$SPRO If you want to back into a valuation figure for SPRO you need to think about the "worldwide" annual sales figures for Tebi awaiting imminent approval and phase 2 inhaled SPR720 (purchase pending from Vertex). We are easily talking billions and billions. The BO will most certainly reflect the "billions" in anticipated sales. It isn't difficult to see that $100/share is a possibility and $20 bucks reflects a base case scenario. All in my humble opinion and FWIW.

$ITRM It is totally sad. No clue how the author has expertise on so many topics. But, it is the only story that mentions little ITRM.. No acknowledgement about $ITRM elsewhere. Meanwhile no approved product $SPRO enjoys 4x marketcap. It is what it is until it changes.

$SPRO Nobody knows the Spero story. Nobody cares. Wall st has only an interest in the Mag 7 and for good reason. Every biotech in our space has crashed in price over the last 5 years - most far worse off than SPRO. The depressed share price over such a long period of time has rendered Spero a privately held company despite trading in a public marketplace. Even our longtime holders like Florestan capitulated. You should know that when SPRO pops to $10 it will start to turn heads and get public recognition.... and that will just be the beginning. I'm hanging on to just shy of 1% of this beauty and I have no intention to let go of a single share shy of the GSK purchase price. Pick your number - $20, $40, $60, $100. Every # works for me and every # can be justified because TEBI is that BIG! Godspeed fellow longs. It's time to sit back and enjoy the ride. It won't be long now.

$SPRO Again, so much bigger than anybody here can fathom. Tebi will be prove to be one of GSK's pride and joy high margin drugs that will sell in the multiple $$$$BILLIONS of dollars around the world. The FDA stopped the large scale worldwide study much earlier than anticipated for good reason - it's called compelling need and demand. This is going to go very very big. GSK already owns a sizable chunk of the company. No way that Spero can even considers selling close to under 2 billion. Don't be fooled by the milestone payments as a measure of Tebi's value. Tebi is HUGE. But first we need Vertex to show us the money for the SPR720 asset which is big in its own right. The upside for SPRO is simply ENORMOUS.

$SPRO the key factor or surprise element is gone in a typical bio buyout, and we are still under $3, it’s not realistic to expect multiple multiple from here in short term, i maintain $10 target if there will be an offer from gsk.

$SPRO Just insert "Spero Therapeutics" into this PR. https://www.gsk.com/en-gb/media/press-releases/gsk-completes-acquisition-of-bellus-health/ Look at the SPRO's recent PR announcing early termination of the study. GSK had to say:.... Spero had to say:.... The BO is coming very soon. A child could connect this dots!

$SPRO @mdboss That would be great but what makes you think that Vertex would buy back SPR 720 which they sold in 2016 to Spero and they suspended the development? Do you think that the suspension was because GSK wasn’t interested in that asset and told SPRO to sell it to make a Buyout happen? I’m very excited to hearing from you.

$SPRO The sale of SPR720 assets to Vertex takes us to $10 followed by an immediate BO at a 100% premium by GSK which occurs above $20. Perfection! Cha-ching!!!!!!!!!
