Three risks warrant attention. First, currency. Roughly 50% of PG's revenue is generated outside the US dollar, which means a strong dollar cycle mechanically compresses reported revenue and margin. The FY2025 FCF step-down partially reflected currency headwind. A reversal would boost the number.
Second, private-label share. Across developed markets, private label share in key PG categories (laundry, paper products) has been gradually rising for a decade. That trend is probably structural, not cyclical. It caps the pricing power on commoditised categories and limits PG's ability to pass through input cost inflation without volume attrition.
Third, commodity cost volatility. PG's cost structure is heavily exposed to pulp, palm oil, plastics resins and energy. A synchronised commodity spike would compress gross margins in a way that would be difficult to offset with pricing in the first 12-18 months.
None of these risks breaks the per-share compounding engine. They adjust the pace. In a favourable cost environment the per-share FCF CAGR runs at the top of the 8-10% range. In an unfavourable environment it runs at the bottom. The 70-year dividend commitment remains intact either way.
A fourth risk, often underweighted, is the changing consumer preference toward direct-to-consumer brands in specific categories. DTC brands have taken 5-8% share in a handful of PG categories (men's grooming, certain beauty sub-segments). The share loss has been small in aggregate but persistent, and the vectoring matters. Management has answered with investment in its own DTC capability plus selective M&A. The trajectory is not alarming but it is worth monitoring.
