Checklist: Vendor Due Diligence When Picking AI Suppliers After a High-Profile Acquisition

Hook: Your AI supplier just changed owners — now what?

High-profile AI acquisitions like the moves we saw around late 2025 and early 2026 (including strategic plays for FedRAMP-certified stacks) create immediate uncertainty for operations and procurement teams. Your vendor's governance, risk posture, product roadmap, and even contract terms can change overnight. If you use that AI in production, that uncertainty becomes your operational risk.

The bottom line first: immediate priorities after an AI M&A

Act quickly, assess deeply, plan a 90-day roadmap. Your goal is to validate continuity, measure integration risk, protect data and IP, and negotiate remediation steps where the M&A introduces unacceptable exposure.

• Confirm service continuity and immediate SLA commitments.
• Assess financial and personnel stability for the product line you use.
• Validate regulatory and compliance implications (FedRAMP, EU AI Act, data residency).
• Put a prioritized remediation and exit plan in place.

Why this matters now (2026 context)

AI vendor consolidation accelerated through late 2025 and into 2026 as established cloud and defense-focused companies ate up specialized model and platform vendors. That wave brought advantages (scale, compliance posture) but also risks: product rationalization, customer concentration, and shifts in go-to-market strategy. Governments and large enterprise buyers have tightened procurement scrutiny, and regulatory attention (notably around safety, provenance, and provider consolidation) increased in late 2025. Procurement teams must treat post-M&A events as a new risk class.

How to use this checklist

This checklist is actionable and structured for procurement and operations teams. Start with an immediate triage (0–7 days), then a tightened due diligence (30 days) and a remediation + integration plan (60–90 days). Use the scorecard to prioritize vendor engagement and negotiating levers.

Immediate triage (0–7 days)

• Confirm contract status: Do change-of-control clauses, contract termination rights, and assignment restrictions kick in? Flag clauses you can exercise.
• Verify operational continuity: Is there any announced or planned product sunset, migration, or roadmap pause?
• Check SLAs and critical services: Are support windows, uptime SLAs, and escalation paths unchanged?
• Escalate with vendor account team: Request a written continuity statement and single point of contact for the transition.
• Lock documentation and export data: Export backups, data exports, and configuration snapshots for key workloads.

Short-term due diligence (30 days)

Within the first month, deepen your assessment across finance, technology, security, compliance, and people.

• Financial health review: Request or validate the vendor's financial statements, revenue trends for the product you use, and any disclosed debt or capital changes tied to the acquisition.
• Customer concentration and churn: Ask for customer retention metrics and whether large anchor customers are being migrated or reprioritized.
• People and leadership stability: Verify which product and engineering teams are staying, and whether there are layoffs or leadership changes affecting support and roadmap.
• Product roadmap and integration plan: Demand a roadmap commitment for the next 12 months and ask how the acquiring company plans to integrate or rationalize the acquired product.
• Security and compliance posture: Validate certifications (FedRAMP, SOC 2, ISO 27001), and ask for a statement of continuity for compliance responsibilities post-M&A.
• Data handling and residency: Confirm data migration plans, third-party sharing, and whether data will be transferred across jurisdictions or to new cloud providers.

Remediation & integration planning (60–90 days)

Use this phase to negotiate contractual protections, operational runbooks, and to prepare contingency options should the vendor deprioritize your functionality.

• Negotiate change-of-control protections: Seek explicit service level, support, and roadmap commitments for a defined period post-acquisition.
• Secure data exit terms: Define data export formats, timing, fees, and verification steps. Insist on escrow or escrow-like arrangements when possible.
• Ask for migration assistance credits: If product discontinuation is likely, negotiate transition support — personnel hours, engineering assistance, or financial credits for migration.
• Strengthen IP and model rights: Clarify ownership of fine-tuned models, derivative works, and rights to reproduce or rehost models for continuity.
• Run an integration test: Create a short pilot to validate that the product still functions as expected under the new owner’s environment.

Vendor Risk Checklist — fields every operations/procurement team should capture

Below is a practical checklist to capture during vendor reassessment. Score each item and use the weighting to create a composite risk score.

Core checklist items

1. Contract & Legal
   • Change-of-control clauses and remedies
   • Termination rights and exit windows
   • Assignment and subcontracting rules
2. Financial
   • Revenue trend for that product line
   • Debt, liabilities, and balance-sheet risks
   • Customer concentration (% revenue from top 5 customers)
3. Operational & Technical
   • Roadmap commitments and stated product shelf-life
   • Integration compatibility (APIs, data formats, SDKs)
   • Support SLAs and escalation contacts
4. Security & Compliance
   • FedRAMP/SOC2/ISO status and transfer of attestation
   • Data residency and transfer guarantees
   • Model governance and provenance documentation
5. People & Knowledge Transfer
   • Retention of core product engineers
   • Availability of runbooks, architecture diagrams, and source-of-truth docs
   • Training availability for successor teams
6. Strategic Fit & Roadmap Risk
   • Evidence the acquiring company intends to support your use case
   • Overlap with acquirer's existing products and rationalization risk

Suggested weighting (example)

• Financial: 25%
• Security & Compliance: 20%
• Operational & Technical: 20%
• Contract & Legal: 15%
• People & Knowledge Transfer: 10%
• Strategic Fit: 10%

Score each item 1–5, multiply by the weighting, and sum for a composite risk rating. Prioritize remediation for the highest-scoring risks.

