Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying Unaudited Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. The year-end consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP. In the opinion of management, all estimates and adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three and six months ended June 30, 2024 are not necessarily indicative of the results that may be expected for the year ending December 31, 2024. This Quarterly Report on Form 10-Q/A should be read in conjunction with the consolidated financial statements and footnotes thereto included in L.B. Foster Company’s Annual Report on Form 10-K/A for the year ended December 31, 2023. In this Quarterly Report on Form 10-Q/A, references to “we,” “us,” “our,” and the “Company” refer collectively to L.B. Foster Company and its consolidated subsidiaries. Recently Issued Accounting Standards In November 2023, the FASB issued Accounting Standards Update 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” (“ASU 2023-07”), which requires enhanced disclosures regarding significant segment expenses that are regularly reviewed by the chief operating decision maker (“CODM”) and included in each reported measure of segment profit or loss, including an amount for “other segment items” by reportable segment and a description of its composition. ASU 2023-07 also requires entities to disclose the title and position of the CODM and an explanation of how the CODM uses reported measures of segment profit or loss to assess performance and allocate resources. The amendments are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024 with early adoption permitted. The Company expects ASU 2023-07 to only impact its disclosures with no impacts to its consolidated financial condition, results of operations, and cash flows. In December 2023, the FASB issued Accounting Standards Update 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”). ASU 2023-09 requires entities to disclose additional information with respect to the effective tax rate reconciliation and disaggregation of income tax expense and income taxes paid by jurisdiction. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the impact of ASU 2023-09, but expects this ASU to only impact its disclosures with no impacts to its consolidated financial condition, results of operations, and cash flows. Restatement of Previously Issued Unaudited Condensed Consolidated Financial Statements The Company identified an error related to the classification of the $3,477 gain on the sale of the former joint venture facility located in Magnolia, Texas, which sale was completed in the first quarter of 2024 (the “Magnolia Sale”) and reflected in the Company’s Unaudited Condensed Consolidated Statement of Operations for the six month period ended June 30, 2024 (the “Affected Period”). Upon completion of the Magnolia Sale, the Company recorded the $3,477 gain in “Other (income) expense - net” in the Unaudited Condensed Consolidated Statement of Operations. The Company had concluded that such classification was appropriate. However, in accordance with ASC 360-10-45-5, the $3,477 gain on the Magnolia Sale should have been recorded as a component of “Operating income” and not “Other (income) expense - net.” As a result of this classification error, “Operating income” was understated by $3,477 and “Other (income) expense - net” was overstated by $3,477 in the Company’s Unaudited Condensed Consolidated Statements of Operations for the six month period ended June 30, 2024. The Company also made other immaterial error corrections to its Unaudited Condensed Consolidated Statements of Operations for the six months ended June 30, 2024 (together with the Magnolia Sale adjustment, the “Restatement Adjustments”) and for the three months ended June 30, 2024, as well as for the three and six months ended June 30, 2023. The impact of these adjustments are shown in the tables below. Note only line items that were impacted by the Restatement Adjustments and immaterial error corrections are included below.

However, immaterial error corrections were made to the Consolidated Balance Sheet as of December 31, 2023 in the Company’s Annual Report on Form 10-K/A as filed on November 1, 2024, as shown in the table below.

