This filing relates to the proposed merger of TCR2 Therapeutics Inc., a Delaware corporation (the “Company”), with CM Merger Sub, Inc. (“Merger Sub”), a Delaware corporation and an indirect wholly-owned subsidiary of Adaptimmune Therapeutics plc (“Parent”) a public limited company incorporated in England and Wales, pursuant to the terms of that certain Agreement and Plan of Merger, dated as of March 5, 2023, by and among the Company, Merger Sub, and Parent (the “Merger Agreement”).

 

1.What was announced?

 

·TCR2 announced a strategic combination with Adaptimmune Therapeutics aimed at creating a preeminent cell therapy company for solid tumors.

·This is an exciting milestone for both TCR2 and Adaptimmune.

·The combination brings together two highly complementary and patient-centric businesses to create new opportunities for our company – and for our employees.

·Combining with Adaptimmune will give us a stronger foundation to achieve our longstanding goal of bringing to cancer patients an innovative set of potentially curative therapies.

·The transaction is currently expected to close in Q2 2023.

 

2.Who is Adaptimmune Therapeutics?

 

·Adaptimmune is a leader in TCR-specific cell therapy, focused on designing and delivering novel cancer immunotherapy products.

·Their clinical pipeline is led by afami-cel for the treatment of people with synovial sarcoma and they are on track to submit a BLA by mid-year making it the first TCR therapy approvable for solid tumors.

·They also have a deep preclinical pipeline with multiple second generation autologous and allogeneic approaches backed by a proprietary TCR platform that is complementary to ours.

·For more information, please visit https://www.adaptimmune.com/.

 

3.Why is TCR2 merging with Adaptimmune Therapeutics?

 

·As you know, focus and specialization are critical in the cell therapy space, and we believe the combined company will have the technologies and financial basis necessary to succeed in a very competitive and capital intensive space.

·We will have a deep bench of cell therapy professionals, infrastructure and end-to-end capabilities that could be applied across an even broader portfolio of innovations, with a cash runway anticipated to extend into 2026.

·Combining with Adaptimmune will give us a stronger foundation to achieve our longstanding goal of bringing to cancer patients an innovative set of potentially curative therapies.

·Overall, with the impressive capabilities from both organizations, we can reach even greater heights than we could have achieved on our own.

 

4.What does this mean for employees?

 

·We are confident that TCR2 and Adaptimmune are terrific partners.

·With the impressive capabilities from both organizations, we can reach even greater heights of patient care and innovation than we could have achieved on our own.

·Importantly, it is clear that we share not just a common vision, but a deep belief in our people.

·From our many interactions with Adaptimmune, we have discovered that Adaptimmune has a culture very similar to our own. We can see that they share our commitment to maintaining a healthy, vibrant and collaborative culture.

·Until the transaction closes, which we currently expect to occur in Q2 2023, TCR2 and Adaptimmune remain separate companies operating independently as we have done before.

 

 

·It is important to stay focused on our day-to-day roles and responsibilities so that we can continue to treat cancer patients with gavo-cel and TC-510. They depend on us.

 

5.What does this mean for compensation and benefits programs?

 

·Adaptimmune has agreed that, for a period of 12 months following the merger or, if shorter, for such period each TCR2 employee remains employed with the combined entity, each TCR2 employee will be provided with a base salary and target annual cash incentive compensation opportunity and employee benefits (excluding any equity-based, change in control, defined benefit or retention benefits) no less favorable than are in effect immediately prior to the merger.

 

6.What does this mean for my equity awards in TCR2? Can I change my ESPP contributions between now and close?

 

·If you hold stock options, your options will be assumed by Adaptimmune such that they will be exercisable for American Depositary Shares (“ADSs”) or ordinary shares of Adaptimmune. In connection with this assumption, your stock option’s strike price and the number of ADSs or ordinary shares subject to your stock option will be equitably adjusted, with your stock option generally maintaining the same “spread” value as of immediately prior to the merger and having substantially similar terms and conditions.

