NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

(Dollars in thousands, except share data)

Note 1. Financial Statements

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 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all estimates and adjustments (consisting of normal recurring accruals, unless otherwise stated herein) considered necessary for a fair presentation of the financial position of L.B. Foster Company and subsidiaries as of June 30, 2019 and December 31, 2018, its Condensed Consolidated Statements of Operations and its Condensed Consolidated Statements of Stockholders' Equity for the three and six months ended June 30, 2019 and 2018, and its Condensed Consolidated Statements of Cash Flows for the six months ended June 30, 2019 and 2018, have been included. However, actual results could differ from those estimates. The results of operations for interim periods are not necessarily indicative of the results that may be expected for the year ending December 31, 2019. The Condensed Consolidated Balance Sheet as of December 31, 2018 was derived from audited financial statements. This Quarterly Report on Form 10-Q should be read in conjunction with the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018. 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.

Recently Issued Accounting Standards

In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. (“ASU”) 2018-15, “Intangibles - Goodwill and Other - Internal-Use Software” (“ASU 2018-15”). The ASU requires capitalization of certain implementation costs incurred in a cloud computing arrangement that qualifies as a service contract. The amendments in the ASU are effective for fiscal years beginning after December 15, 2019 and for interim periods therein with early adoption permitted. The Company is currently evaluating the potential impact of the ASU on its consolidated financial statements.

Recently Adopted Accounting Standards

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). The new accounting requirements include the accounting for, presentation of, and classification of leases. The guidance resulted in most leases being capitalized as a right-of-use asset with a related balance sheet liability. The requirements of the new standard are effective for annual reporting periods beginning after December 15, 2018, and interim periods within those annual periods. The Company adopted the provisions of ASU 2016-02 on January 1, 2019, using the modified retrospective approach as of the beginning of the period of adoption. Additionally, the Company has elected to apply the practical expedient package for leases that commenced prior to the effective date, not to apply the recognition requirements in the standard to short-term leases, and not to separate non-lease components from lease components. The Company has presented the disclosures required by ASU 2016-02 in Note 8.

In February 2018, the FASB issued ASU 2018-02, “Income Statement – Reporting Comprehensive Income; Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income” (“ASU 2018-02”), which allows companies to reclassify stranded tax effects caused by the US Tax Cuts and Jobs Act (the “Tax Act”) from accumulated other comprehensive income to retained earnings. The amendments eliminate the stranded tax effects resulting from the Tax Act and improve the usefulness of information reported to financial statement users. However, because the amendments only relate to the reclassification of the income tax effects of the Tax Act, the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from continuing operations is not affected. The Company adopted ASU 2018-02 during the first quarter of 2019 and has chosen to record the reclassification as of the beginning of the period of adoption. As a result of adopting this standard, we reclassified stranded tax effects of $633 from Accumulated other comprehensive loss to Retained earnings.

The SEC Disclosure Update and Simplification release announces the SEC's adoption of certain amendments in August 2018. While most of the amendments eliminate outdated or duplicative disclosure requirements, the final rule amends the interim financial statement requirements to require a reconciliation of changes in stockholders’ equity in the notes to the financial statements or as a separate statement. This analysis should reconcile the beginning balance to the ending balance of each caption in stockholders’ equity for each period for which an income statement is required to be filed and comply with the remaining content requirements of Rule 3-04 of Regulation S-X. As a result, registrants are required to provide the reconciliation for both the comparable quarterly and year-to-date periods in their Quarterly Reports on Form 10-Q but only for the year-to-date periods in registration statements, beginning in the first quarter of 2019. The Company has included the reconciliation of changes in stockholders’ equity as a separate statement.

Note 2. Business Segments

The Company is a leading manufacturer and distributor of products and services for transportation and energy infrastructure with locations in North America and Europe. The Company is organized and operates in three different operating segments: the Rail Products and Services segment, the Construction Products segment, and the Tubular and Energy Services segment. The 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 makes 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 the same as those 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, 2018.

The following table illustrates the Company's revenues and profit from operations by segment for the periods indicated:

	Three Months Ended June 30, 2019				Three Months Ended June 30, 2018
	Net Sales		Segment Profit		Net Sales		Segment Profit
Rail Products and Services	$	101,401	$	7,919	$	91,884	$	5,308
Construction Products	55,406		3,413		42,207		2,857
Tubular and Energy Services	44,126		5,019		38,799		4,545
Total	$	200,933	$	16,351	$	172,890	$	12,710
	Six Months Ended June 30, 2019				Six Months Ended June 30, 2018
	Net Sales		Segment Profit		Net Sales		Segment Profit
Rail Products and Services	$	177,095	$	11,398	$	154,054	$	7,356
Construction Products	92,751		4,247		71,107		2,875
Tubular and Energy Services	81,556		9,707		70,183		6,430
Total	$	351,402	$	25,352	$	295,344	$	16,661

Segment profit 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 provides a reconciliation of segment net profit from operations to the Company’s consolidated total:

	Three Months Ended June 30,				Six Months Ended June 30,
	2019		2018		2019		2018
Profit for reportable segments	$	16,351	$	12,710	$	25,352	$	16,661
Interest expense - net	(1,597)		(1,630)		(2,952)		(3,517)
Other income (expense)	252		(128)		402		477
Unallocated corporate expenses and other unallocated charges	(3,757)		(4,790)		(7,225)		(8,792)
Income before income taxes	$	11,249	$	6,162	$	15,577	$	4,829

The following table illustrates assets of the Company by segment:

	June 30, 2019		December 31, 2018
Rail Products and Services	$	188,924	$	175,704
Construction Products	107,025		97,133
Tubular and Energy Services	93,457		90,402
Unallocated corporate assets	27,404		20,010

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. Revenue recognized over time using an input measure was $34,984 and $29,583 for the three months ended June 30, 2019 and 2018, respectively, and $66,821 and $54,144 for the six months ended June 30, 2019 and 2018, respectively. A certain portion of the Company’s revenue recognized over time under these long-term agreements is recognized using an output method, specifically units delivered, based upon certain customer acceptance and delivery requirements. Revenue recognized over time using an output measure was $13,611 and $10,893 for the three months ended June 30, 2019 and 2018, respectively, and $23,522 and $17,554 for the six months ended June 30, 2019 and 2018, respectively. As of June 30, 2019 and December 31, 2018, the Company had contract assets of $37,457 and $26,692, respectively, that were recorded in “Inventories - net” within the Condensed Consolidated Balance Sheets. As of June 30, 2019 and December 31, 2018, the Company had contract liabilities of $2,162 and $1,505, respectively, that were recorded in “Deferred revenue” within the Condensed Consolidated Balance Sheets.

The majority of the Company’s revenue is from products transferred and services rendered to customers at a point in time. Point in time revenue accounted for 75.8% and 76.6% of revenue for the three months ended June 30, 2019 and 2018, respectively, and 74.3% and 75.7% of revenue for the six months ended June 30, 2019 and 2018. 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 its physical location.

The following table summarizes the Company's net sales by major product and service category:

The timing of revenue recognition, billings, and cash collections results in billed receivables, costs in excess of billings (contract assets, included in “Inventories - net”), and billings in excess of costs (contract liabilities, included in “Deferred revenue”) on the Condensed Consolidated Balance Sheets.

Significant changes in contract assets during the six months ended June 30, 2019 resulted from transfers to receivables from contract assets recognized at the beginning of the period of $19,764. Significant changes in contract liabilities during the six months ended June 30, 2019 resulted from increases of $2,016 due to billings in excess of costs, excluding amounts recognized as revenue during the period, and reductions due to revenue recognized during the three months ended June 30, 2019 and 2018 of $318 and $339, respectively, and reductions due to revenue recognized during the six months ended June 30, 2019 and 2018 of $1,266 and $740, respectively, that was included in the contract liability at the beginning of each period.

As of June 30, 2019, the Company had approximately $209,324 of remaining performance obligations, which is also referred to as backlog. Approximately 11.2% of the June 30, 2019 backlog was related to projects that are anticipated to extend beyond June 30, 2020.

Note 4. Goodwill and Other Intangible Assets

The following table presents the goodwill balance by reportable segment:

	Rail Products and Services		Construction Products		Tubular and Energy Services		Total

Balance as of June 30, 2019	$	14,072	$	5,147	$	—	$	19,219

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. No interim goodwill impairment test was required in connection with the evaluation of qualitative factors as of June 30, 2019.

Intangible assets are amortized over their useful lives, which range from 4 to 25 years, with a total weighted average amortization period of approximately 15 years as of June 30, 2019. Amortization expense was $1,679 and $1,775 for the three months ended June 30, 2019 and 2018, respectively, and $3,391 and $3,560 for the six months ended June 30, 2019 and 2018, respectively. During the three and six months ended June 30, 2019, certain fully amortized intangible assets related to non-compete agreements of $124 were eliminated from gross intangible assets and accumulated amortization.

