INTERFACE INC

NOTE 1 –SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

References in this Quarterly Report on Form 10-Q to “Interface,” “the Company,” “we,” “our,” “ours” and “us” refer to Interface, Inc. and its subsidiaries or any of them, unless the context requires otherwise.

As contemplated by the Securities and Exchange Commission (the “Commission”) instructions to Form 10-Q, the following footnotes have been condensed and, therefore, do not contain all disclosures required in connection with annual financial statements. Reference should be made to the Company’s year-end financial statements and notes thereto contained in its Annual Report on Form 10-K for the fiscal year ended December 28, 2025, as filed with the Commission.

The financial information included in this report has been prepared by the Company. In the opinion of management, the financial information included in this report contains all adjustments necessary for a fair presentation of the results for the interim periods. All such adjustments are of a normal recurring nature unless otherwise disclosed. Nevertheless, the results shown for interim periods are not necessarily indicative of results to be expected for the full year. The December 28, 2025, consolidated condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States (“GAAP”).

The nine-month period ended October 4, 2026 includes 40 weeks and the nine-month period ended September 28, 2025 includes 39 weeks. The three-month periods ended October 4, 2026 and September 28, 2025 both include 13 weeks.

Risks and Uncertainties

Ongoing global economic challenges including but not limited to inflation, government-imposed tariffs, supply chain disruptions, disruptions in global energy markets, the Russia-Ukraine war and conflicts in the Middle East, and slow market conditions in certain parts of the globe could cause economic uncertainty and volatility. The Company considered these impacts and subsequent general uncertainties and volatility in the global economy on the assumptions and estimates used herein. These uncertainties could result in a future material adverse effect to the amounts reported within the Company’s consolidated condensed financial statements if actual results differ from these estimates.

Accounting Policies

The Company’s accounting policies are set forth in its most recently filed Annual Report on Form 10-K. There have been no material changes to the Company’s accounting policies during the first nine months of 2026. During the first quarter of 2026, the U.S. Supreme Court ruled that tariffs previously paid under the International Emergency Economic Powers Act (“IEEPA”) were invalid. The Company elected to apply the gain contingency model to account for potential tariff refunds previously paid under the IEEPA. Under this model, a gain contingency is not recognized in the financial statements until the gain is realized or realizable.

During the second quarter of 2026, the Company recognized approximately $15.6 million in refunds for tariffs previously paid under the IEEPA, which were recognized as a reduction to cost of sales in the consolidated condensed statements of operations. In connection with these tariff refunds, the Company also recorded approximately $0.5 million of interest income, presented as a reduction to interest expense, net in the consolidated condensed statements of operations. As of October 4, 2026, any outstanding requests for IEEPA tariff refunds are not material.

Recently Issued Accounting Pronouncements– Not Yet Adopted

In September 2025, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2025-06 - “Intangibles--Goodwill and Other--Internal Use Software (Subtopic 350-40)”. This ASU amends the accounting for internal-use software costs by removing reference to prescriptive and sequential software development stages used to evaluate capitalizable costs. The ASU requires entities to consider whether significant uncertainties associated with development activities have been resolved prior to capitalization of software costs and aligns disclosure requirements with Accounting Standards Codification (“ASC”) 360, “Property, Plant, and Equipment”. The new guidance in ASU 2025-06 is effective for annual periods beginning after December 15, 2027, and interim periods within those annual reporting periods, and may be applied prospectively, retrospectively, or using a modified retrospective approach. Early adoption is permitted. The Company is currently evaluating the impact of this ASU on its consolidated financial statements.

In November 2024, the FASB issued ASU 2024-03, “Income Statement Reporting--Comprehensive Income-- Expense Disaggregation Disclosures (Subtopic 220-40)”. This ASU requires public entities to provide additional footnote disclosures to disaggregate the cost and expense line items presented in the income statement into specific categories including (a) purchases of inventory; (b) employee compensation; (c) depreciation; and (d) intangible asset amortization. The ASU also requires qualitative disclosure of other relevant expense categories not separately disclosed, the total amount of selling expenses, and the definition of selling expenses in annual reporting periods. The new guidance in ASU 2024-03 is effective for annual periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the impact of this ASU on its consolidated financial statements.

