EC vs PBR: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of September 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

Reading it: PBR is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. EC and PBR share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined EC and PBR exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

Ecopetrol S.A. is Colombia's largest company and one of the main integrated energy groups in the Americas, responsible for more than 60 percent of the country's hydrocarbon production and most of its transportation, logistics, and refining systems. Beyond upstream oil and gas, it holds leading positions in petrochemicals and gas distribution, runs exploration and production interests abroad (the U.S. Permian basin and Gulf of Mexico, Brazil, and Mexico), and, through its 51.4 percent stake in ISA, participates in power transmission, real-time grid management (XM), and toll-road concessions. The Colombian government owns roughly 88 percent of the shares, so EC functions as a national oil champion as much as a commercial enterprise.

Petroleo Brasileiro S.A. - Petrobras is the integrated energy company the Brazilian federal government controls through a majority of the voting common shares. Most of its value sits in exploration and production: deepwater fields in the Santos and Campos basins, where the pre-salt layer delivered a record ~2.78 million barrels of oil equivalent per day of the company's own output in the second quarter of 2026, out of a company total of ~3.34 million boed. Those barrels are unusually cheap to lift, under ~$6 per barrel before government take and depreciation, which is why Petrobras still earns well at oil prices that squeeze higher-cost producers. Downstream, it runs most of Brazil's refining system, which operated above 100% utilization in the quarter, alongside fuel logistics, natural gas processing and pipelines, fertilizers, and a small low-carbon portfolio. Crude exports approached ~1 million barrels per day.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• EC drivers: Oil price and refining leverage; High dividend and cash returns.
• PBR drivers: Pre-salt volumes at a cost few can match; Refining and gas as the domestic franchise.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: EC carries concentrated exposure to oil prices, so a crude downturn would hit revenue, earnings, and the dividend at the same time. For PBR, state control is the risk that overshadows the rest: the federal government holds a majority of the voting common shares, appoints the board and CEO, and prior administrations have set domestic fuel prices below import parity, which turned a producer's windfall into a subsidy for drivers.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick EC if you believe its drivers more; PBR if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the EC and PBR guides.

EC. Ecopetrol reported first-quarter 2026 revenue of about COP 28.6 trillion, EBITDA near COP 13.5 trillion, and net income around COP 2.9 trillion, beating expectations on strong refining margins. The stock consistently trades at a low earnings multiple and a high dividend yield, a valuation that reflects both its cash generation and the discount investors apply for emerging-market, commodity, and state-control risk. Figures are approximate and depend heavily on oil prices and the peso exchange rate.

PBR. Petrobras reports in Brazilian reais, and screeners routinely show the real figure with a dollar sign, which is how a ~R$548 billion revenue line becomes a fictitious ~$548 billion. Converted at recent rates that is about ~$106 billion, roughly a fifth of the number some sites display. Every figure above is labelled in the currency it was reported in, and the per-ADR numbers reflect the 2-to-1 ratio (each ADS equals two ordinary shares), which is also why per-ADR earnings look double the per-share amount.

Headline figures (approximate, July 2026): EC shows revenue (ttm) ~$30B, q1 2026 revenue ~COP 28.6T (~$7B), ebitda margin ~47%, market cap ~$26B; PBR shows revenue (ttm) ~R$548B (about ~$106B), net income (ttm) ~R$133B (about ~$26B), latest quarter (q2 2026) net income ~R$52.4B (about ~$10.4B), up ~97% year over year, adjusted ebitda (q2 2026) ~R$93.8B (about ~$18.6B); ~R$100.6B excluding one-off items.

EC and PBR are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.
