you have many mistakes in your writing. I see you have 2 overview in this writing: one in the first and two in the last. I suggest you should separate your writing into 4 paragraphs:

1st para: introduction
2nd para: overview
3rd para: body 1
4th para: body 2
you relay a lot of 'the percentage of company A,B,C,D' in your 2nd and 3rd paragraphs. you can replay them with 'the proportion of, the rate of'. and 'the percentage of company A'? the percentage of what??? you need to change these sentenses. you should not use 'the figure' for this writing because it is measured in percent. and 'the figure for' is only utilized for a particular number.

Hi there. Welcome again to the site! I hope my feedback gives you insight on how to improve your writing. Don't hesitate to approach us and ask for more information should you have additional queries!

In general, I find your writing to be a tad bit cluttered, especially because you were merging all of your analysis and interpretations into just one cluster of text. What you could have done to improve this writing would have been to incorporate a more strategic approach to writing to create a more compartmentalized approach to writing. For example, the second paragraph (that you have now) should have been sub-divided into three shorter ones to create different layers of analysis in writing as opposed to dumping everything in just one go.

The last concluding remarks should have also been improved to. Just merely stating that there is a highlighted growth that's visibly seen throughout those three years that have passed is insufficient. Try to be more innovative with your final remarks to make everything appear a lot more structured.

You should follow the structure: intro, overview, detail 1, detail 2 and line breaks between paragraphs.
Your article should skip the last overview.
Instead of looking at each company individually, you should group it. For example, group company A with company B because they are quite similar
