Oncolytics Biotech (ONCY) doubles Q1 loss and warns on going concern

Rhea-AI Filing Summary

Oncolytics Biotech Inc. reported a larger quarterly loss and highlighted funding risk as it advances its cancer pipeline. For the three months ended March 31, 2026, net loss widened to $9.2 million, or $0.08 per share, from $4.7 million a year earlier as research and development and general and administrative expenses both roughly doubled.

Cash and cash equivalents were $5.5 million, and operating activities used $7.3 million of cash. Management stated that existing cash, even with access to equity distribution arrangements, is not sufficient to fund planned operations for at least twelve months, raising substantial doubt about the company’s ability to continue as a going concern unless additional financing is secured.

To bolster liquidity, the company raised net proceeds of $7.6 million by selling 7.4 million common shares through at-the-market offerings and later entered a new sales agreement allowing issuances of up to $75 million. Oncolytics continues to focus on pelareorep, its immunotherapy candidate, including a new randomized Phase 2 colorectal cancer trial and Fast Track Designation in RAS‑mutated metastatic colorectal cancer.

Positive

• None.

Negative

• Going concern uncertainty: Management states that existing cash and available equity distribution capacity are not sufficient to fund planned operations for at least twelve months, raising substantial doubt about the company’s ability to continue as a going concern without additional financing.

Insights

Biotech equity analyst

Quarter shows pipeline progress but a sharper loss and clear going‑concern risk.

Oncolytics increased investment in its pelareorep programs, driving operating expenses to $9.3 million in Q1 2026 from $5.0 million a year earlier. Net loss nearly doubled to $9.2 million as the company advanced a randomized Phase 2 colorectal cancer study and other GI‑focused trials.

Cash was only $5.5 million at March 31, 2026, while operating cash outflow reached $7.3 million for the quarter. Management explicitly stated that current resources, even with equity distribution capacity, do not fund operations for twelve months, triggering substantial doubt about going concern.

The company raised $7.6 million via at‑the‑market offerings in Q1 and later added a new agreement for up to $75 million, but actual impact depends on market conditions and investor demand. Subsequent filings and clinical milestones in 2026 will clarify whether financing and trial progress can support the development strategy.

6 terms

Going concern financial

"These conditions raise substantial doubt about our ability to continue as a going concern."

A going concern is a business that is expected to continue its operations and meet its obligations for the foreseeable future, rather than shutting down or selling off assets. This assumption matters to investors because it indicates stability and ongoing profitability, making the business a more reliable investment. Think of it as believing a restaurant will stay open and serve customers, rather than closing down suddenly.

Fast Track Designation regulatory

"The FDA granted our application, awarding Fast Track Designation for this indication in 2026."

A "fast track designation" is a process that speeds up the review and approval of a product or project, allowing it to reach the market or be completed more quickly than usual. For investors, it can signal that a product may become available sooner, potentially leading to earlier revenue or benefits, and indicating a priority status that might influence company performance and market opportunities.

at-the-market offering agreements financial

"we sold 7,446,574 common shares for gross proceeds of $7,861 at an average price of $1.06 per share."

Therapeutic Accelerator Award financial

"we were selected by the Pancreatic Cancer Action Network as the recipient of its Therapeutic Accelerator Award"

Inducement Share Awards financial

"Inducement Share Awards will vest upon our entry into a definitive agreement involving either the acquisition of our company or the exclusive license of pelareorep."

contract liability financial

"Our contract liability balance at March 31, 2026 and December 31, 2025, which we expect to record in revenue over the next five years"

A contract liability is a legally binding obligation a company has under a contract to deliver goods, services, or a refund in the future in exchange for money or another benefit already received. Investors care because these obligations represent future cash outflows or performance risks—like an IOU on a household chore list—that can reduce available cash, affect earnings reliability, and change how risky or valuable a company’s financial position looks.

Note 1: Nature of Operations

Oncolytics Biotech Inc. is a Nevada corporation. The Company was originally incorporated on April 2, 1998, and completed a change in jurisdiction to the State of Nevada on March 31, 2026. This change in jurisdiction had no impact on our operations. Our shares are publicly traded on the Nasdaq Capital Market. Our principal place of business is located at 4350 Executive Drive, Suite 325, San Diego, California, U.S.

Unless otherwise indicated, all references in these financial statements to the terms “we,” “our,” “us,” “the Company,” and “Oncolytics” may refer, as the context requires, to Oncolytics Biotech Inc., or collectively to Oncolytics Biotech Inc. and its subsidiaries.

We are a clinical-stage biopharmaceutical company developing pelareorep, a well-tolerated intravenously delivered immunotherapeutic agent that activates the innate and adaptive immune systems and weakens tumor defense mechanisms. This improves the ability of the immune system to fight cancer, making tumors more susceptible to a broad range of oncology treatments. Our primary focus is to position pelareorep as a platform immunotherapy for the treatment of gastrointestinal (“GI”) tumors and advance our GI program to registration-enabled clinical studies. We are exploring opportunities for registrational programs and investigator-sponsored trials in metastatic pancreatic cancer, second-line or later anal cancer, and metastatic colorectal cancer.

Going Concern

These condensed consolidated financial statements have been prepared assuming we will continue as a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. Accordingly, these condensed consolidated financial statements do not include any adjustments relating to the recoverability of assets and classification of liabilities that might be necessary should we be unable to continue as a going concern. Such adjustments could be material.

