Exhibit 99.3

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

On May 13, 2021, Alphatec Holdings, Inc. (“ATEC” or the “Company”) completed its initial tender offer (as set forth in Rule 14d-1(d) under the Securities Exchange Act of 1934) (“Tender Offer”) of EOS Imaging, SA (“EOS”) pursuant to the recommended cash offer of €2.45 (translated into $2.98 at the May 12, 2021 spot rate) per EOS Share (“EOS Share”) and €7.01 (translated into $8.52 at the May 12, 2021 spot rate ) per OCEANE outstanding convertible bond (“OCEANEs”) (such offer, the “Cash Offer Document,” published December 16, 2020 by ATEC such Tender Offer and its acceptance, “the Acquisition”).

The Acquisition of EOS was accounted for using the acquisition method of accounting as per the provisions of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 805, Business Combinations (“ASC 805”), with ATEC representing the accounting acquirer under this guidance. The unaudited pro forma condensed combined financial statements were prepared in accordance with Article 11 of Regulation S-X, as amended by SEC Final Rule Release No. 33-10786, Amendments to Financial Disclosures About Acquired and Disposed Businesses. The unaudited pro forma condensed combined financial information is presented to illustrate the estimated effects of the Acquisition. For each of the periods presented, the pro forma financial information reflects the combination of historical financial information of ATEC and EOS, adjusted to give effect to the acquisition method of accounting in accordance with ASC 805, as subsequently described in greater detail. Furthermore, additional pro forma adjustments have also been reflected to address differences in reporting currencies, differences in bases of accounting, and differences in the classification and presentation of certain financial information. For purposes of certain disclosures that follow, ATEC and EOS may be referred to collectively as the “Combined Company.”

The unaudited pro forma condensed combined statements of operations for the year ended December 31, 2020 and the six months ended June 30, 2021 are presented herein. The unaudited pro forma condensed combined statements of operations combine the historical results of ATEC and EOS for the year ended December 31, 2020 and the six months ended June 30, 2021 and give effect to the Acquisition as if it occurred on January 1, 2020.

The pro forma adjustments included in this document are subject to modification based on the final determination of the fair value of the assets acquired and liabilities assumed, additional analysis, and additional information that may become available, which may cause the final adjustments to be materially different from the pro forma condensed combined financial statements presented below. Following the consummation of the Acquisition, ATEC management performed a detailed review of EOS’ accounting policies in an effort to determine if differences in accounting policies require further reclassification of EOS’ results of operations or reclassification of assets or liabilities to conform to ATEC’s accounting policies and classification. As a result, ATEC may subsequently identify additional material differences in the accounting policies which could have a material impact on the unaudited pro forma combined financial information.

The unaudited pro forma condensed combined financial information presented is for informational purposes only and is not necessarily indicative of results of operations that would have been realized if the Acquisition had been completed on the dates set forth above, nor is it indicative of future results or financial position of the Combined Company. Additionally, the final determination of the purchase price and the purchase price allocation, upon the completion of the Acquisition, will be based on EOS’ net assets acquired as of that date and will depend on a number of factors that cannot be predicted with certainty at this time. The unaudited pro forma condensed combined financial information does not reflect any anticipated synergies or dis-synergies, operating efficiencies or cost savings that may result from the Acquisition or potential divestitures that may occur subsequent to the completion of the Acquisition or any Acquisition and integration costs that may be incurred. The pro forma adjustments, which ATEC believes are reasonable under the circumstances, are preliminary and are based upon available information and certain assumptions described in the accompanying notes to the unaudited pro forma condensed combined financial information. Actual results and valuations may differ materially from the assumptions within the accompanying unaudited pro forma condensed combined financial information.

These unaudited pro forma condensed combined financial statements should be read in conjunction with the following:

• The historical audited consolidated financial statements of ATEC as of and for the year ended December 31, 2020 included in ATEC’s Annual Report on Form 10-K for the year ended December 31, 2020 filed with the SEC on March 5, 2021;

• The historical unaudited consolidated financial statements of ATEC as of and for the six months ended June 30, 2021 included in ATEC’s Quarterly Report on Form 10-Q for the quarter ended June 30, 2021 filed with the SEC on August 3, 2021; and

NOTES TO THE UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION

(In USD thousands, except per share data and as otherwise noted)

Note 1 – Description of Business Combination

On May 13, 2021, ATEC completed the purchase of 15,815,971 EOS Shares and 2,312,074 OCEANEs pursuant to the Tender Offer. Prior to May 13, 2021 ATEC acquired 7,940,090 EOS Shares and 174,061 OCEANEs on the open market outside of the Tender Offer which were recorded as investments in equity and debt securities, respectively. After the completion of the initial Tender Offer, the Company’s holdings of EOS represent approximately 89.1% of the outstanding EOS Shares and 57.2% of the OCEANEs, equal to approximately 80.0% of the capital and voting rights of EOS on a fully diluted basis. Pursuant to applicable French laws and regulations, the Tender Offer was reopened by the Autorité des Marchés Financiers (the “AMF”) in France to purchase all of the remaining EOS Shares and OCEANEs at the same respective prices as in the initial Offer on May 17, 2021. The results of the completion of the initial Tender Offer were published on May 10, 2021, by the AMF, and settlement occurred on May 13, 2021. In connection with the proposed Acquisition of EOS, the Company announced in December 2020 a definitive securities purchase agreement to raise $138.0 million in a private placement of common stock at a price of $11.11 per share. The private placement, which closed on March 1, 2021, generated net proceeds of $131.8 million, net of fees related to the private placement.

