CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q contains “forward-looking statements.” Forward-looking statements include, but are not limited to, statements that express our intentions, beliefs, expectations, strategies, predictions or any other statements relating to our future activities or other future events or conditions. These statements are based on current expectations, estimates and projections about our business based, in part, on assumptions made by management. These statements are not guarantees of future performance and involve risks, uncertainties and assumptions that are difficult to predict. Therefore, actual outcomes and results may, and are likely to, differ materially from what is expressed or forecasted in the forward-looking statements due to numerous factors discussed from time to time in this Report and in other documents which we file with the Securities and Exchange Commission (the “SEC”). In addition, such statements could be affected by risks and uncertainties related to:

	●	our independent registered public accounting firm’s report includes an explanatory paragraph stating that there is substantial doubt about our ability to continue as a going concern;

	●	our need for substantial additional funds and our ability to raise those funds;

	●	our ongoing evaluation of strategic alternatives;

	●	our ability to successfully commercialize LYMPHIR, including covering the costs of licensing payments, product manufacturing and other third-party goods and services;

	●	our ability to regain compliance with the continued listing requirements of the Nasdaq Stock Market LLC (“Nasdaq”);

	●	the ability of LYMPHIR or any of our future product candidates to impact the quality of life of our target patient populations;

	●	the estimated markets for LYMPHIR or any of our future product candidates and the acceptance thereof by any market;

	●	our ability to recognize the anticipated benefits of the August 2024 reverse merger whereby we became a standalone publicly-traded company and majority-owned subsidiary of Citius Pharmaceuticals, Inc. (“Citius Pharma”), which may not be realized fully, if at all, or may take longer to realize than expected;

	●	our ability to procure cGMP commercial-scale supply;

	●	our ability to obtain, perform under and maintain financing and strategic agreements and relationships;

	●	our ability to manage and grow our business and execution of our business and growth strategies;

	●	our ability to recruit and retain qualified management and technical personnel to carry out our operations; and

	●	the other factors discussed in the “Risk Factors” section of our most recent Annual Report on Form 10-K for the fiscal year ended September 30, 2025, filed with the SEC on December 23, 2025.

Any forward-looking statements speak only as of the date on which they are made, and except as may be required under applicable securities laws, we do not undertake any obligation to update any forward-looking statement to reflect events or circumstances after the filing date of this Report.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

FOR THE Nine months Ended June 30, 2026 and 2025

(Unaudited)

1. NATURE OF OPERATIONS, BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Business

Citius Oncology, Inc. (“Citius Oncology”, the “Company”, “we” or “us”) is a specialty pharmaceutical company dedicated to the development and commercialization of critical care products targeting unmet needs with a focus on oncology products. We have developed E7777 (denileukin diftitox), an approved oncology immunotherapy for the treatment of cutaneous T-cell lymphoma (“CTCL”), a rare form of non-Hodgkin lymphoma. We have obtained the trade name of LYMPHIR for E7777. Revenue commenced in December 2025 with the commercial launch of LYMPHIR.

Since our inception, we have devoted substantially all our efforts to business planning, research and development, and recruiting management and technical staff. We are subject to a number of risks common to companies in the pharmaceutical industry including, but not limited to, the Company’s ability to obtain additional financing, risks related to the development by the Company or its competitors of research and development stage products, market acceptance of any of its products approved for marketing, competition from larger companies, dependence on key personnel, dependence on key suppliers and strategic partners and the Company’s compliance with governmental and other regulations.

Since our inception, Citius Pharmaceuticals, Inc. (“Citius Pharma”) (Nasdaq: CTXR) has funded and continues to partially fund the Company. Citius Pharma and the Company are party to an amended and restated shared services agreement (the “A&R Shared Services Agreement”), which governs certain management and scientific services that Citius Pharma provides the Company.

Merger

On August 23, 2021, Citius Pharma formed Citius Acquisition Corp. (“SpinCo”) as a wholly-owned subsidiary in conjunction with the acquisition of LYMPHIR, which began operations in April 2022, when Citius Pharma transferred the assets related to LYMPHIR to SpinCo, including the related license agreement and asset purchase agreement (see Note 7).

On October 23, 2023, Citius Pharma and SpinCo entered into an agreement and plan of merger and reorganization (the “Merger Agreement”) with TenX Keane Acquisition, a Cayman Islands exempted company (“TenX”), and TenX Merger Sub Inc., a Delaware corporation and a wholly owned subsidiary of TenX (“Merger Sub”).

On August 12, 2024, pursuant to the terms and conditions of the Merger Agreement, Merger Sub merged with and into SpinCo, with SpinCo surviving as a wholly owned subsidiary of TenX (the “Merger”) which was subsequently renamed Citius Oncology Sub, Inc. Prior to closing of the Merger, TenX migrated to and domesticated as a Delaware corporation in accordance with Section 388 of the General Corporation Law of the State of Delaware and the Cayman Islands Companies Act (As Revised) (the “Domestication”). As part of the Domestication, TenX changed its name to “Citius Oncology, Inc.” (Nasdaq: CTOR). Immediately after the closing of the Merger, Citius Pharma owned approximately 92% of the outstanding shares of common stock of the Company. As of June 30, 2026, Citius Pharma owned approximately 62% of the outstanding shares of common stock of the Company.

While the Merger Sub was the legal acquirer of the Company, for accounting purposes, the Company was deemed to be the accounting acquirer. Accordingly, for accounting purposes, the Merger was treated as the equivalent of the Company issuing stock for the assets and liabilities of the Merger Sub, accompanied by a recapitalization. Total shares outstanding of the Company after the Merger and recapitalization increased to 71,552,402. The net assets of the merged entities are stated at historical cost, with no goodwill or other intangible assets recorded. Additionally, the historical financial statements of SpinCo became the historical financial statements of the Company.

The Merger, net amount of $2,753,795 charged to additional paid-in capital consists of $395,015 of net liabilities of TenX on the date of the Merger plus directly related transaction costs of $2,358,780.

As part of the Merger, Citius Pharma made capital investments in the Company through cash contributions of $3,827,944 to fund transactions related to the Merger and by reclassifying to additional paid-in capital intercompany receivables of $33,180,961 that were due from the Company to Citius Pharma. Simultaneously, Citius Pharma advanced an additional $3,800,111 to the Company under the terms of a note payable (see Note 11).

Basis of Presentation and Summary of Significant Accounting Policies

Basis of Preparation - The accompanying unaudited condensed consolidated financial statements include the operations of Citius Oncology, Inc., and its wholly-owned subsidiary, Citius Oncology Sub, Inc., which was formed in connection with Merger. All significant inter-company balances and transactions have been eliminated in consolidation.

The accompanying unaudited condensed consolidated financial statements of the Company have been prepared on the same basis as the annual consolidated financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary to fairly state the condensed consolidated financial position of the Company as of June 30, 2026, and the results of its operations and cash flows for the three and nine months ended June 30, 2026 and 2025. The operating results for the three and nine months ended June 30, 2026 are not necessarily indicative of the results that may be expected for the year ending September 30, 2026. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2025 filed with the Securities and Exchange Commission (“SEC”) on December 23, 2025.

