Both bases are carried through the whole document. The pro-forma basis is the primary one — it is what an investor buys today — and it is labelled as an estimate everywhere it appears. Operating lease liabilities of ~$470m (current + non-current) are not in either EV; a book that treats leases as debt should add ~$4.67 per share of EV.


2. Implied-path test — the Valuation Criteria

2.1 Anchoring the exit multiple — GROWTH_MATCHED

The 129-name Tier-1 universe in reports/scan_v2 contains no commercial-stage biopharma peer — the only pharma-adjacent name is JNJ, a conglomerate. Anchoring NBIX to MSFT, AVGO or ANET because they happen to grow at a similar rate would satisfy the letter of the growth-match rule and violate its purpose. A comparator set was therefore built from EDGAR + Alpaca specifically for this memo.

Comparator set: US-listed commercial-stage biopharma, growth bracketing 5–15%, positive EBIT. Growth is three-year revenue CAGR to the latest fiscal year; EV/EBIT on trailing twelve months, net cash from the latest balance sheet.

Comparator 3-yr revenue CAGR EV/EBIT EBIT margin TTM revenue
Regeneron (REGN) 5.6% 13.5x 24.3% $14,920m
Exelixis (EXEL) 8.2% 14.5x 37.6% $2,320m
Alkermes (ALKS) 9.9% 51.3x 11.3% $1,581m
Vertex (VRTX) 10.4% 23.8x 38.3% $12,218m
Incyte (INCY) 14.8% 13.9x 30.0% $5,361m
n = 5 · median 9.9% 14.5x 30.0%

Reference points outside the growth bracket, shown for range but not used to set the base: United Therapeutics 18.0% / 13.0x; BioMarin 15.4% / 35.6x; Halozyme 28.4% / 22.6x; Alnylam 53.0% / 72.8x; ACADIA 27.5% / 44.5x.

The bracket is set to the exit-year growth rate, not the historical one. NBIX's demonstrated three-year CAGR is 24.3%, but by year 5 (2031) INGREZZA is a mature ~$3.5bn franchise, CRENESSITY and VYKAT XR are past their launch curves, and growth depends on whether osavampator or direclidine reach market. A 9–12% exit-year growth rate is the reasonable central expectation, and the comparator set spans 5.6%–14.8%, which brackets it. Basis: GROWTH_MATCHED.

Base exit multiple: 18.0x EV/EBIT. It sits above the set median of 14.5x and below Vertex at 23.8x, i.e. inside the anchor range and above the lowest anchor — the rule that the base may not sit below every stated anchor is satisfied without needing a separate argument. Alkermes at 51.3x is an EBIT-denominator artifact (11.3% margin) and does not pull the base up; Regeneron and Incyte at 13.5x/13.9x are names with visible LOE overhang, which NBIX does not have inside the five-year window (§ Research 4). Implied compression from today's 19.9x traded EV/EBIT: −1.9x, or a 9.5% multiple compression. Stated as a number, as the spec requires.

2.2 Terminal margin

30.0%, held fixed. Basis, stated with the argument because it does not simply take the peer median: - Own, demonstrated: TTM GAAP EBIT margin 25.4%; FY2025 non-GAAP operating margin 29.6% ($845.5m / $2,860.5m); Q1 2026 non-GAAP operating margin 27.8%. - Pharma comparator median EBIT margin: 30.0% (set above) — and 34% across the wider set including UTHR, HALO and VRTX. - 30.0% is the peer median and roughly the company's own current non-GAAP operating margin. It is not the max(own, peer median) convention taken to the wider-set 34%, and the reason is stated: NBIX runs R&D at 35.5% of revenue against two simultaneous Phase 3 programmes. Assuming that normalises all the way to the wider peer level would be assuming the pipeline stops, which contradicts the mechanism the memo credits.

