Summary of Significant Accounting Policies

Consolidation

The consolidated financial statements include the accounts of Ducommun Incorporated and its subsidiaries (Ducommun or the
Company), after eliminating intercompany balances and transactions. The consolidated balance sheet is unaudited as of April 3, 2010, the consolidated statements of income are unaudited for the three months ended April 3, 2010
and April 4, 2009 and the consolidated statements of cash flows are unaudited for the three months ended April 3, 2010 and April 4, 2009. The interim financial statements reflect all adjustments, consisting only of normal recurring
adjustments, which are, in the opinion of management, necessary for a fair presentation of the results for the interim periods presented. The financial information included in this Form 10-Q should be read in conjunction with the Companys
consolidated financial statements and related notes thereto included in the Form 10-K for the year ended December 31, 2009. The results of operations for the three months ended April 3, 2010 are not necessarily indicative of the results to
be expected for the full year ending December 31, 2010.

Ducommun operates in two business segments. Ducommun
AeroStructures, Inc. (DAS), engineers and manufactures aerospace structural components and subassemblies. Ducommun Technologies, Inc. (DTI), designs, engineers and manufactures electromechanical components and subsystems, and
provides engineering, technical and program management services (including design, development, integration and test of prototype products) principally for the aerospace and military markets. The significant accounting policies of the Company and
its two business segments are as described below.

Earnings Per Share

Basic earnings per share is computed by dividing income available to common shareholders by the weighted average number of common shares
outstanding in each period. Diluted earnings per share is computed by dividing income available to common shareholders plus income associated with dilutive securities by the weighted average number of common shares outstanding plus any potential
dilutive shares that could be issued if exercised or converted into common stock in each period.

Comprehensive
Income

Certain items such as unrealized gains and losses on certain hedging instruments and pension liability
adjustments are presented as separate components of shareholders equity. The current period change in these items is included in other comprehensive loss and separately reported in the financial statements. Accumulated other comprehensive
loss, as reflected in the Consolidated Balance Sheets under the equity section, is comprised of a pension liability adjustment of $3,146,000, net of tax, and an interest rate hedge mark-to-market adjustment of $277,000, net of tax at April 3,
2010, compared to a pension liability adjustment of $3,146,000, net of tax, and an interest rate hedge mark-to-market adjustment of $408,000, net of tax, at December 31, 2009.

Recent Accounting Pronouncements

There were no recent accounting pronouncements affecting the Company.

Use of Estimates

Certain amounts and disclosures included in the consolidated financial statements required management to make estimates and judgments that
affect the amounts of assets, liabilities, revenues and expenses, and related disclosures of contingent assets and liabilities. These estimates are based on historical experience and on various other assumptions that are believed to be reasonable
under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates.

Reclassifications

Certain prior period information has been reclassified to conform to the current period presentation.

At April 3, 2010, the Company had $92,950,000 of
unused lines of credit, after deducting $850,000 for outstanding standby letters of credit. The Company had outstanding loans of $26,200,000 and was in compliance with all covenants at April 3, 2010. The weighted average interest rate on
borrowings outstanding was 5.94% at April 3, 2010, compared to 4.50% at April 4, 2009. The carrying amount of long-term debt approximates fair value based on the terms of the related debt, recent transactions and estimates using interest
rates currently available to the Company for debt with similar terms and remaining maturities.

Note 4. Shareholders Equity

At April 3, 2010, $2,773,030 remained available to repurchase common stock of the Company under stock repurchase
programs as previously approved by the Board of Directors. The Company repurchased in the open market 0 and 80,576 shares for $1,042,000 of its common stock during the first quarters of 2010 and 2009, respectively.

Note 5. Employee Benefit Plans

The Company has a defined benefit pension plan covering certain hourly employees of a subsidiary. Pension plan benefits are generally
determined on the basis of the retirees age and length of service. Assets of the defined benefit pension plan are composed primarily of fixed income and equity securities.

Note 6. Indemnifications

The Company has made guarantees and indemnities under which it may be required to make payments to a guaranteed or indemnified party, in
relation to certain transactions, including revenue transactions in the ordinary course of business. In connection with certain facility leases the Company has indemnified its lessors for certain claims arising from the facility or the lease. The
Company indemnifies its directors and officers to the maximum extent permitted under the laws of the State of Delaware. However, the Company has a directors and officers insurance policy that may reduce its exposure in certain circumstances and may
enable it to recover a portion of future amounts that may be payable, if any. The duration of the guarantees and indemnities varies and, in many cases is indefinite but subject to statute of limitations. The majority of guarantees and indemnities do
not provide any limitations of the maximum potential future payments the Company could be obligated to make. Historically, payments related to these guarantees and indemnities have been immaterial. The Company estimates the fair value of its
indemnification obligations as insignificant based on this history and insurance coverage and has, therefore, not recorded any liability for these guarantees and indemnities in the accompanying consolidated balance sheets. However, there can be no
assurances that the Company will not have any future financial exposure under these indemnification obligations.

