During the fiscal year ended May 31, 2025, the Company closed on four offerings of the Series E Redeemable Preferred Stock (the “Series E Preferred Stock”). The Company sold total shares of 301,673 for proceeds of $6.9 million net of issuance costs of $0.6 million. The Series E Preferred Stock offering was terminated on August 9, 2024.

The shares of Series E Preferred Stock have no voting or conversion rights. Holders of the Series E Preferred Stock are entitled to receive cumulative dividends at a fixed rate of 9.0% per annum. Dividends are calculated based on a 360-day year, declared and accrued monthly, and payable at the discretion of the Board of Directors out of legally available funds. Dividends must be fully paid for all past periods before any distributions can be made to common stockholders or any junior series of equity securities. During the fiscal years ended May 31, 2026 and May 31, 2025, the Company declared and paid approximately $655,000 and $610,000, respectively, of dividends related to Series E Preferred Stock as presented on the consolidated statement of operations.

The Series E Preferred Stock ranks senior to all classes of common stock and junior to all existing and future debt of the Company. Additionally, it is on parity with any future series of preferred stock with substantially identical terms but may rank junior to any future series of preferred stock if the holders of such series are entitled to rights and preferences with priority over the holders of the Series E Preferred Stock. In the event of liquidation, holders are entitled to receive $25.00 per share (the “Series E Stated Value”) plus any accrued but unpaid dividends before any distributions are made to common stockholders. The Series E Preferred Stock has no stated maturity and remains outstanding indefinitely unless redeemed or repurchased by the Company.

Holders may require the Company to redeem any portion of their Series E Preferred Stock at any time for a "Settlement Amount" calculated as the Series E Stated Value plus any unpaid dividends, less a Holder Optional Redemption Fee, equal to a percentage of the Series E Stated Value based on the year when the redemption occurs as follows: 9.00% prior to the first anniversary of the respective tranche closing date (the "Original Issuance Date"); 7.00% on or after the first anniversary but prior to the second anniversary of the Original Issuance Date; 5.00% on or after the second anniversary but prior to the third anniversary of the Original Issuance Date: and 0.00% on or after the third anniversary of the Original Issuance Date. The Settlement Amount can be settled in cash or shares of common stock, subject to a share cap, which limits the total shares deliverable upon redemption to 19.99% of the common stock outstanding prior to the Series E Preferred Stock offering (25,475,751 shares, the “Share Cap”). Any portion of the Settlement Amount exceeding the Share Cap will be settled in cash.

The Company may also redeem shares of Series E Preferred Stock after the second anniversary of the original issuance date, with a minimum notice of 10 days, at the Company Optional Redemption Settlement Amount, which is equal to the Series E Stated Value per share plus any unpaid and accrued dividends. If the Company elects to pay the redemption amount in shares, then the number of shares to be delivered will be calculated as the Company Optional Redemption Settlement Amount divided by the closing price per share of the common stock on the date of the Company Optional Redemption exercise, subject to the Share Cap. During the fiscal year ended May 31, 2026, 25,000 shares of Series E Preferred Stock were redeemed.

On September 23, 2024, the Company entered into a dealer manager agreement for the offering of up to 62,500 shares of Series E-1 Redeemable Preferred Stock, par value $0.001 per share (“Series E-1 Preferred Stock”), at a price per share of $1,000 (the “Series E-1 Stated Value”). During the fiscal year ended May 31, 2025, the Company closed on eight offerings in which the Company issued 62,500 shares for gross proceeds of $62.5 million. The Series E-1 Preferred Stock offering was completed as of May 31, 2025.

The shares of Series E-1 Preferred Stock have no voting or conversion rights. Holders of the Series E-1 Preferred Stock are entitled to receive cumulative dividends at a fixed rate of 9.0% per annum of the Series E-1 Stated Value. Dividends are calculated based on a 360-day year, declared and accrued monthly, and payable at the discretion of the Board of Directors out of legally available funds. Dividends on the shares of Series E-1 Preferred Stock must be fully paid for all past periods before any distributions can be made to common stockholders or any junior series of equity securities. During the fiscal years ended May 31, 2026 and May 31, 2025, the Company declared and paid approximately $5.6 million and $1.7 million, respectively, of dividends related to Series E-1 Preferred Stock as presented on the consolidated statement of operations.

