First Quarter and Recent Highlights

● In January 2026, we launched YARTEMLEA in the U.S. market. During the quarter, gross product sales were $11.1 million and associated net sales, after deduction of wholesaler distribution fees and chargebacks, were $9.9 million.

● Net income for the first quarter of 2026 was $56.1 million, or $0.78 per share, compared to a net loss of $33.5 million, or $0.58 per share, for the first quarter of 2025.

● First quarter results include a $73.1 million non-cash gain associated with the mark-to-market adjustment on the embedded derivatives related to our 2029 unsecured convertible notes (the "2029 Notes"). Excluding the non-cash change in our embedded derivatives, non-GAAP adjusted net loss for the three months ended March 31, 2026 was $17.1 million, or $0.24 per share.

● At March 31, 2026, we had $135.3 million of cash and short-term investments. This balance includes the February 2026 repayment at maturity of the remaining $17.1 million aggregate principal amount of our 2026 unsecured convertible notes (the "2026 Notes"). Following that repayment, our only remaining debt outstanding is $70.8 million aggregate principal amount of our 2029 Notes, which mature in June 2029.

● In April, the U.S. Centers for Medicare & Medicaid Services ("CMS") assigned a permanent Healthcare Common Procedure Coding System J-code specific for YARTEMLEA. This simplifies billing and reimbursement across payors. The J-code becomes effective on July 1, 2026. Also in April, CMS, in its Inpatient Prospective Payment System proposed rule, recommended approval of the New Technology Add-On Payment ("NTAP") for YARTEMLEA. NTAP provides additional payments to hospitals for certain high-cost, innovative technologies, helping bridge the gap until standard payment systems incorporate them. The final rule is expected in August, with NTAP expected to be effective October 1, 2026.

"The launch of YARTEMLEA has changed the trajectory of Omeros, both operationally and financially," said Gregory A. Demopulos, M.D., Omeros’ Chairman and Chief Executive Officer. "We are seeing strong early adoption across transplant centers, expanding formulary access, favorable reimbursement support, and growing physician experience with the first and only approved treatment for TA-TMA. At the same time, our Novo Nordisk transaction has strengthened our balance sheet and accelerated advancement of our pipeline, including next-generation MASP-2 programs, OncotoX-AML, OMS527 for cocaine use disorder under NIDA funding, and our T-CAT platform targeting multidrug-resistant pathogens. The progress achieved this quarter further demonstrates the strength of our science and the value we are creating across Omeros."

Recent Developments

● YARTEMLEA and our other MASP-2 inhibitor programs

o A marketing authorization application ("MAA") for YARTEMLEA for the treatment of TA-TMA is currently under review by the European Medicines Agency ("EMA") with a decision expected in mid-2026. If approved, the MAA authorizes the product to be marketed in all EU member states and European Economic Area countries.

o We are assessing opportunities for YARTEMLEA across indications involving lectin pathway activation, including acute respiratory distress syndrome (ARDS), sickle cell disease, acute kidney injury, solid organ transplant-related TMA, and delayed graft function.

o In parallel, we are finalizing selection of an indication for a Phase 2 clinical program for OMS1029, our long-acting antibody targeting MASP-2. In our MASP-2 small-molecule inhibitor program, we have selected a drug development candidate and are advancing to IND-enabling studies.

● OMS527 for the treatment of addiction — cocaine use disorder program funded by the National Institute on Drug Abuse ("NIDA")

o We are developing, at NIDA’s request, our lead orally administered phosphodiesterase 7 ("PDE7") inhibitor for the treatment of cocaine use disorder. Preclinical studies, designed with NIDA toxicologists, were completed and showed no drug-interaction or safety issues, supporting the scheduled in-patient human study of OMS527 in cocaine users.

o Following FDA’s request for additional nonclinical information and a subsequent meeting with FDA to discuss that request, we are working with FDA to streamline the path to initiate the in-patient clinical trial, targeted for initiation by year-end 2026.

