forward-looking statements financial

"This presentation contains "forward-looking statements" within the meaning of Section 27A..."

Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.

safe harbor regulatory

"These statements are made under the “safe harbor” provisions of the U.S. Private Securities Litigation Reform Act of 1995."

Safe harbor is a rule that protects companies or individuals from legal trouble if they follow certain guidelines or procedures. It’s like having a safety net that allows them to act without fear of punishment, as long as they stick to the rules. This helps encourage honest behavior and clear standards in financial and legal activities.

outsourced semiconductor packaging, testing and electronic manufacturing services financial

"demand for the outsourced semiconductor packaging, testing and electronic manufacturing services we offer..."

Private Securities Litigation Reform Act of 1995 regulatory

"under the “safe harbor” provisions of the U.S. Private Securities Litigation Reform Act of 1995."

Annual Report on Form 20-F regulatory

"it has filed its annual report on Form 20-F for the year ended December 31, 2025..."

An annual report on Form 20-F is a standardized filing that foreign companies submit to the U.S. securities regulator to disclose their financial results, business operations, risks, and management’s discussion of performance. It matters to investors because it provides a complete, audited snapshot—like a company’s financial report card and shareholder letter combined—used to assess transparency, compare companies, and judge whether the stock’s price matches underlying business strengths and risks.
