RISK INDEX
RED FLAGS 84 RUNWAY 3 YEARS-LONG PATTERN 6 = 93/100. WHY THIS NUMBER, PIECE BY PIECE.

THE READ 37 red-flag mentions across this year's filings, led by dilution and reverse stock split, and 241 since 2001, so this is a long-running pattern; share count shrank 87% over the past year (shrinking, not printing).

01

Red Flags

2025-10-13 → 2026-10-13

We read every document this company filed with the SEC this year and counted the classic danger phrases. Where wording can be misleading, we open the actual documents and separate real warnings from accounting boilerplate. Each hit links to the exact document.

Dilution (at the market offering) AT LEAST 4 REAL WARNINGS · 14 matching docS this year · 71 ALL TIME

An ATM lets the company print and sell new shares into the market any day it wants. Every print dilutes your slice.

EVIDENCE: [1] 8-K FILED 2026-07-06 · [2] 8-K FILED 2026-05-28 · [3] 8-K FILED 2026-07-23 · [4] 8-K FILED 2026-07-06 · [5] 8-K FILED 2026-06-01

Reverse stock split AT LEAST 20 REAL WARNINGS · 13 matching docS this year · 39 ALL TIME

A reverse split shrinks the share count to lift the price above $1. Repeat reverse splits are the classic death-spiral signature.

Going concern doubt AT LEAST 5 REAL WARNINGS · 7 matching docS this year · 96 ALL TIME

Auditors flagged substantial doubt the company survives the next 12 months without new money.

Delisting / exchange risk 8 REAL WARNINGS · 3 matching docS this year · 35 ALL TIME

The exchange has threatened to kick the stock off. Delisting pressure usually ends in a reverse split or a fire-sale raise.

EVIDENCE: [1] 10-Q FILED 2025-11-14 · [2] 8-K FILED 2026-06-01 · [3] 10-K FILED 2026-03-31

The Printing Press

How many shares exist, over time, exactly as the company reported in its own filings. In microcaps, a rising share count is how holders pay for everything: salaries, debts, and bad deals. Sudden collapses in the line are reverse splits, marked below.

Cash Countdown

Cash in the bank against how fast the company burns it. When this hits zero, the next stop is usually a desperate raise at bad terms, and existing holders pay through dilution.

Critical 8-K Ledger

OFFICIAL NOTICES · 24 MO

When something material happens, the company itself must announce it in an 8-K under the SEC's numbered item system. These are those announcements, newest first: bankruptcy papers, exchange delisting warnings, auditor changes, financials pulled back. Read straight from the SEC filing index, no interpretation layer.

LAST CLOSE
non-realtime

HOW THE BRACKET IS BUILT: BOOK EQUITY OF $1.44/SHARE AT 0.7-1.5X · CASH FLOOR: $1.45/SHARE IN A WIND-DOWN.

BASIS FOR

+1

Shares outstanding grew 25.8% between the last two reported quarters, a heavy dilution event.

+2

Fair-value range anchored to cited facts: $1.01 to $2.17 per share.

AGAINST

−1

Cash of $9,889,000 funds only about 1.9 years of operating burn.

−2

The filings do not publish comparable revenue figures for two consecutive periods, so the revenue trend could not be measured.

−3

Verified going-concern warnings in a recent filing: auditors or management flagged substantial doubt about continuing (document text checked, boilerplate excluded).

METHOD: DETERMINISTIC RULES OVER CITED SEC FILING FACTS: SHARE-COUNT CHANGE BETWEEN THE LAST TWO REPORTED QUARTERS (DILUTION), CASH-TO-BURN RUNWAY FROM THE MOST RECENT OPERATING CASH FLOW, PERIOD-OVER-PERIOD REVENUE GROWTH, AND A FAIR-VALUE RANGE ANCHORED TO CASH PER SHARE VS PRICE. THRESHOLDS ARE TUNABLE IN APP/VERDICT_ENGINE.PY. NOT A PREDICTION.

INSIDERS SPENDING THEIR OWN MONEY AT THESE PRICES IS THE STRONGEST VOTE OF CONFIDENCE THE FILINGS CAN SHOW.
