EX-99.1

Exhibit 99.1

Dear Colleagues,

Moments ago, we announced an agreement under which ONO Pharmaceutical will acquire Deciphera Pharmaceuticals for $2.4 billion, or $25.60 per share, in cash. The full press release we issued is attached.

For the past 20 years, Deciphera has worked toward one mission, inspired by patients: to defeat cancer. As a team, we have made incredible progress on this journey – growing our revenue through QINLOCK and working to bring a potential new treatment to market in vimseltinib, all while advancing a robust pipeline of potential first-or-best in class potential medicines. We have much to be proud of.

While there is exciting momentum underway, we also know our journey is far from over. We believe today’s announcement will allow us to advance and accelerate our important work, with a company that shares our vision and our values. It is also a testament to your commitment and hard work.

Based in Osaka, Japan, ONO Pharmaceutical is a global healthcare company grounded in a mission to fight against human disease and pain, and with a proven history of innovative R&D in oncology, immunology and neurology and rare diseases. Their global business spans 5 countries, has over 3,700 valued employees, and 10 new drug candidates at the clinical stage of development. While our organizations may have different histories and expertise – we are aligned by a patient-centric ethos and commitment to innovation.

Not only are we culturally aligned, but we have highly complementary operations that will accelerate the growth and success of the combined organization. As we know well, Deciphera has specialized capabilities in kinase drug discovery, well-established commercial and sales platforms in the United States and Europe, and global clinical development capabilities. We also have a mature, diverse pipeline of best-or-first in class potential medicines. These attributes – including and particularly the talent and expertise of our team – will enable ONO to build a robust presence in oncology, one of its key priority areas. It will also reinforce ONO’s global development and sales capability, while expanding the potential for new innovation through the combined pipeline. The combination will support ONO’s efforts to become a Global Specialty Pharma company. Importantly, for all of us, as part of ONO we will be positioned to advance our work to bring QINLOCK and potentially vimseltinib to more people, sooner than we could as an independent company.

ONO recognizes and appreciates that the foundation of this company is you, and the expertise, passion, and experience you bring. I know that they look forward to welcoming us following the close of the transaction. I recognize that this is a change, and at times of change, it is natural to have questions about what this transaction means for you individually. We have scheduled an All Hands Meeting for today at 10:00 AM ET where we can talk in more detail and address some of your questions. I look forward to sharing more of my thoughts and feelings around this news when we get together. Smaller functional group meetings will follow the AHM. We have also attached an FAQ to this email to help answer some of your immediate questions. While we may not be able to answer every question at this early stage, we are committed to communicating openly with you as we have information to share.

Today is a milestone – but it is just the beginning of a process. There is much work to be done before we can close the transaction, which we expect to occur in the third quarter of 2024. I want to reiterate that until that time, Deciphera and ONO will remain two separate entities, and we will continue operating independently. As such, it is imperative that we continue business as usual during this time of transition. Nothing should change in our commitment to move our programs forward to deliver for patients as quickly as possible. All current goals and objectives remain the same. We are counting on all of you to help advance the important work we have underway.

This announcement is likely to generate increased interest in our company and it is important that we speak with one voice. If you receive inbounds inquiries from media, analysts, shareholders or others, please refer them to Jenn Larson (jlarson@deciphera.com).

Most of all, I would like to acknowledge your incredible work and steadfast commitment to transforming patients’ lives. On behalf of the Board of Directors and leadership team, I am grateful for each and every one of you and what you have done to advance our purpose.


Today’s news is a recognition of your tremendous work and validates what we have achieved at Deciphera. I am proud of what we have built together, and I hope that you are too.

I look forward to speaking to all of you soon.

Best,

Steve

Employee FAQ

 

1.

What was announced?

 

   

Deciphera has agreed to be acquired by ONO Pharmaceutical—a global healthcare company whose purpose is to fight against human disease and pain with focus areas in oncology, immunology, neurology and specialty – for $2.4 billion, or $25.60 per share in cash.

 

   

Together, ONO and Deciphera will accelerate our shared vision to deliver innovative new drugs and serve patients around the world.

 

   

Specifically, we expect to advance and accelerate each organizations’ important work through combined research and development capabilities and a global commercial footprint.

 

   

We also believe this transaction will enable us to bring QINLOCK and, if approved, vimseltinib to more people, sooner than we could as an independent company.

 

   

We are excited to move forward with a company that shares our vision and our values.

