EXPLANATORY NOTE

As previously announced, on February 4, 2024, Everbridge, Inc. (the “Company,” “Everbridge,” “we,” “us,” or “our”) entered into an Agreement and Plan of Merger (the “Original Merger Agreement”) with Project Emerson Parent, LLC (“Parent”) and Project Emerson Merger Sub, Inc. (“Merger Sub”), as amended and restated on February 29, 2024 (the “A&R Merger Agreement” and together with the Original Merger Agreement, the “Merger Agreement”). The Merger Agreement provides that, subject to the terms and conditions set forth in the Merger Agreement, Merger Sub will merge with and into Everbridge (the “Merger”), with Everbridge continuing as the surviving corporation of the Merger and a wholly owned subsidiary of Parent. Parent and Merger Sub are affiliates of Thoma Bravo Discover Fund IV, L.P. (the “Thoma Bravo Fund”), an investment fund managed by Thoma Bravo, L.P. On April 25, 2024, the Company held a special meeting of its stockholders (the “Special Meeting”) at which the Company’s stockholders approved, among other things, the Merger Agreement. The proposed Merger is targeted to close in the second quarter of 2024 and, in light of the proposed Merger, the Company currently does not anticipate holding an annual meeting of stockholders in 2024.

This Amendment No. 1 to Form 10-K/A (the “Amendment”) amends the Annual Report on Form 10-K (the “Original 10-K”, and as amended by this Form 10-K/A, the “Form 10-K”) of the Company for the year ended December 31, 2023, which was originally filed with the Securities and Exchange Commission (the “SEC”) on February 27, 2024. This Amendment is being filed to amend Part III to include information required by Items 10 through 14.

The information required by Items 10 through 14 of Part III was previously omitted from the Original 10-K in reliance on General Instruction G(3) to Form 10-K, which permits the information in the above-referenced items to be incorporated in the Form 10-K by reference from our definitive proxy statement if such statement is filed no later than 120 days after our fiscal year end. We are filing this Amendment to include Part III information in our Form 10-K because a definitive proxy statement containing this information will not be filed by us within 120 days after the end of the fiscal year covered by the Form 10-K. The reference on the cover of the Original 10-K to the incorporation by reference to portions of a definitive proxy statement or amendment to our Form 10-K into Part III of the Original 10-K is hereby deleted.

In accordance with Rule 12b-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), Part III, Items 10 through 14 of the Original 10-K are hereby amended and restated in their entirety. Pursuant to Rule 12b-15 under the Exchange Act, this Amendment also contains new certifications pursuant to Section 302 of the Sarbanes-Oxley Act of 2002 from our principal executive officer and principal financial officer. As no financial statements are included in this Amendment and this Amendment does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4 and 5 of the certifications have been omitted. Additionally, as no financial statements have been included in this Amendment, certifications pursuant to Section 906 of the Sarbanes-Oxley Act of 2002 have been omitted.

Except as specifically set forth herein, this Amendment does not amend or otherwise update any other information in the Original 10-K. Accordingly, this Amendment should be read in conjunction with the Original 10-K and with our filings with the SEC subsequent to the Original 10-K.

The Audit Committee is currently composed of four directors: Ms. Dean and, Messrs. D’Amore, Ghai and Henshall.

Our Board has determined that each of Ms. Dean, Mr. D’Amore, Mr. Ghai and Mr. Henshall are independent directors under The Nasdaq Stock Market, LLC (“Nasdaq”) listing rules and under Rule 10A-3 under the Exchange Act.

•

Non-GAAP net income was $64.7 million compared to $31.9 million for 2022. Non-GAAP diluted net income per share was $1.48, based on 43.8 million diluted weighted average common shares outstanding, compared to $0.70 for 2022, based on 45.9 million diluted weighted average common shares outstanding.

Non-GAAP Financial Measures

This Amendment contains the following non-GAAP financial measures: non-GAAP operating income, non-GAAP net income, non-GAAP net income per share, adjusted EBITDA and adjusted free cash flow.

