Narrative:

At approximately 300 ft AGL on an ILS approach to runway 18L at memphis, observed an light transport at left 11 O'clock co-altitude and approximately 500 ft horizontal. Turned slightly into him (left as he was headed west) and increased descent to avoid midair collision. After he passed to right of us, tower advised us of him. He was on a go around, or taking off on runway 27. See and avoid saved us, not sure if he even saw us. (He was on a different tower frequency.)
