BASIS OF PRESENTATION
BASIS OF PRESENTATION	1. BASIS OF PRESENTATION The accompanying consolidated financial statements, in the opinion of management, include all adjustments, consisting of normal recurring accruals, necessary for a fair presentation of the results for the interim periods presented. The consolidated financial statements are presented in accordance with the requirements of Form 10-Q and consequently do not include all the disclosures required for annual financial statements by accounting principles generally accepted in the United States of America (GAAP). As a result of the pension plan termination referenced in the fourth quarter of 2020, certain prior year amounts have been reclassified to conform with the current year presentation. For further information, refer to the consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2020. The Company’s results for the three-month and nine-month periods ended June 30, 2021 are not necessarily indicative of the results for the entire 2021 fiscal year. References to the third quarters of 2021 and 2020 represent the fiscal quarters ended June 30, 2021 and 2020, respectively. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities. Actual results could differ from those estimates.

BUSINESS SEGMENT INFORMATION
BUSINESS SEGMENT INFORMATION	6. BUSINESS SEGMENT INFORMATION The Company is organized based on the products and services that it offers and classifies its continuing business operations in three reportable segments for financial reporting purposes: Aerospace & Defense, Utility Solutions Group (USG), and RF Shielding and Test (Test). The Aerospace & Defense segment’s operations consist of PTI Technologies Inc. (PTI), VACCO Industries (VACCO), Crissair, Inc. (Crissair), Westland Technologies Inc. (Westland), Mayday Manufacturing Co. and its affiliate Hi-Tech Metals, Inc. (collectively referred to as Mayday) and Globe Composite Solutions, LLC (Globe). The companies within this segment primarily design and manufacture specialty filtration, fluid control and naval products, including hydraulic filter elements and fluid control devices used in aerospace and defense applications; unique filter mechanisms used in micro-propulsion devices for satellites and custom designed filters for manned aircraft and submarines; products and systems to reduce vibration and/or acoustic signatures and otherwise reduce or obscure a vessel’s signature, and other communications, sealing, surface control and hydrodynamic related applications to enhance U.S. Navy maritime survivability; precision-tolerance machined components for the aerospace and defense industry; and metal processing services. The USG segment’s operations consist primarily of Doble Engineering Company and Morgan Schaffer Ltd. (together Doble), and NRG Systems, Inc. (NRG). Doble is an industry leader in the development, manufacture and delivery of diagnostic testing solutions that enable electric power grid operators to assess the integrity of high voltage power delivery equipment. NRG designs and manufactures decision support tools for the renewable energy industry, primarily wind and solar. The Test segment’s operations consist primarily of ETS-Lindgren Inc. (ETS-Lindgren). ETS-Lindgren is an industry leader in providing its customers with the ability to identify, measure and contain magnetic, electromagnetic and acoustic energy. ETS-Lindgren also manufactures radio frequency shielding products and components used by manufacturers of medical equipment, communications systems, electronic products, and shielded rooms for high-security data processing and secure communication. Management evaluates and measures the performance of its reportable segments based on “Net Sales” and “EBIT”, which are detailed in the table below. EBIT is defined as earnings from continuing operations before interest and taxes. The table below is presented on the basis of continuing operations and excludes discontinued operations. