NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

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.S. (“EOS”), is a medical technology company focused on the design, development, and advancement of technology for the better surgical treatment of spinal disorders. The Company, headquartered in Carlsbad, California, markets its products in the United States 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, 2023, which are included in the Company’s Annual Report on Form 10-K that was filed with the SEC. Operating results for the six months ended June 30, 2024 are not necessarily indicative of the results that may be expected for the year ending December 31, 2024, or any other future periods.

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, inventories, 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.

Table of Contents

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, and biologics are valued by utilizing a standard cost method that includes capitalized variances which together 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. 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 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.

Table of Contents

The Company records a contract asset when one or more performance obligations have been completed by the Company and revenue has been recognized, but the customer's payment is contingent on the satisfaction of additional performance obligations. Contract assets are generally short-term in nature. 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. These amounts primarily relate to undelivered equipment and related services, or maintenance agreements. 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 Issued Accounting Pronouncements

In December 2023, the FASB issued Accounting Standard Update ("ASU") No. 2023-09, Income Taxes (Topic 740): Improvement to Income Tax Disclosures to enhance the transparency of income tax disclosures. The guidance in ASU No. 2023-09 allows for a prospective method of transition, with the option to apply the standard retrospectively.

8. 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. On September 28, 2023, the Company drew an additional $50.0 million (the “delayed draw term loan(s)” or the “DDTL”). The Braidwell Term Loan matures on January 6, 2028. As of June 30, 2024, the outstanding balance under the Braidwell Term Loan was $150.0 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 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 June 30, 2024, debt issuance costs and debt discount, net of accumulated amortization, associated with the Braidwell Term Loan were $2.7 million and $1.1 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 June 30, 2024 was 11.2%. 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 2.0% 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 June 30, 2024 was 12.2%. During the three months ended June 30, 2024, the Company recognized interest expense on the Braidwell Term Loan of $4.3 million, which includes $0.2 million for the amortization of debt issuance costs and $0.1 million for the debt discount. During the six months ended June 30, 2024, the Company recognized interest expense on the Braidwell Term Loan of $8.5 million, which includes $0.3 million for the amortization of debt issuance costs and $0.2 million for the debt discount. During the three months ended June 30, 2023, the Company recognized interest expense on the Braidwell Term Loan of $2.9 million, which includes $0.1 million for the amortization of debt issuance costs and $0.1 million for the debt discount. During the six months ended June 30, 2023, the Company recognized interest expense on the Braidwell Term Loan of $5.6 million, which includes $0.2 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.

Table of Contents

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 June 30, 2024.

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 increases up to $25.0 million in the Revolving Credit Facility for a total commitment of up to $75.0 million. The Company subsequently increased the borrowing capacity by $5.0 million for a total borrowing capacity of $55.0 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 June 30, 2024, the outstanding balance under the Revolving Credit Facility was $54.9 million.

In conjunction with obtaining the Revolving Credit Facility, the Company incurred $1.4 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 June 30, 2024, debt issuance costs, net of accumulated amortization, associated with the Revolving Credit Facility were $0.9 million.

The outstanding loans under the Revolving Credit Facility bear interest at the sum of Term SOFR plus 3.5% per annum. The applicable interest rate as of June 30, 2024 was 8.9%. 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 $0.8 million and $1.1 million during the three and six months ended June 30, 2024, respectively, which includes approximately $0.1 million for the amortization of debt issuance costs for both periods. The Company recognized interest expense on the Revolving Credit Facility of $0.3 million and $0.8 million during the three and six months ended June 30, 2023, respectively, which includes approximately $0.1 million for the amortization of debt issuance costs for both periods. 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 June 30, 2024, 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 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 June 30, 2024.

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. The 2026 Notes do not contain any financial covenants.

Table of Contents

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 June 30, 2024, 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 June 30, 2024.

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 and $2.2 million, respectively, during the three and six months ended June 30, 2024, which includes $0.5 million and $1.0 million for the amortization of debt issuance costs, respectively. The Company recognized interest expense on the 2026 Notes of $1.1 million and $2.1 million, respectively, during the three and six months ended June 30, 2023, which includes $0.5 million and $1.0 million for the amortization of debt issuance costs, respectively. 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):


	June 30, 2024			December 31, 2023

Table of Contents

Capped Call Transactions

In connection with the offering of the 2026 Notes, the Company entered into privately negotiated capped call transactions (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 2026 Notes. Holders of the 2026 Notes will not have any rights with respect to the Capped Call Transactions.

