Company Description
The Long-Term Stock Exchange (LTSE) is a U.S. stock exchange that provides a public listing venue and trading services for companies focused on long-term value creation. Its operations also include solutions for late-stage private companies and advocacy for regulatory changes. For example, LTSE has petitioned the U.S. Securities and Exchange Commission (SEC) to allow public companies to report on a semi-annual basis rather than quarterly. The company was founded by Eric Ries and is backed by investors such as MFS Investment Management. A significant event in its history was the SEC's approval of its five principles for long-term corporate governance.
LTSE intends to continue its advocacy work and expand its ecosystem of long-term-oriented companies and investors. Recent announcements include its petition to the SEC regarding reporting frequency, which was reported on by The Wall Street Journal. In a 2025 forecast, Bloomberg Intelligence ranked LTSE as having the narrowest volume-weighted-average spread among independent exchanges. The company's approach to governance has also been featured in the Harvard Law School Forum on Corporate Governance.

Is LTSE worth joining?
Joining any startup involves evaluating its potential and how its equity compensation fits into your financial goals. Platforms like Prospect can help you model the future value of private company stock to make a more informed decision.
What should I do with my LTSE stock?
Managing private company stock requires a clear strategy based on your financial situation, tax implications, and the company's performance. Prospect offers personalized strategies for exercising options and selling shares to help you maximize your post-tax equity value.
Can you sell LTSE stock?
Selling stock in a private company like LTSE is often possible through secondary markets or company-approved tender offers. Prospect provides tools and guidance to help you navigate these sales and determine the most tax-efficient shares to sell.
How can I find the value of my LTSE stock?
Valuing private stock can be complex as it isn't publicly traded, but you can use valuation models that analyze funding rounds and secondary market data. Prospect uses proprietary predictive models to project the future value of your shares, giving you a data-driven estimate.
What is LTSE's equity worth?
The precise worth of a private company's equity fluctuates based on factors like funding rounds, performance, and market conditions. To understand the potential value of your specific holdings, you can use platforms like Prospect to model different financial outcomes.
What is LTSE's stock ticker symbol?
As a private company, LTSE does not have a stock ticker symbol because its shares are not traded on a public stock exchange. Ticker symbols are assigned to companies only when they undergo an Initial Public Offering (IPO).
Can I buy or sell LTSE stock?
Selling private stock is often possible during specific liquidity events like tender offers, and Prospect can help optimize these sales. However, buying shares in a private company is typically restricted to accredited investors or employees and is not a service Prospect facilitates.
What is the criteria to buy or invest in LTSE stock?
Investing in a private company is generally limited to accredited investors who meet specific income or net worth thresholds defined by financial regulators. Employees may also receive equity as part of their compensation package without needing to meet these criteria.
