From Chat GPT
Tang Capital, along with Perceptive Life Sciences, submitted director nominees for Penwest Pharmaceuticals and sought shareholder support via proxy cards opposing management.

They hold board seats in several biotech / pharma companies. For example, Kevin Tang is director or was director of multiple life sciences companies.

Taking stakes and pushing outcomes
Tang/Concentra (their acquisition vehicle) has made bids to buy entire biotech companies, sometimes while holding a significant minority stake, e.g., Kezar Life Sciences. They offered to buy all remaining shares and proposed contingent value rights to compensate for future drug program value.

They attempted with Acelyrin to intervene in a proposed merger with Alumis; Acelyrin adopted a βpoison pillβ defense offered, presumably because Tang was accumulating shares and making alternate offers.

Buy & shut ("zombie biotech") strategy
Concentra (Tangβcontrolled), seems to actively acquire struggling biotech companies (often called βzombie biotechsβ) and then shut them down, or otherwise crystallise value for shareholders. Thatβs a contrarian strategy that goes beyond passive investment.

So these are typical activistβinvestor behaviors: acquiring stakes, nominating directors, pushing for changes, trying to influence outcomes.
Where they differ from βtypical activistsβ
They donβt always seek to replace management, or at least not always in the public domain. Some offers seem more takeover / asset buyout focused rather than asking for board seats or governance overhaul in public view.
Some bids have been rejected, or met with defensive measures (e.g. the poison pill from Acelyrin) β so their activist style meets resistance.
BioSpace
Their focus seems quite specifically on biotech / life sciences, especially troubled companies, rather than broad sector activism. So their activism is more strategic / opportunistic rather than ideological or governanceβcentric across many industries.
Conclusion
Yes β Tang Capital is an activist investor in many respects: they take stakes, propose board representation or change, make takeover offers, and try to affect corporate outcomes.
