Nelson Daniel D 4

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.

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.