Use of Estimates - The process of preparing financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of financial statements and the reported amounts of revenues and expenses during the reporting period. Estimates having relatively higher significance include the accounting for revenue recognition, in-process research and development, stock-based compensation, net realizable value of inventory and income taxes. Actual results could differ from those estimates and changes in estimates may occur.

Basic and Diluted Net Loss per Common Share - Basic and diluted net loss per common share applicable to common stockholders is computed by dividing net loss applicable to common stockholders in each period by the weighted average number of shares of common stock outstanding during such period. For the periods presented, common stock equivalents, consisting of stock options and warrants, were not included in the calculation of the diluted loss per share because they were anti-dilutive, with pre-funded warrants being included in the loss per share.

Recently Issued Accounting Standards

Other than as disclosed in our Form 10-K, we are not aware of any other recently issued accounting standards not yet adopted that may have a material impact on our financial statements.

2. GOING CONCERN UNCERTAINTY AND MANAGEMENT’S PLAN

The accompanying unaudited condensed consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The Company had a net loss of $41,067,610 for the nine months ended June 30, 2026. The Company has generated limited revenue, which commenced in December 2025, and had historically relied primarily on funding from Citius Pharma to finance its operations. At June 30, 2026, the Company had $16,563,705 in cash and a negative working capital of $16.1 million.

On May 5, 2026, Citius Oncology received net proceeds of approximately $9.7 million from the exercise of certain warrants (See Note 9).

The Company entered into a term loan agreement with two lenders for up to $25.0 million, with $10.0 million funded on May 6, 2026, up to $7.0 million available between October 1 and December 31, 2026, if certain net revenue and liquidity milestones are achieved, and up to $8.0 million available between January 1 and March 31, 2027, if certain additional net revenue milestones are achieved and a loan was drawn between October 1 and December 31, 2026. The loans bear interest at the greater of the prime rate plus 6% or 12.75% and are secured by all of the Company’s assets, subject to agreed exceptions. The loans mature on November 1, 2029 (See Note 8). We expect that we and Citius Pharma will have sufficient funds to continue our operations through November 2026. We will need to raise additional capital to support our operations beyond November 2026, which raises substantial doubt about our ability to continue as a going concern within one year after the date that the accompanying financial statements are issued.

The Company plans to continue to rely partially on funding from Citius Pharma, to raise capital through equity and debt financings, and to generate revenue from sales of LYMPHIR. Both the Company and Citius Pharma are actively engaged in capital raising efforts to extend the cash runway. The Company also has retained Jefferies LLC as its exclusive financial advisor in evaluating strategic alternatives aimed at maximizing shareholder value. There is no assurance, however, that Citius Pharma will have the resources to assist in funding the Company, that the Company will be successful in meeting the net revenue and liquidity milestones required under the loan agreement, or raising the needed capital and, if funding is available, that it will be available on terms acceptable to the Company or that the Company will find strategic partners or generate substantial revenue from the sale of LYMPHIR. The accompanying unaudited condensed consolidated financial statements do not include any adjustments that might result from the outcome of the above uncertainty.

3. REVENUE RECOGNITION AND ACCOUNTS RECEIVABLE

Revenue Recognition

We recognize revenue in accordance with the provisions of Accounting Standards Codification Topic 606, Revenue from Contracts with Customers. In determining the appropriate amount and timing of revenue to be recognized under this guidance, we perform the following five steps: (i) identify the contract(s) with our customer; (ii) identify the promised goods or services in the agreement and determine whether they are performance obligations, including whether they are distinct in the context of the agreement; (iii) measure the transaction price, including the constraint on variable consideration; (iv) allocate the transaction price to the performance obligations based on stand-alone selling prices; and (v) recognize revenue when (or as) we satisfy each performance obligation. Revenues are recognized when control of the promised goods or services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services.

We distribute LYMPHIR in the U.S. through third party specialty distributors who are our customers. The third-party specialty distributors subsequently resell our product to health care providers, hospitals and infusion centers. Separately, we have or may enter into payment arrangements with various third-parties including government healthcare programs who provide coverage and or reimbursement for our product that have been prescribed to a patient. Through a regional distribution partner, we distribute LYMPHIR internationally as part of our Named Patient Program.

Net Revenues

We recognize net revenue from LYMPHIR sales, net of variable consideration and consideration payable to parties other than our customers consisting of estimates related to allowances for sales returns, government chargebacks, patient coupon programs, and specialty distributor fees. Revenue is generally recognized when the customer obtains control of the Company’s product, which occurs at a point in time, upon delivery based on the contractual shipping terms of a contract.

We estimate variable consideration using the expected value method, constrained to amounts for which it is probable that a significant reversal of cumulative revenue will not occur when uncertainties are resolved. Calculating certain of these items involves estimates and judgments based on sales or invoice data, contractual terms, historical or expected utilization rates, new information regarding changes in applicable regulations and guidelines that would impact the amount of the actual allowance and our expectations regarding future utilization rates and channel inventory data. We review the adequacy of our provisions for all gross-to-net adjustments on a quarterly basis. Amounts reserved for these adjustments are made when trends or significant events indicate that adjustment is appropriate reflecting actual experience.

The Company elected the practical expedient in ASC 606-10-32-18 and does not assess whether a significant financing component exists for contracts in which payment is expected within one year. No other practical expedients were applied.

Gross-to-Net Adjustments

Specialty Distributor Fees

We pay fees for distribution services, such as fees for certain data that customers provide us. We estimate our customers will earn these fees and deduct these fees from gross product revenues at the time we recognize the related revenues.

Product Returns

Customers have the right to return products if they are damaged, defective, or expired, or as it is defined in their customer agreement. We have estimated product returns considering experience from similar products in the market, historical return patterns, sales data, and inventory levels in the distribution channel. These reserves are recorded in the same period the related revenue is recognized, resulting in a reduction of gross product revenue.

Chargebacks

Chargebacks will occur when federal agencies who we contract with, or may contract with, can purchase off the Federal Supply Schedule or when Public Health Service 340B covered entities purchase directly from our customers at discounted prices. Our customers then charge us the difference between their purchase price and the discounted price. We estimate chargebacks considering the terms of the applicable arrangement and our visibility regarding utilization. We record estimates for these chargebacks at the time of sale as deductions from gross product revenues, with corresponding adjustments to our accounts receivable reserves and allowances.

Co-payment Assistance

We offer co-payment assistance to patients with commercial insurance that have coverage and are allowed such co-payment assistance. We estimate the average co-payment assistance amounts for our products based on expected customer utilization and record estimates as a reduction from gross product revenue. The Company has deposited the estimated co-pay assistance amounts, which are reflected and included in the gross-to-net adjustments.

