New major risk - Share price stability The company's share price has been highly volatile over the past 3 months. It is more volatile than 90% of American stocks, typically moving 16% a week. This is considered a major risk. Share price volatility increases the risk of potential losses in the short-term as the stock tends to have larger drops in price more frequently than other stocks. It may also indicate the stock is highly sensitive to market conditions or economic conditions rather than being sensitive to its own business performance, which may also be inconsistent. Currently, the following risks have been identified for the company: Major Risks Less than 1 year of cash runway based on free cash flow trend (-US$16m free cash flow). Share price has been highly volatile over the past 3 months (16% average weekly change). Shareholders have been substantially diluted in the past year (over 29x increase in shares outstanding). Minor Risks Currently unprofitable and not forecast to become profitable over next 3 years (US$6.7m net loss in 3 years). Market cap is less than US$100m (US$48.7m market cap). Announcement • Jan 22

Plus Therapeutics, Inc. Announces Read Out of Type B Meeting with the FDA with Goal of Accelerating Approval of REYOBIQ™? for Leptomeningeal Metastases Plus Therapeutics, Inc. announced the completion of a Type B meeting with the U.S. Food and Drug Administration (FDA) on next steps on REYOBIQ pivotal trial strategy for leptomeningeal metastases (LM). The meeting resulted in constructive discussion with the FDA regarding key elements of the potential pivotal study design for REYOBIQ in LM. Plus intends to incorporate the FDA's feedback in the current dose optimization trial and seek alignment with the FDA on a revised protocol, likely later this year. The company's goal is to be ready for a potential pivotal trial following completion of the current dose optimization trial and, ultimately, work towards the potential approval of REYOBIQ for patients affected by LM. Highlights of FDA responses to the Company's key enquiries: Accelerated approval - FDA indicated that accelerated approval may be appropriate for the LM indication, but there are insufficient data to support the use of circulating tumor cells (CTCs) as an intermediate clinical endpoint. FDA and Plus discussed that additional steps would be necessary to validate CTCs as a surrogate endpoint to potentially support other future applications. Primary and key endpoints - FDA recommended that the study evaluate an endpoint with established clinical benefit, such as overall survival, while encouraging further study of patient reported outcomes and neurological function as endpoints that could potentially support a marketing application. FDA and Plus aligned that CTCs could be considered for use as a secondary endpoint. Trial design and comparator group - FDA and Plus discussed a randomized controlled trial design approach and that the study may include an intrathecal chemotherapeutic as a comparator, as well as approaches to standardize the comparator and any additional interventions available under the trial protocol. Treated populations - FDA conveyed it may be reasonable to incorporate multiple histologies (i.e., multiple underlying disease etiologies) in a single trial. Announcement • Dec 04

Plus Therapeutics, Inc. Announces Initial Patients Successfully Treated in ReSPECT-LM Dose Optimization Trial for REYOBIQ in Leptomeningeal Metastases Plus Therapeutics, Inc. announced the treatment of its initial patients in the Company's ReSPECT-LM dose optimization trial for REYOBIQTM (rhenium Re186 obisbemeda) for the treatment of leptomeningeal metastases (LM). The dose optimization trial builds on promising results from the Company's completed Phase 1 single-dose escalation study, which demonstrated the feasibility of REYOBIQ for treating LM. The trial is designed in alignment with the FDA's Project Optimus to identify the optimal dosing regimen that maximizes efficacy and safety. The dose optimization study builds on encouraging results from the Company's previously announced Phase 1 trial, which showed a single dose of REYOBIQ delivered up to an average absorbed dose of >250 Gy to the cranial subarachnoid space. It also demonstrated that 5 of 7 patients achieving an over 80% reduction in LM tumor cells in the cerebrospinal fluid survived at least one year post-treatment. The company will also request an End of Phase 1 Type B meeting with the FDA to align on the clinical development plan and the design of a potential registrational trial. REYOBIQ is being evaluated for the treatment of recurrent glioblastoma, leptomeningeal metastase, and pediatric brain cancer in the ReSPECT-GBM, ReSPECT-LM, and ReSPECT-PBC clinical trials.

