I'd argue that Anathem and Seveneves had actual conclusions.

Possibly The Baroque Cycle though it's been a while since I'd re-read it.

His political fiction (Interface and The Cobweb) were also fairly traditional, though he had a co-author on those.

I love all his books, no hate.

Anathem had perhaps the biggest deux ex machina in literary history, and seveneves had an entirely separate novella for an ending.

Seveneves had a conclusion, and then an extra book...
