Iridium Q3 2026 Earnings: $106.9M Net Income Built on a $103.9M Paper Gain

Iridium's third quarter of 2026 nearly tripled net income to $106.9 million, or $0.98 per diluted share — and $103.9 million of it never touched cash. The gain is the accounting remeasurement of the 39.5% Aireon stake Iridium already owned, booked on July 2 when it bought the rest of the space-based air-traffic surveillance company. Strip it out and the quarter tells a flatter story: operating income fell 55% to $31.6 million, OEBITDA slipped 1% to $135.6 million, and 9-month operating cash flow declined 3% to $281.7 million — while the pending Rocket Lab acquisition cleared its stockholder vote with 99.6% in favor and a mid-2027 close now the base case.

The Headline Numbers​

Every figure below comes from the Form 10-Q and the earnings release (8-K exhibit 99.1). The quarter's defining feature is the gap between the top and bottom lines: revenue grew a solid 8%, while reported net income grew 188% on a gain that will not repeat.

The deltas reveal a quarter where everything operating went sideways or backwards while one non-cash line did all the work. Service revenue grew 13% and now makes up 76% of total revenue — the mix shift toward recurring subscriptions is real. But selling, general and administrative expense more than doubled, from $35.5 million to $74.9 million, on deal costs; depreciation and amortization rose 17% as Aireon's intangibles began amortizing; and interest expense climbed 19% on the debt taken on to buy Aireon. The result: income before taxes and the equity gain collapsed from $47.9 million to $5.2 million. Then the $103.9 million remeasurement gain landed below that line and rescued the quarter. This is the quarter in one sentence: the business earned $5.2 million before tax, and the accountants earned $103.9 million.

Revenue Deep Dive​

Commercial service is the company — 65% of total revenue — and within it, one line absorbed the entire Aireon acquisition.

Hosted payload and other data service revenue jumped $22.7 million, or 121%, and the release attributes it plainly: "primarily due to the acquisition of Aireon." Aireon contributed $34.5 million of revenue in its first consolidated quarter — more than the segment's total growth, which means the pre-existing hosted-payload base shrank underneath. That is worth watching next quarter: the acquired growth is masking an organic decline in the highest-growth line.

IoT remains the subscriber engine. Commercial IoT subscribers grew 9% to 2.163 million, and IoT revenue grew 4% to $48.7 million — but IoT ARPU fell 4% to $7.63, and broadband ARPU fell 7% to $246 while broadband revenue dropped 9%. Iridium is adding connections faster than dollars, the classic wholesale-IoT tradeoff. Voice and data, the legacy line, lost 3% of revenue on a shrinking subscriber base, with ARPU flat at $48.

Government service grew 2% to $27.6 million on contractual rate increases in the EMSS contract, and the U.S. Space Force exercised its option to extend that contract through March 2027 at the same rate on September 11. The release says Iridium "continues to expect a renewal of the EMSS Contract in 2027." The government is still the largest single customer at 15% of service revenue, and the renewal — not this quarter's 2% — is the government story that matters.

Outside services, the other two lines both shrank: subscriber equipment fell 11% to $19.0 million, and engineering and support slipped 2% to $39.2 million. Neither moves the thesis, but both confirm that services — now consolidating Aireon's surveillance revenue — carry the growth.

On the management-signal scan, this release is strikingly quiet. There is no demand-exceeds-supply language, no pricing-momentum claim, no upcycle call — and the ARPU table explains why, with two of three ARPUs declining. The one forward signal with numbers behind it is subscriber growth: 69,000 net adds in the quarter versus 59,000 a year ago, led by commercial IoT. CEO Matt Desch's only quoted words concern the merger: "Last month's stockholder approval for Rocket Lab's acquisition of Iridium was an important milestone in creating a next generation space powerhouse." When the CEO's quote is about the acquirer, the quarter's operating story is, by definition, not the story.

The Margin Story​

Iridium's margins compressed on every operating measure this quarter, and the mechanics are fully visible in the filing.

Operating margin more than halved, from 30.9% to 12.9%, and the cause is line-item clear: SG&A rose $39.4 million while revenue rose $18.8 million. The OEBITDA reconciliation identifies $21.3 million of transaction-related expenses in the quarter, and Note 11 says $14.9 million of Aireon acquisition-related costs ran through SG&A. Deal costs, in other words, exceed the quarter's entire revenue growth. That is temporary by nature — but the Rocket Lab transaction has not closed, so transaction expenses have further to run.

Net margin, meanwhile, printed a gaudy 43.5% — up from 16.4% — entirely on the non-cash gain. The GAAP-to-OEBITDA bridge, which the release provides, is the honest version of this quarter and deserves to be read in full: start with $106.9 million of net income, add back $26.8 million of interest, $2.2 million of tax, $62.1 million of depreciation and amortization, $20.2 million of share-based compensation and $21.3 million of transaction expenses — then subtract the $103.9 million equity-method gain — and you arrive at $135.6 million of OEBITDA, down $1.0 million year over year. Every add-back grew; the gain is the only reason net income did not fall with them.

One more margin mechanic: the effective tax rate hit 41.9% in the quarter (versus 20.9% a year ago), which Note 12 attributes to acquisition costs, stock-compensation items and nondeductible executive pay. On $5.2 million of pre-tax income that barely registers in dollars — $2.2 million of tax — but it is another way the deals are taxing the P&L.

