Letter to Senior Leaders

Dear colleagues,

Earlier today I spoke at Alcatel-Lucent’s Annual Leadership Meeting and wanted to share with you the key points of my speech. This is the first time that I have addressed their leadership team directly and was pleased to have the opportunity to convey our ambition for the combined company to them.

To set the scene, I shared with them my view of the market trends that create the stage on which we will operate in the coming years. This includes the extraordinary acceleration of technology, and the many challenges and opportunities facing operators; how these come together and what they mean for our long-term vision of enabling the human possibilities of the connected world.

As you know, vision is no good without strategy and, while it is too early to talk about the strategy of the combined company in detail, I can say now that we will be guided by three strategic aspirations – to lead, to grow and to innovate.

We want to be the leading partner for operators. We want to deliver fast growth from adjacent businesses. We want to be a powerhouse of innovation with Nokia’s FutureWorks and Alcatel-Lucent’s Bell Labs, as well as Nokia Technologies which will stay as a separate entity with a clear focus on licensing and the incubation of new technologies. With these extraordinary assets, we can shape the industry in disruptive ways and monetize the intellectual property that we create to build predictable, high-margin revenue streams.

I know both you and our colleagues within Nokia, much like the employees of Alcatel-Lucent, are curious to hear what comes next in terms of the combined company’s operating model, organizational structure and leadership. I’m sure you will agree with me that it is critical that we both get it right and do it right.

This means the right design and the right leadership, with selection based on pure merit, not nationality, predecessor company, politics or anything else. I am currently in the process of selecting the future leaders for the new Nokia and working to make final decisions on our high-level structure. These plans are subject to approval, and I hope that we are able to have both those top-level nominations and the target operating model design in place for a Board meeting at the end of September. Once approved, we will share them with you at some point in October.

One of the other areas I spoke about today was our integration planning. Here, our guiding principles are simple:

Letter to Senior Leaders

The first “container” is Nokia Technologies, which will continue on its current path of incubation and licensing of new technologies. We will protect its independence and target new areas for growth, typically outside the world of networks infrastructure.

We plan to have four further “containers” derived from the current Nokia Networks and Alcatel-Lucent businesses:

Mobile Networks, where we plan to place a premium on scale and efficiency, and ongoing cost improvement, all under-pinned by a strong focus on quality.

Advanced Analytics and Applications is planned to cover things like the cloud layer, IoT, virtualization, security and more. This needs to be managed in a way to nurture new opportunities and build multi-billion euro business opportunities for us for the future.

In Ultra-Broadband, extreme efficiency with selective investment in growth opportunities will be the order of the day and, finally, IP Networks where we need to invest in growth and scale, and incubate the technologies of the future.

I’d like to finish this note by providing you with a little further insight into our ambition for the combined company, just as I did with Alcatel-Lucent’s leaders.

Both Nokia and Alcatel-Lucent have storied pasts. However, I firmly believe that their best days are still to come in a future of opportunity, a future of possibility, a future of innovation and excitement.

This will not be an easy task but it is one that I know we can achieve. Together, we can create a company that is not content to be just the best in our industry; rather, we should aim to be the best of all companies. This is our challenge. I am incredibly excited to share it with you and our future colleagues today.

I will hold a follow-up call in the near future with those who receive this email to update on progress and take any questions you may have.

Best,

Rajeev
