APH sets 2-for-1 stock split effective September 3

Amphenol Corporation has announced a 2-for-1 stock split, effective September 3, 2026. Every existing share becomes two shares at half the price. Total position value is unchanged.

For holders, the split is cosmetic — more shares at a lower per-share price, but the same economic interest. For short sellers, borrowed share positions double in share count at half the price per share, leaving the dollar exposure identical. With short interest at just 1.4% of free float, a cost to borrow of under 0.5%, and 1.9 days to cover, the borrow market is loose and the split creates no meaningful friction for shorts around the effective date.
