Not investment advice. I’m long. Do your own work. All figures from SEC filings, the May 5, 2026 CEO Letter to Shareholders (8-K), and public market data.

The Company
Momentus is a U.S. commercial space company providing in-space transportation, hosted payloads, and in-orbit services via its Vigoride Orbital Service Vehicle. HQ San Jose. CEO John Rood, former U.S. DoD Under Secretary of Defense for Policy.
2026 guidance and balance sheet (per May 5, 2026 Shareholder Letter, 8-K)

2026 revenue forecast: $10.0M, a 9x increase over $1.1M in 2025, driven by milestone-based contracts with NASA and DoD

Cash on hand: $26.2M as of April 23, 2026 (up from $12.8M at YE 2025)

Estimated runway: at least 12 months per management

Debt: zero — remaining $1.35M convertible debt retired April 17, 2026

Vigoride 8 mission already sold out

Capital structure

Shares outstanding: 5,730,006 per the March 27, 2026 10-K + 1,333,333 issued in the April 16 private placement

Reference share base in Citadel’s 13G: 6,364,291

Market cap: ~$33M at last close
ATM facility: ~$4.2M remaining capacity under the active S-3 prospectus supplement

Share count up ~486% over the past 12 months (significant historical dilution — state plainly)
Short interest

1.6M shares short, 27.1% of float

Up 406.7% from the prior reporting period, up 535.8% over 12 months

Institutional holders

Citadel Advisors LLC and affiliated entities (Citadel Advisors Holdings LP, Citadel GP LLC), along with Kenneth Griffin, disclosed a 9.97% passive stake via Schedule 13G filed April 22, 2026 — 634,285 shares beneficially owned, calculated against a 6,364,291 share base that includes 184,285 warrant-issuable shares. The position is capped at 9.99% by warrant exercise terms. Citadel Securities LLC and other Citadel affiliates are co-filers on the joint filing agreement

Beyond Citadel, institutional ownership is thin…

The April 16 $5M private placement was sold to a single new “fundamental institutional investor” at $3.75/share

Operational execution

Vigoride 7 launched to orbit March 30, 2026 on SpaceX Transporter-16. Hosting 10 payloads.

DARPA contract: ~$4.2M. SpaceWERX contract: ~$1.9M.

Vigoride 8 Preliminary Design Review complete. Two NASA contracts (Spaceworks COSMIC payload, NASA-commissioned Juno RDRE). CDR targeted late May 2026, launch early 2027. Manifest sold out.

May 5 letter from CEO Rood emphasizes contract wins, revenue growth, debt retirement, balance sheet strengthening.

Bull case

Management has put a number on the page: $10M guided revenue, 9x growth, anchored in milestone-based NASA and DoD contracts — not speculative bookings.

Cash position of $26.2M against a ~$33M market cap means a meaningful chunk of the cap is backed by cash. EV is compressed.

Debt-free balance sheet after convertible retirement reduces dilution pressure relative to the prior 12 months.

Vigoride hardware is flying, Vigoride 8 is sold out

Citadel’s 9.97% passive stake on a microcap is notable. So is a new fundamental institutional investor anchoring at $3.75 in April.

Small float (sub-7M) and rising short interest (27% of float) on a name with guided revenue inflection and federal customer concentration is a structurally unusual setup.

CEO is a credible operator with DoD background — relevant given customer mix.

Bear case
$10M is a forecast, not a result. Milestone-based revenue can slip. If milestones miss, the guide misses.

TTM operating loss was -$27.3M against $1.1M revenue. Even if revenue hits $10M, the operating gap is still wide. Cash burn likely continues.

Historical dilution is severe (share count +486% in 12 months). ATM facility is still active with $4.2M remaining capacity.

A higher share price increases what the company can sell under the ATM. Holders eat that dilution if it’s used.

Commercial space is competitive and capital-intensive. Path to gross-margin breakeven and operating breakeven is unclear from public disclosures.

Microcap volatility cuts both ways

27% short interest reflects genuine bearish conviction

Why I’m posting

I find the combination interesting: a commercial space company with a genuine story — trying to fill the last-mile gap by helping customers reach their final orbital destination — trading at a ~$35M valuation, with management guiding a 9x revenue inflection anchored in milestone-based federal contracts, a debt-free balance sheet, and 12+ months of runway. The bear case on dilution and execution is real, and I’m not waving it off. This is a microcap speculation.
