On February 19, 2026, Moleculin Biotech, Inc. (the "Company") entered into warrant exercise inducement offer letters (each, an "Inducement Letter") with holders of certain existing warrants (the "Holders") to purchase up to 2,122,652 shares of Company common stock with an exercise price of $3.90 per share (the "Existing Warrants").

Pursuant to the Inducement Letter, the Holders agreed to exercise the Existing Warrants, and the Company agreed to issue the Holders new warrants to purchase up to a number of shares of Company common stock equal to 300% of the number of shares of Company common stock underlying the exercised Existing Warrants, comprised of new Series H warrants to purchase up to 6,367,956 shares of Company common stock (the "Inducement Warrants" and the shares of Company common stock underlying the Inducement Warrants, the "Inducement Warrant Shares") with an exercise term of five years from the initial exercise date.

The issuance and/or resale of the shares of Company common stock underlying the Existing Warrants have been registered pursuant to effective registration statements on Form S-1 (File No. 333-287727) and Form S-3 (File No. 333-290418). The Company anticipates receiving aggregate gross proceeds of up to approximately $8.3 million from the exercise of the Existing Warrants before deducting fees and other expenses payable by it.

Each Inducement Warrant has an initial exercise price per share equal to the lesser of (i) $3.90, and (ii) the lowest volume weighted average price of the Company common stock on any trading day during the five trading day period immediately following the public announcement of the Company entering into the Inducement Letters with the Holders, will be exercisable upon the receipt of shareholder approval of the issuance of the Inducement Warrant Shares, and may be exercised for a period of five years from such approval. If while the Inducement Warrants are outstanding, the Company issues or sells, or is deemed to have issued or sold, any common stock and/or common stock equivalents other than in connection with certain exempt issuances, at a purchase price per share less than the exercise price of the Inducement Warrants in effect immediately prior to such issuance or sale or deemed issuance or sale, then immediately after such issuance or sale or deemed issuance or sale, the exercise price of the Inducement Warrants then in effect will be reduced to an amount equal to the new issuance price, subject to a floor price of $0.962.

The Inducement Warrants may only be exercised on a cashless basis if there is no registration statement registering, or the prospectus contained therein is not available for, the resale of the shares of common stock underlying the Inducement Warrants by the Holders. The Holders of an Inducement Warrant may not exercise any such warrants to the extent that such exercise would result in the number of shares of common stock beneficially owned by such Holders and its affiliates exceeding 4.99% or 9.99% (at the election of the Holders) of the total number of shares of common stock outstanding immediately after giving effect to the exercise, which percentage may be increased or decreased at the Holders’ election not to exceed 9.99% (the "Beneficial Ownership Limitation"). In the event of certain fundamental transactions (as defined in the Inducement Warrants), the Holders of the Inducement Warrants will have the right to receive the Black Scholes value of the Inducement Warrants calculated pursuant to a formula set forth in the Inducement Warrants, payable either in cash or in the same type or form of consideration that is being offered and being paid to the Holders of common stock.

The Company agreed to file a registration statement on Form S-3 (or other appropriate form, including Form S-1, if it is not then Form S-3 eligible) providing for the resale of the Inducement Warrant Shares issuable upon the exercise of the Inducement Warrants (the "Resale Registration Statement"), on or before March 31, 2026, and to use commercially reasonable efforts to have such Resale Registration Statement declared effective by the SEC by April 30, 2026 and to keep the Resale Registration Statement effective at all times until no Holders of the Inducement Warrants own any Inducement Warrant Shares.

Roth Capital Partners, LLC served as financial advisor for the transaction and received as compensation for such services a fee of 7.0% of the gross proceeds the Company received from the warrant inducement of the Existing Warrants and reimbursement of $50,000 in legal fees.

The representations, warranties and covenants contained in the Inducement Letter were made solely for the benefit of the parties to the Inducement Letter. In addition, such representations, warranties and covenants: (i) are intended as a way of allocating the risk between the parties to such agreements and not as statements of fact, and (ii) may apply standards of materiality in a way that is different from what may be viewed as material by stockholders of, or other investors in, the Company. Accordingly, the Inducement Letter is filed with this report only to provide investors with information regarding the terms of transaction, and not to provide investors with any other factual information regarding the Company. Information concerning the subject matter of the representations and warranties may change after the date of the Inducement Letter, which subsequent information may or may not be fully reflected in public disclosures.