 

2.

Who is ONO?

 

   

Founded in 1717 in Osaka, Japan, ONO is a global healthcare company grounded in a mission to fight against human disease and pain.

 

   

ONO has an established track record of innovation across oncology, immunology and neurology and rare diseases – which includes the discovery of Opdivo, a human anti-PD-1 monoclonal antibody and the first PD-1 immune checkpoint inhibitor to receive regulatory approval anywhere in the world.

 

   

Their global business spans five countries, has over 3,700 valued employees, and 10 new drug candidates at the clinical stage of development. In fiscal year 2022, they recorded revenue of $3 billion.

 

   

Beginning in 2015, ONO embarked on a strategy to become a Global Specialty Pharma company, first by launching marketing operations in Taiwan and South Korea, and then launching both development and marketing operations in the U.S. and Europe.

 

   

Their acquisition of Deciphera is an important piece in advancing this strategy.

3. Why does this transaction make sense for Deciphera? Why now?

 

   

We believe that this transaction delivers for all of Deciphera’s stakeholders, including providing immediate, compelling value for our shareholders, greater opportunities for our world-class team, and ultimately, greater hope for patients.

 

   

We believe this transaction will allow us to advance and accelerate our important work, and make an even greater impact for patients, with a company that shares our vision and our values.

 

   

Our two companies had been engaged in discussions as like-minded industry partners, and in exploration of business opportunities. Through these conversations, we came to recognize that we share many of the same values and visions.

 

   

In particular, we each came to recognize that Deciphera could play an important role in advancing ONO’s strategy to become a Global Specialty Pharma company, and that by combining the strengths of our highly complementary organizations, we will be better positioned to accelerate our growth and deliver important new medicines to patients globally.

 

   

As we know well, Deciphera has specialized research and development capabilities in kinase drug discovery, well-established commercial and sales platforms in the United States and Europe, and global clinical development capabilities. We also have a mature, diverse pipeline of best-or-first in class potential medicines. These attributes—including and in particular the talent and expertise of our team—will enable ONO to build a robust presence in oncology, one of its key priority areas.

 

   

It will also reinforce ONO’s global development and sales capability, while expanding the potential for new innovation through the combined pipeline.

 

   

As part of ONO, we will be positioned to advance our work to bring QINLOCK and potentially vimseltinib to more people, sooner than we could as an independent company.

 

   

While we have exciting momentum underway, we also know our journey is far from over. As part of ONO, we will be part of a larger, diverse, global organization, with greater opportunity to grow and enhance our scale.


4.

Does ONO share Deciphera’s values?

 

   

Yes. While our organizations may have different histories and expertise – we are aligned by a patient-centric ethos and commitment to innovation.

 

   

Our two companies had been engaged in discussions as like-minded industry partners, and in exploration of business opportunities. Through our meetings and conversations, we came to recognize that we share many of the same values and visions.

 

   

In particular, ONO recognizes and appreciates that the foundation of this company is our world-class team. We are confident they will care for our people, pipeline and patients as much as we do.

 

5.

What does this mean for me? Is there anything that changes now?

 

   

We believe this transaction will allow us to advance and accelerate our important work, and make an even greater impact for patients, with a company that shares our vision and values.

 

   

While we have exciting momentum underway, we also know our journey is far from over. As part of ONO, we will be part of a larger, diverse, global organization, with greater opportunity to grow and enhance our scale.

 

   

The announcement of this transaction is just the beginning of a process. We expect the transaction to close in the third quarter of 2024 and, until that time, Deciphera and ONO will remain two separate entities, and we will continue operating independently.

 

   

It is imperative that we continue business as usual – moving our programs forward and advancing our pipeline to deliver for patients as quickly as possible. All of our current goals and objectives remain the same.

 

6.

What does this transaction mean for our patients?

 

   

As part of ONO, we will be positioned to advance our work to bring QINLOCK and potentially vimseltinib to more people, sooner than we could as an independent company.

 

   

But from a day-to-day perspective, we expect to continue to serve our patients in the same way we do now.

 

7.

Will ONO be involved in any decision-making before the deal closes?

 

   

We will continue to operate as a separate, independent company until the acquisition closes. However, we are subject to certain restrictions under the agreement with ONO. Please confer with your ET member for further instructions.

 

8.

With our 2024 budget/workforce planning process closed, how should we proceed with executing plan and budgets now?

