Borr Drilling has spent the past eighteen months doing three things simultaneously: expanding its fleet from 24 rigs to 34, executing a landmark $2.035 billion refinancing that eliminates every near-term debt maturity, and operating those rigs at 99.4% technical utilization. In the same period, the share price has spent most of its time trading below $6.

At $4.80 per share — the base for all analysis in this issue — the market assigns Borr a market capitalization of approximately $1.48 billion against an enterprise value of roughly $3.8 billion. That enterprise value represents a business with 34 modern premium jack-up rigs, $1.17 billion in contracted backlog, and a management team that has grown the fleet 40% in two years through deals it financed without a single distressed equity raise.

This issue makes the case that the market has not yet priced two structural realities: first, that the debt wall that has suppressed multiple expansion for two years has now been fully resolved; and second, that the cycle for jack-up rigs is still in its early innings, with the best dayrate environment likely 12 to 24 months ahead of us — not behind us.

Before valuing a single share of BORR, investors need to understand why jack-up rigs occupy a structurally privileged position in the offshore drilling ecosystem — one that deepwater contractors like Transocean and Valaris (now merging into a $17 billion entity) simply cannot replicate.

A jack-up rig is a mobile drilling platform with legs that extend to the seabed in shallow water — typically less than 400 feet of water depth. The rig sits above the water surface on these legs, providing exceptional stability for the crew and drill string. Borr's entire fleet of modern Keppel and PPL-designed rigs operates in this space, targeting the world's most active shallow-water basins: the Middle East, Southeast Asia, the Gulf of Mexico, and West Africa.

A deepwater drillship, by contrast, is a floating vessel tethered via dynamic positioning systems to drill in water depths from 1,000 feet to 12,000 feet or more. Transocean's flagship units — the Deepwater Atlas, Deepwater Titan — are engineering marvels capable of drilling in some of the most hostile environments on earth. They are also enormously expensive to build ($800 million to $1 billion per unit), enormously expensive to operate ($500,000 per day at leading-edge rates), and require oil companies to commit to multi-year programmes to justify the economics.

The economics of shallow-water jack-up drilling are fundamentally more resilient at lower oil prices than deepwater:

The breakeven advantage matters enormously in the current macro environment. At $65–70 per barrel of oil — the range that has prevailed through much of 2025 and into 2026 — shallow-water jack-up programs remain highly profitable for operators. Many of the highest-value jack-up markets are NOC-dominated (Saudi Aramco, ADNOC, PEMEX, Pertamina) where production targets are driven as much by national revenue requirements as by short-term oil price economics. These customers do not cancel programs at $65 oil; they are mandated to produce.

Deepwater, while recovering, still faces a higher hurdle. The Transocean-Valaris merger — creating a 73-rig colossus focused on ultra-deepwater floaters — is a bet on long-duration contracted work at $450,000+ dayrates. That thesis has merit on a multi-year view, but it requires oil companies to make five-to-ten year financial commitments. It is a different, slower-cycle investment proposition.

Borr's positioning — 34 modern rigs, concentrated in the highest-activity shallow-water markets, with an average rig age well below the global fleet — gives it a structurally superior cost of production advantage that is invisible in headline dayrate comparisons.

Borr Drilling was founded in 2016 with a single thesis: buy modern jack-up rigs at distressed-cycle prices and operate them through the recovery. The company's founders — former Seadrill executives — identified that the 2015–2016 downturn had created an opportunity to acquire premium modern equipment at fractions of replacement cost.

From that foundation, Borr has built the youngest and most technically capable jack-up fleet among the pure-play public contractors. The fleet has grown in two steps: from 24 rigs to 29 via the Noble acquisition (completed January 2026), and from 29 to 34 via the Fontis/Paratus 50-50 Mexican JV (announced March 2026, expected to close Q3 2026). As of Q1 2026, the consolidated fleet stands at 29 wholly-owned rigs with the five JV rigs pending close — with management already referring to a 34-rig fleet in anticipation of that closing.

The strategic logic has always been fleet scale plus contract coverage. With 34 rigs at full fleet (once the Fontis JV closes in Q3 2026), Borr can credibly bid on multi-rig national programs that require scale, consistency, and track record. Saudi Aramco, ADNOC, and Pertamina award long-duration work to contractors they trust to deliver across large fleets simultaneously. Single-rig operators cannot bid for this work. Borr, at 34 rigs, is one of the largest premium jack-up contractors among public pure-plays globally, and increasingly wins on that basis.

The Q1 headline numbers look soft on first reading — EBITDA was dented by an $8.4 million credit loss provision and the delayed start of the Odin rig. Strip those items out and the underlying operational performance is strong. 99.4% technical utilization across a 34-rig fleet is exceptional; it means effectively not a single rig was unavailable for planned maintenance or unplanned failure during the quarter. That statistic becomes more impressive when you understand that five of those rigs — the Noble acquisition — had only just been integrated into the operating fleet.

The jump from 22 rigs in mid-2024 to 34 rigs entering 2026 was not organic — it was executed through two strategically distinct transactions that deserve analysis in their own right. 2 outright purchases in 2025 got the count to 24.