The One Big Question: What Is This Company Worth to Rocket Lab?​

With the merger approved by stockholders and expected to close by mid-2027, trailing earnings are trivia and the merger consideration is the valuation. The June 28 merger agreement pays each Iridium share $27.00 in cash plus Rocket Lab stock on a collar: 0.4000 shares if Rocket Lab trades at or below $67.50, a fixed $27.00 of stock value between $67.50 and $112.50, and 0.2400 shares at or above $112.50. At the midpoint of the collar that is roughly $54 of value per share — half cash, half acquirer equity.

The stockholder vote removes the main gating risk: 99.6% of votes cast favored the deal, representing 81.4% of outstanding shares. What remains is regulatory approval and closing conditions — the release's words — plus the ordinary risk that a space-merger review runs long. The balance sheet already reads like a company in transit: no share repurchases in the first nine months of 2026 (versus $186.5 million a year earlier), a $100 million revolver draw ahead of the Aireon close with $50 million still outstanding, net debt up to $2.06 billion, and net leverage at 4.2 times trailing OEBITDA.

The bull-bear question for the stub period is therefore narrow: does anything break the thesis before mid-2027? The EMSS renewal in 2027 is the one operating event that could — a lost or repriced government contract would dent the recurring base Rocket Lab is buying. The September extension through March 2027 at the same rate is a positive interim data point, not a resolution.

Tracking a $3.1 Billion Company in Plain Text​

A satellite company is hard to hold in your head: the constellation depreciates over 17.5 years, the debt funds the birds, and the equity stakes periodically detonate non-cash gains through the income statement. Modeling it in Beancount forces every one of those dollars to reconcile — the balance sheet must tie, and the income statement must sum to zero. That discipline is the whole point, and it is how we model every company.

Here is the quarter as the ledger records it — one zero-sum transaction, Income negative and Expenses positive, with the arithmetic check above it:

; FY2026Q3 Income Statement — three months ended September 30, 2026
; Net income as filed: 106,896 USD thousands (wholly attributable to common stockholders; no NCI)
; Check: -245.733 + 72.275 + 4.810 + 74.936 + 62.094 + 26.788 + 2.186 - 0.384 - 103.868 + 106.896 = 0 ✓

The balance-sheet number that tells the narrative is intangible assets: $86.9 million at the end of 2025, $361.9 million nine months later — the $285.1 million of Aireon customer relationships, developed technology and trade name now sitting on the books, amortizing over 4 to 13 years. Goodwill nearly tripled alongside it, from $98.9 million to $266.1 million. And the other side of the deal is visible too: short-term secured debt leapt from $3.4 million to $214.3 million, carrying the non-interest-bearing seller note that matures one year after closing.

The Multi-Year Arc​

Three years of audited and quarterly numbers show a company that repaired its P&L with an accounting estimate, then bought growth with leverage.

The step change in 2024 profitability is mechanical: in the fourth quarter of 2023 Iridium extended its satellites' estimated useful lives from 12.5 to 17.5 years, and annual depreciation fell by roughly $117 million. Revenue compounded steadily underneath — 5% in 2024, 5% in 2025 — driven by IoT subscriber growth and engineering services, while the constellation itself slowly depreciates away: net property and equipment fell every year until Aireon's $161.9 million of property reversed the slide in Q3.

Capital return has been the other constant: Iridium repurchased $247.0 million of stock in 2023, $407.7 million in 2024 and $186.5 million in 2025, shrinking the share count from 122.8 million to 104.9 million — then stopped entirely in 2026 with the merger pending. The dividend, by contrast, keeps rising: $0.15 paid in Q3, $0.16 planned from Q4, a 5.2% full-year increase. A company returning cash while its share count is frozen by a merger agreement is distributing the stub, not compounding it.

The Verdict: Bull vs. Bear​

Bull Case

• The merger consideration — $27 cash plus a collared stock component worth up to $27 more — puts a hard floor-plus-upside frame on the shares, approved by 99.6% of votes cast.
• Service revenue grew 13% and is 76% of the mix; Aireon adds a surveillance monopoly (the only space-based ADS-B system) to a subscription base that compounds.
• Subscribers grew 6% to 2.696 million with accelerating net adds (69,000 vs. 59,000), led by commercial IoT at 9% subscriber growth.
• The dividend rises to $0.16 in Q4, paying holders to wait for the mid-2027 close.
• EMSS extended through March 2027 at the same rate, de-risking the government renewal timeline into the merger window.

Bear Case

• Ex-gain pre-tax income was $5.2 million — the operating business earned almost nothing this quarter, and OEBITDA declined year over year.
• The $103.9 million gain is non-cash and non-recurring; the pro-forma accounts show Q3 net income of just $2.1 million as if Aireon had been owned all along.
• Net leverage sits at 4.2x trailing OEBITDA with $2.06 billion of net debt, and a seller note matures one year after the Aireon close.
• ARPU is falling in IoT (−4%) and broadband (−7%) while voice subscribers shrink — connections are growing faster than dollars, and management claims no pricing momentum.
• Transaction expenses ($21.3 million this quarter) run until the Rocket Lab deal closes, and any regulatory delay extends the bleed.

Our Take: Iridium's Q3 is a deal quarter wearing an earnings quarter's clothes. The operating business — flat OEBITDA, halved operating income, declining ARPU — does not support the headline, and the $103.9 million gain is a one-time accounting entry that the pro-forma statements quietly reduce to $2.1 million of real quarterly earnings power. But with 99.6% stockholder approval and a collared $27-plus consideration package, the operating story no longer sets the price — the merger does. Hold the stub for the close, watch the EMSS renewal as the one risk that could reprice it, and do not annualize $0.98 of quarterly EPS. The ledger, as always, shows exactly which dollars are real.
