Accounting Policies [Abstract]
Organization and Significant Accounting Policies	1. Organization and Significant Accounting Policies The Company Alphatec Holdings, Inc. (the “Company”), through its wholly owned subsidiaries, Alphatec Spine, Inc. (“Alphatec Spine”), SafeOp Surgical, Inc. (“SafeOp”), and EOS imaging S.A. (“EOS”), is a medical technology company that designs, develops, and markets technology for the treatment of spinal disorders associated with disease and degeneration, congenital deformities, and trauma. The Company markets its products in the United States of America and internationally via a network of independent sales agents and direct sales representatives. Basis of Presentation and Principles of Consolidation The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. The Company translates the financial statements of its foreign subsidiaries using end-of-period exchange rates for assets and liabilities and average exchange rates during each reporting period for results of operations. All intercompany balances and transactions have been eliminated during consolidation. The accompanying condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Pursuant to these rules and regulations, the Company has condensed or omitted certain information and footnotes it normally includes in its annual consolidated financial statements prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”). The unaudited interim condensed consolidated financial statements reflect all adjustments, including normal recurring adjustments which, in the opinion of management, are necessary for a fair statement of the financial position and results of operations for the periods presented. These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements for the year ended December 31, 2022, which are included in the Company’s Annual Report on Form 10-K that was filed with the SEC. Operating results for the three months ended March 31, 2023 are not necessarily indicative of the results that may be expected for the year ending December 31, 2023, or any other future periods. Prior-period Adjustment Subsequent to the issuance of the Company’s consolidated financial statements as of and for the year ended December 31, 2022, the Company identified that a deferred tax liability and additional goodwill related to the acquisition of EOS should have been recorded at the time of the acquisition. The Company corrected the errors in the accompanying condensed consolidated financial statements as of the earliest period presented and has concluded that the correction of these errors is not material to the previously issued financial statements. The correction to the accompanying unaudited condensed consolidated balance sheets, condensed consolidated statements of operations, condensed consolidated statements of comprehensive loss, condensed consolidated statements of stockholder's equity, and condensed consolidated statements of cash flows are as follows (in thousands): At December 31, 2021 Condensed Consolidated Statements of Stockholder's Equity As Reported Adjustment As Corrected Accumulated other comprehensive loss $ ( 5,994 ) $ ( 42 ) $ ( 6,036 ) Accumulated deficit ( 782,325 ) 1,294 ( 781,031 ) Total stockholder's equity $ 79,422 $ 1,252 $ 80,674 At December 31, 2022 Condensed Consolidated Balance Sheets As Reported Adjustment As Corrected Goodwill $ 39,775 $ 7,592 $ 47,367 Total Assets 513,376 7,592 520,968 Other long-term liabilities 11,543 5,546 17,089 Accumulated other comprehensive deficit ( 10,690 ) ( 104 ) ( 10,794 ) Accumulated deficit ( 934,474 ) 2,150 ( 932,324 ) Total stockholder's deficit ( 36,713 ) 2,046 ( 34,667 ) Total liabilities and stockholders' deficit $ 513,376 $ 7,592 $ 520,968 Three Months Ended March 31, 2022 Condensed Consolidated Statements of Operations As Reported Adjustment As Corrected Income tax provision (benefit) $ 129 $ ( 228 ) $ ( 99 ) Net loss $ ( 42,844 ) $ 228 $ ( 42,616 ) Three Months Ended March 31, 2022 Condensed Consolidated Statements of Comprehensive Loss As Reported Adjustment As Corrected Net loss $ ( 42,844 ) $ 228 $ ( 42,616 ) Foreign currency translation adjustments ( 1,180 ) ( 24 ) ( 1,204 ) Comprehensive loss $ ( 44,024 ) $ 204 $ ( 43,820 ) Three Months Ended March 31, 2022 Condensed Consolidated Statements of Stockholder's Equity As Reported Adjustment As Corrected Foreign currency translation adjustments $ ( 1,180 ) $ ( 24 ) $ ( 1,204 ) Net loss ( 42,844 ) 228 ( 42,616 ) Total stockholder's equity $ 41,984 $ 1,456 $ 43,440 Three Months Ended March 31, 2022 Condensed Consolidated Statements of Cash Flows As Reported Adjustment As Corrected Net loss $ ( 42,844 ) $ 228 $ ( 42,616 ) Other long-term liabilities ( 716 ) ( 221 ) ( 937 ) Net cash used for operating activities ( 24,712 ) 7 ( 24,705 ) Effect of exchange rate changes on cash $ ( 14 ) $ ( 7 ) $ ( 21 ) Reclassification Certain financial statement line items in the condensed consolidated financial statements for the three months ended March 31, 2022 have been disaggregated into multiple financial statement line items to conform to the current year’s presentation. Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of revenues and expenses. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include the useful lives of property and equipment, goodwill, intangible assets, allowances for doubtful accounts, deferred tax assets, inventory, stock-based compensation, revenues, income tax uncertainties, and other contingencies. Fair Value Measurements The carrying amount of financial instruments consisting of cash and cash equivalents, accounts receivable, prepaid expenses and other current assets, accounts payable, accrued expenses, and short-term debt included in the Company’s condensed consolidated financial statements are reasonable estimates of fair value due to their short maturities. Authoritative guidance establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: Level 1: Quoted prices in active markets for identical assets or liabilities. Level 2: Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active; or other inputs that can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3: Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Excess and Obsolete Inventory Most of the Company’s inventory is comprised of finished goods, which is primarily produced by third-party suppliers. Specialized implants, fixation products, biologics, and disposables are determined by utilizing a standard cost method that includes capitalized variances which approximates the weighted average cost. Imaging equipment and related parts are valued at weighted average cost. Inventories are stated at the lower of cost or net realizable value. The Company reviews the components of its inventory on a periodic basis for excess and