1Adjusted EBITDA is a non-GAAP financial measure. Refer to "Non-GAAP Financial Measures" below.

This guidance consists of forward-looking statements and actual results may differ materially. Refer to the Forward-Looking Statements section below for information on the factors that could cause the Company’s actual results to differ materially from these forward-looking statements. Adjusted EBITDA is a non-GAAP financial measure. The Company has not provided the most directly comparable GAAP measure to this forward-looking non-GAAP financial measure because certain items are out of the Company’s control or cannot be reasonably predicted. Accordingly, a reconciliation for forward-looking Adjusted EBITDA is not available without unreasonable effort.

Telos will host a live webcast to discuss its fourth quarter and full year 2023 financial results at 8:30 a.m. Eastern Time today, March 15, 2024. To access the webcast, visit https://register.vevent.com/register/BI94c76586d2fc4af89e15cd30ebef71e1. Related presentation materials will be made available on the Investors section of the Company’s website at https://investors.telos.com. In addition, an archived webcast will be available approximately two hours after the conclusion of the live event on the Investors section of the Company’s website.

This press release contains forward-looking statements which are made under the safe harbor provisions of the federal securities laws. These statements are based on the Company’s management’s current beliefs, expectations and assumptions about future events, conditions, and results and on information currently available to them. By their nature, forward-looking statements involve risks and uncertainties because they relate to events and depend on circumstances that may or may not occur in the future. The Company believes that these risks and uncertainties include, but are not limited to, those described under the captions “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” set forth from time to time in the Company’s filings and reports with the U.S. Securities and Exchange Commission (“SEC”), including its Annual Report on Form 10-K for the year ended December 31, 2023 and its Quarterly Reports on Form 10-Q, as well as future filings and reports by the Company, copies of which are available at https://investors.telos.com and on the SEC’s website at www.sec.gov.

Although the Company bases these forward-looking statements on assumptions that its management believes are reasonable when made, the Company cautions the reader that forward-looking statements are not guarantees of future performance and that the Company’s actual results of operations, financial condition and liquidity, and industry developments may differ materially from statements made in or suggested by the forward-looking statements contained in this release. Given these risks, uncertainties, and other factors, many of which are beyond its control, the Company cautions the reader not to place undue reliance on these forward-looking statements. Any forward-looking statement speaks only as of the date of such statement and, except as required by law, the Company undertakes no obligation to update any forward-looking statement publicly, or to revise any forward-looking statement to reflect events or developments occurring after the date of the statement, even if new information becomes available in the future. Comparisons of results for current and any prior periods are not intended to express any future trends or indications of future performance, unless specifically expressed as such, and should only be viewed as historical data.

In addition to Telos' results determined in accordance with U.S. GAAP, Telos believes the non-GAAP financial measures of EBITDA, Adjusted EBITDA, EBITDA Margin, Adjusted EBITDA Margin, Adjusted Net Income/(Loss), Adjusted Earnings Per Share ("EPS"), Cash Gross Profit, Cash Gross Margin, and Free Cash Flow are useful in evaluating operating performance. Telos believes that this non-GAAP financial information, when taken collectively with GAAP results, may be helpful to readers of the financial statements because it provides consistency and comparability with past financial performance and assists in comparisons with other companies, some of which use similar non-GAAP financial information to supplement their GAAP results. The non-GAAP financial information is presented for supplemental informational purposes only, should not be considered a substitute for financial information presented in accordance with GAAP, and may be different from similarly-titled non-GAAP measures used by other companies. A reconciliation is provided below for each of these non-GAAP financial measures to the most directly comparable financial measure stated in accordance with GAAP.

Telos believes that EBITDA, EBITDA Margin, Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net(Loss)/Income and Adjusted EPS provide the Board, management and investors with a clear representation of the Company’s core operating performance and trends, provide greater visibility into the long-term financial performance of the Company, and eliminate the impact of items that do not relate to the ongoing operating performance of the business. Further, Adjusted EBITDA and Adjusted EBITDA Margin are used by the Board and management to prepare and approve the Company’s annual budget and to evaluate the performance of certain management personnel when determining incentive compensation. Cash Gross Profit and Cash Gross Margin provide management and investors a clear representation of the core economics of gross profit and gross margin without the impact of non-cash expenses and sunk costs expended. Telos uses Free Cash Flow to understand the cash flows that directly correspond with our operations and the investments the Company must make in those operations, using a methodology that combines operating cash flows and capital expenditures. Further, Free Cash Flow may be useful to management and investors in evaluating the Company's operating performance and liquidity. Telos believes these non-GAAP financial measures facilitate the comparison of the Company’s operating performance on a consistent basis between periods by excluding certain items that may, or could, have a disproportionately positive or negative impact on the Company’s results of operations in any particular period. When viewed in combination with the Company’s results prepared in accordance with GAAP, these non-GAAP financial measures help provide a broader picture of factors and trends affecting the Company’s results of operations.

