WOODWARD
Notes to Consolidated Financial Statements

(1) Overview:

The consolidated balance sheet as of December 31, 2006, the consolidated statements of earnings for the three-month periods ended December 31, 2006 and 2005, and the consolidated statements of cash flows for the three-month periods ended December 31, 2006 and 2005, were prepared by the company without audit. The September 30, 2006, consolidated balance sheet was derived from audited financial statements, but does not include all disclosures required by generally accepted accounting principles. Information in this 10-Q report is based in part on estimates and is subject to year-end adjustments and audit. In our opinion, the figures reflect all adjustments necessary to present fairly the company’s financial position as of December 31, 2006, the results of its operations for the three-month periods ended December 31, 2006 and 2005, and its cash flows for the three-month periods ended December 31, 2006 and 2005. All such adjustments were of a normal and recurring nature. The statements were prepared following the accounting policies described in the company’s 2006 annual report on Form 10-K and should be read with the notes to consolidated financial statements in the annual report. The consolidated statement of earnings for the three-month period ended December 31, 2006, is not necessarily indicative of the results to be expected for other interim periods or for the full year.

(2) Earnings per share:

(In thousands except per	Three months ended December 31,
share amounts)	2006		2005
Net earnings(A)	$	17,887	$	12,427
Determination of shares:
Weighted-average shares of common stock outstanding excluding shares held for deferred compensation obligations		33,697		33,933
Weighted-average shares of common stock outstanding held for deferred compensation obligations		415		414
Total weighted-average shares of common stock outstanding (B)		34,112		34,347
Assumed exercise of stock options		927		825
Weighted-average shares of common stock outstanding assuming dilution (C)		35,039		35,172
Net earnings:
Basic per share amount (A/B)	$	0.52	$	0.36
Diluted per share amount (A/C)		0.51		0.35

We excluded stock options for 189,566 shares for the three months ended December 31, 2006, and 541,311 shares for the three months ended December 31, 2005, from the calculation of diluted net earnings per share because their inclusion would have been anti-dilutive.

(3) Business acquisition:

On October 31, 2006, we acquired 100 percent of the stock of SEG Schaltanlagen-Elektronick-Geräte GmbH & Co. KG (SEG) and a related receivable from SEG that was held by one of the sellers. The acquisition provides us with technologies and products that complement our power generation system solutions. Headquartered in Kempen, Germany, SEG is focused on the design and manufacture of a wide range of protection and comprehensive control systems for power generation and distribution applications, power inverters for wind turbines, and complete electrical systems for gas and diesel engine based power stations.

The cost for the acquisition of SEG totaled $44,882,000, consisting of $34,564,000 of cash and $10,318,000 of assumed debt obligations. Of this amount, $23,203,000 was recognized as goodwill. However, the cost of the acquisition and the related allocation of the acquisition cost are subject to change. The cost of the acquisition may increase or decrease based on the final determination of the direct acquisition costs. Also, we are in the process of finalizing valuations of property, plant, and equipment, other intangibles, and estimates of liabilities associated with the acquisition. We currently expect to finalize the cost of the acquisition and the related allocation of the acquisition cost before the end of June 2007.

The results of SEG’s operations are included in our consolidated statements of earnings from the beginning of November 2006. If we had completed the acquisition on October 1, 2005, our net sales and net earnings for the three months ended December 31, 2006 and 2005 would not have been materially different from amounts reported in the statements of consolidated earnings.

(4) Income taxes:

Income taxes for the three months ended December 31, 2006, includes an expense reduction of $1,177,000 related to the retroactive extension of the U.S. research and experimentation tax credit. This expense reduction relates to the estimated amount of the credit applicable to the period January 1, 2006 through September 30, 2006.

The contractual termination benefits reflect an increase in our pension obligations for certain participants as a result of workforce management actions. The settlement gains reflect settlements with certain participants that relieved us of obligations for future retirement healthcare payments.

We are entitled to a federal subsidy under the Medicare Prescription Drug, Improvement and Modernization Act of 2003. We received $433,000 for the three months ended December 31, 2006,

and we currently expect to receive an additional $446,000 during the year ending September 30, 2007. In the three months ended December 31, 2006, we paid $678,000 for prescription drug benefits and expect to pay additional prescription drug benefits of approximately $1,570,000 for the year ending September 30, 2007.

