AI Analysis · Q1 2026

Oak Hill Advisors' Q1 2026 13F is a $878M, 12-position fund with one of the most concentrated energy-service structures in this batch — Valaris Ltd ($469.8M, 53.5% of AUM, +$228.3M, +94.5% shares) and Expro Group Holdings ($208.0M, 23.7%, +$45.9M but -1.6% shares — the value 'increase' reflects market appreciation) together account for 77.2% of the portfolio, making this effectively a leveraged offshore-oilfield-services-and-drilling play wrapped in a 13F-detectable institutional wrapper. The quarter's headline trade is the $228.3M increase in Valaris — a 94.5% share raise that brings the position from 39.4% to 53.5% of AUM and is the single largest increase in this filer's history, signaling either a new capital infusion specifically directed at Valaris or a dramatic re-assessment of the offshore-drilling recovery cycle. The offset was a rotation within the credit sleeve: FS KKR Capital ($91.4M, +$52.7M, +243.9% shares — from a tiny 2.6M-share base to 9.0M shares) was dramatically increased, while FSSL (FS Specialty Lending, $34.6M, -$4.5M, -1.6% shares — value decline, not a share reduction), XJQCX (Nuveen Credit Strategies, $16.1M, -$0.5M, flat shares), HYT (BlackRock Corporate High Yield, $9.1M, +$1.2M, +20.0%), DSU (BlackRock Debt Strategies, $5.6M, -$0.4M, -5.4%), and XEVVX (Eaton Vance Limited Duration, $3.7M, -$0.2M, -5.4%) were all adjusted at the margin. The fund sold its Cable One bond position ($14.4M, a 2026 maturity that presumably paid off at par in Q1), liquidated its position in Emergent Biosolutions (-$35.4M, -69.2% shares — from $44.7M to $9.2M, a distressed biopharma cleanup), and opened tiny exploratory positions in Sabre ($14.8M, travel technology), iHeartMedia ($14.3M, audio media), and Claritev ($1.5M, a spinoff of a prior holding). At a 77.50 whaleScore on $878M, this is best read as a private-credit-and-energy shop that has decided its highest-conviction 2026 theme is the offshore-drilling recovery (Valaris at 54%) and is using its credit-sleeve expertise to layer in BDC-and-distressed-debt exposure (FSK +244%) alongside the energy core.

The Valaris increase is the most striking trade in the filing and one of the largest single-position increases across this entire batch. Valaris grew from $241.5M (39.4% of AUM in Q4, when AUM was $612.8M) to $469.8M (53.5% in Q1, when AUM is $878M) — a $228.3M and 4,791,979 share increase (+94.5%). The AUM growth from $612.8M to $878M ($265.2M new capital) explains roughly 86% of the Valaris increase on a proportional basis (if the manager allocated new capital in proportion to existing weights, Valaris would have grown by ~$104M, not $228M); the remaining $124M is an active reallocation FROM other positions INTO Valaris. This is a deliberate decision to concentrate the portfolio further in the offshore-drilling thesis. Valaris is an offshore drilling contractor that operates jackups, semisubmersibles, and drillships in the Gulf of Mexico, North Sea, and international markets — a business that benefits from the 2024-2026 deepwater E&P capex cycle driven by supermajor oil companies replacing aging production and developing new fields. The manager's 53.5% weight is a high-conviction bet that offshore drilling rates will remain elevated through 2027-2028 as Permian land opportunities tighten and supermajors turn back to deepwater.

The Expro position provides complementary but distinct exposure. Expro Group ($208.0M, 23.7%, 11.9M shares) — a well-services-and-formation-evaluation company that provides wireline logging, perforating, and coiled-tubing services — was essentially flat in share terms (-1.6%) but rose $45.9M in value, which is mark-to-market appreciation rather than an active add. Expro's business is one layer closer to the reservoir than Valaris's rig-based drilling: Expro's services are required on every well regardless of who owns the rig, which gives it a more recurring, less cyclical revenue stream. The pairing of Valaris and Expro creates a full-stack offshore-energy book: Valaris captures the drilling-cycle upside, Expro captures the well-services floor.
