Key points
- Six Iridium Communications (IRDM) insiders sold about $19.3 million in stock on August 17 and 18, none of it under a 10b5-1 trading plan.
- Rocket Lab agreed in June to buy Iridium for a notional $54 a share. The sales landed near $50, about 7% below that.
- Former CFO and current director Thomas Fitzpatrick sold 79% of his direct stake, worth $11.25 million, more than half the week's total.
- Chairman Robert Niehaus gave away 50,000 shares the same week. That was a gift, not a sale.
On August 19, six Iridium Communications (IRDM) insiders filed Form 4s with the SEC showing they'd sold stock over the last two trading days. The combined total comes to about $19.3 million, and every sale happened in the open market rather than through a prearranged Rule 10b5-1 plan.
What makes the timing worth a look is the price. In June, Rocket Lab agreed to acquire Iridium in a deal with a notional value of $54.00 a share: $27.00 in cash plus Rocket Lab stock, sized by a formula that holds the total near $54 as long as Rocket Lab trades between $67.50 and $112.50. Rocket Lab closed Wednesday at $75.84, comfortably inside that band. Iridium CEO Matt Desch called the combination "an incredible opportunity for our customers, partners, employees, and stockholders" when the deal was announced. Yet these insiders sold between $49.16 and $50.90 a share, an average of $50.23, about 7% under what the deal is supposed to be worth once it closes.
| Insider | Role | Shares sold | Value | Dates |
|---|---|---|---|---|
| Thomas Fitzpatrick | Director, former CFO | 224,279 | $11.25M | Aug 17 & 18 |
| Suzanne McBride | Director, Chief Operations Officer | 85,454 | $4.30M | Aug 17 |
| Kathleen Morgan | Chief Legal Officer | 33,192 | $1.67M | Aug 17 |
| Timothy Last | EVP, Sales & Marketing | 19,521 | $0.98M | Aug 17 |
| Timothy Kapalka | Chief Accounting Officer, Iridium Satellite LLC | 13,473 | $0.68M | Aug 17 |
| Eric Olson | Director | 8,000 | $0.40M | Aug 17 |
Thomas Fitzpatrick is the name that stands out. He ran Iridium's finance department for more than a decade, as CFO starting in 2010 and later CFO and chief administrative officer, before retiring from the executive role in December 2024 and staying on the board. Across the two days, he sold 224,279 shares for $11.25 million, cutting his direct holding from 282,585 shares to 58,306. That's about 79% of what he had.
Suzanne McBride, Iridium's chief operations officer and a board member herself, sold the second-largest block: 85,454 shares for $4.3 million, a bit under a quarter of her direct stake. General counsel Kathleen Morgan, sales and marketing head Timothy Last, satellite-subsidiary accounting chief Timothy Kapalka, and director Eric Olson made up the rest, each keeping the larger share of what they held going in.
There was a seventh filing that week, and it belongs in a different category. Board chairman Robert Niehaus, who has led Iridium's board since 2009 and runs the investment firm GCP Capital Partners, gave away 50,000 shares on August 17 at a stated price of zero, a gift rather than a sale. Gifted shares carry a different signal than a sale. Whoever received them can hold or sell on their own timeline, and Niehaus still directly holds about 267,000 shares of Iridium afterward.
Why sell into the market at a discount instead of waiting for the deal to close? The gap is smaller than the raw math suggests once you account for time. Iridium's shareholder vote hasn't happened yet. Regulatory clearance is still pending. Rocket Lab isn't expected to close the acquisition until mid-2027, close to a year away. A dollar of guaranteed cash today is worth more than a conditional $54 that far out. Fitzpatrick aside, none of the other five sold more than a quarter of what they held. We saw the same shape recently in Globalstar's insiders selling below Amazon's $90 buyout price, and satellite peer Viasat has shown a version of it too, without a pending deal attached.
Iridium's own preliminary merger proxy went to the SEC on August 13, four days before this selling started. The filings don't say whether that timing is connected, and there's no requirement that it would be, since the deal terms have been public since June 29. Iridium (IRDM) shares closed Wednesday at $48.71, below both the price these insiders sold at and the $54 the deal is supposed to deliver. What the Form 4s establish is the pattern itself: six insiders sold, one gave shares away, and nobody bought.
