Day to day, I work with business valuation and transaction advisory. I’m experienced in the actions that increase value.

Interim M&A Manager – What Does the Role Involve?
An acting M&A Manager is an experienced deal leader who temporarily joins the organization to plan, run, and negotiate transactions. Unlike an external advisor, the short-term leader works hands-on in your day-to-day. From strategy and target screening to due diligence, bidding, and integration, with the goal of securing deals that create long-term value.
Interim or Fractional M&A Manager – What’s the Difference?
An interim M&A Manager joins full-time on a temporary basis to lead time-critical deals, cover leadership gaps, and deliver rapid results. A fractional M&A Manager provides the same senior expertise part-time on an ongoing basis, ideal for building capability, strengthening processes, and supporting a steady deal pipeline without a full-time hire. Oak CEO can fill both kinds of positions.
When Is an Interim M&A Manager Needed?
The need often appears in two situations: when the deal opportunity is here and now, and when you want to build a scalable M&A capability.
1. Time-Critical Deals
When an attractive acquisition appears or a carve-out must be executed, you need pace and precision. An acting M&A Manager can immediately take the lead and:
- Prioritize the right targets and structure outreach
- Coordinate due diligence and secure decision-ready materials
- Drive negotiations and terms work together with legal and audit
The result is higher hit rates, shorter lead times, and deals closed on the right terms.
2. Build M&A Capacity
You can also choose an interim solution to establish or strengthen your M&A function without new hires. This can include:
- Deal strategy, investment criteria, and pipeline
- Processes, templates, and governance for M&A
- PMI planning (post-merger integration) and synergy realization
- Knowledge transfer to the organization: “build to own”
This way you get a scalable, data-driven, and repeatable M&A engine that delivers over time.
What a Short-Term M&A Manager from Oak CEO Can Do for You
1) Strategy & Deal Sourcing
We translate your growth goals into a clear M&A plan: define investment criteria, map and prioritize targets, analyze market logic and competitors’ acquisition behavior, and estimate realistic synergies before first contact.
2) Due Diligence & Sound Valuation
We lead and coordinate financial, commercial, and operational DD and perform valuations grounded in reasonable assumptions, robust data, and sensitivity analyses, not wishful thinking. The aim is to price risk and potential with precision.
3) Negotiation & Deal Execution
Oak CEO takes the lead: contacts sellers, structures the setup (e.g., share/asset deal, earn-out), negotiates LOI and SPA together with attorneys and auditors, and ensures order in data rooms, timelines, and decision materials.
4) Integration & Realized Synergies
We develop a clear integration plan and lead the work so the acquisition or merger runs smoothly. People, processes, and systems are connected without unnecessary disruption, and we follow up with concise analysis and clear reporting. Just need a sounding board? We offer short M&A advisory sessions on structure, valuation, risks, and planning—whether you’re a buyer or seller.
Benefits of Hiring Oak CEO as Your Interim M&A Manager
With a short-term M&A Manager you get the same expertise as a Head of M&A or M&A Director, with greater flexibility. We can step in quickly for shorter or longer engagements, without the time and cost of recruitment.
You gain access to an objective, experienced deal leader who isn’t influenced by internal loyalties or baggage. Our role is to drive the deal forward and create value while working closely with your organization.
Thanks to our background in valuation and transactions, you also get immediate access to specialist knowledge and proven methods that strengthen decisions and increase the odds of a successful outcome.
More Interim Solutions
In addition to an acting M&A Manager, we also offer an Interim CFO for financing and reporting, as well as fractional CEO and CEO roles.
Key Topics to Align With an Interim M&A Manager
For the engagement to deliver fully, clear guardrails are required from the start. Define mandate on bidding, exclusivity, signing thresholds, and which decisions must be anchored with the board. A clear brief reduces friction and accelerates the process.
Examples of items to clarify:
- Authority to initiate and close dialogue cycles with targets
- Mandate to renegotiate commercial terms and supplier agreements in PMI
- Monetary limits for offers, advisor costs, and integration investments
With clear rules of engagement, both owners and the interim M&A Manager can act in sync and maximize value creation in every deal.
