Can an Interim CEO Become Permanent? How Conversion Works
Yes, and roughly one interim mandate in five converts. It works when the option is declared in writing at the start, when the board still runs a real external comparison, and when conversion is judged on results rather than on familiarity.
Why it works
The board has watched the person run the company for months with real numbers, real people, and real pressure. No interview process produces that quality of evidence. When the results are good and the fit is genuine, converting removes six months of search risk.
Why it fails
It fails when conversion becomes the unspoken goal. An interim who wants the permanent job avoids unpopular decisions, protects relationships that should be tested, and manages the board rather than the business. That is the single most expensive failure mode in interim leadership.
How to structure the option
- Write the possibility, or the exclusion, into the mandate letter
- Set the decision point at ninety days or at mandate end, not floating
- Define the outcomes conversion would be judged on before the work starts
- Keep an external benchmark: at least compare against a market shortlist
- Agree in advance what happens to notice and terms if the answer is no
