INTERNAL EMAIL ANNOUNCEMENT

Team,

We are thrilled to share today that Planet is going public! We are doing this via a merger with a special purpose acquisition company (also known as a SPAC). This is the first step in a process through which Planet is expected to become a publicly listed company later this year.

In 2010, we founded Planet with a vision to use space to help life on Earth. We turned this vision into a mission to do something that had never been done before —to image the earth daily and make change visible, accessible and actionable—a mission that is alive and well. Going public is our next step on the path to realizing it, and will accelerate it by empowering us with the resources to scale our business and our impact.

We’ve come a long way and are so proud of all that this company and our team have achieved. From building a world-class satellite manufacturing and space operations capability to achieving the daily revisit to architecting the first cloud-native geospatial data pipeline to creating a scalable >$100m/year business, Planet is really several innovative and consequential companies rolled into one pioneering organization. We have built something truly unique that is driving critical value to customers, having a positive impact on real-world problems.

We should all be incredibly proud of reaching this milestone. This has been made possible through the tremendous dedication and hard work of Planeteers. Thank you for your tireless effort and commitment to Planet and our mission.

And there’s an important backdrop for Planet: the world’s ecosystems and climate are at a critical juncture and humanity needs to change fast to avert a crisis. We are also experiencing a wave of threats to international peace and security, and an era of disinformation. We believe that the world desperately needs Planet’s data to help fight these challenges by illuminating the most important forms of environmental and social change. Planet—via our customers—is already helping to solve these challenges, but this is the tip of the iceberg of our potential; there are millions of people and organizations who could benefit from our data.

What Does this Mean?

Going public will provide us with significant opportunities to drive growth in our business. We mentioned that Planet will be merging with a company named dMY Technology Group, Inc. IV – dMY IV is a SPAC that is already listed on the NYSE. A SPAC doesn’t have any operations itself and is formed to find an operating business like ours, combine with it, and use funds raised from issuing stock to help accelerate growth. We chose dMY IV because they believe in Planet’s vision and see our full potential: as a data and analytics company that empowers myriad users, from governments to companies to NGOs, to make smarter decisions. They want to enable Planet’s mission and they are huge fans of how Planet can power the transition to a sustainable economy.

dMY IV has proven experience supporting the growth of pioneering companies across the technology industry. In fact, Planet will be the fourth company they have taken public. They are led by Niccolo de Masi and Harry You, seasoned executives and operators who we’re thrilled to be working with.

Why Go Public?

In short, acceleration. As a public company, Planet will be better able to expand into new verticals and further develop our products and solutions. We plan to scale sales and marketing to capture opportunities in our key markets and in new ones. We will work to build our software stack toward delivering insights and solutions customers need. We’ll be better equipped to build new sensors and add more data to our growing archive and real-time data feeds, continuously advancing our products to solve more complex problems for our customers. We’ll be better known as a public company with an increased level of brand exposure. Our customers will be more confident in relying on us for the critical services because they know that Planet is an established public company.

There are downsides, too. There will be volatility as Planet’s stock goes up and down, sometimes totally unrelated to anything we do. We won’t be able to talk as freely about our plans, given legal restrictions on public companies. We will also feel quarterly pressure to hit targets, making it important to stay focused on our long term goals.

The leadership team and the Board have carefully weighed these considerations and we’re absolutely convinced this is the right decision and that it will accelerate Planet toward its goals.

Why Now?

In short, Planet is ready for the world and the world needs Planet.

We’re doing this now because Planet is ready and there is momentum in the market. We have a growing business serving a variety of diverse vertical markets and we know the world is ready for Planet. As the global economy reboots out of the pandemic, there is a strong push to boot back into a sustainable economy. We believe Planet’s data has a mission-critical role in the global sustainability transition. This switch accelerated in 2020, driving increased demand for Planet’s data.

Will we keep Planet’s Mission?

Planet’s vision and mission are not changing. In fact, they are being strengthened because Planet will go public as a Public Benefit Corporation (PBC). We’ll share more on what this means later, but the key point is that as a PBC Planet’s mission will be encoded into its corporate DNA, obligating the directors to stay true to our mission. Further, we, the founders, will retain voting control of Planet so the company stays mission-aligned.

We are committed to the long term goal of ensuring a sustainable and secure planet where life flourishes. In 10 years, we envision Planet as a leading global business whose data and services power every business and government use to make smarter decisions, whether enabling digital transformation or sustainability; in short we see Planet as a cornerstone of a global economy that accounts for natural capital. It’s never been more clear to us that Planet’s vision to use space to help life on Earth is directly connected to our ability to build a commercially successful business, driving a virtuous cycle where Planet’s success as a business results in a healthier planet.

Next Steps

Today’s announcement is the first step in this process and the transaction is expected to close later this year. We will continue to operate as we do now and there will be no changes to daily work.

We know this is exciting, but we must remain focused on delivering great products and solutions for our customers. We should also remember that it’s only one milestone: the world’s best companies are defined not by going public, but by what they achieve in the years thereafter.

To celebrate and answer questions, we will gather everyone at the All Hands meeting later today (normal slot, 8am PST, but extended to 45 minutes). While this transaction doesn’t change our focus now or in the future, we’d like to take some time to discuss the news with you in more detail. There is a FAQ attached to this email with more information on the transaction and what it means for you. While we may not have all the answers to your questions right now, we will keep you informed as we navigate through this process. In addition, you can submit your additional questions here [LINK]. We will have an AMA this Friday to address your pre-submitted questions. Please note this session won’t be recorded so please plan to attend live. We will add further sessions, as needed, depending on volume of questions we get over the next few weeks.

This announcement may generate interest from the media, analysts, or other third parties who may contact you looking for comment or additional information. If anyone from outside Planet contacts you, please do not respond and direct any inquiries to Trevor Hammond at Comms@planet.com.

Thank you all for your hard work and passion. Every Planeteer’s dedication to our mission over the years has played a part in getting us to this key milestone. Together, we have built something remarkable at Planet. It’s the tip of the iceberg of Planet’s potential and this milestone helps us continue to build. We look forward to the next decade of Planet’s future together.

Ad astra!