New major risk - Market cap size The company's market capitalization is less than US$10m. Market cap: US$8.50m This is considered a major risk. Companies with a small market capitalization are most likely businesses that have not yet released a product to market or are simply a very small company without a wide reach. Either way, risk is elevated with these companies because there is a chance the product may not come to fruition or the company's addressable market or demand may not be as large as expected. In addition, if the company's size is the main factor, it is less likely to have many investors and analysts following it and scrutinizing its performance and outlook. Currently, the following risks have been identified for the company: Major Risks Share price has been highly volatile over the past 3 months (48% average daily change). Negative equity (-US$8.9m). Shareholders have been substantially diluted in the past year (298% increase in shares outstanding). Market cap is less than US$10m (US$8.50m market cap). Minor Risk Currently unprofitable and not forecast to become profitable over next 3 years (US$11m net loss in 3 years). Announcement • Apr 19

Plus Therapeutics, Inc. Presents New Data Highlighting Clinical Benefit and Safety of REYOBIQ in the ReSPECT-LM Clinical Trial for Patients with Leptomeningeal Metastases Plus Therapeutics, Inc. announced the online availability of new data on its lead compound REYOBIQ™ (rhenium Re186 obisbemeda) in an abstract for both an oral presentation and a poster to be presented at the Nuclear Medicine and Neurooncology conference to be held May 9-10, 2025 in Vienna, Austria. The abstract, titled, "Rhenium Obisbemeda (REYOBIQ) in Leptomeningeal Metastases," highlights additional data from the Company's completed Phase 1 ReSPECT-LM dose escalation trial demonstrating a dose dependent increase in the average absorbed dose to the cranial and spinal subarachnoid space reaching 253Gy in Cohort 5. Neuroimaging response data was available for 16 patients as of the data cutoff with five of those (31%) showing a partial response. An additional seven patients showed stable disease by neuroimaging through day 112 for a Clinical Benefit Rate (complete response + partial response + stable disease) of 75%. Additionally, a clinical response based on the physician evaluation showed a decrease in disease findings in two of 14 evaluable patients (14%) and 10 patients showed stable findings through day 112 for an 86% Clinical Benefit Rate. The incidence of LM is on the rise, partly because cancer patients are living longer and partly because many standard chemotherapy cannot reach sufficient concentrations in the spinal fluid to kill the tumor cells, yet there are no FDA-approved therapies specifically for LM patients, who often succumb to this complication within weeks to several months, if untreated. REYOBIQ™™ is being evaluated for the treatment of recurrent gllioblastoma and leptomeningeal metastases in the ReSPECT-GBM and ReSPECT-LM clinical trials. Major Estimate Revision • Apr 03

New minor risk - Share price stability The company's share price has been volatile over the past 3 months. It is more volatile than 75% of American stocks, typically moving 12% a week. This is considered a minor risk. Share price volatility indicates the stock is highly sensitive to market conditions or economic conditions rather than being sensitive to its own business performance, which may also be inconsistent. It also increases the risk of potential losses in the short term as the stock tends to have larger drops in price more frequently than other stocks. Currently, the following risks have been identified for the company: Major Risks Negative equity (-US$5.2m). Shareholders have been substantially diluted in the past year (30% increase in shares outstanding). Market cap is less than US$10m (US$6.37m market cap). Minor Risks Currently unprofitable and not forecast to become profitable over next 3 years (US$34m net loss in 3 years).

Plus Therapeutics, Inc. Advances Lead Drug Rhenium (186Re) Obisbemeda for Patients with Leptomeningeal Metastases Plus Therapeutics, Inc. announced the completion of the ReSPECT-LM Phase 1 single-dose escalation trial, having determined an RP2D. The ReSPECT-LM single-dose escalation trial assessed the safety, tolerability, and potential efficacy of intrathecally administered Rhenium (186Re) Obisbemeda in patients with leptomeningeal metastases (LM). Additional details on the ReSPECT-LM trial can be found here. LM occurs in approximately 5% of people with cancer and is usually terminal with 1-year and 2-year survival of just 7% and 3%, respectively. The incidence of LM is on the rise, partly because cancer patients are living longer and partly because many standard chemotherapy cannot reach sufficient concentrations in the spinal fluid to kill the tumor cells, yet there are no FDA-approved therapies specifically for LM patients, who often succumb to this complication within weeks to several months, if untreated.

New Risk • Jan 16
New major risk - Shareholder dilution The company's shareholders have been substantially diluted in the past year. Increase in shares outstanding: 30% This is considered a major risk. Shareholder dilution occurs when there is an increase in the number of shares on issue that is not proportionally distributed between all shareholders. Often due to the company raising equity capital or some options being converted into stock. All else being equal, if there are more shares outstanding then each existing share will be entitled to a lower proportion of the company's total earnings, thus reducing earnings per share (EPS). While dilution might not always result in lower EPS (like if the company is using the capital to fund an EPS accretive acquisition) in a lot cases it does, along with lower dividends per share and less voting power at shareholder meetings. Currently, the following risks have been identified for the company: Major Risks Less than 1 year of cash runway based on free cash flow trend (-US$12m free cash flow). Negative equity (-US$5.2m). Shareholders have been substantially diluted in the past year (30% increase in shares outstanding). Market cap is less than US$10m (US$6.90m market cap).

