Craigs Investment Partners broker Peter McIntyre said the profit guidance for next year was welcomed.
"The result surprised on the upside, but to get guidance from income in this uncertain environment is certainly welcome."
However, the guidance came with a caveat, as Chorus warned of regulatory uncertainty, Mr McIntyre said.
The shares climbed 26c to $3.42, the highest price since early May when the Commerce Commission indicated it wanted a lower regulated average price for some of Chorus' copper network services.
Chorus, which was split out from Telecom, reported operating earnings of $399 million for the seven months ended June.
Revenue for the period was $613 million, earnings before interest and tax came in at $210 million and the reported profit was $102 million after $40 million of tax.
The company will pay a 14.6c per share dividend. A fully imputed dividend of 25.5 cents per share was expected for 2013.
Chief executive Mark Ratcliffe said the result reflected a pleasing start to the company's busy first seven months of operations as a publicly listed company.
"We've been focused on supporting our customers during what is a period of complex industry transition, and it has been good to see their success in adding about 50,000 broadband connections to the network."
The launch of the ultra-fast broadband (UFB) network was gaining momentum, with about 57,000 end users already within reach; and Chorus was working with customers to facilitate the transition to fibre as that network continued to grow, he said.
Fibre-related capital expenditure, principally the UFB launch and Rural Broadband Initiative, accounted for 79% of Chorus' $346 million gross capital expenditure. That was within the company's guidance of $335 million to $355 million for the period.
"While fibre demand is uncertain, there are early signs that it is emerging. We've begun, for example, to see new growth in demand for our high-grade business fibre service following the introduction of UFB pricing," Mr Ratcliffe said.
While fibre prices were set and provided certainty, copper pricing remained highly uncertain at a time of significant transition for the industry and significant investment through public-private partnerships.
That meant the regulatory framework and pending regulatory processes remained central to how incentivised or aligned the industry would be in making choices that supported the Crown's UFB policy, Mr Ratcliffe said.
Of the $613 million revenue for the seven months, basic copper provided $399 million, enhanced copper $89 million, fibre $28 million, value added services $18 million, field services $47 million, infrastructure $14 million and other income $18 million.
