Alphabet Inc. (GOOG) shares came under heavy after-hours selling pressure following third-quarter results that combined strong revenue growth with weaker reported earnings. The company posted revenue of $127.6 billion, up 25% year over year, while Google Cloud revenue surged 103% to $30.7 billion on enterprise demand and Google Search revenue grew 12%. However, an $8.7 billion investment loss weighed on profitability, and diluted earnings per share fell to $2.12, missing Wall Street estimates and sending the stock lower once the market closed.

Shares Slide as Investment Losses Hit Earnings

Alphabet shares gained 1.60% to close the regular session at $321.89 before falling 8.90% to $293.25 in after-hours trading. After-hours sessions trade outside regular market hours on typically lighter volume, so the size of a move in that window does not automatically set the price when regular trading resumes. The decline followed quarterly results that showed robust business growth but weaker reported profitability. The company's market capitalization stood at approximately $3.9 trillion, a level that places it among the most valuable publicly traded companies in the world.

For the quarter ended September 30, 2026, Alphabet generated $127.577 billion in revenue, up from $102.346 billion in the third quarter of 2025. Diluted earnings per share nonetheless dropped to $2.12 from $2.87 in the year-ago period. The company attributed much of the earnings pressure to unfavorable changes in investment-related income, a category that swung from large gains to substantial losses during the period. Because gains and losses on equity securities flow through net income under standard accounting rules, reported earnings can diverge sharply from operating performance — a gap that defined this quarter's results.

Alphabet recorded an $8.7 billion loss on equity securities, a sharp reversal from the $10.7 billion gain it posted in the third quarter of 2025 — a $19.4 billion swing in investment results between the two periods. The swing dented reported earnings even as operating performance strengthened across the company's core businesses. Operating income rose to $40.576 billion from $31.228 billion, and operating margin improved to approximately 31.8%.

Google Cloud Revenue More Than Doubles on Enterprise Demand

Google Cloud delivered Alphabet's strongest segment growth of the quarter, with revenue climbing 103% year over year to $30.709 billion. The unit benefited from rising demand for computing infrastructure, enterprise services, and systems supporting advanced AI workloads — demand that has made cloud infrastructure one of the most closely contested areas of enterprise technology. As a result, Google Cloud contributed significantly to Alphabet's overall revenue expansion, accounting for nearly a quarter of the company's total quarterly revenue.

Cloud operating income also increased substantially, reaching $11.121 billion compared with $3.594 billion a year earlier — equivalent to an operating margin of roughly 36% for the unit. The improvement reflected stronger revenue alongside greater profitability within the unit, underscoring Google Cloud's growing contribution to Alphabet's earnings and its expanding role in enterprise technology spending.

Alphabet's broader Google Services division generated $96.302 billion in revenue, an 11% annual increase. Google Search and other revenue rose to $63.350 billion from $56.567 billion, while YouTube advertising revenue reached $11.207 billion. Together, the figures pointed to continued demand across Alphabet's established advertising businesses alongside its fast-growing cloud unit.

Search and Advertising Anchor the Revenue Base

Google advertising revenue increased to $82.012 billion from $74.182 billion in the prior-year quarter, keeping advertising at roughly 64% of Alphabet's total revenue. Search remained the largest contributor, with revenue up 12%, supported by stronger query activity and continued advertiser demand. YouTube advertising revenue advanced from $10.261 billion to $11.207 billion.

Google subscriptions, platforms, and devices generated $14.290 billion, up from $12.870 billion a year earlier, bringing total Google Services revenue to $96.302 billion and reinforcing the division's importance to Alphabet's financial performance. Google Network revenue, by contrast, rose only slightly, to $7.455 billion from $7.354 billion, highlighting slower growth in that unit relative to the rest of the business.

Alphabet also reported $26.170 billion in net income available to common stockholders, down from $34.979 billion in the previous year's quarter. The year-over-year decline stood in sharp contrast to the company's operating income growth, as investment-related losses flowed through to the bottom line.

Overall, Alphabet delivered strong top-line growth and record cloud performance in the quarter, but weaker reported earnings — driven by the $8.7 billion loss on equity securities — triggered the sharp after-hours decline in the company's stock.