As of June 30, 2019, estimated amortization expense for the remainder of 2019 and thereafter was as follows:

	Amortization Expense
Remainder of 2019	$	3,215
2020	5,856

Note 5. Accounts Receivable

Credit is extended based upon an evaluation of the customer’s financial condition and, while collateral is not required, the Company periodically receives surety bonds that guarantee payment. Credit terms are consistent with industry standards and practices. The amounts of trade accounts receivable as of June 30, 2019 and December 31, 2018 have been reduced by an allowance for doubtful accounts of $1,357 and $932, respectively. Changes in reserves for uncollectable accounts, which are recorded as part of “Selling and administrative expenses” in the Condensed Consolidated Statements of Operations, resulted in expense of $4 and income of $473 for the three months ended June 30, 2019 and 2018, respectively, and expense of $104 and income of $719 for the six months ended June 30, 2019 and 2018, respectively.

Note 7. Property, Plant, and Equipment

Property, plant, and equipment as of June 30, 2019 and December 31, 2018 consisted of the following:

	June 30, 2019		December 31, 2018
Land	$	12,443	$	12,440
Improvements to land and leaseholds	17,580		17,610
Buildings	36,474		34,608
Machinery and equipment, including equipment under finance leases	122,596		120,914
Construction in progress	2,692		3,083
Gross property, plant, and equipment	191,785		188,655
Less accumulated depreciation and amortization, including accumulated amortization of finance leases	(107,344)		(101,798)
Property, plant, and equipment - net	$	84,441	$	86,857

Depreciation expense was $2,768 and $2,938 for the three months ended June 30, 2019 and 2018, respectively, and $5,540 and $5,882 for the six months ended June 30, 2019 and 2018, respectively.

We review our property, plant, and equipment for recoverability whenever events or changes in circumstances indicate that carrying amounts may not be recoverable. We recognize an impairment loss if the carrying amount of a long-lived asset is not recoverable and exceeds its fair value. There were no impairments of property, plant, and equipment during the six months ended June 30, 2019 and 2018.

Note 8. Leases

On January 1, 2019, the Company adopted ASU 2016-02 and all the related amendments using the modified retrospective approach, which resulted in an increase in assets of $13,585 and an increase in current and long-term liabilities of $3,322 and $10,263, respectively. This adoption did not affect our results of operations, cash flows, or our compliance with the covenants of the Amended and Restated Credit Agreement dated March 13, 2015, and as amended by the Second Amendment dated November 7, 2016, or the covenants of the Third Amended and Restated Credit Agreement dated April 30, 2019.

We determine if an arrangement is a lease at its inception. Operating leases are included in “Operating lease right-of-use assets,” “Other current liabilities,” and “Long-term operating lease liabilities” within our Condensed Consolidated Balance Sheets. Finance leases are included in “Property, plant, and equipment - net,” “Current maturities of long-term debt,” and “Long-term debt” in our Condensed Consolidated Balance Sheets.

Right-of-use assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the commencement date in determining the present value of the lease payments. We use the implicit rate when readily determinable. The operating lease right-of-use asset also includes indirect costs incurred and lease payments made prior to the commencement date, less any lease incentives received. Our lease terms may include options to extend or terminate the lease and will be recognized when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

We have lease agreements with lease and non-lease components which we account for as a single lease component. Also, for certain equipment leases, we apply a portfolio approach to effectively account for the operating lease right-of-use assets and liabilities.

Finance lease and lessor accounting recognition has remained substantially unchanged under ASU 2016-02 and had no impact on the Company's balance sheet, results of operations, or cash flows as a result of the adoption of ASU 2016-02.

The Company has operating and finance leases for manufacturing facilities, corporate offices, sales offices, vehicles, and certain equipment. As of June 30, 2019, our leases had remaining lease terms of 1 to 13 years, some of which include options to extend the leases for up to 5 years, and some of which include options to terminate the leases within 1 year. As of June 30, 2019, the Company’s operating leases had a weighted average remaining lease term of 6 years and a weighted average discount rate of 4.9%. As of June 30, 2019, the Company’s finance leases had a weighted average remaining lease term of 1 year and a weighted average discount rate of 4.3%.

On April 30, 2019, the Company, its domestic subsidiaries, and certain of its Canadian and European subsidiaries (collectively, the “Borrowers”), entered into the Third Amended and Restated Credit Agreement (“Amended Credit Agreement”) with PNC Bank, N.A., Bank of America, N.A., Wells Fargo Bank, N.A., Citizens Bank, N.A., and BMO Harris Bank, N.A. This Amended Credit Agreement modifies the prior revolving credit facility which had a maximum credit line of $195,000 and extends the maturity date from March 13, 2020 to April 30, 2024. The Amended Credit Agreement provides for a five-year, revolving credit facility that permits aggregate borrowings of the Borrowers up to $140,000 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 Amended Credit Agreement’s incremental loan feature permits the Company to increase the available revolving borrowings under the facility by up to an additional $50,000 and provides for additional term loan borrowings of up to $25,000 subject to the Company’s receipt of increased commitments from existing or new lenders and the satisfaction of certain conditions.

The Company’s and the domestic, Canadian, and United Kingdom guarantors’ (the “Guarantors”) obligations under the Amended Credit Agreement are secured by the grant of a security interest by the Borrowers and Guarantors in substantially all of the personal property owned by such entities. Additionally, the equity interests in each of the loan parties, other than the Company, and the equity interests held by each loan party in their domestic subsidiaries, have been pledged to the lenders as collateral for the lending obligations.

Borrowings under the Amended Credit Agreement bear interest at rates based upon either the base rate or Euro-rate plus applicable margins. Applicable margins are dictated by the ratio of the Company’s total net indebtedness to the Company’s consolidated EBITDA for four trailing quarters, as defined in the Amended Credit Agreement. The base rate is the highest of (a) the Overnight Bank Funding Rate plus 50 basis points, (b) the Prime Rate, or (c) the Daily Euro-rate plus 100 basis points (each as defined in the Amended Credit Agreement). The base rate and Euro-rate spreads range from 25 to 125 basis points and 125 to 225 basis points, respectively.

The Amended Credit Agreement includes three financial covenants: (a) Maximum Gross Leverage Ratio, defined as the Company’s consolidated Indebtedness 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 Amended Credit Agreement, and (ii) 3.50 to 1.00 for all testing periods occurring during an Acquisition Period; (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 Amended Credit Agreement, which must be less than 1.25 to 1.00; and (c) Minimum Working Capital to Revolving Facility Usage Ratio, defined as the sum of the inventory and

16

accounts receivable of the Borrowers and certain other Guarantors divided by the Revolving Facility Usage, as defined in the Amended Credit Agreement, which must be less than 1.40 to 1.00.

The Amended Credit Agreement permits the Company to pay dividends and make distributions and redemptions with respect to its stock provided no event of default or potential default (as defined in the Amended Credit Agreement) has occurred prior to or after giving effect to the dividend, distribution, or redemption. Additionally, the Amended Credit Agreement permits the Company to complete acquisitions so long as (a) no event of default or potential default has occurred prior to or as a result of such acquisition; (b) the liquidity of the Borrowers is not less than $25,000 prior to giving effect to such acquisition; and (c) the aggregate consideration for the acquisition does not exceed: (i) $50,000 per acquisition; (ii) $50,000 in the aggregate for multiple acquisitions entered into during four consecutive quarters; and (iii) $100,000 in the aggregate over the term of the Amended Credit Agreement.

Other restrictions exist at all times including, but not limited to, limitations on the Company’s sale of assets and the incurrence by either the Borrowers or the non-borrower subsidiaries of the Company of other indebtedness, guarantees, and liens.

As of June 30, 2019, L.B. Foster was in compliance with the Amended Credit Agreement’s covenants.

As of June 30, 2019, the Company had outstanding letters of credit of approximately $836 and had net available borrowing capacity of $73,841. The maturity date of the facility is April 30, 2024.

On April 29, 2019, the credit facility with NatWest Bank for the Company's United Kingdom operations was terminated.

Note 10. 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.

Cash equivalents - Included within “Cash and cash equivalents” are investments in non-domestic term deposits. The carrying amounts approximate fair value because of the short maturity of the instruments.

LIBOR-based interest rate swaps - To reduce the impact of interest rate changes on outstanding variable-rate debt, the Company entered into forward starting LIBOR-based interest rate swaps with notional values totaling $50,000. The fair value of the interest rate swaps is 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, 2019, the interest rate swaps were recorded within “Other accrued liabilities.”

	Fair Value Measurements at Reporting Date								Fair Value Measurements at Reporting Date
	June 30, 2019		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		December 31, 2018		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)

The interest rate swaps 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 of our debt. The gains and losses related to the interest rate swaps are

17

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, 2019 and 2018, we recognized interest income of $56 and $1, respectively, and for the six months ended June 30, 2019 and 2018, we recognized interest income of $121 and interest expense of $34, respectively, from interest rate swaps.

In accordance with the provisions of ASC 820, “Fair Value Measurement,” the Company measures certain nonfinancial assets and liabilities at fair value, which are recognized or disclosed on a nonrecurring basis.

The Company applies the provisions of ASC 718, “Compensation – Stock Compensation,” to account for the Company’s stock-based compensation. Stock-based compensation cost is measured at the grant date based on the calculated fair value of the award and is recognized over the employees’ requisite service periods. The Company recorded stock compensation expense related to restricted stock awards and performance share units of $1,179 and $822 for the three months ended June 30, 2019 and 2018, respectively, and $2,034 and $1,904 for the six months ended June 30, 2019 and 2018, respectively. As of June 30, 2019, unrecognized compensation expense for unvested awards approximated $6,293. The Company will recognize this expense over the upcoming 3.8 years through April 2023.

