Notes to Arxis, Inc. Condensed Consolidated Financial Statements

(Unaudited, in thousands, except where explicitly stated)

Note 1. Organization and Nature of Operations

Organization and Description of Business

Arxis, Inc. was incorporated as a Delaware corporation on October 3, 2025, for the purpose of effecting the reorganization transaction on April 16, 2026 as described below (the “Reorganization”). Prior to the Reorganization, Arxis, Inc. did not conduct any activities other than those incidental to its formation and the planning and execution of the Reorganization. See “Note 14. Equity” for further information on the Company’s outstanding capital stock following the Reorganization.

On April 16, 2026, the Company completed the Reorganization, pursuant to which wholly owned merger subsidiaries of Arxis, Inc. merged with and into Arcline Engineered Polymer Topco, L.P., Hawkeye TopCo, L.P., Connector TopCo, L.P., and Ovation TopCo, L.P. and certain of their respective wholly-owned subsidiaries (collectively, the “Arxis Businesses”), with the Arxis Businesses surviving and becoming wholly owned by Arxis, Inc. The Reorganization was accounted for as a transaction between entities under common control. Prior to April 16, 2026, the Arxis Businesses operated under common control.

Unless otherwise indicated or the context otherwise requires, references in these financial statements to “Arxis,” or the “Company,” refer to (i) Arxis, Inc. and its subsidiaries after the Reorganization on April 16, 2026, and (ii) the Arxis Businesses for periods prior to the Reorganization.

Arxis designs, manufactures, and sells highly engineered electronic and mechanical components primarily used in mission-critical applications. The Company serves diverse end markets including defense and space, commercial aerospace, and industrial technology, and operates highly specialized manufacturing facilities globally, with a focus on domestic manufacturing.

Initial Public Offering

In April 2026, the Company consummated its initial public offering (“IPO”), in which the Company issued and sold 46,575 shares of Class A common stock, $0.01 par value per share, at a public offering price of $28.00 per share. The Company received net proceeds from the IPO of$1,220,603 after deducting$61,945 of underwriting discounts and commissions and$21,552 of offering expenses. Prior to the IPO, the Company capitalized$14,402 of the offering expenses, which consisted of accounting, legal and other fees directly related to the IPO. In connection with the IPO, the deferred offering costs were reclassified to stockholders’ equity.

The Company used a portion of the net proceeds to prepay borrowings under the 2025 Term Loan, with the remainder to be used for working capital and other general corporate purposes. See “Note 11. Debt” for further information on the prepayment.

Note 2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the Company's audited combined financial statements and the related notes thereto included in the Company's prospectus filed with the SEC on April 16, 2026 pursuant to Rule 424(b) of the Securities Act of 1933, as amended, in connection with the Company's IPO (the "Prospectus"). See "Note 1. Organization and Nature of Operations" for further details regarding the IPO. The December 31, 2025 balance sheet was derived from the Company's audited combined financial statements.

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been omitted pursuant to the rules and regulations of the SEC. In the opinion of management, the unaudited condensed consolidated financial statements reflect all adjustments, consisting only of normal recurring adjustments, that are necessary for a fair presentation of the Company's condensed consolidated financial position, results of operations, and cash flows for the interim periods presented. Certain columns and rows may not add due to the use of rounded numbers. Quarterly results are not necessarily indicative of the results to be expected for the entire fiscal year.

Following the Reorganization, the financial statements are presented on a condensed consolidated basis and all intercompany accounts and transactions have been eliminated in consolidation. For the periods prior to the Reorganization, the financial statements are presented on a condensed combined basis andcombine:(i) the consolidated financial statements of Arcline Engineered Polymer Topco, L.P., (ii) the consolidated financial statements of Hawkeye TopCo, L.P., (iii) the consolidated financial statements of

Connector TopCo, L.P., and (iv) the financial statements of Ovation TopCo, L.P., which include only the operations and entities contributed to Arxis, Inc. and therefore do not represent the full consolidated results of Ovation TopCo, L.P. For each of the aforementioned consolidated financial statements, all significant intercompany accounts and transactions have been eliminated in consolidation.

Significant Accounting Policies

There have been no material changes to the Company’s significant accounting policies and the relevant recently issued accounting pronouncements not yet adopted from those described in the condensed consolidated financial statements and related notes included in our Quarterly Report for the period ended June 30, 2026 on Form 10-Q. Additional information regarding the calculation of net income (loss) per share is provided below.

Net Income (Loss) Per Share

Basic net income (loss) per common share is computed by dividing net income (loss) attributable to the common shareholders by the weighted-average basic common shares outstanding. The Company utilizes the two-class method required for participating securities to compute net income (loss) per common share. Under the two-class method, net income for each period is allocated between the Company's common stockholders and the holders of the participating securities based on their respective rights to participate in dividends and undistributed earnings, assuming all such earnings for the period had been distributed.

