Why float the “we may delist” message—even if they never do?5 Nov 2025 12:46
1. Negotiating leverage for funding. Signalling a credible path to go private pressures current and prospective investors to step up (e.g., cornerstone in a financing) or risk losing public-market liquidity. The RNS frames AIM as costly/inefficient for them—classic setup for tougher terms with public investors and softer terms from a strategic/private backer. 
2. MAR compliance + option preservation. Once a board formally considers delisting, it’s potentially inside information; disclosing it keeps them clean while preserving flexibility to proceed if support firms up. The RNS explicitly notes the Rule 41 mechanics (75% vote), which is a tell that they’re preparing the ground. 
3. Price-setting & feedback loop. “We might delist” often flushes out real demand: boards watch the share reaction, inbound calls, and shareholder feedback before committing to a timetable or circular. Media coverage immediately amplified the message (AIM “winners & losers”, Proactive, Reuters). 
4. Strategic deal signalling. Going private can simplify a strategic partnership, minority investment or sale—especially for a U.S.-centric MedTech (Polarean’s recent U.S. distribution/installation updates reinforce that focus). Hinting at delisting can smoke out partners who prefer private-company diligence and confidentiality. 
5. Runway extension via cost cuts. Delisting removes recurring listing/admin costs and quarterly market scrutiny while they build commercial traction—this rationale is explicitly cited in their and others’ statements.
