Moves are after-hours prices as of 5:20 p.m. ET (5:18 p.m. for Stryker), against Thursday’s 4 p.m. close. Twilio (TWLO) also plunged 18.5% after hours, more than any of these except Intel, even though its third-quarter results and its fourth-quarter revenue forecast topped estimates, according to Investing.com; we found no clear explanation for the drop by press time.

**Intel (INTC)**, -19.6%: The chipmaker forecast fourth-quarter revenue of $15.0–16.0 billion, well short of the $17.07 billion analysts expected, according to LSEG data cited by Reuters. A memory-chip shortage is hurting PC sales, Reuters reported, and a deadly explosion at Intel’s factory in Israel will cut about $300 million from the quarter’s revenue, Reuters and Yahoo Finance said.

**Reddit (RDDT)**, -16.7%: Third-quarter revenue rose 53% to $895 million, ahead of estimates, but Reddit forecast $1.00–1.03 billion for the fourth quarter, below the $1.05 billion analysts expected, according to Investing.com. In its shareholder letter, Reddit also said traffic sent from search engines was down “meaningfully” and that daily users could fall by a low-double-digit percentage in the fourth quarter if that decline continues, a warning Investing.com also reported.

**Stryker (SYK)**, -12.1%: The medical-device maker’s sales of $6.52 billion and adjusted earnings of $3.52 a share both came in below the $6.62 billion and $3.55 analysts expected, Investing.com reported, and it cut its 2026 forecast for organic sales growth to 6.5%–7.0% from the 8.3%–9.3% it gave in July. The quarter “did fall short of our expectations,” Chair and Chief Executive Kevin Lobo said in the results release.

**Pinterest (PINS)**, -11.9%: Revenue rose 12% to $1.17 billion, short of the $1.21 billion analysts expected, and adjusted earnings of 46 cents a share missed the 49-cent estimate, according to Investing.com. Pinterest added users, reaching a record 661 million a month, but revenue per user rose only 1%, the results release showed, and it guided to fourth-quarter revenue growth of 8%–12%.

**Amazon (AMZN)**, -6.5%: Earnings of $1.89 a share missed estimates and the $28.5–33.5 billion fourth-quarter operating income forecast fell short, Yahoo Finance and investingLive reported, and ad sales missed too, Reuters said. That outweighed 39% growth at AWS, its cloud arm. Full story
