The Renk IPO - Defense from Private to Public - Susanne Wiegand and Christian Schulz (IPO Stories, Ep. 42)

In this episode of IPO Stories, we speak with Susanne Wiegand and Christian Schulz, former CEO and CFO of RENK, one of Europe’s most important defense suppliers. RENK, a 150-year-old German industrial company specializing in high-performance transmissions for tanks and naval vessels, listed in Germany in February 2024 and is now valued at over €6 billion, with shares up more than 300% since the IPO. The listing came at a moment when Europe’s security environment — and investor perception of defense — was undergoing a profound shift. Susanne and Christian describe how geopolitics fundamentally reshaped RENK’s strategy, investor base, and capital structure. Defense was no longer a niche or cyclical business, but a long-term structural growth market. Independence mattered. Speed mattered. And access to public equity became essential to scale capacity, invest ahead of demand, and remain a neutral supplier to all major primes. The episode offers a rare inside view into how leadership teams must sometimes move faster — and think more clearly — than both advisers and markets. Beyond the transaction itself, this conversation is about judgment under pressure. How do you educate investors when sentiment lags reality? How do you build conviction in a misunderstood sector? And what does it really take — culturally, operationally, and personally — to lead a company into public markets when history is moving faster than capital markets? This is an episode about leadership, credibility, and why Europe’s defense industry is entering a fundamentally new chapter.

Apollo's IPO Playbook - Michael Shapiro (IPO Stories, Ep. 34)

In this episode we sit down with Michael Shapiro, Apollo's co-head of Capital Markets and Syndicate, to unpack what it really takes to engineer a successful IPO in today’s market. Drawing on Apollo’s deep experience across public and private markets—including recent IPOs like Lottomatica in Italy, Sun Country in the US, and Ventia in Australia —Michael explains how the firm builds IPO readiness from the moment of investment, why purchase price matters more than ever, and how to turn complex businesses into compelling public stories. We dive into the practical playbook Apollo uses: early investor engagement, dry-run earnings reports, capital structure optimization, and building credibility long before the listing. Michael also challenges old assumptions about investor categories, advocating for a focus on fundamentals over labels like “long-only” or “hedge fund.” Throughout the conversation, he emphasizes the importance of predictability, simplicity, and investor alignment to maximize post-IPO performance. Whether you're a company preparing to go public, an investor evaluating IPOs, or simply fascinated by how public markets work, this episode offers a masterclass in IPO execution from one of the industry's top capital markets practitioners.

Passive investors and IPOs - Prof. Marco Sammon (IPO Stories, Ep. 33)

Marco Sammon is an assistant professor in the Finance Unit at Harvard Business School. He and his co-authors have researched on how indexing interacts with IPOs, particularly relating to fast-track additions to equity indices in the US, and the behaviour of firms in response to equity index rebalancing. With Marco, we try to draw some conclusions for investors and management teams about how to adapt to the growing share of passive ownership in equity markets – which can be both frustrating at times, and beneficial to companies going public.
