The shares of common stock of Orthofix, as the corporate parent entity in the combined company structure, continue to trade on NASDAQ under the symbol "OFIX". The combined company will be renamed at a later date and until then will continue to be known as Orthofix Medical Inc. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Pursuant to these rules and regulations, certain information and note disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. In the opinion of management, all adjustments (consisting of normal recurring items) considered necessary for a fair statement have been included. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes contained in the Company’s Form 10-K for the year ended December 31, 2022. Operating results for the three months ended March 31, 2023, are not necessarily indicative of the results that may be expected for other interim periods or the year ending December 31, 2023. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. On an ongoing basis, the Company evaluates its estimates, including those related to revenue recognition; contractual allowances; allowances for expected credit losses; inventories; valuation of intangible assets; goodwill; fair value measurements, including contingent consideration; litigation and contingent liabilities; tax matters; and share-based compensation. Actual results could differ from these estimates. Changes in Presentation of Consolidated Financial Statements Certain prior year balances have been reclassified in the Condensed Consolidated Financial Statements to conform to current period presentation.

Accounting Changes and Error Corrections [Abstract]
Recently adopted accounting standards, recently issued accounting pronouncements	2. Recently adopted accounting standards, recently issued accounting pronouncements Adoption of Accounting Standards Update (“ASU”) 2021-08— Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers In October 2021, the Financial Accounting Standards Board (“FASB”) issued ASU 2021-08, which aims to address diversity in practice and inconsistency related to the accounting for acquired revenue contracts with customers in a business combination. The amendments require that an entity recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606. The Company adopted this standard effective January 1, 2023, on a prospective basis. Adoption of this standard resulted in the recognition of $ 2.2 million in contract liabilities associated with acquired revenue contracts as a result of the Company’s merger with SeaSpine, which closed on January 5, 2023. Recently Issued Accounting Pronouncements Topic Description of Guidance Effective Date Status of Company's Evaluation Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions (ASU 2022-03) Clarifies the guidance in Topic 820, Fair Value Measurement, when measuring the fair value of an equity security subject to contractual restrictions that prohibit the sale of an equity security and introduces new disclosure requirements for equity securities subject to contractual sale restrictions. Certain of the provisions are to be applied retrospectively with other provisions applied prospectively. January 1, 2024 The Company is currently evaluating the impact this ASU may have on its consolidated financial statements. Other recently issued ASUs, excluding those ASUs which have already been disclosed as adopted or described above, were assessed and determined not applicable, or are expected to have minimal impact on the Company's condensed consolidated financial statements.

Business Combinations [Abstract]
Merger and Acquisitions	3. Merger and acquisitions Merger with SeaSpine On January 5, 2023, the Company and SeaSpine completed an all-stock merger of equals (the "Merger") to create a leading global spine and orthopedics company with highly complementary portfolios of biologics, innovative spinal hardware, bone growth therapies, specialized orthopedic solutions, and a leading surgical navigation system. As a result of the Merger, each share of SeaSpine common stock issued and outstanding immediately prior to the closing of the Merger was converted into the right to receive 0.4163 shares of Orthofix common stock. The Merger is being accounted for as an acquisition of SeaSpine by Orthofix under the acquisition method of accounting for business combinations in accordance with U.S. GAAP. Thus, Orthofix is treated as the acquirer for accounting purposes. In identifying the acquirer, Orthofix and SeaSpine considered the structure of the transaction and other actions contemplated by the merger agreement (the “Merger Agreement”), relative outstanding share ownership, and market values, the composition of the combined company's board of directors, and the relative size of Orthofix and SeaSpine. Under the acquisition method of accounting, the assets and liabilities of SeaSpine and its subsidiaries have been recorded at their respective fair values as of the date of completion of the Merger. The total estimated fair value of consideration associated with the Merger as of the acquisition date was comprised of: (Unaudited, U.S. Dollars, in thousands, except shares and price per share) Share Consideration: Orthofix common shares to be issued in exchange for SeaSpine common shares 16,047,315 Orthofix closing price per share as of January 4, 2023 $ 22.76 Estimated fair value of shares issued in exchange for SeaSpine common