Foolish take
Neptune Insurance went public via an initial public offering (IPO) in October 2025 at a price of $20. It jumped 24% on its first day on the market, indicating positive investor sentiment for the company. Steiner's October purchase of almost 120,000 shares puts his total holdings around 4.4 million shares. An IPO is the most common way for a company to go public, and insiders often buy in at IPO levels. They are typically also beholden to a lock-up period following an IPO, usually at least three to six months, where they cannot sell their shares. It's worth noting that at this time, 38.4% of Neptune's shares are owned by company insiders, according to Simply Wall St. Insider ownership is usually a good sign for retail investors, as it indicates management's goals are aligned with shareholders'.
Investing in IPO stocks can be risky, because the company is as yet unproven on the public market. Neptune reported its first financial results as a public company in November. Third-quarter revenue was $44.4 million, up 31.2% year over year. Its written premiums for the quarter were also up about 31% year over year to $101.6 million. The company reported a 4.8% decrease in net income, which it attributed primarily to costs related to its IPO.
Insurance companies can be a resilient investment area regardless of economic conditions, because it's not an item individuals and businesses are likely to scale back on even during tight times. Neptune's AI-driven approach and asset-light business model is also intriguing. However, investing now means believing in the company and its approach without much public history on which to base your assessment.
