Archimedes Tech SPAC Sponsors III LLC 4

What Happened

• Archimedes Tech SPAC Sponsors III LLC, the issuer's sponsor and a 10% owner, purchased 390,000 private units on January 26, 2026. Each private unit consists of one ordinary share and one‑fourth of a redeemable warrant, so the purchase equals 390,000 ordinary shares and 97,500 whole warrants. The units were bought under a Private Units Purchase Agreement at $10.00 per unit for an aggregate purchase price of $3,900,000. This was a purchase (private placement) rather than a sale.

Key Details

• Transaction date: 2026-01-26; Filing date: 2026-01-26 (no indication of a late filing).
• Purchase: 390,000 private units (1 ordinary share + 1/4 warrant per unit) at $10.00/unit; total = $3,900,000.
• Derivative component: 97,500 warrants (included in the private units) reported as a derivative acquisition.
• Shares/warrants owned after transaction: 390,000 private units (equivalent to 390,000 ordinary shares and 97,500 warrants) as reflected in the filing.
• Footnotes: Units purchased pursuant to a Private Units Purchase Agreement dated Jan 22, 2026.

Context

• The warrants become exercisable the later of 12 months from the IPO closing and 30 days after completion of the issuer's initial business combination, with an exercise price of $11.50 per share and a five‑year post‑combination expiration (subject to adjustments and earlier redemption/liquidation).
• This filing reports an institutional sponsor purchase (a financing/structuring transaction) rather than trading by an individual executive; such sponsor placements are common in SPAC financings and reflect the sponsor taking its customary founder/private units.
