Across the 2021-2025 window, KO's operating margin has compressed from 27% to 21% and back to 28.7%. The 2025 print is the highest in the data series. That margin level has historically been associated with the mid-cycle peaks that the company has briefly touched, not held.
The Signals Desk position is that the 2025 margin is closer to a new normal than to a cyclical peak. Three structural drivers support that view: the post-refranchising bottler economics now contribute a higher share of operating income at lower fixed-cost intensity; the mix shift toward zero-sugar and premium water carries a 200-300 basis point gross margin advantage versus traditional carbonated; and the Costa Coffee build-out (acquired in 2018) has finally crossed the operating income breakeven at scale.
If the 28% operating margin holds through 2026 and 2027, even with modest volume growth of 3-4%, the implied FY2027 operating income is $15-16 billion, against current consensus of approximately $14 billion. That is the 5-7% gap that we believe the market is mispricing. At a 23x forward multiple, the gap is worth roughly $9 of fair value, taking the stock from $76 to $85.
Historically, beverage majors that have produced two consecutive years of operating margin above their 5-year average have re-rated within 12-18 months. KO's first year is in the books. The second is the catalyst.
One further angle on the margin story. Costa Coffee, acquired in 2018, was a drag on operating margin for the first five years post-close. The UK hospitality sector faced pandemic disruption, reopening costs, and energy-cost inflation that pushed the brand's contribution below breakeven. The 2025 print showed Costa contributing positively for the full year, with approximately 200 basis points of operating margin at scale. That transition from drag to accretion alone is worth 40-60 basis points of consolidated margin improvement.
Consider also the longer history. Between 2005 and 2015, KO's operating margin oscillated in a 21-24% range. Between 2015 and 2020, the range shifted to 23-28% following the early-stage portfolio refranchising. The 2025 print at 28.7% represents the highest observation in the entire 20-year data series. If the next-cycle range shifts up by 200-300 basis points versus the 2015-2020 baseline, the implied steady-state EBIT runs at $15-17 billion by 2028, materially above consensus.