The forms of the Inducement Warrant and Inducement Letter are filed as Exhibits 4.1 and 10.1, respectively, to this Current Report on Form 8-K.

On February 19, 2026 bioAffinity Technologies, Inc. (Nasdaq: BIAF; BIAFW), a biotechnology company advancing noninvasive diagnostics for lung cancer and other lung diseases, reported a new clinical case study in which its CyPath Lung noninvasive diagnostic test for lung cancer helped determine the appropriate treatment for a 79-year-old female with a suspicious lung finding on a low-dose computed tomography (LDCT) scan.

The patient, a current smoker with a medical history significant for chronic obstructive pulmonary disease (COPD) and coronary heart disease, underwent LDCT screening in June 2025. Imaging revealed a spiculated, or irregularly shaped, nodule about half an inch in size at the bottom of the right lung, near the lining of the lung. Spiculated nodules raise concerns about malignancy due to their uneven, irregular appearance.

"Spiculated findings on CT scans often trigger concern and can lead to invasive procedures, particularly in older high-risk patients," said Daya Nadarajah, MD, the patient’s pulmonologist. "Given this patient’s age, smoking history and comorbidities, we were not comfortable proceeding directly to an invasive procedure. CyPath Lung gives us objective data to better stratify risk and avoid putting our patients through unnecessary and potentially risky procedures."

The CyPath Lung test result was negative, indicating an unlikely malignancy in the lung and supporting a conservative management approach that includes annual CT screening. A repeat scan in October 2025 showed that the suspicious finding from the June scan had resolved, and there were no pulmonary nodules in the lungs.

"Every suspicious finding is concerning. Even when the probability of malignancy is low, the consequences of missing a cancer are significant," said Gordon Downie, MD, PhD, bioAffinity Technologies Chief Medical Officer. "Physicians now have a tool in CyPath Lung that further refines risk and provides valuable reassurance when deciding whether to monitor or escalate care."

Supporting Confident, Noninvasive Management

Based on the reassuring imaging and negative CyPath Lung result, the patient and her care team agreed to continue with serial annual CT scans as follow-up care. In this case, CyPath Lung:

Provided the confidence to defer invasive procedures
Prevented an unnecessary biopsy
Put the patient at ease with ongoing surveillance
Complemented imaging findings in a high-risk individual
About CyPath Lung

CyPath Lung by bioAffinity Technologies is a noninvasive test designed to improve the early detection of lung cancer in patients at high risk for the disease. CyPath Lung uses advanced flow cytometry and proprietary artificial intelligence (AI) to identify cell populations in patient sputum that indicate malignancy. CyPath Lung incorporates a fluorescent porphyrin that is preferentially taken up by cancer and cancer-related cells. Clinical study results demonstrated 92% sensitivity, 87% specificity and 88% accuracy in detecting lung cancer in patients at high risk for the disease who had small indeterminate lung nodules less than 20 millimeters.

ENHERTU is a specifically engineered HER2 directed DXd antibody drug conjugate (ADC) discovered by Daiichi Sankyo (TSE: 4568) and being jointly developed and commercialized by Daiichi Sankyo and AstraZeneca (LSE/STO/NYSE: AZN).

The validation confirms the completion of the application and commences the scientific review process by the EMA’s Committee for Medicinal Products for Human Use (CHMP). The application is based on data from the DESTINY-Breast05 phase 3 trial presented at the 2025 European Society for Medical Oncology (#ESMO25) Congress and subsequently published in The New England Journal of Medicine. In the trial, ENHERTU demonstrated a statistically significant and clinically meaningful improvement in invasive disease-free survival (IDFS) versus trastuzumab emtansine (T-DM1) in patients with HER2 positive breast cancer with residual invasive disease following neoadjuvant therapy.

"Patients who have residual invasive disease despite neoadjuvant therapy face a heightened risk of recurrence and are in need of better options following neoadjuvant treatment and surgery," said Ken Takeshita, MD, Global Head, R&D, Daiichi Sankyo. "This validation in the EU is an important step toward bringing ENHERTU to eligible patients earlier in the treatment journey to help reduce the risk of disease recurrence and progression to metastatic disease."

