Notes to Condensed Consolidated Financial Statements

(Amounts in thousands, except share and per share data)

1. Description of Business

Organization and Business

Ionetix Corporation (the “Company” or “Ionetix”) is a cyclotron technology platform company providing full-service radioisotope production and end-to-end radiopharmaceutical manufacturing solutions. With its proprietary compact superconducting cyclotron technology, the Company manufactures short-lived diagnostic radioisotopes used in positron emission tomography imaging. The Company also manufactures therapeutic radioisotopes for targeted alpha therapy (“TAT”), an emerging cancer therapy utilizing alpha radionuclides. TAT delivers high-energy alpha particles to cancer cells and the tumor microenvironment to treat cancer while preserving healthy tissue.

The Company was incorporated in the state of Delaware on December 28, 2009, and maintains its principal office in Lansing, Michigan.

Merger

On April 9, 2026, the Company entered into an agreement and plan of merger and reorganization (the "Merger Agreement") with JDEV Acquisition Corp. ("JDEV"), and JDEV Merger Subsidiary, Inc., a wholly-owned subsidiary of JDEV ("Merger Sub"), pursuant to which Merger Sub will merge with and into the Company, with the Company surviving as a wholly-owned subsidiary of JDEV (the "Merger"). As further discussed in Note 17, Subsequent Events, the Merger closed on April 9, 2026.

Liquidity

The Company has incurred net losses from operations since inception, including $6.9 million and $2.4 million for the three months ended March 31, 2026 and 2025, respectively, and has an accumulated deficit of $193.5 million as of March 31, 2026. The Company has $282 in cash and restricted cash as of March 31, 2026.

On April 9, 2026, the Company completed the Merger described in Note 17, Subsequent Events. In connection with the closing of the Merger, the Company raised $29.7 million in net proceeds from a private placement financing, after deducting placement agent fees and commissions. The Company expects to fund its projected operating requirements through a combination of existing cash, the net proceeds from the private placement financing described above, anticipated revenues from its products and services, and additional financing activities.

The Company expects to continue to incur losses and negative cash flows for the foreseeable future as it continues to invest in research and development, manufacturing, sales and marketing efforts, and site deployment activities to support the growth of its business. If the Company does not perform in line with its operating plan, its capital resources may be depleted more rapidly than expected, and the Company may need to obtain additional financing sooner than anticipated. There can be no assurance that such financing will be available on acceptable terms, or at all.

These conditions raise substantial doubt about the Company’s ability to continue as a going concern for one year from the date these condensed consolidated financial statements are issued. The condensed consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

2. Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”) for interim financial information and include the accounts of the Company and its wholly owned subsidiary. All intercompany balances and transactions have been eliminated in consolidation.

In the opinion of management, the accompanying unaudited condensed financial statements include all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation of the financial position, results of operations and cash flows for the periods presented. The results of operations for the interim periods are not necessarily indicative of the results that may be expected for the full fiscal year or any future period.

Significant Accounting Policies

The Company’s significant accounting policies, including the recent accounting pronouncements adopted and recently issued accounting standards not yet adopted, are described in Note 2 of the “Basis of Presentation and Summary of Significant Accounting Policies” to the audited consolidated financial statements as of and for the fiscal years ended December 31, 2025 and 2024, included as Exhibit 99.1 to the Company’s Current Report on Form 8-K filed with the Securities and Exchange Commission on April 16, 2026. There have been no material changes to these policies during the three months ended March 31, 2026.

Segment Reporting

The Company operates as a single operating and reportable segment. The Company’s Chief Operating Decision Maker (“CODM”) is its Chief Executive Officer, who reviews financial information presented on a consolidated basis for purposes of financial performance review and allocation of resources. Net loss is the primary measure of segment profit or loss that the CODM reviews when assessing consolidated performance. Revenue from customers and significant segment expenses are presented in the Company's condensed consolidated statements of operations. The CODM does not evaluate segment performance using balance sheet information. All of the Company’s long-lived assets and revenue are concentrated in the United States.

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the amounts reported and disclosed in the Company’s condensed consolidated financial statements and accompanying notes. The Company regularly evaluates estimates and assumptions including, but not limited to determination of allowance for credit losses, valuation of inventory, valuation and estimated useful life long-lived assets, valuation of SAFE liability, valuation of derivative liability, valuation of common stock and preferred stock warrants, stock-based compensation, the incremental borrowing rate applied to leases, and income tax related estimates. Actual results could differ materially from those estimates.

Deferred Transaction Costs

Deferred transaction costs consist of legal, accounting, placement agent fees, and other direct and incremental costs incurred in connection with the Company's reverse recapitalization transaction. Such costs are deferred and capitalized until the completion of the transaction, at which time they will be recorded as additional paid-in capital. In the event the transaction is not completed, the deferred transaction costs would be expensed in the period the transaction is determined to be no longer probable.

F-7

Ionetix Corporation

Notes to Condensed Consolidated Financial Statements

(Amounts in thousands, except share and per share data)

During the three months ended March 31, 2026, the Company incurred $906 of transaction costs related to the reverse recapitalization, which were capitalized and included within other non-current assets on the condensed consolidated balance sheets as of March 31, 2026. No transaction costs were incurred during the three months ended March 31, 2025.

Significant Customers

The following table summarizes customers that accounted for 10% or more of revenue or accounts receivable:

	Revenue						Accounts Receivable
	Three Months Ended March 31,						As of March 31,			As of December 31,
	2026			2025			2026			2025
Customer A		36	%		10	%		20	%		20	%
Customer B		25	%		14	%		53	%		49	%
Customer C		18	%		*			14	%		18	%
Customer D		17	%		*			10	%		11	%
Customer E		*			62	%		*			*

* Represents less than 10%

Accounts Receivable, Net

Accounts receivable are stated net of an allowance for credit losses. The following table summarizes accounts receivable, net (in thousands):

	March 31, 2026		December 31, 2025
Gross accounts receivable	$	1,329	$	3,382
Allowance for credit losses		—		(2,129	)
Accounts receivable, net	$	1,329	$	1,253

The allowance for credit losses is estimated using historical collection experience, the aging of receivables, customer-specific information, current economic conditions, and management's expectations regarding collectability. Receivables sharing similar risk characteristics are evaluated collectively, while receivables exhibiting specific credit risk indicators are evaluated individually.

No provision for credit losses was recognized during the three months ended March 31, 2026 or March 31, 2025.

Revenue Recognition

The Company recognizes revenue when control of goods or services is transferred to customers in an amount that reflects the consideration to which the Company expects to be entitled. Revenue is recognized either at a point in time or over time depending on the nature of the performance obligation.

F-8

Ionetix Corporation

Notes to Condensed Consolidated Financial Statements

(Amounts in thousands, except share and per share data)

The Company generates revenues primarily from (i) diagnostic drug and medical radioisotopes sales, (ii) cyclotron system sales (including installation, acceptance and spare parts), and (iii) consulting services and system support services.

The following table presents revenue disaggregated by major product and service lines for the three months ended March 31, 2026 and 2025:

	Three Months Ended March 31,
	2026		2025
Diagnostic drug and medical radioisotopes sales	$	1,071	$	990
Cyclotron system sales		—		1,600
Total	$	1,071	$	2,590

The Company’s performance obligations are typically part of contracts that have an original expected duration of one year or less. As such, the Company does not disclose the aggregate amount of the transaction price allocated to performance obligations that are unsatisfied (or partially satisfied) as of the end of the reporting period. The Company did not record any revenue related to performance obligations satisfied (or partially satisfied) during the three months ended March 31, 2026 and 2025.