Other Debt Agreements

The Company has two loan agreements under French government sponsored COVID-19 relief initiatives (“PGE” loans) which mature in 2027. Monthly and quarterly installments of principal and interest under each PGE loan agreement is due until the original principal amounts and applicable interest is fully repaid in 2027. The outstanding obligation under each PGE loan as of June 30, 2024 was $2.8 million and $1.2 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.

9. 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 and six months ended June 30, 2024 were immaterial. The Company had an immaterial amount of financing leases as of June 30, 2024, 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.

Purchase Commitments

The Company is obligated to meet certain minimum purchase commitment requirements with a third-party supplier through December 2026. As of June 30, 2024, the remaining minimum purchase commitment required by the Company under the agreement is $9.8 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 June 30, 2024, the Company has not recorded any liability on the condensed consolidated balance sheets 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.

10. Stock-Benefit Plans and Equity Transactions

Stock-Based Compensation

The Company has stock-based compensation plans under which it grants stock options, restricted stock units ("RSUs"), and performance restricted stock units ("PRSUs") to officers, directors and third parties. Total stock-based compensation for the periods presented are as follows (in thousands):


	Three Months Ended				Six Months Ended
	June 30,				June 30,
	2024		2023		2024		2023
Cost of sales	$	554	$	16,226	$	1,037	$	22,232

The Company has entered into Development Service Agreements for the development of a wide variety of potential products and intellectual property. Under these agreements, future royalty payments for product and/or intellectual property rights may be paid in either cash or restricted shares of the Company’s common stock at the election of the developer, depending on the terms of the agreement. Certain of these agreements were amended to remove the cash royalty option and require settlement in restricted shares of the Company’s common stock. During the three and six months ended June 30, 2024 and 2023, the vesting conditions of certain of these awards were deemed probable. Stock-based compensation associated with these awards is included in cost of sales and research and development expense on the condensed consolidated statements of operations.

Restricted Stock Units and Performance Based Restricted Stock Units Awards

The Company issued approximately 309,000 and 3,473,000 shares of common stock, before net share settlement, upon vesting of RSUs and PRSUs during the three and six months ended June 30, 2024, respectively. The Company issued approximately 2,921,000 and 4,889,000 shares of common stock, before net share settlement, upon vesting of RSUs and PRSUs during the three and six months ended June 30, 2023, respectively.

11. Business Segment and Geographic Information

The Company operates in one segment based upon the Company’s organizational structure, the way in which the operations and investments are managed and evaluated by the chief operating decision maker (“CODM”) as well as the lack of available discrete financial information at a level lower than the consolidated level. The Company shares common, centralized support functions which report directly to the CODM and decision-making regarding the Company’s overall operating performance and allocation of Company resources is assessed on a consolidated basis.

Net revenue and property and equipment, net, by geographic region are as follows (in thousands):

12. 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 June 30,						Six Months Ended June 30,
	2024			2023			2024			2023
Numerator:
Net loss	$	(40,680	)	$	(51,377	)	$	(89,175	)	$	(94,906	)
Denominator:

Net loss per share, basic and diluted:	$	(0.29	)	$	(0.43	)	$	(0.63	)	$	(0.83	)

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):

13. 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 operations was 0.70% and 0.40% for the three and six months ended June 30, 2024, respectively. The Company’s effective tax rate from operations was 0.10% and 0.04% for the three and six months ended June 30, 2023, 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.

14. Related Party Transactions

The Company purchases inventory from an affiliate of Squadron Capital, LLC (the “Squadron Supplier Affiliate”). David Pelizzon, President and Director of Squadron Capital, LLC, currently serves on the Company’s Board of Directors. For the three and six months ended June 30, 2024, the Company purchased inventory in the amounts of $3.2 million and $8.0 million, respectively, from the Squadron Supplier Affiliate. For the three and six months ended June 30, 2023, the Company purchased inventory in the amounts of $4.7 million and $8.3 million, respectively, from the Squadron Supplier Affiliate. As of June 30, 2024, and December 31, 2023, the Company had $7.8 million and $5.4 million, respectively, due to the Squadron Supplier Affiliate, for inventory purchases.

