Both times I've seen this (yesterday and today) are after re-booting

management (or lack off?) that's leaving this parameter unset, or
possibly SMART is reading a small positive value incorrectly before
pending sectors have been cleared.

Does anyone else have any idea what might be going on? Drive is
obviously still in warranty, just want to know how concerned I need to
be.

It may be exactly that, an electrical failure of some sort that's intermittent. The current pending sector usually refers to sectors on the disk which are no longer readable but have not yet been remapped. A write to a bad sector causes the drive to remap it to a spare working sector. It doesn't make sense to me that it would be negative. Most drives have a bunch of spare, normally unused sectors for that purpose. Does smart report that the drive is in it's known database? If not, it could be a 'quirk' of that drive, but either way I'd make sure you keep a backup and if it's under warranty it maybe just as prudent to get it replaced.
