### Footnotes:

(1) On September 19, 2025, Lake Harriet Holdings, LLC (?Lake Harriet Holdings?) entered into a prepaid variable share forward contract (the ?Contract?) with an unaffiliated third-party buyer. Lake Harriet Holdings is obligated to deliver to the buyer on the settlement date (the ?Settlement Date?), based on the specified scheduled valuation date of September 21, 2026, at Lake Harriet Holdings? option, either (i) up to 350,000 shares of common stock, par value $0.001 per share (?common stock?), of Terawulf Inc. (the ?Issuer?) (such number of shares, the ?Component Number of Shares?), determined based on the terms of the Contract (as described in footnotes 3, 4 and 5), or (ii) a cash payment equal to the value of such Component Number of Shares, determined based on the terms of the Contract (as described in footnotes 3, 4 and 5).

(2) (Continued from footnote 1) In exchange for assuming this obligation, Lake Harriet Holdings received a cash payment pursuant to the terms of the Contract. Lake Harriet Holdings pledged 350,000 shares of common stock (the ?Pledged Shares?) to secure its obligations under the Contract. Lake Harriet Holdings retains dividend and voting rights in the Pledged Shares during the term of the pledge.

(3) The cash amount or number of shares to be delivered to the buyer on the Settlement Date will be determined on the valuation date. The number of shares or cash amount is determined as follows: (a) if the volume-weighted average price at which the shares of common stock trade on the valuation date (the ?Settlement Price?) is less than or equal to a price specified in the Contract (the ?Forward Floor Price?), Lake Harriet Holdings will deliver to the buyer (i) if Lake Harriet Holdings elects physical settlement, the Component Number of Shares or (ii) if Lake Harriet Holdings elects cash settlement, a cash payment in an amount equal to the value of the Component Number of Shares as of the valuation date;

(4) (Continued from footnote 3) (b) if the Settlement Price is between the Forward Floor Price and a price specified in the Contract (the ?Forward Cap Price?), Lake Harriet Holdings will deliver to the buyer (i) if Lake Harriet Holdings elects physical settlement, a number of shares of common stock equal to the product of (A) the Component Number of Shares and (B) a fraction, the numerator of which is the Forward Floor Price and the denominator of which is the Settlement Price, or (ii) if Lake Harriet Holdings elects cash settlement, a cash payment in an amount equal to the number of shares determined as described in the preceding clause (b)(i);

(5) (Continued from footnote 4) and (c) if the Settlement Price is greater than the Forward Cap Price, Lake Harriet Holdings will deliver to the buyer (i) if Lake Harriet Holdings elects physical settlement, a number of shares of common stock equal to the product of (A) the Component Number of Shares and (B) a fraction, the numerator of which is the sum of (x) the Forward Floor Price and (y) the Settlement Price minus the Forward Cap Price, and the denominator of which is the Settlement Price, or (ii) if Lake Harriet Holdings elects cash settlement, a cash payment in an amount equal to the number of shares determined as described in the preceding clause (c)(i).

(6) By Lake Harriet Holdings The Nazar M. Khan Revocable Trust ("Khan Revocable Trust") is the sole member of Lake Harriet Holdings. The Reporting Person is the sole trustee of the Khan Revocable Trust and may be deemed to have the power to direct the voting and disposition of the Common Stock beneficially owned by the Khan Trust. Accordingly, pursuant to the regulations promulgated under Section 13(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), the Reporting Person may be deemed to be a beneficial owner of the shares of Common Stock held for the account of the Khan Revocable Trust.
