Clinical Development

During fiscal 2026 and subsequent to year-end, the Company reported the following developments relating to its clinical programs, research activities, and scientific and clinical leadership:

• On August 17, 2026, the Company announced the appointment of Markus Loeffler, MD, MBA, as Chief Medical Officer. Dr. Loeffler brings over 30 years of experience in oncology drug development and will oversee the clinical advancement of the Company’s pipeline.  

• On June 30, 2026, the Company announced the appointments of Helen Middleton as General Counsel and David Browning as Vice President of Clinical Operations. Both appointees bring over 30 years of experience in their respective fields, strengthening the Company’s legal, governance, and clinical development capabilities.    

• On February 24, 2026, the Company announced the presentation of data from its CEACAM6-directed antibody-drug conjugate (ADC) program at the 16 th Annual World ADC London conference. The presentation, delivered by Dr. Jonathan Davis, Director of ADC Discovery, highlighted the therapeutic potential of CEACAM6 across multiple epithelial cancers and preclinical data demonstrating the tumor-selective binding profile of the Company’s proprietary anti-CEACAM6 VHH (nanobody).  

• On February 5, 2026, the Company announced the extension of its Research and Exclusive Option Agreement with metaShape Pharma AG covering LEUMUNA™ for adipose tissue-related and metabolic diseases through December 31, 2028. Under the agreement, metaShape is developing the compound, designated MS 001, as an oral co-therapy for GLP-1 receptor agonists, with preclinical data demonstrating improved weight loss outcomes and reduced weight regain following GLP-1 withdrawal. The extension preserves the Company’s strategic optionality in metabolic indications while allowing it to maintain its primary focus on the oncology applications of the compound.  

• On August 13, 2025, the Company announced the publication of a peer-reviewed article by Frontiers in Oncology reporting results from a previously completed Phase I/II clinical study of L-DOS47 as a single agent in patients with advanced non-small cell lung cancer (NSCLC) and titled “Safety of unconventional antibody-drug conjugate L-DOS47 in a Phase I/II monotherapy study targeting advanced NSCLC”.

LDOS007 is a new Phase Ib/Randomized Phase II, open label study to assess L-DOS47 in combination with pembrolizumab as first-line therapy in NSCLC, currently in the planning stage. As the FDA indicated that the Company could proceed without the meeting if the written feedback was sufficiently clear, and given that no additional discussion was deemed necessary, the Company elected to forego the videoconference in favor of preparing the Clinical Trial Application (CTA) as the next step in its interactions with the Agency.

Research & Development

Research & Development expenses for the year ended July 31, 2026, totaled $1,620,000 (2025: $3,558,000). The following table outlines research and development cost expenses for the current and comparative year (in thousands of Canadian dollars):

Research and development expenditures for the year ended July 31, 2026, when compared to the year ended July 31, 2025, decreased by $1,938,000 or 54%. The change in spending during the year was primarily attributable to a reduction of $1,771,000 in research and development program expenditures, reflecting the wind-down of previous clinical development activities, including the LDOS006 study in metastatic pancreatic adenocarcinoma, and the deferral of engagement with external service providers for the next phase of development of L-DOS47 and other pipeline programs pending successful fundraising. Additional reductions in salaries and benefits, primarily resulting from the closure of the Edmonton laboratory, and lower stock-based compensation expenses due to the timing of stock option grants also contributed to the decrease, partially offset by lower research and development investment tax credits.

Operating, General and Administration

Operating, general and administration expenses for the year ended July 31, 2026, totaled $2,019,000 (2025: $1,839,000). The following table outlines operating, general and administration expenses for the current and comparative years (in thousands of Canadian dollars):

Operating, general and administration expenses for the year ended July 31, 2026, when compared to the year ended July 31, 2025, increased by $180,000 or 10%, primarily due to higher stock-based compensation expenses associated with the grant of 1,297,000 stock options in May 2026, of which 490,000 vested immediately, and increased salaries and benefits expenses reflecting the full-year impact of officers appointed in 2025. These increases were partially offset by lower operating, general and administration expenses resulting in changes in accounting service providers and reduced operational activity, as well as lower director fees and investor relations expenses.