● Oncology platform — OncotoX-AML

o We continue to progress preclinical studies within our novel oncology program. The lead indication for development is acute myeloid leukemia ("AML"), an aggressive and highly fatal bone marrow and blood cancer. We have completed selection of a drug development candidate in the OncotoX-AML program, and IND-enabling studies are underway.

o OncotoX-AML shows broad application across AML regardless of genetic mutation, including TP53, NPM1, KMT2A, and FLT3, collectively found in approximately 90% of AML patients. In human tumor-bearing animal and in vitro human AML cell-line studies, our AML therapeutic candidate has demonstrated superior efficacy to current AML standard of care treatments.

o In February 2026, we announced the successful completion of our initial study in nonhuman primates evaluating the efficacy and safety of OncotoX-AML. Administration of only one course of OncotoX-AML treatment to immunocompetent primates demonstrated the desired pharmacologic response, selectively reducing myeloid progenitor cells, which can mutate and lead to AML, by up to 99%. OncotoX-AML was well tolerated. There were no observed safety signals or meaningful changes in blood chemistry values.

● Targeted Complement Activating Therapy ("T-CAT") platform

o Our T-CAT platform is a new class of recombinant antibodies designed to target and directly kill pathogens, including bacteria, fungi, viruses, and parasites. Our initial focus is on multidrug-resistant organisms ("MDROs"), one of the most critical unmet needs in medicine.

o Data from our T-CAT platform were recently featured in a podium presentation at the annual congress of the European Society of Clinical Microbiology and Infectious Diseases.

o The seminal manuscript describing our T-CAT technology was accepted for publication in Science Translational Medicine.

Financial Results

Commercial distribution and sales of YARTEMLEA commenced in January 2026. Gross product sales for the three months ended March 31, 2026 were $11.1 million, with net sales of $9.9 million. Revenue for the period reflects sales of YARTEMLEA to U.S. wholesalers.

Net income for the first quarter of 2026 was $56.1 million, or $0.78 per share, compared to a net loss of $33.5 million, or $0.58 per share for the first quarter of 2025.

The change in fair value of financial instruments as shown in our statement of operations and comprehensive income (loss) reflects marking to market the embedded derivative on our 2029 Notes under GAAP. Excluding the net gain on the change in the fair value of our financial instruments, which is non-cash, our non-GAAP adjusted net loss for the three months ended March 31, 2026 was $17.1 million, or $0.24 per share.

At March 31, 2026, we had $135.3 million of cash and short-term investments. Upon their maturity in February 2026, we repaid the remaining $17.1 million outstanding principal balance of our 2026 Notes and currently have only $70.8 million aggregate principal amount outstanding of our 2029 Notes, which mature in June 2029.

Total operating expenses for the three months ended March 31, 2026 were $27.3 million compared to $35.0 million for the three months ended March 31, 2025. The $7.7 million decrease was primarily due to reduced OMS906-related research and development work as a result of the zaltenibart asset sale and licensing agreement with Novo Nordisk in November 2025.

Interest expense increased $2.2 million for the three months ended March 31, 2026 compared to the three months ended March 31, 2025. The increase primarily relates to interest incurred on the 2029 Notes and, to a lesser extent, a non-cash remeasurement charge taken on our OMIDRIA royalty obligation in the prior year, offset by decreased interest incurred on our 2026 Notes, which were repaid in February 2026.

Interest and other income was $1.5 million for the three months ended March 31, 2026 compared to $1.1 million for the three months ended March 31, 2025 due to holding higher cash and investment balances in the current period.

Net income from discontinued operations, net of tax, was $4.8 million, or $0.07 per share, for the three months ended March 31, 2026 compared to $4.1 million, or $0.07 per share, in the prior year period.

During the three months ended March 31, 2026, we repurchased and retired approximately 0.4 million shares of common stock pursuant to our share repurchase program, at an average cost of $11.70 per share, for an aggregate purchase price of $4.2 million.

On May 13, 2026 Moleculin Biotech, Inc., (Nasdaq: MBRX) ("Moleculin" or the "Company"), reported that it is approaching the first unblinding of data from its pivotal Phase 2B/3 "MIRACLE" trial evaluating Annamycin in combination with cytarabine for the treatment of subjects that have been relapsed or refractory to their primary line of treatment for acute myeloid leukemia (R/R AML). The trial incorporates two arms of Annamycin at different doses plus cytarabine compared to the control arm of cytarabine plus a placebo. The Company continues to expect this unblinding to occur prior to June 30, 2026, as previously communicated.