NOTE 2 –REVENUE RECOGNITION

The Company generates revenue from sales of modular carpet, resilient flooring, rubber flooring, and other flooring-related material, and from the installation of carpet and other flooring-related material. A summary of these revenue streams, as a percentage of consolidated net sales, for the three and nine months ended October 4, 2026 and September 28, 2025 is as follows:

For the three and nine months ended October 4, 2026 and September 28, 2025, revenue by material market segment as a percentage of consolidated totals is as follows:

NOTE 3 –INVENTORIES

Inventories are summarized as follows:

NOTE 4 –EARNINGS PER SHARE

The Company computes basic earnings per share (“EPS”) by dividing net income by the weighted average common shares outstanding, including participating securities outstanding, during the period as discussed below. Diluted EPS reflects the potential dilution beyond shares for basic EPS that could occur if securities or other contracts to issue common stock were exercised, converted into common stock or resulted in the issuance of common stock that would have shared in the Company’s earnings.

The Company includes all unvested stock awards that contain non-forfeitable rights to dividends or dividend equivalents, whether paid or unpaid, in the number of shares outstanding for basic EPS as these awards are considered participating securities. Unvested share-based awards of restricted stock are paid dividends equally with all other shares of common stock and are considered participating securities. As a result, the Company includes all outstanding restricted stock awards during the period in the calculation of basic and diluted EPS. As of October 4, 2026, there were no unvested restricted stock awards. Any unvested share-based awards considered non-participating securities (restricted share units and performance shares) are included in diluted EPS calculations when the inclusion of these shares would be dilutive. The following table shows the computation of basic and diluted EPS:

(1) Income attributable to participating securities for the nine-month period ended September 28, 2025 wasnot material.

NOTE 5 –LONG-TERM DEBT

Long-term debt consisted of the following:

(1) Represents the weighted average rate of interest for borrowings under the Syndicated Credit Facility without the effect of debt issuance costs.

(2) The Syndicated Credit Facility also includes a multicurrency revolving loan facility up to $250 million.

Syndicated Credit Facility

The Company’s Syndicated Credit Facility (the “Facility”) provides to the Company U.S. denominated and multicurrency term loans and provides to the Company and certain of its subsidiaries a multicurrency revolving loan facility. Each of the Company’s material domestic subsidiaries guarantees the obligations of the Company under its Facility. The Facility matures December 3, 2030. At October 4, 2026, the Company had available borrowing capacity of $247.7 million under the revolving loan facility.

Interest on base rate loans is charged at varying rates computed by applying a margin depending on the Company’s consolidated net leverage ratio as of the most recently completed fiscal quarter. Interest on Secured Overnight Financing Rate (“SOFR”)-based and alternative currency loans is charged at varying rates computed by applying a margin over the applicable SOFR or alternative currency rate, depending on the Company’s consolidated net leverage ratio as of the most recently completed fiscal quarter. In addition, the Company pays a commitment fee per annum (depending on the Company’s consolidated net leverage ratio as of the most recently completed fiscal quarter) on the unused portion of the Facility.

Fees for commercial letters of credit are computed as a percentage of the amount available to be drawn under such letters of credit. Fees for standby letters of credit are charged at varying rates computed by applying a margin of the amount available to be drawn under such standby letters of credit, depending on the Company’s consolidated net leverage ratio as of the most recently completed fiscal quarter.

Under the Facility, the Company is required to make quarterly amortization payments on the term loan borrowings, which are due on the last day of the calendar quarter.

The Company is in compliance with all covenants under the Facility and anticipates that it will remain in compliance with the covenants for the foreseeable future.