In late 2025, Borr completed the acquisition of five premium jack-up rigs from Noble Corporation — the same Noble that was simultaneously being absorbed into the Transocean-Valaris deepwater combination. Noble was exiting the jack-up segment entirely to focus on deepwater; Borr was the natural buyer.

The five rigs — all modern premium units — came with existing contracts and operator relationships in the Middle East and Southeast Asia, two of Borr's core markets. The seller's credit structure ($150M, variable rate, due 2027) allowed Borr to fund the acquisition without a large upfront cash outlay, preserving liquidity for operations. These five rigs are now fully integrated into the operational fleet and are included in the 71% H2 2026 coverage figure. They are reflected in every line of the FCF model in this issue.

In Q1 2026, Borr announced a 50-50 joint venture with Mexican partners (Fontis and BC Ventures) to acquire five Paratus Energy Services rigs operating primarily in Mexico under contracts with Pemex, the Mexican national oil company. The total transaction value was approximately $287 million, with Borr's $25 million cash outlay funded via a non-recourse seller credit — meaning Borr acquired a 50% economic interest in five additional rigs for $25 million of its own cash.

The JV structure is important and requires separate treatment from the wholly-owned fleet:

When management refers to a 34-rig fleet, they mean the 29 wholly-owned rigs plus the five Fontis/Paratus JV rigs once that acquisition closes in Q3 2026. The progression is: 24 rigs (pre-Noble) → 29 rigs (Noble acquisition, January 2026) → 34 rigs (Fontis JV, expected Q3 2026). The FCF model in this issue uses 34 rigs as the full operating fleet from 2027 onwards, with a conservative 29-rig assumption for much of 2026 pending the JV close. This makes the model slightly conservative on 2026 but appropriately reflective of the timing.

The most important thing that has happened to BORR's investment thesis in 2026 has nothing to do with dayrates. It is the complete elimination of near-term refinancing risk through one of the most decisive balance sheet restructurings in the offshore drilling sector's recent history.

To understand why this matters, you need to understand what BORR's debt stack looked like entering 2026 — and what it looks like today.

This capital structure had one critical problem: $1.18 billion of 10% notes due in 2028 created a refinancing cliff that the market was pricing as an existential risk. At every dayrate scenario below $150,000 per day, BORR's ability to service and eventually retire this debt was questionable. The stock traded accordingly — compressed to a valuation that reflected the debt risk, not the operational quality of the fleet.

In April 2026, Borr executed the first step: a $300 million offering of new senior unsecured convertible notes due 2033 at 3.5% interest — less than one-third the coupon of the notes they were replacing. The proceeds were used to repurchase and cancel $195.2 million of the 2028 convertible bonds, extending that maturity by five years and reducing the annual interest burden on that tranche by approximately $4 million.

On 27 May 2026, Borr priced the transaction that resolves the structural risk entirely. The company issued $2.035 billion of senior secured notes — upsized by $435 million from the originally contemplated $1.6 billion — in two tranches:

The proceeds were used in full to retire the 10.000% 2028 notes and the 10.375% 2030 notes — the two instruments that constituted the debt wall. Settlement occurred on or around 10 June 2026.

Three structural improvements that the market has not yet fully valued:

The central question for any BORR investment is deceptively simple: at what dayrate environment does this business generate enough free cash flow to justify a materially higher share price? The answer requires modelling four variables that interact non-linearly: consolidated fleet size, average contracted dayrate, interest burden on the parent balance sheet, and — critically — the separate contribution of the Fontis JV.

The 29 wholly-owned rigs (including the five Noble rigs) are consolidated into Borr's revenue and EBITDA in full. The five Fontis JV rigs are not — they are a 50-50 joint venture accounted for under the equity method, meaning Borr recognizes only its 50% share of JV net income as a single line below EBITDA. The JV's $237 million of non-recourse seller credit debt sits at the JV entity level and is not on Borr's consolidated balance sheet — but it must be serviced before any cash reaches Borr's equity earnings line.

Most published models treat BORR as a simple 34-rig business. That overstates consolidated revenue by approximately 17% and understates the complexity of the JV earnings stream. The model below gets this right.

The 2026 consolidated utilisation of 88% is calibrated directly from Q1 actuals — 29 rigs, 97% economic utilisation in Q1, but with the Odin delayed start and two rigs transitioning between contracts expected to weigh on Q2. The H2 improvement is supported by 65% H2 coverage already contracted at $137K average dayrate, rising as uncontracted days fill. Parent interest of $192M reflects the new notes ($180M) plus the April 2026 convertibles ($10.5M) plus residual 2028 converts ($1.2M).

Mexico context: the JV close is expected Q3 2026, so 2026 reflects approximately half-year contribution. Pemex is a slower-paying customer; the 85% utilization assumption in 2026 includes a conservatism buffer for payment delays and potential idle time during regulatory approvals. From 2027 the five rigs are assumed fully operational at 90%+ utilization.

The table below presents the corrected five-year FCF model at six dayrate scenarios. The consolidated 29-rig revenue and the 50% JV equity earnings contribution are shown separately so the analytical split is transparent. The same dayrate assumption is applied to both blocks for simplicity; in practice JV rigs in Mexico may price differently to the global fleet.