(14) Contingencies:

We are currently involved in pending or threatened litigation or other legal proceedings regarding employment, product liability, and contractual matters arising from the normal course of business. We accrue for individual matters that we believe are likely to result in a loss when ultimately resolved using estimates of the most likely amount of loss, including $8,500,000 accrued for a specific matter in 2006. There are also individual matters that we believe the likelihood of a loss when ultimately resolved is less than likely but more than remote, which were not accrued. While it is possible that there could be additional losses that have not been accrued, we currently believe the possible additional loss in the event of an unfavorable resolution of each matter is less than $10,000,000 in the aggregate.

Among the legal proceedings referred to in the preceding paragraph, we were a defendant in a class action lawsuit filed in the U.S. District Court for Northern District of Illinois and received findings of the U.S. Equal Employment Opportunity Commission that alleged discrimination on the basis of race, national origin, and gender in our Winnebago County, Illinois, facilities. On October 5, 2006, a U.S. District Court Judge gave preliminary approval to a proposed $5,000,000 settlement of the class action and EEOC matters. Accruals for the amount of the settlement and related legal expenses are included in our consolidated balance sheet at December 31, 2006. Also, cash balances that were restricted for settlements have been reported as other current assets at December 31, 2006.

We file income tax returns in various jurisdictions worldwide, which are subject to audit. We have accrued for our estimate of the most likely amount of expenses that we believe will result from income tax audit adjustments.

We do not recognize contingencies that might result in a gain until such contingencies are resolved and the related amounts are realized.

In the event of a change in control of the company, we may be

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

We prepared the following discussion and analysis to help you better understand our financial condition, changes in our financial condition, and results of operations. This discussion should be read with the consolidated financial statements.

Overview

Woodward designs, manufactures, and services energy control systems and components for aircraft and industrial engines and turbines. Leading OEMs throughout the world use our products and services in the power generation, process industries, transportation, and aerospace markets.

Our strategic focus is Energy Control and Optimization Solutions. The control of energy — fluid energy, combustion, electrical energy, and motion — is a growing requirement in the markets we serve. Our customers look to us to optimize the efficiency, emissions, and operations of power equipment. Our core technologies leverage well across our markets and customer applications, enabling us to develop and integrate cost-effective and state-of-the-art fuel, combustion, fluid, actuation, and electronic systems. We focus primarily on OEMs and equipment packagers, partnering with them to bring superior component and system solutions to their demanding applications.

We have two operating segments — Industrial Controls and Aircraft Engine Systems. Industrial Controls is focused on systems and components that provide energy control and optimization solutions for industrial markets, which includes power generation, transportation, and process industries. Aircraft Engine Systems is focused on systems and components that provide energy control and optimization solutions for the aerospace market. We use segment information internally to assess the performance of each segment and to make decisions on the allocation of resources.

Industrial Controls’ segment earnings increased to 12.8% of sales from 9.3% of sales a year ago on a sales increase of 20%. Approximately half of the sales increase was related to the inclusion of sales from SEG, a business acquired at the end of October 2006. The earnings improvement reflected the effects of the higher sales volume, leverage of fixed costs and expenses over the higher sales, and reductions in certain expenses due to actions taken over the last two years, including the consolidation of our European facilities.

Aircraft Engine Systems’ first quarter earnings increased 15% on a sales increase of 9% from the first quarter a year ago. Its earnings continued to exceed 20% of sales.

Our first quarter results this year also included the effect of the retroactive extension of the U.S. research and experimentation tax credit, which improved net earnings by $1.2 million, or $0.03 per diluted share.

14

At December 31, 2006, our total assets were $764 million, including $43 million in cash, and our total debt was $72 million. We are well positioned to fund expanded research and development and to explore other investment opportunities consistent with our focused strategies.

In the sections that follow, we are providing information to help you better understand our critical accounting policies and market risks, our results of operations and financial condition, and the effects of recent accounting pronouncements. However, you should be aware that this discussion contains statements intended to be considered forward-looking statements and therefore entitled to the safe harbor provision of the Private Securities Litigation Reform Act of 1995. Information about forward-looking statements, including important factors that could affect our business, results of operations and/or financial condition, are referred to in “Part II — Item 1A — Risk Factors.”

Critical Accounting Policies

We consider the accounting policies used in preparing our financial statements to be critical accounting policies when they are both important to the portrayal of our financial condition and results of operations, and require us to make difficult, subjective, or complex judgments. Critical accounting policies normally result from the need to make estimates about the effect of matters that are inherently uncertain. Management has discussed the development and selection of our critical accounting policies with the audit committee of the company’s Board of Directors. In each of the areas that were identified as critical accounting policies, our judgments, estimates, and assumptions are impacted by conditions that change over time. As a result, in the future there could be changes in our assets and liabilities, increases or decreases in our expenses, and additional losses or gains that are material to our financial condition and results of operations. Our critical accounting policies are discussed more fully in the management discussion and analysis in our annual report on Form 10-K for the year ended September 30, 2006.