obsolescence and adjusts inventory to its net realizable value as necessary. The Company records a lower of cost or net realizable value (“LCNRV”) inventory reserve for estimated excess and obsolete inventory based upon its expected use of inventory on hand. The Company’s inventory, which consists primarily of specialized implants, fixation products, biologics, and disposables is at risk of obsolescence due to the need to maintain substantial levels of inventory. In order to market its products effectively and meet the demands of interoperative product placement, the Company maintains and provides surgeons and hospitals with a variety of inventory products and sizes. For each surgery, fewer than all components will be consumed. The need to maintain and provide a wide variety of inventory causes inventory to be held that is not likely to be used. The Company’s estimates and assumptions for excess and obsolete inventory are reviewed and updated on a quarterly basis. The estimates and assumptions are determined primarily based on current usage of inventory and the age of inventory quantities on hand. Additionally, the Company considers recent sales experience to develop assumptions about future demand for its products, while considering product life cycles and new product launches. Increases in the LCNRV reserve for excess and obsolete inventory result in a corresponding charge to cost of sales. Revenue Recognition The Company recognizes revenue from product sales in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Revenue from Contracts with Customers (“Topic 606”). This standard applies to all contracts with customers, except for contracts that are within the scope of other standards, such as leases, insurance, collaboration arrangements, and financial instruments. Under Topic 606, an entity recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration that the entity expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of Topic 606, the entity performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. The Company only applies the five-step model to contracts when it is probable that the entity will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. Sales are derived primarily from the sale of spinal implant products, imaging equipment, and related services to hospitals and medical centers through direct sales representatives and independent sales agents. Revenue is recognized when obligations under the terms of a contract with customers are satisfied, which occurs with the transfer of control of products to customers, either upon shipment of the product or delivery of the product to the customer depending on the shipping terms, or when the products are used in a surgical procedure (implanted in a patient). Revenue from the sale of imaging equipment is recognized as each distinct performance obligation is fulfilled and control transfers to the customer, beginning with shipment or delivery, depending on the terms. Revenue from other distinct performance obligations, such as maintenance on imaging equipment and other imaging-related services, is recognized in the period the service is performed, and makes up less than 10 % of the Company’s total revenue. Revenue is measured based on the amount of consideration expected to be received in exchange for the transfer of the goods or services specified in the contract with each customer. In certain cases, the Company does offer the ability for customers to lease its imaging equipment primarily on a non-sales type basis, but such arrangements are immaterial to total revenue in the periods presented. The Company generally does not allow returns of products that have been delivered. Costs incurred by the Company associated with sales contracts with customers are deferred over the performance obligation period and recognized in the same period as the related revenue, except for contracts that complete within one year or less, in which case the associated costs are expensed as incurred. Payment terms for sales to customers may vary but are commensurate with the general business practices in the country of sale. To the extent that the transaction price includes variable consideration, such as discounts, rebates, and customer payment penalties, the Company estimates the amount of variable consideration that should be included in the transaction price utilizing either the expected value method or the most likely amount method depending on the nature of the variable consideration. Variable consideration is included in the transaction price if, in the Company's judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur. Estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of the Company’s anticipated performance and all information that is reasonably available, including historical, current, and forecasted information. The Company records a contract liability, or deferred revenue, when it has an obligation to provide a product or service to the customer and payment is received in advance of its performance. When the Company sells a product or service with a future performance obligation, revenue is deferred on the unfulfilled performance obligation and recognized over the related performance period. Generally, the Company does not have observable evidence of the standalone selling price related to its future service obligations; therefore, the Company estimates the selling price using an expected cost plus a margin approach. The transaction price is allocated using the relative standalone selling price method. The use of alternative estimates could result in a different amount of revenue deferral. Recently Adopted and Issued Accounting Pronouncements In August 2021, the FASB issued Accounting Standards Update ("ASU") No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers . The guidance requires application of Topic 606, Revenue from Contracts with Customers to recognize and measure contract assets and contract liabilities acquired in a business combination. ASU No. 2021-08 adds an exception to the general recognition and measurement principle in Topic 805 where assets acquired and liabilities assumed in a business combination, including contract assets and contract liabilities arising from contracts with customers, are measured at fair value on the acquisition date. Under the new guidance, the acquirer will recognize acquired contract assets and contract liabilities as if the acquirer had originated the contract. The standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022, with early adoption permitted. The Company adopted ASU No. 2021-08 as of January 1, 2023, on a prospective basis. The adoption of ASU No. 2021-08 did not have a material impact on the Company's condensed consolidated financial statements and related disclosures.

