Sam Mills joins Grant Thornton as turnaround partner.

Sam Mills joins Grant Thornton as turnaround partner. 18 September 2026 Consultancy.uk Sam Mills joins Grant Thornton as a turnaround and restructuring partner. He brings two decades of restructuring and turnaround expertise to the firm's advisory team. "This is a great time to join the Grant Thornton turnaround and restructuring team with such a strong reputation for delivering high-quality work at pace," said Mills. "I'm drawn to the firm's growth ambitions and its tech-enabled approach to client delivery, which I think will make a real difference for clients and colleagues alike." With more than 500 professionals across its Manchester and Liverpool offices, Grant Thornton's North West team remains a priority growth market for the firm. Mills' arrival reflects this, as the Manchester-based professional is the third senior appointment in the region in as many months. Mills also joins a growing national turnaround and restructuring practice, following the other recent appointments of David Pike as head of London, Ian Guthrie as head of real estate advisory, and Nick Toone in its value creation and turnaround team. Kevin Coates, Grant Thorton's UK head of turnaround and restructuring, added, "We are delighted that Sam has joined the firm at such an exciting time in the firm's growth story. Sam has spent two decades helping CFOs and boards at the point where decisions actually matter, and that experience will strengthen how we support clients through periods of stress and fast-paced turnaround." As a qualified chartered accountant (ACA), Mills has held leadership roles in the Big Four, as well as senior finance roles in industry and a number of secondment positions with high-profile clients. His varied experience has given him a rounded, practical perspective on the pressures facing management teams during periods of change. Pete Terry, Grant Thornton's practice lead for the North West of the UK, concluded, "Sam brings deep, hands-on restructuring experience and a track record of supporting businesses and their stakeholders through complex, high-pressure situations. His appointment reflects the scale of our ambition in the North West: building a team that understands the full spectrum of financial and operational challenge."

Grant Thornton CBIZ deal valued at $5bn in all-cash takeover.

Grant Thornton CBIZ deal valued at $5bn in all-cash takeover. The Grant Thornton CBIZ deal, announced on 29 July 2026, will hand shareholders of the New York-listed management consultancy $55 per share in cash, a 54 per cent premium to the company's 30-day average share price. The transaction, expected to close in the fourth quarter of 2026, would create the fifth-largest professional services, tax, and advisory firm in the US. The merger agreement was signed on 28 July 2026 and is structured as a three-party arrangement among CBIZ, Viking ParentCo, Inc. and Viking MergerCo, Inc., a wholly owned subsidiary of Viking ParentCo, according to CBIZ's 8-K filing with the Securities and Exchange Commission (SEC). Viking MergerCo will merge into CBIZ, which will cease to be publicly traded upon closing. CBIZ's share price fell nearly 40 per cent over the prior year, hitting a low of $24.29 in April. At $55 per share, the offer represents a substantial recovery for investors who held through that decline. Go-shop period and shareholder protections in the Grant Thornton CBIZ deal. The merger agreement includes a go-shop provision, permitting CBIZ and its advisers to solicit and negotiate rival bids until 11:59 p.m. Eastern Time on 27 August 2026, according to CBIZ's investor relations filing. Prior to the shareholder vote, the CBIZ board retains the right to terminate the agreement in favour of a superior proposal, subject to payment of a termination fee. Concurrently, Grant Thornton Advisors LLC entered into a limited guarantee with CBIZ covering the parent termination fee and certain reimbursement obligations that may be owed by Viking ParentCo, the 8-K filing discloses. The combined entity would generate nearly $7.5bn in revenue and operate across more than 20 countries, propelling Grant Thornton past mid-market rivals including RSM and BDO in the US rankings. New Mountain Capital and the insurance spinoff. Private equity firm New Mountain Capital, which has approximately $60bn in assets under management according to PLANADVISER, first invested in Grant Thornton Advisors in May 2024 to fund the firm's growth strategy. It is now contributing incremental equity to support the CBIZ acquisition, per the joint press release filed with the SEC. Bob Mulcare and Sean Donovan, managing directors at New Mountain Capital, are leading the transaction. Andre Moura, a further managing director at the firm, has been involved with Grant Thornton Advisors' strategic growth plan since the May 2024 investment, according to the Grant Thornton Advisors press release. As part of the deal, CBIZ's Benefits and Insurance Services segment will be separated into a standalone company, also backed by New Mountain Capital. Mulcare and Donovan described the planned entity as 'a new leading firm dedicated to insurance, retirement and payroll services,' per the joint SEC filing. The separation is driven by audit independence rules: operating an insurance brokerage within the same entity as an audit practice creates regulatory conflicts, according to Insurance Business Magazine. Carving out the benefits and insurance business removes that conflict. Jim Peko, chief executive of Grant Thornton Advisors, said the firm was 'broadening our ability to support businesses through every stage of growth, from early development to global scale.' Jerry Grisko, president and chief executive of CBIZ, said the combination would create 'a stronger firm with new and exciting opportunities for our team members and enhanced service offerings for clients, while delivering significant value to CBIZ shareholders.' CBIZ is currently the only audit firm listed on a US stock exchange. Under a change-in-control severance plan adopted alongside the merger agreement on 28 July 2026, eligible staff face qualifying terminations covered by cash severance ranging from 0.5 times to 3 times annual compensation, with health-coverage payments for between 6 and 36 months. The deal sits within a broader shift in the accountancy sector. Grant Thornton's UK arm was separately acquired by private equity firm Cinven, becoming the largest UK professional services business to accept external equity investment; the firm's UK equity partners received a £35.2m payout following that transaction. CBIZ shareholders will vote on the merger before the go-shop window closes on 27 August 2026, with deal completion targeted for the fourth quarter of 2026. Any superior proposal received before that vote could still alter the outcome.

