Current report
We are evaluating and exploring a variety of strategic alternatives focused on maximizing stockholder value, including, but not limited to, an acquisition, merger, reverse merger, other business combination, sales of assets or other strategic transactions. Our ability to successfully execute on a strategic alternative is dependent on a number of factors and we may not be able to execute upon a transaction or other strategic alternative upon favorable terms within an advantageous timeframe and recognize significant value for our assets, if at all. Additionally, the negotiation and consummation of a transaction or other strategic alternative may be costly and time-consuming. Any executed strategic alternative may not maximize or even enhance stockholder value, could result in total costs and expenses that are greater than expected, could make it more difficult to attract and retain qualified personnel and may disrupt our operations, each of which could have a material adverse effect on our business.
Current report
The market price of our common stock may reflect a market assumption that a strategic alternative will occur, and a failure to complete a strategic alternative could result in negative investor perceptions and could cause a decline in the market price of our common stock, which could adversely affect our ability to access the equity and financial markets, as well as our ability to explore and enter into different strategic alternatives. There can be no certainty that any strategic alternative will be completed, be on attractive terms, enhance stockholder value or deliver the anticipated benefits, and successful integration or execution of the strategic alternatives will be subject to additional risks.

Previous report
Our auditor’s report on our consolidated financial statements contains an explanatory paragraph regarding our ability to continue as a going concern.
Previous report
The shutdown of the U.S. federal government may adversely affect our business.
Previous report
A prolonged or recurring shutdown of the U.S. federal government may adversely affect our business operations and regulatory compliance. During such shutdowns, while the SEC’s EDGAR system remains operational, the unavailability of SEC staff to review filings, issue comments, or declare registration statements effective may delay our ability to complete public offerings, respond to comment letters, or obtain timely regulatory approvals. These delays could impact our access to capital markets, hinder strategic transactions, and create uncertainty around our disclosure obligations. Additionally, the lack of interpretive guidance or exemptive relief during a shutdown may increase legal and compliance risks. We continue to monitor developments and adjust our regulatory strategies accordingly, but there can be no assurance that future shutdowns will not materially affect our operations or financial condition.
Previous report
Currently, federal agencies in the United States are operating under a federal government shutdown due to the expiration of the continuing resolution that expired on September 30, 2025. The duration of the current government shutdown is unknown. In addition, the current U.S. administration is focused on reducing costs of the federal government generally, including significantly reducing the number of government employees. Without appropriation of additional funding to federal agencies, our business operations related to our product development activities for the U.S. market could be impacted. The ability of the FDA to review and approve new products can be affected by a variety of factors, including government budget and funding levels, the ability to hire and retain key personnel and accept the payment of user fees, and statutory, regulatory and policy changes. Average review times at the agency have fluctuated in recent years as a result. In addition, government funding of the SEC and other government agencies on which our operations may rely is subject to the political process, which is inherently fluid and unpredictable.
Previous report
Our business depends on timely interactions with the FDA, including the review of regulatory submissions, scheduling of formal meetings, and oversight of clinical trials. Disruptions at the FDA and other federal agencies, including substantial leadership departures, personnel cuts, policy changes and those related to the federal government shutdown, may result in reduced staffing or suspension of non-essential FDA operations, which could delay or cancel meetings with the FDA, including our upcoming meetings with the FDA for planned clinical trials in patients with mPDAC and retinoblastoma, hinder regulatory guidance, cause delays in the implementation or enforcement of regulatory requirements in a timely fashion or at all, and postpone the review of IND applications, New Drug Applications (NDAs), and Biologics License Applications (BLAs). These disruptions may also affect the initiation, conduct, and monitoring of clinical trials, particularly those requiring FDA authorization or ongoing regulatory engagement. Interruptions in FDA activities could materially delay our development timelines, increase operational costs, and adversely impact our ability to complete our ongoing and planned clinical trials and to advance product candidates toward approval and commercialization. Any such delays or uncertainties may have a significant negative effect on our business, financial condition, and results of operations.
Previous report
Certain of our clinical trials are dependent on federal grant funding. A lapse in appropriations resulting in a government shutdown could materially disrupt the timing and availability of these funds. During such shutdowns, federal agencies may suspend the processing of new grant applications, delay reimbursements, or pause disbursements for existing awards. These interruptions could adversely affect our ability to commence enrollment for the third cohort of our Phase 1b/2a randomized, double-blinded, placebo-controlled clinical trial of SYN-004 (ribaxamase) in allogeneic hematopoietic cell transplant (“HCT”) recipients for the prevention of acute graft-versus-host-disease because we cannot fund the SYN-004 development program unless we receive grant funding. If federal funding continues to be delayed, reduced or canceled, we may need to seek alternative sources of financing, scale back research efforts, or defer planned initiatives, any of which could have a material adverse effect on our financial condition and results of operations.

