A transformative strategic move for SMP was the acquisition of Nissens Automotive on November 1, 2024, for approximately $397.1 million. This acquisition established Nissens as SMP's fourth operating segment, significantly expanding its geographic reach, particularly in Europe, and diversifying its sales mix, with U.S. sales now representing about 70% of the total, down from approximately 90% a few years prior. Nissens, a leading European supplier of thermal management and engine efficiency products, brings a strong brand profile and a well-received go-to-market strategy, contributing significantly to SMP's top and bottom lines. For the nine months ended September 30, 2025, Nissens Automotive generated $241.3 million in net sales and $23.4 million in operating income, outperforming its markets with mid- to high single-digit growth. Management expects Nissens to be an approximately $260 million annual business with mid-teens EBITDA, and anticipates revenue synergies to materialize starting in 2026.

The integration of Nissens is well underway, with a target of $8 million to $12 million in run-rate cost reduction synergies within 24 months, primarily through product cost optimization, supplier consolidation, and leveraging combined spend. Cross-selling opportunities are being actively pursued, including the introduction of over 800 new SKUs to the Nissens North American customer base and the development of programs for Europe, with sales lift expected in 2026.

In parallel, SMP is enhancing its North American distribution capabilities with the official opening of its new 575,000 square-foot state-of-the-art distribution center in Shawnee, Kansas. This facility, nearing completion of its capital spending phase, is designed to expand capacity, provide redundancy for risk mitigation, and improve customer service by optimizing the balance of activities across SMP's network. While the Shawnee DC is expected to incur approximately $3 million to $4 million in net higher costs from its 2023 baseline due to lease expenses and higher depreciation on automation, these costs are anticipated to improve in 2026 as duplicate expenses are eliminated. The company is also executing restructuring initiatives, including a Separation Program (expected to be substantially complete by end of 2027) and a Cost Reduction Initiative (expected to be substantially complete by end of 2026), aimed at optimizing its cost structure and improving operating efficiencies.

This growth was substantially bolstered by the inclusion of Nissens Automotive, which contributed $241.3 million in net sales. Excluding Nissens, the legacy business still achieved nearly 4% growth.

Profitability metrics also showed improvement. Gross margins for the nine months ended September 30, 2025, expanded to 31.1% from 28.8% in the prior year. This was driven by higher sales volumes leading to favorable manufacturing cost absorption, improved operating performance, and effective cost control measures. The Temperature Control segment, in particular, saw its gross margin percentage increase by 2.8 percentage points to 33.4%, benefiting from strong customer demand and market share gains, with Q3 2025 sales up 14.8% to $144.66 million. The air conditioning season's elongation contributed to robust sales, with customer point-of-sale (POS) for large accounts in Vehicle Control up mid-single digits in Q3 2025.

Operating income for the nine months ended September 30, 2025, surged by $38.2 million, including $23.4 million from Nissens Automotive and $14.8 million from higher net sales in legacy segments and cost control in Temperature Control. Consolidated operating income for Q3 2025 was $47.64 million, representing a 9.5% operating margin, up from 9.3% in Q3 2024. Selling, general and administrative (SG&A) expenses increased by $32.2 million in Q3 2025, primarily due to the inclusion of Nissens Automotive's SG&A of $24 million. Interest expense rose to $7.39 million in Q3 2025, reflecting higher average outstanding borrowings used to fund the Nissens acquisition. The effective tax rate for Q3 2025 was 28.5%, up from 25.7% in the prior year, due to higher earnings in foreign jurisdictions.

Liquidity remains sound. Cash provided by operating activities for the nine months ended September 30, 2025, was $85.7 million, an increase of $7.5 million year-over-year, supported by higher net earnings and effective working capital management. Capital expenditures for the period were $29.3 million, returning to normal levels following significant investment in the new Shawnee distribution facility. As of September 30, 2025, net debt stood at $502.3 million, with a leverage ratio of 2.6x adjusted EBITDA.

The company is on track to reduce this to a target of 2x by the end of 2026, supported by its $750 million credit facility maturing in September 2029. SMP also increased its quarterly dividend to $0.31 per share in February 2025, underscoring confidence in its financial health.

Outlook and Risks: Charting a Course Through Uncertainty

Management's outlook for 2025 reflects confidence in SMP's strategic direction and operational capabilities. The company has raised its full-year sales guidance to an increase in the low to mid-20% range over last year, driven by the robust performance of the first nine months and the full-year contribution of Nissens Automotive. The adjusted EBITDA margin outlook has been tightened to the upper end of the previous range, now expected to be between 10.5% and 11% of net sales. This guidance incorporates the impact of higher tariff costs and their offsetting pricing adjustments, which management expects to largely offset in the second half of 2025.

Key assumptions underpinning this positive outlook include the continued resilience of the North American aftermarket, the successful integration and market outperformance of Nissens Automotive, and the effective pass-through of tariff-related costs to customers. Management anticipates interest expense to be approximately $32 million for the full year, an income tax rate of 27%, and depreciation and amortization to be between $40 million and $45 million, reflecting the amortization of Nissens' intangibles and the Shawnee DC investments.

Despite this optimistic outlook, several risks warrant investor attention. The fluid and uncertain tariff landscape remains a primary concern, with potential for new or increased tariffs impacting costs, although SMP's North American manufacturing footprint provides a structural advantage. Macroeconomic uncertainty, including future increases in interest rates and inflationary cost pressures in raw materials, labor, and transportation, could materially impact estimates if not fully offset by pricing actions. The company's reliance on supply chain financing arrangements also presents a risk; termination of these arrangements or significant increases in benchmark interest rates could adversely affect liquidity and cash flows. Furthermore, the ongoing asbestos-related liabilities, which resulted in a $34.17 million loss from discontinued operations in Q3 2025, represent a long-term contingent liability that requires continuous monitoring.
