RED FLAGS 53 RUNWAY 14 YEARS-LONG PATTERN 2 = 69/100. WHY THIS NUMBER, PIECE BY PIECE.

THE READ 18 red-flag mentions across this year's filings, led by dilution and reverse stock split; share count roughly stable; only about 3 months of cash at the current burn rate.

Red Flags

2025-08-30 → 2026-08-30

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) 13 REAL WARNINGS · 4 matching docS this year · 10 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 2026-05-08 · [2] 10-Q FILED 2026-08-07 · [3] 10-Q FILED 2025-11-05 · [4] 10-K FILED 2026-03-09

Reverse stock split 3 REAL WARNINGS · 5 matching docS this year · 14 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 2026-06-23 · [2] 8-K FILED 2026-06-23 · [3] 8-K FILED 2026-06-23 · [4] 10-Q FILED 2026-08-07 · [5] 8-K FILED 2026-06-23

Going concern doubt CLEAN

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

Delisting / exchange risk 2 REAL WARNINGS · 2 matching docS this year · 7 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 2026-06-23 · [2] 10-K FILED 2026-03-09

SOURCE: FULL-TEXT SEARCH OF THE COMPANY'S OFFICIAL SEC FILINGS. "REAL WARNINGS" = WE OPENED THE LINKED DOCUMENTS AND FILTERED PHRASES WRAPPED IN NEGATIONS, RESOLUTION LANGUAGE OR STANDARD CONTRACT TERMS. "AT LEAST" = MORE DOCUMENTS CARRY THE PHRASE THIS YEAR THAN WE COULD OPEN AND READ.

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.

22,254,537 shares · 2024-05-06 22,747,985 shares · 2026-08-05 LAST 12M: +1.6% AVG/YEAR SINCE 2024: +1.0%

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.

Revenue

Revenue: nothing to compare. This company's filings do not publish us-gaap:Revenues, so no honest change can be computed.

Cash burn / runway

Monthly operating cash deficit ~$6.08M ($-35.95M over the period ended 2026-06-30 in 10-Q). Against $20.21M cash is roughly 0.3 years of runway (3 months).

NOW: $-35.95M as of 2026-06-30 (10-Q, filed 2026-08-07)

Breaking Filing

8-K · 2026-08-28

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

Item 1.01

As previously announced, on June 22, 2026, Boundless Bio, Inc., a Delaware corporation (“Boundless Bio”), Boulder Merger Sub Corp., a Delaware corporation and wholly owned subsidiary of Boundless Bio (“Merger Sub”), and Serapha Bio, Inc., a Delaware corporation (“Serapha”), entered into an Agreement and Plan of Merger and Reorganization (as amended, the “Merger Agreement”), pursuant to which Merger Sub will be merged with and into Serapha, with Serapha surviving as a wholly owned subsidiary of Boundless Bio (the “Merger” and, together with all of the other transactions contemplated by the Merg...

The Verdict

AVOID · HIGH CONFIDENCE

A rules-based reading of the cited filing facts: a range with reasons, never a prediction.

HIGH confidence
$1.45-$1.45
FAIR VALUE BRACKET
book equity of $2.90/share at 0.5-1.0x
$2.83
LAST CLOSE
non-realtime

HOW THE BRACKET IS BUILT: BOOK EQUITY OF $2.90/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: $0.8886/SHARE IN A WIND-DOWN.

BASIS FOR

+1

Share count is stable-ish (+1.3% change between the last two reported quarters).

+2

Fair-value range anchored to cited facts: $1.45 to $1.45 per share.

AGAINST

−1

Cash of $20,213,000 funds under half a year of operating burn, a hard going-concern pressure without fresh capital.

−2

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

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. "10B5-1 PLAN" MEANS THE TRADE WAS SCHEDULED UNDER A PRE-SET TRADING PLAN, DISCLOSED IN THE FILING'S OWN FOOTNOTES: PRE-PLANNED SALES CARRY LESS SIGNAL THAN SPUR-OF-THE-MOMENT ONES.
