L.B. FOSTER REPORTS FIRST QUARTER OPERATING RESULTS

PITTSBURGH, PA, May 3, 2016 – 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 financial results for its first quarter ended March 31, 2016.

First Quarter Highlights

Consolidated Results

First quarter net sales of $126.3 million decreased by $11.6 million, or 8.4%, compared to the prior year quarter due to a 17.2% decrease in Rail Products and Services (“Rail”) segment sales and a 7.0% decline in Construction segment sales, partially offset by a 16.2% increase in Tubular and Energy Services (“Tubular”) segment sales.

Gross profit margin of 19.0% compared to 22.2% in the prior year quarter, a decrease of 326 basis points. The decrease was driven by lower margins across each of the segments with the most significant reduction coming from the Tubular segment.

First quarter net loss of $2.8 million, or $(0.28) per diluted share, compared to net income of $4.3 million, or $0.41 per diluted share, in the prior year quarter.

First quarter bookings were $118.0 million, a 27.8% decrease from the prior year quarter, due to 40.8%, 13.2% and 9.3% declines in Rail, Tubular and Construction segment orders, respectively.

Cash flow from operating activities for the first quarter of 2016 used $5.1 million of cash compared to $7.4 million of cash used in the first quarter of 2015.

Robert P. Bauer, L.B. Foster Company’s President and Chief Executive Officer, commented, “The weakness that we experienced in the first quarter was driven by the ongoing challenges we face in many of the markets we serve, in addition to the headwinds driven by the current commodity cycle. While the first quarter is traditionally our seasonally weakest quarter, the year got off to a particularly slow start, driven by reduced spending in the North American freight rail market and softer than expected spend on highway and other civil construction projects. Profitability in the quarter was impacted by de-leverage on lower volume which also put pressure on gross margins.”

Mr. Bauer continued, “As part of our plan to achieve our targets, today we announced a new restructuring initiative aimed at improving profitability. While we have taken steps since the beginning of last year to rationalize our expense structure to adjust to lower volumes, ongoing market conditions have caused us to further scrutinize our expense structure throughout the organization to drive greater efficiencies. We plan to defer expenses that are not related to either cost reductions or securing new business. We are confident that these additional steps will better position L.B. Foster to deliver solid results when demand improves.”

Business Segment Results

($ in thousands)

Rail Products and Services Segment

Rail sales decreased 17.2% in the quarter due to lower sales across all significant rail divisions, with the exception of transit products, as a result of reduced volumes. Reduced sales to Union Pacific Railroad accounted for more than half of the decline. Gross profit margin was negatively impacted by reduced sales volumes, partially offset by manufacturing efficiencies and cost reductions.

Construction Products Segment

Construction sales decreased 7.0% in the quarter due to lower sales across our product lines. Gross profit margin was negatively impacted by a decline in margins for precast concrete products, partially offset by improved margins in fabricated bridge products.

Tubular and Energy Services Segment

Tubular sales improved by 16.2% in the quarter due to sales from coated products, precision measurement systems and sales from test and inspection services, which was acquired in March 2015. Tubular gross profit margins declined principally due to lower margins in our test and inspection services business, partially offset by improved margins in coated products.
