Yes. The report is your document, and ISO 27001 places no restriction on sharing it.
Start with what the person asking needs. A customer's security team doing due diligence wants to know three things: that your ISMS is audited, that findings are handled, and that nothing serious is open. A one-page summary answers all three: the audit date and auditor, the scope, the number of findings by grade, and the status of each.
The full report is a detailed list of your weak points, with evidence, system names and sometimes names of staff. If a customer insists on it, share it under NDA and attach the corrective action log, so every finding is read next to its fix. Some companies show it only in a screen-share session and never send the file.
Investors usually need less. A line in the data room confirming the audit, its date and that no majors are open is often enough.
Once you are certified, the certificate and its scope statement answer most of these requests, and the internal audit report rarely comes up.
