Capital markets communications: the high-stakes playbook

Capital markets communications gets tested when the stakes are already high. A funding decision is approaching. A transaction is in motion. A short seller has published an attack, and the market wants an answer before the company has had time to catch its breath. In those moments, saying more is not always safer. The job is to know what matters, who needs to hear it, and what the market will do with the message once it leaves the room.

Zack Mukewa has spent 21 years across global markets, on a path from Kenya to New York. Today he is Principal and Head of Capital Markets and Strategic Advisory at Sloane. On episode 5 of The Connector’s Table, he explained what strong communication looks like when a company’s funding, reputation, or stock price is on the line.

What is capital markets communications?

Capital markets communications is the work of advising companies through moments that can move a stock price or shape a funding decision, including earnings, attacks, and transactions. It is narrative work backed by market mechanics. The story has to be clear, but it also has to make sense to the people supplying, moving, or judging the capital.

That requires a wider view than public relations alone. Zack works across the full continuum of capital: founders bootstrapping in a garage, portfolio companies planning exits, and public companies going private. The task changes at each point, but the central question holds. Who is the best-fit capital partner for this particular story?

Good communication starts by understanding what the business could become, then connecting that possibility to a capital partner equipped to see it.

How should a company respond to a short seller attack?

A company facing a short seller or activist attack should not rebut the report line by line. It should isolate the two or three credible claims buried inside the aggressive framing and answer only those, precisely. The objective is not to win an argument with every sentence. It is to address what the market may reasonably care about without lending the entire report more weight.

Zack puts the risk plainly: “If you are rebutting line by line, you are telling the market the report was worth rebutting.”

The instinct is to correct everything, especially when the framing is designed to provoke a reaction. But a comprehensive rebuttal lets the attacker set the agenda. It asks investors to inspect every allegation and treats every point as if it deserves equal consideration.

A more controlled response separates signal from noise. Find the claims with enough substance to affect confidence. Answer them with precision. Leave the rest outside the frame. In a high-pressure moment, restraint is part of the strategy.

Why do early-stage companies miss out on funding?

Early-stage companies often miss out on funding because investors fixate on the financial model and overlook the bigger story of what the business could become. The model matters, but the story is part of the raise. If the future is not legible, a spreadsheet cannot make it compelling on its own.

The answer is not to replace financial substance with a grand vision. It is to connect them. The model gives the story discipline. The story gives the model meaning. Capital markets communications has to hold both at once, because a credible forecast without a larger case can leave the opportunity looking smaller than it is.

What are second-order effects and why do they matter?

Second-order effects are the consequences of a major decision that surface later through systems nobody was watching. They matter because the most consequential outcome almost never arrives on the day the decision is made. Smart people can solve the right problem in the wrong system, then discover the real cost somewhere else.

A decision can look contained when viewed from a single team, stakeholder group, or timeline. Its effects are not necessarily contained. What changes for one player can alter the incentives of another, which can create a reaction far from the original choice. By the time that reaction becomes visible, the organization may be responding to a consequence it never included in the first analysis.

The practical lesson is to look beyond the immediate result. Ask what the decision changes next, who responds to that change, and which connected system absorbs the pressure. The first answer may explain the action. The second or third may explain the outcome.

How do leaders avoid being blindsided?

Leaders avoid being blindsided by mapping and engaging every stakeholder in the ecosystem before a major decision hardens. Strong stakeholder engagement is the defense because it exposes hidden pitfalls and unexpected opportunities early, while there is still room to respond.

The map should be wider than the obvious decision makers. Every player has a position, an incentive, and a way of influencing what happens next. Listening across that system helps a leader see where the stated problem differs from the actual one, and where a seemingly distant stakeholder may shape the result.

This is not about collecting opinions until a decision becomes impossible. It is about understanding the system well enough to act without being surprised by it. For the longer version of Zack’s thinking, read the companion essay on stakeholder mapping and second-order effects.
