Reach, the publisher of the Daily Mirror and Daily Express, reported a 9% drop in annual adjusted operating profit to £96.5m after Facebook and other platforms referred less traffic to news sites.
The company's print revenue fell 2%, as a double-digit decline in advertising was largely offset by a strong circulation performance.
Digital revenue fell 15%, it said today, although it added that data-driven revenue - from registered users - continued to outperform the market and now represented 43% of its total.
Chief executive Jim Mullen said Reach now had clarity on two significant long-term uncertainties in pension funding and "historical legal issues", a reference to phone hacking cases, giving it a "clear path forward for the business".
Its Irish titles include the Irish Daily Mirror, the Irish Sunday Mirror and the Irish Daily Star as well as RSVP magazine and websites Dublin Live, Belfast Live, Cork Beo and Galway Beo websites.
Britain's Prince Harry earlier this month accepted substantial damages to settle his case against Reach's Mirror Group Newspapers.
