Intel gave a strong sales forecast for the current period, signaling that the struggling chipmaker is finally beginning to benefit from the giant build-out of artificial intelligence infrastructure. Revenue will be $13.8 billion to $14.8 billion in the quarter ending in June, the company said Thursday in a statement. Analysts, on average, estimated $13 billion, according to data compiled by Bloomberg. Earnings, excluding some items, will be about 20 cents a share, compared with a Wall Street prediction of 9 cents. The upbeat outlook suggests that Chief Executive Officer Lip-Bu Tan is making progress on a challenging comeback plan. After lining up major investments in Intel last year — helping to strengthen the company’s balance sheet — Thursday’s results suggest he’s now delivering on a promise to improve its operations. Intel shares rose 14% in extended trading. The stock had gained 81% this year before the results were released, closing at $66.78.
