Description of Organization and Business Operations [Abstract]
DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS	NOTE 1. DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS *Organization and General* Colombier Acquisition Corp. III (the “Company”) is a blank check company incorporated as a Cayman Islands exempted company on August 15, 2025. The Company was incorporated for the purpose of effecting a merger, amalgamation, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (the “Business Combination”). The Company may pursue an initial Business Combination target in any industry. As of March 31, 2026, the Company had not entered into a definitive agreement with any specific Business Combination target. As of March 31, 2026, the Company had not commenced any operations. All activity for the period from August 15, 2025 (inception) through March 31, 2026 related to the Company’s formation, the Initial Public Offering (as defined below), and subsequent to the Initial Public Offering, identifying and evaluating prospective acquisition candidates and activities in connection with the Business Combination. The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. Following the Initial Public Offering, the Company generates non-operating income in the form of interest income from the proceeds derived from the Initial Public Offering, which are held in the Trust Account (as defined below). The Company has selected December 31 as its fiscal year end. *Initial Public Offering* The Company’s sponsor is Colombier Sponsor III LLC (the “Sponsor”). The Registration Statement on Form S-1 for the Initial Public Offering, initially filed with the U.S. Securities and Exchange Commission (the “SEC”) on October 17, 2025 (File No. 333-290932), was declared effective on January 30, 2026 (as amended, the “IPO Registration Statement”). On February 5, 2026, the Company consummated the initial public offering of 29,900,000 units (the “Public Units”) at $10.00 per Public Unit, which included the full exercise of the Over-Allotment Option (as defined in Note 6) in the amount of 3,900,000 units (the “Option Units”) at $10.00 per Option Unit, generating gross proceeds of $299,000,000 (the “Initial Public Offering”), which is described in Note 3. Each Public Unit consists of one Class A ordinary share, par value $0.0001 per share, of the Company (the “Class A Ordinary Shares” and with respect to the Class A Ordinary Shares included in the Public Units, the “Public Shares”) and one-eighth of one redeemable warrant (each, a “Public Warrant”). Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of 150,000 units (the “Private Placement Units” and together with the Public Units, the “Units”) at a price of $10.00 per Private Placement Unit, in a private placement to the Sponsor, generating gross proceeds of $1,500,000 (the “Private Placement”), which is described in Note 4. Each Private Placement Unit consists of one Class A Ordinary Share (the “Private Placement Shares”) and one-eighth of one redeemable warrant (the “Private Placement Warrants” and together with the Public Warrants, the “Warrants”). Each whole Warrant entitles the holder to purchase one Class A Ordinary Share at a price of $11.50 per share, subject to adjustment. Transaction costs amounted to $4,379,406, consisting of the Deferred Fee of up to $3,000,000 (as defined in Note 6), and $1,379,406 of other offering costs. *The Trust Account* Following the closing of the Initial Public Offering, on February 5, 2026, an amount of $299,000,000 ($10.00 per Unit) from the net proceeds of the Initial Public Offering and the Private Placement was placed in a trust account located in the United States (the “Trust Account”), with Continental Stock Transfer & Trust Company (“Continental”), acting as trustee. The funds are initially invested only in U.S. Department of Treasury obligations with a maturity of one hundred eighty-five (185) days or less or in money market funds that meet certain conditions under Rule 2a-7 under the Investment Company Act of 1940, as amended (the “Investment Company Act”) and that invest only in direct U.S. government obligations. The holding of these assets in this form is intended to be temporary and for the sole purpose of facilitating the intended Business Combination and, may at any time be held as cash or cash items, including in demand deposit accounts at a bank. Funds will remain in the Trust Account until the earlier of (i) the consummation of the Business Combination or (ii) the distribution of the Trust Account proceeds as described below. The remaining proceeds outside the Trust Account may be used to pay for business, legal and accounting due diligence on prospective acquisitions and continuing general and administrative expenses. The Company’s amended and restated memorandum and articles of association (the “Amended and Restated Articles”) provide that, other than the Permitted Withdrawals (as defined below), if any, none of the funds held in the Trust Account will be released until the earlier of (i) the completion of the Business