Cardano TD Sequential turns bullish: here's the target.

Cardano TD Sequential turns bullish: here's the target. A big bullish sign emerges on the daily charts, but the SuperTrend's still lagging behind upon ADA's soft bounce. On-chain signals are starting to fall in line for Cardano (ADA) on the daily time-frame, says mainstream crypto analyst Ali Martinez. Enduring a bi-weekly correction after a double-digit rally last month, Cardano's (ADA) price managed to restore the $0.17 resistance territory along with a bullish TD Sequential signal. Cardano bulls unveil targets upon complete correction. According to Martinez, the big play here is $0.20 in the near-term. That ADA price range was last touched on August 6, 2026, when Cardano's utility-driven rally topped out. However, last week's correction had the Tom DeMark Sequential at a selling sentiment before turning bullish. That was clearly triggered by whales. During that pushback, the number of whales holding 1-10 million ADA fell from 2,370 to 2,340, making many crypto aficionados believe a bigger drawdown is coming up next. Instead, ADA found its foot at $0.158, waited a couple of days & found confirmation at the $0.17 price range. 18+ · Gambling involves risk. Play responsibly. With bulls pushing through, the path to $0.20 comes with a crucial checkpoint that's designed to flip the price trend back to bullish. Technically speaking, the next confirmation line comes at $0.188, converging with the SuperTrend's green line pictured in the chart below. With the True Strength Index (TSI) bottoming roughly three days ago, the upward convergence of blue & pink lines in this indicator would definitely harden Ali's bullish thesis if the SuperTrend price reaches the green point. Cardano's institutional game stronger than ever. The $6.5 billion valued crypto currency could also see a substantial liquidity boost once the brand new Dijkstra upgrade kicks in. The launch is divided into two campaigns: Phase one launches in Q4 2026, featuring the Linear Leios scaling solution, nested transactions, a new serialization structure & Plutus V4 changes. The other phase activates the Ouroboros Peras consensus protocol via a separate hard fork, with a target timeline of Q2 2027. With Cardano's mainnet & the Midnight side-chain becoming way more attractive to institutions. To illustrate, Grand Thorton launched On-chain financial audit attestations on Cardano this year. Meanwhile, Nasdaq included Cardano (ADA) in crypto index futures alongside Bitcoin (BTC) & Ether (ETH).

