⚠ Power Retail Is a Price BusinessModerate threat

Marubeni (8002) — threat to the moat

SmartestEnergy kept its market position and lost two-thirds of its profit, which says the position is not the moat.

SmartestEnergy's fall from ¥23.5 billion to ¥7.1 billion1 came without any loss of position; it remains third in the UK for sales to large consumers2. That is the nature of the business: the customer buys a commodity on price, and the retailer's margin depends on how well it hedges.

Same market position, a third of the profit.

Adding Factor Energia in Spain3 extends the model to another market with the same economics.

Retail power's profitability depends on how well the retailer's hedging matches its customers' consumption. SmartestEnergy aggregates power from independent generators as well as selling to large consumers4, so it carries price risk on both sides of its book.

The measure is SmartestEnergy's profit across two more years. A business that earns ¥23.5 billion one year and ¥7.1 billion the next has volatility, not a moat.
