Petrobras updates 2026 operational
and financial projections
—
Rio de Janeiro, November 10, 2026 –
Petróleo Brasileiro S.A. – Petrobras announces that it has raised its 2026 production projections. The estimate for total
oil and gas production attributable to Petrobras has increased from 3.1 million boed to a range of 3.3 million to 3.4 million boed. The
projection for oil and NGL production has increased from 2.5 million bpd to a range of 2.7 million to 2.8 million bpd.
The revision reflects the company’s
consistent progress in operational efficiency, with significant gains from investments made in recent years in maintenance and asset integrity,
as well as optimized reservoir management, increased nominal production capacity at certain projects, accelerated platform ramp-ups and
the bringing forward of first oil from P-79 in Búzios. Taken together, these factors strengthen the production growth trajectory
and increase the value captured from the company’s assets.

The 2026 projection for total Capex in
the Implementation Portfolio has been revised from US$ 19.4 billion to a range of US$ 24 billion to US$ 25.5 billion, while the projection
for cash investments in the Implementation Portfolio has increased from US$ 16.9 billion to a range of US$ 21 billion to US$ 22 billion.
The updated guidance does not represent an increase in the total costs of the projects.
The higher investment level is mainly
associated with foreign exchange effects and better-than-planned project execution. Notable factors include faster-than-expected progress
in the construction of Petrobras-owned FPSOs for the Búzios, Atapu and Sépia fields; greater rig availability, with most
rigs allocated to Búzios projects; and an increase in the number of well tie-ins. These factors have contributed to production
growth. In addition, Capex was affected by the projected localization of the Búzios 9 and 10 platforms in 2026, while the revised
cash investment projection takes into account the payment, scheduled for December, of the signing bonuses for the ANP (National Agency
of Petroleum, Natural Gas and Biofuels) auctions held in October.
The 2026 estimate for operating cash flow,
based on the Total Portfolio, has also been updated, increasing from US$ 35 billion to a range of US$ 45 billion to US$ 50 billion, reflecting
the new Brent price level and growth in oil and refined product production.
The 2026 projection for manageable operating
expenses (GOG) has increased from US$ 20.2 billion to a range of US$ 24.2 billion to US$ 25.5 billion. This revision is mainly due to
foreign exchange effects; higher oil and gas production, including expenses associated with bringing forward P-79; and higher logistics
costs, particularly because of the exceptionally high freight rates in 2026 and the increase in volumes transported. Despite this revision,
manageable operating expenses per barrel produced will remain competitive, with a projected 2% reduction compared with the actual figure
for 2025.
