Thank you, Dave. The reviews that you continue to conduct with me and the team always leave us in a better place, and our business is actually in a much better place because of your involvement. So all of you on today's call, thank you for being here. I'm eager for you to hear more about our 2021 third quarter performance, our outlook on the market and an update on our portfolio. There are 6 key messages I want to convey today.
First, as Dave mentioned, demand for Vertiv products and services remain strong. During our last earnings call, we reported second quarter sales were up more than 25% and orders were up 24% compared to the second quarter of last year. I'm pleased to report that sales and orders are up again in Q3. Sales were up 6%, which is very much in line with the guidance we provided in our last update and orders were up 17%. In addition, our Q3 backlog rose to $2.4 billion, the highest it's ever been.
Second, profitability is up. This quarter, our adjusted operating profit was $131 million, up $64 million from last year's third quarter. This resulted in adjusted operating margin expansion of 490 basis points.
Third, year-to-date free cash flow is greater today than it was this time last year. Free cash flow for Q3 was $44 million and year-to-date is $128 million. For a year -- from a year-to-date perspective, this represents an improvement of over $140 million versus the first 3 quarters of 2020.
Fourth, as Dave mentioned, we are dealing, like others, with supply chain and inflationary issues. We encountered supply chain challenges in Q3 and experienced commodity and freight inflation. We made spot buys so that we can meet our delivery commitments we've made to our customers, and we have implemented strategies to recapture those costs. Pricing always lagged cost by a few quarters, and that's exactly what we're seeing now. However, we believe, as we've mentioned before, pricing will be a tailwind in 2022.
Fifth. We expect to close the E+I acquisition by November 1, which is a month earlier than previously communicated. In addition, we've signed an agreement to sell our heavy industrial UPS business, and we expect to close that transaction by the end of Q4.
And the final key message is, we are confirming our latest guidance for the Vertiv base and slightly increasing our guidance for the impact of the M&A transaction.
Turning to Slide 4. This is the chart we use to illustrate what we're seeing in each of our world regions in each of our end markets. In the cloud and hyperscale colocation markets, they continue to remain strong as evidenced by the green buttons. The demand for digital continues to fuel the industry and is driving a strong and growing need for Vertiv products and services.
In our enterprise and small to medium business market, we continue to see signs of progress. Enough progress is made in Americas to upgrade this segment from yellow to green. We continue to experience an increase in the pipeline and orders with Americas leading the way. The communication networks had a few moments. We saw 5G deployments in earlier parts of the year being very robust and began to see that slow or a digestion over the last quarter or so. We've experienced Europe beginning to deploy 5G, and we see consistent deployment in Americas. In the commercial and industrial markets, things remain consistent. While this is a smaller size of our business, the variety of products and services we sell here continue to expand.
Moving to Slide 5. As referenced in my opening slide, our order rates continue to be robust. Our Q3 order rates were up 17% over Q3 of 2020 and on a year-to-date basis are up 21% versus the same time period last time with cloud and colocation segment leading our way. Vertiv's executive team remains closely connected to the accounts, and we're seeing the strong demand continue. Because of the deliberate connections we are making, we are gaining further visibility into customer demand, leading to advanced orders and insight to their future pipelines that we haven't seen in the past, which is a tremendous help in our demand planning as we go forward. This and other actions we are taking have led to a record backlog, as I mentioned earlier, of $2.4 billion, which is 34% higher than our backlog was at the end of 2020.
As you heard from Dave in his opening comments, supply chain continues to pose challenges for us and many, many others in the industry. Each of the regions are experiencing it, but it is most acute in Americas, where material availability is most difficult and commodity prices have risen beyond expectations. Where necessary, we'll continue to use spot buys so that we can take care of our customers. From a pricing standpoint, we are in line with our prior guidance we provided for Q4. We'll continue with pricing actions throughout 2022.
Moving to Slide 6. When we spoke last, we expected to close the E+I deal by December 1, but I'm very pleased that we will be able to close this deal a month earlier due to the diligence of the combined Vertiv and E+I teams and with help from our transaction partners. We had successfully -- we had a successful debt raise a few weeks back, and all antitrust hurdles have been cleared. The market reaction has been overwhelmingly positive. Gary, Phil, our Regional President, I have been on the phone with hundreds of customers and the receptivity to the deal is exactly what we wanted, very optimistic and very excited. Integration planning has started right after the deal was signed, and I look forward to entering into the execution mode in a few days. While E+I orders remain very strong, they are facing site readiness and supply issues on electric components, no different than others in the industry.
Now let's turn to divestitures of the heavy-duty industrial UPS business. We have signed an agreement to sell this business to a financial sponsor called InnovaFonds. InnovaFonds will retain the existing management team, which makes for a very easy transition and provides for great customer continuity. We expect this transaction, as mentioned early, to close by the end of Q4.
With that, I'll turn it over to David to take a closer look at the Q3 numbers and we'll come back with some final comments at the end. David?
