Stockholders' Equity Note [Abstract]  
Stockholders' Equity Stockholders’ Equity
Authorized Equity
Prior to the Corporate Conversion, we issued two classes of common units to members in the form of Class A voting units (“Class A Units”) and Class B non-voting units (“Class B Units”). Class A Units and Class B Units participated pro-rata, on the basis of total outstanding units, in our ordinary and liquidating distributions. The Company retained the right to repurchase both vested and unvested Class B Units at the original $0.0022 per unit purchase price in the event of a breach of fiduciary duty, fraud, disparagement, or other conduct materially detrimental to the Company, as determined by the Board of Managers. Additionally, we issued the Preferred Units in connection with the Preferred Units Financing. The holders of Preferred Units received a cumulative in-kind dividend at a rate of 15% per annum, compounding annually. Upon the Company’s election, it may satisfy such dividend in cash. Additionally, the holders of the Preferred Units were entitled to receive, on an as-converted basis, the same dividends, as to amount and timing, as any dividends paid by the Company on its common units. The Preferred Units were convertible into the equity securities issued upon an IPO.
Class B Units were subject to vesting provisions: 25% of Class B Units immediately vested on the date of issuance, and the remaining 75% vest in equal monthly installments over five years. Unvested Class B Units did not participate in distributions. See Note 9, Share-Based Compensation for further discussion of Class B Units issued to service providers.
The Corporate Conversion resulted in the elimination of Fermi LLC’s historical members’ equity accounts and the recognition of 567,391,294 shares of common stock at par value of $0.001 and an increase to additional paid-in capital of $193,198. The Company’s authorized capital stock consists of 2,400,000,000 shares of common stock, $0.001 par value per share, of which 629,839,790 shares are issued and outstanding and 10,000,000 shares of preferred stock, $0.001 par value per share, of which no shares are issued and outstanding. The outstanding shares of common stock presented on the consolidated balance sheet exclude 38,412,070 shares of restricted stock units issued under ASC 718 that are compensatory and subject to service-based and performance-based vesting conditions.
In connection with the Corporate Conversion, all issued Class A Units and Class B Units automatically converted, on a 3-for-1 basis, into 483,049,312 and 100,638,450 shares of common stock, respectively. Concurrently, all issued Preferred Units automatically converted into 7,586,546 shares of common stock at a conversion price of $14.36 per share, which reflects a 31.6% discount to the initial offering price of $21.00 (the “Preferred Units Conversion”). On September 23, 2025, we accelerated the vesting of certain Class B Units that were held by certain service providers. The remaining restricted shares issued upon conversion of Class B Units remained subject to the original service-based vesting provision. On December 31, 2025, we accelerated the vesting of all remaining shares of restricted common stock issued originally as Class B Units that were held by service providers.
Equity Transactions
Prior to the Corporate Conversion, we issued 359,261,550 Class A Units for cash contributions of $798. On August 2, 2025, the Company issued 4,500,000 Class A Units to an affiliate of the Company’s Co-Founder, President, and Chief Executive Officer in connection with a compensation arrangement. See Note 9, Share-Based Compensation for further discussion.
Additionally, prior to the Corporate Conversion, we issued 104,716,350 Class B Units for cash contributions of $233. This total includes 12,128,850 Class B Units that were issued during April 2025 in connection with the conversion of an equivalent number of Class A Units, which were subsequently reissued to newly admitted Class B members. In June 2025, the Company repurchased 4,077,900 unvested Class B Units from a service provider following the termination of the service relationship. The units were repurchased at the original purchase price of $0.0022 per unit. In August 2025, the Company repurchased 11,250,000 Class B Units in aggregate from two former service providers following the termination of the service relationships. The units were repurchased by the Company at the original $0.0022. In September 2025, the Company donated the repurchased 11,250,000 Class B Units to Dechomai Asset Trust, an unrelated, third party, 501(c)(3) public nonprofit organization. On September 23, 2025, the Company modified the vesting conditions to accelerate vesting of 16,551,563 Class B Units, which were unvested Class B Units granted to certain employees and service providers, including certain executive officers. See Note 9, Share-Based Compensation for further discussion.
Additionally, in connection with the IPO, we issued and sold 37,375,000 shares of common stock, inclusive of the exercised over-allotment option by the underwriters, for $745,631 in cash, after deducting the underwriting discounts and
commissions. On October 22, 2025, in connection with the MPS Agreement (as defined below) the Company issued 1,190,476 shares of common stock as partial consideration for initial lease prepayments. See Note 8, Leases, for additional details. On December 31, 2025, the Company modified the vesting conditions to accelerate vesting of the remaining 13,996,125 restricted shares of common stock, which were issued from unvested Class B Units granted to certain employees and service providers, including certain executive officers. See Note 9, Share-Based Compensation for further discussion.

Preferred Units Financing – Issuance
Prior to the Corporate Conversion, we issued and sold 322,654,500 Preferred Units for $107,552 in cash. The Company incurred $7,049 of offering costs directly attributable to this issuance, which were recorded as a reduction to additional paid-in capital.
Preferred Units Financing – Founder-granted Options
To incentivize the investors to participate in the Preferred Units Financing, certain founders of the Company granted the investors on August 29, 2025, an aggregate total of 2,868,000 options to purchase Class A Units held by the founders, at a Company valuation of $5,000,000 until June 30, 2026 (the “Preferred Unit Investor Options”). The Company is not a party to these options and as such the options will not exist on the consolidated balance sheet. Consistent with Staff Accounting Bulletin (“SAB”) Topic 5T, because the options were granted by the Company’s founders to facilitate the Preferred Units Financing, the Company recognized a capital contribution from the founders of $39,292, equal to the fair value of the options, with a corresponding reduction to issuance proceeds from investors.