Note 7. Income Taxes

The Company records the interest charge and penalty charge, if any, with respect to uncertain tax positions as a component of
tax expense. During the three months ended April 3, 2010 and April 4, 2009, the Company recognized approximately $34,000 and $24,000, respectively, in interest related to uncertain tax positions. The Company had approximately $337,000 and
$303,000 for the payment of interest and penalties accrued at April 3, 2010 and December 31, 2009, respectively.

The Companys total amount of unrecognized tax benefits was approximately $2,648,000 and $2,161,000 at April 3, 2010 and
December 31, 2009, respectively. These amounts, if recognized, would affect the income tax rate.

The Companys California franchise (income) tax returns for 2004 and 2005 have been
selected for examination. The Company does not expect the results of this examination to have a material impact on the Companys financial statements. Federal income tax returns after 2006, California franchise (income) tax returns after 2005
and other state income tax returns after 2005 are subject to examination.

Note 8. Contingencies

The Company is a defendant in a lawsuit entitled United States of America ex rel Taylor Smith, Jeannine Prewitt and James Ailes v. The
Boeing Company and Ducommun Inc., filed in the United States District Court for the District of Kansas (the District Court). The lawsuit is a qui tam action brought against The Boeing Company (Boeing) and
Ducommun on behalf of the United States of America for violations of the United States False Claims Act. The lawsuit alleges that Ducommun sold unapproved parts to the Boeing Commercial Airplanes-Wichita Division which were installed by Boeing in
aircraft ultimately sold to the United States government. The number of Boeing aircraft subject to the lawsuit has been reduced to 25 aircraft following the District Courts granting of partial summary judgment in favor of Boeing and Ducommun.
The lawsuit seeks damages, civil penalties and other relief from the defendants for presenting or causing to be presented false claims for payment to the United States government. Although the amount of alleged damages are not specified, the lawsuit
seeks damages in an amount equal to three times the amount of damages the United States government sustained because of the defendants actions, plus a civil penalty of $10,000 for each false claim made on or before September 28, 1999, and
$11,000 for each false claim made on or after September 28, 1999, together with attorneys fees and costs. The Company intends to defend itself vigorously against the lawsuit. The Company, at this time, is unable to estimate what, if any,
liability it may have in connection with the lawsuit.

DAS has been directed by California environmental agencies to
investigate and take corrective action for ground water contamination at its facilities located in El Mirage and Monrovia, California. Based on currently available information, the Company has established a reserve for its estimated liability for
such investigation and corrective action in the approximate amount of $1,247,000. DAS also faces liability as a potentially responsible party for hazardous waste disposed at two landfills located in Casmalia and West Covina, California. DAS and
other companies and government entities have entered into consent decrees with respect to each landfill with the United States Environmental Protection Agency and/or California environmental agencies under which certain investigation, remediation
and maintenance activities are being performed. Based upon currently available information, the Company has established a reserve for its estimated liability in connection with the landfills in the approximate amount of $1,074,000. The
Companys ultimate liability in connection with these matters will depend upon a number of factors, including changes in existing laws and regulations, the design and cost of construction, operation and maintenance activities, and the
allocation of liability among potentially responsible parties.

In the normal course of business, Ducommun and its subsidiaries are defendants in
certain other litigation, claims and inquiries, including matters relating to environmental laws. In addition, the Company makes various commitments and incurs contingent liabilities. While it is not feasible to predict the outcome of these matters,
the Company does not presently expect that any sum it may be required to pay in connection with these matters would have a material adverse effect on its consolidated financial position, results of operations or cash flows.

Note 9. Business Segment Information

The Company supplies products and services to the aerospace industry. The Companys subsidiaries are organized into two strategic
businesses, each of which is a reportable operating segment. The accounting policies of the segments are the same as those of the Company. Ducommun AeroStructures, Inc. (DAS), engineers and manufactures aerospace structural components
and subassemblies. Ducommun Technologies, Inc. (DTI), designs, engineers and manufactures electromechanical components and subsystems, and provides engineering, technical and program management services (including design, development,
integration and test of prototype products) principally for the aerospace and military markets.

