Keys said the radiology unit performed well, increasing revenue and earnings in the first quarter.
Abano's dental strategy had been a bone of contention with the company's biggest shareholders Peter and Anya Hutson, who in conjunction in with James Reeves, had sought to take control of the firm through several takeover bids and an attempt to spill the board. Those shareholders quit their collective 19 percent stake, held in the Healthcare Partners vehicle, last month.
Chair Trevor Janes told shareholders at today's annual meeting in Auckland that the departure of those shareholders was "a significant relief for the company" ending a "protracted period of responding to a disaffected and antagonistic shareholder who has been very disruptive for the company." The stake was bought by a number of different investors on both sides of the Tasman, he said.
Abano is still pursuing the group for costs associated with the failed takeover bid.
Janes reiterated his intention to leave the board at the end of his term and said more changes are planned for the next two years.
"As our company evolves, we believe it is important for board skills to include governance expertise, financial skills, industry knowledge, an indepth understanding of the company, fresh thinking and capabilities which will add value," he said.
The shares were unchanged at $9.27 and have gained 15 per cent this year, outpacing the 10 percent increase in the S&P/NZX All Index over the same period.
