Bannerman Energy Eyes Q4 FID as Etango Uranium Build Stays on Budget
Key Takeaways
- Bulk earthworks at Etango are approximately 99% complete and 14,700m³ of concrete has been poured across Phase 1 and 2A, representing 86% of planned volume — all activities are on budget and on schedule as at 29 September 2026.
- Bannerman Energy is targeting a Final Investment Decision jointly with CNOL during Q4 2026, immediately following completion of the CNOL strategic investment and joint venture transaction the prior week.
- Full-scale construction is expected to commence promptly after FID, with mechanical packages already ready for order placement and the critical path timeline preserved by the early works programme.
- Definitive agreements with NamWater (executed June 2026) and NamPower are in place, removing two key sovereign utility risks ahead of FID, with early procurement for the 132 kV powerline planned for Q4 2026.

CEO perspective
Gavin Chamberlain, Managing Director and Chief Executive Officer
“Construction work on site has continued in line with expectation, with our four Namibian contractors performing consistently well and aligned to both schedule and cost. The final phase of the large-scale bulk earthworks package is expected to be complete before year end, representing a key milestone in our early works activities and the overall development of Etango.
“The early works programme, and particularly the bulk earthworks contract, has been a seminal workstream in maintaining the critical path timeline for Etango. With the completion of the CNOL strategic investment and joint venture transaction last week, we are making final preparations towards a targeted Final Investment Decision (FID) on Etango during Q4 2026. I am delighted to say that FID is set to be followed promptly by the commencement of full-scale construction at Etango – which we are rapidly gearing up for across site, within the owner’s team and across our key contractor partners.”
What is a Final Investment Decision — and why does Q4 2026 matter?
A Final Investment Decision (FID) is the formal commitment by a company and its partners to deploy full capital and proceed to complete construction. It is effectively the point of no return: once taken, it unlocks full-scale activity, contractor mobilisation, and major procurement across the project.
For investors, FID is a material re-rating event. It converts a development-stage asset into a construction-stage asset, which typically changes the risk profile significantly and draws a different class of capital. Institutional investors who cannot hold pre-FID projects often enter at this point, and the project de-risking that FID represents is usually reflected in how the market prices the stock.
At Etango, FID will be taken jointly with CNOL as joint venture partner, following completion of the CNOL strategic investment and joint venture transaction the week prior to this announcement. Critically, the early works programme has been deliberately structured to preserve the critical path timeline. This means FID is not a standing-start event. Construction is already underway, concrete is being poured, earthworks are nearly done, and mechanical packages are ready for order. The transition to full-scale construction is expected to follow promptly.
Local participation and safety culture — building Etango the right way
Etango’s construction model incorporates deliberate Namibian SME participation. Selected non-critical works are being delivered by local Namibian-owned businesses: the gatehouse by Dappa Trading Group CC through K Neumayer Civil Contractors, fencing works by Dannie Construction CC, and in-situ culvert works by Nelugo Trading Enterprises CC through Namibbeton. These opportunities form part of Bannerman’s broader approach to increasing local participation in the project’s development.
On permanent infrastructure, two definitive agreements are now in place that reduce sovereign and utility risk for the project. A permanent water supply agreement with NamWater was executed in June 2026, with Phase 1 pipeline construction now ~90% complete. A definitive power supply agreement with NamPower is also in place, with EPCM consultants Addiza Energy Solutions and Transmission Consulting Services (TCS) appointed for the 132 kV overhead powerline and substation design. Early procurement for this infrastructure is planned for Q4 2026.
On safety, the project achieved 1.6 million Lost Time Injury (LTI)-free hours before recording its first LTI in more than 16 years working on the Etango project. On 2 September 2026, a contractor employee operating a compactor sustained a hairline fracture to his left foot and received medical attention. The company has responded by reinforcing a culture where safety is personal, accountability is visible, and leadership is demonstrated through action.

What comes next for Bannerman and Etango
The near-term roadmap is well-defined:
- Bulk earthworks Phase 4 completion — targeted December 2026
- FID — targeted Q4 2026, taken jointly with CNOL
- Full-scale construction commencement — expected promptly post-FID
- Early procurement for 132 kV power infrastructure — planned Q4 2026
- Mechanical packages — ready for order placement upon FID
The construction case for Etango carries several layers of de-risking that are worth understanding. Early works have kept the critical path intact, meaning FID does not reset the clock. The joint venture with CNOL provides both strategic validation and shared capital commitment from a major state-aligned nuclear entity. And Namibia’s credentials as a uranium jurisdiction are well-established: the country has a 45-year history of uranium production and export and is the world’s third-largest uranium producer, offering political stability and an assertive development agenda.
Etango is transitioning from a development asset to a full construction-stage uranium project. With FID anticipated during Q4 2026 and full-scale construction expected to follow promptly, the project’s next phase is approaching rapidly.
