| Item 8.01. | Other Events. |
On August 26, 2026, Iridium Communications Inc., a Delaware corporation (the “Company” or “Iridium”), filed its definitive proxy statement on Schedule 14A (as such may be supplemented from time to time, the “Proxy Statement”) with the Securities and Exchange Commission (the “SEC”) with respect to the special meeting of Iridium’s stockholders (the “Special Meeting”) to be held in connection with transactions contemplated by that certain Agreement and Plan of Merger (the “Merger Agreement”), dated as of June 28, 2026, by and among Iridium, Rocket Lab Corporation, a Delaware corporation (“Parent”), Ion Merger Sub I, Inc., a Delaware corporation and an indirect wholly owned subsidiary of Parent (“Merger Sub I”), and Ion Merger Sub II, LLC, a Delaware limited liability company and an indirect wholly owned subsidiary of Parent (“Merger Sub II”). Pursuant to the Merger Agreement, and subject to the satisfaction or waiver of the conditions set forth therein, Merger Sub I will merge with and into Iridium (the “First Merger”) with Iridium continuing as the surviving corporation and an indirect wholly owned subsidiary of Parent, and subject to certain specified conditions provided in the Merger Agreement being satisfied, immediately following the First Merger, the surviving corporation in the First Merger will merge with and into Merger Sub II, with Merger Sub II continuing as the surviving entity (the “Subsequent Merger” and together with the First Merger, the “Mergers”).
The Special Meeting is scheduled to be held on September 24, 2026, beginning at 8:30 a.m. Eastern Time. Iridium’s stockholders of record as of the close of business on August 21, 2026 will be eligible to vote at the Special Meeting. Subject to the satisfaction of the remaining conditions to closing of the Mergers under the Merger Agreement, including that Iridium’s stockholders vote to approve the Mergers at the Special Meeting, Iridium expects to complete the Mergers in mid-2027. The information contained in this Current Report on Form 8-K (this “Form 8-K”) should be read in conjunction with the Proxy Statement, which should be read in its entirety.
Litigation Relating to the Merger
As of the date of this Form 8-K, three lawsuits relating to the Mergers (collectively, the “Lawsuits”) have been filed in the Supreme Court of the State of New York, two in New York County and one in Suffolk County, respectively (Index No. 655039/2026; Index No. 655037/2026; and Index No. 626928/2026), by purported stockholders of the Company against the Company and members of the Company’s board of directors. The Lawsuits allege that, among other things, the Proxy Statement contains certain disclosure deficiencies and/or incomplete information regarding the Mergers and seek additional disclosures to remedy these purported deficiencies. The Lawsuits seek, among other relief, an order enjoining the consummation of the Merger. In addition to the Lawsuits, the Company has also received demand letters from purported stockholders of the Company (the “Demands,” and together with the Lawsuits, the “Matters”). The Demands allege similar deficiencies as those asserted in the Lawsuits and request that the Company issue corrective disclosures prior to the Special Meeting.
It is possible that additional, similar complaints may be filed, that the Lawsuits described above may be amended, or that additional demand letters will be received by the Company. If this occurs, the Company does not intend to announce the filing or receipt of each additional, similar complaint, demand letter, or any amended complaint, unless required by law.
The Company believes that the claims asserted in the Matters are without merit, that the disclosures set forth in the Proxy Statement comply with applicable law, rules and regulations and that no further disclosure beyond that already contained in the Proxy Statement is required under applicable law, rules or regulation. However, in order to moot the unmeritorious disclosure claims, to avoid nuisance, cost and distraction, and to preclude any efforts to delay the Special Meeting and the completion of the Mergers, the Company has determined to voluntarily supplement the Proxy Statement as described in this Form 8-K. Nothing in this Form 8-K shall be deemed an admission of the legal necessity or materiality under applicable laws of any of the disclosures set forth herein. To the contrary, the Company specifically denies all allegations set forth in the Matters that any additional disclosure in the Proxy Statement was or is required.
