WTW posted a 4% rise in revenue to $US9 billion ($12.6 billion) last year, and says the results don’t reflect the potential of the business and the “best is yet to come”.

CEO Carl Hess, who has been in the role around six weeks after three decades at WTW, says the overall results “aligned with expectations” and included an anticipated delayed impact of disruptions.

"To be crystal clear, they do not reflect the near- and long-term potential of this company to drive organic growth and margin expansion,” Mr Hess said.

“The company is well positioned to capitalise on the opportunities that lie ahead. I look forward to reinvigorating growth and to successfully executing our transformation plan. I am confident the best is yet to come.”

WTW completed the sale of Willis Re in December and recorded a one-off gain of $US2.3 billion ($3.22 billion). From the start of 2022, the structure of WTW changed from four segments to two: Risk and Broking and Health, Wealth and Career.

“We're encouraged by the progress we're making on our strategic initiatives. While we have hard work ahead of us in 2022, we're kicking things off with renewed energy and conviction,” Mr Hess said.

WTW says its clients are striving to create “continuity and clarity” in an environment of ongoing disruption and as the frequency and complexity of threats continue to increase due to geopolitics, economic volatility, population health, climate change, supply chain, talent and technology.

Its Corporate Risk & Broking segment recorded a jump in international's revenue of 10%, helped by a strong performance in M&A in Australasia.
