The Write node passthrough does make certain assumptions when your output is 
exr. Try writing the file out and compare the written frames to your last node.

It gets worse..

Seems like it's also calculating a few other key operations in my comp 
differently when selecting EXR as the output format in a write. Besides the neg 
values below which seem to be coming from a grade, it also makes my Zblur and 
LensDistortion look different.

If I disable those 3 nodes, I get no difference between the last node and the 
write. If I enable ANY ONE of those nodes I get a slight difference in their 
calculation when viewing the write node only.

Bizarre. Serves me right for working on a Saturday.

So I have a fairly simple comp here and at the end when it goes to the write 
node, all of a sudden I get negative values. Take a look at the screen caps 
below and let me know if you seen anything like this.

If I switch the write node to dpx/Cineon the problem goes away. If I switch to 
exr/Cineon the problem stays so it seems to be something with the filetype 
being exr, not the colorspace.