Several observations from the model:

The Q1 2026 investor presentation shows '$144M debt amortization per annum' prominently on the liquidity slide. This figure was correct for the old capital structure — the 10% 2028 notes and 10.375% 2030 notes included scheduled amortization payments. The May 2026 refinancing replaced both instruments entirely with bullet notes maturing in 2032 and 2034. Bullet notes have no scheduled amortization — the principal is repaid in full at maturity. The $144M annual cash outflow is gone. This single structural change adds $144M to annual FCF, equivalent to $0.46 per share per year, or $2.32 per share cumulatively over five years.

At $4.80 per share, that $2.32 cumulative FCF benefit represents 48% of the current market capitalization — created purely by the refinancing, before a single dayrate improvement occurs.

'Torque' in an investment context means sensitivity to positive change — the leverage embedded in the business model such that a given improvement in underlying conditions produces an outsized improvement in shareholder value. BORR has exceptional torque for three structural reasons that most comparable companies cannot replicate.

Operating leverage in jack-up drilling is extreme. Rig operating costs (crew, maintenance, insurance, logistics) are largely fixed regardless of dayrate. When dayrates increase by $10,000 per day, the overwhelming majority of that increment falls directly to EBITDA.

Not all jack-up rigs command the same dayrates. Premium modern rigs — the kind Borr operates, designed to 350-foot water depth with advanced well control systems and high variable deck loads — consistently command a 15–25% premium over older, legacy units.

This is the most underappreciated structural difference between BORR and its closest peers. The new 2032 and 2034 bullet notes require no scheduled principal repayment through 2031. Valaris (pre-merger) and Transocean carry amortising credit facilities and term loans that require meaningful annual principal payments — capital that reduces FCF available to equity holders.

The EV/EBITDA comparison is even more striking on the corrected numbers. At $140,000/day rates, consensus EBITDA of approximately $440M (29 consolidated rigs, per Q1 management commentary) implies Borr trades at approximately 3.8x EBITDA on an enterprise value of ~$3.8 billion — compared to 8–10x for the Transocean-Valaris deepwater entity. The JV equity earnings add a further ~$39M that does not flow through the EBITDA line at all, making the effective economic multiple even lower.

There are four risks that warrant real weight.

The Aramco suspension is both the largest near-term risk and the largest near-term catalyst. BORR has meaningful fleet exposure to the Middle East; if Aramco's reduced program is sustained through 2027, the H2 2026 and FY2027 FCF scenarios shift materially toward the lower columns in the sensitivity table. The company itself acknowledged Middle East uncertainty on the Q1 2026 call while expressing confidence about 2027 and 2028 prospects.

At $120,000/day, BORR generates negative FCF. This is not an existential crisis — the company has $480M of total liquidity and no debt maturities of consequence before 2027 — but it means the share price is highly sensitive to sustained low dayrates. The margin for error below $130,000/day is limited.

The five-rig Paratus acquisition via a 50-50 JV with Mexican partners adds scale but also complexity. Mexico's NOC (Pemex) has historically been a difficult customer — payment terms are often extended and contract renegotiations are not uncommon. The JV structure limits BORR's downside but also caps upside if the Mexican market softens.

The $300 million of 2033 convertible notes convert into shares at $8.00 per share — approximately 37.5 million additional shares. If the stock re-rates to $8–$10, conversion becomes likely, adding approximately 12% to the share count. Investors buying below the conversion price are effectively protected; those buying above should factor this into their per-share analysis.

Borr Drilling at $4.80 per share is a business with 29 wholly-owned premium jack-up rigs plus a 50% economic interest in five more via a Mexican JV — a contract backlog of $1.17 billion, near-zero refinancing risk through 2031, and a management team that has grown the fleet 40% in two years while maintaining 99%+ technical utilization. The primary reason the stock has traded at a compressed multiple is no longer present.

The debt wall is gone. The $144M of annual amortization payments that existed under the old structure have been eliminated by the bullet note refinancing. The fleet is scaled. The cycle is early.

At current dayrates on the corrected model — properly splitting the 29 consolidated rigs from the 50% JV equity earnings — BORR generates a 25.6% FCF yield at $140K/day on the base price. That is not a bull case number. It is current rates on the existing contracted fleet, with the amortisation drag correctly removed. At $160,000/day — rates last seen in 2023 — the FCF yield exceeds 37% and the 5-year cumulative FCF of $3.05 billion is more than twice the current market capitalisation.

The market is pricing BORR as though the refinancing risk still exists and as though the $144M annual amortisation is still running. Both of those assumptions were true six months ago. Neither is true today. The bullet note structure means no principal is due until 2032.

For a business generating $105M of incremental annual FCF per $10,000 of dayrate improvement across its full economic fleet — and that has just eliminated the one structural impediment to multiple expansion — the asymmetry from $4.80 is compelling. It does not need perfection. It needs rates to recover by $15,000–$20,000 and the market to process what the refinancing actually did to the capital structure.

Both of those conditions are either already in place or in progress.
