SpacBrain’s read

Trust settled

The deal closed — SPAC shares became the target's shares, so there is no trust left to redeem (nobody missed a window; holders who wanted cash elected it at the vote).


In plain terms

What it is
A SPAC from Concord Sponsor Group III LLC, listed on NYSE in November 2021.
What it's doing now
It agreed to buy GCT Semiconductor Holding, Inc.. That purchase completed, and it stopped being a SPAC — the shares became shares in the business it bought.
What you should know
This SPAC has finished. The purchase completed, and the shares became shares in the company it bought — anyone who wanted the cash instead asked for it at the vote, so there is no cash left here to claim and no deadline left to miss.

Cash held per sharenot filed for this window

This vehicle has finished, so there is no window to file a cash-per-share figure for and none will follow. No estimate is shown in its place.

Next date that mattersno dated event on file

Nothing dated is on file. That is an absence in the record, not a statement that nothing is coming.

Yield to redemption

Nothing left to redeem — no yield to compute.

This SPAC has finished — its trust was paid back or used to close the deal, so there is nothing left to redeem and no yield to compute. A yield to redemption is a claim that you can hand these shares back for the trust cash. That account is closed, so this page will not print a number here.

The score

deterministic, from filed fields

CNDB is not in the scored universe, so no score is shown. A withheld score is a fact about the record, not a verdict about the company.

Asymmetric return scoreNeither a price nor a cash-per-share figure is on file for this vehicle, and the score is a ratio between the two. Nothing is estimated to fill the gap.

The score is only published for names that carry both a price and a filed cash-per-share figure — 292 of the tracked fleet today. The rest keep an empty dial rather than a modelled one, and fill in by themselves as the fields land.

The company

from SEC filings
Read the full profile

Concord Acquisition Corp III was a blank-check company whose common stock traded on the New York Stock Exchange under the ticker CNDB and was assigned SEC CIK 0001851961 and SIC industry code 3674 (Semiconductors & Related Devices). The company priced its initial public offering on November 5, 2021, pursuant to a 424B prospectus filed under SEC file number 333-254789 and S-1 0001104659-21-042548, with the registrant describing itself as a blank check company in that prospectus. The ticker CNDB appears on the cover page of an 8-K filed on February 29, 2024 (accession 0001104659-24-028838). The vehicle is closed, as established by Form 25 filed on March 27, 2024 (accession 0000876661-24-000235) under 17 CFR 240.12d2-2(a)(3), reflecting that the securities came to evidence other securities in substitution therefor. EDGAR now files CIK 0001851961 under the name GCT Semiconductor Holding, Inc.


Material findings

from the full read of every filing

Every document this company files gets read whole — body and exhibits. These are the ones the read flagged as material, newest first, each citing its filing.

  • The company remains pre-commercial-scale with $50M+ in borrowings and a $52M stockholders' deficit, but has secured cash runway and production capacity through Q1 2027. The expanded ATM signals potential dilution risk, while the $12.3M non-cash warrant liability loss reflects rising stock/warrant prices.

  • The going concern qualification and heavy reliance on ATM equity sales signal the company is burning cash and diluting shareholders aggressively to stay afloat. The $15.4M non-cash warrant liability increase and $30.2M H1 net loss underscore financial deterioration, while the untouched $20M Obsidian facility and repeated related-party debt extensions (Anapass, Kyeongho Lee at penalty rates up to 3%/month) indicate constrained financing alternatives.

  • The third item is the one with economic weight: lifting the 19.99% NYSE ceiling on an equity line converts the facility from a limited backstop into an open-ended source of stock, with the share count set by future prices rather than by any figure in this proxy. Director compensation disclosure shows the stock the board is being paid in has fallen through the year — restricted units valued at $5.21 on June 28, 2024, $3.35 on September 30, 2024 and $2.33 on December 31, 2024 — which is the same trend that makes an uncapped equity line expensive.

  • The consideration is a formula, not a fixed number: the Company Value is $350 million minus GCT's indebtedness at closing, plus its cash and cash equivalents, plus the aggregate exercise price of all in-the-money GCT warrants, and that value is divided by $10.00. So the share count moves with GCT's balance sheet between now and closing. Assuming no Concord III public stockholder exercises conversion rights, GCT's holders are expected to hold about 68.7% of New GCT. A further 20,000,000 earnout shares can be issued on price targets from 60 days after closing to the fifth anniversary.

  • Based on GCT's shares, options, warrants and restricted stock units as of January 30, 2024, the filing expects about 54,860,842 shares to be issued and GCT's holders to hold roughly 68.7% of the combined company immediately after closing, so Concord III's own holders and sponsor take the minority. On top of that sit up to 20,000,000 Earnout Shares, issuable to GCT stockholders and the financing investors if the volume weighted average price meets price targets at any time from 60 days after closing to the fifth anniversary, or on a qualifying change of control.

