Proximus PLC (BGAOF), the Belgian telecom powerhouse, might be sitting on a financial puzzle that's baffling analysts. A close look at their recent financial data reveals a discrepancy so glaring, it could point to a hidden treasure trove of value or a strategic misstep of epic proportions.

The mystery centers on the company's net working capital. While Proximus enjoys a robust market capitalization of over $3 billion, their net working capital has consistently been negative, often exceeding a billion dollars. In the first quarter of 2024, their net working capital plunged to a staggering -$63 million. This isn't a recent phenomenon; the trend of deeply negative net working capital stretches back through available data to 2017.

Now, a negative net working capital isn't inherently bad. It can actually be a sign of efficiency, especially for companies like Proximus that operate with recurring revenue models. They collect substantial payments upfront from their customers for their services, meaning they have a pool of cash readily available to settle their short-term obligations.

However, the sheer magnitude and persistence of Proximus's negative net working capital raises some intriguing questions. Is this a calculated strategy, a reflection of their dominance in the Belgian market, or a potential red flag that needs further investigation?

Hypotheses:

Hypothesis 1: The Belgian Advantage

Proximus might be leveraging its strong market position in Belgium to negotiate extremely favorable terms with its suppliers. This could involve extended payment periods, giving them ample time to collect customer payments before needing to settle their own bills. Such a scenario would explain the negative net working capital while simultaneously demonstrating their market power.

Hypothesis 2: The Cash Conversion Conundrum

The second hypothesis centers on the concept of cash conversion. Proximus's business relies on substantial infrastructure investments. If they are slow to convert their investments into cash-generating assets, it could lead to a prolonged period of negative net working capital. This could stem from delays in project completion, regulatory hurdles, or even strategic decisions to focus on long-term growth over immediate cash flow.

Hypothesis 3: The Hidden Asset Play

The most intriguing hypothesis, though speculative, is that Proximus is deliberately building up a hidden reserve of assets. This could involve off-balance sheet financing, where assets are held in separate entities but are ultimately controlled by Proximus. This could be a strategic move to shield assets from taxes or create a reserve for future acquisitions.

The Numbers Tell a Story

Examining the financial data, we see that Proximus's short-term investments have also been consistently negative, often mirroring the negative net working capital. This suggests they are not holding liquid assets in readily accessible accounts. Instead, their cash flow statements show significant "other cash flow from financing activities," which could point to complex financing arrangements not readily apparent on the balance sheet.
