NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

(Dollars in thousands, except share data)

Note 1. 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 months ended March 31, 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 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 for the year ended December 31, 2023. In this Quarterly Report on Form 10-Q, references to “we,” “us,” “our,” and the “Company” refer collectively to L.B. Foster Company and its consolidated subsidiaries.

Note 2. 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, 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 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 Solutions 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 March 31, 2024				Three Months Ended March 31, 2023
	Net Sales		Segment Operating Profit (Loss)		Net Sales		Segment Operating Profit (Loss)
Rail, Technologies, and Services	$	82,623	$	6,778	$	64,384	$	2,388
Infrastructure Solutions	41,697		(1,393)		51,104		(356)
Total	$	124,320	$	5,385	$	115,488	$	2,032

Segment profit (loss) from operations, as shown above, includes allocated corporate operating expenses. Operating expenses related to corporate headquarter functions that directly support the segment activity are allocated 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. The expense allocation excludes certain corporate costs that are separately managed from the segments.

The following table demonstrates a reconciliation of reportable segment net profit to the Company’s consolidated total for the periods presented:

8

	Three Months Ended March 31,
	2024		2023
Operating profit for reportable segments	$	5,385	$	2,032
Interest expense - net	(1,125)		(1,388)
Other income (expense) - net	3,536		(1,827)
Unallocated corporate expenses and other unallocated charges	(3,102)		(1,529)
Income (loss) before income taxes	$	4,694	$	(2,712)

The following table illustrates assets of the Company by reportable segment for the periods presented:

	March 31, 2024		December 31, 2023
Rail, Technologies, and Services	$	167,565	$	157,023
Infrastructure Solutions	129,852		130,667
Unallocated corporate assets	28,984		25,516
Total	$	326,401	$	313,206

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 three months ended March 31, 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 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 Bedford, PA based operations supporting the product line expects to complete any remaining customer obligations during 2024. For the three months ended March 31, 2024 and 2023, the product line had $810 and $1,491 in sales, respectively. During the three months ended March 31, 2024, the Company incurred $73 of exit costs recorded in “Other (income) expense - net,” all of which were personnel expenses. The Company expects to incur an additional $111 of personnel expenses associated with the exit through 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, and $262 in other exit costs.

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.

Note 3. Revenue

The following table summarizes the Company’s sales by major product and service line for the periods presented:

	Three Months Ended March 31,
	2024		2023
Rail Products	$	53,038	$	40,228
Global Friction Management	14,022		15,820
Technology Services and Solutions	15,563		8,336
Rail, Technologies, and Services	82,623		64,384
Precast Concrete Products	21,091		24,288
Steel Products	20,606		26,816
Infrastructure Solutions	41,697		51,104
Total net sales	$	124,320	$	115,488

The majority of the Company’s revenue is from products transferred and services rendered to customers at a point in time. 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 March 31, 2024
	Rail, Technologies, and Services		Infrastructure Solutions		Total
Point in time	$	65,539	$	29,657	$	95,196
Over time	17,084		12,040		29,124
Total net sales	$	82,623	$	41,697	$	124,320
	Three Months Ended March 31, 2023
	Rail, Technologies, and Services		Infrastructure Solutions		Total
Point in time	$	53,834	$	29,128	$	82,962
Over time	10,550		21,976		32,526
Total net sales	$	64,384	$	51,104	$	115,488

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 months ended March 31, 2024, reductions to net sales stemming from changes in actual and expected values of certain commercial contracts and settlements of such contracts were immaterial. Such adjustments were $393 during the three months ended March 31, 2023. 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 for the year ended December 31, 2023.

Revenue recognized over time was as follows for the periods presented:

	Three Months Ended March 31,				Percentage of Total Net Sales Three Months Ended March 31,
	2024		2023		2024		2023
Over time input method	$	13,143	$	16,211	10.6	%	14.0	%
Over time output method	15,981		16,315		12.9		14.1
Total over time sales	$	29,124	$	32,526	23.4	%	28.2	%

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

Net additions to contract assets	4,212
Transfers from contract asset balance to accounts receivable	(9,560)
Balance as of March 31, 2024	$	24,141

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 March 31, 2024, the Company had approximately $222,261 of remaining performance obligations, which is also referred to as backlog. Approximately 10.5% of the March 31, 2024 backlog was related to projects that are anticipated to extend beyond March 31, 2025.

Note 4. Goodwill and Other Intangible Assets

The following table presents the changes in goodwill balance by reportable segment for the period presented:

	Rail, Technologies, and Services		Infrastructure Solutions		Total
Balance as of December 31, 2023	$	20,466	$	12,121	$	32,587
Cougar purchase accounting adjustment	—		(445)		(445)
Foreign currency translation impact	(147)		—		(147)
Balance as of March 31, 2024	$	20,319	$	11,676	$	31,995

On November 17, 2023, the Company acquired Cougar Mountain Precast, LLC., for which all purchase accounting adjustments were finalized as of March 31, 2024. Purchase accounting finalization during the three months ended March 31, 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

11

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 March 31, 2024. However, future impairment charges could result if future projections diverge unfavorably from current expectations.