  • The registered ceiling is stated but the expected outcome is not: the total number of New GCT shares to be issued and the percentage GCT's holders would end up with are both printed as blanks at this version, as is the measurement date for them. What is fixed is the formula — the Company Value is $350 million minus GCT's indebtedness at closing, plus its cash and cash equivalents, plus the aggregate exercise price of its in-the-money warrants, all divided by $10.00 — plus up to 20,000,000 earnout shares on price targets running to the fifth anniversary of closing.

Show 2 more material filings
  • The Company Value is $350 million less GCT's indebtedness, plus its cash and cash equivalents, plus the aggregate exercise price of all its in-the-money warrants, so the consideration moves with the target's balance sheet at closing rather than being fixed. The share count and the ownership split are not stated at this version: the expected number of New GCT shares and the percentage GCT holders would hold are both printed as blanks, and so is the as-of date they would be measured on. Up to 20,000,000 Earnout Shares may follow on price targets running to the fifth anniversary of the Closing.

  • The two numbers a Concord III holder needs are blank at this first version: the total New GCT shares expected to be issued is printed as a blank and the percentage GCT's holders would hold afterwards is printed as a blank percentage, both keyed to an as-of date also left blank. The formula is stated — Company Value divided by $10.00, where Company Value is $350 million less GCT's indebtedness, plus its cash and cash equivalents, plus the aggregate exercise price of its in-the-money warrants — but without GCT's share count it cannot be resolved. Up to 20,000,000 Earnout Shares may follow.


Filings

live EDGAR feed

Everything this company has filed with the SEC recently, newest first, each with a plain summary of what changed and why it matters.

  • What changed: GCT Semiconductor (formerly CNDB SPAC) reported Q2 2026 results: revenue fell 17.9% YoY to $1.0M while net loss widened 50.5% to $20.4M, though 5G chipset shipments rose ~71% sequentially to over 5,100 units. Cash improved to $30.2M from $590K at YE 2025, and the ATM facility was expanded from $75M to $120M within the $200M shelf. Why it matters: The company remains pre-commercial-scale with $50M+ in borrowings and a $52M stockholders' deficit, but has secured cash runway and production capacity through Q1 2027. The expanded ATM signals potential dilution risk, while the $12.3M non-cash warrant liability loss reflects rising stock/warrant prices.

  • What changed: GCT Semiconductor (post-merger entity from CNDB) disclosed substantial going concern doubt with $635.6M accumulated deficit and $30.2M cash, raised $55.7M gross via ATM (cap increased from $75M to $120M in June 2026), and saw warrant liabilities surge from $2.87M to $18.3M driven by fair value remeasurement. Shares outstanding jumped from 58.1M (Dec 2025) to 92.0M (Aug 2026) due to ATM sales and Indigo Note conversions, while stockholders' deficit stood at $52.0M. Why it matters: The going concern qualification and heavy reliance on ATM equity sales signal the company is burning cash and diluting shareholders aggressively to stay afloat. The $15.4M non-cash warrant liability increase and $30.2M H1 net loss underscore financial deterioration, while the untouched $20M Obsidian facility and repeated related-party debt extensions (Anapass, Kyeongho Lee at penalty rates up to 3%/month) indicate constrained financing alternatives.

  • What changed: GCT Semiconductor Holding, Inc., the successor to Concord Acquisition Corp III, called its 2026 annual meeting for September 17, 2026 at 4:00 p.m. Pacific Time by live audiocast with no physical location, record date July 24, 2026. Holders elect two Class II directors to serve until the 2029 annual meeting and ratify BPM LLP as auditor for the fiscal year ending December 31, 2026. Why it matters: Routine annual governance with no trust or redemption right surviving from the Concord III SPAC. The deferral mechanism means director RSUs accumulate off the current share count and settle later on a separation, change of control or death - so the dilution is real but deferred, and a change-of-control event would accelerate delivery of the whole deferred block at once.

  • What changed: GCT Semiconductor Holding, Inc., the Concord Acquisition Corp III successor, filed definitive additional proxy material consisting of a notice-and-access voting card. The captured card is dated to the 2025 annual meeting: it tells holders to vote by 11:59 p.m. ET on September 17, 2025 for a meeting on September 18, 2025 at 4:00 p.m. PDT, with paper or email copies of the annual report, notice and proxy statement available on request before September 4, 2025 via ProxyVote.com, 1-800-579-1639 or sendmaterial@proxyvote.com. Why it matters: Nothing in the card affects a trust, a redemption right or a deadline — it is the mailing instrument rather than a disclosure document. The dates it carries belong to the 2025 meeting even though the filing is dated August 2026, so the card should not be relied on for the current meeting timetable; the definitive proxy statement filed the same day governs. Confidence is low for that reason: the captured text and the filing date disagree about which meeting it serves.(flagged for human review)

In plain English

tap a term to open it

Every piece of jargon this page could have used, and what it actually means.

