The primary driver of these increases was higher sales volume, which is discussed above, and improved operational execution. Operating income for the RF&S Components reportable segment remained consistent at $1.6 million for the quarter ended March 31, 2025, compared to $1.7 million for the quarter ended April 1, 2024. Operating margin rate for the RF&S Components reportable segment decreased to 18.0% for the quarter ended March 31, 2025, from 20.1% for the quarter ended April 1, 2024.
Liquidity and Capital Resources
Our principal sources of liquidity have been cash provided by operations, the issuance of debt, and borrowings under our revolving credit facilities. Our principal uses of cash have been to finance capital expenditures, finance acquisitions, fund working capital requirements, repay debt obligations, and repurchase common stock. We anticipate that financing capital expenditures, financing acquisitions, funding working capital requirements, servicing debt, and repurchasing common stock will be the principal demands on our cash in the future.
Cash flow used in operating activities during the first quarter of 2025 was $10.7 million as compared to cash flow provided by operating activities of $43.9 million in the same period in 2024. The decrease in cash flow from operations was primarily due to the timing of cash collections from customers which drove an increase in working capital.
Net cash used in investing activities during the first quarter of 2025 was $63.2 million, primarily resulting from the use of $63.3 million for purchases of property, plant, and equipment and other assets. Net cash used in investing activities during the first quarter of 2024 was approximately $42.6 million, primarily reflecting the use of $49.3 million for purchases of property, plant, and equipment and other assets, partially offset by $6.7 million of proceeds from the sale of property associated with our Shanghai E-MS subsidiary.
Net cash used in financing activities during the first quarter of 2025 was $18.8 million, reflecting the use of $17.9 million for repurchases of our common stock and $0.9 million for the repayment of long-term debt borrowings. Net cash used in financing activities during the first quarter of 2024 was $11.1 million, reflecting the use of $9.3 million for repurchases of common stock and $1.8 million for the repayment of long-term debt borrowings.
As of March 31, 2025, we had cash and cash equivalents of approximately $411.3 million, of which approximately $151.5 million was held by our foreign subsidiaries, primarily in China, and $195.6 million of available borrowing capacity under our revolving credit facilities. Should we choose to remit cash to the United States from our foreign locations, we may incur tax obligations which would reduce the amount of cash ultimately available to the United States. However, we believe there would be no material tax expenses not previously accrued for the repatriation of this cash.
Our total 2025 capital expenditures are expected to be in the range of $230.0 million to $250.0 million, of which approximately $66.0 million relate to our construction of our new plant in Syracuse, New York.
Share Repurchases
On May 3, 2023, our Board of Directors authorized a share repurchase program (2023 Repurchase Program) allowing us to repurchase up to $100.0 million of our common stock from time to time through May 3, 2025. During the quarter ended March 31, 2025, we repurchased approximately 0.7 million shares of our common stock for a total cost of $17.9 million (including commissions). As of March 31, 2025, the remaining amount in value available to be repurchased under the 2023 Repurchase Program was approximately $23.2 million.
Long-term Debt and Letters of Credit
As of March 31, 2025, we had $917.6 million of outstanding debt, net of discount and issuance costs, composed of $496.8 million of Senior Notes due 2029, $338.6 million under the Term Loan Facility due 2030 (Term Loan Facility), $80.0 million under the Asia Asset-Based Lending Credit Agreement (Asia ABL), and $2.2 million of other loans.
Pursuant to the terms of the Senior Notes due 2029 and Term Loan Facility, we are subject to certain affirmative and negative covenants, including limitations on indebtedness, corporate transactions, investments, dispositions, and restricted payments. Under the U.S. Asset-Based Lending Credit Agreement (U.S. ABL) and Asia ABL (collectively, the ABL Revolving Loans), we are also subject to various financial covenants, including leverage and fixed charge coverage ratios. As of March 31, 2025, we were in compliance with the covenants under the Senior Notes due 2029, Term Loan Facility, and ABL Revolving Loans.
