RPRX vs TPL: Which Is the Better Buy in 2026?
Last updated October 2026
Short answer
RPRX is the larger of the two ($33.36B market cap): the incumbent the market prices for continued execution (10.07x forward earnings, beta 0.43). TPL is the smaller challenger ($23.24B), cheaper on forward earnings (4.61x): more room to run, but more to prove. The real question is which set of drivers you believe, and whether owning one (or both) leaves you over-concentrated.
RPRX vs TPL: the tie-breaker metrics
Same yardstick, side by side (as of October 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.
| Metric | RPRX | TPL | What it tells you |
|---|---|---|---|
| Market cap | $33.36B | $23.24B | Size. The larger name is the incumbent; the smaller has more room to grow and more to prove. |
| Forward P/E | 10.07 | 4.61 | Valuation on next year's expected earnings, the same yardstick for both. Lower is cheaper for that growth; higher means the market is paying up. |
| Trailing P/E | 31.04 | 42.98 | Valuation on the last 12 months. A big drop from trailing to forward means the market expects earnings to jump, so more growth is already in the price. |
| Beta | 0.43 | 0.62 | Volatility vs the market. Above 1 swings harder than the index; below 1 is steadier. Higher beta means bigger drawdowns to hold through. |
| Price vs 52-week range | 77% of range | 24% of range | Where today's price sits between the 52-week low and high. Near the high is momentum with less margin of safety; near the low is out of favor or a discount, depending on why. |
| Price / book | 3.72 | 14.94 | How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price. |
Reading it: TPL is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.
Before you buy: how RPRX and TPL affect your concentration
The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. RPRX and TPL share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.
This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined RPRX and TPL exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

What does Royalty Pharma (RPRX) do?
Royalty Pharma plc buys the right to receive royalties on approved and development-stage biopharmaceutical products. A university, a research hospital, a small-cap biotech or a large pharmaceutical company owns a royalty on a drug; Royalty Pharma pays a lump sum, sometimes staged across milestones, and thereafter receives a percentage of that drug's top-line sales. The portfolio spans more than 35 marketed therapies and 19 development-stage candidates. In the second quarter of 2026 the largest contributors were Vertex's cystic fibrosis franchise at $194 million of Royalty Receipts, Biogen's Tysabri at $67 million, GSK's Trelegy at $58 million, Johnson & Johnson's Tremfya at $57 million, Roche's Evrysdi at $47 million and Servier's Voranigo at $46 million. Founded in 1996 and public since 2020, the company is incorporated in England and Wales, headquartered in New York, and lists only its Class A ordinary shares on Nasdaq. Until May 16, 2025 it was externally managed and paid a quarterly fee of 6.5% of royalty cash receipts plus 0.25% of security investments; that manager was bought in, and the staff now sit inside the company.
What does Texas Pacific Land (TPL) do?
Texas Pacific Land Corporation owns roughly 880,000 surface acres across West Texas, most of it sitting on the Permian Basin, along with oil and gas royalty interests under about 195,000 net royalty acres. It drills nothing and operates no wells. Large operators including Chevron, ConocoPhillips and Exxon do the drilling on its land, and TPL collects a royalty on the production plus fees for pipeline easements, surface leases, road use, and materials. A second segment, Texas Pacific Water Resources, sells brackish source water for completions and earns royalties on produced water disposed of on TPL acreage. In the second quarter of 2026, oil and gas royalties brought in ~$145.6 million, water sales ~$39.7 million, produced water royalties ~$37.1 million, and easements and other surface income ~$23.7 million.
RPRX vs TPL: how do they differ?
Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.
- RPRX drivers: Royalty Receipts are outrunning the headline receipts number; The internalisation permanently changed the cost line.
- TPL drivers: Royalty volumes on other people's capital; Water: source, produced water royalties, and desalination.
Which fits which kind of investor
A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: Concentration is the first thing to size. For TPL, the valuation is the dominant risk: at roughly 26 times sales and around 45 times trailing earnings, TPL is priced far above producers and mineral peers, so a slowdown in Permian activity gets amplified in the stock rather than cushioned.
RPRX or TPL: which should you pick?
Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick RPRX if you believe its drivers more; TPL if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the RPRX and TPL guides.
RPRX vs TPL: the full fundamentals
RPRX. The ~14 times sales a screener prints comes from dividing a $35.25 billion market cap by $2.54 billion of GAAP revenue, which is the wrong denominator for this structure. Measured against the $3.4 billion to $3.5 billion of Portfolio Receipts guided for 2026, the same market cap is about 10 times, and enterprise value is roughly 13.5 times trailing Adjusted EBITDA. The gap between the trailing P/E near 33 and a forward P/E near 11 is the same effect seen from the earnings side, with non-cash provisions and impairments compressing reported profit while cash collections keep rising.
TPL. TPL trades at roughly 26 times trailing sales and around 45 times trailing earnings, well above its own five-year median and far above any Permian producer. The defense of that multiple is the margin structure and the balance sheet: ~88% adjusted EBITDA margins, ~60% net margins, essentially no debt, and free cash flow that arrives without TPL spending on drilling. The offense against it is that royalty revenue still swings with commodity prices, so the multiple has to survive a soft oil year to be considered durable.