Other income (expense), net

Other income (expense) , net consists of changes in the fair value of the Company's financial instruments measured at fair value, including the SAFE liability, preferred stock warrant liability, and derivative liabilities, losses recognized upon the issuance of equity-classified instruments where the aggregate fair value of instruments issued exceeds the proceeds received, and other non-operating gains and losses incidental to the Company's primary business activities. Changes in fair value of these instruments are recognized immediately in earnings as a component of other income (expense) , net in the condensed consolidated statements of operations.

3. Fair Value Measurement

Certain assets and liabilities are carried at fair value. Fair value is defined as the price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date.

Valuation techniques used to measure fair value require the Company to maximize the use of observable inputs and minimize the use of unobservable inputs. The fair value hierarchy distinguishes between market participant assumptions based on market data from independent sources (observable inputs) and an entity’s own assumptions based on the best information available (unobservable inputs). The fair value hierarchy consists of three broad levels, which gives the highest priority to observable inputs (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of the hierarchy are described below:

Level 1 – Valuations based on quoted prices in active markets for identical assets or liabilities.

Level 2 – Valuations based on inputs other than quoted prices included within Level 1 that are observable for the asset or liability, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data

Notes to Condensed Consolidated Financial Statements

(Amounts in thousands, except share and per share data)

Level 3 – Valuations based on inputs that are supported by little or no market activity that are significant to determining the fair value of assets or liabilities, including pricing models, discounted cash flow methodologies, and similar techniques.

The Company’s financial liabilities measured at fair value on a recurring basis consist of SAFE liability, preferred stock warrant liabilities, and derivative liabilities. Cash, accounts receivable, accounts payable, and accrued expenses and other current liabilities are carried at amounts that approximate fair value due to the short-term nature of these instruments.

The following table sets forth, by level, within the fair value hierarchy, the financial liabilities carried at fair value on a recurring basis:

	Fair value measurements as of
	March 31, 2026
	Level 1		Level 2		Level 3		Total
Warrant liability	$	—	$	—	$	99	$	99
Derivative liability		—		—		132		132
Total	$	—	$	—	$	231	$	231

	Fair value measurements as of
	December 31, 2025
	Level 1		Level 2		Level 3		Total
SAFE liability	$	—	$	—	$	4,086	$	4,086
Warrant liability		—		—		171		171
Derivative liability		—		—		111		111
Total	$	—	$	—	$	4,368	$	4,368

All recurring fair value measurements are classified within Level 3 due to the use of significant unobservable inputs. During the three months ended March 31, 2026 and 2025, there were no transfers or reclassifications between fair value measurement levels of assets or liabilities.

SAFE Liability

As discussed in Note 7, the Company determined that its SAFEs are freestanding financial instruments and classified them as liabilities. The Company measures the SAFEs at fair value based on significant inputs not observable in the market, which causes it to be classified as a Level 3 measurement within the fair value hierarchy. On March 31, 2026, all remaining outstanding SAFEs converted into 4,433,411 shares of Series F redeemable convertible preferred stock. Accordingly, no SAFE liability remained outstanding as of March 31, 2026. See Note 7 for additional information.

Preferred Stock Warrant Liability

5. Short-term Debt

2023 Term Loan and Warrants

In February 2023, the Company entered into a term loan agreement with a principal amount of $5.5 million (the “2023 Term Loan”), bearing interest at 17% per annum with an existing investor of the Company who is a related party. See Note 16 for additional information regarding related party transactions. The 2023 Term Loan matures in May 2026, as amended. Interest is payable at maturity.

In connection with the issuance of the 2023 Term Loan, the Company issued 220,000 warrants to purchase shares of Series F redeemable convertible preferred stock at an exercise price of $1.40 per share (the “Preferred Stock Warrants”). The Preferred Stock Warrants expire in February 2033. The Preferred Stock Warrants are classified as a liability and are remeasured at fair value at each reporting date, with changes in fair value recognized in other income (expense), net in the condensed consolidated statements of operations (see Note 3 Fair Value Measurement). In August 2025, the investor exercised 110,000 of the Preferred Stock Warrants. As of March 31, 2026 and December 31, 2025, there were 110,000 Preferred Stock Warrants outstanding, respectively.

In connection with subsequent amendments, the Company issued an aggregate of 1,250,000 common stock warrants, which are equity classified and were recorded as a debt discount amortized to interest expense over the remaining term of loan at the time of each amendment.

The outstanding principal balance was $5.5 million at March 31, 2026 and December 31, 2025, respectively. Accrued interest was $427 and $164 as of March 31, 2026 and December 31, 2025, respectively. The unamortized debt discount was $66 and $187 as of March 31, 2026 and December 31, 2025, respectively. Total interest expense, including amortization of the debt discount, was $548 and $287 for the three months ended March 31, 2026 and 2025, respectively.

Promissory Notes

In April 2025, the Company issued an unsecured promissory note to a board member in the principal amount of $440. The note bears interest at 11% per annum and matures on April 9, 2026. Interest is payable at maturity, and all unpaid principal and accrued interest are due on the maturity date.

In March 2026, the Company entered into note purchase agreements with the same board member and issued (i) an unsecured promissory note in the principal amount of $330, arising from the conversion of a related party advance, bearing interest at 11% per annum and maturing on March 1, 2027, (ii) an unsecured promissory note in the principal amount of $200, bearing interest at 11% per annum and maturing on March 12, 2027, and (iii) an unsecured promissory note in the principal amount of $375, bearing interest at 15% per annum and maturing on April 24, 2026. This promissory note included warrants to purchase 300,000 shares of the Company's common stock with an exercise price of $0.01 per share. The common stock warrants are equity classified. The fair value of the warrants at issuance was recorded as a debt discount against the related promissory note and is amortized to interest expense over the term of the note. The warrants had an aggregate fair value of $430.

In March 2026, the Company also issued an unsecured promissory note in the principal amount of $150 to an existing investor, bearing interest at 15% per annum and maturing on April 30, 2026, with warrants to purchase 120,000 shares of the Company's common stock at an exercise price of $0.01 per share. The common stock warrants issued in connection with the promissory notes are equity classified and were recorded as a debt discount amortized to interest expense over the respective terms of the notes. The warrants had an aggregate fair value of $175.

(Amounts in thousands, except share and per share data)

As of March 31, 2026 and December 31, 2025, the outstanding principal balance of the promissory notes was $1.5 million and $0.4 million, respectively. Accrued interest totaled $54 and $40 as of March 31, 2026 and December 31, 2025, respectively, and was included in accrued expenses and other current liabilities on the condensed consolidated balance sheets. Total interest expense related to the promissory notes, including amortization of the debt discount, was $139 and $0 for the three months ended March 31, 2026 and 2025, respectively.

Financing Agreements

In March 2026, the Company entered into two financing agreements with an unrelated third party with aggregate principal amounts of $62 and $44. The agreements bear interest at 8.2% and 8.3% per annum, respectively, and mature on November 1, 2026. As of March 31, 2026 the outstanding principal balance of the financing agreements was $106 and was classified as short-term debt on the condensed consolidated balance sheets. Interest expense was not material for the three months ended March 31, 2026.

Repayment of short-term debt

All outstanding short-term debt agreements, including accrued interest, were repaid in connection with the closing of the Merger in April 2026. Refer to Note 17, Subsequent Events, for additional information.

