One of the most anticipated vacancies in Australian banking was formally closed yesterday when ANZ announced that senior investment banker and corporate adviser, Michelle Jablko, is to be its next chief financial officer. She will have responsibility for all aspects of finance across the group, as well as treasury, mergers and acquisitions and investor relations.Jablko, a merger and acquisitions specialist for almost her entire professional career, will move to ANZ from investment bank Greenhill & Co, where she had been managing director and co-head of its Australian business since 2014. New York headquartered Greenhill & Co Inc said its remaining co-head for Australia, Roger Feletto, would now become the sole leader of the business here.Prior to taking on the leadership role at Greenhill & Co, Jablko was at UBS Australia for 13 years, ending as managing director, working on "complex mergers and acquisitions for clients across a variety of industry sectors, including financial services, media, transport, resources, gaming, industrials, consumer products and retail," according to her Greenhill corporate profile, compiled by Bloomberg.She commenced her career as a lawyer at Arthur Robinson & Hedderwicks (now Allens Linklaters) where she specialised in M&A, banking and finance law. At both Greenhill and UBS, Jablko was, according to the ANZ announcement, "a strategic advisor to large Australian companies on strategy, M&A and capital markets across a range of sectors including financial services." Jablko will be based in ANZ's Melbourne headquarters from 18 July, reporting to group CEO Shayne Elliott, who is also a former ANZ CFO. Yesterday, he said Jablko's experience at Greenhill and UBS "means she is strongly qualified to lead what is a broad strategic, financial and business role at the bank."ANZ said that Graham Hodges, currently acting chief financial officer, would now turn his full attention back to his deputy chief executive officer role, with responsibility for ANZ's banking partnerships in Indonesia, Malaysia, China and the Philippines.