The Company considers its convertible common stock to be a participating security. Prior to satisfaction of the applicable conversion conditions, the holder of the convertible common stock is entitled to receive dividends, if any, on an as-converted basis. Because the convertible common stock will be forfeited if the holder ceases to provide services under the Advisory and Consulting Agreement before the fifth anniversary of the IPO (and is subject to the additional conditions described in “Note 14. Equity”), it is not considered outstanding for purposes of computing basic net income (loss) per share. As the convertible common stock consists of a single share that is not considered outstanding, basic and diluted net income (loss) per share for the convertible common stock is not meaningful and is not presented. See "Note 14. Equity" for further discussion of the terms of the convertible common stock.

Diluted net income per common share is computed by dividing net income attributable to common stockholders, adjusted for the reallocation of undistributed earnings, by the weighted-average diluted common shares outstanding, which includes the dilutive effect of potentially dilutive securities. Unvested restricted shares and restricted stock units do not have nonforfeitable rights to dividends, are not participating securities, and their dilutive effect is determined using the treasury stock method. The dilutive effect of the convertible common stock is determined using the if-converted method or the two-class method, whichever is more dilutive. Potentially dilutive securities are considered in sequence from the most dilutive to the least dilutive and are excluded when their effect would be antidilutive.

The rights, including the liquidation and dividend rights, of the holders of Class A common stock, Class B common stock, and Class C common stock are identical, except with respect to voting. For the periods presented, the Company did not have any outstanding shares of Class C common stock. See "Note 16. Net Income (Loss) Per Share" for further details.

Note 3. Business Combinations

Schatz

On September 2, 2026, the Company acquired a 100% equity interest in Schatz Bearing, LLC ("Schatz"), a designer and manufacturer of precision ball bearings and bearing assemblies for aerospace, defense, medical, and other high-reliability applications.

Costs associated with the issuance of common stock issued as consideration were immaterial.

The preliminary purchase price allocation to the underlying assets acquired and liabilities assumed based on their fair values as of the acquisition date consisted of total assets acquired of$913,968, including$462,000 of intangible assets,$354,577 of goodwill,$52,496 of inventories, and$44,896 of all other current and non-current assets, with$136,894 of assumed total liabilities, which includes$115,669 of deferred tax liabilities. Goodwill was primarily attributable to synergies and economies of scale expected from combining the operations of the Company and Omnetics. Goodwill is not deductible for tax purposes.

Omnetics' operations generated approximately$17,503 of revenue and$(302) of net loss before income taxes for the period from the Closing Date through September 30, 2026.

Pro Forma Financial Information (Unaudited)

The following unaudited pro forma financial information summarizes the results of operations of the Company for the periods indicated as if the acquisition had been completed on January 1, 2025. The unaudited pro forma information is not necessarily indicative of the results that the Company would have achieved had the Omnetics acquisition actually occurred on January 1, 2025, nor does such information purport to be indicative of future financial operating results.

The unaudited pro forma financial information includes, where applicable, adjustments for (i) the recognition in cost of revenue of the amortization of the inventory step-up (and the reversal of the related amortization recognized in the post-acquisition period), (ii) amortization expense related to acquired intangible assets, (iii) removal of the historical results of operations of a variable interest entity (the “VIE”) previously consolidated by Omnetics, as the agreements between Omnetics and the VIE were terminated on the Closing Date, and (iv) associated tax-related impacts of adjustments. These pro forma adjustments are based on the available information as of the date hereof and upon assumptions that the Company believes are reasonable to reflect the impact of the acquisition with the Company's historical financial information on a pro forma basis. Adjustments do not include costs related to integration activities, cost savings, or synergies that have been or may be achieved by the combined business.

Other Acquisitions

In the third quarter of 2026, the Company acquired 100% equity interests in two complementary businesses, one that specializes in custom position sensing and measurement technologies for mission-critical aerospace and defense platforms, and another that provides high-performance semiconductor packaging, assembly, and test services for defense, test and measurement, and industrial applications. The acquisitions complement the Company's existing product portfolio and expand its capabilities in critical sensing and electronic component technologies.

Pro forma revenue and net income have not been presented for Schatz, MagCanica, Micro-Tronics, Oldham, Spira, and the Other Acquisitions because the financial results are, individually and in the aggregate, not material to the condensed consolidated financial statements in any period presented.

Note 4. Revenue

The Company disaggregates revenue based on the method of measuring satisfaction of the performance obligation either at a point in time or over time. Additionally, the Company disaggregates revenue based on the end market where products and services are transferred to the customer. The Company’s principal operating segments and related revenue are discussed in “Note 5. Segment Information.”

