Sintana Energy (LON:SEI) is entering an active period across its Atlantic Margin portfolio, according to the latest research note from Cavendish, which reiterates its Buy recommendation and 54.5p target price for the AIM-listed oil and gas explorer.
The Cavendish Company Comment, titled “Mid-year update”, was written by Research Analysts James Midgley and James McCormack and dated 2 July 2026. It highlights progress across Sintana’s portfolio, with Namibia remaining the main near-term focus, particularly PEL 83, where activity around the Mopane discovery is expected to provide important news flow over the coming months.
Sintana is described in the note as “A leading Atlantic Margin explorer, focussed on capital efficient, long-term value creation.” The company’s portfolio includes interests in Namibia and Uruguay, two areas that continue to attract industry attention from major operators.
Cavendish wrote: “With plenty of activity in the pipeline for the second half of the year, we reiterate our Buy recommendation and 54.5p target price.”
That comment neatly captures the tone of the research note. Cavendish points to a busy second half, with multiple potential catalysts, including drilling activity in Namibia and seismic progress in Uruguay.
At the time of the note, Sintana’s share price was 18.0p, with Cavendish’s 54.5p target price implying upside of 203%. The broker also left its valuation unchanged, maintaining its estimates alongside the Buy recommendation.
Key highlights from the Cavendish research note:
• Cavendish reiterates a Buy recommendation on Sintana Energy.
• The broker maintains its 54.5p target price, implying 203% upside from the 18.0p share price shown in the note.
• The key near-term focus remains Namibia, particularly PEL 83 and the Mopane appraisal programme.
• Drilling activity at Mopane is expected to commence over the coming months.
• The Mopane campaign is expected to include at least three wells over the next 18 to 24 months.
• Results from the Mopane wells are expected to support a formal Final Investment Decision, anticipated in 2028.
• First oil at Mopane is expected in 2032.
• Chevron is expected to drill the Nabba-1X well on PEL 90 in the fourth quarter.
• Sintana is funded for its interest in Nabba-1X, equivalent to a 4.9% stake.
• Cavendish values the Nabba well at 15.4p per share unrisked, net to Sintana.
• In Uruguay, Sintana holds a 40% stake in Area OFF-1 and 100% of Area OFF-3.
• Initial fast-track seismic data from Area OFF-1 is expected in the second half.
• The farm-out process at Area OFF-3 continues, with Cavendish noting recent moves by QatarEnergy and ENI into nearby acreage.
Namibia remains central to the investment case. Cavendish notes that activity at PEL 83 is expected to continue attracting attention, helped by the TotalEnergies farm-in, Galp’s resource upgrade at Mopane, and the planned three-well exploration and appraisal campaign. The appraisal drilling programme is designed to de-risk current reserve estimates, improve understanding of the reservoir for development planning, and test additional upside.
The note also highlights PEL 90 in the Orange Basin, where Chevron is preparing to drill the Nabba-1X well, expected in the fourth quarter. Although Chevron has not published details of the target, Cavendish’s valuation assumes the well is targeting 500 million barrels of gross recoverable resources, with a one-in-five geological chance of success. This gives the well potential significance for Sintana, despite the company’s relatively modest net exposure.
Uruguay is described by Cavendish as offering “blue sky upside”. Sintana has a 40% stake in Area OFF-1 and 100% of Area OFF-3, meaning it is more geared to exploration success in Uruguay than in Namibia. The research note says initial fast-track seismic data from the first phase of data collection at Area OFF-1 is expected during the second half, while the second stage is due to begin before the end of the year. The ongoing farm-out process at Area OFF-3 is also presented as a key potential catalyst.
Financially, Cavendish forecasts no revenue for the years shown in its estimates, which is typical for an exploration-stage oil and gas business before commercial production. The broker forecasts adjusted EBITDA of negative $3.8m for 2025E through 2028E, and adjusted EPS of negative 0.49p from 2026E through 2028E. The note shows net cash of £14.3m and a market capitalisation of £105.9m.
Final Thoughts:
Cavendish’s latest research note presents Sintana Energy as a company with several important operational events ahead. Namibia provides near-term drilling catalysts, particularly around Mopane and Chevron’s Nabba-1X well, while Uruguay offers additional exploration and farm-out potential. Sintana remains an exploration business, so outcomes will depend heavily on drilling results, partner activity and future commercial decisions. However, Cavendish’s unchanged Buy rating and 54.5p target price show that the broker continues to see meaningful potential across the company’s Atlantic Margin portfolio.
