Sterling目前83%的收入来自AI数据中心基础设施，高于一年前的60%，其数据看起来非常亮眼。但这一建设预计只持续几年且属一次性，按永续盈利估值很难。0.9倍的订单出货比是一个警示信号——积压订单消耗快于新增——不过一个季度并不值得惊慌；收购承包商可能降低这一风险。

Sterling 因财报上涨约6%，KLA Corporation 上涨7%。
Sterling's up about 6% on their earnings and KLA Corporation is up 7%.
Matt，我想在这里收尾，因为你提到了 Sterling Infrastructure，我觉得如果我们要谈这种“一锤子买卖”、做完一件事就结束的情况，Sterling 可能是我们这里谈到的三家公司之一。
And that's where I want to finish here Matt because you brought to the world sterling infrastructure which I think if we're going to talk about that one and done sort of we're going to do one thing and then it's over.
Sterling might be the one of the three that we're talking about here.
是的。我是说，如果你几年前看 Sterling 这家公司，它当时是修高速公路之类的。现在它大部分业务是建数据中心，而且集中度相当高。他们把这称为自己的电子基础设施业务板块。甚至一年前，当 AI 建设已经全面展开时，这块业务就占了他们收入的60%。
现在则达到83%。所以它现在是一家 AI 公司了，它不再是高速公路承包商了。
Yeah. I mean, Sterling, if you looked at the company a few years ago, it was like, you know, it built highways and things like that. Now, it builds data centers for the most part, and the concentration is pretty huge.
They called this their e infrastructure segment. And even a year ago when the AI build buildout was already in full swing, this made up 60% of their revenue. Now, it's at 83%. So, they are an AI company now.
They're not, you know, this is not a highway contractor anymore.
你提到过，这确实是一锤子买卖，出现了一些警示信号。数据中心你只需要建一次。这个季度的订单出货比（book-to-burn ratio）是让我特别关注的一点。它是0.9倍，意味着这个季度他们消耗掉的积压订单多于新增的积压订单。
0.9已经相当接近1，1.25也不至于引起警觉，所以我把这称为黄色警示信号，而不是红色警报。
Uh there are some yellow flags coming up to you mentioned that this could this is certainly a one and done. You only have to build your data center once. Um you know the book to burn ratio is one thing that really stood out to me this quarter.
It was.9x meaning that they worked through more of their backlog than they added to their backlog in this quarter. Now 0.9 is pretty close to 1 one and one quarter is not a cause for alarm which is why I call this a yellow flag and not a red flag.
我是说，这家公司的数据看起来非常出色，但即使是最乐观的 AI 多头也认为，这轮建设不会永远持续下去。正因如此，他们才称之为“建设期”。它会持续几年，然后我们就会拥有开发 AI 所需的数据中心基础设施。
And I mean the numbers from the business look fantastic, but even the most optimistic AI bulls, you know, believe that this buildout is not going to last forever. That's why they're calling it the buildout.
It's going to last for a few years. Uh and then we're going to have the data center infrastructure that that we need to to develop AI.
所以对 Sterling 来说，问题只在于这能持续多久，以及这部分未来收入值多少钱？因为我们给大多数股票估值，是基于它们将永久赚多少钱。而对于一些“一锤子买卖”式的 AI 标的，这真的很难做到。
Uh so Sterling, it's just a matter of, you know, how much is how long is it going to last and how much is that future revenue worth? because most stocks we value based on how much they're going to earn in perpetuity.
That's really tough to do with the some of the the one and done uh AI plays.
是的。如果我没记错，Sterling Infrastructure 应对这个问题的方式之一，就是开始收购其他承包商，这些承包商不只是浇筑混凝土、做场地准备工作的。我记得他们最近收购了一家电气承包商，也许还把它纳入自营。
也许是在巩固业务，让业务不再只有那种“一锤子买卖”的一面。
Yeah. And one of the ways, if I remember correctly, Sterling Infrastructure is trying to address this is they are starting to acquire other contractors that aren't just pouring concrete doing uh doing sort of the the site preparation work.
I think they recently bought an electrical contractor and maybe bringing that in-house as well. Maybe solidifying their business to move just not having that one and done sort of aspect of their business.
