What changed: Deloitte Touche LLP filed Exhibit 23.3 consenting to the incorporation by reference of its audit reports dated February 26, 2026, regarding Rocket Lab Corporation's financial statements and internal controls for the fiscal year ended December 31, 2025. Why it matters: This consent is a procedural requirement for the Form S-4 registration statement facilitating the merger between Vector Acquisition Corp and Rocket Lab Corp, confirming the validity of the audited financial data included in the deal documentation.
What changed: A Rule 425 communication filed by Rocket Lab Corporation (Nasdaq: RKLB) in connection with its proposed acquisition of Iridium Communications Inc. The August 13, 2026 release states that the Hart-Scott-Rodino waiting period expired at 11:59 p.m. Eastern on August 12, 2026; that Rocket Lab filed its Form S-4 registration statement with the SEC on August 13, 2026 to register the equity consideration, which is not yet effective; and that Rocket Lab and Iridium filed applications with the FCC on August 10, 2026 seeking consent to transfer control of Iridium's licences and authorizations. Why it matters: Antitrust clearance is complete but the S-4 is not effective and the FCC has not consented, so the transaction's remaining conditions are regulatory and shareholder approval. The $3.6 billion bridge is a commitment the company intends to shrink; the Iridium facility amendment and the ATM are both stated intentions, and the lender consents have not been obtained.
What changed: Rocket Lab Corporation filed as Exhibit 1.1 an equity distribution agreement dated August 13, 2026 with Deutsche Bank Securities Inc. and Wells Fargo Securities, LLC as sales agents, forward sellers and/or principals, and Deutsche Bank AG, London Branch and Wells Fargo Bank, National Association as forward purchasers, for the issuance and sale from time to time of common stock having an aggregate gross sales price not to exceed $1,944,369,826 off an automatic shelf registration statement on Form S-3. Why it matters: This puts up to $1.94 billion of at-the-market equity capacity behind the Iridium purchase, and the forward-sale structure means shares can be borrowed and sold now with settlement deferred — the dilution is contracted before it appears in the share count. The proceeds are not ring-fenced: the agreement states on its face what happens to them if the acquisition does not close.
What changed: Rocket Lab Corporation filed as a 425 the unaudited pro forma condensed combined financial information for itself and Iridium Communications Inc. It restates the terms of the June 28, 2026 merger agreement: a two-step structure in which Merger Sub I merges into Iridium and, immediately afterwards, the surviving corporation merges into Merger Sub II, with the second merger occurring only if the tax conditions for a tax-free reorganization are met. Why it matters: The collar means an Iridium holder's stock consideration is fixed at 0.4000 shares below $67.50 and 0.2400 above $112.50 and floats only between those points, so the $27.00 cash leg is the only certain part of the price. The pro formas deliberately assume the most expensive financing outcome — the bridge, not the permanent debt the company says it intends to arrange — and note that possible amendments to Iridium's existing debt could reduce it, so the pro forma interest expense is an upper case. The bridge amount as printed is ambiguous against the document's own thousands caption.
What changed: Rocket Lab Corporation filed as Exhibit 99.3 to a Form 8-K the unaudited pro forma condensed combined financial information for itself and Iridium Communications Inc., the same document also filed under Rule 425. Why it matters: This is the 8-K that puts the combined-company pro formas on the record and fixes the assumptions a reader must adjust for: the bridge financing rather than the permanent financing the company intends to arrange, and no adjustment for possible amendments to Iridium's existing debt, which the document says are not yet determinable.
What changed: Rocket Lab Corporation filed a Form S-4 registration statement containing a preliminary proxy statement/prospectus for Iridium Communications Inc. stockholders, marked subject to completion. Under the June 28, 2026 merger agreement each Iridium share converts into $27.00 in cash plus Rocket Lab common stock at an Exchange Ratio of 0.4000 if the Rocket Lab Stock Price is $67.50 or less, $27.00 divided by that price between $67.50 and $112.50, and 0.2400 at or above $112.50. That price is a ten-consecutive-trading-day VWAP ending on the second full trading day before the First Effective Time. Why it matters: Filing the S-4 starts the SEC review that must complete before Iridium's stockholder vote, and the registration statement is expressly not yet effective, so no meeting date or record date exists. The document states plainly that the value of the merger consideration will fluctuate, because the collar fixes the exchange ratio only outside the $67.50–$112.50 band.
What changed: Rocket Lab filed a Rule 425 transcript from its Q2 2026 earnings call discussing its pending acquisition of Iridium Communications, which brings 66 satellites, 2.5M+ subscribers, and $870M+ annual revenue; the deal is expected to close mid-2027 pending stockholder and regulatory approvals. CEO Peter Beck emphasized growth in IoT, Direct-to-Device, advanced PNT, and defense markets, and indicated Iridium is a starting point for further space applications M&A. Why it matters: This is a post-SPAC acquirer (Rocket Lab, formerly VACQ) making a major strategic acquisition that transforms it into a vertically integrated space company spanning launch, satellite manufacturing, and space applications. The Iridium deal adds substantial recurring revenue and L-band spectrum assets, with closing expected mid-2027 subject to stockholder and regulatory approvals.
What changed: Rocket Lab entered into a merger agreement to acquire Iridium Communications on June 28, 2026 for $27.00/share cash plus stock at an exchange ratio of 0.24-0.40 depending on RKLB price, with a $3.6B bridge loan committed by Deutsche Bank and Wells Fargo; closing expected in 2027. The company also completed acquisitions of Mynaric AG ($160.8M), Motiv Space Systems ($44.5M), and GEOST ($292.1M), while raising $1.53B gross via ATM equity offerings and seeing $142.3M of its $355M convertible notes converted into 27.8M shares. Why it matters: The Iridium transaction represents a transformative acquisition that will require significant financing ($3.6B bridge loan plus stock issuance), materially expanding Rocket Lab's scope beyond launch and spacecraft into satellite communications infrastructure. Share count has grown from ~544M to ~598M outstanding in six months, with up to $3.0B in additional ATM capacity available, signaling continued dilution risk alongside rapid revenue growth ($434M H1 2026 vs. $267M H1 2025).
What changed: Rocket Lab reported Q2 2026 revenue of $234.1M (up from $144.5M YoY) and a net loss of $49.3M, with cash rising to $2.13B driven by $1.53B in ATM equity offering proceeds. Adjusted EBITDA loss narrowed to $8.8M from $27.6M YoY. Why it matters: Revenue nearly doubled year-over-year and gross margin improved to 41.5% non-GAAP, but the company remains unprofitable and is heavily reliant on ATM equity raises for its cash position. The $1.53B ATM raise signals ongoing capital-intensive growth funding rather than self-sustaining operations.
What changed: Rocket Lab Corporation, successor to Vector Acquisition Corp, entered an agreement and plan of merger on June 28, 2026 to acquire Iridium Communications Inc. through two merger subsidiaries. Each Iridium share converts into $27.00 in cash plus Rocket Lab shares at an exchange ratio that floats: 0.4000 if the Rocket Lab price is at or below $67.50, $27.00 divided by the price between $67.50 and $112.50, and 0.2400 at or above $112.50. Iridium is to be delisted from Nasdaq after the first merger. Why it matters: A de-SPAC company is now the acquirer in a large public-company merger, and the structure carries a tax condition worth reading closely: the deal is intended to be a tax-free reorganisation only if the stock consideration is large enough relative to the $27.00 cash, and the filing states that if those conditions are not met the second merger will not occur and the transaction will not qualify. The Rocket Lab price is the ten-day volume-weighted average ending two trading days before closing.