EBITDA, Adjusted EBITDA, EBITDA Margin, Adjusted EBITDA Margin, Adjusted Net Income/(Loss), Adjusted EPS, Cash Gross Profit, Cash Gross Margin, and Free Cash Flow are supplemental measures of operating performance that are not made under GAAP and do not represent, and should not be considered as an alternative to, Net Income/(Loss), Net Income/(Loss) Margin, Earnings per Share, Gross Profit, Gross Margin, or Net Cash Flows provided by/(used in) operating activities, as determined by GAAP.

The Company defines EBITDA as net (loss)/income, adjusted for non-operating (income)/expense, interest expense, provision for/(benefit from) income taxes, and depreciation and amortization. The Company defines Adjusted EBITDA as EBITDA, adjusted for stock-based compensation expense and restructuring expenses. The Company defines EBITDA Margin, as EBITDA as a percentage of total revenue. The Company defines Adjusted EBITDA Margin as Adjusted EBITDA as a percentage of total revenue. The Company defines Adjusted Net Income/(Loss) as net income/(loss), adjusted for non-operating (income)/expense, stock-based compensation expense and restructuring expenses. The Company defines Adjusted EPS as Adjusted Net Income/(Loss) divided by the weighted-average number of common shares outstanding for the period. The Company defines Cash Gross Profit as gross profit, plus noncash charges for stock-based compensation expense, depreciation and amortization, as well as non-recurring items (such as restructuring expenses) charged under cost of sales. The Company defines Cash Gross Margin as Cash Gross Profit as a percentage of total revenue. Free Cash Flow is defined as net cash provided by/(used in) operating activities, less purchases of property and equipment, and capitalized software development costs.

EBITDA, Adjusted EBITDA, EBITDA Margin, Adjusted EBITDA Margin, Adjusted Net Income/(Loss), Adjusted EPS, Cash Gross Profit, Cash Gross Margin, and Free Cash Flow each has limitations as an analytical tool, and you should not consider any of them in isolation, or as a substitute for analysis of results as reported under GAAP. Among other limitations, EBITDA, Adjusted EBITDA, EBITDA Margin, Adjusted EBITDA Margin, Adjusted Net Income/(Loss), Adjusted EPS, Cash Gross Profit, Cash Gross Margin, and Free Cash Flow each does not reflect our cash expenditures, or future requirements, for capital expenditures or contractual commitments, does not reflect the impact of certain cash and non-cash charges resulting from matters considered not to be indicative of ongoing operations, and does not reflect income tax expense or benefit. Other companies in the Company’s industry may calculate Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net Income/(Loss), Adjusted EPS, Cash Gross Profit, Cash Gross Margin, and Free Cash Flow differently than Telos does, which limits its usefulness as a comparative measure. Because of these limitations, neither EBITDA, Adjusted EBITDA, EBITDA Margin, Adjusted EBITDA Margin, Adjusted Net Income/(Loss), Adjusted EPS, Cash Gross Profit, Cash Gross Margin nor Free Cash Flow should be considered as a replacement for Gross Profit, Gross Margin, Net Income/ (Loss), Net Income/(Loss) Margin, Earnings per Share, or Net Cash Flows Provided by Operating Activities, as determined by GAAP, or as a measure of profitability. Telos compensates for these limitations by relying primarily on the Company’s GAAP results and using non-GAAP measures only for supplemental purposes.

(1) The stock-based compensation adjustment to EBITDA is made up of stock-based compensation expense for the awarded restricted stock units (“RSUs”), performance-based restricted stock units (“PSUs”), stock options, and other sources. Stock-based compensation expense for the awarded RSUs, PSUs and stock options was $4.1 million and $22.9 million for the three and twelve months ended December 31, 2023, respectively, and $15.7 million and $62.5 million for the three and twelve months ended December 31, 2022, respectively. Stock-based compensation (adjustment)/expense from other sources was $(2.1) million and $1.5 million for the three and twelve months ended December 31, 2023, respectively, and $0.1 million and $2.1 million for the three and twelve months ended December 31, 2022, respectively. The other sources of stock-based compensation consist of accrued compensation, which the Company intends to settle in shares of the Company's common stock. However, it is the Company’s discretion whether this compensation will ultimately be paid in stock or cash. The Company has the right to dictate the form of these payments up until the date at which they are paid. Any change to the expected payment form would result in out-of-quarter adjustments to this add back to Adjusted EBITDA.

(2) The restructuring expenses include severance and other related benefit costs (including outplacement services and continuing health insurance coverage), external consulting and advisory fees related to implementing the restructuring plan.
