Often when trying to match things, I find it easier to match what's there, then change it.
Matching the angle and skew of "corporation" is fairly easy.
Type the word, all caps, in a similar font (this appears to be some flavor of Helvetica Medium). I eyeballed the size based on the "C". Just free scaled the type until the Cs were close in size.
Using the Free Transform Tool with the new text highlighted, click the right side handle of the bounding box and then hold down the Command/Ctrl key and drag it up so the new type overlaps the old type. You should be able to get fairly close.
Then just change the type, and scale it if necessary.
You can then delete to the old type (which is outlined and why it's all separate pieces)
CS6 animation so cursors and highlights will be different if using a CC version, but the functionality is all the same
If you are looking to replace the "AES" you may have another issue. Using the above information will get you the same angle as the "AES" However, the angle of the
A is what is used to align the graphic on its left. There's no additional skew to the "AES". It uses the natural angle of the A. So, replacing the A with an I means you will need to either introduce some sort of additional skew, or edit the graphic to match the angle of the new I.
