Fitch Ratings has affirmed SierraCol Energy Limited's Long-Term Foreign and Local Currency Issuer Default Rating (IDR) at 'B+'.

The Rating Outlook is Stable.

In addition, Fitch has affirmed SierraCol Energy Andina, LLC's Long-Term senior unsecured ratings at 'B+'/'RR4'.

SierraCol's ratings reflect its small but stable low-cost production profile of roughly 43,000 boed in 2023, which is balanced across its two main assets, Cano Limon and La Cira Infantas. SierraCol has a long track record of operation in Colombia with solid production expected to average a gross 47,000 boed through the rating horizon, and 1P reserve life to average 7.0 years. The company has a strong leverage profile, which Fitch expects to remain at or below 2.0x through the rating horizon.

Despite strong operating metrics, the ratings remain constrained by the company's relatively small size and the low diversification of its oil fields.

Key Rating Drivers

Small Production Profile: SierraCol's ratings are constrained by its production size, projected to average 47,000 boed over the next four years, relative to the rating trigger of 75,000 boed. The company has a concentrated production profile split between its mains assets (CLM and LCI), representing 90% of total production, which it operates as a joint venture with Empresa Colombiana de Petroleos S.A. (Ecopetrol, BB+/Stable).

SierraCol produces high-quality crude with 94% of production having API gravity between 25-35. This gives it preferential treatment to sell locally to Ecopetrol, under contracts that guarantee pricing at a premium to the Vasconia discount.

Efficient Cost Producer: SierraCol is one of the lowest-cost producers in Latin America. Fitch estimates the company's half-cycle costs at USD26/boe in 2023 and full-cycle cost at USD44/boe in 2023. Fitch uses the half-cycle cost plus the three-year average FD&A for 1P of USD15/boe and a 15% of return on capital invested at USD2/boe in its calculation. SierraCol's USD76/bbl realized oil price is higher than peers due to the quality of its crude and its low transportation cost of USD1/boe as per its legacy contract with Ecopetrol, which compares favorably to most peers in Latin America.

Strong Leverage Profile: Fitch projects SierraCol's total debt/EBITDA ratio will be at or below 2.0x over the rating horizon. Fitch does not assume material addition or decreases in debt through the rating horizon. Fitch expects the company's debt to proven, developed, & producing (PDP) reserves of USD11/boe and total debt/1P of USD7.5/boe in 2024, and then decline to USD10/boe and USD7/boe in 2026, respectively. The latter assumes an average reserves replacement ratio of 102% for both PDP and 1P and an average reserve life of five and seven years, respectively, as the company deploys its 2024-2026 capex plan with an aggregate amount close to USD582 million.

Financial Flexibility: SierraCol is fully financed and should be able to cover all capex projects with internal cash flows. Under Fitch's price deck and production assumptions, cash flow from operations (CFO) should cover capex by more than 1.5x over the next four years. As of March 2024, the company's liquidity was adequate with cash and cash equivalents of USD111 million plus USD111 million in undrawn amounts from committed credit lines. The company's major debt maturity is its USD600 million bond which matures in June 2028.

The rating case is assuming dividends will be paid each year to its controlling shareholder, the Carlyle Group. However, Fitch does not expect dividends to materially exceed FCF.

Derivation Summary

SierraCol's credit and business profile is comparable with other small independent oil producers in Colombia. GeoPark Limited (B+/Negative), Frontera Energy Corporation (B/Stable), and Gran Tierra Energy Inc. (B/Stable) are all constrained to the 'B' category or below, given the inherent operational risk associated with small scale and low diversification of their oil and gas production.

SierraCol's production profile compares favorably with other 'B' rated oil exploration and production companies operating in Colombia. SierraCol's gross production averaged 43,000 boed in 2023, higher than Geopark's 37,000 boed, Gran Tierra's 32,600 boed, and Frontera's 41,000 boed. SierraCol's 1P reserve life of 7.0 years in 2023 is below Frontera's 7.3 years and Gran Tierra's 7.6 years.

