NEWS RELEASE

BHP successfully completes US$5.2 billion off-market buy-back of BHP Group Limited shares and announces US$1.02 per share special dividend

BHP has successfully completed its off-market tender buy-back (Off-Market Buy-Back) of BHP Group Limited (formerly BHP Billiton Limited) shares. The final transaction size of A$7.3 billion (US$5.2 billion)⁽¹⁾ has enabled BHP Group Limited to buy back approximately 265.8 million BHP Group Limited shares, which represents 8.3 per cent of the issued share capital of BHP Group Limited and 5.0 per cent of the total issued capital of BHP Group Limited and BHP Group Plc.

The final price for the Off-Market Buy-Back has been set at A$27.64 per share (Buy-Back Price). This is a discount of 14 per cent to the Market Price⁽²⁾ of A$32.1387 per share.

In addition, the Board of BHP has determined to pay a special dividend (Special Dividend) of US$1.02 per share, which will be paid to all BHP shareholders with an entitled registered holding as of Friday 11 January 2019. The Special Dividend represents the residual US$5.2 billion of net proceeds from the sale of its Onshore US assets not returned via the Off-Market Buy-Back, based on the reduced number of shares on issue of approximately 5,058 million following completion of the Off-Market Buy-Back.

BHP Chief Financial Officer, Peter Beaven, said: “We are pleased to have completed the Off-Market Buy-Back which, together with the Special Dividend, will deliver on our commitment to return the net proceeds from the sale of our Onshore US assets to our shareholders. Completion of this program will bring total cash returned to shareholders to US$21 billion over the last two years.”

Off-Market Buy-Back completion

Due to the strong demand for the Off-Market Buy-Back, a scale back of tenders was required.

The scale back was structured to minimise eligible registered shareholders with small holdings being disadvantaged. Subject to exclusions due to any minimum price conditions, shareholders who tendered their shares at a 14 per cent discount or as a final price tender will have a priority allocation of 165 shares bought back before the scale back is applied. In addition, successful shareholders who tendered all of their shares at a 14 per cent tender discount or as a final price tender, and who would be left with 65 shares or fewer as a result of the priority allocation and scale back, will have their tender accepted in full. As a result of the 58.7 per cent scale back, successful shareholders will have 41.3 per cent of their shares tendered in excess of the priority allocation bought back.

For shareholders who have successfully tendered their shares, A$27.26 per share of the Buy-Back Price is treated for Australian tax purposes as a fully franked dividend. For Australian capital gains tax purposes, the capital proceeds are A$4.92 per share, being the A$0.38 per share capital component plus A$4.54 per share, which is the excess of the Tax Value (as defined in the Buy-Back Booklet) over the Buy-Back Price.

Payments via direct credit and dispatch of cheques for shares bought back are expected to be completed by Monday 24 December 2018. Shares that have been tendered into the Off-Market Buy-Back but not bought back are expected to be released to shareholders during Monday 17 December 2018.