Segment Reporting [Abstract]
Business Segments	Business Segments The Company is a global technology solutions provider of engineered, manufactured products and services that builds and supports infrastructure. The Company’s segments represent components of the Company (a) that engage in activities from which revenue is generated and expenses are incurred, (b) whose operating results are regularly reviewed by the Chief Operating Decision Maker (“CODM”), who uses such information to make decisions about resources to be allocated to the segments, and (c) for which discrete financial information is available. Operating segments are evaluated on their segment profit contribution to the Company’s consolidated results. Other income and expenses, interest, income taxes, and certain other items are managed on a consolidated basis. The Company’s segment accounting policies are described in Note 2 Business Segments of the Notes to the Company’s Consolidated Financial Statements contained in its Annual Report on Form 10-K/A for the year ended December 31, 2023. The Company is organized and operates in two reporting segments: Rail, Technologies, and Services (“Rail”), and Infrastructure Solutions (“Infrastructure”). Effective for the quarter and year ended December 31, 2023, the Company made certain organizational changes that led to the conclusion that it will operate under two reporting segments as opposed to the three reporting segments it has operated under historically. As such, the Company has restated segment information for the historical periods presented herein to conform to the current presentation. The Infrastructure business comprises both the historic Precast Concrete Products and Steel Products and Measurement (since renamed “Steel Products”) reporting segments. The operating results of the Company’s reportable segments were as follows for the periods presented: Three Months Ended Three Months Ended Net Sales Segment Operating Income Net Sales Segment Operating Income Rail, Technologies, and Services $ 85,594 $ 5,501 $ 91,616 $ 6,971 Infrastructure Solutions 55,202 3,623 56,418 2,773 Total $ 140,796 $ 9,124 $ 148,034 $ 9,744 Six Months Ended Six Months Ended Net Sales Segment Operating Income Net Sales Segment Operating Income (As Restated) Rail, Technologies, and Services $ 168,217 $ 12,279 $ 156,000 $ 9,365 Infrastructure Solutions 96,899 2,235 107,522 2,433 Total $ 265,116 $ 14,514 $ 263,522 $ 11,798 Segment operating income, as shown above, includes allocated corporate operating expenses. Allocated corporate operating expenses include costs associated with central services such as quality, logistics, environmental health and safety, information technology, insurance, and human resources. Other corporate functional costs that are associated with the operating segments are also allocated to the segments such as finance, marketing, credit and collections, and treasury functions. Operating expenses related to corporate headquarter functions were allocated to each segment based on segment headcount, revenue contribution, or activity of the business units within the segments, based on the corporate activity type provided to the segment. Management believes the allocation of corporate operating expenses provides an accurate presentation of how the segments utilize corporate support activities. This provides the CODM meaningful segment profitability information to support operating decisions and the allocation of resources. The accounting policies of the reportable segments are the same as those described in the summary of significant accounting policies found in Note 1 Significant Accounting Policies of the Notes to the Company’s Consolidated Financial Statements contained in its Annual Report on Form 10-K/A for the year ended December 31, 2023. During the quarter, the Company sold an ancillary property within the Steel Products business unit for total proceeds of $1,300 generating an $815 gain on sale recorded in “Cost of goods sold” for the three months ended June 30, 2024 which has been included in the Infrastructure segment’s operating income. Certain corporate costs are separately managed on a consolidated basis and are not allocated to the operating segments. These corporate costs include public company costs such as listing fees, audit fees, compliance costs, and Board of Directors fees. Additionally, certain corporate executive management costs, including costs of the corporate executive leadership team and corporate management stock-based compensation expenses are not allocated to the operating segments. Finally, interest expense, income taxes, and certain other items included in other income and expense which are managed on a consolidated basis are not allocated