The following table sets forth the components of the Company’s intangible assets for the periods presented:

	March 31, 2024
	Weighted Average Amortization Period In Years	Gross Carrying Value		Accumulated Amortization		Net Carrying Amount

The Company established the allowance for credit losses by calculating the amount to reserve based on the age of a given trade receivable and considering historical collection patterns, bad debt expense experience, expected future trends of collections, current and expected market conditions, and any other relevant subjective adjustments as needed. Management maintains high-quality credit review practices and positive customer relationships that mitigate credit risks. The Company’s reserves are regularly reviewed and revised as necessary.

The following table sets forth the Company’s allowance for credit losses:

On August 13, 2021, the Company, its domestic subsidiaries, and certain of its Canadian and United Kingdom subsidiaries (collectively, the “Borrowers”), entered into the Fourth Amended and Restated Credit Agreement (the “Credit Agreement”) with PNC Bank, N.A., Citizens Bank, N.A., Wells Fargo Bank, National Association, Bank of America, N.A., and BMO Harris Bank, National Association. 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 March 31, 2024, the Company was in compliance with the covenants in the Credit Agreement, as amended, and had outstanding letters of credit of approximately $2,432.

Note 8. Earnings Per Common Share

(Share amounts in thousands)

The following table sets forth the computation of basic and diluted earnings (loss) per common share for the periods indicated:

	Three Months Ended March 31,
	2024		2023
Numerator for basic and diluted earnings (loss) per common share:
Net income (loss) attributable to L.B. Foster Company	$	4,436	$	(2,152)
Denominator:
Weighted average shares outstanding	10,762		10,792
Denominator for basic earnings (loss) per common share	10,762		10,792
Effect of dilutive securities:
Stock compensation plans	223		—
Dilutive potential common shares	223		—
Denominator for diluted earnings (loss) per common share - adjusted weighted average shares outstanding	10,985		10,792
Basic earnings (loss) per common share	$	0.41	$	(0.20)
Diluted earnings (loss) per common share	$	0.40	$	(0.20)

There were 0 and 101 anti-dilutive shares for the three months ended March 31, 2024 and March 31, 2023, respectively.

Note 9. Income Taxes

For the three months ended March 31, 2024 and 2023, the Company recorded an income tax expense of $289 on pre-tax income of $4,694 and an income tax benefit of $541 on pre-tax losses of $2,712, respectively, for an effective income tax rate of 6.2% and 19.9%, respectively. The Company's effective income tax rate for the three months ended March 31, 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.

Note 10. Stock-Based Compensation

The Company recorded stock-based compensation expense of $1,033 and $884 for the three months ended March 31, 2024 and 2023, respectively. As of March 31, 2024, unrecognized compensation expense for awards that the Company expects to vest approximated $4,711. The Company will recognize this unrecognized compensation expense over the upcoming 1.9 years through March 1, 2026.

As of March 31, 2024, the Company had stock awards issued pursuant to the 2022 Equity and Incentive Compensation Plan (the "Equity and Incentive Plan") and its predecessor, the 2006 Omnibus Incentive Compensation Plan (the "Omnibus Plan"). No stock options are outstanding under either the Omnibus Plan or Equity and Incentive Plan and, as such, there was no stock-based compensation expense related to stock options recorded for the March 31, 2024 and 2023.

Non-Employee Director Fully-Vested and Restricted Stock Awards

Since May 2018, non-employee directors have been awarded shares of the Company’s common stock on each date the non-employee directors were elected at the annual shareholders’ meeting to serve as directors, subject to a one-year vesting requirement. The Deferred Compensation Plan for Non-Employee Directors under the Omnibus Plan and, by amendment, under the Equity and Incentive Compensation Plan, which permits non-employee directors of the Company to defer receipt of earned cash and/or stock compensation for service on the Board into deferred stock units.

Restricted Stock and Performance-Based Stock and Share Units

Under the Equity and Incentive Compensation Plan and Omnibus Plan, the Company grants certain employees restricted stock and performance-based stock and share units. The forfeitable restricted stock awards granted generally time-vest ratably over a three-year period, unless indicated otherwise by the underlying restricted stock award agreement. Performance unit awards are offered annually under separate three-year long-term incentive programs, unless indicated otherwise by the underlying performance unit award agreement. Performance units are subject to forfeiture and will be converted into common stock based upon the Company’s performance relative to performance measures and conversion multiples as defined in the underlying program.

