Everbridge Announces Third Quarter 2023 Financial Results

Company Delivers Solid Third Quarter Revenue and Improved Profitability

BURLINGTON, Mass – November 9, 2023 – Everbridge, Inc. (Nasdaq: EVBG), the global leader in critical event management (CEM) and national public warning solutions, today announced its financial results for the third quarter ended September 30, 2023. Revenue for the third quarter was up 3% year-over-year to $114.2 million, and GAAP net income was $1.7 million, compared to a net loss of $(22.1) million for the third quarter of 2022.

“We delivered solid third quarter results as we continue to improve our go-to-market execution and overall operating efficiency,” said David Wagner, President and CEO of Everbridge. “We saw healthy year-over-year improvements, including our strongest recurring bookings quarter of the year, and efficiency improvements across the business allowing us to increase adjusted EBITDA by $8.5 million in the third quarter compared to last year.”

Patrick Brickley, Executive Vice President and Chief Financial Officer of Everbridge, added, “Our improving profitability is supported by continued strength in our subscription revenue growth despite challenges associated with one-time services and perpetual software license revenue, which were down year-over-year. In the fourth quarter, we expect to further improve our earnings while, at the same time, our one-time revenues are now expected to decrease by about $6 million compared to the fourth quarter of 2022. Our 2023 full-year guidance represents an approximately 100% year-over-year improvement in adjusted EBITDA.”

Wagner continued, “As we look forward, we believe consistent growth in our subscription revenues, strong expense management, and our streamlined product portfolio have us positioned for meaningful growth in profitability in 2024, which will keep us on track towards our goal of reaching the ‘Rule of 40’ by 2027.”

Key Performance Metric

Annualized Recurring Revenue (ARR) is defined as the expected recurring revenue in the next twelve months from active customer contracts, assuming no increases or reductions in the subscriptions from that cohort of customers. Investors should not place undue reliance on ARR as an indicator of future or expected results. Our presentation of this metric may differ from similarly titled metrics presented by other companies and therefore comparability may be limited.

Non-GAAP Financial Measures

This press release contains the following non-GAAP financial measures: non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating income/(loss), non-GAAP net income/(loss), non-GAAP net income/(loss) per share, EBITDA, adjusted EBITDA, free cash flow, adjusted free cash flow and adjusted EBITDA margin.

Non-GAAP operating income/(loss) excludes amortization of acquired intangible assets, stock-based compensation, costs related to the 2022 Strategic Realignment, Anvil legal dispute accrual and change in fair value of contingent consideration. Non-GAAP net income/(loss) excludes amortization of acquired intangible assets, stock-based compensation, costs related to the 2022 Strategic Realignment, Anvil legal dispute accrual, change in fair value of contingent consideration, accretion of interest on convertible senior notes, gain (loss) on extinguishment of debt, capped call modification and change in fair value and the tax impact of such adjustments. EBITDA represents net income/(loss) before interest income and interest expense, income tax expense and benefit and depreciation and amortization expense. Adjusted EBITDA represents EBITDA as further adjusted for stock-based compensation expense, costs related to the 2022 Strategic Realignment, Anvil legal dispute accrual, change in fair value of contingent consideration and gain (loss) on extinguishment of debt, capped call modification and change in fair value. Free cash flow represents cash provided by (used in) operating activities minus cash used for capital expenditures and capitalized software development costs. Adjusted free cash flow represents free cash flow as further adjusted for cash payments for the 2022 Strategic Realignment.

We believe that these non-GAAP measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to Everbridge's financial condition and results of operations. We use these non-GAAP measures for financial, operational and budgetary decision-making purposes, to understand and evaluate our core operating performance and trends, and to generate future operating plans. We believe that these non-GAAP financial measures provide useful information regarding past financial performance and future prospects, and permit us to more thoroughly analyze key financial metrics used to make operational decisions. We believe that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends and in comparing our financial measures with other software companies, many of which present similar non-GAAP financial measures to investors.

We do not consider these non-GAAP measures in isolation or as an alternative to financial measures determined in accordance with GAAP. The principal limitation of these non-GAAP financial measures is that they exclude significant expenses and income that are required by GAAP to be recorded in the Company's financial statements. In addition, they are subject to inherent limitations as they reflect the exercise of judgment by management about which expenses and income are excluded or included in determining these non-GAAP financial measures. In order to compensate for these limitations, management presents non-GAAP financial measures in connection with GAAP results. We urge investors to review the reconciliation of our non-GAAP financial measures to the comparable GAAP financial measures, which are included in this press release, and not to rely on any single financial measure to evaluate our business.