Future Maturities

The aggregate maturities of borrowings outstanding at October 4, 2026 were as follows:

Total long-term debt in the consolidated condensed balance sheets includes a reduction for unamortized debt issuance costs, which are excluded from the maturities table above.

(1) The goodwill balance is allocated entirely to the AMS reportable segment.

(2) A portion of the goodwill balance is comprised of goodwill denominated in a foreign currency attributable to the nora acquisition.

The net carrying value of intangible assets other than goodwill was $48.6 million and $50.9 million at October 4, 2026 and December 28, 2025, respectively.

NOTE 10 –SEGMENT INFORMATION

The Company determines that an operating segment exists if a component (i) engages in business activities from which it earns revenues and incurs expenses, (ii) has operating results that are regularly reviewed by the chief operating decision maker (“CODM”) and (iii) has discrete financial information. Additionally, accounting standards require the utilization of a “management approach” to report the financial results of operating segments, which is based on information used by the CODM to assess performance and make operating and resource allocation decisions. The Company determined that it hastwo operating segments organized by geographical area – namely (a) Americas (“AMS”) and (b) Europe, Africa, Asia and Australia (collectively “EAAA”). The AMS operating segment includes the United States, Canada and Latin America geographic areas.

Pursuant to the management approach discussed above, the Company’s CODM, our chief executive officer, evaluates performance at the AMS and EAAA operating segment levels and makes operating and resource allocation decisions based on segment adjusted operating income (“AOI”). The CODM uses AOI to evaluate segment operating results compared to expectations. AOI is also used by the CODM to develop variable compensation targets and make capital spend decisions. AOI excludes restructuring, asset impairment, severance, and other, net, and nora purchase accounting amortization. Intersegment revenues for the three and nine months ended October 4, 2026, were $43.1 million and $106.2 million, respectively, and intersegment revenues for the three and nine months ended September 28, 2025, were $28.6 million and $92.4 million, respectively. Intersegment revenues are eliminated from net sales presented below since these amounts are not included in the information provided to the CODM.

The Company has determined that it hastwo reportable segments – AMS and EAAA, as each operating segment meets the quantitative thresholds defined in the accounting guidance.

The following table outlines information by reportable segment including net sales, significant segment expenses, and AOI. The table also includes a reconciliation to income before taxes for the three and nine months ended October 4, 2026 and September 28, 2025.

(1) Significant segment expense categories and amounts align with segment level information that is regularly provided to the CODM, included in the measure of segment profit, and considered to be significant. Amounts include allocation of corporate overhead and global support costs. Intersegment expenses are excluded.

(2) Adjusted cost of sales excludes purchase accounting amortization.

(3) Adjusted selling, general, and administrative expenses exclude restructuring, asset impairment, severance, and other, net.

NOTE 11 –SUPPLEMENTAL CASH FLOW INFORMATION

Supplemental cash flow information for the nine months ended October 4, 2026 and September 28, 2025 is presented in the following table:

See Note 7 entitled “Leases” for additional supplemental disclosures related to finance and operating leases.

NOTE 12 –INCOME TAXES

The Company determines its provision for income taxes for interim periods using an estimate of its annual effective tax rate (“AETR”) and records any changes affecting the estimated AETR in the interim period in which the change occurs, including discrete tax items.

During the nine months ended October 4, 2026, the Company recorded a total income tax provision of $38.4 million on pre-tax income of $152.6 million resulting in an effective tax rate of 25.2%, as compared to a total income tax provision of $18.1 million on pre-tax income of $109.8 million resulting in an effective tax rate of 16.5% during the nine months ended September 28, 2025. The increase in the effective tax rate for the nine months ended October 4, 2026 as compared to the nine months ended September 28, 2025, was primarily due to statutory tax rate changes requiring the remeasurement and adjustment of deferred taxes as discussed below partially offset by an increase in deductions related to foreign-derived income.

