However,after completing its due diligence and finalising debt-funding commitments,KKR on Thursday dropped the offer price to $3.40 a share,valuing MYOB at $2 billion.
MYOB's board has informed KKR that it is not recommending the revised offer,but the companies remain in discussions.
Once the dominant provider of accounting software to small and medium-sized businesses in Australia,MYOB has been outpaced in recent years by cloud-based accounting software provider Xero.
Since KKR's initial bid in October,shares of global technology players like Facebook and Google owner Alphabet have fallen sharply amid concerns about incursions on privacy,sparking a sell-down across the broader sector.
Xero's share price has dropped from $48.84 to $38.53 amid a 10 per cent decline on the Australian sharemarket. And credit markets have raised the price of corporate debt amid expectations of a rate hike,making it more expensive for firms like KKR to carry out leveraged buyouts.
KKR declined to comment on the revised bid.