Shares issued as a result of vested stock-based compensation awards generally will be from previously issued shares that have been reacquired by the Company and held as treasury stock or authorized and previously unissued common stock.

Restricted Stock Awards and Performance Share Units

Under the 2006 Omnibus Plan, the Company grants eligible employees restricted stock and performance 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 agreement. Since May 2018, awards of restricted stock are subject to a minimum one-year vesting period, including those granted to non-employee directors. Prior to May 2018, awards to non-employee directors were made in fully-vested shares. Performance share units are offered annually under separate three-year long-term incentive programs. Performance share units are subject to forfeiture and will be converted into common stock of the Company based upon the Company’s performance relative to performance measures and conversion multiples, as defined in the underlying program. If the Company’s estimate of the number of performance share units expected to vest changes in a subsequent accounting period, cumulative compensation expense could increase or decrease. The change will be recognized in the current period for the vested shares and would change future expense over the remaining vesting period.

Since May 1, 2017, non-employee directors have been permitted to defer receipt of annual stock awards and equity elected to be received in lieu of quarterly cash compensation. If so elected, these deferred stock units will be issued as common stock six months

18

after separation from their service on the Board of Directors. Since May 2018, there have been no non-employee directors who elected the option to receive deferred stock units of the Company’s common stock in lieu of director cash compensation.

In February 2019, the Compensation Committee approved the 2019 Performance Share Unit Program and the Executive Annual Incentive Compensation Plan (consisting of cash and equity components). The Compensation Committee also certified the actual Company performance achievement in the 2016 Performance Share Unit Program, which actual performance resulted in no payout relative to the 2016 Performance Share Unit Program target performance metrics.

The following table summarizes the restricted stock awards, deferred stock units, and performance share units activity for the six months ended June 30, 2019:

	Restricted Stock	Deferred Stock Units	Performance Share Units	Weighted Average Grant Date Fair Value
Outstanding as of December 31, 2018	191,825	41,774	300,373	$	18.61

Note 13. 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 (“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 two defined contribution plans for its employees in Canada, as well as one post-retirement benefit plan. The Company also maintains two defined contribution plans and one defined benefit plan for its employees in the United Kingdom.

Note 14. 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.

The following table sets forth the Company’s product warranty accrual:

	Warranty Liability
Balance as of December 31, 2018	$	2,057

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. The Company and a predecessor owned and operated a facility near the harbor site for a period prior to 1982. By letter dated March 16, 2018, the EPA informed the Company of the proposed schedule for consent decree negotiations to implement the Portland Harbor Superfund Site Record of Decision, with negotiations scheduled to commence by the end of 2019, and the EPA also set a proposed deadline of June 2019 to conclude negotiations with PRPs for the performance of remedial design work in the harbor. 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. 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, a private allocation process among numerous PRPs in a working group is ongoing. We cannot predict the ultimate impact of these proceedings because of the large number of PRPs involved throughout the harbor 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, 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 of June 30, 2019 and December 31, 2018, the Company maintained environmental reserves approximating $6,078 and $6,128, respectively. The following table sets forth the Company’s environmental obligation:

	Environmental liability
Balance as of December 31, 2018	$	6,128
Additions to environmental obligations	3
Environmental obligations utilized	(53)
Balance as of June 30, 2019	$	6,078

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, 2019.

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, 2019, no such disclosures were considered necessary.

21

Note 15. Income Taxes

For the three months ended June 30, 2019 and 2018, the Company recorded an income tax provision of $1,685 and $728 on pre-tax income of $11,249 and $6,162, respectively, for an effective income tax rate of 15.0% and 11.8%, respectively. For the six months ended June 30, 2019 and 2018, the Company recorded an income tax provision of $2,323 and $1,253 on pre-tax income of $15,577 and $4,829, respectively, for an effective income tax rate of 14.9% and 25.9%, respectively. The Company's effective tax rate for the three and six months ended June 30, 2019 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 continued 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 and the mix of income across jurisdictions could also impact the effective income tax rate.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

(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 are located in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” (“MD&A”). 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 current expectations and assumptions about future events that involve inherent risks and uncertainties and may concern, among other things, L.B. Foster Company’s (the “Company’s”) expectations relating to our strategy, goals, projections, and plans regarding our financial position, liquidity, capital resources, and results of operations; the outcome of litigation and product warranty claims; 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: environmental matters, including any costs associated with any remediation and monitoring; a resumption of the economic slowdown we experienced in previous years in the markets we serve; the risk of doing business in international markets; our ability to effectuate our strategy, including cost reduction initiatives, and our ability to effectively integrate acquired businesses and realize anticipated benefits; costs of and impacts associated with shareholder activism; a decrease in freight or passenger rail traffic; 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; the continuing effective 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 LIBOR 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 these amounts; foreign currency fluctuations; inflation; domestic and foreign government regulations, including tariffs; economic conditions and regulatory changes caused by the United Kingdom’s pending exit from the European Union, including the possibility of a “no-deal Brexit;” sustained declines in energy prices; 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. 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, 2018, or as updated and amended by Item 1A “Risk Factors,” in Part II of our Quarterly Reports on Form 10-Q filed 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.

Second Quarter 2019 Compared to Second Quarter 2018 – Company Analysis

Net sales of $200,933 for the three months ended June 30, 2019 increased by $28,043, or 16.2%, compared to the prior year quarter. The change was attributable to increases within each of our three segments. Construction Products sales increased by 31.3%, Tubular and Energy Services sales increased by 13.7%, and Rail Products and Services sales increased by 10.4%.

Gross profit increased by $4,065 compared to the prior year quarter to $37,128 for the three months ended June 30, 2019. Gross profit margin for the three months ended June 30, 2019 was 18.5%, or 60 basis points (“bps”) lower than the prior year quarter. The decrease in gross profit margin was primarily due to reductions of 250 bps and 150 bps within Construction Products and Tubular and Energy Services, respectively. The decreases were partially offset by an increase in gross profit margin of 90 bps within Rail Products and Services.

Selling and administrative expenses decreased by $513, or 2.2%, compared to the prior year quarter. The reduction was primarily driven by decreases in legal expenses of $2,007 related to the Union Pacific Railroad concrete tie litigation, which was partially offset by an increase of an aggregate of $1,288 related to third-party services, bad debt, and insurance expenses. As a percent of sales, selling and administrative expenses declined 210 bps compared to the prior year period.

The Company’s effective income tax rate for the three months ended June 30, 2019 was 15.0%, compared to 11.8% in the prior year quarter. For the three months ended June 30, 2019, the Company recorded a tax provision of $1,685, compared to $728 in the three

24

months ended June 30, 2018. The Company's effective tax rate for the three months ended June 30, 2019 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.

Net income for the second quarter of 2019 was $9,564, or $0.90 per diluted share, compared to $5,434, or $0.52 per diluted share, in the prior year quarter.

Second Quarter 2019 Compared to Second Quarter 2018

The Rail Products and Services segment sales increased by $9,517, or 10.4%, compared to the prior year quarter. The sales growth was driven by volume in our Rail Products business resulting in an increase of $13,658 primarily from our new rail, insulated joint, and domestic transit products. The increase was partially offset by a reduction of $4,141 in our Rail Technologies business, primarily attributable to reduced activity levels from the London Crossrail project as it nears completion.

The Rail Products and Services gross profit increased by $2,537, or 15.5%, over the prior year quarter. The increase was driven by volume growth in our Rail Products business. Segment gross profit margin grew by 90 bps as a result of the increased product mix contribution from our higher margin manufactured and service based offerings. Segment profit was $7,919, a $2,611 increase over the prior year quarter. Selling and administrative expenses incurred by the segment were flat to the prior year quarter and as a percent of sales were reduced 110 bps as the segment continued its focus on cost containment while increasing sales volume.

During the current quarter, the Rail Products and Services segment had a decrease in new orders of 32.9% compared to the prior year period. The decrease was primarily related to activity within our new rail distribution products.

Construction Products

	Three Months Ended June 30,						Increase/(Decrease)			Percent Increase/(Decrease)

Second Quarter 2019 Compared to Second Quarter 2018

The Construction Products segment sales increased by $13,199, or 31.3%, compared to the prior year quarter. The growth was attributable to volume increases in both Piling and Fabricated Bridge and Precast Concrete Products resulting in sales increases of $11,742 and $1,457, respectively. Piling continued product fulfillment during the current quarter attributable to a significant 2018 order, while Fabricated Bridge experienced increased volume within its steel decking and railing product lines. Our Precast Concrete Products business unit was favorably impacted by concrete building sales driven from municipalities while demand from federal and state agencies declined.

The Construction Products gross profit increased $853, or 12.1%, over the prior year quarter. The increase was primarily attributable to the sales volume growth within our Piling division and was partially offset by a reduction in Precast Concrete Products. Segment profit increased by $556 over the prior year quarter to 6.2% of net sales. Selling and administrative expenses incurred by the segment

25

increased by $300 over the prior year quarter; however, the expenses were reduced by 180 bps as a percentage of segment sales compared to the prior year quarter.

During the quarter, the Construction Products segment had an increase in new orders of 13.0% compared to the prior year quarter, which was primarily related to the Piling and Precast Concrete Products divisions.