 

   

We will continue to operate as a separate, independent company until the acquisition closes. However, we are subject to certain restrictions under the agreement with ONO. Please confer with your ET member for further instructions.

 

9.

What is a tender offer? What are the next steps in this process? How do I tender my shares?

 

   

A “tender offer” is a public bid for shareholders to sell their stock.

 

   

All Deciphera shareholders will be given an opportunity to “tender,” or sell, their stock for $25.60 per share within a specified timeframe.

 

   

In the same manner as Deciphera’s other shareholders, employee shareholders will receive information regarding the terms of the tender offer and instructions on how to tender their shares.

 

   

The closing of the tender offer is subject to the tender of shares representing a majority of Deciphera’s outstanding shares, receipt of applicable regulatory approvals and other customary conditions.

 

10.

When is the transaction expected to close?

 

   

The transaction is expected to close in the third quarter of 2024, subject to customary closing conditions, including U.S. antitrust clearance and the tender of a majority of Deciphera’s outstanding shares of common stock.

 

   

While we don’t yet have a specific date, we will keep you informed as appropriate, as we make progress toward the closing.


12.

Will there be any changes to leadership or reporting structures?

 

   

ONO’s intent is for our existing leadership team to continue to run the day-to-day of the business.

 

   

ONO recognizes and appreciates that the foundation of our company is our world-class team, and they look forward to welcoming us following the close of the transaction.

 

   

As you may expect, as we navigate how to best work together, there may be some operational or organizational changes following the close of the acquisition.

 

   

But fundamentally, we expect to continue operating much as we do today in terms of advancing our programs and strategic priorities.

 

   

We will keep you informed and updated as we move through the process.

 

14.

What will happen to Deciphera’s headquarters? Company name?

 

   

Deciphera will retain our headquarters in Waltham, Massachusetts, our offices in Europe, and our Research site in Kansas. There are no plans to change our company name at this time.

 

15.

Will my email address change?

Until the transaction is complete, it is business as usual, and you should continue to use your existing email.

 

16.

Will Deciphera still be a public company?

 

 

Deciphera will not be a public company after the transaction is completed.

 

17.

What should employees expect between now and closing?

 

   

Until the transaction closes, which we expect to occur in the third quarter of 2024, Deciphera and ONO remain separate and independent companies.

 

   

It is imperative that we continue business as usual during this time of transition.

 

   

Nothing should change in our commitment to move our programs forward to deliver for patients as quickly as possible, and all current goals and objectives remain the same.

 

   

Looking ahead, as we get closer to closing, some duties and responsibilities may vary in light of the pending transaction, including work to navigate how ONO and Deciphera can best work together in the future.

 

   

We will continue to keep you informed as we have updates to share.

 

18.

What should I say to partners or others who ask me about this transaction?

 

   

You can tell them that ONO values the patient community as much as we do and is committed to advancing care for people living with GIST, sarcomas, and TGCT.

 

   

You can remind them that until the transaction closes, Deciphera remains an independent company and we are continuing to work with them and support them as usual.

 

   

You can also let them know that looking ahead, upon completion of the transaction, Deciphera will operate as a standalone business of ONO.

 

   

We expect to operate much in the same way we do today in terms of advancing our programs and strategic priorities, and that we are focused on ensuring a seamless transition for them.

 

19.

Am I allowed to post about this transaction on my social media accounts, such as LinkedIn?

 

   

You may share Deciphera’s social posts from our official channels, but please do not add any commentary or share your own opinions.

 

   

Because of the nature of the transaction, only authorized leaders at Deciphera are permitted to discuss this news publicly, including on social media. If you receive inbounds inquiries from media, analysts, shareholders or others, please refer them to Jenn Larson (jlarson@deciphera.com).

 

20.

How does this transaction impact my pay and benefits?

 

   

Until the transaction closes, Deciphera and ONO remain separate companies, and we will continue to operate as such. This means that your pay and benefits are not impacted by this announcement.

 

   

Benefits are expected to continue unaffected during the pre-closing period. We will conduct our normal open-enrollment process in July and you will receive information regarding open enrollment shortly.

 

   

We expect our current benefits program to remain in place at least until open-enrollment in 2025.


21.

What will happen to my outstanding equity awards as a result of this transaction?

 

   

All unvested outstanding equity awards (including RSUs, PSUs, and stock options) will fully accelerate at closing.