Market Risks

Our long-term debt is sensitive to changes in interest rates. Also, assets, liabilities, and commitments that are to be settled in cash and are denominated in foreign currencies for transaction purposes are sensitive to changes in currency exchange rates. These market risks are discussed more fully in the management discussion and analysis in our annual report on Form 10-K for the year ended September 30, 2006.

Results of Operations

Sales

15

	Three months
	ended
	December 31,
(In thousands)	2006		2005
External net sales:
Industrial Controls	$	148,826	$	124,459
Aircraft Engine Systems		77,422		71,175
Consolidated net sales	$	226,248	$	195,634

Industrial Controls’ external net sales increased in the three months ended December 31, 2006, over the same period a year ago. This year’s sales include the external net sales of an acquired business beginning from its acquisition date of October 31, 2006, of $13.8 million. The remaining increase primarily reflects higher sales of large turbine and diesel fuel systems products due to increased demand in the power generation and marine markets.

Aircraft Engine Systems’ external net sales increased in the three months ended December 31, 2006, over the same period a year ago. The increase was related to higher production levels of aircraft engines by our customers to support the requirements of Boeing, Airbus, and other airframe manufacturers. In addition, aircraft usage has increased, as driven by higher revenue passenger miles by commercial airlines and cargo growth, which has positively affected our aftermarket sales.

Costs and Expenses

	Three months
	ended December 31,
(In thousands)	2006			2005
Cost of goods sold	$	157,744		$	141,939
Sales, general, and administrative expenses		26,380			21,057
Research and development costs		13,954			11,910
All other expense items		3,121			3,280
Interest and other income		(1,603	)		(1,671	)
Consolidated costs and expenses	$	199,596		$	176,515

Cost of goods sold increased in the three months ended December 31, 2006, compared to the same period last year, primarily as a result of the following (in millions):

•       Increase in sales volume	$	22
•       Lower overhead costs as percent of sales		(4	)
•       Other factors, net		(2	)

The effect of the increased sales volume on cost of goods sold was measured as if these costs increased in direct proportion to the sales volume increase.

The overhead costs improvement reflected the favorable operating leverage of fixed overhead against higher sales

16

volumes in both segments. In addition, there were reductions in certain fixed costs, primarily in Industrial Controls. Industrial Controls benefited from the effects of a European consolidation that we completed in March 2006.

Gross margins (as measured by external net sales less external cost of goods sold) increased from 27.4% of sales in the first quarter of 2006 to 30.3% of sales in the first quarter of 2007.

Sales, general, and administrative expenses increased in the three months ended December 31, 2006, as compared to the same period last year. The increase is primarily due to inclusion of the operating results of a business acquired on October 31, 2006, for November and December, and higher professional fees and costs associated with business development activities.

Research and development costs increased in three months ended December 31, 2006, as compared to the same period last year reflecting higher levels of development activity.

In Industrial Controls, we are working closely with our customers early in their own development and design stages, helping them by developing components and integrated systems that allow them to meet emissions requirements, increase fuel efficiency, and lower their costs. We also continue to develop products for the turbine auxiliary market. Turbine auxiliary applications offer multiple opportunities to leverage our existing hydraulic and electric actuation and valve technologies for off-engine applications.

Aircraft Engine Systems is developing new aircraft gas turbine programs for both commercial and military aircraft. Most significantly we are developing components and an integrated fuel system for the new GEnx turbofan engine for the Boeing 787, Airbus A350, and Boeing 747-8, and components for the GE Rolls-Royce F136 and Pratt & Whitney F135 engines that are the two propulsion choices to power Lockheed’s Joint Strike Fighter aircraft, and components for the T700-GE-701D engine that will be used to upgrade the Sikorsky Black Hawk and Boeing Apache helicopters, among others.

Industrial Controls’ segment earnings increased in the three months ended December 31, 2006, as compared to the same period last year attributable to the following (in millions):

•       Increase in sales volume	$	6
•       Improved gross margins as percent of sales		6
•       Operating expenses of acquired business		(3	)
•       Other factors, net		(1	)

The effect of the increase in sales volume on Industrial Controls’ segment earnings was measured as if gross margins had increased in direct proportion to the sales volume increase without other changes.

Industrial Controls had a higher gross margin as a percent of sales in the first three months this year as compared to a year ago, which reflected the favorable operating leverage of fixed overhead against higher sales volumes. In addition, there were reductions in certain fixed costs, most significantly resulting from the effects of a European consolidation that we completed in March 2006.

