Aclarion has developed a software application called NOCISCAN®. The product uses the existing MRS capabilities of many commercially available scanners to non-invasively analyze the chemical makeup of intervertebral discs in the spine. The software post-processes the MRS exam data and detects the presence of chemical biomarkers that Aclarion, in conjunction with spine researchers at UCSF, have demonstrated to be associated with degenerative pain and structural integrity of the lumbar discs. After processing the MRS exam data, Aclarion sends the ordering clinician a report that details how to interpret the results of the MRS exam. We believe these results help clinicians make faster and more informed decisions about which lumbar discs are painful, and which are not.
· NOCIGRAM® further processes the NOCICALC results into individual NOCISCORES, on a 0-10 scale, that represent the different relative levels of degenerative pain biomarkers the various discs examined in the patient. High/low NOCISCORE ranges are also correlated to painful (indicated as “NOCI+” result) versus non-painful (indicated as a “NOCI-result). The NOCISCORE scale was developed according to a reference PD TEST that was used as a standard control in a peer reviewed clinical development trial for our technology. The post-processed MRS results are shown in an intuitive NOCIGRAM report with reference to certain MRI images of the related patient’s lumbar spine. The NOCIGRAM report is provided to the physician to aide in the physician’s diagnosis and treatment planning.

In 2024, we launched our first software product, HeartRisk™. HeartRisk™ is a cardiovascular disease risk intelligence platform that combines insights from HIPAA-compliant anonymized and aggregated clinical cardiovascular data obtained through our Epi+Gen CHD™ and PrecisionCHD™ clinical blood tests, with industry and geographic data to enable real-time population-level cardiovascular disease (“CVD”) risk insights. These insights are customized for the stakeholder implementing our clinical solutions. 8 Clinicians’ Current Approach to Cardiovascular Disease Currently, a patient’s risk for CVD is generally assessed using two common lipid-based clinical tests known as Framingham Risk Score (FRS) and ASCVD Pooled Cohort Equation (PCE).
We believe that the Epi+Gen CHD™ test can benefit numerous healthcare stakeholders. For instance, we believe that this test will enable clinicians to identify patients at-risk in the near-term for CHD-related events, including a heart attack, and utilize actionable insights from this test to provide more personalized care for their patients to help prevent the event and improve outcomes. These actionable insights are conveyed via our provider-facing Actionable Clinical Intelligence™ platform, which maps a patient’s unique biomarker profile and other information onto pathways and modifiable drivers of coronary heart disease. In addition to clinicians, we believe that this test can enable healthcare organizations and payors to reduce the cost of care, and employers to understand and better manage business risks including healthcare costs.

(c) The NOCISCAN Post-Processor Suite: This comprises the products that Aclarion currently markets and sells. The post-processor technology requires MRS exam data acquired only according to Aclarion’s proprietary MRS exam protocols described in (a) above. The NOCISCAN Post-Processor Suite comprises of two software products that interact with each other: · NOCICALC® receives the raw un-processed NOCISCAN MRS exam data and post-processes that raw data into final spectra, and performs various degenerative pain biomarker calculations from those spectra, for each disc examined. NOCICALC is Registered as a Class I Medical Device with the FDA.
In the United States, the NOCISCAN product suite is only partially regulated as a medical device by the FDA. The NOCICALC product is considered a Class I “exempt” medical device and is registered as such with the FDA under product Classification “Calculator/Data Processing Module, for Clinical Use,” Product Code “JQP,” Regulation Number 862.2100, and Registration Number 3015426626. The process to determine whether a product can be considered a Class I “exempt” medical device consists of self-determining whether the product is adequately described by one of the existing categories classified by the FDA. In conjunction with our regulatory consultants, we determined that the product Classification “Calculator/Data Processing Module, for Clinical Use,” adequately described our NOCICALC product.

Behind the comparison

Sources and methodology

Price return uses split-adjusted daily closes and excludes dividends. Both stocks start on the first shared trading day within the selected window. Unavailable metrics leave gaps.

Financials use SEC canonical statements available by the displayed cutoff, retaining each company's fiscal period end. Annual and quarterly amounts are shown separately. P/E is unavailable when earnings do not support a positive ratio.

Business overlap uses industry tags from annual filings released in 2025. Each core activity receives full weight; each material activity receives one quarter of that weight. Rarer industries carry more weight. We sum the smaller exposure for each shared activity and divide it by the sum of the larger exposure for every activity in either company. This measures business overlap, rather than price correlation or expected returns.

Search eligibility requires distinct issuers, a shared core category and at least 20% weighted overlap, supported by industry or sector evidence and specific business activities. Broad classifications require stronger overlap within the same sector. Comparisons also need at least 252 shared price observations within two years, recent trading and a common sourced revenue or net-income trend. Missing P/E or gross margin alone does not exclude a comparison. The eligibility snapshot refreshes daily. Related comparisons use a separate, stricter peer rule; their ten-peer discovery limit does not limit search eligibility. Other stock pairs remain available in the comparison tool.
