Filing Released Lang Actions
REPORT OF FOREIGN PRIVATE ISSUER
Regulatory Filings Classification · 95% confidence The document is a Form 6-K, which is a report of a foreign private issuer filed pursuant to SEC rules 13a-16 or 15d-16 under the Securities Exchange Act of 1934. It contains a press release announcement regarding a peer-reviewed study published by the company, NewcelX Ltd., but no financial statements or detailed financial disclosures. The length of the document is short (2007 characters), and it mainly serves to announce the press release and contain the signature of the CEO. Given these characteristics, it is not an annual or interim report, nor a full audit or earnings release. It does not match categories like AGM, call transcripts, or capital updates. The document also does not contain executive compensation details or governance data. It is primarily a regulatory filing announcing a material event. Therefore, the appropriate classification is Regulatory Filings (RNS), with a high confidence as this is a typical use of Form 6-K filings.

CURRENT REPORT
Proxy Solicitation & Information Statement Classification · 85% confidence The document is a Form 6-K current report by a foreign private issuer that attaches the Notice of Meeting and Proxy Card for the Annual General Shareholders’ Meeting. These materials are sent to shareholders to provide information and request their votes for the AGM. This fits the definition of Proxy Solicitation & Information Statement (PSI).

REPORT OF FOREIGN PRIVATE ISSUER
Regulatory Filings Classification · 87% confidence The document is a Form 6-K “Report of Foreign Private Issuer” filed under the Securities Exchange Act of 1934. It furnishes a press release as Exhibit 99.1 and contains no standalone financial statements or substantive management discussion. This is a general regulatory submission by a foreign issuer rather than a full report (10-K, IR, etc.) or a specialized category (earnings release, M&A, dividend, etc.). It therefore falls into the generic Regulatory Filings (RNS) category.

6-K - NewcelX Ltd. (0001783036) (Filer)
Regulatory Filings Classification · 95% confidence The document is a Form 6-K, which is a report of a foreign private issuer filed with the SEC. It contains a press release titled 'NewcelX Reports Financial Results for 2025 and Provides Shareholders with Update on Accelerated Development of Type 1 Diabetes Treatment in Collaboration with Eledon Pharmaceuticals in 2026.' The document length is 2057 characters, which is relatively short and primarily serves to furnish a press release rather than the full financial report itself. The document does not contain detailed financial statements or substantive financial data but rather an announcement of financial results and updates. According to the 'MENU VS MEAL' rule, such a document is best classified as a Regulatory Filing (RNS) because it is a regulatory announcement furnishing a press release and not the full annual or interim report itself.

6-K - NewcelX Ltd. (0001783036) (Filer)
Regulatory Filings Classification · 95% confidence The document is a Form 6-K, which is a report of a foreign private issuer filed with the SEC. It contains a press release and an investor presentation as exhibits. The document length is 2285 characters, which is relatively short and mainly announces the availability of these materials rather than containing detailed financial data or full reports. The text states that the investor presentation is made available on the company's website and the press release is furnished as an exhibit. There is no substantive financial data or detailed report content within this filing itself. According to the rules, such a filing that primarily announces or furnishes materials without containing the full report or detailed financial statements should be classified as a Regulatory Filing (RNS).

6-K - NewcelX Ltd. (0001783036) (Filer)
Capital/Financing Update Classification · 95% confidence The document is a Form 6-K filed by a foreign private issuer, NewcelX Ltd., with the SEC. It reports a private placement financing transaction including details of securities purchase agreements, share issuance, and warrants. The document is not an annual or quarterly report, nor an earnings release or management discussion. It is a regulatory filing reporting a capital raising event but does not itself constitute a full capital/financing update report. The document is about a financing transaction and related agreements, which fits best under Capital/Financing Update (CAP). The document length is 7477 characters, sufficient to contain substantive details of the financing. Therefore, the classification is CAP with high confidence.
