You generally do not need to send an unsolicited grade update the moment results appear unless the firm requests updated transcripts or the new grades materially change your academic profile.

Application processes differ, so use the recruiter or portal instructions as the source of truth. Some firms collect transcripts at a later stage rather than at application.

If the new semester materially improves a weak GPA or includes a prerequisite the recruiter asked about, a concise update can be reasonable.

Keep the message factual: state that new official grades are available and ask whether they would like an updated transcript rather than sending repeated documents without context. Do not frame the update as an attempt to reopen the application; it is simply new academic information that recruiting can use if relevant.

I'd only send it proactively if the grades materially change the story or the recruiter asked for an update.