Non-GAAP Financial Measures. Non-GAAP operating income, non-GAAP net income and non-GAAP net income per share exclude all or a combination of the following (as reflected in the following reconciliation tables): 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 on extinguishment of debt, capped call modification and change in fair value and the tax impact of such adjustments. The tax impact of such adjustments was determined by recalculating current and deferred taxes utilizing non-GAAP pre-tax income for the year and analyzing changes in valuation allowance post purchase accounting. The presentation of the non-GAAP financial measures is not intended to be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP. We use these non-GAAP financial measures for financial and operational decision-making purposes and as a means to evaluate period-to-period comparisons. We believe that these non-GAAP financial measures provide useful information about our operating results, enhance the overall understanding of past financial performance and future prospects and allow for greater transparency with respect to metrics used by our management in its financial and operational decision making. While our non-GAAP financial measures are an important tool for financial and operational decision making and for evaluating our own operating results over different periods of time, you should consider our non-GAAP financial measures alongside our GAAP financial results.

We believe that excluding the impact of amortization of acquired intangibles allows for more meaningful comparisons between operating results from period to period as the intangibles are valued at the time of acquisition and are amortized over a period of several years after the acquisition. We exclude stock-based compensation expense which can vary based on plan design, share price, share price volatility, and the expected lives of equity instruments granted. We believe that providing non-GAAP financial measures that exclude stock-based compensation expense allow for more meaningful comparisons between our operating results from period to period because stock-based compensation expense does not represent a cash expenditure. We believe that excluding costs related to the 2022 Strategic Realignment allows for more meaningful comparisons between operating results from period to period as this is a discrete event based on a unique set of business objectives and is incremental to the core activities that arise in the ordinary course of our business. We believe that excluding the Anvil legal dispute accrual, which reflects an estimated potential liability in connection with a lawsuit filed in April 2022 by certain former shareholders of The Anvil Group (International) Limited, Anvil Worldwide Limited and The Anvil Group Limited (collectively, “Anvil”), allows for more meaningful comparisons between operating results from period to period as the litigation expense being excluded is not considered a normal, recurring expense, does not have a direct correlation to the operations of our business and is outside of the ordinary course of business due to the lack of frequency of similar cases that have been brought against us to date, the complexity of the case and the nature of the remedies sought. We believe that excluding the change in fair value of contingent consideration allows for more meaningful comparisons between operating results from period to period as it is non-operating in nature. We believe that excluding the impact of accretion of interest on convertible senior notes allows for more meaningful comparisons between operating results from period to period as accretion of interest on convertible senior notes relates to interest cost for the time value of money and are non-operating in nature. We believe that excluding gain on extinguishment of convertible notes, capped call modification and change in fair value allows for more meaningful comparisons between operating results from period to period as gains and losses on the extinguishment of convertible notes, capped call modifications and change in fair value are non-operating in nature. We do not engage in the repurchase of convertible notes on a regular basis or in the ordinary course of business. Accordingly, we believe that excluding these expenses provides investors and management with greater visibility of the underlying performance of our business operations, facilitates comparison of our results with other periods and may also facilitate comparison with the results of other companies in our industry.

There are limitations in using non-GAAP financial measures because the non-GAAP financial measures are not prepared in accordance with GAAP, may be different from non-GAAP financial measures used by other companies and exclude expenses that may have a material impact upon our reported financial results. Further, stock-based compensation expense has been and will continue to be for the foreseeable future a significant recurring expense in our business and an important part of the compensation provided to our employees.

Adjusted EBITDA. Adjusted EBITDA represents our net loss before interest and investment income, net, provision for (benefit from) income taxes, depreciation and amortization expense, stock-based compensation expense, costs related to the 2022 Strategic Realignment, Anvil legal dispute accrual, change in fair value of contingent consideration and gain on extinguishment of debt, capped call modification and change in fair value. We do not consider these items to be indicative of our core operating performance. The items that are non-cash include depreciation and amortization expense, stock-based compensation expense, change in fair value of contingent consideration and gain loss on extinguishment of debt, capped call modification and change in fair value. Adjusted EBITDA is a measure used by management to understand and evaluate our core operating performance and trends and to generate future operating plans, make strategic decisions regarding the allocation of capital and invest in initiatives that are focused on cultivating new markets for our solutions. In particular, the exclusion of certain expenses in calculating adjusted EBITDA facilitates comparisons of our operating performance on a period-to-period basis. Adjusted EBITDA is not a measure calculated in accordance with U.S. GAAP. We believe that adjusted EBITDA provides useful information to investors and others in understanding and evaluating our operating results in the same manner as our management and the Board. Nevertheless, the use of adjusted EBITDA has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our financial results as reported under GAAP. Some of these limitations are: (1) although depreciation and amortization are non-cash charges, the capitalized software that is amortized will need to be replaced in the future, and adjusted EBITDA does not reflect cash capital expenditure requirements for such replacements or for new capital expenditure requirements; (2) adjusted EBITDA does not reflect changes in, or cash requirements for, our working capital needs; (3) adjusted EBITDA does not reflect the potentially dilutive impact of equity-based compensation; (4) adjusted EBITDA does not reflect tax payments or receipts that may represent a reduction or increase in cash available to us; and (5) other companies, including companies in our industry, may calculate adjusted EBITDA or similarly titled measures differently, which reduces the usefulness of the metric as a comparative measure. Because of these and other limitations, you should consider adjusted EBITDA alongside our other GAAP-based financial performance measures, net loss and our other GAAP financial results.