Tubular and Energy Services

	Three Months Ended June 30,						Increase/(Decrease)			Percent Increase/(Decrease)
	2019			2018			2019 vs. 2018			2019 vs. 2018

Segment profit percentage	11.4		%	11.7		%	(0.3)		%	(2.9)	%

Second Quarter 2019 Compared to Second Quarter 2018

Tubular and Energy Services segment sales increased by $5,327, or 13.7%, compared to the prior year period. The increase was due to improvements primarily from Protective Coatings and Measurement Systems when compared to the prior year quarter. This was additionally supported by strong orders within the midstream market during the current quarter.

Tubular and Energy Services segment gross profit increased by $675, or 7.0%, which was supported by the sales growth in Protective Coatings and Measurement Systems. Segment gross profit margin decreased by 150 bps over the prior year quarter which was primarily driven by reduced volume within the Test, Inspection, and Threading Services business. Segment profit increased by $474, or 10.4%, over the prior year quarter. Selling and administrative expense increased by $754, which included a bad debt charge of $381 during the second quarter of 2019.

The Tubular and Energy Services segment had an increase of 31.5% in new orders compared to the prior year quarter. Orders for Protective Coatings and Measurement Systems increased by 68.4%, which was partially offset by a reduction in Test, Inspection, and Threading Services of 10.3%. The Company is encouraged with the continued growth of new orders within the segment, specifically related to the midstream market.

First Six Months 2019 Compared to First Six Months 2018 – Company Analysis

Net sales of $351,402 for the six months ended June 30, 2019 increased by $56,058, or 19.0%, compared to the prior year period. The change was attributable to increases within each of our three segments. Construction Products sales increased by 30.4%, Tubular and Energy Services sales increased by 16.2%, and Rail Products and Services sales increased by 15.0%.

Gross profit increased by $11,035 compared to the prior year period to $66,290 for the six months ended June 30, 2019. Gross profit margin for the six months ended June 30, 2019 was 18.9%, or 20 bps higher than the prior year period. The rise in gross profit margin was primarily due to increases of 150 bps and 30 bps within Tubular and Energy Services and Rail Products and Services, respectively. The increase was partially offset by a decrease in gross profit margin of 110 bps within the Construction Products segment.

Selling and administrative expenses increased by $946 or 2.2% from the prior year. The escalation was primarily driven by increases in personnel-related expenses of $1,544, third-party services of $1,099, and bad debt of $823. The increase was partially offset by a reduction in legal expenses related to the Union Pacific Railroad concrete tie litigation of $3,467. As a percent of sales, selling and administrative expenses declined by 210 bps compared to the prior year period.

Interest expense, net of interest income, decreased by $565, or 16.1%, as a result of the reduction in outstanding debt compared to the prior year period.

27

The Company’s effective income tax rate for the six months ended June 30, 2019 was 14.9%, compared to 25.9% in the prior year period. For the six months ended June 30, 2019, the Company recorded a tax provision of $2,323, compared to $1,253 in the six months ended June 30, 2018. The Company's effective tax rate for the six months ended June 30, 2019 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.

Net income for the six months ended June 30, 2018 was $13,254, or $1.25 per diluted share, compared to $3,576, or $0.34 per diluted share, in the prior year period.

First Six Months 2019 Compared to First Six Months 2018

The Rail Products and Services segment sales increased by $23,041, or 15.0%, compared to the prior year period. The sales growth was driven by our Rail Products business unit which increased by $23,830. The Rail Products growth was primarily attributable to North American new rail distribution volume and, to a lesser extent, transit and insulated joint products. Partially offsetting the increase was a decline in sales within the European transit market as we approach the completion of the London Crossrail project.

The Rail Products and Services gross profit increased by $4,850, or 17.1%, over the prior year period. The increase was driven by volume growth in Rail Products. Segment gross profit margin increased by 30 bps as a result of the increased contribution from higher margin product mix within Rail Products. Segment profit was $11,398, a $4,042 increase compared to the prior year period. Selling and administrative expenses incurred by the segment as a percent of sales was reduced 150 bps compared to the prior year period as the segment continued its focus on cost containment while increasing sales volume.

During the current year, the Rail Products and Services segment had a decrease in new orders of 16.9% compared to the prior year period. Backlog was $94,026 as of June 30, 2019, a decrease of 25.9%, compared to $126,856 as of June 30, 2018. The decreases were primarily related to activity within our new rail distribution products.

First Six Months 2019 Compared to First Six Months 2018

The Construction Products segment sales increased by $21,644, or 30.4%, compared to the prior year period. The increase was attributable to growth within each of the businesses with the segment. Piling sales volume increased considerably during the current year as a significant 2018 order is fulfilled, while Fabricated Bridge experienced increased sales volume within its steel decking and railing product lines which resulted in an increase of $16,613. Our Precast Concrete Products business unit was favorably impacted by concrete building sales driven from municipalities.

The Construction Products gross profit increased $2,393, or 21.6%, over the prior year period. The increase was primarily attributable to the sales volume growth in both business units within the segment. Segment profit increased by $1,372 over the prior year period to 4.6% of net sales. Selling and administrative expenses incurred by the segment increased $1,025 over the prior year quarter; however, the expenses as a percentage of segment sales were reduced by 160 bps compared to the prior year period.

28

During the first half of 2019, the Construction Products segment had an increase in new orders of 1.7% compared to the prior year period, which was primarily related to Precast Concrete Products. The increase in new orders helped to provide the segment a strong backlog of $89,239 as of June 30, 2019, an 8.3% increase over the prior year period.

Tubular and Energy Services

First Six Months 2019 Compared to First Six Months 2018

Tubular and Energy Services segment sales increased by $11,373, or 16.2%, compared to the prior year period. The increase was due to significant growth from Protective Coatings and Measurement Systems when compared to the prior year period. This was additionally supported by strong orders within the midstream market during the current year.

Tubular and Energy Services segment gross profit increased $3,792, or 23.9%, which was supported by the sales growth in Protective Coatings and Measurement Systems. Segment gross profit margin improved by 150 bps over the prior year period which was primarily driven by volume and favorable production rates in the 2019 period within Protective Coatings and Measurement Systems. Segment profit increased by $3,277, or 51.0%, over the prior year period. While selling and administrative expense increased by $1,179, management was pleased with the segment's cost containment efforts, which, as a percentage of sales, remained flat compared to the prior year period.

The Tubular and Energy Services segment had an increase of 23.6% in new orders compared to the prior year period. Orders for Protective Coatings and Measurement Systems increased by 49.5%, which was partially offset by a reduction in Test, Inspection, and Threading Services of 7.7%. The increased order activity resulted in a backlog as of June 30, 2019 of $26,059, an 18.5% increase when compared to the prior year.

While a considerable portion of our business is backlog-driven, certain product lines within the Rail Products and Services and Tubular and Energy Services segments are not driven by backlog.

Liquidity and Capital Resources

Total debt was $91,115 and $74,982 as of June 30, 2019 and December 31, 2018, respectively, and was primarily comprised of borrowings under our revolving credit facility. Our need for liquidity relates primarily to working capital requirements for operations, capital expenditures, and debt service obligations.

Cash Flow from Operating Activities

During the six months ended June 30, 2019, cash flows used in operating activities were $9,429 compared to operations providing $7,902 during the prior year period. For the six months ended June 30, 2019, income and adjustments to income from operating activities provided $23,790 compared to $13,924 in the 2018 period. Working capital and other assets and liabilities used $33,219 in the current period compared to $6,022 in the prior year period. During the six months ended June 30, 2019, the Company made payments totaling $4,000 under the terms of the concrete tie settlement agreement with Union Pacific Railroad.

The Company’s calculation for days sales outstanding at June 30, 2019 and December 31, 2018 was 50 days, and we believe our receivables portfolio is strong.

Cash Flow from Investing Activities

Capital expenditures for the six months ended June 30, 2019 and 2018 were $3,848 and $1,816, respectively. The current year expenditures relate to plant expansion and automation integration programs within our Tubular and Energy Services segment as well as general plant and operational improvements throughout the Company. Expenditures for the six months ended June 30, 2018 related to expenditures for general plant and operational improvements. During the six months ended June 30, 2019, the Company received $76 in proceeds from the sale of certain property, plant, and equipment as compared to $2,086 in the prior year period.

Cash Flow from Financing Activities

During the six months ended June 30, 2019, the Company had an increase in outstanding debt of $16,133, primarily related to the funding of working capital for operations. During the six months ended June 30, 2018, the Company had a decrease in outstanding debt of $30,930, primarily related to payments against the revolving credit facility which was facilitated by the repatriation of $24,693 in excess cash from our international locations. Treasury stock acquisitions represent income tax withholdings from employees in connection with the vesting of restricted stock awards.

Financial Condition

As of June 30, 2019, we had $12,001 in cash and cash equivalents and a domestic credit facility with $73,841 of net availability while we had $91,115 in total debt. We believe this liquidity will provide the flexibility to operate the business in a prudent manner and enable us to continue to service our revolving credit facility.

Our cash management priority continues to be short-term maturities and the preservation of our principal balances. As of June 30, 2019, approximately $10,532 of our cash and cash equivalents was held in non-domestic bank accounts.

