At the close on September 10, 2026, Labcorp stock finished the New York Stock Exchange session at approximately USD 307, down about 4.3% from the prior close after a volatile trading day. Compared with the Russell 2000 index, which was cited as trading higher on the day in the same market wrap, the stock underperformed its small-cap benchmark during that session.
September 10, 2026 in numbers
Labcorp Holdings Inc. (ISIN US50540R4092, NYSE: LH) saw its shares open the September 10, 2026 session around USD 320 on the New York Stock Exchange before quickly losing ground. According to a same-day market wrap from Investing.com, the stock opened the session at USD 320.32, briefly touched a day high of USD 320.38, then sold off sharply to a session low of USD 305.45 before closing down about 4.3 percent on the day. The same report noted that Labcorp shares were sliding in afternoon trading to about USD 307.43, illustrating how the close settled near the lower end of the intraday range.
The September 10, 2026 trading came alongside a broader equity backdrop in which the Russell 2000 index was reported as positive, meaning Labcorp lagged a key small-cap benchmark on the day. A news brief from Scanx highlighted that the company discussed targets over the coming years while the Russell 2000 was referenced in the same context, underscoring the index comparison.
Investor Day guidance shapes today
The primary driver of the September 10, 2026 session was Labcorp's 2026 Investor Day, where management detailed a long-term growth and earnings framework and reaffirmed its existing full-year guidance. As MarketWatch reported on September 10, 2026, Labcorp reiterated adjusted earnings per share guidance for 2026 in a range of USD 18.10 to USD 18.55 and revenue expectations between USD 14.71 billion and USD 14.83 billion, while outlining further growth ahead. A detailed analysis from Benzinga noted that leadership is betting on artificial intelligence and specialty testing to drive growth through 2029, with management anticipating adjusted earnings per share between USD 18.10 and USD 18.55, slightly above a cited consensus of USD 18.01, and positioning the business for multi-year expansion.
The same Benzinga report stated that Labcorp shares were down about 3.73 percent to USD 309.12 during Thursday trading, which aligns with the roughly 4.3 percent decline highlighted by Investing.com and shows that the negative reaction to the Investor Day messaging persisted through the afternoon. A separate pre-market note from RTTNews earlier on September 10, 2026 mentioned that the shares were only marginally lower in pre-market trading before the Investor Day, illustrating that the bulk of the downside move came during the regular session as investors digested the long-term outlook and reaffirmed guidance.
Heading into today, September 11, 2026, the Investor Day commentary and the reiterated 2026 guidance remain the key reference points for Labcorp's stock as trading is set to resume on the New York Stock Exchange. The long-term revenue compound annual growth rate target mentioned in the Scanx coverage, framed at around 5 to 8 percent through 2029, and the 2026 adjusted earnings per share range communicated across MarketWatch and Benzinga reports give investors concrete figures to weigh against valuation and industry dynamics as the new session begins.
