My perspective using stake in PEL11/Advent as a baseline....
Market cap of MMR is current around $75 million, $115 million including all exercisable options for a 51.1% in Advent.
GBA has a market cap of $10 million ($11 million fully diluted) for a 14% stake in Advent (8.75% + 4.3% (via 8.4% of MMR and around 1% via BPH).
Taking relative market cap's into the equation GBA still undervalued relative to MMR....and compared to BUY (with a direct 15% stake relative to GBA's 11.5%) with a market cap of $75 million way way undervalued.
The percentages speak for themselves....