Debt Disclosure [Abstract]
Debt	7. Debt Term Loan On January 6, 2023, the Company entered into a $ 150.0 million term loan credit facility with Braidwell Transaction Holdings, LLC (the “Braidwell Term Loan”). The Braidwell Term Loan provides for an initial term loan of $ 100.0 million which was funded on the closing date. The Company has the option to draw up to an additional $ 50.0 million within 18 months of the closing date (the “delayed draw term loan(s)” or the “DDTL”). The Braidwell Term Loan matures on January 6, 2028 . As of March 31, 2023 , the outstanding balance under the Braidwell Term Loan was $ 100.0 million. In conjunction with the issuance of the Braidwell Term Loan, the Company incurred $ 3.4 million in debt issuance costs and $ 1.5 million in commitment fees. Commitment fees paid to the lender were accounted for as a debt discount. The debt issuance costs and debt discount allocated to the undrawn portion of the loan, which were $ 1.1 million and $ 0.5 million, respectively, were recorded to other assets on the condensed consolidated balance sheets. The debt issuance costs and debt discount allocated to the drawn portion of the loan were recorded as a direct reduction of the carrying amount of the loan on the condensed consolidated balance sheets and are being amortized over the life of the loan. As of March 31, 2023, debt issuance costs and debt discount allocated to the drawn portion of the loan, net of accumulated amortization, associated with the Braidwell Term Loan were $ 2.2 million and $ 1.0 million, respectively. Borrowings under the Braidwell Term Loan bear interest at a rate per annum equal to the Term Secured Overnight Financing Rate for such SOFR business day ("SOFR") subject to a 3 % floor, plus 5.75 %. The applicable interest rate as of March 31, 2023 was 10.5 % . The loan agreement includes an undrawn commitment fee, which is calculated as 1 % per annum of the average daily undrawn portion of the DDTL. Interest and undrawn commitment fees incurred are due quarterly. The Company is also required to pay fees on any prepayment of the Braidwell Term Loan, ranging from 3.0 % to 1.0 % depending on the date of prepayment, and a final payment fee equal to 3.25 % of the principal amount of the loans drawn. The effective interest rate as of March 31, 2023 was 11.11 %. During the three months ended March 31, 2023 , the Company recognized interest expense on the Braidwell Term Loan of $ 2.8 million, which includes $ 0.1 million for the amortization of debt issuance costs and $ 0.1 million for the debt discount. Upon the Braidwell Term Loan’s maturity, any outstanding principal balance, unpaid accrued interest, and all other obligations under the Braidwell Term Loan will be due and payable. The outstanding portion of the Braidwell Term Loan is secured by substantially all of the Company’s assets with the priority interest of the lenders in the Braidwell Term Loan and the Revolving Credit Facility, as defined below, subject to terms of a customary intercreditor agreement, which provides that the lenders under the Revolving Credit Facility have a priority with respect to the Company's accounts receivable, inventory, medical instruments, and items related to the foregoing, and the lenders under the Braidwell Term Loan have priority with respect to the remainder of the Company's assets. The loan agreement contains customary representations and warranties and affirmative and negative covenants. Under the loan agreement, the Company is required to maintain a minimum level of liquidity. The loan agreement also includes certain events of default, and upon the occurrence of such events of default, all outstanding loans under the Braidwell Term Loan may be accelerated and/or the lenders’ commitments terminated. The Company is in compliance with all required financial covenants as of March 31, 2023. Revolving Credit Facility In September 2022, the Company entered into a revolving credit facility (the “Revolving Credit Facility”) with entities affiliated with MidCap Financial Trust (“MidCap”). The Revolving Credit Facility provides up to $ 50.0 million in borrowing capacity to the Company based on a borrowing base. The borrowing base is calculated based on certain accounts receivable and inventory assets. The Company may request a $ 25.0 million increase in the Revolving Credit Facility for a total commitment of up to $ 75.0 million. The Revolving Credit Facility matures on the earlier of September 29, 2027 , or 90 days prior to the final maturity date of the Company’s 2026 Notes. As of March 31, 2023 , the outstanding balance under the Revolving Credit Facility was $ 8.1 million. In conjunction with obtaining the Revolving Credit Facility, the Company incurred $ 1.3 million in debt issuance costs. These costs were capitalized to other assets on the condensed consolidated balance sheets and are being amortized over the life of the Revolving Credit Facility. As of March 31, 2023, debt issuance costs, net of accumulated amortization, associated with the Revolving Credit Facility were $ 1.3 million. The outstanding loans under the Revolving Credit Facility bear interest at the sum of Term SOFR plus 3.5 % per annum. The interest rate as of March 31, 2023 was 8.4 %. The loan agreements include an unused line fee, which is calculated as 0.5 % per annum of either the unused Revolving Credit Facility or a minimum balance. Interest and unused line fees incurred are due and capitalized to the outstanding principal balance monthly. The Company recognized interest expense on the Revolving Credit Facility of $ 0.3 million during the three months ended March 31, 2023 , which includes $ 0.1 million for the amortization of debt issuance costs. Upon the Revolving Credit Facility’s maturity, any outstanding principal balance, unpaid accrued interest, and all other obligations under the Revolving Credit Facility will be due and payable. The Revolving Credit Facility contains a lockbox arrangement clause requiring the Company to maintain a lockbox bank account. If the revolving loan availability is less than 30 % of the revolving loan limit for five consecutive business days, or the Company is in default, MidCap will apply funds collected from the Company's lockbox account to reduce the outstanding balance of the Revolving Credit Facility. As of March 31, 2023, the Company's loan availability level has not activated lockbox deductions, nor is it expected to for the next 12 months; therefore, the Company has determined that the outstanding balance under the Revolving Credit Facility is long-term debt on the condensed consolidated balance sheets. The outstanding portion of the Revolving Credit Facility is secured by substantially all of the Company’s assets with the priority interest of the lenders subject to terms of a customary intercreditor agreement in connection with the Braidwell Term Loan, as described above. The loan agreements and other ancillary documents contain customary representations and warranties and affirmative and negative covenants. Under the loan agreements, the Company is required to maintain a minimum level of liquidity. The loan agreements also include certain events of default, and upon the occurrence of such events of default, all outstanding loans under the Revolving Credit Facility may be accelerated and/or the lenders’ commitments terminated. The Company is in compliance with all required financial covenants as of March 31, 2023. 