Significant shareholder meaning

What does Significant shareholder mean?
In practice, a significant shareholder is any person holding 3% or more of any class of a company’s AIM‑traded securities, with treasury shares excluded when calculating that percentage. The term is defined in the AIM Rules of the London Stock Exchange and is used consistently across England & Wales, Scotland and Northern Ireland. It also applies to Irish‑incorporated issuers admitted to AIM. This status has disclosure consequences: - Under AIM Rule 2 (Schedule One), an applicant for admission must disclose its significant shareholders in its Schedule One information. - Under AIM Rule 17, an AIM company must notify the market of any relevant changes to its significant shareholders. - Under AIM Rule 26, an AIM company’s website must include up‑to‑date details of its significant shareholders. In practice, companies and advisers monitor movements around the 3% threshold, confirm the exclusion of treasury shares when determining percentages, and keep market and website disclosures current. The expression is specific to AIM; other regimes (for example, UK Disclosure Guidance and Transparency Rules on “major holdings” or Euronext Growth Dublin) use different terminology and may apply different thresholds.

Anticipating disputes in the low-carbon hydrogen value chain: joint ventures, certification, pricing, construction, interfaces, trade, ESG and investment

Overview Hydrogen is the universe’s most plentiful chemical element and, in some uses and certain applications, yields only water at the point of use. Although the fuel itself is colourless, it is often labelled by ‘colours’ according to the production route, depending on how it is produced. Black, brown and grey hydrogen arise from coal or natural gas, with grey presently the most widespread form produced and currently the most commonly produced type. Blue hydrogen likewise originates from natural gas, but its manufacture is paired with carbon capture and storage to deliver a more carbon neutral variant. Green hydrogen, by contrast, relies on renewable electricity (for example, from solar or wind) to split water through electrolysis. Because electricity is the key input, green hydrogen sits within the so‑called ‘power‑to‑x’ world of technologies and applications which are attracting significant investment. Together, green and blue hydrogen are generally referred to as ‘low carbon hydrogen’. A closely related field showing promise is also green (and blue) ammonia as well...

UK share incentives update: Babcock investor dissent on executive pay, CIOT response to HMRC adviser registration, PAYE guidance updates for internationally mobile employees, and key dates (2 October 2025)

In this issue: Corporate governance Tax treatment HMRC Manuals tracker Dates for your diary Weekly highlights from other practice areas Corporate governance Babcock suffers investor dissent over executive pay FTSE 100–listed Babcock International Group PLC faced significant shareholder resistance to its executive remuneration at this week’s general meeting. Over 32% of votes went against the Directors’ Remuneration Policy, and more than 32% also opposed amendments to the performance share plan (PSP), though in each instance a majority of those voting backed the resolutions. Under the plans, the PSP—which delivers annual equity awards that vest after three years based on a scorecard of performance targets—would gain an additional absolute Total Shareholder Return (TSR) ‘kicker’ for awards granted from the 2026 financial year. Consequently, once the existing ‘core’ scorecard has determined vesting of the current ‘core’ opportunities (set at 250% and 200% of salary for the CEO and CFO, respectively), a further multiplier, linked to the company’s absolute TSR,...

Argentina: comprehensive business law overview for foreign investors—corporate structures, RIGI incentives, FX controls, tax, employment, competition/merger control, securities, data protection, IP, trade, immigration, renewables—November 2025 update

Updated November 2025 Introduction The Argentine Republic comprises 23 provinces plus a federal district—the City of Buenos Aires, the nation’s Federal Capital. Sitting on the south-eastern edge of South America, Argentina ranks eighth worldwide by land area and second in Latin America, spanning roughly 3.8 million square kilometres (about 1.5 million square miles). Its population exceeds 45 million, with around 15 million residing in Greater Buenos Aires, and an overall density close to 15 inhabitants per square kilometre. With a GDP near US$633bn, Argentina stands among Latin America’s biggest economies. Yet recurrent swings in growth and entrenched institutional constraints have hampered development. Although urban poverty has fallen compared with the prior year, it remains elevated at roughly 32% of residents, according to recent data. In December 2023 a new right-of-centre coalition assumed office, pledging a shift towards more market-friendly measures, such as easing foreign exchange controls, sharply cutting public expenditure, and pursuing other significant reforms. At the time of writing the government succeeded...

Life Insurance in UK Estate Planning: Funding IHT, Policy Options, Trust Structures and Tax Treatment

Overview of the use of life insurance in estate planning Life insurance—also called life assurance—often plays a significant role in estate planning. This Practice Note outlines the principal policy types offered in the market, examines how they can support an estate plan, and reviews the key tax implications. A central difficulty in many estates is finding cash to settle the inheritance tax (IHT) that arises on death where no spousal exemption is available and the estate is made up, to a meaningful degree, of hard‑to‑realise assets. These can include land, shares in a business that may fail to attract business property relief, and chattels, for example works of art that fall outside the conditional exemption regime. Although IHT instalment property relief can, for illiquid assets, allow the liability to be spread over ten years with interest charged, the obligation to pay IHT remains, and releasing sufficient liquid funds can be problematic. Life insurance can, on death, provide immediate liquidity to meet the IHT liability...
