Be careful with your singular v. plural word usage. 5 is more than 1 and therefore, should be indicated in plural form. There should be a +S at the end of the word year (year+s).

Keep your discussion properly referenced. Use the chronological order of reference. There is no reason for you not to discuss the companies in a successive manner. The clarity of the discussion relies on the proper referencing or sequencing of information. Failure to do so will leave the readers confused and wondering about the appropriate next company information in the paragraph. This is something that you somewhat properly achieved in the last paragraph. That means you know how to properly discuss the information, you just got confused in the previous paragraph presentation.
