Business Overview

  • Noteworthy fact: Dual independent auditor reports included from PricewaterhouseCoopers LLP and KPMG LLP for fiscal year-end 2025 consolidated financial statements

Risk Factors

  • Tariff risk from U.S. administration on imports from Asia, with potential impact growing as low-tariff inventory depletes in subsequent quarters
  • Significant exposure to foreign currency fluctuations in Canadian dollar and Mexican peso against USD; impact immaterial in 2025 despite USD strengthening
  • Supply chain vulnerability due to lengthy import routes and shipping cost fluctuations affecting product gross profit
  • Commodity steel price increases in 2025, exposure delayed due to long supply chain but affects steel fasteners market segment
  • Floating interest rate exposure on Credit Facility debt; 1% rate hike would increase interest expense by $0.4 million
