Stephen H. Nigro. How I is rewriting the playbook for modern investment banking, by John Stoy and
journalist. Stephen Nigro has experienced innovation in his career. Fax machines transmitted
hand-delivered documents, spreadsheets and mail became electronic, cell phones extended the business
date to 24 hours, and the Internet created a worldwide web of resources and communication.
He graduated from college in 1982, spent four decades in finance and investment banking,
and has watched each successive technology wave reshape how deals get done.
None of them, in his view, comes close to what is happening now.
Nigro, an investment banker and board director with decades of mergers and acquisitions,
M&A and capital raising experience, is not describing artificial intelligence, AI,
as a disruption to his profession.
He is describing it as something more significant, changing not just the speed of banking but its
fundamental approach.
I don't look at it as a disruption, Niagara states.
I look at it as a transformation, and nothing will be as transformative as this.
The process has been compressed.
Every part of it, the investment banking process, including origination, analysis and documentation,
marketing, receiving and evaluating offers, and closing, has always been time intensive
at every stage. Research that required weeks of analyst hours to produce a credible conclusion
now takes minutes. Document comparison that once consumed an afternoon is now a 10-minute task.
Nigro describes completing a comparison of a three-to-four page letter of intent against a 200-page
purchase agreement on an Amtrak trip to Washington, D.C., identifying the differences. Typically,
that time-consuming analysis was followed by communicating the differences to attorneys to incorporate
into the applicable definitive documentation. But Nigro went further, asking the AI to draft the missing
contractual provisions, and it did so complete with cross-references to other sections and relevant
definitions. The competitive advantage was real, but he knew it was temporary. Once competitors adopt the
same tools, falling behind becomes the risk for those who don't, he reflects. The applications extend
well beyond document analysis. Nigro recently used AI to generate a management discussion and analysis.
M.D. and A, from a set of financial statements, a task he once had to teach junior analysts to perform
manually. Sitting alongside an analyst as they worked through it together, NIGRO found himself in an
unfamiliar position, the elder banker urging the younger professional to lean into the technology.
Normally it's the other way around. The junior person is the one pushing the senior person
to adopt the new tool, he observes. This time, the roles were reversed, and the AI produced the
narrative faster and more precisely than traditional methods would have allowed. The triangle is
becoming a diamond. The traditional investment banking hierarchy is shaped like a triangle,
with a wide base of analysts performing the production work and a narrow tip of senior bankers
owning client relationships. Nigro believes AI will reshape that into something closer to a diamond,
elevating analysts and associates into roles requiring greater judgment, issue identification,
and decision-making rather than mechanical execution. He draws the parallel
to what happened when paper spread sheets became electronic. The analysts who once spent hours on
manual calculations were freed to focus on analytical review. The profession adapted, it will adapt
again, and the adaptation will favor people who can work alongside AI rather than those who simply
perform the tasks AI now handles faster. On due diligence, the implication is already concrete.
Nigro queried AI directly own how to improve his firm's practice and received nine specific
suggestions. One stood out, uploading a general ledger, potentially thousands of lines of data,
and having AI identify unusual journal entries and potential non-recurring items, generate a time
series profit and loss, P&L, and answer questions about the underlying data. It put us ahead,
he notes, and we're going to invest further in that capability. AI does not replace the banker.
It sits next to one. NIGRO is precise about what AI is and is not in the context of investment
banking. In his words, AI is like having the smartest and fastest associate sitting next to him,
capable, rapid, and useful. It is still an associate and does not possess the judgment, experience,
ability to handhold a client through a difficult moment, or nimbleness to respond when a deal goes
sideways in a way nobody anticipated. Those qualities remain the irreplaceable value of a seasoned banker.
AI makes that banker faster, better prepared, and more analytically capable, but the client still needs
the human at the table. The profession Nigro entered in 1982 has survived every technological
shift it has encountered. The ones who thrived were not the ones who waited to see whether
the technology was real. They were the ones who picked it up early, learned what it could do,
and adapted their practice around it before the competitive window closed. That window is open now.
The bankers who treat this moment as a transformation to engage, rather than a threat to manage,
are the ones who will still be setting the terms of the deal, not scrambling to catch up to,
someone who started two years earlier. Follow Stephen H. Nigro on LinkedIn for more insights on
investment banking, M& Advisory, and how AI is transforming the deal-making profession. This story was
