It's permanently closing its first unionized store in the United States.

We're on the next.

This is Bloomberg Tech.

Time now for Talking Tech, and first up, shares of China's ShareTronic data.

They plummeted 20%.

It's following US charges against Supermicro co-founder for allegedly smuggling Nvidia chips.

The company denies a relationship with Supermicro, but records show ShareTronic procured $92 million worth of Nvidia H100 and H200 processors, which have been banned from sale to and within China.

Meanwhile, Nvidia-backed Lumentum said demand from the biggest US tech companies for its optical components is accelerating and would be sold out through all of 2028, later this year.

The company is investing at least $100 million to expand its specialized factories in Japan, and the stock is up 1,500% over last year as investors bet on photonics as the essential plumbing for the next generation of AI data centers.

Meanwhile, Apple is shutting its first unionized retail store in the United States in June, citing declining conditions at the mall.

The company said in a statement that the employee can apply for open roles at Apple in accordance with the collective bargaining agreement.

The union representing 1,000 employees called the move union busting, saying Apple's claim about the agreement is, quote, simply false.

But let's dig into that.

Primo's Josh Idelson is here with more on their story.

So, is it that the mall isn't performing well?

Or is it that this was the one rare case of unionization?

How would evidence be weighed here?

I mean, several retailers, we know Crate & Barrel, Banana Republic have pulled back from that particular mall, but they're not all electronics sellers as well.

And so what is it that you've tended to see come forward in these years-long battles?