Industrial Controls’ segment earnings include the results of a business we acquired on October 31, 2006 for November and December this year. The operating expenses of the acquired business reflected above are for selling, general, and administrative expenses and research and development costs.

On October 31, 2006, we acquired 100 percent of the stock of SEG Schaltanlagen-Elektronick-Geräte GmbH & Co. KG (SEG) and a related receivable from SEG that was held by one of the sellers. The acquisition provides us with technologies and products that complement our power generation system solutions. Headquartered in Kempen, Germany, SEG is focused on the design and manufacture of a wide range of protection and comprehensive control systems for power generation and distribution applications, power inverters for wind turbines, and complete electrical systems for gas and diesel engine based power stations.

The cost for the acquisition of SEG totaled $44.9 million, consisting of $34.6 million of cash and $10.3 million of assumed debt obligations. Of this amount, $23.2 million was recognized as goodwill. However, the cost of the acquisition and the related allocation of the acquisition cost are subject to change. The cost of the acquisition may increase or decrease based on the final determination of the direct acquisition costs. Also, we are in the process of finalizing valuations of property, plant, and equipment, other intangibles, and estimates of liabilities associated with the acquisition. We currently expect to finalize the cost of the acquisition and the related allocation of the acquisition cost before the end of June 2007.

18

Aircraft Engine Systems’ segment earnings increased in the three months ended December 31, 2006, as compared to the same period last year primarily as a result of an increase in sales volume.

Nonsegment expenses increased in the three months ended December 31, 2006, as compared to the same period a year ago, primarily as a result of higher professional fees and costs associated with business development activities.

Income taxes were provided at an effective rate on earnings before income taxes of 32.9% in the three-month period ended December 31, 2006, compared to 35.0% in the three-month period ended December 31, 2005.

During the quarter ended December 31, 2006, the U.S. research and experimentation credit was extended and made retroactive to January 1, 2006. As a result, we reflected the effect of the extension in our first quarter this year, which reduced our income tax expense by $1.2 million, or 4.4% of earnings before income taxes. This relates to the amount of the credit attributable for the period January 1, 2006 through September 30, 2006.

Among other changes in our effective tax rate are the effects of changes in the relative mix of earnings by tax jurisdiction, which affects the comparison of foreign and state income tax rates relative to the United States federal statutory rate.

Outlook: In November 2006, we provided guidance that we anticipated company-wide sales growth of 12% to 15% for 2007, including the effects of the SEG acquisition, and earnings of $2.05 to $2.15 per share. For Industrial Controls, we expected sales would grow 13% to 16% and generate segment earnings of 10% to 12% of sales. For Aircraft Engine Systems, we expected sales growth of 10% to 12% and segment earnings of 20% to 22% of sales. Our current expectations are consistent with our previous guidance, except that we now believe company-wide earnings and Industrial Controls’ earnings margin will be near the upper end of the ranges provided.

Financial Condition

Assets

	December 31,		September 30,
(In thousands)	2006		2006
Industrial Controls	$	427,097	$	360,577
Aircraft Engine Systems		227,480		229,269
Nonsegment assets		110,201		145,651
Consolidated total assets	$	764,778	$	735,497

Industrial Controls’ segment assets increased in the three months ended December 31, 2006, primarily as a result of the business acquisition on October 31, 2006.

Nonsegment assets decreased in the three months ended

19

December 31, 2006, primarily because of decreases in cash and cash equivalents. Changes in cash for the quarter are discussed more fully in a separate section of this management’s discussion and analysis.

Other Balance Sheet Measures

	December 31,		September 30,
(In thousands)	2006		2006
Working capital	$	232,538	$	260,243
Long-term debt, less current portion		49,075		58,739
Other liabilities		70,254		71,190
Shareholders’ equity		497,969		478,689

Working capital decreased during the three months ended December 31, 2006, primarily as a result of the use of cash to acquire a business on October 31, 2006. We used $34.6 million of cash for the acquisition (net of cash acquired), of which $4.0 million was allocated to net current liabilities and $38.6 million was allocated to net non-current assets. This working capital decrease was partially offset by the amount of working capital provided by operating activities, including cash of $13.8 million.

Long-term debt, less current portion decreased during the three months ended December 31, 2006, as a result of payments made during the quarter. The current portion of long-term debt remained approximately the same.

We currently have a revolving line of credit facility with a syndicate of U.S. banks totaling $100 million, with an option to increase the amount of the line to $175 million if we choose. The line of credit facility expires on March 11, 2010. In addition, we have other line of credit facilities, which totaled $17.7 million at September 30, 2006, that are generally reviewed annually for renewal. The total amount of borrowings under all facilities was $0.5 million at September 30, 2006.

