Grant Thornton plans to spend about $5 billion to acquire CBIZ in what David Leary called “the largest accounting deal in over 25 years.” The combination would create the fifth-largest accounting firm in the world. Yet its expected $7.5 billion in global revenue would still be far below KPMG, the smallest Big Four firm, at nearly $40 billion.
That story is one of several reality checks in Episode 499 of The Accounting Podcast. David and co-host Blake Oliver examine how private equity, artificial intelligence, labor shortages, audit failures, cybersecurity threats, and politics are reshaping accounting.
The profession can clearly grow faster. But will its guardrails (sound integration, audit quality, data security, professional judgment, and fair tax enforcement) keep up?
Private equity can buy scale, but integration comes later
New Mountain Capital acquired a majority stake in Grant Thornton in 2024. It’s investing more money to support the CBIZ purchase. Because CBIZ is publicly traded, the deal also offers an unusual view into how the market values a large accounting firm.
The $55-per-share purchase price represents about a 54% premium over CBIZ’s 30-day weighted average. David noted that the stock began rising before the announcement and questioned how that looked with private equity involved. Blake pointed to a July letter from activist investor Reference Equity that urged CBIZ to stop repurchasing shares and return to mergers and acquisitions. That letter gave the market a public signal that a deal might be coming. It wasn’t necessarily evidence of insider activity.
The larger concern is integration. CBIZ’s earlier acquisition of Marcum cost more than expected and led to client attrition and revenue misses. Management projected only 2% to 5% growth for 2026. As Blake described the likely private equity strategy, “Package these firms up together, make them bigger, more attractive, and then go back with an IPO.”
But scale doesn’t solve the profession’s other risks.
Audit failures and cyber threats put trust at risk
The UK Financial Reporting Council fined PwC about $4.4 million for serious problems in its 2019 and 2020 audits of Babcock International Group. The regulator cited failures in professional skepticism and audit evidence involving cash pooling, goodwill impairment, and an overseas contract.
Among other issues, Babcock reported cash and overdraft balances net instead of gross. PwC didn’t identify the treatment or test whether it followed the relevant standard. The financial statements also lacked disclosures about the cash-pooling arrangements. The regulator found no dishonesty, deliberate misconduct, or recklessness, but said the audits still failed to meet professional standards.
Cybersecurity raises a related concern. The hacking group ShinyHunters claimed it breached EY and threatened to release client data. EY didn’t confirm the breach, and the hosts found no sign that data had been released after the group’s deadline. Still, the alleged access to Jira, GitHub, Azure, passwords, and sensitive client information shows the possible stakes. If attackers obtain code or credentials, they may gain paths into client systems as well.
Protecting that trust requires experienced professionals, and those professionals are hard to find.
Accounting’s missing middle is getting squeezed
Controllers and assistant controllers are the hardest finance roles to recruit, according to 44% of respondents in a 2026 talent study by Controllers Council. These jobs require technical accounting knowledge, leadership, business judgment, technology skills, and the ability to influence executives. Meanwhile, 61% of respondents reported a corporate finance and accounting talent shortage, up from 46% the prior year.
The career ladder is also flattening. According to salary data from Accounting Today, in New York, associates averaged about $105,000 while seniors averaged $108,000, a difference of only 3%. Ontario showed a similarly narrow gap. Blake suggested firms raised entry-level salaries to attract recruits without increasing senior pay at the same pace.
“The people in the middle are getting lost in this,” David said. Offshoring and AI may add more pressure to those roles, even as firms need experienced managers and controllers more than ever.
That tension makes the way firms use AI especially important.
AI should support judgment, not replace learning
A KPMG survey of more than 1,000 senior finance leaders found that AI’s biggest gains were in decision-making rather than simple efficiency. Seventy percent said AI improved decision quality, 71% reported faster decisions, and 64% cited better forecasting accuracy.
But another survey found that 39% of workers believed overreliance on AI was weakening their abilities. Among Gen Z workers, the figure rose to 46%. Half of workers said they depended on AI too much, while 30% said they couldn’t function without it.
“If you’ve never done the work, how do you evaluate the work?” Blake said, summarizing the problem. Junior professionals need to struggle with the work, make mistakes, and build the knowledge required to review AI output.
The hosts argued that businesses should connect AI agents to dependable systems they already use rather than trying to rebuild tools like QuickBooks, Bill.com, or PandaDoc. Blake’s priority is using AI first to improve services and revenue, second to avoid unnecessary hiring, and only then to reduce software costs.
The same need for guardrails extends beyond firms and into tax enforcement.
Tax rules lose credibility when enforcement looks uneven
President Trump said he might withdraw Todd Blanche’s nomination for attorney general rather than accept written limits on a disputed IRS settlement. Senators John Cornyn and Thom Tillis wanted its immunity provisions limited to IRS enforcement and excluded from Justice Department matters. Blanche also testified that he initially did not know who drafted the broad language he signed.
Trump appealed after U.S. District Judge Kathleen Williams found that the settlement had “no viable basis in law or fact” and barred its use in future proceedings. David offered an alternative: If the Trump family won’t face IRS audits, publish the tax returns and let the public review them.
Growth needs guardrails
The profession can’t measure progress only through revenue, deal size, speed, or headcount savings. The Grant Thornton–CBIZ deal shows the challenge of integrating firms under private equity. PwC’s fine and the alleged EY breach show the risks to audit quality and client data. The talent and AI stories show why firms must keep developing human judgment.
