Top of the Morning
Medline yesterday jolted the sleepy IPO market, raising the largest offering in years and then watching shares pop more than 40%.
- It also might have restored faith in leveraged buyouts, at a time when many limited partners in private equity funds are questioning the model's viability.
Catch up quick: We wrote a lot about Medline when it was acquired in 2021, namely because it felt like a nostalgic throwback.
- For starters, the deal was huge. More than $30 billion, in what was one of the largest health-care buyouts ever. And over half the headline number was debt.
- Second, it was a club deal. Three private equity firms — Blackstone, Carlyle, and Hellman & Friedman — that each had identical stakes that, when combined, gave them control. There also was a few billion of sovereign wealth co-invest, while the founding Mills family remained Medline's largest single shareholder.
- Finally, this was never going to be flipped via a trade sale, as Medline was the market leader in hospital supplies by a country mile. Its new debt made a sponsor sale unlikely. Going public was always the goal.
The intrigue: There also was timing risk related to the COVID-19 pandemic.
- Medline's financials still were stuffed with revenue from products like masks, gloves, and testing kits. The buyers had to suss out how much of that excess demand would wane.
- Meanwhile, some rivals abandoned the space. McKesson announced plans to spin off its relevant business, while Owens & Minor last month agreed to sell its unit to Platinum Equity for $375 million.
Zoom in: Medline spent four years growing via over $1 billion in acquisitions and international expansion.
- It filed confidentially for an IPO at the end of 2024 and began serious conversations in March.
- But those plans got waylaid by President Trump's tariff rollout in early April, both because of their impact on Wall Street and also on Medline's actual business.
By the numbers: Blackstone, Carlyle, and H&F invested roughly $3.5 billion into the buyout, Axios Pro's Lucinda Shen reports.
- At yesterday's close, each of those stakes would have been valued at $9.3 billion. Minus any shares sold via a synthetic secondary tied to the IPO.
- It's the sort of return that can calm a lot of LP concerns (much like what SpaceX might do next year for VC fund LPs).
The bottom line: It feels weird to say that private equity needed a win. But it did.
The BFD
Trump Media & Technology Group (Nasdaq: DJT) has agreed to merge in an all-stock deal with TAE Technologies, a VC-backed developer of nuclear fusion technologies.
Why it's the BFD: Trump Media arguably failed at media, generating less than $3 million in sales for the first nine months of 2025, and now is moving onto a regulated technology with higher risks and rewards.
- It's also a reverse merger merry-go-round. Trump Media went public via SPAC in 2024, and now is helping TAE go public.
By the numbers: The deal values the company at $6 billion, with shareholders of each holding a 50% stake on a fully diluted equity basis.
- Trump Media finished trading yesterday with a $2.93 billion market cap, having seen its shares fall nearly 70% year-to-date.
- Lake Forest, California-based TAE was valued at around $6 billion in a 2023 funding round, per PitchBook. Overall it's raised more than $1b from firms like Alphabet, NEA, Goldman Sachs, Kitty Hawk, MicroVentures, Reimagine Ventures, and Chevron Technology Ventures.
The bottom line: Nuclear fusion remains future tech — unlikely to be commercialized while President Trump is in office — but the companies say they plan to begin construction next year on "the world's first utility-scale fusion power plant," which would require government approvals.
