If statement with Concatenate

[oreo haven]

OK,
So I have a group of rows with identical information (Column A). Column E has different info (in a query I ran, every line of data was listed in a new format). I need to concatenate E, but only if the cells in A are identical. Here's the kicker, it is not always the same number of rows.
Is this possible with a simple formula? Does anyone have a Macro that would fix this?

Thanks
