NOTES TO CONDENSED CONSOLIDATED F INANCIAL 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 in 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 presentation 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, 2024, which are included in the Company’s Annual Report on Form 10-K that was filed with the SEC. Operating results for the nine months ended September 30, 2025 are not necessarily indicative of the results that may be expected for the full year or any other future periods.

Reclassification

Certain financial statement line items in the condensed consolidated financial statements for the period ended September 30, 2024, have been aggregated to conform to the current year’s presentation.

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

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. 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. 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 contract 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. In certain cases, the Company does offer the ability for customers to lease its imaging equipment, 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 directly 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 estimates the selling price of promised services included in the equipment sales price using an expected cost plus a margin approach and/or the separately observable price of such service, if available. The transaction price for a contract’s various performance obligations 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. The standard is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The Company is in the process of assessing the impact of this standard on its consolidated financial statements and related disclosures.

In November 2024, the FASB issued ASU No. 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Topic 220-40). Additionally, in January 2025, the FASB issued ASU 2025-01 to clarify the effective date of ASU 2024-03. The standard provides guidance to expand disclosures related to the disaggregation of income statement expenses. The standard requires, in the notes to the financial statements, disclosure of specified information about certain costs and expenses, which includes purchases of inventory, employee compensation, depreciation and intangible asset amortization included in each relevant expense caption. This guidance is effective for fiscal years beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027, on a retrospective or prospective basis, with early adoption permitted. The Company is in the process of assessing the impact of this standard on its consolidated financial statements and related disclosures.

In September 2025, the FASB issued ASU No. 2025-06, Targeted Improvements to the Accounting for Internal-Use Software (Subtopic 350-40). ASU 2025-06 removes references to prescriptive and sequential development stages, requiring companies to capitalize internal-use software costs when management commits to funding the software project and it is probable the project will be completed. This ASU 2025-06 is effective for all entities for fiscal years beginning after December 15, 2027, and for interim periods within those annual reporting periods. Early adoption is permitted. The Company is in the process of assessing the impact of this standard on its consolidated financial statements and related disclosures.

0.75% Convertible Senior Notes due 2030

In March 2025, the Company issued $405.0 million aggregate principal amount of senior unsecured 2030 Notes with a stated interest rate of 0.75% and a maturity date of March 15, 2030. The 2030 Notes began accruing interest immediately and are payable semi-annually in arrears on March 15 and September 15 of each year. The net proceeds from the sale of the 2030 Notes were approximately $392.9 million after deducting the initial purchasers’ offering expenses and before cash use for the 2030 Capped Call Transactions, as described below, and the repayment of 80% of the 2026 Notes, as described below. The 2030 Notes do not contain any financial covenants.

The 2030 Notes are convertible into shares of the Company’s common stock based upon an initial conversion rate of 64.3407 shares of the Company’s common stock per $1,000 principal amount of 2030 Notes (equivalent to an initial conversion price of approximately $15.54 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 2030 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 2030 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 September 17, 2029, holders may convert all or a portion of their 2030 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 2030 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 September 17, 2029, holders of the 2030 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 September 30, 2025, none of the conditions permitting the holders of the 2030 Notes to convert have been met. The 2030 Notes are classified as long-term debt on the condensed consolidated balance sheets as of September 30, 2025.

The 2030 Notes are redeemable, in whole or in part, at the Company’s option at any time, and from time to time, on or after March 20, 2028 and on or before the 60th scheduled trading day immediately before the maturity date, at a cash redemption price equal to the principal amount of the 2030 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 2030 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.

Table of Contents

If a fundamental change occurs prior to the maturity date, holders may require the Company to repurchase all or a portion of their 2030 Notes for cash at a price equal to 100% of the principal amount of the 2030 Notes plus accrued and unpaid interest. No principal payments are otherwise due on the 2030 Notes prior to maturity.