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months ​ Nine Months ​ ​ Ended June 30, ​ Ended June 30, (In thousands) 2021 2020 2021 2020 NET SALES ​ ​ ​ ​ ​ Aerospace & Defense ​ $ 85,576 ​ 84,072 ​ 234,720 ​ 256,707 USG ​ ​ 47,704 ​ 42,577 ​ 141,799 ​ 139,179 Test ​ ​ 48,114 ​ 46,016 ​ 133,443 ​ 128,999 Consolidated totals ​ $ 181,394 ​ 172,665 ​ 509,962 ​ 524,885 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ EBIT ​ ​ ​ ​ ​ ​ ​ ​ ​ Aerospace & Defense ​ $ 16,714 ​ 17,409 ​ 41,980 ​ 51,658 USG ​ ​ 8,227 ​ 6,156 ​ 27,683 ​ 20,310 Test ​ ​ 6,751 ​ 7,177 ​ 17,781 ​ 17,483 Corporate (loss) ​ ​ (12,269) ​ (7,410) ​ (30,359) ​ (27,983) Consolidated EBIT ​ ​ 19,423 ​ 23,332 ​ 57,085 ​ 61,468 Less: Interest expense ​ ​ (480) ​ (1,523) ​ (1,453) ​ (5,264) Earnings before income taxes ​ $ 18,943 ​ 21,809 ​ 55,632 ​ 56,204 ​ Non-GAAP Financial Measures The financial measure “EBIT” is presented in the above table and elsewhere in this Report. EBIT on a consolidated basis is a non-GAAP financial measure. Management believes that EBIT is useful in assessing the operational profitability of the Company’s business segments because it excludes interest and taxes, which are generally accounted for across the entire Company on a consolidated basis. EBIT is also one of the measures used by management in determining resource allocations within the Company as well as incentive compensation. A reconciliation of EBIT to net earnings from continuing operations is set forth in Item 2, Management’s Discussion and Analysis of Financial Condition and Results of Operations – EBIT. The Company believes that the presentation of EBIT provides important supplemental information to investors to facilitate comparisons with other companies, many of which use similar non-GAAP financial measures to supplement their GAAP results. However, the Company’s non-GAAP financial measures may not be comparable to other companies’ non-GAAP financial performance measures. Furthermore, the use of non-GAAP financial measures is not intended to replace any measures of performance determined in accordance with GAAP.

DEBT	7. DEBT The Company’s debt is summarized as follows: ​ ​ ​ ​ ​ ​ ​ ​ June 30, ​ September 30, (In thousands) 2021 2020 Total borrowings ​ $ 48,000 62,368 Current portion of long-term debt and short-term borrowings ​ (20,000) (22,368) Total long-term debt, less current portion ​ $ 28,000 40,000 ​ The Credit Facility includes a $500 million revolving line of credit as well as provisions allowing for the increase of the credit facility commitment amount by an additional $250 million, if necessary, with the consent of the lenders. The bank syndication supporting the facility is comprised of a diverse group of eight banks led by JP Morgan Chase Bank, N.A., as Administrative Agent. The Credit Facility matures September 27, 2024. At June 30, 2021, the Company had approximately $444 million available to borrow under the Credit Facility, plus the $250 million increase option, subject to lender approval, in addition to $78.4 million cash on hand. The Company classified $20.0 million as the current portion of long-term debt as of June 30, 2021, as the Company intends to repay this amount within the next twelve months; however, the Company has no contractual obligation to repay such amount during the next twelve months. The letters of credit issued and outstanding under the Credit Facility totaled $8.4 million at June 30, 2021. Interest on borrowings under the Credit Facility is calculated at a spread over either the London Interbank Offered Rate (LIBOR), the New York Federal Reserve Bank Rate or the prime rate, depending on various factors. The Credit Facility also requires a facility fee ranging from 10 to 25 basis points per annum on the unused portion. The Credit Facility is secured by the unlimited guaranty of the Company’s direct and indirect material U.S. subsidiaries and the pledge of 100% of the equity interests of its direct and indirect material foreign subsidiaries. The financial covenants of the Credit Facility include a leverage ratio and an interest coverage ratio. The weighted average interest rates were 1.16% and 1.33% for the three and nine- month periods ending June 30, 2021, respectively, and 3.24% and 3.22% for the three and nine-month periods ending June 30, 2020. As of June 30, 2021, the Company was in compliance with all covenants.

