Coca-Cola FEMSA (KOF) Q4 2025 earnings review
Volume Rebounds, But Earnings Quality is Poor
Coca-Cola FEMSA broke its mid-year slump with consolidated volume growing 1.3% in Q4, driven by a record December in South America and sequential recovery in Mexico. However, the reported 13.3% surge in operating profit is an illusion—it was heavily inflated by Ps. 1.15 billion in insurance recoveries. Excluding these one-offs, operating income actually fell 2.1% as labor and depreciation squeezed margins. Looking into 2026, management expects a tough road in Mexico due to a large IEPS excise tax hike, guiding for renewed volume declines, which places the burden of growth entirely on Brazil and efficiency initiatives.
🐂 Bull Case
After a brutal Q2 where Mexico volumes collapsed ~10%, aggressive affordability plans and returnable pack rollouts have nearly halted the bleed, bringing Q4 declines to just -0.9%.
South America division volume grew 3.0%, with Brazil hitting its highest Q4 on record. Favorable weather, election-related spending, and social programs are providing strong tailwinds.
🐻 Bear Case
The headline 13.3% operating profit growth hides a grim reality. Without Ps. 1.15 billion in insurance recoveries, operating profit declined 2.1% and margins contracted 90 bps.
A severe IEPS excise tax increase in Mexico will force major price hikes onto an already sluggish consumer base. Management explicitly expects this to drive low-to-mid single-digit volume declines in their largest market next year.
⚖️ Verdict: ⚪
Neutral. The top-line momentum and digital execution are impressive, but structural margin compression and a looming tax-driven volume hit in Mexico make the near-term setup highly challenging.
Key Themes
Normalized Margins Are Contracting
While reported operating margin expanded 160 bps to 17.6%, this was strictly due to insurance claim payouts. Normalized operating margin actually contracted 90 bps to 16.1%. This deterioration was driven by higher fixed costs, specifically labor and depreciation, which outpaced favorable PET and sweetener raw material pricing.
Macro: IEPS Tax Hike Derailing Mexico Recovery
Just as Mexico was recovering from a mid-year demand shock, a new IEPS excise tax is forcing painful price increases. Management notes consumer elasticity is behaving 'as expected'—meaning sluggish demand—and plans to lean heavily on returnables and affordability packs to defend household penetration. They view this as a 12-month headwind.
Juntos+ Advisor AI Driving Market Execution
Digitalization is translating directly into higher sales and share gains. The rollout of the Juntos+ Advisor tool is optimizing sales force routes and compliance. In Brazil, visitation efficiency increased by 9.2 percentage points to 95.6%, while Mexico improved by 5.5 percentage points to 96.5%.
Zero-Sugar Franchise Acceleration
The company's 'Brazil playbook' for zero-sugar beverages is working exceptionally well. Coke Zero grew 14% in Mexico and an aggressive 44% in Brazil during FY25. Even more striking is Sprite Zero, which grew 93% in Brazil and now accounts for over 20% of the total Sprite brand volume.
Gross Margin Pressures Anticipated in 2026
Consolidated gross margin contracted 60 bps to 46.7% in Q4 due to unfavorable product mix and fixed costs. Looking to 2026, management warned of upcoming pressure from rising aluminum prices, which will require strict control of fixed expenses to keep EBIT margins flat.
Other KPIs
Decelerating. Financing expenses surged 38.4% YoY. This was driven by lower interest income due to depleted cash positions and lower rates in Mexico, combined with higher interest expenses from the U.S. dollar-denominated 2035 bond issued earlier in the year.
Reversing. The significant outflow in working capital this quarter was explained as a normalization effect. In Q4 2024, the rollout of SAP/4HANA caused a massive temporary spike in accounts payable. Management confirms this disruption is now fully cleared.
Guidance
Stable. Following a 1.8% decline in FY25, management expects a mild recovery. This is a blended expectation: strong tailwinds in South America will have to perfectly offset the expected tax-driven volume destruction in Mexico.
Reversing. Mexico had almost stabilized by Q4 2025 (-0.9%), but the IEPS excise tax pass-through will force volumes back into contraction for the duration of 2026.
Stable. Building on a strong Q4, management expects continued growth fueled by election-related spending, social programs, and FIFA World Cup activations.
Decelerating. CapEx is stepping down from 8.2% of revenues in 2025. Major capacity additions (like the Southeast plant in Mexico and the Porto Alegre recovery in Brazil) are largely completed, allowing for better free cash flow conversion in 2026.
Key Questions
Margin Bridge for 2026
You noted that aluminum costs will pressure gross margins in 2026. Given the volume declines expected in Mexico and limited pricing power due to the IEPS tax, exactly what fixed-cost levers remain to achieve your goal of flat EBIT margins?
Affordability vs. Profitability in Mexico
As you push returnable and multi-serve affordability packs to defend household penetration against the IEPS tax, at what point does this mix shift start severely degrading unit economics?
Capital Allocation Timing
With net debt/EBITDA well below 1.0x and CapEx requirements stepping down to 7.0-7.5% of revenues, what specific milestones or macro signals in H1 2026 do you need to see before announcing enhanced shareholder returns?