Combination; (ii) the redemption of any Public Shares that have been properly submitted in connection with a shareholder vote to approve an amendment to the Amended and Restated Articles (A) in a manner that would affect the substance or timing of its obligation to redeem 100% of the Public Shares if it does not complete a Business Combination by February 5, 2028, 24 months from the closing of the Public Offering (or by May 5, 2028, 27 months from the closing of the Initial Public Offering if the Company has executed a letter of intent, agreement in principle or definitive agreement for a Business Combination by February 5, 2025) (“Combination Period”) or (B) with respect to any other provision relating to the rights of holders of the Public Shares (the “Public Shareholders”) or pre-Business Combination activity; and (iii) the redemption of 100% of the Public Shares if the Company is unable to complete a Business Combination within the Combination Period. The proceeds deposited in the Trust Account could become subject to the claims of the Company’s creditors, if any, which could have priority over the claims of the Public Shareholders. *Business Combination* The Company’s management (“Management”) has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering, although substantially all of the net proceeds of the Initial Public Offering are intended to be generally applied toward consummating an Business Combination. The Business Combination must occur with one or more target businesses that together have an aggregate fair market value of at least 80% of the assets held in the Trust Account (excluding the Deferred Fee and taxes paid or payable on income earned on the Trust Account, if any) at the time of the agreement to enter into the Business Combination. Furthermore, there is no assurance that the Company will be able to successfully effect a Business Combination. The Company, after signing a definitive agreement for a Business Combination, will either (i) seek shareholder approval of the Business Combination at a meeting called for such purpose in connection with which Public Shareholders may seek to redeem their Public Shares, regardless of whether they vote for or against the Business Combination, for cash equal to their pro rata share of the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the Business Combination, including interest earned on the funds held in the Trust Account (net of amounts withdrawn to fund working capital requirements, subject to a limit of the greater of $1,000,000 and 10% of the interest earned on the Trust Account per fiscal year ending on December 31, and to pay taxes, if any (“Permitted Withdrawals”)), (ii) provide Public Shareholders with the opportunity to sell their Public Shares to the Company by means of a tender offer (and thereby avoid the need for a shareholder vote) for an amount in cash equal to their pro rata share of the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the Business Combination (which was $10.02 per Public Share as of March 31, 2026), including interest less Permitted Withdrawals. The decision as to whether the Company will seek shareholder approval of the Business Combination or will allow shareholders to sell their Public Shares in a tender offer will be made by the Company, solely in its discretion, and will be based on a variety of factors such as the timing of the transaction and whether the terms of the transaction would otherwise require the Company to seek shareholder approval, unless a vote is required by law or under the rules of the New York Stock Exchange. Pursuant to the Amended and Restated Articles of Association if the Company is unable to complete the Business Combination within the Combination Period, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible, but no more than ten business days thereafter subject to lawfully available funds therefor, redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account including interest earned (which interest shall be net of Permitted Withdrawals and up to $100,000 of interest to pay dissolution expenses and net of taxes payable, if any), divided by the number of then outstanding Public Shares, which redemption will completely extinguish the Public Shareholders’ rights as shareholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining shareholders and the Company’s board of directors (“Board”), dissolve and liquidate, subject in each case to the Company’s obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. The Sponsor, and the Company’s officers and directors have entered into a letter agreement with the Company, dated February 3, 2026 (the “Letter Agreement”), pursuant to which, among other things, they are entitled to rights to liquidating distributions from the Trust Account with respect to any Founder Shares (as defined in Note 5) held by them if the Company fails to complete the Business Combination within the Combination Period. However, if the Sponsor and/or Management acquires Public Shares in or after the Initial Public Offering, they will be entitled to liquidating