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

You should read the following management's discussion and analysis of our financial condition and results of operations in conjunction with our unaudited condensed consolidated financial statements and the related notes thereto that appear elsewhere in this Quarterly Report on Form 10-Q and the audited consolidated financial statements and notes thereto and under the heading "Management's Discussion and Analysis of Financial Condition and Results of Operations" in our Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”). In addition to historical information, the following management’s discussion and analysis of our financial condition and results of operations includes forward-looking information that involves risks, uncertainties, and assumptions. Our actual results and the timing of events could differ materially from those anticipated by these forward-looking statements as a result of many factors, such as those set forth under “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2023, and any updates to those risk factors filed from time to time in our subsequent periodic and current reports filed with the SEC.

Overview

We are a medical technology company, headquartered in Carlsbad, California, focused on the design, development, and advancement of technology for better surgical treatment of spine disorders. By applying our unique, 100% spine focus and deep, collective industry know-how, we aim to revolutionize the approach to spine surgery through clinical distinction. The sophisticated approaches that we create from the ground up are designed to integrate with our expanding Alpha InformatiX™ product platform to objectively inform surgery and achieve the goals of spine surgery more predictably and more reproducibly. We have a comprehensive product portfolio designed to address the spine’s various pathologies, and are perpetually innovating to accomplish our ultimate vision, which is to be the standard bearer in spine.

The application of our team’s deep spine know-how, coupled with a willingness to invest holistically in the technologies integrated into our procedural approaches continues to increasingly compel surgeons and sales talent to partner with us. That adoption-driven validation has been the source of industry-leading market share expansion, which has delivered an approximately 40% revenue compound annual growth rate since our transformation commenced in 2018.

We market and sell our products through a network of independent sales agents and direct sales representatives. To deliver consistent, predictable growth, we have added, and intend to continue to add, clinically astute and exclusive sales team members to reach untapped surgeons, hospitals, and national accounts and better penetrate existing accounts and territories.

Revenue and Expense Components

The following is a description of the primary components of our revenue and expenses:

Revenue. We derive our revenue primarily from the sale of spinal surgery implants used in the treatment of spine disorders as well as the sale of medical imaging equipment which is used for surgical planning and post-operative assessment. Spinal implant products include pedicle screws and complementary implants, interbody devices, plates, and tissue-based materials. Medical imaging equipment includes our EOS full-body and weight-bearing x-ray imaging devices, and related services. Our revenue is generated by our direct sales force and independent sales agents. Our products are shipped and invoiced to hospitals and surgical centers. Currently, most of our business is conducted with customers within markets in which we have experience and with payment terms that are customary to our business. We may defer revenue until the time of collection if circumstances related to payment terms, regional market risk or customer history indicate that collectability is not certain.

Cost of sales. Cost of sales consists primarily of direct product costs, royalties, service labor hours, and parts. Our product costs consist primarily of raw materials, component parts, direct labor, and overhead. The product costs of certain of our biologics products include the cost of procuring and processing human tissue. We incur royalties related to the technologies that we license from others and the products that are developed in part by surgeons with whom we collaborate in the product development process.

Table of Contents

Research and development expenses. Research and development expenses consist of costs associated with the design, development, testing, and enhancement of our products. Research and development expenses also include salaries and related employee benefits, research-related overhead expenses, and fees paid to external service providers and development consultants in the form of both cash and equity.

Sales, general and administrative expenses. Sales, general and administrative expenses consist primarily of salaries and related employee benefits, sales commissions and other variable costs, depreciation of our surgical instruments, regulatory affairs, quality assurance costs, professional service fees, travel, medical education, trade show and marketing costs, and insurance expenses.

Litigation-related expenses. Litigation-related expenses consist of costs incurred for our ongoing and settled litigation.

Amortization of acquired intangible assets. Amortization of acquired intangible assets consists of intangible assets acquired in business combinations and asset acquisitions.

Transaction-related expenses. Transaction-related expenses consist of one-time costs associated with business combinations and asset acquisitions. These items may include but are not limited to consulting and legal fees, and other related deal costs.

Restructuring expenses. Restructuring expenses are primarily associated with the realignment of our operations and geographical footprint to achieve synergies, in which we incur one-time costs related to exiting and/or relocating our facilities, and personnel related expenses including severance and other costs.