Free Cash Flow and Adjusted Free Cash Flow. Free cash flow represents net cash provided by operating activities minus 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. Free cash flow and adjusted free cash flow are measures used by management to understand and evaluate our core operating performance and trends and to generate future operating plans. The exclusion of capital expenditures, amounts capitalized for internally-developed software and cash payments for the 2022 Strategic Realignment facilitates comparisons of our operating performance on a period-to-period basis and excludes items that we do not consider to be indicative of our core operating performance. Free cash flow and adjusted free cash flow are not measures calculated in accordance with GAAP. We believe that free cash flow and adjusted free cash flow provide useful information to investors and others in understanding and evaluating our operating results in the same manner as our management and the Board. Nevertheless, our use of free cash flow and adjusted free cash flow have limitations as an analytical tool, and you should not consider them in isolation or as a substitute for analysis of our financial results as reported under GAAP. You should consider free cash flow and adjusted free cash flow alongside our other GAAP-based financial performance measures, net cash provided by operating activities, and our other GAAP financial results.

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.

2023 Advisory Vote on Executive Compensation and Shareholder Engagement

We hold a say-on-pay advisory vote on executive compensation annually. At our 2023 annual meeting, we provided shareholders with the opportunity to cast a non-binding vote on a proposal regarding the compensation of our NEOs for the year ended December 31, 2022. Of the votes cast, approximately 96% voted in favor of the proposal. We

were pleased with these results and believe it reflects our continuous efforts to engage with shareholders and solicit their feedback on our executive compensation program.

The Compensation Committee reviewed the final vote results for the proposal and, given the significant level of shareholder support and positive feedback received on recent program and governance changes, concluded that our executive compensation program continues to provide a competitive pay-for-performance package that effectively incentivizes the NEOs and encourages long-term retention. The Compensation Committee and, with respect to our CEO’s compensation, our Board, determined not to make any significant changes to our 2023 executive compensation policies or decisions as a result of the vote.

Everbridge Executive Compensation Program

Pay-for-Performance Focus

We believe that our executive compensation program for 2023 continued to tie incentive-based compensation metrics with the business objectives and corporate strategies that drive stockholder value creation. Our compensation strategy is focused on targeted business priorities that guide and align our actions to the needs of our customers, stockholders, and employees. To achieve this, our compensation program is designed to (1) attract and retain top talent that can continue building on our trajectory for long-term growth and profitability (2) provide competitive compensation packages that create a significant and substantial link between our business results, stockholder interests, and the individual employee’s pay opportunity.

To ensure pay-for-performance alignment, the Compensation Committee annually reviews the designs of our short- and long-term incentive compensation programs to confirm that they continue to promote a culture of responsible performance. The majority of total compensation opportunity offered to our executives comes in the form of an annual incentive bonus and equity awards granted under our long-term incentive (“LTI”) program, both of which represent “at risk” pay. Payouts of our annual bonus are dependent on our short-term business objectives, and equity awards include restricted stock units (“RSUs”) and performance-based restricted stock units (“PSUs”).