to the operating segments. During the six months ended June 30, 2024, the Company sold a former joint venture facility located in Magnolia, Texas generating a $3,477 gain on sale recorded in “(Gain) on sale of former joint venture facility” which is included as a component of corporate operating income. The following table demonstrates a reconciliation of reportable segment net profit to the Company’s consolidated total for the periods presented: Three Months Ended Six Months Ended 2024 2023 2024 2023 (As Restated) Income from operations: Total segment operating income $ 9,124 $ 9,744 $ 14,514 $ 11,798 Gain on sale of former joint venture facility — — 3,477 — Interest expense - net (1,493) (1,574) (2,618) (2,962) Other income (expense) - net 84 (1,084) 337 (2,933) Public company costs (1,621) (1,217) (2,840) (1,873) Corporate executive management costs (1,885) (1,155) (3,292) (1,521) Corporate management stock-based compensation (880) (604) (1,479) (1,148) Other (166) (54) (242) (17) Income before income taxes $ 3,163 $ 4,056 $ 7,857 $ 1,344 Depreciation/Amortization: Total segment depreciation/amortization $ 3,018 $ 3,412 $ 6,151 $ 6,841 Corporate depreciation/amortization 467 447 925 888 Depreciation/amortization $ 3,485 $ 3,859 $ 7,076 $ 7,729 Expenditures for Long-Lived Assets: Total segment expenditures for long-lived assets $ 1,480 $ 708 $ 4,049 $ 1,066 Corporate expenditures for long-lived assets 574 88 717 429 Expenditures for long-lived assets $ 2,054 $ 796 $ 4,766 $ 1,495 The following table illustrates assets of the Company by reportable segment for the periods presented: June 30, December 31, Rail, Technologies, and Services $ 174,486 $ 156,638 Infrastructure Solutions 129,769 130,247 Unallocated corporate assets 29,006 25,516 Total $ 333,261 $ 312,401 On March 30, 2023, the Company sold substantially all the operating assets of its Chemtec Energy Services LLC (“Chemtec”) business for $5,344 in proceeds generating a $2,065 loss on sale, recorded in “Other (income) expense - net” for the six months ended June 30, 2023. The Chemtec business was reported in the Steel Products business unit in the Infrastructure segment. On June 30, 2023, the Company sold substantially all the operating assets of the prestressed concrete railroad tie business operated by its wholly-owned subsidiary, CXT Incorporated (“Ties”), located in Spokane, WA, for $2,362 in proceeds, generating a $1,009 loss on the sale, which was recorded in “Other expense (income) - net” for the three and six months ended June 30, 2023. The Ties business was reported in the Rail Products business unit within the Rail segment. On August 30, 2023, the Company announced the discontinuation of its Bridge Products grid deck product line (“Bridge Exit”) which was reported in the Steel Products business unit within the Infrastructure segment. The decision to exit the bridge grid deck product line was a result of a weak bridge grid deck market condition and outlook due to customer adoption of newer technologies replacing the grid deck solution. The Company continues to operate its bridge forms product line which is a newer technology and not subject to the same challenging market conditions. The Bedford, PA based operations supporting the discontinued bridge grid deck product line expect to complete any remaining customer obligations during 2024. For the three months ended June 30, 2024 and 2023, the discontinued product line had $1,157 and $1,975 in sales, respectively. For the six months ended June 30, 2024 and 2023, the discontinued product line had $1,967 and $3,466 in sales, respectively. During the six months ended June 30, 2024, the Company incurred an immaterial amount of exit costs, all of which were personnel expenses. The Company does not expect to incur additional material exit costs in the remainder of 2024. Cumulatively, the Company has incurred a total of $1,476 in exit costs for the Bridge Exit, which included $474 in inventory write-downs, $740 in personnel expenses, which were recorded in “Cost of goods sold,” and $262 in other exit costs, which were recorded in “Selling and administrative expenses,” the majority of which were incurred in the last six months of 2023. The majority of cash payments were made in early 2024. On November 17, 2023, the Company acquired the operating assets of Cougar Mountain Precast, LLC (“Cougar”), located in Caldwell, Idaho, which is a licensed manufacturer of Redi-Rock and natural concrete products for $1,644, subject to hold back payments, to be paid over the next twelve months or utilized to satisfy post-close working capital adjustments or indemnity claims. Cougar has been included in the Precast Concrete Products business unit within the Infrastructure segment.