Total interest expense and other expense, net. Total interest expense and other expense, net includes interest income, interest expense, gains and losses from foreign currency exchanges and other non-operating gains and losses.

Income tax provision. Income tax provision primarily consists of an estimate of federal, state, and foreign income taxes based on enacted state and foreign tax rates, as adjusted for allowable credits, deductions, uncertain tax positions, changes in the valuation of our deferred tax assets and liabilities, and changes in tax laws.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations is based upon our unaudited condensed consolidated financial statements, which have been prepared in accordance with generally accepted accounting principles in the United States of America. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses, and related disclosures. On an on-going basis, we evaluate our estimates and assumptions, including those related to revenue recognition, allowances for accounts receivable, inventories, intangible assets, stock-based compensation, and income taxes. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumption conditions.

Critical accounting policies are those that, in management’s view, are most important in the portrayal of our financial condition and results of operations. Management believes there have been no material changes during the three months ended June 30, 2024, to the critical accounting policies discussed in the Management’s Discussion and Analysis of Financial Condition and Results of Operations section of our Annual Report on Form 10-K for the year ended December 31, 2023, filed with the SEC.

Revenue from products and services increased $28.6 million, or 25%, and $58.0 million, or 26%, during the three and six months ended June 30, 2024, respectively, compared to the same period in 2023. The increase was primarily due to an increase in product volume that was due to the increase in our surgeon user base, continued expansion of our new product portfolio, and increasing adoption of our technology.

Cost of sales decreased $9.4 million, or 18%, and $7.0 million, or 8%, for the three and six months ended June 30, 2024, respectively, compared to the same period in 2023. The decrease was primarily due to a decrease in stock-based compensation offset by an increase in product volume. We have entered into Development Service Agreements for the development of a wide variety of potential products and intellectual property. Under these agreements, future royalty payments for product and/or intellectual property rights may be paid in either cash or restricted shares of our common stock at the election of the developer, depending on the terms of the agreement. Certain of these agreements were amended to remove the cash royalty option and require settlement in restricted shares of our common stock. During the three and six months ended June 30, 2023, the vesting conditions of certain of these amended awards were deemed probable. There were no such vesting conditions met during the three and six months ended June 30, 2024 resulting in a decrease in stock-based compensation for the period.

Research and development expenses. Research and development expenses increased $4.5 million, or 31%, and $9.3 million, or 33%, for the three and six months ended June 30, 2024, respectively, compared to the same period in 2023. The increase was primarily due to an increase in personnel to support the expansion of our new product portfolio.

Sales, general and administrative expenses. Sales, general and administrative expenses increased $25.4 million, or 29%, and $47.9 million, or 27%, during the three and six months ended June 30, 2024, respectively, compared to the same period in 2023. The increase was primarily due to higher compensation-related costs and variable selling expenses associated with the increase in revenue, and our continued investment in building our strategic distribution channel. Additionally, we continued to increase our investment in our sales and marketing functions by increasing headcount to support the growth of our business, as well as necessary administrative support.

Litigation-related expenses. Litigation expenses decreased $4.8 million, or 70%, and $3.6 million, or 35%, for the three and six months ended June 30, 2024, respectively, compared to the same period in 2023. The decrease was primarily related to settled litigation matters.

Amortization of acquired intangible assets. Amortization expense increased $1.1 million, or 17%, during the six months ended June 30, 2024, compared to the same period in 2023. The increase in amortization of acquired intangible assets is primarily due to amortization of intangible assets acquired in the acquisition of the navigation-enabled robotics platform ("Valence") in April 2023.

Transaction-related expenses. Transaction-related expense decreased $1.9 million, or 100%, and $2.0 million, or 106%, during the three and six months ended June 30, 2024, respectively, compared to the same period in 2023. The decrease in transaction-related expenses is due to the Valence acquisition in April 2023.

Restructuring expenses. The increase in restructuring expenses for the three and six months ended June 30, 2024 is primarily due to costs associated with the relocation of office facilities in Paris, France.

Interest expense, net, increased $1.9 million, or 49%, and $3.4 million, or 44%, during the three and six months ended June 30, 2024, respectively, compared to the same period in 2023. The increase in interest expense, net, was primarily due to drawing an additional $50.0 million on the Braidwell Term Loan in September 2023 and higher interest rates related to our Revolving Credit Facility and Braidwell Term Loan.