Compensation Philosophy

Our executive compensation program is designed to attract, motivate, and retain our key executives who drive our success and enable long-term stockholder value. We achieve these objectives by:

•

Providing a competitive pay opportunity;

•

Linking a significant portion of our NEOs’ target compensation to both short- and longer-term Company performance and strategic objectives;

•

Aligning our executives’ compensation with the interests of our stockholders by tying a significant portion of their total compensation opportunity to the value of our stock; and

•

Not encouraging unnecessary and excessive risk-taking, supported by our stock ownership requirements and executive compensation recovery (“clawback”) policy.

Our NEOs are highly specialized talent, which makes their retention a key priority. The Compensation Committee believes NEO compensation should be set at competitive levels to retain a valuable team and attract talent, while placing a strong emphasis on successful attainment of Company performance goals.

Compensation Program and Governance

The Compensation Committee is appointed by the Board to oversee our compensation policies, plans and programs, administration of our equity plans, and its responsibilities related to the compensation of our executive officers, directors, and senior management, as appropriate. A significant part of this oversight is aligning management interests with our business strategies and goals, as well as stockholder interests, while also mitigating excessive risk-taking. We continually take steps to strengthen and improve our executive compensation policies and practices.

Highlights of our current policies and practices include:


What We Do		What We Don’t Do
✔	Balance short- and long-term incentives to discourage short-term risk-taking at the expense of long-term results	✘	No guaranteed bonuses
✔	Grant 50% of long-term incentives with performance-vesting conditions	✘	No excise tax gross-ups
✔	Cap incentive payouts below 200% of target	✘	No hedging with respect to Everbridge shares
✔	Seek annual stockholder advisory approval on executive compensation	✘	No pledging of Everbridge shares
✔	Engage an independent advisor reporting directly to the Compensation Committee	✘	No short sales of Everbridge shares
✔	Subject incentive compensation to a “clawback” recoupment policy	✘	No transactions involving derivative securities instruments relating to Everbridge shares
✔	Maintain share ownership guidelines for directors and executives	✘	No excessive perquisites
✔	Annual risk assessment of compensation policies and programs	✘	No cash severance in excess of 2x target cash (annual base salary + target bonus)
		✘	No single trigger change in control payments

Elements of Compensation Program

Our executive compensation program primarily consists of annual base salary, an “at-risk” annual incentive bonus, time-vesting RSUs and “at-risk” PSUs, each of which is tied to our business strategy in the following manner:


Compensation Element	Link to Business Strategy	2023 Compensation Actions
Base Salary (See "Elements of Executive Compensation – Base Salary")	• Recognition of the individual’s role and responsibilities. • Competitive base salaries help attract, maintain, and motivate executive talent. • Increases are not automatic or guaranteed, which promote a performance-first culture.	• Increased cash salary of one NEO to better align compensation with market levels. • Recruited new executive team members.
Bonus Plan (See "Elements of Executive Compensation – Annual Cash Incentives – 2023 Bonus Plan Structure")	• Annual variable pay opportunities are designed to reward achievement of annual financial goals and individual achievement. • Metrics and targets are evaluated each year to ensure alignment with the overall Company business strategy.	• Corporate bonus plan structure measured to reflect revenue and Adjusted EBITDA metrics. • NEOs were paid bonus amounts based on 96% funding of bonus plan.
Long-Term Incentives (See "Elements of Executive Compensation – Long Term Incentives")	• Promotes an ownership culture and aligns the interests of executives with those of stockholders, as multi-year vesting period provides meaningful incentives for management to execute on longer-term financial and strategic growth goals that drive stockholder value creation. • Award mix and performance metrics are reviewed annually for strategic alignment with long-term stockholder value and business strategy. • Differentiating target award values based on individual performance, as well as overlapping vesting periods, helps motivate and retain key talent.	• LTI structure remained similar to 2022, with 50% granted as RSUs and 50% granted as PSUs. • PSU metrics were updated to include measures of Annual Recurring Revenue and Adjusted EBITDA.

Elements of Executive Compensation

Target total direct compensation for NEOs is comprised of base salary, annual cash incentives, and long-term incentives (both time and performance-vesting). In addition, each NEO is eligible for benefits that are generally offered to Everbridge employees.

Base Salary

Base salaries for our NEOs are established based on the individual’s scope of responsibilities, experience, and market factors. The Compensation Committee reviews base salaries on an annual basis, referencing peer group and survey data to understand the marketplace for individuals in similar positions.