Separately, to induce the conversion of the Series A Convertible Notes and Series B Convertible Note, certain founders granted the noteholders an aggregate total of 1,728,000 options to purchase Class A Units held by the founders with the same terms as the Preferred Unit Investor Options. The Company is not a party to these options and as such the options will not exist on the consolidated balance sheet. Consistent with SAB Topic 5T, because the options were granted by the Company’s founders to facilitate these voluntary conversions, the Company recognized a capital contribution from the founders of $23,674, equal to the fair value of the options, with a corresponding inducement expense recorded to other income (expense), net in the consolidated statement of operations for the period from January 10, 2025 (Inception) through December 31, 2025.
Preferred Units Financing – Embedded Derivative
In connection with the Preferred Units, the Company bifurcated an embedded derivative related to the premium payable upon share-settlement triggered by an IPO. The bifurcated embedded derivative was measured at fair value using Level 3 inputs and was initially recorded at $31,990 on August 29, 2025. After reflecting the capital contribution described above and the bifurcated embedded derivative, the Preferred Units were initially recorded at $35,993, which is net of $277 of deferred offering costs.
Preferred Units Financing – Conversion
Upon the Corporate Conversion on September 30, 2025, the Preferred Units automatically converted into common stock of the Company. As a result, the Company derecognized the Preferred Units and the embedded derivative as of September 30, 2025. Prior to derecognition, the Company accreted preferred dividends of $1,423 on Preferred Units and the Company also recognized a change in fair value of the bifurcated embedded derivative of $46,350, which was recorded as an expense within other income (expense), net in the consolidated statement of operations.
The excess of the fair value of common stock over the carrying values of the Preferred Units and the embedded derivative is a reduction of income available to common stock within the computation of net loss per share. See Note 4, Net Loss Per Share.
The Preferred Units were classified as mezzanine equity during the period because redemption was outside the Company’s control. The Company has not separately presented the activity between August 29, 2025 (the issuance date) and September 30, 2025 (the conversion date) related to the classification of Preferred Units as mezzanine equity within the consolidated statement of stockholders’/members’ equity. Because the Preferred Units were not outstanding at either the beginning or end of any period presented, the Company determined that such presentation would not be meaningful to the users of these consolidated financial statements.
Convertible Notes Conversion
On August 29, 2025, in connection with the issuance of Preferred Units, the Seed Convertible Notes automatically converted into 30,572,796 Class A units pursuant to the original terms. On the same date, the holders of the Series A Convertible Notes and Series B Convertible Note elected to convert their convertible notes into 87,214,966 Class A units, pursuant to the original terms of the notes. The Company accounted for the conversions by derecognizing the carrying amounts of the respective notes and recognizing the issuance of Class A Units for the same amounts.
Governance and Voting Rights
Prior to the Corporate Conversion, the Company was governed by the Board of Managers (the “Pre-Conversion Board”) who was appointed and can be replaced by the affirmative vote of Class A members holding the Requisite Voting Threshold. Each Class A Unit was entitled to one vote. Pre-Conversion Board decisions required the unanimous consent of all managers. The Pre-Conversion Board had three managers, and Class A members could appoint up to three additional managers. The Pre-Conversion Board could not approve certain business decisions without the affirmative vote of Class A members holding the Requisite Voting Threshold. These decisions included raising external capital, issuing dividends, entering fundamental business transactions, and asset purchases above a specified threshold.
Subsequent to the Corporate Conversion, the Company is governed by the board of directors (the “Board”). In connection with the IPO, we entered into a director nomination agreement (the “Director Nomination Agreement”) which resulted in TMNN Manager LLC (“TMNN”) and Caddis Holdings LLC each designating one nominee to the board. The Melissa A. Neugebauer 2020 Trust has elected not to designate a director as of the date that these financial statements were available to be issued and has certified to the Company that it does not intend to do so for the foreseeable future. Our certificate of incorporation (“Charter”) provides that the number of directors on our Board shall be determined by a majority of our board of directors. Our Charter provides that our Board is divided into three classes as nearly equal in size as practicable, designated Class I, Class II and Class III, until the annual meeting of shareholders to be held in 2029, at which time, a phase-in of a declassified Board shall begin. The term of office of the initial Class I, Class II and Class III directors expires at the first, second and third regularly-scheduled annual meetings of the shareholders following December 31, 2025, respectively. Commencing with the annual meeting of shareholders to be held in 2029, directors succeeding those whose terms are then expired shall be elected to hold office for a term expiring at the annual meeting of shareholders held in the year following the year of their election. In addition, the Company established an audit committee and a compensation committee.
Holders of shares of our common stock are entitled to one vote for each share held of record on all matters on which shareholders are entitled to vote generally, including the election or removal of directors. The holders of our common stock do not have cumulative voting rights in the election of directors. Holders of our common stock are entitled to receive dividends when, as, and if declared by our Board out of funds legally available therefore, subject to any statutory or contractual restrictions on the payment of dividends and to any restrictions on the payment of dividends imposed by the terms of any outstanding preferred stock. The Company’s common stock is neither convertible nor redeemable.
