KPIs for Measuring M&A Success in the First 12 Months

By Glazix | May 29, 2025

The deal is done. Now comes the real scoreboard.

In glass, ceramics, and broader materials M&A, closing the transaction is only the beginning. What matters most is whether the deal delivers value in the first 12 months. That’s where KPIs—key performance indicators—turn theory into measurable performance.

Here are the KPIs that best signal M&A success in the industrial materials sector during the first year post-close.

1. Revenue Retention Rate

This measures what percent of the acquired company’s revenue is retained at Day 365.

✅ Why it matters: High customer churn is a red flag that integration or messaging failed.

🎯 Target: ≥90% retention in non-seasonal sectors, with extra scrutiny on top 20 customers.

2. Gross Margin Stability

Are gross margins holding steady—or eroding due to production inefficiencies, freight costs, or pricing missteps?

✅ Why it matters: Gross margin erosion indicates operational strain or poorly managed synergies.

🎯 Target: Maintain or improve pre-close margin within ±1.5%, with clear attribution if declines occur.

3. Synergy Realization (% of Target Achieved)

How much of the projected cost savings or revenue lift have you actually captured?

Break down by:

SG&A reduction

Procurement savings

Freight optimization

Cross-sell success

🎯 Target: 50%+ synergy capture by Month 12, with full realization within 24 months.

4. Talent Retention in Critical Roles

Track retention for:

Top commercial accounts managers

Key plant or operations leaders

R&D and technical specialists

✅ Why it matters**: Losing institutional knowledge or customer-facing talent delays ROI.

🎯 Target: ≥85% retention of “Tier 1” personnel in Year 1.

5. Integration Milestone Completion

Establish and track a formal integration roadmap across:

Finance (ERP alignment, reporting)

HR (benefits, payroll)

Sales (CRM, quoting tools)

Ops (SOPs, safety, inventory)

🎯 Target: 80–90% completion by Day 365, adjusted for deal complexity.

6. Customer NPS or Satisfaction Delta

Conduct surveys pre-close and at Months 6 and 12 to gauge:

Service quality

Communication effectiveness

Overall satisfaction

🎯 Target: No more than 5-point NPS drop; ideally a gain if service improves.

7. EBITDA Growth vs. Budget

Was the deal accretive? Track actual vs. pro forma adjusted EBITDA.

🎯 Target: Meet or exceed acquisition model by at least 90% by Month 12.