Disaggregation of Revenue

Disaggregated revenue satisfied at a point in time and over time was as follows:

Disaggregated revenue by end market was as follows:

Contract Balances

Contract assets and contract liabilities were as follows:

Contract assets increased primarily due to new contract awards and timing of work performed resulting in progress toward completion and revenue recognition. This increase was partially offset by progress and contractual billings that reduced previously recognized contract asset balances. Contract liabilities decreased primarily as a result of revenue recognized upon completion of performance obligations, including the achievement of contractual milestones and fulfillment of orders during the period. This decrease was partially offset by advance payments received on new and existing contracts. For the nine months ended September 30, 2026 and 2025, revenue recognized from contract liabilities at the beginning of the period was$22,359 and$18,492, respectively.

Note 5. Segment Information

The Company hastwo reportable segments, Electronic Components and Mechanical Components. The Company’s segment reporting structure is consistent with how the Chief Operating Decision Maker ("CODM") reviews the business, makes investment and resource-allocation decisions, and assesses operating performance.

The Company’s CODM is its Chief Executive Officer. The CODM evaluates the performance of the segments and allocates resources to them based on segment adjusted earnings before interest, taxes, depreciation and amortization adjusted for other non-cash or non-recurring items (“Segment Adjusted EBITDA”) that management believes are not reflective of the Company’s ongoing core operations.

Information on the Company’s two reportable segments, Electronic Components and Mechanical Components, was as follows:

(1)

Represents cost of revenue adjusted to exclude depreciation and amortization of inventory step-up from acquisitions.

(2)

Represents selling, general and administrative expenses adjusted to exclude depreciation, transaction and other deal related expenses, acquisition and integration costs, restructuring related costs, and share-based compensation expense and certain related employer payroll taxes.

(3)

Represents miscellaneous income and expense such as foreign currency gains and losses and other income.

The following table provides a reconciliation of Segment Adjusted EBITDA to Net income before income taxes for the periods presented:

(1)

Includes$7,533 for employer taxes related to vested restricted stock units for the nine months ended September 30, 2026.

(2)

Includes$13,277 of expense related to the Convertible-Related Tax Receivable Agreement for the nine months ended September 30, 2026, and$12,000 of expense related to the Jacksonville Business matter for the three and nine months ended September 30, 2026.

Total assets by reportable segment were as follows:

Capital expenditures by reportable segment were as follows:

Prepaid expenses and other current assets consisted of the following:

Accrued expenses and other current liabilities consisted of the following:

Note 11. Debt

Debt consisted of the following:

2025 Credit Agreement

The Company's debt arrangements consist of the senior secured term loans (the "2025 Term Loan"), a senior secured revolving credit facility with a borrowing capacity of $400,000 (the “2025 Revolver”), and a delayed draw term loan with commitments of$201,000 (the “2025 DDTL”). The Company may draw on the 2025 DDTL until February 26, 2027.

In February 2025, the proceeds from the 2025 Term Loan were used to repay all outstanding instruments under the Company’s prior credit facilities. As a result of the extinguishment of such debt, the Company recorded a loss on extinguishment of debt of$15,535, which is included within Interest expense, net for the nine months ended September 30, 2025.

In April 2026, the Company used $946,000 of the net IPO proceeds to prepay a portion of the 2025 Term Loan. In June 2026, the Company amended the 2025 Credit Agreement to reduce theapplicable interest rate margin by 25 basis points, reduce the available commitments on the 2025 DDTL from $250,000 to$201,000, and amend the prepayment schedule such that the outstanding principal amounts are due in full at maturity. Following the amendment, there were no amounts outstanding under the 2025 DDTL. The fees incurred related to the partial prepayment and subsequent amendment were not material and are included within Interest expense, net for the nine months ended September 30, 2026. The Company recorded a loss on extinguishment of debt of$11,447, which is included within Interest expense, net for the nine months ended September 30, 2026.

As of September 30, 2026, there was no outstanding balance on the 2025 Revolver and$3,716 of letters of credit were utilized, resulting in an available borrowing capacity of$396,284 on the 2025 Revolver. As of September 30, 2026, the Company hadnot borrowed against the amended 2025 DDTL. As of December 31, 2025, there wasno outstanding balance on the 2025 Revolver and the Company had borrowed $24,000 against the 2025 DDTL.

Commitment Fees

The Company is subject to commitment fees, payable quarterly in arrears, on the unused portion of its revolving credit commitments and the undrawn capacity on its delayed draw term loan. Commitment fees were not material for the three and nine months ended September 30, 2026 and 2025, and are included within Interest expense, net in the Condensed Consolidated Statements of Operations.

