Current report

We could fail to maintain the listing of our Class A common stock on the Nasdaq Stock Market LLC (“Nasdaq”), which could seriously harm the liquidity of our shares and our ability to raise capital or complete a strategic transaction.

Current report

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.

Current report

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 report

Our Proteus TM platform (“Proteus”), which was originally anticipated to be launched at the end of 2026, is now estimated to be commercially available in the second quarter of 2027. If Proteus is not launched within our updated time frame, or is delivered without the applications and capabilities our customers are seeking, it could materially impact any potential of long-term financial success and our market credibility.

Current report

Since November 2024, we have provided overall market periodic updates on our Proteus platform development, including overall development status, initial views on capabilities and output, and indications or potential customer applications, as well as an anticipated commercial launch date. On August 13, 2026, we announced the anticipated launch date of Proteus had moved from the end of 2026 to the second quarter of 2027. Development of a new product platform is inherently difficult, and can often experience delays resulting from hardware integration, inability to develop desired customer applications for the commercial launch, unforeseen regulatory issues, hardware supplier challenges or a variety of other challenges impacting a commercial launch, which we have experienced. If our Proteus platform experiences a further commercial launch delay due to these reasons or other impacts on our development program, it could materially impact any long-term financial success of the Company, and further, materially impact and damage our market credibility, negatively impacting commercial success and company valuation.
