NEW YORK, July 19, 2026, 12:08 (EDT) — Rocket Lab NASDAQ:RKLB shares were close to the $67.50 deal support level after declining 17% over the week.
- Rocket Lab ended trading on Friday at $67.62, only 12 cents higher than the lower limit of the takeover collar.
- Shares dropped by 16.6% last week, while the Nasdaq Composite declined 2.9%.
- Shares of Iridium Communications Inc. NASDAQ:IRDM finished 13.6% under the deal’s stated $54 consideration.
Rocket Lab Corporation closed Friday only slightly above the lower collar set for its proposed Iridium acquisition. This contract point is now in focus for the coming week.
Shares ended Friday at $67.62, rising 0.4% on the day but finishing the week 16.6% lower. U.S. equity markets did not open on Sunday.
The $8 billion deal represents roughly 20% of Rocket Lab’s market value as of Friday. The collar restricts the number of shares to be issued should Rocket Lab’s share price fall.
If the contractual price falls below $67.50, the exchange ratio is fixed at 0.4000. This limits the number of shares issued and lowers the value provided to Iridium holders.
The agreement bases the final ratio on a 10-day volume-weighted average price that ends two full trading sessions before closing, rather than Friday’s close. The deal is anticipated to complete in mid-2027.
The collar results in a payout that is not symmetrical:
| Example Rocket Lab VWAP | RKLB shares for each IRDM share | Estimated new RKLB shares | As percentage of June 25 common shares | Indicated value per IRDM share |
|---|---|---|---|---|
| $60.00 | 0.4000 | 42.4 million | 7.1% | $51.00 |
| $67.50 floor | 0.4000 | 42.4 million | 7.1% | $54.00 |
| $90.00 | 0.3000 | 31.8 million | 5.3% | $54.00 |
| $112.50 ceiling | 0.2400 | 25.4 million | 4.3% | $54.00 |
| $130.00 | 0.2400 | 25.4 million | 4.3% | $58.20 |
Initial estimates are based on 105.96 million Iridium shares and 598.18 million Rocket Lab common shares outstanding as of late June. These figures do not include awards, preferred shares, or subsequent changes.
If the floor is reached, Rocket Lab is set to issue approximately 42.4 million shares. At the ceiling, the number drops to nearly 25.4 million.
The distinction is significant. A reduced price increases the economic risk borne by Iridium holders. Rocket Lab’s share issuance no longer increases.
Iridium closed on Friday at $46.68, compared with the nominal offer price of $54. The gap highlights the extended timeline, need for approvals, financing issues and collar risk.
The decline extended beyond a single stock. Redwire Corporation NYSE:RDW slid 17.0% last week, while the Nasdaq dropped 2.9%. Rocket Lab’s losses were more significant as they neared a contractual threshold.
Rocket Lab reported positive operational developments, successfully conducting a nearly 5.5-minute full-duration burn of its vacuum Archimedes engine. This engine is set to propel the second stage of the Neutron rocket.
Peter Beck, Chief Executive, described the Iridium agreement as “a defining moment for the space industry.” Iridium posted 2.55 million subscribers and 2025 revenue of $871.7 million.
Rocket Lab posted first-quarter revenue of $200.3 million, with a backlog of $2.2 billion. The company forecast second-quarter revenue in the range of $225 million to $240 million.
Rocket Lab’s investor calendar lists no events this week. Investors are monitoring the $67.50 level, potential Neutron news, and the awaited S-4 filing. No filing date has been set.
Primary risks include Neutron delays, financing expenses, regulatory assessment, and approval from Iridium shareholders. Additional declines below the collar could lower the target value and make it harder to secure investor backing.
The $67.50 level does not serve as technical support. Rather, it reflects the point at which the agreement shifts the next dollar of price risk.
