Grainger chief executive Dame Helen Gordon says she is unruffled after two high-profile activist investors acquired significant stakes in the FTSE 250 residential property group.
High Street tycoon Mike Ashley controls around 4 per cent of the business after securing department store chain Harvey Nichols in a £40 million rescue deal last week. US corporate raider Boaz Weinstein built a 5 per cent stake earlier this summer through his investment vehicle Saba Capital Management.
Weinstein has spent the past two years targeting investment trusts, attempting with some success to unseat boards and seize control. He is now laying siege to real estate investment trusts, or REITs, including Grainger.

Gordon appears unbothered by the arrival of the pair on her shareholder register, having managed activist pressure when she assumed control of the company a decade ago.
When she took over as chief executive of Grainger 10 years ago, she was confronted by activist investor Richard Bernstein of Crystal Amber. Bernstein urged Grainger to perform a quick sale of properties let at below-market rents to tenants holding lifelong residency rights.
Gordon rejected that strategy and instead shifted the business into build-to-rent housing, constructing high-quality rental homes to secure a long-term stream of income. "I thought: I can be more active than the activist can ever imagine," she said.
A decade later, FTSE 250-listed Grainger stands as the UK's largest quoted residential landlord. The company manages 11,200 rental homes, including the Argo Apartments complex in Canning Town, east London.
Share Discount and Takeover Threats
Like other property groups, Grainger shares trade at a 40 per cent discount to the net value of its assets, creating an opening for corporate raiders and activist funds.
Gordon insisted she remains open to discussions with any major investor. "Any shareholder in the company has a voice worth listening to," she said. "If they have a good idea I have missed as to how I can narrow the discount, I am really all ears."
She confirmed she reached out to Weinstein without receiving a response, but noted productive talks with Ashley. "We have met Mike Ashley’s team and it was really positive," she said.

Threats of takeover extend across the broader real estate investment trust sector. Segro, the largest listed property trust in the UK, recently capitulated to a takeover bid from US competitor Prologis.
Industry observers fear that selling listed property trusts to overseas buyers and private equity firms could harm national infrastructure. Segro builds data centres essential for artificial intelligence development, other property trusts house vulnerable or elderly adults, and Grainger provides housing for NHS staff, who account for 30 per cent of its tenants.
Gordon expressed concern over foreign acquisitions of vital domestic assets. "Perhaps if you are a REIT owned by an overseas owner they may not be thinking about the fabric of the UK," she said. She added that while she understands why the Segro deal occurred, it remains "a great shame".
Career History and Crisis Management
Gordon, who was made a dame in the King's Birthday Honours list this year, is now 67. She began her property career in the 1980s after developing an interest in construction at age three while playing on the site of her parents' home in Cheshire.
She worked on the expansion of Milton Keynes in the early 1980s before joining infrastructure firm John Laing. There she directed the UK's first Private Finance Initiative building project at Ashford International railway station in Kent.
While at John Laing, she questioned whether the firm would appoint a female director. "It was unusual to be a woman in that world at the time," she said. "I asked the chief executive, who was a member of the Laing family, if they would consider making a woman a director and the answer came, 'well I do have a daughter'."
Gordon went on to become the company's first female director before holding senior roles at Railtrack, where she was present during its renationalisation. She later managed a flagship investment fund at insurance giant Legal & General.
Following the 2008 global financial crisis, she managed the liquidation of Royal Bank of Scotland's £38 billion international property portfolio. "It put other challenges in perspective, absolutely," she said.
She was contemplating stepping back from executive work in her late 50s when a headhunter approached her to lead Grainger, a firm founded in 1912 by a wealthy family in Newcastle-upon-Tyne and named after the city's Grainger Town district.
Rental Market Operations and Expansion
Grainger aims to challenge traditional perceptions of dingy, cramped rental flats by offering premium accommodation priced accordingly. At Argo Apartments, facilities include a 24-hour concierge desk, a gym, dedicated workspaces, guest suites, and a private dining room for events. Furnished two-bedroom apartments start at £2,300 per month.
Gordon argues that high-quality rental properties fulfil critical social and economic functions by reducing reliance on early home ownership. "In other countries people rent for longer," she said. "If people in this country knew prices were not going to race away and there was decent quality rented accommodation you might buy later in life."
She added that rental housing drives regional economic growth by attracting skilled workers. "It is a key to attracting and keeping talented people in an area. Look at Manchester. A large proportion of graduates stay for a time because there is a massive rental market," she said.
Grainger operates across 22 UK cities with strong tenant demand, including London, Manchester, Bristol, Oxford, and Derby, where engineering graduates frequently prefer modern apartment rentals to buying terraced houses.
She encourages individual private investors to buy shares in Grainger as a straightforward alternative to direct buy-to-let property ownership.

Valuation Gap and Regulatory Environment
While Grainger's share price has dropped 20 per cent during Gordon's ten years in charge, the total return with reinvested dividends stands at 14.6 per cent.
Gordon argued that equity markets unfairly reward speculative technology companies while discounting asset-backed dividend payers. "Tech firms are seen as a central component of the AI boom but we are a central component of life in a country with a housing shortage," she said.
She described the Renters' Rights Act introduced under the Labour government this year as beneficial for Grainger, predicting that stricter standards will drive smaller private landlords out of the market.
However, she criticized political turnover in housing policy. "One problem is just the carousel of housing ministers. We have had 17 in 12 years," she said.
Having outlasted 17 housing ministers, the collapse of Railtrack, and the £38 billion property sell-off at RBS, Gordon remains unperturbed as new activist investors test her position.
