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.
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 fieldsATAK 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.
The score is only published for names that carry both a price and a filed cash-per-share figure — 294 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 filingsRead the full profile
Aurora Technology Acquisition Corp. was a blank-check company that priced its initial public offering on February 7, 2022, under SEC file number 333-261753. Its common stock traded on the Nasdaq Stock Market under the ticker ATAK, and the company was classified under SEC SIC industry code 3841, covering surgical and medical instruments and apparatus. The offering was registered through S-1 filing 0001193125-21-361665, filed on December 20, 2021, with the pricing prospectus filed as 424B4 0001193125-22-029747. The company completed a business combination and ceased filing as a blank-check vehicle, with its change in shell company status reported in 8-K 0001493152-24-007083 filed on February 20, 2024. EDGAR now lists this CIK under the name DIH Holding US, Inc.
Material findings
from the full read of every filingEvery 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.
Senior secured convertible debentures issued at an original issue discount, with monthly redemptions payable in stock, mean the company can service its debt by continuously issuing shares - dilution that compounds every month rather than arriving in one tranche. The debentures are secured, so the lender holds collateral ahead of equity if the stock route fails. Failure to vote counts as a vote against, which the proxy flags directly. The ATAK trust was released at the de-SPAC.
ATAK's units break into three instruments, and two of them are fractional: each unit becomes one Class A share, one warrant and one right, where two warrants buy one Class A share and ten rights deliver one Class A share. A unit holder's real share entitlement is therefore well below the unit count. The sponsor's Class B shares convert one-for-one into Class A immediately before the combination. Up to 6,000,000 Earnout Shares follow over five years on VWAP milestones — 1,000,000 at $12.00, 1,333,333 at $13.50, 1,666,667 at $15.00, and a further tranche of 2,000,000.
The consideration is fixed in dollars and converted at a contractual $10.00 per share, so the share count DIH receives does not move with ATAK's market price. ATAK's units split into one Class A share, one warrant and one right, where two warrants buy one share and ten rights deliver one share — the fractional instruments are where a unit holder's real entitlement is decided. Up to 6,000,000 Earnout Shares follow over five years on VWAP milestones of $12.00 (1,000,000 shares), $13.50 (1,333,333) and $15.00 (1,666,667), with a further tranche of 2,000,000.
An ATAK unit is unusually fractional: it carries one Class A share, one warrant and one right, where two warrants are needed to purchase one Class A share and ten rights to receive one. On top of the base consideration DIH stockholders may receive up to 6,000,000 Earnout Shares over the five years after closing, of which the first tranche of 1,000,000 requires the VWAP of New DIH Class A common stock to equal or exceed $12.00 for any 20 Trading Days. Class B ordinary shares convert one-for-one at the domestication and again into Class A immediately before the combination.
The unit economics dilute in fractions: two ATAK warrants are needed to buy one Class A share and ten rights convert into one Class A share, so the 26,670,000 registered warrants stand for far fewer shares than the count suggests. On top of the base consideration, DIH stockholders may receive up to 6,000,000 Earnout Shares during the five years from the closing, the first 1,000,000 of them if the volume weighted average price reaches or exceeds $12.00 for any 20 trading days in that period. Class B ordinary shares convert one-for-one and then into Class A before the combination.
The unit mechanics dilute in fractions: two ATAK warrants buy one Class A share and ten rights convert into one Class A share, so the 26,670,000 registered warrants stand for far fewer shares than their count suggests, and each unit yields one share, one warrant and one right. Up to 6,000,000 Earnout Shares may follow over the five years from closing, beginning with 1,000,000 if the volume weighted average price reaches or exceeds $12.00 for any 20 trading days and 1,333,333 at the next milestone.

A missing score, not a score of zero — why
A Sponsor Score is only published once the sponsor’s prior vehicles have been verified on EDGAR and their post-close outcomes priced. That record does not exist for this sponsor yet, so no number and no tier is shown. That is a missing score, not a score of zero — and not a neutral 50 either.
Coverage so far: 301 of 1284 tracked SPACs (23%) are attached to a scored sponsor. This card fills in by itself as the research lands.

In plain English
tap a term to open itEvery 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.

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 3841 (Surgical & Medical Instruments & Apparatus).

EDGAR now files this CIK as "DIH HOLDING US, 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.
