On September 2, Blue Acquisition Corp. filed an 8-K running two paragraphs of substance. The Cayman-registered SPAC, its target Blockfusion USA, and the holding company that would list them had signed a Fifth Amendment to their business combination agreement. The change: move the Outside Date to November 30, 2026.

The original agreement was signed on November 19, 2025. That is 287 days and five amendments to a deal the November investor presentation said would close in the first half of 2026.

What is being bought

Blockfusion runs a data center in Niagara Falls, New York, built on a retired coal site with cheap hydro power next door. It spent its first years as a bitcoin mine and had a rough one in 2022, when the city let a mining moratorium lapse into a zoning ordinance and ordered the Frontier Avenue site to stop hashing that October. The company now pitches itself as an AI and high-performance compute landlord instead.

The November 2025 deck put Blockfusion's pre-money equity value at $450 million and pro forma enterprise value at $594.1 million, on 75.0 million shares priced at $10.00. It showed 50 MW energized out of 106 MW at the site, mining revenue of $3 million in 2026 before the wind-down, and HPC revenue reaching $98 million by 2028 and $160 million by 2030. The 2028 number is nearly all forecast. The deck assumes at least one long-term colocation lease by year two without naming a signed one.

The amendment ledger

Each amendment is its own 8-K, and read in sequence they are more informative than any of the press releases.

  • First, March 19, 2026 — post-closing incentive plan raised from 5% to 8% of shares outstanding at closing; board expanded from seven seats to nine.
  • Second, May 6, 2026 — incentive plan raised again, 8% to 12%; listing exchange requirements amended; Outside Date extended.
  • Third, June 30, 2026 — an earnout added for up to 9,250,000 Pubco Class A shares to Blockfusion stockholders on price thresholds over 36 months; board cut back from nine seats to seven.
  • Fourth, July 31, 2026 — Outside Date extended.
  • Fifth, September 2, 2026 — Outside Date extended to November 30, 2026.

Three of the five moved the deadline. Two of the five moved the share pool, in the same direction both times. A 12% incentive plan on roughly 75 million pro forma shares is about 9 million shares, on top of an earnout that can print 9.25 million more. The deal being negotiated in September is not the one announced in November.

What the trust actually holds

Blue's IPO closed on June 16, 2025 and put $201,250,000 into a Continental-held trust against 20,125,000 public shares. The 10-Q for the quarter ended June 30, 2026 shows that trust at $209,286,528, or $10.40 per public share. Treasury interest has been the SPAC's only real income.

BACC closed at $10.49 on September 2. The market is paying nine cents over a trust balance that keeps compounding, which prices the AI data center story at roughly nothing. Public shareholders can redeem for their share of the trust when the merger goes to a vote, and that right is what the price is tracking.

The $33 million tell

The June 30 press release said Blue "expects to enter into a non-redemption agreement for approximately $33 million of the funds held in Blue's trust account." The trust holds $209 million. Arranging to keep $33 million of it is a public estimate of how much survives the redemption vote — about one dollar in six. The same release announced a $175 million convertible note term sheet, non-binding, conditioned on the anchor lease actually being executed.

Two filings worth reading closely

The June 30 anchor-lease announcement is the strongest news the deal has produced: a letter of intent with an unnamed AI customer for up to 300 MW at Niagara Falls, anchored by 85 MW of take-or-pay capacity on a 15-year term, which Blockfusion values at roughly $2.8 billion of lease revenue, or $5.4 billion with both renewal options. The LOI is non-binding except on confidentiality, exclusivity and governing law. Every number in it rests on definitive leases that have not been signed.

The copy of that release filed with the SEC as Exhibit 99.1 opens with a line above the headline: "DRAFT — PRIVILEGED & CONFIDENTIAL — FOR DISCUSSION PURPOSES — SUBJECT TO REVIEW AND APPROVAL." Two weeks later, on July 13, Blue filed an 8-K/A saying it had "inadvertently filed an incorrect copy of the Third Amendment" and attached the right one.

The clock behind the clock

The Outside Date is a private deadline between the parties, and they can keep moving it. The one they cannot move sits in Blue's articles: complete a business combination by March 16, 2027, 21 months after the IPO closed, or redeem all public shares and wind up. Blue's registration statement on Form S-4 was first filed on December 8, 2025 and amended three times — February 9, May 1 and June 30. It has not gone effective, so the proxy has not been mailed and no vote has been scheduled.

Blue's auditors flagged substantial doubt about the company as a going concern. As of June 30 it held $201,861 in operating cash against a working capital deficit of $1,971,934, with $7,043,750 of deferred underwriting fees waiting at closing and an accumulated deficit of $9,016,468. The sponsor may extend working capital loans and has no obligation to. Trust money cannot be touched for any of it.

How to read a SPAC extension if you hold the shares

  • Separate the two deadlines. An Outside Date extension is a contract amendment between the SPAC and its target. The charter deadline is the one that forces liquidation, and for Blue that is March 16, 2027.
  • Price against trust, not against the pitch. Trust per share was $10.40 at June 30 and grows with Treasury yield. Any premium above it is what the market pays for the deal closing.
  • Read what else the amendment touched. Deadline changes travel with economics. Two of Blue's five amendments moved the incentive pool from 5% to 12%.
  • Check the rights separately. BACCR converts to one-tenth of a share on closing, valued in the 10-Q at $0.23 per right. Rights receive nothing from the trust in a liquidation.
  • Count the non-binding language. The anchor lease, the $175 million notes and the non-redemption agreement are all term sheets or letters of intent.

Sponsors bought 7,069,913 founder shares for $25,000. At the current trust value those shares mark near $73 million if the deal closes and near zero if it does not, which is the whole reason extension amendments exist. That asymmetry is a normal feature of the structure rather than a scandal.

The deadline slipping is the least interesting fact in the September 2 filing. SPACs miss Outside Dates constantly and the fix is a one-page amendment. What matters is the pattern underneath: a target whose contracted revenue is still a letter of intent, financing that turns on that letter, a registration statement that has been in review for nine months, and management economics that grew from 5% to 12% across the same stretch. Blockfusion may well build the campus it describes. The site is real and Niagara Falls has the power to run it. Someone holding BACC at $10.49 today is not being paid to find out. The trust is, and it pays $10.40.