The Companys mix of military, commercial and space business in the first quarters of
2010 and 2009, respectively, was approximately as follows:



|                               |  |               |   |  |      |

Sales for the first quarter of 2010 decreased 6% to $104,256,000 as compared to $111,355,000 for the first
quarter of 2009. The 6% decrease in sales for the first quarter of 2010 was due to lower period-over-period sales for the Apache helicopter and regional and business aircraft, and lower revenues from engineering services, partially offset by growth
in sales for large commercial and military aircraft and commercial helicopter programs.

Operating income for the first
quarter of 2010 increased 52% from the first quarter of 2009. Operating income for the first quarter of 2009 was negatively impacted by an inventory reserve of $4,359,000 related to the Eclipse Aviation Corporation bankruptcy filing in March 2009.
Operating income for the first quarter of 2010 was favorably impacted by lower selling, general and administrative expenses due to lower people related expenses and cost controls. Operating income for the first quarter of 2010 was negatively
impacted by $1,800,000 due to start-up cost of several new production and product development programs which generated approximately $3,100,000 in sales. Operating income was also negatively impacted by lower operating income from Ducommun
Technologies, Inc. (DTI) primarily due to lower sales, including lower than anticipated sales of military and commercial spares and changes in product mix during the first quarter of 2010.

Results of Operations

First Quarter of 2010 Compared to First Quarter of 2009

Net sales in the first quarter of 2010 were $104,256,000, compared to net sales in the first quarter 2009 of $111,355,000. Net sales in
the first quarter of 2010 decreased 6% from the same period last year primarily due to lower sales for the Apache helicopter and regional and business aircraft, and lower revenues from engineering services, partially offset by growth in sales for
large commercial and military aircraft and commercial helicopter programs. The Companys mix of business in the first quarter of 2010 was approximately 58% military, 40% commercial, and 2% space, compared to 61% military, 37% commercial, and 2%
space in the first quarter of 2009.

The Company had substantial sales, through both of its business segments, to Boeing,
Raytheon, the United States government and United Technologies. During the first quarters of 2010 and 2009, sales to these customers were as follows:



|                         |  |                    |        |              |   |

At April 3, 2010, trade receivables from Boeing,
Raytheon, United Technologies and the United States government were $9,260,000, $5,378,000, $4,308,000 and $1,862,000, respectively. The sales and receivables relating to Boeing, Raytheon, the United States government and United Technologies are
diversified over a number of different commercial, space and military programs.

Military components manufactured by the
Company are employed in many of the countrys front-line fighters, bombers, helicopters and support aircraft, as well as sea-based applications. Engineering, technical and program management services are provided principally for United States
defense, space and homeland security programs. The Companys defense business is diversified among military manufacturers and programs. Sales related to military programs were approximately $60,908,000, or 58% of total sales, in the first
quarter of 2010, compared to $67,943,000, or 61% of total sales, in the first quarter of 2009. The decrease in military sales in the first quarter of 2010 resulted principally from a decreases in sales to the Apache helicopter and Chinook helicopter
programs at DAS and lower revenues from engineering services at DTI, partially offset by increases in sales to the F-18 and F-15 aircraft programs at DTI and the C-17 and Blackhawk programs mainly at DAS.

|Total     |  | $                  | 40,796 |              | $ | 43,821

The Companys commercial business is represented
on many of todays major commercial aircraft. Sales related to commercial business were approximately $41,628,000, or 40% of total sales, in the first quarter 2010, compared to $41,243,000, or 37% of total sales, in the first quarter 2009. The
increase in commercial sales in the first quarter of 2010 resulted principally from growth in sales for large commercial aircraft and commercial helicopter programs, partially offset by a decline in sales for regional and business aircraft. Sales to
the Boeing 737NG program accounted for approximately $10,908,000 in sales in the first quarter 2010, compared to $10,103,000 in sales in the first quarter 2009.

In the space sector, the Company produces components for a variety of unmanned launch vehicles and satellite programs and provides
engineering services. Sales related to space programs were approximately $1,720,000, or 2% of total sales in the first quarter of 2010, compared to $2,169,000, or 2% of total sales in the first quarter of 2009. The decrease in sales for space
programs resulted principally from a decrease in engineering services at DTI.