SierraCol's strong capital structure is expected to have a gross leverage that will be at or below 2.0x over the rated horizon and debt/PDP of USD11/boe and total debt/1P of USD7/boe, which is lower than most peers in Latin America.

Key Assumptions

Fitch's Key Assumptions Within Our Rating Case for the Issuer Include

Fitch's price deck for Brent of $80 for 2024, $70 for 2025, and $65 for 2026 and 2027;

Average daily gross production of 47,000 boed from 2024 through 2027;

Reserve replacement ratio of 102% per annum over the rated horizon;

Lifting and transportation cost average of $16boe over the rated horizon;

SG&A cost average of $3.1boe over the rated horizon;

Hedging cost average of $0.5boe over the rated horizon;

Consolidated capex of $582 million from 2024 through 2026 averaging $194 million per year;

Minimum cash balance assumed at $100 million over the rated horizon;

Effective tax rate of 45% over the rated horizon.

Recovery Analysis

The recovery analysis assumes that SierraCol would be a going concern (GC) in bankruptcy and that it would be reorganized rather than liquidated.

GC Approach:

A 10% administrative claim.

The GC EBITDA is estimated at USD510 million. The GC EBITDA estimate reflects Fitch's view of a sustainable, post-reorganization EBITDA level upon which Fitch bases the valuation of SierraCol.

EV multiple of 4.0x.

With these assumptions, Fitch's waterfall generated recovery computation (WGRC) for the senior unsecured notes is in the 'RR3' band. However, according to Fitch's Country-Specific Treatment of Recovery Ratings Criteria, the Recovery Rating for corporate issuers in Colombia is capped at 'RR4'. The Recovery Rating for the senior secured notes is therefore 'RR4' with 50% recoveries in a hypothetical event of default.

RATING SENSITIVITIES

Factors That Could, Individually or Collectively, Lead to Positive Rating Action/Upgrade

Net production rising consistently to 75,000 boed on a sustained basis while maintaining a total debt to 1P reserves of USD5.00 barrel or below;

Reserve life is unaffected as a result of production increases, at approximately seven to eight years.

Factors That Could, Individually or Collectively, Lead to Negative Rating Action/Downgrade

Extraordinary dividend payments that exceed FCF and weaken liquidity;

Sustainable net production falls below 30,000 boed;

Reserve life declines to below 6.0 years on a sustained basis;

A significant deterioration of total debt/EBITDA to 3.0x or more.

Liquidity and Debt Structure

Adequate Liquidity: SierraCol's cash and cash equivalents balance as of March 2024 was USD111 million, plus USD111 million in undrawn amounts of committed credit lines. Total available liquidity covers interest expense of the next four years by 1.2x. Furthermore, the company is fully financed and Fitch projects that capex will be funded with internal cash flows with no material increases nor reductions in total debt. SierraCol has a favorable debt maturity profile, where USD20 million matures in the current year and its USD600 million matures in June 2028.

Issuer Profile

SierraCol Energy Limited is an independent oil producer created after Carlyle acquired Occidental Petroleum Corporation's operations in Colombia in December 2020. SierraCol is the third largest oil producer in Colombia with assets in the Llanos, Middle Magdalena, and Putumayo basins.

ESG Considerations

SierraCol's ESG Relevance Score for GHG Emissions & Air Quality is '4' due to the growing importance of the continued development and execution of the company's energy-transition strategy. This has a negative impact on the credit profile, and is relevant to the ratings in conjunction with other factors.

The highest level of ESG credit relevance is a score of '3', unless otherwise disclosed in this section. A score of '3' means ESG issues are credit-neutral or have only a minimal credit impact on the entity, either due to their nature or the way in which they are being managed by the entity. Fitch's ESG Relevance Scores are not inputs in the rating process; they are an observation on the relevance and materiality of ESG factors in the rating decision.
