The first 90 days of an add-on decide whether the platform ever integrates

Operators and investors,

Private equity firms moved add-on acquisitions from their least important value lever to their most important one in a single year. FTI Consulting surveyed 555 private equity decision-makers in 14 countries for its 2026 Private Equity Value Creation Index. 24% of them named transactions their top lever against 7% the year before. Cost optimization led the same survey in 2025 and has dropped to fourth place.

Most of these firms do not think they execute acquisitions well. Only 35% call their M&A execution efficient from idea through deal to integration. A quarter see a measurable value contribution from an acquisition twelve months after it closes. A platform that buys three add-ons a year at that rate ends up with more unintegrated businesses than its team can absorb.

Acquirers make the integration decisions that matter before the transaction is done

PwC surveyed 530 C-suite executives and senior dealmakers across six industries and published the results on 29 September 2026. About one in three acquirers fully achieved the objectives of their own deal thesis. The successful acquirers made their main integration decisions before the deal closed.

46% of acquirers had turned their value drivers into initiatives with an owner, a timeline and stated dependencies before integration began. Among acquirers whose deals succeeded the figure was 59%. Among those with limited success it was 28%. PwC calls this 31-point gap the clearest evidence in its survey.

We’ve been involved in different stages for different PE-backed organizations - on the seller side during exit preparedness or due diligence, facilitating the M&A process, participating in the first 100 days or executing the value creation plan. In other instances, we intervene during the hold period, boosting operational alpha with new IP for the org. And we operate for both add-ons and carve outs at DevriX:

This issue covers 4 topics:

• Why the operating model has to be settled before the deal signs

• Why every value driver needs one named owner

• How many integrations a platform can run at once

• What to fix before the next add-on closes

Operating partners underwriting a buy-and-build thesis should read it too. In many of those models the absorption rate is higher than anything the platform has achieved.

1. Why the operating model has to be settled before the deal signs

The operating model is the set of decisions about who reports to whom, which system is the system of record, who sets pricing and which brand the customer sees. If nobody makes those decisions before close, every function spends the first quarter negotiating them.

In 2020, 59% of acquirers in PwC's survey had a target operating model at signing. In 2023 the figure was 61%. On revenue-acceleration deals 71% of successful acquirers had defined the relevant parts of the model before close. Only 44% of the acquirers whose deals underdelivered had done so.

Systems consolidation, headcount decisions and customer communication all depend on the operating model. None of that work can start until someone makes the decision. Most of the first 90 days go into the systems work, and platforms usually hire a digital value creation partner for private equity to run it. By day 90 the add-on is either integrated into the platform or still run as a separate company that reports into the same consolidation. The second case costs more. The company pays for two of every system until someone funds a project to merge them.

2. Why every value driver needs one named owner

Every deal model has a line for the savings the combination is expected to produce. Most of those lines are never assigned to a person with the authority to deliver them and the budget to pay for the work. A different group of people writes the same figures into the value creation plan and nobody reconciles the two plans. Each quarter someone asks whether the number is on track. Three functions each assume one of the others owns it.

62% of successful acquirers were very confident that their reported synergies were real and auditable. Only 27% of the limited-success group were. Fewer than half of all respondents reached that level of confidence. Three in four still tie material incentives to those numbers, so many people are paid on figures nobody can verify.

Naming an owner is the cheapest control at this stage of a deal.

Give each value driver one named person and have finance report realized value next to the forecast in the same view. Teams then spend much less of the second and third quarters after close arguing about who owns what.

Within 60 days you will know which savings are real and still have time to replace the ones that were overstated.

3. How many integrations a platform can run at once

Deal teams are measured on closed deals while operating teams handle everything that comes after. In a platform doing several add-ons a year the two teams work at different speeds, and nobody compares their schedules until something visibly breaks.

Integration capacity comes down to a few specific people: the controller who can map two charts of accounts, the sales leader who can merge two comp plans and the one engineer who understands both ERP instances. If three integrations run at once, the same handful of people have to work on all three no matter how many consultants are on site. More consultants increase the work in progress while the same few people still have to approve all of it.

FTI's respondents named integration complexity, valuation gaps and cultural conflict as their recurring difficulties. 65% rated their own deal execution as inefficient. In my experience these problems show up when a platform buys faster than it can integrate. Agree a limit on concurrent integrations with the deal team before the next letter of intent goes out.

4. What to fix before the next add-on closes

Do this when the platform signs an LOI for an add-on while the previous one is still being integrated. For a platform doing several deals a year that happens often.

Run a 90-minute session with the platform CEO, the CFO and whoever owns post merger integration, and produce 4 things:

• 1. The target operating model for the next add-on: reporting lines, systems of record and pricing authority.

• 2. Every value driver in the model with one named owner and a date. Include the ones that look obvious.

• 3. How many integrations the platform can run at once, counted by the named people each one needs.

• 4. What happens when the deal team wants to sign more than that, agreed in advance.

If nobody in the session can answer one of these, that is probably why the last integration ran long. Signing an add-on before you have the 4 answers means betting that the team will work them out under time pressure. In PwC's survey about two in three acquirers did not fully achieve their deal objectives.

My Take

🔗 Most post-merger integration problems sit in the systems. By month seven many platforms still run two HubSpot instances, three analytics stacks and no single CRM. In my 100-day digital integration plan every initiative has a system decision, an owner and a rollback.

📈 Hitting the growth target in most deal models takes more pipeline than the sales team can build. A $100M company growing 20% with 6% churn needs more than $26M of new business a year. The BDR math behind that number is rarely worked out in the deal model.

💼 I hear from more buyers than sellers right now. Capital allocators with M&A budgets contact me every week and fewer owners are looking to sell. If you run a revenue-generating business and are considering a sale, reply to this email and I will make the right introduction.

⚙️ We built an agent system that reads our four core systems every night. At DevriX we built the AI Ops Hive on our own company first. Agents connected to the project tool, time tracker, code host and finance system answer a fixed set of operating and diligence questions.

🛡️ Three critical vulnerabilities were disclosed within the same 72 hours. They were PHP2Shell, a Node.js remote code execution flaw and a CVSS 10 GitLab advisory. Maintaining vibe-coded stacks that nobody planned to patch is now the real cost.

📰 HackerNoon cited my explanation of why PHP runs so much of the web. Its explainer on the PHP2Shell flaws quotes my point that the LAMP stack let hosts sell cheap plans and that WordPress, Joomla and Drupal followed. Because so many sites run on that stack, one flaw in the PHP runtime affects about 70% of the web.

Blackstone is earning more in fees and selling less. Its Q3 net realizations fell 34% to about $332 million after a nearly 50% drop in private equity. Fee-related earnings from its private equity funds rose 26% to $619 million. When holds run longer, more of the return has to come from what owners build during the hold.

Anthropic filed for a Nasdaq listing under the ticker ANT. Once it lists, boards will have a public market price for a frontier AI company to compare against the AI vendors their portfolio companies use.
