Ionis Employee FAQ

 

 

1.

What was announced?

 

   

We announced that Ionis and Akcea have entered into a definitive agreement under which Ionis will acquire all of the outstanding shares of Akcea common stock it does not already own, approximately 24%.

 

   

This is another step forward in Ionis’ evolution and creates a stronger, more efficient organization to the benefit of all stakeholders.

 

   

We believe this transaction will ideally position Ionis to drive forward our vision and most effectively deliver our medicines to the patients who are depending on us.

 

2.

Why is Ionis acquiring Akcea? How does this transaction fit into Ionis’ strategy?

 

   

We believe there is significant strategic value in becoming one company – with one vision and one set of strategic priorities, led by one team.

 

   

Since the founding of Akcea in 2015, and since its IPO in 2017, in close collaboration with Ionis, Akcea has launched Tegsedi globally and Waylivra in the EU, while advancing a late-stage pipeline and securing important partnerships. Over that same period, Ionis has evolved significantly. This is the right transaction at the right time.

 

   

This is another step toward building Ionis’ commercial strategy for the future.

 

   

We believe completing this transaction now enhances the future success of our company and accelerates our next phase of growth.

 

   

This transaction also further strengthens Ionis’ financial position.

 

3.

When will the transaction be completed and what can employees expect between now and then?

 

   

The transaction is expected to close in the fourth quarter of 2020, subject to customary closing conditions.

 

   

Until then, Ionis and Akcea will continue to operate as we have and it is business as usual.

 

4.

What does this mean for Ionis employees?

 

   

In creating a stronger, more efficient organization, this transaction will benefit all of our stakeholders, including our employees.

 

   

Until the transaction closes, which we expect in the fourth quarter of 2020, Ionis and Akcea will continue to operate as we have and it is business as usual.

 

   

Given how closely we work with Akcea on a day-to-day basis, we expect there will be minimal disruption.

 

   

For those who will be working on the team to further refine our long-term planning, we appreciate your support.

 

5.

Will there be layoffs of Ionis employees?

 

   

No. This transaction will not impact Ionis personnel.

 

6.

How will Akcea employees be integrated into the Ionis organization?

 

   

It is still early in the process, and there are many decisions that have yet to be made.

 

   

A team will be formed this week with representatives from both companies to determine how best to bring these two organizations together.

 

   

Between now and close, that team will work together to further refine our long-term planning.

 

   

We are committed to communicating transparently with you as decisions are made.


Page 2 of 3

 

7.

What does this transaction mean for patients?

 

   

We believe this transaction will position Ionis to most effectively deliver medicines to the patients who are depending on us.

 

   

As a stronger, more efficient organization, we will be even better positioned to deliver on the more than 10 marketing applications expected through 2025, which could potentially result in numerous new commercial medicines.

 

   

We will have the financial strength to increase investments in Ionis’ pipeline, technology and commercial capabilities, and invest in complementary and/or disruptive technologies that will continue to broaden our reach.

 

   

This is another step toward building Ionis’ commercial strategy for the future.

 

8.

Can we discuss this news with Akcea employees?

 

   

You should continue to partner with Akcea employees as you have historically. Please do not contact Akcea employees you do not typically partner with on day-to-day responsibilities until the transaction closes. Please be sensitive to the impact of your communications with any Akcea employee.

 

9.

What do I do if a shareholder, analyst or member of the media contacts me?

 

   

Please note that, except for certain company executives, Ionis employees are not authorized to speak publicly or communicate externally about this announcement, including on social media channels.

 

   

To that end, if you receive any inquiries from investors or analysts, please refer them to Wade. Inquiries from the media or other outside parties should be referred to Roslyn.

 

10.

Who do I contact with questions? Where can I go for more information?

 

   

Please reach out to your manager with any questions. We will keep you informed as we move forward.

Ionis Investor Talking Points

 

What We Announced

 

   

Ionis reached an agreement with Akcea to acquire the outstanding shares of Akcea common stock we do not already own, approximately 24%, for $18.15 per share in cash.

