Current report
We rely on certain contract manufacturers to manufacture and supply our instruments, components of our instruments, and certain components of our consumable offerings. If these manufacturers should fail or not perform satisfactorily, or for economic or other reasons choose to end business with us, our ability to commercialize and supply our instruments and consumable offerings would be adversely affected.
Current report
We rely on certain contract manufacturers to manufacture and supply our instruments, components of our instruments, and certain components of our consumable offerings. Since most of our contracts with these manufacturers do not commit them to carry inventory or make available any particular quantities, these manufacturers may give other customers’ needs higher priority than ours, and we may not be able to obtain adequate supplies in a timely manner or on commercially reasonable terms. Also, if these manufacturers are unable to obtain critical components used in our instruments or supply our instruments on the timelines we require, our business and commercialization efforts would be harmed. Further, any strategic decision to slow, pause, or stop any core supply based on assumptions of adequate safety stock that subsequently proves to be an incorrect estimate of supply needs could result in a supply disruption based on the ability to ramp up or slowness in ramp down processes.
Current report
In the event it becomes necessary to utilize different contract manufacturers for our products or components of our products, we would experience additional costs, delays and difficulties in doing so as a result of identifying and entering into an agreement with a new manufacturer as well as preparing such new manufacturer to meet the logistical requirements associated with manufacturing our instruments and consumable offerings, and our business would suffer. In addition, if our products are authorized for use by the FDA as medical devices, we will need to contract with FDA-registered device establishments that are able to comply with current Good Manufacturing Practice requirements that are set forth in the QSR, unless explicitly exempted by regulation.
Current report
Certain of the components and consumables used in our instruments and consumable offerings are sourced from a limited number, or sole source suppliers. If we were to lose such a supplier, there can be no assurance that we will be able to identify or enter into an agreement with an alternative supplier on a timely basis on acceptable terms, if at all. An interruption in our ability to sell and deliver instruments or consumable offerings to customers could occur if we encounter delays or difficulties in securing these components or consumables, or if the quality of the components or consumables supplied do not meet specifications, or if we cannot then obtain an acceptable substitute. In the past, our suppliers have been impacted by global pandemics and epidemics, such as the COVID pandemic, and we have experienced supply delays for critical hardware and instrumentation as a result. If any of these events occur, our business, results of operations, financial condition and prospects could be harmed.
Current report
As the development and use of artificial intelligence (“AI”) has ramped up globally, overall supply chains have become constrained, potentially impacting our supply chain and ability to manufacture our products in a timely fashion to satisfy customer demand. Constraints in supply chains as a result of AI can impact all areas of the underlying supply chain, well beyond access to specialized semiconductors, memory or related parts, but continuing down to all underlying raw materials. Finally, access to specialized semiconductors and related AI components, whether due to geopolitical tensions, export controls, manufacturing constraints, natural disasters, or supplier-specific issues, could materially impair our ability to manufacture our products or meet customer demand.

Previous wording
Nasdaq has established continued listing requirements, including a requirement to maintain a minimum closing bid price of at least $1.00 per share. On July 23, 2026, we received written notice from Nasdaq notifying us that, because the closing bid price for our Class A common stock has fallen below $1.00 per share for 30 consecutive business days, we no longer meet the minimum bid price requirement for continued inclusion on The Nasdaq Global Market pursuant to Nasdaq Listing Rule 5450(a)(1) (the “Bid Price Requirement”). In accordance with Nasdaq Listing Rule 5810(c)(3)(A), we have been provided an initial period of 180 calendar days, or until January 19, 2027 (the “Compliance Date”), to regain compliance with the Bid Price Requirement. To regain compliance, the closing bid price of our Class A common stock must be at least $1.00 per share for a minimum of 10 consecutive business days during this 180-calendar day period. If we do not regain compliance with the Bid Price Requirement by the Compliance Date, we may be eligible for an additional 180-calendar day compliance period. To qualify, we would need to transfer the listing of our Class A common stock to The Nasdaq Capital Market and meet the continued listing requirement for the market value of publicly held shares and all other initial listing standards, with the exception of the Bid Price Requirement. To effect such a transfer, we would also need to pay an application fee to Nasdaq and would need to provide written notice to the Staff of our intention to cure the deficiency during the additional compliance period by effecting a reverse stock split if necessary.

Previous wording
There can be no assurance that we will be able to regain compliance with the Bid Price Requirement or maintain compliance with other Nasdaq requirements in the future. If we are not able to regain and maintain compliance with Nasdaq requirements, our Class A common stock may be delisted from Nasdaq, which could have a material adverse effect on us and our stockholders, including by negatively impacting our trading price, reducing the liquidity of our shares and having a material adverse effect on our ability to raise capital or complete a strategic transaction.
Current wording
Despite regaining compliance on October 13, 2026, there can be no assurance that we will be able to maintain compliance with the Bid Price Requirement or maintain compliance with other Nasdaq requirements in the future.