	Three Months Ended		Nine Months Ended
	June 30, 2026		June 30, 2026

Gross Product Revenue	$	1,708,560	$	8,591,040
Gross-to-net adjustments		214,772		1,485,843
Net Revenue	$	1,493,788	$	7,105,197

Accounts receivable

Accounts receivable is stated at amounts invoiced less allowances for distributor fees, chargebacks, and estimated returns. At June 30, 2026, these sales allowances totaled $690,090. On a periodic basis, the Company evaluates its accounts receivable to establish an allowance for doubtful accounts. The allowance reflects our current estimate of credit losses expected to occur over the life of the receivable. In developing our allowance for expected credit losses, we use assumptions to capture the risk of loss, even if remote, based on a number of factors including existing contractual payment terms, individual customer circumstances, historical payment patterns of our customers, a review of the local economic environment and its potential impact on expected future customer payment patterns. Our collection risk is mitigated to a certain extent by the fact that sales are collected in a reasonable period of time, allowing for the ability to reduce exposure on defaults if collection issues are identified. We update our allowance as necessary to reflect expected credit losses over the remaining accounts receivable that are past due. We do not currently expect our current or future exposures to credit losses to have a significant impact on us. The estimated allowance for expected credit losses was $0 as of June 30, 2026.

4. INVENTORY

Inventory is stated at the lower of actual accumulated costs or net realizable value related to the manufacturing of LYMPHIR commercial products, which became available for sale in December 2025. Cost is determined using the first-in, first-out (FIFO) method. No reserves against inventory were deemed necessary based on an evaluation of the product expiration dating. A summary of inventory is as follows:

	June 30, 2026		September 30, 2025
Finished goods	$	15,673,980	$	10,577,876
Work in process		6,951,965		11,708,817
Total	$	22,625,945	$	22,286,693

Cost of Revenues

Cost of goods sold consists of direct and indirect costs associated with manufacturing and distributing LYMPHIR. These costs include amounts paid to third-party contract manufacturing organizations for production-related services, including raw materials, drug substance, drug product manufacturing, fill-finish activities, certain testing, and packaging. Cost of goods sold also includes distribution, storage shipping, and handling fees, as well as royalties owed under the Company’s licensing arrangements.

5. PREPAID EXPENSES

7. PATENT AND TECHNOLOGY LICENSE AGREEMENTS

License Agreement with Eisai

In September 2021, Citius Pharma entered into an asset purchase agreement with Dr. Reddy’s Laboratories SA, a subsidiary of Dr. Reddy’s Laboratories, Ltd. (collectively, “Dr. Reddy’s”) and a license agreement with Eisai Co., Ltd. (“Eisai”) to acquire an exclusive license of E7777 (denileukin diftitox), an oncology immunotherapy for the treatment of CTCL, a rare form of non-Hodgkin lymphoma. Citius Pharma renamed E7777 as I/ONTAK and also obtained the trade name LYMPHIR^TM for the product. Citius Pharma assigned these agreements to us effective April 1, 2022. The Company received a Biologics License Application (“BLA”) approval from the FDA for LYMPHIR in August 2024.

Under the terms of these agreements, Citius Pharma acquired Dr. Reddy’s exclusive license of E7777 from Eisai and other related assets owned by Dr. Reddy’s (which are now owned by Citius Oncology). The exclusive license includes rights to develop and commercialize E7777 in all markets except for Japan and certain parts of Asia. Eisai retains exclusive development and marketing rights for the agent in Japan, China, Korea, Taiwan, Hong Kong, Macau, Indonesia, Thailand, Malaysia, Brunei, Singapore, India, Pakistan, Sri Lanka, Philippines, Vietnam, Myanmar, Cambodia, Laos, Afghanistan, Bangladesh, Bhutan, Nepal, Mongolia, and Papua New Guinea. Citius Pharma paid Dr. Reddy’s a $40 million upfront payment, which represents the acquisition date fair value of the in-process research and development acquired from Dr. Reddy’s. Dr. Reddy’s is entitled to up to $40 million in development milestone payments related to CTCL approvals in the U.S. and other markets, up to $70 million in development milestones for additional indications, as well as commercial milestone payments and low double-digit tiered royalties on net product sales (within a range of 10% to 15%), and up to $300 million for commercial sales milestones. Citius Oncology also must pay on a fiscal quarter basis tiered royalties equal to low double-digit percentages of net product sales (within a range of 10% to 15%). The royalties will end on the earlier of (i) the 15-year anniversary of the first commercial sale of the latest indication that received regulatory approval in the applicable country and (ii) the date on which a biosimilar product results in the reduction of net sales in the applicable product by 50% in two consecutive quarters, as compared to the four quarters prior to the first commercial sale of the biosimilar product. Citius Oncology will also pay to Dr. Reddy’s an amount equal to a low-thirties percentage of any sublicense upfront consideration or milestone payments (or the like) received by us and the greater of (i) a low-thirties percentage of any sublicensee sales-based royalties or (ii) a mid-single digit percentage of such licensee’s net sales. Citius Pharma is a guarantor of Citius Oncology’s payment obligations under these agreements.

At the time of the FDA approval for LYMPHIR, a $27.5 million milestone payment became payable to Dr. Reddy’s under the terms of the asset purchase agreement for which a balance of $15,650,000 remains due as of June 30, 2026. Dr. Reddy’s agreed to a partial deferral without penalty of this milestone payment.

Under the license agreement, Eisai was due a $5.9 million milestone payment upon FDA approval, and additional commercial milestone payments related to the achievement of net product sales thresholds and an aggregate of up to $22 million related to the achievement of net product sales thresholds. Citius Oncology was also required to reimburse Eisai for up to $2.65 million of its costs to complete the Phase 3 pivotal clinical trial for LYMPHIR for the CTCL indication and reimburse Eisai for all reasonable costs associated with the preparation of a BLA for LYMPHIR. Eisai was responsible for completing the CTCL clinical trial, and chemistry, manufacturing, and controls (“CMC”) activities through the filing of the BLA for LYMPHIR with the FDA. We are responsible for development costs associated with potential additional indications.

On March 28, 2025, Citius Oncology and Eisai entered into a letter agreement that amended the license agreement to provide for a payment schedule to Eisai for the milestone payment and certain unpaid invoices. We agreed to pay Eisai $2,535,318 on July 15, 2025, $2,350,000 on the 15^th of each of the subsequent four months, and make a final payment of $2,197,892 on or before December 15, 2025, in each case with interest on each obligation from its original due date through the date of payment at the rate of 2% per annum. During the nine months ended June 30, 2026, we recorded $112,270 in interest expense under the agreement. The parties released each other from any and all claims, losses, damages, costs and expenses that arise from or related to our failure to pay the milestone payment or the other incurred costs under the license agreement except for any claims arising out of a breach of the letter agreement. All other terms of the license agreement remain in full force and effect. On December 15, 2025, we paid Eisai the balance of the outstanding milestone approval fee and accumulated interest on the license fee. On March 30, 2026 we paid Eisai $500,000 against the accounts payable balance. At June 30, 2026, we owe Eisai for other unpaid invoices, consisting of $2,200,000 of accounts payable and $4,062,481 of accrued expenses.

