Plexus Holdings (LSE:POS) has secured a two-year engineering agreement with Cactus Wellhead LLC to design, develop and qualify a new generation of wellhead products for offshore energy projects. The work will draw on Plexus’s engineering expertise and testing facilities in Aberdeen, further strengthening its position as a specialist provider of advanced wellhead technology.

As part of the agreement, Plexus will receive an initial £1 million commitment payment, secured by a debenture over the company’s assets. The contract is also expected to generate up to an additional £1.5 million in revenue over its duration, with the potential for further income if the scope of work expands. All engineering and development activities will be undertaken by Plexus’s in-house team, providing greater revenue visibility while supporting skilled employment and technical capabilities at its Aberdeen operations.

The partnership reinforces Plexus’s role within the offshore energy supply chain and highlights continued demand for its specialist engineering services. The contract provides a committed revenue stream, creates opportunities for additional project work and strengthens the company’s relationship with a leading international wellhead provider.

Despite the positive contract win, Plexus continues to face financial challenges following weaker trading performance and negative cash flow in 2025. The company’s technical indicators also remain subdued, with the share price trading below key moving averages and momentum remaining weak. Valuation support is limited by ongoing losses and the absence of a dividend.

Caledonia Mining (LSE:CMCL) produced 17,360 ounces of gold from its Blanket Mine in Zimbabwe during the second quarter of 2026, representing an 18% increase compared with the first quarter. The improvement was driven by better access to higher-grade mining areas and an increase in average plant grades. Although production was below the record level achieved in the second quarter of 2025, the company reaffirmed its full-year production guidance of between 72,000 and 76,500 ounces, with output expected to be weighted towards the second half of the year.

Management said initiatives to improve access to higher-grade ore are delivering encouraging results, with mined grades now averaging around 3g/t. Production is forecast to strengthen further during the remainder of 2026, supported by improved mine development, the completion of an upgrade to the elution plant that will enable processing of stockpiled fine-grain loaded carbon, and the introduction of a seven-day operating schedule. The extended working week is expected to increase ore throughput by approximately 200 tonnes per day.

Residential Secure Income plc (LSE:RESI) has taken another major step in its managed wind-down following the completion of the Retirement Disposal of its retirement housing portfolio. Through its subsidiary, ReSI Portfolio Holdings Limited, the company received consideration comprising £62.3 million in newly issued Living REIT plc shares and £45 million in cash. The 66,103,233 new Living REIT ordinary shares were admitted to trading on the London Stock Exchange’s Main Market on 16 July 2026.

The Living REIT shares will be distributed directly to eligible RESI shareholders through an in specie distribution. Shareholders on the register as of 22 July 2026 will receive approximately 0.3570 Living REIT shares for every RESI share held, with fractional entitlements rounded down. The cash proceeds are expected to be returned during the third quarter of 2026 through a bonus issue and redemption of B shares, subject to the company retaining sufficient funds to meet transaction costs, working capital requirements, tax obligations and expenses associated with its planned exit from the UK REIT regime.

The combination of share and cash distributions represents a key milestone in the company’s orderly wind-down strategy. Shareholders will receive immediate value through the planned capital return while retaining exposure to the retirement housing sector via their direct ownership of Living REIT shares.

The company’s financial outlook remains mixed. While leverage has been significantly reduced and recurring cash generation remains relatively strong, declining revenue, ongoing net losses and falling property valuations continue to present challenges. Technical indicators also remain weak, although the company’s dividend yield continues to provide some valuation support during the wind-down process.

Living REIT plc, which forms part of the consideration for the Retirement Disposal, is listed in the closed-ended funds segment of the Official List and trades on the London Stock Exchange’s Main Market. The transaction allows RESI shareholders to maintain an investment in the retirement living sector while the company continues returning capital.

RESI has stated that future cash distributions under its planned B Share Scheme will depend on retaining adequate funds to cover outstanding liabilities, transaction expenses, working capital needs, property income distribution requirements and the costs of completing its exit from the UK REIT regime.