Interest Rate Hedges

In April 2025, the Company entered into interest rate collar arrangements as an economic hedge to a portion of the Company’s outstanding debt. The collars have a cap rate of 5.0% and floor rates ranging from 1.9% to 2.5%. As of September 30, 2026 and December 31, 2025, the notional amount of the interest rate collars was$1,779,000 and $1,791,000, respectively. The interest rate collars terminate in December 2028.

The fair value as of September 30, 2026 was$10,323, which is included within Other assets. The fair value as of December 31, 2025 was $2,474, which is included within Other long-term liabilities. The change in fair value was$8,160 and$1,489 for the three months ended September 30, 2026 and 2025, respectively, and$12,797 and$(4,281) for the nine months ended September 30, 2026 and 2025, respectively, which is included within Interest expense, net.

Note 12. Commitments and Contingencies

Asset Retirement Obligations

The Company has asset retirement obligations (“AROs”) that are conditional upon certain events.

These AROs generally include the removal and disposition of non-friable asbestos. The facilities that contain non-friable asbestos are generally maintained in place, and under applicable environmental and workplace safety requirements, removal and disposal is generally required only if these materials are disturbed in connection with a major renovation, demolition, or other disposal activity, or if conditions otherwise require abatement under applicable law. The Company has not recorded a liability as of September 30, 2026, because the Company has no current plans for activities that would trigger disturbance and does not currently believe there is a reasonable basis for estimating a date or range of dates for major renovation or demolition of these facilities. In reaching this conclusion, the Company considered the historical performance of each facility and has taken into account factors such as planned maintenance, asset replacements, and upgrades, which, if conducted as in the past, can extend the physical lives of the facilities indefinitely. The Company also considered the possibility of changes in technology and risk of obsolescence in arriving at its conclusion. The Company will continue to evaluate these conditional obligations each reporting period and will record a liability when the fair value becomes reasonably estimable, including when the timing of settlement becomes reasonably estimable.

Additionally, the Company leases various properties under contracts that give the lessor the right to make the determination as to whether the lessee must return the premises to their original condition, except for normal wear and tear. The Company does not normally make substantial modifications to leased property, and many of the Company's leases either require lessor approval of planned improvements or transfer ownership of such improvements to the lessor at the termination of the lease. Historically, the Company has not incurred significant costs to return leased premises to their original condition.

Environmental Costs

The Company has certain liabilities associated with potential obligations to perform environmental remediation. As of September 30, 2026 and December 31, 2025, the accruals related to these obligations were$50,749 and$51,291, respectively, and are included within Accrued expenses and other current liabilities and Other long-term liabilities on the Condensed Consolidated Balance Sheets.

Moosup

The Company has certain obligations related to a former manufacturing facility in Moosup, Connecticut, that was sold to TD Development, LLC ("TD") in 2014. At the time of sale, TD assumed contractual and statutory responsibility for the environmental investigation and remediation work required at this site (subject to a cost-sharing arrangement). In September 2021, TD’s principal filed for personal bankruptcy protection, and during the course of that bankruptcy proceeding, the Company has learned that neither TD nor its principal is expected to have the means to undertake the investigation, remediation and abatement of the site. The Company has filed an objection to the issuance of a discharge in the bankruptcy proceeding.

In 2024, a settlement agreement with TD and related parties was signed, which provided the Company with access to its former facility to update the environmental condition assessment of the property and remaining remediation efforts required, formalize the Company's oversight of the investigation and remediation activities with the Connecticut Department of Energy and Environmental Protection (“CT DEEP”) and enable such investigation and remediation to be performed to a commercial/industrial standard rather than the more stringent residential standard. Under this settlement agreement, the Company will undertake the investigation, remediation and abatement of the site, with a modest contribution from TD’s principal. The Company engaged an environmental consultant to gather the appropriate data to calculate a range for the potential environmental obligation. The environmental consultant provided an estimate of the costs that are likely to be incurred in connection with these environmental investigation and remediation activities.

As of September 30, 2026 and December 31, 2025,$44,784 and $45,015, respectively, were accrued for these environmental investigation and remediation activities in Other long-term liabilities. The aggregate undiscounted amount has been accrued because it represents the Company’s best estimate of the cost, but the timing of payments is not considered to be fixed and reliably determinable. There can be no assurance that this matter would not have an adverse impact on our business, financial condition, results of operations and/or cash flows.

Bloomfield

The Company has the responsibility for environmental investigation and remediation at its Bloomfield campus as may be required under the Connecticut Transfer Act and other environmental laws and it continues the effort to define the scope of the remediation that will be required by the CT DEEP. This investigation and remediation process will take many years to complete.