14

The following table summarizes the restricted stock, deferred stock units, and performance-based stock and share unit activity for the periods presented:

	Restricted Stock	Deferred Stock Units	Performance-Based Stock and Share Units	Weighted Average Grant Date Fair Value
Outstanding as of December 31, 2023	264,970	12,404	560,338	$	14.10
Granted	13,064	—	—	23.03
Vested	(103,286)	—	(19,782)	13.92
Adjustment for incentive awards expected to vest	—	—	110	11.63

Outstanding as of March 31, 2024	173,748	12,404	540,229	$	13.81

Note 11. 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 March 31, 2024 and December 31, 2023, the interest rate swaps were recorded in “Other current assets” when the interest rate swaps’ fair market value are in an asset position, and “Other accrued liabilities” when in a liability position within our Condensed Consolidated Balance Sheets.

	Fair Value Measurements at Reporting Date								Fair Value Measurements at Reporting Date
	March 31, 2024		Level 1		Level 2		Level 3		December 31, 2023		Level 1		Level 2		Level 3
Interest rate swaps	$	1,331	$	—	$	1,331	$	—	$	1,225	$	—	$	1,225	$	—
Total assets	$	1,331	$	—	$	1,331	$	—	$	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 March 31, 2024 and 2023, the Company recognized interest income of $337 and $245, respectively, from interest rate swaps.

Note 12. 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

15

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. These plans are discussed in further detail below.

United States	$	551	$	614
Canada	76		62
United Kingdom	281		261
	$	908	$	937

Note 13. 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 $8,000, 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 March 31, 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 March 31, 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 March 31, 2024, no such disclosures were considered necessary.

(Dollars in thousands, except share data)

Forward-Looking Statements

This Quarterly Report on Form 10-Q contains “forward-looking” statements within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended, and Section 27A of the Securities Act of 1933, as amended. Many of the forward-looking statements provide management's current expectations of future events based on certain assumptions and include any statement that does not directly relate to any historical or current fact. Sentences containing words such as “believe,” “intend,” “plan,” “may,” “expect,” “should,” “could,” “anticipate,” “estimate,” “predict,” “project,” or their negatives, or other similar expressions of a future or forward-looking nature generally should be considered forward-looking statements. Forward-looking statements in this Quarterly Report on form 10-Q are based on management's current expectations and assumptions about future events that involve inherent risks and uncertainties and may concern, among other things, the Company’s expectations relating to our strategy, goals, projections, and plans regarding our financial position, liquidity, capital resources, and results of operations and decisions regarding our strategic growth initiatives, market position, and product development. While the Company considers these expectations and assumptions to be reasonable, they are inherently subject to significant business, economic, competitive, regulatory, and other risks and uncertainties, most of which are difficult to predict and many of which are beyond the Company’s control. The Company cautions readers that various factors could cause the actual results of the Company to differ materially from those indicated by forward-looking statements. Accordingly, investors should not place undue reliance on forward-looking statements as a prediction of actual results. Among the factors that could cause the actual results to differ materially from those indicated in the forward-looking statements are risks and uncertainties related to: any future global health crises, and the related social, regulatory, and economic impacts and the response thereto by the Company, our employees, our customers, and national, state, or local governments; a continuation or worsening of the adverse economic conditions in the markets we serve, including recession, the continued volatility in the prices for oil and gas, governmental travel restrictions, project delays, and budget shortfalls, or otherwise; volatility in the global capital markets, including interest rate fluctuations, which could adversely affect our ability to access the capital markets on terms that are favorable to us; restrictions on our ability to draw on our credit agreement, including as a result of any future inability to comply with restrictive covenants contained therein; a decrease in freight or transit rail traffic; environmental matters, including any costs associated with any remediation and monitoring of such matters; the risk of doing business in international markets, including compliance with anti-corruption and bribery laws, foreign currency fluctuations and inflation, global shipping disruptions, and trade restrictions or embargoes; our ability to effectuate our strategy, including cost reduction initiatives, and our ability to effectively integrate acquired businesses or to divest businesses, such as the recent dispositions of the Track Components, Chemtec, and Ties businesses, and acquisitions of the Skratch Enterprises Ltd., Intelligent Video Ltd., VanHooseCo Precast LLC, and Cougar Mountain Precast, LLC businesses and to realize anticipated benefits; costs of and impacts associated with shareholder activism; the timeliness and availability of materials from our major suppliers, as well as the impact on our access to supplies of customer preferences as to the origin of such supplies, such as customers’ concerns about conflict minerals; labor disputes; cybersecurity risks such as data security breaches, malware, ransomware, “hacking,” and identity theft, which could disrupt our business and may result in misuse or misappropriation of confidential or proprietary information, and could result in the disruption or damage to our systems, increased costs and losses, or an adverse effect to our reputation, business or financial condition; the continuing effectiveness of our ongoing implementation of an enterprise resource planning system; changes in current accounting estimates and their ultimate outcomes; the adequacy of internal and external sources of funds to meet financing needs, including our ability to negotiate any additional necessary amendments to our credit agreement or the terms of any new credit agreement, and reforms regarding the use of SOFR as a benchmark for establishing applicable interest rates; the Company’s ability to manage its working capital requirements and indebtedness; domestic and international taxes, including estimates that may impact taxes; domestic and foreign government regulations, including tariffs; economic conditions and regulatory changes caused by the United Kingdom’s exit from the European Union; geopolitical conditions, including the ongoing conflicts between Russia and Ukraine and Israel and Hamas; a lack of state or federal funding for new infrastructure projects; an increase in manufacturing or material costs; the loss of future revenues from current customers; and risks inherent in litigation and the outcome of litigation and product warranty claims. Should one or more of these risks or uncertainties materialize, or should the assumptions underlying the forward-looking statements prove incorrect, actual outcomes could vary materially from those indicated. Significant risks and uncertainties that may affect the operations, performance, and results of the Company’s business and forward-looking statements include, but are not limited to, those set forth under Item 1A, “Risk Factors,” and elsewhere in our Annual Report on Form 10-K for the year ended December 31, 2023, or as updated and/or amended by our other current or periodic filings with the Securities and Exchange Commission.