0.75% Convertible Senior Notes due 2026 In August 2021, the Company issued $ 316.3 million aggregate principal amount of unsecured 2026 Notes with a stated interest rate of 0.75 % and a maturity date of August 1, 2026 . Interest on the 2026 Notes is payable semi-annually in arrears on February 1 and August 1 of each year, beginning on February 1, 2022 . The net proceeds from the sale of the 2026 Notes were approximately $ 306.2 million after deducting the initial purchasers’ offering expenses and before cash used for the privately negotiated capped call transactions (the “Capped Call Transactions”), as described below, the repurchase of stock, and the repayment of the outstanding term loan with Squadron Medical Finance Solutions, LLC, and outstanding obligations under an inventory financing agreement. The 2026 Notes do not contain any financial covenants. The 2026 Notes are convertible into shares of the Company’s common stock based upon an initial conversion rate of 54.5316 shares of the Company’s common stock per $ 1,000 principal amount of 2026 Notes (equivalent to an initial conversion price of approximately $ 18.34 per share). The conversion rate will be subject to adjustment upon the occurrence of certain specified events, including certain distributions and dividends to all or substantially all of the holders of the Company’s common stock. Based on the terms of the 2026 Notes, when a conversion notice is received, the Company has the option to pay or deliver cash, shares of the Company’s common stock, or a combination thereof. Holders of the 2026 Notes have the right to convert their notes in certain circumstances and during specified periods. Prior to the close of business on the business day immediately preceding February 2, 2026, holders may convert all or a portion of their 2026 Notes only under the following circumstances: (1) during any calendar quarter (and only during such calendar quarter) if the last reported sale price of the Company’s common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130 % of the conversion price on each applicable trading day; (2) during the 5 consecutive business days immediately after any 10 consecutive trading day period (the “measurement period”) in which the trading price per $ 1,000 principal amount of 2026 Notes for each trading day of the measurement period was less than 98 % of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such trading day; or (3) upon the occurrence of specified corporate events. From and after February 2, 2026 , holders of the 2026 Notes may convert their notes at any time at their election until the close of business on the second scheduled trading day immediately before the maturity date. As of March 31, 2023, none of the conditions permitting the holders of the 2026 Notes to convert have been met. The 2026 Notes are classified as long-term debt on the condensed consolidated balances sheet as of March 31, 2023. The 2026 Notes are redeemable, in whole or in part, at the Company’s option at any time, and from time to time, on or after August 6, 2024 and on or before the 40th scheduled trading day immediately before the maturity date, at a cash redemption price equal to the principal amount of the 2026 Notes to be redeemed, plus accrued and unpaid interest, if any, but only if the last reported sale price per share of the Company’s common stock exceeds 130 % of the conversion price for a specified period of time. In addition, calling any of the 2026 Notes for redemption will constitute a “make-whole fundamental change” with respect to the redeemable note, in which case the conversion rate applicable to the conversion of the redeemed note will be increased in certain circumstances if such note is converted after it is called for redemption. If a fundamental change occurs prior to the maturity date, holders may require the Company to repurchase all or a portion of their 2026 Notes for cash at a price equal to 100 % of the principal amount of the 2026 Notes plus accrued and unpaid interest. No principal payments are otherwise due on the 2026 Notes prior to maturity. The Company recorded the full principal amount of the 2026 Notes as a long-term liability net of deferred issuance costs. The annual effective interest rate for the 2026 Notes is 1.4 %. The Company recognized interest expense on the 2026 Notes of $ 1.1 million, which includes $ 0.5 million for the amortization of debt issuance costs, for the three months ended March 31, 2023 and 2022. The Company uses the if-converted method for assumed conversion of the 2026 Notes to compute the weighted-average shares of common stock outstanding for diluted earnings per share, if applicable. The outstanding principal amount and carrying value of the 2026 Notes consists of the following (in thousands): March 31, December 31, Principal $ 316,250 $ 316,250 Unamortized debt issuance costs ( 6,800 ) ( 7,290 ) Net carrying value $ 309,450 $ 308,960 Capped Call Transactions In connection with the offering of the 2026 Notes, the Company entered into the Capped Call Transactions with certain financial institutions. The Capped Call Transactions are expected generally to reduce the potential dilution and/or offset the cash payments the Company is required to make in excess of the principal amount of the 2026 Notes upon conversion of the 2026 Notes in the event that the market price per share of the Company’s common stock is greater than the strike price of the Capped Call Transactions with such reduction and/or offset subject to a cap. The Capped Call Transactions have an initial cap price of $ 27.68 per share of the Company’s common stock, which represents a premium of 100 % over the last reported sale price of the Company’s common stock on August 5, 2021, and is subject to certain adjustments under the terms of the Capped Call Transactions. Collectively, the Capped Call Transactions cover, initially, the number of shares of the Company’s common stock underlying the 2026 Notes, subject to anti-dilution adjustments substantially similar to those applicable to the 2026 Notes. The cost of the Capped Call Transactions was approximately $ 39.9 million. The Capped Call Transactions are separate transactions and are not part of the terms of the 2026 Notes and will not affect any holder’s rights under the notes. Holders of the 2026 Notes will not have any rights with respect to the Capped Call Transactions. OCEANE Convertible Bonds On May 31, 2018, EOS issued 4,344,651 OCEANEs denominated in Euros, due May 2023 for aggregate gross proceeds of $ 34.3 million (€ 29.5 million). The OCEANEs are unsecured obligations of EOS, rank equally with all other unsecured and unsubordinated obligations of EOS, and pay interest at a rate equal to 6 % per year, payable semiannually in arrears on May 31 and November 30 of each year, beginning November 30, 2018 . Unless either earlier converted or repurchased, the OCEANEs will mature on May 31, 2023 . Interest expense w as $ 0.2 million for the three months ended March 31, 2023 and 2022. In connection with the public tender offer to acquire EOS, the Company purchased 2,486,135 OCEANEs, and as such, 1,858,516 OCEANEs with a principal amount of $ 15.3 million (€ 12.6 million) remained outstanding at the time of acquisition. The