shares $ 365,237 Estimated fair value of Orthofix stock options and RSUs issued in exchange for outstanding SeaSpine equity awards $ 11,508 Total estimated fair value of consideration $ 376,745 The following table summarizes the preliminary estimated fair values of the assets acquired and liabilities assumed at the acquisition date using Level 3 inputs. A final determination of the allocation of the purchase price to assets acquired and liabilities assumed has not been made and the following should be considered preliminary. Adjustments to the preliminary purchase price allocation could be material. The final determination is subject to completion of the Company's valuation of the assets acquired and liabilities assumed, including contingent liabilities and deferred income taxes, which it expects to complete within one year of the acquisition date. (Unaudited, U.S. Dollars, in thousands, except shares and price per share) As of January 5, 2023 Assigned Useful Life Assets acquired: Current assets Cash and cash equivalents $ 29,419 Accounts receivable, net 35,313 Inventories 129,610 Prepaid expenses and other current assets 4,600 Total current assets 198,942 Property, plant, and equipment, net 68,911 Customer relationships 27,100 13 years Developed technology 45,400 6 - 8 years In-process research and development ("IPR&D") 5,600 Indefinite Other long-term assets 20,472 Total identifiable assets acquired $ 366,425 Liabilities assumed : Current liabilities Accounts payable $ 21,602 Other current liabilities 41,224 Total current liabilities 62,826 Long-term borrowings under SeaSpine credit facility 26,298 Other long-term liabilities 31,950 Total liabilities assumed 121,074 Net identifiable assets acquired $ 245,351 Total fair value of consideration transferred 376,745 Residual goodwill $ 131,394 The purchase price exceeded the fair value of the net tangible and identifiable intangible assets acquired in the Merger. As a result, the Company recorded goodwill totaling $ 131.4 million, which was assigned to the Global Spine reporting segment. Specifically, the goodwill includes the assembled workforce and synergies associated with the combined entity. The goodwill is not deductible for tax purposes. The IPR&D intangible assets are considered an indefinite-lived asset until the completion or abandonment of the associated research and development efforts. Accordingly, during the development period after the acquisition, these assets are not amortized but, instead, are subject to impairment assessment. Upon completion of each IPR&D project, the Company will determine the useful life of the asset and begin amortization. The Company recognized $ 6.5 million in acquisition-related costs that were expensed during the three months ended March 31, 2023 . These costs are included in the condensed consolidated statements of operations and comprehensive income (loss), primarily within general and administrative expenses. The Company's results of operations included $ 60.9 million of net sales from SeaSpine and a net loss attributable to SeaSpine of $ 27.9 million for the period from January 5 through March 31, 2023. Pro Forma Financial Information Due to the Merger closing on January 5, 2023, all SeaSpine financial results in the first quarter of 2023, except for the first four days of January, is included in Orthofix's condensed consolidated statement of operations and comprehensive income (loss). The following unaudited pro forma financial information for the three months ended March 31, 2022 , is based on our historical condensed consolidated financial statements adjusted to reflect as if the Merger closed as of January 1, 2022. The unaudited pro-forma information makes certain adjustments to depreciation and amortization expense to reflect the fair value recognized in the purchase price allocation and removes one-time transaction-related costs. The unaudited pro forma financial information is presented for informational purposes only and is not indicative of the results of operations that would have been achieved if Merger closed as of January 1, 2022.

The Company also entered into a Convertible Loan Agreement pursuant to which the Company loaned Neo Medical CHF 4.6 million, or $ 5.0 million at the date of issuance (the “Convertible Loan”). In October 2021, the Company entered into a second Convertible Loan Agreement (the “Second Convertible Loan” and together with the Convertible Loan, the “Neo Medical Convertible Loans”), pursuant to which the Company loaned Neo Medical an additional CHF 0.6 million, or $ 0.7 million as of the date of issuance. The equity securities are recorded in other long-term assets and are considered an investment that does not have a readily determinable fair value. As such, the Company measures this investment at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for identical or similar investments of the same issuer. The table below presents a reconciliation of the beginning and ending balances of the Company’s investment in Neo Medical preferred equity securities: (Unaudited, U.S. Dollars, in thousands) 2023 2022 Fair value of Neo Medical preferred equity securities at January 1 $ 6,084 $ 5,413 Conversion of loan into preferred equity securities — 671 Fair value of Neo Medical preferred equity securities at March 31 6,084 6,084 Cumulative unrealized gain on Neo Medical preferred equity securities 413 413 The Company elected to