Good observation. That's not th standard as people here claim. Companies often play such games. Esp to make their IPO look attractive. I went over Squarespace S-1 today who IPOed in May and saw they claim around 70% revenue growth in commerce from 2019 to 2020. Then somewhere in the document you find that they acquired a company in March 2021 but they include their revenue in their 2020 numbers. So the 70% growth is not really organic growth and they don't mention anything about the growth of the acquired company (Tock).
