‘Bringing together two firms with more than a billion dollars in revenue each has never been done before. There’s never been a merger of equals of firms this size,’ says Perkins Coie managing partner Bill Malley of the firm’s recently announced plans to merge with Ashurst.
The proposed tie-up – which is set to go live in mid-2026, subject to a successful partner vote in spring – marks the end of a decades-long quest for a US merger by Ashurst.
Against this backdrop, it is unsurprising that Ashurst CEO Paul Jenkins, who is set to become global co-CEO of Ashurst Perkins Coie with Malley, is relishing the slickly announced success of the pair’s merger plans.
‘Discussions started in February, and we’ve had a rapport from day one,’ he tells Legal Business. ‘We’re excited to be creating a top 20 global firm with nearly 1,000 partners. Cultural affinity and shared values are really the linchpins of any strong combination, and we believe we have that here.’
The pair are betting on a three-pronged sector focus centred around financial services, energy & infrastructure, and technology – aiming to leverage not only the client base and practice strength of both firms, but also their willingness to embrace AI and new technologies.
‘We see ourselves at the forefront of the legal industry in terms of innovation,’ says Jenkins, referencing Ashurst Advance and the firm’s AI adoption as evidence, before pointing to synergies with Perkins.
‘We’ve always been future-focused, embracing innovation and the practice of law,’ adds Malley. ‘We think it’s especially important at the moment, as AI transforms the way legal services are delivered.’
Should the union proceed, the combined firm will have revenues of nearly $2.7bn and 52 offices worldwide, including bases in 17 cities across the US.
However, before the deal can go live, the pair will need to completely convince their own firms that they have each found the right partner, a task they will begin swiftly through a series of roadshows to partners around the world.
They will also have to convince clients and the market, warding off any potential questions over it not being a Wall Street-centric deal, given Perkins has its roots in Seattle.
In the eyes of at least one former Ashurst partner, it should be an easy sell. ‘Everyone wants a US merger, so congratulations to them,’ he says. ‘It wasn’t going to be achievable to get a Wall Street firm with a big capital markets or M&A practice.’
Ashurst has infamously tried to secure such a merger before, with Jenkins’ management predecessors having talked to everyone from Latham & Watkins and Fried Frank to Sidley and Shearman & Sterling over the years.
Perkins may not be of the same scale or market position, but it does have 120 lawyers, including almost 50 partners, in New York – and reaction to the combination so far has been broadly positive.
Many point to Jenkins’ role in turning around Ashurst’s fortunes following a run of partner departures and falling revenues in the wake of its merger with Blake Dawson in the early 2010s.
In the nine years since Jenkins took up his leadership role, the Anglo-Australian firm has more than doubled its revenue, breaking the £1bn mark for the first time in 2024-25. Meanwhile, PEP has climbed to $1.77m, not far off Perkins’ figure of just under $1.9m, supporting the firms’ claim that the deal is a merger of equals.
‘Paul has done an amazing job given where they were 10 years ago,’ says Freddie Lawson, who heads the partner practice at Montresor Legal Recruitment. ‘Ashurst was being chipped away, but he has done a good job in keeping an energy and infrastructure focus to the firm. His bravery can only be applauded.’
A partner from a rival London firm adds: ‘On paper they have similar scale, profitability and turnover, so I think it will be an interesting and beneficial transaction.’
‘It’s a merger of equals, but some people are more equal than others’
Over in Los Angeles, Howard Cohl, a partner at Major Lindsey & Africa, is also positive. ‘The legal landscape is becoming very competitive, with the influx of AI and a war for talent. There aren’t many ways to really move the needle, but a large combination is certainly one.’ In the context of UK firms increasingly looking toward the lucrative US market, ‘this makes eminently good sense,’ he continues.
But it isn’t just about economic alignment. Also in California, Kent Zimmerman at the Zeughauser Group, who has been advising Ashurst throughout the merger discussions, says: ‘When Paul asked us to evaluate and advise on this opportunity, what quickly stood out was the level of strategic and cultural alignment. That alignment created a solid foundation for what is coming to fruition. This is a transformational achievement for both firms at a moment of change for the industry.’
What each firm gains from the deal is clear. In addition to its long-sought US presence, Ashurst gains exposure to Perkins’ tech practice and client base, which includes the likes of Apple alongside more emerging names. Perkins, meanwhile, benefits from Ashurst’s energy and infrastructure practice as well as gaining a global platform. When the deal goes live, building up in energy and financial services in the US and technology outside the US will be priorities.
Crucially, the consolidation will also give the combined firm greater weight to invest in both talent and technology.
As one London partner says of Perkins: ‘They have been around a long time and have worked with a strong corporate client base like Boeing and Apple.’
But, as Saul Gamoran of Seattle-based Gamoran Legal Consulting says: ‘they were struggling to compete with the biggest of the biggest. This will make them a 3,000-lawyer firm, with worldwide breadth, and the capacity and ability to take on the largest cases and the largest matters.’
Despite the largely positive market reaction, integrating practices, geographic identities and routine operations – including shifting to a calendar financial year, cash accounting system and coming up with a combined compensation system – will be no easy feat.
Another former Ashurst partner warns that management will need to avoid getting too distracted in order to be successful.
‘Any firm which goes through phases of inorganic growth will be tied up with this for a number of years and leadership will, unquestionably, have reduced bandwidth to meet other challenges that are not necessarily solved through scale like technology.’
Others question the extent to which the merger will really prove to be a merger of equals, warning that cuts could lie ahead. ‘The term gives an implicit assurance to partners that there will be parity of treatment, but this could make them hostage to fortune,’ warns one former Ashurst partner.
Another concludes: ‘It’s a merger of equals, but some people are more equal than others, as the old saying goes.’

Utilising firmwide platforms has become increasingly important for maintaining activity, as Latham & Watkins partner Pamela Reddy (pictured) explains. ‘We have really deep relationships with corporate counsel – if they have an issue, they’ll pick up the phone to their trusted adviser.’ In her view, these ties generate enforcement work with agencies such as the SFO or the CPS, but also filler work, such as due diligence for major deals.
‘The SFO has lawyers, accountants and investigators working [together] for the prosecutors – you should have the same for the defence,’ Sprenger (pictured) says.