The Company also reported that preliminary blinded efficacy data for the 45 subjects continue to approximate previously disclosed results, including a composite complete remission rate (CRc) exceeding 40% and a complete remission (CR) rate of approximately 30%. These results compare favorably to historical CR rates from two major trials of approximately 17-18% observed with cytarabine alone in similar patient populations. Cytarabine is a currently approved standard of care for second line treatment of AML. Based on preliminary data, the median age for subjects enrolled is in the mid-60’s, with over 30% entering the trial after becoming relapsed from or refractory (R/R) to a prior venetoclax regimen as first line therapy, which is considered a particularly challenging patient group. As of May 1st, a total of 56 subjects have been recruited in the MIRACLE trial to date keeping the Company on track to recruit the 90th subject in Part A in Q3 2026.

"The data coming from MIRACLE is encouraging" said Walter Klemp, Chairman and CEO of Moleculin. "For decades, cytarabine monotherapy regimens, although one of the current standards of care, have set a relatively low bar in relapsed or refractory AML, with historical complete remission rates hovering around 17-18% in previously referenced clinical trials. With our trial comparing two arms of Annamycin in combination with cytarabine compared to cytarabine with a placebo, we are looking forward to the opportunity of showing Annamycin is additive to cytarabine alone in a head to head trial. Against this backdrop, the data emerging from MIRACLE highlight what could be a substantial advancement, suggesting that we may finally be moving beyond the limitations that have defined standard-of-care outcomes."

MIRACLE Trial Progress and Next Steps

The MIRACLE study (derived from Moleculin R/R AML AnnAraC Clinical Evaluation) is a Phase 2B/3, global multi-center, randomized, double-blind, placebo-controlled, adaptive designed clinical trial whereby data from the 2B (Part A) portion will be combined with the Phase 3 (Part B) portion for purposes of measuring its primary efficacy endpoint. Part A of the MIRACLE trial is designed to evaluate the effectiveness of Annamycin in two dosing arms (190 mg/m² and 230 mg/m²) in combination with cytarabine (also referred to as Ara-C) as compared to a control arm of cytarabine plus placebo. The protocol for the MIRACLE trial allows for the unblinding of preliminary primary efficacy data of the three arms at 45 subjects in Part A, in addition to the conclusion of Part A (at 90 total subjects). The first early unblinding should yield approximately 30 subjects treated with Annamycin (190 mg/m2 and 230 mg/m2) in combination with cytarabine and 15 subjects treated with just cytarabine plus placebo. The MIRACLE trial is being offered only to AML patients who have had a single prior induction therapy (2nd line patients or 2L) including subjects that were treated with a Venetoclax regimen.

The unblinding of the first 45 subjects is on track to occur in late Q2 2026, as the data are subject to final data entry and audit. The second group of 45 subjects in Part A are expected to be fully recruited in the third quarter of 2026 with unblinding expected late in the second half of 2026. Recruitment of the second group of 45 subjects in Part A will continue uninterrupted while the first 45 subjects with efficacy are being unblinded. Unblinding for the full 90 subjects in Part A may require more time than for the first 45 as it involves more data to support the transition from Part A to Part B.

For more information about the MIRACLE trial, visit clinicaltrials.gov and reference identifier NCT06788756. Additionally, the clinical trial in the EU can be found on euclinicaltrials.eu and the reference identifier is 2024-518359-47-00.

Annamycin, also known by its non-proprietary name of naxtarubicin, currently has Fast Track Status and Orphan Drug Designation from the FDA for the treatment of relapsed or refractory acute myeloid leukemia, in addition to Orphan Drug Designation for the treatment of soft tissue sarcoma. Annamycin also benefits from composition of matter patent protection through 2040 with the potential to extend that protection as far as 2045. Furthermore, Annamycin has Orphan Drug Designation for the treatment of relapsed or refractory acute myeloid leukemia from the EMA.

"We are very pleased to report a strong start to the year, building on the momentum generated in 2025. These results reflect our team’s disciplined execution of a strategy designed to sharpen our focus, maximize the value of our pipeline, and strengthen our financial position. As part of this effort, we recently announced the sale of our GMP manufacturing operations to Bora Pharmaceuticals and the monetization of additional ZYNYZ royalties with Sagard Healthcare Partners. Subject to the closing of the manufacturing operations divestiture, these transactions are expected to provide significant non-dilutive capital to support growth opportunities in 2026 and beyond," said Eric Risser, President and CEO of MacroGenics. "We look forward to providing multiple updates during the remainder of the year, including key programmatic milestones for MGC026, MGC028, and MGC030. We believe our increased focus on discovering and developing breakthrough medicines has the potential to enhance patients’ lives while creating meaningful value for our shareholders."