The term of the license agreement will continue until the 10-year anniversary of the first commercial sale on a country-by-country basis. The first commercial sale in the United States occurred in December 2025. The term of the license may be extended for additional 10-year periods for all countries in the territory by notifying Eisai and paying an extension fee equal to $10 million. Either party may terminate the license agreement upon written notice if the other party is in material breach of the agreement, subject to cure within the designated time periods. Either party also may terminate the license agreement immediately upon written notice if the other party files for bankruptcy or takes related actions or is unable to pay its debts as they become due. Additionally, either party will have the right to terminate the agreement if the other party directly or indirectly challenges the patentability, enforceability or validity of any licensed patent.

Under the purchase agreement with Dr. Reddy’s, we are required to (i) use commercially reasonable efforts to make commercially available products in the CTCL indication, peripheral T-cell lymphoma indication and immuno-oncology indication, (ii) initiate two investigator initiated immuno-oncology trials (both of which have been initiated), (iii) use commercially reasonable efforts to achieve each of the approval milestones, and (iv) complete each specified immuno-oncology investigator trial on or before the four-year anniversary of the effective date of the definitive agreement. Additionally, we are required to commercially launch a product in a territory within six months of receiving regulatory approval for such product in each such jurisdiction; though approved in August 2024, Dr. Reddy’s waived the six-month requirement and the launch of LYMPHIR in December 2025 satisfied this requirement in the U.S.

As part of the definitive agreement with Dr. Reddy’s, Citius Pharma acquired method of use patents in which LYMPHIR is administered in combination with the programmed cell death protein 1 (“PD-1”) pathway inhibitor drug class. PD-1 plays a vital role in inhibiting immune responses and promoting self-tolerance through modulating the activity of T-cells, activating apoptosis of antigen-specific T cells and inhibiting apoptosis of regulatory T cells.

The following patents were acquired and subsequently transferred to us:

●

US Provisional Application No. 63/070,645, which was filed on August 26, 2020, and subsequently published as US 2022/0062390 A1 on March 3, 2022, entitled Methods of Treating Cancer.

●

International Patent Application Number: PCT/IB2021/0576733, which was filed with the World Intellectual Property Organization on August 23, 2021, and subsequently published as WO 2022/043863 A1 on March 3, 2022, entitled, Combination for Use in Methods of Treating Cancer.

We amended the 2024 Plan on October 27, 2025 to reserve an additional 15,000,000 shares of common stock for an aggregate of 30,000,000 shares of common stock. The stock plans provide incentives to employees, directors, and consultants through grants of options, SARs, dividend equivalent rights, restricted stock, restricted stock units, or other rights.

The fair value of each stock option award is estimated on the date of grant using the Black-Scholes option pricing model. Volatility is estimated using the trading activity of Citius Pharma common stock until such time as we have sufficient history. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant commensurate with the expected term assumption. The expected term of stock options granted to employees and directors, all of which qualify as “plain vanilla,” is based on the average of the contractual term (generally 10 years) and the vesting period. For non-employee options, the expected term is the contractual term.

A summary of option activity under the stock plans is presented below:

	Shares		Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term	Aggregate Intrinsic Value

10. COMMERCIAL MANUFACTURING CONTRACTS

The Company had previously entered into an agreement with a contract manufacturing organization, (“CMO”) for the manufacture and supply of bulk drug substance, (“BDS”) with the agreement continuing through calendar year 2026. The agreement was terminated effective February 2026 by the CMO due to the breach of payment obligations by the Company. Termination fees associated with this are approximately $20.1 million consisting of $17.1 million of charges associated with manufacturing which was previously committed in 2025 and 2026 but not produced, as well as $1.2 million of un-invoiced but incurred charges related to previous manufactured batches and $1.8 million of interest and other charges. These fees are included in general and administrative expenses for the nine months ended June 30, 2026. Separately, in March 2026 the CMO gave notice that it made a decision to terminate all production at the current site related to microbial manufacturing and decommission the associated manufacturing lines. In March 2026 and in connection with the notice of termination from the CMO, we recorded a contract cancellation fee of $19,733,307 net of invoices already included in accounts payable.

In June 2026, the Company entered into a letter of intent with a new CMO for the purposes of supplying BDS and expects to enter into a master services agreement. At this time, based on stock on hand and availability of alternate suppliers, we anticipate no interruption in commercial supply for the foreseeable future.

As of June 30, 2026, the Company also has commercial supply agreements with two other vendors for the completion and packaging of finished drug products. Minimum purchase commitments under these two agreements amount to approximately $4.0 million consisting of purchase commitment obligations of $2.2 million in calendar year 2026 and $1.8 million in calendar year 2027.

11. RELATED PARTY TRANSACTIONS

Our officers and directors also serve as officers of Citius Pharma. As of June 30, 2026, the Company does not have any employees.

Through March 31, 2026, we had limited cash, therefore most of our expenditures were paid by Citius Pharma and reflected in the due to related party account.

Citius Pharma advanced cash to us for a non-interest bearing, unsecured promissory note, dated August 16, 2024, in the principal amount of $3,800,111, which was subsequently amended. As amended, the note was repayable in full upon a financing of at least $50 million by us. On May 4, 2026, the Company and Citius Pharma, entered into another amendment to the note in connection with the loan agreement (see Note 8), such that the note is payable 91 days after the debt under the loan agreement has been paid and the loan agreement has been terminated, prohibits prepayment of the note in cash, and adds a conversion feature allowing Citius Pharma, subject to the Company’s approval, to convert all or a portion of the outstanding principal into shares of common stock at a conversion price equal to $0.90 per share.

12. GAIN ON SALE OF NEW JERSEY NET OPERATING LOSSES

We recognized a gain of $1,762,000 for the nine months ended June 30, 2026, in connection with the sale of certain New Jersey income tax net operating losses to a third party under the New Jersey Technology Business Tax Certificate Transfer Program.

13. NASDAQ LISTING

On April 22, 2026, we received a notification letter from the Nasdaq Stock Market LLC (“Nasdaq”) indicating that we were not in compliance with Nasdaq Listing Rule 5550(a)(2) because the minimum bid price of our common stock on the Nasdaq Capital Market closed below $1.00 per share for 30 consecutive business days. In accordance with Nasdaq Listing Rule 5810(c)(3)(A), the Company has a compliance period of 180 calendar days, or until October 19, 2026, to regain compliance with the Bid Price Rule.

The following discussion contains “forward-looking statements” that reflect our future plans, estimates, beliefs and expected performance. Our actual results may differ materially from those currently anticipated and expressed in such forward-looking statements as a result of a number of factors. We caution that assumptions, expectations, projections, intentions, or beliefs about future events may, and often do, vary from actual results and the differences can be material. Please see “Cautionary Note Regarding Forward-Looking Statements” on page iii of this Report.

Business

Citius Oncology is a specialty biopharmaceutical company focused on developing and commercializing innovative targeted oncology therapies. We have developed E7777 (denileukin diftitox), an approved oncology immunotherapy for the treatment of cutaneous T-cell lymphoma (“CTCL”), a rare form of non-Hodgkin lymphoma. We have obtained the trade name of LYMPHIR for E7777 and revenue commenced in December 2025 upon the commercial launch of LYMPHIR.