 

   

All outstanding “in the money” stock options will be converted into the right to receive a cash payment equal to the difference between $25.60 per share and the strike price of the options. RSUs and PSUs will be converted into the right to receive a cash payment equal to $25.60 per share. Any stock options that are “under water” (grants where the strike price is equal to or greater than $25.60) will terminate at the close of this transaction.

 

   

This cash payment will be paid to you by ONO or Deciphera as soon as practical after the transaction closes, through your current payroll deposit method, subject to applicable withholding taxes.

 

   

More details on how equity will be treated as part of this transaction will be shared with employees in the coming weeks.

 

   

Please note that if you leave the company prior to the closing date, your unvested stock options, RSUs and PSUs will be immediately forfeited as of your termination date, and you will not receive any consideration with respect to these unvested awards.

 

22.

How will the deal impact the Deciphera ESPP?

 

   

The current Deciphera ESPP offering period will end on May 15 and no future ESPP periods will commence.

 

   

At the end of the current offering period, your accumulated contributions under the ESPP will be used to purchase shares of common stock in accordance with ESPP. Shares of common stock acquired under the ESPP shares will then be cashed out like other shares of common stock in the transaction. Any cash contributions to the ESPP that were not used in connection with the final option exercise will be returned to you.

 

   

The current Deciphera ESPP offering period will also be the last offering under Deciphera’s ESPP, which will then be terminated in connection with the transaction.

 

23.

Will I be restricted from trading in Deciphera stock while the transaction is pending?

 

   

Trading will be subject to our current standard practice of pre-clearance and blackout.

 

24.

What do I do if I am contacted by a member of the media, an analyst or shareholder about the transaction?

 

   

It is important that we speak with one voice. Only designated company spokespersons are permitted to speak with these market participants.

 

   

If you receive any external inquiries or are approached about the transaction (including from analysts, shareholders, or media), please direct them to Jenn Larson (jlarson@deciphera.com).

Exhibit 99.3

Subject: Deciphera Pharmaceuticals to be Acquired by ONO Pharmaceutical

Good morning,

I’m reaching out to make sure you saw the announcement that Deciphera has entered into a definitive agreement to be acquired by ONO Pharmaceutical, a global healthcare company grounded in a mission to fight against human disease and pain, and with a centuries-long track record of drug development.

Under the terms of the agreement, ONO will acquire all outstanding shares of Deciphera common stock for $25.60 per share in cash for a total equity value of approximately $2.4 billion.

ONO is based in Osaka, Japan and listed on the Tokyo Stock Exchange, which is closed today in observance of a holiday. An announcement from ONO will be forthcoming when the Tokyo Stock Exchange reopens tomorrow.

In light of the transaction, Deciphera will not be hosting a Q1 2024 earnings call. The Company will file a form 10-Q in the ordinary course.

Thank you, as always, for your support of Deciphera.

Sincerely,

INSERT NAME, TITLE

Exhibit 99.4

Dear Valued Partner,

I’m reaching out to share some exciting news about Deciphera – we have reached an agreement to be acquired by ONO Pharmaceutical, a global healthcare company dedicated to the fight against disease and pain. This combination marks the beginning of an exciting next chapter for Deciphera, one that we believe will advance our work to bring important medicines to more people, sooner than we could as an independent company. You can learn more about our announcement here.

By combining the highly complementary strengths of our two organizations, we will accelerate our shared vision to deliver innovative new drugs and serve patients around the world. As you know, Deciphera has specialized capabilities in kinase drug discovery, well-established commercial and sales platforms in the United States and Europe, and global clinical development capabilities. We also have a mature, diverse pipeline of best-or-first in class potential medicines. These attributes will enable ONO to build a robust presence in oncology, one of its key priority areas, while also expanding the potential for new innovation through the combined pipeline. We look forward to being an even stronger partner for you as part of a larger, diverse, global organization.

While today’s announcement represents an important milestone for our company, it is only the first step in our work to become part of ONO. Deciphera and ONO will continue to operate as independent companies until the close of the transaction, which we expect to occur in the third quarter of 2024. This means it is business as usual for all of us. There are no changes to the way we work with you. As appropriate, we will continue to keep you informed of any information relevant to you as we move toward closing the combination. If you have any questions, please don’t hesitate to reach out to INSERT NAME, TITLE.

On behalf of our entire team, I’d like to thank you for your continued partnership and trust in Deciphera. We are excited to embark on this next chapter and look forward to continuing to work with you for the betterment of patients around the world.

Sincerely,