The Series E-1 Preferred Stock ranks senior to all classes or series of common stock and junior to all existing and future debt of the Company. Additionally, the Series E-1 Preferred Stock is on parity with the Series E Preferred Stock and any future series of preferred stock with substantially identical terms but may rank junior to any future series of preferred stock if the holders of such series are entitled to rights and preferences with priority over the holders of the Series E-1 Preferred Stock. In the event of liquidation, holders of the Series E-1 Preferred Stock and holders of shares of any other class or

series of capital stock ranking senior to or on a parity with the Series E-1 Preferred Stock, are entitled to receive an amount per share equal to the Series E-1 Stated Value plus an amount per share that is issuable as a result of any accrued but unpaid dividends before any distributions are made to common stockholders. The Series E-1 Preferred Stock has no stated maturity and remains outstanding indefinitely unless redeemed or repurchased by the Company.

Holders may require the Company to redeem any portion of their Series E-1 Preferred Stock at any time for a "Settlement Amount" calculated as the Series E-1 Stated Value plus any unpaid dividends, less a Holder Optional Redemption Fee equal to a percentage of the Series E-1 Stated Value based on the year when the redemption occurs as follows: 9.00% prior to the first anniversary of the respective tranche closing date (the "Original Issuance Date"); 7.00% on or after the first anniversary but prior to the second anniversary of the Original Issuance Date; 5.00% on or after the second anniversary but prior to the third anniversary of the Original Issuance Date: and 0.00% on or after the third anniversary of the Original Issuance Date. The Settlement Amount can be settled in cash or shares of common stock at the sole option of the Company, subject to a share cap (if required by Nasdaq rules and regulations), which limits the total shares deliverable upon redemption to 19.99% of the common stock outstanding immediately prior to the Series E-1 Preferred Stock offering (25,889,470 shares, the “Share Cap”), unless approval by the Company’s stockholders is obtained to exceed the Share Cap. Any portion of the Settlement Amount exceeding this cap will be settled in cash. Holders may not redeem any shares of Series E-1 Preferred Stock for common stock prior to the first anniversary of the Original Issuance Date.

The Company may also redeem shares of the Series E-1 Preferred Stock after the second anniversary of the Original Issuance Date, with a minimum notice of 10 days, at a redemption price equal to the Series E-1 Stated Value plus any accrued but unpaid dividends. If the Company elects to pay the redemption amount in shares, then the number of shares to be delivered will be calculated as the Settlement Amount divided by the closing price per share of the common stock on the last trading day prior to the date upon which notice was provided to the holder, subject to the Share Cap, if applicable. During the fiscal year ended May 31, 2026, 576 shares of Series E-1 Preferred Stock were redeemed.

On April 30, 2025, the Company entered into the Preferred Equity Purchase Agreement (the “PEPA”) with certain investors for the issuance and sale of up to 156,000 shares of Series G Convertible Preferred Stock (the “Series G Preferred Stock”) in a transaction (the “Private Placement”) pursuant to an exemption from registration under Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”). The shares of the Series G Preferred Stock may be put to the investors from time to time at the Company’s discretion during the period commencing on April 30, 2025 (the “Commitment Date”) and terminating on the earlier of (i) the 36-month anniversary of the Commitment Date or (ii) such date as there ceases to be a sufficient number of authorized but unissued shares of common stock remaining under the Exchange Cap (as defined in the PEPA).

The Series G Preferred Stock became convertible on June 3, 2025, the Registration Effective Date (as defined in the PEPA). Pursuant to the PEPA, the Company filed a registration statement with the SEC, registering the resale of the shares of common stock issuable upon the conversion of the shares of Series G Preferred Stock, on June 3, 2025, as amended by the post-effective amendments filed with the SEC on September 23, 2025 and November 12, 2025, each of which was automatically effective upon filing. Conversion of the Series G Preferred Stock is subject to a customary 4.99% beneficial ownership limitation, as well as a 19.99% conversion limitation pursuant to the applicable Nasdaq Listing Rules (the “Exchange Cap”).

The Series G Preferred Stock ranks senior to all classes of common stock and junior to all existing and future debt of the Company. Upon any dissolution, liquidation or winding up, whether voluntary or involuntary, holders of the Series G Preferred Stock will be entitled to receive distributions out of the assets of the Company in an amount per share equal to the then-current Series G Preferred Stock stated value, whether capital or surplus, before any distributions are made on any shares of the Company's common stock. The Series G Preferred Stock is on parity with the Series E Preferred Stock, Series E-1 Preferred Stock and any future series of preferred stock with substantially identical terms.