We have incurred operating losses since inception and expect to continue to incur losses for the foreseeable future as we advance the development of pelareorep and incur research and development, manufacturing, and general and administrative expenses. We do not expect to generate significant revenues unless and until pelareorep receives regulatory approval and becomes commercially viable.

As of March 31, 2026, we had cash and cash equivalents of $5,493. Based on our current operating plan, we expect that our existing cash resources, even when considered together with capital that may be raised under our equity distribution arrangements, are sufficient to fund near‑term operating milestones but are not sufficient to fund our planned operations for at least twelve months from the date of issuance of our condensed consolidated financial statements included in this quarterly report. These conditions raise substantial doubt about our ability to continue as a going concern.

Our ability to continue as a going concern depends on our ability to obtain additional financing to fund ongoing operations. Management has plans to raise additional capital, including through the use of our at‑the‑market equity sales agreement and potential strategic collaborations or other financing arrangements. However, there can be no assurance that we will be able to obtain additional financing when needed, on acceptable terms, or at all. If we are unable to obtain additional funding as required, we may need to reduce or delay research and development activities, scale back operations, or pursue strategic alternatives.

Liquidity and Capital Resources

To date, we have funded our operations mainly through issuing share capital via public offerings, equity distribution arrangements, and the exercise of warrants. Until such time as we can generate revenue from product licensing or sales, if ever, we expect to finance our operations through public or private equity or debt financings or other capital sources, which may include strategic collaborations or other arrangements with third parties. If we are unable to raise capital or enter into such other arrangements as and when needed, we may have to significantly delay, scale back or discontinue our planned expenditures.

Our primary use of cash and cash equivalents is to fund operating expenses, which consist of research and development and general and administrative expenditures. Factors that will affect our future capital requirements include, but are not limited to, expansion of our clinical trial program; the timing of patient enrollment in our clinical trials; the actual costs incurred to support each clinical trial; the number of treatments each patient will receive; the timing of activity with our clinical trial research

collaborations; the number, timing and costs of manufacturing runs required to conclude the validation process and supply product to our clinical trial program; the level of collaborative activity undertaken; and the general and administrative services required to support our operations.

Note 2: Basis of Presentation

These condensed consolidated financial statements and notes hereto have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Regulation S-X of the U.S. Securities and Exchange Commission (“SEC”). Accordingly, the condensed consolidated financial statements do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. These condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements prepared in accordance with U.S. GAAP that are contained in our Annual Report on Form 10-K for the year ended December 31, 2025, filed with the SEC on March 30, 2026. These condensed consolidated financial statements reflect all normal and recurring adjustments necessary for a fair statement of our financial position and results of operations for the interim periods. The operating results for the interim periods presented are not necessarily indicative of the results expected for the full year or for any other subsequent interim period. Our condensed consolidated financial statements include our financial statements and the financial statements of our wholly owned subsidiaries, Oncolytics Biotech (Barbados) Inc., Oncolytics Biotech (U.S.) Inc. and Oncolytics Biotech (Canada) Inc. All intercompany accounts and transactions have been eliminated in consolidation.

Use of Estimates, Judgments and Assumptions

The preparation of financial statements in conformity with U.S. GAAP requires management to make certain estimates, judgments, and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. On an ongoing basis, we evaluate the estimates used, which include but are not limited to revenue recognition, estimation of research and development costs incurred, valuation of stock-based compensation, valuation of warrant derivatives, the discount rate used in estimating the present value of right-of-use assets and lease liabilities, deferred income taxes, determination of the functional currency of each of our legal entities, and forecasting future cash flows in assessing our going concern assumption.

Note 3: Summary of Significant Accounting Policies

The condensed consolidated financial statements have been prepared using accounting policies that are consistent with the policies used in preparing the Company’s audited consolidated financial statements for the year ended December 31, 2025.

Functional and Reporting Currency

Management uses its judgment to determine the functional currency that most accurately represents the economic effects of the underlying transactions, events and conditions and considered various factors including the currency of historical and future expenditures and the currency in which funds from financing activities are generated. A company’s functional currency is only changed when there is a material change in the underlying transactions, events and conditions.

Effective January 1, 2026, the functional currency of Oncolytics Biotech Inc. and its subsidiary, Oncolytics Biotech (Barbados) Inc. was changed to the United States (U.S.) dollar (“USD”) from the Canadian dollar. The change was made to reflect that U.S. dollars has become the currency of the primary economic environment in which the Company operates, accounting for a significant part of the Company’s labor, operations and financing.

The change in functional currency was accounted for prospectively in accordance with ASC 830 – Foreign Currency Matters. Accordingly, translated balances at December 31, 2025 became the new accounting basis at January 1, 2026. Results of operations prior to the change were not restated.

These consolidated financial statements are presented in USD, unless otherwise stated.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents and other receivables from the Pancreatic Cancer Action Network (see Note 4) in the event of non-performance by counterparties, but we do not anticipate such non-performance. We maintain our cash and cash equivalents at accredited

ONCOLYTICS BIOTECH INC.

Notes to the Condensed Consolidated Financial Statements

(unaudited)

(in thousands, except share and per share amounts and where indicated)

financial institutions. At times, such balances may exceed federally insured limits. We do not believe we are exposed to any significant credit risk with respect to these balances, as we place our cash and cash equivalents with high‑quality financial institutions and have not experienced any losses on such accounts.