Headline figures (approximate, August 2026): RPRX shows revenue (ttm, gaap) ~$2.54 billion of total income and other revenues for the twelve months to June 30, 2026, against $2,378 million in fiscal 2025, $2,264 million in 2024 and $2,355 million in 2023. GAAP quarterly income was $674 million in the second quarter of 2026, of which $638 million was income from financial royalty assets and $36 million other royalty income. The line is not a sales figure in the ordinary sense: it is the interest component of royalty collections, accreted under the effective interest method off sell-side consensus sales forecasts, so it moves when analysts revise the drugs Royalty Pharma has bought into., portfolio receipts (the operating measure) $3,254 million in 2025, up 16% from $2,801 million in 2024, and $1,698 million in the first half of 2026, up 8.4% from $1,566.8 million. Royalty Receipts, the sales-linked core, were $3,127 million in 2025 and $1,655 million in the first half of 2026 (up 13.4%). Guidance raised on August 5, 2026 puts full-year Portfolio Receipts at $3,400 million to $3,500 million, with Royalty Receipts growth of 7% to 10% and an assumed ~1% currency tailwind, excluding anything transacted after that date., earnings and eps Diluted EPS of $1.86 on a trailing twelve-month basis, from net income attributable to Royalty Pharma plc; GAAP net income was $770.95 million in fiscal 2025 and $858.98 million in 2024. The quarterly path is erratic by design: first-half 2026 diluted EPS was $0.71 on $312.6 million attributable to the plc, but the second quarter alone was $0.04 after a $268 million provision for changes in expected cash flows. Consolidated net income of $549.7 million in the half was reduced by $237.2 million attributable to non-controlling interests before reaching Class A holders., cash flow and adjusted ebitda Net cash provided by operating activities was $1,447 million in the first half of 2026 against $960 million a year earlier, and $2,490 million for full-year 2025. Adjusted EBITDA, defined in the credit agreement as Portfolio Receipts less payments for operating and professional costs, was $736 million in the second quarter and roughly $3.2 billion trailing; Portfolio Cash Flow, after net interest, was $736 million in the quarter and $2,724 million in 2025. Payments for operating and professional costs ran at 4.8% of Portfolio Receipts in the quarter versus 8.9% for all of 2025.; TPL shows revenue (ttm) ~$897M, q2 2026 revenue ~$246M (+31% YoY), q2 2026 adjusted ebitda ~$216M (~88% margin), q2 2026 net income ~$154M (~$2.23 diluted EPS).
The bottom line: RPRX vs TPL

FAQ
What is the difference between RPRX and TPL?
+
Royalty Pharma plc buys the right to receive royalties on approved and development-stage biopharmaceutical products. Texas Pacific Land Corporation owns roughly 880,000 surface acres across West Texas, most of it sitting on the Permian Basin, along with oil and gas royalty interests under about 195,000 net royalty acres. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.
Is RPRX or TPL the better stock?
+
Neither is universally better. RPRX is the larger incumbent; TPL is the smaller challenger and looks cheaper on forward earnings. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.
Which is cheaper, RPRX or TPL?
+
On forward P/E (as of October 2026), RPRX trades at 10.07x and TPL at 4.61x, so TPL is the cheaper of the two on next year's expected earnings. A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.
Should you own both RPRX and TPL?
+
Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.
What are the risks of RPRX vs TPL?
+
RPRX: Concentration is the first thing to size. Vertex's cystic fibrosis franchise supplied 32% of total income and other revenues in the second quarter of 2026 and 33% across the half, and its $194 million of quarterly Royalty Receipts were flat year on year. That royalty is perpetual in contract but the company models a 2039 to 2041 duration on expected Alyftrek patent expiry. There is also an unresolved dispute with the payor: beginning in the second quarter of 2025 Royalty Pharma did not receive what it believes it is contractually owed on Alyftrek net sales and has commenced the contractual dispute resolution procedures, with any recovery recognised only if the matter resolves in its favour. Individual royalties can also go to zero. Ipsen and Eisai withdrew Tazverik across all indications in March 2026, producing a $69.4 million non-cash impairment and the gross write-off of a $548.3 million financial royalty asset. Promacta receipts fell 75% in the quarter on US generic entry and Imbruvica fell 17%, both real cash declines that the growers merely offset. Reported earnings swing on estimates rather than operations: the provision for changes in expected cash flows was a $268 million charge in the second quarter of 2026 against a $204 million benefit a year earlier, which is why net income attributable to the plc fell to $17.9 million and diluted EPS to $0.04. Leverage of $9.2 billion sits ahead of shareholders and drove $187.3 million of interest expense in the half. Tax is a live question too: the company records no income tax expense today, and it flags the UK's adoption of the Pillar Two 15% global minimum tax rules alongside its own statement that its tax position is not free from doubt. TPL: The valuation is the dominant risk: at roughly 26 times sales and around 45 times trailing earnings, TPL is priced far above producers and mineral peers, so a slowdown in Permian activity gets amplified in the stock rather than cushioned. Revenue is levered to oil and gas prices and to operator drilling decisions TPL does not control, and Permian gas has repeatedly cleared at negative prices at the Waha hub when takeaway is tight. Nearly all of the asset base sits in one basin, so any regional constraint on takeaway, water disposal permitting, or seismicity regulation lands on the whole company at once. The water and desalination business is more capital intensive and less proven than the royalty stream, and treated produced water still needs regulatory clearance and buyers at scale before it is a business rather than a pilot. The power and data center opportunity is real but early: one Chevron agreement is a data point, not a run rate, and the multiple already assumes several more follow.