Holders have the right to require the Company to redeem the Series G Preferred Stock under certain conditions, such as a Trading Failure, as defined in the Series G Preferred Stock certificate of designation. If there is a Trading Failure, the redemption price is the greater of the Series G Preferred Stock stated value or the product of the lowest conversion price during the period beginning on the date immediately preceding the Trading Failure and ending on the date the holder

If any Investor is prevented from converting any portion of its Series G Preferred Stock because of the Exchange Cap, and such limitation continues for 18 months following the date that is 18 months following the issuance of such Series G Preferred Stock, or, if earlier, the date that is 36 months following the Commitment Date, then the portion of the Series G Preferred Stock held by such Investor at such time shall be redeemed by the Company, within 10 trading days after such earlier date, at a price equal to 110% of the stated value of such Series G Preferred Stock.

On each conversion date, the conversion price for the Series G Preferred Stock being converted (the “Conversion Price”) will equal the greater of (i) 95% of the lowest daily Volume Weighted Average Price for each of the five trading days immediately preceding the conversion date and (ii) the initial floor price of $4.25, which may be reduced by the Company at any time in its sole discretion, but in no event below $1.34 (as may be adjusted from time to time, the “Floor Price”). Based on its initial stated value of $1,000 per share and the $4.25 initial Floor Price, each share of Series G Preferred Stock would be convertible into an aggregate of 236 shares of common stock.

On August 14, 2025, the Company entered into the first amendment (the “First Amendment”) to the PEPA to, among other things, (i) increase the aggregate commitment amount of the shares of Series G Preferred Stock from $150 million to $300 million, and (ii) increase its access to capital by removing the Put Limitation (as defined in the PEPA) that had previously limited the aggregate purchase price for any Put Issuance (as defined in the PEPA) to no more than $75 million. In connection with the First Amendment, on August 14, 2025, the Company filed an amendment (the “First CoD Amendment”) to the Series G Certificate of Designation, originally filed with the Secretary of State of the State of Nevada on April 30, 2025.

The Floor Price sets the minimum floor for the conversion price of the Series G Preferred Stock, which price may not be reduced unless the Company determines to do so in its discretion. The First CoD Amendment further amended the status of converted or repurchased preferred stock such that any shares of Series G Preferred Stock that have been or will be converted will be retired and resume the status of authorized but unissued shares.

In addition, on October 14, 2025, the Company filed a fourth amendment (the “Fourth CoD Amendment”) to the Series G Certificate of Designation, as amended. The Fourth CoD Amendment amended the Series G Certificate of Designation, as amended, to increase the Floor Price (as set forth in Section 1.5(c)(i) of the Certificate of Designation) to $34.00 from $22.00.

On October 21, 2025, the Company entered into the fourth amendment (the “Fourth Amendment”) to the PEPA to, among other things: (i) increase the aggregate commitment amount of the shares of Series G Preferred Stock, from $590.0 million to $1.59 billion; (ii) subject to waiver by a majority-in-interest of the investors, (a) set the maximum put issuance amount to $75.0 million per issuance, (b) set the limit to one put issuance per seven (7) business day period, and (c) set the maximum aggregate stated value of Series G Preferred Stock outstanding at any one time to $75.0 million; (iii) increase the

In addition, under the Fifth CoD Amendment, the Company’s Board of Directors may increase or decrease the applicable Floor Price with respect to any put, at its sole discretion.

On May 29, 2026, the Company entered into the fifth amendment (the “Fifth Amendment”) to the PEPA.

As Series G Preferred Stock may be reissued, during the fiscal years ended May 31, 2026 and May 31, 2025, the Company issued and sold 835,800 and 78,000 shares of Series G Preferred Stock, respectively, for gross proceeds of $815.0 million and $75.0 million, respectively. During the fiscal year ended May 31, 2026, 913,800 shares of Series G Preferred Stock were converted into 51.0 million shares of the Company’s common stock. As of May 31, 2026, no shares of Series G Preferred Stock were issued and outstanding.

