New York, Jan 22, 2026, 13:34 (EST) — Regular session
- Thermo Fisher shares up $2.03, or 0.3%, at $638.33 in afternoon trading
- Stock closed Wednesday at $636.30, a 52-week closing high
- Investors are focused on the company’s Jan. 29 results and 2026 outlook
Thermo Fisher Scientific Inc (TMO) shares rose $2.03, or 0.3%, to $638.33 on Thursday afternoon, after briefly climbing as high as $643.66 earlier in the session.
The stock is hovering near its best levels in a year as investors line up ahead of the company’s fourth-quarter and full-year 2025 results, due before the market opens on Jan. 29. Thermo Fisher said it will host a conference call that morning at 8:30 a.m. ET. 1
That timing matters for the life-sciences tools group, which tends to trade off order trends and forward guidance more than anything else. Thermo Fisher’s print often sets the tone for peers with similar exposure to pharma and lab spending.
Thursday’s lift came with U.S. stocks broadly higher. The S&P 500-tracking SPDR S&P 500 ETF Trust (SPY) was up about 0.8%, while the Health Care Select Sector SPDR Fund (XLV) added about 0.3%.
On Wednesday, Thermo Fisher rose 2.79% to close at $636.30, a new 52-week high — the highest price in the past year — surpassing a prior peak of $629.87 set on Jan. 15, according to market data. Volume was 3.2 million shares, above the 50-day average of 1.8 million. 2
A separate SEC filing dated Jan. 21 showed Thermo Fisher’s 3.200% senior notes due 2026 were removed from listing and registration on the New York Stock Exchange. Form 25 is a delisting notice for a specific security — in this case a class of bonds — and is separate from the company’s common stock. 3
Earlier this month, Thermo Fisher said it would collaborate with Nvidia to build artificial intelligence-based lab automation and software tools. “Artificial intelligence coupled with laboratory automation will transform how scientific work is performed,” Thermo Fisher executive vice president Gianluca Pettiti said. “We are entering the era of ‘lab-in-the-loop’ science,” said Kimberly Powell, Nvidia’s vice president of healthcare. 4
Peers were mixed on Thursday. Waters was up about 0.4%, while Danaher and Agilent slipped about 0.3% each.
But the run into earnings cuts both ways. With the stock near a one-year high, a cautious outlook or any hint that customers are pushing out spending could trigger quick profit-taking.
The next catalyst is Jan. 29, when Thermo Fisher reports and investors dig into 2026 guidance, order commentary and whether the recent momentum in the shares has more fuel.
