Grayscale Bitcoin Trust ETF - Valuation of Bitcoin and Determination of NAV

The Sponsor will evaluate the Bitcoins held by the Trust and determine the NAV of the Trust in accordance with the relevant provisions of the Trust Documents. The following is a description of the material terms of the Trust Documents as they relate to valuation of the Trust’s Bitcoins and the NAV calculations, which is calculated using non-GAAP methodology and is not used in the Trust’s financial statements.

On each business day at 4:00 p.m., New York time, or as soon thereafter as practicable (the “Evaluation Time”), the Sponsor will evaluate the Bitcoins held by the Trust and calculate and publish the NAV of the Trust. To calculate the NAV, the Sponsor will:

Multiply the Index Price by the Trust’s aggregate number of Bitcoins owned by the Trust as of 4:00 p.m., New York time, on the immediately preceding day, less the aggregate number of Bitcoins payable as the accrued and unpaid Sponsor’s Fee as of 4:00 p.m., New York time, on the immediately preceding day.

Add the U.S. dollar value of Bitcoins, calculated using the Index Price, receivable under pending creation orders, if any, determined by multiplying the number of the Creation Baskets represented by such creation orders by the Basket Amount and then multiplying such product by the Index Price.

Subtract the U.S. dollar value of the Bitcoins, calculated using the Index Price, which are either (i) to be distributed under pending redemption orders, if any, determined by multiplying the number of Baskets to be redeemed represented by such redemption orders by the Basket Amount and then multiplying such product by the Index Price, or (ii) to be distributed to Shareholders pursuant to a binding obligation of the Trust following the declaration of an in-kind dividend (including through interests in any liquidating trust or other vehicle formed to hold such Bitcoins) (the amount derived from steps 1 through 5 above, the “NAV Fee Basis Amount”).

Subtract the U.S. dollar amount of the Sponsor’s Fee that accrues for such business day, as calculated based on the NAV Fee Basis Amount for such business day.

In the event that the Sponsor determines that the primary methodology used to determine the Index Price is not an appropriate basis for valuation of the Trust’s Bitcoins, the Sponsor will utilize the cascading set of rules as described in “-Overview of the Bitcoin Industry and Market-The Index and the Index Price.”

The Sponsor will publish the Index Price, the Trust’s NAV and the NAV per Share on the Trust’s website as soon as practicable after its determination. If the NAV and NAV per Share have been calculated using a price per Bitcoin other than the Index Price for such Evaluation Time, the publication on the Trust’s website will note the valuation methodology used and the price per Bitcoin resulting from such calculation.

In the event of a hard fork of the Bitcoin Network, the Sponsor will, if permitted by the terms of the Trust Agreement, use its discretion to determine, in good faith, which peer-to-peer network, among a group of incompatible forks of the Bitcoin Network, is generally accepted as the network for Bitcoin and should therefore be considered the appropriate network for the Trust’s purposes. The Sponsor will base its determination on a variety of then relevant factors, including (but not limited to) the following: (i) the Sponsor’s beliefs regarding expectations of the core developers of Bitcoin, users, services, businesses, miners and other constituencies and (ii) the actual continued acceptance of, mining power on, and community engagement with the Bitcoin Network.

The shareholders may rely on any evaluation furnished by the Sponsor. The determinations that the Sponsor makes will be made in good faith upon the basis of, and the Sponsor will not be liable for any errors contained in, information reasonably available to it. The Sponsor will not be liable to the Authorized Participants, the shareholders or any other person for errors in judgment. However, the preceding liability exclusion will not protect the Sponsor against any liability resulting from gross negligence, willful misconduct or bad faith in the performance of its duties.