As of September 30, 2026 and December 31, 2025, the Company had$5,005 and $5,003, respectively, accrued for these environmental investigation and remediation activities, a portion of which is included in Accrued expenses and other current liabilities and the remaining balance is included in Other long-term liabilities. Although it is reasonably possible that additional costs will be paid in connection with the resolution of this matter, the Company is unable to estimate the amount of such additional costs, if any, at this time. The following represents estimated future payments for the undiscounted environmental investigation and remediation liability related to the Bloomfield campus as of September 30, 2026:

Other Matters

The Company is subject to commercial matters and legal proceedings and claims that arise in the normal course of business. While the outcome of these matters cannot be predicted with certainty, the Company does not have any knowledge of any such matters that would have a material adverse effect on the condensed consolidated financial statements, except as disclosed below.

Commercial Commitments

In November 2024, a manufacturing business in Jacksonville, Florida (the “Jacksonville Business”) that is not part of the Arxis Businesses, was divested to a third party. Following the divestiture, the Company remained a guarantor of certain performance obligations arising under a long-term customer contract to which the Jacksonville Business is a party, pursuant to a guarantee agreement between the Company and such customer that predates the divestiture. The term of the contract covered by the guarantee ends in December 2028. There is no limitation to the maximum potential future liabilities under this guarantee; however, the Company has a right to indemnification from the Jacksonville Business against such losses that may arise from any failure of the Jacksonville Business to perform under the contract. Such indemnification right includes a monetary cap of $10,000, subject to customary exceptions. The Company may also have other rights or claims, at law or in equity, in connection with any failure by the Jacksonville Business to perform under the contract.

The customer has notified the Company of concerns regarding performance of the contract by the Jacksonville Business and alleged that it has incurred damages of$48,345 related to non-performance of the contract and indicated that its alleged damages may exceed this amount. The customer has requested that the Company fulfill its obligations under the guarantee. As of September 30, 2026, the Company has accrued$21,000 in the aggregate in respect of this matter, including incremental expense of $12,000 for the three months ended September 30, 2026 within Selling, general and administrative expenses in the Condensed Consolidated Statements of Operations. As of December 31, 2025, the Company had accrued$9,000.

As a response, in January 2026, the Company commenced litigation to seek to cause the Jacksonville Business to perform the contract. The Company may incur additional loss with respect to this matter pursuant to the guarantee if the customer and the Jacksonville Business do not resolve their dispute regarding the contract or if the Company is unsuccessful in causing the Jacksonville Business to perform the contract.

The Company may incur an additional loss in excess of the amount accrued, but no such loss is estimable at this time due to, among other things, the fact that the dispute raises difficult legal and factual issues and is subject to many uncertainties and complexities. Separately, as discussed above, insofar as any such amounts are asserted against the Company pursuant to the terms of the guarantee, the Company intends to exercise all of its rights and remedies against the Jacksonville Business in respect thereof, including seeking indemnification and pursuing any potential remedies. Any proceeds received will not be recognized until realization and could be in a reporting period subsequent to the period in which any loss in respect of the guarantee is probable and estimable.

The Company has certain liabilities related to a helicopter crash where the helicopter utilized the Company’s K-Max blades. The Company is named in litigation seeking damages for loss of property and business interruption.

The Company has accrued $17,388 representing its estimate of the probable loss associated with the loss of property and business interruption claims. This amount is included in Accrued expenses and other current liabilities as of September 30, 2026, and Other long-term liabilities as of December 31, 2025. The Company, in coordination with its insurance carriers, estimates that a portion of the liability on the loss of property and business interruption claims is recoverable under insurance coverage amounts. Accordingly, the Company recognized a receivable of $7,779 for the estimated insurance recovery, which is included in Other current assets as of September 30, 2026, and Other assets as of December 31, 2025. During the third quarter of 2026, based on an agreement to pay $6,300 related to this matter and the expected timing of resolution of the remaining items on appeal, the Company reclassified the liability and related receivable from noncurrent to current. These reclassifications did not change the amounts recorded, and the Company made no changes to its estimates associated with the claims.

The claims related to loss of property and business interruption proceeded to trial and there was a verdict awarding $22,000 to theplaintiff. Additional pre-judgment and post-judgment interest will apply. The jury found there was no design defect in the K-Max blades. The Company, along with the insurance carriers, has appealed the verdict.

Other than the above matters, the Company is not involved in any pending, material legal proceedings other than routine legal proceedings occurring in the ordinary course of business.

Note 13. Income Taxes

The Company's effective income tax rate was 30.1% for the three months ended September 30, 2026, compared to 122.5% for the three months ended September 30, 2025. The Company's effective income tax rate was 29.5% for the nine months ended September 30, 2026, compared to 165.1% for the nine months ended September 30, 2025.