distributions from the Trust Account with respect to such Public Shares if the Company fails to complete the Business Combination within the Combination Period. In the event of a liquidation, dissolution or winding up of the Company after a Business Combination, the Company’s shareholders are entitled to share ratably in all assets remaining available for distribution after payment of liabilities and after provision is made for each class of shares, if any, having preference over the Ordinary Shares. The Company’s shareholders have no preemptive or other subscription rights. There are no sinking fund provisions applicable to the Ordinary Shares, except that the Company will provide its Public Shareholders with the opportunity to redeem its Public Shares for cash equal to their pro rata share of the aggregate amount then on deposit in the Trust Account, upon the completion of the Business Combination, subject to the limitations described herein. *Risks and Uncertainties* The Company’s ability to complete an initial Business Combination may be adversely affected by various factors, many of which are beyond the Company’s control. The Company’s ability to consummate an initial Business Combination could be impacted by, among other things, changes in laws or regulations, downturns in the financial markets or in economic conditions, inflation, fluctuations in interest rates, increases in tariffs, supply chain disruptions, declines in consumer confidence and spending, public health considerations, and geopolitical instability, such as the military conflicts in Ukraine, between the United States, Israel and Iran and others in the Middle East, and Southwest Asia or other armed hostilities. The Company cannot at this time predict the likelihood of one or more of the above events, their duration or magnitude or the extent to which they may negatively impact the Company’s ability to complete an initial Business Combination. *Liquidity and Capital Resources* As of March 31, 2026, we had marketable securities held in the Trust Account of $300,572,506. We may withdraw interest from the Trust Account to pay taxes, if any. We intend to use substantially all of the funds held in the Trust Account, including any amounts representing interest earned on the Trust Account (less income taxes payable, if any), to complete our Business Combination. To the extent that our share capital or debt is used, in whole or in part, as consideration to complete our Business Combination, the remaining proceeds held in the Trust Account will be used as working capital to finance the operations of the target business or businesses, make other acquisitions and pursue our growth strategies. As of March 31, 2026, we had cash of $237,175. We use the funds held outside the Trust Account primarily to identify and evaluate target businesses, perform business due diligence on prospective target businesses, travel to and from the offices, plants or similar locations of prospective target businesses or their representatives or owners, review corporate documents and material agreements of prospective target businesses, and structure, negotiate and complete a Business Combination. In order to fund working capital deficiencies or finance transaction costs in connection with a Business Combination, the Sponsor, or certain of our officers and directors or their affiliates may, but are not obligated to, loan us funds as may be required (such loans, “Working Capital Loans”). If we complete a Business Combination, we intend to repay such Working Capital Loans. In the event that a Business Combination does not close, the Company may use a portion of the working capital held outside the Trust Account to repay such Working Capital Loans, but no proceeds from our Trust Account will be used for such repayment. Up to $1,500,000 of such Working Capital Loans may be converted into warrants of the post-Business Combination entity at a price of $1.50 per warrant. Such warrants would be identical to the Private Placement Warrants. As of March 31, 2026 and December 31, 2025, we did not have any borrowings under any Working Capital Loans. Additionally, to fund working capital, the Company has permitted withdrawals subject to a limit of the greater of $1,000,000 and 10% of the interest earned on the trust account per fiscal year ending on December 31. These permitted withdrawals are limited to only the interest available that has been earned in excess of the initial deposit at the Initial Public Offering. For the three months ended March 31, 2026, the Company did not withdraw any amounts from the Trust Account for working capital purposes and $1,000,000 available for withdraw. In connection with the Company’s assessment of going concern considerations in accordance with ASC 205-40, “Going Concern,” as of this filing, the Company has sufficient funds for the working capital needs of the Company until a minimum of one year from the date of these financial statements. The Company cannot assure that its plans to consummate an initial Business Combination will be successful.

