IRDM vs LBTYA: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of October 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. IRDM and LBTYA share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined IRDM and LBTYA exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

Iridium Communications operates a constellation of 66 active low-earth-orbit satellites (plus in-orbit spares) that provides voice and data coverage across the entire planet, including the poles and oceans where terrestrial and geostationary networks fall short. Revenue comes from recurring satellite service (about 72% of the total), plus equipment sales, engineering, and support. Commercial IoT and a long-running U.S. government airtime contract are the backbone of the subscriber base, which reached roughly 2.56 million billable subscribers in early 2026. The U.S. government generated about 29% of 2025 revenue. Trailing twelve-month revenue reached about $884 million by mid-2026, and in October 2026 Altair Semiconductor said it would build Iridium's NTN Direct service into two of its cellular IoT chipsets.

Liberty Global is a Bermuda-based holding company that owns broadband, video, and mobile assets across Europe rather than running a single national network. Its structure spans three platforms the company calls Liberty Telecom, Liberty Growth, and Liberty Services. The largest pieces are a 50% stake in Virgin Media O2 (the UK's second-largest telecom operator, held as a joint venture with Telefonica) and the Benelux operations VodafoneZiggo and Telenet, which management is combining into a new entity called Ziggo Group. Ziggo Group named its leadership team and began operations in September 2026, bringing together Liberty Global's interests in VodafoneZiggo and Telenet, though some conditions of the transaction, including certain shareholder approvals, were still listed as open. Alongside these, Liberty Growth holds a venture portfolio of roughly 70 companies and funds valued near $3.4 billion, plus meaningful holding-company cash.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• IRDM drivers: Pending Rocket Lab acquisition; Recurring service revenue and IoT.
• LBTYA drivers: Sum-of-the-parts discount and spin-offs; Buybacks and a shrinking share count.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: The dominant risk is deal risk: a pending acquisition can be delayed, repriced, or fail regulatory review, and the stock could fall back toward standalone value if the transaction breaks. For LBTYA, liberty Global's European telecom assets carry substantial debt (about $9.3 billion on the consolidated balance sheet at mid-2026), and much of the value sits in joint ventures where Liberty does not have full control, which complicates capital decisions and payouts.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick IRDM if you believe its drivers more; LBTYA if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the IRDM and LBTYA guides.

IRDM. With a signed agreement and shareholder approval, IRDM is priced off the deal rather than earnings multiples: the trailing P/E near 50 and EV/EBITDA near 15 mostly reflect deal costs depressing profit and the takeover premium. At $44.36 the shares sat below the roughly $54 notional value cited at announcement, a spread that moves with Rocket Lab's share price and the market's view of timing and regulatory risk. Iridium no longer gives guidance, and its third-quarter report (expected around October 22, 2026) matters mainly as a check on the standalone business if the deal were to fail.

LBTYA. Liberty Global is best understood on an asset-value basis rather than through a simple earnings multiple, since much of its worth sits in joint ventures like Virgin Media O2 that are not fully consolidated in reported revenue, and reported earnings are negative and volatile. At about $8.03 on October 16, 2026 the shares trade near 0.56 times trailing sales and about 8.5 times EV/EBITDA, and the 13 covering analysts carry a mean target near $14.58. Figures are approximate and drawn from Yahoo Finance data as of October 2026; Q3 results are due November 3, 2026.

Headline figures (approximate, October 2026): IRDM shows deal terms $27/sh cash + Rocket Lab stock (collar); ~$54/sh notional at announcement, ~$8.0B enterprise value, expected close ~Mid-2027; shareholders approved September 2026, regulatory review pending, revenue (ttm) ~$884M; Q2 2026 ~$225M, up ~4% YoY, margins (ttm) Gross ~72%; operating ~15%; net ~11%; LBTYA shows consolidated revenue (ttm) ~$4.9 billion, q2 2026 revenue (yoy) ~$1.17 billion, down ~7.7%, ebitda (ttm) ~$1.14 billion, net income (ttm) ~-$3.0 billion.

IRDM and LBTYA are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined IRDM and LBTYA exposure against your real portfolio. It is not an investment adviser.