The forward-looking statements in this report are made as of the date of this report and we assume no obligation to update or revise any forward-looking statement, whether as a result of new information, future developments, or otherwise, except as required by the federal securities laws.

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 Bedford, PA based operations supporting the product line expects to complete any remaining customer obligations during 2024. For the three months ended March 31, 2024 and 2023, the product line had $810 and $1,491 in sales, respectively.

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.

Results Summary

Net sales of $124,320 for the three months ended March 31, 2024, increased by $8,832, or 7.6%, over the prior year quarter. The increase in sales is due to organic sales growth of $19,474 or 16.9%, partially offset by the divestiture of the Ties and Chemtec businesses as well as the Bridge Exit which reduced sales by $10,642 or 9.2%.

Gross profit for the three months ended March 31, 2024 increased $2,958 or 12.7%, over the prior year quarter and gross profit margins expanded by 90 basis points to 21.1%. The improvement in gross profit is due primarily to the portfolio changes that are a part of the Company’s strategic transformation, as well as uplift from increased sales volumes and product mix.

Selling and administrative expenses for the three months ended March 31, 2024 increased by $1,326, or 6.2%, over the prior year quarter, due primarily to increased personnel costs and professional services expenditures. Selling and administrative expenses as a percent of net sales decreased to 18.3% from 18.5% in the prior year quarter.

Net interest expense decreased $263 due to lower outstanding debt, on average, for the three months ended March 31, 2024 compared to the prior year quarter. The Company's outstanding debt balance was $78,085 as of March 31, 2024, compared to $80,096 as of March 31, 2023.

Other income for the three months ended March 31, 2024 was $3,536 and was primarily attributable to a gain of $3,477 on the sale of the Company’s former joint venture facility and land in Magnolia, Texas. Other expense - net for the three months ended March 31, 2023 was $1,827 and was primarily due to the $2,033 loss on the sale of Chemtec during the prior year quarter.

The Company’s effective income tax rate for the three months ended March 31, 2024 was 6.2%, compared to 19.9% in the prior year quarter. The Company’s effective income tax rate for the three months ended March 31, 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.

Net income attributable to the Company for the three months ended March 31, 2024 was $4,436, or $0.40 per diluted share, compared to a net loss in the prior year quarter of $2,152, or $0.20 per diluted share. Net income for the three months ended March 31, 2024 was

20

primarily driven by increased sales volumes, gross profit expansion and the gain on the sale of the Company’s former joint venture facility and land in Magnolia, Texas, partially offset by an increase in selling and administrative expenses.

Results of Operations - Segment Analysis

Rail, Technologies, and Services

	Three Months Ended March 31,						Change			Percent Change
	2024			2023			2024 vs. 2023			2024 vs. 2023
Net sales	$	82,623		$	64,384		$	18,239		28.3	%

Segment operating profit margin	8.2		%	3.7		%	450		bps	121.2

The Rail segment sales for the three months ended March 31, 2024 increased by $18,239, or 28.3%, compared to the prior year quarter. The increase was due to higher organic sales of $18,940 or 29.4%, partially offset by a $701 or 1.1% decrease from the divestiture of Ties. Rail Products sales increased $12,810 driven by strength in domestic markets served. Technology Services and Solutions sales increased by $7,227 due to strength in domestic rail safety markets served, as well as improvement in United Kingdom markets. Global Friction management sales declined $1,798 driven by the timing of orders which have increased from the 2023 fourth quarter by 29.6%.

