[SCHEDULE 13G/A] Reviva Pharmaceuticals Holdings, Inc. SEC Filing

Rhea-AI Filing Summary

Reviva Pharmaceuticals (RVPH) is reported to have 3,571,603 shares beneficially owned by CVI Investments, Inc. and Heights Capital Management, Inc., representing 4.9% of the outstanding common stock based on the prospectus supplement count of 68,003,613 shares. The reported holdings consist of shares issuable upon exercise of warrants, and the warrants are not exercisable to the extent that exercise would cause beneficial ownership to exceed 4.99%.

Heights Capital Management serves as the investment manager to CVI Investments and may exercise voting and dispositive power over the shares reported; both Reporting Persons disclaim beneficial ownership except for pecuniary interest.

Positive

• Transparent disclosure of beneficial ownership and the manager-client relationship between CVI Investments and Heights Capital
• Clear exercise limit on warrants (not exercisable to cause ownership >4.99%), reducing immediate control risk

Negative

• No sole voting or dispositive power is reported; holdings are shared rather than concentrated under a single controller
• Holdings are via warrants, which means actual equity interest depends on future exercise and remains contingent

Insights

Financial Analyst

TL;DR: A sub-5% position via warrants creates exposure without control; disclosure clarifies manager-client relationship.

The filing shows an economic stake of 3,571,603 shares (4.9%) held through warrants, with an anti-aggregation exercise cap at 4.99%, which prevents immediate expansion into a blocking or controlling stake. For investors, this represents a meaningful minority position that could convert into equity subject to the stated limits, but it does not imply control or concentrated voting power because the reported voting and dispositive powers are shared and expressly disclaimed except for pecuniary interest.

Corporate Governance Expert

TL;DR: Reporting is standard and transparent; manager-client structure and exercise limits reduce governance impact.

The Schedule 13G/A discloses that Heights Capital Management is the investment manager to CVI Investments and may be deemed to have voting and dispositive power over the reported shares. The filing also states that the warrants are not exercisable to exceed 4.99%, which limits any sudden shift in control. The reporting persons explicitly disclaim beneficial ownership beyond pecuniary interest, a common legal posture that clarifies governance exposure for Reviva.
