Octans View

Year over year revenue change by quarter, computed from the filed figures: Dec 2025 up 7.5%; Mar 2026 up 15.6%; Jun 2026 up 17.4%; Sep 2026 up 12.9%. On those figures, State Street's revenue growth is slowing. That read compares the latest two year over year growth rates and nothing else.

Bear Case · Room for Disagreement

This brief covers reported revenue and diluted earnings per share only. It does not cover guidance, margins, segment results, cash flow or the earnings call, and it makes no forecast. Revenue is the total on the release line we matched; a company's own adjusted measures can differ.

Method and source. Octans Research matched the revenue line in the earnings release (Exhibit 99.1) to the year ago quarter the company reported in its own XBRL financial data; the two must agree before anything is published. The quarterly history comes from the same XBRL data. The text is generated from those verified figures by a fixed template; no model wrote it.
