Allegion raises 2026 guidance to 9.5%-10.5% revenue growth after $1.17B third-quarter sales

Allegion raised its full-year 2026 guidance after reporting third-quarter sales of $1,172.6 million and net income of $220.9 million. Basic earnings per share from continuing operations were $2.60. The security products maker now expects reported revenue growth of 9.5% to 10.5% and earnings per share of $8.35 to $8.40. Strong organic performance in its Americas non-residential security business drove the results. International remains the weak spot, where organic softness and margin pressure have not fully eased. Analysts assume 5.4% yearly revenue growth, reaching $5.1 billion by 2029.

Allegion stock lags market with 6.4% return, trades at 16.5× forward P/E amid slow growth concerns

Allegion plc, a provider of security products and solutions, has underperformed the S&P 500, posting a 6.4% return compared to the index's 16.6% gain since April 2026. The company currently trades at $153.33 per share. Allegion demonstrates strong operational efficiency with an average operating margin of 19.8% over the past five years. Its free cash flow margin has expanded by 6.1 percentage points during this period, reaching 15.6% in the trailing 12 months. However, the company's organic revenue growth has been underwhelming, averaging 4.1% year-on-year over the past two years. This suggests potential challenges with product development, pricing, or market strategy. The stock currently trades at 16.5× forward price-to-earnings ratio.

Allegion falls 10.7% over 52 weeks, underperforms Nasdaq's 20.9% gain