New major risk - Revenue and earnings growth Earnings are forecast to decline by an average of 2.5% per year for the foreseeable future. This is considered a major risk. Ultimately, shareholders want to see a good return on their investment and that generally comes from sharing in the company's profits. If profits are expected to decline, then in most cases the share price will decline over time as well. In addition, if the company pays dividends it will also likely need to reduce or cut them, striking a dual blow to total shareholder returns. Currently, the following risks have been identified for the company: Major Risks Less than 1 year of cash runway based on free cash flow trend (-US$11m free cash flow). Negative equity (-US$7.6m). Earnings are forecast to decline by an average of 2.5% per year for the foreseeable future. Market cap is less than US$10m (US$7.43m market cap). Minor Risks Currently unprofitable and not forecast to become profitable over next 3 years (US$46m net loss in 3 years). Share price has been volatile over the past 3 months (14% average weekly change). Shareholders have been diluted in the past year (30% increase in shares outstanding). Announcement • Nov 05

New major risk - Share price stability The company's share price has been highly volatile over the past 3 months. It is more volatile than 90% of American stocks, typically moving 15% a week. This is considered a major risk. Share price volatility increases the risk of potential losses in the short-term as the stock tends to have larger drops in price more frequently than other stocks. It may also indicate the stock is highly sensitive to market conditions or economic conditions rather than being sensitive to its own business performance, which may also be inconsistent. Currently, the following risks have been identified for the company: Major Risks Less than 1 year of cash runway based on free cash flow trend (-US$11m free cash flow). Share price has been highly volatile over the past 3 months (15% average weekly change). Negative equity (-US$7.6m). Shareholders have been substantially diluted in the past year (105% increase in shares outstanding). Market cap is less than US$10m (US$8.31m market cap).

Plus Therapeutics Reports ReSPECT-GBM Clinical Trial Update at the 2024 Congress of Neurological Surgeons Annual Meeting Plus Therapeutics, Inc. presented an update on the ongoing ReSPECT-GBM Phase 1/2 clinical trial, evaluating the Company’s lead asset Rhenium (186Re) Obisbemeda for the treatment of recurrent glioblastoma. The data were presented at the 2024 Congress of Neurological Surgeons (CNS) Annual Meeting on September 30, 2024, in Houston, Texas. The presentation, titled “Treatment of Recurrent Glioblastoma (rGBM) via Convection Enhanced Delivery (CED) with Rhenium (186Re) Obisbemeda (Rhenium-186 Nanoliposome, 186RNL): ReSPECT-GBM Phase 1/2 Trial Update” was delivered by lead investigator and neurosurgeon John Floyd, M.D., Associate Professor and Chair of the Department of Neurosurgery at the University of Texas Health Science Center San Antonio. The data highlights the continued favorable safety profile and encouraging efficacy results of Rhenium (186Re) Obisbemeda in a patient population with historically poor prognosis. ReSPECT-GBM is a first-in-human, open-label, Phase 1/2 study investigating feasibility, dose escalation, and critical convection enhanced delivery (CED) parameters to determine the maximum tolerated dose (MTD), maximum feasible dose (MFD), safety, and potential efficacy of Rhenium (186Re) Obisbemeda in recurrent adult glioma (IND 116117). Key Highlights from the ReSPECT-GBM Phase 1/2 Trial Update: 42 total patients have enrolled thus far at 3 sites and with 19/42 patients having been treated to date at the recommended Phase 2 dose (22.3 mCi in 8.8 mL) in tumors of approximately 20 cm3 or less. All Phase 2 patients have recurrent, histologically confirmed glioblastoma; 1 recurrence, bevacizumab naïve, single tumor of approximately 20 cm3 or less (small-to-medium sized tumors). Average tumor size in Phase 2 was 7.5 mL (range 0.9-22.8 mL). Increases in absorbed dose correlated with specific drug delivery parameters such as infused dose and volume, maximal convection flow rate, and number of catheters. Rhenium (186Re) Obisbemeda continues to show a favorable safety profile in the 42 enrolled patients; one dose-limiting toxicity (hemiplegia) has been reported, which was observed in Cohort 8 (41.5 mCi and 16.3 mL). In Phase 2, most adverse events (AEs) were mild (73.5%) or moderate (18.8%), and largely unrelated (37.7%), or unlikely related (27.1%) to the drug. Of the 9 severe adverse events (SAEs), only 2 were related to the study drug. Average absorbed radiation dose to the tumor in Phase 2 was 300 Gy (n=18, 1 patient still under analysis). To date, 88.9% of Phase 2 patients met key CED drug delivery parameters shown to correlate with overall survival, achieving a tumor absorbed dose >100 Gy and radiation coverage of >70%. 29/42 patients treated thus far participated in the Phase 1 dose escalation phase of the trial (Note: as per protocol, 6/42 patients were included in both the Phase 1 and Phase 2 trial arms and related analyses). Phase 1 dose-escalation increased administered doses from 1.0 mCi to 41.5 mCi and volumes from 0.66 mL to 16.3 mL. In terms of objective tumor response based on quantitative image analysis, a statistically significant reduction in tumor volume rate change was seen in tumors receiving > 100 Gy absorbed dose (n=11 patients analyzed to date, p<0.005). Sufficient tumor coverage correlated with tumor control, while regrowth occurred outside treated areas. Announcement • Sep 09