The Company recognizes revenue at the point in time at which the customer obtains control of the product or service, which is generally when the product title passes to the customer upon shipment or the service has been rendered to the customer. In limited cases, title does not transfer and revenue is not recognized until the customer has received the products at a designated physical location. Net sales by the timing of the transfer of goods and services was as follows for the periods presented: Three Months Ended June 30, 2024 Rail, Technologies, and Services Infrastructure Solutions Total Point in time $ 69,923 $ 35,127 $ 105,050 Over time 15,671 20,075 35,746 Total net sales $ 85,594 $ 55,202 $ 140,796 Three Months Ended June 30, 2023 Rail, Technologies, and Services Infrastructure Solutions Total Point in time $ 75,923 $ 34,947 $ 110,870 Over time 15,693 21,471 37,164 Total net sales $ 91,616 $ 56,418 $ 148,034 Six Months Ended June 30, 2024 Rail, Technologies, and Services Infrastructure Solutions Total Point in time $ 135,462 $ 64,784 $ 200,246 Over time 32,755 32,115 64,870 Total net sales $ 168,217 $ 96,899 $ 265,116 Six Months Ended June 30, 2023 Rail, Technologies, and Services Infrastructure Solutions Total Point in time $ 129,757 $ 64,075 $ 193,832 Over time 26,243 43,447 69,690 Total net sales $ 156,000 $ 107,522 $ 263,522 The Company’s performance obligations under long-term agreements with its customers are generally satisfied over time. Over time revenue is primarily comprised of transit infrastructure and technology services and solutions projects within the Rail segment, precast concrete buildings within the Precast Concrete Products division in the Infrastructure segment, and long-term bridge projects and custom precision metering systems within the Steel Products division in the Infrastructure segment. Revenue under these long-term agreements is generally recognized over time, either using an input measure based upon the proportion of actual costs incurred to estimated total project costs or an input measure based upon actual labor costs as a percentage of estimated total labor costs, depending upon which measure the Company believes best depicts the Company’s performance to date under the terms of the contract, or an output method, specifically units delivered, based upon certain customer acceptance and delivery requirements. The use of an input or an output measure to recognize revenue is determined based on what is most appropriate given the nature of the work performed and terms of the associated agreement. Accounting for these long-term agreements involves the use of various techniques to estimate total revenues and costs. The Company estimates profit on these long-term agreements as the difference between total estimated revenues and expected costs to complete a contract and recognizes that profit over the life of the contract. As a result of management’s reviews of contract-related estimates the Company makes adjustments to contract estimates that impact our revenue and profit totals. Changes in estimates are primarily attributed to updated considerations, including economic conditions and historic contract patterns, resulting in changes to anticipated revenue from existing contracts. During the three and six months ended June 30, 2024, reductions to net sales stemming from changes in actual and expected values of certain commercial contracts and settlements of such contracts were $1,477. Such adjustments were $1,035 and $1,428 during the three and six months ended June 30, 2023, respectively. The Company’s estimates related to these long-term agreements are further described in Note 4 Revenue of the Notes to the Company’s Consolidated Financial Statements contained in its Annual Report on Form 10-K/A for the year ended December 31, 2023. Revenue recognized over time was as follows for the periods presented: Three Months Ended Percentage of Total Net Sales 2024 2023 2024 2023 Over time input method $ 14,096 $ 15,724 10.0 % 10.6 % Over time output method 21,650 21,440 15.4 14.5 Total over time sales $ 35,746 $ 37,164 25.4 % 25.1 % Six Months Ended Percentage of Total Net Sales 2024 2023 2024 2023 Over time input method $ 27,239 $ 31,935 10.3 % 12.1 % Over time output method 37,631 37,755 14.2 14.3 Total over time sales $ 64,870 $ 69,690 24.5 % 26.4 % The timing of revenue recognition, billings, and cash collections results in billed receivables, costs in excess of billings (included in “Contract assets - net”), and billings in excess of costs (contract liabilities), included in “Deferred revenue” within the Condensed Consolidated Balance Sheets. The following table sets forth the Company’s contract assets: Contract Assets Balance as of December 31, 2023 $ 29,489 Net additions to contract assets 6,223 Transfers from contract asset balance to accounts receivable (15,150) Balance as of June 30, 2024 $ 20,562 The following table sets forth the Company’s contract liabilities: Contract Liabilities Balance as of December 31, 2023 $ 2,189 Revenue recognized from contract liabilities (1,023) Increase in billings in excess of cost, excluding revenue recognized 388 Other adjustments (55) Balance as of June 30, 2024 $ 1,499 The Company has established policies regarding allowance for credit losses associated with contract assets, which includes standalone reserve assessments for its long term, complex contracts as needed as well as detailed regular review and updates to contract margins, progress, and value. A standard reserve threshold is applied to contract assets related to short term, less complex contracts. Management also regularly reviews collection patterns and future expected collections and makes necessary revisions to allowance for credit losses related to contract assets. As of June 30, 2024, the Company had approximately $249,805 of remaining performance obligations, which are also referred to as backlog. Approximately 10.2% of the June 30, 2024 backlog was related to projects that are anticipated to extend beyond June 30, 2025.