OCEANEs are convertible by their holders into new EOS Shares or exchangeable for existing EOS Shares, at the Company’s option, at an initial conversion rate of one share per OCEANE, and the initial conversion rate is subject to customary anti-dilution adjustments. The OCEANEs are convertible at any time until the seventh business day prior to maturity or seventh business day prior to an earlier redemption of the OCEANE. If the number of shares calculated is not a whole number, the holder may request allocation of either the whole number of shares immediately below the number and receive an amount in cash equal to the remaining fractional share value, or the whole number of shares immediately above the number and pay an amount in cash equal to the remaining fractional share value. Holders of the OCEANEs have the option to convert all or any portion of such OCEANEs, regardless of any conditions, at any time until the close of seventh business day immediately preceding the maturity date. EOS has a right to redeem all of the OCEANEs at its option any time at a cash redemption price equal to the par value of the OCEANEs plus accrued and unpaid interest if the product of the volume-weighted-average price of the shares and the conversion ratio as specified in the agreement in effect on each trading day exceeds 150 % of the par value of each OCEANE on each of at least twenty consecutive trading days during any forty consecutive trading days, if EOS redeems the OCEANEs when the number of OCEANEs outstanding is 15 % or less of the number of OCEANEs originally issued, or the occurrence of a tender or exchange offer. As a result of the Company’s acquisition of EOS, the OCEANEs are now convertible into new shares of EOS, as a wholly-owned subsidiary of the Company. OCEANE holders can redeem the notes upon the occurrence of an event of default or upon the occurrence of a change of control. In July 2021, in connection with the change of control, holders of 25,971 OCEANEs chose to redeem their bonds for approximately $ 0.2 million (€ 0.2 million). The carrying value of the outstanding OCEANEs was $ 13.6 million (€ 12.5 million) as of March 31, 2023. Other Debt Agreements In January and April 2021, prior to the acquisition, EOS obtained two loan agreements, denominated in Euros, under French government sponsored COVID-19 relief initiatives (pret garanti par l’etat or “PGE” loans). Each PGE loan contains a 12 -month term and 90 % of the principal balance of each loan is state guaranteed. The cost of the state guaranty is 0.25 % of the loan amounts. The loans carry an interest-free rate from the commercial banks (€ 3.3 million) and a 1.75 % interest rate from the lender (€ 1.5 million). The loan capital and loan guaranty costs are payable in full at the end of the 12-month term or the loan may be extended up to 5 additional years. If the Company chooses to extend the debt, the election must be made by the Company between months 8 and 11 of the 12-month term. The extension will carry an interest rate at the banks’ refinancing cost, to be applied from year 2 to year 6 and an increased state guaranty cost (50 to 200 bps, as per a scale with company size and extension year). In February 2022, the Company extended the maturity for each loan agreement to 2027 . Each loan has a 12 -month period from the applicable extension date where interest only payments will occur (the “Interest Only Period”). Following the Interest Only Period, monthly and quarterly installments of principal and interest under each loan agreement will be due until the original principal amounts and applicable interest is fully repaid in 2027. The outstanding obligation under each loan as of March 31, 2023 was $ 3.6 million and $ 1.6 million (€ 3.3 million and € 1.5 million) at weighted average interest rates of 0.98 % and 1.25 %, respectively, and weighted average costs of the state guaranty of 0.69 % and 1.00 %, respectively. Total Indebtedness Principal payments remaining on the Company's debt are as follows as of March 31, 2023 (in thousands): Remainder of 2023 $ 15,694 2024 1,752 2025 1,714 2026 317,534 2027 8,762 Thereafter 103,250 Total 448,706 Less: unamortized debt discount and debt issuance costs ( 13,183 ) Total 435,523 Less: current portion of long-term debt ( 16,068 ) Long-term debt $ 419,455

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	8. Commitments and Contingencies Leases The Company determines if an arrangement is a lease at inception by assessing whether there is an identified asset and whether the contract conveys the right to control the use of the identified asset in exchange for consideration over a period of time. If both criteria are met, the Company records the associated lease liability and corresponding right-of-use asset (“ROU asset”) upon commencement of the lease using a discount rate based on the incremental borrowing rate of interest that the Company would borrow on a collateralized basis for an amount equal to the lease payments in a similar economic environment. Any short-term leases defined as twelve months or less or month-to-month leases are excluded and are expensed each month. Total costs associated with these short-term leases are immaterial to all periods presented. The Company leases office and storage facilities and equipment under various operating and financing lease agreements. The initial terms of these leases range from 1 to 10 years and generally provide for periodic rent increases. The Company’s lease agreements do not contain any material variable lease payments, residual value guarantees or material restrictive covenants. The Company aggregates all lease and non-lease components for each class of underlying assets into a single lease component and variable charges for common area maintenance and other variable costs are recognized as expense as incurred. Total variable costs associated with leases for the three months ended March 31, 2023 were immaterial. The Company had an immaterial amount of financing leases as of March 31, 2023, which is included in property and equipment, net, accrued expenses and other current liabilities, and other long-term liabilities, on the condensed consolidated balance sheets. The Company occupies 121,541 square feet of office space as its headquarters in Carlsbad, California. On December 4, 2019, the Company entered into a 10 -year operating lease that commenced on February 1, 2021 and will terminate on January 31, 2031 , subject to two sixty-month options to renew which are not reasonably certain to be exercised. Base rent under the building lease increases annually by 3 % throughout the remainder of the lease. On May 11, 2022, the Company entered into a lease amendment for the buildout of additional space within the building which resulted in a lease modification increasing the ROU asset and lease liability. Future minimum annual lease payments for all operating leases of the Company are as follows as of March 31, 2023 (in thousands): Remainder of 2023 $ 3,739 2024 5,039 2025 5,024 2026 5,085 2027 5,127 Thereafter 13,080 Total undiscounted lease payments 37,094 Less: imputed interest ( 6,391 ) Operating lease liabilities 30,703 Less: current portion of operating lease liabilities ( 4,796 ) Operating lease liabilities, less current portion $ 25,907 The Company’s weighted average remaining lease term and weighted average