The table below summarizes 2022 and 2023 base salaries for our NEOs:


Executive	2022 Base Salary	2023 Base Salary	% Increase
David Wagner	$425,000	$425,000	0.0%
Patrick Brickley	$375,000	$385,000	2.7%
Noah Webster	$360,000	$360,000	0.0%
John Di Leo (1)	—	$385,000	—
Bryan Barney	$400,000	$400,000	0.0%

(1) Mr. Di Leo joined the Company as Chief Revenue Officer on February 10, 2023.

Annual Cash Incentives – 2023 Bonus Plan Structure

Everbridge NEOs participate in an annual performance-based cash bonus plan as an incentive to achieve defined, quantitative corporate goals.

For 2023, the Compensation Committee established performance goals for the two bonus pool funding metrics – 50% Revenue and 50% Adjusted EBITDA . The results of these financial metrics are measured against the “Rule of 40” outcomes to determine the amount of funding for the bonus pool. The "Rule of 40" is a financial metric for software companies, and is measured by the sum of revenue growth percentage plus the adjusted EBITDA margin percentage. The qualification criteria for each of these performance goals were predetermined to align with our 2023 strategic priorities. In February 2024, the Compensation Committee approved a final bonus pool of 96% of target based on Revenue and Adjusted EBITDA performance, as displayed in the table below:

The Committee establishes an individual target for each NEO expressed as a dollar value (target bonus as a percentage of salary shown below for reference purposes), and the final bonus payout may range from 0% to 114% of the targeted payout level. When considering executives’ target bonus, the Committee evaluates market data as well as internal compensation parity among the executive team.


Financial Goals	Weight	Threshold	Target	Maximum	Actual Results	Actual Results
Revenue	50%	$444,600,000	$468,000,000	$533,520,000	$448,788,000	96% Achievement
Adjusted EBITDA	50%	$84,075,000	$88,500,000	$100,890,000	$84,858,000	96% Achievement
Bonus Funding		95.0%	100%	114.0%		96%


	Target Bonus	2023 Bonus Payout Range			Actual Payout
Executive	(% of Salary)	Threshold	Target	Maximum	(96% of Target)

David Wagner	100%	$403,750	$425,000	$484,500	$408,000
Patrick Brickley	75%	$274,313	$288,750	$329,175	$277,200
Noah Webster	50%	$171,000	$180,000	$205,200	$172,800
John Di Leo (1)	100%	$325,668	$342,808	$390,801	$329,096
Bryan Barney	75%	$285,000	$300,000	$342,000	$288,000

(1) Mr. Di Leo is eligible for a pro-rated bonus based on his February 10, 2023 hire date.

Long-Term Incentives

In 2022, the Compensation Committee adopted an annual LTI grant schedule for our existing executive officers. The Compensation Committee believes in a strong pay-for-performance program and culture that encourages management to align their long-term interests with those of Everbridge’s stockholders. To achieve this, the 2023 annual LTI grants to executives consisted of two equity vehicles:


LTI Award Type	Purpose	Vesting Terms
RSUs (50% of Target LTI)	Retain and motivate executives to drive long-term stockholder value while establishing personal ownership	Time-vesting in equal installments over 12 calendar quarters
PSUs (50% of Target LTI)	Reward executives for the achievement of multi-year performance goals directly linked to the long-term success of the Company	50% of the award eligible to vest (at 0% – 125% of target) at end of the fiscal quarter after the 2nd anniversary of grant based on (a) the preceding 8-quarter revenue compound annual growth rate (“CAGR”) of ARR achieved by the Company during the eight fiscal quarters preceding the then most recent fiscal quarter, weighted at 50% and (b) the Adjusted EBITDA weighted at 50%. 50% of the award eligible to vest (at 0% – 125% of target) at the end of the fiscal quarter after the 3rd anniversary of grant based on (a) preceding 12-quarter revenue CAGR of ARR achieved during the 12 fiscal quarters preceding the then most recent fiscal quarter weighted at 50% and (b) the Adjusted EBITDA weighted at 50%.

We believe that the growth rate of our ARR and adjusted EBITDA is a critical bellwether of our current operating results and long-term business prospects, and that the 2023 PSUs demonstrate pay-for-performance by supporting our comprehensive approach to growing Everbridge’s top line. The structure of these awards is an integral part of ensuring that our leadership team is focused on our key objectives and operating principles of our long-term strategy, and PSUs appropriately reward executives for financial achievement.