In July 2025, Germany enacted tax legislation to gradually reduce the corporate income tax rate. The current income tax rate of 15% is set to decrease by 1% annually beginning in 2028 reaching 10% by 2032. As a result of this change to tax rates, deferred tax assets and liabilities were remeasured using the new rates applicable to the periods in which the underlying temporary differences are expected to reverse. The remeasurement of the Company’s German deferred tax positions and other deferred tax adjustments resulted in a favorable deferred income tax benefit of $10.4 million for the nine months ended September 28, 2025.

On December 20, 2021, the Organization for Economic Co-operation and Development (“OECD”) published Pillar Two Model Rules defining the global minimum tax, which calls for the taxation of large corporations at a minimum rate of 15%. The OECD has since issued administrative guidance providing transition and safe harbor rules around the implementation of the Pillar Two global minimum tax. Many non-U.S. tax jurisdictions have enacted legislation to adopt the Pillar Two Model Rules beginning in 2024 (including the European Union Member States) or announced plans to enact legislation in future years. For fiscal year 2026, we expect to meet the Transitional Country-by-Country Reporting (“CbCR”) Safe Harbor rules for most jurisdictions and do not expect these provisions to have a material impact on the Company’s financial statements. We will continue to closely monitor ongoing developments and evaluate any potential impact on future periods.

In 2026, the OECD issued a Side-by-Side package (“SbS”) that simplifies Pillar Two, creates new safe harbors, fully exempts U.S. parent groups from two of the three top-up taxes, and extends the CbCR Safe Harbor through fiscal year 2027. In certain jurisdictions, local legislative action is needed to effectuate the SbS agreement and will be considered in our accounting estimate upon enactment.

As of October 4, 2026, the Company had accrued approximately $5.3 million for unrecognized tax benefits.

NOTE 13 –ITEMS RECLASSIFIED FROM ACCUMULATED OTHER COMPREHENSIVE LOSS

Amounts reclassified out of accumulated other comprehensive loss (“AOCL”), before tax, to the consolidated condensed statements of operations during the three and nine months ended October 4, 2026 and September 28, 2025 are reflected in the tables below:

NOTE 14 –COMMITMENTS AND CONTINGENCIES

From time to time, we are a party to legal proceedings, whether arising in the ordinary course of business or otherwise. For additional information see disclosures set forth in Note 17 to the consolidated financial statements included in Item 8 of the Annual Report on Form 10-K for the fiscal year ended December 28, 2025. There have been no material changes since December 28, 2025.

NOTE 15 –FAIR VALUE OF FINANCIAL INSTRUMENTS

Accounting standards establish a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure estimated fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1 measurements) and the lowest priority to unobservable inputs (level 3 measurements). The three levels of the fair value hierarchy under applicable accounting standards are described below:

Level 1 Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.

Level 2 Inputs to the valuation methodology include:

•quoted prices for similar assets in active markets;

•quoted prices for identical or similar assets in inactive markets;

•inputs other than quoted prices that are observable for the asset; and

•inputs that are derived principally from or corroborated by observable data by correlation or other.

Level 3 Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable.

A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

The following table presents the carrying values and estimated fair values, including the level within the fair value hierarchy, of certain financial instruments:

(1) Carrying values are presented gross, excluding the impact of unamortized debt issuance costs and including amounts presented as current liabilities on the consolidated condensed balance sheets.

(2) The carrying value of borrowings under the Facility approximates fair value as the Facility bears variable interest rates that are similar to existing market rates. The fair value of borrowings under the Facility is estimated using observable market rates.

The fair value of Company-owned life insurance is measured based on its readily determinable cash surrender value on a recurring basis.

Assets associated with the Company’s nonqualified savings plans are held in a rabbi trust and consist of investments in mutual funds and insurance contracts. The fair value of the mutual funds is derived from quoted prices in active markets. The fair value of the insurance contracts is based on observable inputs related to the performance measurement funds that shadow the deferral investment allocations made by participants in the nonqualified savings plans.