discount rate as of March 31, 2023 and December 31, 2022 are as follows: March 31, December 31, Weighted-average remaining lease term (years) 7.3 7.7 Weighted-average discount rate 5.5 % 5.5 % Information related to the Company’s operating leases is as follows (in thousands): Three Months Ended 2023 2022 Rent expense $ 1,244 $ 1,156 Cash paid for amounts included in measurement of lease liabilities $ 4,366 $ 1,022 Purchase Commitments The Company is obligated to meet certain minimum purchase commitment requirements with a third-party supplier through December 2026. As of March 31, 2023, the remaining minimum purchase commitment required by the Company under the agreement is $ 26.4 million. Litigation The Company is and may become involved in various legal proceedings arising from its business activities. While management is not aware of any litigation matter that in and of itself would have a material adverse impact on the Company’s condensed consolidated results of operations, cash flows or financial position, litigation is inherently unpredictable, and depending on the nature and timing of a proceeding, an unfavorable resolution could materially affect the Company’s future consolidated results of operations, cash flows or financial position in a particular period. The Company assesses contingencies to determine the degree of probability and range of possible loss for potential accrual or disclosure in the Company’s condensed consolidated financial statements. An estimated loss contingency is accrued in the Company’s condensed consolidated financial statements if it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Because litigation is inherently unpredictable and unfavorable resolutions could occur, assessing contingencies is highly subjective and requires judgments about future events. When evaluating contingencies, the Company may be unable to provide a meaningful estimate due to a number of factors, including the procedural status of the matter in question, the presence of complex or novel legal theories, and/or the ongoing discovery and development of information important to the matters. In addition, damage amounts claimed in litigation against the Company may be unsupported, exaggerated or unrelated to reasonably possible outcomes, and as such are not meaningful indicators of the Company’s potential liability. Indemnifications In the normal course of business, the Company enters into agreements under which it occasionally indemnifies third-parties for intellectual property infringement claims or claims arising from breaches of representations or warranties. In addition, from time to time, the Company provides indemnity protection to third-parties for claims relating to past performance arising from undisclosed liabilities, product liabilities, environmental obligations, representations and warranties, and other claims. In these agreements, the scope and amount of remedy, or the period in which claims can be made, may be limited. It is not possible to determine the maximum potential amount of future payments, if any, due under these indemnities due to the conditional nature of the obligations and the unique facts and circumstances involved in each agreement. In October 2017, NuVasive filed a lawsuit in Delaware Chancery Court against Mr. Miles, the Company’s Chairman and CEO, who was a former officer and board member of NuVasive. The Company itself was not initially a named defendant in this lawsuit; however, in June 2018, NuVasive amended its complaint to add the Company as a defendant. In October 2018, the Delaware Court ordered that NuVasive advance legal fees for Mr. Miles’ defense in the lawsuit, as well as Mr. Miles’ legal fees incurred in pursuing advancement of his fees, pursuant to an indemnification agreement between NuVasive and Mr. Miles. As of March 31, 2023, the Company has not recorded any liability on the condensed consolidated balance sheet related to this matter. Royalties The Company has entered into various intellectual property agreements requiring the payment of royalties based on the sale of products that utilize such intellectual property. These royalties primarily relate to products sold by Alphatec Spine and are based on fixed fees or calculated either as a percentage of net sales or on a per-unit sold basis. Royalties are included on the accompanying condensed consolidated statements of operations as a component of cost of sales.

Earnings Per Share [Abstract]
Net Loss Per Share	11. Net Loss Per Share Basic net loss per share is calculated by dividing the net loss available to common stockholders by the weighted-average number of common shares outstanding for the period. If applicable, diluted net loss per share attributable to common stockholders is calculated by dividing net loss available to common stockholders by the diluted weighted-average number of common shares outstanding for the period, determined using the treasury-stock method and the if-converted method for convertible debt. For purposes of this calculation, common stock subject to repurchase by the Company, common stock issuable upon conversion or exercise of convertible notes, preferred shares, options, and warrants are considered to be common stock equivalents and are only included in the calculation of diluted earnings per share when their effect is dilutive. Due to the Company’s net loss position, the effect of including common stock equivalents in the earnings per share calculation is anti-dilutive, and therefore not included. The following table presents the computation of basic and diluted net loss per share (in thousands, except per share amounts): Three Months Ended 2023 2022 Numerator: Net loss $ ( 43,529 ) $ ( 42,616 ) Denominator: Weighted average common shares outstanding 109,751 99,978 Net loss per share, basic and diluted: $ ( 0.40 ) $ ( 0.43 ) The following potentially dilutive shares of common stock were excluded from the calculation of diluted net loss per share because their effect would have been anti-dilutive for the periods presented (in thousands): As of 2023 2022 Series A convertible preferred stock — 29 Options to purchase common stock and employee stock purchase plan 2,706 3,435 Unvested restricted stock unit awards 7,037 9,781 Warrants to purchase common stock 9,654 19,654 Senior convertible notes 17,246 17,246 Total 36,643 50,145

Income Taxes	12. Income Taxes To calculate its interim tax provision, at the end of each interim period the Company estimates the annual effective tax rate, adjusted for discrete items arising in that quarter. The computation of the annual estimated effective tax rate at each interim period requires certain estimates and significant judgment including, but not limited to, the estimated annual taxable income or loss for the year and projections of the proportion of income earned and taxed in foreign jurisdictions. The accounting estimates used to compute the provision for income taxes may change as new events occur, additional information is obtained, or the tax environment changes. The Company’s effective tax rate from continuing operations wa s ( 0.03 %) and 0.23 % for the three months ended March 31, 2023 and 2022 , respectively. The Company’s effective tax rate differs from the federal statutory rate of 21 % in each period primarily due to the Company’s net loss position and valuation allowance.

