$SPRO CEO of Spero was CFO at $FULC this was the time frame she was there. Looking at their chart to see performance during her time there.

@Zackpedia· StockTwitsJul 10

$FULC You could’ve sold when I alerted and bought back at 3.4 now if you wanted.

@Zackpedia· StockTwitsJul 9

$FULC Down to 3.56, you could’ve sold when I alerted and bought back today if you wanted!

@jazzv· StockTwitsJul 9

$FULC what is co's exit plan? reverse merger?

@Zackpedia· StockTwitsJun 24

$FULC Went down to 3.66, you could’ve sold when I alerted…

@MikeyMcDermott· StockTwitsJun 24

"someone" is starting to anticipate some news re $FULC the stock is grinding higher since June 18.

@MikeyMcDermott· StockTwitsJun 24

Let's hope $SPRO & $GSK lose out on there "next phase of growth" for not acting swiftly and boldly. There is already a clean, willing and able cash shell $FULC in Cambridge with $300 million + cash. FULC was a sickle cell disease failure (unfortunately) but at least the Board MOVES quickly. -- cut 85% of staff; put in retention bonuses for remaining management/employees, cut burn rate drastically, all to drive a reverse merger. Shit is happening in Cambridge, MA.

@Zackpedia· StockTwitsJun 24

$FULC Selling time at 4!

@MikeyMcDermott· StockTwitsJun 22

$SPRO if Spero and GSK lost its reverse merger partner to say $FULC -- why not just take that Cambridge MA Nasdaq shell that has 300 million plus and a WILLING management and Board? If SPERO / $GSK TOOK TOO LONG AND LOST OUT TO FULCRUM THERAPEUTICS -- WHERE IS THE NEXT GROWTH OPPORTUNITY? IF THERE IS NONE ----- PERHAPS WE DO SEE A TENDER OFFER FROM GSK TONIGHT BEFORE THE AGM IF NO REVERSE MERGER PARTNER, THEN NO NEED FOR 120 MILLION NEW SHARES

@MikeyMcDermott· StockTwitsJun 22

$SPRO might have lost reverse merger partner to $FULC ? FULC already clean shell with 300 million in the bank. And they already let go 85% of staff. Only 9 employees vs Spero fat pig at 20+!!! These are all Cambridge Massachusetts outfits. Big competition to land their deals? Esther actually came to Spero from Fulcrum! Lots of people in the know I would guess. These are just wild ass guesses but something don't seem right
