This is a little vague. MET is the largest by what measure? Revenue? I would suggest that you take a look at AllState's intro
It is very important that you explain to the reader how MET makes money. It invests the premiums that it is paid and earns a spread. As long as the premium + the spread is greater than total payouts they make money
Please put percentages and dollar amounts on your pie chart
Who are Met's customers
This section needs to be stregthened. Please take a look at allstate for an idea of metrics. Market Cap should not be included in this article anywhere.
You should defintely mention hurricanes specifically. How much did they cost the company in recent years. Interest rates and the yield curve should also be mentioned explicitly.
