On October 31, 2018, the FDA granted the Company’s Breakthrough Device designation request (Q181785) for the QT Breast Scanner. Unlike traditional breast imaging modalities, the QT Breast Scanner has no radiation, no injections, and no compression, potentially offering new opportunities for earlier and more frequent screening for young women at high risk for breast cancer who have no available FDA-cleared screening options. The Company has the following regulatory clearances:

• “The QT Breast Scanner is for use as an ultrasonic imaging system to provide reflection-mode and transmission-mode images of a patient’s breast. The QT Breast Scanner software also calculates the breast fibroglandular volume and total breast volume. The device is not intended to be used as a replacement for screening mammography”—FDA 510k K162372 and K220933

• “The QT Breast Scanner Model 2000A satisfies the requirements of the Certification Mark of the ECM [CE Mark Certification of the European Union]—No. 0P210730.QTUTQ02”

The Company has initiated engagement with the FDA to determine the most appropriate regulatory pathway for its premarket submission and to align on the clinical studies necessary to support such submission. The regulatory review process is inherently iterative, and the FDA may provide additional feedback requiring modifications or further evidence in response to the Company's initial submission. There can be no assurance that the Company will obtain the necessary regulatory clearances or approvals in a timely or cost-effective manner, or at all. The process of seeking FDA clearance or approval is resource-intensive, time-consuming, and subject to significant uncertainty. Delays, unexpected costs, or failure to obtain such regulatory authorizations could materially and adversely affect the Company's ability to commercialize its technology and generate revenue. Furthermore, even if regulatory clearance or approval is obtained, the Company’s products will remain subject to extensive post-market regulatory requirements, including compliance with quality system regulations, post-market surveillance, and reporting obligations. Any failure to comply with these requirements, or the identification of previously unknown issues related to the approved product, manufacturing processes, or manufacturers, could result in administrative or judicial enforcement actions by regulatory authorities, including but not limited to warning letters, fines, injunctions, product
