Is Clearthink 1 Acquisition Corp. (CTAA) a good stock to buy?
Our tested checks disagree with each other, so the answer depends on something further down the page rather than on any one measure.
What each rating means, in numbers
Can it survive? — Middling. Safer than 54% of the companies we cover, judged on the warning signs that came before companies that really did fail.
What "tested" means here, and why there is no score out of 100
Tested means the read was measured against what actually happened afterwards, on a history that keeps the companies that were later delisted, using only figures that had been filed on the day they are used. Survival was ranked on companies that really did fail. What an owner keeps was tested across the universe from 2011 to 2025.
The full record of everything we have tested is on the research pages.
Which benchmark. Over the period we tested, the median listed company returned +5.8% a year while the S&P 500 returned about +13.9% — the index is weighted by size and was carried by a handful of enormous winners. So "beats the index" and "beats the other companies you could have bought" are different questions. Where a read says it picks better companies, it means the second one. None of these gets you an index fund's return, and we would rather say that than imply otherwise.
The quality read is the strongest thing we have tested: 131,000 company-quarters across 5,300 companies, where the weakest scorers went on to fail at 5.4% against 1.4% for the strongest, holding in every era and all twelve sectors. It still says less likely to break, not likely to beat the market — every band in that study lost to the index at the median, because the median listed company does.
Each read is shown on its own rather than merged into a single score, so you can see which part is strong and which is weak instead of taking an average on trust.

📍 Where to start on this page, and what to look at first
How to read CTAA (speculative micro-cap)
No model can pin a precise fair value on a company this small — but that does not mean there is nothing to learn. The useful questions are what the price is betting on, and whether the company can survive long enough to deliver it.
-
1
Reverse-DCF — what growth the price assumes ↓
The single most useful number here: it backs out the growth the market is paying for. If that figure is "historically unprecedented," the price is running on hype, not fundamentals.
-
2
Cash runway ↓
A pre-profit micro-cap lives or dies on whether it can fund itself to profitability before running out of money and diluting you.
-
3
The raw financial statements + the 10-K ↓
At this scale, the actual numbers, insider ownership, and share-count trend tell you more than any ratio.
It files little or nothing with the SEC — so our cash-flow models, financial statements, and U.S. insider data (Form 4) don't apply. What's still real: the live U.S. price and short positioning. Here's what we could pull from other sources:

Identity, share count and tier from FINRA + OTC Markets; not a substitute for the home-market financial statements. Thin U.S. disclosure + OTC trading is itself a risk factor.
Safer than 54% of the stocks we cover
What this rating means, and what it does not
What this rank is — Middling. Safer than 54% of the companies we cover. Out of every 100 companies ranked here, about <0.1% went bankrupt within the year, against 0.6% for the average company we cover. The rank comes from a model trained on every US filing since 2012, including 823 companies that really did fail, and scored each year by a version that had not seen that year.
What it is not — Not a trade. We tested shorting these names and buying puts, spreads, straddles and condors on them at real option prices, 2010-2025. Every version lost money: the market already prices the distress and the survivors squeeze. A high rank is a reason to read the filings and to size for a total loss, not a reason to bet against the company. A low rank says the balance sheet is calm, not that the price is sensible.
▾ The numbers, the logic, and why not to trade on it
The logic. A model trained on every US filing since 2012 — including 823 companies that went bankrupt or stopped trading under a dollar — ranks each covered stock by its chance of failing in the next year, from its latest filing, price history and credit conditions. The rank is a position among peers; the table is a count of what happened to stocks in each position, scored each year by a model that had not seen that year.
| Rank band | went bankrupt within 12 months | fell 80% or more (or failed) within 12 months | fell 50% or more (or failed) within 6 months |
|---|---|---|---|
| All covered stocks (average) | 0.59% | 4.21% | 8.51% |
| Finance (sector average) | 0.13% | 1.25% | 3.09% |
| riskiest 1% | 16.4% | 33.0% | 45.5% |
| next 2% (97-99) | 5.9% | 24.9% | 38.2% |
| next 2% (95-97) | 3.4% | 21.2% | 33.8% |
| next 5% (90-95) | 1.6% | 15.1% | 27.3% |
| next 15% (75-90) | 0.8% | 8.5% | 17.8% |
| next 25% (50-75) | 0.2% | 2.7% | 6.2% |
| safest half ← this stock | <0.1% | 0.5% | 2.1% |
Why not to trade on it. We tested shorting these names and buying puts, spreads, straddles and condors on them at real option prices, 2010–2025: every version lost money. The market already prices the distress, and the survivors squeeze. Use a high rank to read the filings and to size for a total loss — not to bet against the company. A low rank says the balance sheet is calm, not that the price is sensible.
Scored from the filing of 2026-05-18; table generated 2026-09-18. Within Finance: rank 65 of 100. Rough one-year odds for this stock alone: bankruptcy 0.1%, an 80% fall 0.5% (the model overstates the middle of the range).
▾ The logic, and why not to buy on it
The logic. Trained on 2,900 acquisitions since 2012, the model leans on size (small), age, retained earnings, asset growth, volatility and how many deals the sector has just seen. Announcement = the day the stock jumped, not the day the paperwork was filed.
| top 1% | 15.4% acquired within a year |
| next 2% (97-99) | 10.3% acquired within a year |
| next 2% (95-97) | 9.0% acquired within a year |
| next 5% (90-95) | 7.3% acquired within a year |
| next 15% (75-90) ← this stock | 6.4% acquired within a year |
| next 25% (50-75) | 4.8% acquired within a year |
| bottom half | 3.0% acquired within a year |
Why not to buy on it. A takeover paid a median +22% on the day — but even in the top band about 6 in 7 companies are not bought, and those lag. Buying the whole top list returned what the S&P 500 did (2012–2023), and adding "cheap" or "beaten-down" filters did not change that. Read it as context for a thesis you already have, never as the thesis.
How to read a company this small
This is a SPAC (Special Purpose Acquisition Company) or blank-check entity. There's no operating business yet — it's a pool of cash looking for a target to merge with.
- Cash in trust per share — typically $10.00 at IPO, slowly accrues interest
- Sponsor reputation and track record
- Time remaining to find a target (usually 18-24 months)
- Announced target (if any) and the proposed deal structure
- Warrant terms — usually 1/2 to 1/4 warrant per share at $11.50 strike
All operating metrics — there are no operations. Revenue, FCF, EBITDA are all near zero or sponsor expenses.

