Merrimack Prescribed drugs (MACK) ($220MM market cap) is basically a publicly traded CVR in a c-corp type, I owned the inventory briefly in 2017 after the corporate bought Onivyde to Ipsen and dedicated to passing by way of any future milestone funds associated to Onivyde to shareholders. Sadly, it did not have the identical protections of a CVR and administration ended up diluting shareholders of these future milestone funds by elevating fairness to pursue their remaining growth stage pipeline. In 2019, the corporate formally gave up growth of latest medication, administration was eliminated and it has been little greater than a shell since as the corporate awaited any milestone funds from Ipsen.
Seven brief years later, Ipsen introduced that Onivyde was accepted by the FDA for metastatic pancreatic ductal adenocarcinoma (“mPDAC”), a very terrible type of pancreatic most cancers. This approval triggers a $225MM milestone cost to Merrimack, the remaining milestones for Onivyde and one other asset sale (to Elevation) are usually not anticipated to be reached. Merrimack waited little time to announce they had been formally liquidating pending a shareholder vote in Might, with the liquidation distribution vary of $14.65 to $15.35/share.
We’ll have to attend for the proxy to see how conservative this estimated vary is, however to my eye, it seems to be fairly conservative, with the precise distribution more likely to be on the high quality and even simply above. Beneath is my math, as standard, it is likely to be wildly off (and any variance to those numbers can swing the anticipated IRR fairly violently), I am significantly cautious of my tax estimate, any tax wizards on the market please be at liberty to chime in beneath within the remark part.
The corporate has $215MM in NOLs which nearly matches the Ipsen windfall, however taxes are nonetheless due beneath part 453A of the IRS code, which in my novice learn imposes an curiosity penalty on deferred gross sales like a milestone cost. The rate of interest relevant has different throughout the final 7 years, since I am only a retail man, I did not construct out a full mannequin, however I believe my quantity is roughly proper, possibly a contact low. The $0.03 distribution is solely a 50% haircut of my estimated escrow quantity to account for any bills through the liquidating belief lifecycle.
The board at MACK has been managed by buyers/homeowners since 2019, they have been prepping and making ready for this present day since, I do not anticipate any massive shocking bills or a lot of an escrow. Congratulations to that crew, I’ve adopted at a brief distance however by no means felt absolutely snug betting on an FDA approval.
