Yes — generally, the **Maximum Portfolio Investment Percentage** applies to the **total amount invested in a single portfolio company**, including both:
- the **initial investment**, and
- any **follow-on investments**
So if the cap is **10%**, that usually means the **combined exposure** to that company cannot exceed **10% of total capital commitments**, unless:
- your fund documents explicitly carve out an exception, or
- LPs / LPAC formally approve a waiver or amendment.
If a manager wants to concentrate more into a winner, they should check the LPA, PPM, and side letters carefully.
