Novo Nordisk sinks after Ozempic’s key ingredient fails to slow down Alzheimer’s in trials

Novo Nordisk is down nearly 8% in trading in Europe, with its US-listed ADRs dropping a similar amount, after the pharma giant shared that oral semaglutide — a key ingredient behind its Ozempic and Wegovy drugs — didn’t slow Alzheimer’s disease in two trials.

Per the company’s press release, oral semaglutide failed to show a statistically significant reduction in early-stage Alzheimer’s disease progression compared to a placebo across two large-scale, late-stage trials. From the release:

“The two trials were randomised, double-blinded, enrolled a total of 3808 adults and evaluated the efficacy and safety of oral semaglutide compared to placebo on top of standard of care.”

Treatment with semaglutide did result in improvement of some Alzheimer’s disease-related biomarkers, but it “did not translate into a delay of disease progression.”

Noting that the trials were conducted “despite a low likelihood of success” from the start, Chief Scientific Officer Martin Holst Lange commented that “while semaglutide did not demonstrate efficacy in slowing the progression of Alzheimer’s disease, the extensive body of evidence supporting semaglutide continues to provide benefits for individuals with type 2 diabetes, obesity, and related comorbidities.”

Injectable semaglutide, sold under the brand names Ozempic and Wegovy, is approved in the US and EU to treat diabetes, obesity, and heart conditions. Expanding the list of conditions its blockbuster drug can treat could be a lifeline for the company as it loses ground in the weight-loss and diabetes market to Eli Lilly.

Lilly, notably, also makes Kisunla, an injection that treats early-stage Alzheimer's disease. The drug, which was approved last year, is expected to make $224.4 million in revenue this year.

AI “bottleneck” stocks are the big winners halfway through a tumultuous week

Memory stocks and chip machinery companies are bouncing Wednesday, following a strong Oracle earnings report that bolstered confidence in the durability of the AI data center build-out.

In fact, Sandisk is the top performer of the S&P 500 so far this week, rising more than 21% from Friday’s close, as of shortly after 2 p.m. ET. Memory chip maker Micron is second in line, up more than 13% in weekly gains, and hard disk drive maker Western Digital is also getting a lift.

Other big winners so far this week are some of the so-called semicap shares — makers of the ultraprecise machines that turn silicon into actual semiconductors — with Lam Research and KLA Corp both racking up gains of about 10% on the week. Applied Materials is up about 8% this week.

Thematically speaking, both memory stocks like Sandisk and Micron as well as semicap shares like KLA have been part of the “buy the bottleneck” trade, in which investors buy companies they believe sit at key pinch points in the AI supply chain and therefore have pretty tremendous pricing power. Through that lens, the stocks’ bounce might reflect some additional excitement about the durability of the data center boom after Oracle’s results, which included a larger-than-expected capex number as well as sales guidances that was higher than Wall Street was forecasting.

But the bounce also may be the less interesting market phenomenon of mean reversion rearing its head, as these stocks were also some of the most beaten down in the S&P 500 last week, when Sandisk lost 17% and Lam lost about 15%, for example. So, some snapback may merely be a market reflex.

Papa John’s spikes following report of a $47-per-share take-private offer from Qatari investment fund Irth Capital

A few weeks after announcing it would close 300 stores by the end of next year, Papa John’s is drawing fresh take-private interest from Irth Capital, an investment fund backed by a member of the Qatari royal family.

Papa John’s shares were up 19% on Wednesday afternoon, on pace for their best day since February 2025.

According to The Wall Street Journal, Irth is offering $47 per share for PZZA, valuing the company at about $1.5 billion. The fund currently holds a roughly 10% stake in Papa John’s, per the report.

Irth has tried to take Papa John’s private before, offering $60 per share in a joint bid with Apollo Global in June of last year. In October, Apollo Global again offered to take the company private at $64 per share. That offer was later withdrawn.

Broadly, the pizza category is being increasingly dominated by Domino’s, which opened 700 stores globally last year and has a market cap 9x greater than Irth’s latest reported offer for Papa John’s.