Red flags that demand immediate action

• Product sunset announcement: If the vendor publicly or privately signals deprecation, accelerate migration planning.
• Loss of key personnel: High attrition in the product engineering or customer success teams is a leading indicator of degradation.
• Contractual uncertainty: If the vendor refuses to provide written continuity commitments or withdraws accepted SLAs.
• Data transfer without consent: Any plan to move data to a different jurisdiction or cloud provider without clear controls.
• Regulatory exposure: If the acquiring company has pending regulatory issues that could affect access (e.g., export controls, CFIUS reviews for defense-related AI).

Negotiation playbook: clauses to push now

Negotiation leverage tends to be stronger in the immediate post-M&A window when the vendor wants to show customer stability. Use that window to secure protections:

• Bridge commitments: A 12–24 month service commitment covering feature support and SLAs.
• Data export and escrow: Mechanisms to retrieve your data in open, documented formats at no extra cost if service is terminated.
• Migration assistance: Defined scope of engineering support, timelines, and credits for migration to an alternate solution.
• Escrow for models and IP: Where feasible, escrow trained model artifacts and training data schemas so you can rehost or port models.
• Service credits and penalties: Expand SLA remedies to include financial credits for disruption during the transition.

Operational playbook: 30–60–90 day checklist

Use a short operational plan to translate diligence into action. Below is a working 30/60/90 roadmap.

Days 0–30

• Execute immediate triage tasks (data exports, written continuity assurance).
• Run the vendor risk scorecard and identify top 3 risks.
• Set up a cross-functional review (procurement, legal, security, engineering).

Days 31–60

• Negotiate targeted contractual protections (escrow, migration assistance).
• Conduct a pilot/integration trial to validate product behavior under the new owner.
• Build contingency integrations (alternate provider evaluation, export/import validation).

Days 61–90

• Finalize migration plan if needed; begin phased migration or divergence.
• Update internal runbooks, incident response plans, and OKRs to reflect new vendor risk posture.
• Agree on KPIs and a governance cadence with the vendor for quarterly health checks.

Technical specifics: what to validate for AI platforms

AI platforms have unique risk vectors compared with traditional software. Validate these specifics:

• Model provenance and lineage: Can the vendor provide reproducible training records, dataset lineage, and fine-tune histories?
• Fine-tuned models ownership: Who owns the weights and derivative models trained on your data?
• APIs and compatibility: Are public APIs stable? Are deprecation timelines clearly documented and committed?
• Retraining and drift management: What are the vendor’s policies for retraining, update frequency, and rollback mechanisms?
• Supply chain dependencies: If the acquiring company relies on other cloud or third-party services, confirm those dependencies and SLAs.

Case example: What went wrong — and what we’d do differently

In late 2025 several mid-market buyers experienced sudden roadmap pauses after smaller AI vendors were acquired by larger enterprises prioritizing consolidation. Common failures: customers lacked contractual export rights, and key engineers were reassigned. If your team faces a similar scenario, the immediate win is to secure written continuity and export commitments and to create a fallback plan that can be executed within 60 days.

Practical takeaway: Use the acquisition as a trigger event — not a negotiation timeout. You gain leverage to secure time-limited commitments and migration assistance.

How to measure when to exit — objective criteria

Make exit decisions using objective thresholds you define now. Examples:

• Loss of 25%+ core engineering personnel working on your product within 90 days.
• Failure to receive written continuity or roadmap commitment within 30 days.
• Evidence of data jurisdiction changes that violate compliance requirements.
• Three or more SLA breaches in a rolling 90-day period without remediation.

Dashboard and KPI suggestions for ongoing monitoring

Create a vendor health dashboard to monitor the most predictive indicators of vendor stability.

• Composite vendor risk score (weekly update)
• Product NRR (net revenue retention) for that product line
• Support ticket volume and average time to resolution
• Security/incidents reported and time to closure
• Headcount assigned to product and customer success

Future-facing: 2026 trends your checklist should reflect

In 2026 procurement teams must incorporate macrotrends into vendor assessments:

• Continued consolidation: Expect more M&A, especially where acquirers seek FedRAMP or industry-specific certifications.
• Regulatory tailwinds: Enforcement of AI regulations (safety, provenance, auditability) will alter obligations for both vendors and buyers.
• Escrow and portability norms: Escrow for models and portability guarantees will become standard negotiation items.
• Third-party risk visibility: Tools that map vendor supply chains and runtime dependencies will be critical for continuous due diligence.

Final actionable checklist (one-page summary)

1. 0–7 days: Export data, request written continuity, run triage scorecard.
2. 30 days: Validate finances, compliance (FedRAMP/SOC2), people, and roadmap.
3. 60 days: Negotiate contractual protections—escrow, migration assistance, SLA credits.
4. 90 days: Execute migration or integration plan; set governance cadence and dashboard KPIs.
5. Ongoing: Monitor vendor health metrics weekly and trigger exit criteria objectively.
