Poshmark All Employee Email from Naver CEO

From: SooYeon Choi, Naver CEO

To: All Poshmark Employees

Sent: October 5, 2022

Subject: Introduction to Naver

All,

It’s an honor to be reaching out to you today to share more about our industry-defining combination. I want to begin by letting you know that all of us at Naver have long admired the platform your team has built and grown over the last decade – it’s truly remarkable.

By now you’ve likely heard a little about Naver from Manish, but I wanted to take this opportunity to provide you with a little more background on us and share my excitement about the transaction and what we can do together to create a new, global C2C shopping experience.

Who is Naver?

We are Korea’s largest internet company and one of the country’s clear market leaders in both search and e-commerce, a unique dual strength that you won’t see elsewhere.

In Korea, Naver is the chosen platform for both searching and shopping. Our platform is home to approximately 530,000 smartstores – “sellers” – and generates more than 70% of online shopping searches in South Korea.

Our success in the Korean market is in large part due to our deep technology stack, which is something that we are excited to bring to Poshmark as we work together to capture the enormous market opportunities in our young and fast growing market.

Specifically, we have an established livestream shopping capability that is the leader in the Korean market.

While I know Poshmark has its own livestreaming feature, we believe that bringing the two together will accelerate the transformation of the shopping and selling experience by allowing for further social networking and engagement.

We are also excited to introduce our image recognition technology that helps users identify where to find and buy products by scanning objects and shopping through the camera on their phone.

This technology, along with some of our other innovative solutions, will make it easier to both identify new products and sell items, allowing us to take the Poshmark user experience to the next level.

Why Poshmark?

I have outlined some of the ways we hope to add value to the Poshmark platform, but importantly we are excited by how you can help us.

Poshmark is well known for its social marketplace and its loyal, highly engaged community, and while we have built our own communities, we know that Poshmark’s unique relationship-oriented “micro” community creates a more customized and personalized experience for its users.

One thing we particularly admire is Poshmark’s discovery-based platform, something that we do not currently have at Naver.

While there are many strategic benefits to bringing together our two companies, one of the most important attributes of this transaction is allowing our respective teams to do what we do so well – but with additional resources and greater market know-how.

This transaction is all about growth and enabling us to stay ahead of evolving consumer trends and expanding the e-commerce community globally by leveraging our international presence, sector expertise, and world-class technologies.

Importantly, one of the deciding factors in joining forces is our shared vision around global community commerce.

Through conversations with Manish, I have come to deeply admire the Poshmark platform, brand and company culture that all of you have built together, whether you have been here from the beginning or recently joined the company.

It is clear that Manish’s leadership since Day 1 has resulted in a collaborative, respectful company culture centered around building an industry leader in the re-commerce space – this is evident not only by your market-leading position, but also the amount of founding members that are still with the company today!

With all of this in mind, together, I am confident that we can redefine commerce and community around our shared vision and commitment to content, community and empowerment.

We also believe that the transaction will create new opportunities for our combined employees as we will have a larger global platform to invest in career opportunities and advance your ability to compete in the global marketplace, all while remaining true to our shared core beliefs and cultures.

I’m sure you have many questions, and Manish and I are committed to keeping you posted as we work to complete the transaction.

I look forward to meeting you in person soon and talking more about the incredible future that we will build together.

Best,

SooYeon Choi

Naver CEO

While the list of factors presented here is, and the list of factors presented in the Proxy Statement will be, considered representative, no such list should be considered to be a complete statement of all potential risks and uncertainties.
