Innovation of Small Satellites, in a Transaction Valued at $1.58 Billion

NEW YORK, NY. and BOCA RATON, FL. (October 28, 2021) — Tailwind Two Acquisition Corp. (NYSE:TWNT) (“Tailwind Two”), a special purpose acquisition company, and Terran Orbital Corporation, the global leader and pioneer in the development, innovation and operation of small satellites and earth observation solutions, jointly announced today that they have entered into a definitive business combination agreement. Upon the closing of the transaction, the combined company (the “Company”) will operate as Terran Orbital Corporation, with plans to list on the NYSE under the symbol LLAP. The pro forma total enterprise value of the combined companies is approximately $1.58 billion. The transaction is expected to close in the first quarter of 2022.

The transaction is supported by gross proceeds of $345 million from Tailwind Two’s cash-in-trust, $50 million from a PIPE with participation from AE Industrial Partners, long-term Terran Orbital investor Beach Point Capital, Daniel Staton¹, Lockheed Martin and Fuel Venture Capital, as well as $75 million of additional financial commitments from Francisco Partners and Beach Point Capital. In connection with the closing of the transaction, up to an additional $125 million in debt commitments from Francisco Partners and Lockheed Martin may be available subject to certain conditions. Existing Terran Orbital shareholders will roll 100% of their equity into the combined company.

Terran Orbital is the pioneer and innovator of small satellites, with fully integrated operations, scale manufacturing and mission management capabilities. The company is the leading provider of small satellite solutions for military, intelligence community, civil and commercial customers. In addition, Terran Orbital is capitalizing on its fully integrated manufacturing capabilities to launch one of the most advanced earth observation constellation of small satellites, which will provide highly persistent, real-time earth imagery as a service, making earth observation data more abundant and accessible than ever before.

On September 27^th, Terran Orbital announced plans to develop a $300 million, 660,000 sq.ft. space manufacturing facility on the Space Coast of Florida. Upon completion, the newly constructed facility is expected to become one of the most advanced, largest vertically integrated satellite manufacturing facilities in the world, capable of producing over 1,000 satellites and space vehicles annually.

¹At closing and in return for a $30 million investment in the PIPE, an affiliate of Daniel Staton will receive a payment obligation equal to $30 million to be paid quarterly over four years with the first payment occurring at quarter end after transaction close; the first year’s payments are to be paid in cash and the remaining payments are to be paid in stock or, subject to certain conditions, in cash, at the discretion of the Company. Mr. Staton serves as a director of Terran Orbital and is an existing shareholder.

“Terran Orbital is the largest independently-owned manufacturer of small satellites in the United States, serving national interests and enabling our customers to leverage the strength of our platform and insights. With our high volume, innovative manufacturing of small satellites, we will be able to deliver emerging technologies to space faster, more affordably and with greater reliability than anyone. Fundamentally, we are creating the new SaaS, Satellites-as-a-Service,” said Marc Bell, Co-Founder and CEO of Terran Orbital. “In addition, our industry-leading earth observation constellation will deliver images of any geography on earth, at any time of day or night, within minutes. This capability will unlock a high-growth, high-margin data-as-a-service business model that will be truly transformational for Terran Orbital, its customers and investors.”

“Terran Orbital offers an outstanding solution to address the increasing demand for cost-effective data that is only available from space,” said Philip Krim, Chairman of Tailwind Two. “Tens of thousands of small satellites will be launched over the next decade, and Terran Orbital is ideally positioned to meet this demand, offering the most innovative, cost-effective small satellites that can meet the data demands for governments and corporations. Similarly, Terran Orbital’s own earth observation constellation will make the most technologically advanced data about our planet commercially available, which will unlock new markets for data and insights across industries.”

“At Lockheed Martin, supporting our customers’ missions means not only delivering the most innovative products and services, but also collaborating with future-forward teams,” said Rick Ambrose, Executive Vice President, Lockheed Martin Space. “We actively pursue working with organizations that are developing disruptive technologies and leveraging alternative business models. Our experience with Tyvak, which is part of Terran Orbital, has helped us expand our core capabilities to enable hybrid, networked architectures and we look forward to continuing to work together for the benefit of our customers.”

“Small satellites will play a critical role in the future of space infrastructure and exploration, as well as provide customers with real time data to make informed and actionable decisions,” said Kirk Konert, Partner at AE Industrial Partners. “Terran Orbital is entering into commercial partnerships with BigBear.ai and Redwire to develop and enhance next generation artificial intelligence and space solutions offerings, which is why we’re pleased to back the company and support its future growth.”

