This is more of an inscriptional serif than it is a slab.

It's not Penumbra Half-Serif, although that might do in a pinch.

I was going to say a customized Trajan, until I looked at Stephen's list. I think Mecanorma's Galba is closer. Almost the only thing it needs is to close the P. The C shape is what makes me choose it. The relative angle of the serifs seems like the PACIFIC lettering, even more than Trajan, and the serifs on the E and F are more like the sample.
