L.B. FOSTER REPORTS SECOND QUARTER OPERATING RESULTS

PITTSBURGH, PA, August 4, 2015 – L.B. Foster Company (NASDAQ: FSTR), a leading manufacturer, fabricator, and distributor of products and services for rail, construction, energy and utility markets, today reported its second quarter 2015 operating results, including:

Second Quarter Results

CEO Comments

Robert P. Bauer, L.B. Foster Company’s President and Chief Executive Officer, commented, “Our results for the quarter reflect the significant acquisition activity the company has engaged in during the fourth quarter of 2014 and first quarter of 2015, including the impact from interest, amortization, transaction and integration costs associated with recently closing three significant acquisitions. In addition, our legacy businesses delivered mixed results with some meeting or exceeding our expectations and others being affected by market weakness and pressure on steel prices. The acquisitions serving the energy markets were not accretive to EPS in the quarter, and we are not forecasting any improvement for the balance of 2015. This is having a dilutive impact on our earnings and will likely continue at the forecasted operating levels for the next two quarters. Despite the difficult environment, both IOS and Chemtec Energy Services continue to be well positioned to serve customers with exploration, production and midstream applications requiring tubular services and critical measurement systems.

Our construction and tubular businesses reported sales increases in both the quarter and on a year-to-date basis. Our Piling and Precast Building divisions, including Carr concrete products, have been the driving force behind a 21% year-over-year increase in sales for the Construction segment through six months. Tubular and Energy Services sales increases were driven by the acquisitions and our base Coated Products business is expected to have a solid second half as our production interruptions from the factory upgrades will be behind us.

Sales for the Rail segment are down for the first half as they cope with fewer projects in the Transit market, pockets of weakness in freight rail, a weaker European business with unfavorable currency impact, and declining sales from Union Pacific Railroad. As previously mentioned; the Company is making adjustments as we remove all Union Pacific sales from our forecasts and have taken charges in the quarter to reflect current conditions. We are also incurring litigation costs for the warranty dispute which are discussed later in the press release.”

Mr. Bauer concluded by saying, “Finally, I remain encouraged by our efforts to drive gross margin improvements. Consolidated gross margins improved in the quarter and in the first half over prior year as we reached 21.9% on a year-to-date basis. As we make investments in systems and continuous improvement programs, we are focused on driving greater efficiency across the Company.”

Q2 Business Segment Highlights

($000’s)

Rail Products and Services Segment

Rail sales decreased 19.2% due to lower sales volumes from several of our track and track component businesses as well as weakness in steel prices, reduced sales to the Union Pacific Railroad and unfavorable currency fluctuations. Despite the reduced volumes in 2015, the current quarter gross profit margin improved by 160 bps over the prior, after excluding the impact of the current year ($0.4

million) and prior year ($4.6 million) warranty related charges, due to improved margins in several product categories as well as an improved product mix.

Construction Products Segment

Construction sales increased by 18.4% in the quarter due principally to stronger sales of our precast buildings as well as sales contributed by our Carr Concrete Products acquisition. Gross profit margins improved due to increased margins in our Piling Products and Precast Buildings divisions.

Tubular and Energy Services Segment

Tubular sales improved by 99.7% in the quarter due to sales of our fourth quarter 2014 acquisition of Chemtec Energy Services and first quarter acquisition of Inspection Oilfield Services, partially offset by softer Coated Products sales. Tubular gross profit margins declined due principally to lower Coated Products margins as well as sales mix due to the additional offerings from acquired businesses.

First Half 2015 Results

UNION PACIFIC CONCRETE TIE LITIGATION

The Company has responded to the claims in the lawsuit filed by Union Pacific Railroad related to the warranty dispute over concrete ties produced in our former Grand Island, NE facility. While we continue efforts to resolve the dispute, the litigation process is underway. L.B. Foster has responded to the claims, including by asserting defenses and counterclaims and anticipates seeking to amend its response to include additional defenses and counterclaims based on subsequent conduct by Union Pacific. Among other matters, L.B. Foster maintains that Union Pacific has submitted warranty claims, and has received in response, various replacement ties to which it is not entitled. No pretrial or trial schedule has yet been set in the lawsuit.

L.B. Foster provided replacement concrete ties through the first two quarters of 2015 in excess of the amount rated as warranty eligible pursuant to our agreement with the Union Pacific. L.B. Foster maintains a warranty reserve for concrete railroad ties that stands at approximately $7.8 million as of June 30, 2015.

2015 Outlook

The Company expects 2015 sales to be in the range of $685 million to $725 million. Pretax income is expected to range between $34 million to $40 million while diluted EPS is expected to range from $2.15 to $2.50. We forecast EBITDA to be in the range of $65 to $71 million for the year.

There have been a number of factors impacting this decrease in guidance from last quarter, the most significant of which is the decline in our near term expectations for our recently acquired energy acquisitions. Additionally, we have seen a softening in demand in certain sectors of our legacy rail business as well as our Piling Products division. This includes removing all Union Pacific Railroad sales from our forecast. We also have included increased anticipated litigation related costs concerning the defense and handling of the Union Pacific lawsuit.

Despite recent weakness, we continue to be bullish on the long-term prospects for growth and profitability of our energy acquisitions. We also believe that there are many opportunities in the global rail market that will afford us avenues for growth and value creation without Union Pacific Railroad sales in our mix of business.