To reduce the impact of interest rate changes on outstanding variable-rate debt, the Company entered into forward starting LIBOR-based interest rate swaps with notional values totaling $50,000. The swaps became effective on February 28, 2017 at which point they effectively converted a portion of the debt from variable to fixed-rate borrowings during the term of the swap contract. As of June 30, 2019, the swap liability was $506 compared to an asset of $675 as of December 31, 2018.

On April 30, 2019, the Company, its domestic subsidiaries, and certain of its Canadian and European subsidiaries (collectively, the “Borrowers”), entered into the Third Amended and Restated Credit Agreement (“Amended Credit Agreement”) with PNC Bank, N.A., Bank of America, N.A., Wells Fargo Bank, N.A., Citizens Bank, N.A., and BMO Harris Bank, N.A. This Amended Credit Agreement modifies the prior revolving credit facility which had a maximum credit line of $195,000, and extends the maturity date from March 13, 2020 to April 30, 2024. The Amended Credit Agreement provides for a five-year, revolving credit facility that permits aggregate borrowings of the Borrowers up to $140,000 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 Amended Credit Agreement’s incremental loan feature permits the Company to increase the available revolving borrowings under the facility by up to an additional $50,000 and provides for additional term loan borrowings of up to $25,000 subject to the Company’s receipt of increased commitments from existing or new lenders and the satisfaction of certain conditions.

For a discussion of the terms and availability of the Company's credit facilities, please refer to Note 9 of the Notes to Condensed Consolidated Financial Statements contained in the Quarterly Report on Form 10-Q.

Critical Accounting Policies

The Condensed Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States. When more than one accounting principle, or method of its application, is generally accepted, management selects the principle or method that, in its opinion, is appropriate in the Company’s specific circumstances. Application of these accounting principles requires management to reach opinions regarding estimates about the future resolution of existing uncertainties. As a result, actual results could differ from these estimates. In preparing these financial statements, management has reached its opinions regarding the best estimates and judgments of the amounts and disclosures included in the financial statements giving due regard to materiality. We have updated our lease policies since December 31, 2018, in conjunction with our adoption of Accounting Standards Codification 842, “Leases” (“ASC 842”) as further described in Note 8 of the Notes to Condensed Consolidated Financial Statements contained in this Quarterly Report on Form 10-Q. A summary of the Company’s critical accounting policies and estimates is included in Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations -Critical Accounting Policies and Estimates in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018.

Off-Balance Sheet Arrangements

The Company’s off-balance sheet arrangements include purchase obligations and standby letters of credit. A schedule of the Company’s required payments under financial instruments and other commitments as of December 31, 2018 is included in Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations -Liquidity and Capital Resources -Tabular Disclosure of Contractual Obligations in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018. On January 1, 2019, the Company adopted the provisions under ASC 842. As a result of the adoption, operating leases that were previously off-balance sheet arrangements are now recognized as right-of-use assets and liabilities within the Condensed Consolidated Balance Sheets. There were no other material changes to these off-balance sheet arrangements during the current quarter. These arrangements provide the Company with increased flexibility relative to the utilization and investment of cash resources.

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 June 30, 2019. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective 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.

Changes in Internal Control Over Financial Reporting

On January 1, 2019, the Company adopted the standards of Accounting Standards Codification 842, “Leases” (“ASC 842”). The adoption of ASC 842 required the Company to implement changes to our processes related to operating lease recognition and the control activities within them. This included the development of new policies and procedures, ongoing lease review and evaluation processes, and implementation of processes to obtain information responsive to the new disclosure requirements. There were no other 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 six months ended June 30, 2019, 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 the 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.

Exhibit 10.2

RESTRICTED STOCK AGREEMENT

(Non-employee DIRECTOR)

(Section 5.1 Of The Omnibus Incentive Plan, as Amended and Restated)

This Restricted Stock Agreement set forth below (this “Agreement”) is dated as of May ____, 2019 (the “Issue Date”) and is between L. B. Foster Company, a Pennsylvania corporation (“Company”), and [NAME] (the “Shareholder”).

The Company has established its 2006 Omnibus Incentive Plan, as Amended and Restated (the “Plan”), to advance the interests of the Company and its Shareholders by providing incentives to certain eligible persons who contribute significantly to the strategic and long-term performance objectives and growth of the Company. All capitalized terms not otherwise defined in this Agreement have the same meaning given them in the Plan.

Pursuant to the provisions of the Plan, the Committee has full power and authority to direct the execution and delivery of this Agreement in the name and on behalf of the Company, and has authorized the execution and delivery of this Agreement.

AGREEMENT

The parties, intending to be legally bound hereby, agree as follows:

Section 1.Issuance of Stock. Subject and pursuant to all terms and conditions stated in this Agreement and in the Plan, as of the Issue Date, the Company hereby grants to Shareholder [# OF RESTRICTED SHARES] shares of Company common stock, par value $0.01 per share (the “Common Stock”) pursuant to Article V of the Plan. For purposes of this Agreement, the “Shares” shall include all of the shares of Common Stock issued to Shareholder pursuant to this Agreement or issued with respect to such shares of Common Stock, including, but not limited to, shares of Company capital stock issued by way of a stock dividend or stock split or in connection with a combination of shares, recapitalization, merger, consolidation or other reorganization.

Section 2.Vesting; Rights; Obligations; and Restrictions on Transfer.

(a)None of the Shares may be sold, transferred, pledged, hypothecated or otherwise encumbered or disposed of until they have vested in accordance with the terms of this Section 2. Except as set forth in this Section 2, effective at the close of business on the date Shareholder ceases to be a Director for any reason other than as set forth in this Agreement, any Shares that are not vested in accordance with this Section 2, and any dividends accrued pursuant to Section 2(c) below, shall be automatically forfeited without any further obligation on the part of the Company. Shareholder hereby assigns and transfers any forfeited Shares and the stock certificate(s) or other evidence of ownership representing such Shares to the Company.

(b)All of the Shares will vest 100% on the earlier of the (i) first anniversary of the Issue Date or (ii) date of the Company’s next Annual Meeting of Shareholders which occurs after the Issue Date (the “Vesting Date”), subject to Shareholder’s continued service as a Director of the Company until such Vesting Date. However, any unvested Shares shall immediately vest in full upon the occurrence of the following events if such event(s) occur(s) prior to the Vesting Date: (i) Shareholder experiences a Separation from Service as a Director due to Shareholder’s death or Disability; or (ii) a Change in Control, unless the acquiring entity in such Change in Control assumes this Agreement and converts the Shares into a substantially comparable award of capital stock or other equity incentive instrument in such acquiring entity as determined by the Board and with such shares or equivalent continuing to vest on the Vesting Date regardless of whether such Director experiences a Separation from Service between the date of the Change in Control and the Vesting Date.

(c)Subject to the foregoing provisions of this Section 2 and the provisions of the Plan, Shareholder shall have all rights of a shareholder with respect to the Shares, including the right to vote the Shares and to receive dividends, provided, however, that until such time as the Shares, or portion thereof, shall have vested, the Company shall accrue on its books and records for the benefit of the Shareholder an amount equal to the dividend payment that would otherwise have been received on the Shares but for this Agreement to accrue the dividend payments. Dividends accrued for the benefit of the Shareholder shall be payable as the Shares vest with payment to be made by the Company, or its agent, within ten (10) business days after vesting.

(d)The certificates, if any, representing unvested Shares will bear the following or similar legend:

“The securities represented by this certificate are subject to forfeiture and restrictions on transfer as set forth in the Restricted Stock Agreement between the issuer and the initial holder of these shares. A copy of that document may be obtained by the holder without charge at the issuer’s principal place of business or upon written request.”

Section 3.Investment Representation. Shareholder hereby acknowledges that the Shares cannot be sold, transferred, assigned, pledged or hypothecated in the absence of an effective registration statement for the Shares under the Securities Act of 1933, as amended (the “Securities Act”), and applicable state securities laws or an applicable exemption from the registration requirements of the Securities Act and any applicable state securities laws or as otherwise provided herein or in the Plan. Shareholder also agrees that the Shares which Shareholder acquires pursuant to this Agreement will not be sold or otherwise disposed of in any manner which would constitute a violation of any applicable securities laws, whether federal or state.

Section 4.Book Entry Account. At the discretion of the Company, certificates for the Shares may not be issued. In lieu of certificates, the Company may establish a book entry account for the Shares, until vested, in the name of the Shareholder with the Company’s transfer agent for its Common Stock.

Section 5.Income Taxes.

(a)Shareholder acknowledges that, if Shareholder is a Pennsylvania resident, Shareholder is responsible for any and all applicable income and other taxes, as well as any social insurance contributions and other deductions or withholdings required by applicable law, from this Award, including federal, FICA, state, and local taxes applicable to Shareholder (such taxes, the “Tax-Related Items”).

(b)If Shareholder is not a Pennsylvania resident, Shareholder acknowledges that any issuance of Shares to Shareholder pursuant to this Award shall be subject to any applicable tax withholding requirements. The Company shall automatically, not later than the date as of which the transfer of Shares pursuant to this Award becomes a taxable event for federal income tax or other applicable withholding tax purposes, cause the required minimum federal, state, local, non-U.S., or other taxes required by law to be withheld on account of such taxable event to be satisfied by withholding from Shares to be issued to Shareholder a number of Shares with an aggregate Fair Market Value that would satisfy such minimum withholding obligation.

