The 2020-2021 biotech "bubble" pushed very early-stage companies into public markets prematurely. The subsequent correction, though painful, has been a healthy reset. It has forced the sector back toward a more suitable, long-duration private funding model where companies can mature before facing public market pressures.

The public markets exhibit extreme short-termism. The immediate post-deal performance of follow-on financings heavily influences investor sentiment for subsequent deals. Poor performance one week empowers insiders to demand steeper discounts the next, creating a volatile feedback loop.

Unlike the 2020-2022 bubble, the expected wave of biotech IPOs features mid-to-late-stage companies with de-risked assets. The market's recent discipline, forced by a tough funding environment, has created a backlog of high-quality private companies that are better prepared for public markets than their predecessors.

The recent rally in some biotech stocks is likely just the beginning. Key indicators of a full-blown bull market, such as a resurgence in biotech IPOs and a rally in large tool companies (e.g., Thermo Fisher), have not yet occurred, suggesting the cycle is still in its early innings.

While staying private can offer strategic advantages, particularly for future M&A, the biotech industry lacks a mature private growth capital market. Companies needing hundreds of millions for late-stage trials have no choice but to go public, unlike their tech counterparts.

The life sciences investor base is highly technical, demanding concrete data and a clear path to profitability. This rigor acts as a natural barrier to the kind of narrative-driven, AI-fueled hype seen in other sectors, delaying froth until fundamental catalysts are proven.

The biotech ecosystem is a continuous conveyor belt from seed funding to IPO, culminating in acquisition by large biopharma. The recent industry-wide stall wasn't a failure of science, but a halt in M&A activity that backed up the entire system.

Unlike in tech where an IPO is often a liquidity event for early investors, a biotech IPO is an "entrance." It functions as a financing round to bring in public market capital needed for expensive late-stage trials. The true exit for investors is typically a future acquisition.

The past few years in biotech mirrored the tech dot-com bust, driven by fading post-COVID exuberance, interest rate hikes, and slower-than-hoped commercialization of new modalities like gene editing. This was caused by a confluence of factors, creating a tough environment for companies that raised capital during the peak.