Purchase accounting finalization during the first quarter of 2024 included adjustments to record $429 of gross intangible assets for customer relationships with a weighted average amortization period of 5 years. The Company performs goodwill impairment tests annually during the fourth quarter, and also performs interim goodwill impairment tests if it is determined that it is more likely than not that the fair value of a reporting unit is less than the carrying amount. Qualitative factors are assessed to determine whether it is more likely than not that the fair value of a reporting unit is less than the carrying amount, which included the impacts of current economic conditions, including but not limited to labor markets, supply chains, and other inflationary costs. However, these factors can be unpredictable and are subject to change. No interim goodwill impairment test was required as a result of the evaluation of qualitative factors as of June 30, 2024. However, future impairment charges could result if future projections diverge unfavorably from current expectations.

The Credit Agreement, as amended, modifies the prior amended revolving credit facility, on terms more favorable to the Company and extends the maturity from April 30, 2024 to August 13, 2026. The Credit Agreement provides for a five-year, revolving credit facility that permits aggregate borrowings of the Borrowers up to $130,000 with a sublimit of the equivalent of $25,000 U.S. dollars that is available to the Canadian and United Kingdom borrowers in the aggregate. The Credit Agreement’s incremental loan feature permits the Company to increase the available commitments under the facility by up to an additional $50,000 subject to the Company’s receipt of increased commitments from existing or new lenders and the satisfaction of certain conditions. On August 12, 2022, the Company entered into a second amendment to its Credit Agreement (the “Second Amendment”) which added an additional tier to the pricing grid and provided for the conversion from LIBOR-based to SOFR-based borrowings. Borrowings under the Credit Agreement, as amended, will bear interest at rates based upon either the base rate or SOFR rate plus applicable margins. The Credit Agreement includes two financial covenants: (a) Maximum Gross Leverage Ratio, defined as the Company’s consolidated Indebtedness (as defined in the Credit Agreement) divided by the Company’s consolidated EBITDA, which must not exceed (i) 3.25 to 1.00 for all testing periods other than during an Acquisition Period (as defined in the Credit Agreement), and (ii) 3.50 to 1.00 for all testing periods occurring during an Acquisition Period, and (b) Minimum Consolidated Fixed Charge Coverage Ratio, defined as the Company’s consolidated EBITDA divided by the Company’s Fixed Charges (as defined in the Credit Agreement), which must be more than 1.05 to 1.00. As of June 30, 2024, the Company was in compliance with the covenants in the Credit Agreement, as amended, and had outstanding letters of credit of approximately $2,084.

For the six months ended June 30, 2024 and 2023, the Company recorded an income tax expense of $635 and $22, respectively, on pre-tax income of $7,857 and $1,344, respectively, for an effective income tax rate of 8.1% and 1.6%, respectively. The Company’s effective income tax rate for the three and six months ended June 30, 2024 differed from the federal statutory rate of 21% primarily due to the realization of a portion of its U.S. deferred tax assets previously offset by a valuation allowance. The Company continues to maintain a full valuation allowance against its U.S. deferred tax assets, which is likely to result in significant variability of the effective tax rate in the current year. Changes in pre-tax income projections, combined with the seasonal nature of our businesses, could also impact the effective income tax rate each quarter.

