Exhibit 99.2

Bristol-Myers Squibb Acquisition of MyoKardia – Internal FAQs

General

What was announced?

Bristol-Myers Squibb and MyoKardia announced a definitive agreement under which Bristol-Myers Squibb will acquire MyoKardia for $13.1 billion, or $225.00 per share in cash. The transaction was unanimously approved by both the Bristol-Myers Squibb and MyoKardia Boards of Directors and is currently anticipated to close during the fourth quarter of 2020.

What are the terms of the transaction?

Under the terms of the merger agreement, a subsidiary of Bristol-Myers Squibb will promptly commence a tender offer to acquire all of the outstanding shares of MyoKardia’s common stock. MyoKardia’s Board of Directors unanimously recommends that MyoKardia’s shareholders tender their shares in the tender offer.

The transaction is subject to customary closing conditions, including the tender of a majority of the outstanding shares of MyoKardia’s common stock and antitrust approval. Following the successful closing of the tender offer, Bristol-Myers Squibb will acquire any shares of MyoKardia that are not tendered into the tender offer through a second-step merger at the same price of $225.00 per share in cash.

Why did we decide to proceed with a transaction with Bristol-Myers Squibb?

In short, our Board determined that Bristol-Myers Squibb’s offer provides compelling value to all stakeholders: our shareholders, our employees, and the people that we serve. We believe that a combination with Bristol-Myers Squibb will allow us to serve more patients around the world faster than we would have done by ourselves, and the offer price rewards our investors for their support of our mission.

A company like ours is attractive to a company like Bristol-Myers Squibb because we built it with a long-term vision and a bold, innovative strategy. The promise for cardiovascular patients from what we’ve built here at MyoKardia can be accelerated, super-charged even, by the resources and capabilities a company like Bristol-Myers Squibb can offer.

When Bristol-Myers Squibb approached us, we could see that they have a vision that matches our own – to transform patients’ lives through bold and innovative science. Bristol-Myers Squibb has a deep history in cardiovascular medicine and a strong track record with CV patients. Their interest includes, but extends far beyond, mavacamten. Bristol-Myers Squibb understands the value of our entire pipeline, and more importantly, of our highly skilled people, our culture and the way we do business.

What do we know about Bristol-Myers Squibb?

Bristol-Myers Squibb’s mission (To discover, develop and deliver innovative medicines that help patients prevail over serious diseases) is highly compatible with ours. Take a look at their website. You’ll see they share our patients-first mindset, our passion for thoughtful and data-driven science, our commitment to diversity (in their workforce, in clinical trials, in suppliers and in their community programs), as well as a strong company culture with a succeed together mindset. As part of this process, we’ve gotten to know their team and have been really impressed with them and by how much they value the expertise we bring. They are interested in maintaining a strong west coast presence and have a lot of excitement for MyoKardia’s people and our pipeline.

To whom should I refer press inquiries?

All inquiries should be referred to Michelle Corral.

Where should I go if I have questions?

Please send questions to eccommunications@MyoKardia.com and there are FAQs on MyoSphere, which contain the available information to date. We will also have frequent Q&A sessions and other touchpoints with EC. You can also talk with your manager and HRBP.

You can also take advantage of our Employee Assistance Program and/or reimbursement for online therapy (i.e. Talkspace) if you would like help managing through this period of ambiguity.

Employment

Will there be layoffs? If yes, when will we know?

We continue to operate as separate companies until the deal is closed, which is expected later this year. Taylor and Jake will take the lead on transition planning from our team, and Bristol-Myers Squibb has identified a transition lead as well. As those plans materialize, we anticipate that both retention packages and severance plans will be announced.

Our people, culture and unique precision medicine approach are large parts of what attracted Bristol-Myers Squibb to MyoKardia. Bristol-Myers Squibb has already demonstrated the value it places on our team through a few actions as part of the merger agreement, including immediate cash-out of all time-based employee equity at close, as well as guaranteed payout of the 2020 bonus at 150% of target cash compensation. We also worked together to ensure that should roles be eliminated, affected employees will receive a minimum of six months of base salary plus a pro rata portion of their target bonus, in addition to COBRA and outplacement services. Bristol-Myers Squibb has robust retention plans in mind and we have comprehensive severance plans in place.

We will share information as it becomes available. In the meantime, we encourage everyone to maintain momentum on delivering on our commitments to patients.

What will happen to my compensation?

For retained employees, Bristol-Myers Squibb will maintain your existing cash compensation levels for 12 months following the closing (or until January 1, 2022, at the latest).

What will happen with my health care and other benefits?

The transaction is yet to close and during that time, we are an independent company and your benefits package stays intact. Given that open enrollment is coming up soon, we will work closely with Bristol-Myers Squibb to determine the best path forward for our employees in terms of planning for 2021 benefits enrollment. Please watch for more information on that.

Bristol-Myers Squibb has a very comprehensive total rewards package and they appear on the Working Mother, Working Dads, Disability Inclusion, and Best Places for LGBTQ lists. They have an impressive set of Diversity, Equity and Inclusion programs including workforce representation, but also extending to health iniquities, clinical trial design, supplier diversity and more. They seem to really act on their commitments. Their HR folks are working on ways to provide you with information, possibly even before the deal closes.

Operations

Should we stop working on projects in progress? How will this affect annual planning cycles such as budget and performance management?

This is a critical time for our company and we must maintain momentum for patients and for each other. We are committed to operating in the ordinary course during this time. Please continue to push forward with your work. As usual, please work with your manager if you have questions.

Employee Disbursements

When the transaction closes, what will happen to my outstanding equity awards?

This cash amount will be subject to the same vesting conditions as applied to the related PSU award, and if and when these vesting conditions are satisfied, the related amount will be paid as promptly as practicable thereafter, through either direct deposit or a check, in accordance with your current payroll deposit method, subject to applicable withholding taxes.
