0718 GMT - Shell's outlook is improved by high energy prices and the ARC Resources acquisition, Baader Helvea's Frederic Lorec writes. The British energy major agreed to buy Canadian energy producer ARC for about $13.6 billion in April. Baader increases its 2026 earnings per share forecast to $5.76 from $4.45, and its 2027 estimate to $5.57 from $4.48. The upwards revision is largely driven by higher oil price assumptions and additional barrels from ARC. Shares rise 0.6% to 3,511 pence.
