What you get

Short answer: the SEC exhibit change monitor tracks filing exhibits such as credit agreements, subsidiary lists, certifications, and reference targets, then reports when content changes.

  • Content-verified exhibits

    Know exactly what's in each exhibit.

    For each monitored filer, we hash exhibit content so review starts from the exact document version. Same exhibit number, different content? The change is recorded with source evidence.See the state model
  • Change detection

    Catch silent exhibit swaps.

    When an exhibit changes, including content replaced, reference target changed, exhibit added, or exhibit removed, you get a structured alert with severity and diff context.View change types
  • Evidence records

    Verify any change yourself.

    Each alert includes SEC URLs for both versions, content hashes, diff summaries, and direct links to the original filings.

How it works

We hash exhibit content, compare it across filings, and alert you when something changes. Severity helps you decide what needs review.

Data source

We pull exhibit attachments from SEC EDGAR filings (10-K, 10-Q, 8-K, and amendments) for your monitored filers. Each exhibit is normalized and hashed for comparison.

Tracking changes

We compare each new filing's exhibits against the prior filing of the same type. If content hashes differ, we flag it. If incorporation-by-reference targets change, we flag it.

Delivery

Notifications arrive via email, Slack, or webhook when exhibit changes are detected. Each notification includes severity (HIGH/MEDIUM/INFO), a diff summary, and links to both versions.

  1. Notify me when credit agreement exhibits change.

  2. Track when subsidiary lists (Exhibit 21) are modified.

  3. Let me know if certification exhibits differ from prior filings.

  4. Catch when exhibits are replaced via incorporation-by-reference swaps.

Exhibit changes should be reviewable.

Start with discovery

Five quick steps to proof on your own filers.
1

Choose your filers

Identify the SEC filers you want to monitor by CIK or ticker. Prioritize the ones where silent changes create risk.
2

Select exhibit types

Tell us which exhibit types matter: material contracts (10.x), subsidiary lists (21), certifications (31.x, 32.x), debt instruments (4.x), or all exhibits.
3

Set severity thresholds

Choose which changes you want to see: all changes, only HIGH severity (content replaced, exhibits removed), or a custom mix.
4

Pick a delivery channel

Choose email, Slack, or webhook for notifications. Every alert includes severity, diff summary, and provenance record links.
5

Qualify the outcome

Provide the context, owner, and source material. We will qualify fit and, if there is a real outcome, schedule a two-hour working session.

Common questions

What types of exhibits can you track?

We track all SEC exhibit types, including material contracts (10.x), subsidiary lists (21), consents (23.x), certifications (31.x, 32.x), debt instruments (4.x), and additional exhibits (99.x). Priority can be configured per monitoring engagement.

How do you detect content changes?

We normalize exhibit content (strip HTML, collapse whitespace, standardize redaction markers), then compute SHA256 hashes. If the hash differs from the prior filing, we flag it as a content change.

What about incorporation-by-reference?

We parse exhibit headers to detect when an exhibit references a different prior filing than before. Even if the exhibit number is the same, a reference swap gets flagged.

What severity levels do you use?

HIGH: Content replaced, exhibit removed, reference target changed. MEDIUM: Exhibit added, redaction changes. INFO: No changes detected. You can filter by severity.

Can I verify the hashes myself?

Yes. Every provenance record includes SEC URLs and our normalization rules. You can re-fetch the exhibits, apply the same normalization, and verify the hashes match what we reported.

What happens after the evaluation?

We review detection coverage, evidence completeness, and false positive patterns with you. If it is a fit, we propose a production monitoring plan with scope, delivery targets, operating model, and support responsibilities.

Why teams use this

SEC filings update. Sometimes the narrative mentions the exhibit change. Sometimes it does not. This monitor gives teams an evidence record either way.

  • Catch what slips through

    Credit agreements with tighter covenants, subsidiary lists with new entities, and redacted contracts can change without a useful narrative. Those changes still matter for analysis.

  • Verify it yourself

    Every change includes content hashes and SEC URLs. Your team can re-fetch the exhibits and check the hashes against the evidence record.

  • Prioritize what matters

    Severity ratings help you focus: HIGH for content replacements and removed exhibits, MEDIUM for redaction changes and additions, INFO for no changes detected.