Oracle Power PLC (LSE:ORCP) has moved closer to the development of its Northern Zone Gold Project after advancing several key permitting and regulatory activities at its Kalgoorlie Gold Project in Western Australia. The company expects to submit both its Site Clearance and Native Vegetation Clearing Permit applications this month, supported by near-complete flora, vegetation and fauna assessments.

Work is also progressing on the Mine Development and Closure Proposal, with a heritage work area clearance survey now completed and technical studies covering hydrogeology, geotechnical conditions, geology and soils approaching their final reporting stage. Oracle Power said the coordinated progress across these workstreams brings the Northern Zone project closer to the start of mining operations and represents an important milestone in transitioning the asset from development planning towards production.

While operational progress continues, Oracle Power remains a pre-revenue business and continues to report losses as it invests in project development. Ongoing cash outflows and the likelihood of future funding requirements continue to weigh on the company’s financial outlook. Technical indicators remain broadly neutral, while valuation is constrained by negative earnings and the absence of a dividend.

Sareum Holdings (LSE:SAR) has reached an important development milestone after completing dosing in the Phase 2-enabling toxicology programme for its lead drug candidate, SDC-1801. The selective oral TYK2/JAK1 inhibitor is being developed to treat autoimmune diseases, with psoriasis identified as the initial target indication. The company is now evaluating the toxicology results while continuing chemistry, manufacturing, controls and formulation activities. Sareum expects to complete the full Phase 2-enabling regulatory package during the fourth quarter of 2026 using its existing cash resources, paving the way for planned Phase 2 clinical studies and supporting the advancement of its broader pipeline in autoimmune and oncology therapies.

Despite this operational progress, Sareum remains in the clinical development stage and has yet to generate revenue. The business continues to report operating losses and cash outflows as it funds research and development, meaning future financing may be required. While technical indicators point to a positive share price trend, momentum appears elevated, suggesting the stock may be approaching overbought territory. Valuation also remains limited by negative earnings and the absence of dividend income.

South32 (LSE:S32) delivered a strong operational performance in fiscal 2026, surpassing its overall production guidance while increasing quarterly sales volumes by 15%. The higher sales helped unlock working capital and improve cash generation across the business. Production exceeded expectations across several operations, including aluminium, manganese, copper and zinc, with Sierra Gorda, Cannington and South Africa Manganese among the strongest contributors.

The company also took a significant step in reshaping its portfolio by agreeing to sell the majority of its aluminium value chain to Alcoa in a transaction with an implied enterprise value of up to $5.6 billion, in addition to rehabilitation obligations. Once the deal is completed, approximately 85% of South32’s pro forma earnings are expected to come from base and precious metals, while approved development projects are forecast to increase production by around 55%.

South32 continued to advance its long-term growth pipeline during the year. The company approved the construction of a fourth grinding line at the Sierra Gorda copper joint venture, a project expected to increase copper-equivalent production by roughly 30% from fiscal 2031. At the Hermosa development in Arizona, South32 invested approximately $710 million during fiscal 2026, progressed construction of the Taylor zinc-lead-silver mine and secured the Final Record of Decision, completing the project’s federal environmental permitting process.

Cash generation from equity-accounted investments remained strong, with the company receiving $503 million in net distributions during the year. South32 also continued returning capital to shareholders through dividends and share buybacks, distributing a combined $327 million. Although the transition of Mozal Aluminium into care and maintenance will result in one-off charges, these will be classified as significant items and excluded from underlying earnings as the company continues to prioritise operational performance and disciplined investment.

For fiscal 2026, South32 expects its underlying effective tax rate to be approximately 33%, reflecting the jurisdictions in which it operates and the associated royalty structures. The company also continued investing across its portfolio through capital expenditure, additional lease commitments and exploration activities at Hermosa, Ambler Metals and other development projects designed to support future growth in base metals.