At the time of issuance, the Company determined that the 2030 Notes had an embedded conversion option that met the criteria to be bifurcated and accounted for separately from the 2030 Notes. The Company initially recorded the fair value of the embedded conversion option as a derivative liability and the principal amount of the 2030 Notes as a long-term liability, net of debt discount and deferred issuance costs. In June 2025, conditions necessary for separate accounting of the conversion option as a derivative liability were no longer met. Accordingly, the conversion option derivative liability was remeasured as of the date of the change and subsequently reclassified to additional paid-in capital on the Company’s condensed consolidated statements of shareholders’ equity (deficit). The annual effective interest rate for the 2030 Notes is 9.1%. The Company recognized interest expense on the 2030 Notes of $6.5 million and $14.4 million during the three and nine months ended September 30, 2025, respectively, which includes $5.7 million and $12.7 million for the amortization of debt discount costs, respectively. The Company uses the if-converted method for assumed conversion of the 2030 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 2030 Notes consists of the following (in thousands):

|  | September 30, 2025 |  |
Principal |  | $ | 405,000 |  |
Unamortized debt discount and debt issuance costs |  |  | (124,251 | ) |
Net carrying value |  | $ | 280,749 |  |

2030 Capped Call Transactions

In connection with the offering of the 2030 Notes, the Company entered into privately negotiated capped call transactions (the “2030 Capped Call Transactions”) with certain financial institutions. The 2030 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 2030 Notes upon conversion of the 2030 Notes in the event that the market price per share of the Company’s common stock is greater than the strike price of the 2030 Capped Call Transactions with such reduction and/or offset subject to a cap. The 2030 Capped Call Transactions have an initial cap price of $23.46 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 March 4, 2025, and is subject to certain adjustments under the terms of the 2030 Capped Call Transactions. Collectively, the 2030 Capped Call Transactions cover, initially, the number of shares of the Company’s common stock underlying the 2030 Notes, subject to anti-dilution adjustments substantially similar to those applicable to the 2030 Notes. The cost of the 2030 Capped Call Transactions was approximately $42.5 million.

The 2030 Capped Call Transactions are separate transactions and are not part of the terms of the 2030 Notes and will not affect any holder’s rights under the 2030 Notes. Holders of the 2030 Notes will not have any rights with respect to the 2030 Capped Call Transactions.

The 2030 Capped Call Transactions meet all of the applicable criteria for equity classification, and as a result, the related $42.5 million cost was recorded as a reduction to additional paid-in capital on the Company’s condensed consolidated statements of shareholders’ equity (deficit).

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”). On October 29, 2024, the Company entered into an amendment of the Braidwell Term Loan, which provides for an additional term loan of $50.0 million, subject to the terms of the original term loan credit facility. The Braidwell Term Loan matures on January 6, 2028. As of September 30, 2025, the outstanding balance under the Braidwell Term Loan wa s $200.0 million.

In conjunction with the issuance of the Braidwell Term Loan, the Company incurred $3.6 million in debt issuance costs and $3.5 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 September 30, 2025, debt issuance costs and debt discount, net of accumulated amortization, associated with the Braidwell Term Loan were both $2.2 million.

Table of Contents

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 September 30, 2025 was 10.00%. 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 a nd undrawn commitment fees incurred are due quarterly. The Company is also required to pay fees on any prepayment of the Braidwell Term Loan, ranging from 3.0% to 1.0% depending on the date of prepayment, and a final payment fee equal to 3.25% of the principal amount of the loans drawn. The effective interest rate as of September 30, 2025 was 11.7%. During the three months ended September 30, 2025, the Company recognized interest expense on the Br aidwell Term Loan of $5.7 million, which includes $0.2 million for both the amortization of debt issuance costs and debt discount. During the nine months ended September 30, 2025, the Company recognized interest expense on the Braidwell Term Loan of $16.2 million, which includes $0.3 million for the amortization of debt issuance costs and $0.4 million for the debt discount. D uring the three months ended September 30, 2024, the Company recognized interest expense on the Braidwell Term Loan of $4.4 million, which includes $0.2 million for the amortization of debt issuance costs and $0.1 million for the debt discount. During the nine months ended September 30, 2024, the Company recognized interest ex pense on the Braidwell Term Loan of $12.9 million, which includes $0.5 million for the amortization of debt issuance costs and $0.2 million for the debt discount. Upon the Braidwell Term Loan’s maturity, any outstanding principal balance, unpaid accrued interest, and all other obligations under the Braidwell Term Loan will be due and payable.