The change in the effective tax rate for the three and nine months ended September 30, 2026 and 2025 was primarily due to IPO-related items, including nondeductible share-based compensationand the establishment of deferred tax assets ($1,400 discrete tax benefit) in 2026, and primarily due to the mix of earnings and losses across jurisdictions subject to different tax rates in 2025.

The effective tax rates for the three and nine months ended September 30, 2026 and 2025 differed from the U.S. federal statutory tax rate of 21% primarily due to IPO-related items, including nondeductible share-based compensation in 2026, and primarily due to the mix of earnings and losses across jurisdictions subject to different tax rates in 2025.

Based on its analysis, the Company’s pre-IPO tax attribute carryforwards, including net operating losses, tax credits, and disallowed interest under IRC Section 163(j) are subject to the lesser of the separate return limitation year rules or Section 382 annual limitation. The Company does not expect these limitations to cause any tax attributes to expire before they are utilized and thus does not expect to establish any additional valuation allowances.

The Company has a valuation allowance with respect to a portion of its disallowed interest under IRS Section 163(j). Based on the current earnings, it is reasonably possible that, within the next twelve months, sufficient sources of income may become available to support the release of a portion of the valuation allowance related to disallowed interest under IRS Section 163(j). Any such release of the valuation allowance would result in the recognition of certain deferred tax assets and a decrease to income tax expense for the period the release is recognized.

The Company recognized certain tax effects associated with the Convertible-Related Tax Receivable Agreement entered into in connection with the Reorganization and IPO. Refer to “Note 14. Equity” for additional information.

Note 14. Equity

Prior to the Reorganization and IPO, the Company’s outstanding equity consisted of Class A-1 Units and Class A-2 Units (collectively, “Class A Units”), Class B Units (incentive units), and Growth Participation Units and Value Creation Bonus Units (equivalent Class B Units) of Arcline Engineered Polymer Topco, L.P., Hawkeye TopCo, L.P., Connector TopCo, L.P., and Ovation TopCo, L.P.

Upon the completion of the Reorganization, as described in “Note 1. Organization and Nature of Operations,” the Company’s outstanding equity units were converted into Class A common stock and Class B common stock. As consideration for the Reorganization, the Company issued (i)340,677 shares of Class B common stock, par value $0.01 (“Class B common stock”), and 23,083 shares of Class A common stock, par value $0.01 (“Class A common stock”), to the holders of Class A units and vested equity units of the Arxis Businesses and (ii)10,548 restricted shares of, or restricted units with respect to, Class A common stock to holders of unvested equity units of the Arxis Businesses, which awards are subject to forfeiture conditions. In addition, the Company issuedone share of convertible common stock to Arcline.

Class A, Class B, and Class C common stock have the same economic rights, including rights to dividends and distributions upon liquidation. Class B common stock is convertible into Class A common stock on a one-for-one basis at the option of the holder, and will automatically convert on a one-for-one basis upon the earliest to occur of (i) a transfer of such shares other than as permitted under the Company's amended and restated certificate of incorporation, (ii) such shares coming to be held by a person other than a permitted transferee, (iii) the approval of the holders of a majority of the outstanding Class B common stock, voting separately as a class, or (iv) the first business day after which the outstanding Class B common stock represents less than 10% of the total outstanding common stock and the Sponsor (together with its permitted transferees) beneficially owns less than 35% of the Class B common stock originally issued to the Sponsor in connection with the IPO, in each case as further described in the Company's amended and restated certificate of incorporation.

Class A common stockholders are entitled toone vote per share, Class B common stockholders are entitled to 20 votes per share, and Class C common stockholders are entitled tono votes per share.

Convertible Common Stock

In connection with the Reorganization, the Company issued one share of convertible common stock to Arcline pursuant to the Advisory and Consulting Agreement. The convertible common stock is convertible into shares of Class B common stock (or Class A common stock if no Class B common stock is outstanding at the time of such conversion) representing the product of (i)1.25% of the Company’s fully diluted capital stock outstanding at the time of conversion multiplied by (ii) two times the value of one minus the quotient obtained by dividing the IPO price per share of $28.00 ("IPO Price") by the stock price per share at the time of conversion. The convertible common stock is convertible at the holder’s option from the fifth anniversary of the IPO (April 17, 2031) until the tenth anniversary of the IPO (April 17, 2036), provided that the price of Class A common stock must equal at least two times the IPO Price prior to conversion. If the trading price of Class A common stock has been less than 1.5 times the IPO Price for at least 75% of trading days during the twelve-month period ending immediately prior to the 11-year anniversary of the IPO (April 17, 2037), any outstanding convertible common stock will be automatically forfeited. If the convertible common stock is forfeited for any reason prior to the fifth anniversary of the IPO (April 17, 2031), including because Arcline ceases performing services under the Advisory and Consulting Agreement, no conversion will occur. After the 12-year anniversary of the IPO (April 17, 2038), the Company may, at the election of the disinterested directors at that time, redeem any outstanding convertible common stock for an amount of Class A common stock equal to the excess of three times the IPO Price, on an as-converted basis, regardless of whether any other conditions to conversion have been satisfied.