We were incorporated in the Cayman Islands on March 1, 2021, for the purpose of effecting a business combination with one or more businesses. In August 2024, we reincorporated in Delaware and completed the Merger whereby we acquired SpinCo as a wholly owned subsidiary and changed our name to Citius Oncology, Inc. SpinCo began operations in April 2022.

Since inception, we have devoted substantially all of our efforts to business planning, research and development, recruiting management and technical staff and commercially launching LYMPHIR. We are subject to a number of risks common to companies in the pharmaceutical industry including, but not limited to, our ability to obtain additional financing, risks related to the development by us or our competitors of research and development stage products, market acceptance of our approved products, competition from larger companies, dependence on key personnel, dependence on key suppliers and strategic partners, and our compliance with governmental and other regulations.

License Agreement with Eisai

In September 2021, Citius Pharma entered into an asset purchase agreement with Dr. Reddy’s and a license agreement with Eisai to acquire an exclusive license of E7777 (denileukin diftitox), an oncology immunotherapy for the treatment of CTCL, a rare form of non-Hodgkin lymphoma. Citius Pharma renamed E7777 as I/ONTAK and also obtained the trade name LYMPHIR^TM for the product. Citius Pharma assigned these agreements to us effective April 1, 2022. Denileukin diftitox is referred to in this report as E7777, I/ONTAK or LYMPHIR, depending on the period of time and context that is being discussed.

Under the terms of these agreements, Citius Pharma acquired Dr. Reddy’s exclusive license of E7777 from Eisai and other related assets owned by Dr. Reddy’s which are now owned by us. The exclusive license includes rights to develop and commercialize E7777 in all markets except for Japan and certain parts of Asia. Eisai retains exclusive development and marketing rights for the agent in Japan, China, Korea, Taiwan, Hong Kong, Macau, Indonesia, Thailand, Malaysia, Brunei, Singapore, India, Pakistan, Sri Lanka, Philippines, Vietnam, Myanmar, Cambodia, Laos, Afghanistan, Bangladesh, Bhutan, Nepal, Mongolia, and Papua New Guinea. Citius Pharma paid Dr. Reddy’s a $40 million upfront payment, which represents the acquisition date fair value of the in-process research and development acquired from Dr. Reddy’s. Dr. Reddy’s is entitled to up to $40 million in development milestone payments related to CTCL approvals in the U.S. and other markets, up to $70 million in development milestones for additional indications, as well as commercial milestone payments and low double-digit tiered royalties on net product sales (within a range of 10% to 15%), and up to $300 million for commercial sales milestones. We also must pay on a fiscal quarter basis tiered royalties equal to low double-digit percentages of net product sales (within a range of 10% to 15%). The royalties will end on the earlier of (i) the 15-year anniversary of the first commercial sale of the latest indication that received regulatory approval in the applicable country and (ii) the date on which a biosimilar product results in the reduction of net sales in the applicable product by 50% in two consecutive quarters, as compared to the four quarters prior to the first commercial sale of the biosimilar product. We will also pay Dr. Reddy’s an amount equal to a low-thirties percentage of any sublicense upfront consideration or milestone payments (or the like) received by us and the greater of (i) a low-thirties percentage of any sublicensee sales-based royalties or (ii) a mid-single digit percentage of such licensee’s net sales. Citius Pharma is a guarantor of our payment obligations under these agreements.

At the time of the FDA approval for LYMPHIR, a $27.5 million milestone payment became payable to Dr. Reddy’s under the terms of the asset purchase agreement for which a balance of $15.65 million remains due as of June 30, 2026. Dr. Reddy’s agreed to a partial deferral without penalty of this milestone payment.

Under the license agreement, Eisai was due a $5.9 million milestone payment upon FDA approval, and additional commercial milestone payments related to the achievement of net product sales thresholds and an aggregate of up to $22 million related to the achievement of net product sales thresholds. We were also required to reimburse Eisai for up to $2.65 million of its costs to complete the Phase 3 pivotal clinical trial for LYMPHIR for the CTCL indication and reimburse Eisai for all reasonable costs associated with the preparation of a BLA for LYMPHIR. Eisai was responsible for completing the CTCL clinical trial, and CMC activities through the filing of the BLA for LYMPHIR with the FDA. We are responsible for development costs associated with potential additional indications.

On March 28, 2025, Citius Oncology and Eisai entered into a letter agreement that amended the license agreement to provide for a payment schedule to Eisai for the milestone payment and certain unpaid invoices. We agreed to pay Eisai $2,535,318 on July 15, 2025, $2,350,000 on the 15^th of each of the subsequent four months, and make a final payment of $2,197,892 on or before December 15, 2025, in each case with interest on each obligation from its original due date through the date of payment at the rate of 2% per annum. During the nine months ended June 30, 2026, we recorded $112,270 in interest expense under the agreement. The parties released each other from any and all claims, losses, damages, costs and expenses that arise from or related to our failure to pay the milestone payment or the other incurred costs under the license agreement except for any claims arising out of a breach of the letter agreement. All other terms of the license agreement remain in full force and effect. On December 15, 2025, we paid Eisai the balance of the outstanding milestone approval fee and accumulated interest on the license fee. At June 30, 2026, we owe Eisai approximately $6.3 million for certain other unpaid invoices.

Recent Events

Commercial Launch Activities

On March 31, 2026, we provided an update on the U.S. commercial launch of LYMPHIR, highlighting continued adoption across leading oncology centers, broad payer coverage progress, and advancing investigator-led clinical studies. We expect continued expansion in prescribing activity, together with further clinical validation through ongoing investigator-led studies. These trends support LYMPHIR’s potential not only for continued integration in the CTCL treatment landscape, but also its potential as a part of a combination immunotherapy regimen in other cancers.

Key Early Launch Metrics:

●

Growth in orders from target institutions since launch, with initial accounts placing repeat orders;

●

Strong institutional uptake, with 83% of target accounts having added or actively progressing LYMPHIR through formulary review;

●

Broad and expanding market access with 135 health plans representing 80% of covered lives, secured and reimbursement systems established;

●

No reported reimbursement denials or prior authorization barriers;

●

Increasing demand for product education;

●

Initial penetration into community infusion centers underway with patients beginning to transition from larger cancer centers;

●

Commercial buildout proceeding, with field team onboarding and expansion in progress with our contracted sales organization; and

●

Commercial supply remains well positioned to support anticipated U.S. demand, and international expansion.

On April 29, 2026, we announced the initial shipment of LYMPHIR to Europe through a regional distribution partner, marking an important milestone in expanding access to the therapy for patients outside the US. LYMPHIR will be made available to eligible patients through Named Patient Programs in accordance with local regulations in each country. The initiation of European distribution represents a strategic step in our effort to extend access to LYMPHIR.

On July 21, 2026 and through our exclusive commercialization partner EVERSANA, we announced the expansion of our commercial organization to include 21 additional commercial field-based professionals and the addition of eight medical science liaisons dedicated to supporting complex clinical practitioner engagement and patient care. All personnel were expected to be fully onboarded and deployed nationwide by August 2026, which target date was met. The expansion of the commercial and medical teams was facilitated by our May 2026 financing and implemented by EVERSANA. EVERSANA also provides Citius Oncology with an integrated suite of operations services including medical information, pharmacovigilance, revenue cycle management, program management, data and analytics, channel management, and patient assistance.

