monotherapy compared with standard-of-care ("SOC") in second- and third-line treatment of certain soft tissue sarcoma subtypes. In April 2026, the Company initiated activities to resume enrollment in a limited number of U.S. sites in the INVINCIBLE-3 Study using an FDA-reviewed amended protocol based on important learnings from patients previously enrolled in the study. The Company paused new site activations and patient enrollment in March 2025 due to funding constraints. At that time, the trial had enrolled 21 patients, and the Company continued to treat all patients, maintain the database, conduct pharmacovigilance, and conduct other study-related activities in cooperation with its contract research organizations at significantly reduced ongoing costs. In addition, during this pause, the Company obtained important feedback and recommendations about the trial from key investigators and sarcoma thought leaders, and modifications to the protocol were made. The FDA has reviewed the amended protocol, which will be implemented for new patient enrollment. Submission of documentation necessary for restarting in the EU is in progress. Site activation and patient enrollment rates are expected to increase as sufficient funding is obtained. INVINCIBLE-4 Study: Phase 2 open-label, randomized controlled, multicenter study to analyze the clinical activity, safety, and tolerability of INT230-6 given before SOC in patients with early-stage, operable TNBC (Cohort A) and SOC alone (Cohort B). In July 2026, the Company restarted patient treatment in the INVINCIBLE-4 Study and is currently targeting complete enrollment by the end of 2027. The Company paused new patient enrollment in September 2025 to revise the dosing regimen for patients receiving INT230-6 in Cohort A due to some patients experiencing localized skin irritation near the tumor site. In March 2026, a protocol amendment was approved by the Swissmedic and the Swiss Ethics Committee to use a lower drug volume per tumor volume ratio and a single injection of INT230-6 in Cohort A. In August 2026, the Company opened its first site in France for accrual following EU submission of the modified protocol. Preliminary data from the first 14 patients (seven in each cohort) showed a 71% pathological complete response ("pCR") in patients receiving INT230-6 in Cohort A and a 42% pCR in patients receiving the SOC alone (Cohort B). There was also a 44% reduction in grade 3 adverse events in Cohort A compared with Cohort B and fewer immune-related adverse events when INT230-6 was added prior to the immunochemotherapy. Capital Raises In March 2026, the Company established a $60 million at-the-market ("ATM") facility. During the second quarter of 2026, the Company raised net proceeds of $1.6 million under the ATM. Subsequent to June 30, 2026, the Company has raised additional net proceeds of $1.3 million under the ATM. "We are pleased that the capital raised in 2025 and to date in 2026 provides the resources to reinitiate the Phase 3 INVINCIBLE-3 Study. In addition, during the 2025 pause, we evaluated and modified the protocol based on feedback from key investigators and sarcoma thought leaders. The FDA-reviewed amended protocol will first be implemented in select U.S. sites," stated Lewis H. Bender, Founder, President and CEO of Intensity. "In the Phase 2 INVINCIBLE-4 Study, early data show potential for an improvement in the pCR rate with a reduction in the number of grade 3 adverse events including immune-related adverse
Page 3
events. These preliminary findings are encouraging, and we are excited that investigators have restarted treatment in patients in Switzerland. We look forward to enrolling new patients in this study in France now that sites are being activated. Lastly, we continue to pursue potential partnerships to advance our programs, and held meetings with potential strategic partners at the BIO International Conference in late June. While early, we are pleased with the interest expressed in our science and clinical trials, and we expect to continue discussions in the second half of 2026." Second Quarter 2026 Financial Results Research and development expenses were $1.8 million for the second quarter of 2026, compared with $1.5 million for the same period in 2025. The increase was primarily due to higher INVINCIBLE-3 Study costs as the Company initiated activities to resume enrollment in a limited number of U.S. sites in April. The Company paused new site activations and patient enrollments in March 2025 due to funding constraints. Research and development expenses also increased due to an estimated bonus accrual during the second quarter of 2026 compared with no bonus accrual during the second quarter of 2025, which was partially offset by lower stock-based compensation. General and administrative expenses were $1.3 million for the second quarter of 2026, compared with $1.2 million for the same period in 2025. The increase was due to an estimated bonus accrual during the 2026 quarter compared with no bonus accrual during 2025 quarter, and higher Delaware franchise costs. These increases were partially offset by lower stock-based compensation as no stock-based compensation awards were granted during the first half of 2026. Net