John Kasel, President and Chief Executive Officer, commented, "We carried the favorable momentum generated at the end of 2025 into our first quarter, posting strong growth and profitability expansion across the business. Both segments delivered exceptional results in the quarter, led by Rail sales growth of 38.4%, reflecting a strong recovery in domestic Rail demand compared to last year's weaker start to the year. Sales volumes were higher across all Rail business units, with Rail Products and Friction Management up 40.8% and 39.5%, respectively. Technology Services and Solutions ("TS&S") sales were also up 29.1% on increased short-term project work in the United Kingdom ("UK").
Company Overview
Founded with a $2,500 loan, L.B. Foster (NASDAQ: FSTR) is a provider of products and services for the transportation and energy infrastructure sectors, including rail products, construction materials, and coating solutions.
Revenue Growth
A company’s long-term performance is an indicator of its overall quality. Any business can have short-term success, but a top-tier one grows for years. Regrettably, L.B. Foster’s sales grew at a sluggish 2.8% compounded annual growth rate over the last five years. This fell short of our benchmarks and is a poor baseline for our analysis.
Long-term growth is the most important, but within industrials, a half-decade historical view may miss new industry trends or demand cycles. L.B. Foster’s recent performance shows its demand has slowed as its revenue was flat over the last two years. 
L.B. Foster also reports its backlog, or the value of its outstanding orders that have not yet been executed or delivered. L.B. Foster’s backlog reached $209.6 million in the latest quarter and averaged 1.7% year-on-year growth over the last two years. Because this number is in line with its revenue growth, we can see the company effectively balanced its new order intake and fulfillment processes. 
This quarter, L.B. Foster reported robust year-on-year revenue growth of 23.9%, and its $121.1 million of revenue topped Wall Street estimates by 16.2%.
Looking ahead, sell-side analysts expect revenue to grow 2.3% over the next 12 months, similar to its two-year rate. Although this projection suggests its newer products and services will catalyze better top-line performance, it is still below average for the sector.

Operating Margin
Operating margin is a key measure of profitability. Think of it as net income - the bottom line - excluding the impact of taxes and interest on debt, which are less connected to business fundamentals.
L.B. Foster was profitable over the last five years but held back by its large cost base. Its average operating margin of 2.5% was weak for an industrials business. This result isn’t too surprising given its low gross margin as a starting point.
On the plus side, L.B. Foster’s operating margin rose by 4.6 percentage points over the last five years, as its sales growth gave it operating leverage.
This quarter, L.B. Foster generated an operating margin profit margin of 1.7%, up 3.7 percentage points year on year. The increase was encouraging, and because its operating margin rose more than its gross margin, we can infer it was more efficient with expenses such as marketing, R&D, and administrative overhead.
Earnings Per Share
Revenue trends explain a company’s historical growth, but the long-term change in earnings per share (EPS) points to the profitability of that growth – for example, a company could inflate its sales through excessive spending on advertising and promotions.
L.B. Foster’s EPS grew at 6% compounded annual growth rate over the last five years. On the bright side, this performance was better than its 2.8% annualized revenue growth and tells us the company became more profitable on a per-share basis as it expanded.
Diving into the nuances of L.B. Foster’s earnings can give us a better understanding of its performance. As we mentioned earlier, L.B. Foster’s operating margin expanded by 4.6 percentage points over the last five years. This was the most relevant factor (aside from the revenue impact) behind its higher earnings; interest expenses and taxes can also affect EPS but don’t tell us as much about a company’s fundamentals.
Like with revenue, we analyze EPS over a shorter period to see if we are missing a change in the business.
For L.B. Foster, its two-year annual EPS growth of 18.8% was higher than its five-year trend. This acceleration made it one of the faster-growing industrials companies in recent history.
In Q1, L.B. Foster reported EPS of $0.14, up from negative $0.20 in the same quarter last year. This print easily cleared analysts’ estimates, and shareholders should be content with the results. Over the next 12 months, Wall Street expects L.B. Foster’s full-year EPS of $1.03 to grow 51.5%.
Key Takeaways from L.B. Foster’s Q1 Results