On August 14, 2026, we provided an update on the U.S. commercial launch of LYMPHIR highlighting increased institutional availability for LYMPHIR, accelerating institutional vial orders and the expansion to a full commercial field organization.

Mid-Year Launch Metrics:

●

44 institutions have ordered LYMPHIR since its launch including; academic oncology centers, leading National Comprehensive Cancer Network (NCCN) institutions, and community infusion centers;

●

Increased the number of new ordering institutions by 80% in the quarter ended June 30, 2026 compared to the quarter ended March 31, 2026;

●

Grew the number of vials ordered by institutions from wholesalers by 31% in the quarter ended June 30, 2026, compared to the quarter ended March 31, 2026, 926 vs. 708 vials respectively;

●

383 institutional vial orders of LYMPHIR were placed in July, an increase of 25% vs. the prior quarters average;¹

●

Expanded the commercial organization by 21 additional field-based professionals and added eight medical science liaisons, executed by the Company’s exclusive commercialization partner, EVERSANA;

●

Engaged U.S. and international CTCL key opinion leaders at the Sixth World Congress of Cutaneous Lymphomas in Montreal through scientific exchange and educational initiatives; and

●

Continued to near-universal payer coverage, with no reimbursement denials or prior authorization barriers reported to date.

Institutional vial orders are vials of LYMPHIR ordered by prescribing institutions from wholesalers. Citius Oncology recognizes revenue when LYMPHIR vails are ordered from Citius Oncology by wholesalers.

US Distribution Agreements

In 2025, the Company executed three service agreements with U.S. pharmaceutical specialty distributors who are our customers and who distribute LYMPHIR to healthcare organizations which include academic centers, community oncology practices, as well as infusion centers. The transaction price for gross product revenues under these customer specialty distributor agreements are based on the contractually stated wholesale acquisition cost (“WAC”). The transaction price is reduced for variable considerations, including product returns, chargebacks, co-payment assistance, and other gross-to-net adjustments, which are reasonably estimated by the Company and constrained to amounts that are probable not to result in a significant revenue reversal. As LYMPHIR is a newly launched product, any reasonable estimates made by the Company regarding certain gross-to-net adjustments will result from certain information, such as inventory held by distributors, market data or comparable products, until sufficient historical data becomes available.

International Distribution Agreements

On October 7, 2025, we entered into an exclusive distribution agreement with Integris Pharma S.A., headquartered in Athens, Greece to make LYMPHIR available to eligible patients through country-specific Named Patient Programs (NPPs). The partnership covers Greece, Cyprus, Malta, Bulgaria, Romania, Croatia, Serbia, Albania, Bosnia Herzegovina, Kosovo, Montenegro and North Macedonia. NPPs are formally recognized pathways designed to give patients earlier access to promising new medicines in advance of full marketing authorization and commercial availability in markets outside the US. Under these programs, a treating physician may request a therapy for an individual patient when no adequate approved alternatives exist. In doing so, NPPs bridge a critical gap between the completion of clinical trials in each region and broad market introduction, ensuring that patients with serious illnesses are not left waiting for life-extending innovations. These programs provide access, where permitted by local law, and do not constitute commercial approval of LYMPHIR outside the U.S.

On December 4, 2025, we announced an exclusive distribution agreement with Er-Kim İlaç Sanayi ve Ticaret A.Ş. (“Er-Kim”), a leading pharmaceutical distributor based in Turkey, for LYMPHIR. Under the agreement, Er-Kim will be the exclusive distributor of LYMPHIR in Turkey and key Gulf Cooperation Council (GCC) countries, including Bahrain, Qatar, Oman, Kuwait, Saudi Arabia, and the United Arab Emirates.

On February 11, 2026, we announced an exclusive distribution agreement with Uniphar (“Uniphar”), a leading international healthcare services company, to support access to LYMPHIR. Under the agreement, Uniphar will serve as our exclusive distribution partner in designated international territories in Western and Eastern Europe. We will supply finished product and provide ongoing support in accordance with the agreement. LYMPHIR is not approved for commercial use outside the U.S. and will be provided solely through country-specific managed access programs, which do not constitute marketing authorization or a commercial launch.

Investigator Initiated Trials

On March 4, 2026, we announced positive topline safety and efficacy results from an investigator-initiated Phase 1 trial evaluating LYMPHIR administered prior to commercial CD19 directed CAR T therapy in patients with high risk relapsed or refractory diffuse large B cell lymphoma (DLBCL).

On March 10, 2026, we announced positive topline results from a completed investigator-initiated Phase 1 clinical trial conducted by University of Pittsburgh investigators. This study evaluated the direct T-regulatory (Treg) cell depletion activity of LYMPHIR in combination with the PD-1 immune checkpoint inhibitor pembrolizumab (KEYTRUDA^®) in patients with recurrent or refractory gynecologic cancers, including ovarian and endometrial malignancies.

Discussions are ongoing regarding next-stage development with respect to both investigator-initiated trials.

Revenues

Product revenues for the three months ended June 30, 2026 were $1,493,788, as we began commercial distribution of LYMPHIR in December 2025. Gross profit on product revenues for the three months ended June 30, 2026 was approximately 67%.

We believe that revenues will increase in the future as LYMPHIR gains market acceptance and have already seen initial accounts placing repeat orders, and on April 29, 2026, we announced our initial shipment to Europe.

Research and Development Expenses

For the three months ended June 30, 2026, research and development expenses were $218,496, as compared to $938,277 for the three months ended June 30, 2025. The decrease of $719,781 was primarily related to lower regulatory expenses recognized in the three months ended June 30, 2026, related to a refund of FDA PDUFA fees as well as a lower allocation of internal expense as both investigator-initiated trials have been completed.

Amortization of in-process research and development

Amortization of in-process research and development commenced upon revenue generation in December 2025. For the three months ended June 30, 2026, amortization was $1,720,312. In-process research and development is being amortized on a straight-line basis over the remaining FDA product exclusivity period, which ends in August 2036.

General and Administrative Expenses

For the three months ended June 30, 2026, general and administrative expenses were $4,219,163, as compared to $1,881,447 for the three months ended June 30, 2025. The increase of $2,337,716 was primarily related to the expansion of our commercial organization to support the continued launch effort of LYMPHIR.

Stock-based Compensation Expense

For the three months ended June 30, 2026, stock-based compensation expense was $3,560,791, as compared to $2,125,237 for the three months ended June 30, 2025. The increase of $1,435,554 in stock-based compensation expense was primarily related to the restricted stock units granted in September 2025.

Interest Income

For the three months ended June 30, 2026, interest income was $96,848, as compared to $0 for the three months ended June 30, 2025. We have invested some of the proceeds of our recent equity offerings in a money market account.

Interest Expense

For the three months ended June 30, 2026, interest expense was $231,732, as compared to $160,755 for the three months ended June 30, 2025, primarily related to our new loan agreement.