Note 2 – Basis of Presentation

The accompanying unaudited pro forma condensed combined statements of operations for the year ended December 31, 2020 and the six months ended June 30, 2021 are presented herein. The unaudited pro forma condensed combined statements of operations combine the historical results of ATEC and EOS for the year ended December 31, 2020 and the six months ended June 30, 2021 and give effect to the Acquisition as if it occurred on January 1, 2020. The historical financial information has been adjusted to give effect to pro forma adjustments that address differences in reporting currencies, differences in bases of accounting, and differences in the classification and presentation of certain financial informationand reflect transaction accounting adjustments, as well as other adjustments deemed to be directly related to the Acquisition, irrespective of whether such adjustment is deemed to be recurring or not. Any adjustments for differences in bases of accounting are determined after taking into effect the impacts of purchase accounting.

ATEC is deemed to be the accounting acquirer and the pro forma adjustments are preliminary and are based on estimates that are subject to change. The Combined Company will not be a “foreign private issuer” as defined in Rule 405 under the Securities Act and Rule 3b-4(c) under the Exchange Act. Accordingly, the pro forma information of the Combined Company is prepared in accordance with United States Generally Accepted Accounting Principles (“U.S. GAAP”).

ATEC’s historical audited financial statements were prepared in accordance with U.S. GAAP and presented in thousands of U.S. dollars (“USD”). EOS’ group audited consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as adopted by the International Accounting Standards Board (“IASB”) and presented in thousands of Euros (“EUR”). Certain reclassifications were made to align EOS’ financial statement presentation with that of ATEC based on information available to date (see Note 5) and to conform EOS’ financial statements to be prepared in accordance with U.S. GAAP (see Note 6). The unaudited pro forma condensed combined statements of operations also include certain purchase accounting adjustments (see Note 7). Following the consummation of the Acquisition, ATEC management will conduct a detailed review of the accounting for the Acquisition and as a result of that review, ATEC management may identify differences that, when finalized, could have a material impact on the unaudited pro forma condensed combined financial information.

Note 3 – Purchase Price

The total cash paid for the acquisition of EOS is approximately $66.5 million which along with the pre-existing equity and debt interest held in ATEC accounts for approximately 80% of the capital and voting rights of EOS. The acquisition consists of the purchase of both EOS Shares and OCEANEs.

EOS Shares

ATEC purchased approximately 89.1% of the total outstanding EOS Shares as of the date of the Acquisition for approximately $46.9 million (translated from Euros to USD at the May 13, 2021 spot rate) and is based on  EOS shareholders receiving a collective €38.8 million in cash pursuant to the Tender Offer price of €2.45 (translated into $2.97 at the May 13, 2021 spot rate) per share of EOS stock.

OCEANEs

ATEC additionally acquired 57.2% of outstanding OCEANE bonds for approximately $19.6 million (translated from Euros to USD at the May 13, 2021 spot rate) and is based on OCEANE holders receiving a collective €16.2 million in cash based on the Tender Offer price of  €7.01 (translated into $8.49 at the May 13, 2021 spot rate) per unit of OCEANE bonds.

The remaining 10.9% of outstanding EOS Shares was recognized as noncontrolling interest on the balance sheet in the amount of $8.5 million as of May 13, 2021. Additionally, net loss attributable to such noncontrolling interest of $1.3 million is recognized for the year ended December 31, 2020.

ATEC completed the purchase of EOS’ remaining outstanding and issued EOS Shares on June 2, 2021 for€7.0 million.

Note 4 - Preliminary Purchase Price Allocation

Under the acquisition method of accounting, EOS’ assets and liabilities will be recorded at fair value at the date of the completion of the Acquisition and combined with the historical carrying amounts of ATEC’s assets and liabilities. For this purpose, fair value shall be determined in accordance with the fair value concepts defined in ASC Topic 820, Fair Value Measurement (“ASC 820”). Fair value is defined in ASC 820 as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.” Fair value measurements can be highly subjective and can involve a high degree of estimation. ATEC’s cost to acquire EOS has been allocated to the assets acquired, liabilities assumed and goodwill based upon management’s preliminary estimate of what their respective fair values are as of the Acquisition date of May 13, 2021.  