New major risk - Market cap size The company's market capitalization is less than US$10m. Market cap: US$9.13m This is considered a major risk. Companies with a small market capitalization are most likely businesses that have not yet released a product to market or are simply a very small company without a wide reach. Either way, risk is elevated with these companies because there is a chance the product may not come to fruition or the company's addressable market or demand may not be as large as expected. In addition, if the company's size is the main factor, it is less likely to have many investors and analysts following it and scrutinizing its performance and outlook. Currently, the following risks have been identified for the company: Major Risks Negative equity (-US$4.8m). Shareholders have been substantially diluted in the past year (129% increase in shares outstanding). Market cap is less than US$10m (US$9.13m market cap).

Plus Therapeutics, Inc. Announces Validation & Clinical Implementation of Csf-01 Leptomeningeal Cancer Cell Diagnostic Plus Therapeutics, Inc. announced it has successfully completed key validation testing and implementation of its tumor cell enumeration assay, known as CSF-01, to be used initially as an exploratory endpoint in its ReSPECT-LM clinical trials. Plus’ CSF-01 cancer cell enumeration test is an exploratory endpoint in the ReSPECT-LM Phase 1 trial that has shown promise in the trial’s early cohorts. In Phase 1/Part A of the ReSPECT-LM trial presented at the 2023 SNO/ASCO Meeting in San Francisco, Plus showed an average 53% reduction in CSF tumor cells 28 days after a single intrathecal administration of rhenium (186Re) obisbemeda in patients with LM. On December 12, 2023, Plus announced its partnership with K2bio (Houston, Texas) to implement Plus’ CSF-01 diagnostic for LM cancers in the ReSPECT-LM trials. While validated for use in Plus’ clinical development programs, full Clinical Laboratory Improvement Amendments (CLIA) certification is not anticipated until 2025. The ReSPECT-LM trial, including support for CSF-01 testing, is currently receiving grant funding from the Cancer Prevention and Research Institute of Texas (CPRIT). The FORSEE trial was performed by the original developer and licensor of CSF-01 and is a multi-center, prospective clinical trial enrolling patients with breast or non-small cell lung cancer (NSCLC) who have suspicious or confirmed LM. If the FORSEE data is positive, the company intend to work toward increasing commercial reimbursement for the CLIA-certified test and explore partnerships to maximize diagnostic utilization for the broader CNS cancer space. About Leptomeningeal Metastases (LM): LM is a rare complication of cancer in which the primary cancer spreads to the cerebrospinal fluid (CSF) and leptomeninges surrounding the brain and spinal cord. All malignancies originating from solid tumors, primary brain tumors, or hematological malignancies have this LM complication potential with breast cancer as the most common cancer linked to LM, with 3-5% of breast cancer patients developing LM. Additionally, lung cancer, GI cancers, and melanoma can also spread to the CSF and result in LM. LM occurs in approximately 5% of people with cancer and is usually terminal, with a 1-year and 2-year survival of just 7% and 3%, respectively. The incidence of LM is on the rise, partly because cancer patients are living longer and partly because many standard chemotherapies cannot reach sufficient concentrations in the spinal fluid to kill the tumor cells. Yet, there are no FDA-approved therapies specifically for LM patients, who often succumb to this complication within weeks to several months if untreated. About Rhenium (186Re) obisbemeda: Rhenium (186Re) obisbemeda is a novel injectable radiotherapy specifically formulated to deliver directly targeted high-dose radiation in CNS tumors in a safe, effective, and convenient manner to optimize patient outcomes. Rhenium (186Re) obisbemeda has the potential to reduce off-target risks and improve outcomes for CNS cancer patients, versus currently approved therapies, with a more targeted and potent radiation dose. Rhenium-186 is an ideal radioisotope for CNS therapeutic applications due to its short half-life, beta energy for destroying cancerous tissue, and gamma energy for real-time imaging. Rhenium (186Re) obisbemeda is being evaluated for the treatment of recurrent glioblastoma and leptomeningeal metastases in the ReSPECT-GBM and ReSPECT-LM clinical trials. ReSPECT-GBM is supported by an award from the National Cancer Institute (NCI), part of the U.S. National Institutes of Health (NIH), and ReSPECT-LM is funded by a three-year $17.6M grant by the Cancer Prevention & Research Institute of Texas (CPRIT).