Focus and Realignment Across Our Business

MacroGenics recently took a series of significant steps designed to focus resources on the Company’s innovative oncology programs. These steps include:

Divestiture of Manufacturing Operations. As announced earlier this week, MacroGenics entered into a definitive agreement with Bora Pharmaceuticals Co., Ltd. and Bora Biologics USA, LLC (collectively, Bora) to sell its manufacturing operations, inclusive of drug substance manufacturing, development and quality services. Subject to customary closing conditions, MacroGenics is expected to receive an upfront payment of $122.5 million, before transaction fees and expenses. As part of this transaction, MacroGenics’ headquarters and warehouse sites in Maryland will transfer to Bora. The transaction is expected to close in the third quarter of this year. At closing, MacroGenics will enter into a supply agreement with Bora to support development and production of clinical drug substance for current and future pipeline programs. The Company has historically leveraged both internal manufacturing capabilities as well as those of external contract manufacturing partners. Through this transaction, the Company will transition to a fully outsourced model, which is expected to provide increased flexibility and cost advantages.

Expanded ZYNYZ Royalty Monetization. Earlier this month, MacroGenics announced that it had entered into an amended royalty purchase agreement with Sagard Healthcare Partners (Sagard) in exchange for a revised capped royalty interest in future global net sales of ZYNYZ. MacroGenics received a $60.0 million cash payment from Sagard with the potential to receive an additional milestone, based on 2026 ZYNYZ sales performance, of up to $20.0 million.

Corporate Restructuring. As part of the manufacturing divestiture transaction, approximately 140 employees are expected to transfer to Bora. With some additional reductions across the company, MacroGenics is expected to have approximately 135 employees at closing, enabling a more agile organization that is focused on the research and clinical development of novel therapeutics.

Advancement of Innovative Pipeline

MacroGenics is developing potential best-in-class or first-in-class antibody-drug conjugates (ADCs) and T-cell engagers (TCEs). MacroGenics’ two clinical-stage ADC programs, MGC026 and MGC028, continue to demonstrate acceptable safety profiles to date, with no observations of interstitial lung disease, as well as evidence of anti-tumor activity by Response Evaluation Criteria in Solid Tumors (RECIST).

MGC026 is a novel ADC that targets B7-H3, which is overexpressed in multiple solid tumors. The Company completed enrollment of the dose escalation portion of a Phase 1 study in late 2025 and is currently enrolling patients in the dose expansion portion of the study in selected solid tumor indications. The Company anticipates reporting initial MGC026 clinical data in mid-2026.

MGC028 is a first-in-class ADC that targets ADAM9, which is overexpressed in multiple solid tumors. MGC028 is currently being evaluated in the dose escalation portion of a Phase 1 study in patients with advanced solid tumors. The Company anticipates reporting initial MGC028 clinical data in the second half of 2026.

MGC030 is a first-in-class preclinical ADC that targets an undisclosed antigen expressed across several solid tumors. An Investigational New Drug (IND) application to the U.S. Food and Drug Administration (FDA) for MGC030 is planned for the third quarter of 2026.

Future Pipeline. MacroGenics is advancing additional preclinical programs that incorporate proprietary platforms for next-generation TCEs and ADCs with novel payloads. The company expects to nominate two additional product candidates by the end of 2026.

Lorigerlimab Update

MacroGenics continues its LINNET Phase 2 monotherapy study of lorigerlimab, a PD-1 × CTLA-4 bispecific DART molecule, in patients with gynecological cancers.

As of a data cut-off on May 7, 2026, 17 patients with clear cell gynecologic cancer (CCGC) were treated at 6 mg/kg every three weeks (Q3W). Of the 16 evaluable patients with CCGC, 4 (25%) had objective responses, including 4 with confirmed partial responses (PR), of which 1 patient subsequently had an unconfirmed complete response (CR). Of the 17 CCGC patients evaluable for safety, Grade ≥3 treatment-related adverse events (TRAEs) occurred in 8 patients (47%) and 2 patients (12%) discontinued treatment due to AEs. No treatment-related fatalities were reported in these patients.

Going forward, MacroGenics intends to enroll an additional 20 CCGC patients at a lower dose of 3 mg/kg Q3W, which was selected based on pharmacokinetic and pharmacodynamic modeling, with the goal of improving safety while maintaining clinical benefit. The Company anticipates completing enrollment of these 20 patients by year-end 2026 and reporting updated study results in the first half of 2027.

