M&A Day 1 Plans: What Should They Cover
The M&A Day 1 plans for HR, IT, Finance, Sales, Communications, Legal, and the IMO in this section cover the six actions that should be completed in every Day 1 launch:
- Ensure system access. Verify minimum viable access for every acquired employee to email, HR portal, and core applications. Activate network connectivity at the start of business and extend security monitoring across the acquired environment.
- Sequence communications. Complete the regulatory filing, then notify employees, the press, and social channels in the proper order. Brief managers with an M&A Communications Employee Guide before they meet with their teams.
- Complete statutory obligations. Execute closing documents, complete contract novations, confirm entity structures, and file required post-close tax notifications.
- Onboard employees and align policies. Launch onboarding for acquired employees and communicate one code of conduct, handbook, and expense policy.
- Engage customers. Send letters from executives to all accounts and call key customers. Equip account representatives with a M&A Communications Guide for customer outreach.
- Run the Day 1 war room. Open early, monitor task completion through the day, address any issues quickly, and debrief workstream leads at the end of the day.
Each workstream has its own tasks to complete on Day 1, but the IMO Day 1 plan ensures everyone operates in synch.
