It's not every day you see a former CIA spymaster turn up on the board of a tiny AIM-listed port company, but that's exactly what happened at Mercantile Ports and Logistics Ltd (LSE:MPL) this week, and the market has noticed.
Shares have rocketed 312% over the past seven days after the company appointed Marty Martin, a veteran of roughly three decades in the US intelligence community who served as CIA chief of station for the Near East Division, to its board.
The appointment, subject to regulatory approval, comes as MPL signals it is looking beyond India for strategic opportunities in jurisdictions with greater transparency for international investors. That's a notable shift for a company whose main asset is a port facility in Navi Mumbai.
MPL has been fighting a legal battle over that very asset, having challenged a creditors' committee decision to approve a resolution plan for its Karanja Terminal subsidiary that the company says was fundamentally flawed. Mumbai's insolvency court has issued notice in the proceedings, with a hearing listed for 8 June.
Managing director Pavan Bakhshi said Martin's international strategic experience would be invaluable as MPL evaluates opportunities outside India while continuing to fight for its existing asset base.
Quite what a former spy chief brings to a micro-cap port stock is open to interpretation, but the market clearly likes the intrigue.
AIM's winning streak comes to an end
Turning to the wider market, AIM broke its winning streak to end the week 0.6% lower as the Starmer drama playing out in Downing Street filtered down to the small-cap market. It underperformed its benchmark, the FTSE 100, which was off 0.3%, though the real volatility was to be seen in the gilts market amid chaos in the Labour ranks over whether the PM should go and who should succeed him.
Cordel snapped up by Germany's Vossloh
Sticking with the winners, Cordel Group PLC (AIM:CRDL) almost doubled in value after Germany's Vossloh announced it had reached agreement to acquire the UK-based rail technology firm for £29 million.
Bradda Head Lithium Ltd (AIM:BHL, OTC:BHLIF, TSX-V:BHLI, FRA:8CD1) rose 74% after it signed a memorandum of understanding with Tyfast Energy to explore a US-based lithium supply route for Tyfast's next-generation battery anodes.
Metals One PLC (AIM:MET1, FRA:HT7, OTCQB:MTOPF) was up 50% on Friday after the critical metals developer expanded its agreement with DISA Technologies to evaluate and potentially treat abandoned uranium mine waste dumps at its Uravan Belt project in Colorado.
Rome Resources Plc (AIM:RMR, FRA:33R) was up 9% after stockbroker Allenby Capital lifted its implied valuation to around $146 million, up from $100 million, on the back of progress at the Bisie North tin project and a run of encouraging drilling results in the Democratic Republic of Congo.
The uplift reflects Rome's intention to increase its interest in Bisie North from around 51% to 73%, giving the AIM-listed explorer a larger share of any future resource growth. Allenby's revised valuation equates to 1.31p per share against a current price of 0.44p.
A tough week for the fallers
Down 30%, Engage XR Holdings PLC (AIM:EXR) was the week's biggest loser after the spatial computing group reported a sharp drop in revenues, hit by delays to contract signings and weaker demand from corporate clients.
Also off 30% was Microlise Group PLC (AIM:SAAS) after the software minnow unveiled a mixed full-year report card. Sales rose and cash generation was strong, but profits fell as weaker OEM demand and delayed contract wins weighed on margins. The update came with a warning that 2026 revenues would be slightly below market expectations.
ValiRx ended the week 25% lower after unveiling a fundraiser that will bring in around £1.2 million of new investment, a sum almost equivalent to its current market value. The group, which specialises in cancer research and women's health, said the proceeds will go towards in-licensing, intellectual property expansion, preclinical development and the growth of its animal health division.
One for the watch-list
And finally, if lithium tickles your fancy, Fox-Davies Capital has slapped a speculative buy and 22p target on CleanTech Lithium PLC (AIM:CTL), the Chilean brine developer currently trading at just 8p.
The broker reckons the stock is deeply undervalued after two big milestones: the agreement of a 40-year special lithium operating contract with the Chilean government, and a pre-feasibility study confirming robust economics at the flagship Laguna Verde project.
