For the fiscal year ended December 31, 2025, Bel Fuse Inc. reported total net sales of $675.455 million ⁹, an increase from $534.792 million in 2024 ¹⁰. Gross profit for 2025 was $264.418 million ¹¹, resulting in a gross margin of 39.1% ¹². Operating income stood at $110.996 million ¹³, with an operating margin of approximately 16.4%. Net earnings available to common shareholders were $74.111 million ¹⁴. Diluted EPS for Class A common shares was $4.65 ¹⁵ and for Class B common shares was $4.90 ¹⁶. Cash and cash equivalents at December 31, 2025, were $57.800 million ¹⁷. Total long-term debt outstanding was $197.5 million ¹⁸. The company's current ratio was 3.0 to 1 ¹⁹ at December 31, 2025.

Year-over-year, net sales increased by $140.663 million, or 26.3%, from $534.792 million in 2024 to $675.455 million in 2025 ²⁰. The Power Solutions and Protection segment saw a significant sales increase of $111.3 million (45.3%) ²¹, primarily due to the Enercon acquisition. Connectivity Solutions sales grew by $11.9 million (5.4%) ²², driven by commercial aerospace and military markets. Magnetic Solutions sales increased by $17.5 million (25.4%) ²³, mainly from networking customers. Gross margin improved to 39.1% in 2025 from 37.8% in 2024 ²⁴. Material costs as a percentage of sales increased to 31.3% in 2025 from 29.7% in 2024 ²⁵, while labor costs as a percentage of sales slightly decreased to 7.7% in 2025 from 7.8% in 2024 ²⁶.

During 2025, Bel Fuse Inc. completed the accounting related to the Enercon acquisition, which closed on November 14, 2024, for an 80% stake, contributing $136.6 million in revenue to the Power Solutions and Protection segment in 2025 ²⁷. The company also initiated a restructuring within its Magnetic segment, transitioning manufacturing from its Pingguo, PRC facility to an outside subcontractor, incurring $1.6 million in restructuring costs ²⁸. Additionally, the company recognized gains on sales of properties totaling $5.7 million ²⁹, primarily from the sale of buildings in Zhongshan, PRC, and property in Glen Rock, Pennsylvania. An impairment charge of $13.1 million was recorded in Q4 2025 for the noncontrolling minority investment in innolectric and related party notes receivable, representing a full write-down ³⁰.

Management intends to maintain a strong competitive posture in the markets served by continued expansion of product lines and ongoing investment in research, development, and manufacturing resources. The company's backlog of orders as of January 31, 2026, is estimated to be approximately $452.2 million ³¹, an increase from $388.1 million as of January 31, 2025 ³². Management estimates that approximately 80%-85% of the backlog as of January 31, 2026, will be shipped by December 31, 2026 ³³.

A major growth area for the company is the integration and expansion of Enercon Technologies, Ltd., an 80%-owned subsidiary acquired in November 2024. Enercon is a leading supplier of highly customized power conversion and networking solutions for global aerospace and defense markets, providing robust solutions across air, land, and sea applications. For fiscal year 2025, approximately 93% of Enercon’s revenue was attributable to the defense end market and 7% to the aerospace end market ³⁴. Bel has the current intention to purchase the remaining 20% stake in Enercon by early 2027, in accordance with the terms and conditions of a shareholders’ agreement ³⁵. The company anticipates continued growth, synergies, and expansion from this acquisition, although the timing and magnitude of these opportunities remain uncertain.

Another growth vector involves the company's strategic alliance with innolectric AG, a Germany-based eMobility technology company, through a noncontrolling (one-third) investment made in February 2023 for approximately €8.0 million (approximately $8.8 million) ³⁶. This investment was intended to focus on Electric Vehicle (EV) on-board power electronics, particularly next-generation fast-charging technology. However, an impairment charge of $13.1 million was recorded in Q4 2025, representing the full impairment and write-down of this investment and related notes receivable, with no future recovery expected through the insolvency process ³⁷.

Operationally, the company expects labor costs as a percentage of sales to fluctuate based on product mix, with the Magnetic Solutions segment being most sensitive to these changes due to its labor-intensive ICM products. Labor costs in the PRC, Mexico, and Israel are primarily denominated in local currencies, making them susceptible to exchange rate fluctuations against the U.S. dollar. Minimum wage increases enacted in Slovakia, the PRC, the Dominican Republic, and Mexico during 2025 increased annual labor costs by approximately $1.8 million in aggregate ³⁸, and future wage increases are expected to exert upward pressure on labor costs and adversely affect profit margins. The company will continue to review its operations to optimize its business, which may result in restructuring costs being recognized in future periods ³⁹.

The company plans to allocate capital to various areas. Anticipated interest payments on long-term debt amount to $26.8 million, with $10.0 million expected to be paid in 2026 ⁴⁰. Planned capital expenditures total $2.0 million at December 31, 2025, with $1.4 million expected to be paid in 2026 ⁴¹. The company maintains a share repurchase program, authorized in February 2024 for up to $25.0 million ⁴², with approximately $2.1 million for Class A shares and $6.9 million for Class B shares remaining for repurchase as of December 31, 2025 ⁴³. Quarterly dividends of $0.06 per Class A share and $0.07 per Class B share were declared for 2025, 2024, and 2023, totaling $3.5 million in each year ⁴⁴. The company expects to pay $1.7 million in dividends in the first half of 2026 ⁴⁵.

