Strategy
Management is focused on expanding its aftermarket hard parts business in North America while building a stronger position in test solutions and diagnostic equipment. It is also investing in manufacturing, remanufacturing and distribution capacity to support multiple product lines, improve service levels and enable future direct-shipment programs.
This is a higher-growth adjacency tied to EV development, charging systems and aerospace electrification.
The core business depends on scale, catalog coverage and service levels in a competitive replacement market.
Additional warehousing and remanufacturing capacity supports growth, inventory realignment and direct shipment programs.
Geography
The business is overwhelmingly North America-focused, with management stating that about 98% of fiscal 2025 product sales were in North America and about 2% in Asian and European countries. Operations include a major distribution center in Tijuana, Mexico, remanufacturing and core-sorting facilities, and a new warehousing/distribution site in Malaysia to support future direct shipment programs.
Risks
The company is highly exposed to customer concentration, with a few large accounts representing most sales, so pricing pressure or lost shelf space can quickly hurt revenue and margins. It also depends on foreign suppliers and imported components, making it vulnerable to tariffs, port delays, geopolitical disruption and quality issues. As a parts business with remanufacturing and allowance-heavy contracts, it also faces working-capital pressure and accounting complexity around cores, returns and variable consideration.
- Customer concentrationImpact: CriticalLikelihood: High
Sales are heavily dependent on a small number of large customers, so loss or repricing can materially reduce revenue and profitability.
Exposure: Three largest customers represented 86% of net sales in fiscal 2025.
- Foreign sourcing and import disruptionImpact: HighLikelihood: High
A significant portion of parts and components are sourced outside the U.S., exposing the company to tariffs, shipping delays and geopolitical shocks.
Exposure: Imports from China and other Asian countries are specifically cited.
- Pricing and allowance pressureImpact: HighLikelihood: High
Large customers negotiate lower prices, marketing allowances and payment terms, which can compress gross margin and increase working capital needs.
Exposure: Contract renegotiations and customer incentives are recurring.
- Inventory and core supply riskImpact: MediumLikelihood: High
Remanufacturing relies on returned cores and inventory realignment, which can create write-downs and supply mismatches.
Exposure: Core exchange programs and shelf-core revaluation are material to operations.
Accounting
Judgemental itemsMarketing allowances, discounts and returns reduce net sales and require estimation at each reporting date.
Impact: Affects reported revenue and gross margin
Returned cores are a key input and must be valued carefully, including shelf-core revaluation and NRV testing.
Impact: Affects inventory, contract assets and cost of sales
Foreign operations and lease liabilities create translation and derivative-related volatility.
Impact: Affects operating expenses and other income/expense
Past acquisitions added product lines and may require impairment reviews if performance weakens.
Impact: Affects balance sheet and potential impairment charges