6. Convertible Notes

2023 Notes and 2024 Note

During 2023 and 2024, the Company issued unsecured convertible promissory notes with aggregate principal amounts of $10.0 million each (the “2023 Notes” and “2024 Note,” respectively). The 2024 Note included an embedded conversion feature that was bifurcated and accounted for as a derivative liability, remeasured to fair value at each reporting date, with changes in fair value recognized in other income (expense), net in the condensed consolidated statements of operations.

On October 31, 2025, the Company and the holders entered into a conversion agreement pursuant to which all outstanding principal and accrued interest were converted into shares of Series F redeemable convertible preferred stock at $1.40 per share. The Company accounted for the transaction as a debt extinguishment. Upon conversion, the embedded conversion feature derivative was remeasured to fair value immediately prior to conversion and extinguished. As a result, there were no outstanding balances related to the 2023 Notes, the 2024 Note, or the related embedded derivative as of March 31, 2026 or December 31, 2025.

No interest expense was recognized on the 2023 Notes or 2024 Note during the three months ended March 31, 2026. Interest expense related to the 2023 Notes and 2024 Note was $207 and $197, respectively, for the three months ended March 31, 2025. No change in fair value of the embedded conversion feature was recognized during the three months ended March 31, 2026 as the derivative was extinguished on October 31, 2025. The Company recognized a change in fair value of $3 on the embedded conversion feature during the three months ended March 31, 2025.

Make-Whole Provision

The Conversion Agreement includes a one-time make-whole provision that may require the Company to issue additional shares of Series F redeemable convertible preferred stock if the price per share in the Company’s next equity financing is below a stated threshold. The Company determined that the make-whole provision represents a derivative liability. The derivative liability was initially recorded at its estimated fair value on October 31, 2025 of $1.0 million and is remeasured at fair value at each reporting date, with changes in fair value recognized in other income (expense), net in the condensed consolidated statements of operations. The fair value of the make-whole derivative liability was $48 and $40 as of March 31, 2026 and December 31, 2025, respectively. The Company recognized a change in fair value of $8 during the three months ended March 31, 2026. No change in fair value was recognized during the three months ended March 31, 2025 as the make-whole provision did not exist prior to October 31, 2025. As further discussed in Note 17, Subsequent Events, in connection with the closing of the Merger, the make-whole derivative liability was derecognized in its entirety in April 2026.

7. SAFE Liability

Since inception, the Company has issued Simple Agreements for Future Equity (“SAFEs”) to multiple investors for aggregate principal proceeds of $45.7 million. The SAFE holders are entitled to receive shares of the Company’s redeemable convertible preferred stock upon the occurrence of a qualifying equity financing event. In the event of a liquidity or dissolution event, the SAFEs provide for settlement in accordance with their contractual terms. The SAFEs grant holders the right to receive shares of the Company’s redeemable convertible preferred stock upon the occurrence of a qualifying equity financing event at a 15% discount to the price per share paid by other investors in such financing.

The Company determined that the SAFEs are freestanding financial instruments and are classified as liabilities, as the SAFEs represent an obligation to issue a variable number of shares for a fixed monetary amount. The SAFEs are initially recorded at fair value upon issuance and subsequently remeasured to fair value at each reporting date, with changes in fair value recognized in the condensed consolidated statements of operations. Issuance costs related to the SAFEs are expensed as incurred.

During the three months ended March 31, 2026 and 2025, the Company issued SAFEs with aggregate proceeds of $2.4 million and $0.1 million, respectively. All SAFEs issued during the three months ended March 31, 2026 included common stock warrant coverage. The warrants are equity classified. The SAFE liability and the warrants were recorded at their respective fair values on the issuance date, with $2.4 million and $2.2 million allocated to the SAFE liability and the warrants, respectively. Any excess of the aggregate fair value of the instruments issued over the proceeds received was recognized as an upfront loss of $2.2 million and included in other income (expense), net in the condensed consolidated statements of operations during the three months ended March 31, 2026. No SAFEs with common stock warrant coverage were issued during the three months ended March 31, 2025. The Company recognized a loss on change in fair value of the SAFE liability of $134 and a gain of $2.1 million during the three months ended March 31, 2026 and 2025, respectively.

Election to Convert SAFEs

On October 31, 2025, holders of SAFEs with an aggregate carrying value of $50.7 million elected to settle their SAFEs into shares of the Company’s Series F redeemable convertible preferred stock at a conversion price of $1.40 per share. The Company accounted for the transaction as an extinguishment of the SAFE liability and, in connection with the conversion, recognized a freestanding make-whole derivative liability as described below.

On March 31, 2026, holders of all remaining outstanding SAFEs converted into shares of the Company's Series F redeemable convertible preferred stock at $1.40 per share. The SAFE liability was remeasured to fair value immediately prior to conversion, and the Series F redeemable convertible preferred stock was recorded at an amount equal to that fair value. No additional gain or loss was recognized upon conversion. As a result, no SAFE liability remained outstanding as of March 31, 2026.

Make-Whole Provision

In connection with the October 31, 2025 SAFE conversion, the Company granted a one-time make-whole right to the converted investors. No make-whole provision was granted in connection with the March 31, 2026 SAFE conversion. The Company determined that the make-whole provision represents a freestanding derivative liability. The derivative liability was initially recorded at its estimated fair value of $1.9 million on October 31, 2025 and is subsequently remeasured at fair value at each reporting date, with changes in fair value recognized in the condensed consolidated statements of operations. The fair value of the derivative liability related to the make-whole provision was $84 and $71 as of March 31, 2026 and December 31, 2025. The Company recognized a change in fair value of $13 for the three months ended March 31, 2026. As further discussed in Note 17, Subsequent Events, in connection with the closing of the Merger, the make-whole derivative liability was derecognized in its entirety in April 2026.

Contingent Equity Arrangement Associated with a SAFE

In connection with a SAFE issued in 2023, the Company entered into an arrangement that provided the investor with the right to receive a warrant upon the occurrence of certain future events. The Company previously concluded that no present obligation existed under this arrangement prior to the resolution of the applicable contingencies and, accordingly, no amount had been recognized in the Company’s historical financial statements. As further discussed in Note 17, Subsequent Events, the Company settled this arrangement in April 2026.

8. Operating Leases

The Company leases various facilities under operating leases. Leased facilities include manufacturing facilities, radiopharmaceutical production facilities, and office spaces. The Company combines lease and non-lease components, therefore there is no allocation of lease payments to non-lease components. Short-term leases with an initial term of 12 months or less are recognized on a straight-line basis over the lease term.

The components of total lease costs for operating leases during the three months ended March 31, 2026 and 2025 were as follows:

	Three Months Ended March 31,
	2026		2025
Operating lease cost	$	144	$	137
Variable lease cost		36		23

The supplemental cash flow information related to operating leases during the three months ended March 31, 2026 and 2025 were as follows:

9. Commitments and Contingencies

Litigation and Claims

From time to time, the Company may be involved in legal proceedings in the normal course of business. The Company assesses the need to record a liability for litigation and contingencies. Reserve estimates are recorded when and if it is determined that a loss-related matter is both probable and reasonably estimable.

Litigation Settlement and Revenue Impact 

The Company was party to litigation associated with a prior commercial arrangement. In January 2026, the Company resolved the matter by entering into a supply agreement with the customer. Under the terms of the agreement, the customer may purchase specified radioisotopes at a per-unit contractual discount until aggregate discounts total $2.8 million (the “Settlement Credit”). The credit is nonrefundable and does not require the customer to make minimum purchase commitments.

The Company concluded that the Settlement Credit represents consideration payable to a customer within the scope of ASC 606, Revenue from Contracts with Customers. Accordingly, the Settlement Credit will be recognized as a reduction of transaction price and recorded as a reduction of revenue as the customer exercises its right to purchase product at the discounted price. Revenue will continue to be recognized upon transfer of control of the product to the customer.

