Exhibit 99.1

NAPCO Security Technologies, Inc. Reports Fiscal Q4 and Full Year 2026 Results

AMITYVILLE, N.Y., August 24, 2026 /PRNewswire/ -- NAPCO Security Technologies, Inc. (NASDAQ: NSSC), one of the leading manufacturers and designers of high-tech electronic security equipment, wireless communication devices for intrusion and fire alarm systems and the related recurring service revenues as well as a provider of school safety solutions, today announced financial results for its fourth quarter and fiscal year 2026. Results are reported in accordance with U.S. generally accepted accounting principles (“GAAP”) and are also reported adjusting for certain items (“Non-GAAP”). A reconciliation between GAAP and Non-GAAP operating results is provided at the end of this press release.

Fourth Quarter 2026 Financial Results as Compared to Fourth Quarter 2025

● Net revenue increased 10.0% to a quarterly record $55.8 million, as compared to $50.7 million

● Recurring service revenue (“RSR”) increased 12.9% to $25.3 million, with over 90% gross margin, as compared to $22.4 million

● Equipment revenue increased 7.7% to $30.5 million, compared to $28.3 million

● Gross profit margin of 61.3%, which included a benefit of approximately 600 basis points from tariff refunds, vs 52.8% in prior fiscal year quarter

● Net Income increased 52.7% YoY to a quarterly record $17.8 million, as compared to $11.6 million

● Diluted Net Income per share increased 51.5% to $0.50, which is inclusive of a benefit of approximately $0.09 from net tariff refunds, as compared to $0.33

● Non-GAAP Adjusted EBITDA increased 44.3% to a quarterly record $20.6 million with an Adjusted EBITDA Margin of 36.8%

Full Year 2026 Financial Results as Compared to Full Year 2025

● Net revenue increased 11.4% to a record $202.3 million, as compared to $181.6 million

● RSR increased 13.0% to $97.5 million, with over 90% gross margin, as compared to $86.3 million

● RSR has a prospective annual run rate of approximately $103 million based on July 2026 recurring service revenues

● Equipment revenue increased 10.0% to $104.8 million, compared to $95.3 million

● Gross profit margin of 59.2%, which included a benefit of approximately 50 basis points from tariff refunds, vs 55.6% in prior fiscal year

● Net Income decreased (.9%) to $43.0 million, as compared to $43.4 million. Full year net income and net income per share were negatively affected by a $16 million litigation settlement charge taken in Q3 of fiscal 2026

● Diluted Net Income per share increased 0.8% YoY to $1.20, which is inclusive of a benefit of approximately $0.03 from net tariff refunds and negative impact of approximately $0.40 from net litigation settlement costs, as compared to $1.19

● Non-GAAP Net Income increased 32.0% to $57.3 million, as compared to $43.4 million

● Non-GAAP Diluted Net Income per share increased 34.5% YoY to $1.60, as compared to $1.19.

● Non-GAAP Adjusted EBITDA increased 27.9% YoY to a record $66.7 million, with an Adjusted EBITDA Margin of 33.0%

● The Board declared a quarterly dividend of $0.17 per share, payable on October 2, 2026 to shareholders of record on September 11, 2026.

Kevin Buchel, CEO and President, commented, “Our Fiscal Q4 performance completes a strong close to our fiscal year end and reflects continued positive financial results. We achieved record Q4 revenue and Adjusted EBITDA of $55.8 and $20.6 million, respectively, which was bolstered by our recurring service revenue with its continued year over year double digit growth. We saw a rebound in our equipment sales, which increased 10.0% for the year, driven by strong demand for our door-locking products as well as a 36% growth in sales of our intrusion products in Q4, which is primarily a result of increased sales of our StarLink fire communicators. Our RSR continues to deliver gross margins of over 90%, and represents approximately 45% of total revenue in Q4, and has a prospective run rate of approximately $103 million based on our July 2026 recurring service revenue. Our revenue growth and margin expansion in Q4 resulted in a 53% increase in net income, a 44% increase in Non-GAAP Adjusted EBITDA and our Adjusted EBITDA margin was 36.8% as compared to 28.1% in Q4 of Fiscal 2025.

As such we are pleased to continue our dividend program and will be increasing the quarterly dividend by 13.3% to $0.17 per share, which will be paid on October 2, 2026, to shareholders of record on September 11, 2026.”

Safe Harbor Statement

This press release contains forward-looking statements that are based on current expectations, estimates, forecasts and projections of future performance based on management's judgment, beliefs, current trends, and anticipated product performance. These forward-looking statements include, but are not limited to, statements relating to supply chain challenges and developments; the growth of recurring service revenues and annual run rate; the strength of our balance sheet; our expectations regarding future results; the introduction of new access control and locking products; the opportunities for school security products; the opportunities for fire alarm products; and our ability to execute our business strategies. Actual results, performance or achievements could differ materially from those anticipated in such forward-looking statements because of certain factors, including those risk factors set forth in the Company's filings with the Securities and Exchange Commission, such as our annual report on Form 10-K and quarterly reports on Form 10-Q. Other unknown or unpredictable factors or underlying assumptions subsequently proved to be incorrect could cause actual results to differ materially from those in the forward-looking statements. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, level of activity, performance, or achievements. You should not place undue reliance on these forward-looking statements. All information provided in this press release is as of today's date, unless otherwise stated, and the Company undertakes no duty to update such information, except as required under applicable law.

*Non-GAAP Financial Measures

Certain non-GAAP measures are included in this press release, including non-GAAP operating income, non-GAAP net income, non-GAAP net income per share (diluted), non-GAAP net income margin, Adjusted EBITDA, Adjusted EBITDA per share (diluted), Adjusted EBITDA per share margin, Free Cash Flow and Free Cash Flow margin. We define non-GAAP net income as GAAP net income plus litigation settlement costs. We define Adjusted EBITDA as GAAP net income plus income tax expense, net interest income (expense), stock-based compensation, non-recurring legal expenses, litigation settlement costs, and depreciation and amortization expenses. Non-GAAP net income margin is non-GAAP net income divided by revenue. Adjusted EBITDA margin is Adjusted EBITDA divided by revenue. We define Free Cash Flow (FCF) as net cash provided by operating activities less capital expenditures. FCF margin is the FCF divided by revenue. These non-GAAP measures are provided to enhance the user's overall understanding of our financial performance. By excluding these charges our non-GAAP results provide information to management and investors that is useful in assessing NAPCO's core operating performance and in comparing our results of operations on a consistent basis from period to period. Our use of non-GAAP financial measures has certain limitations in that such non-GAAP financial measures may not be directly comparable to those reported by other companies. For example, the terms used in this press release, such as Adjusted EBITDA, do not have a standardized meaning. Other companies may use the same or similarly named measures, but exclude different items, which may not provide investors with a comparable view of our performance in relation to other companies. The presentation of this information is not meant to be a substitute for the corresponding financial measures prepared in accordance with generally accepted accounting principles. Investors are encouraged to review the reconciliation of GAAP to non-GAAP financial measures set forth above.