The Company’s sponsor is Colombier Sponsor III LLC (the “Sponsor”).

The Registration Statement on Form S-1 for the Initial Public Offering, initially filed with the U.S. Securities and Exchange Commission (the “SEC”) on October 17, 2025 (File No. 333-290932), was declared effective on January 30, 2026 (as amended, the “IPO Registration Statement”).

Each whole Warrant entitles the holder to purchase one Class A Ordinary Share at a price of $11.50 per share, subject to adjustment.

Transaction costs amounted to $4,379,406, consisting of the Deferred Fee of up to $3,000,000 (as defined in Note 6), and $1,379,406 of other offering costs.

The Trust Account

Following the closing of the Initial Public Offering, on February 5, 2026, an amount of $299,000,000 ($10.00 per Unit) from the net proceeds of the Initial Public Offering and the Private Placement was placed in a trust account located in the United States (the “Trust Account”), with Continental Stock Transfer & Trust Company (“Continental”), acting as trustee. The funds are initially invested only in U.S. Department of Treasury obligations with a maturity of one hundred eighty-five (185) days or less or in money market funds that meet certain conditions under Rule 2a-7 under the Investment Company Act of 1940, as amended (the “Investment Company Act”) and that invest only in direct U.S. government obligations. The holding of these assets in this form is intended to be temporary and for the sole purpose of facilitating the intended Business Combination and, may at any time be held as cash or cash items, including in demand deposit accounts at a bank. Funds will remain in the Trust Account until the earlier of (i) the consummation of the Business Combination or (ii) the distribution of the Trust Account proceeds as described below. The remaining proceeds outside the Trust Account may be used to pay for business, legal and accounting due diligence on prospective acquisitions and continuing general and administrative expenses.

The Company’s amended and restated memorandum and articles of association (the “Amended and Restated Articles”) provide that, other than the Permitted Withdrawals (as defined below), if any, none of the funds held in the Trust Account will be released until the earlier of (i) the completion of the Business Combination; (ii) the redemption of any Public Shares that have been properly submitted in connection with a shareholder vote to approve an amendment to the Amended and Restated Articles (A) in a manner that would affect the substance or timing of its obligation to redeem 100% of the Public Shares if it does not complete a Business Combination by February 5, 2028, 24 months from the closing of the Public Offering (or by May 5, 2028, 27 months from the closing of the Initial Public Offering if the Company has executed a letter of intent, agreement in principle or definitive agreement for a Business Combination by February 5, 2025) (“Combination Period”) or (B) with respect to any other provision relating to the rights of holders of the Public Shares (the “Public Shareholders”) or pre-Business Combination activity; and (iii) the redemption of 100% of the Public Shares if the Company is unable to complete a Business Combination within the Combination Period. The proceeds deposited in the Trust Account could become subject to the claims of the Company’s creditors, if any, which could have priority over the claims of the Public Shareholders.

Business Combination

The Company’s management (“Management”) has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering, although substantially all of the net proceeds of the Initial Public Offering are intended to be generally applied toward consummating an Business Combination. The Business Combination must occur with one or more target businesses that together have an aggregate fair market value of at least 80% of the assets held in the Trust Account (excluding the Deferred Fee and taxes paid or payable on income earned on the Trust Account, if any) at the time of the agreement to enter into the Business Combination. Furthermore, there is no assurance that the Company will be able to successfully effect a Business Combination.

The Company, after signing a definitive agreement for a Business Combination, will either (i) seek shareholder approval of the Business Combination at a meeting called for such purpose in connection with which Public Shareholders may seek to redeem their Public Shares, regardless of whether they vote for or against the Business Combination, for cash equal to their pro rata share of the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the Business Combination, including interest earned on the funds held in the Trust Account (net of amounts withdrawn to fund working capital requirements, subject to a limit of the greater of $1,000,000 and 10% of the interest earned on the Trust Account per fiscal year ending on December 31, and to pay taxes, if any (“Permitted Withdrawals”)), (ii) provide Public Shareholders with the opportunity to sell their Public Shares to the Company by means of a tender offer (and thereby avoid the need for a shareholder vote) for an amount in cash equal to their pro rata share of the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the Business Combination (which was $10.02 per Public Share as of March 31, 2026), including interest less Permitted Withdrawals. The decision as to whether the Company will seek shareholder approval of the Business Combination or will allow shareholders to sell their Public Shares in a tender offer will be made by the Company, solely in its discretion, and will be based on a variety of factors such as the timing of the transaction and whether the terms of the transaction would otherwise require the Company to seek shareholder approval, unless a vote is required by law or under the rules of the New York Stock Exchange.

Pursuant to the Amended and Restated Articles of Association if the Company is unable to complete the Business Combination within the Combination Period, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible, but no more than ten business days thereafter subject to lawfully available funds therefor, redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account including interest earned (which interest shall be net of Permitted Withdrawals and up to $100,000 of interest to pay dissolution expenses and net of taxes payable, if any), divided by the number of then outstanding Public Shares, which redemption will completely extinguish the Public Shareholders’ rights as shareholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining shareholders and the Company’s board of directors (“Board”), dissolve and liquidate, subject in each case to the Company’s obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. The Sponsor, and the Company’s officers and directors have entered into a letter agreement with the Company, dated February 3, 2026 (the “Letter Agreement”), pursuant to which, among other things, they are entitled to rights to liquidating distributions from the Trust Account with respect to any Founder Shares (as defined in Note 5) held by them if the Company fails to complete the Business Combination within the Combination Period. However, if the Sponsor and/or Management acquires Public Shares in or after the Initial Public Offering, they will be entitled to liquidating distributions from the Trust Account with respect to such Public Shares if the Company fails to complete the Business Combination within the Combination Period.