The 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 September 30, 2025.

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 originally provided up to $50.0 million in borrowing capacity to the Company with an accordion feature up to $75.0 million in borrowing capacity, based on a defined borrowing base. The borrowing base is calculated based on certain accounts receivable and inventory assets. The Company subsequently exercised the accordion feature and increased the borrowing capacity by $25.0 million up to the full $75.0 million borrowing capacity. The Revolving Credit Facility matures on Sep tember 29, 2027. As of September 30, 2025, the outstanding balance under the Revolving Credit Facility was $15.0 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 September 30, 2025, debt issuance costs, net of accumulated amortization, associated with the Revolving Credit Facility were $0.6 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 September 30, 2025 was 7.90%. Th e 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 $0.4 million and $1.3 million during the three and nine months ended September 30, 2025, respectively, which includes approximately $0.1 million and $0.2 million for the amortization of debt issuance costs during the three and nine months ended September 30, 2025, respectively. The Company recognized interest expense on the Revolving Credit Facility of $0.9 million and $2 million during the three and nine months ended September 30, 2024, respectively, which includes approx imately $0.1 million and $0.2 million for the amortization of debt issuance costs. Upon the Revolving Credit Facility’s maturity, any outstanding principal balance, unpaid accrued interest, and all other obligations under the Revolving Credit Facility will be due and payable.

The Revolving Credit Facility contains a lockbox arrangement clause requiring the Company to maintain a lockbox bank account. If the revolving loan availability is less than 30% of the revolving loan limit for five consecutive business days, or the Company is in default, MidCap will apply funds collected from the Company's lockbox account to reduce the outstanding balance of the Revolving Credit Facility. As of September 30, 2025, 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 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 September 30, 2025.

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.

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 September 30, 2025, none of the conditions permitting the holders of the 2026 Notes to convert have been met. The 2026 Notes are classified as current debt on the condensed consolidated balances sheet as of September 30, 2025.

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. In March 2025 the Company repurchased 80% of the 2026 Notes for $268.4 million. The Company determined that the redemption of the 2026 Notes should be accounted for as a partial extinguishment of the 2026 Notes. As a result of the partial extinguishment, the Company wrote off $2.3 million of the unamortized debt issuance costs and debt discou nt. The Company recorded a loss on debt extinguishment of $17.6 million during the nine months ended September 30, 2025.

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 $0.2 million and $1.3 million during the three and nine months ended September 30, 2025, respectively, which includes $0.1 million and $0.7 million for the amortization of debt issuance costs, respectively. The Company recognized interest expense on the 2026 Notes of $1.1 million and $3.3 million, during the three and nine months ended September 30, 2024, respectively, which includes $0.5 million and $1.5 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.

2026 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 rep aid in 2027. The outstanding obligation under each PGE loan as of September 30, 2025 wa s $1.6 million and $0.7 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 1.0%, resp ectively.

8. Commitments and Contingencies

Leases

The Company determines if an arrangement is a lease at inception by assessing whether there is an identified asset and whether the contract conveys the right to control the use of the identified asset in exchange for consideration over a period of time. If both criteria are met, the Company records the associated lease liability and corresponding right-of-use asset (“ROU asset”) upon commencement of the lease using a discount rate based on the incremental borrowing rate of interest that the Company would borrow on a collateralized basis for an amount equal to the lease payments in a similar economic environment. Any short-term leases defined as twelve months or less or month-to-month leases are excluded and are expensed each month. Total costs associated with these short-term leases are immaterial to all periods presented.