Fair Value Measurements	Jun. 30, 2024
Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company determines the fair value of assets and liabilities based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. The fair values are based on assumptions that market participants would use when pricing an asset or liability, including assumptions about risk and the risks inherent in valuation techniques and the inputs to valuations. The fair value hierarchy is based on whether the inputs to valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s own assumptions of what market participants would use. The fair value hierarchy includes three levels of inputs that may be used to measure fair value as described below. Level 1: Quoted market prices in active markets for identical assets or liabilities. Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data. Level 3: Unobservable inputs that are not corroborated by market data. The classification of a financial asset or liability within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. SOFR-based interest rate swaps - To reduce the impact of interest rate changes on outstanding variable-rate debt, the Company amended and entered into forward-starting SOFR-based interest rate swaps with notional values totaling $20,000 and $20,000 effective August 12, 2022 and August 31, 2022, respectively. The fair value of the interest rate swaps are based on market-observable forward interest rates and represents the estimated amount that the Company would pay to terminate the agreements. As such, the swap agreements are classified as Level 2 within the fair value hierarchy. As of June 30, 2024 and December 31, 2023, the interest rate swaps were recorded in “ Other current assets Fair Value Measurements at Reporting Date Fair Value Measurements at Reporting Date June 30, Level 1 Level 2 Level 3 December 31, Level 1 Level 2 Level 3 Interest rate swaps $ 1,146 $ — $ 1,146 $ — $ 1,225 $ — $ 1,225 $ — Total assets $ 1,146 $ — $ 1,146 $ — $ 1,225 $ — $ 1,225 $ — The $20,000 interest rate swap agreements that became effective August 2022 are accounted for as cash flow hedges and the objective of the hedges is to offset the expected interest variability on payments associated with the interest rate on our debt. The gains and losses related to the interest rate swaps are reclassified from “Accumulated other comprehensive loss” in our Condensed Consolidated Balance Sheets and included in “Interest expense - net” in our Condensed Consolidated Statements of Operations as the interest expense from our debt is recognized. For the three months ended June 30, 2024 and 2023, the Company recognized interest income of $340 and $295, respectively, from interest rate swaps. For the six months ended June 30, 2024 and 2023, the Company recognized interest income of $677 and $540 respectively, from interest rate swaps.

Employee-related Liabilities [Abstract]
Retirement Plans	Retirement Plans The Company has three retirement plans that cover its hourly and salaried employees in the United States: one defined benefit plan, which is frozen, and two defined contribution plans. Employees are eligible to participate in the appropriate plan based on employment classification. The Company’s contributions to the defined benefit and defined contribution plans are governed by the Employee Retirement Income Security Act of 1974, as amended (“ERISA”) and the Company’s policy and investment guidelines applicable to each respective plan. The Company’s policy is to contribute at least the minimum in accordance with the funding standards of ERISA. The Company maintains one defined contribution plan for its employees in Canada. In the United Kingdom, the Company maintains two defined contribution plans and a defined benefit plan, which is frozen. On May 23, 2024, the Company’s Board of Directors approved the termination of our frozen L.B. Foster Company Merged Retirement Plan (the “US DB Plan”) and the Portec Rail Products (UK) Limited Pension Scheme (the “UK DB Plan”). The transfer of plan assets and obligations to insurers, and subsequent termination is expected to be completed by June 30, 2025. The Company’s US DB Plan is underfunded as of June 30, 2024, and will require cash payments of approximately $2,000 to $3,000 to effectuate the termination. The estimated cash payments are subject to change due to changes in market conditions that can impact the return on plan assets that are held by the US DB Plan and the UK DB Plan. The UK DB Plan is fully funded as of June 30, 2024, and we do not expect any additional contributions to be required during the termination process. These plans are discussed in further detail below. United States Defined Benefit Plan Net periodic pension costs were as follows for the periods presented: Three Months Ended Six Months Ended 2024 2023 2024 2023 Interest cost $ 66 $ 71 $ 132 $ 143 Expected return on plan assets (68) (64) (136) (128) Recognized net actuarial loss 15 16 30 31 Net periodic pension cost $ 13 $ 23 $ 26 $ 46 The Company has made contributions to its United States defined benefit plan of $200 during the six months ended June 30, 2024 and expects to make total contributions of approximately $370 during 2024. United Kingdom Defined Benefit Plan Net periodic pension costs were as follows for the periods presented: Three Months Ended Six Months Ended 2024 2023 2024 2023 Interest cost $ 56 $ 56 $ 112 $ 112 Expected return on plan assets (93) (84) (186) (168) Amortization of prior service costs and transition amount 6 6 12 12 Recognized net actuarial loss 8 3 16 6 Net periodic pension income $ (23) $ (19) $ (46) $ (38) United Kingdom regulations require trustees to adopt a prudent approach to funding required contributions to defined benefit pension plans. For the six months ended June 30, 2024, the Company contributed approximately $156 to the plan. The Company anticipates total contributions of approximately $316 to the United Kingdom pension plan during 2024. Defined Contribution Plans The Company sponsors five defined contribution plans for hourly and salaried employees across its domestic and international facilities. The following table summarizes the expense associated with the contributions made to these plans for the periods presented: Three Months Ended Six Months Ended 2024 2023 2024 2023 United States $ 720 $ 793 $ 1,271 $ 1,407 Canada 34 32 110 94 United Kingdom 287 315 565 576 $ 1,041 $ 1,140 $ 1,946 $ 2,077