⚠ Genuine comparables are scarce at this size, so peer multiples are unreliable here. Treat as rough context only — see 📍 What to focus on above.
How does CTAA stack up against its closest peers?
Ideally we compare CTAA only to same-industry peers, but too few exist in our universe right now, so the basket below mixes in broader-sector names. Treat the multiples as rough context, not a valuation.
▾ What's "EV / Sales" in plain English?
EV (Enterprise Value) = market cap + total debt − cash. It's "what you'd pay to buy the entire company outright" — you pay the market cap to shareholders and take over their debt, but you keep their cash. EV is fairer than market cap alone because it includes the debt the new owner inherits.
EV / Sales = EV ÷ annual revenue. So "2.5×" means investors pay $2.50 of enterprise value per $1 of yearly sales. Higher = market is paying more per dollar of sales (usually because they expect future growth or fat margins).
p25 / median / p75 are the 25th, 50th (middle), and 75th percentile of the peers' multiples. Half the peers fall between p25 and p75. The median (p50) is the typical peer — that's the benchmark we compare to.
Bold middle number = median peer. Half the peers trade above it, half below. Computed over 3 peers (broad — see caveat); implausible multiples excluded.
⚠️ Important caveat: peer multiples only work if the peers are genuinely comparable. Always check the peer list below — if the auto-picker grabbed micro-caps or unrelated businesses, the comparison is noise. A medical-device giant priced against tiny biotech startups won't produce a useful signal.
Quality & solvency checks
Cheap stocks can be cheap for a reason. These screens warn when a low valuation comes paired with structural fragility.
Why it matters: Cheap-looking stocks (low P/E or P/B) often have low Z-scores because the market knows the company is dying. Z-score warns you before you fall into a value trap.
Reference: > 3.0 = safe zone · 1.81–3.0 = grey zone · < 1.81 = distress zone
Full explanation →
The Z-score needs working capital, retained earnings, EBIT, sales and total assets from the latest balance sheet, and at least one of those isn't reported in machine-readable form here — common for foreign private issuers. We leave it blank rather than compute a distress verdict from an estimated input. It doesn't affect the reported figures in the financial tables below.
Why it matters: High score = fundamentals improving. Low score = deteriorating. Especially powerful for filtering cheap stocks: cheap + high F-score historically outperforms; cheap + low F-score is often a value trap.
Reference: 7–9 = strong · 4–6 = mediocre · 0–3 = weak
Full explanation →
The F-score compares two consecutive years of income, cash-flow and balance-sheet data. We have 0 years of income data for this filer, but no machine-readable cash-flow statement — so several of the nine checks have no input at all. We show nothing rather than score a partial year against itself. The reported figures in the financial tables below are unaffected.
A standard discounted cash flowDCF — Discounted Cash Flow — sums up all future cash a business will produce, adjusted for the fact that future dollars are worth less than dollars today.
Why it matters: It is the most fundamentally honest valuation method when applicable — but only works for companies with predictable, positive cash flow.
Reference: Best for: mature, profitable businesses. Fails for: pre-profit growth, banks, REITs.
Full explanation → (DCF) valuation is not meaningful for Clearthink 1 Acquisition Corp. because the model projects future cash flows from revenue trajectory, and the company is a SPAC, typically pre-revenue or pre-merger. The model implies no positive equity value under its assumptions, indicating a speculative or low-confidence valuation. Investors are likely betting on a successful business combination. The biggest risk is that the model's underlying assumptions fail to capture the optionality of a SPAC, as the market may be assigning value to a future merger target, which is not in the model.

