Team,

Today is an exciting day as TI announced its agreement to acquire Silicon Labs.

Our team is familiar with Silicon Labs' wireless connectivity portfolio and has great respect for its position in the market. We've seen Silicon Labs' impressive ~15% compound annual revenue growth (CAGR) since 2014, and I am excited about the opportunity to bring our passion for innovation and engineering excellence together.

Demand for wireless connectivity products continues to grow as more devices get connected across more end equipments, and this announcement shows TI's commitment to accelerating progress in wireless connectivity. With Silicon Labs, we will enhance our leadership position in embedded wireless connectivity, building on the foundation set by our team. We'll have the opportunity to scale and sell more products, leveraging our unique manufacturing capabilities and an expanded wireless connectivity portfolio with additional protocols and security features, essential to support more customers and their designs.

As you likely read in Haviv's email, we will be able to welcome Silicon Labs employees to TI and work more closely together after the transaction closes, which we expect to occur in the first half of 2027, subject to required regulatory approvals and other customary closing conditions. There are no changes to how our team is structured or operates today. TI and Silicon Labs remain independent until closing.

Right now, we need to continue to act with urgency to achieve our 2026 must dos and execute our product roadmaps, as planned. Please stay focused on the work we have in front of us and put our customers first. Now is the time to accelerate our growth. I expect each of us to remain highly accountable as we work together to make this happen.

I will be available to answer questions about this announcement at our Connectivity Town Hall on Thursday, February 19. Our team has exciting opportunities ahead of us - I look forward to working alongside you all through this journey.

Subject: Strengthening our wireless connectivity position by acquiring Silicon Labs

I'm thrilled about the news today announcing our agreement to acquire Silicon Labs. Bringing together our two portfolios and teams accelerates the work we have been doing to strengthen our embedded processing business.

1 of 3

Together, we will be a leader in embedded wireless connectivity and have greater opportunities to win and expand our business. The addition of Silicon Labs' portfolio and expertise will enhance our technology, IPs and engineering skillset, scaling our capabilities in RF, mixed signal solutions and software. Our combined portfolio will allow us to provide more products that support a variety of wireless connectivity standards and protocols to our customers.

What's especially exciting about this transaction is the compelling growth potential. With more devices getting connected every day, growth in this market is outpacing the overall semiconductor market. Silicon Labs has developed a strong and diverse position in Industrial, where we know long-term secular content growth is happening.

I know you, like me, will be eager to start moving forward with Silicon Labs. We are at the beginning of this process, and there are many steps our teams will be working through before the transaction is completed. We expect the transaction to close in the first half of 2027, subject to required regulatory approvals and other customary closing conditions, and an integration team will be established to work through the details. In the meantime, product roadmaps will continue as planned, and both companies will operate independently until the transaction is completed.

We have a great opportunity in front of us, but we must stay focused on our 2026 must dos, mainly to grow. We've worked hard to strengthen our embedded processing business and now is the time to build upon our progress. I expect the team to act with urgency to accelerate revenue growth by converting pending to wins.

I will discuss this announcement in more detail at our Town Hall on Wednesday, February 11. I look forward to continuing this journey with each of you and am excited about the opportunities ahead.

Subject: TI to acquire Silicon Labs

TI Information - Selective Disclosure

I am pleased to announce that TI has signed a definitive agreement to acquire Silicon Labs.

This acquisition marks an exciting step in our journey to strengthen our embedded processing business - a journey many of you have been an important part of. Our efforts have improved our competitiveness and strengthened our embedded portfolio. Now is the right time to accelerate our progress with Silicon Labs and better serve our customers.

Silicon Labs and TI are a strong cultural and strategic fit. Together, we will create a global leader in embedded wireless connectivity, adding 1,200 Silicon Labs products that support a variety of wireless connectivity standards and protocols. We will be able to reshore Silicon Labs' manufacturing from external foundries and leverage our 300mm wafer fab manufacturing, including in Lehi, Utah, as well as our internal assembly and test capabilities. Our defined process technologies, including 28nm, are optimized for Silicon Labs' wireless connectivity portfolio. And we will be able to deepen customer engagements by utilizing our extensive sales channels to scale and sell more to our combined customer base.

Our teams share the same high-performing culture, values and ethical principles that define who we are and how we behave. We are both driven by our love of solving customer problems and delivering cutting-edge technologies. I have deep respect for Silicon Labs' technical expertise and talent, winning spirit and impressive results. They are the ideal addition to our team.

We will be able to welcome Silicon Labs employees to TI and work more closely together after the transaction closes, which we expect in the first half of 2027. In the meantime, there is no change to our operations - both companies will operate independently until the transaction is complete.