Accounting Policies [Abstract]
The Company	The Company Alphatec Holdings, Inc. (the “Company”), through its wholly owned subsidiaries, Alphatec Spine, Inc. (“Alphatec Spine”), SafeOp Surgical, Inc. (“SafeOp”), and EOS imaging S.A. (“EOS”), is a medical technology company that designs, develops, and markets technology for the treatment of spinal disorders associated with disease and degeneration, congenital deformities, and trauma. The Company markets its products in the United States of America and internationally via a network of independent sales agents and direct sales representatives.
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. The Company translates the financial statements of its foreign subsidiaries using end-of-period exchange rates for assets and liabilities and average exchange rates during each reporting period for results of operations. All intercompany balances and transactions have been eliminated during consolidation. The accompanying condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Pursuant to these rules and regulations, the Company has condensed or omitted certain information and footnotes it normally includes in its annual consolidated financial statements prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”). The unaudited interim condensed consolidated financial statements reflect all adjustments, including normal recurring adjustments which, in the opinion of management, are necessary for a fair statement of the financial position and results of operations for the periods presented. These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements for the year ended December 31, 2022, which are included in the Company’s Annual Report on Form 10-K that was filed with the SEC. Operating results for the three months ended March 31, 2023 are not necessarily indicative of the results that may be expected for the year ending December 31, 2023, or any other future periods.
Prior-period Adjustment	Prior-period Adjustment Subsequent to the issuance of the Company’s consolidated financial statements as of and for the year ended December 31, 2022, the Company identified that a deferred tax liability and additional goodwill related to the acquisition of EOS should have been recorded at the time of the acquisition. The Company corrected the errors in the accompanying condensed consolidated financial statements as of the earliest period presented and has concluded that the correction of these errors is not material to the previously issued financial statements. The correction to the accompanying unaudited condensed consolidated balance sheets, condensed consolidated statements of operations, condensed consolidated statements of comprehensive loss, condensed consolidated statements of stockholder's equity, and condensed consolidated statements of cash flows are as follows (in thousands): At December 31, 2021 Condensed Consolidated Statements of Stockholder's Equity As Reported Adjustment As Corrected Accumulated other comprehensive loss $ ( 5,994 ) $ ( 42 ) $ ( 6,036 ) Accumulated deficit ( 782,325 ) 1,294 ( 781,031 ) Total stockholder's equity $ 79,422 $ 1,252 $ 80,674 At December 31, 2022 Condensed Consolidated Balance Sheets As Reported Adjustment As Corrected Goodwill $ 39,775 $ 7,592 $ 47,367 Total Assets 513,376 7,592 520,968 Other long-term liabilities 11,543 5,546 17,089 Accumulated other comprehensive deficit ( 10,690 ) ( 104 ) ( 10,794 ) Accumulated deficit ( 934,474 ) 2,150 ( 932,324 ) Total stockholder's deficit ( 36,713 ) 2,046 ( 34,667 ) Total liabilities and stockholders' deficit $ 513,376 $ 7,592 $ 520,968 Three Months Ended March 31, 2022 Condensed Consolidated Statements of Operations As Reported Adjustment As Corrected Income tax provision (benefit) $ 129 $ ( 228 ) $ ( 99 ) Net loss $ ( 42,844 ) $ 228 $ ( 42,616 ) Three Months Ended March 31, 2022 Condensed Consolidated Statements of Comprehensive Loss As Reported Adjustment As Corrected Net loss $ ( 42,844 ) $ 228 $ ( 42,616 ) Foreign currency translation adjustments ( 1,180 ) ( 24 ) ( 1,204 ) Comprehensive loss $ ( 44,024 ) $ 204 $ ( 43,820 ) Three Months Ended March 31, 2022 Condensed Consolidated Statements of Stockholder's Equity As Reported Adjustment As Corrected Foreign currency translation adjustments $ ( 1,180 ) $ ( 24 ) $ ( 1,204 ) Net loss ( 42,844 ) 228 ( 42,616 ) Total stockholder's equity $ 41,984 $ 1,456 $ 43,440 Three Months Ended March 31, 2022 Condensed Consolidated Statements of Cash Flows As Reported Adjustment As Corrected Net loss $ ( 42,844 ) $ 228 $ ( 42,616 ) Other long-term liabilities ( 716 ) ( 221 ) ( 937 ) Net cash used for operating activities ( 24,712 ) 7 ( 24,705 ) Effect of exchange rate changes on cash $ ( 14 ) $ ( 7 ) $ ( 21 )
Reclassification	Reclassification Certain financial statement line items in the condensed consolidated financial statements for the three months ended March 31, 2022 have been disaggregated into multiple financial statement line items to conform to the current year’s presentation.
Use of Estimates	Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of revenues and expenses. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include the useful lives of property and equipment, goodwill, intangible assets, allowances for doubtful accounts, deferred tax assets, inventory, stock-based compensation, revenues, income tax uncertainties, and other contingencies.