Purchase Commitments

As of March 31, 2026, the Company did not have any significant noncancelable purchase commitments.

				157,039,424		145,182,811	$	191,199	$	167,038

During the three months ended March 31, 2026, all remaining outstanding SAFEs converted into 4,433,411 shares of Series F redeemable convertible preferred stock at a conversion price of $1.40 per share. Because the redemption events are not solely within the control of the Company, the redeemable convertible preferred stock continues to be presented outside of permanent equity as mezzanine equity on the condensed consolidated balance sheets.

11. Stockholders’ Deficit

Common Stock

Each share of common stock is entitled to one vote. The holders of common stock are also entitled to receive dividends whenever funds are legally available and when declared by the Board of Directors, subject to the prior right of holders of all series of stock outstanding. Through March 31, 2026, no dividends have been declared or paid.

Under the 2016 Plan, ISOs can only be granted to employees and NSOs can be granted to employees, directors, and key advisors. The Board of Directors determines the terms and conditions of the awards, including the number of awards to be granted and vesting criteria at the time of grant. The term of each option shall be stated in the option agreement; however, the term shall be no more than ten years from the date of the grant thereof. Stock options must be granted with an exercise price no less than the stock’s fair market value at the date of grant.

13. Common Stock Warrants

The following table summarizes common stock warrant activity for the three months ended March 31, 2026:

	Number of warrants			Weighted Average Exercise Price
Outstanding at December 31, 2025		10,176,273		$	1.08
Issued		2,168,829			0.01
Exercised		(2,639,038	)		0.01
Outstanding at March 31, 2026		9,706,064		$	1.13

During the three months ended March 31, 2026, the Company issued an aggregate 2,168,829 common stock warrants, consisting of 1,748,829 common stock warrants issued in connection with SAFEs, as described in Note 7 SAFE Liability, and 420,000 common stock warrants issued in connection with promissory notes, as described in Note 5 Short-Term Debt. These warrants have an exercise price of $0.01 per share and a contractual term of ten years.

The fair value of common stock warrants issued was estimated using the following assumptions:

	Three months ended March 31, 2026
Expected term (in years)	10
Expected volatility	56.6% - 57.9%
Risk-free rate	4.0% - 4.3%
Dividend yield	0%

14. Income Taxes

For the three months ended March 31, 2026 and 2025, the Company recorded no income tax expense or benefit. The Company incurred pre-tax losses for the three months ended March 31, 2026 and 2025 and continues to maintain a full valuation allowance against its deferred tax assets due to its cumulative loss position and projected future losses. Accordingly, the Company’s effective tax rate was 0.0% for each of the three months ended March 31, 2026 and 2025. The Company’s effective tax rate differs from the U.S. federal statutory rate of 21.0% primarily due to the valuation allowance recorded against the Company’s net deferred tax assets.

15. Net Loss Attributable to Common Stockholders

Basic net loss per share attributable to the Company’s common stockholders is computed by dividing the net loss attributable to the Company’s common stockholders by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is the same as basic net loss per share for all years presented because the effects of potentially dilutive items were anti-dilutive given the Company’s net loss position in each period presented.

17. Subsequent Events

The Company has evaluated subsequent events through May 20, 2026, the date the condensed consolidated financial statements were issued.

Reverse Merger and Related Transactions

As discussed in Note 1, Description of Business, On April 9, 2026, the Company completed its merger with JDEV Acquisition Corp. ("JDEV") pursuant to the Agreement and Plan of Merger. The Company survived as a wholly owned subsidiary of JDEV, which was subsequently renamed Ionetix Corporation (the “combined company”). The merger was treated as a reverse recapitalization, with the Company determined to be the accounting acquirer. At the effective time of the merger, each outstanding share of the Company's common stock and preferred stock was converted into shares of the combined company’s common stock at a conversion ratio of 0.5014. All outstanding options and warrants of the Company were assumed by JDEV and converted into options and warrants to purchase shares of the combined company’s common stock, with the number of underlying shares and exercise prices adjusted based on the conversion ratio.

Contemporaneously with the closing of the merger, the combined company sold 10,777,268 shares of common stock in a private placement at a purchase price of $3.00 per share, generating aggregate gross proceeds of $32.3 million. The combined company also issued warrants to purchase an aggregate of 862,183 shares of combined company common stock at an exercise price of $3.00 per share to the placement agent of the transaction with an aggregate grant date fair value of approximately $1.5 million.

In connection with the closing of the merger, the make-whole derivative liability was remeasured to fair value immediately prior to closing, with the related fair value adjustment being not material. Upon closing, the make-whole derivative liability was derecognized in its entirety, resulting in a gain or loss that was not material.

In connection with the closing of the merger, all outstanding short-term debt was also repaid. See Note 5 — Short-Term Debt for additional information.

Settlement of Contingent Equity Arrangement

As further described in Note 7, SAFE Liability, the Company was party to a contingent equity arrangement associated with a SAFE issued in 2023. On April 9, 2026, the Company settled the arrangement in full by terminating all prior warrants and contingent rights and issuing a new ten-year warrant to purchase 6,443,076 shares of the Company's common stock at an exercise price of $0.01 per share. The new warrant is classified within stockholders' equity. The Company determined the fair value of the new warrant at issuance to be approximately $10.0 million, which was recognized as expense with a corresponding increase to additional paid-in capital. Upon the closing of the Merger, the new warrant was exchanged for a warrant to purchase shares of the combined company’s common stock pursuant to the terms of the Merger Agreement.

Termination agreement with an Investor

In April 2026, the Company entered into a termination agreement with an investor pursuant to which the make-whole right and certain other investor rights and related agreements were terminated in their entirety. In connection with the termination, the combined company issued 277,696 shares of common stock to the investor as consideration.

The make-whole derivative liability was remeasured to fair value immediately prior to the termination date, and the related fair value adjustment was immaterial. Upon execution of the termination agreement, the make-whole derivative liability was derecognized, and the 277,696 shares issued were measured at fair value of $833 as of the termination date, based on the $3.00 per share price of the contemporaneous private placement of the combined company’s common stock. The difference between the carrying amount of the make-whole derivative liability and the fair value of the shares issued was recognized in the condensed consolidated statements of operations.

Some of the information contained in this discussion and analysis or set forth elsewhere in this Current Report, including information with respect to our plans and strategy for our business, includes forward-looking statements involving risks and uncertainties as described under the heading “Forward-Looking Statements” elsewhere in this Current Report. You should review the section titled “Risk Factors” in our Current Report on Form 8-K filed with the SEC on April 16, 2026, as supplemented by this Current Report, for a discussion of important factors that could cause actual results to differ materially from the results described in or implied by the forward-looking statements and could otherwise affect our intended plans of operations.

Overview

Background

Incorporated in the State of Delaware in 2009, Ionetix Corporation (following the Merger described below, “Ionetix” or the “Company”) was founded to develop superconducting cyclotron technology to produce isotopes for medical and industrial purposes. Our founding premise was to use this novel cyclotron technology to produce isotopes in a smaller and thus more cost-effective footprint. Our mission is to produce otherwise hard-to-obtain isotopes, using a combination of our proprietary cyclotron technology and equipment sourced from third parties.

Our leadership team has a combined 50+ years of direct experience with nuclear medicines, cyclotron technology solutions and engineering, government and community engagement. Our board members include pre-eminent experts in pharmaceutical and biotechnology research and development and manufacturing. We believe that the depth of our expertise and our cyclotron technology solutions uniquely position us to become the market leader in the manufacturing of isotopes for medical and industrial purposes.