What you actually need to decide
Every stock price is a disagreement. Here's the single thing that must go right for the bulls, the single thing that breaks the thesis, and the concrete signposts to watch so you can update your view as real results arrive.
- Announcement of a definitive agreement for a business combination
- Shareholder vote on a proposed business combination
- Completion of the de-SPAC transaction and listing of the combined entity

What They Make
Clearthink 1 Acquisition Corp. is a Special Purpose Acquisition Company (SPAC) formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization, or similar business combination with one or more businesses. Investors in the SPAC are the primary payers, providing capital for the eventual acquisition.

Why Is It Priced Like This?
Why Customers Pay
What we use instead: book value (P/B) — computed from the figures this company does report, shown in the sections below. Those numbers are unaffected by the missing cash-flow data.
The market is pricing CTAA based on the expectation of a future business combination, rather than current cash flow, as indicated by the 'FCFFree Cash Flow (FCF) — Operating cash flow minus capital spending: cash left after a company covers operating costs, taxes and interest and reinvests in the business — but BEFORE repaying debt principal or paying dividends. The cash actually available to investors.
Why it matters: A company can show big profits on paper while burning through cash. FCF is what actually fills the bank account.
Reference: Healthy mature businesses convert 8–15% of revenue into FCF · Growth companies often negative
Full explanation → negative: revenue/margin growth model projects future cash flows from revenue trajectory' flag. The market may be assigning value to the potential for a successful merger with an attractive private company, which is not in the model. The current share price of $9.95, close to the typical SPAC IPO price, reflects this pre-merger stage and the speculative nature of its future prospects.
Business Model & Valuation
How They Make Money
As a SPAC, the company primarily funds itself through equity raises from its initial public offering and sponsor capital, with proceeds held in a trust account until a business combination is completed; no dividends or buybacks are typically observed at this stage.
Growth / Revenue DCF
No cash flow statement data available - using revenue/margin growth model as fallback.
Show advanced inputs
| Revenue Growth | 15.0% |
What this model does NOT do: this is a consolidated owner-earnings FCF model. Standalone segment assumptions: none. It does not project net interest income and fee-income lines independently; their combined effect is embedded in the historical revenue and cash-flow trend the model extrapolates. The calculator above can only approximate a segment's impact through the single consolidated growth rate — it cannot model any one line separately. For a true segment-level view, build a separate model from the company's segment disclosures.
Maturity & Competitive Position
Moat Signals
Not available from current data sources, as SPACs typically have limited operating history prior to a business combination.
Geography & Markets
Clearthink 1 Acquisition Corp. is a US-headquartered SPAC, and while it seeks to acquire a business, its geographic focus for potential targets is not specified in current filings. Exact segment split is not in current filings.

Why it matters: When the fast line crosses above the slow line, short-term momentum is turning up; below, turning down. A timing cue, not a value signal.

Technicals describe price, not the business. A great company can have a "bearish" tape (a buying chance) and a weak one a "bullish" tape (a trap). Pair these with the valuation and health sections above.

Guardrail Notes (5)
- FCF negative: revenue/margin growth model projects future cash flows from revenue trajectory.
- INVARIANT: weighted IV is non-positive. Model may not be appropriate.
- Model implies no positive equity value under these assumptions. Valuation is speculative/low-confidence.
- Illiquidity discount 25% applied (small/micro-cap — harder to exit, demand a margin).
- Extreme valuation gap (P/IV withheld — see the note above): result may be dominated by model assumptions, share count issues, or sector-specific dynamics. Treat as low confidence.