(c)Shareholder agrees further to notify the Company promptly if Shareholder files an election pursuant to Section 83(b) of the Internal Revenue Code of 1986, as amended (the “Code”), with respect to any Shares.

Section 6.No Right to Continued Service. Neither the Plan nor this Agreement shall be deemed to give Shareholder any right to continued service as a Director of the Company, nor shall the Plan or the Agreement be deemed to limit in any way the Company’s right to terminate the Shareholder’s service as a Director at any time.

Section 7.Further Assistance. Shareholder will provide assistance reasonably requested by the Company in connection with actions taken by Shareholder while serving as a Director of the Company, including but not limited to assistance in connection with any lawsuits or other claims against the Company arising from events during the period in which Shareholder served as a Director of the Company.

Section 8.Binding Effect; No Third Party Beneficiaries. This Agreement shall be binding upon and inure to the benefit of the Company and Shareholder and their respective heirs, representatives, successors and permitted assigns. This Agreement shall not confer any rights or remedies upon any person other than the Company and the Shareholder and their respective heirs, representatives, successors and permitted assigns. The parties agree that this Agreement shall survive the issuance of the Shares.

Section 9.Agreement to Abide by Plan; Conflict between Plan and Agreement. The Plan is hereby incorporated by reference into this Agreement and is made a part hereof as though fully set forth in this Agreement. Shareholder, by execution of this Agreement, represents that he or she is familiar with the terms and provisions of the Plan and agrees to abide by all of the terms and conditions of this Agreement and the Plan. Shareholder accepts as binding, conclusive and final all decisions or interpretations of the Committee upon any question arising under the Plan or this Agreement (including, without limitation, the date that Shareholder’s service as a Director of the Company terminates). In the event of any conflict between the Plan and this Agreement, the Plan shall control and this Agreement shall be deemed to be modified accordingly, except to the extent that the Plan gives the Committee the express authority to vary the terms of the Plan by means of this Agreement, in which case this Agreement shall govern.

Section 10.Entire Agreement. Except as otherwise provided herein, this Agreement and the Plan, which Shareholder has reviewed and accepted in connection with the grant of the Shares reflected by this Agreement, constitute the entire agreement between the parties and supersede any prior understandings, agreements, or representations by or between the parties, written or oral, to the extent they related in any way to the subject matter of this Agreement.

Section 11.Choice of Law. To the extent not superseded by federal law, the laws of the Commonwealth of Pennsylvania (without regard to the conflicts laws thereof) shall control in all matters relating to this Agreement and any action relating to this Agreement must be brought in State or Federal Courts located in the Commonwealth of Pennsylvania.

Section 12.Notice. All notices, requests, demands, claims, and other communications under this Agreement shall be in writing. Any notice, request, demand, claim, or other communication under this Agreement shall be deemed duly given if (and then two business days after) it is sent by registered or certified mail, return receipt requested, postage prepaid, and addressed to the intended recipient at the following address: If to the Company, L. B. Foster Company, 415 Holiday Drive, Pittsburgh, PA 15220, Attn: Secretary; and if to the Shareholder, to his or her address as it appears on the Company’s records.

Either party to this Agreement may change the address to which notices, requests, demands, claims, and other communications hereunder are to be delivered by giving the other party notice in the manner set forth in this section.

Section 13.Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original but all of which together shall constitute one and the same instrument.

Section 14.Amendments. This Agreement may be amended or modified at any time by an instrument in writing signed by the parties hereto, or as otherwise provided under the Plan. Notwithstanding, the Company may, in its sole discretion and without the Shareholder’s consent, modify or amend the terms of this Agreement, impose conditions on the timing and effectiveness of the issuance of the Shares, or take any other action it deems necessary or advisable, to cause this Award to be excepted from Section 409A of the Code (or to comply therewith to the extent the Company determines it is not excepted).

Financial Statements

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 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all estimates and adjustments (consisting of normal recurring accruals, unless otherwise stated herein) considered necessary for a fair presentation of the financial position of L.B. Foster Company and subsidiaries as of June 30, 2019 and December 31, 2018, its Condensed Consolidated Statements of Operations and its Condensed Consolidated Statements of Stockholders' Equity for the three and six months ended June 30, 2019 and 2018, and its Condensed Consolidated Statements of Cash Flows for the six months ended June 30, 2019 and 2018, have been included. However, actual results could differ from those estimates. The results of operations for interim periods are not necessarily indicative of the results that may be expected for the year ending December 31, 2019. The Condensed Consolidated Balance Sheet as of December 31, 2018 was derived from audited financial statements. This Quarterly Report on Form 10-Q should be read in conjunction with the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018. 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.

Recently Issued Accounting Standards

In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. (“ASU”) 2018-15, “Intangibles - Goodwill and Other - Internal-Use Software” (“ASU 2018-15”). The ASU requires capitalization of certain implementation costs incurred in a cloud computing arrangement that qualifies as a service contract. The amendments in the ASU are effective for fiscal years beginning after December 15, 2019 and for interim periods therein with early adoption permitted. The Company is currently evaluating the potential impact of the ASU on its consolidated financial statements.

Recently Adopted Accounting Standards

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). The new accounting requirements include the accounting for, presentation of, and classification of leases. The guidance resulted in most leases being capitalized as a right-of-use asset with a related balance sheet liability. The requirements of the new standard are effective for annual reporting periods beginning after December 15, 2018, and interim periods within those annual periods. The Company adopted the provisions of ASU 2016-02 on January 1, 2019, using the modified retrospective approach as of the beginning of the period of adoption. Additionally, the Company has elected to apply the practical expedient package for leases that commenced prior to the effective date, not to apply the recognition requirements in the standard to short-term leases, and not to separate non-lease components from lease components. The Company has presented the disclosures required by ASU 2016-02 in Note 8.

In February 2018, the FASB issued ASU 2018-02, “Income Statement – Reporting Comprehensive Income; Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income” (“ASU 2018-02”), which allows companies to reclassify stranded tax effects caused by the US Tax Cuts and Jobs Act (the “Tax Act”) from accumulated other comprehensive income to retained earnings. The amendments eliminate the stranded tax effects resulting from the Tax Act and improve the usefulness of information reported to financial statement users. However, because the amendments only relate to the reclassification of the income tax effects of the Tax Act, the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from continuing operations is not affected. The Company adopted ASU 2018-02 during the first quarter of 2019 and has chosen to record the reclassification as of the beginning of the period of adoption. As a result of adopting this standard, we reclassified stranded tax effects of $633 from Accumulated other comprehensive loss to Retained earnings.

The SEC Disclosure Update and Simplification release announces the SEC's adoption of certain amendments in August 2018. While most of the amendments eliminate outdated or duplicative disclosure requirements, the final rule amends the interim financial statement requirements to require a reconciliation of changes in stockholders’ equity in the notes to the financial statements or as a separate statement. This analysis should reconcile the beginning balance to the ending balance of each caption in stockholders’ equity for each period for which an income statement is required to be filed and comply with the remaining content requirements of Rule 3-04 of Regulation S-X. As a result, registrants are required to provide the reconciliation for both the comparable quarterly and year-to-date periods in their Quarterly Reports on Form 10-Q but only for the year-to-date periods in registration statements, beginning in the first quarter of 2019. The Company has included the reconciliation of changes in stockholders’ equity as a separate statement.

Segment Reporting [Abstract]

Business Segments

Business Segments

The Company is a leading manufacturer and distributor of products and services for transportation and energy infrastructure with locations in North America and Europe. The Company is organized and operates in three different operating segments: the Rail Products and Services segment, the Construction Products segment, and the Tubular and Energy Services segment. The 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 makes 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 the same as those 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, 2018.

The following table illustrates the Company's revenues and profit from operations by segment for the periods indicated:

	Three Months Ended June 30, 2019				Three Months Ended June 30, 2018
	Net Sales		Segment Profit		Net Sales		Segment Profit

Total	$	351,402	$	25,352	$	295,344	$	16,661

Segment profit 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 provides a reconciliation of segment net profit from operations to the Company’s consolidated total:

Revenue

Revenue

Revenue from products or services provided to customers over time accounted for 24.2% and 23.4% of revenue for the three months ended June 30, 2019 and 2018, respectively, and 25.7% and 24.3% of revenue for the six months ended June 30, 2019 and 2018, respectively. 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. Revenue recognized over time using an input measure was $34,984 and $29,583 for the three months ended June 30, 2019 and 2018, respectively, and $66,821 and $54,144 for the six months ended June 30, 2019 and 2018, respectively. A certain portion of the Company’s revenue recognized over time under these long-term agreements is recognized using an output method, specifically units delivered, based upon certain customer acceptance and delivery requirements. Revenue recognized over time using an output measure was $13,611 and $10,893 for the three months ended June 30, 2019 and 2018, respectively, and $23,522 and $17,554 for the six months ended June 30, 2019 and 2018, respectively. As of June 30, 2019 and December 31, 2018, the Company had contract assets of $37,457 and $26,692, respectively, that were recorded in “Inventories - net” within the Condensed Consolidated Balance Sheets. As of June 30, 2019 and December 31, 2018, the Company had contract liabilities of $2,162 and $1,505, respectively, that were recorded in “Deferred revenue” within the Condensed Consolidated Balance Sheets.

