Important, Potentially Price-Sensitive Updates for Shareholders

• Commercialization of CARDAMYST:
  • Milestone’s expectations regarding the commercialization of its lead product, CARDAMYST, will be central to the company’s future revenue and profitability.
  • Investors should note that greater-than-expected product returns could exceed the company’s reserve for returns, potentially impacting revenue and operating results.
• Financing and Capital Requirements:
  • The company explicitly warns that raising additional capital may cause dilution for current shareholders, restrict operations, or require relinquishing rights to product candidates.
  • Milestone’s ability to secure future funding is essential to its working capital and the implementation of strategic plans, including research and new product development.
• Regulatory and Market Risks:
  • Delays or failures in obtaining regulatory approval for new indications or future candidates could materially impact future growth.
  • Milestone is subject to U.S. and Canadian regulatory oversight, including FDA and other jurisdictional requirements. Any marketing restrictions, fines, or recalls could lead to significant financial and reputational damage.
• Competitive Environment:
  • The report highlights the competitive nature of the cardiovascular therapy market. Failure to compete effectively or respond to industry developments may impact future performance.
• Stock Volatility and Liquidity:
  • Milestone’s shares are described as “thinly traded,” and the market price has been—and may remain—highly volatile, which could expose investors to significant price swings and liquidity risk.
  • Share ownership is concentrated among executives, directors, and principal shareholders, which may limit the influence of new investors on significant corporate decisions.
• Legal and Compliance Risks:
  • The company is subject to a range of U.S. and Canadian laws, including anti-kickback and false claims statutes, data privacy, and transparency regulations. Regulatory non-compliance could result in fines, product withdrawal, or operational restrictions.