Other income, net, decreased $2.2 million, or 93%, and $2.8 million, or 91%, during the three and six months ended June 30, 2024, respectively, compared to the same period in 2023. The change in other income, net, was primarily due to an employee retention credit received during the three months ended June 30, 2023.

The change in the income tax provision for the three and six months ended June 30, 2024, respectively, compared to the same period in 2023, was primarily related to the recognition of income tax benefits in several jurisdictions.

Liquidity and Capital Resources

Our principal sources of liquidity are our existing cash and cash equivalents, our Revolving Credit Facility and cash from operations. Our liquidity and capital structure are evaluated regularly within the context of our annual operating and strategic planning process. We consider the liquidity necessary to fund our operations, which includes working capital needs, investments in research and development, investments in inventory and instrument sets to support our customers, as well as other operating costs. Our future capital requirements will depend on many factors including our rate of revenue growth, the timing and extent of spending to support development efforts, the expansion of sales, marketing and administrative activities, the timing of introductions of new products and enhancements to existing products, and the international expansions of our business.

As current borrowing sources become due, we may be required to access the capital markets for additional funding. If we are required to access the debt markets, we expect to be able to secure reasonable borrowing rates. As part of our liquidity strategy, we will continue to monitor our current level of spending and cash use as well as our ability to secure additional credit facilities, term loans, or other similar arrangements in light of our spending levels and general financial market conditions.

A substantial portion of our operations are in the United States ("U.S."), and most of our net sales have been made in the U.S. Accordingly, we do not have material exposures to foreign currency rate fluctuations from operations. However, as our business in markets outside of the U.S. continues to increase, we will be exposed to foreign currency exchange risk related to our foreign operations.

Table of Contents

We do not have any material financial exposure to one customer or one country that would significantly hinder our liquidity. We are and may become involved in various legal proceedings arising from our business activities. While we have no material, undisclosed accruals for pending litigation or claims, litigation is inherently unpredictable, and depending on the nature and timing of a proceeding, an unfavorable resolution could materially affect our future consolidated results of operations, cash flows or financial position in a particular period. We assess contingencies to determine the degree of probability and range of possible loss for potential accrual or disclosure in our condensed consolidated financial statements. An estimated loss contingency is accrued in our condensed consolidated financial statements if it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Assessing contingencies is highly subjective and requires judgments about future events because litigation is inherently unpredictable, and unfavorable resolutions could occur. When evaluating contingencies, we 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 us may be unsupported, exaggerated, or unrelated to reasonably possible outcomes, and as such are not meaningful indicators of our potential liability. We have disclosed all material accruals for pending litigation or investigations in Note 9, Commitments and Contingencies, in the Notes to Condensed Consolidated Financial Statements included in this Quarterly Report on Form 10-Q.

Cash and cash equivalents were $99.8 million and $221.0 million at June 30, 2024, and December 31, 2023, respectively. We believe that our existing funds, cash generated from our operations and our existing sources of and access to financing are adequate to satisfy our needs for working capital, capital expenditure and debt service requirements, and other business initiatives we plan to strategically pursue.

They can be affected by inaccurate assumptions and/or by known or unknown risks and uncertainties. Many factors mentioned in our discussion in this Quarterly Report on Form 10-Q will be important in determining future results. Consequently, no forward-looking statement can be guaranteed. Actual future results may vary materially from expected results.

We also provide a cautionary discussion of risks and uncertainties under “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2023, and any updates to those risk factors filed from time to time in our subsequent periodic and current reports filed with the SEC.

There are a number of factors and uncertainties that could cause actual events or results to differ materially from those indicated by such forward-looking statements, many of which are beyond our control, including the factors set forth under “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2023 and any updates to those risk factors filed from time to time in our subsequent periodic and current reports filed with the SEC. In addition, the forward-looking statements contained herein represent our estimate only as of the date of this filing and should not be relied upon as representing our estimate as of any subsequent date. While we may elect to update these forward-looking statements at some point in the future, we specifically disclaim any obligation to do so to reflect actual results, changes in assumptions or changes in other factors affecting such forward-looking statements.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Item 4. Controls and Procedures

Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our reports under the Securities Exchange Act of 1934, as amended, or the Exchange Act, is recorded, processed, summarized and reported within the time lines specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can only provide reasonable assurance of achieving the desired control objectives, and in reaching a reasonable level of assurance, management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, we carried out an evaluation of the effectiveness of our disclosure controls and procedures (as defined in SEC Rules 13a - 15(e) and 15d - 15(e)) as of June 30, 2024. Based on such evaluation, our management has concluded that as of June 30, 2024, our disclosure controls and procedures are effective.

