The Take — Great rock, wrong price for the risk. Don't pay war-premium multiples for a peacetime asset; sell the volatility instead.
The operations are best-in-basin and that is not the debate. Q2-26: 156 kboe/d (+32% y/y), lifting cost $4.5/boe, 70% EBITDA margin, $805M adj. EBITDA, $491M FCF after the Equinor payment. Proved reserves 588 MMboe at YE-25 (+57%), organic replacement 260%, and a plan to 250 kboe/d by 2030. Vista executes — every target since 2021 has been raised, not cut.
But the stock is a Brent derivative wrapped in Argentina, and Brent is at a war print. Spot ~$105 reflects the Hormuz disruption; a year ago it was $64, and the forward curve is steeply backwardated. Our base deck follows the curve down ($104 Q4-26 → $88 2027 → $78 2028 → $70 mid-cycle, +2%/yr after 2030), applies a 14.1% WACC (Rf 5.2% + β 1.18 × 4.4% + 0.8 × 10% Argentina CRP), and lets Vista hit its 2030 volume — that's $59.64. The reverse DCF says today's $69.88 needs ~$74/bbl Brent forever (or a flat ~$81 from 2027), or a ~12.2% WACC — i.e. Argentina priced like an investment-grade sovereign 12 months before a presidential election with riesgo país back above 600bp.
The swing factor nobody models: capital intensity. Near-term, we take management's own capex ($1.8B in 2026, ~$5.6B through 2028). Long-run we assume ~$23k per new flowing boe/d against a 22% base decline, i.e. ~$1.4B/yr to hold 250 kboe/d. Management's 2030 FCF target (~$1.5B) implies ~$1.0–1.1B — at that intensity the stock is worth ~$88. That's the bull's best argument, and it requires shale efficiency gains that are still a promise. FCF has been negative two years running (2024 −$94M, 2025 −$659M) while EBITDA tripled; growth has eaten every dollar.
Argentina is the risk you aren't paid enough for at this price. Unconventional crude still pays export duty outside RIGI; Neuquén royalties are 12–18%; a 5-point fiscal tightening costs ~$13/share. Capital controls still restrict dividends (Vista pays none — growth plus cepo). The 2027 election is the binary: a Peronist return historically means domestic price caps (2022: "barril criollo") and higher retentions.
Call: No new longs at $70. Holders: trim above ~$72 and collar what you keep — Hormuz has inflated option IV, so a zero-cost collar (sell ~$85 call, buy ~$60 put, Jan-27) locks in most of the war-premium gain. Accumulate below ~$52 (≈ base −12%) or on a Brent reset to the $70s that drags the stock with it — that is where the asset becomes cheap. Income expression for non-holders: cash-secured puts at the $55 strike, 60–90 DTE, which gets you long at ~base value with the elevated vol premium as a cushion. Q3 results due late October.
Argentina sovereign / CRP — riesgo país rose from ~430bp (June) to >600bp (Sept) on 2027-election anxiety. Short: political reversal, BCRA reserve stress.
HIGH
Fiscal take & capital controls — export duties, provincial royalties, turnover tax; cepo limits dividends/remittances. Long: RIGI approvals (Bandurria Norte, Águila Mora filings). Short: duty re-imposition, domestic price caps.
MED
Leverage & capital intensity — net debt ~$3.1B, 1.41x (1.25x PF); still FCF-negative on a full-year 2025 basis after M&A. Equinor contingent consideration (oil-price-linked) grows with Brent.
Geology/operations — tier-1 acreage, $4.5/boe lifting, 14-yr P1 reserve life. This is the solid line.
What the "inventory" really is: 588 MMboe of P1 (40% PDP) plus a multi-decade drilling inventory valued only through the plateau. At $69.88 the market pays $17.5/boe of P1 against an SEC PV-10 of $11.2/boe — ~$4.1B of EV is for unbooked locations and for Brent staying above the SEC $64 deck.
Brent dominates, but capital intensity and Argentine fiscal take are each worth ±$10–13/share — the two inputs management controls least (fiscal) and markets underwrite most loosely (intensity).

Q4-26 stub at ~$104 in every cell. Green = >15% above price, red = >15% below. At today's WACC the stock is fairly priced at a flat ~$81 Brent. Spot ($105) holding for a decade is worth ~2x the price — that's the war-premium call option you're buying; at $65 or below you lose most of the equity.
History — EBITDA vs free cash flow ($M)
EBITDA grew ~6x since 2021; cumulative 5-yr FCF (2021–25) is −$438M and −$579M after SBC. 2025 includes ~$1.46B capex plus $842M of La Amarga Chica M&A in investing (not in FCF). TTM turns positive only on the Q2-26 oil spike.
Revenue/EBIT/EBITDA/OCF/capex/SBC from stockanalysis.com (IFRS, USD). Production 2021–23 and Brent averages approximate (company releases / market data); TTM production ≈ Q3-25–Q2-26 average. A growth company's averages understate run-rate, so normalization is done on unit economics, not on dollars.
What normalization says. 5-yr average EBITDA ≈ $38/boe at a ~$80 average Brent (2022 was depressed by Argentina's domestic price cap — the "barril criollo" — exactly the policy risk the CRP prices). Our cost stack reproduces Q2-26 ($56.7/boe at $89 realized) and gives ~$38/boe at $70 Brent, i.e. normalized 2027 EBITDA of ~$2.66B at mid-cycle vs ~$3.6B on the backwardated strip and management's ~$3.0B 2026 guide set at a higher deck. EBIT/boe will compress from the TTM as DD&A/boe rises with acquired-asset step-ups (TTM D&A $918M ≈ $18/boe).
Four lenses: P1 PV-10 NAV at SEC $64 / 10% → $34/share · P1 NAV re-risked at Argentine WACC (~20% haircut) → $21 · Production DCF, base (strip → $70) → $60 · Management capital intensity (~$18k/boe/d, 19% decline) at the same deck → $88. The price sits between the last two: you are paying for management's efficiency case and above-mid-cycle oil.

Unit model: realized oil = Brent − $5; gas ~$24/boe (13% of volume); royalties/duties 15% of revenue; cash opex+selling+G&A $12.1/boe in 2026 (+2.5%/yr). Capex = $23k × (base decline × prior production + growth) + ~$150M facilities/yr; decline glides 29% → 22%. Tax 35% on EBITDA − $17/boe DD&A. PV explicit 6,359 + PV terminal 3,839 = operating value 10,198. Terminal share 38% (well under the 70% flag). Plateau after-tax return on capex ~2.0x — high ROIC is real here; the problem is the discount rate and the deck, not returns.