INCOME TAX EXPENSE
INCOME TAX EXPENSE	8. INCOME TAX EXPENSE The third quarter 2021 effective income tax rate was 21.3% compared to 14.3% in the third quarter of 2020. The effective income tax rate from continuing operations in the first nine months of 2021 was 22.5% compared to 15.9% in the first nine months of 2020. The income tax expense in the third quarter and first nine months of 2021 was favorably impacted by a tax return to provision true-up to foreign derived intangible income and other 2020 true-ups decreasing the third quarter and year-to-date effective tax rate by 3.9% and 1.2%, respectively. The income tax expense in the third quarter and first nine months of 2020 was favorably impacted mainly by the following items: 1) an increase in the available 2019 foreign tax credit which was attributable to new information and tax planning strategies reducing the third quarter effective tax rate and year-to-date effective tax rate by 3.3% and 1.3%; and 2) new information and tax planning strategies resulted in an increase in the 2020 foreign tax credit and the catch-up of the benefit which reduced the 2020 third quarter effective tax rate by 2.5%. The year-to-date 2020 effective tax rate was favorably impacted by the release of a valuation allowance of $2.8 million for foreign net operating losses decreasing the year-to-date 2020 effective tax rate by 5.1%.

FAIR VALUE MEASUREMENTS
FAIR VALUE MEASUREMENTS	10. FAIR VALUE MEASUREMENTS The accounting guidance establishes a three-level hierarchy for disclosure of fair value measurements, based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date, as follows: ● Level 1 – inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets. ● Level 2 – inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. ● Level 3 – inputs to the valuation methodology are unobservable and significant to the fair value measurement. Financial Assets and Liabilities The Company has estimated the fair value of its financial instruments as of June 30, 2021 and September 30, 2020 using available market information or other appropriate valuation methodologies. The carrying amounts of cash and cash equivalents, receivables, inventories, payables, debt and other current assets and liabilities approximate fair value because of the short maturity of those instruments. Fair Value of Financial Instruments The Company’s forward contracts and interest rate swaps are classified within Level 2 of the valuation hierarchy in accordance with FASB Accounting Standards Codification (ASC) 825, as presented below as of June 30, 2021: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (In thousands) Level 1 Level 2 ​ Level 3 Total Assets (Liabilities): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Forward contracts ​ $ — (27) $ — (27) ​ Valuation was based on third party evidence of similarly priced derivative instruments. Nonfinancial Assets and Liabilities The Company’s nonfinancial assets such as property, plant and equipment, and other intangible assets are not measured at fair value on a recurring basis; however they are subject to fair value adjustments in certain circumstances, such as when there is evidence that an impairment may exist. No impairments were recorded during the three and nine-month periods ended June 30, 2021.

LEASES

LEASES
LEASES	12. LEASES The Company determines at lease inception whether an arrangement that provides control over the use of an asset is a lease. The Company recognizes at lease commencement a right-of-use (ROU) asset and lease liability based on the present value of the future lease payments over the lease term. The Company has elected not to recognize a ROU asset and lease liability for leases with terms of 12 months or less. Certain of the Company’s leases include options to extend the term of the lease for up to 20 years. When it is reasonably certain that the Company will exercise the option, Management includes the impact of the option in the lease term for purposes of determining total future lease