Board member Ranbir Singh (NVTS) holds 8.1% and presses for board changes

Rhea-AI Filing Summary

Navitas Semiconductor investor and director Ranbir Singh filed Amendment No. 2 to his Schedule 13D, updating his ownership and governance stance. He now directly beneficially owns 18,645,603 shares of Class A common stock, or about 8.1% of Navitas’s outstanding shares.

The shares were transferred to him from SiCPower, LLC in a private transaction on July 28, 2025 for an aggregate purchase price of about $163.9 million. SiCPower no longer beneficially owns any Navitas shares and is no longer part of a Section 13(d) group with Singh.

Singh, who has served on the board since November 2024, outlined concerns in an email to the board chair about director tenure, share ownership alignment, relevant expertise, and past capital raises. He indicated he may nominate at least two director candidates at the upcoming annual meeting if the board does not engage with him on these issues.

Insights

Activist & governance analyst

Singh consolidates an 8.1% stake and signals potential board challenge.

Dr. Ranbir Singh now directly holds 18,645,603 Navitas shares after acquiring them in a private transfer from SiCPower for about $163,894,850. SiCPower’s exit from ownership removes it from the Section 13(d) group, leaving Singh as the key reporting holder.

Singh’s email to the board chair raises concerns about long director tenures, limited share ownership among certain directors, board expertise in the core business, and prior dilutive capital raises. These points frame a governance-focused critique rather than an operational one.

He states he may nominate at least two directors at the upcoming annual meeting if engagement is unsatisfactory. That introduces potential board contest dynamics around the 2026 meeting, with outcomes depending on subsequent discussions and any formal nomination process disclosed in later filings.

Schedule 13D, beneficially owned, Section 13(d) group, Cooperation Agreement, +2 more

6 terms

Schedule 13D regulatory

"Dr. Singh will continue filing statements on with respect to his beneficial ownership of securities of the Issuer"

A Schedule 13D is a legal document that investors file with regulators when they buy a large enough stake in a company to potentially influence its management or decisions. It provides details about the investor’s intention, ownership stake, and plans, helping other investors understand who is gaining control and what their motives might be.

beneficially owned financial

"As of June 4, 2025, the Reporting Persons beneficially owned in the aggregate 22,406,419 Shares"

Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.

Section 13(d) group regulatory

"SiCPower no longer beneficially owns any securities of the Issuer and, accordingly, is no longer a member of a Section 13(d) group"

Cooperation Agreement regulatory

"previously entered into a Cooperation Agreement (as defined in Amendment No. 1 to the Scheduled 13D) with the Issuer"

A cooperation agreement is a formal contract between two or more organizations that lays out who will do what, how resources and responsibility are shared, how benefits or costs are divided, and how disputes or exits are handled. Like two chefs agreeing on a shared recipe and kitchen duties, it matters to investors because it can create new revenue paths, shift costs or risks, affect who controls key assets or technologies, and change a company’s future growth prospects.

Restricted Stock Units financial

"On August 6, 2025, Dr. Singh was granted 22,048 Restricted Stock Units for the 2025-2026 board term"

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

dispositive power financial

"Number of Shares Beneficially Owned by Each Reporting Person With: Sole Dispositive Power 18,645,603.00"

Dispositive power is the authority to decide the final outcome of an asset, legal claim, contract, or corporate action — in effect the power to dispose of or resolve something. For investors it matters because whoever holds that authority can determine who gets paid, who controls an asset or vote, and how risks and returns are allocated; think of it like holding the key that lets you lock in the winner or loser in a deal.

On April 23, 2026, Dr. Singh sent an email to the Chairman of the Board, Richard Hendrix, expressing his concerns with (i) the excessively long tenures of certain members of the Board, (ii) a general lack of alignment by such Board members who have sold most of their shares of the Issuer, (iii) the lack of relevant expertise and experience of certain members of the Board in the Issuer's core business, and (iv) the unnecessary and dilutive capital raises undertaken by the Board. Dr. Singh stated in the email that with the terms of three (3) long-tenured Class II directors expiring at the Issuer's upcoming annual meeting of stockholders, the Board should be thoughtfully refreshed by cycling off such directors who no longer have any meaningful skin in the game and adding new directors with relevant experience and fresh perspectives. Dr. Singh further stated that, to the extent the Board does not meaningfully engage with him to address these concerns, he intends to nominate at least two candidates for election at the Issuer's upcoming annual meeting of shareholders.
