Research houses in dispute over merger 01 April 2020 3:37PM John Kavanagh M&A, Equity capital markets, Professional services The planned merger of two investment management research houses has hit the rocks, after Zenith Investment Partners advised Chant West Holdings that there had been a "material adverse change" in the Chant West business and it would not be proceeding with its offer.Chant West responded in a statement to the ASX that it disputed Zenith's assertion and proposed to continue with the sale.The A$12 million deal, which was announced in February, involves Chant West selling its superannuation research and consultancy business to Zenith.The research business had revenue of $6.5 million and made a pre-tax profit of $1.5 million in 2018/19.Chant West said it would retain a financial planning technology business, Enzumo, which generated $1.9 million of revenue and made a pre-tax profit of $84,000.Yesterday Chant West said it had received a letter from CW Bidco "purporting to immediately terminate the business sale agreement dated 18 February." CW Bidco is a wholly owned subsidiary of Zenith Investment Partners.Chant West said it "rejects the allegations made by CW Bidco that a material adverse change in the business has occurred. Chant West will deliver a positive EBITDA for the first half of 2019/20 and we remain confident it will continue this trend in the second half of the year."The company said it would press ahead with its shareholder meeting to approve the deal.
