Risk factors and legal proceedings

The risks Quantum Computing Inc. names in Item 1A of its 10-K filed Mar 2, 2026: 46 risks under these headings, as written.⁵

• Risks Related to Our Financial Condition and Status as an Early-Stage Company
• We are in our early stages and have a limited operating history, which makes it difficult to forecast the future results of our operations.
• We have a history of operating losses and expect to incur significant expenses and continuing losses for the foreseeable future.
• We have a history of accumulated deficits, recurring losses and negative cash flows from operating activities. We may be unable to achieve or sustain profitability or continue operations as planned.
• We may not be able to scale our business quickly enough to meet customer and market demand, which could adversely affect our financial condition and results of operations or cause us to fail to execute on our business strategies.
• Even if the market in which we compete achieves its anticipated growth levels, our business could fail to grow at similar rates, if at all.
• We may not manage growth effectively.
• We will require a significant amount of cash for expenditures as we invest in ongoing research and development and business operations and may need additional capital sooner than planned to pursue our business objectives and respond to business opportunities, challenges or unforeseen circumstances, and we cannot be sure that additional financing will be available. If we are unable to raise additional funding when needed, we may be required to delay, limit or substantially reduce our development efforts.
• Failure to identify errors in the quantitative models we utilize to manage our business could adversely impact product performance and client relationships.
• Our ability to use net operating loss carryforwards and other tax attributes may be limited in connection with the QPhoton Merger or other ownership changes.
• Risks Related to Our Business and Industry
• We have not produced any of our products at volume and we face significant barriers in our attempts to develop and manufacture our products, including the need to invent and develop new technology. If we cannot successfully overcome those barriers, our business will be negatively impacted and could fail.

Legal proceedings

Except as listed below, there is no action, suit, or proceeding by any court, public board, government agency, self-regulatory organization or body pending or, to the knowledge of the executive officers of the Company or our subsidiaries, threatened against or affecting the Company, our common stock, our subsidiaries, or the Company’s or its subsidiaries’ officers or directors in their capacities as such, in which an adverse decision could have a material adverse effect on the Company.

BV Advisory Partners, LLC Proceedings

BV Advisory v. QCi Appraisal Action
