Neptune Insurance sees 15.02% stake disclosed
Neptune Insurance Holdings Inc. has a significant shareholder group led by BSIV Hold 101, LP and related Bregal Sagemount entities, together with Gene Yoon, reporting beneficial ownership of Class A Common Stock.
Rhea-AI Sentiment reads the wording of the document, how positive or negative its language is on a 1 to 5 scale. The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.

"The reported securities are directly held by BSIV 101... may be deemed to have voting and dispostive power"
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.
shared voting powerfinancial
"Shared Voting Power 14,252,718.00"
Shared voting power occurs when two or more parties jointly have the right to vote or decide how a block of company shares is cast, like co-owners who must agree before moving a piece of furniture. Investors care because who controls voting rights affects board elections, major corporate decisions and takeover outcomes, and shared control can alter regulatory disclosures and the practical influence any holder has over a company’s direction and value.
shared dispositive powerfinancial
"Shared Dispositive Power 14,252,718.00"
investment advisorfinancial
"Bregal LP, which is majority owned by Gene Yoon, is the investment advisor to BSIV 101."
An investment advisor is a person or firm that provides personalized guidance on buying, selling and managing investments and often oversees client portfolios for a fee. For investors this matters because the advisor shapes risk, costs and long-term returns, and is typically required by law to act in the client’s best interests — think of them as a financial coach or GPS that helps navigate choices and avoid costly detours.
percent of classfinancial
"Percent of class: ... The reported securities represent 15.02% of the outstanding Common Stock."
Percent of class is the portion of a specific category of securities—such as a company’s common shares, preferred shares, or a bond series—that takes part in or approves a corporate action (vote, consent, tender, etc.). Investors watch this number because it reveals how much support or opposition exists within that particular shareholder group; like counting how many members of a club back a proposal, it can determine whether a plan passes or how influence is distributed.