The preferred units accrue dividends at a rate of 12.75% per annum, which accrue daily and compound semi-annually, and which, if not redeemed by then, will increase by 87.5 basis points on each of October 7, 2030 and October 7, 2031, and by 200 basis points on October 7, 2035 and each one-year anniversary thereof, up to a maximum rate of 16.75%. The dividend rate will be further increased (i) by the amount that the weighted average all-in annual interest rate on certain indebtedness exceeds 8.75% per annum for so long as such indebtedness is outstanding and (ii) for so long as certain significant events of default or other “trigger events” under the A&R LLCA remain uncured, by 200 basis points per annum. Subject to limited exceptions, the dividends are payable (i) from the initial closing through October 6, 2035, at TopCo 2’s election, either in cash or in kind, and (ii) after October 6, 2035, in cash only.

Additionally, the preferred units carry a minimum 1.80x multiple of invested capital liquidation preference, inclusive of the value of the common units; provided, that (x) in connection with an initial public offering or a drag-along sale in which the sellers receive highly liquid securities, the minimum multiple of invested capital increases to 2.00x and (y) with respect to any additional equity contributions with respect to the Polaris Forge 1 (other than pursuant to the additional closings under the A&R UPA), the then applicable minimum multiple of invested capital will be reduced by an amount that reflects the time between when MIP HPC Holdings, LLC first committed to make the investment and when the actual contribution is made, calculated as interest at a fixed annual rate of 12.75%, accruing daily, on the amount of such additional equity contribution for such period.

The preferred units and the common units are redeemable after April 6, 2028, in exchange for: (i) from April 6, 2028 up to October 6, 2029, the sum of (x) the applicable minimum multiple of invested capital, plus (y) 120% of the fair market value of such common unit(s); (ii) from October 6, 2029 up to October 6, 2030, the sum of (x) the applicable minimum multiple of invested capital, plus (y) 112.5% of the fair market value of such common unit(s); and (iii) from and after October 6, 2030, the greater of (x) the accreted amount, plus any accrued and unpaid dividend, plus the fair market value of such common units, plus certain indemnity payments by TopCo 2 for breaches of business representations of the TopCo 2 under the A&R UPA, if any, and (y) the applicable multiple of invested capital minus certain indemnity payments by the

If the preferred units and common units are outstanding on October 6, 2032, or if certain trigger events occurs and are not cured within specified time periods, MIP HPC Holdings, LLC may require TopCo 2 to commence a customary marketed sale process managed by an independent investment bank, where the proceeds of any such sale are to be used to redeem the preferred units and the common units on the terms set forth above.

Distributions of available excess cash will be made in accordance with a multi-tiered waterfall, generally as follows: (i) first, to MIP HPC Holdings, LLC, to pay certain specified losses under the A&R UPA, if any; (ii) second, to MIP HPC Holdings, LLC, to pay any accrued but unpaid dividends on its preferred units; (iii) third, to the MIP HPC Holdings, LLC, until it has received its Liquidation Preference Amount; and (iv) fourth, to the holders of common units, pro rata in accordance with the number of common units held by them.

The preferred units and corresponding common units were determined to have embedded derivative features, the Redemption features and the Contingent Dividend Rate Increase feature, requiring bifurcation and remeasurement at fair value at each reporting date, with the changes in fair value recorded through earnings. The Redemption features are inclusive of the Investor put option upon a Sale, APLD Holdings call option, and the Distribution Redemptions (all as defined within the A&R UPA). The Company engaged a third party valuation specialist in determining the value of the embedded derivatives using a binomial lattice model, which includes Level 3 unobservable inputs. See Note 10 - Derivative Assets for further details. As the noncontrolling interest has embedded features that require bifurcation, the fair value at issuance was allocated between the components. As such, the net proceeds were first allocated to the derivatives at their fair value. The remainder of the proceeds were then allocated to the warrants and noncontrolling interests based on their relative fair values.

The balance sheets and operating activities of TopCo 2 are included in the Company's consolidated financial statements. The Company adjusts net income in the consolidated statements of operations to exclude the proportionate share of results that is attributable to the noncontrolling interest. Additionally, the Company presents the proportionate share that is attributable to the noncontrolling interest as temporary equity within the consolidated balance sheets. This temporary equity presentation is the result of the noncontrolling interest being subject to certain redemption rights that are not entirely within the Company's control. Due to these redemption rights, at each balance sheet date, the Company is required to adjust the carrying value of the derivatives to fair value and record any changes in fair value within earnings. The Company will adjust noncontrolling interest for the attribution of net income (loss) and preferred dividends of TopCo 2 to the noncontrolling interest holder.
