Stephens analyst Tyler Stafford noted that FB Financial (FBK) has lowered its mortgage expectations for the second half of the year, which he sees being driven by softer volumes than originally expected coupled with incremental GOS margin pressure. Stafford thinks FB Financial's guidance may make investors incrementally more cautious around other mortgage heavy banks, he tells investors. On a list of banks with the largest GOS mortgage exposures as a percentage of revenue as of Q2 2018, Stafford identifies HomeStreet (HMST), Hilltop Holdings (HTH), Fidelity Southern (LION) and Flagstar Bancorp (FBC) alongside FB Financial.
