Inpex Raises Full-Year Profit Guidance 45% Above Prior Midpoint on Ichthys Stability and Yen Weakness — JKM Supply Risk Minimal, Buy 1605 JP on Dips
Inpex's H1 2026 result delivered ¥263.1bn in profit attributable to owners of parent, up 17.7% year-on-year, on flat operating profit of ¥618.7bn (+0.3%) — a clean beat driven by lower income taxes (¥359.8bn vs ¥402.7bn in H1 2025) and a ¥158.37/$ average exchange rate that added ¥55.6bn to yen-denominated top line. The full-year guidance revision is the trade: Inpex now guides to ¥510bn in attributable profit, sitting 13% above the top of the prior ¥350–450bn range and 45.7% above the prior range midpoint. That's not a tweak — that's a structural reset of earnings expectations.
The crude oil volume line looks alarming at first read: overseas crude sales fell 22.8% to 55,170 thousand barrels in the half. But realised price tells the other side — overseas crude averaged US$79.51/bbl, up US$6.00 or 8.2% year-on-year. Revenue impact of the volume drop (-¥169.5bn) was more than half-offset by price (+¥49.2bn) and FX (+¥55.6bn). The volume decline is likely cargo-timing related, not a production miss; the company explicitly attributes the full-year guidance revision in part to "stable production of the Ichthys Project." Ichthys segment revenue came in at ¥215.8bn, +17.5%, with attributable profit of ¥173.0bn, +24.5% — this segment alone accounts for 65.7% of total group attributable profit. JKM prompt-month contracts should read this as a supply-neutral print; no unplanned outages are flagged, and overseas natural gas sales volumes of 208,903 million cf were only marginally lower (-0.6%) year-on-year.
The capex directional signal is important. Investing outflows hit ¥424.7bn in H1, up ¥60.4bn from the prior-year period, with the increase driven explicitly by "payments for acquisition of development and production assets." Oil and gas assets on the balance sheet expanded from ¥3,889.0bn at year-end 2025 to ¥4,039.4bn at June 30 — a ¥150bn step up in six months. That pace of asset accumulation, combined with operating cash generation of ¥553.8bn (+¥125.9bn YoY), suggests Inpex is self-funding an accelerating growth cycle. This is structurally supportive for the equity (1605 JP) and argues against crowding into any short positioning based on the revenue headline.
Inpex's revised H2 Brent assumption of US$75/bbl (Q3 at $80, Q4 at $70) is conservative against current forward curves and provides meaningful earnings upside optionality if Brent holds in the low-to-mid $80s. Each US$1/bbl move matters here: the prior-year H1 realised price of $73.51 vs the current $79.51 accounts for a meaningful portion of the earnings improvement. For Dubai/Oman spread traders, note that Inpex's realised crude price at $79.51/bbl ran approximately $8/bbl below H1 Brent actual of $87.6/bbl, consistent with a heavy sour crude basket — any Brent-Dubai widening scenario pressures realised netbacks at the margin.
On the FX side, the H2 yen assumption has been revised to ¥160/US$, compared to the prior guidance range of ¥152–154/$. The sensitivity is clear from the H1 narrative: ¥10 of yen depreciation contributed ¥55.6bn to revenue. USDJPY positioning matters directly to this name — yen strengthening toward ¥150 would shave roughly ¥55bn off the annualised revenue run-rate. The dividend revision signals confidence: interim dividend up to ¥56/share from ¥50 last year, with full-year guidance now at ¥112/share (ex-date effective September 1, 2026 for the interim payment).
The one soft patch is the domestic Japan segment, where revenue rose 6.4% to ¥112.6bn on higher domestic gas volumes (+9.7% to 1,284 million m3, or 47,905 million cf), but attributable profit collapsed 54.4% to ¥7.8bn due to cost of sales pressure. That's a structurally unattractive margin story worth monitoring but it represents a small fraction of group earnings and does not move the needle on the bullish setup at the group level.
What to Watch
- Brent holding above US$75/bbl through Q3 — Inpex's Q3 assumption is $80, and a sustained move below that erodes the H2 guidance cushion
- USDJPY — any appreciation through ¥155 challenges the ¥160 H2 FX assumption and creates a ~¥27bn revenue headwind per ¥1 move
- H2 crude oil cargo scheduling — whether the 22.8% H1 sales volume drop reverses in Q3/Q4 is the key volume recovery trigger for the full-year revenue line
- Ichthys maintenance calendar — no turnaround flagged in this report, but any announcement of planned downtime in Q4 would move JKM Q4/Q1 spreads and pressure the equity
- September 1 interim dividend payment confirmation and any commentary on a further full-year revision if Q3 Brent tracks above the $80 assumption