convert the Second Convertible Loan into shares of Neo Medical’s preferred equity securities in January 2022. The Convertible Loan is recorded in other long-term assets as an available for sale debt security as of March 31, 2023. The fair value of the Convertible Loan is based upon significant unobservable inputs, including the use of option-pricing models, Monte Carlo simulations for certain periods, and a probability-weighted discounted cash flow model, requiring the Company to develop its own assumptions. Therefore, the Company categorized these investments as Level 3 financial assets. Some of the more significant unobservable inputs used in the fair value measurement of the Convertible Loan include applicable discount rates, implied volatility, the likelihood and projected timing of repayment or conversion, and projected cash flows in support of the estimated enterprise value of Neo Medical. Holding other inputs constant, changes in these assumptions could result in a significant change in the fair value of the Convertible Loan. If the amortized cost of the Convertible Loan exceeds its estimated fair value, the security is deemed to be impaired, and must be evaluated for the recognition of a credit loss. As of March 31, 2023 , the Company has no t recognized any credit loss related to the Convertible Loan. The following table provides a reconciliation of the beginning and ending balances of the Convertible Loans, measured at fair value using significant unobservable inputs (Level 3): (Unaudited, U.S. Dollars, in thousands) 2023 2022 Fair value of Neo Medical Convertible Loans at January 1 $ 7,140 $ 7,148 Interest recognized in interest income, net 116 112 Foreign currency remeasurement recognized in other expense, net 61 ( 69 ) Unrealized loss recognized in other comprehensive loss ( 137 ) ( 740 ) Conversion of Second Convertible Loan into preferred equity securities — ( 671 ) Fair value of Neo Medical Convertible Loans at March 31 7,180 5,780 Amortized cost basis of Neo Medical Convertible Loans at March 31 6,084 5,581 The following table provides quantitative information related to certain key assumptions utilized within the valuation as of March 31, 2023: (Unaudited, U.S. Dollars, in thousands) Fair Value as of Unobservable inputs Estimate Neo Medical Convertible Loan $ 7,180 Cost of equity discount rate 18.0 % Estimated equity volatility 77.5 % Bone Biologics Equity Securities Until August 2022, the Company held an investment in common stock of Bone Biologics Inc. (“Bone Biologics”, NASDAQ: BBLG), a developer of orthobiologic products. The Company disposed of its remaining holdings in Bone Biologics equity securities during the third quarter of 2022. Other Investments Other investments represent assets and investments recorded at fair value that are not deemed to be material for disclosure on an individual basis. The fair value of these assets is based upon significant unobservable inputs, such as probability-weighted discounted cash flow models, requiring the Company to develop its own assumptions. Therefore, the Company has categorized these assets as Level 3 financial assets. As of March 31, 2023, this balance was classified within other long-term assets. Spinal Kinetics Contingent Consideration The Company recognized a contingent consideration obligation in connection with the acquisition of Spinal Kinetics in 2018. The estimated fair value of the remaining Spinal Kinetics contingent consideration, attributable to a revenue-based milestone, was concluded to be zero as of March 31, 2023, as the Company did not achieve the milestone prior to April 30, 2023, the end of the measurement period for achieving such milestone. The following table provides a reconciliation of the beginning and ending balances for the Spinal Kinetics contingent consideration measured at estimated fair value using significant unobservable inputs (Level 3): (Unaudited, U.S. Dollars, in thousands) 2023 2022 Spinal Kinetics contingent consideration estimated fair value at January 1 $ — $ 17,200 Decrease in fair value recognized in acquisition-related amortization and remeasurement — ( 5,500 ) Spinal Kinetics contingent consideration estimated fair value at March 31 $ — $ 11,700 Lattus Contingent Consideration In connection with the Merger, the Company assumed a contingent consideration obligation under a purchase agreement between SeaSpine and Lattus Spine LLC ("Lattus") executed in December 2022. Under the terms of the agreement, the Company may be required to make installment payments at certain dates based on future net sales of certain products (the "Lateral Products"). The estimated fair value of the Lattus contingent consideration as of the closing of the Merger, January 5, 2023, was $ 11.5 million. The estimated fair value of the Lattus contingent consideration is determined using a probability-weighted discounted cash flow model and significant inputs which are not observable in the market. The significant inputs include assumptions related to the timing and probability of the product launch dates, estimated future sales of the products, estimated commission rates, discount rates matched to the timing of payments, and probability of success rates. The Company determined that the estimated fair value of the Lattus contingent consideration as of March 31, 2023, also approximated the fair value of the contingent liability as of the closing of the Merger .