In 2023, our NEOs received LTI grants for the following dollar amounts:


Executive		2023 Annual RSUs ($)		2023 Annual PSUs ($)		Total 2023 Annual LTI ($)

David Wagner(1)	$	—	$	—	$	—
Patrick Brickley		922,705		922,705		1,845,410
Noah Webster (2)		—		981,067		981,067
John Di Leo		3,196,000		3,413,000		6,609,000
Bryan Barney(3)		—		3,413,000		3,413,000

(1) Mr. Wagner received a grant of 200,000 RSUs and 200,000 PSUs on December 31, 2021, and was ineligible for any LTI grants during 2023.

(2) Mr. Webster was granted 28,742 RSUs on December 30, 2023.

(3) Mr. Barney was granted 100,000 RSUs on December 30, 2023.

Treatment of RSUs and PSUs in Connection with the Proposed Merger.

In connection with the proposed Merger, all outstanding unvested RSUs will be converted into cash awards that will be subject to substantially the same vesting terms and conditions that applied to the unvested RSUs immediately prior to the effective time of the Merger. In addition, all outstanding PSUs will be converted into cash awards that will be subject to substantially the same vesting terms and conditions that applied to the unvested PSUs immediately prior to the effective time of the Merger, except that in lieu of vesting based on performance metrics, 50% of each converted PSU cash award will instead vest as target achievement at the end of the fiscal quarter which ends immediately after the second anniversary of the date of grant, and 50% of each converted PSU cash award will vest at target achievement at the end of the fiscal quarter which ends immediately after the third anniversary of the date of grant, subject in each case to continuous service through the applicable vesting date(s).

Vesting of PSUs

During 2023, Patrick Brickley vested 1,261 PSU shares. This vesting event occurred based on a previous PSU award with performance metrics based on our revenue CAGR for the 8-quarter and 12-quarter periods that ended during the 2023 fiscal year. At each vesting date, 50% of the award is eligible to vest (at 0% – 150% of target) based on preceding 8 or 12-quarter revenue CAGR. Each of the PSU awards that vested during 2023 represents one-half of the original PSU award vesting at an average of 20.6% of target. During 2023, no other NEOs had any PSU awards that were eligible for vesting.

Role of the Compensation Committee

The Compensation Committee seeks to ensure that our executive compensation program is properly rewarding and motivating our NEOs while aligning their goals with our business strategy and the interests of our stockholders. To do this, our Compensation Committee conducts an annual review of the aggregate level of our executive compensation and the mix of elements used to compensate our executive officers and historic compensation levels, including prior equity awards.

When setting executive compensation opportunities, the Compensation Committee considers several factors, including:

•

Each NEO’s role and responsibilities;

•

Achievement of key performance objectives and milestones;

•

Market factors, such as compensation practices of peer companies;

•

Compensation survey data, as applicable; and

•

Retention concerns.

Role of the CEO in Compensation Decisions

Our CEO typically evaluates the performance of other executive officers and other employees, along with the performance of the Company as a whole, against previously determined objectives, on an annual basis and makes recommendations to the Compensation Committee with respect to annual base salary adjustments, bonuses, cash performance incentives and annual equity awards for the other executives. The Compensation Committee exercises its own independent discretion in approving compensation for all executive officers and assessing corporate performance against the pre-established objectives. The CEO is not present during deliberations or voting with respect to his own compensation.

Role of the Independent Compensation Consultant

The Compensation Committee retains the services of third-party, independent executive compensation consultants as it sees fit in connection with Everbridge’s compensation programs and related policies. For 2023, the Compensation Committee continued to engage Frederic W. Cook & Co., Inc. (“FW Cook”) as its independent consultant.

As the independent compensation consultant, FW Cook reports directly to the Compensation Committee. The scope of FW Cook’s assistance on Everbridge’s compensation program design and pay setting includes, but is not limited to, the following services:

•

Providing the Compensation Committee with information on compensation-related trends and regulatory developments in the broader market;

•

Advising the Compensation Committee on appropriate peer companies for compensation pay levels, design practices, and relative performance comparisons; and

•

Assisting on compensation program design through data and information analyses.

