Overview Regarding Special Meeting of Stockholders to be Held on May 3, 2023

As previously announced, Integral Acquisition Corporation 1 (the “Company”) has called and provided a notice of a special meeting (the “Special Meeting”) to be held on May 3, 2023, at 9:00 a.m. Eastern time, as a virtual meeting, to consider and vote upon the matters described in the Company’s definitive proxy statement filed with the Securities and Exchange Commission on April 13, 2023 (as may be amended, the “Proxy Statement”), including, without limitation, a proposal to extend the date by which the Company must consummate an initial business combination from May 5, 2023 to November 3, 2023 or such earlier date as determined by the Company’s board of directors (the “Extension”).

The Company plans to continue to solicit proxies from stockholders during the period prior to the Special Meeting. Only the holders of the Company’s common stock as of the close of business on March 24, 2023, the record date for the Special Meeting, are entitled to vote at the Special Meeting.

Additional Sponsor Assurances

As previously disclosed in a press release by the Company issued on April 19, 2023 (the “Press Release”), Integral Sponsor LLC intends to support the Company in the wake of a new potential excise tax that may be levied on stockholder redemptions beginning in 2023.

As previously disclosed in the Proxy Statement and the Press Release, on August 16, 2022, the Inflation Reduction Act of 2022 (the “IR Act”) was signed into federal law. The IR Act provides for, among other things, a new U.S. federal 1% excise tax (the “Excise Tax”) on certain repurchases of stock by publicly traded U.S. domestic corporations occurring on or after January 1, 2023. The Excise Tax is imposed on the repurchasing corporation itself, not its stockholders from which shares are repurchased. The amount of the Excise Tax is generally 1% of the fair market value of the shares repurchased. However, for purposes of calculating the Excise Tax, repurchasing corporations are permitted to net the fair market value of certain new stock issuances against the fair market value of stock repurchases during the same taxable year. In addition, certain exceptions apply to the Excise Tax, including for repurchases that occur in the same taxable year as the liquidation of the corporation. The U.S. Department of the Treasury (the “Treasury”) has been given authority to provide regulations and other guidance to carry out and prevent the abuse or avoidance of the Excise Tax. Any share redemption or other share repurchase that occurs after December 31, 2022, in connection with the Extension or otherwise, may be subject to the Excise Tax. Whether and to what extent the Company would be subject to the Excise Tax in connection with the Extension or otherwise will depend on a number of factors, including (i) the fair market value of the redemptions and repurchases in connection with the extension or otherwise, (ii) the nature and amount of any equity issuances issued within the same taxable year of any such redemptions or repurchases, and (iii) the content of regulations and other guidance from the Treasury. In addition, because the Excise Tax would be payable by the Company and not by the redeeming holder, the mechanics of any required payment of the Excise Tax have not been determined.

For the avoidance of doubt, the proceeds placed in the Company’s trust account for the benefit of the holders of the Company’s Public Shares (as defined in the Proxy Statement) and the interest earned thereon shall not be used to pay for any Excise Tax in connection with any redemptions of the Company’s Public Shares prior to or in connection with an extension or its initial business combination.
