Gold Fields (NYSE:GFI) closed at $35.44 on Monday, September 28, down 12.25% from $40.38 on Friday, after Australia's Northern Star Resources rejected its takeover proposal. The South Africa-based miner trades in New York through American depositary receipts, which are certificates that represent shares of a foreign company.

What Gold Fields Put on the Table

According to reports, Gold Fields made an unsolicited proposal to Northern Star on September 14. An unsolicited proposal is one the target did not ask for. It offered 0.3125 new Gold Fields shares plus A$7.25 in cash for each Northern Star share, which valued Northern Star at about A$38.7 billion, or roughly US$27 billion, and at about A$27 a share when the offer was made.

Because about three quarters of the consideration was paid in Gold Fields stock, the offer's value moved with the bidder's own share price. Reports said it had slipped to about A$25.19 a share by Friday's close, a premium of roughly 14% to Northern Star's previous close, compared with about 22% when the proposal was made.

Northern Star Says No

Northern Star's board unanimously rejected the proposal, according to reports, saying it undervalued the company's long-life Assets and came at an opportunistic time. Reports also said the board objected to conditions such as exclusivity, Due Diligence and regulatory approvals. Northern Star shares rose about 6.2% to A$23.47 on the Australian exchange, still below the implied offer value. Gold Fields said it remained open to constructive dialogue.

A Rare Fall for the Bidder

It is usually the target's shares that react to a takeover approach, so a double-digit fall for the would-be buyer stood out. A rejected bid leaves an acquirer without the growth the deal was meant to bring, and the outcome of any renewed approach is uncertain. The rejection also landed on a hard day for bullion, so the drop cannot be split neatly between the two.

December gold futures fell $152.80 to $4,168.40, the metal's worst session since June, and spot gold slid about 3.2% to a seven-week low near $4,148.69 according to market data. Bond yields were the main pressure point. The 10-year Treasury Yield rose to its highest level since 2007 and the 30-year yield to its highest since 2004, a move that raises borrowing costs and squeezes valuations across the market. The Fed's September 16 rate hike, which lifted its target range to 3.75% to 4.00%, is still fresh, and futures show better-than-even odds of another move in October.

What to Watch for Gold Fields

The central question is whether Gold Fields walks away, returns with improved terms or takes its case to Northern Star shareholders. Any statement from either company, and any filing on the matter, would be closely read after Monday's reaction. Northern Star's next move on the board's stance will matter as much.

Tuesday's JOLTS and consumer confidence readings, Wednesday's PCE Inflation figure, Thursday's ISM survey and Friday's jobs report are the main scheduled catalysts for yields this week. Firm data could push yields and the dollar higher and press on gold, while softer numbers could give miners room to recover.