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	8. Commitments and Contingencies Commitments As a result of the Merger, the Company became party to agreements with certain distributor partners that provide the Company with an option to purchase, and an option for those partners to require the Company to purchase, the distribution business of those partners at specified future dates. At such time, the Company or distributor may (in certain cases, subject to satisfying certain conditions) submit written notice to the other of its intention to exercise its rights and initiate or require the purchase. Upon receipt of the written notice, the Company and the distributor will work in good faith to consummate the purchase. Under these agreements, the purchase price would be paid in shares of the Company's common stock. Based on the closing price of the Company's common stock as of March 31, 2023 , assuming the options under all the relevant agreements were exercised, the estimated total shares the Company would issue under these agreements was 1.3 million shares. Contingencies In addition to the matters described below, in the normal course of its business, the Company is involved in various lawsuits from time to time and may be subject to certain other contingencies. The Company believes any losses related to these matters are individually and collectively immaterial as to a possible loss and range of loss. Italian Medical Device Payback (“IMDP”) In 2015, the Italian Parliament introduced rules for entities that supply goods and services to the Italian National Healthcare System. A key provision of the law is a ‘payback’ measure, requiring medical device companies in Italy to make payments to the Italian government if medical device expenditures exceed regional maximum ceilings. Companies are required to make payments equal to a percentage of expenditures exceeding maximum regional caps. In the third quarter of 2022, the Italian Ministry of Health provided guidelines to the Italian regions and provinces on seeking payback of expenditure overruns relating to the years ended December 31, 2015, through December 31, 2018. Since receiving the guidelines, several regions and provinces have requested payment from affected medical device companies, including the Company. The Company has taken legal action to dispute the legality of such measures. The Company accounts for the estimated cost of the IMDP as sales and marketing expense and periodically reassesses the liability based upon current facts and circumstances. As a result, the Company recorded an expense of $ 0.3 million and $ 0.3 million for the quarter ended March 31, 2023, and March 31, 2022, respectively. As of March 31, 2023 , the Company has accrued $ 6.3 million related to the IMDP, which it has classified within other long-term liabilities; however, the actual liability could be higher or lower than the amount accrued once all legal proceedings are resolved and upon further clarification of the IMDP by the Italian authorities for more recent fiscal years.

Income Tax Disclosure [Abstract]
Income taxes	14. Income taxes Generally, income tax provisions for interim periods are based on an estimated annual income tax rate, adjusted for discrete tax items, with any changes affecting the estimated annual effective tax rate recorded in the interim period in which the change occurs. Due to the impact of losses not benefitted by the Company’s U.S. operations, the Company determined the estimated annual effective tax rate method would not provide a reliable estimate of the Company’s overall annual effective tax rate. As such, the Company has calculated the tax provision using the actual effective rate for the three months ended March 31, 2023. Due to the impact of temporary differences on the U.S. current tax liability without any deferred tax benefit, the actual effective rate may vary in future quarters. For the three months ended March 31, 2023 and 2022, the effective tax rate was ( 1.0 %) and ( 1.6 %), respectively. The primary factors affecting the Company’s effective tax rate for the three months ended March 31, 2023 , were certain losses not benefitted.

Accounting Changes and Error Corrections [Abstract]
Recently adopted accounting standards and recently issued accounting pronouncements	Adoption of Accounting Standards Update (“ASU”) 2021-08— Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers In October 2021, the Financial Accounting Standards Board (“FASB”) issued ASU 2021-08, which aims to address diversity in practice and inconsistency related to the accounting for acquired revenue contracts with customers in a business combination. The amendments require that an entity recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606. The Company adopted this standard effective January 1, 2023, on a prospective basis. Adoption of this standard resulted in the recognition of $ 2.2 million in contract liabilities associated with acquired revenue contracts as a result of the Company’s merger with SeaSpine, which closed on January 5, 2023. Recently Issued Accounting Pronouncements Topic Description of Guidance Effective Date Status of Company's Evaluation Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions (ASU 2022-03) Clarifies the guidance in Topic 820, Fair Value Measurement, when measuring the fair value of an equity security subject to contractual restrictions that prohibit the sale of an equity security and introduces new disclosure requirements for equity securities subject to contractual sale restrictions. Certain of the provisions are to be applied retrospectively with other provisions applied prospectively. January 1, 2024 The Company is currently evaluating the impact this ASU may have on its consolidated financial statements. Other recently issued ASUs, excluding those ASUs which have already been disclosed as adopted or described above, were assessed and determined not applicable, or are expected to have minimal impact on the Company's condensed consolidated financial statements.