Supplemental Disclosures
The following disclosures supplement the disclosures contained in the Proxy Statement and should be read in conjunction with the disclosures contained in the Proxy Statement, which should be read in its entirety. To the extent the information set forth herein differs from or updates information contained in the Proxy Statement, the information set forth herein shall supersede or supplement the information in the Proxy Statement. All page references are to pages in the Proxy Statement, and terms used below, unless otherwise defined, have the meanings set forth in the Proxy Statement.
| (a) | In the section of the Proxy Statement titled “The Mergers—Summary of Evercore’s Financial Analyses—Analyses Relating to Iridium—Selected Precedent Transactions Analysis” the disclosure in the first full paragraph and the second full paragraph on page 85 is amended by replacing the paragraph with the following (new text is underlined and bold): |
Based on the multiples it derived from the selected transactions and based on its professional judgment and experience, Evercore selected and applied a TEV / LTM Adjusted EBITDA multiple reference range of 10.0x to 14.0x to Iridium’s estimated LTM Adjusted OEBITDA as of June 30, 2026 of approximately $527 million, as reflected in the Iridium Forecasts and Iridium’s financial results for the second half of 2025 as reported in its public filings, to derive a range of implied enterprise values for Iridium.
Based on these ranges of implied enterprise values, Iridium’s estimated net debt as of June 30, 2026 of approximately $2,102 million and the number of fully diluted shares of Iridium Common Stock as of June 24, 2026 of approximately 110.5 million, in each case as provided by Iridium’s management, this analysis indicated a range of implied equity values per share of Iridium Common Stock of $28.69 to $47.77, compared to the closing price of Iridium Common Stock of $28.52 per share on April 1, 2026 (the last trading day prior to a report by Financial Times regarding the acquisition of Globalstar by Amazon), the closing price per share of Iridium Common Stock of $43.52 on June 26, 2026, and the implied value of the Merger Consideration of $54.00 per share of Iridium Common Stock.
| (b) | In the section of the Proxy Statement titled “The Mergers—Summary of Evercore’s Financial Analyses—Analyses Relating to Iridium—Discounted Cash Flow Analysis” the disclosure in the last full paragraph on page 85 and the last paragraph beginning on page 85 is amended by replacing the paragraph with the following (new text is underlined and bold): |
Evercore performed a discounted cash flow analysis of Iridium to calculate the estimated present value of the unlevered, after-tax free cash flows that Iridium was forecasted to generate during Iridium’s fiscal years 2026 through 2035 based on the Iridium Forecasts. Evercore calculated terminal values for Iridium by applying a range of perpetuity growth rates of 2.5% to 3.5%, which range was selected by Evercore based on Evercore’s professional judgment and experience, to estimate the unlevered, after-tax free cash flows that Iridium was forecasted to generate in the terminal year of approximately $584 million, based on the Iridium Forecasts.
The cash flows and terminal values, in each case, were then discounted to present value as of June 30, 2026, using discount rates ranging from 9.0% to 10.0%, representing an estimate of Iridium’s weighted average cost of capital, as estimated by Evercore based on its professional judgment and experience, and based on the application of the capital asset pricing model, which requires certain company-specific inputs, including debt to total capitalization ratio, pre-tax cost of debt, and levered and unlevered betas, as well as certain financial metrics for the United States financial markets generally, to derive a range of implied enterprise values for Iridium. Based on these ranges of implied enterprise values, Iridium’s estimated net debt as of June 30, 2026, of approximately $2,102 million, the present value of Iridium net operating losses and R&D tax credit benefits of approximately $244 million as estimated by Iridium’s management (calculated using a discount rate of 11.0%, which was based on an estimate of Iridium’s cost of equity, as estimated by Evercore based on its professional judgment and experience) and the number of fully diluted shares of Iridium Common Stock as of June 24, 2026 of approximately 110.5 million, in each case as provided to Evercore by Iridium’s management, this analysis indicated a range of implied equity values per Iridium Common Stock of $29.97 to $45.54 compared to the closing price of Iridium Common Stock of $28.52 per share on April 1, 2026 (the last trading day prior to a report by Financial Times regarding the Amazon-Globalstar Transaction), the closing price per share of Iridium Common Stock of $43.52 on June 26, 2026, and the implied value of the Merger Consideration of $54.00 per share of Iridium Common Stock.