The Company leases office and storage facilities and equipment under various operating and financing lease agreements. The initial terms of these leases range from 1 to 10 years and generally provide for periodic rent increases. The Company’s lease agreements do not contain any material variable lease payments, residual value guarantees or material restrictive covenants. The Company aggregates all lease and non-lease components for each class of underlying assets into a single lease component and variable charges for common area maintenance and other variable costs are recognized as expense as incurred. Total variable costs associated with leases for the three and nine months ended September 30, 2025 were immaterial.

Purchase Commitments

The Company is obligated to meet certain minimum purchase commitment requirements with a third-party supplier through December 2026. As of September 30, 2025, the remaining minimum purchase commitment required by the Company under the agreement is $6.2 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

Table of Contents

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.

In May 2025, the Company entered into a settlement with a shareholder to resolve a legal dispute. The Company recorded the amount of the settlement, which is included in litigation-related expenses in the condensed consolidated statements of operations and accrued expenses and other current liabilities on the condensed consolidated balance sheets for the nine months ended September 30, 2025.

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, Inc. 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 September 30, 2025, 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.

Salary-to-Equity Conversion Program

On March 31, 2025, the Compensation Committee of the Board of Directors of the Company adopted a salary conversion plan (the “Plan”) under which the cash payment of base salaries for certain Company executive officers was reduced by 10% to 50% and, in exchange, the Company's executive officers were granted RSUs. The RSUs granted under the Plan will vest in two equal installments on August 5, 2025 and December 5, 2025, subject to the respective executive officer's continued employment with the Company on each vesting date.

10. 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 CODM is the Chief Executive Officer. 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. Significant segment expenses regularly provided to the CODM are consolidated research and development expenses and consolidated sales, general and administrative expenses. Refer to the consolidated statements of operations for consolidated research and development expenses and consolidated sales, general and administrative expenses. The Company determined that consolidated net loss is the Company’s measure of segment profit or loss.

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

11. Net Loss Per Share

Basic net loss per share is calculated by dividing the net loss available to common stockholders by the weighted-average number of common shares outstanding for the period. If applicable, diluted net loss per share attributable to common stockholders is calculated by dividing net loss available to common stockholders by the diluted weighted-average number of common shares outstanding for the period, determined using the treasury-stock method and the if-converted method for convertible debt. For purposes of this calculation, common stock subject to repurchase by the Company, common stock issuable upon conversion or exercise of convertible notes, preferred shares, options, and warrants are considered to be common stock equivalents and are only included in the calculation of diluted earnings per share when their effect is dilutive. Due to the Company’s net loss position, the effect of including common stock equivalents in the earnings per share calculation is anti-dilutive, and therefore not included.

The following table presents the computation of basic and diluted net loss per share (in thousands, except per share amounts):

|  | Three Months Ended September 30, |  |  | Nine Months Ended September 30, |

12. Income Taxes

To calculate its interim tax provision, at the end of each interim period the Company estimates the annual effective tax rate, adjusted for discrete items arising in that quarter. The computation of the annual estimated effective tax rate at each interim period requires certain estimates and significant judgment including, but not limited to, the estimated annual taxable income or loss for the year and projections of the proportion of income earned and taxed in foreign jurisdictions. The accounting estimates used to compute the provision for income taxes may change as new events occur, additional information is obtained, or the tax environment changes.

The Company’s effective tax rate from operations w as (0.26%) and 0.02% for the three and nine months ended September 30, 2025, respectively. The Company's effective tax rate from operations was 0.09% and 0.30% for the three and nine months ended September 30, 2024, 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.

