How to Value STMP Stock: NAV Methodology and 2026 Scenario Analysis

Valuing junior oil exploration stocks like Stamper Oil & Gas Corp involves unique challenges. Traditional valuation metrics, such as price-to-earnings (P/E) ratios, do not apply to pre-revenue companies. These companies typically invest heavily in exploration and development without immediate returns. Instead, investors focus on potential future cash flows derived from successful discoveries.

The primary methodology used for valuing these companies is Net Asset Value (NAV). NAV provides a framework for estimating the potential value of a company's assets, specifically its exploration licenses. This approach considers the estimated recoverable resources, the costs associated with extraction, and the likelihood of successful exploration. For Stamper, the NAV is further divided into risked and unrisked categories, reflecting different scenarios of success in exploration.

Stamper Oil & Gas Corp's valuation can be broken down into risked and unrisked NAV. The risked NAV of approximately $255 million reflects a probability-weighted assessment of the company's exploration potential, taking into account the likelihood of success for each of its Petroleum Exploration Licenses (PELs). In contrast, the unrisked NAV, estimated at over $1.5 billion, assumes that all exploration efforts are successful, which is a more optimistic scenario.

To arrive at these figures, investors must assign probability weights to each PEL. For example, PEL 107, with a 32.9% working interest, is considered the highest-value block due to its proximity to significant discoveries made by supermajors such as TotalEnergies and Shell. The carried interest in other blocks like PEL 98, PEL 102, and PEL 106, which require no upfront costs from Stamper, adds further value. These blocks represent option value, as they could yield significant returns if exploration is successful.

Assigning probability weights to each of Stamper's PELs is crucial for accurately estimating risked NAV. Each PEL has a different level of geological certainty and proximity to existing discoveries, which influences the likelihood of success. For instance, PEL 107's adjacent discoveries by TotalEnergies and Shell enhance its perceived value, leading to a higher probability weight.

Conversely, PELs with less geological certainty or further from successful wells may receive lower probability weights. For example, while PEL 98, PEL 102, and PEL 106 carry no exploration costs for Stamper, their potential success is less certain compared to PEL 107. By carefully analyzing these factors, investors can create a more nuanced valuation that reflects the risks and opportunities associated with each license.

To understand the potential future value of STMP stock, it is essential to consider various valuation scenarios: base case, bull case, and bear case. The base case assumes a successful farm-down of PEL 107, where Stamper retains a carried interest and benefits from the capital and expertise of a supermajor. This scenario could lead to significant cash inflows, enhancing the company's valuation.

In the bull case, a discovery by Chevron in the Walvis Basin could substantially increase the value of adjacent PELs 98 and 106. This scenario would likely lead to a re-rating of STMP stock, similar to the precedent set by Sintana Energy, which saw its market cap rise from approximately $27 million to over $200 million following nearby supermajor discoveries.

Conversely, the bear case assumes no near-term farm-out or successful discoveries, which would likely keep STMP's valuation stagnant at its current market cap of around $10 million. Understanding these scenarios helps investors gauge the potential upside and downside risks associated with their investment in Stamper.

The recent history of Sintana Energy serves as a valuable precedent for investors considering STMP stock. Sintana's market cap increased dramatically from approximately $27 million to over $200 million as nearby supermajors made significant discoveries. This re-rating was driven by the de-risking of Sintana's acreage, which became more valuable as exploration success in the region was confirmed.

For STMP, the potential for similar re-rating exists, particularly with its strategic positioning in the Orange and Walvis Basins. As supermajors like TotalEnergies and Chevron continue to explore and develop adjacent blocks, the value of Stamper's exploration licenses could increase significantly. Investors should monitor developments closely, as successful discoveries in the region could trigger a similar valuation shift for STMP.
