The storms in December led to costs of €0.5m for Eir, formerly known as Eircom, to repair damage to lines.
The company said these costs will increase in the current financial quarter as many of the repair costs have been incurred since the turn of the year.
But Eir still managed to deliver revenue growth in the second quarter to the end of December, with revenues rising by 4% to €328m. This marked the third quarter of revenue growth in a row.
Earnings before interest and tax also rose by 4% to €117m while the company's operating costs were in line with the same time last year.
During the three month period, Eir announced a deal to buy Setanta Sports - a move which it described as "transformational" for the company.
The company's chief financial officer Huib Costemans said that Eir was on track to deliver low single digit bottom line growth in percentage terms for the full financial year.
Eir said its broadband connections rose by 19,000 in the quarter to reach a total of 817,000, adding that 44% of network broadband connections are high speed broadband.
The company also said that its mobile base now stands at 1,091,000. It noted that it had seen 25,000 net additions in the higher value postpaid segment since June 2015 and postpaid customers now account for 46% of its overall base.
The pre-paid customer base decreased by 13,000 in the quarter to 591,000 customers.
Its television offering now has 45,000 customers, while the number of consumers buying its triple and quad-play bundles increased during the three month period.
Eir CEO Richard Moat said the company had delivered a "strong set of results", adding that its network investment is continuing as planned.
"We remain fully committed and on target to deliver our promise to reach 1.9 million premises by 2020, may of which will have access to speeds of up to 1,000 MB/s," Mr Moat added.
