Our balance sheet continues to get stronger, with cash and cash equivalents, other investments and marketable securities increasing to $102.2 million. We have no outstanding debt and the net cash provided by operating activities for the three months ended September 30, 2024 was approximately $12 million in Q1.
Mr. Soloway concluded, "Fiscal 2025 began with more record-breaking sales and profits. As fiscal 2025 progresses, we are very encouraged with the strength of our Starlink radios sales, particularly the Starlink Fire radio, which generates the most profitable recurring revenue and our expectation is that Starlink radio sales will remain strong. While we were disappointed in our overall equipment sales, we anticipate improvement in our locking sales once distributors complete the reduction of their inventory levels, which should lead to improved equipment revenue, improved equipment gross margins and the continuation of our very profitable recurring revenue. Our strong net income and Adjusted EBITDA*, coupled with the significant cash generated from operations continues to grow our cash position. We are pleased continue our dividend program and will be paying the next quarterly dividend of $0.125 per share on January 3, 2025. As always, we will strive to accomplish our goal of continued financial strength, product innovation, technical superiority, and strong profitability, for the balance of fiscal 2025 and beyond".