The final determination of the purchase price allocation is anticipated to be completed as soon as practicable after completion of the Acquisition and will be based on the fair values of the assets acquired and liabilities assumed as of the Acquisition closing date. The final amounts allocated to assets acquired and liabilities assumed could differ significantly from the amounts presented in the unaudited pro forma condensed combined financial statements.

The purchase price is allocated to the underlying assets acquired and liabilities assumed based on the midpoint of their respective estimated fair values, with any excess purchase price allocated to goodwill as follows (in USD thousands):

Equity/Debt Interest Held		$	25,026
Cash consideration			66,528
Noncontrolling interest			8,454
Cash and Cash Equivalents	16,778
Accounts receivable, net	9,083
Inventory	26,531
Property, plant and equipment	1,650
Other assets acquired	9,158
Identifiable intangible assets acquired	71,500
Goodwill	31,822
Estimated fair value of total assets acquired	166,522
Contract liabilities	21,196
Long-term debt	15,297
Other liabilities assumed	30,021
Estimated fair value of total liabilities assumed	66,514
Estimated fair value of net acquired assets		$	100,008

Note 5 – Financial Statement Translation of and Adjustments to EOS’ Historical Financial Statements to Conform to ATEC’s Policies and Presentation

EOS’ consolidated statement of operations as of and for the year ended December 31, 2020 and the six months ended June 30, 2021 have been prepared in accordance with IFRS as adopted by the IASB, which differs in certain material respects from U.S. GAAP and ATEC’s accounting policies. This statement of operations for the year ended December 31, 2020 and the six months ended June 30, 2021 have been adjusted to align EOS’ historical statement of operations for the year ended December 31, 2020 and the six months ended June 30, 2021 to ATEC’s U.S. GAAP accounting policies after taking into effect the impacts of purchase accounting.

For purposes of preparing the unaudited pro forma condensed combined financial information the historical financial information of EOS was translated from EUR to USD using the following historical exchange rates:

Period of Exchange Rate	$ / €
Statement of Operations for the six months ended June 30, 2021 average exchange rate for that period		1.21
Statement of Operations for the year ended December 31, 2020 average exchange rate for that period		1.14

Translation, Reclassification, and Policy Alignment

Translation and Alignment of EOS Historical Financial Statements

EOS has historically prepared and reported its financial information in EUR. However, ATEC’s reporting currency is USD. Accordingly, EOS’ historical financial information was translated from EUR into USD, and aligned into certain ATEC financial statement line items prior to inclusion in the unaudited pro forma condensed combined statement of operations for the year ended December 31, 2020 and the six months ended June 30, 2021. Information regarding EOS’ historical financial information both prior to and subsequent to translation and grouping as well as the foreign currency exchange rates at which such information was translated into USD, is summarized below:

Reclassification Adjustments

A. In addition to the translation and alignment of EOS’ historical financial information to conform to ATEC’s financial statements reporting currency and financial statement line items, the following summary represents reclassifications to conform EOS’ historical financial information to financial statement line items and presentation of the Combined Company based on ATEC’s accounting policies:

EOS December 31, 2020 Statement of Operations Reclassification Adjustments

i. R&D tax credits of $1.2 million (€1.0 million) from Other income to Research and development.

ii. CVAE tax expenses of $82 thousand (€72 thousand) from Sales, general and administrative to Income tax provision, net.

iii. Payments received for government assistance of $1.3 million (€1.1 million) from Other income to Other income (expense), net.

iv. Represents adjustments to align the treatment of certain rental, indirect production, and direct production costs with treatment by ATEC of $216 thousand (€189 thousand) from Cost of revenues and $447 thousand (€392 thousand) from Sales, general and administrative to Research and development.

v. Includes a reclass of transaction related expenses of $1.4 million (€1.2 million) between Sales, general and administrative and Transaction related expenses.

EOS June 30, 2021 Statement of Operations Reclassification Adjustments

i. R&D tax credits of $451 thousand (€373 thousand) from Other income and to Research and development.

ii. Payments received for government assistance of $105 thousand (€87 thousand) from Other income to Other income (expense), net.

iii. Represents adjustments to align the treatment of certain rental, indirect production, and direct production costs with treatment by ATEC of $152 thousand (€126 thousand) from Cost of revenues and $215 thousand (€178 thousand) from Sales, general and administrative to Research and development.

Conforming Accounting Policies

The following adjustment has been made to align EOS’ historical statement of operations for the year ended December 31, 2020 and statement of operations for the six months ended June 30, 2021 to ATEC’s accounting policies:

B. Cost of revenue. Represents adjustments to (1) capitalize additional costs into inventory associated with internal production wages, amortization of equipment used in production, and rent of space used in production and (2) utilize standard costing approximating average costs determined on a first-in first-out basis rather than weighted average unit cost.