Previous wording
Our consolidated unaudited financial statements as of September 30, 2025 have been prepared under the assumption that we will continue as a going concern for the next twelve months. Our management concluded that our recurring losses from operations and the fact that as of September 30, 2025 we have an accumulated deficit of approximately $356.7 and working capital of $(1.1 million) raise substantial doubt about our ability to continue as a going concern for the next twelve months after issuance of our financial statements. In addition, in connection with the filing of our 2024 Form 10-K our independent registered public accounting firm issued a report that included an explanatory paragraph referring to our recurring losses from operations (anticipated continued losses in the future) and net capital deficiency that, as of the date of such report, raised substantial doubt in our ability to continue as a going concern without additional capital becoming available. As of September 30, 2025, we had cash and cash equivalents of approximately $7.5 million and as of early November 2025, we had cash and cash equivalents of $15.5 million. At December 31, 2024, we had an accumulated deficit of $335 million and working capital of $8.7 million. As of December 31, 2024, we had cash and cash equivalents of approximately $11.6 million consisting of cash and investments in highly liquid U.S. money market funds. Our ability to continue as a going concern is dependent upon our ability to obtain additional equity or debt financing, attain further operating efficiencies, reduce expenditures, and, ultimately, to generate revenue. Our consolidated unaudited financial statements as of September 30, 2025 do not include any adjustments that might result from the outcome of this uncertainty. Based upon the Company’s current business plans, we expect that our current cash will be able to fund operations into the first quarter of 2027.
Current wording
Our consolidated unaudited financial statements as of March 31, 2026 have been prepared under the assumption that we will continue as a going concern for the next twelve months. Our management concluded that our recurring losses from operations and the fact that we will require additional financing as we continue to execute our business strategy, including the need for additional funds for the commencement of our planned clinical trials, raise substantial doubt about our ability to continue as a going concern for the next twelve months after issuance of our financial statements. In addition, in connection with the filing of our 2025 Form 10-K our independent registered public accounting firm issued a report that included an explanatory paragraph referring to our recurring losses from operations (anticipated continued losses in the future) and net capital deficiency that, as of the date of such report, raised substantial doubt in our ability to continue as a going concern without additional capital becoming available. As of March, 31, 2026 we had cash and cash equivalents of approximately $14.4 million and as of early May 2026, we had cash and cash equivalents of $13.1 million. At December 31, 2025, we had an accumulated deficit of $358.7 million and working capital of $7.5 million. As of December 31, 2025, we had cash and cash equivalents of approximately $13.1 million consisting of cash and investments in highly liquid U.S. money market funds. Our ability to continue as a going concern is dependent upon our ability to obtain additional equity or debt financing, attain further operating efficiencies, reduce expenditures and, ultimately, to generate revenue. Our consolidated unaudited financial statements as of March 31, 2026 do not include any adjustments that might result from the outcome of this uncertainty. Based upon the Company’s current business plans, we expect that our current cash will be able to fund operations into the first quarter of 2027.
Previous wording
During the nine months ended September 30, 2025, our operating activities used net cash of approximately $13.8 million and our cash and cash equivalents were approximately $7.5 million as of September 30, 2025. With the exception of the three months ended June 30, 2010 and the three months ended December 31, 2017, we have experienced significant losses since inception and have a significant accumulated deficit. As of September 30, 2025, our accumulated deficit totaled approximately $356.7 million on a consolidated basis. Pursuant to the VCN Purchase Agreement, we have agreed to use reasonable efforts to commercialize VCN-01 and we agreed as a post- closing covenant to commit to fund VCN’s research and development programs, including but not limited to VCN-01 PDAC phase 2 clinical trial, VCN-01 retinoblastoma trial and necessary general and administrative expenses within a budgetary plan of approximately $27. 8 million over three years. If we are required to make the $5 million milestone payment to Grifols, it will significantly deplete our cash and cash equivalents, which could materially and adversely affect our liquidity and limit our ability to fund operations or meet other financial obligations. We expect to incur additional operating losses in the future and therefore expect our cumulative losses to increase. With the exception of the quarter ended June 30, 2010, and limited laboratory revenues from Adeona Clinical Laboratory, which we sold in March 2012, we have generated very minimal revenues. We do not expect to derive revenue from any source in the near future until we or our potential partners successfully commercialize our products. We expect our expenses to increase in connection with our anticipated activities, particularly as we continue research and development, initiate and conduct clinical trials, and seek marketing approval for our product candidates. Until such time as we receive approval from the FDA and other regulatory authorities for our product candidates, we will not be permitted to sell our products and therefore will not have product revenues from the sale of products. For the foreseeable future we will have to fund all of our operations and capital expenditures from equity and debt offerings, cash on hand, licensing and collaboration fees and grants, if any.
