Business Insider reported an AWS infrastructure executive expects Amazon to stay free-cash-flow negative for the next couple of years

Per Business Insider, Kalyanaraman of AWS Infrastructure expects Amazon to remain free-cash-flow negative for "the next couple of years or so," and some AWS sites had room for racks but not enough power to turn them on. One August email projected about $5 billion of Nvidia GB300 rack deliveries that month, then roughly $3 billion a month.

Citgo reportedly raised its 2026 EBITDA outlook to $7.7-8.0 billion from $5.8 billion on surging fuel margins

Per an investor document reported by Bloomberg, Citgo lifted its full-year 2026 EBITDA outlook to $7.7-8.0 billion from the $5.8 billion it set in August, on surging fuel margins. TheValueist calculated that nine-month EBITDA of $4.5-4.8 billion implies a fourth quarter of $2.9-3.5 billion, 1.8 to 2.3 times the average of the first nine months, and called it extremely bullish for PADD 3 refiners given Citgo's footprint.
