8-K
Regulatory Filings Classification · 75% confidence The document is a Form 8-K filed under Regulation FD Disclosure announcing that Unitil has posted an investor presentation (Exhibit 99.1) on its website and attached it to the filing. It does not contain the presentation content itself, only an announcement of its posting and exhibit attachment. Under the “menu vs meal” rule, this is a regulatory announcement of a report (the presentation) rather than the report itself, so it should be classified as a general Regulatory Filing (RNS).

8-K
Capital/Financing Update Classification · 90% confidence The document is a Form 8-K current report detailing the entry into a material definitive agreement for the issuance and sale of $40 million in senior unsecured notes (long-term financing) and attachments of the Note Purchase Agreement. This constitutes a capital/financing update as it describes company fundraising and changes in its debt capital structure. There is no presentation of financial statements or detailed management analysis that would classify it as an interim report or annual report, nor is it simply an announcement of a report. Thus, it best fits the Capital/Financing Update category (CAP).

Declaration of Voting Results & Voting Rights Announcements Classification · 100% confidence The document is a Form 8-K filed with the SEC, dated April 29, 2026, reporting the submission of matters to a vote of security holders at the company's Annual Meeting of Shareholders. It includes detailed voting results for director elections, auditor ratification, and executive compensation advisory vote. The content is focused on official voting results from a shareholder meeting, not the meeting materials or the full annual report. The document length is 4103 characters, which is relatively short and consistent with a voting results announcement rather than a full report. Therefore, this filing fits the category of Declaration of Voting Results & Voting Rights Announcements (DVA).