13. 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 nine months ended September 30, 2025, the Company purchased inventory in the amounts of $3.1 million and $8.2 million, respectively, from the Squadron Supplier Affiliate. For the three and nine months ended September 30, 2024, the Company purchased inventory in the amounts of $5.7 million and $18.3 million, respectively, from the Squadron Supplier Affiliate. As of September 30, 2025, and December 31, 2024, the Company had $2.9 million and $1.8 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, 2024, 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 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.

Recent Developments

0.75% Senior Convertible Notes due 2030

In March 2025, we issued $405.0 million principal amount of unsecured senior convertible notes with a stated interest rate of 0.75% (the "2030 Notes"). The 2030 Notes began accruing interest immediately and interest is payable semi-annually in arrears on March 15 and September 15 of each year, beginning on September 15, 2025. The 2030 Notes are convertible into shares of our common stock based upon an initial conversion rate of 64.3407 shares of our common stock per $1,000 principal amount of 2030 Notes (equivalent to an initial conversion price of approximately $15.54 per share). The net proceeds from the sale of the 2030 Notes were approximately $392.9 million after deducting the offering expenses. The 2030 Notes will mature on March 15, 2030, unless earlier converted, redeemed, or repurchased. We used $42.5 million of the net proceeds from the 2030 Notes offering to enter into separate capped call instruments with certain financial institutions. The capped call transactions effectively limit the premium for conversion of the 2030 Notes to 100% and are generally expected to reduce potential dilution to our common stock upon any conversion of the 2030 Notes and/or offset any payments we make upon conversion. In addition, we repurchased 80% of our 2026 convertible notes (the "2026 Notes") for approximately $268.4 million. We intend to use the remainder of the net proceeds from the 2030 Notes for general corporate purposes.

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.

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.

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.

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

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, loss on debt extinguishment, gain on derivative liability, and other non-operating gains and losses.

Income tax provision (benefit). Income tax provision (benefit) 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 September 30, 2025, 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, 2024, filed with the SEC.

The decrease during the three months and nine months ended September 30, 2025 was primarily due to a decrease in stock-based compensation.

Sales, general and administrative expenses. Sales, general and administrative expenses increased $15.1 million, or 14%, and $34.3 million, or 10%, during the three and nine months ended September 30, 2025, respectively, compared to the same period in 2024. 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.

Litigation-related expenses. Litigation-related expenses increased $4.4 million, or 212%, and $11.7 million, or 136%, for the three and nine months ended September 30, 2025, respectively, compared to the same period in 2024. The increase for the three month period ended September 30, 2025 was primarily related to ongoing litigation. The increase for the nine month period ended September 30, 2025 was primarily related to a litigation settlement during the three months ended March 31, 2025, and ongoing litigation matters.

Amortization of acquired intangible assets. Amortization of acquired intangible assets remained consistent for the three and nine months ended September 30, 2025, respectively, compared to the same period in 2024.

Restructuring expenses. Restructuring expenses decreased $0.9 million, or 100%, and $1.5 million, or 80%, during the three and nine months ended September 30, 2025, respectively, compared to the same period in 2024. The decrease in restructuring expenses is primarily due to costs associated with the relocation of office facilities in Paris, France and personnel related expenses in the prior period that did not recur.

Interest expense, net, increased $6.3 million, or 96%, and $15.3 million, or 86%, during the three and nine months ended September 30, 2025, respectively, compared to the same period in 2024. The increase in interest expense, net, was primarily due to drawing an additional $50.0 million on the Braidwell Term Loan in October 2024, and the amortization of debt discount associated with the 2030 Notes. Net cash interest was $5.3 million and $16.0 million for the three and nine months ended September 30, 2025, respectively. Net non-cash interest was $7.6 million and $17.1 million for the three and nine months ended September 30, 2025, respectively.

Loss on debt extinguishment increased $17.6 million, or 100%, during the nine months ended September 30, 2025, compared to the same period in 2024. The increase in loss on debt extinguishment relates to the redemption of 80% of the 2026 Notes.