The Compensation Committee has assessed the independence of FW Cook under applicable SEC and Nasdaq rules. After conducting this assessment and considering any potential conflicts of interest, the Compensation Committee concluded that FW Cook is independent and has no conflicts of interest.

Peer Group

The Compensation Committee believes that it is important to make decisions informed by the current practices of comparable public companies with which we compete for top talent.

In July 2022, the Compensation Committee reviewed a peer group of twenty companies. During that review, it was determined that four companies be removed (one due to an acquisition, and three others due to size alignment), resulting in the following 16 companies established as the recognized peer group.


2023 Compensation Peer Group
Appfolio	Blackline	Digital Turbine	Fastly
New Relic	OneSpan	PagerDuty	Ping Identity
PROS Holdings	Q2 Holdings	Rapid7	Smartsheet
Sprout Social	SPS Commerce	Upland	Workiva

When making executive compensation decisions, the Compensation Committee does not rely on the peer group alone but also considers other data sources and other factors. To supplement market data gathered from publicly disclosed filings of our peer group, the Compensation Committee also considers market compensation data from the Radford Global Technology Survey, which is reflective of the broader market in which Everbridge competes for talent. The identity of the companies comprising the survey data is not disclosed to, or considered by, the Compensation Committee in its decision-making process, and the Compensation Committee does not consider the identity of the companies comprising the Radford Global Technology Survey to be material for its executive compensation responsibilities.

Other Features of the Our Executive Compensation Program

Employment Agreements

The initial terms and conditions of employment for each of our named executive officers are set forth in employment offer letters and employment agreements. The terms of these letters and agreements are described in greater detail in the section titled “Employment Arrangements” below. Each of our named executive officers is an at-will employee.

Severance and Change in Control Benefits

Adoption of Severance Plan

On August 5, 2022, upon the recommendation of the Compensation Committee, our Board of Directors adopted the Severance Plan. The Severance Plan provides severance benefits to our CEO, Executive Vice Presidents, Senior Vice Presidents, and certain specifically designated Vice Presidents, in the event such individual’s employment is terminated in either a Qualifying Termination or a CIC Qualifying Termination, in each case as described below. The Severance Plan supersedes any severance benefits that a participant would have been entitled to under any pre-existing employment agreement between the individual and the Company. To receive any of the severance benefits under these agreements, the participant would be required to execute a release of claims against the Company within 55 days of the qualifying termination. A description of the Severance Plan, and description of the termination and change of control provisions in our equity incentive plans and equity award agreements is provided below under “Potential Payments upon Termination” and “Potential Payments Upon Change in Control.”

401(k) Plan, Employee Stock Purchase Plan, Welfare and Health Benefits

We maintain a tax-qualified retirement plan that provides eligible U.S. employees, including our named executive officers, with an opportunity to save for retirement on a tax-advantaged basis. Eligible employees may make voluntary contributions from their eligible pay, up to certain applicable annual limits set by the Code. In 2023, we matched 50% of employee contributions, up to the first 4% of eligible employee deferrals per calendar year for each employee. Employee contributions are immediately and fully vested. Company matching contributions vest ratably over three years. The 401(k) plan is intended to be qualified under Section 401(a) of the Code with the 401(k) plan’s related trust intended to be tax exempt under Section 501(a) of the Code.

In 2023 we offered our employees, including our executive officers, the opportunity to purchase shares of our common stock at a discount under our 2016 Employee Stock Purchase Plan (“ESPP”). Pursuant to the ESPP, all eligible employees, including the eligible named executive officers, may allocate up to the lesser of $25,000 annually or 15% of the participant’s base compensation for that year to purchase our stock at a 15% discount to the market price, subject to specified limits. We terminated our ESPP program in 2024, in anticipation of the closing of the Merger with Thoma Bravo.

In addition, we provide other benefits to our executive officers, including the named executive officers, on the same basis as to all of our full-time employees. These benefits include, but are not limited to, medical, dental, vision, group life, disability and accidental death and dismemberment insurance plans.

We design our employee benefits programs to be affordable and competitive in relation to the market, as well as compliant with applicable laws and practices. We adjust our employee benefits programs as needed based upon regular monitoring of applicable laws and practices and the competitive market.