The company faces structural headwinds and execution risks, including the potential for unanticipated difficulties in fully integrating the Enercon business successfully, particularly concerning the timing and magnitude of strategic and revenue opportunities. There is also a risk that the intended acquisition of the remaining 20% stake in Enercon by early 2027 may not be completed, which could disrupt plans, operations, and relationships ⁴⁶. Furthermore, demand in Enercon’s end markets, particularly defense, can be cyclical and sensitive to government spending, which may decrease or shift, materially adversely affecting the business ⁴⁷.

Geographic, regulatory, and macro factors also pose constraints. The company has substantial manufacturing operations in the PRC, exposing it to foreign currency exchange risk, labor shortages, and extensive government regulation, which could increase costs or limit operations ⁴⁸. Operations in Israel, following the Enercon acquisition, are subject to political and economic instability, military activity, and potential boycotts, which could disrupt operations and facilities ⁴⁹. Changes in trade policies and tariffs, particularly with the PRC and Mexico, could substantially increase operating costs, reduce demand, and disrupt the supply chain, with the USMCA review in 2026 potentially leading to less favorable terms ⁵⁰.

The company operates in a highly competitive industry with low barriers to entry, facing larger competitors with significant financial resources and technological capabilities, and relies on product performance, quality, reliability, depth of product line, customer service, technological innovation, design, delivery time, and price to compete. Acquisitions, a significant portion of the company's growth, may not produce anticipated results or integrate successfully, as evidenced by the $13.1 million ⁵¹ pre-tax impairment charge in Q4 2025 for the innolectric investment and related party notes receivable due to cessation of financial support from the majority owner and insolvency proceedings. The company's ability to develop new products is critical, with inherent risks in anticipating technological change and timely market introduction. Operational risks include potential labor unrest or shortages, particularly in the PRC where 42% of associates ⁵² and 56% of manufacturing facilities ⁵³ are located, and where labor availability is cyclical due to the Lunar New Year holiday. A shortage or increase in cost of raw materials, components, and other resources, including sharp increases in Gold (Au), Silver (Ag), and Copper (Cu) prices, may negatively impact profit margins. Demand in Enercon’s end markets, primarily defense (93% of Enercon’s 2025 revenue) ⁵⁴ and aerospace (7% of Enercon’s 2025 revenue) ⁵⁵, is cyclical and sensitive to government spending, which could materially adversely affect the business. Substantial manufacturing operations in the PRC expose the company to foreign currency exchange risk, labor cost increases, and extensive government regulation, including potential trade restrictions and tariffs. Operations in Israel, following the Enercon acquisition, are subject to political and economic instability, military activity, and potential boycotts. Financial risks include suffering margins due to declines in selling prices, increases in material and labor costs (e.g., $1.8 million ⁵⁶ aggregate increase in annual labor costs in 2025 due to minimum wage increases), and the imposition of tariffs, which could lead to reduced demand or higher costs. The Supreme Court's February 20, 2026, decision in Learning Resources, Inc. v. Trump, striking down certain tariffs, creates uncertainty regarding future trade policies, with approximately 25% of consolidated global sales having been subject to recently-enacted U.S. tariffs based on February 2025 information ⁵⁷. The USMCA review in 2026 could result in less favorable terms for Mexican manufacturing operations. Backlog figures, while totaling $452.2 million ⁵⁸ as of January 31, 2026, may not be reliable indicators of future sales due to potential customer delays, accelerations, or cancellations. The company's $197.5 million ⁵⁹ outstanding indebtedness at December 31, 2025, with a Leverage Ratio of 1.4x Consolidated EBITDA ⁶⁰, exposes it to risk in downturns and requires adherence to financial covenants, such as the Leverage Ratio not exceeding 3.50 to 1.00 ⁶¹. Legal, tax, and regulatory risks include potential patent infringement lawsuits, adverse developments in tax laws across multiple jurisdictions, and increasing costs and liabilities associated with global environmental and sustainability initiatives, including evolving ESG reporting requirements. Cybersecurity threats, including those amplified by AI, pose a risk to system integrity and data confidentiality, potentially leading to financial penalties, reputational damage, and operational disruptions. The loss of executive officers or other skilled associates could negatively impact operations and results.

Management's message to shareholders emphasizes a commitment to ethical and legal conduct, fostering an inclusive environment, and investing in associates through training and development. The company's human capital strategy is built around extraordinary performance, great associates, health and safety, and culture, with a goal of zero recordable incidents. Management highlights the importance of trust, integrity, and accountability, with policies and practices continually reviewed to align with the best interests of shareholders, associates, and other stakeholders. The company is committed to ESG matters, with Board-level oversight through its Nominating and ESG Committee and an internal ESG Committee providing quarterly updates. Management explicitly states its intention to maintain a strong competitive posture by expanding product lines and investing in R&D and manufacturing resources. The company estimates that approximately 80%-85% of its $452.2 million ⁶² backlog as of January 31, 2026, will be shipped by December 31, 2026 ⁶³. Furthermore, Bel has the current intention to purchase the remaining 20% interest in Enercon by early 2027 ⁶⁴ in accordance with the terms of the shareholders' agreement.
