Substantial doubt about the company's ability to continue as a going concern.
“Based on the Company's current operating plans, management believes its cash and cash equivalents may not be sufficient to fund its operations for a period of one year following the issuance of these financial statements. As a result, there is substantial doubt about the Company's ability to continue as a going concern.”

Institutional ownership from SEC Form 13F filings. Investment managers with more than $100 million in U.S. equities must disclose their positions every quarter, within 45 days of quarter-end, so the holdings shown can lag the market by up to a quarter.
Institutional holdings are being reconciled with SEC filings. Holder totals and changes may be incomplete until reconciliation finishes.

Who Holds CALC
Last 8 quarters through Jun 30, 2026
Each kind of 13F filer's share of the common shares 13F filers report. Holder type comes from regulatory
records, never the filer's name; style, turnover and horizon are measured from each filer's own 13F book.
The quarter selector does not change this card.
Shares are 13F common shares restated to today's split basis; options and principal amounts are left out.
The change compares only filers with a 13F in both quarters and keeps each filer in its bucket of the later
quarter on both sides; a filer that continues under a new CIK is compared through its successor. Holder type
comes from each filer's current regulatory profile; client base and private funds come from the Form ADV roster
current at each quarter end (rosters from December 2019, so an earlier quarter reads Unknown). Style, turnover, horizon and
book size are measured from each filer's 13F book in the newest measured quarter, and Not measured means none
was. Actively managed books are those measured systematic-like, concentrated or diversified active.
Conviction and Crowding
31 13F filers, quarter ended Jun 30, 2026
Measured across every 13F filer's common-share book once the quarter's filing window closed. Crowding counts
filers with high turnover or that advise private funds on Form ADV.

Estimated Holder Cost Basis
Quarter ended Jun 30, 2026, on that quarter's share basis
Estimated, never filed: each 13F buy is costed at its quarter's average traded price and each sale keeps
the average cost, so this is what holders paid on average if they traded evenly through each quarter.

How fund types are measured
Each fund series counts once, with its latest Form N-PORT report dated inside the quarter; only long share
positions count, restated to today's split basis. The fund type is the series' latest Form N-CEN answer on or
before the quarter end (the index-fund box and the exchange-traded flag), never its name. Unclassified funds have
no usable N-CEN; unit investment trusts are among them, so index ownership is a floor. Funds sit inside their
advisers' 13F reports, so these shares overlap the 13F figures and are never added to them.

New and Sold Out count only filers that reported a 13F for both quarters: a first-time filer's book is not a buy, and a fund that has not filed, or withheld its positions under confidential treatment, has not sold.