In the event of a liquidation, dissolution or winding up of the Company after a Business Combination, the Company’s shareholders are entitled to share ratably in all assets remaining available for distribution after payment of liabilities and after provision is made for each class of shares, if any, having preference over the Ordinary Shares. The Company’s shareholders have no preemptive or other subscription rights. There are no sinking fund provisions applicable to the Ordinary Shares, except that the Company will provide its Public Shareholders with the opportunity to redeem its Public Shares for cash equal to their pro rata share of the aggregate amount then on deposit in the Trust Account, upon the completion of the Business Combination, subject to the limitations described herein.

Risks and Uncertainties

The Company’s ability to complete an initial Business Combination may be adversely affected by various factors, many of which are beyond the Company’s control. The Company’s ability to consummate an initial Business Combination could be impacted by, among other things, changes in laws or regulations, downturns in the financial markets or in economic conditions, inflation, fluctuations in interest rates, increases in tariffs, supply chain disruptions, declines in consumer confidence and spending, public health considerations, and geopolitical instability, such as the military conflicts in Ukraine, between the United States, Israel and Iran and others in the Middle East, and Southwest Asia or other armed hostilities. The Company cannot at this time predict the likelihood of one or more of the above events, their duration or magnitude or the extent to which they may negatively impact the Company’s ability to complete an initial Business Combination.

Liquidity and Capital Resources

As of March 31, 2026, we had marketable securities held in the Trust Account of $300,572,506. We may withdraw interest from the Trust Account to pay taxes, if any. We intend to use substantially all of the funds held in the Trust Account, including any amounts representing interest earned on the Trust Account (less income taxes payable, if any), to complete our Business Combination. To the extent that our share capital or debt is used, in whole or in part, as consideration to complete our Business Combination, the remaining proceeds held in the Trust Account will be used as working capital to finance the operations of the target business or businesses, make other acquisitions and pursue our growth strategies.

As of March 31, 2026, we had cash of $237,175. We use the funds held outside the Trust Account primarily to identify and evaluate target businesses, perform business due diligence on prospective target businesses, travel to and from the offices, plants or similar locations of prospective target businesses or their representatives or owners, review corporate documents and material agreements of prospective target businesses, and structure, negotiate and complete a Business Combination.

In order to fund working capital deficiencies or finance transaction costs in connection with a Business Combination, the Sponsor, or certain of our officers and directors or their affiliates may, but are not obligated to, loan us funds as may be required (such loans, “Working Capital Loans”). If we complete a Business Combination, we intend to repay such Working Capital Loans. In the event that a Business Combination does not close, the Company may use a portion of the working capital held outside the Trust Account to repay such Working Capital Loans, but no proceeds from our Trust Account will be used for such repayment. Up to $1,500,000 of such Working Capital Loans may be converted into warrants of the post-Business Combination entity at a price of $1.50 per warrant. Such warrants would be identical to the Private Placement Warrants. As of March 31, 2026 and December 31, 2025, we did not have any borrowings under any Working Capital Loans.

Additionally, to fund working capital, the Company has permitted withdrawals subject to a limit of the greater of $1,000,000 and 10% of the interest earned on the trust account per fiscal year ending on December 31. These permitted withdrawals are limited to only the interest available that has been earned in excess of the initial deposit at the Initial Public Offering. For the three months ended March 31, 2026, the Company did not withdraw any amounts from the Trust Account for working capital purposes and $1,000,000 available for withdraw.

In connection with the Company’s assessment of going concern considerations in accordance with ASC 205-40, “Going Concern,” as of this filing, the Company has sufficient funds for the working capital needs of the Company until a minimum of one year from the date of these financial statements. The Company cannot assure that its plans to consummate an initial Business Combination will be successful.
