<div id="readability-page-1"><article>PureTech to maintain its primary listing on the London Stock ExchangeSimplification of listing structure expected to enhance operational efficiency and focus resources on advancing the Company’s portfolio BOSTON--(BUSINESS WIRE)--PureTech Health plc (Nasdaq: PRTC, LSE: PRTC) (&#34;PureTech&#34; or the &#34;Company&#34;), a hub-and-spoke biotherapeutics company dedicated to giving life to science and transforming innovation into value, today announced that it has notified The Nasdaq Stock Market LLC (“Nasdaq”) of its intention to voluntarily delist its American Depositary Shares (“ADSs”), each representing the right to receive ten (10) ordinary shares of the Company. Following the effectiveness of the delisting, PureTech’s ordinary shares will remain listed on the London Stock Exchange (“LSE”), which will continue to serve as the Company’s primary trading venue.Following a review of the Company’s listing structure and shareholder trading patterns, the Board of Directors determined that maintaining a dual listing is no longer necessary. The substantial majority of trading volume, liquidity, and price discovery for PureTech’s shares occurs on the LSE, and the majority of the Company’s current investor base as well as the Company’s governance framework are centered in the United Kingdom.This decision reflects PureTech’s ongoing commitment to disciplined capital allocation, focused execution, and long-term shareholder value creation. The cost and regulatory and administrative demands of maintaining a dual listing are significant, and concentrating trading on the London Stock Exchange will simplify governance, streamline overhead, and align the Company’s structure with its operational and strategic priorities.Following the delisting, and until such time as PureTech may consider terminating its American Depositary Receipt (“ADR”) program, PureTech expects its ADSs to be quoted and traded on the over-the-counter market via a sponsored Level 1 ADR program. No action is required to be taken by ADS holders at this time.Robert Lyne, Chief Executive Officer of PureTech, commented:“We have determined that concentrating our listing on the London Stock Exchange is the most effective way to support our shareholders and execute our strategy. This decision reflects where the meaningful trading volume and liquidity in our shares has consistently occurred, whilst maintaining access to both the UK and global investment community. By simplifying our listing structure, we are streamlining overhead, preserving capital, and ensuring that our resources are focused on advancing our differentiated portfolio and delivering long-term value.”PureTech expects to file a Form 25 with the U.S. Securities and Exchange Commission (“SEC”) relating to the delisting of its ADSs on or about May 11, 2026. The delisting is expected to become effective ten days thereafter, with the last day of trading of the Company’s ADSs on Nasdaq expected to be on or about May 20, 2026.Following the delisting, PureTech intends to file a Form 15F with the SEC to deregister its securities and terminate its reporting obligations under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Upon such filing, the Company’s reporting obligations with the SEC will be suspended immediately. The termination of the Company’s registration and reporting obligations is expected to become effective no later than 90 days after such filing if there are no objections from the SEC.About PureTech HealthPureTech Health is a hub-and-spoke biotherapeutics company dedicated to giving life to science and transforming innovation into value.