Prior to satisfaction of the conversion conditions above, the holder is entitled to vote, to consent, to receive dividends, if any, to receive notices as stockholders with respect to any meeting of stockholders and to exercise any rights whatsoever on an as-converted basis. See "Note 15. Share-Based Arrangements" for measurement and recognition under ASC 718.

In connection with the issuance of the convertible common stock, the Company entered into the Convertible-Related Tax Receivable Agreement whereby the Company will pay Arcline 85% of the cash tax savings realized by the Company with respect to the compensation deduction resulting from the transfer of the convertible common stock in respect of the services to be provided under the Advisory and Consulting Agreement and the related election under Section 83(b) of the Internal Revenue Code. As of September 30, 2026, the Company accrued$13,277 related to this arrangement.

Note 15. Share-Based Arrangements

Restricted Shares and Restricted Stock Units

Prior to the Reorganization, Arcline Engineered Polymer Topco, L.P., Hawkeye TopCo, L.P., Connector TopCo, L.P., and Ovation TopCo, L.P. established Management Equity Plans (the “ME Plans”), Growth Participation Plans (“GPP”) and the Value Creation Bonus (“VCB”) Plan, under which the Board of Directors of each entity’s plan had the authority to grant Management Incentive Units (“MIUs”), Growth Participation Units (“GPUs”) and VCBs, respectively.

In connection with the Reorganization, outstanding unvested equity awards were converted into RSAs or RSUs with respect to Class A common stock. The RSAs and RSUs are subject to service-based vesting conditions. Any performance-based vesting conditions that previously existed were eliminated upon the Reorganization. The Company accounted for the conversion of the equity awards as a modification under ASC 718 and recognized incremental expense for vested awards of$73,103 for the nine months ended September 30, 2026 within Selling, general and administrative expenses in the Condensed Consolidated Statements of Operations.

Vesting for the RSAs generally occurs as follows: (i) the portion subject to the original service-based vesting condition will continue to vest over the respective original vesting schedule, and (ii) the portion previously subject to the performance-based vesting condition will vest over three years beginning on the later of the one-year anniversary of the IPO or the three-year anniversary of the applicable vesting commencement date. Vesting for the RSUs, which were previously subject to performance-based vesting conditions, will vest overtwo years beginning on the one-year anniversary of the IPO.

As of September 30, 2026, the Company had 10,133 unvested RSAs and RSUs outstanding. Total unrecognized compensation expense related to the unvested RSAs and RSUs issued was$219,995, which is expected to be recognized over a weighted-average period of 2.3 years.

Convertible Common Stock

The grant-date fair value of the convertible common stock was$129,680, which is recognized as compensation expense on a straight-line basis over the derived service period offive years, based on the timing to achieve the outcome under the optimal scenario determined by the valuation. The Company recognized$6,484 and$11,887 of share-based compensation expense for the three and nine months ended September 30, 2026, respectively. As of September 30, 2026, there was$117,793 of total unrecognized compensation expense related to the convertible common stock, which is expected to be recognized over 4.5 years.

2026 Omnibus Plan

In connection with the IPO, the Company’s board of directors and stockholders approved the Arxis, Inc. 2026 Omnibus Incentive Plan (the “2026 Omnibus Plan”) for the purpose of granting long-term equity incentive awards to the Company’s employees, consultants and non-employee directors. The 2026 Omnibus Plan authorizes the grant of stock options, stock appreciation rights, restricted stock, restricted stock units, performance awards, and other stock-based awards. A total of 58,998 shares of the Company’s Class A common stock were reserved for issuance under the 2026 Omnibus Plan. Starting in 2027, the number of shares available for issuance under the 2026 Omnibus Plan will be increased automatically on the first day of each fiscal year, by a number of shares of Class A common stock equal to the lesser of (i)5% of the outstanding number of shares of all classes of common stock (on a fully diluted basis) on the last day of the immediately preceding fiscal year, and (ii) a lower number of shares as may be determined by the compensation committee.

As of September 30, 2026,43,165 shares remained available for future issuance.

