Ownership

Who owns ISABELLA BANK CORP, from the filings themselves: stakes over 5% (Schedule 13D/G), the institutional managers reporting the stock each quarter (13F), and the funds holding it (N-PORT).

Stakes over 5%

Investors crossing 5% ownership must disclose it. Schedule 13G filers certify the stake is passive; Schedule 13D is the general form for everyone else — founders, strategic holders, and activists alike. Each entry is the holder's most recent disclosure. Coverage begins with SEC's structured filings from December 18, 2024; a holder appears once they file or amend after that date.

Super investors holding ISBA

Every institutional manager whose latest 13F reports this stock, largest position first. "% of their portfolio" is the weight inside that manager's own book — how much conviction the position represents; "% of company" is how much of ISABELLA BANK CORP they hold. Together these 73 managers report 27.83% of shares outstanding.

Funds holding ISBA

Funds disclosing this stock in their monthly N-PORT portfolio, with the position's share of the fund's net assets. Together these 47 funds hold 6.03% of shares outstanding — counted inside the manager totals above, not on top of them, since a fund's shares also appear in its manager's 13F.
