Amphenol stock price steadies near $145 after earnings whipsaw as traders eye Tuesday’s U.S. shutdown vote

NEW YORK, Feb 2, 2026, 21:17 (EST) — Market closed.

Amphenol Corp shares ended Monday’s session 0.6% higher at $144.93 and were trading roughly 0.4% up in after-hours, hovering close to the post-earnings lows set last week. MarketWatch

That’s key as Tuesday approaches, with the stock acting volatile once more after a steep reset in late January. Investors now face the question: is this pullback just a breather, or the beginning of a deeper slide?

Monday saw a broad trading range, from $144.00 up to $148.51, on volume near 9.9 million shares. The stock remains roughly 13% below its close on Jan. 27, following a steep 12.2% plunge on Jan. 28. StockAnalysis

The rally showed strength Monday as the S&P 500 climbed 0.54%, while the Dow surged 1.05%, led by widespread gains in industrial stocks. MarketWatch

The Wallingford, Connecticut-based firm reported on Jan. 28 that fourth-quarter sales jumped 49% to $6.4 billion. Adjusted earnings per share, which exclude certain items, rose to $0.97. For the first quarter, it projected sales between $6.90 billion and $7.00 billion, with adjusted EPS expected in the range of $0.91 to $0.93. This outlook factors in roughly $900 million in sales from its CommScope CCS business. CEO R. Adam Norwitt described the quarter as “record” and said the results “significantly exceed[ed] the high end of our guidance.”

Traders have been debating the mix since then. How much of the 2026 growth stems from core demand, and how much reflects added revenue from acquisitions?

Still, some uncertainties remain. In that same release, Amphenol revealed a $100 million accrual linked to tax notices concerning certain China subsidiaries. The company cautioned the potential expense could climb to roughly $300 million, though the timing remains uncertain. Amphenol Investors

Macro could get choppier this week. The U.S. Bureau of Labor Statistics announced the January employment report won’t drop as planned due to the partial federal shutdown. Emily Liddel said in a statement that “the release will be rescheduled upon the resumption of government funding.” The House of Representatives was set to hold a final vote Tuesday. Former BLS commissioner Erica Groshen cautioned that the agency’s “staff is already under extreme pressure” if the shutdown lingers. reuters.com

National Healthcare Properties Files for IPO on Nasdaq with $100M-$200M Target
April 7, 2026, 2:50 PM EDT. New York-based National Healthcare Properties, a senior housing real estate investment trust (REIT), has filed for an initial public offering (IPO) with the U.S. Securities and Exchange Commission. The IPO aims to raise between $100 million and $200 million, with shares expected to trade on the Nasdaq under the ticker symbol NHP. Proceeds will be used to repay debt or acquire properties. The REIT reported a reduced net loss of $57.7 million in 2023, across a portfolio of 167 properties valued at $2 billion, including senior housing units and outpatient medical buildings. This move follows the recovery of the senior housing sector after pandemic challenges and comes shortly after Healthpeak Properties' spinoff Janus Living raised $878 million in its IPO.
