Seven & i Holdings Co. Ltd., the Japanese retail behemoth behind the ubiquitous 7-Eleven convenience stores, has been quietly undergoing a fascinating financial transformation, one that seems to have flown under the radar of most analysts. While headlines focus on the company's recent 3:1 stock split and its robust global expansion, a closer look at the financial data reveals a compelling story of strategic cash accumulation.

The most striking detail is the consistently negative net debt figure over the past few years. For the uninitiated, net debt is a measure of a company's overall debt burden, calculated by subtracting its cash and cash equivalents from its total debt. A negative net debt signifies that a company holds more cash and readily accessible liquid assets than it owes in debt. In essence, it's sitting on a pile of cash, a financial cushion that opens up a world of possibilities.

Now, this might not seem earth-shattering at first glance. After all, plenty of companies have healthy cash reserves. But Seven & i's situation is different. It's not simply holding onto a small surplus; its negative net debt has been consistently deepening, suggesting a deliberate strategy of cash accumulation.