 

   

This corresponds to a total transaction value of approximately $500 million on a fully diluted basis.

 

   

We expect to fund the acquisition through existing cash resources. The transaction is not subject to any financing condition.

Strategic and Financial Benefits

 

   

This is another step forward in Ionis’ evolution and creates a stronger, more efficient organization.

 

   

This is another step toward our building Ionis’ commercial strategy for the future.

 

   

We believe there is significant strategic value in becoming one company – with one vision and one set of strategic priorities, led by one team.

 

   

Since the founding of Akcea in 2015, and since its IPO in 2017, in close collaboration with Ionis, Akcea has launched Tegsedi globally and Waylivra in the EU, while advancing a late-stage pipeline and securing important partnerships.

 

   

Over that same period, Ionis has evolved significantly.

 

   

Our technology has been proven and validated.

 

   

Our deep, broad, diverse pipeline of more than 40 potentially transformative medicines has advanced with more than 25 mid- to late-stage programs; and has delivered three commercial products, including the blockbuster Spinraza.

 

   

Ionis’ culture of innovation is deeply embedded throughout the organization and continues to thrive.

 

   

And our financial position is even stronger today.

 

   

We believe this transaction will enhance the future success of our company and accelerate our next phase of growth.

 

   

Ionis will also further strengthen its financial position through this transaction …

 

   

…by realizing more financial upside from Akcea’s rich pipeline and commercial products.

 

   

…by gaining full access to Akcea’s significant cash on hand of approximately $390 million as of June 30, 2020 and future cash flows to further invest in Ionis’ future and further support Ionis’ capital allocation strategy.

 

   

…by achieving meaningful cost synergies.

 

   

This is the right transaction at the right time and ideally positions Ionis for the future.

Next Steps

 

   

Under the terms of the agreement, Ionis will commence a tender offer for all outstanding shares of Akcea common stock not already owned by Ionis at a price of $18.15 per share in cash.

 

   

The closing of the tender offer will be subject to a majority of Akcea’s shares not already owned by Ionis, its affiliates or their respective directors and executive officers being tendered in the tender offer.

Page 2 of 2

 

   

Promptly following the completion of the tender offer, Ionis will acquire all remaining shares of Akcea common stock at the same price of $18.15 per share in cash through a second-step merger.

 

   

We expect to complete the transaction in the fourth quarter of 2020.


Closing

 

   

Thank you again for taking the time to speak with us today.

 

   

As always, and as you know, we are committed to open communication with our shareholders, so we’ll keep you apprised of any significant developments.

 

   

I’d be happy to take your questions…

Exhibit 99.4

Ionis bpm Update Transcript

 

Good morning everyone and happy Monday.

I’m reaching out to you this morning to share some very exciting news.

We just announced today that we’ve reached an agreement with Akcea to acquire the outstanding shares of Akcea common stock, the remaining shares that we do not own already, approximately 24%.

This step is yet another step forward in the evolution of Ionis, a step forward that creates a stronger, more efficient organization to the benefit of all stakeholders.

Over the past few years, Ionis and Akcea have grown and evolved significantly. We believe at this time there is significant strategic value in becoming one company – with one vision and one set of strategic priorities, led by one team.

We believe this transaction will greatly enhance the future success of Ionis and accelerate our next phase of growth. By creating an even stronger financial foundation, with the retention of more value from Akcea’s rich pipeline and commercial products, which this transaction will do, Ionis will be ideally positioned to drive forward our vision to lead in the delivery of transformational medicines to the patients that depend on us.

Given how closely we work with Akcea on a day-to-day basis, we expect this to be a seamless transition with minimal disruption.

Until the transaction closes, which we expect to happen in the fourth quarter of this year, Ionis and Akcea will continue to operate as we have, that is to operate business as usual.

I am looking forward to discussing this transaction with you further at an All-Employee Meeting soon, sometime in September. In the meantime, I encourage you to speak with your area Vice President if you have questions.

Thanks, as always, for your hard work, your commitment to Ionis and to the patients we serve. And thanks for listening. More coming soon, but that’s all for now.
