This is licit.
See affirmative response from apologist Michelle Arnold, in Can a layperson give a talk after a short homily?
In my parish, we have, about four times a year, a short homily followed by an address from a layman or religious. These addresses are usually a report from a mission field, or the biannual fund-raiser.
If this were frequent and/or without an apparent justification, then you would have some cause for concern, but once in a while, for a good reason, is acceptable.
Thanks for clarifying the issue.