Liquidity and Capital Resources

Since its inception, the Company has mainly relied on financing its operations from public and private sales of equity and, more recently, the issuance of convertible debentures. The Company does not have any credit facilities. The Company manages its liquidity risk by continuously monitoring forecasts and actual cash flows from operations, anticipated investment and financing activities, and its contractual financial obligations, including the principal and interest payable on its outstanding convertible debentures.

The Company reported a net loss and total comprehensive loss of $3,354,000 or $0.04 per common share for the year ended July 31, 2026, (July 31, 2025: $5,205,000 or $0.09 per common share). As at July 31, 2026, the Company had a working capital deficiency of $4,181,000, shareholders’ equity of $14,208,000, and an accumulated deficit of $219,230,000.

On May 27, 2026, the Company announced the closing of a non-brokered private placement of unsecured convertible debentures with an aggregate principal amount of $3,673,000. The debentures bear simple interest at a rate of 25% per annum, payable at maturity on July 27, 2027. At the holder’s option, the principal is convertible at maturity into common shares at a conversion price of $1.42 per share, while accrued interest is convertible at the greater of $1.42 or the five-day volume-weighted average price less the 20% discount permitted by the TSX.

During the year ended July 31, 2026, the Company signed a term sheet with Alumni Capital Limited in respect of a potential financing transaction. Consistent with the Company’s confidentiality obligations, the specific commercial terms of the term sheet and potential transaction are not disclosed .

On December 3, 2025, the Company entered into a subscription agreement with Quantum Global Ventures AG for the purchase of 18,538,889 common shares at $1.80 per share, for expected gross proceeds of $33,370,000. The subscription agreement was fully executed by both parties. However, the subscriber subsequently declared bankruptcy, and the Company did not receive any subscription proceeds. As a result, the financing did not close.

During the year ended July 31, 2026, 2,220,000 stock options were cancelled or expired and no stock options were exercised. All 2,031,411 outstanding warrants expired unexercised. On May 21, 2026, the Company granted 1,297,000 stock options with an exercise price of $1.63 per common share, expiring on May 21, 2031. As at July 31, 2026, 2,283,667 stock options were outstanding, of which 1,476,667 were exercisable.

On August 22, 2025, the Company closed a non-brokered private placement financing for gross proceeds of $1,667,000 from the issuance of 2,222,333 Common Shares at a price of $0.75 per Common Share.

Subsequent to July 31, 2026, on September 11, 2026, 500,000 stock options expired unexercised, leaving 1,783,667 stock options outstanding. On September 28, 2026, the Board extended to September 17, 2028 the exercise period of 500,000 vested stock options with exercise prices of $1.10 and $1.30 held by three directors who resigned on September 17, 2026; the incremental fair value will be recognized in the year ending July 31, 2027. The closing price of the Company’s common shares on the TSX was $0.92 on October 8, 2026, below the debenture conversion price of $1.42.

As at July 31, 2026, the Company had cash reserves of $804,000, which are insufficient to meet its anticipated working capital and capital expenditure requirements over the next twelve months or to complete its current research and development initiates. To the extent that the Company does not believe it has sufficient liquidity to meet its current obligations, management considers securing additional funds primarily through equity arrangements to be of utmost importance.

The Company continues to evaluate financing alternatives to support its ongoing operations and planned development activities. Its current financing strategy contemplates securing bridge financing to support near-term corporate objectives and prepare for a subsequent, larger financing intended to fund the next stages of clinical development, including the planned Phase Ib/randomized Phase II study of L-DOS47 in combination with pembrolizumab in first-line non-small cell lung cancer. The timing and execution of these activities remain contingent upon securing sufficient financing and meeting applicable regulatory and development requirements.

The Company’s financial statements, management’s discussion and analysis and annual information form will be filed under the Company’s profile on SEDAR+ at https://www.sedarplus.ca/ , as well as on the Company’s website at www.helixbiopharma.com .