Income Taxes

The Company recorded a deferred income tax benefit of $107,347 in the three months ended June 30, 2026 and a deferred income tax expense of $264,240 in the three months ended June 30, 2025. Deferred income tax expense or benefit is related to the difference in amortization for taxable purposes of our in-process research and development asset and the financial statement amortization.

Net Loss

For the three months ended June 30, 2026, we incurred a net loss of $8,923,846, as compared to a net loss of $5,369,956 for the three months ended June 30, 2025. The increase of $3,553,890 in the net loss was primarily due to the increase of $4,773,801 in operating expenses offset by the increase in gross profit of $1,001,945.

Revenues

Product revenues for the nine months ended June 30, 2026 were $7,105,197, as we began commercial distribution of LYMPHIR in December 2025. Gross profit on product revenues for the nine months ended June 30, 2026 was approximately 77%.

Research and Development Expenses

For the nine months ended June 30, 2026, research and development expenses were $2,316,202, as compared to $5,342,198 for the nine months ended June 30, 2025. The decrease of $3,025,996 was primarily related to additional expense recognized in the nine months ended June 30, 2025 for a pre-license inspection batch of LYMPHIR and lower regulatory expenses for the refund of FDA PDUFA fees recognized in the nine months ended June 30, 2026, as well as lower internal allocation of expense as both investigator-initiated trials have been completed.

Amortization of in-process research and development

Amortization of in-process research and development commenced upon revenue generation in December 2025. For the nine months ended June 30, 2026, amortization was $4,014,062. In-process research and development is being amortized on a straight-line basis over the remaining FDA product exclusivity period, which ends in August 2036.

General and Administrative Expenses

For the nine months ended June 30, 2026, general and administrative expenses were $30,704,141, as compared to $7,446,753 for the nine months ended June 30, 2025. The increase of $23,257,388 was primarily related to a notice of termination from a contract manufacturing organization received in February 2026. In March 2026, we recorded a contract cancellation fee of $19,733,307.

Stock-based Compensation Expense

For the nine months ended June 30, 2026, stock-based compensation expense was $11,043,551, as compared to $6,022,287 for the nine months ended June 30, 2025. The increase of $5,021,264 in stock-based compensation expense was primarily related to the restricted stock units granted in September 2025.

Interest Income

For the nine months ended June 30, 2026, interest income was $168,857, as compared to $0 for the nine months ended June 30, 2025. We have invested some of the proceeds of our recent equity offerings in a money market account.

Interest Expense

For the nine months ended June 30, 2026, interest expense was $310,604, as compared to $160,755 for the nine months ended June 30, 2025, primarily related to our new loan agreement.

Income Taxes

The Company recorded a deferred income tax benefit of $74,317 for the nine months ended June 30, 2026 and a deferred income tax expense of $792,720 for the nine months ended June 30, 2025. Deferred income tax expense or benefit is related to the difference in amortization for taxable purposes of our in-process research and development asset and the financial statement amortization.

Net Loss

For the nine months ended June 30, 2026, we incurred a net loss of $41,067,610, as compared to a net loss of $19,764,713 for the nine months ended June 30, 2025. The increase of $21,302,897 in net loss was due to the increase of $29,266,718 in operating expenses offset by the increase in gross profit of $5,495,268, the increase in other income of $1,601,516 and the decrease in income tax expense of $867,037.

LIQUIDITY AND CAPITAL RESOURCES

Liquidity and Working Capital

Citius Oncology has incurred operating losses since inception and incurred a net loss of $41,067,610 for the nine months ended June 30, 2026. At June 30, 2026, we had an accumulated deficit of $105.1 million. The Company has had limited revenue commencing in December 2025 and had historically relied on funding from Citius Pharma to finance our operations. At June 30, 2026, we had $16.6 million in cash and a negative working capital of approximately $16.1 million.

On May 5, 2026, Citius Oncology received net proceeds of approximately $9.7 million from the exercise of certain warrants.

On May 5, 2026 the Company, entered into a term loan agreement with two lenders (the “Lenders”) for up to $25.0 million (the “Loan Agreement”), with $10.0 million funded on May 6, 2026, up to $7.0 million available between October 1 and December 31, 2026, if certain net revenue and liquidity milestones are achieved (“Tranche 2”), and up to $8.0 million available between January 1 and March 31, 2027, if certain additional net revenue milestones are achieved and a loan was drawn between October 1 and December 31, 2026 (“Tranche 3”). The loans bear interest at the greater of the prime rate plus 6% or 12.75%. The loans are secured by all of the Company’s assets, subject to agreed exceptions. The maturity date of the loans is November 1, 2029.

In order to satisfy our outstanding milestone payment obligations, as well as meet minimum purchase commitments under our agreements for the manufacture and supply of our drug product, in addition to generating income from the sale of LYMPHIR, we need to obtain substantial additional financing and cannot be sure that any additional funding will be available on terms favorable to us, or at all. As of June 30, 2026, our outstanding milestone payments and purchase commitments include:

●

On March 28, 2025, we entered into a letter agreement to pay Eisai $2,535,318 on or before July 15, 2025, and $2,350,000 thereafter on the 15^th of each of the next four months, and make a final payment of $2,197,892 on or before December 15, 2025, in each case with interest on each obligation from its original due date at the rate of 2% per annum. As of June 30, 2026, we have paid the milestone in full and owe a balance of approximately $6.3 million to Eisai for certain other invoices.

●

At the time of the FDA approval for LYMPHIR, a $27.5 million milestone payment became payable to Dr. Reddy’s of which a balance of $15.65 million remains due as of June 30, 2026. Dr. Reddy’s has agreed to a partial deferral without penalty of this milestone payment.

●

The Company had previously entered into an agreement with a contract manufacturing organization, (“CMO”) for the manufacture and supply of bulk drug substance, (“BDS”) with the agreement continuing through calendar year 2026. The agreement was terminated effective February 2026 by the CMO due to the breach of payment obligations by the Company. Termination fees associated with this are approximately $20.1 million consisting of $17.1 million of charges associated with manufacturing which was previously committed in 2025 and 2026 but not produced, as well as $1.2 million of un-invoiced but incurred charges related to previous manufactured batches and $1.8 million of interest and other charges. These fees are included in General and Administrative Expense for nine months ended June 30, 2026. Separately, in March 2026 the CMO gave notice that it made a decision to terminate all production at the current site related to microbial manufacturing and decommission the associated manufacturing lines. In March 2026 and in connection with the notice of termination from the CMO, we recorded a contract cancellation fee of $19,733,307 net of invoices already included in accounts payable.

In June 2026, the Company entered into a letter of intent with a new CMO for the purpose of supplying BDS and expects to enter into a master services agreement. At this time, we anticipate no interruption in commercial supply for the foreseeable future.

●

As of June 30, 2026, the Company also has commercial supply agreements with two other vendors for the completion and packaging of finished drug products. Minimum purchase commitments under these two agreements are approximately $4.0 million consisting of purchase commitment obligations of $2.2 million in calendar years 2026 and $1.8 million in 2027.