Open the plain-English guide
No floor / floorlessthe cash guarantee is gone — the price is unprotected

A SPAC's downside protection is not the cash in trust; it is your right to demand that cash. Once the redemption window closes, the cash stays with the company and the share can trade anywhere.

Redemption deadlinethe last day to hand shares back for cash

Set by the filing that calls the meeting. Tender after it and the company is under no obligation to pay you the trust value.

Broker action datethe day your broker needs the instruction — earlier than the official date

Brokers batch redemption instructions to the transfer agent, so the practical cutoff is roughly two business days before the published deadline. This is the date that actually costs people the floor.

Cash in trust / trust per sharethe cash the company is holding for each public share

Filed quarterly in the 10-Q's XBRL. It earns interest between filings, so the figure on a given day is slightly higher than the last filed one — where we show that we label it an estimate.

Trust discountbuying below the cash held for you

Only meaningful while a redemption right exists. On a floorless name the same arithmetic is not a discount, it is the market pricing distress, and this product will not call it a yield.

Dilutionhow much of the company new shares take from you

Sponsor promote, PIPE shares, warrants and rights all issue stock that did not pay $10 for it. The headline deal value is before that; the effective value is after.

Pro-forma equitywhat the company is valued at once the deal closes

The combined company's equity value assuming the announced terms and the redemptions that have actually happened.

ARShow much upside you get per unit of downside

SpacBrain's asymmetric-return score. It is deterministic — the same inputs always produce the same number — and it is capped, not zeroed, when the floor is gone.

De-SPACthe day the SPAC becomes the real company

The shares stop being a claim on a pot of cash and start being equity in an operating business. Roughly 80% of recent de-SPACs traded below $10 within a year.

Outside datethe contractual long-stop for closing the deal

A deadline between the SPAC and its target, not between the SPAC and you. It confers no right to cash, which is exactly why it must never be counted as a redemption window.

Accession numberthe SEC's unique id for one filing

Every figure on this page carries the accession of the filing that states it, so you can open the primary document rather than trust us.

Accreted NAV (estimate)the last filed cash figure, plus the interest it should have earned since

A model, not a filing: last filed value compounded at the 3-month T-bill for the days elapsed. Always shown in italic with the word estimate, and never printed beside a filed number without it.

CNDB — company record
UNIVERSE-IPO-INDEX2026-08-17

admitted from EDGAR's QUARTERLY FORM INDEX, walked without any SIC filter. The SIC 6770 census could not reach this registrant: EDGAR reassigns a shell's SIC the day it stops being one, and this CIK now files under 3674 (Semiconductors & Related Devices). The screen found it by filing SHAPE instead — S-1 2021-03-26 → 8-A12B 2021-11-03 → 424B4 2021-11-05 — which nothing rewrites. Admission rule: src/lib/universe-admit.ts. SIC 3674 + self-described blank check in 424B4 0001104659-21-135144; 424B 0001104659-21-135144 priced 2021-11-05 under S-1 0001104659-21-042548 (file 333-254789, an offering for cash); common ticker CNDB off 10-Q 0001410578-23-002439 (2023-11-14); lifecycle EXITED. The pricing prospectus was filed under SEC file number 333-254789, which belongs to S-1 0001104659-21-042548 (2021-03-26) — a registration of shares sold for CASH, which is what makes it an IPO rather than merger consideration. Blank-check status from the registrant's own first-person sentence in that prospectus (EDGAR full-text search, 424B4 2021-11-05). Ending PROVEN, not inferred: CLOSED per Form 25 0000876661-24-000235 (2024-03-27) — Form 25 filed under 17 CFR 240.12d2-2(a)(3) — the rule for securities that "have come to evidence other securities in substitution therefor", i.e. the shares became the successor's (class: Concord Acquisition Corp III - Units, each consisting of one share of Class A Common Stock and one-half of one Warrant). EDGAR now files this CIK as "GCT Semiconductor Holding, Inc." — the SPAC's own name is kept here and the successor is the target. ipoSizeM and deadline left NULL: gross-proceeds prose conflates the over-allotment with the offering, and a charter deadline belonging to a vehicle that has ended is a date nobody can act on. ipoDate is the 424B pricing date.