From vision to impact: creating positive value for people and nature through impact management.

From vision to impact: creating positive value for people and nature through impact management. 11 August 2026 Consultancy.nl Many organizations are looking for ways to create positive value for people and nature - think of increasing equal opportunities or making the living environment more sustainable. However, the road from vision to actual impact is long and challenging. To prevent beautiful ambitions from stalling along the way, Grant Thornton developed the Future Fit Management Model: a five-step plan for effective impact management. Making an impact is no longer reserved for charities. More and more businesses also want to demonstrably contribute to solutions for social and ecological issues. However, good intentions are only the beginning - the real challenge is to turn them into measurable results and lasting improvement. This is where impact management comes into play. Where the emphasis is often on reporting, Grant Thornton emphasizes that it is essentially about making conscious choices: "Impact management is not just about accountability. The real value lies in using insights to make better decisions and increase positive impact." To support organizations in this, the accountancy and advisory firm developed the Future Fit Management Model. This model describes impact management as a continuous cycle of five steps: vision and analysis, implementation, measuring, improving, and reporting. Organizations can enter at different points, but ultimately it is about completing the entire cycle. "Impact management is not a one-off project, but a continuous learning process in which organizations continually reflect, adjust, and improve," the researchers state. 1: vision and analysis. The first step is to formulate a clear vision. In this, as an organization, you examine which social issues align with your identity, expertise, and ambitions. You also map opportunities, risks, and relevant developments. Tools such as portfolio analysis, scenario thinking, and theories of change help make this vision concrete. 2: implementation. A vision only has value when impact becomes part of everyday practice. This requires not only support among employees, but also appropriate processes, systems, and practical tools. "By making sharp choices, a better picture emerges of what really works and where improvement is possible." Grant Thornton emphasizes that different functions within an organization need different knowledge. "For one employee, the emphasis is on impact measurements, while a board member must incorporate impact into strategic decision-making." The researchers therefore advise organizations to link impact management as much as possible to existing annual cycles and decision-making processes. This way, impact does not become a separate initiative, but an integral part of the organization. 3: measuring. Measurements provide valuable information from which organizations can learn and with which they can improve their approach. The researchers advise organizations to formulate clear learning questions in advance and to focus on a limited number of desired changes. Subsequently, appropriate research methods can be chosen, such as interviews, questionnaires, or creative measurement tools for specific target groups. "Not everything needs to be measured at once," the researchers say. "By making sharp choices, a better picture emerges of what really works and where improvement is possible." 4: improving. Perhaps the most important step in impact management is actually utilizing the collected insights. According to Grant Thornton, many organizations get stuck at collecting data, while translating results into concrete improvements yields the most social value. "Be honest about what went well, but also about what can be improved." It is therefore wise to regularly organize joint reflection sessions in which teams discuss the results, give meaning to the outcomes, and determine which improvements take priority. "It is precisely the disappointing results that often offer the greatest opportunity to learn and further increase social impact," the researchers write. 5: reporting. Only in the last step does reporting come into play. Organizations are increasingly communicating about their social impact, partly due to stricter laws and regulations and the growing need for transparency among stakeholders. Grant Thornton emphasizes that an impact report must always align with the target audience. Donors, investors, collaboration partners, and the general public all have different information needs. In addition, it is important to share not only successes, but also limitations of the research, assumptions made, and lessons learned. "Transparency increases trust," the advisory firm states. "Therefore, be honest about what went well, but also about what can still be improved." Finally: a continuous growth path. Above all, it is important to never lose sight of the goal: impact management ultimately aims to increase positive social value. This requires ongoing engagement of stakeholders, attention to future risks and opportunities, and the willingness to adjust activities when insights give cause to do so. "Those who see impact management as a continuous growth path lay the foundation for an organization that not only creates social value today, but also remains relevant and future-proof in the future," Grant Thornton concludes.
