Conviction · Low · more likely to lag the S&P 500 over the next three months
Wrong if: a daily close above $55.54
Note written ·
Price against the kill line
17.4% clear of its kill line on the 13 November 2026 close.
How to read this
This note expects the shares to lag the market, so its kill line sits above the price: a close above the red mark would prove the view wrong. Prices run from low on the left to high on the right. The dot is where the stock closed on 13 November 2026, left of the mark while it is below the line; a dot right of the mark has closed through it.
The scale is stretched near the line, so close calls are easy to see. More than 8% from the line, the stock reads well clear, with a hollow dot to show the figure is off the drawn scale.
The kill line is the research note's own test. The portfolio sells on business facts, not on a price. How the portfolio decides
Three months against the kill line
Daily closes, to . Red: the kill line, a daily close above $55.54, on record since 11 November 2026. The shares are down 8.1% since the close; the S&P 500 is down 2.1% over the same sessions. Figures in the note can cover a different window.
Kill line
A daily close above $55.54, the highest adjusted close of the last 126 sessions (1 July 2026), which would show the shares leading the S&P 500; an FCC grant of the license transfer before 28 February 2027 would also show the deal value arriving early.

The thesis
Iridium Communications trades as a claim on Rocket Lab's pending offer of $27.00 in cash plus Rocket Lab stock per share, so Rocket Lab's share price and the Federal Communications Commission (FCC) review set its value. The shares are more likely to lag the S&P 500 than lead it over the next three months. The FCC decision on the license transfer and Rocket Lab's price against its $67.50 collar floor settle it.
The rating is Low because the upside is capped by the deal terms. Rocket Lab closed at $58.86 on 9 November 2026 (Investing.com), below the $67.50 floor. Below that floor the exchange ratio is fixed at 0.4000 Rocket Lab shares, so Iridium's consideration moves $0.40 for every $1 move in Rocket Lab. Iridium's own results no longer drive the price.
Iridium closed at $47.29 on 11 November 2026. That is below the $54.00 per-share value set at signing on 29 June 2026 (Rocket Lab announcement). The market prices a deal that closes in mid-2027 at a stock component worth less than at signing, with FCC timing still open.
Rocket Lab's third-quarter report on 9 November 2026 did not change the deal terms. Management said the deal is fully financed, needs no further capital raise, and that regulatory approval is the remaining step, with no closing date given (Investing.com call transcript, 9 November 2026). The FCC pleading cycle closed with replies due 9 November 2026. No FCC grant had been reported as of 12 November 2026.
Bullish and bearish views on Iridium Communications Inc
The bull case on Iridium Communications Inc (IRDM), in brief: Rocket Lab revenue beat and backlog grew. The bear case: acquirer shares remain below the collar.
Bull case
- Rocket Lab revenue beat and backlog grew. Rocket Lab reported third-quarter revenue of $267.8 million against a $257.17 million consensus and a record backlog of about $3.57 billion (Investing.com and BigGo Finance, 9 November 2026). A stronger acquirer share price lifts the stock part of Iridium's consideration.
- Neutron demand is booked. Rocket Lab signed eight Neutron launches for about $515 million and said its first 16 Neutron launches are booked (Benzinga, SpaceQ, 9 November 2026). The order book supports Rocket Lab's shares even with the first flight in 2027.
- Antitrust and holder approvals are done. The Hart-Scott-Rodino waiting period expired at 11:59 p.m. ET on 12 August 2026 (prospectus, 26 August 2026), and Iridium's 8-K of 24 September 2026 records stockholder adoption of the merger agreement.
- Third-party filings stop short of opposition. SpaceX told the FCC on 28 August 2026 that it does not oppose the deal (MLex), and SatNews reported on 4 November 2026 that Globalstar's filing did not formally oppose it.
- Iridium's business keeps growing. Third-quarter revenue was $245.733 million against a $236.303 million estimate (results, 20 October 2026). The board plans to raise the quarterly dividend to $0.16 from $0.15 starting with the fourth-quarter 2026 dividend (Iridium Q3 release, 20 October 2026).
Bear case
- Acquirer shares remain below the collar. Rocket Lab's $58.86 close on 9 November 2026 sits under the $67.50 floor, and its shares fell 6.52% after hours that evening to $55.02 (Investing.com). Every Rocket Lab decline passes to Iridium at 0.4000 shares.
- Rocket Lab losses widened. Rocket Lab reported a loss of $0.12 a share against $0.07 expected for the third quarter and guided fourth-quarter adjusted EBITDA (earnings before interest, taxes, depreciation and amortization) to a loss of $14 million-$20 million (Investing.com, 9 November 2026).
- Neutron's first flight slipped to 2027. Rocket Lab cited voids found in a stage 1 propellant tank dome (SpaceQ, 9 November 2026). Rocket Lab fell nearly 10% in afternoon trading on 16 October 2026 when the delay was first disclosed (Light Reading).
- Third parties are testing the license transfer. Globalstar asked the FCC to review Rocket Lab's role as its main spacecraft bus supplier (SatNews, 4 November 2026), and SpaceX asked the agency to examine Iridium's conduct toward rival operators (MLex, 28 August 2026). Conditions or delay could push completion past mid-2027.
- No company guidance exists. Iridium suspended earnings calls and guidance on 22 July 2026, so the business is read only through filings until the deal closes.
Price setup
Iridium closed at $47.29 on 11 November 2026 after five straight higher closes from $42.02 on 5 November 2026. The 3-month change is −4.7%. The last close sits above the 50-day moving average of $46.41 and the 200-day moving average of $40.58, both as of 11 November 2026.
The quoted 52-week intraday high is $57.18 on 2 July 2026, two sessions after the deal announcement; the last close is 17.3% below it. The quoted 52-week closing low is $15.84 on 20 November 2025, before the deal. The $42.02 close of 5 November 2026 is the nearest recent low.
SEC Form 4 filings since October show director stock awards on 30 September 2026 and a gift of 42,800 shares by Chief Executive Officer Matthew Desch on 22 October 2026. None is an open-market purchase or sale.
Catalysts ahead
- ~26 February 2027 (est.): Rocket Lab fourth-quarter 2026 report. Rocket Lab guided Q4 revenue to $270 million-$290 million; its share price after the report sets the stock part of Iridium's consideration while below the $67.50 collar floor.
- 28 June 2027: Initial merger end date, extendable to 28 September 2027 and 28 December 2027. Marks the outer edge of the expected mid-2027 completion window; passing it with approvals pending triggers an extension rather than termination.
What would change the view
A daily close above $55.54, the highest adjusted close of the last 126 sessions (1 July 2026), which would show the shares leading the S&P 500; an FCC grant of the license transfer before 28 February 2027 would also show the deal value arriving early.
What it trades with
Iridium moves with Rocket Lab while Rocket Lab trades below $67.50. On 9 November 2026 Rocket Lab rose 10.91% to $58.86 (Investing.com) and Iridium closed at $45.08, up from $44.04 on 6 November 2026. The $27.00 cash portion damps the link, so Iridium swings less than Rocket Lab in percentage terms. Other satellite operators matter mainly through the FCC docket: SpaceX's direct-to-device approvals and Globalstar's supplier objection shape the review.