Changes in Internal Control over Financial Reporting

During the three months ended June 30, 2024, there have been no changes that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. Our process for evaluating controls and procedures is continuous and encompasses constant improvement of the design and effectiveness of established controls and procedures.

WARRANT TO PURCHASE COMMON STOCK

Alphatec Holdings, Inc.


Warrant Shares: 1,327,434		December 28, 2017

THIS WARRANT CERTIFIES THAT, for value received, Patrick S. Miles (the “Holder”), or its assigns, is entitled to purchase up to 1,327,434 shares of Common Stock (the “Shares”) of Alphatec Holdings, Inc., a Delaware corporation (the “Company”) at an exercise price equal to $5.00 per Share (the “Exercise Price”), all on the terms and subject to the conditions and limitation as set forth herein.

EXERCISE

Holder may exercise this Warrant in whole or in part, at any time and from time to time following June 28, 2018, in each case, by delivering a duly executed Notice of Exercise in substantially the form attached hereto as Appendix 1 to the principal office of the Company and a check for the aggregate Exercise Price for the Shares being purchased. Promptly after Holder exercises this Warrant, the Company shall deliver to Holder certificates for the Shares acquired, and, if this Warrant has not been fully exercised, a new Warrant representing the Shares not so acquired shall be delivered to Holder. Subject to Article 4 and Section 5.2 below, the Company agrees that any Shares acquired by exercise of this Warrant in accordance with this Article 1 shall be deemed to be issued to the Holder as the record holder of such Shares as of the close of business on the date on which the Notice of Exercise shall have been delivered and payment made for the Exercise Price as aforesaid.

Net Issue via Cashless Exercise. In lieu of exercising this Warrant by delivering a check for the aggregate Exercise Price for the Shares being purchased, this Warrant may also be exercised, in whole or in part, by means of a “cashless exercise” in which the Holder shall be entitled to receive a number of Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:

(A) = as applicable: (i) the VWAP on the Trading Day immediately preceding the date of the applicable Notice of Exercise if such Notice of Exercise is (1) both executed and delivered pursuant to Article 1 hereof on a day that is not a Trading Day or (2) both executed and delivered pursuant to Article 1 hereof on a Trading Day prior to the opening of “regular trading hours” (as defined in Rule 600(b)(64) of Regulation NMS promulgated under the federal securities laws) on such Trading Day, (ii) at the option of the Holder, (y) the VWAP on the Trading Day immediately preceding the date the applicable Notice of Exercise is delivered or (z) the Bid Price of the Common Stock on the principal Trading Market as reported by Bloomberg L.P. as of the time of the Holder’s execution of the applicable Notice of Exercise if such Notice of Exercise is executed during “regular trading hours” on a Trading Day and is delivered within two (2) hours thereafter pursuant to Article 1 hereof or (iii) the VWAP on the date of the applicable Notice of Exercise if the date of such Notice of Exercise is a Trading Day and such Notice of Exercise is both executed and delivered pursuant to Article 1 hereof after the close of “regular trading hours” on such Trading Day;

(B) = the Exercise Price of this Warrant, as adjusted hereunder; and

(X) = the number of Shares that would be issuable upon exercise of this Warrant in accordance with the terms of this Warrant if such exercise were by means of a cash exercise rather than a cashless exercise.

If Shares are issued in such a cashless exercise, the parties acknowledge and agree that in accordance with Section 3(a)(9) of the Securities Act, the Shares shall take on the characteristics of the Warrants being exercised, and the holding period of the Shares being issued may be tacked on to the holding period of this Warrant. The Company agrees not to take any position contrary to this provision.