| (c) | In the section of the Proxy Statement titled “The Mergers—Summary of Evercore’s Financial Analyses—Analyses Relating to Rocket Lab—Selected Publicly Traded Companies Analysis” the disclosure in the last paragraph beginning on page 86 is amended by replacing the paragraph with the following (new text is underlined and bold): |
Based on these ranges of implied enterprise values, Rocket Lab’s estimated net debt as of June 30, 2026, and the number of fully diluted shares of Rocket Lab Common Stock of approximately 662.3 million, as provided by Rocket Lab management on June 24, 2026, this analysis indicated a range of implied equity values per share of Rocket Lab Common Stock of $61.22 to $99.03, based on Rocket Lab’s estimated revenue in 2027 and $53.10 to $101.69, based on Rocket Lab’s estimated revenue in 2028, compared to the closing price per share of Rocket Lab Common Stock of $84.54 on June 26, 2026.
| (d) | In the section of the Proxy Statement titled “The Mergers—Summary of Evercore’s Financial Analyses—Analyses Relating to Rocket Lab—Present Value of Future Share Price Analysis” the disclosure in the third full paragraph on page 87 is amended by replacing the paragraph with the following (new text is underlined and bold): |
In calculating the implied present value of the future price per share of Rocket Lab Common Stock, Evercore first calculated ranges of implied enterprise values of Rocket Lab by multiplying Rocket Lab’s estimated LTM revenue as of the end of calendar year 2031, based on the Rocket Lab Public Forecasts by an illustrative enterprise value to LTM revenue multiple range of 20.0x to 40.0x, which range was selected based on Evercore’s professional judgment and experience, to derive an implied future enterprise value reference range for Rocket Lab. Evercore then added to this range of implied enterprise values Rocket Lab’s net cash, in each case, as based on the Rocket Lab Public Forecasts, to calculate a reference range of implied future equity values for Rocket Lab. Evercore then divided the implied future equity values of Rocket Lab by an estimate of the number of fully diluted outstanding shares of Rocket Lab Common Stock as of the end of calendar year 2031 of approximately 671 million to calculate a reference range of implied future equity values per share for Rocket Lab. Evercore then discounted the implied future equity values per share to June 30, 2026 using discount rates ranging from 15.0% to 18.0%, as estimated by Evercore based on its professional judgment and experience, and based on the application of the capital asset pricing model, which requires certain company-specific inputs, including levered and unlevered betas, as well as certain financial metrics for the United States financial markets generally, which were based on an estimate of Rocket Lab’s cost of equity, as estimated by Evercore based on its professional judgment and experience. This analysis indicated a range of implied equity values per share of Rocket Lab Common Stock of $46.23 to $102.45, compared to the closing price of Rocket Lab Common Stock of $84.54 on June 26, 2026.
| (e) | In the section of the Proxy Statement titled “The Mergers—Summary of Evercore’s Financial Analyses—Other Factors—Equity Research Analyst Price Targets—Iridium” the disclosure in the last paragraph beginning on page 87 is amended by replacing the paragraph with the following (new text is underlined and bold; deletions are in bold and strikethrough text): |
Evercore reviewed selected public market trading price targets for the shares of Iridium Common Stock prepared and published by equity research analysts, that 10 of which were publicly available as of April 1, 2026 (the last trading day prior to a report by Financial Times regarding the Amazon-Globalstar Transaction) and 11 of which were publicly available as of June 26, 2026. These price targets reflect analysts’ estimates of the future public market trading price of the shares of Iridium Common Stock at the time the price target was published. As of April 1, 2026, the range of selected equity research analyst price targets per share of Iridium Common Stock was $16.00 to $40.00. As of June 26, 2026, the range of selected equity research analyst price targets per share of Iridium Common Stock was $16.00 to $60.00, in each case compared to the closing price of Iridium Common Stock of $28.52 per share on April 1, 2026 (the last trading day prior to a report by Financial Times regarding the Amazon-Globalstar Transaction), the closing price per share of Iridium Common Stock of $43.52 on June 26, 2026, and the implied value of the Merger Consideration of $54.00 per share of Iridium Common Stock. Public market trading price targets published by equity research analysts do not necessarily reflect current market trading prices for the shares of Iridium Common Stock and these target prices and the analysts’ earnings estimates on which they were based are subject to risk and uncertainties, including factors affecting the financial performance of Iridium and future general industry and market conditions.