Perquisites and Other Personal Benefits

Currently, we do not view perquisites or other personal benefits as a significant component of our executive compensation program. Accordingly, we do not generally provide perquisites or other personal benefits to our executive officers, including our NEOs, except in situations where we believe it is appropriate to assist an individual in the performance of his or her duties, to make our executive officers more efficient and effective, and for recruitment and retention purposes. We do, however, pay the premiums for term life insurance and disability insurance, make matching contributions to our 401(k) plan, and allow participation in our ESPP, subject to certain limitations, for all of our employees, including our NEOs. None of our named executive officers individually received perquisites or other personal benefits in fiscal 2023 that were, in the aggregate, $10,000 or more.

In the future, we may provide perquisites or other personal benefits in limited circumstances. All future practices with respect to perquisites or other personal benefits will be approved and subject to periodic review by the Compensation Committee.

Tax and Accounting Implications

Accounting for Stock-Based Compensation

Under Financial Accounting Standard Board Accounting Standards Codification Topic 718 (“ASC 718”), Compensation—Stock Compensation, we are required to estimate and record an expense for each award of equity compensation over the vesting period of the award. We record share-based compensation expense on an ongoing basis according to ASC 718.

Under Section 162(m) of the Code (“Section 162(m)”), compensation paid to each of our “covered employees” that exceeds $1 million per taxable year is generally non-deductible.

Although the Compensation Committee will continue to consider tax implications as one factor in determining executive compensation, it also looks at other factors in making its decisions and retains the flexibility to provide compensation for our named executive officers in a manner consistent with the goals of our executive compensation program, which may include providing for compensation that is not deductible due to the deduction limit under Section 162(m).

Other Compensation Policies and Practices

Equity Awards Grant Delegation Policy

The Compensation Committee has delegated authority to our Chief Executive Officer to grant equity awards to our employees (other than our executive officers), subject to the terms and conditions of an equity awards grant delegation policy. Such awards may be granted on scheduled grant dates to newly-hired employees or to existing employees in connection with a promotion or in recognition of their contributions to the Company. In each instance, the policy provides for a limitation on the maximum size of any such awards.

Stock Ownership Guidelines

In May 2021, the Board adopted equity ownership guidelines to further align the interests of our senior management and directors with those of our stockholders. Under the guidelines, executives are expected to hold common stock in an amount ranging from five times base salary for our Chief Executive Officer, to two times base salary for our other executive officers. Our directors are also expected to hold common stock in an amount equal to three times their current cash retainer fee for Board service.


Position	Guideline
CEO or Executive Chair	5x base salary
Other Named Executive Officers	2x base salary
Non-Employee Directors	3x annual cash retainer

For purposes of these guidelines, stock ownership includes shares for which the executive or director has direct or indirect ownership or control and unvested restricted stock units, but does not include unvested performance-based stock units. As of December 31, 2023, our named executive officers met or exceeded these guidelines.

Compensation Recovery or Clawback Policy

In March 2020, the Board adopted a clawback policy that provides the Board discretion to reduce the amount of future compensation (both cash and equity) payable to an executive officer of the Company for excess proceeds from incentive compensation received by such executive officer due to a material restatement of financial statements. The clawback period is the three-year period following the filing of any such restated financial statements with the SEC. On November 7, 2023, the Board adopted an Incentive Compensation Recoupment Policy (the “2023 Clawback Policy”) designed to comply with Section 10D of the Exchange Act and the NYSE clawback listing standards. The 2023 Clawback Policy applies to all incentive compensation that is received by a covered officer on or after October 2, 2023, and replaces and supersedes our prior clawback policy with respect to all incentive compensation that is received by a covered officer on or after the October 2, 2023. The prior clawback policy continues to apply to any incentive compensation that is received by a covered officer prior to October 2, 2023. A copy of the 2023 Clawback Policy has been filed as an exhibit to our Annual Report on Form 10-K for the year ended December 31, 2023.

Policy Prohibiting Hedging and Pledging of Our Equity Securities

Our insider trading policy prohibits our employees, including our executive officers and directors, from engaging in short sales, hedging of stock ownership positions, and transactions involving derivative securities relating to our common stock. In addition, our directors and executive officers and any person required to comply with the blackout periods or pre-clearance requirements under our insider trading policy are prohibited from pledging Company securities as collateral for loans and may not hold Company securities in margin accounts.