“Bid Price” means, for any date, the price determined by the first of the following clauses that applies: (a) if the Common Stock is then listed or quoted on a Trading Market, the bid price of the Common Stock for the time in question (or the nearest preceding date) on the Trading Market on which the Common Stock is then listed or quoted as reported by Bloomberg L.P. (based on a Trading Day from 9:30 a.m. (New York City time) to 4:02 p.m. (New York City time)), (b) if OTCQB or OTCQX is not a Trading Market, the volume weighted average price of the Common Stock for such date (or the nearest preceding date) on OTCQB or OTCQX as applicable, (c) if the Common Stock is not then listed or quoted for trading on OTCQB or OTCQX and if prices for the Common Stock are then reported in the “Pink Sheets” published by OTC Markets Group, Inc. (or a similar organization or agency succeeding to its functions of reporting prices), the most recent bid price per share of the Common Stock so reported, or (d) in all other cases, the fair market value of a share of Common Stock as determined by an independent appraiser selected in good faith by the Purchasers of a majority in interest of the Securities then outstanding and reasonably acceptable to the Company, the fees and expenses of which shall be paid by the Company.

“VWAP” means, for any date, the price determined by the first of the following clauses that applies: (a) if the Common Stock is then listed or quoted on a Trading Market, the daily volume weighted average price of the Common Stock for such date (or the nearest preceding date) on the Trading Market on which the Common Stock is then listed or quoted as reported by Bloomberg L.P. (based on a Trading Day from 9:30 a.m. (New York City time) to 4:02 p.m. (New York City time)), (b) if OTCQB or OTCQX is not a Trading Market, the volume weighted average price of the Common Stock for such date (or the nearest preceding date) on OTCQB or OTCQX as applicable, (c) if the Common Stock is not then listed or quoted for trading on OTCQB or OTCQX and if prices for the Common Stock are then reported in the “Pink Sheets” published by OTC Markets Group, Inc. (or a similar organization or agency succeeding to its functions of reporting prices), the most recent bid price per share of the Common Stock so reported, or (d) in all other cases, the fair market value of a share of Common Stock as determined by an independent appraiser selected in good faith by the Purchasers of a majority in interest of the Securities then outstanding and reasonably acceptable to the Company, the fees and expenses of which shall be paid by the Company.

The Holder may elect net issue via cashless exercise by delivering a duly executed Notice of Exercise in substantially the form attached hereto as Appendix 1 to the principal office of the Company which affirmatively sets forth Holder’s election to elect net issue via cashless exercise. Notwithstanding anything herein to the contrary, on the termination date, as set forth in Article 3, this Warrant shall be automatically exercised via cashless exercise pursuant to this Article 1.

II.

ADJUSTMENTS TO THE SHARES

Split, Subdivision or Combination of Shares. Upon any subdivision of the Shares, by split or otherwise, or combination of the Shares, the number of Shares issuable upon the exercise of this Warrant shall forthwith be proportionately increased, in the case of a subdivision, or proportionately decreased in the case of a combination, and the Exercise Price shall forthwith be proportionately decreased in the case of a subdivision, or proportionately increased in the case of a combination.

Reclassification, Merger, Exchange or Substitution. Upon any reclassification, merger, exchange, substitution, or other event that results in a change of the number and/or class of the securities issuable upon exercise of this Warrant, the Holder shall be entitled to receive, upon exercise of this Warrant, the number and kind of securities and property that Holder would have received for the Shares if this Warrant had been exercised immediately before such reclassification, merger, exchange, substitution, or other event. The Company or its successor shall promptly issue to Holder a new Warrant for such new securities or other property. The new Warrant shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article

2 including, without limitation, adjustments to the Exercise Price and to the number of securities or property issuable upon exercise or conversion of the new Warrant. The provisions of this Section 2.2 shall similarly apply to successive reclassifications, mergers, exchanges, substitutions, or other events.

Notice of Adjustments. Whenever the number of Shares or Exercise Price is adjusted or there is any other adjustment of this Warrant as herein provided, the Company shall provide notice to the Holder of such adjustment or adjustments setting forth in reasonable detail the adjustments so made, a brief statement of the facts requiring such adjustment, and the computation by which such adjustment was made.

