Red Flags

2025-08-28 → 2026-08-28

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) 14 REAL WARNINGS · 5 matching docS this year · 36 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] 10-Q FILED 2025-11-12 · [2] 10-Q FILED 2026-08-04 · [3] 10-K/A FILED 2025-11-12 · [4] 10-Q FILED 2026-05-12 · [5] 10-K FILED 2026-03-30

Reverse stock split AT LEAST 24 REAL WARNINGS · 11 matching docS this year · 35 ALL TIME

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

EVIDENCE: [1] 8-K FILED 2026-08-27 · [2] 10-K/A FILED 2025-11-12 · [3] 10-Q FILED 2026-08-04 · [4] 10-Q FILED 2026-05-12 · [5] 8-K FILED 2026-04-01

Going concern doubt AT LEAST 75 REAL WARNINGS · 10 matching docS this year · 41 ALL TIME

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

EVIDENCE: [1] 10-Q FILED 2025-11-12 · [2] 10-Q FILED 2026-08-04 · [3] 10-K/A FILED 2025-11-12 · [4] 10-Q FILED 2026-05-12 · [5] 10-K FILED 2026-03-30

Delisting / exchange risk 2 REAL WARNINGS · 2 matching docS this year · 14 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] 8-K FILED 2026-04-01 · [2] 10-K FILED 2026-03-30

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.

Breaking Filing

8-K · 2026-08-27

An 8-K is the "something happened right now" filing. Here is what this one says, in the company's own words.

Item 5.07

HOW THE BRACKET IS BUILT: BOOK EQUITY OF $1.09/SHARE AT 0.5-1.0X · MULTIPLES STRIPPED: UNDER A YEAR OF CASH AT THE CURRENT BURN, SO THE BRACKET CAPS AT WIND-DOWN CASH · CASH FLOOR: $0.2971/SHARE IN A WIND-DOWN.

BASIS FOR

+1

Share count is stable-ish (+8.1% change between the last two reported quarters).

+2

Fair-value range anchored to cited facts: $0.5433 to $0.5433 per share.

AGAINST

−1

Cash of $1,391,000 funds under half a year of operating burn, a hard going-concern pressure without fresh capital.

−2

Revenue fell 100.0% period over period.

−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.
