It was another record quarter with some significant events. So why the negative reaction?
It was this segment of the earnings call indicating that it will be another three to five years before the knee of the earnings curve is hit as customer protocols are approved.

So it's really great to see always new customer always this cross-reference request for FDA master files and all that. This is mainly still for products -- industry products that are in the development, various stages of development. Everything from, I think, preclinical to registrational trial. I think the inflection point or perhaps an inflection point, of some of which you may have more than just one, will be even more of these products actually hit the market.

Sure. It's a great question. It's certainly a top of mind that. We try to analyze that through several different metrics. But, you know, nobody has the crystal ball, right, that can provide a lot of specificity. I think it's nice to say that the comments that we would make go like this. Nearly all the revenue today comes from not approved products, but from this clinical trial basket of customers. However, we have perhaps three to five additional approvals and or be late submissions that will happen in the next couple of quarters.
And we believe that the key sort of series of fresh inflection points are big step changes in the revenue are still out in the next three to five years. As you can imagine, having 10 to 20 or even 50 customers with approved therapies versus the situation that we have in the day. So we've got a wonderful growth opportunity ahead of us. And we're certainly not resting on our loyals, we continue to fill the pipeline with early stage companies. So the total universe of folks who are either currently using or intending to use our stuff in clinical trials is growing at a really rapid rate."