Current wording
During the three months ended March 31, 2026, our operating activities used net cash of approximately $2.5 million and our cash and cash equivalents were approximately $14.4 million as of March 31, 2026. With the exception of the three months ended June 30, 2010 and the three months ended December 31, 2017, we have experienced significant losses since inception and have a significant accumulated deficit. As of March 31, 2026, our accumulated deficit totaled approximately $360.7 million on a consolidated basis. Pursuant to the Purchase Agreement entered into in connection with the Acquisition, we have agreed to use reasonable efforts to commercialize VCN-01. Additionally, pursuant to the Purchase Agreement, we agreed to pay up to $70.2 million in contingent consideration upon the achievement of certain milestones, including regulatory filings, of which to date $7.3 million has been paid and an additional $5.0 million has been earned but deferred pending ongoing discussion with Grifols. If we are required to make the deferred $5.0 million milestone payment to Grifols, it will significantly deplete our cash and cash equivalents, which could materially and adversely affect our liquidity and limit our ability to fund operations or meet other financial obligations. We expect to incur additional operating losses in the future and therefore expect our cumulative losses to increase. With the exception of the quarter ended June 30, 2010, and limited laboratory revenues from Adeona Clinical Laboratory, which we sold in March 2012, we have generated very minimal revenues. We do not expect to derive revenue from any source in the near future until we or our potential partners successfully commercialize our products. We expect our expenses to increase in connection with our anticipated activities, particularly as we continue research and development, initiate and conduct clinical trials, and seek marketing approval for our product candidates. Until such time as we receive approval from the FDA and other regulatory authorities for our product candidates, we will not be permitted to sell our products and therefore will not have product revenues from the sale of products. For the foreseeable future we will have to fund all of our operations and capital expenditures from equity and debt offerings, cash on hand, licensing and collaboration fees and grants, if any.
Previous wording
We will need to raise additional capital to fund our operations and meet our current timelines and we cannot be certain that funding will be available on acceptable terms on a timely basis, or at all. The amount of government funding available for grants is dependent upon governmental budgets over which we have no control and which change with new administrations. Based on our current plans, we expect that our current cash will be able to fund operations into the first quarter of 2027 but will not be sufficient to fund our operations for the next twelve months and will only be sufficient to cover overhead costs, close out of the VIRAGE Phase 2b clinical trial; exploratory VCN-01 manufacturing scale-up activities, regulatory interactions regarding proposed VCN-01 clinical trials in PDAC and retinoblastoma, preclinical studies supporting VCN-01 and VCN-12, the first candidate from our VCN-X discovery program. The cash is also sufficient to fund our committed obligations under the terms of the VCN Purchase Agreement related to the Acquisition, but may not be sufficient for additional trials of VCN-01, SYN-020 or SYN-004, or to complete the last cohort of the Phase 1a/2a clinical trial of SYN-004, which are expected to require significant cash expenditures. In addition, based on the significant anticipated cost of a Phase 3 clinical program in a broad indication for SYN-004, we expect it will not be feasible for us to initiate and complete this trial at this time without a partner given the capital constraints tied to our current market cap and share price. We intend to focus our capital on our VCN-01 clinical trials and do not intend to provide further funding for our development of SYN-004 internally but intend to out-license or partner further development of SYN-004. Further development of VCN’s product candidates will require additional funding. To the extent that we raise additional funds by issuing equity securities, our stockholders may experience significant dilution. Any debt financing, if available, may involve restrictive covenants that may impact our ability to conduct our business and also have a dilutive effect on our stockholders. A failure otherwise to secure additional funds when needed in the future whether through an equity or debt financing or a sufficient amount of capital without a strategic partnership could result in us being unable to complete planned preclinical and clinical trials or obtain approval of our product candidates from the FDA and other regulatory authorities. In addition, we could be forced to delay, discontinue or curtail product development, forgo sales and marketing efforts, and forgo licensing in attractive business opportunities, cease operations, liquidate our assets or reorganize the Company, or a combination of the foregoing. Our ability to raise capital through the sale of securities may be limited by the rules of the SEC and NYSE American that place limits on the number and dollar amount of securities …

Based on our current plans, we expect that our current cash will be sufficient to fund operations into the first quarter of 2027 and will only be sufficient to cover overhead costs, commence a proposed Phase 2a study in metastatic PDAC patients evaluating more frequent VCN-01 dosing for a longer period, exploratory VCN-01 manufacturing scale-up activities, regulatory interactions regarding a proposed pivotal clinical trial of VCN-01 in retinoblastoma, and limited preclinical studies supporting VCN-01 and VCN-12, the first candidate from our VCN-X discovery program. We believe our cash will also be sufficient to fund our committed obligations under the terms of the Purchase Agreement related to the Acquisition, but may not be sufficient for additional trials of VCN-01 (other than the planned Phase 2a study evaluating more frequent VCN-01 dosing for a longer period), or SYN-004, or to complete the last cohort of the Phase 1a/2a clinical trial of SYN-004, which are expected to require significant cash expenditures.
