Thanks, Louis, and good morning, everyone. As you just heard, Regal Rexnord had very strong results in Q3, and I'd also like to send my congrats to our global team for executing so well in the face of severe inflation and global supply chain disruptions.
Now let's discuss our results by segment, and then I'll walk through our latest guidance, which incorporates us owning the Rexnord PMC business as of the merger close on October 4 and assumes we'll close Arrowhead by the end of this year. We'll start with our legacy Power Transmission Solutions, or PTS, segment. To be clear, these results only reflect legacy PTS. Beginning in the fourth quarter, legacy PTS plus the Rexnord PMC business forms our new Motion Control Solutions segment or MCS.
Organic sales for PTS in the third quarter were up 23.7% from the prior year on broad-based strength across every market served, with particular strength in alternative energy, North America general industrial and the conveying business. In addition, the business had meaningful tailwinds from share gains, including from our industrial powertrain solutions offering. Pruning actions were approximately 290 basis points of top line headwind in the quarter.
Operating margin in the quarter for PTS was 18.8%, up 600 basis points compared to the prior year. Very strong performance aided by volume, price and permanent restructuring actions.
Orders in PTS for the quarter were up 40%, and orders for the new MCS segment are tracking up over 30% in October, both on a daily basis.
Turning to Climate Solutions. Organic sales in the third quarter were up 14.2% from the prior year. The increase was driven by broad-based strength in all markets, with particular strength in North America residential HVAC markets, in EMEA and in North America general industrial markets. The business also achieved nice market share gains, mostly in the North America HVAC distribution business in Europe and in Asia. Pruning actions were approximately 180 basis points of top line headwind in the quarter.
The adjusted operating margin in the quarter for climate was 19.4%, up 230 basis points versus the prior year period. A number of factors contributed to this strong performance, including the drivers I mentioned a minute ago, along with a continued shift to more energy-efficient variable speed motors. Permanent cost reductions and achieving modestly positive price cost also benefited climate's margin in the quarter.
Orders in climate for the third quarter were up nearly 20% on a daily basis and are tracking at nearly the same pace in October, both on fairly broad-based strength, but with particularly healthy momentum in the EMEA and commercial refrigeration verticals. Based on our current backlog and what we're hearing from our HVAC OEM customers, our assessment is that end-user demand remains healthy and that significant restock activity is still ahead of us and likely to occur in the first half of 2022.
Turning to Commercial Systems. Organic sales in the third quarter were up 20.9% from the prior year. Growth in the quarter reflects strength in North America general industrial markets and strong performance in large commercial HVAC products, especially in China. We're also confident our commercial business is achieving some nice share gains, especially in the North America general industrial market. 80/20-related pruning was a 220 basis point sales headwind in the quarter.
The adjusted operating margin in the quarter for Commercial Systems was 11.5%, down slightly compared to the prior year. Continued headwinds from inflation, along with supply chain disruptions, contributed to the year-over-year results. Furthermore, while overall price cost was slightly favorable in the quarter, this had a dilutive impact on margins.
Orders in commercial for the third quarter were up 35% on a daily basis and are tracking up almost 20% in October.
In Industrial Systems, organic sales in the third quarter were up 3.6% versus the prior year. Principal drivers included strength in China and improving momentum in the North America nonresidential construction and general industrial end markets, partially offset by lapping prior year large project activity in the data center market. Pruning actions during the quarter were approximately 210 basis points of top line headwind.
The adjusted operating margin in the quarter for industrial was 3.4%. Keep in mind that this segment's margins are highly sensitive to small dollar value shifts in operating performance.
Orders in industrial for the quarter were up approximately 14% on a daily basis. Order rates in October are up at a low teens rate when excluding some large prior period project orders in the data center market.
On the following slide, we highlight some key financial metrics for your review. A couple of notable highlights. First, on the right side of this page, we further delevered the balance sheet and ended the quarter with net debt to adjusted EBITDA of 0.5x. However, after factoring the impacts of closing the merger with Rexnord PMC, along with the Arrowhead transaction announced today, we anticipate close -- which we anticipate closing during the fourth quarter, our net debt to adjusted EBITDA is expected to be roughly 1.1x as we exit this year, affording us lots of optionality.
Second, our free cash flow of $108 million or 133% of adjusted net income is a strong result, and we continue to expect cash conversion above 100% for the year.
Moving to the outlook. Lots of moving pieces here, but we've attempted to provide as much clarity as possible. We are providing guidance for the fourth quarter of 2021 and initial annual adjusted EPS guidance for 2022. Our outlook incorporates 5 factors: one, our latest expectations for performance at our legacy Regal business; two, expected results for the Rexnord PMC business beginning in the fourth quarter; three, PMC merger-related impacts, including additional shares, interest, depreciation and amortization and our expected post-merger tax rate; four, impacts in 2022 related to the Arrowhead transaction that we announced today; and five, a new definition of adjusted earnings per share, which, beginning with the fourth quarter of 2021, will be calculated, adding back all amortization and stock-based compensation expense, both on an after-tax basis, in addition to the adjustments we have made historically.
We believe our new definition of adjusted EPS is consistent with what investors sometimes refer to as cash EPS, and going forward, we will be providing guidance and earnings commentary using this new definition of adjusted EPS. It is also what we would expect to define the non-GAAP consensus value for our EPS beginning with the fourth quarter.
Please also note that going forward, our discussions of operational performance will focus on adjusted EBITDA instead of adjusted operating income, and our definition of adjusted EBITDA will now include adding back stock-based compensation expense. To help investors update their models for our new approach, we are providing historic details by quarter on depreciation, amortization and stock-based compensation for total Regal Rexnord and by segment in the appendix to our third quarter press release and slide deck.
Now turning to the outlooks. For the fourth quarter of 2021, we expect total Regal Rexnord sales to grow at a mid-teens rate versus prior year, and we expect to deliver adjusted earnings per share in a range of $1.97 to $2.27. For reference, the outlook we're providing for the fourth quarter is consistent with our prior outlook for legacy Regal, along with the prior outlook for legacy PMC provided by Rexnord. To this, we layer on PMC merger-related impacts, including higher shares, interest, depreciation and amortization and a modestly higher tax rate, and we now present the outlook according to our updated definition of adjusted earnings per share.
For 2022, we now expect revenue of approximately $5.1 billion, adjusted EBITDA of approximately $1.1 billion and adjusted EPS in a range of $9.95 to $10.35. Our outlook for 2022 is consistent with what we said previously regarding our expectations for revenue and adjusted EBITDA, which we expected to be approximately $5 billion and at least $1 billion, respectively, but now adds the impact of Arrowhead.
Note that while we expect Arrowhead to close sometime during the fourth quarter of this year, from a guidance perspective, we do not add it to our P&L until January 1, 2022. So if we end up closing earlier than that, as we expect, there could be a modest upward impact to our 4Q outlook.
Lastly, I'd like to reiterate that after giving effect to the merger with PMC and the acquisition of Arrowhead, we anticipate having a very healthy balance sheet with net debt to adjusted EBITDA anticipated approximately 1.1x at the end of 2021.
Shifting focus to the table on the right-hand side of this slide, you will see that we provided a summary of our key guidance points for 4Q and for 2022, including the incremental impacts related to Arrowhead. At the bottom of this table, we also provide a number of modeling details. Given all the merger-related fluctuations to income statement items below EBITDA, we wanted to help investors align around how adjusted EBITDA bridges to an adjusted EPS value under our new definition for that metric.
And with that, I will now turn the call back over to Louis to discuss Arrowhead.