Based on an assessment of results from the high-grade serous and platinum-resistant ovarian cancer (PROC) cohort of the LINNET study, the predetermined response rate was not achieved, and the Company no longer intends to pursue development in this indication.

Current Partnerships

MacroGenics maintains partnerships with Incyte Corporation, Sanofi, and Gilead Sciences, which span multiple commercial, clinical and preclinical programs. These include ZYNYZ (retifanlimab-dlwr), TZIELD (teplizumab-mzwv), and MGD024, a clinical-stage CD123 × CD3 bispecific DART molecule. Across these collaborations, the Company remains eligible to receive up to approximately $2.5 billion in aggregate future milestones, in addition to royalties on partnered products.

First Quarter 2026 Financial Results

Cash Position: Cash, cash equivalents and marketable securities balance as of March 31, 2026, was $154.2 million, compared to $189.9 million as of December 31, 2025. The balance as of March 31, 2026, did not include the $60.0 million received from Sagard earlier this month. In addition, the Company is expected to receive $122.5 million proceeds from Bora, less related transaction fees and expenses, in connection with the manufacturing operations divestiture, which is expected to close in the third quarter of this year, subject to customary closing conditions.

Revenue: Total revenue was $20.8 million for the quarter ended March 31, 2026, compared to $13.2 million for the quarter ended March 31, 2025. The increase was due to higher contract manufacturing revenue from higher production volume for external clients and royalty revenue recognized from higher sales of ZYNYZ, offset by decreased collaborative revenue.

Cost of Manufacturing Services: Cost of manufacturing services was $9.5 million for the quarter ended March 31, 2026, compared to $5.4 million for the quarter ended March 31, 2025. The increase was due to increased production for external clients.

R&D Expenses: Research and development expenses were $35.0 million for the quarter ended March 31, 2026, compared to $39.7 million for the quarter ended March 31, 2025. The decrease is primarily due to the discontinuation of further development of vobramitamab duocarmazine. This was partially offset by increased development costs related to MGC028 and the preclinical TCE programs.

G&A Expenses: General and administrative expenses were $9.7 million for the quarter ended March 31, 2026, compared to $10.7 million for the quarter ended March 31, 2025.

Net Loss: Net loss was $36.8 million for the quarter ended March 31, 2026, compared to $41.0 million for the quarter ended March 31, 2025.
Shares Outstanding: Shares of common stock outstanding as of March 31, 2026, were 63,560,068.
Cash Runway Guidance: MacroGenics anticipates that its cash, cash equivalents and marketable securities balance of $154.2 million as of March 31, 2026, in addition to projected and anticipated future payments from partners, including $60.0 million received from Sagard earlier this month plus anticipated sale proceeds of $122.5 million, less related transaction fees and expenses, from Bora related to divestiture of the Company’s manufacturing operations, is expected to support its cash runway through 2028.

"We remain focused on advancing INO-3107 toward its target PDUFA date to ensure that every RRP patient has access to therapeutic options that work for them to reduce the need for surgery. We believe there remains a critical unmet need among patients diagnosed with this rare and devastating disease, and that INO-3107 has the potential to become the preferred product by patients and their physicians, if approved, based on clinical results, tolerability data and the simplicity of its patient-centric treatment regimen that does not require additional surgeries during the dosing window," said Dr. Jacqueline Shea, INOVIO’s President and Chief Executive Officer. "While the BLA for INO-3107 is under active review, we continue to advance our commercial readiness plans in anticipation of a 2026 approval, as well as leverage the power of partnerships to advance other promising candidates in our pipeline."

Operational Highlights

INO-3107 – Recurrent Respiratory Papillomatosis (RRP)
INO-3107 is INOVIO’s lead product candidate. It has been developed as a potential treatment for RRP, a rare and debilitating disease of the respiratory tract caused by infection with HPV-6 and/or HPV-11. In December 2025, the FDA accepted for review the company’s BLA for INO-3107 under the accelerated approval program and set a target PDUFA date for October 30, 2026. Since then, the BLA has been under active review by the FDA, including the recent completion of the mid-cycle review meeting. INOVIO is focused on advancing INO-3107 through the regulatory process and working with the FDA as they complete their review of the BLA, including addressing the potential review issue they noted in their file acceptance letter regarding eligibility for review under the accelerated approval program. INOVIO continues to strongly believe that INO-3107 fulfills the criteria for accelerated approval by meeting a significant unmet need and providing a meaningful therapeutic benefit over existing treatments. As a part of communications about the mid-cycle review, the FDA has reiterated their intention to schedule the previously agreed to informal meeting to discuss their preliminary commentary on eligibility for review under the accelerated approval program.