The majority of the Company’s revenue is from products transferred and services rendered to customers at a point in time. Point in time revenue accounted for 75.8% and 76.6% of revenue for the three months ended June 30, 2019 and 2018, respectively, and 74.3% and 75.7% of revenue for the six months ended June 30, 2019 and 2018. 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 its physical location.

The following table summarizes the Company's net sales by major product and service category:

The timing of revenue recognition, billings, and cash collections results in billed receivables, costs in excess of billings (contract assets, included in “Inventories - net”), and billings in excess of costs (contract liabilities, included in “Deferred revenue”) on the Condensed Consolidated Balance Sheets.

Significant changes in contract assets during the six months ended June 30, 2019 resulted from transfers to receivables from contract assets recognized at the beginning of the period of $19,764. Significant changes in contract liabilities during the six months ended June 30, 2019 resulted from increases of $2,016 due to billings in excess of costs, excluding amounts recognized as revenue during the period, and reductions due to revenue recognized during the three months ended June 30, 2019 and 2018 of $318 and $339, respectively, and reductions due to revenue recognized during the six months ended June 30, 2019 and 2018 of $1,266 and $740, respectively, that was included in the contract liability at the beginning of each period.

As of June 30, 2019, the Company had approximately $209,324 of remaining performance obligations, which is also referred to as backlog. Approximately 11.2% of the June 30, 2019 backlog was related to projects that are anticipated to extend beyond June 30, 2020.

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. No interim goodwill impairment test was required in connection with the evaluation of qualitative factors as of June 30, 2019.

The components of the Company’s intangible assets were as follows:

Leases [Abstract]

Leases, Operating

Leases

On January 1, 2019, the Company adopted ASU 2016-02 and all the related amendments using the modified retrospective approach, which resulted in an increase in assets of $13,585 and an increase in current and long-term liabilities of $3,322 and $10,263, respectively. This adoption did not affect our results of operations, cash flows, or our compliance with the covenants of the Amended and Restated Credit Agreement dated March 13, 2015, and as amended by the Second Amendment dated November 7, 2016, or the covenants of the Third Amended and Restated Credit Agreement dated April 30, 2019.

We determine if an arrangement is a lease at its inception. Operating leases are included in “Operating lease right-of-use assets,” “Other current liabilities,” and “Long-term operating lease liabilities” within our Condensed Consolidated Balance Sheets. Finance leases are included in “Property, plant, and equipment - net,” “Current maturities of long-term debt,” and “Long-term debt” in our Condensed Consolidated Balance Sheets.

Right-of-use assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the commencement date in determining the present value of the lease payments. We use the implicit rate when readily determinable. The operating lease right-of-use asset also includes indirect costs incurred and lease payments made prior to the commencement date, less any lease incentives received. Our lease terms may include options to extend or terminate the lease and will be recognized when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

We have lease agreements with lease and non-lease components which we account for as a single lease component. Also, for certain equipment leases, we apply a portfolio approach to effectively account for the operating lease right-of-use assets and liabilities.

Finance lease and lessor accounting recognition has remained substantially unchanged under ASU 2016-02 and had no impact on the Company's balance sheet, results of operations, or cash flows as a result of the adoption of ASU 2016-02.

The Company has operating and finance leases for manufacturing facilities, corporate offices, sales offices, vehicles, and certain equipment. As of June 30, 2019, our leases had remaining lease terms of 1 to 13 years, some of which include options to extend the leases for up to 5 years, and some of which include options to terminate the leases within 1 year. As of June 30, 2019, the Company’s operating leases had a weighted average remaining lease term of 6 years and a weighted average discount rate of 4.9%. As of June 30, 2019, the Company’s finance leases had a weighted average remaining lease term of 1 year and a weighted average discount rate of 4.3%.

The balance sheet component of the Company's leases were as follows as of June 30, 2019:

	June 30, 2019

Leases, Finance

Leases

On January 1, 2019, the Company adopted ASU 2016-02 and all the related amendments using the modified retrospective approach, which resulted in an increase in assets of $13,585 and an increase in current and long-term liabilities of $3,322 and $10,263, respectively. This adoption did not affect our results of operations, cash flows, or our compliance with the covenants of the Amended and Restated Credit Agreement dated March 13, 2015, and as amended by the Second Amendment dated November 7, 2016, or the covenants of the Third Amended and Restated Credit Agreement dated April 30, 2019.

We determine if an arrangement is a lease at its inception. Operating leases are included in “Operating lease right-of-use assets,” “Other current liabilities,” and “Long-term operating lease liabilities” within our Condensed Consolidated Balance Sheets. Finance leases are included in “Property, plant, and equipment - net,” “Current maturities of long-term debt,” and “Long-term debt” in our Condensed Consolidated Balance Sheets.

Right-of-use assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the commencement date in determining the present value of the lease payments. We use the implicit rate when readily determinable. The operating lease right-of-use asset also includes indirect costs incurred and lease payments made prior to the commencement date, less any lease incentives received. Our lease terms may include options to extend or terminate the lease and will be recognized when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

We have lease agreements with lease and non-lease components which we account for as a single lease component. Also, for certain equipment leases, we apply a portfolio approach to effectively account for the operating lease right-of-use assets and liabilities.

Finance lease and lessor accounting recognition has remained substantially unchanged under ASU 2016-02 and had no impact on the Company's balance sheet, results of operations, or cash flows as a result of the adoption of ASU 2016-02.

The Company has operating and finance leases for manufacturing facilities, corporate offices, sales offices, vehicles, and certain equipment. As of June 30, 2019, our leases had remaining lease terms of 1 to 13 years, some of which include options to extend the leases for up to 5 years, and some of which include options to terminate the leases within 1 year. As of June 30, 2019, the Company’s operating leases had a weighted average remaining lease term of 6 years and a weighted average discount rate of 4.9%. As of June 30, 2019, the Company’s finance leases had a weighted average remaining lease term of 1 year and a weighted average discount rate of 4.3%.

On April 30, 2019, the Company, its domestic subsidiaries, and certain of its Canadian and European subsidiaries (collectively, the “Borrowers”), entered into the Third Amended and Restated Credit Agreement (“Amended Credit Agreement”) with PNC Bank, N.A., Bank of America, N.A., Wells Fargo Bank, N.A., Citizens Bank, N.A., and BMO Harris Bank, N.A. This Amended Credit Agreement modifies the prior revolving credit facility which had a maximum credit line of $195,000 and extends the maturity date from March 13, 2020 to April 30, 2024. The Amended Credit Agreement provides for a five-year, revolving credit facility that permits aggregate borrowings of the Borrowers up to $140,000 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 Amended Credit Agreement’s incremental loan feature permits the Company to increase the available revolving borrowings under the facility by up to an additional $50,000 and provides for additional term loan borrowings of up to $25,000 subject to the Company’s receipt of increased commitments from existing or new lenders and the satisfaction of certain conditions.

The Company’s and the domestic, Canadian, and United Kingdom guarantors’ (the “Guarantors”) obligations under the Amended Credit Agreement are secured by the grant of a security interest by the Borrowers and Guarantors in substantially all of the personal property owned by such entities. Additionally, the equity interests in each of the loan parties, other than the Company, and the equity interests held by each loan party in their domestic subsidiaries, have been pledged to the lenders as collateral for the lending obligations.

Borrowings under the Amended Credit Agreement bear interest at rates based upon either the base rate or Euro-rate plus applicable margins. Applicable margins are dictated by the ratio of the Company’s total net indebtedness to the Company’s consolidated EBITDA for four trailing quarters, as defined in the Amended Credit Agreement. The base rate is the highest of (a) the Overnight Bank Funding Rate plus 50 basis points, (b) the Prime Rate, or (c) the Daily Euro-rate plus 100 basis points (each as defined in the Amended Credit Agreement). The base rate and Euro-rate spreads range from 25 to 125 basis points and 125 to 225 basis points, respectively.

The Amended Credit Agreement includes three financial covenants: (a) Maximum Gross Leverage Ratio, defined as the Company’s consolidated Indebtedness 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 Amended Credit Agreement, and (ii) 3.50 to 1.00 for all testing periods occurring during an Acquisition Period; (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 Amended Credit Agreement, which must be less than 1.25 to 1.00; and (c) Minimum Working Capital to Revolving Facility Usage Ratio, defined as the sum of the inventory and

accounts receivable of the Borrowers and certain other Guarantors divided by the Revolving Facility Usage, as defined in the Amended Credit Agreement, which must be less than 1.40 to 1.00.

The Amended Credit Agreement permits the Company to pay dividends and make distributions and redemptions with respect to its stock provided no event of default or potential default (as defined in the Amended Credit Agreement) has occurred prior to or after giving effect to the dividend, distribution, or redemption. Additionally, the Amended Credit Agreement permits the Company to complete acquisitions so long as (a) no event of default or potential default has occurred prior to or as a result of such acquisition; (b) the liquidity of the Borrowers is not less than $25,000 prior to giving effect to such acquisition; and (c) the aggregate consideration for the acquisition does not exceed: (i) $50,000 per acquisition; (ii) $50,000 in the aggregate for multiple acquisitions entered into during four consecutive quarters; and (iii) $100,000 in the aggregate over the term of the Amended Credit Agreement.

