Construction Partners, a US civil infrastructure company, stands out as a strong long-term industrials investment, whilst Insteel and Enphase underwhelm, according to recent analysis. Construction Partners has demonstrated exceptional performance with 39.9% annual revenue growth over two years and earnings per share increasing 46.7% annually. Its free cash flow margin expanded by 7.4 percentage points over five years, indicating improved capital efficiency. In contrast, Insteel's annual revenue growth of 5.9% over five years falls short of sector standards. Its free cash flow margin contracted by 5 percentage points, suggesting increased capital consumption. Enphase faces headwinds with sales declining 12.5% annually over two years, whilst its free cash flow margin dropped 10.9 percentage points, reflecting heightened defensive investments amid market pressures.

The 2025-2026 tariff regime, including a 10% baseline on most imports and reciprocal tariffs on China reaching 145%, has fundamentally altered competitive dynamics in consumer goods. Companies with domestic supply chains are gaining structural advantages. Insteel Industries, America's largest manufacturer of steel wire reinforcing products, is benefiting from Section 232 tariffs on derivative products, which have caused imports to decline sharply. The company operates almost entirely domestically, with only 10% of revenue exposed to imports, positioning it well for infrastructure investment tailwinds. Duluth Trading Co. reported gross margin expansion of 890 basis points in Q4 whilst absorbing over $7 million in tariff costs. The company's direct-to-factory sourcing initiative has reduced per-unit costs by eliminating middlemen.

Insteel Industries reported second-quarter net earnings of $5.2 million, or $0.27 per diluted share, down from $10.2 million, or $0.52 per share, in the prior year period. The decline was attributed to severe winter weather disruptions, lower spreads and higher conversion costs. Shipments fell 5.9% year-over-year but rose 6.9% sequentially from the first quarter. CEO H.O. Woltz III said prolonged winter weather across most markets reduced construction activity and delayed projects, though he maintained the underlying business upturn remains intact. Average selling prices increased 14.2% year-over-year, driven by pricing actions to offset raw material costs and tariffs. Steel wire rod prices rose $90 per tonne during the quarter. The company said April shipments are trending above forecasted levels.