Additional regulatory submissions for ENHERTU also are underway in the EU, including in combination with pertuzumab for the first-line treatment of adult patients with unresectable or metastatic HER2 positive breast cancer based on data from DESTINY-Breast09 and for previously treated HER2 positive unresectable or metastatic solid tumors based on data from DESTINY-PanTumor02, DESTINY-CRC02 and DESTINY-Lung01.

About DESTINY-Breast05
DESTINY-Breast05 is a global, multicenter, randomized, open-label, phase 3 trial evaluating the efficacy and safety of ENHERTU (5.4 mg/kg) versus T-DM1 in patients with HER2 positive early breast cancer with residual invasive disease in breast or axillary lymph nodes following neoadjuvant therapy and a high risk of recurrence. High risk of recurrence was defined as presentation with inoperable cancer (prior to neoadjuvant therapy) or pathologically positive axillary lymph nodes following neoadjuvant therapy.

The primary endpoint of DESTINY-Breast05 is investigator-assessed IDFS, which is defined as the time from randomization until first invasive local, axillary or distant recurrence or death from any cause. The key secondary endpoint is investigator-assessed disease-free survival. Other secondary endpoints include overall survival, distant recurrence-free interval, brain metastases-free interval and safety.

DESTINY-Breast05 enrolled 1,635 patients in Asia, Europe, North America, Oceania and South America. For more information about the trial, visit ClinicalTrials.gov.

About Post Neoadjuvant Treatment for HER2 Positive Early Breast Cancer
Breast cancer is the second most common cancer and one of the leading causes of cancer-related deaths worldwide.1 More than two million breast cancer cases were diagnosed in 2022, with more than 665,000 deaths globally.1 In Europe, approximately 557,000 cases of breast cancer are diagnosed annually, with more than 144,000 deaths.1

HER2 is a tyrosine kinase receptor growth-promoting protein expressed on the surface of many types of tumors including breast cancer.2 HER2 protein overexpression may occur as a result of HER2 gene amplification and is often associated with aggressive disease and poor prognosis in breast cancer.2 Approximately one in five cases of breast cancer is considered HER2 positive.3

For patients with HER2 positive early breast cancer, achieving pathologic complete response (pCR) with neoadjuvant treatment is the earliest indicator of improved long-term survival.4 However, approximately half of patients who receive neoadjuvant treatment do not experience pCR, putting them at increased risk of disease recurrence.5,6,7,8,9

Despite receiving additional treatment for residual disease in the post-neoadjuvant setting, some patients still experience invasive disease or death and current treatment options have shown limited impact on central nervous system recurrence.10 Once patients are diagnosed with metastatic disease, the five-year survival rate drops from nearly 90% to approximately 30%.11

Post-neoadjuvant therapy represents a key opportunity to minimize the risk of recurrence and prevent progression to metastatic disease for patients with residual disease. New treatment options are needed in the early breast cancer setting to help reduce the likelihood of disease progression and improve long-term outcomes for more patients.12,13

In a syngeneic CT26 model, murine STC-1010 significantly inhibits tumor growth and extends survival by 40%. New mechanistic datas reveal expansion of CD4⁺ and CD8⁺ T cells in draining lymph nodes alongside a significant humoral response compared to control, demonstrating coordinated cellular and humoral immune activation in vivo.

Other findings show that dendritic cells efficiently capture STC-1010, leading to their activation as demonstrated by transcriptomic analysis revealing significant upregulation of key immune pathways in an ex vivo model compared to controls. These activated dendritic cells process and present STC-1010 antigens, as demonstrated by detection of STC-1010’s peptides at both intracellular (processed antigen) and surface (presented antigen) levels. They then prime autologous CD8⁺ T cells that mediate robust, reproducible cytotoxicity (tumor killing) against colorectal cancer cells, with consistent apoptosis rates across pilot and GMP production batches.

The first-in-human BreAK CRC 001 phase I/IIa trial (NCT06934538) was launched in patients with unresectable, metastatic, or locally advanced CRC to assess the safety and efficacy of STC-1010 in first-line combined with standard-of-care. Preliminary data from MSS + KRAS-mutant CRC patients indicated a good safety profile, with no dose-limiting toxicities. Phase Ia complete safety data and exploratory efficacy across dose cohorts expected in Q2 2026. Link to abstract: here, Poster #A061.
