Manufacturing costs (Cost of Goods Sold) are clearly benefiting from scale, given the strong top-line performance. For the third quarter of 2025, Bel Fuse Inc. reported a gross profit margin of 39.7%, which is a nice step up from the 36.1% seen in Q3 2024. This margin expansion shows the leverage gained from higher sales volumes, which helped absorb fixed costs better, even as they manage currency fluctuations in places like Mexico and China. For the upcoming Q4 2025, management guided for the gross margin to remain healthy in the 37% to 39% range, despite anticipating normal seasonal patterns.

The company is actively managing its physical footprint, which translates into specific restructuring costs. You're seeing the financial impact of these moves:

• The transition of operations from a facility in China to a subcontractor was expected to wrap up by December 2025, a key cost-reduction effort.
• The restructuring initiative at the Glen Rock, Pennsylvania facility was ongoing, with full completion targeted for early 2026.
• Accrued restructuring costs stood at $1,315 thousand as of March 31, 2025, down significantly from $5,823 thousand at the end of 2024.

Depreciation expense, which flows into COGS and SG&A, was $3.0 million for the three months ending March 31, 2025.

The integration of the Enercon acquisition is also a factor in the cost base, specifically within Selling, General, and Administrative (SG&A) expenses.

The company is focused on realizing benefits from this deal, which enhanced the Power Solutions and Protection segment, seeing a 94% revenue increase in that segment.

Research and development (R&D) expenses aren't explicitly detailed for the recent quarters in the same way as the other line items, but historical context shows a pattern of cost management in this area, such as moving R&D jobs from Hong Kong to China and eliminating several positions in the past.

The most significant non-operating cost event impacting Q4 2025 is the Innolectric impairment charge. Due to insolvency proceedings initiated on November 26, 2025, Bel Fuse Inc. expects to record a pre-tax impairment charge of up to approximately $14 million in the fourth quarter of 2025. This estimate reflects the full potential loss on the investment, including outstanding notes receivable. Before this anticipated write-down, Bel Fuse had already recorded losses related to its noncontrolling minority interest in Innolectric of $0.4 million for the nine months ended September 30, 2025, and $0.6 million for the year ended December 31, 2024.

Here's a snapshot of some key cost-related figures we have for the recent period:

The company is actively working to reduce costs through facility consolidation and the China transition, which should help stabilize the ongoing operating expense base, though the Innolectric event is a major, non-recurring hit to Q4 costs. Finance: draft 13-week cash view by Friday.
