Coca-Cola (KO) Q2 2026: H1 Operating Cash Flow Swings to $7.5B, but the $14 Billion Tax Question Sits Off the Balance Sheet

Coca-Cola's second-quarter margins and first-half cash flow both improved, but the two improvements are not the same kind of event. Operating margin expanded to 34.92% from 34.14%, and operating cash flow for the first half swung to $7,543 million from negative $1,391 million a year earlier — an $8,934 million reversal, of which $6,173 million (69%) is simply the absence of the fairlife contingent-consideration payment made in March 2025. Adding that payment back to the prior-year base gives a like-for-like comparison of $7,543 million against $4,782 million, still a 57.7% increase — so there is genuine underlying improvement, just less than a third of what the headline swing implies. Meanwhile, the U.S. Court of Appeals for the Eleventh Circuit heard the company's transfer-pricing appeal on June 25, 2026, leaving $6.0 billion already paid to the IRS plus $514 million of accrued interest receivable awaiting a ruling the company has reserved only $529 million against — and, separately, a disclosed potential incremental liability of roughly $14 billion for the 2010–2025 tax years that appears nowhere on the balance sheet. For a defensive staple that trades on the predictability of its cash returns, the single largest swing factor is now a court decision, and most of that exposure is off-balance-sheet.

Note on period and sources: all financial figures are drawn from Coca-Cola's Form 10-Q for the three and six months ended July 3, 2026, filed July 29, 2026 — the company's second quarter of fiscal 2026 — unless otherwise noted. Quarterly periods other than Q4 end on the Friday closest to the calendar quarter-end. Volume, organic revenue, comparable EPS and guidance figures are from the company's Q2 2026 earnings release dated July 28, 2026.

What the earnings release led with. The 10-Q is the source for everything below, but the numbers that moved the stock came from the July 28 release: unit case volume up 5%, organic (non-GAAP) revenue up 6%, and comparable EPS of $0.97, up 11%. Management raised full-year guidance to roughly 5% organic revenue growth and 9–10% all-in comparable EPS growth. Note the gap between comparable EPS of $0.97 and reported diluted EPS of $1.03 for the quarter — the difference is the non-operating gains discussed in section 2-1, which is precisely why the reported figures below need normalizing before they are compared with anything.
