Biogen Inc.

Please stand by, we are about to begin. Good morning, my name is Allie and I will be your conference operator today. At this time, I would like to welcome everyone to the Biogen third quarter 2023 earnings call and business update. All lines have been placed on mute to prevent any background noise. After the speaker's remarks, there will be a question and answer session. If you would like to ask a question during this time, simply press star one on your telephone keypad. Please limit yourself to one question to allow other participants time for questions. If you require any further follow-up, you may press star one again to rejoin the queue. Today's conference is being recorded. Thank you. I would now like to turn the conference over to Mr. Chuck Triano, Head of Investor Relations. Mr. Triano, you may begin your conference.

Thank you, Allie. Good morning, and welcome to Biogen's third quarter 2023 earnings call. Before we begin, I'll remind you that the earnings release and related financial tables, including our GAAP financial measures and a reconciliation of the GAAP to non-GAAP financial measures that we will discuss today are located in the investors section of Biogen.com. Our GAAP financials are provided in Tables 1 and 2, and Table 4 includes a reconciliation of our GAAP to non-GAAP financial results. We believe non-GAAP financial results better represent the ongoing economics of our business and reflect how we manage the business internally. We have also posted slides on our website that follow the discussion related to this call. I'd like to point out that we will be making forward-looking statements which are based on our expectations. These statements are subject to certain risks and uncertainties, and our actual results may differ materially. I encourage you to consult the risk factors discussed in our SEC filings for additional detail. So, on today's call, I am joined by our President and Chief Executive Officer, Chris Biebacher, Dr. Priya Sengal, Head of Development, and our CFO, Mike McDonald. Chris, Priya, and Mike will each make some opening comments And then we'll move to a Q&A session. And to allow us to get through as many questions as possible, we kindly ask that you limit yourself to one question.

I'll now turn the call over to Chris. Thank you very much, Chuck.