The Reverse Merger

On April 9, 2026, JDEV Acquisition Corp. (“JDEV” and after the Merger, Ionetix), JDEV Merger Subsidiary (“Merger Sub”) and pre-Merger Ionetix Corporation (“Legacy Ionetix”) completed the merger contemplated by the Agreement and Plan of Merger and Reorganization dated April 9, 2026, pursuant to which Merger Sub merged with and into Legacy Ionetix, with Legacy Ionetix continuing as the surviving corporation and becoming a wholly owned subsidiary of the Company (the “Merger”). In connection with the Merger, JDEV changed its name to Ionetix Corporation, and the combined company will continue the existing business operations of Ionetix as a public reporting company.

At the effective time of the Merger, each outstanding share of Legacy Ionetix common stock and preferred stock was converted into shares of common stock of the combined company based on the Conversion Ratio. All outstanding stock options and warrants of Legacy Ionetix were assumed and converted into options and warrants to purchase shares of common stock of the combined company, with the number of underlying shares and exercise prices adjusted based on the Conversion Ratio.

For financial reporting purposes, the Merger was accounted for as a reverse recapitalization, with Ionetix determined to be the accounting acquirer. Accordingly, the historical financial results of Legacy Ionetix prior to the Merger are treated as the historical financial results of the combined company, and the results of operations discussed below for the three months ended March 31, 2026 and 2025 represent the historical results of Legacy Ionetix prior to the Merger.

Contemporaneously with the closing of the Merger, we sold 10,777,268 shares of common stock in a private placement at a purchase price of $3.00 per share, generating aggregate gross proceeds of $32.3 million and net proceeds of $29.7 million after deducting placement agent fees and expenses. The net proceeds are expected to be used for general working capital and corporate purposes, including research and development, engineering and scale-up manufacturing of our medical isotopes, as well as fees and expenses related to the Merger and the private placement financing.

For additional information regarding the Merger and related transactions, see our Current Report on Form 8-K filed with the SEC on April 16, 2026.

Components of Results of Operations

Revenue

Our revenues are generated primarily from (i) diagnostic drug and medical radioisotopes sales, (ii) cyclotron system sales, and (iii) consulting services and system support services.

Diagnostic drug and medical radioisotopes sales represent our principal source of revenue. Under these arrangements, customers place purchase orders pursuant to master sales agreements, with each delivered dose representing a distinct performance obligation. Revenue is recognized upon delivery, when control of the product transfers to the customer. Because these products are ordered based on clinical requirements and administered as part of patient care, demand is closely tied to real-time utilization. We have only begun sales of therapeutic radioisotopes in late 2025, and we expect revenues from the sale of diagnostic drugs to continue to represent the primary driver of our business, with future growth influenced by the development and commercialization of additional isotopes, including therapeutic isotopes, as well as continuing utilization of PET imaging products.

Cyclotron system revenues are generated from the delivery of equipment together with installation and related activities necessary to verify functionality in accordance with contractual specifications. These activities are combined into a single performance obligation, and revenue is recognized upon completion of installation and formal customer acceptance. Cyclotron system sales are generally driven by customer-specific deployment needs and the timing of system installations. As a result, we expect revenues from cyclotron sales to fluctuate from period to period.

Consulting services and system support services are typically recognized over time as services are performed because the customer simultaneously receives and consumes the benefits of our performance. We measure progress using a cost-to-cost input method, recognizing revenue based on costs incurred relative to total estimated costs, with estimates updated as facts and circumstances change.

Operating Expenses

Cost of Revenue

Cost of revenue consists primarily of costs associated with the manufacture and delivery of our products and related services, including materials and components, personnel-related costs, production-related overhead and shipping and handling costs. Production-related overhead includes facility costs, utilities, depreciation of production equipment, and hosting and cloud infrastructure costs. Cost of revenue also includes manufacturing-related adjustments such as production variances, warranty costs, scrap, and write-downs of excess or obsolete components. As production volume and system deliveries increase, cost of revenue is expected to increase in absolute dollars.

Selling, General and Administrative

Selling, general and administrative expenses consist primarily of personnel-related costs, including salaries, health insurance, payroll taxes, and stock-based compensation. Selling, general and administrative expenses also include consulting and professional service fees and other general corporate and administrative expenses.

2

As we continue to grow our business and expand our commercial presence, we expect selling, general and administrative expenses to increase in absolute dollars. In addition, we expect selling, general and administrative expenses to increase in the near term as a result of operating as a public company, including costs associated with compliance with SEC reporting requirements, audit and legal fees, insurance, and other corporate governance and administrative expenses.

Research and Development

Research and development expenses consist of costs incurred in connection with our development activities and are expensed as incurred. These expenses primarily include personnel-related costs, such as salaries, health insurance, and other employee benefits. Research and development expenses also include depreciation and amortization of development equipment and related assets, legal and regulatory costs, and other expenses necessary to support our development activities.

We have invested, and intend to continue to invest, in research and development activities to support the expansion of our diagnostic isotope offerings and the advancement of therapeutic isotope programs, including alpha-emitting radionuclides. Research and development expenses may fluctuate from period to period based on the timing and scope of development initiatives, regulatory activities, and clinical supply programs. We expect research and development expenses to increase in absolute dollars as we continue to invest in technology, production capabilities, and isotope development.

Interest Expense, Net

Interest expense, net consists primarily of interest incurred on outstanding debt obligations, partially offset by interest income earned on our cash and cash equivalents.

Other Income (Expense), Net

Other Income (expense), net consists primarily of non-cash charges related to the fair value remeasurement of financial instruments and gains or losses associated with financing transactions, as well as other non-operating items.

Provision for Income Taxes

We have incurred net losses since inception and maintain a full valuation allowance against our deferred tax assets. As a result, income tax expense was not material for the periods presented.

Revenue

	Three Months Ended March 31,
	2026		2025		Change %
		(In thousands)
Revenue	$	1,071	$	2,590		-59	%

Total revenue was $1.1 million for the three months ended March 31, 2026 compared to $2.6 million for the three months ended March 31, 2025, a decrease of $1.5 million, or 59%. The decrease was primarily driven by a $1.6 million decrease in cyclotron system sales, as no cyclotron system sales were recognized during the current period, compared to $1.6 million recognized in the prior-year period in connection with the fulfilment of a cyclotron contract. This decrease reflected the timing of customer-specific system deployments and installations. Diagnostic drug and medical radioisotopes sales were $1.1 million for the three months ended March 31, 2026 compared to $1.0 million for the three months ended March 31, 2025.

Cost of revenue	$	1,497	$	2,090		-28	%

Cost of revenue was $1.5 million for the three months ended March 31, 2026 compared to $2.1 million for the three months ended March 31, 2025, a decrease of $0.6 million, or 28%. The change was primarily driven by the decrease in system sales costs, reflecting that no cyclotron system sales were recognized in the current period.

Selling, General and Administrative

	Three Months Ended March 31,
	2026		2025		Change %
		(In thousands)
Selling, general and administrative	$	2,904	$	2,882		1	%

Selling, general and administrative expenses remained relatively flat at $2.9 million for the three months ended March 31, 2026 compared to the same period in 2025.

