.exr file missing background

No matter what i do, i always lose my backrgound when i render to .exr. Wherever there is alpha in the image, i see the empty checker pattern in photoshop, no information on the background whatsoever, hollow…

What may be causing this?

Photoshop…

It does the same thing with PNG, so i assume it’s Photoshops awfully bad Alphahandling once more. Tho i cant really proof it as i never use EXRs with PS.