·If you hold restricted stock units (“RSUs”), your RSUs will be assumed by Adaptimmune such that they will be settled in ADSs or ordinary shares of Adaptimmune. In connection with this assumption, the number of shares subject to your RSUs will be equitably adjusted and your RSUs will be converted into RSU-style stock options (with a nominal exercise price), but your new Adaptimmune RSUs will generally have the same value as your TCR2 RSUs as of immediately prior to the merger and will have substantially similar terms and conditions.

·If you currently participate in the TCR2 Employee Stock Purchase Plan (“ESPP”), you will not be able to increase your contributions and no new offering periods will be commenced. The current ESPP offering period will continue in effect as normal, except that if the merger closes before the last day of the current ESPP offering period, then the offering period will be shortened and end a few days before the merger. Any accumulated contributions made during that shorter offering period will be used to purchase TCR2 shares just before the merger. If you do not currently participate in the ESPP, you will not be able to begin participating in the ESPP.

 

7.What is an ADS?

 

·An “ADS” is an “American Depositary Share”.

·ADSs are a common method that non-US companies, like Adaptimmune, utilize in order to trade their shares in the US market.

·Each ADS is the economic equivalent of six ordinary shares of Adaptimmune and can be converted into ordinary shares of Adaptimmune. You can also convert ordinary shares into ADSs.

 

8.Should we anticipate any layoffs following the transaction?

 

·We understand this news may create anxiety about job security.

·While the ultimate decision will be up to Adaptimmune post-closing of the transaction, we have an opportunity in the coming weeks to influence the outcome and we are committed to being as transparent as possible during this process, and treating all employees with due respect.

·Until the transaction closes, which we currently expect to occur in Q2 2023, TCR2 and Adaptimmune remain separate companies operating independently and as we have done before.

·Remaining focused on your day-to-day responsibilities and remembering that we have many cancer patients depending on us is the best thing we can do.

 

9.Who will lead the combined company?

 

·Following the close of the transaction, the combined company will be led by Adrian Rawcliffe, the current CEO of Adaptimmune.

·Adrian is an industry veteran with over 20-years of experience in the biopharma industry, including at Adaptimmune and GSK, with a proven track record of driving innovation.

·Additional members of the leadership team are expected to be announced at a later time.

 

 

·Garry Menzel will be joining the Board of the combined company, along with two other directors from TCR2 to ensure continuity and representation of our many achievements.

 

10.Where will the combined company be located? Will any facilities be shut down?

 

·Until the transaction closes, both TCR2 and Adaptimmune will remain in their current locations and continue to do business as usual.

·Following the close of the transaction, the combined company will have a significant presence in the key United States cell therapy and innovation hubs of Philadelphia, PA, and Cambridge, MA, as well as Oxford/Stevenage in the United Kingdom. Many of you will have the opportunity to anchor that presence here in Kendall Square.

 

11.Will there be changes to reporting structures as a result of the transaction?

 

·Any such changes would occur following the transaction’s close, which is currently expected to occur in Q2 2023.

 

12.What will be the name of the combined business?

 

·Upon completion of the transaction, the company will be called Adaptimmune.

 

13.When will the transaction close?

 

·The merger is currently expected to close in Q2 2023, subject to approvals by Adaptimmune and TCR2 shareholders and other closing conditions.

 

14.What should I do if an employee of Adaptimmune contacts me with questions or requests for information?

 

·It is important to remember that until closing, TCR2 and Adaptimmune remain separate organizations, and we will operate as we have before.

·If you are approached by an Adaptimmune team member for any information about the integration, do not comment and refer them to Angela Justice at angela.justice@tcr2.com.

 

15.What does this announcement mean for business partners?

 

·The combination does not impact our relationships with our partners, and we are operating as we have before.

·We remain dedicated to working with our partners to support their needs and the needs of the cancer patients we serve.

 

16.Can I post on social media about this announcement?