We plan to continue to partially rely on funding from Citius Pharma, to raise capital through equity and debt financings, and to generate revenue from sales of LYMPHIR. We also have retained Jefferies LLC as our exclusive financial advisor in evaluating strategic alternatives aimed at maximizing shareholder value. There is no assurance, however, that Citius Pharma will have the resources to continue partially funding us, that we will be successful in raising the needed capital and, if funding is available, that it will be available on terms acceptable to us or that we will find strategic partners or generate substantial revenue from the sale of LYMPHIR.

After giving effect to our May 2026 equity and debt financings, we expect that we and Citius Pharma collectively will have sufficient funds to continue our operations through November 2026. We will need to raise additional capital in the future to support our operations beyond November 2026. There is no assurance, however, that we will be successful in raising needed capital or that the proceeds will be received in an amount or in a timely manner to support our operations.

Investing Activities

During the nine months ended June 30, 2026, we paid the final $2,900,000 due to Eisai in connection with the LYMPHIR approval milestone and paid $4,100,000 in connection with the milestone payment due to Dr. Reddy’s. At June 30, 2026, we owe Dr. Reddy’s $15,650,000 representing the balance of the approval milestone.

Inflation

Our management believes that inflation has not had a material effect on our results of operations.

Off Balance Sheet Arrangements

We do not have any off-balance sheet arrangements.

Critical Accounting Policies and Estimates

The preparation of our financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and the disclosure of contingent assets and liabilities as of the date of the financial statements and the amounts of revenues and expenses recorded during the reporting periods. We base our estimates on historical experience, where applicable, and other assumptions that we believe are reasonable under the circumstances. Actual results may differ from our estimates under different assumptions or conditions.

Our critical accounting policies and use of estimates as discussed in the footnotes to the condensed consolidated financial statements included within this Form 10-Q should also be read in conjunction with, the annual consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended September 30, 2025, filed with the SEC on December 23, 2025.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Not applicable.

Item 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures designed to provide reasonable assurance that information required to be disclosed in reports filed under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), is recorded, processed, summarized and reported within the specified time periods and accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding disclosure.

Our Chief Executive Officer (who is our principal executive officer) and Chief Financial Officer (who is our principal financial officer and principal accounting officer), evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) promulgated under the Exchange Act) as of June 30, 2026. In designing and evaluating disclosure controls and procedures, we recognize that any disclosure controls and procedures, no matter how well designed and operated, can only provide reasonable assurance of achieving the desired control objective. As of June 30, 2026, based on the evaluation of these disclosure controls and procedures, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective in ensuring that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms.

Changes In Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting during the quarter ended June 30, 2026 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II - OTHER INFORMATION

Item 1. Legal Proceedings.

None.

Item 1A. Risk Factors.

There have been no material changes to the Company’s risk factors as disclosed in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2025, filed with the SEC on December 23, 2025, except as set forth below.

Our substantial indebtedness and debt service obligations could adversely affect our financial condition and our ability to fulfill our obligations under the Loan Agreement.

We have incurred significant indebtedness under the Loan Agreement, which features a tiered tranche structure with a floating interest rate subject to a floor of 12.75% per annum. During the interest-only period, we will not reduce the outstanding principal balance of the loan, and upon expiration of such period, we will be required to make amortizing payments of principal and interest. In addition, we are obligated to make a final payment of $1,062,500 at maturity, which creates a balloon-type obligation that we may be unable to satisfy from available cash flows or other sources. There can be no assurance that our business will generate sufficient cash flow from operations or that future borrowings or other sources of capital will be available to us in an amount sufficient to enable us to pay our indebtedness or to fund our other liquidity needs. If we are unable to generate sufficient cash flow to service our debt and meet our other obligations, we may need to refinance or restructure our debt, sell assets, reduce or delay capital expenditures, or seek additional equity capital, any of which could have a material adverse effect on our business, financial condition, and results of operations.

Additional funding tranches under the Loan Agreement are conditioned upon the achievement of specified milestones, and there can be no assurance that such milestones will be achieved.

The availability of Tranche 2 and Tranche 3 under the Loan Agreement is conditioned upon our achievement of specified net revenue and liquidity milestones. If we fail to achieve the required milestones within the applicable time periods, Tranche 2 and/or Tranche 3 will not become available to us, and we will not have access to the additional committed capital contemplated by the Loan Agreement.

Our failure to access these additional tranches could significantly impair our ability to fund ongoing operations, pursue growth initiatives, or meet our working capital requirements. In such event, we may be required to seek alternative sources of financing, which may not be available on terms acceptable to us, or at all, or we may be required to curtail our operations or delay or abandon planned expenditures. Any of these outcomes could have a material adverse effect on our business, financial condition, results of operations, and prospects.

The Loan Agreement is secured by a lien on substantially all of our assets, including our intellectual property, and the Lenders could foreclose on such assets upon an event of default.

Our obligations under the Loan Agreement are secured by a first-priority lien on substantially all of our assets, including our intellectual property, accounts receivable, inventory, equipment, and general intangibles. If an event of default occurs and is not cured within any applicable cure period, the Lenders would have the right to foreclose on the collateral securing our obligations.

The foreclosure on, or loss of, substantially all of our assets, including our intellectual property, could result in a complete loss of our ability to operate our business and would likely render us unable to continue as a going concern. Our intellectual property, including patents, trademarks, trade secrets, and proprietary technology, constitutes a critical component of our competitive position and revenue-generating capabilities. The loss of such assets to the Lenders in a foreclosure action would have a material adverse effect on our business and could result in a total loss of stockholder value.

The conversion of loan principal into shares of our common stock and the exercise of Lender Warrants could result in significant dilution to our existing stockholders and may adversely affect the market price of our common stock.

Under the terms of the Loan Agreement, the Lenders have the right to convert up to $4.0 million of outstanding principal into shares of our common stock at a $1.08 per share conversion price. In addition, we have issued warrants to the Lenders equal to 10% of the portion of the loans actually funded that are exercisable at $0.90 per share. The conversion of loan principal and/or the exercise of these warrants would result in the issuance of additional shares of our common stock and would dilute the ownership interest of our existing stockholders. Such anticipated dilution could depress the market price of our common stock, even before any actual conversion or exercise occurs. Furthermore, the Lenders may sell any shares acquired upon conversion or exercise into the market, which could create downward pressure on our stock price. Any or all of these factors could materially adversely affect the market price of our common stock and the value of an investment in our securities.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

In connection with our warrant inducement offering which closed on May 6, 2026, we issued to a financial advisor warrants to purchase up to 511,111 shares of our common stock with an exercise price of $1.199 per shares and have a five-year term. The warrants were issued in a private placement pursuant to Section 4(a)(2) of the Securities Act of 1933, as amended.

Item 3. Defaults Upon Senior Securities.

None.

Item 4. Mine Safety Disclosures.

Not applicable.

Item 5. Other Information.

During the quarter ended June 30, 2026, none of our directors or officers adopted, modified, or terminated a Rule 10b5-1 trading arrangement or a non-Rule 10b5-1 trading arrangement for the purchase or sale of our securities.