The Company and Tailwind are under no obligation to update, amend or supplement this Presentation or any information contained herein. This Presentation includes certain forward-looking statements, estimates, and projections provided by the Company that reflect management’s views regarding the anticipated future financial and operating performance of the Company. Forward-looking statements are statements that are not historical, including statements regarding operational and financial plans, terms and performance of the Company and other projections or predictions of the future. Forward looking statements are typically identified by such words as “project,” “believe,” “expect,” “anticipate,” “intend,” “estimate,” “may,” “will,” “should,” and “could” and similar expressions. Such statements, estimates, and projections reflect numerous assumptions concerning anticipated results. Forward-looking statements in this Presentation may include, for example; statements about the Company’s industry and market sizes; future opportunities; expectations and projections concerning future financial and operational performance and results of the Company; and the Potential Transactions, including items such as the implied enterprise value, ownership structure, the amount of redemption requests made by Tailwind’s shareholders, the ability of Tailwind to issue equity or equity-linked instruments in connection with the Potential Transactions or in the future, the likelihood and ability of the parties to successfully consummate the Potential Transactions, and those factors set forth on page 35 of this Presentation in the section entitled "Risk Factors" and "Cautionary Note Regarding Forward-Looking Statements" in Tailwind's final prospectus relating to its initial public offering dated March 8, 2021, and in subsequent filings with the Securities and Exchange Commission ("SEC"), including the proxy statement/prospectus relating to the Potential Transaction expected to be filed by Tailwind. As these assumptions may or may not prove to be correct and there are numerous factors which will affect the Company’s actual results (many of which are beyond the Company’s control), there can be no assurances that any projected results are attainable or will be realized. The Company, Tailwind and the Placement Agent disclaim any intention or obligation to update or revise any forward-looking statements whether as a result of new information, future events, or otherwise. The Company’s actual results may differ materially from those set forth in this Presentation.