payments. As most of the Company’s lease agreements do not explicitly state the discount rate implicit in the lease, Management uses the Company’s incremental borrowing rate on the commencement date to calculate the present value of future payments based on the tenor of each arrangement. The Company’s leases for real estate commonly include escalating payments. These variable lease payments are included in the calculation of the ROU asset and lease liability. In addition to the present value of the future lease payments, the calculation of the ROU asset also includes any deferred rent, lease pre-payments and initial direct costs of obtaining the lease. In addition to the base rent, real estate leases typically contain provisions for common-area maintenance and other similar services, which are considered non-lease components for accounting purposes. Non-lease components are excluded from our ROU assets and lease liabilities and expensed as incurred. The Company’s leases are for office space, manufacturing facilities, and machinery and equipment. The components of lease costs are shown below: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Three Months Ended ​ ​ June 30, ​ June 30, (Dollars in thousands) 2021 2020 Finance lease cost ​ ​ ​ ​ Amortization of right-of-use assets ​ $ 492 ​ $ 540 Interest on lease liabilities ​ 306 ​ 319 Operating lease cost ​ 1,471 ​ 1,474 Total lease costs ​ $ 2,269 ​ $ 2,333 ​ ​ ​ ​ ​ ​ ​ ​ ​ Nine Months Nine Months ​ ​ Ended ​ Ended ​ ​ June 30, ​ June 30, (Dollars in thousands) 2021 2020 Finance lease cost ​ ​ ​ ​ ​ ​ Amortization of right-of-use assets ​ $ 1,477 ​ $ 1,622 Interest on lease liabilities ​ 929 ​ 970 Operating lease cost ​ 4,347 ​ 4,399 Total lease costs ​ $ 6,753 ​ $ 6,991 ​ Additional information related to leases are shown below: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Three Months Ended ​ ​ ​ June 30, ​ June 30, ​ (Dollars in thousands) 2021 2020 ​ Cash paid for amounts included in the measurement of lease liabilities ​ ​ ​ ​ ​ Operating cash flows from operating leases ​ $ 1,320 ​ $ 1,452 ​ Operating cash flows from finance leases ​ 306 ​ 319 ​ Financing cash flows from finance leases ​ 428 ​ 418 ​ Right-of-use assets obtained in exchange for operating lease liabilities ​ ​ 12,780 ​ ​ 53 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Nine Months Nine Months ​ ​ June 30, ​ June 30, (Dollars in thousands) 2021 2020 Cash paid for amounts included in the measurement of lease liabilities ​ ​ ​ ​ ​ ​ Operating cash flows from operating leases ​ $ 4,102 ​ $ 4,334 Operating cash flows from finance leases ​ 915 ​ 655 Financing cash flows from finance leases ​ 1,261 ​ 1,145 Right-of-use assets obtained in exchange for operating lease liabilities ​ ​ 12,780 ​ 22,072 ​ ​ ​ ​ ​ ​ ​ Weighted-average remaining lease term June 30, 2021 June 30, 2020 Operating leases 10.31 years 6.64 years ​ Finance leases 11.86 years 12.76 years ​ Weighted-average discount rate ​ Operating leases 3.12 % 3.14 % Finance leases 4.31 % 4.29 % ​ The following is a reconciliation of future undiscounted cash flows to the operating and finance lease liabilities, and the related ROU assets, presented on our Consolidated Balance Sheet on June 30, 2021: ​ ​ ​ ​ ​ ​ ​ ​ (Dollars in thousands) ​ Operating Finance Years Ending September 30: Leases Leases 2021 (excluding the nine months ended June 30, 2021) ​ $ 1,378 ​ 739 2022 ​ 5,093 ​ 3,015 2023 ​ 4,324 ​ 3,098 2024 ​ 3,677 ​ 3,181 2025 and thereafter ​ 21,976 ​ 28,285 Total minimum lease payments ​ 36,448 ​ 38,318 Less: amounts representing interest ​ 5,460 9,320 Present value of net minimum lease payments ​ $ 30,988 ​ 28,998 Less: current portion of lease obligations ​ 4,530 ​ 1,859 Non-current portion of lease obligations ​ ​ 26,458 ​ 27,139 ​ ​ ​ ​ ​ ​ ​ ROU assets ​ $ 30,426 ​ 24,689 ​ Operating lease liabilities are included in the Consolidated Balance Sheet in accrued other expenses (current portion) and as a caption on the Consolidated Balance Sheet (long-term portion).