Research and Development

	Three Months Ended March 31,
	2026		2025		Change %
		(In thousands)
Research and development	$	702	$	1,347		-48	%

Research and development expenses were $0.7 million for the three months ended March 31, 2026 compared to $1.3 million for the three months ended March 31, 2025, a decrease of $0.6 million, or 48%. The decrease was primarily driven by a $0.4 million decrease in personnel-related costs, reflecting the transition of certain employees and related costs from research and development activities associated with alpha-emitting isotopes to cost of revenue in December 2025, as the related facility progressed toward operational readiness.

Interest Expense, Net

	Three Months Ended March 31,
	2026		2025		Change %
		(In thousands)
Interest expense, net	$	374	$	780		-52	%

Interest expense, net was $0.4 million for the three months ended March 31, 2026 compared to $0.8 million for the three months ended March 31, 2025, a decrease of $0.4 million, or 52%. The decrease was primarily driven by the conversion of the convertible notes in the fourth quarter of 2025, which eliminated the related interest expense in the three months ended March 31, 2026.

Other Income (Expense), Net

	Three Months Ended March 31,
	2026			2025		Change %
		(In thousands)
Other income (expense), Net	$	(2,535	)	$	2,118		-220	%

Other expense, net was $2.5 million for the three months ended March 31, 2026 compared to other income, net, of $2.1 million for the three months ended March 31, 2025, representing change of $4.7 million. The change was primarily driven by a $2.2 million upfront loss recognized in connection with the issuance of SAFEs with common stock warrant coverage during the three months ended March 31, 2026, reflecting the excess of the aggregate fair value of the instruments issued over the proceeds received. Additionally, the fair value of SAFE liabilities swung from a $2.1 million gain during the three months ended March 31, 2025 to a $0.1 million loss during the three months ended March 31, 2026, reflecting changes in the estimated fair value of outstanding SAFEs prior to their conversion into Series F redeemable convertible preferred stock on March 31, 2026.

5

Liquidity and Capital Resources

Since inception, we have financed our operations primarily through the issuance of redeemable convertible preferred stock, SAFEs, convertible notes, short-term debt and, most recently, the proceeds from the private placement financing completed in connection with the Merger. Our primary requirements for liquidity and capital are to fund working capital, capital expenditures, research and development, manufacturing, sales and marketing efforts, site deployment activities, commercial expansion and general corporate purposes.

We have incurred significant operating losses and negative cash flows since inception. For the three months ended March 31, 2026, we incurred a net loss of $6.9 million. As of March 31, 2026, we had an accumulated deficit of $193.5 million and cash and restricted cash of approximately $0.3 million. On April 9, 2026, we completed the Merger, in connection with which the combined company raised $29.7 million after deducting placement agent fees and expenses from a private placement financing.

We have incurred operating losses to date and expect to continue to incur losses for the foreseeable future as we invest in the growth of our business. Based on our current operating plan, we believe that our existing cash, together with the net proceeds from the private placement, will not be sufficient to fund our operations for at least the next twelve months.

Our future capital requirements will depend on many factors, including the timing and extent of our research and development activities, the scale-up of manufacturing operations, the pace of commercial expansion, and the timing of site deployments. We may seek to raise additional capital through equity or debt financings, strategic collaborations, or other arrangements to support our long-term growth objectives. There can be no assurance that such financing will be available on favorable terms, or at all.

Cash Flows

The following table summarizes our cash flows for the periods presented:

	Three Months Ended March 31,
	2026			2025
	(In thousands)
Net cash used in operating activities	$	(2,213	)	$	(4,385	)
Net cash used in investing activities	$	(1,483	)	$	(838	)
Net cash provided by financing activities	$	3,546		$	114

Operating Activities

Net cash used in operating activities for the three months ended March 31, 2026 was $2.2 million, which resulted from a net loss of $6.9 million, adjusted for non-cash charges of $4.1 million and net cash inflows from changes in operating assets and liabilities of $0.6 million. Non-cash charges of $4.1 million primarily consisted of upfront loss of $2.2 million recognized in connection with the issuance of SAFEs with common stock warrant coverage during the three months ended March 31, 2026, reflecting the excess of the aggregate fair value of the instruments issued over the proceeds received, depreciation and amortization of $0.9 million, amortization of debt discount and issuance costs of $0.2 million, and stock-based compensation of $0.1 million. Cash inflows from changes in operating assets and liabilities was $0.6 million, primarily due to increases of $0.7 million in accounts payable reflecting the timing of payments.

Net cash used in operating activities for the three months ended March 31, 2025 was $4.4 million, which resulted from a net loss of $2.4 million, adjusted for net non-cash adjustments of $1.0 million and net cash outflows from changes in operating assets and liabilities of $1.0 million. Net non-cash adjustments primarily reflected a $2.1 million gain on the change in fair value of SAFE liabilities, partially offset by depreciation and amortization expense of $0.8 million, stock-based compensation of $0.2 million, and amortization of debt discount and issuance costs of $0.1 million. Net cash outflows from changes in operating assets and liabilities of $1.0 million were primarily due to a $1.3 million decrease in accrued expenses and other liabilities, primarily reflecting a decrease in customer deposits as services were performed, and a $0.4 million increase in accounts receivable, reflecting revenue recognized from diagnostic drug and medical radioisotopes sales in the period, partially offset by a $0.7 million decrease in inventory consumed in production.

6

Investing Activities

Net cash used in investing activities for the three months ended March 31, 2026 and 2025 was $1.5 million and $0.8 million, respectively, and consisted primarily of purchases of property and equipment to support ongoing operational and capacity expansion.

Financing Activities

Net cash provided by financing activities was $3.5 million for the three months ended March 31, 2026, primarily consisting of $2.4 million of SAFE issuances, $0.8 million of net proceeds from short-term debt, and $0.4 million proceeds from related party advances.

Net cash provided by financing activities was $0.1 million for the three months ended March 31, 2025, primarily consisting of $0.1 million of SAFE issuances.

Contractual Obligations and Commitments

As of March 31, 2026, our material contractual obligations consisted primarily of debt arrangements and operating lease commitments.

As of March 31, 2026, we had $6.5 million of short-term debt obligations outstanding. The short-term debt matures between April 2026 and March 2027. Subsequent to March 31, 2026, all outstanding short-term debt obligations, including accrued interest, were repaid in full in connection with the closing of the Merger.

We also have operating lease commitments for our facilities and equipment. These lease obligations extend beyond March 31, 2026 in accordance with the respective lease terms. As of March 31, 2026, we had aggregate future minimum operating lease commitments of approximately $1.5 million, of which approximately $0.5 million is payable within the next 12 months.

We do not have any off-balance sheet arrangements and have no material purchase commitments.

Critical Accounting Policies and Estimates

Our condensed consolidated financial statements are prepared in accordance with U.S. GAAP. The preparation of condensed consolidated financial statements also requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, costs and expenses, and related disclosures. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results could differ significantly from the estimates made by management. To the extent that there are differences between our estimates and actual results, our future financial statement presentation, financial condition, results of operations, and cash flows will be affected.

There have been no material changes to our critical accounting policies and estimates as compared to those described in the section titled “Critical Accounting Policies and Estimates” in Management’s Discussion and Analysis of Financial Condition and Results of Operations in our Current Report on Form 8-K filed with the SEC on April 16, 2026.

Exhibit 99.5

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

The following unaudited pro forma condensed combined financial information and accompanying notes present the combination of the financial information of JDEV Acquisition Corp. (“JDEV” or “Parent”) and Ionetix Corporation (“Ionetix”), adjusted to give effect to the Merger and related transactions (collectively, the “Transactions”).