Fair Value Measurements	Fair Value Measurements The carrying amount of financial instruments consisting of cash and cash equivalents, accounts receivable, prepaid expenses and other current assets, accounts payable, accrued expenses, and short-term debt included in the Company’s condensed consolidated financial statements are reasonable estimates of fair value due to their short maturities. Authoritative guidance establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: Level 1: Quoted prices in active markets for identical assets or liabilities. Level 2: Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active; or other inputs that can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3: Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
Excess and Obsolete Inventory	Excess and Obsolete Inventory Most of the Company’s inventory is comprised of finished goods, which is primarily produced by third-party suppliers. Specialized implants, fixation products, biologics, and disposables are determined by utilizing a standard cost method that includes capitalized variances which approximates the weighted average cost. Imaging equipment and related parts are valued at weighted average cost. Inventories are stated at the lower of cost or net realizable value. The Company reviews the components of its inventory on a periodic basis for excess and obsolescence and adjusts inventory to its net realizable value as necessary. The Company records a lower of cost or net realizable value (“LCNRV”) inventory reserve for estimated excess and obsolete inventory based upon its expected use of inventory on hand. The Company’s inventory, which consists primarily of specialized implants, fixation products, biologics, and disposables is at risk of obsolescence due to the need to maintain substantial levels of inventory. In order to market its products effectively and meet the demands of interoperative product placement, the Company maintains and provides surgeons and hospitals with a variety of inventory products and sizes. For each surgery, fewer than all components will be consumed. The need to maintain and provide a wide variety of inventory causes inventory to be held that is not likely to be used. The Company’s estimates and assumptions for excess and obsolete inventory are reviewed and updated on a quarterly basis. The estimates and assumptions are determined primarily based on current usage of inventory and the age of inventory quantities on hand. Additionally, the Company considers recent sales experience to develop assumptions about future demand for its products, while considering product life cycles and new product launches. Increases in the LCNRV reserve for excess and obsolete inventory result in a corresponding charge to cost of sales.
Revenue Recognition	Revenue Recognition The Company recognizes revenue from product sales in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Revenue from Contracts with Customers (“Topic 606”). This standard applies to all contracts with customers, except for contracts that are within the scope of other standards, such as leases, insurance, collaboration arrangements, and financial instruments. Under Topic 606, an entity recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration that the entity expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of Topic 606, the entity performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. The Company only applies the five-step model to contracts when it is probable that the entity will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. Sales are derived primarily from the sale of spinal implant products, imaging equipment, and related services to hospitals and medical centers through direct sales representatives and independent sales agents. Revenue is recognized when obligations under the terms of a contract with customers are satisfied, which occurs with the transfer of control of products to customers, either upon shipment of the product or delivery of the product to the customer depending on the shipping terms, or when the products are used in a surgical procedure (implanted in a patient). Revenue from the sale of imaging equipment is recognized as each distinct performance obligation is fulfilled and control transfers to the customer, beginning with shipment or delivery, depending on the terms. Revenue from other distinct performance obligations, such as maintenance on imaging equipment and other imaging-related services, is recognized in the period the service is performed, and makes up less than 10 % of the Company’s total revenue. Revenue is measured based on the amount of consideration expected to be received in exchange for the transfer of the goods or services specified in the contract with each customer. In certain cases, the Company does offer the ability for customers to lease its imaging equipment primarily on a non-sales type basis, but such arrangements are immaterial to total revenue in the periods presented. The Company generally does not allow returns of products that have been delivered. Costs incurred by the Company associated with sales contracts with customers are deferred over the performance obligation period and recognized in the same period as the related revenue, except for contracts that complete within one year or less, in which case the associated costs are expensed as incurred. Payment terms for sales to customers may vary but are commensurate with the general business practices in the country of sale. To the extent that the transaction price includes variable consideration, such as discounts, rebates, and customer payment penalties, the Company estimates the amount of variable consideration that should be included in the transaction price utilizing either the expected value method or the most likely amount method depending on the nature of the variable consideration. Variable consideration is included in the transaction price if, in the Company's judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur. Estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of the Company’s anticipated performance and all information that is reasonably available, including historical, current, and forecasted information. The Company records a contract liability, or deferred revenue, when it has an obligation to provide a product or service to the customer and payment is received in advance of its performance. When the Company sells a product or service with a future performance obligation, revenue is deferred on the unfulfilled performance obligation and recognized over the related performance period. Generally, the Company does not have observable evidence of the standalone selling price related to its future service obligations; therefore, the Company estimates the selling price using an expected cost plus a margin approach. The transaction price is allocated using the relative standalone selling price method. The use of alternative estimates could result in a different amount of revenue deferral.
Recently Adopted and Issued Accounting Pronouncements	Recently Adopted and Issued Accounting Pronouncements In August 2021, the FASB issued Accounting Standards Update ("ASU") No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers . The guidance requires application of Topic 606, Revenue from Contracts with Customers to recognize and measure contract assets and contract liabilities acquired in a business combination. ASU No. 2021-08 adds an exception to the general recognition and measurement principle in Topic 805 where assets acquired and liabilities assumed in a business combination, including contract assets and contract liabilities arising from contracts with customers, are measured at fair value on the acquisition date. Under the new guidance, the acquirer will recognize acquired contract assets and contract liabilities as if the acquirer had originated the contract. The standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022, with early adoption permitted. The Company adopted ASU No. 2021-08 as of January 1, 2023, on a prospective basis. The adoption of ASU No. 2021-08 did not have a material impact on the Company's condensed consolidated financial statements and related disclosures.
