Dear Talkspace Team,

We are excited to announce that this morning, we signed an agreement to partner with Hudson Executive Investment Corp. (HEIC) and become a publicly traded company on NASDAQ. This is a very exciting development that we expect to be completed in the first half of 2021, and the next step in our journey. The transaction also values Talkspace at $1.4 billion, which is an incredible achievement we should all be proud of. HEIC will be a tremendous partner for us, with very deep experience in healthcare and innovation. Here is a link to the press release we issued this morning to learn more about the agreement and about HEIC.

HEIC is a special purpose acquisition company (SPAC) that is publicly traded on NASDAQ. The nature of the transaction is a merger, where we will combine with HEIC and then trade publicly under the new ticker symbol “TALK”. As a SPAC, HEIC was created in June of 2020 for the purpose of merging with a promising, high-growth company like us. It is not an operating company, but rather a pool of capital intended for this acquisition alone. After this transaction is complete, we will still be the same Talkspace—our team, how we do business, and our business model will remain completely unchanged. The exciting new development is that we will have the resources, network and deep experience of the HEIC team as a valued partner.

HEIC is an ideal partner to bring Talkspace public, accelerate our growth, and further advance our mission. It is a premier investment firm led by Doug Braunstein, a former JP Morgan Chase Vice Chair and CFO with deep experience in healthcare tech. Their investors also form a network of CEOs and former CEOs of some of the best healthcare and managed care companies in the world.

This is an extraordinary achievement for us all, and one we could not have reached without the incredible work and dedication of our entire team. When this transaction is complete, I’m proud to say we will be the first publicly traded pure-play virtual behavioral healthcare company. This is a milestone worth celebrating, and we want to recognize every one of your contributions that has brought us so far together. We aren’t a startup anymore—we’re a true industry leader setting the pace for better care for more people, with the capital and support to make our shared vision real.

As the country grapples with the COVID-19 pandemic, an economic recession, and social unrest, the work that you do is making a difference for so many. I am so proud of the impact we have made in providing enhanced access, outcomes and pricing for mental health. Roni and I can’t overstate how deeply grateful we are to you, and to everyone that has been a part of the Talkspace journey thus far.

I also want to mention a few things we need to consider given this news. First, please refrain from making any statements about this news in any public forums until our all-hands meeting later this morning. At that time, we’ll provide you with materials that you can post on social media to share the good news with all your family and friends. The Securities Exchange Commission (SEC) has strict guidelines governing publicly-traded companies, which means we must avoid speaking publicly about this process, our business metrics, and financial information unless you are authorized to do so. At the end of this email is a list of legal “do’s and don’ts” that we must all follow in connection with this transaction. Please familiarize yourself with these guidelines.

Going forward, if someone asks you about the process of going public, the best response is to be polite and brief, saying, “We’re really proud and excited, but I’m not authorized to say more about it.” If pushed further, you can say something like, “I can’t speak to that, but I would be happy to connect you with a colleague who can.”

We’ll be discussing this transaction during our all hands at 10:00 AM ET today, so please be sure to tune in. In the meantime, please do not share this communication or information outside of this group.

Should you receive any press inquiries, please forward details to our Director of Communications, JoAnna DiTullio, and she will route media requests appropriately during this sensitive time.

It is an exciting time for all of us at Talkspace and I wish we were all together to celebrate in person!

Thank you,



Our business agreement to merge with Hudson Executive Investment Corp. (HEIC) is just a first step in the process of us becoming a publicly traded company. While it’s just the beginning, it does mean that we must now comply with certain Securities and Exchange Commission (SEC) regulations. The SEC strictly regulates what can be disclosed internally and also what can be said to the press and to people outside of Talkspace about the status of our announcement. Below are a set of dos and don’ts related to the announcement:



DO conduct business as usual. We urge everyone to stay focused on our business objectives and on continuing to serve our customers.



HEIC and Talkspace will be making various public statements and HEIC will make a number of securities filings. These will be covered by the media. DON’T comment, editorialize, or provide additional context for the information that is publicly disclosed in verbal conversation, emails and other online forums such as social media. For example, do not “like”, re-tweet or post articles that include this information.



DO refer (without comment) all media, press or other external communications requests and inquiries to [XXX]@talkspace.com.



In response to any questions you may receive via email, phone or in person from any third party—including customers, business partners, vendors/suppliers, industry analysts, consultants, market research firms, former employees, friends or family, etc. DON’T say any more than “I cannot comment. The latest information can be found in public filings and on our company website.”



DON’T speculate about the timing for the closing of the transaction or if it will be successful, our financial results, product/service launches (unless specifically authorized to do so).



DON’T buy any securities of HEIC (currently traded on Nasdaq).



DON’T recommend that anyone else buy any of the securities of HEIC (which currently trade on Nasdaq) if you have any material non-public information (“Non-Public Information”) about either HEIC or about Talkspace. Everyone at Talkspace is likely aware of some form of Non-Public Information, so it’s best to steer clear of buying or recommending someone buy HEIC securities.



Non-Public Information is information that an investor would consider important in deciding whether to buy securities of HEIC. Non-Public Information could include information about our financial performance, the likelihood of being able to close on the merger, new product/service offerings, developments regarding key suppliers or customers, our future plans, significant cyber security incidents, etc.



DON’T provide Non-Public Information to any third parties (including family members, friends, customers, partners, vendors/suppliers, etc.) so that they can then buy any of the securities of HEIC.



For managers, when communicating Non-Public Information to others within the Company, DO make sure that it is a business necessity to disclose such information to the person. If not, during this stage of the process DONT disclose the information.



DO email [XXX]@talkspace.com if you have questions about your responsibilities.