Other restrictions exist at all times including, but not limited to, limitations on the Company’s sale of assets and the incurrence by either the Borrowers or the non-borrower subsidiaries of the Company of other indebtedness, guarantees, and liens.

As of June 30, 2019, L.B. Foster was in compliance with the Amended Credit Agreement’s covenants.

As of June 30, 2019, the Company had outstanding letters of credit of approximately $836 and had net available borrowing capacity of $73,841. The maturity date of the facility is April 30, 2024.

On April 29, 2019, the credit facility with NatWest Bank for the Company's United Kingdom operations was terminated.

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.

Cash equivalents - Included within “Cash and cash equivalents” are investments in non-domestic term deposits. The carrying amounts approximate fair value because of the short maturity of the instruments.

LIBOR-based interest rate swaps - To reduce the impact of interest rate changes on outstanding variable-rate debt, the Company entered into forward starting LIBOR-based interest rate swaps with notional values totaling $50,000. The fair value of the interest rate swaps is 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, 2019, the interest rate swaps were recorded within “Other accrued liabilities.”

The interest rate swaps 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 of 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, 2019 and 2018, we recognized interest income of $56 and $1, respectively, and for the six months ended June 30, 2019 and 2018, we recognized interest income of $121 and interest expense of $34, respectively, from interest rate swaps.

In accordance with the provisions of ASC 820, “Fair Value Measurement,” the Company measures certain nonfinancial assets and liabilities at fair value, which are recognized or disclosed on a nonrecurring basis.

Share-based Compensation [Abstract]

Stock-based Compensation

Stock-based Compensation

The Company applies the provisions of ASC 718, “Compensation – Stock Compensation,” to account for the Company’s stock-based compensation. Stock-based compensation cost is measured at the grant date based on the calculated fair value of the award and is recognized over the employees’ requisite service periods. The Company recorded stock compensation expense related to restricted stock awards and performance share units of $1,179 and $822 for the three months ended June 30, 2019 and 2018, respectively, and $2,034 and $1,904 for the six months ended June 30, 2019 and 2018, respectively. As of June 30, 2019, unrecognized compensation expense for unvested awards approximated $6,293. The Company will recognize this expense over the upcoming 3.8 years through April 2023.

Shares issued as a result of vested stock-based compensation awards generally will be from previously issued shares that have been reacquired by the Company and held as treasury stock or authorized and previously unissued common stock.

Restricted Stock Awards and Performance Share Units

Under the 2006 Omnibus Plan, the Company grants eligible employees restricted stock and performance 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 agreement. Since May 2018, awards of restricted stock are subject to a minimum one-year vesting period, including those granted to non-employee directors. Prior to May 2018, awards to non-employee directors were made in fully-vested shares. Performance share units are offered annually under separate three-year long-term incentive programs. Performance share units are subject to forfeiture and will be converted into common stock of the Company based upon the Company’s performance relative to performance measures and conversion multiples, as defined in the underlying program. If the Company’s estimate of the number of performance share units expected to vest changes in a subsequent accounting period, cumulative compensation expense could increase or decrease. The change will be recognized in the current period for the vested shares and would change future expense over the remaining vesting period.

Since May 1, 2017, non-employee directors have been permitted to defer receipt of annual stock awards and equity elected to be received in lieu of quarterly cash compensation. If so elected, these deferred stock units will be issued as common stock six months

after separation from their service on the Board of Directors. Since May 2018, there have been no non-employee directors who elected the option to receive deferred stock units of the Company’s common stock in lieu of director cash compensation.

In February 2019, the Compensation Committee approved the 2019 Performance Share Unit Program and the Executive Annual Incentive Compensation Plan (consisting of cash and equity components). The Compensation Committee also certified the actual Company performance achievement in the 2016 Performance Share Unit Program, which actual performance resulted in no payout relative to the 2016 Performance Share Unit Program target performance metrics.

The following table summarizes the restricted stock awards, deferred stock units, and performance share units activity for the six months ended June 30, 2019:

	Restricted Stock	Deferred Stock Units	Performance Share Units	Weighted Average Grant Date Fair Value

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 (“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 two defined contribution plans for its employees in Canada, as well as one post-retirement benefit plan. The Company also maintains two defined contribution plans and one defined benefit plan for its employees in the United Kingdom.

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 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 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. 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 payments under the UPRR Settlement Agreement for the remainder of the year ending December 31, 2019 and thereafter are as follows:

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. The Company and a predecessor owned and operated a facility near the harbor site for a period prior to 1982. By letter dated March 16, 2018, the EPA informed the Company of the proposed schedule for consent decree negotiations to implement the Portland Harbor Superfund Site Record of Decision, with negotiations scheduled to commence by the end of 2019, and the EPA also set a proposed deadline of June 2019 to conclude negotiations with PRPs for the performance of remedial design work in the harbor. 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. 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, a private allocation process among numerous PRPs in a working group is ongoing. We cannot predict the ultimate impact of these proceedings because of the large number of PRPs involved throughout the harbor 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, 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 of June 30, 2019 and December 31, 2018, the Company maintained environmental reserves approximating $6,078 and $6,128, respectively. The following table sets forth the Company’s environmental obligation:

	Environmental liability
Balance as of December 31, 2018	$	6,128
Additions to environmental obligations	3
Environmental obligations utilized	(53)
Balance as of June 30, 2019	$	6,078

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, 2019.

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, 2019, no such disclosures were considered necessary.

The Company's effective tax rate for the three and six months ended June 30, 2019 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 continued 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 and the mix of income across jurisdictions could also impact the effective income tax rate.

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 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all estimates and adjustments (consisting of normal recurring accruals, unless otherwise stated herein) considered necessary for a fair presentation of the financial position of L.B. Foster Company and subsidiaries as of June 30, 2019 and December 31, 2018, its Condensed Consolidated Statements of Operations and its Condensed Consolidated Statements of Stockholders' Equity for the three and six months ended June 30, 2019 and 2018, and its Condensed Consolidated Statements of Cash Flows for the six months ended June 30, 2019 and 2018, have been included. However, actual results could differ from those estimates. The results of operations for interim periods are not necessarily indicative of the results that may be expected for the year ending December 31, 2019. The Condensed Consolidated Balance Sheet as of December 31, 2018 was derived from audited financial statements. This Quarterly Report on Form 10-Q should be read in conjunction with the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018. 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.

Recently issued accounting standards

Recently Issued Accounting Standards

In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. (“ASU”) 2018-15, “Intangibles - Goodwill and Other - Internal-Use Software” (“ASU 2018-15”). The ASU requires capitalization of certain implementation costs incurred in a cloud computing arrangement that qualifies as a service contract. The amendments in the ASU are effective for fiscal years beginning after December 15, 2019 and for interim periods therein with early adoption permitted. The Company is currently evaluating the potential impact of the ASU on its consolidated financial statements.

Recently Adopted Accounting Standards

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). The new accounting requirements include the accounting for, presentation of, and classification of leases. The guidance resulted in most leases being capitalized as a right-of-use asset with a related balance sheet liability. The requirements of the new standard are effective for annual reporting periods beginning after December 15, 2018, and interim periods within those annual periods. The Company adopted the provisions of ASU 2016-02 on January 1, 2019, using the modified retrospective approach as of the beginning of the period of adoption. Additionally, the Company has elected to apply the practical expedient package for leases that commenced prior to the effective date, not to apply the recognition requirements in the standard to short-term leases, and not to separate non-lease components from lease components. The Company has presented the disclosures required by ASU 2016-02 in Note 8.

In February 2018, the FASB issued ASU 2018-02, “Income Statement – Reporting Comprehensive Income; Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income” (“ASU 2018-02”), which allows companies to reclassify stranded tax effects caused by the US Tax Cuts and Jobs Act (the “Tax Act”) from accumulated other comprehensive income to retained earnings. The amendments eliminate the stranded tax effects resulting from the Tax Act and improve the usefulness of information reported to financial statement users. However, because the amendments only relate to the reclassification of the income tax effects of the Tax Act, the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from continuing operations is not affected. The Company adopted ASU 2018-02 during the first quarter of 2019 and has chosen to record the reclassification as of the beginning of the period of adoption. As a result of adopting this standard, we reclassified stranded tax effects of $633 from Accumulated other comprehensive loss to Retained earnings.

The SEC Disclosure Update and Simplification release announces the SEC's adoption of certain amendments in August 2018. While most of the amendments eliminate outdated or duplicative disclosure requirements, the final rule amends the interim financial statement requirements to require a reconciliation of changes in stockholders’ equity in the notes to the financial statements or as a separate statement. This analysis should reconcile the beginning balance to the ending balance of each caption in stockholders’ equity for each period for which an income statement is required to be filed and comply with the remaining content requirements of Rule 3-04 of Regulation S-X. As a result, registrants are required to provide the reconciliation for both the comparable quarterly and year-to-date periods in their Quarterly Reports on Form 10-Q but only for the year-to-date periods in registration statements, beginning in the first quarter of 2019. The Company has included the reconciliation of changes in stockholders’ equity as a separate statement.

Inventory

Inventories of the Company are valued at average cost or net realizable value, whichever is lower.

Share based compensation

The Company applies the provisions of ASC 718, “Compensation – Stock Compensation,” to account for the Company’s stock-based compensation. Stock-based compensation cost is measured at the grant date based on the calculated fair value of the award and is recognized over the employees’ requisite service periods