The following unaudited pro forma condensed combined financial information has been prepared in accordance with Article 11 of Regulation S-X as amended by the final rule, Release No. 33-10786 “Amendments to Financial Disclosures about Acquired and Disposed Businesses.” For purposes of this section, Ionetix and JDEV are collectively referred to as the “Companies,” and the Companies, subsequent to the Merger, are referred to herein as the “Combined Company.”

The historical financial information of JDEV was derived from the unaudited financial statements as of and for the three months ended March 31, 2026 included in JDEV’s Quarterly Report on Form 10-Q filed with the SEC on May 20, 2026 (the “JDEV 10-Q”) and the audited financial statements of JDEV as of and for the period from November 26, 2025 (inception) to December 31, 2025 included in JDEV’s Form 10 filed with the SEC on February 4, 2026 (the “JDEV Form 10”). The historical financial information of Ionetix was derived from the unaudited financial statements of Ionetix as of and for the three months ended March 31, 2026, and the audited condensed financial statements of Ionetix as of and for the year ended December 31, 2025 included elsewhere in this Current Report on Form 8-K (this “Report”). This unaudited pro forma condensed combined financial information should be read together with (i) JDEV’s historical financial statements and related notes included in JDEV’s 10-Q and Form 10 and (ii) Ionetix’s historical financial statements and related notes, and the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and other financial information included elsewhere in this Report. Capitalized terms used but not defined herein shall have the meanings ascribed to them in the Report.

Contemporaneously with the Merger, JDEV conducted a private placement offering (the “Offering”) and sold 10,777,268 shares of its common stock at a purchase price of $3.00 per share for gross proceeds of $32.3 million. In connection with the Offering, JDEV also issued warrants to purchase an aggregate of 862,183 shares of PubCo common stock at an exercise price of $3.00 per share to the Placement Agent. The unaudited pro forma condensed combined financial information and accompanying notes are adjusted to give effect to the Offering.

Notwithstanding the legal form, the Merger is expected to be accounted for as a reverse recapitalization in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). Under this method of accounting, JDEV will be treated as the acquired company for accounting purposes, and Ionetix will be treated as the accounting acquirer. Accordingly, the Merger will be treated as the equivalent of Ionetix issuing shares for the net assets of JDEV, accompanied by a recapitalization. Consequently, the net assets of JDEV will be stated at historical cost, with no goodwill or other intangible assets recorded, and operations prior to the Merger will be those of Ionetix. Ionetix has been determined to be the accounting acquirer for purposes of the Merger based on an evaluation of the following facts and circumstances:

● The assets of Ionetix represent a significant majority of the assets of the Combined Company.

● Ionetix stockholders have a majority of the voting power of the Combined Company.

● The executive officers of the Combined Company immediately after the Closing are the same individuals as those of Ionetix immediately prior to the Closing.

● Ionetix’s operations comprise the ongoing operations of the Combined Company.

The table directly below presents shares outstanding after the Transactions, as depicted in the unaudited pro forma condensed combined financial information, after giving effect to the Conversion Ratio:

Note 1 — Basis of Pro Forma Presentation

The unaudited pro forma condensed combined financial information was prepared in accordance with Article 11 of Regulation S-X, as amended by the final rule, Release No. 33-10786 “Amendments to Financial Disclosures about Acquired and Disposed Businesses,” and presents the Combined Company’s pro forma financial condition and results of operations based upon the historical financial information of each of JDEV and Ionetix after giving effect to the Transactions set forth in the notes to the unaudited pro forma condensed combined financial information. The adjustments presented in the unaudited pro forma condensed combined financial information have been identified and presented to provide relevant information necessary for an understanding of the Combined Company upon consummation of the Transactions.

Notwithstanding the legal form, the Merger will be accounted for as a reverse recapitalization in accordance with U.S. GAAP, as outlined above.

In connection with the Offering, JDEV also issued 862,183 warrants to purchase shares of PubCo Common Stock to the Placement Agent at an exercise price of $3.00 per share (the “Placement Agent Warrants”). The Placement Agent Warrants are accounted for as equity-classified instruments in accordance with U.S. GAAP and are initially measured at fair value. As the Placement Agent Warrants were issued to the Placement Agent in connection with the Offering, a capital transaction, they are considered offering costs recorded through additional paid-in capital.

The unaudited pro forma condensed combined financial information presented does not reflect any cost savings, operating synergies, tax savings or revenue enhancements that the consolidated company may achieve as a result of the Merger. Ionetix and JDEV did not have any historical relationship prior to the Merger. Accordingly, no pro forma adjustments were required to eliminate activities between the Companies.

The unaudited pro forma condensed combined financial information has been prepared based on the Ionetix and JDEV historical financial statements, as adjusted to give effect to the Merger and Offering. The unaudited pro forma condensed combined statements of operations for the three months ended March 31, 2026 and for the year ended December 31, 2025 give effect, on a pro forma basis, to the Transactions as if they had been consummated as of January 1, 2025. The unaudited pro forma condensed combined balance sheet as of March 31, 2026 is derived from the historical balance sheets of each of Ionetix and JDEV, adjusted on a pro forma basis as if the Transactions had been consummated as of March 31, 2026.

The pro forma adjustments reflecting the consummation of the Transactions are based on certain currently available information and certain assumptions and methodologies that each of Ionetix and JDEV believes are reasonable under the circumstances. The pro forma adjustments, which are described in the following notes, may be revised as additional information becomes available and is evaluated. Therefore, it is likely that the actual adjustments will differ from the pro forma adjustments, and it is possible the differences may be material. Each of Ionetix and JDEV believes that its assumptions and methodologies provide a reasonable basis for presenting all the significant effects of the Transactions based on information available to management at this time and that the pro forma adjustments give appropriate effect to those assumptions and are properly applied in the unaudited pro forma condensed combined financial information. There were no significant differences in accounting policies between JDEV and Ionetix that required pro forma adjustments in order to conform the historical condensed combined financial information.

Note 2 — Adjustments to Unaudited Pro Forma Condensed Combined Financial Information 

The following unaudited pro forma condensed combined financial information has been prepared in accordance with Article 11 of Regulation S-X. The pro forma condensed combined financial information does not include an income tax adjustment based on the history of Ionetix’s losses and the expectation that the Combined Company would not be able to realize the tax benefits of such losses. The pro forma condensed combined provision for income taxes does not necessarily reflect the amounts that would have resulted had the Companies filed consolidated income tax returns during the periods presented.

6 

The pro forma notes and adjustments, based on preliminary estimates that could change materially as additional information is obtained, are as follows:

Pro Forma Transaction Accounting Adjustments to Unaudited Pro Forma Condensed Combined Balance Sheet

(A) To reflect the issuance and sale of 10,777,268 shares of Parent common stock, par value of $0.0001 per share, to Private Placement Investors, for aggregate proceeds of $32.3 million.

(B) To reflect the derecognition of Ionetix’s derivative liability upon settlement related to the make-whole provision associated with the Series F preferred stock issued by Ionetix in October 2025.

In April 2026, the Company entered into a termination agreement with one of the Series F October 2025 investors pursuant to which the make-whole right and certain other investor rights and related agreements were terminated in their entirety. In connection with the termination, the investor received 277,696 shares of PubCo common stock as consideration. 

The make-whole derivative liability related to this investor was remeasured to fair value immediately prior to the termination date, and the related fair value adjustment was immaterial. Upon execution of the termination agreement, the make-whole derivative liability was derecognized, and the 277,696 shares issued were measured at fair value of $0.8 million as of the termination date. The difference between the carrying amount of the make-whole derivative liability and the fair value of the shares issued was recognized in the condensed combined statements of operations. 

