Q4 2024 net sales fell 5.0% to $128.183M while gross margin expanded 100 bps to 22.3%; adjusted EBITDA rose 18.7% to $7.238M, driven by lower SG&A and stronger Rail profitability .

Management introduced FY 2025 guidance: net sales $540–$580M, adjusted EBITDA $42–$48M, FCF $20–$30M, capex ~2% of sales; backlog started 2025 down 13% in less profitable lines, implying a softer H1 but stronger profitability mix; midpoints imply ~5.5% organic sales growth and ~34% adjusted EBITDA growth YoY .
Board authorized a new 3‑year $40M share repurchase program, replacing the prior $15M plan; total debt fell to $46.9M and gross leverage dropped to 1.2x at year-end, supported by strong Q4 operating cash flow of $24.3M .

What Went Well and What Went Wrong

What Went Well

Rail segment delivered double-digit growth: net sales +14.2% to $79.154M and gross margin +300 bps to 22.2%, with strength in Global Friction Management and Technology Services & Solutions and UK recovery .
SG&A fell $2.842M (-10.4%) YoY to $24.421M, benefiting from restructuring and lower bad debt; adjusted EBITDA increased 18.7% to $7.238M despite lower sales .
“We finished 2024 with strong cash generation and improving profitability…Share repurchases during 2024 totaled 300,302 shares…execution of our strategic playbook is translating into a structural improvement” — CEO John Kasel .

What Went Wrong

Infrastructure Solutions net sales declined 25.2% to $49.029M; gross margin fell 90 bps to 22.6%, driven by soft pipeline coating volumes and exit of bridge grid deck product line .
Backlog declined 13.0% YoY to $185.909M, reflecting softer Rail Products demand and scaled-back UK initiatives; book-to-bill trailed at 0.95:1.00 .
Management expects the start of 2025 to be softer versus an “exceptionally strong” Q1 2024 given lower backlog and macro volatility; tariff risk and choppy conditions cited as headwinds needing supply-chain flexibility .

Free cash flow swing factors: Working capital seasonality (Q2–Q3 builds), UP settlement completed; expect strong year-end cash and buybacks .
Tariffs impact: Prior experience (Section 232) and strong domestic mill relationships mitigate risk; ability to pass through pricing .
Restructuring benefits: ~$2M savings realized in 2024; run-rate ~$4.5M, adding ~$2.5M incremental in 2025; minimal 2025 P&L charges expected .

Key Takeaways for Investors

Margin resiliency: Despite a 5% sales decline, gross margin expanded 100 bps and adjusted EBITDA grew 18.7%—evidence of mix shift toward Rail Technologies and disciplined SG&A .
Rail growth engines: TTM/WILD and friction management are scaling, supported by safety/regulatory focus; expect continued margin mix benefit into 2025 .
Infrastructure pivot: Protective Coatings is exiting a multi-year trough with Q4 orders up sharply; Precast backlog and Florida/Tennessee capacity position Infrastructure for recovery .
Balance sheet strength: Q4 operating cash $24.3M; total debt cut to $46.9M; gross leverage at 1.2x provides flexibility for buybacks and tuck-ins .
Capital returns: New $40M buyback authorization is a clear catalyst; management views valuation attractive and intends balanced execution at leverage ~1x–2x .
FY 2025 setup: Backlog down in lower-margin lines implies softer H1 but improved profitability mix; guidance midpoints target ~34% adjusted EBITDA growth on ~5.5% organic sales growth—watch execution in Rail Tech and Precast .
Risk monitors: Tariff developments, macro choppiness, and UK demand remain watch items; management cites supply-chain flexibility and pricing mechanisms to mitigate shocks .
