Datacom, New Zealand's largest domestically owned information technology firm, has reported a significant contraction in profitability, with net profit halving year-on-year.

The decline occurred even as the company's top-line revenue increased, signaling a divergence between sales growth and margin expansion amid a challenging operating environment for the sector.

Beyond the financials, Datacom chief executive Greg Davidson emphasized a strategic shift toward data sovereignty.

The results reflect broader pressures facing IT service providers, including rising costs and competitive intensity.

Datacom, which employs approximately 6,000 staff, is navigating a period of structural uncertainty that has weighed on earnings across the industry.

The company's financial performance underscores the difficulty of maintaining margin stability in a market where demand growth is not translating directly into bottom-line gains.