This pro forma adjustment also includes the derecognition of the make-whole liability related to all other Series F preferred stock issued in October 2025.

(C) To reflect settlement of $5.3 million of estimated transaction costs incurred in connection with the Transaction, of which $2.9 million is settled in cash at the Closing and $0.9 million was previously capitalized as other noncurrent assets as of March 31, 2026. These transaction costs are preliminary estimates subject to change. The final amounts of Ionetix’s and JDEV’s transaction costs and the resulting effect on the financial position and results of operations of the Combined Company may differ significantly. These transaction costs are in connection with the Closing and related transactions and are deemed to be direct and incremental costs of the Merger. The transaction costs are accounted for as equity issuance costs and the unaudited pro forma condensed balance sheet reflects these costs as a reduction in cash with a corresponding decrease to additional paid-in-capital.

The total estimated transaction costs settled in cash include banker fees of $2.6 million, audit and accounting professional service fees of $0.6 million, and legal fees and other transaction related expenses of $0.6 million. The total estimated transaction costs include the issuance of 862,183 warrants to purchase shares of PubCo Common Stock to the Placement Agent, recorded as offering costs through additional paid-in capital of $1.5 million.

(D) To reflect the conversion of Ionetix redeemable convertible preferred stock into shares of PubCo Common Stock pursuant to the Conversion Ratio concurrent with the Closing.

(E) To reflect the recapitalization of Ionetix through the conversion of Ionetix common stock into PubCo Common Stock pursuant to the Conversion Ratio concurrent with the Closing, including the Ionetix common stock issued subsequent to quarter-end included in Note (B) above.

(F) To reflect the exchange of Ionetix’s Preferred Stock Warrants into warrants to purchase shares of PubCo Common Stock, pursuant to terms of the Merger Agreement. The Preferred Stock Warrants were previously redeemable, resulting in Ionetix classifying such warrants as liabilities in its historical financial statements.

Ionetix’s outstanding common stock warrants were also exchanged into warrants to purchase shares of PubCo Common Stock, pursuant to terms of the Merger Agreement. The Ionetix common stock warrants were previously classified as equity in Ionetix’s historical financial statements, and as a result, no pro forma adjustment is needed for the exchange of these common stock warrants.

(G) In connection with a SAFE issued in 2023, Ionetix was party to a side letter and subsequent formalized agreements (entered into in 2024) that provided an investor with the right to receive a warrant upon the occurrence of certain future events, including specified corporate transactions. The arrangement had not been recognized in Ionetix's historical financial statements as of March 31, 2026, as no present obligation existed prior to the resolution of the applicable contingencies.

7 

Ionetix settled the arrangement in full by terminating all prior warrants and contingent rights and issuing a new warrant to purchase shares of Ionetix common stock. The Company evaluated the new warrant and determined it meets the criteria for equity classification under U.S. GAAP. The fair value of the new warrant is approximately $10.0 million, which is recognized as a pro forma adjustment immediately prior to the Closing, with a corresponding increase to accumulated deficit and additional paid-in capital. Upon the Closing, the new warrant was exchanged for a warrant to purchase shares of PubCo Common Stock pursuant to the terms of the Merger Agreement.

(H) To reflect the settlement of JDEV’s historical liabilities that will be settled at transaction close.

(I) To reflect the repayment of Ionetix’s historical debt, including (i) the $5.5 million outstanding balance under Ionetix’s 2023 Term Loan, (ii) the $1.6 million of other short-term debt outstanding, and (iii) related accrued interest of $0.8 million, in each case using proceeds from the Offering.

(J) To reflect the elimination of JDEV’s historical accumulated deficit to additional paid-in capital as part of the reverse recapitalization of the Merger.

Pro Forma Transaction Accounting Adjustments to Unaudited Pro Forma Condensed Combined Statements of Operations – Three Months Ended March 31, 2026

The pro forma adjustments included in the unaudited pro forma condensed combined statement of operations for the three months ended March 31, 2026 are as follows:

(aa) To reflect reversal of $0.1 million related to the change in fair value of Ionetix’s SAFE liabilities, assuming the SAFEs were converted at the beginning of the period presented.

(bb) To reflect reversal of less than $0.1 million related to the change in fair value of Ionetix’s Preferred Stock Warrant liability recognized during the three months ended March 31, 2026, assuming the Preferred Stock Warrants were converted at the beginning of the period presented.

(cc) To reflect reversal of less than $0.1 million related to the change in fair value of Ionetix’s derivative liabilities recognized during the three months ended March 31, 2026.

(dd) To reflect reversal of $0.7 million of interest expense, of which $0.6 million is related to the interest expense recognized on Ionetix’s 2023 Term Loan and $0.1 million is related to the interest expense recognized on Ionetix’s promissory notes. This pro forma adjustment assumes all outstanding debt was fully repaid at the beginning of the period presented.

(ee) To reflect reversal of $2.2 million related to the non-cash loss recognized in connection with the issuance of SAFEs and common stock warrants.

Pro Forma Transaction Accounting Adjustments to Unaudited Pro Forma Condensed Combined Statements of Operations – Year Ended December 31, 2025

The pro forma adjustments included in the unaudited pro forma condensed combined statement of operations for the year ended December 31, 2025 are as follows:

(aa) To reflect reversal of $0.3 million related to the change in fair value of Ionetix’s SAFE liabilities, assuming the SAFEs were converted at the beginning of the period presented.

8 

(bb) To reflect reversal of $0.1 million related to the change in fair value of Ionetix’s Preferred Stock Warrant liability recognized during the year ended December 31, 2025, assuming the Preferred Stock Warrants were converted at the beginning of the period presented.

(cc) To reflect reversal of $2.8 million related to the change in fair value of Ionetix’s derivative liabilities recognized during the year ended December 31, 2025.

(dd) To reflect reversal of $3.2 million of interest expense, of which $1.5 million is related to the interest expense recognized on Ionetix’s 2023 Term Loan and $1.7 million is related to the interest expense recognized on Ionetix’s 2023 Notes and 2024 Note, and $0.1 million is related to the interest expense recognized on Ionetix’s unsecured promissory note. This pro forma adjustment assumes all outstanding debt was fully repaid at the beginning of the period presented.

(ee) To reflect reversal of $3.1 million related to the non-cash loss recognized in connection with the issuance of SAFEs and common stock warrants.

(ff) To reflect the $10.0 million expense recognized in connection with the settlement of a contingent equity arrangement immediately prior to the Closing, through the issuance of a new warrant to purchase shares of Ionetix common stock, as described in Note (G) above.

(gg) To reflect the $0.8 million expense recognized in connection with the settlement of a portion of the Ionetix make-whole derivative liability upon execution of a termination agreement with an investor, through the issuance of PubCo common stock, as described in Note (B) above.

Note 3 — Net Loss per Share

Represents the pro forma basic and diluted net loss per share to holders of Parent common stock calculated using the weighted-average common shares outstanding as a result of the pro forma adjustments. The pro forma basic and diluted earnings per share amounts presented in the unaudited pro forma condensed combined statement of operations are based on the number of shares of Parent common stock expected to be outstanding as if the Transactions had occurred on January 1, 2025. The calculation of weighted-average shares outstanding for pro forma basic and diluted earnings per share assumes that the shares issuable in connection with the Transactions have been outstanding for the entirety of the year presented.  

Pro forma weighted-average shares outstanding, basic and diluted, are calculated as follows for the three months ended March 31, 2026 and the year ended December 31, 2025:

(in thousands, except share and per share data)	For the Three Months Ended March 31, 2026			For the Year Ended December 31, 2025
