BASIS OF PREPARATION AND PRESENTATION
BASIS OF PREPARATION AND PRESENTATION	1. BASIS OF PREPARATION AND PRESENTATION Allied Motion Technologies Inc. (“Allied Motion” or the “Company”) is engaged in the business of designing, manufacturing, and selling precision and specialty-controlled motion components and systems, which include integrated system solutions as well as individual controlled motion products, to a broad spectrum of customers throughout the world primarily for the vehicle, medical, aerospace and defense, and industrial markets. The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The assets and liabilities of the Company’s foreign subsidiaries are translated into U.S. dollars using end of period exchange rates. Changes in reported amounts of assets and liabilities of foreign subsidiaries that occur as a result of changes in exchange rates between the foreign subsidiaries’ functional currencies and the U.S. dollar are included in foreign currency translation adjustment. Foreign currency translation adjustment is included in accumulated other comprehensive loss, a component of stockholders’ equity in the accompanying condensed consolidated statements of stockholders’ equity. Revenue and expense transactions use an average rate prevailing during the month of the related transaction. Transaction gains and losses that arise from exchange rate fluctuations on transactions denominated in a currency other than the functional currency of each of the foreign subsidiaries are included in the results of operations as incurred in other (income) expense, net. The condensed consolidated financial statements included herein have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) and include all adjustments which are, in the opinion of management, necessary for a fair presentation. Certain information and footnote disclosures normally included in financial statements which are prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) have been condensed or omitted pursuant to such rules and regulations. The Company believes that the disclosures herein are adequate to make the information presented not misleading. The financial data for the interim periods may not necessarily be indicative of results to be expected for the year. The preparation of financial statements in accordance with U.S. GAAP requires management to make certain estimates and assumptions. Such estimates and assumptions affect the reported amounts of assets and liabilities as well as disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ materially from those estimates. It is suggested that the accompanying condensed consolidated financial statements be read in conjunction with the Consolidated Financial Statements and related Notes to such statements included in the Annual Report on Form 10-K for the year ended December 31, 2022 that was previously filed by the Company.

REVENUE RECOGNITION

REVENUE RECOGNITION
REVENUE RECOGNITION	3. REVENUE RECOGNITION Performance Obligations The Company considers control of most products to transfer at a single point in time when control is transferred to the customer, generally when the products are shipped in accordance with an agreement and/or purchase order. Control is defined as the ability to direct the use of and obtain substantially all of the remaining benefits of the product. The Company satisfies its performance obligations under a contract with a customer by transferring goods and services in exchange for monetary consideration from the customer. The Company considers the customer’s purchase order, and the Company’s corresponding sales order acknowledgment as the contract with the customer. For some customers, control, and a sale, is transferred at a point in time when the product is delivered to a customer. For a limited number of contracts, for which revenue derived is not material in the periods presented, the Company recognizes revenue over time in proportion to costs incurred. Sales, value add, and other taxes the Company collects concurrent with revenue-producing activities are excluded from revenue. Nature of Goods and Services The Company sells component and integrated controlled motion solutions to end customers and original equipment manufacturers (“OEM’s”) through the Company’s own direct sales force and authorized manufacturers’ representatives and distributors. The Company’s products include brushed and brushless DC motors, brushless servo and torque motors, coreless DC motors, integrated brushless motor-drives, gearmotors, gearing, modular digital servo drives, motion controllers, incremental and absolute optical encoders, active and passive filters for power quality and harmonic issues, and other controlled motion-related products. The Company’s target markets include Industrial, Vehicle, Medical, and Aerospace & Defense Determining the Transaction Price The majority of the Company’s contracts have an original duration of less than one year. For these contracts, the Company applies the practical expedient and therefore does not consider the effects of the time value of money. For multiyear contracts, the Company uses judgment to determine whether there is a significant financing component. These contracts are generally those in which the customer has made an up-front payment. Contracts that management determines to include a significant financing component are discounted at the Company’s incremental borrowing rate. The Company incurs interest expense and accrues a contract liability. As the Company satisfies performance obligations and recognizes revenue from these contracts, interest expense is recognized simultaneously. Management does not have any contracts that include a significant financing component as of June 30, 2023 and December 31, 2022. Disaggregation of Revenue The Company disaggregates revenue from contracts with customers into geographical regions and target markets. The Company determines that disaggregating revenue into these categories achieves the disclosure objective to depict how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors.