Employee Stock Purchase Plan

In connection with the IPO, the Company's board of directors and stockholders approved the Arxis, Inc. Employee Stock Purchase Plan (the "ESPP") for the purpose of providing the Company's employees with an opportunity to acquire an interest in the Company through the purchase of shares of Class A common stock. The ESPP has two components, one which is intended to qualify as an "employee stock purchase plan" under Section 423 of the Internal Revenue Code and one which is not intended to so qualify.

The ESPP enables eligible employees to purchase shares of Class A common stock through accumulated payroll deductions at a discounted price equal to 85% of the fair market value of a share of Class A common stock on the purchase date. Each offering period is expected to have a duration of six months, and the maximum number of shares that may be purchased by a participant during a single offering period may not exceed 5 shares.

A total of 3,694 shares of Class A common stock were reserved for issuance under the ESPP. The number of shares reserved for issuance under the ESPP will increase on the first day of each fiscal year following April 17, 2026 by a number equal to the lesser of (i)1.00% of the outstanding number of shares of all classes of common stock on the last day of the immediately preceding fiscal year and (ii) such number of shares determined by the compensation committee in its discretion, subject to a maximum of 100,000 shares. As of September 30, 2026,3,694 shares remained available for future issuance under the ESPP.

As of September 30, 2026, no amounts have been withheld on behalf of employees for a future purchase under the ESPP andno shares of Class A common stock have been purchased under the ESPP as the first offering period had not yet commenced.

Note 16. Net Income (Loss) Per Share

Prior to the Reorganization and IPO, all earnings were attributable to the historical equity holders of the Arxis Businesses. As the Company's historical ownership did not have common stock, and the capital structure before and after the Reorganization and IPO are not comparable, the presentation of net income (loss) per share for the periods prior to the IPO is not meaningful and not presented herein.

See "Note 2. Summary of Significant Accounting Policies" for a description of the Company's net income (loss) per share methodology, including the treatment of the Company's convertible common stock as a participating security. Because Class A common stock, Class B common stock, and Class C common stock have identical rights, except with respect to voting, basic and diluted net income (loss) per common share are presented on a combined basis for these classes of common stock.

The following table sets forth the computation of basic and diluted net income (loss) per common share for the periods presented (in thousands, except per share amounts):

(1)

The net income attributable to the period prior to the Reorganization and IPO represents the net income for three months ended March 31, 2026.

(2)

Represents amounts for the six-month period from April 1, 2026 to September 30, 2026, which represents the period during which the Company hadcommon stock outstanding.

(3)

Weighted-average common shares outstanding is calculated based on the shares issued in connection with the Reorganization reflected as outstanding starting on April 1, 2026 and the shares issued in the IPO starting on April 16, 2026.

Note 17. Employee Retirement Plans

Pension Plans

The Company sponsors certain defined benefit pension plans. Certain of these defined benefit pension plans are non-contributory and frozen and therefore no additional service costs are incurred for those plans. Other defined benefit pension plans maintained by the Company’s operating subsidiaries continue to accrue benefits for eligible participants in accordance with the respective plan provisions. Net periodic pension (income) cost was not material for the three and nine months ended September 30, 2026 and 2025.

Contributions to the Company’s defined benefit pension plans were not material for the three and nine months ended September 30, 2026 and 2025. Contributions to the defined benefit pension plans are not expected to be material in 2026.

Deferred Compensation Plans

The Company maintains a non-qualified deferred compensation plan for certain of its employees. In 2026, the non-qualified deferred compensation plan was frozen to new employee and employer contributions, with existing balances continuing to accrue earnings based on participants' investment elections. Generally, participants have the ability to defer a certain amount of their compensation, as defined in the agreement. The deferred compensation liability will be paid out either upon retirement or as requested based upon certain terms in the agreements and in accordance with Internal Revenue Code Section 409A. The Company holds investments in company-owned life insurance policies which are recorded at cash surrender value (Level 2). The investments are included in Other assets on the Condensed Consolidated Balance Sheets and were$33,913 and $32,728, as of September 30, 2026 and December 31, 2025, respectively. The liabilities under this plan were$2,403 and $2,566, which are included in Accrued expenses and other current liabilities, and$14,486 and $16,490, which are included in Other long-term liabilities on the Condensed Consolidated Balance Sheets, as of September 30, 2026 and December 31, 2025, respectively.

Defined Contribution Plans

The Company sponsors defined contribution plans covering substantially all eligible employees. The plans permit participants to make elective deferrals, with the Company providing matching contributions. Company contributions vary depending on the date of hire, with the majority of employees eligible for employer matching on a portion of their contributions. Employer contributions to the defined contribution plans were$2,735 and$2,420 for thethree months ended September 30, 2026 and 2025, respectively and$8,613 and$8,612 for the nine months ended September 30, 2026 and 2025, respectively.
