L.B. FOSTER REPORTS FIRST QUARTER OPERATING RESULTS

PITTSBURGH, PA, May 2, 2011 – 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 2011 first quarter operating results, including the following items:

·   First quarter sales increased by $35.1 million or 42.8% due to a strong sales quarter by Portec Rail Products Inc., as well as a 14.4% sales increase in the legacy L.B. Foster business.

·   Gross Profit margin was 14.9%, 20 basis points better than the prior year.

o   The Portec Rail Products business contributed a gross margin of 21.7% which, as expected, included charges from purchase accounting related asset step-ups.

o   The legacy Foster margins were lower than the prior year due to a weak first quarter in our precast buildings division, as well as unabsorbed plant costs at our Grand Island, NE concrete tie facility as a limited amount of production was concluded in the first quarter and we began dismantling the equipment.

·   Selling and administrative expense increased $6.5 million, principally due to the inclusion of the Portec Rail Products results.

·   First quarter net income was $0.7 million or $0.07 per diluted share compared to $1.8 million or $0.17 per diluted share last year.  Factors negatively impacting net income for this quarter were:

o   The recognition of expense related to the sale of Portec inventory that was written up to fair market value as of the acquisition date resulting in increased cost of goods sold of $2.5 million ($0.17 per diluted share).

o   Acquisition related amortization and depreciation of definitive-lived intangible and tangible assets stepped up to market value of $0.8 million ($0.06 per diluted share).

o   LIFO adjustments were $0.4 million ($0.03 per diluted share) unfavorable compared to the prior year.

·   Adjusted EBITDA was $6.5 million compared to $5.0 million in the prior year quarter.

·   First quarter bookings were $163.8 million compared to $106.1 million last year, an increase of 54.4%.  Excluding Portec, bookings were 27.3% higher than last year.  At quarter end, our backlog was $237.1 million, 15.8% higher than the prior year (4.9% without Portec).

Stan L. Hasselbusch, L. B. Foster’s president and chief executive officer, said, “Our performance in the first quarter, which is traditionally our weakest quarter due to seasonality, was negatively impacted by expenses related to the acquisition of Portec Rail Products, Inc. and to our Grand Island facility.  The most significant of these costs, a $2.5 million charge to gross profit, is a non-recurring expense that relates to the requirement to write-up inventory purchased in an acquisition to net realizable value, which takes most of the margin away when it is sold.  This negative adjustment has been completely flushed through our results in the first quarter and will not impact us the rest of the year.”   Mr. Hasselbusch went on to say, “Our margins were not where we wanted them as they were negatively impacted by the Grand Island shut down, a weak precast buildings performance and a disadvantageous sales mix as distribution sales increased by 25% while distribution margins declined by 120 basis points. With regard to the Portec acquisition, we have moved past an intense 120 day integration period and are planning to continue these efforts for the remainder of the year.  We continue to see many promising opportunities in the friction management and Salient product lines and are excited about the long term prospects for these businesses.”  Mr. Hasselbusch concluded by adding, “As we move through 2011, we expect to continue to experience a highly competitive market environment and we also anticipate significantly extended delays before a new transportation bill is passed, but we are optimistic that the overall economy is improving.  Our bookings and backlog are very strong and we expect this strength to be reflected in our results for the remainder of this year.”

Foster Company will conduct a conference call and webcast to discuss its first quarter 2011 operating results and general market activity and business conditions on Monday, May 2, 2011 at 11:00am ET.  The call will be hosted by Mr. Stan Hasselbusch, President and Chief Executive Officer.  Listen via audio on the L.B.

L.B. Foster Company

Reconciliation of GAAP to Non-GAAP Financial Measures

L.B. Foster (Foster) reports its financial results in accordance with generally accepted accounting principles (GAAP).  However, Foster believes that certain non-GAAP financial measures are useful in managing our performance.  One such non-GAAP measure is Adjusted EBITDA.

Adjusted EBITDA, which Foster defines as net income before interest, taxes, depreciation, amortization and other non-cash charges (principally related to purchase accounting adjustments, such as the $2.5 million charge taken in the first quarter of 2011 related to the write-up of inventory owned by Portec  to fair value less cost to sell on the date of acquisition) is used due to its wide acceptance as a measure of operating profitability before non-operating expenses (interest and taxes) and noncash charges (depreciation and amortization and other noncash charges).  Additionally, Adjusted EBITDA is one of the performance measures used in Foster’s debt covenant calculations and incentive compensation plan.

This non-GAAP financial measure is not a substitute for GAAP financial results and should only be considered in conjunction with Foster’s financial information that is presented in accordance with GAAP. A quantitative reconciliation of GAAP net income to Adjusted EBITDA is provided in the table below.
