ASP Isotopes jumps 15.7% on Silicon-28 restart; Energy and Chemicals lead Tuesday

The JSE closed marginally lower on Tuesday, with the All Share down 0.15% and the Top 40 falling 0.2%, as a sharp divergence between sectors dominated the session. Energy and Chemicals were the day's standout performers, climbing 3.37% and 4.93% respectively, while Technology retreated 2.43% and the broader Industrials index fell 1.3%. ASP Isotopes rallied 15.7% to R111.19 after confirming the successful restart of 18 stages at its Pretoria Silicon-28 enrichment facility, while Thungela Resources gained 8.66% and Sasol climbed 5.85%, all on strong energy-sector momentum. Datatec fell 7.95% despite reporting exceptional full-year results, illustrating the persistent valuation discount the market applies to its conglomerate structure.

ISO ASP Isotopes restarts Silicon-28 facility, Q3 shipment target intact

ASP Isotopes confirmed on Tuesday that it has successfully restarted the first 18 stages of its Pretoria-based Silicon-28 enrichment facility after nine months of engineering modifications to resolve original equipment manufacturer component failures. The restart validates the recent fixes and keeps the group on track for commercial shipments in Q3 2026 to three existing customers in quantum computing and semiconductor markets.

The company reaffirmed its target to commence commercial shipments by the third quarter of this year, underpinned by three existing customer contracts. Management highlighted next-generation semiconductor and quantum computing applications as the primary demand drivers for its enriched silicon output.

Investors should note, however, that execution risk remains elevated as the engineering solutions must still be applied to the remaining facility stages before full commercial production is achieved. ASP Isotopes issued the restart announcement via SENS, with the stock climbing 15.7% to close at R111.19 on the day.

SSK Stefanutti Stocks exits restructuring with 229% HEPS surge and doubled order book

Stefanutti Stocks formally terminated its Restructuring Plan on Tuesday after an R580 million settlement from Eskom relating to the Kusile power station dispute enabled aggressive debt reduction. The settlement allowed the group to pay down its new Standard Bank facility from R850 million to just R223 million, dramatically improving its balance sheet position and marking a definitive turning point for the construction group.

Headline earnings per share surged 229% to 359.26 cents for the year ended February 2026, driven in part by the non-recurring Kusile settlement contribution of R492 million to profit after tax. The group secured a new R850 million facility, which replaced the historic loan and formally exited the restructuring framework.

The order book doubled to R17.2 billion, providing significant long-term revenue visibility with R8.5 billion scheduled for execution beyond February 2027. Despite the positive momentum, the group remains in a net current liability position of R133 million and has maintained a zero-dividend policy, indicating that capital preservation and debt reduction remain the priority over shareholder distributions.

DTC Datatec reports 56.5% HEPS surge and 12.5% dividend hike despite share price weakness

Datatec delivered exceptional full-year results for the year ended February 2026, with headline earnings per share climbing 56.5% to 39.9 US cents and the board declaring a final dividend of 225 ZAR cents per share, representing a 12.5% increase on the prior year. IFRS profit after tax rose 55.1% to US$91.8 million and adjusted EBITDA grew 17.8% to US$290.1 million, driven by strong operational execution and cyber expansion at Westcon International.

The balance sheet also improved meaningfully, with net debt declining 10.4% to US$46.7 million and net asset value rising 3.7% to US$540.3 million. However, the share price fell 7.95% to R79 on the day, a rare bearish divergence in response to strong results.

The weakness appears linked to a US$87.7 million prior-year revenue restatement for Westcon International and management's acknowledgment of a persistent valuation gap between the group's share price and the inherent value of its subsidiaries. The valuation discount remains under strategic review and continues to weigh on investor sentiment despite the robust bottom-line performance.

HCI HCI restructures South African oil and gas interests alongside new partner Meren Energy

Hosken Consolidated Investments announced on Tuesday an agreement with Meren Energy Inc. to restructure its South African oil and gas assets held via a 51.6% stake in Impact Oil and Gas Limited. The transaction signals ongoing portfolio optimisation within HCI's energy segment, though the SENS announcement functions primarily as a reference notice directing shareholders to an external update for material transaction information.

