David D. Petratis
Chairman, President and Chief Executive Officer at Allegion
Thanks, Tom. Good morning and thank you for joining us today. Before we go into our third quarter results, I'd like to take a minute to acknowledge and congratulate my fellow Allegion team members for their ongoing dedication to the environment, society, and governance. I'm humbled and honored to share that just last week Allegion was recognized for ESG leadership through two different awards, the Robert W. Campbell Award and the Jackson Lewis Diversity, Equity & Inclusion Champion Award.
The Campbell Award is an annual recognition by the National Safety Council, America's leading nonprofit safety advocate. It is the premier award for excellence in integrating environmental, health, and safety management into business operating systems. Winners have strong processes and show measurable achievements over a five-year period. In the EH&S performance that leads to productivity and profitability, and are expected to demonstrate a long-term track record of not just EH&S compliance, but also critical improvements.
The prestigious award is also known for its rigorous application process with a systematic review and audit attached to it. Submissions are reviewed by management, labor, academic, and government experts from around the world, followed by a meticulous audit format at three or more of a company's global sites. With this in mind, Campbell Award winners are an elite group of organizations. Past winners include Boeing, Cummins, Dow Chemical, DuPont, Honeywell Aerospace and Johnson & Johnson. Allegion is proud to have our name added to this best-in-class list.
We are also excited to have been named the Jackson Lewis Diversity, Equity & Inclusion Champion Award by the Indiana Chamber of Commerce. This is a statewide honor that recognizes an organization making significant strides in the workplace. The judge noted that Allegion was chosen as its first ever winner of this award because of our company's proactive and intentional diversity, equity, and inclusion efforts around the globe.
We have strong momentum on our diversity efforts, and we know there's more work to be done. We're not asking the people of Allegion to agree on everything, but we need to be a place where racism and bias are rejected, where inclusion is a way of life, and where all employees feel they belong and contribute to our business success. Importantly, I've shared before that Allegion's ESG commitments are vital to how our company achieves results and the way we do business. ESG excellence will give us better long-term outcomes across the board, better employee safety, better employee engagement, better productivity, better creativity, better innovation, and stronger financial performance. We see this first-hand and external data points to it as well.
Please go to slide 5. During the quarter, we experienced continued strength in demand, particularly in the Americas' non-residential market. This trend began in Q2 and accelerated through Q3. Leading indicators like ABI and Dodge new construction indices remain positive. Increased demand is for both discretionary projects and new construction and is across all verticals and product categories. The recovery has been faster than we originally anticipated and is expected to continue in the foreseeable future. Residential end-market demand is also favorable across both retail point-of-sale and new home construction.
The strengthened demand continues to constrain the global supply chain's ability to fully meet demand requirements. Similar to last quarter, this was especially prevalent in electronic components in Q3. As I'm sure you're aware, this is a global issue and not isolated to Allegion or to any single industry. We have redirected resources and are taking actions such as reconfiguring and redesigning products as well as developing alternative sources of supply to help alleviate the pressures we are experiencing in procuring electronic components.
Additionally, material and freight input costs continued to accelerate during Q3. We now anticipate material and freight inflation to be, approximately, $60 million higher compared to last year. In addition to the supply chain pressures we're seeing for electronics, there are also widespread industry shortages of labor and other components. Once again, these issues are not Allegion-specific, and we expect the global constraints driving these shortages to continue beyond 2021. These challenges led to margin deterioration in the quarter. We will leverage the strength of our supply chain management capabilities, as well as priced to help mitigate these impacts going forward.
During the quarter, the continued robust demand coupled with the supply chain pressures resulted in record backlogs; approximately, four times normal levels. We estimate that widespread shortages have delayed approximately $80 million to $100 million of 2021 revenue. We believe this impact is evenly distributed across the third and fourth quarter. We do not believe this is lost revenue but expect it will be recovered as supply chain constraints ease.
Now let's turn to the third quarter performance. For more details, please go to slide 6. Revenue for the third quarter was $717 million, a decrease of 1.6% on both a reported and organic basis. The organic revenue decrease was driven by lower volume in the Americas region related to the aforementioned electronics, components, and labor shortages. Currency tailwind and acquisitions offset the impact of divestitures. Patrick will share more details on the regions in a moment. Adjusted operating margins decreased by 330 basis points in the third quarter. Higher input costs, productivity challenges, and volume deleverage drove the majority of the decrease. Incremental investments important to our future growth caused 90 basis points of the decline. Adjusted earnings per share of $1.56 decreased $0.11, or 6.6%, versus the prior year. The decrease was driven by reduced operating income, offset by a favorable tax rate and share count. Year-to-date available cash flow came in at $327.7 million, an increase of $71.6 million, or 28% versus the prior year. The increased cash flow was driven by higher year-to-date net earnings along with improvement in net working capital and reduced capital expenditures.
Patrick will now take you through the financial results and I'll be back later to discuss our 2021 outlook and wrap up.