Gain on derivative liability increased $0.6 million, or 100%, during the nine months ended September 30, 2025, compared to the same period in 2024. The increase in gain on derivative liability relates to the change in the valuation of the derivative liability associated with 2030 Notes from inception to June 12, 2025, the date the conditions necessary for separate accounting of the conversion option as a derivative liability were no longer met.

Other income, net, decreased $0.3 million, or 51%, and increased $0.7 million, or 82%, during the three and nine months ended September 30, 2025, respectively, compared to the same period in 2024. The increase in other income, net, during the nine months ended September 30, 2025, was primarily due to receiving the employee retention credit and fluctuations in foreign currency rates.

The change in the income tax provision (benefit) for the three and nine months ended September 30, 2025, compared to the same period in 2024, was primarily related to the recognition of income taxes 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.

We do not have any material financial exposure to one customer or one country, outside of the United States, 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 8, 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 $155.7 million and $138.8 million at September 30, 2025, and December 31, 2024, 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.

Item 3. Quantitative and Qualitati ve Disclosures About Market Risk

We have evaluated the information required under this item that was disclosed under Item 7A in our Annual Report on Form 10-K for the year ended December 31, 2024, and there have been no significant changes to this information.

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 September 30, 2025. Based on such evaluation, our management has concluded that as of September 30, 2025, our disclosure controls and procedures are effective.

Changes in Internal Control over Financial Reporting

During the three months ended September 30, 2025, 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.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

For a description of our material legal proceedings, refer to Note 8 of our Notes to Condensed Consolidated Financial Statements included in this Quarterly Report on Form 10-Q, which is incorporated herein by reference.

Item 1A. Ri sk Factors

There have been no material changes to the risk factors described under Item 1A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2024, filed with the SEC on February 26, 2025, except as follows:

Tariffs and other trade measures could adversely affect our business, results of operations, financial position and cash flows

Our business and results of operations may be adversely affected by uncertainty and changes in U.S. trade policies, including tariffs, trade agreements or other trade restrictions imposed by the U.S. or other governments. While most of our suppliers are based in the U.S., some of the materials we use to manufacture our products are directly affected by tariffs imposed on products imported into the U.S. Additionally, we are increasing our international sales, which may be subject to retaliatory measures by other countries. The imposition of tariffs and other trade restrictions, as well as the escalation of trade disputes and any downturns in the global economy resulting therefrom, could adversely affect our business, financial condition and results of operations.

Item 2. Unregiste red Sales of Equity Securities and Use of Proceeds

During the three months ended September 30, 2025, we issued unregistered shares of common stock as described in the following table:

Date Issued | Number of Shares | Grant Date Fair Value per Share (2) |
July 1, 2025 | 2,090(1) | $ | 10.93 |

(1) Pursuant to consulting services rendered to the Company.

(2) Based on the market price of common stock on the issuance date.

The issuances of the foregoing securities were made in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities Act of 1933, as amended, as there was no general solicitation and the transactions did not involve a public offering.

Item 5. Other Information

Adoption, Modification or Termination of Trading Arrangements

A portion of the compensation of our directors and officers is in the form of equity awards, and, from time to time, directors and officers engage in open-market transactions with respect to the securities they acquire pursuant to such equity awards we have issued.

Transactions in our securities by directors and officers are required to be made in accordance with our insider trading policy, which requires that the transactions comply with applicable U.S. federal securities laws that prohibit trading while in possession of material nonpublic information. Rule 10b5-1 under the Exchange Act provides an affirmative defense that enables directors and officers to prearrange transactions in our securities in a manner that avoids concerns about initiating transactions while in possession of material nonpublic information.

During the quarter ended September 30, 2025, none of our directors or executive officers (as defined in Rule 16a-1(f) under the Exchange Act) adopted, modified or terminated any contract, instruction or written plan for the purchase or sale of our securities that was intended to satisfy the affirmative defense conditions of Rule 10b5-1(c)
