What is SPAC?
A Special Purpose Acquisition Company raises money through an IPO to acquire a private company - a backdoor to going public without a traditional IPO.
A SPAC (Special Purpose Acquisition Company) is a shell company that raises money through an IPO with the sole purpose of acquiring a private company, effectively taking it public without a traditional IPO process.
How SPACs work:
- Formation: Sponsors create a blank-check company with no operations
- IPO: SPAC raises capital from public investors (typically at $10/share)
- Search: SPAC has 18-24 months to find and merge with a target
- Merger: Private company merges with SPAC and becomes public
- Redemption: If you don't like the target, you can redeem shares for ~$10
Why companies use SPACs: Faster than traditional IPO (3-4 months vs 12-18), more pricing certainty, and ability to share forward projections.
Risks: Sponsor dilution, poor target selection, and historically weak post-merger performance.
Lessons from the SPAC boom: The 2021 SPAC frenzy saw hundreds of blank-check companies flood the market, many merging with unprofitable targets at inflated valuations. By 2023, SPAC activity had dropped over 90% as regulators tightened rules and investors grew skeptical. The key takeaway: SPACs can offer legitimate paths to public markets, but investors must scrutinize sponsor incentives, target quality, and dilution before committing capital.
