On December 29, 2025, Datavault announced that its board of directors declared a dividend (“Distribution”) of one Dream Bowl Meme Coin II token (such token, the “Meme Coin”) for every 60 shares of the Datavault’s common stock, par value $0.0001 per share (the “Datavault Common Stock”), held or deemed to be held by certain Datavault equityholders for purposes of the Distribution pursuant to certain contractual rights of the holders of the following equity securities of Datavault, in each case as of the close of business on the Record Date (as defined below):

(i)            Datavault Common Stock (“Record Datavault Common Holders”),

(ii)           certain warrants to purchase Datavault Common Stock that have the right to participate in the Distribution pursuant to their respective terms (such warrants, the “Record Datavault Warrants” and such record holders, the “Record Datavault Warrant Holders”),

(iii)          certain convertible promissory notes of Datavault that have the right to participate in the Distribution pursuant to their respective terms (such notes, the “Record Datavault Notes” and such record holders, the “Record Datavault Note Holders”), and

(iv)          certain equity awards and/or grants that are issued and outstanding as of the Record Date and which were granted under Datavault’s stock option plan, stock incentive plan or other equity incentive plans that have not been exercised or converted and settled (or, in the case of restricted stock awards, that have not yet vested) as of the Record Date that are entitled to participate in the Distribution pursuant to the terms of their respective awards and/or grants (such awards or grants, the “Record Datavault Awards” and such record holders, the “Record Datavault Award Holders” and together with the Record Datavault Common Holders, the Record Datavault Warrant Holders, and the Record Datavault Note Holders, the “Record Holders”).

The preceding Datavault securities held by the Record Holders as of the Record Date are collectively referred to herein as the “Datavault Securities”.

A:

If you are a Record Holder, meaning you held Datavault Securities as of the close of business on the Record Date, you are entitled to receive Meme Coins, subject to your having:

(i)            a digital wallet with Datavault into which Meme Coins can be delivered on or after the Payment Date; and

(ii)           elected to receive the Distribution by completing, duly executing, and submitting an Opt-In Agreement to Alliance Advisors, Datavault’s Information Agent (the “Information Agent”), in which, among other things, you will be required to provide a valid and accurate Datavault digital wallet address for Datavault to transfer the Meme Coins.

If you do not already have a digital wallet with Datavault, instructions on how to set up a digital wallet with Datavault can be found at www.dreambowlcoin2.com.

You may initiate your election to receive your portion of the Distribution by completing, executing and submitting the Opt-In Agreement, which can be accessed at www.dreambowlcoin2.com. Once you have printed and executed the Opt-In Agreement you will need to upload the completed and executed agreement via a secure link on the Distribution Website under the field “Upload Your Opt-In Agreement”.

If you are a Datavault Record Common Holder, then you will receive one Meme Coin for every 60 shares of Datavault Common Stock held (or underlying the applicable Datavault Securities held) by you as of the close of business on the Record Date.

If you are a Record Datavault Warrant Holder, Record Datavault Note Holder or Record Datavault Award Holder, you will receive one Meme Coin for every 60 shares of Datavault Common Stock underlying the applicable Datavault Securities held by you as of the close of business on the Record Date, as determined pursuant to the terms of the applicable Datavault Security you hold.

If you are a Record Holder and hold (a) fewer than 60 shares of Common Stock (or shares of Common Stock underlying the applicable Datavault Securities held) as of the Record Date, you will not be entitled to receive any Meme Coins or (b) more than 60 shares of Common Stock (or shares of Common Stock underlying the applicable Datavault Securities held) as of the Record Date in increments of other than 60 shares, you will be entitled to receive only such number of Meme Coins as is determined by dividing the number of shares of Common Stock (or shares of Common Stock underlying the applicable Datavault Securities held) held by you as of the Record Date by 60 (rounding down to the nearest increment of 60 shares). By way of example, if you hold 125 shares of Common Stock as of the Record Date, you will only be entitled to receive two Meme Coins (i.e., one Meme Coin in respect of each 60 shares of Common Stock (or shares of Common Stock underlying the applicable Datavault Securities held) held as of the Record Date).

Yes. In the cover letter that was mailed by Datavault, there is a QR Code that you may scan to obtain access to the Distribution Website (defined below) hosted by Datavault’s Information Agent, Alliance Advisors, where you can obtain a copy of the Distribution Materials and instructions on how to complete and submit your Opt-In Agreement and, if you don’t already have one, set up a digital wallet with Datavault.

You must initiate the process of electing to receive your portion of the Distribution by setting up your digital wallet with Datavault (unless you already have one) and completing the Opt-In Agreement by navigating to the Distribution Website at www.dreambowlcoin2.com. On the Distribution Website, you can view and download the Distribution Materials, set up a digital wallet with Datavault, and print, complete and submit your Opt-In Agreement.

The Meme Coins are a digital asset and can only be held in a digital wallet. It is a condition to the receipt of the Meme Coins in the Distribution that you have a digital wallet hosted by Datavault.

