Abstract. Firms' investments in green technology are increasingly important for competitive positioning, yet whether these investments improve long-run performance remains unclear. Using electricity capacity data for global utility firms as a laboratory, we construct a unique structural measure of technological greenness based on renewable versus fossil fuel infrastructure. We find that adopting sustainable technologies is followed by a long-run improvement in fundamentals that is only partially reflected in stock prices, yielding superior returns over a multi-year horizon. We show that actual revenue growth drives these returns rather than investor sentiment, revealing a consumer-based mechanism that likely extends beyond the utility sector.
