Analysis · ENTA · Life Sciences

The 23-year CEO is stepping down at a pivotal moment: Enanta is burning roughly $19.5M a quarter against $211.5M in cash and leaning on a $75M at-the-market facility to fund its RSV and immunology pipeline. Luly stays on as a strategic advisor through 2027, and the board is running a full internal-and-external search, so no successor has been named yet — that gap is the real uncertainty. Meanwhile, the simultaneous promotion of Tara Kieffer to a newly created COO role puts an operational leader in place and gives the board an internal option, but investors won't know the direction of the next CEO until the search concludes.
