Amphenol (NYSE: APH) Completes Stock Split Amid AI-Driven Growth and Valuation Concerns

• Stock Split Completed: Amphenol (NYSE: APH) completed a 2-for-1 forward stock split, with additional shares distributed after the September 2, 2026, market close and split-adjusted trading beginning September 3.
• AI-Driven Growth: Communications Solutions segment sales increased 85% year over year to approximately $5.38 billion, supported by strong demand for AI-related IT datacom products and contributions from acquisitions.
• Valuation Concerns: An August 2026 GuruFocus earnings-based DCF analysis estimated a pre-split intrinsic value of $99.59, compared with a then-current price of $157.01, producing GuruFocus’s reported margin-of-safety figure of -57.7%.

Amphenol (NYSE: APH) completed a 2-for-1 forward stock split after the market closed on September 2, 2026. Trading began on a split-adjusted basis on September 3.

Under the split, shareholders received one additional share for every share they owned. The number of outstanding shares doubled, while the price per share was adjusted to approximately half its previous level. The transaction did not immediately change Amphenol’s market capitalization or the total value of an investor’s position. Forward stock splits are generally intended to make shares more accessible and improve trading liquidity.

Amphenol is one of the world’s largest designers and manufacturers of electrical, electronic, and fiber-optic connectors, interconnect systems, antennas, sensors, and specialized cables. The company serves markets including automotive, aerospace, defense, industrial equipment, communications networks, and information technology.

Its competitors include TE Connectivity (NYSE: TEL) and Bel Fuse (NASDAQ: BELFB). Amphenol has expanded its AI and data-center connectivity capabilities through acquisitions, including CommScope’s Connectivity and Cable Solutions business and Wilder Technologies. Amphenol completed the $10.5 billion CommScope business acquisition in January 2026; it did not acquire the entire company.

Amphenol’s second-quarter 2026 results demonstrated substantial growth. Total company sales increased 55% year over year to approximately $8.76 billion. Communications Solutions segment sales rose 85% in U.S. dollars and 42% organically to approximately $5.38 billion, accounting for around 62% of total sales.

The segment benefited from exceptional organic growth in the IT datacom market, particularly for AI-related applications, as well as contributions from acquired businesses. Amphenol’s IT datacom sales increased 89% year over year and 63% organically, with management attributing much of the growth to demand for high-speed copper and fiber-optic products used in AI infrastructure. 

Before the split, Amphenol shares closed at $160.08 on September 2, down 1.9% for the session. That closing price corresponds to a split-adjusted reference price of approximately $80.04. The stock’s pre-split 52-week high was $178.52, reached on June 30, equivalent to $89.26 on a split-adjusted basis.

Despite the company’s strong operating performance, its valuation remains an important consideration. On August 24, 2026, GuruFocus published an earnings-based DCF analysis estimating Amphenol’s pre-split intrinsic value at $99.59, compared with a then-current share price of $157.01. Under GuruFocus’s methodology, this produced a reported margin of safety of -57.7%.

After adjusting for the stock split, those values would be approximately $49.80 in estimated intrinsic value and $78.51 in market price, leaving the valuation conclusion unchanged. GuruFocus also estimated a lower pre-split value of $84.59 using its free-cash-flow model. However, the service assigned Amphenol a low predictability rating of one out of five stars, meaning the DCF estimates should be interpreted cautiously. 

Overall, Amphenol continues to benefit from strong AI-infrastructure demand, organic growth, and strategic acquisitions. Nevertheless, its elevated market valuation means investors are pricing in substantial future growth, making continued execution an important factor in the stock’s performance.
