Co Clare engineering company Mincon said its operating profit for the year to the end of December rose by 16% to more than €16.3m.
Revenues for the year rose by 21% to almost €117.7m as the company noted that sales of its own manufactured products exceeded €100m for the first time.
During the year, the company bought the Driconeq Group, which while a large lower margin business was a "great fit" for Mincon as a drill pipe manufacturer.
Mincon said it does not expect acquisitions to add much to profitability in their first year due to higher costs, but added that it expects to improve the gross and net margins in the year ahead.
The company's chief executive Joseph Purcell said that trading in the new year to date has been "fitful and flat".
"However we have significant opportunities to realise over the coming months, including the roll out in construction piling and large hammers and the commercialisation of the Greenhammer systems," he added.