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	Commitments and Contingent Liabilities Product Liability Claims The Company is subject to product warranty claims that arise in the ordinary course of its business. For certain manufactured products, the Company maintains a product warranty accrual, which is adjusted on a monthly basis as a percentage of cost of sales. In addition, the product warranty accrual is adjusted periodically based on the identification or resolution of known individual product warranty claims. Union Pacific Railroad (“UPRR”) Concrete Tie Matter On March 13, 2019, the Company and its subsidiary, CXT Incorporated (“CXT”), entered into a Settlement Agreement (the “Settlement Agreement”) with UPRR to resolve the then-pending litigation in the matter of Union Pacific Railroad Company v. L.B. Foster Company and CXT Incorporated , Case No. CI 15-564, in the District Court for Douglas County, Nebraska. Under the Settlement Agreement, the Company and CXT will pay UPRR the aggregate amount of $50,000 without pre-judgment interest, which began with a $2,000 immediate payment, and with the remaining $48,000 paid in installments over a six-year period commencing on the effective date of the Settlement Agreement through December 2024 pursuant to a Promissory Note. Additionally, commencing in January 2019 and through December 2024, UPRR agreed to purchase and has been purchasing from the Company and its subsidiaries and affiliates, a cumulative total amount of $48,000 of products and services, targeting $8,000 of annual purchases per year beginning March 13, 2019, per letters of intent under the Settlement Agreement. During the third quarter of 2021, in connection with the Company’s divestiture of its Piling Products division, the targeted annual purchases per year have been reduced to $6,000 for 2021 through 2024. The Settlement Agreement also includes a mutual release of all claims and liability regarding or relating to all CXT pre-stressed concrete railroad ties with no admission of liability and dismissal of the litigation with prejudice. The expected payment under the UPRR Settlement Agreement for the remainder of the year ending December 31, 2024 is $6,000, upon which the obligation for the Settlement Agreement will be satisfied. Environmental and Legal Proceedings The Company is subject to national, state, foreign, provincial, and/or local laws and regulations relating to the protection of the environment. The Company’s efforts to comply with environmental regulations may have an adverse effect on its future earnings. On June 5, 2017, a General Notice Letter was received from the United States Environmental Protection Agency (“EPA”) indicating that the Company may be a potentially responsible party (“PRP”) regarding the Portland Harbor Superfund Site cleanup along with numerous other companies. More than 140 other companies received such a notice. The Company and a predecessor owned and operated a facility near the harbor site for a period prior to 1982. The net present value and undiscounted costs of the selected remedy throughout the harbor site are estimated by the EPA to be approximately $1.1 billion and $1.7 billion, respectively, and the remedial work is expected to take as long as 13 years to complete. These costs may increase given that the remedy will not be initiated or completed for several years. The Company is reviewing the basis for its identification by the EPA and the nature of the historic operations of a Company predecessor near the site. Additionally, the Company executed a PRP agreement which provides for a private allocation process among almost 100 PRPs in a working group whose work is ongoing and involves a process that will ultimately conclude a proposed allocation of liability for cleanup of the site and various sub-areas. The Company does not have any individual risk sharing agreements in place with respect to the site, and was only associated with the site from 1976 to when it purchased the stock of a company whose assets it sold in 1982 and which was dissolved in 1994. On March 26, 2020, the EPA issued a Unilateral Administrative Order to two parties requiring them to perform remedial design work for that portion of the Harbor Superfund Site that includes the area closest to the facility; the Company was not a recipient of this Unilateral Administrative Order. The Company cannot predict the ultimate impact of these proceedings because of the large number of PRPs involved throughout the harbor site, the size and extent of the site, the degree of contamination of various wastes, varying environmental impacts throughout the harbor site, the scarcity of data related to the facility once operated by the Company and a predecessor, potential comparative liability between the allocation parties and regarding non-participants, and the speculative nature of the