Grindr Inc [GRND] — Trade Construction & Risk Management

The memo issues no position verdict. What follows is the construction analysis a book would need if it decided to take the name. Nothing here is a recommendation to trade.

---

1. Underlying liquidity — verified first

PASS. At 15% of consolidated ADV a $3m position builds in one day.

Feed warning, same as OMDA: IEX-only is 18.3x below the consolidated tape. Any liquidity test built on feed=iex — which is what assets/own_multiple_history.py requests — understates by more than an order of magnitude.

Float caveat that ADV does not capture. Grindr is a controlled company: G. Raymond Zage III held >50% as of 2025-09-19, and the company has since retired a further ~12.5% of the share count without him participating, so his stake is now mechanically higher. The tradeable float is materially smaller than the 177.7m share count implies, and the exact figure is not disclosed in the sources reviewed. ADV of $22m is the observed reality and it is sufficient; but a forced exit into a stressed tape has a thinner book behind it than the market cap suggests.

2. Options chain — pulled first, and it fails

A vehicle that cannot be filled is not a vehicle. Full chain pulled from paper-api.alpaca.markets/v2/options/contracts and quoted via data.alpaca.markets/v1beta1/options/snapshots before any structure was considered.

Universe: 90 active contracts, expiries 2026-09-18 · 2026-11-20 · 2027-01-15 · 2027-02-19, strikes $12–$26. Total open interest across the entire window: 4,547 contracts.

For scale: OMDA, at 41% of Grindr's market cap, carries 15,270 contracts of open interest — 3.4x more.

Every contract with OI ≥ 50, with live quotes (2026-07-28):

Verdict on options: effectively uninvestable, and this is the HCA failure mode

criteria.md, Liquidity Criteria: "On HCA the maximum open interest across an entire March-2027 chain was 18 contracts; the default defined-risk spread was uninvestable at any size and nothing tested for it."

Grindr is a milder version of the same thing, and it fails for four separate reasons:

1. Three of four expiries are dead. September-2026 has 44 contracts of total OI. February-2027 has 13. November-2026 has 452, of which 200 sit in a single put that has no bid at all.
2. Only one expiry is usable (January-2027), which forecloses calendars, diagonals and any structure requiring two live expiries.
3. The put side does not function. Three puts carry OI ≥ 50; their quoted spreads are 169%, 187% and no-bid. Protective puts, put spreads, collars and risk-reversals are all unfillable at any size.
4. Even on the call side, quotes are unreliable. The $16 January call — one strike from at-the-money — quotes 1.42 / 4.02, a 95% spread, while the $17 call quotes 12% wide. Adjacent strikes with a 8x difference in relative spread is a sign of stale or one-sided quoting, not a functioning market.

If any options structure were forced, the only defensible pair is a January-2027 $17 / $20 call spread (GRND270115C00017000 / GRND270115C00020000, OI 642 / 840, spreads 12% / 21% — the two tightest quotes in the chain), net debit ≈ $2.49 / $3.36 mid $1.07, max value $3.00. But note the $17 strike is essentially at the money and the 12-month target of $23.72 sits above the $20 short strike, so the spread caps out well below the thesis. That is a poor expression of this particular view.

Implied vs realised volatility. Chain IV clusters at 47–57% against realised 252-day volatility of 50.3%. Options are roughly fairly priced — unlike OMDA, there is no vol premium to sell. So there is no volatility argument for options either.

Conclusion: the vehicle must be common stock. Options fail the Liquidity Criteria on the put side outright and offer neither a fill advantage nor a volatility edge on the call side.

3. Position sizing

• Realised vol 50.3% — high, though below OMDA's 57.0%. Inverse-vol sizing assigns roughly 0.42x the unit weight of a 21%-vol large cap.
• A leverage overlay is warranted and inverse-vol sizing does not capture it. Grindr carries $391.1m of debt against $839 thousand of book equity. Equity volatility understates the true left-tail because the observed 50.3% was realised during a period of rising revenue; the same operating variance transmits to equity with far more amplification on the way down. Size below what inverse-vol alone would suggest.
• A control overlay is warranted. A >50% holder whose standstill expires ~2027-08-26 both floors and caps the outcome. Positions whose thesis depends on multi-year compounding are structurally exposed to a take-out at a price the controlling holder chooses to offer.
• Market cap $2.95bn (mid bucket); liquidity does not bind.

4. Entry, exit, and thesis invalidation

Entry. 12-1 momentum is −19.8% — a weak cross-sectional reading. Spot $16.62 sits at the 77th percentile of the 52-week range but the 37th percentile of the name's own EV/Sales history. That combination — high in the price range, low in the multiple range — is what revenue growth outrunning the share price looks like, and it is the constructive part of the setup.

The company itself was buying at $11.63 (ASR inception, Q1'26) and $12.11 (prepaid put settlement). Any entry at $16.62 is 43% above where management last put the balance sheet to work. That is not a disqualifier, but it should be stated plainly rather than glossed.

Target. $23.72, +42.7% — FY2027 revenue +20%, multiple at the 50th percentile (7.60x) of the name's own 868-day post-de-SPAC EV/Sales history, from the current 37th percentile. Range across the p25 → p75 multiple band: $20.20 → $27.80.

Named thesis invalidation triggers — each observable in a filing or press release:

1. Advertising revenue growth falls below +25% YoY (from +68.1%). Advertising is carrying roughly 12 points of the 38.3% headline; it is the marginal driver and the first thing to break.
2. Average Paying Users grow less than +10% YoY (from +18.6%). Volume is the majority of subscription growth; if it stalls, the remaining growth is price, and price alone does not support 6.98x sales.
3. FY2026 revenue guidance is not raised again, or FY2027 initial guidance comes below +15%. Grindr guides in "at least" language and raised on 2026-05-07; a flat guide is a signal in this company's idiom.
4. Total debt rises above ~$450m, or the revolver is drawn to fund further buyback. Leverage is currently comfortable (2.7x EBIT, 6.4x interest cover); a further step-up changes the risk profile materially given book equity is $839k.
5. A goodwill impairment of any size. $275.7m of goodwill against $839k of equity — any impairment takes book equity negative. Tested annually in Q4.
6. A going-private proposal after the standstill expires ~2027-08-26. Terminates the thesis on someone else's terms.
7. ASR or FRT settling materially adversely. Both settle on VWAP by Q3 2026, and the FRT contains a bifurcated derivative not indexed to Grindr's own stock. Watch the Q2'26 and Q3'26 10-Qs for the final share counts.

Stop discipline. A thesis stop on triggers 1–3, not a price stop. The downside case (GRND_Research.md §10) is −23% to −47% to $12.84 / $8.85, both inside the name's own realised range (52-week low $9.86). It is a de-rating case: 2.7x EBIT of leverage and 6.4x interest cover mean this is not a solvency story, and the near-zero book equity is a buyback-accounting artefact rather than a distress signal.

5. Vehicle recommendation logic

No trade is recommended. The construction above exists so the book can act without re-deriving the fillability constraints, and so that the two overlays inverse-vol sizing does not capture — leverage and control — are applied deliberately rather than forgotten.
