BGP default route with no next hop

Hi, I'm having trouble understanding how this VRF is able to route packages to a next hop IP address that is not directly connected and has no routes to the next hop IP address. The 185.191.234.110 IP is a Loopback interface in the global vrf on another router

sh ip route vrf Company

B* 0.0.0.0/0 [200/0] via 185.191.234.110, 7w0d

10.0.0.0/8 is variably subnetted, 6 subnets, 2 masks

B 10.10.92.0/24 [200/0] via 185.191.234.110, 3w0d

B 10.11.26.0/24 [200/0] via 185.191.234.110, 7w0d

B 10.109.0.0/30 [200/0] via 185.191.234.110, 7w0d

B 10.110.0.188/30 [200/0] via 185.191.234.110, 7w0d

B 10.110.0.192/30 [200/0] via 185.191.234.110, 3w0d

B 10.111.0.80/30 [200/0] via 185.191.234.20, 7w0d

sh ip route vrf Company 0.0.0.0