Fair Value Measurement

U.S. GAAP defines fair value, establishes a consistency framework for measuring fair value and specifies disclosure for each major asset and liability category measured at fair value on either a recurring basis or nonrecurring basis. Fair value is the price that would be received to sell an asset, or paid to transfer a liability in an orderly transaction between market participants, at the measurement date. In determining the fair value measurement of our financial instruments, we prioritize the related inputs used in measuring fair value into the following hierarchy:

Level 1 – Quoted prices (unadjusted) in active markets for identical assets or liabilities;

Level 2 – Inputs other than quoted prices included within Level 1 that are either directly or indirectly observable;

Level 3 – Unobservable inputs in which little or no market activity exists, therefore requiring an entity to develop its own assumptions about the assumptions that market participants would use in pricing.

As of March 31, 2026, the carrying amount of our financial instruments, including cash and cash equivalents, other receivables, accounts payable, accrued liabilities, and other liabilities, approximated their fair value due to their short-term maturity.

Stock-Based Compensation

Awards of options that provide for an exercise price that is not denominated in: (a) the currency of a market in which a substantial portion of the Company’s equity securities trades in, (b) the currency in which the employee’s pay is denominated, or (c) the functional currency of the employer’s operations, are required to be classified as liabilities. Following the change in functional currency effective January 1, 2026, certain outstanding stock options with a Canadian dollar exercise price were reclassified from equity-classified to liability-classified options. The reclassification is accounted for as a share option modification in accordance with ASC 718 – Compensation – Stock Compensation (“ASC 718”). Under ASC 718, when an award is reclassified from equity to liability, if at the reclassification date the original vesting conditions are expected to be satisfied, then the minimum amount of compensation cost to be recognized is based on the grant date fair value of the original award. Fair value changes below this minimum amount are recorded in additional paid-in capital. For each reporting period after the modification date, the stock option liability is adjusted so that it equals the portion of the requisite service provided multiplied by the modified award’s fair value at the end of the reporting period. Increases in the fair value of the liability in excess of the minimum grant date compensation cost described above are recognized as stock-based compensation in operating expenses in the condensed consolidated statements of operations and comprehensive loss. For all grants of liability-classified option awards, the compensation cost is remeasured at each reporting period until the settlement date.

Future Accounting Pronouncements

In November 2024, the FASB issued ASU No. 2024-03, Income Statement–Reporting Comprehensive Income–Expense Disaggregation Disclosures (Subtopic220-40) Disaggregation of Income Statement Expenses, which requires public entities to disclose additional information about specific expense categories in the notes to the financial statements on an interim and annual basis. In January 2025, the FASB issued ASU No. 2025-01, Income Statement–Reporting Comprehensive Income–Expense Disaggregation Disclosures (Subtopic 220–40): Clarifying the Effective Date. The amendments in ASU 2025-01 clarified that ASU 2024-03 is effective for annual reporting periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027. Early adoption is permitted. We are currently evaluating the potential impact of the adoption of ASU 2024-03 on our consolidated financial statement disclosures.

Under the terms of the award agreement, we are entitled to receive up to $5,000 in funding for eligible research expenses, and we must comply with the conditions set out in the award agreement, including providing periodic performance progress reports.

Funding received for the three months ended March 31, 2026 and 2025 was nil. During the three months ended March 31, 2026 and 2025, we recognized $390 and $756, respectively, as a reduction of research and development expenses based on eligible costs incurred in accordance with the agreement.

As of March 31, 2026 and December 31, 2025 eligible research and development expenditures incurred exceeded cumulative funding received to date, resulting in other receivables of $917 and $527, respectively.

Note 5: Leases

Our operating lease costs were $73 for each of the three months ended March 31, 2026 and 2025. Our variable lease costs were $16 for each of the three months ended March 31, 2026 and 2025.

Note 6: Common Shares

Authorized Share Capital

We are authorized to issue 1,000,000,000 shares of common stock, par value of $0.001 per share. Holders of our common stock are entitled to one vote per share at meetings of shareholders, to receive such dividends as declared by our board of directors (“Board”), and to receive our remaining property and assets upon dissolution or wind up. Our common shares are not subject to any future call or assessment and there are no pre-emptive, conversion, sinking fund or redemption rights attached to such shares. Our shareholders have no liability to further capital calls as all shares issued and outstanding are fully paid and non-assessable. No other classes of shares are currently permitted to be issued.

At-the-Market Offering Agreements

On October 17, 2025, we entered into an ATM offering agreement with BTIG, LLC, which allows us to issue common shares, at prevailing market prices, with an aggregate offering value of up to $50,000 through the facilities of the Nasdaq Capital Market. During the three months ended March 31, 2026, we sold 7,446,574 common shares for gross proceeds of $7,861 at an average price of $1.06 per share. We received net proceeds of $7,614 after issuance costs of $247 (including commissions of $236). This ATM agreement was terminated on March 21, 2026. On April 6, 2026, we entered into an Open Market Sale Agreement with Jefferies LLC (see Note 12).

On August 2, 2024, we entered into an ATM offering agreement with Cantor Fitzgerald & Co, which allowed us to issue common shares, at prevailing market prices, with an aggregate offering value of up to $50,000 over a 25-month period through the facilities of the Nasdaq Capital Market. During the three months ended March 31, 2025, we sold 5,302,950 common shares for gross proceeds of $4,327 at an average price of $0.82 per share. We received net proceeds of $4,183 after issuance costs of $144 (including commissions of $130). This ATM agreement was terminated on August 22, 2025.