Backlog is subject to delivery delays or
program cancellations, which are beyond the Companys control. As of April 3, 2010, backlog believed to be firm was approximately $332,051,000, compared to $367,183,000 at December 31, 2009. The reduction in backlog is reflective of
(i) slower than anticipated order releases from the regional and business aircraft customers due primarily to the changing market demand in 2009, (ii) planned reductions in the Apache helicopter program, (iii) late order release on
the F-18 programs, and (iv) declines in the engineering services business resulting from lower RDT&E budgets, reduced demand for specific engineering services as a result of increases in government in-sourcing and

reduced Congressional earmarks. Approximately $200,000,000 of total backlog is expected to be delivered during 2010. The backlog at April 3, 2010 included the following programs:

Trends in the Companys overall level of backlog,
however, may not be indicative of trends in future sales because the Companys backlog is affected by timing differences in the placement of customer orders and because the Companys backlog tends to be concentrated in several programs to
a greater extent than the Companys sales.

Gross profit, as a percent of sales, increased to 18.5% in the first quarter
of 2010, compared to 15.5% in the first quarter 2009. Gross profit for the first quarter of 2009 was negatively impacted by an inventory reserve of $4,359,000 related to the Eclipse Aviation Corporation bankruptcy filing in March 2009. Gross profit
margin was negatively impacted in the first quarter of 2010 by $1,800,000 due to start-up costs of several new production and product development programs which generated approximately $3,100,000 in sales. Gross profit margins in the first quarter
of 2010 were also impacted by lower sales volume and an unfavorable change in sales mix at DTI.

Selling, general and
administrative (SG&A) expenses decreased to $12,463,000, or 12.0% of sales, in the first quarter 2010, compared to $12,809,000, or 11.5% of sales, in the first quarter 2009. The decrease in SG&A expenses was primarily due to a
reduction in people related expenses and cost controls, partially offset by a $606,000 increase in expenses related to amortization of intangible assets.

Interest expense was $552,000 in the first quarter 2010, compared to $639,000 in the first quarter 2009, primarily due to lower debt
levels, partially offset by higher interest rates in the first quarter of 2010 compared to the first quarter of 2009.

Income tax expense increased to $2,080,000 in the first quarter 2010, compared to $1,273,000
in the first quarter 2009. The increase in income tax expense was due to the increase in income before taxes, with an effective tax rate of 33.0% for both periods.

Financial Condition

Cash Flow Summary

Net cash used in operating activities for the first three months of 2010 and 2009 was $20,954,000 and $23,446,000, respectively. Net cash
used in operating activities for the first three months of 2010 was impacted by an increase in accounts and unbilled receivables of $9,181,000 primarily related to the timing of billings to customers and extension of payments by the customers, a
reduction in accrued and other liabilities of $10,380,000 (consisting primarily of a $6,582,000 decrease in accrued bonuses, a $3,182,000 reduction in customer deposits and $616,000 reduction in other accrued liabilities), a decrease in accounts
payable of $5,390,000 and an increase in inventory of $4,111,000 primarily related to raw material and work-in-process for production jobs scheduled to be shipped in 2010 and 2011.

Net cash used in investing activities for the first three months of 2010 consisted primarily of $1,459,000 of capital expenditures.

Net cash provided by financing activities for the first three months of 2010 of $5,281,000 included approximately $6,186,000
of borrowings, $785,000 of dividends payments and $129,000 of cash payments related to the exercise of stock options.

Liquidity and Capital Resources

At April 3, 2010, the Company had $92,950,000 of unused lines of credit, after deducting $850,000 for outstanding standby letters of
credit. The Company had outstanding loans of $26,200,000 and was in compliance with all covenants at April 3, 2010.

The
Company continues to depend on operating cash flow and the availability of its bank line of credit to provide short-term liquidity. Cash from operations and bank borrowing capacity are expected to provide sufficient liquidity to meet the
Companys obligations during the next twelve months.

In connection with the DAS-New York acquisition in December 2008,
the Company issued a promissory note in the initial principal amount of $7,000,000 with interest of five percent (5%) per annum payable annually on each anniversary of the closing date (December 23). Principal of the promissory note is payable
in the amount of $4,000,000 on June 23, 2010 and $3,000,000 on December 23, 2013.

The weighted average interest
rate on borrowings outstanding was 5.94% at April 3, 2010, compared to 4.50% at April 4, 2009. The carrying amount of long-term debt approximates fair value based on the terms of the related debt, recent transactions and estimates using
interest rates currently available to the Company for debt with similar terms and remaining maturities.