INOVIO continues to engage with the RRP community, including presenting data from our Phase 1/2 trial of INO-3107 at the Combined Otolaryngology Spring Meeting (COSM), the premier educational and technology forum for the specialists who treat RRP. INOVIO will also be presenting at the upcoming American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Conference.

In anticipation of a potential approval in 2026, INOVIO continues to advance commercial readiness plans, including incorporating key learnings from the launch of a competitor’s recently approved RRP product. INOVIO believes INO-3107 has a positively differentiated product profile. INOVIO plans to commercialize INO-3107 itself in the U.S., with the support of a contract sales organization, and has engaged or identified key commercial partners, including a third-party logistics provider, Agency of Record, specialty distributor, specialty pharmacy, and patient HUB.

INO-5412
In March 2026, INOVIO announced a clinical trial collaboration and supply agreement with Akeso Inc. to evaluate INO-5412 (INO-5401 plus INO-9012 in a single vial) in combination with cadonilimab, Akeso’s first-in-class PD-1/CTLA-4 bispecific antibody, for the potential treatment of glioblastoma (GBM). The combination therapy will be studied as a part of the INdividualized Screening trial of Innovative Glioblastoma Therapy (INSIGhT), a Phase 2 adaptive platform trial sponsored by the Dana-Farber Cancer Institute and conducted by Mass General Brigham Cancer Care Inc. This novel combination builds on INOVIO’s previous promising research in GBM and could potentially benefit patients by providing additional checkpoint inhibition through CTLA-4 binding.

Next-Generation DNA Medicine Candidates
INOVIO presented promising data from our next-generation DNA-Encoded Monoclonal Antibody (DMAb) and DNA-Encoded Protein (DPROT) programs at several recent scientific conferences. Based on positive preclinical data on Factor VIII production for Hemophilia A, INOVIO is developing additional DPROT indications in the rare disease space, including Fabry disease and Hypophosphatasia (HPP), and is in discussions with potential partners to accelerate development of this promising platform.

General Corporate
INOVIO remains focused on financial discipline, directing resources to advance the INO-3107 program toward a potential 2026 approval and preparing for commercialization. The company strengthened its balance sheet with an underwritten public equity offering in April 2026. Net proceeds from the offering, after deducting underwriting discounts, commissions and offering expenses, were approximately $16.0 million.

First Quarter 2026 Financial Results

Research and Development (R&D) Expenses: R&D expenses for the three months ended March 31, 2026 decreased to $14.1 million from $16.1 million for the same period in 2025. The decrease was primarily the result of lower employee and consultant compensation, including stock-based compensation, lower engineering outside services related to our device development, and lower expensed inventory, among other variances.
General and Administrative (G&A) Expenses: G&A expenses decreased to $7.9 million for the three months ended March 31, 2026 from $9.0 million for the same period in 2025.
Total Operating Expenses: Total operating expenses decreased to $21.9 million for the three months ended March 31, 2026 from $25.1 million for the same period in 2025.
Net Loss: INOVIO’s net loss for the three months ended March 31, 2026 was $19.7 million, or $0.28 per basic and diluted share, compared to a net loss of $19.7 million, or $0.51 per basic and diluted share, for the three months ended March 31, 2025.
Cash, Cash Equivalents and Short-term Investments: As of March 31, 2026, cash, cash equivalents and short-term investments were $37.7 million (excluding net proceeds from the April 2026 offering of $16.0 million), compared to $58.5 million as of December 31, 2025.
Cash Guidance
INOVIO estimates that current cash, cash equivalents and short-term investments balances will support operations into the first quarter of 2027, beyond the target PDUFA date for INO-3107. This projection includes the net proceeds of $16.0 million from the public offering in April 2026, as well as an operational net cash burn estimate of approximately $18 million for the second quarter of 2026.

