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 1.7% compounded annual growth rate over the last five years. This fell short of our benchmarks and is a poor baseline for our analysis.

We at StockStory place the most emphasis on long-term growth, but within industrials, a half-decade historical view may miss cycles, industry trends, or a company capitalizing on catalysts such as a new contract win or a successful product line. 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 $189.3 million in the latest quarter and averaged 4.4% year-on-year growth over the last two years. Because this number is better than its revenue growth, we can see the company accumulated more orders than it could fulfill and deferred revenue to the future. This could imply elevated demand for L.B. Foster’s products and services but raises concerns about capacity constraints.

This quarter, L.B. Foster reported robust year-on-year revenue growth of 25.1%, and its $160.4 million of revenue topped Wall Street estimates by 1%.

Looking ahead, sell-side analysts expect revenue to grow 2.9% over the next 12 months. While this projection suggests its newer products and services will spur better top-line performance, it is still below the sector average.

Operating Margin

Operating margin is an important measure of profitability as it shows the portion of revenue left after accounting for all core expenses – everything from the cost of goods sold to advertising and wages. It’s also useful for comparing profitability across companies with different levels of debt and tax rates because it excludes interest and taxes.

L.B. Foster was profitable over the last five years but held back by its large cost base. Its average operating margin of 2.3% 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 3.4 percentage points over the last five years, as its sales growth gave it operating leverage.

In Q4, L.B. Foster generated an operating margin profit margin of 4.9%, up 2.1 percentage points year on year. The increase was encouraging, and because its gross margin actually decreased, we can assume it was more efficient because its operating expenses like marketing, R&D, and administrative overhead grew slower than its revenue.

Earnings Per Share

We track the long-term change in earnings per share (EPS) for the same reason as long-term revenue growth. Compared to revenue, however, EPS highlights whether a company’s growth is profitable.

L.B. Foster’s flat EPS over the last five years was below its 1.7% annualized revenue growth. However, its operating margin actually improved during this time, telling us that non-fundamental factors such as interest expenses and taxes affected its ultimate earnings.

Like with revenue, we analyze EPS over a shorter period to see if we are missing a change in the business.

L.B. Foster’s two-year annual EPS growth of 130% was fantastic and topped its flat revenue.

We can take a deeper look into L.B. Foster’s earnings quality to better understand the drivers of its performance. L.B. Foster’s operating margin has expanded over the last two 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.

In Q4, L.B. Foster reported EPS of $0.22, up from negative $0.02 in the same quarter last year. Despite growing year on year, this print missed analysts’ estimates. Over the next 12 months, Wall Street expects L.B. Foster’s full-year EPS of $0.69 to grow 158%.

Key Takeaways from L.B. Foster’s Q4 Results

It was good to see L.B. Foster provide full-year revenue guidance that slightly beat analysts’ expectations. We were also happy its revenue narrowly outperformed Wall Street’s estimates. On the other hand, its EBITDA missed and its EPS fell short of Wall Street’s estimates. Overall, this quarter could have been better. The stock traded up 1.7% to $32.82 immediately after reporting.