The restructuring announcement was accompanied by reviewed annual financial statements for the year ended March 2026, alongside a cash dividend declaration for the period. Both announcements were published via SENS, with the share price advancing 5.57% to R179.99 on the day.

Shareholders relying solely on the SENS filing for transaction economics may find the standalone informational value limited, as key financial terms and valuation impacts are housed in the external link rather than disclosed directly within the announcement body. The strategic intent is positive, but the structural opacity of the filing requires further review outside of SENS.

PPH Pepkor posts 12.1% earnings growth and progresses bank application amid cautious outlook

Pepkor Holdings reported a 13.2% increase in group revenue to R54.8 billion and a 12.1% rise in normalised headline earnings per share for the first half of the financial year, driven by strong growth in its financial services segment and robust cash generation. Cash generated from operations rose 15.1% to R4.1 billion, reflecting the underlying cash conversion strength of the portfolio.

The group is actively advancing its fintech strategy, having completed its section 16 application to establish a bank. The financial services segment continues to provide an expanding earnings contribution, supporting the overall double-digit earnings growth achieved during the period.

However, core retail operating margins compressed during the half, and management maintained a cautious outlook for the remainder of the year, noting expectations of continued challenging trading conditions. South African retail investors should also note that recent performance was materially supported by non-recurring consumer spending driven by the two-pot retirement system, which may not persist at current levels going forward.

CML Coronation interim HEPS falls 5% as SARS matter clouds operational comparisons

Coronation Fund Managers reported mixed interim results for the period ended March 2026, with basic earnings per share rising 6% to 218.0 cents but headline earnings per share declining 5% to 195.1 cents. Revenue grew 3% to R2,088 million, and management's preferred operational metric, fund management earnings per share, increased 2% to 203.7 cents. The company declared an interim dividend of 203.0 cents per share, slightly above the prior year.

The share price fell 4.36% to R43.66 on the day, reflecting investor concern over the near-100% payout ratio implied by the dividend relative to headline earnings. The company used pro forma financial information to exclude the ongoing SARS matter from certain metrics, highlighting that a regulatory or tax risk continues to obscure clean operational comparisons for the period.

The near-100% payout ratio leaves very little headroom if operational pressures persist into the second half, though the maintained dividend provides income investors with a yield cushion at current share price levels. The short-form announcement does not quantify the specific financial impact of the excluded SARS matter within its body.

ZZD Zeda hikes interim dividend 45.5% and reduces debt despite margin compression

Zeda reported a 6.1% increase in interim headline earnings per share to 201.2 cents, underpinned by an 8.9% reduction in finance costs and R31 million in expected credit loss releases. The group hiked its interim dividend by 45.5% to 80 cents per share, signalling strong management confidence in cash generation, though operating profit declined slightly by 0.6% to R841 million as margins compressed from 15.8% to 15.2%.

Net debt was reduced to R6,240 million from R6,379 million, demonstrating effective balance sheet management during a fleet expansion cycle. Return on invested capital of 12.3% comfortably exceeded the group's weighted average cost of capital at 10.8%, confirming efficient capital allocation.

Management explicitly warned of macroeconomic headwinds, noting that supply-side constraints and rising fuel prices threaten future profitability through higher inflation and interest rate pressures. The risk-to-lease ratio also shifted from 78:22 to 72:28, introducing heightened residual value risk as higher-value vehicles with challenging end-of-lease values were added to the fleet.

What we are watching

Looking ahead, HCI is expected to publish its full reviewed annual results and provide a detailed update on the Meren Energy transaction, while Wesizwe Platinum is scheduled to release its delayed Integrated Annual Report on or around 5 June 2026 following Tuesday's administrative postponement. Santova's AGM notice was also published on Tuesday, inviting shareholders to review the audited results that showed a 6.4% decline in headline earnings despite the Seabourne acquisition driving an 88.3% revenue surge.
