Winston Score History

The full picture

Midsummer AB is a Swedish company that makes solar panels designed to be installed directly on rooftops, replacing traditional roof tiles. Its main product is a thin, lightweight solar panel called BOLD, which is built for residential homes and commercial buildings. The company sells its panels across Europe and also licenses its manufacturing technology to other solar producers around the world.

Midsummer earns money in two ways: selling its solar roofing products directly to customers, and licensing its proprietary manufacturing process to third parties. The company is headquartered in Stockholm and operates primarily in European markets, where demand for building-integrated solar is growing. Its technology license model gives it a potential edge, since it can earn revenue without building every panel itself. However, with a negative operating margin and negative return on invested capital, the company is not yet profitable, and its main challenge is scaling revenue fast enough to cover its costs before competition from larger solar manufacturers intensifies.

Strong grower

Midsummer AB (publ) is growing revenue at 29% year-over-year. The Winston Score penalises unprofitable companies, but revenue at this pace tells a different story — this is a company still in "build mode."

The Winston Score above measures business quality today. Growth stocks often score lower because they invest in the future rather than maximising current profits. These metrics show what matters most for evaluating that future.