The Rail segment gross profit increased by $4,287, or 30.0% compared to the prior year quarter, and gross profit margins expanded 30 basis points to 22.5%. Technology Services and Solutions business unit gross profit improved by $4,086 due to higher volume and improved mix. Higher volumes in Rail Products resulted in gross profit increasing by $1,369. Lower volumes and unfavorable product mix in the Global Friction Management business result in a decline in gross profit of $1,168.

Segment operating profit increased $4,390 compared to the prior year, and operating profit margins expanded 450 basis points to 8.2%. The increase was driven by improvement in gross profit levels as a result of increased sales volume and favorable business mix, particularly in the Technology Services and Solutions business unit.

During the current quarter, new orders within the Rail segment increased by $10,019, or 13.6%, compared to the prior year quarter. The increase in new orders was attributable to the Rail Products and Global Friction Management businesses, which was offset in part by the Ties divestiture which reduced orders by $2,729 as well as lower overall order rates in the Technology Services and Solutions business unit. Segment backlog as of March 31, 2024 was $86,038, a decrease of $27,555, or 24.3%, versus the prior year quarter. The decrease is attributed to the Rail Products business, including a reduction of $3,549 related to the divestiture of Ties, partially offset by a 27.7% increase in Global Friction Management backlog.

Infrastructure Solutions

	Three Months Ended March 31,						Change			Percent Change
	2024			2023			2024 vs. 2023			2024 vs. 2023
Net sales	$	41,697		$	51,104		$	(9,407)		(18.4)	%
Gross profit	$	7,678		$	9,007		$	(1,329)		(14.8)
Gross profit margin	18.4		%	17.6		%	80		bps	4.5
Segment operating loss	$	(1,393)		$	(356)		$	(1,037)		(291.3)
Segment operating loss margin	(3.3)		%	(0.7)		%	(260)		bps	(373.2)

The Infrastructure segment sales for the three months ended March 31, 2024 decreased by $9,407, or 18.4%, compared to the prior year quarter. The decrease in sales for the first quarter of 2024 was attributable to the divestiture of Chemtec and the Bridge Exit, which decreased sales by $9,260 and $681, respectively. Organic sales increased by $534, or 1.0%, while being adversely affected by weather conditions that impacted customer project execution in our Precast Concrete Products business.

The Infrastructure segment gross profit for the three months ended March 31, 2024, decreased by $1,329, or 14.8%, due primarily to the divestiture of Chemtec which reduced gross profit by $888 and softness in margins in our Precast Concrete Products business. Gross profit margins of 18.4% increased by 80 basis points over the prior year, driven by the favorable impact of portfolio changes.

21

Segment operating loss for the first quarter of 2024 was $1,393 compared to an operating loss in the prior year of $356. The segment operating loss was due to lower gross profit levels, which was partially offset by a decrease in amortization expense and selling and administrative expenses.

During the quarter, the Infrastructure segment had a decrease in new orders of $17,149, or 26.1%, compared to the prior year quarter. The decrease is due to an $8,538 impact associated with the divestiture of Chemtec and the Bridge Exit as well as decreases in orders in the Precast Concrete Products and Protective Coatings businesses. Backlog as of March 31, 2024 was $136,223, a decrease of $10,065, or 6.9%, versus the prior year quarter, driven primarily by a reduction of $8,509 related to the Bridge Exit.

Corporate

	Three Months Ended March 31,				Change		Percent Change
	2024		2023		2024 vs. 2023		2024 vs. 2023
Corporate expense and other unallocated charges	$	3,102	$	1,529	$	1,573	102.9	%

Unallocated corporate expenses increased in 2024 compared with 2023 primarily due to personnel costs and professional services expenditures.

Liquidity and Capital Resources

The Company’s principal sources of liquidity are its existing cash and cash equivalents, cash generated by operations, and the available capacity under the revolving credit facility, which provides for a total commitment of up to $130,000, of which $50,071 was available for borrowing as of March 31, 2024, subject to covenant restrictions. The Company’s primary needs for liquidity relate to working capital requirements for operations, capital expenditures, debt service obligations, payments related to the Union Pacific Railroad Settlement, tax obligations, outstanding purchase obligations, acquisitions and to support the share repurchase program. The Company’s total debt, including finance leases, was $78,085 and $55,273 as of March 31, 2024 and December 31, 2023, respectively, and was primarily comprised of borrowings under its revolving credit facility.

The following table reflects available funding capacity as of March 31, 2024:

	March 31, 2024
Cash and cash equivalents		$	3,148
Credit agreement:
Total availability under the credit agreement	130,000
Outstanding borrowings on revolving credit facility	(77,497)
Letters of credit outstanding	(2,432)
Net availability under the revolving credit facility		50,071
Total available funding capacity		$	53,219

As of March 31, 2024 we were in compliance with all covenants of the Credit Agreement and have $53,219 available funding capacity.

