The worst-performing companies from the IPO class of 2025 are facing a negative feedback loop as lock-up periods expire after earnings, according to the head of PricewaterhouseCoopers' US listing practice. These restrictions have prevented insiders from selling shares, but now early investors and management teams can cash out, potentially triggering further price declines.

Lock-up expirations have historically created selling pressure for newly public companies, especially those trading below their IPO prices. When insiders begin selling, it often signals lack of confidence to the market, causing share prices to drop further. This downward spiral can accelerate as more investors rush to exit positions before prices fall even more.

For the IPO class of 2025, this timing is particularly problematic. Companies going public during periods of market uncertainty often see their shares struggle from day one. Now, with lock-ups ending after quarterly earnings reports, any disappointing results could amplify selling pressure. The PricewaterhouseCoopers executive warns that this combination of factors creates a perfect storm for these underperforming stocks.
