Deloitte M&A Leader Marty Pletkin on the One Factor That Determines Deal Success

This article was originally posted on the Momentum Mode Podcast Substack channel, featuring Impruve CEO Mike Shannon.

In the world of mergers and acquisitions, founders often assume that deals hinge on financial models, valuation frameworks, or legal diligence.

Those factors matter, but they are rarely decisive.

As longtime M&A executive Marty Pletkin, Managing Director of Corporate Development at Deloitte, explained in a recent episode of Momentum Mode, after decades of transactions across Deloitte, Vodafone, and other global organizations, deals ultimately succeed for a far simpler reason: alignment of intent between leaders.

When one CEO truly wants to buy, and another genuinely wants to sell, the transaction happens.

When that alignment doesn’t exist, no amount of analysis can force a deal across the finish line.

The Myth of Financial Determinism

Founders frequently overestimate the role of financial mechanics in determining outcomes.

They focus on projections, synergy models, or valuation arguments. These are important components of any transaction, but they rarely determine whether a deal proceeds.

According to Pletkin, the real determinant is leadership conviction.

Diligence can uncover risks. Financial models can validate assumptions. But neither can compensate for the lack of strategic alignment between decision-makers.

In practice, the decision to transact is often emotional before it is analytical.

The Founder’s Hidden Risk During Diligence

One of the most counterintuitive lessons from Pletkin’s experience is where deals most often fail.

It is not usually due to price disagreements or legal obstacles.

Instead, many transactions collapse because founders become overly consumed by the process itself.

During extended diligence periods, leaders frequently shift their attention away from running the business. Operational performance begins to slip. Growth slows. Momentum weakens.

By the time negotiations reach critical stages, the company no longer looks as attractive as it did at the outset.

The irony is clear: the very process designed to unlock value can erode it.

Pletkin’s advice is blunt: never take your eye off the business you are selling.

Time as the Most Dangerous Variable

Another insight that runs counter to common assumptions is the role of time.

Many founders believe extended negotiations signal thoroughness and professionalism. In reality, prolonged timelines introduce significant risk.

Time can kill deals in multiple ways:

• Strategic priorities shift inside the acquiring organization

• New internal stakeholders introduce objections

• Market conditions change

• Competing opportunities emerge

• The seller’s business performance declines

Even when transactions ultimately close, extended timelines often leave lasting operational damage.

For this reason, experienced acquirers prioritize speed and responsiveness, not as a negotiation tactic, but as a risk mitigation strategy.

The Power Dynamics of Selling

Founders also frequently misunderstand leverage in M&A negotiations.

The conventional wisdom suggests that buyers hold all power because they control capital.

Pletkin challenges this assumption.

When a company possesses a strong business, credible growth trajectory, and strategic relevance, sellers retain significant influence over the process.

This leverage manifests in practical ways:

• Setting firm timelines

• Demanding responsiveness from buyers

• Limiting exclusivity periods

• Ensuring operational continuity during negotiations

In essence, successful sellers treat the transaction as a partnership rather than a surrender of control.

Strategic Buyers Think Differently

Another key distinction highlighted in the conversation is the mindset of strategic buyers compared to private equity firms.

Strategic acquirers are not seeking short-term financial returns. They are seeking capabilities that can integrate into existing client networks, operational systems, and long-term strategies.

For these buyers, the value of a target company lies less in cost synergies and more in strategic fit.

This perspective fundamentally reshapes how deals are evaluated.

Instead of asking, “How much can we cut?” strategic buyers ask, “How can we amplify what this company already does well?”

Lessons for Leaders

Pletkin’s decades of experience reveal several enduring principles:

First, leadership alignment determines deal viability more than financial analysis.

Second, founders must continue operating their businesses aggressively throughout the process.

Third, speed and clarity reduce risk for both sides.

Finally, successful transactions depend less on negotiation tactics and more on mutual strategic conviction.

Beyond Transactions

Perhaps the most important takeaway is that M&A is not purely a financial exercise.

It is a leadership decision.

Behind every successful deal are individuals making high-stakes judgments about strategy, timing, trust, and long-term vision.

As Pletkin’s experience demonstrates, the mechanics of deals are complex.

But the reasons they succeed are often surprisingly simple.