The Company’s operating cash flows are impacted from period to period by fluctuations in working capital needs, as well as its overall profitability. While the Company places an emphasis on working capital management in its operations, factors such as its contract mix, commercial terms, days sales outstanding (“DSO”), and market conditions as well as seasonality may impact its working capital. The Company regularly assesses its receivables and contract assets for collectability and realization, and provides allowances for credit losses where appropriate. The Company believes that its reserves for credit losses are appropriate as of March 31, 2024, but adverse changes in the economic environment and adverse financial conditions of its customers may impact certain of its customers’ ability to access capital and pay the Company for its products and services, as well as impact demand for its products and services.

The changes in cash and cash equivalents for the three months ended March 31, 2024 and 2023 were as follows:

	Three Months Ended March 31,
	2024		2023
Net cash (used in) provided by operating activities	$	(21,864)	$	6,932
Net cash provided by investing activities	1,209		4,661
Net cash provided by (used in) financing activities	21,298		(12,022)
Effect of exchange rate changes on cash and cash equivalents	(55)		186
Net increase (decrease) in cash and cash equivalents	$	588	$	(243)

Cash Flow from Operating Activities

During the three months ended March 31, 2024, net cash used in operating activities was $21,864, compared to cash provided operating activities of $6,932 during the prior year quarter. For the three months ended March 31, 2024, net income and adjustments to reconcile net income from operating activities provided $5,414, compared to $3,352 in the prior year quarter. Working capital and other assets and liabilities were a use of $27,278 in the current period, compared to a source of $3,580 in the prior year quarter. The change in operating cash flow for the three months ended March 31, 2024 versus the three months ended March 31, 2023 was largely driven by accounts receivable, which was a use of $4,042 during the current quarter compared to the $26,239 provided in the prior year quarter. Order execution and collection timing can impact accounts receivables in any given quarter.

Cash Flow from Investing Activities

Capital expenditures for the three months ended March 31, 2024 and 2023 were $2,292 and $699, respectively. Capital expenditures in both periods primarily relate to general plant and operational improvements throughout the Company, as well as organic growth initiatives. During the three months ended March 31, 2024, the Company divested the facility and land of its former joint venture in Magnolia, Texas generating a cash inflow of $3,501. During the three months ended March 31, 2023 the Company received cash proceeds from the Chemtec divestiture totaling $5,344.

Cash Flow from Financing Activities

During the three months ended March 31, 2024 the Company had an increase in outstanding debt of $22,911 compared to March 31, 2023 in which the Company has a decrease in debt of $12,047. The increase in debt for the three months ended March 31, 2024 was primarily due to cash used in operating activities due to organic growth initiatives and higher seasonal working capital needs. The decrease in debt for the 2023 period was due to lower working capital as well as proceeds received from the Chemtec divestiture during the quarter.

During the first quarter of 2023, the Company’s Board of Directors authorized the repurchase of up to $15,000 of the Company’s common stock in open market transactions through February 2026. For the three months ended March 31, 2024 the Company repurchased 16,555 shares of its stock for $385 under this program. Repurchases of shares of the Company’s common stock may be made from time to time in the open market or in such other manner as determined by the Company. The timing of the repurchases and the actual amount repurchased will depend on a variety of factors, including the market price of the Company’s shares, general market and economic conditions, and other factors. The stock repurchase program does not obligate the Company to acquire any particular amount of common stock and may be suspended or discontinued at any time.

Financial Condition

As of March 31, 2024, the Company had $3,148 in cash and cash equivalents and $50,071 of availability under its revolving credit facility, subject to covenant restrictions. As of March 31, 2024, approximately $2,729 of the Company’s cash and cash equivalents were held in non-domestic bank accounts.

The Company’s principal uses of cash in recent years have been to fund its operations, including capital expenditures, repurchase of shares, acquisitions, funding the UPRR Settlement Agreement, and service indebtedness. The Company views its short and long-term liquidity as being dependent on its results of operations, changes in working capital needs, and its borrowing capacity.

On August 13, 2021, the Company, its domestic subsidiaries, and certain of its Canadian and United Kingdom subsidiaries (collectively, the “Borrowers”), entered into the Fourth Amended and Restated Credit Agreement (the “Credit Agreement”) with PNC Bank, N.A., Citizens Bank, N.A., Wells Fargo Bank, National Association, Bank of America, N.A., and BMO Harris Bank, National Association. 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

23

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. For a discussion of the terms and availability of the credit facilities, please refer to Note 7 of the Notes to Condensed Consolidated Financial Statements contained in this Quarterly Report on Form 10-Q.

