Reviva Pharmaceuticals Holdings, Inc. gibt in der Schedule 13G/A an, dass die Tang‑bezogenen meldepflichtigen Personen gemeinsam das wirtschaftliche Eigentum an 3.399.975 Aktien der Stammaktien des Emittenten halten, was 4,8% der Klasse auf der Basis einschließt, dass diese Aktien derzeit durch Ausübung von Warrants ausgegeben werden können. Alle gemeldeten Aktien sind derzeit durch Ausübung der im Prospekt des Emittenten beschriebenen Warrants emittierbar; die Einreichung legt fest, dass Tang Capital Partners, LP 4.533.300 Investor Warrants hält, die jeweils für 0,75 einer Aktie ausübbar sind und Eigentumsgrenzen unterliegen, die die Beteiligung nach Ausübung auf 9,99% begrenzen (mit möglicher Erhöhung auf bis zu 19,99% nach Mitteilung). Die meldepflichtigen Personen geben an, über die gemeldeten Aktien gemeinsame Stimm- und Verfügungsmacht zu verfügen und erklären, dass die Position nicht dazu gehalten ist, die Kontrolle über den Emittenten zu ändern oder zu beeinflussen.

Positive
  • Transparent disclosure of beneficial ownership and voting/dispositive arrangements among Tang entities
  • Ownership below 5% (4.8%), consistent with non-control passive reporting under Schedule 13G/A
  • Clear contractual limits on warrant exercise that cap post-exercise ownership at 9.99% (with a potential increase to 19.99% after notice)
Negative
  • All reported shares are issuable upon exercise of warrants, representing potential dilution if exercised
  • Investor Warrants (4,533,300 held by TCP) convert at 0.75 share each, complicating straightforward share-count dilution calculations

Insights

TL;DR: Tang parties hold 4.8% beneficial ownership via warrants; position is below 5% and disclosed as not intended to influence control.

The filing shows an economically meaningful but sub-5% stake represented entirely by currently exercisable warrants totaling 3,399,975 shares on an as-exercised basis. Because the position is characterized as shared power among affiliated entities and limited by explicit ownership caps, this disclosure signals a strategic, monitored stake rather than an outright equity accumulation. The presence of Investor Warrants exercisable for 0.75 shares each and the stated ownership limits are material for modeling potential dilution and future voting dynamics, but the current reported percentage remains below thresholds typically associated with control or activist intent.

TL;DR: Reporting persons disclose shared voting/dispositive power and ownership limits; filing meets Schedule 13G/A transparency norms.

The statement clarifies beneficial ownership, allocation of voting and dispositive authority among Tang entities, and contractual limits on post-exercise ownership. These specifics are important for governance analysis because they define the scope of influence the group can exert and set automatic constraints on aggregate ownership following warrant exercises. The certification asserts the position is not held to change control, aligning the filing with passive-investor reporting under Schedule 13G/A rather than an active control-seeking disclosure.

However, TCP may increase such percentage to any other percentage, not in excess of 19.99% (to the extent such limit is required under applicable Nasdaq rules), by providing written notice to the Issuer, provided that any increase in such percentage shall not be effective until 61 days after notice is provided to the Issuer.
