Boom time: Ru­bius, Cri­net­ics find big sup­port in up­sized IPOs to­tal­ing $343M raise

Thought Ru­bius Ther­a­peu­tics was am­bi­tious when it set terms for a $200 mil­lion IPO? Well, think again.

The Cam­bridge, MA-based biotech has just bagged $241 mil­lion by of­fer­ing 10.5 mil­lion shares at $23, both fig­ures above the orig­i­nal plan of 9.53 mil­lion shares be­tween $20 and $22 each. That brings Ru­bius’ mar­ket cap to $2 bil­lion — built sole­ly up­on its pre­clin­i­cal as­sets.

Join­ing Ru­bius in cel­e­brat­ing a big­ger-than-ex­pect­ed Nas­daq de­but is Cri­net­ics Phar­ma, the team of en­docrine ex­perts which nabbed $63.5 mil­lion to sup­port its nascent clin­i­cal work just weeks ago. In­stead of rais­ing $80 mil­lion, they bagged $102 mil­lion by sell­ing 6 mil­lion shares at $17 each, a mil­lion more shares than orig­i­nal­ly in­tend­ed sold at the high end of the range.