To reduce the impact of interest rate changes on outstanding variable-rate debt, the Company amended and entered into SOFR-based interest rate swaps with notional values totaling $20,000 and $20,000, effective August 12, 2022 and August 31, 2022, respectively, at which point the agreements effectively converted a portion of the debt from variable to fixed-rate borrowings during the term of the swap contract.

Backlog

Although backlog is not necessarily indicative of future operating results, the following table provides the backlog by segment:

	Backlog
	March 31, 2024		December 31, 2023		March 31, 2023
Rail, Technologies, and Services	$	86,038	$	84,418	$	113,593
Infrastructure Solutions	136,223		129,362		146,288
Total backlog	$	222,261	$	213,780	$	259,881

While a considerable portion of the Company’s business is backlog driven, certain businesses, including the Global Friction Management business unit, are not driven by backlog and therefore have insignificant levels of backlog throughout the year. Backlog decreased $37,620 compared to the prior year quarter due to $12,058 from businesses that were divested and a discontinued product line. The remaining decline is associated with the timing of large orders for the Rail Products business.

Critical Accounting Estimates

The Condensed Consolidated Financial Statements have been prepared in conformity with US GAAP. The preparation of the Condensed Consolidated Financial Statements requires management to make estimates and judgments that affect the reported amount of assets, liabilities, revenues, and expenses, and the related disclosure of contingent assets and liabilities. As a result, actual results could differ from these estimates. The Company has concluded that there have been no significant changes to its critical accounting policies or estimates as described in its Annual Report on Form 10-K for the year ended December 31, 2023.

Non-GAAP Financial Measures

In accordance with SEC rules, the Company provides descriptions of the non-GAAP financial measures included in this filing and reconciliations to the most closely related GAAP financial measures. The Company believes that these measures provide useful perspective on underlying business trends and results and a supplemental measure of year-over-year results. The non-GAAP financial measures described below are used by management in making operating decisions, allocating financial resources and for business strategy purposes and may, therefore, also be useful to investors as they are a view of our business results through the eyes of management. These non-GAAP financial measures are not intended to be considered by the user in place of the related GAAP financial measure, but rather as supplemental information to our business results. These non-GAAP financial measures may not be the same as similar measures used by other companies due to possible differences in method and in the items or events being adjusted.

References in this Management’s Discussion and Analysis of Financial Condition and Results of Operations to “organic sales” refer to sales calculated in accordance with GAAP, adjusted to exclude divestiture, exit, and acquisition-related sales. Management evaluates the Company’s sales performance based on organic sales growth. Organic sales growth is a non-GAAP financial measure of sales growth (which is the most directly comparable GAAP measure), adjusted to exclude the effects of divestiture, exit, and acquisition-related sales from year-over-year comparisons. The Company believes this measure provides investors with a supplemental understanding of underlying sales trends by providing sales growth on a consistent basis. The Company reports organic sales growth at the consolidated and segment levels.

The Company defines new orders as a contractual agreement between the Company and a third-party in which the Company will, or has the ability to, satisfy the performance obligations of the promised products or services under the terms of the agreement. The Company defines backlog as contractual commitments to customers for which the Company’s performance obligations have not been met, including with respect to new orders and contracts for which the Company has not begun any performance. Management utilizes new orders and backlog to evaluate the health of the industries in which the Company operates, the Company’s current and future results of operations and financial prospects, and strategies for business development. The Company believes that new orders and backlog are useful to investors as supplemental metrics by which to measure the Company’s current performance and prospective results of operations and financial performance.

Non-GAAP financial measures are not a substitute for GAAP financial results and should only be considered in conjunction with the Company’s financial information that is presented in accordance with GAAP.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

L.B. Foster Company carried out an evaluation, under the supervision and with the participation of the Company’s management, including the Chief Executive Officer and the Chief Financial Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) as of March 31, 2024. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective as of such date such that the information required to be disclosed by the Company in reports filed under the Exchange Act is (i) recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms and (ii) accumulated and communicated to management, including the chief executive officer, chief financial officer, or person performing such functions, as appropriate to allow timely decisions regarding disclosure.

25

Changes in Internal Control Over Financial Reporting

There were no changes to our “internal control over financial reporting” (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the three months ended March 31, 2024, and that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Limitations on Effectiveness of Controls and Procedures

In designing and evaluating disclosure controls and procedures and internal control over financial reporting, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures and internal control over financial reporting must reflect the fact that there are resource constraints and that management is required to apply judgment in evaluating the benefits of possible controls and procedures relative to their costs.

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, 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 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 Solutions 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 March 31, 2024				Three Months Ended March 31, 2023
	Net Sales		Segment Operating Profit (Loss)		Net Sales		Segment Operating Profit (Loss)
Rail, Technologies, and Services	$	82,623	$	6,778	$	64,384	$	2,388
Infrastructure Solutions	41,697		(1,393)		51,104		(356)
Total	$	124,320	$	5,385	$	115,488	$	2,032

Segment profit (loss) from operations, as shown above, includes allocated corporate operating expenses. Operating expenses related to corporate headquarter functions that directly support the segment activity are allocated 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. The expense allocation excludes certain corporate costs that are separately managed from the segments.