If you don’t already have a digital wallet with Datavault, instructions for opening a digital wallet with Datavault can be found on the Distribution Website at www.dreambowlcoin2.com.

Execution of the Opt-In Agreement is also a condition to the receipt of the Meme Coins.

By executing an Opt-In Agreement, you are agreeing, among other things, to the payment conditions set forth therein, and acknowledging that you understand the process for receiving the Meme Coins, that the Datavault Board can change the Record Date, Payment Date or revoke the Distribution, and that the Meme Coins may not have or maintain any value.

If you hold your shares in “street name” through a brokerage firm, bank, dealer or other similar organization, then in connection with your execution and delivery of the Opt-In Agreement, (a) Datavault may require additional documentation to verify the number of shares of Datavault Common Stock you hold, including the delivery of a copy of your brokerage statement as of the Record Date (or a full monthly statement for January 2025) or other certification regarding your holdings of Datavault Common Stock as of the Record Date, (b) you will need to authorize Datavault and Alliance Advisors to contact your brokerage firm, bank, dealer or other similar organization for purposes of verifying your holdings, and (c) you will be required to indemnify Datavault and its directors, officers, stockholders, members, partners, employees and agents to the fullest extent permitted by law with respect to certain losses arising in connection with your participation in the Distribution, including any inaccuracy in the number of shares of Datavault Common Stock set forth in your Opt-In Agreement, as more fully described therein. Verification of the number of shares of Datavault Common Stock that you hold shall be in the sole discretion of Alliance Advisors based on the certifications and/or other records and information presented by the applicable Record Holder.

Datavault urges you to read carefully the Opt-In Agreement prior to making any decision to accept the Meme Coins.

Datavault will notify holders of Meme Coins when they can commence trading the Meme Coins on the Information Data Exchange.

Trades of Meme Coins made on the Information Data Exchange will incur ordinary course trading fees that are based on transaction value and embedded within the terms of the applicable smart contract. Meme Coins that are exported to and traded on other trading platforms or digital exchanges may be subject to additional fees not imposed by Datavault.

Record Datavault Common Holders and Record Datavault Award Holders

The distribution of Meme Coins is an in-kind distribution that may be a dividend (to the extent of Datavault’s current and accumulated earnings and profits (“E&P”)). With respect to Meme Coins issued to a Record Datavault Common Holder or Record Datavault Award Holder, any amount in excess of E&P would reduce a Record Datavault Common Holder or Record Datavault Award Holder’s tax basis in its Datavault Common Stock underlying the dividend and any amount in excess of that basis should constitute gain. Datavault may elect to treat the entire amount as a dividend or may elect to report it in another manner as it decides is appropriate in consultation with Datavault’s tax preparers. In executing and delivering to Datavault the Opt-In Agreement, you agree (and will be required absent disclosure to the Internal Revenue Service (the “IRS”) and other tax authorities) to report such amounts in the same manner as Datavault.

Datavault intends to notify such record holders of the manner in which it will report such amounts to the IRS by push notifications to digital wallets.

Record Datavault Warrant Holders

The tax treatment of the dividend with respect to the Record Datavault Warrant Holders of the Meme Coin is unclear. Such distribution could be treated as an adjustment to conversion price and a dividend, or may be subject to another treatment. Datavault will report such amounts in such manner as it decides is appropriate in consultation with Datavault’s tax preparers. In executing and delivering to Datavault the Opt-In Agreement, you agree (and will be required absent disclosure to the IRS and other tax authorities) to report such amounts in the same manner as Datavault.

Datavault intends to notify such record holders of the manner in which it will report such amounts to the IRS by push notifications to digital wallets.

Datavault has adopted a procedure called “householding”. Under this procedure, Datavault delivers a single copy of the letter from Datavault to multiple stockholders and other equityholders who share the same address, unless it has received contrary instructions from one or more of such stockholders or other equityholders. This procedure reduces our printing costs, mailing costs and fees. Stockholders and other equityholders who participate in householding will continue to be able to access and receive separate letters from Datavault. Upon written or oral request, Datavault (through the Information Agent) will deliver promptly a separate copy of the letter from Datavault to any stockholder or other equityholder at a shared address to which Datavault delivered a single copy of any of these materials. To receive a separate copy, or, if a stockholder or other equityholder is receiving multiple copies, to request that we only send a single copy of the letter from Datavault, such stockholder or other equityholder may contact Alliance Advisors at:

Alliance Advisors

Telephone Number: 1-888-244-0512 (or 1-551-367-1997 for international holders)

Email Address: DVLT2@allianceadvisors.com

We encourage stockholders to contact Alliance by telephone or e-mail instead of physical mail to help ensure timely receipt of any request a copy of the letter from Datavault.

There may be legal and tax consequences from your election to participate in the Distribution, execution of the Opt-In Agreement and receipt of the Distribution.

Datavault encourages all Record Holders to seek legal and tax advice from qualified legal counsel and a tax professional before deciding to elect to participate in the Distribution, execute the Opt-In Agreement and receive the Distribution.
