BlockchAIn (AIB) Director Nelson Daniel Receives 40,708 Shares/Options

What Happened

  • Nelson Daniel, a director of BlockchAIn Digital Infrastructure, Inc. (AIB), was granted/acquired a total of 40,708 securities on March 16, 2026 as part of the closing of a business combination. This breaks down to 40,444 common shares (37,527 + 2,917) and 264 derivative option interests (59 + 10 + 195).
  • The filing notes the common-share portion results from conversion of Signing Day Sports, Inc. (SGN) holdings under the Business Combination Agreement (see footnote F1). Using BlockchAIn’s first reported post-closing price of $4.60 (reported March 17, 2026), the converted common shares are worth roughly $186,042 (40,444 × $4.60). The derivative interests are options assumed/converted from SGN and carry exercise prices of $1,594.17 (for the 59- and 10-share options) and $1,157.06 (for the 195-share option) per footnotes F3–F5.

Key Details

  • Transaction date: March 16, 2026; Form 4 filed March 18, 2026 (timely filing).
  • Transaction type/code: A = grant/award/other acquisition (conversion under a Business Combination Agreement).
  • Shares/options received: 37,527 and 2,917 common shares; 59, 10, and 195 option interests (total 40,708).
  • Estimated market value (common shares only): ≈ $186,042 based on $4.60/share (first reported BlockchAIn trade, Mar 17, 2026).
  • Options details: Converted employee options assumed by BlockchAIn and converted into options to purchase 59, 10 and 195 common shares (exercise prices in footnotes F3–F5).
  • Ownership after transaction: Not specified in the provided excerpt of the filing.
  • Notable footnotes: F1 explains conversion ratio (0.09334 BlockchAIn shares per SGN share) and pre-/post-closing prices; F2 notes Mr. Nelson is co-trustee of The Nelson Revocable Living Trust and disclaims beneficial ownership except for his pecuniary interest.

Context

  • These were conversion/assumption transactions resulting from a corporate business combination (SPAC/merger mechanics), not open-market buys or sales. The derivative items are options converted into BlockchAIn options (not exercised/sold in this filing).
  • The exercise prices reported for the converted options ($1,157.06 and $1,594.17) are far above the initial post-closing market price ($4.60), so those options are currently out‑of‑the‑money based on the cited price.
  • Such conversion/award entries are typically routine corporate restructuring outcomes and do not necessarily signal a director’s buy/sell sentiment.
