SIGNIFICANT CUSTOMERS AND GEOGRAPHIC NET REVENUES | 7. SIGNIFICANT CUSTOMERS AND GEOGRAPHIC NET REVENUES: Customer Concentration The Company’s top ten customers accounted for approximately 81% of net revenues for each of the three and six months ended June 30, 2025 and approximately 80% and 78%, respectively, in the corresponding periods of 2024. A significant portion of these revenues are attributable to sales of the Company’s products to distributors of electronic components. These distributors sell the Company’s products to a broad, diverse range of end users, including original equipment manufacturers (“OEMs”) and merchant power-supply manufacturers. Similarly, merchant power-supply manufacturers sell power supplies incorporating the Company’s products to a broad range of OEMs. Sales to distributors were $81.3 million and $156.5 million in the three and six months ended June 30, 2025, respectively, and $73.5 million and $139.9 million, respectively, in the corresponding periods of 2024. Direct sales to OEMs and power-supply manufacturers accounted for the remainder. The following customers represented 10% or more of the Company’s net revenues for the respective periods:
