into a self amortizing term note of not
less than four nor more than seven years. The equipment loan is secured by the
equipment purchases. Borrowing under both lines will be subject to compliance
with certain financial covenants, including maintenance of asset and liability
percentage ratios. As of March 31, 1999, the Registrant has borrowed an
aggregate total of $797,000 against the equipment line.

                       CONDITION AND RESULTS OF OPERATIONS



LIQUIDITY AND CAPITAL RESOURCES (continued)
------------------------------------------

         Capital expenditures for the nine months ended March 31, 1999 totaled
$2,885,000 of which $2,350,000 was for machinery and equipment. The Registrant
intends to use cash on hand and the new equipment loan noted in the preceding
paragraph to finance budgeted capital expenditures of approximately $983,000 for
the remainder of fiscal year 1999, primarily for additions to and replacements
of machinery and equipment.

         In June 1990, the Registrant announced its first stock purchase program
pursuant to which it was authorized to purchase up to $1,000,000 of its Common
Stock. In September 1998, the Board of Directors authorized the purchase of up
to an additional $1,000,000 of the Registrant's Common Stock under a second
stock purchase program. As of March 31, 1999 the Registrant had expended the
entire amount available under both programs and had purchased an aggregate of
475,000 shares.

YEAR 2000
---------

         The Registrant has completed all internal remediation and testing
efforts of computer systems that could be affected by the "Year 2000" problem.
The Registrant did not incur significant incremental expenditures related to its
Year 2000 activities. The Registrant is also presently obtaining representations
from its key suppliers and customers relative to their efforts to deal with the
Year 2000 problem. Based upon the representations obtained to date, the
Registrant does not anticipate significant additional expenditures or lost
revenues from Year 2000 failures of its key suppliers and customers. However, no
assurances can be made as to whether key suppliers and customers will become
Year 2000 compliant in a timely manner, if at all.
