subleased for double the rate of the master lease and a contract to manufacture their product
They spiffed up the good area for $17M and subleased it out for something like $350K (not bothering to look it up).
NWBO rent on the dead space is more than what Advent pays on the GMP space.
And the manufacturing agreement is a windfall for Advent. They keep making $5.1M/y to produce around $1.5M/y product. Cognate had the same great deal until LP sold them.
