Catcher Technology Co. (CHERF) shares fell sharply early Wednesday, Sept. 13, on news Apple Inc. (AAPL) will use glass cases for its new phones, rendering Catcher's metal cases all but useless.

Stock in the Taiwan-listed metal case manufacturer tumbled the most since November after Apple, which is the company's biggest client, announced a new lineup of phones.

Catcher's bottom line could also take a hit as glass cases become the new norm for one of the most ubiquitous pieces of technology in the world, Concord Securities assistant VP Allan Lin told Bloomberg.

Apple represents more than half of Catcher's total sales. Catcher's chairman, Allen Hung, said last year that the company knew Apple would switch to glass cases, but expected the new phones to include some metal.

Catcher stock had risen a massive 71% in the first eight months of 2017, but has crumbled 13% in September. Shares traded down nearly 5% in Taiwan on Wednesday.
