Ausgold became the subject of a $776 million takeover offer from OceanaGold at an implied $1.36 a share, a deal L1 Capital backed as removing downside risk while preserving upside, even as activist investor Jeremy Raper publicly campaigned against it, arguing the bid undervalues the Katanning gold project relative to recent comparable sector mergers.

A profitable early entry rewarded by a takeover premium

L1 Capital said the proposed acquisition by OceanaGold provided a recent win for the fund, having accumulated Ausgold at around $0.50 a share before the $1.36-a-share implied takeover offer, though noting Ausgold is not particularly representative of the fund's core exposure, which focuses mainly on cash-flow-producing stocks, with only a smaller part of the book in what it considers the really compelling developer space. Holding a 9.1 percent stake, L1 Capital committed to voting its shares in favour of OceanaGold's $776 million takeover bid, contingent on no superior offer emerging, describing the arrangement as one that removes downside risk for Ausgold shareholders while still preserving upside from the premium on offer, and crediting Ausgold's management with doing a great job negotiating the deal and extracting value for the Katanning gold project.

An activist investor pushes back, arguing undervaluation

Jeremy Raper of Raper Capital publicly opposed the takeover, circulating an open letter to Ausgold's board arguing the bid undervalues the company, basing his case on valuation comparisons to other recent sector mergers, citing deals like Ramelius and Spartan, and contending the offer doesn't reflect the potential value of Katanning once developed, or of the surrounding infrastructure.

Raper published an open letter opposing the OceanaGold takeover bid for Ausgold, arguing the offer undervalues the company relative to valuation multiples seen in comparable recent gold-sector mergers, and that it fails to capture the future value of the Katanning project once in production, plus the surrounding infrastructure.

What fund managers say they are watching next is whether OceanaGold's offer proceeds as is or faces pressure to improve given Raper's public campaign, whether a superior competing offer emerges, which would void L1's voting commitment, and how Katanning's development potential and surrounding infrastructure value get reflected in any final deal terms.