35 Risk Factors The risks presented below are certain of the general risks related to the Company’s business, industry and ownership structure and are not exhaustive. The list below is qualified in its entirety by disclosures contained in future filings by the Company, or by third parties with respect to the Company, with the United States Securities and Exchange Commission (“SEC”). These risks speak only as of the date of this presentation and neither Tailwind nor the Company makes any commitment to update such disclosure. The risks highlighted in future filings with the SEC may differ significantly from, and will be more extensive than, those presented below. ⚫ The conditions for the availability of borrowings under the New Term Loan Facility, including the conditions for the Delayed Draw Loans, may not be satisfied. In addition, the consent of Francisco Partners may be required for borrowings under the New Term Loan Facility in certain circumstances. ⚫ The Company is an early-stage company with a history of losses and may never become profitable. ⚫ The Company’s operating and financial results forecast relies in large part upon assumptions and analyses that it has developed. If these assumptions or analyses prove to be incorrect, the Company’s actual operating and financial results may be significantly below its forecasts. ⚫ The Company has a limited operating history and operates in a rapidly evolving industry, which makes it difficult to evaluate its business and future prospects and increases the risk of your investment. ⚫ The Company will incur significant expenses and capital expenditures in the future to execute its business plans, including the development of its Earth Observation constellation, and it may be not be able to adequately control its expenses. ⚫ The Company relies on contracts with US government entities for a substantial portion of its revenues, and its business with various governmental entities is concentrated in a small number of primary contracts. The loss or reduction in scope of any one of its primary contracts would materially reduce its revenue. Government customers subject the Company to risks including early termination, audits, investigations, sanctions and penalties. ⚫ Lockheed Martin Corporation (“Lockheed Martin”) accounts for a substantial portion of the Company’s revenue and the Company has entered into a number of transactions with Lockheed Martin, including a strategic cooperation agreement. If Lockheed Martin changes its business strategy or reduces its demand for the Company’s products and services, the Company’s business, prospects, operating results and financial condition could be adversely effected. ⚫ The Company may need additional capital to pursue its business objectives and respond to business opportunities, challenges or unforeseen circumstances, and there can be no assurance that additional financing will be available, which could limit the Company’s ability to grow and jeopardize the Company’s ability to continue its business operations. ⚫ The Company’s Earth Observation constellation is in development and may not be completed on time or at all and the costs associated with it may be greater than expected. ⚫ Rapid and significant technological changes could render the Company’s Earth Observation constellation obsolete and impair its ability to compete. ⚫ The Company is highly dependent on the services of Marc Bell, its co-founder and Chief Executive Officer, and Tony Previte, its co-founder and Chief Strategy Officer and Executive Vice President, and if the Company is unable to retain Mr. Bell and Mr. Previte, attract and retain key employees and hire qualified management, technical and engineering personnel, its ability to compete could be harmed. ⚫ A failure to successfully develop and manage the Company’s proposed manufacturing facility could harm its business, financial condition and results of operations. ⚫ If the Company fails to manage its future growth effectively, its business, prospects, operating results and financial condition may be materially adversely effected. ⚫ The Company relies on third parties for a supply of equipment, satellite components and other services. ⚫ The Company and its suppliers rely on complex systems and components, which involves a significant degree of risk and uncertainty in terms of operational performance and costs. ⚫ The Company may be negatively affected by global economic conditions. ⚫ The ongoing COVID-19 pandemic may disrupt the Company’s operations, including its ability to successfully complete the research and development of its Earth Observation constellation on a timely basis. ⚫ The Company may not be able to launch its satellites successfully. Loss of a satellite during launch could cause significant danger on the ground and could delay or impair the Company’s ability to offer its services or reduce its expected potential revenues, and launch insurance, even if it is available, will not fully cover these risks. ⚫ The Company’s solutions could fail to perform or could perform at reduced levels of service because of technological malfunctions or deficiencies, regulatory compliance issues, or events outside of its control, which would harm its business and reputation. ⚫ The Company’s satellites have a limited life and may fail prematurely, which would materially and adversely affect its business, prospects and potential profitability. ⚫ The Company’s business may be adversely affected if it is unable to protect its intellectual property rights from unauthorized use by third parties. ⚫ The Company’s customized hardware and software may be difficult and expensive to service, upgrade or replace. ⚫ The Company’s networks and those of its third-party service providers may be vulnerable to security risks. ⚫ The Company’s satellites may collide with space debris or another spacecraft, which could adversely affect its ability to provide its satellite solutions and mission solutions. ⚫ Operation of satellites involves a degree of inherent risk. The Company could suffer significant reputational harm to its businesses, in addition to tort liability, maintenance, increased safety infrastructure and other costs stemming from any accident involving its satellite and mission solutions. ⚫ The Company’s business is subject to extensive government regulation, which mandates how it may operate its business and may increase the cost of providing services and expansion into new markets, and is subject to changes in regulatory requirements and other applicable laws. ⚫ The Company may become involved in or subject to litigation, including securities class action or derivative litigation, or investigations by the SEC or other regulatory authorities relating to the proposed business combination. ⚫ The Company identified material weaknesses in its internal control over financial reporting. If Terran is unable to remediate these material weaknesses, or if it identifies additional material weaknesses in the future or otherwise fails to maintain effective internal control over financial reporting, its business could be adversely affected. ⚫ The Company’s business could be impacted by the inability of the parties to successfully or timely consummate the proposed business combination, including the risk that any required regulatory approvals are not obtained, are delayed, or are subject to unanticipated conditions that could adversely affect the combined company or the expect ed benefits of the proposed business combination or that the approval of the shareholders of Tailwind is not obtained. ⚫ If the business combination benefits do not meet the expectations of investors or securities analysts, the market price of Tailwind’s securities or, following the closing, the combined entity’s securities, may decline.