remediation costs. Based upon information currently available, management does not believe that the Company’s alleged PRP status regarding the Portland Harbor Superfund Site or other compliance with the present environmental protection laws will have a material adverse effect on the financial condition, results of operations, cash flows, competitive position, or capital expenditures of the Company. As more information develops and the allocation process is completed, and given the resolution of factors like those described above, an unfavorable resolution could have a material adverse effect. As of June 30, 2024 and December 31, 2023, the Company maintained environmental reserves approximating $2,398 and $2,417, respectively. The Company is also subject to other legal proceedings and claims that arise in the ordinary course of its business. Legal actions are subject to inherent uncertainties, and future events could change management’s assessment of the probability or estimated amount of potential losses from pending or threatened legal actions. Based on available information, it is the opinion of management that the ultimate resolution of pending or threatened legal actions, both individually and in the aggregate, will not result in losses having a material adverse effect on the Company’s financial position or liquidity as of June 30, 2024. If management believes that, based on available information, it is at least reasonably possible that a material loss (or additional material loss in excess of any accrual) will be incurred in connection with any legal actions, the Company discloses an estimate of the possible loss or range of loss, either individually or in the aggregate, as appropriate, if such an estimate can be made, or discloses that an estimate cannot be made. Based on the Company’s assessment as of June 30, 2024, no such disclosures were considered necessary.

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events On August 5, 2024, the Board of Directors approved the modification of the Company’s stock repurchase program. The modifications include revising the repurchase program expiration date from February 2026 to February 2025. Additionally, the Board of Directors removed the restriction which previously limited repurchases to $5,000 in any trailing 12-month period. The authorized repurchase amount was unchanged at $15,000. As of June 30, 2024, the Company has repurchased stock of $4,021, with $10,979 of the original $15,000 authorized remaining. Any repurchases will continue to be subject to the Company’s liquidity, including availability of borrowings and covenant compliance under its revolving credit facility, and other capital needs of the business. In August 2024, the Company announced an enterprise restructuring program aligned with its strategy to reduce costs and enable investment in growth platforms. Total restructuring program includes both headcount reductions and attrition and is expected to result in severance and outplacement services charges totaling approximately $1,500. The majority of the restructuring costs will be recorded in the third quarter of 2024 with any remaining costs being recorded in the fourth quarter of 2024. Annual run rate savings are expected to be approximately $4,500 with approximately $2,000 in savings being realized in 2024.

Basis of Presentation	The accompanying Unaudited Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. The year-end consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP. In the opinion of management, all estimates and adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three and six months ended June 30, 2024 are not necessarily indicative of the results that may be expected for the year ending December 31, 2024. This Quarterly Report on Form 10-Q/A should be read in conjunction with the consolidated financial statements and footnotes thereto included in L.B. Foster Company’s Annual Report on Form 10-K/A for the year ended December 31, 2023. In this Quarterly Report on Form 10-Q/A, references to “we,” “us,” “our,” and the “Company” refer collectively to L.B. Foster Company and its consolidated subsidiaries.
Recently Issued Accounting Standards	In November 2023, the FASB issued Accounting Standards Update 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” (“ASU 2023-07”), which requires enhanced disclosures regarding significant segment expenses that are regularly reviewed by the chief operating decision maker (“CODM”) and included in each reported measure of segment profit or loss, including an amount for “other segment items” by reportable segment and a description of its composition. ASU 2023-07 also requires entities to disclose the title and position of the CODM and an explanation of how the CODM uses reported measures of segment profit or loss to assess performance and allocate resources. The amendments are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024 with early adoption permitted. The Company expects ASU 2023-07 to only impact its disclosures with no impacts to its consolidated financial condition, results of operations, and cash flows. In December 2023, the FASB issued Accounting Standards Update 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”). ASU 2023-09 requires entities to disclose additional information with respect to the effective tax rate reconciliation and disaggregation of income tax expense and income taxes paid by jurisdiction. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the impact of ASU 2023-09, but expects this ASU to only impact its disclosures with no impacts to its consolidated financial condition, results of operations, and cash flows.