Typically, contracts are paid in arrears and are recognized as receivables after the Company considers whether a significant financing component exists. The opening and closing balances of the Company’s contract liabilities are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, ​ December 31, ​ ​ 2023 ​ 2022 Contract liabilities in accrued liabilities ​ $ 3,620 ​ $ 4,807 Contract liabilities in other long-term liabilities ​ ​ 14 ​ ​ 19 ​ ​ $ 3,634 ​ $ 4,826 ​ ​ ​ ​ ​ ​ ​ ​ The difference between the opening and closing balances of the Company’s contract liabilities primarily results from the timing difference between the Company’s performance and the customer’s payment. Significant Payment Terms The Company’s contracts with its customers state the final terms of the sale, including the description, quantity, and price of each product or service purchased. Payments are typically due in full within 30-60 days of delivery. Since the customer agrees to a stated rate and price in the contract that do not vary over the contract, the majority of contracts do not contain variable consideration. Returns, Refunds, and Warranties In the normal course of business, the Company does not accept product returns unless the item is defective as manufactured. The Company establishes provisions for estimated returns and warranties. All contracts include a standard warranty clause to guarantee that the product complies with agreed specifications. ​

Amended Revolving Credit Facility The Second Amended and Restated Credit Agreement (the “Amended Credit Agreement”), effective August 23, 2022, includes a $280 million revolving credit facility (the “Amended Revolving Facility”). In the Amended Credit Agreement, the referenced index was amended to the Term Standard Overnight Financing Rate (“SOFR”), whereas the previous credit agreement utilized the London Interbank Offering Rate (LIBOR) as the referenced interest rate. The Amended Credit Agreement has a maturity date of February 2025. Borrowings under the Amended Revolving Facility bear interest at an annual rate equal to the Adjusted SOFR (as defined in the Amended Credit Agreement) which is subject to a floor of 0.00% plus an applicable margin spread ranging from 1.00% to 2.25% (1.75% at June 30, 2023) based on the Company’s ratio of total funded indebtedness to consolidated trailing twelve-month EBITDA (the “Total Leverage Ratio”). In addition, the Company is required to pay a commitment fee of between annually on the unused portion of the Amended Revolving Facility, also based on the Company’s Total Leverage Ratio. The Amended Revolving Facility is secured by substantially all of the Company’s non-realty assets and is fully and unconditionally guaranteed by certain of the Company’s subsidiaries. The Amended Credit Agreement includes covenants and restrictions that limit the Company’s ability to incur additional indebtedness, make certain investments, create, incur or assume certain liens, merge, consolidate or sell all or substantially all of its assets and enter into transactions with an affiliate of the Company on other than an arms’ length transaction. These covenants, which are described more fully in the Amended Credit Agreement, to which reference is made for a complete statement of the covenants, are subject to certain exceptions. The Amended Credit Agreement contains financial covenants that require that the Company maintain a minimum interest coverage ratio of at least 3.0 to 1.0 at the end of each fiscal quarter. In addition, the Company’s Leverage Ratio at the end of any fiscal quarter shall not be greater than (reduced to 3.5 :1.0 for quarters ending on or after December 31, 2023); provided that the Company may elect to temporarily increase the Leverage Ratio by 0.5 x during the twelve-month period following a material acquisition under the Amended Credit Agreement (“acquisition leverage increase”), subject to certain exceptions. The Company was in compliance with all covenants as of June 30, 2023 As of June 30, 2023, the unused Amended Revolving Facility was $61,234 . The amount available to borrow may be limited by the Company’s debt and EBITDA levels, which impacts its covenant calculations. Other The China Credit Facility (“the China Facility”) provided credit of $1,444 (Chinese Renminbi 10,000 ). The China Facility was a demand revolving facility used for working capital and capital equipment needs at the Company’s China operations. The term was annual and cancelleable at the bank’s discretion. The interest rate shall be agreed upon by the Lender and the Borrower before the Utilization Date (as defined in the China Facility) and shall be specified in the Utilization Request (as defined in the China Facility).