Consultant Services Shares Issued

During the three months ended March 31, 2026, we issued 650,000 common shares to consultants valued at $539, or a weighted-average price of $0.83 per share, as partial or total consideration for services received. We measured the fair value of these services based on the fair value of our common shares on the date we entered into each underlying consulting services agreement. We recognize stock-based compensation expense for these agreements over the time period we expect to receive services. For the three months ended March 31, 2026, we recognized stock-based compensation expense of $730 related to consultant services. As of March 31, 2026 and December 31, 2025, we recorded $93 and $283 in prepaid expenses related to services not yet performed.

Compensation Warrants

In consideration of the services rendered by the underwriter as part of a public offering in 2023, we issued 536,693 compensation warrants. Each compensation warrant is exercisable into one common share at an exercise price of $2.25 up to 60 months from the date of issuance. At the issuance date, we used the Black-Scholes Model to estimate the fair value of the services rendered. The resulting fair value was included as part of the public offering transaction costs, and was allocated to share issue costs and operating expenses based on the relative fair values of the common share and warrant of each unit issued. As of March 31, 2026 and March 31, 2025, there were 536,693 compensation warrants outstanding.

Warrants

Following the change in functional currency on January 1, 2026, warrants issued in 2023 pursuant to an underwritten public offering no longer met liability classification and as such were reclassified as equity at that date. The warrants have an exercise price denominated in U.S. dollars and are indexed to our stock because of the change in functional currency.

Each warrant entitles the holder to purchase one common share at an exercise price of $2.81 up to 60 months from the date of issuance. The expiration of the warrants may be accelerated by us at any time prior to the expiration date if the volume weighted-average price of the issued and outstanding common shares on the Nasdaq Stock Market is greater than $6.50 for any 20 consecutive trading days, at which time we may, within 10 business days, accelerate the expiration date by issuing a press release announcing the reduced warrant term whereupon the warrants will expire on or after the 75th calendar day after the date of such press release. As of March 31, 2026 and March 31, 2025, there were 7,667,050 warrants outstanding.

Note 7: Stock-Based Compensation

Amended and restated Stock Option and Incentive Share Award Plans

Our amended and restated Stock Option Plan and Share Award Plan (collectively, the “Equity Incentive Plans”) were approved

by our shareholders on May 9, 2023. The Equity Incentive Plans provide for the grant of stock options, restricted share unit awards and performance share unit awards to our employees, consultants and directors. Upon the effective date of the 2026 Plan described below, we ceased granting awards under the Equity Incentive Plans, but any awards granted under the Equity Incentive Plans will remain subject to the terms of the applicable plans.

2026 Incentive Award Plan

The 2026 Incentive Award Plan (the “2026 Plan”) was approved by our shareholders at a Special Meeting of Shareholders held on January 15, 2026 and became effective on March 31, 2026. The 2026 Plan provides for the grant of options, including incentive stock options and nonqualified stock options, restricted stock, dividend equivalents, restricted stock units (“RSUs”), performance shares, other incentive awards, stock appreciation rights and cash awards, to our employees, consultants and directors.

The number of shares reserved for issuance under the 2026 Plan equals the sum of (i) 6,500,000 shares; (ii) any shares that remain available under the prior Equity Incentive Plans, as defined below; (iii) any shares that are subject to awards under the prior Equity Incentive Plans which are forfeited or lapse unexercised and which are not issued under the prior Equity Incentive Plans; and (iv) an annual increase on the first day of each calendar year beginning January 1, 2027 and ending on and including January 1, 2036, equal to the lesser of (A) 6% of the aggregate number of shares outstanding on the final day of the immediately preceding calendar year and (B) such smaller number of shares as is determined by the Board or the compensation committee.

As of March 31, 2026, we had 9,986,795 and 12,771,148 common shares reserved for issuance relating to the 2026 Plan and the Equity Incentive Plans, respectively. As of March 31, 2026, there were 9,986,795 common shares available for grant under the 2026 Plan.

Inducement Equity Awards

We have granted inducement equity awards to certain of our key executives. These awards included stock options subject to a service condition, performance-based stock options (collectively, the “Inducement Stock Options”), and performance-based restricted share award units (“Inducement Share Awards”). The grants were made as a material inducement to employment in accordance with Nasdaq Listing Rule 5635(c)(4), and therefore did not require shareholder approval.

Stock-Based Compensation Expense

Our stock-based compensation expense was as follows:

						Three Months Ended March 31,
						2026						2025
Stock-based compensation expense:
Pursuant to Equity Incentive Plans and Inducement Equity Awards						$	2,299					$	845
Pursuant to consulting service agreements						730						—

i.The weighted-average exercise prices reflect the conversion of Canadian dollar denominated stock options translated into U.S. dollars using the applicable foreign exchange rate as of the date of grant.

As of March 31, 2026, unrecognized compensation expense related to unvested stock options was $4,220, including $97 of compensation cost related to unvested stock options with a performance condition. These costs are expected to be recognized over a remaining weighted-average period of 1.6 years.

Stock option grants subject only to a service condition typically vest either immediately or annually over periods ranging from one to three years. The performance-based Inducement Stock Options will vest in full upon us generating a minimum of $25,000 in cumulative proceeds from new financing transactions.

