Illinois Tool Works delivered its most profitable quarter in company history in the second quarter of 2026, with operating income up 7.4% to $1.15 billion, revenue up 6.1% to $4.30 billion (4.5% organic), operating margin expanding 40 basis points to 26.7%, and GAAP EPS up 10.1% to $2.84. The standout was a sharp acceleration in demand, sequential revenue grew 7% against a 2% historical norm, with every segment beating its typical pace, led by welding (+14% organic), test & measurement and electronics (+10%, electronics +21%), and polymers & fluids (+7%), and with orders outpacing revenue in the CapEx-related segments. Customer-Back Innovation contributed 3% to first-half growth, ahead of plan and the key catalyst for sustaining 4%+ organic growth, while enterprise initiatives added 120 basis points to margin, free cash flow grew 41%, and the company returned over $1.2 billion to shareholders including a pulled-forward $750 million buyback. Management raised full-year guidance for the second time this year, lifting organic growth 1.5 points to a 3.5% midpoint and GAAP EPS by $0.15 to a $11.45 midpoint (9% growth), with all seven segments expected to grow organically and expand margins. The main headwind was a price-cost timing lag from crude-oil-derivative resin and chemical inflation, which diluted margin by 40 basis points (concentrated in specialty and automotive) and held full-year operating-margin guidance unchanged at 26.5%-27.5% and incrementals near 40%; management expects the lag to ease through the second half as input prices fall and price increases catch up. Softer spots included flat automotive OEM (Europe -5%) and food equipment (North America -4%), while construction posted its best organic growth in four years, and leadership reaffirmed its path to a 30%+ operating margin by 2030.
