I have always wanted to write about Weathernews (market cap Y102 Bn). But, WN, one of the world’s largest private comprehensive weather information services, has always been expensive.

Climate change is increasing the frequency and severity of typhoons, floods, and heatwaves. Both corporations and governments are investing more in disaster prevention and early warning systems. This is an ongoing, structural driver of demand for Weathernews’ core forecasting and risk‐management services.  However, with 5/26 PE 29x, PB 4.42x, EV/EBITDA 14x, FCF Yield 4% against OP average growth of 17%, I would have to say that much good news is already in the stock.

But the stock declined 10% following the Q1 FY6/26 earnings release on October 9. While the results were broadly in line, they fell short of the 25% progress mark implied by full-year guidance. Management reiterated its annual targets, but investors were unforgiving given the stock’s elevated valuation.

Still, this pullback presents a timely opportunity to reassess whether this is a compelling entry point for a growth name—particularly if certain upside drivers remain underappreciated or not yet priced in.

In the note to my clients, I tried to surface things that others might’ve underappreciated. Some of them might be obvious, while others may be way off.
