A US paper-manufacturing giant is weighing a £6bn-plus takeover bid for Ireland (Other OTC: IRLD - news) 's Smurfit Kappa (LSE: SKG.L - news) as a wave of global deals fuelled by cheap debt continues to gather pace.
Sky News has learnt that International Paper Co is working with advisers at Deutsche Bank on a possible bid for Dublin-listed Smurfit, which specialises in the production of corrugated packaging.
Sources cautioned this weekend, however, that no formal approach had yet been made to Smurfit's board by International Paper, adding that the prospective bidder may yet decide not to pursue a deal.
One City source said that the American company, which has a market capitalisation of nearly $24bn (£16.4bn), had been looking at pitching an offer at about €36-a-share if it did press ahead with a proposal.
At that level, Smurfit's equity would be valued at more than £6bn, although with the company's debt and a conventional takeover premium included, a bid could be worth more than £8bn.
Smurfit's shares fell back after their initial surge last week to close at €28.91, although they are still up by more than 67% over the last 12 months.
If International Paper does lodge a bid for Smurfit Kappa, it would be the latest in a string of major takeover deals following the strongest start to a year for mergers and acquisitions for almost a decade.
In recent weeks, Heinz and Kraft Foods (Sao Paolo: KFGI34.SA - news) have agreed to merge in a $100bn (£68.3bn) deal, Royal Dutch Shell (Xetra: R6C1.DE - news) agreed to acquire BG Group (LSE: BG.L - news) in a takeover worth £47bn - the largest-ever transaction involving two London-listed companies - and the generic drug-maker Mylan (Berlin: 6MY.BE - news) offered to buy rival Perigo for $29bn (£19.8bn).
The timing of International Paper's interest is nevertheless likely to surprise analysts, some of whom played down the prospect of a bid for Smurfit earlier this week.
The Irish company's shares have soared in the last six months, while hopes of a broad economic recovery in the Eurozone, from where a significant proportion of its revenues derive, remain faint.
Smurfit operates in 32 countries, employing 42,000 people and boasting more than €8bn (£5.8bn) in revenue last year.
It makes packaging for clients in sectors as diverse as the retail flower market, tobacco manufacturers and high-value automotive goods.
There are already links between the Irish company and its purported predator: Paul Stecko, a non-executive director at Smurfit, spent 16 years with International Paper.
The company declined to comment on Saturday, while International Paper did not respond to a request for comment.