We use the Black-Scholes Model to estimate fair value. We use historical data to estimate the expected dividend yield and expected volatility of our stock in determining the fair value of the stock options. The risk-free interest rate is based on the U.S. Treasury rate applicable to the expected life of the award. The expected dividend yield is zero, as we do not expect to pay dividends for the foreseeable future.

The fair value of options granted during the three months ended March 31 was determined using the following weighted average assumptions:

						2026
Risk-free interest rate						3.8 %
Expected life (years)						5.0
Expected volatility						72.2		%
Expected dividend yield						— %
Weighted-average grant date fair value						$	0.60

As of March 31, 2026, unrecognized compensation expense related to non-vested RSUs was $128. These costs are expected to be recognized over a remaining weighted-average period of 1.0 year.

Inducement Share Awards

Inducement Share Awards will vest upon our entry into a definitive agreement involving either the acquisition of our company or the exclusive license of pelareorep. During the three months ended March 31, 2026, we granted 300,000 Inducement Share Awards. If the performance condition for these awards is met, our CEO will be entitled to receive a number of common shares equal to 2% of our then-outstanding common shares (2,322,563 at March 31, 2026), and certain key executives will be entitled to receive 800,000 common shares. Accordingly, if the performance conditions had been met on March 31, 2026, a total of 3,122,563 common shares would be issuable pursuant to the Inducement Share Awards. Compensation expense for these awards will be recognized if and when the performance condition becomes probable or is achieved. To date, we have not recorded any compensation expense related to these awards.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations should be read together with our condensed consolidated financial statements and related notes included elsewhere in this quarterly report and our audited financial statements and related notes included in our annual report on Form 10-K for the year ended December 31, 2025. The following discussion contains forward-looking statements that involve numerous risks and uncertainties. Our actual results could differ materially from the results described in or implied by these forward-looking statements. See “Cautionary Note Regarding Forward-Looking Statements” for additional cautionary information.

All references to the terms “we,” “our,” “us,” “the Company,” and “Oncolytics” may refer, as the context requires, to Oncolytics Biotech Inc., or collectively to Oncolytics Biotech Inc. and its subsidiaries. Unless otherwise indicated, all references to “$” and “dollars” in this management’s discussion and analysis of financial condition and results of operations mean thousands of U.S. dollars.

Company Overview

We are a clinical-stage biopharmaceutical company developing pelareorep, a well-tolerated intravenously delivered immunotherapeutic agent that selectively replicates in RAS-mutated tumors and activates the innate and adaptive immune systems and weakens tumor defense mechanisms. This improves the ability of the immune system to fight cancer, making tumors more susceptible to a broad range of oncology treatments.

Pelareorep is a proprietary isolate of reovirus, a naturally occurring, non-pathogenic double-stranded RNA virus commonly found in environmental waters. Pelareorep has shown promising results in changing the tumor microenvironment (“TME”). This creates a more immunologically favorable TME, making the tumor more susceptible to various treatment combinations. These treatments include chemotherapies, checkpoint inhibitors, and other immuno-oncology approaches such as CAR T therapies, bispecific antibodies, and RAS or CDK4/6 inhibitors. Pelareorep induces a new army of tumor-reactive T cells, helps these cells to infiltrate the tumor through an inflammatory process, and upregulates the expression of PD-1/PD-L1. By priming the immune system with pelareorep, we believe we can increase the proportion of patients who respond to various cancer treatments, including immunotherapies, especially in cancers where existing treatment regimens have failed or provided limited benefit.

As our clinical development program advances, we anticipate pelareorep’s ability to enhance innate and adaptive immune responses within the TME will play an increasingly important role. This greatly increases opportunities for expanding our clinical program, business development, and partnering opportunities to address gastrointestinal cancers in combination with various therapies. We believe this approach has the most promise for generating clinically impactful data and offers the most expeditious path to regulatory approval.

Our primary focus is to position pelareorep as a platform immunotherapy for the treatment of gastrointestinal (“GI”) cancers and advance our GI programs to registration-enabled clinical studies. We are exploring opportunities for registrational programs and investigator-sponsored trials in metastatic colorectal cancer, second-line or later anal cancer, and metastatic pancreatic cancer.

Going Concern

We have incurred operating losses since inception and expect to continue to incur losses for the foreseeable future as we advance the development of pelareorep and incur research and development, manufacturing, and general and administrative expenses. We do not expect to generate significant revenues unless and until pelareorep receives regulatory approval and becomes commercially viable.

As of March 31, 2026, we had cash and cash equivalents of $5,493. Based on our current operating plan, we expect that our existing cash resources, even when considered together with available capital under our equity distribution arrangements, are sufficient to fund near‑term operating milestones but are not sufficient to fund our planned operations for at least twelve months from the date of issuance of our condensed consolidated financial statements included in this quarterly report. These conditions raise substantial doubt about our ability to continue as a going concern.

Our ability to continue as a going concern depends on our ability to obtain additional financing to fund ongoing operations. Management has plans to raise additional capital, including through the use of our at‑the‑market equity sales agreement and potential strategic collaborations or other financing arrangements, as discussed under “Capital Requirements.” However, there can be no assurance that additional financing will be available when needed, on acceptable terms, or at all. If we are unable to

20

obtain additional funding as required, we may need to reduce or delay research and development activities, scale back operations, or pursue strategic alternatives.

