TORONTO and DALLAS, March 5, 2025 /PRNewswire/ - Perimeter Medical Imaging AI, Inc. (TSXV: PINK) (OTCQX: PYNKF) ("Perimeter" or the "Company"), a commercial-stage medical technology company, is pleased to announce that detailed results from the pivotal trial evaluating the use of its next-generation B-Series OCT with ImgAssist AI 2.0 ("Perimeter B-Series") during breast-conserving surgeries ("BCS") will be presented during the scientific session of the 26^th Annual Meeting of the American Society of Breast Surgeons ("ASBrS") taking place in Las Vegas, NV, April 30-May 4, 2025.

ASBrS is the primary leadership organization for general surgeons who treat patients with breast disease and is committed to continually improving the practice of breast surgery by serving as an advocate for surgeons who seek excellence in the care of breast patients.

The detailed results of the Perimeter B-Series pivotal trial are subject to an embargo policy, pursuant to which all scientific abstracts accepted for oral or poster presentations during the ASBrS 26th Annual Meeting, press releases, and the Society's Official Proceedings are embargoed until 1:00 pm PST on May 1, 2025. The full abstract will be published by the Annals of Surgical Oncology and released following the oral presentation by Dr. Alastair Thompson, the trial's Primary Principal Investigator, Surgeon and Professor, Section Chief of Breast Surgery, Olga Keith Wiess Chair of Surgery at Baylor College of Medicine, Breast Cancer Program Leader at the Dan L Duncan Comprehensive Cancer Center. The Annals of Surgical Oncology is one of the leading journals in oncology and surgery, and features original articles on the latest advances in oncology for surgeons from all specialties.

"It is a great honor to be selected by the ASBrS to present the detailed results of our pivotal trial for the first time at its prestigious annual meeting, and we are pleased this comes as we continue to work toward obtaining regulatory approval to market our next-generation, AI-enabled OCT system in the United States," said Perimeter's Chief Executive Officer, Adrian Mendes. "Adding an AI assistant will help surgeons more easily utilize our ground-breaking wide-field OCT technology, which provides high-resolution clarity to visualize margins in real-time in the operating room. We believe increasing breast cancer surgeon awareness of this important innovation through participation in important forums like ASBrS 2025 will go a long way towards advancing the technology's future adoption."

In November 2024, Perimeter reported positive topline results from the pivotal study designed to support the Company's planned U.S. Food and Drug Administration ("FDA") premarket approval ("PMA") submission to market the Perimeter B-Series for use during BCS in the United States. The Company plans to submit its FDA PMA for the Perimeter B-Series in early 2025.
