⟁ We track silent changes in SEC filings
By Rada Vassil. July, 2025
DeltaSignal AI analyzes SEC filings by comparing each one to its previous version. It looks at individual financial metrics, not just the text. It tracks if a number changes — even if it’s buried in a table — and flags it. DeltaSignal AI links that change to the original filing ID (accession number), so you can see exactly where it came from and when. If a GAAP value is restated, reclassified, or backfilled, DeltaSignal AI catches it. You know exactly where the change appeared and when it was filed.
Most tools use text parsing. They try to read the language of the filing and summarize it. That misses structural edits, like silent reclassifications or backfilled values.
DeltaSignal AI takes a structural approach: it compares the actual data structure of one filing to the one before it. That means it doesn’t rely on what the company says — it checks what they did.
It reads the actual filing layout, line items, and data hierarchy. That’s how it catches silent shifts — the ones that don’t show up in press releases or summaries, but still affect valuation, audit scope, or risk.
This matters because SEC rules don’t require filers to explain every revision. There’s no redline. No alert. If you’re not comparing structurally, you’re not seeing the whole picture. If you’re only reading summaries or text, you’ll miss those shifts.
DeltaSignal AI fills that gap.
✧ It shows you what actually changed — even if the company never mentioned it.
✧ What changed. When it changed. Where it came from.
✧ Fully sourced. Version-aware.
That’s critical for analysts, auditors, and compliance teams who need accuracy, not interpretation.
Why it matters:
• You catch revisions that aren’t disclosed
• You know where the change came from — and when
• You’re working with real, auditable data — not interpretations
This gives you confidence in the trail, even when the narrative stays quiet.
Even when the narrative stays quiet, the data tells the story.
DeltaSignal AI makes sure you see it.