##### Table of Contents

The Company expects to spend approximately $11,000,000 for capital expenditures in 2010. The
increase in capital expenditures in 2010 from 2009 is principally to support new contract awards at DAS and DTI. The Company believes the ongoing subcontractor consolidation makes acquisitions an increasingly important component of the
Companys future growth. The Company plans to continue to seek attractive acquisition opportunities and to make substantial capital expenditures for manufacturing equipment and facilities to support long-term contracts for both commercial and
military aircraft programs.

The Company spent approximately $2,058,000 for tooling related investment on various sales
programs in 2010. As part of the Companys strategic direction in moving to a Tier 2 supplier additional up front investment in tooling will be required for newer programs which have higher engineering content and higher levels of complexity in
assemblies.

Dividends are subject to the approval of the Board of Directors, and will depend upon the Companys results
of operations, cash flows and financial position. The Company expects to continue to pay dividends of $0.075 per quarter per common share in 2010.

The Company has made guarantees and indemnities under which it may be required to make payments to a guaranteed or indemnified party, in
relation to certain transactions, including revenue transactions in the ordinary course of business. In connection with certain facility leases, the Company has indemnified its lessors for certain claims arising from the facility or the lease. The
Company indemnifies its directors and officers to the maximum extent permitted under the laws of the State of Delaware. However, the Company has a directors and officers insurance policy that may reduce its exposure in certain circumstances and may
enable it to recover a portion of future amounts that may be payable, if any. The duration of the guarantees and indemnities varies and, in many cases, is indefinite but subject to statute of limitations. The majority of guarantees and indemnities
do not provide any limitations of the maximum potential future payments the Company could be obligated to make. Historically, payments related to these guarantees and indemnities have been immaterial. The Company estimates the fair value of its
indemnification obligations as insignificant based on this history and insurance coverage and has, therefore, not recorded any liability for these guarantees and indemnities in the accompanying consolidated balance sheets. However, there can be no
assurances that the Company will not have any future financial exposure under these indemnification obligations.

The Company is a defendant in a lawsuit entitled
United States of America ex rel Taylor Smith, Jeannine Prewitt and James Ailes v. The Boeing Company and Ducommun Inc., filed in the United States District Court for the District of Kansas (the District Court). The lawsuit is a
qui tam action brought against The Boeing Company (Boeing) and Ducommun on behalf of the United States of America for violations of the United States False Claims Act. The lawsuit alleges that Ducommun sold unapproved parts to the
Boeing Commercial Airplanes-Wichita Division which were installed by Boeing in aircraft ultimately sold to the United States government. The number of Boeing aircraft subject to the lawsuit has been reduced to 25 aircraft following the District
Courts granting of partial summary judgment in favor of Boeing and Ducommun. The lawsuit seeks damages, civil penalties and other relief from the defendants for presenting or causing to be presented false claims for payment to the United
States government. Although the amount of alleged damages are not specified, the lawsuit seeks damages in an amount equal to three times the amount of damages the United States government sustained because of the defendants actions, plus a
civil penalty of $10,000 for each false claim made on or before September 28, 1999, and $11,000 for each false claim made on or after September 28, 1999, together with attorneys fees and costs. The Company intends to defend itself
vigorously against the lawsuit. The Company, at this time, is unable to estimate what, if any, liability it may have in connection with the lawsuit.

DAS has been directed by California environmental agencies to investigate and take corrective action for ground water contamination at
its facilities located in El Mirage and Monrovia, California. Based on currently available information, the Company has established a reserve for its estimated liability for such investigation and corrective action in the approximate amount of
$1,247,000. DAS also faces liability as a potentially responsible party for hazardous waste disposed at two landfills located in Casmalia and West Covina, California. DAS and other companies and government entities have entered into consent decrees
with respect to each landfill with the United States Environmental Protection Agency and/or California environmental agencies under which certain investigation, remediation and maintenance activities are being performed. Based upon currently
available information, the Company has established a reserve for its estimated liability in connection with the landfills in the approximate amount of $1,074,000. The Companys ultimate liability in connection with these matters will depend
upon a number of factors, including changes in existing laws and regulations, the design and cost of construction, operation and maintenance activities, and the allocation of liability among potentially responsible parties.

other litigation, claims and inquiries, including matters relating to environmental laws. In addition, the Company makes various commitments and incurs contingent liabilities. While it is not feasible to predict the outcome of these matters, the
Company does not presently expect that any sum it may be required to pay in connection with these matters would have a material adverse effect on its consolidated financial position, results of operations or cash flows.
