Construction and engineering group CRH is the biggest home-grown Irish exporter with a turnover of €23.6 billion.
The figures come from the list of the top 150 'born in Ireland' exporting companies published by Investec Bank and the Irish Exporters Association.
The companies have a combined turnover of just under €140 billion, of which the consumer goods and agri foods and drinks industry accounts for about 30%.
CRH is followed by the utilities company DCC with a turnover of €14.5 billion, and Irish Distillers Pernod Ricard in third place with a turnover of €8.5 billion.
Other companies in the Top 10 on the list include Smurfit Kappa (4), Ryanair (5), and Bank of Ireland (9).
The analysis also shows the majority (87) of companies within the Top 150 are primarily Dublin-based.
Outside of Dublin, Cork is the second most prominent county in the table both in the quantum of entries and the accumulated turnover – with 15 companies featured with a combined turnover of €7.5 billion.
The strength of Cork’s performance in the rankings has contributed to Munster being more dominant than the Leinster counties (when Dublin is excluded), with a total of 25 companies featured in Munster with a turnover of those companies topping €15 billion.
This compares to Leinster’s 21 companies with a total turnover of €12 billion.
Meanwhile, Connaught counties were represented 11 times, with the three Ulster counties in the Republic of Ireland holding six entries in the Top 150.
Commenting on the report, Head of Treasury at Investec Aisling Dodgson said: “With combined turnover exceeding €140 billion, the analysis demonstrates the true scale of Irish businesses which we classify as ‘Born in Ireland’ – companies with their origin in the country which either have grown on the back of serving the domestic market, through exports or by growing their business serving markets beyond our shores.”