"Our TUSCANY clinical trial of tuspetinib in combination with venetoclax (VEN) and azacitidine (AZA) for frontline treatment of newly diagnosed acute myeloid leukemia (AML) continues to deliver robust safety and response data, and we’re pleased that an update of our TUS+VEN+AZA triplet clinical data has been selected for an oral presentation at the upcoming EHA (Free EHA Whitepaper)2026 Congress in June," said William G. Rice, Ph.D., Chairman, President and Chief Executive Officer of Aptose. "Likewise, we are pleased that the expected acquisition of the Company by Hanmi Pharmaceutical will allow the continued development of tuspetinib for AML patients in need of a well-tolerated and broadly active therapy to treat those with even the most adverse of mutation profiles, including those with TP53-mutated disease."

Key Corporate Highlights

Update on Acquisition of Aptose by Hanmi Pharmaceutical – On April 30, 2026, Aptose announced that the closing of the previously announced arrangement (the "Arrangement") with Hanmi Pharmaceutical Co. Ltd. ("Hanmi") and HS North America Ltd., a wholly owned subsidiary of Hanmi (together with Hanmi, the "Hanmi Purchasers"), has been delayed as certain Korean regulatory approvals pertaining to the Arrangement remain under way (press release here). The parties do not anticipate that the regulatory reviews will prevent closing and continue to work toward completing the Arrangement that they target for the month of May. The Company will provide a further update when available.

Under the terms of the Arrangement Agreement, Aptose shareholders, other than the Hanmi Purchasers and their respective affiliates that hold any common shares of Aptose (the "Common Shares"), receive C$2.41 in cash per Common Share, which represents a premium of 28% over Aptose’s 30-day VWAP of C$1.88 on the Toronto Stock Exchange (TSX) at the date of the execution of the Arrangement Agreement.
Aptose Clinical Data to be Presented at EHA (Free EHA Whitepaper) in Oral Presentation – Data from Aptose’s Phase 1/2 TUSCANY trial in newly diagnosed patients treated with tuspetinib (TUS) in combination with standard of care dosing venetoclax and azacitidine (TUS+VEN+AZA triplet) has been selected for oral presentation at the European Hematology Association (EHA) (Free EHA Whitepaper) Congress (EHA 2026), being held June 11-14, 2026, in Stockholm, Sweden. The TUS+VEN+AZA triplet is being developed as a safe and mutation agnostic frontline therapy to treat large, mutationally diverse populations of newly diagnosed AML patients who are ineligible to receive induction chemotherapy. As reported prior, the first two dose cohorts at 40 mg of TUS or 80 mg of TUS in the TUS+VEN+AZA triplet, demonstrated safety, complete remissions, and MRD negativity across patients with diverse mutations, including TP53-mutated/CK AML and FLT3-wildtype AML patients. The oral presentation at EHA (Free EHA Whitepaper) will include updated data at the 80 mg and 120mg dose levels, as well as new data from the 160 mg dose of TUS, updated safety, complete remissions, minimal residual disease (MRD) and other clinical findings with a longer duration of follow up.

RESEARCH AND DEVELOPMENT EXPENSES

Research and development expenses for the three months ended March 31, 2026 and 2025 were as follows:

    Three Months Ended
    March 31,
(in thousands)   2026   2025

Program costs – Tuspetinib $ 2,880 $ 1,479
Program costs – Luxeptinib (5 ) 98
Personnel-related expenses 695 646
Stock-based compensation 51 141
Total $ 3,621 $ 2,364

Research and development expenses increased by $1.2 million to $3.6 million for the three months ended March 31, 2026 as compared to $2.4 million for the comparable period in 2025. Changes to the components of our research and development expenses presented in the table above are primarily as a result of the following activities:

Program costs for tuspetinib increased by $1.4 million to $2.9 million for the three months ended March 31, 2026 compared to $1.5 million for the comparable period in 2025. The higher program costs for tuspetinib in the current period are attributable to increased costs associated with the TUSCANY study as we continue the advancement of tuspetinib.

Program costs for luxeptinib decreased by approximately $0.1 million during the three months ended March 31, 2026 compared to the comparable period in 2025 due to a decrease in clinical trial costs as the trial is being wound down.

Personnel-related expenses remained relatively consistent during the three months ended March 31, 2026 compared to the comparable period in 2025 as headcount for research and development personnel remained consistent between periods.

Stock-based compensation decreased by $0.1 million for the three months ended March 31, 2026 compared to the comparable period in 2025. This decrease was primarily due to stock options forfeited and/or vested in prior periods that are no longer being expensed resulting in lower expense in the current period.