The accompanying condensed consolidated financial statements have been prepared on a going‑concern basis and do not include any adjustments that might result from the outcome of these uncertainties. Such adjustments could be material.

Program Development Updates and Outlook

The following are the development updates and outlook for each of our programs for the three months ended March 31, 2026, through to the date of this quarterly report.

Clinical Trial Program

Second-line metastatic colorectal cancer (“mCRC”)

In late 2025, we filed for Fast Track Designation for pelareorep in combination with bevacizumab and FOLFIRI for the treatment of patients with Kirsten rat sarcoma (“KRAS”)-mutant, microsatellite-stable mCRC in the second-line setting. The application was supported by clinical data demonstrating a 33% objective response rate (“ORR”) for pelareorep-based therapy compared to approximately 10% ORR with standard-of-care1 in this patient population. In addition, pelareorep combination therapy was associated with a median progression-free survival (“PFS”) of 16.6 months, compared to 5.7 months with standard-of-care2, a duration of response of 19.5 months, compared to historical benchmarks of approximately 4–6 months3 in this setting, and a median overall survival of 27 months, compared to 11.2 months with standard-of-care4. The FDA granted our application, awarding Fast Track Designation for this indication in 2026.

Randomized Phase 2 second-line mCRC study

In March 2026, we launched a randomized Phase 2 study evaluating second-line RAS-mutated (which includes KRAS) MSS mCRC patients. Patients will receive either the control arm of bevacizumab (Avastin®) and FOLFIRI or the experimental arm of pelareorep, bevacizumab, and FOLFIRI. The first study site was initiated in early April 2026.

Second-line or later squamous cell carcinoma of the anal canal (“SCAC”)

GOBLET Cohort 4

Pelareorep is being studied in combination with atezolizumab in the rare, but deadly, relapsed, unresectable SCAC indication.

In January 2026, we reported updated clinical data from patients with third-line SCAC. The data showed four of 14 evaluable third-line patients receiving pelareorep and atezolizumab achieved objective responses, resulting in an ORR of approximately 29%. These responses included two complete responses and two partial responses. The median duration of response is approximately 17 months (67 weeks), indicating both depth and durability of clinical benefit in a heavily pretreated population. In historical third-line SCAC studies, objective response rates are typically approximately 10% or less5, with limited durability. In the second-line setting, pelareorep and atezolizumab achieved a 30% ORR, more than doubling the 13.8% ORR that was approved by the FDA for the current standard of care therapy6. We are no longer enrolling patients in Cohort 4 and will continue to monitor patients on the study and provide a final analysis once sufficient data has been collected.

Potential second-line or later SCAC registrational study

We participated in a Type C meeting with the FDA in mid-April of 2026 and aligned on the design of a pivotal study in second-line or later SCAC in the U.S. The final study protocol is being finalized and is expected to be a randomized controlled trial of pelareorep and a checkpoint inhibitor, compared with a control arm, which could be sufficient for accelerated approval and full approval at different points in time within the same study.

First-line metastatic pancreatic ductal adenocarcinoma (“mPDAC”)

GOBLET Cohort 5

In a randomized two-arm cohort, pelareorep is being evaluated in combination with modified FOLFIRINOX with or without atezolizumab to gain greater clarity regarding the contribution of the checkpoint inhibitor to the efficacy achieved in GOBLET Cohort 1. In that cohort, pelareorep combined with gemcitabine/nab-paclitaxel and atezolizumab achieved a 62% ORR in 13 evaluable patients. GOBLET Cohort 5 is supported by the Pancreatic Cancer Action Network (“PanCAN”) Therapeutic Accelerator Award for up to $5 million.

In the first quarter of 2026, we made the determination that we had sufficient patients enrolled in Cohort 5 that would allow us to properly analyze the combinations being tested in the cohort. We expect to present preliminary analysis of the data in the second half of 2026 once survival data has matured sufficiently.

Potential first-line pancreatic cancer registration study

We participated in a Type C meeting with the FDA in the fourth quarter of 2025 and agreed on the key elements of a Phase 3 trial of pelareorep in combination with standard-of-care therapy for the first-line treatment of mPDAC. This trial would evaluate pelareorep and gemcitabine/nab-paclitaxel with or without a checkpoint inhibitor compared to chemotherapy alone. The primary endpoint of the study is overall survival, and PFS and ORR are secondary endpoints. We remain in active discussions with potential partners to supply a checkpoint inhibitor and fund our proposed first-line PDAC study. Until we enter into a transaction agreement with a partner, we do not expect to advance this study on our own and plan to focus our resources on other high-value indications that provide a more efficient path to registration for pelareorep.

Clinical development for the remainder of 2026

In 2026, our clinical objectives will primarily revolve around our randomized second-line mCRC clinical study. We are actively evaluating multiple strategic partnership options and continue to engage with collaborators, academic partners, and other stakeholders to determine the most effective path forward for pelareorep in PDAC and second-line or later SCAC.

Manufacturing and Process Development

While we currently have sufficient drug product supply to support our clinical development program, we continued our activities to expand our production capabilities as we focus on advancing our active drug substance and finished drug product towards registration and commercial readiness. In the first quarter of 2026, we completed analytical testing for the cGMP production run and drug product fill initiated in 2025. We also updated the formal assessment of the drug substance production process and began analytical development activities to support upcoming process characterization in preparation for process performance qualification. We also incurred storage and distribution costs to maintain our product supply. Ongoing bulk manufacturing and expanded filling capabilities are both part of the planned process validation. Process validation is required to ensure that the resulting product meets the specifications and quality standards and will form part of our submission to regulators, including the FDA, for product approval.