The following table demonstrates a reconciliation of reportable segment net profit to the Company’s consolidated total for the periods presented:

	Three Months Ended March 31,
	2024		2023
Operating profit for reportable segments	$	5,385	$	2,032
Interest expense - net	(1,125)		(1,388)
Other income (expense) - net	3,536		(1,827)
Unallocated corporate expenses and other unallocated charges	(3,102)		(1,529)
Income (loss) before income taxes	$	4,694	$	(2,712)

The following table illustrates assets of the Company by reportable segment for the periods presented:

	March 31, 2024		December 31, 2023
Rail, Technologies, and Services	$	167,565	$	157,023
Infrastructure Solutions	129,852		130,667
Unallocated corporate assets	28,984		25,516
Total	$	326,401	$	313,206

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 three months ended March 31, 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 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 Bedford, PA based operations supporting the product line expects to complete any remaining customer obligations during 2024. For the three months ended March 31, 2024 and 2023, the product line had $810 and $1,491 in sales, respectively. During the three months ended March 31, 2024, the Company incurred $73 of exit costs recorded in “Other (income) expense - net,” all of which were personnel expenses. The Company expects to incur an additional $111 of personnel expenses associated with the exit through 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, and $262 in other exit costs.

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.

Total net sales	$	124,320	$	115,488

The majority of the Company’s revenue is from products transferred and services rendered to customers at a point in time. 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 March 31, 2024
	Rail, Technologies, and Services		Infrastructure Solutions		Total
Point in time	$	65,539	$	29,657	$	95,196

Total net sales	$	64,384	$	51,104	$	115,488

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 months ended March 31, 2024, reductions to net sales stemming from changes in actual and expected values of certain commercial contracts and settlements of such contracts were immaterial. Such adjustments were $393 during the three months ended March 31, 2023. 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 for the year ended December 31, 2023.

Revenue recognized over time was as follows for the periods presented:

	Three Months Ended March 31,				Percentage of Total Net Sales Three Months Ended March 31,
	2024		2023		2024		2023
Over time input method	$	13,143	$	16,211	10.6	%	14.0	%

Total over time sales	$	29,124	$	32,526	23.4	%	28.2	%

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 March 31, 2024	$	2,889

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 March 31, 2024, the Company had approximately $222,261 of remaining performance obligations, which is also referred to as backlog. Approximately 10.5% of the March 31, 2024 backlog was related to projects that are anticipated to extend beyond March 31, 2025.

On November 17, 2023, the Company acquired Cougar Mountain Precast, LLC., for which all purchase accounting adjustments were finalized as of March 31, 2024. Purchase accounting finalization during the three months ended March 31, 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 March 31, 2024. However, future impairment charges could result if future projections diverge unfavorably from current expectations.

On August 13, 2021, the Company, its domestic subsidiaries, and certain of its Canadian and United Kingdom subsidiaries (collectively, the “Borrowers”), entered into the Fourth Amended and Restated Credit Agreement (the “Credit Agreement”) with PNC Bank, N.A., Citizens Bank, N.A., Wells Fargo Bank, National Association, Bank of America, N.A., and BMO Harris Bank, National Association. 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 March 31, 2024, the Company was in compliance with the covenants in the Credit Agreement, as amended, and had outstanding letters of credit of approximately $2,432.

Income Taxes

For the three months ended March 31, 2024 and 2023, the Company recorded an income tax expense of $289 on pre-tax income of $4,694 and an income tax benefit of $541 on pre-tax losses of $2,712, respectively, for an effective income tax rate of 6.2% and 19.9%, respectively. The Company's effective income tax rate for the three months ended March 31, 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 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 March 31, 2024 and December 31, 2023, the interest rate swaps were recorded in “Other current assets” when the interest rate swaps’ fair market value are in an asset position, and “Other accrued liabilities” when in a liability position within our Condensed Consolidated Balance Sheets.

	Fair Value Measurements at Reporting Date								Fair Value Measurements at Reporting Date
	March 31, 2024		Level 1		Level 2		Level 3		December 31, 2023		Level 1		Level 2		Level 3
Interest rate swaps	$	1,331	$	—	$	1,331	$	—	$	1,225	$	—	$	1,225	$	—
Total assets	$	1,331	$	—	$	1,331	$	—	$	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 March 31, 2024 and 2023, the Company recognized interest income of $337 and $245, respectively, from interest rate swaps.

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 $8,000, 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 March 31, 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 March 31, 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 March 31, 2024, no such disclosures were considered necessary.