Provisions of debt agreements include covenants customary to such agreements that require us to maintain specified minimum or maximum financial measures and place limitations on various investing and financing activities. The agreements also permit the lenders to accelerate repayment requirements in the event of a material adverse event. Our most restrictive covenants require us to maintain a minimum consolidated net worth, a maximum consolidated debt to consolidated operating cash flow, and a maximum consolidated debt to EBITDA, as defined in the agreements. We were in compliance with all covenants at December 31, 2006.

Commitments and contingencies at December 31, 2006, include various matters arising from the normal course of business. We are currently involved in pending or threatened litigation or other legal proceedings regarding employment, product

20

liability, and contractual matters arising from the normal course of business. We accrue for individual matters that we believe are likely to result in a loss when ultimately resolved using estimates of the most likely amount of loss, including $8,500,000 accrued for a specific matter in 2006. There are also individual matters that we believe the likelihood of a loss when ultimately resolved is less than likely but more than remote, which were not accrued. While it is possible that there could be additional losses that have not been accrued, we currently believe the possible additional loss in the event of an unfavorable resolution of each matter is less than $10,000,000 in the aggregate.

Among the legal proceedings referred to in the preceding paragraph, we were a defendant in a class action lawsuit filed in the U.S. District Court for Northern District of Illinois and received findings of the U.S. Equal Employment Opportunity Commission that alleged discrimination on the basis of race, national origin, and gender in our Winnebago County, Illinois, facilities. On October 5, 2006, a U.S. District Court Judge gave preliminary approval to a proposed $5,000,000 settlement of the class action and EEOC matters. Accruals for the amount of the settlement and related legal expenses are included in our consolidated balance sheet at December 31, 2006. Also, cash balances that were restricted for settlements have been reported as other current assets at December 31, 2006.

We file income tax returns in various jurisdictions worldwide, which are subject to audit. We have accrued for our estimate of the most likely amount of expenses that we believe will result from income tax audit adjustments.

We do not recognize contingencies that might result in a gain until such contingencies are resolved and the related amounts are realized.

In the event of a change in control of the company, we may be required to pay termination benefits to certain executive officers.

Shareholders’ equity increased in the three months ended December 31, 2006. Increases due to net earnings, foreign currency translation adjustments, sales of treasury stock, excess tax benefits from stock compensation, and stock compensation expense during the three months were partially offset by purchases of treasury stock and cash dividend payments.

On July 25, 2006, the Board of Directors authorized the repurchase of up to $50 million of our outstanding shares of common stock on the open market and private transactions over a three-year period that will end on July 25, 2009. Through December 31, 2006, we purchased $6.9 million of our common stock under this authorization.

Contractual Obligations

21

We have various contractual obligations, including obligations related to long-term debt, operating leases, purchases, retirement pensions, and retirement healthcare. These contractual obligations are summarized and discussed more fully in the management discussion and analysis in our 2006 annual report on Form 10-K for the year ended September 30, 2007.

Cash Flows

	Three months
	ended December 31,
(In thousands)	2006			2005
Net cash provided (used) by operating activities	$	13,754		$	(448	)
Net cash used in investing activities		(39,882	)		(4,749	)
Net cash used in financing activities		(15,096	)		(7,880	)

Net cash flows for operating activities increased by $14.2 million in the three months ended December 31, 2006, compared to the same period last year. Cash receipts from customers increased proportionately with the overall increase in sales for the three-month period compared to a year ago. Cash disbursements to employees and suppliers also increased for the three-month period, although at a lower rate than cash collected from customers. Higher variable compensation payments were made in the previous year (for amounts earned and accrued in fiscal year 2005) than were made this year.

Net cash flows used in investing activities increased by $35.1 million in the three months ended December 31, 2006, compared to the same period last year as a result of an October 31, 2006, business acquisition.

Net cash flows used in financing activities increased by $7.2 million in the three months ended December 31, 2006, compared to the same period last year primarily as a result of changes in borrowing activity. Net payments on borrowings totaled $12.3 million in this year’s first quarter compared to $4.6 million a year ago.

Outlook: Future cash flows from operations and available revolving lines of credit are expected to be adequate to meet our cash requirements over the next twelve months.

Payments of our senior notes, which totaled $53.6 million at December 31, 2006, are due over the 2008 — 2012 timeframe. Also, we have a $100 million line of credit facility that includes an option to increase the amount of the line up to $175 million that does not expire until March 11, 2010. Despite these factors, it is possible business acquisitions could be made in the future that would require amendments to existing debt agreements and the need to obtain additional financing.
