L.B. Foster Company (FSTR) Income Statement

The revenue line shows no clean trajectory: 2025Q4 revenue of $160.4 million and 2026Q1's 23.9% year-over-year gain followed a 21.3% contraction in 2025Q1, and 2026Q2 reversed back into decline. That volatility appears consistent with railroad and energy-related project cycles rather than sustained end-market share gains, so investors should treat sequential quarters as noisy rather than as trend. The fact that 2026Q2 revenue of $138.6 million roughly matches 2025Q2's $143.6 million suggests the business is tracking volume normalization, not a new growth regime.

Gross margin discipline appears reasonable — 22.3% in 2026Q2 compares favorably with Kaiser Aluminum's 9.5% and is broadly in line with Olympic Steel's 23.2%, suggesting the company is not competing purely on price against larger metals distributors. However, the spread between gross and operating margin has compressed to as little as 3.4 percentage points in 2025Q1, indicating that gross margin resilience alone does not protect profitability when volumes fall. The stability of gross margin through a 21.3% revenue decline suggests pricing or mix held up better than volumes did.

SG&A consumed 21.5% of revenue in 2025Q1 versus 17.4% in 2026Q2, a ratio that moved materially without any corresponding change in gross margin structure, implying the cost base is largely fixed relative to near-term volume. This is the key reason operating income swung from negative $1.9 million to positive $8.3 million within three quarters on a revenue recovery that was not proportionally larger. Operating leverage therefore appears asymmetric: favorable in rebound quarters such as 2025Q4, when SG&A fell slightly to $23.1 million on $160.4 million of revenue, but punitive in downturns.

The 2025Q1 loss is the single most informative period in the series because it revealed the business's breakeven threshold — gross profit of $20.2 million was insufficient to cover $21.0 million of SG&A, implying the company needs roughly $110 million or more of quarterly revenue to sustain positive operating income at current cost levels. The recovery through 2025Q3 and 2025Q4 looks mechanical rather than structural, since gross margin barely improved (20.6% to 22.5%) while SG&A stayed flat, suggesting no meaningful overhead reset occurred. That leaves operating leverage as the lasting legacy of the trough, and it warrants monitoring if 2026 volumes soften further.