In 2026, our manufacturing program will focus on preparatory activities for validation of our drug substance production process, additional drug product manufacture to support the clinical program, and supply distribution for our ongoing and planned studies.

Intellectual Property

At March 31, 2026, we had 138 patents, including 11 U.S. and 7 Canadian patents, and issuances in other jurisdictions. We have an extensive patent portfolio covering pelareorep and formulations that we use in our clinical trial program. We also have patents covering methods for manufacturing pelareorep and screening for susceptibility to pelareorep. These patent rights extend to at least the end of 2031. We are continuing to analyze additional patent protections and have placed an emphasis on patent extension strategy and growing our patent portfolio. In addition, we have submitted new patent applications that we expect to extend certain patent protections and grant new rights into the 2040s.

Financing Activity

During the three months ended March 31, 2026, we sold 7,446,574 common shares pursuant to at-the-market (“ATM”) offering agreements for gross proceeds of $7,861 at an average price of $1.06 per share, resulting in net proceeds of $7,614 after issuance costs of $247 (including commissions of $236).

From April 1, 2026 to May 12, 2026, we sold 2,575,905 common shares pursuant to a Sales Agreement (see “Other Corporate Matters”) for gross proceeds of $2,363 at an average price of $0.92 per share. We received net proceeds of $2,292 after commissions of $71.

Cash Resources

As of March 31, 2026, we had cash and cash equivalents of $5,493 (see “Liquidity and Capital Resources”).

Other Corporate Matters

In October 2025, we filed a Registration Statement on Form F-4 with the U.S. Securities and Exchange Commission (as amended by Amendment No. 1 to Form F-4, as filed on December 5, 2025) that included a management circular, prospectus and other relevant documents related to various proposals contained therein. It included plans to hold a Special Meeting of Shareholders to vote on, among other things, a series of transactions that would change the jurisdiction of Oncolytics from the Province of Alberta in Canada to the State of Nevada in the U.S. (the “Domestication”). On January 15, 2026, all resolutions described in this registration statement were approved by our shareholders. On March 17, 2026, as part of the Domestication process, we changed our jurisdiction of incorporation to the Province of British Columbia in Canada. On March 31, 2026, we completed the Domestication and changed our jurisdiction to the State of Nevada.

On April 6, 2026, we entered into an Open Market Sale Agreement (the “Sales Agreement”) with Jefferies LLC (the “Agent”), pursuant to which we may offer and sell from time to time through or to the agent, acting as agent or principal, shares of our common stock, par value $0.001 per share, having an aggregate offering price of up to $75,000.

Components of Results of Operations

Research and Development Expenses (“R&D”)

Our R&D expenses consist primarily of costs incurred to conduct research and development on pelareorep, including clinical trial expenses, manufacturing and related process development expenses, personnel-related expenses, translational science expenses, and other R&D expense. Clinical trial expenses include regulatory and consulting activities, contract research organization expenses, data management expenses, and other costs associated with our clinical trial program. Manufacturing and related process development expenses include product manufacturing and process development activities. Product manufacturing expenses include third-party direct manufacturing costs, quality control testing, filling, labeling, packaging, and storage costs. Process development expenses include costs associated with studies examining components of our manufacturing

23

and analytical processes and costs associated with planned process validation and related conformity testing. Translational science expenses are intended to expand our intellectual property related to pelareorep and identify potential licensing opportunities arising from our technology base. Personnel-related expenses include salaries and wages, stock-based compensation, and other employee-related expenses.

General and Administrative Expenses (“G&A”)

Our G&A expenses consist primarily of public company-related expenses, personnel-related expenses, intellectual property expenses, office expenses, lease expense and depreciation. Public company-related expenses include investor, media, and public relations, marketing communications, business development, financial advisory activities, legal and accounting fees, corporate insurance, transfer agent costs, and other fees relating to our U.S. and Canadian stock listings (we voluntarily delisted from the Toronto Stock Exchange in August 2025). Personnel-related expenses include salaries and wages, director fees, stock-based compensation, and other employee-related expenses. Intellectual property expenses include legal and filing fees associated with our patent portfolio. Office expenses include administrative costs associated with operating our business.

Results of Operations

Comparison of the three months ended March 31, 2026 and 2025:

Net loss for the three months ended March 31, 2026 was $9,243 compared to $4,711 for the three months ended March 31, 2025.

Research and Development Expenses

Our R&D expenses increased by $1,752 from $2,800 for the three months ended March 31, 2025, to $4,552 for the three months ended March 31, 2026. The following table summarizes our R&D expenses for the three months ended March 31, 2026 and 2025:

						Three months ended March 31
						2026						2025						Change
Clinical trial expenses						$	747					$	370					$	377
Manufacturing and related process development expenses						507						414						93
Personnel-related expenses						3,271						1,981						1,290
All other R&D expenses						27						35						(8)
Total R&D expenses						$	4,552					$	2,800					$	1,752

The increase in our R&D expenses for the three months ended March 31, 2026, was primarily due to the following:

•Increased personnel-related expenses due to increased stock-based compensation expense and increased headcount. The increase in stock-based compensation expense was due to new stock option grants in the second half of 2025 and an adjustment to reclassify options from equity-classified to liability classified as discussed in note 3 of the condensed consolidated financial statements. This increase was partly offset by CEO transition-related activities in the first quarter of 2025.