39 Non-GAAP Financial Measures This Presentation includes non-GAAP financial measures, such as Adjusted Gross Profit, Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Free Cash Flow and Unlevered Adjusted Free Cash Flow, that have not been prepared in accordance with United States generally accepted accounting principles (“GAAP”). The non-GAAP measures in this Presentation may be different from non-GAAP calculations made by other companies. The recipient should be aware that the presentation of these measures may not be comparable to similarly-titled measures used by other companies. These measures may exclude items that are significant in understanding and assessing the Company’s financial results. Therefore, these measures should not be considered in isolation or as an alternative to net income or other measures of financial performance or liquidity under GAAP. Please refer to the last slide of this Presentation for a reconciliation of such non-GAAP measures to their most directly comparable measures presented in accordance with GAAP. The Company is not providing a reconciliation of Adjusted Gross Profit, Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Free Cash Flow and Unlevered Adjusted Free Cash Flow on a forward-looking basis to the most directly comparable measure prepared in accordance with GAAP because the Company is unable to provide this reconciliation without unreasonable effort due to the uncertainty and inherent difficulty of predicting the occurrence, the financial impact, and the periods in which the adjustments may be recognized. For the same reasons, the Company is unable to address the probable significant of the unavailable information, which could be material to future results. Adjusted Gross Profit We believe that the presentation of Adjusted Gross Profit is appropriate to provide additional information to investors about our gross profit adjusted for certain non-cash items. Further, we believe Adjusted Gross Profit provides a meaningful measure of operating profitability because we use it for evaluating our business performance, making budgeting decisions, and comparing our performance against that of other peer companies using similar measures. We define Adjusted Gross Profit as gross profit adjusted for (i) share-based compensation expense and (ii) depreciation and amortization. There are material limitations to using Adjusted Gross Profit. Adjusted Gross Profit does not take into account all items which directly affect our gross profit. These limitations are best addressed by considering the economic effects of the excluded items independently and by considering Adjusted Gross Profit in conjunction with gross profit as calculated in accordance with GAAP. Adjusted EBITDA and Adjusted EBITDA Margin We believe that the presentation of Adjusted EBITDA and Adjusted EBITDA Margin is appropriate to provide additional information to investors about our operating profitability adjusted for certain non-cash items, non-routine items that we do not expect to continue at the same level in the future, as well as other items that are not core to our operations. Further, we believe Adjusted EBITDA and Adjusted EBITDA Margin provide a meaningful measure of operating profitability because we use them for evaluating our business performance, making budgeting decisions, and comparing our performance against that of other peer companies using similar measures. We define Adjusted EBITDA as net income or loss adjusted for (i) interest, (ii) taxes, (iii) depreciation and amortization, (iv) share-based compensation expense, and (v) other non-recurring and/or non-cash items. We define Adjusted EBITDA Margin as Adjusted EBITDA divided by Revenue. There are material limitations to using Adjusted EBITDA and Adjusted EBITDA Margin. Adjusted EBITDA does not take into account certain significant items, including depreciation and amortization, interest, taxes, and other adjustments which directly affect our net income or loss. These limitations are best addressed by considering the economic effects of the excluded items independently and by considering Adjusted EBITDA in conjunction with net income or loss as calculated in accordance with GAAP. The Adjusted EBITDA discussion above is also applicable to Adjusted EBITDA Margin. Adjusted Free Cash Flow We believe that the presentation of Adjusted Free Cash Flow is appropriate to provide additional information to investors about our ability to service and repay debt and other payment obligations, make other investments, and pay dividends. We define Adjusted Free Cash Flow as cash flows from operating activities less cash outlays related to capital expenditures (which primarily relate to purchases of property, plant and equipment) adjusted for other payments or receipts that may mask our operating results or business trends. As a result, subject to the limitations described below, Adjusted Free Cash Flow is a useful measure of our cash flow attributable to our normal business activities, as well as our ability to service and repay debt and other payment obligations, make other investments, and pay dividends. Adjusted Free Cash Flow adjusts for cash items that are ultimately within management’s discretion to direct, and therefore, may imply that there is less or more cash that is available than the most comparable GAAP measure. Adjusted Free Cash Flow is not intended to represent residual cash flow for discretionary expenditures since debt repayment and other payment obligation requirements and other non-discretionary expenditures are not deducted. These limitations are best addressed by using Adjusted Free Cash Flow in combination with the GAAP cash flow numbers. Unlevered Adjusted Free Cash Flow We define Unlevered Adjusted Free Cash Flow as Adjusted Free Cash Flow adjusted for cash interest paid. As a result, subject to the limitations described below, Unlevered Adjusted Free Cash Flow is a useful measure of our cash available to service and repay debt and other payment obligations, make other investments, and pay dividends. Unlevered Adjusted Free Cash Flow adjusts for contractual interest and other obligation payments as well as cash items that are ultimately within management's discretion to direct, and therefore, may imply that there is less or more cash that is available than the most comparable GAAP measure. Unlevered Adjusted Free Cash Flow is not intended to represent residual cash flow for discretionary expenditures since debt repayment and other payment obligation requirements and other non-discretionary expenditures are not deducted. These limitations are best addressed by using Unlevered Adjusted Free Cash Flow in combination with the GAAP cash flow numbers. Source: Company management.
