## Exhibit 99.1

**EXHIBIT 99.1**

**Quantum BioPharma Ltd. Responds to Vague and Misleading Allegations by The Schall Law Firm and DJS Law Group**

TORONTO, Oct. 14, 2025 (GLOBE NEWSWIRE) -- Quantum BioPharma Ltd. (NASDAQ: QNTM) (CSE: QNTM) (FRA: 0K91) (Upstream: QNTM) ("**Quantum BioPharma**" or the "**Company**"), a biopharmaceutical company dedicated to building a portfolio of innovative assets and biotech solutions for the treatment of challenging neurodegenerative and metabolic disorders and alcohol misuse disorders with drug candidates in different stages of development, today issued a formal response to the press releases published by The Schall Law Firm and DJS Law Group on October 9th and 10th , 2025, which announced an investigation into alleged securities law violations by the Company.

The Company strongly refutes the vague and unsubstantiated claims made in the releases, which fail to specify any factual basis or concrete allegations. Specifically, the Schall Law Firm's statement that it is "investigating claims on behalf of investors… for violations of the securities laws" and that the investigation "focuses on whether the Company issued false and/or misleading statements and/or failed to disclose information pertinent to investors" lacks any detail, context, or substantiation. These ambiguous assertions are misleading and appear designed to provoke unwarranted concern among shareholders.

Quantum BioPharma views the Schall Law Firm's and DJS Law Groups announcements as part of a broader pattern of opportunistic litigation tactics that seek to exploit public markets without merit. The Company is reviewing the conduct of both The Schall Law Firm and its principal, Brian Schall, Esq., as well as DJS Law Group and its principal David J Schwartz and will take all appropriate action to address what it believes to be a deliberate attempt to damage its reputation.

We would like to hear from any individual or entity who may have been treated unfairly or unjustly by Schall Law Firm's and DJS Law Groups or their associates. Your identity and information will be kept confidential.

**Forward-Looking Information**

*This press release contains certain "forward-looking statements" within the meaning of applicable securities law. Any statements that express or involve discussions with respect to predictions, expectations, beliefs, plans, objectives, assumptions or future events or performance (often, but not always, identified by words or phrases such as "believes", "hopes", "alleges", "pending", "further", or variations of such words and phrases or statements that certain actions events or results "may", "could", "which", or "will" and similar expressions) are not statements of historical fact and may be forward-looking statements. Forward-looking information herein includes, but is not limited to, statements regarding: the Company's ongoing litigation against major financial institutions; the potential outcome or judgment value; expectations regarding whistleblower submissions and related rewards; continued market integrity initiatives; future business performance and possible acquisitions.*

*In making the forward-looking statements in this news release, the Company has applied several material assumptions, including without limitation: the ability to obtain and validate whistleblower evidence; the timing and outcome of legal proceedings; resolution of ongoing litigation on favourable terms, availability and sufficiency of litigation funding; continued regulatory compliance and market stability for the Company's operations.*

*The Company cautions that forward-looking statements are based on the beliefs, estimates and opinions of the Company's management on the date the statements are made, and they involve a number of risks and uncertainties. Consequently, there can be no assurances that such statements will prove to be accurate and actual results and future events could differ materially from those anticipated in such statements. The above lists of forward-looking statements and assumptions are not exhaustive. Since forward-looking statements address future events and conditions, by their very nature they involve inherent risks and uncertainties. Actual results may differ materially from those currently anticipated or implied by such forward-looking statements due to a number of factors and risks. These include: the adverse outcome of legal actions; the receipt and credibility of whistleblower disclosures; changes in applicable laws and regulations; the actions of third parties involved in alleged manipulation; evolving market dynamics; the sufficiency of future litigation proceeds to fund the Company's whistleblower reward; the continued ability to obtain sufficient litigation funding; limited future growth opportunities, and reliance on key personnel.*

*Except to the extent required by applicable securities laws and the policies of the Canadian Securities Exchange, the Company undertakes no obligation to update these forward-looking statements if management's beliefs, estimates or opinions, or other factors, should change.*
