|---|---|---|
| Filing date (10-K) | March 14, 2025 | Identifies the reporting period and whether figures reflect the latest fiscal year. filing date |
| Amendment filed (10-K/A) | August 27, 2025 (10-K/A) | Shows restatements or material corrections; reassess prior conclusions if present. 10-K/A |
| Proved oil reserves | 2.6 million barrels (pro forma) | Key value driver for upstream valuation and PV-10 calculations. proved oil |
| Revenue (FY) | US$105.3 million | Top-line trend indicates production and price sensitivity. Revenue |
| Net income (FY) | US$12.2 million | Profitability metric after costs and impairments-watch non-operating items. Net income |

Practical checklist when reviewing Horizon Oil 10-K
- Confirm the exact entity: verify CIK or ticker to ensure you're reading the US SEC 10-K for the correct corporate entity. exact entity
- Compare reserves schedules to prior years and verify the company's commodity price assumptions used for PV-10. reserves schedules
- Read note disclosures for one-time items, impairments, and related-party transactions; check for 10-K/A footnotes. note disclosures
- Check the auditor's opinion and any "going concern" language or emphasis of matter. auditor's opinion
- Cross-reference legal proceedings and environmental provisions; if litigation exists, examine potential cash exposure and insurance coverage. legal proceedings
Statistics and historical context investors often miss
Year-over-year reserve changes typically drive the most meaningful valuation moves; for example, a 10% reserve downgrade in the proved developed category can cut PV-10 by roughly 8-12% depending on the price deck used. reserve downgrade
Historical filings show that midstream or transportation interruptions historically reduced realised prices by 3-7% in a given quarter for companies with concentrated sales routes; investors should check sales by counterparty tables. realised prices
Between 2018-2024, industry average finding & development (F&D) costs for smaller independent upstream companies ranged between US$10-$22 per barrel of oil equivalent; comparing Horizon's disclosed F&D to that band helps identify efficiency delta. finding & development
What to watch for in amendments and exhibits
10-K/A filings may correct material misstatements in financial statements or add new exhibits such as updated reserve engineering reports, tax opinions, or amended debt covenants; an amendment filed after the initial 10-K is a red flag that requires reading both versions side-by-side. material misstatements
Exhibits often contain loan agreements that reveal covenant triggers (e.g., minimum EBITDA, ratio tests) which, if breached, could accelerate debt-review exhibits carefully to assess default risk. loan agreements
Common red flags and how to quantify them
- Repeated 10-K/A filings within the same reporting cycle - indicates restatements or compliance issues; quantify impact by comparing pre- and post-restatement net income. restatements
- Large non-recurring impairment charges - check whether impairments are operational (production decline) or price-related; calculate impairment as % of total assets. impairment charges
- Rising decommissioning liabilities without matching cash-flow coverage - compute liability-to-CF ratio to assess funding risk. decommissioning liabilities
- Concentration of sales to one counterparty (>30%) - counterparty risk can lead to material revenue swings if the contract terminates. counterparty risk
Sample quote investors should look for in MD&A
"We continue to focus on lowering unit operating costs by $2.00 per boe and expect to realize a full-year reduction of 8% in 2026, subject to realized commodity prices and transportation availability."
This type of forward commentary gives management's operational targets and explicit sensitivity that can be stress-tested by investors. MD&A commentary
How to convert 10-K disclosures into a quick model
Extract these line items from the 10-K: production (boe), realized price per boe, operating cost per boe, capex, and decommissioning spend; build a sensitivity table with ±10% price and ±10% production to estimate free cash flow variability. quick model
Example investor action plan (quick)
- Download the latest 10-K and any 10-K/A; save both versions. download
- Extract reserves, production, and revenue by segment into a spreadsheet for trend analysis. extract reserves
- Run a sensitivity scenario on price and production; test covenant headroom against downside cases. sensitivity scenario
- Read legal proceedings and environmental notes to estimate contingent liabilities. contingent liabilities
- Check auditor language and search for subsequent events in 8-K filings. subsequent events
Data sources and verification steps
Primary verification should come from the SEC EDGAR filing for US filings and the company's investor-relations portal for ASX or home-market filings; tertiary sources include recognized market data providers and major financial outlets for press-release cross-checks. primary verification
Final practical tips
Build a short extraction template (one page) that lists: filing dates, proved reserves, realized price/boe, operating cost/boe, capex, impairment charges, and debt covenants-this makes cross-filing comparisons repeatable and reduces missed items. extraction template
When you find a 10-K/A, always compare the auditor's report and balance-sheet subtotals; a single changed line can materially alter ratios used in covenant tests. auditor's report