No Impairment. The Company shall not, through a reorganization, transfer of assets, consolidation, merger, dissolution, issue, or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed under this Warrant by the Company, but shall at all times in good faith assist in carrying out of all the provisions of this Article 2. The Company shall at all times reserve and keep available out of the aggregate of its authorized but unissued Shares, free of preemptive rights, such number of its duly authorized Shares, or other stock or securities deliverable pursuant to this Article 2, as shall be sufficient to enable the Company at any time to fulfill all of its obligations under this Warrant. The Company covenants that all Shares that may be delivered upon exercise of this Warrant, assuming full payment of the Exercise Price, shall upon delivery by the Company be duly authorized and validly issued, fully paid and nonassessable, free from all stamp taxes, liens and charges with respect to the issue or delivery thereof and otherwise free of all other security interests, encumbrances and claims of any nature whatsoever other than those created by Holder.

III.

DURATION

This Warrant shall expire and no longer be exercisable, and its provisions shall have no further force or effect upon the earlier of (a) the date which this Warrant has been exercised for the maximum amount of Shares available for issuance upon an exercise of this Warrant and (b) December 31, 2026.

IV.

Subject to such restrictions, the Company shall transfer all or portion of this Warrant from time to time upon the books to be maintained by the Company for that purpose, upon surrender hereof for transfer, properly endorsed or accompanied by appropriate instructions for transfer and such other documents as may be reasonably required by the Company, including, if required by the Company, an opinion of its counsel reasonably satisfactory to the Company to the effect that such transfer is exempt from the registration requirements of the Act, to establish that such transfer is being made in accordance with the terms hereof, and a new Warrant shall be issued to the transferee for the portion of this Warrant so transferred (and, if applicable, a new Warrant shall be issued to the Holder for any portion not transferred) and the surrendered Warrant shall be canceled by the Company.

The Holder acknowledges that the Shares acquired upon the exercise of this Warrant will have restrictions upon resale imposed by state and federal securities laws.

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.S. (“EOS”), is a medical technology company focused on the design, development, and advancement of technology for the better surgical treatment of spinal disorders. The Company, headquartered in Carlsbad, California, markets its products in the United States 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, 2023, which are included in the Company’s Annual Report on Form 10-K that was filed with the SEC. Operating results for the six months ended June 30, 2024 are not necessarily indicative of the results that may be expected for the year ending December 31, 2024, or any other future periods. 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, inventories, 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, and biologics are valued by utilizing a standard cost method that includes capitalized variances which together 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. 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 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 asset when one or more performance obligations have been completed by the Company and revenue has been recognized, but the customer's payment is contingent on the satisfaction of additional performance obligations. Contract assets are generally short-term in nature. 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. These amounts primarily relate to undelivered equipment and related services, or maintenance agreements. 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.

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.S. (“EOS”), is a medical technology company focused on the design, development, and advancement of technology for the better surgical treatment of spinal disorders. The Company, headquartered in Carlsbad, California, markets its products in the United States 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, 2023, which are included in the Company’s Annual Report on Form 10-K that was filed with the SEC. Operating results for the six months ended June 30, 2024 are not necessarily indicative of the results that may be expected for the year ending December 31, 2024, or any other future periods.
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, inventories, 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, and biologics are valued by utilizing a standard cost method that includes capitalized variances which together 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. 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 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 asset when one or more performance obligations have been completed by the Company and revenue has been recognized, but the customer's payment is contingent on the satisfaction of additional performance obligations. Contract assets are generally short-term in nature. 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. These amounts primarily relate to undelivered equipment and related services, or maintenance agreements. 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 Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In December 2023, the FASB issued Accounting Standard Update ("ASU") No. 2023-09, Income Taxes (Topic 740): Improvement to Income Tax Disclosures to enhance the transparency of income tax disclosures. The guidance in ASU No. 2023-09 allows for a prospective method of transition, with the option to apply the standard retrospectively. The standard is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The Company does not intend to early adopt the standard and is in the process of assessing the impact on its consolidated financial statements and related disclosures. In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures that expands disclosure requirements for reportable segments, primarily through enhanced disclosure of significant segment expenses. The guidance in ASU No. 2023-07 allows for a retrospective method of transition. The standard is effective for fiscal years beginning after December 15, 2023, and interim periods in fiscal years beginning after December 15, 2024, with early adoption permitted. The Company does not intend to early adopt the standard and is in the process of assessing the impact on its consolidated financial statements and related disclosures.