ADJUSTED QUARTERLY FINANCIAL INFORMATION
ADJUSTED QUARTERLY FINANCIAL INFORMATION	13. ADJUSTED QUARTERLY FINANCIAL INFORMATION During the third quarter of 2021, the Company identified immaterial errors in the historical consolidated financial statements of Westland, within the A&D segment, and are being corrected as an immaterial revision of those financial statements. Specifically, the adjustments include $3.5 million related to net sales being overstated, of which $2.4 million related to the fourth quarter of 2020, $0.3 million related to the first quarter of 2021, and $0.8 million related to the second quarter of 2021. In addition, $2.1 million of the total adjustments resulted from inventory being overstated and cost of goods sold being understated, of which $0.9 million related to the fourth quarter of 2020, $0.8 million related to the first quarter of 2021, and $0.4 million related to the second quarter of 2021. The tax impact of correcting these errors was a reduction in tax expense of $0.8 million, $0.2 million, and $0.3 million in the fourth quarter of 2020, first quarter of 2021, and second quarter of 2021, respectively. This correction also resulted in a reclassification in the Consolidated Statements of Cash Flows between line items of net earnings, changes in assets and liabilities, and effect of deferred taxes totaling $3.3 million in the fourth quarter of 2020, $1.1 million in the first quarter of 2021, and $1.2 million in the second quarter of 2021, with no impact to the total net cash provided by operating activities for any period. The fiscal 2021 and 2020 quarterly results have been adjusted to reflect the correction of these adjustments in the proper periods. The table below shows the impact of all adjustments to the respective periods. Management has determined that all of these adjustments are not material to any prior periods or the current fiscal year. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ First Quarter ​ First Quarter ​ Second Quarter ​ Second Quarter (Dollars in thousands, except per share amounts) (As Reported) (As Adjusted) (As Reported) (As Adjusted) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 2021 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Net sales ​ $ 162,949 ​ 162,674 ​ 166,644 ​ 165,894 Cost of sales ​ ​ 98,777 ​ 99,622 ​ 103,113 ​ 103,553 Earnings before income taxes ​ ​ 17,660 ​ 16,540 ​ 21,339 ​ 20,149 Income tax expense ​ ​ 3,974 ​ 3,722 ​ 5,025 ​ 4,745 Net earnings ​ ​ 13,686 ​ 12,818 ​ 16,314 ​ 15,404 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Diluted earnings (loss) per share: ​ ​ ​ ​ ​ ​ ​ ​ ​ Net earnings ​ $ 0.52 ​ 0.49 ​ 0.62 ​ 0.59 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ First Quarter First Quarter Second Quarter Second Quarter ​ ​ (As Reported) ​ (As Adjusted) ​ (As Reported) ​ (As Adjusted) Contract assets ​ $ 93,762 91,043 95,002 91,533 Inventories ​ 144,054 142,316 145,342 143,164 Retained earnings ​ $ 790,000 786,563 804,231 799,884 ​ ​ ​ ​ ​ ​ ​ ​ Fourth Quarter Fourth Quarter (Dollars in thousands, except per share amounts) ​ (As Reported ​ (As Adjusted) ​ ​ ​ ​ ​ ​ 2020 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Net sales ​ $ 208,030 205,586 Cost of sales ​ 129,763 130,656 Loss before income taxes ​ (16,461) (19,798) Income tax expense ​ 5,347 4,579 Net loss ​ (21,808) (24,377) ​ ​ ​ ​ ​ ​ Diluted earnings (loss) per share: ​ Net loss ​ $ (0.83) (0.93) ​ ​ ​ ​ ​ ​ ​ ​ Fourth Quarter Fourth Quarter (Dollars in thousands, except per share amounts) ​ (As Reported ​ (As Adjusted) ​ ​ ​ ​ ​ ​ September 30, 2020 ​ ​ ​ ​ ​ ​ ​ ​ Contract assets ​ $ 96,746 94,302 Inventories ​ 136,189 135,296 Total current assets ​ 446,630 443,293 Total assets ​ 1,373,523 1,370,186 Total shareholders’ equity ​ 961,595 959,026 Total liabilities and shareholders’ equity ​ 1,373,523 1,370,186 ​