loss was $3.0 million for the second quarter of 2026, compared with a net loss of $2.5 million for the second quarter of 2025. As of June 30, 2026, cash and cash equivalents totaled $9.5 million. During the second quarter of 2026, the Company raised $1.7 million under the ATM, for net proceeds of $1.6 million. About Triple Negative Breast Cancer in the Presurgical Setting Women with aggressive forms of breast cancer, such as TNBC, are often counseled to undergo neoadjuvant (presurgical) systemic therapy to reduce the risk of the disease returning. Having a pathological complete response, meaning the absence of live cancer at the time of surgery, has been shown to result in a lower risk of disease recurrence from 50% to 16% at 5 years. Approximately 11% to 17% of breast cancers test negative for estrogen receptors ("ER"), progesterone receptors ("PR"), and overexpression of human epidermal growth factor receptor 2 ("HER2") protein, qualifying them as triple negative. There are approximately 56,000 new cases of TNBC in the US and 420,000 worldwide diagnosed each year, 85% of which are local to the breast. TNBC is considered to be more aggressive and has a poorer prognosis than other types of breast cancer, because there are fewer available targeted medicines. Most patients with local TNBC typically receive immunochemotherapy before surgery. Since the publication of Keynote-522, the standard neoadjuvant treatment for TNBC includes systemic chemotherapy (anthracyclines, cyclophosphamide, paclitaxel, carboplatin) and the anti-PD-1 monoclonal antibody pembrolizumab. pCR rates range from 50% to 65%, depending on tumor size. Rates are generally lower in the larger-sized tumors

or with lymph node metastasis. The toxicity of the Keynote-522 regimen is high, with 77% of patients experiencing grade 3 or higher treatment-related adverse events, including treatment-related adverse events that lead to death in 0.5% of patients. About Sarcoma Soft tissue sarcoma is a rare type of cancer that starts with the growth of cells in the body's soft tissue, such as muscle, fat, blood vessels, nerves, tendons, and linings of the joints. The disease mostly occurs in the arms, legs and abdomen. There are 197,000 patients in the US living with sarcoma and more than 100 types of soft tissue sarcoma, the treatment of which first involves surgery. Other treatments might include radiation therapy and then chemotherapy. Using the U.S. SEER database, the Company estimated that 14,400 patients have regional or distal (metastatic) leiomyosarcoma, liposarcoma, and undifferentiated pleomorphic sarcoma. About INT230-6 INT230-6, Intensity's lead proprietary investigational product candidate, is designed for direct intratumoral injection. INT230-6 was discovered using Intensity's proprietary DfuseRx ℠ technology platform. The drug consists of two proven, potent anti-cancer agents, cisplatin and vinblastine sulfate, and a diffusion and cell penetration enhancer molecule ("SHAO") that non-covalently conjugates to the two payload drugs, facilitating the dispersion of potent cytotoxic drugs throughout tumors and allowing the active agents to diffuse into cancer cells. These agents remain in the tumor, resulting in a favorable safety profile. In addition to local disease control and direct tumor killing, INT230-6 causes a release of a bolus of neoantigens specific to the malignancy, leading to immune system engagement and systemic anti-tumor effects. Importantly, these effects are mediated without immunosuppression, which often occurs with systemic chemotherapy. About Intensity Therapeutics Intensity is a late-stage clinical biotechnology company whose novel engineered chemistry enables aqueous cytotoxic-containing drug formulations to mix and saturate a tumor's dense, high-fat, pressurized environment following direct intratumoral injection. As a result of the saturation, Intensity's clinical trials have demonstrated the ability of INT230-6 to kill tumors and elicit an adaptive immune response within days of injection, representing a new approach to cancer cell death that holds the potential to shift the treatment paradigm and turn many deadly cancers into chronic diseases, even for malignancies that do not respond to conventional immunotherapy. Intensity has completed two clinical studies that enrolled over 200 patients using INT230-6: a Phase 1/2 dose-escalation study in metastatic cancers including sarcomas ( NCT03058289 ), and a Phase 2 randomized controlled clinical trial in locally advanced breast cancer (the "INVINCIBLE-2 Study") ( NCT04781725 ) in women without undergoing chemotherapy prior to their surgery. The Company initiated a Phase 3 trial in soft tissue sarcoma (the "INVINCIBLE-3 Study") ( NCT06263231 ), testing INT230-6 as second- or third-line monotherapy compared with SOC, with overall survival as an endpoint. Intensity also initiated a Phase 2 study in collaboration with The Swiss Group for Clinical Cancer Research, formerly SAKK and now the Swiss Cancer Institute (the "INVINCIBLE-4 Study") ( NCT06358573 ), as part of a Phase 2/3 program evaluating INT230-6 followed by SOC immunochemotherapy and SOC alone for patients with presurgical triple-negative breast cancer. pCR is the endpoint.
