100-day plan

Convert diligence findings into a sequenced first-100-day programme that protects continuity, establishes control and starts priority value initiatives.

Quick answer

A 100-day plan is a time-bound post-acquisition execution plan covering the most important early actions for control, continuity, performance and value creation. It normally defines workstreams, milestones, owners, resources, dependencies, decisions, risks and acceptance evidence.

Use the worked example

Meaning and transaction use

A KKR-related SEC filing states that a 100-day plan is developed during diligence, covers immediate post-acquisition operational issues and is reviewed after the first 100 days. [S1]

Another SEC filing describes a formal plan setting near-term objectives and beginning a longer strategic plan. [S2]

Proposed control method: connect each milestone to a diligence finding, value driver, risk or control requirement.

Worked example

Illustrative plan only. Assume 50 milestones are due by day 100: 39 accepted on time, 5 accepted late, 4 open and 2 blocked.

Scroll the table horizontally to view all columns.

Measure	Calculation	Result
Accepted on time	39 / 50	78%
Accepted late	5 / 50	10%
Open	4 / 50	8%
Blocked	2 / 50	4%

The illustrative on-time rate is 78%; eleven milestones require delay, completion or blocker action.

Proposed transaction review process

Translate diligence

Convert findings into outcomes, owners and deadlines.

Sequence priorities

Plan Day 1, first 30 days, days 31-60 and days 61-100.

Run governance

Track actions, decisions, dependencies, costs and risks weekly.

Review day 100

Accept results, reforecast open items and transition to the value plan.

Evidence checklist

Inputs

Diligence reports, deal thesis, risks and synergy case.

Plan

Workstreams, owners, milestones, budget and dependencies.

Execution

Actions, decisions, issue log and acceptance records.

Outcome

Day-100 review, KPI movement, value evidence and next-phase plan.

Decision framework

Situation	Proposed action
A Day 1 risk remains	Apply the contingency and escalate closing readiness.
Resources are insufficient	Reprioritise critical milestones and approve capacity.
A hypothesis fails	Update the value case and stop unsupported activity.
An action lacks evidence	Keep it open until acceptance criteria are met.

Common errors to check

Starting the plan after closing.
Listing activities without measurable outcomes.
Ignoring dependencies and resource constraints.
Closing milestones without acceptance evidence.