•Increased clinical trial expenses due to start-up costs for our phase 2 second-line mCRC study launched in the first quarter of 2026 and higher registration program planning-related expenses. Our clinical trial expenses for the three months ended March 31, 2026 included $143 of non-cash stock-based compensation expense for consulting services.

24

General and Administrative Expenses

Our G&A expenses increased by $2,508 from $2,221 for the three months ended March 31, 2025, to $4,729 for the three months ended March 31, 2026. The following table summarizes our G&A expenses for the three months ended March 31, 2026 and 2025:

						Three months ended March 31
						2026						2025						Change
Public company-related expenses						$	3,016					$	1,200					$	1,816
Personnel-related expenses						1,230						737						493
Intellectual property expenses						302						107						195
All other G&A expenses						181						177						4
Total G&A expenses						$	4,729					$	2,221					$	2,508

The increase in our G&A expenses for the three months ended March 31, 2026 was primarily due to the following:

•Increased public company-related expenses due to higher investor relations activities and professional fees related to the Domestication. Our public company-related expenses for the three months ended March 31, 2026 included $587 of non-cash stock-based compensation expense for consulting services.

•Increased personnel-related expenses due to increased stock-based compensation expense as a result of new stock options grants in the second half of 2025.

•Increased intellectual property expenses related to executing our patent extension strategy and new patent applications.

Cash used in operating activities

The increase in net cash used in operating activities reflects higher operating activities and higher non-cash working capital changes in 2026. Overall, net cash used in operating activities for the three months ended March 31, 2026 and 2025 was primarily related to the funding of our research and development activities, including personnel-related expenses, manufacturing and clinical trial costs, and other costs associated with general and administrative expenses.

Net cash used in operating activities for the three months ended March 31, 2026 consisted of a net loss of $9,243 and non-cash working capital changes of $1,181, partially offset by non-cash adjustments of $3,131. Non-cash items primarily included stock-based compensation expense and the value of shares issued for consulting services. Non-cash working capital changes

Capital Requirements

As a clinical‑stage biopharmaceutical company, we have not been profitable since inception and do not expect to generate significant revenues unless and until pelareorep receives regulatory approval and becomes commercially viable. We expect to continue to incur operating losses as we advance pelareorep through clinical development and incur costs associated with manufacturing, intellectual property protection, and operating as a public company. Historically, we have funded our operations primarily through the issuance of equity securities, including public offerings, at‑the‑market equity programs, and the exercise of warrants.

Our near‑term capital requirements are driven primarily by the advancement of our second‑line metastatic colorectal cancer and second‑line or later squamous cell carcinoma of the anal canal programs, as well as ongoing manufacturing readiness activities and general corporate costs. Conducting clinical trials necessary to obtain regulatory approval is costly and time‑consuming, and the timing and cost required to complete such trials are inherently uncertain. As a result, we are unable to predict with certainty the duration or total costs of our research and development programs or when, if ever, we may generate revenues from the commercialization of pelareorep.

As discussed under “Going Concern,” our current cash resources are sufficient to fund near‑term operating milestones but are not sufficient to fund planned operations for at least twelve months from the date of issuance of our condensed consolidated financial statements included in this quarterly report. To support our near‑term liquidity needs, we have access to capital through the Sales Agreement with the Agent, which provides flexibility to raise capital opportunistically and manage our cash resources. We expect to continue to utilize this equity distribution arrangement as appropriate to support ongoing operations; however, there can be no assurance that sufficient capital will be available under this or other arrangements on acceptable terms or at all.

Our future capital requirements beyond the near term will depend on several factors, including the timing, scope, and results of our clinical trials; regulatory interactions and outcomes; the costs associated with manufacturing process validation and supply; potential partnerships or collaborations; and broader market conditions. Although our Board of Directors reviews and approves our annual budget and multi‑year operating plans, actual funding requirements may differ materially from our expectations due to the inherent risks and uncertainties associated with drug development.

To fund our operations beyond the near term, we expect to seek additional capital through the sale of equity securities, strategic collaborations, licensing arrangements, or other financing sources. Additional financings may result in dilution to existing shareholders, and any debt or collaborative financing, if available, may include terms that restrict our operating flexibility or require us to relinquish rights to pelareorep or future revenues. If we are unable to obtain additional financing when required, we may need to reduce or delay certain development activities, pursue strategic alternatives, or take other measures to conserve capital.

For the three months ended March 31, 2026, we raised net cash proceeds of $7,614 from the issuance of 7,446,574 common shares through our ATM offering agreement.

We are not subject to externally imposed capital requirements, and there have been no changes in how we define or manage our capital in 2026.

Contractual Obligations and Commitments

As of March 31, 2026, our contractual obligations are comprised primarily of our accounts payable, accrued liabilities and operating lease obligations. In addition, we are committed to payments of approximately $350 for activities mainly related to our contract manufacturing program, which are expected to occur over the next one year. We are able to cancel most of these agreements with notice. The ultimate amount and timing of these payments are subject to changes in our research and development plan.

As of March 31, 2026, we had not entered into any off-balance sheet arrangements.