DERIVATIVE FINANCIAL INSTRUMENTS
DERIVATIVE FINANCIAL INSTRUMENTS	11. DERIVATIVE FINANCIAL INSTRUMENTS The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, and foreign exchange risk primarily through the use of derivative financial instruments. The Company enters into foreign currency contracts with 30-day The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements on its variable-rate debt. To accomplish this objective, the Company primarily uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. In February 2017, the Company entered into that matures in December 2026. In March 2023, the Company executed amendments to the existing swaps to amend the index on the interest rate derivatives from LIBOR to SOFR, in line with the existing Amended Revolving Facility. These amendments had no material financial impact to the Company’s operations or financial position. The changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive loss and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. During 2023 and 2022, such derivatives were used to hedge the variable cash flows associated with existing variable-rate debt. The Company estimates that $3,930 will be reclassified as a decrease to interest expense over the next twelve months related to its interest rate derivatives. The Company does not use derivatives for trading or speculative purposes.

FAIR VALUE
FAIR VALUE	12. FAIR VALUE Authoritative guidance defines fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. The guidance establishes a framework for measuring fair value which utilizes observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. Preference is given to observable inputs. These two types of inputs create the following three - level fair value hierarchy: Level 1: Quoted prices for identical assets or liabilities in active markets. ​ Level 2: Quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; and model - derived valuations whose inputs or significant value drivers are observable. ​ Level 3: Significant inputs to the valuation model that are unobservable. ​ The Company’s financial assets and liabilities include cash and cash equivalents, accounts receivable, debt obligations, accounts payable, and accrued liabilities. The carrying amounts reported in the condensed consolidated balance sheets for these assets and liabilities approximate their fair value because of the immediate or short-term maturities of these financial instruments. The following tables presents the Company’s financial assets that are accounted for at fair value on a recurring basis as of June 30, 2023 and December 31, 2022, respectively, by level within the fair value hierarchy: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, 2023 ​ Level 1 Level 2 Level 3 Assets (liabilities) ​ ​ ​ ​ ​ ​ ​ ​ ​ Pension plan assets ​ $ 5,730 ​ $ — ​ $ — Deferred compensation plan assets ​ 4,141 ​ — ​ — Foreign currency hedge contract assets ​ ​ — ​ ​ 30 ​ ​ — Foreign currency hedge contract liabilities ​ — ​ (27) ​ — Interest rate swaps, net ​ — ​ 6,675 ​ — Contingent consideration ​ — ​ — ​ (4,100) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2022 ​ Level 1 Level 2 Level 3 Assets (liabilities) ​ ​ ​ ​ ​ ​ ​ ​ ​ Pension plan assets ​ $ 5,324 ​ $ — ​ $ — Deferred compensation plan assets ​ 3,870 ​ — ​ — Foreign currency hedge contracts ​ — ​ 48 ​ — Interest rate swaps, net ​ — ​ 7,236 ​ — Contingent consideration ​ — ​ — ​ (4,100) ​ ​ ​ ​ The contingent consideration fair value measurement in connection with the acquisition of ALIO Industries (“ALIO”) is based on significant inputs not observable in the market and therefore constitute Level 3 inputs within the fair value hierarchy. The Company determines the initial fair value of contingent consideration liabilities using a Monte Carlo valuation model, which involves a simulation of future earnings generated during the earn-out period using management’s best estimates, or a probability-weighted discounted cash flow analysis. There were no change to the estimated fair value of contingent consideration during the three and six months ended June 30, 2023, and the contingent consideration of $4,100 as of June 30, 2023 is included in other long-term liabilities on the condensed consolidated balance sheet.

INCOME TAXES The income tax provision for interim periods is determined using an estimate of the annual effective tax rate, adjusted for discrete items, if any, that are taken into account in the relevant period. Each quarter, the estimate of the annual effective tax rate is updated, and if the estimated effective tax rate changes, a cumulative adjustment is made. There is potential for volatility of the effective tax rate due to several factors, including changes in the mix of the pre-tax income and the jurisdictions to which it relates, changes in tax laws, settlements with taxing authorities and foreign currency fluctuations. ​ The effective income tax rate was 23.9% and 27.0% for the three months ended June 30, 2023 and 2022, respectively.