2.3 The test

python3 reverse_dcf.py --spot 182.13 --shares 100.582 --net-cash 226.0 \
    --revenue 3387.4 --years 5 --wacc 0.10 \
    --terminal-margin 0.30 --exit-multiple 18.0

Parameters held fixed: horizon 5 years; WACC 10.0%; terminal EBIT margin 30.0%; exit multiple 18.0x EV/EBIT; shares 100.582m; net cash $226m (pro forma, estimated); starting revenue $3,387.4m (NBIX TTM + VYKAT TTM). Solved for: revenue CAGR.

Pro forma (primary) As-reported 2026-03-31 (secondary)
Net cash $226m (est.) $2,647.2m
Starting revenue $3,387.4m $3,102.4m
Enterprise value $18,093.0m $15,671.8m
Required revenue CAGR +9.76% +8.54%
Demonstrated (FY2022→FY2025) +24.3% +24.3%
MARGIN +14.5pp +15.8pp
Result PASS PASS

Terminal value is 100% of modelled EV by construction, so the reverse DCF is the primary long-horizon output and the sensitivity runs on the multiple.

The margin at other defensible definitions of "demonstrated":

Definition Value Margin vs +9.76% required
Three-year CAGR FY2022→FY2025 (organic) +24.3% +14.5pp ← used
TTM growth (TTM $3,102.4m vs prior TTM $2,355.3m) +31.7% +21.9pp
FY2025 reported +21.4% +11.6pp
INGREZZA alone, FY2025 +8.7% −1.1pp
Company FY2026 INGREZZA guidance midpoint +9.4% −0.4pp
Two-year INGREZZA stack (Q1'26 vs Q1'24) +13.9% +4.1pp

This is the honest frame and it should not be buried. Total-company growth clears the required path comfortably. INGREZZA alone — 84.6% of trailing revenue — does not. The +14.5pp margin is entirely attributable to CRENESSITY and VYKAT XR growing into the mix. That is exactly the mechanism the Research document credits, and it is the correct thing to underwrite — but the test is a bet on the de-concentration working, not on the base franchise.

2.4 Sensitivity over the exit multiple (mandatory — never over scenario probabilities)

Pro-forma basis. Terminal margin 30.0%, WACC 10.0%, revenue $3,387.4m, horizon 5 years, net cash $226m.

Exit multiple (EV/EBIT) Required revenue CAGR Margin vs +24.3% Margin vs +13.9% (INGREZZA 2-yr stack) Note
12.0x +19.03% +5.3pp −5.1pp below every anchor; the §7 downside case
13.5x +16.26% +8.0pp −2.4pp = REGN
13.9x +15.58% +8.7pp −1.7pp = INCY
14.5x +14.61% +9.7pp −0.7pp = EXEL, comparator median
18.0x (base) +9.76% +14.5pp +4.1pp
19.9x (today's traded) +7.58% +16.7pp +6.3pp
20.0x +7.47% +16.8pp +6.4pp
23.8x +3.80% +20.5pp +10.1pp = VRTX
26.0x +1.98% +22.3pp +11.9pp

The test does not flip anywhere in the plausible multiple range on total-company growth — even at 12.0x, below every stated anchor, the required +19.0% CAGR still sits below the demonstrated +24.3%. That is a materially more robust pass than GMED's in this same batch, which inverts at 17.5x.

But on INGREZZA's own two-year stack of +13.9%, the flip point is 15.2x (at 15.3x the required CAGR is +13.39%, a margin of just +0.5pp) — between Exelixis and Vertex. Both columns are shown because they answer different questions, and a book should know which one it is underwriting.

Effect of the Soleno deal on the test, isolated: it raises the required CAGR from +8.54% to +9.76% (+1.2pp), because $2.9bn of cash left the balance sheet in exchange for $285m of trailing revenue. Deals that lower a required path add more revenue per dollar of cash than this one did. The deal made the implied-path test modestly harder to pass, not easier.


3. The 12-month target

Built per valuation.md: near-term estimates + named product-cycle events, multiple anchored on NBIX's own trading history with the percentile stated. Not a DCF; not a peer median.

3.1 Near-term revenue base

No Street consensus was obtainable (Alpha Vantage quota exhausted). NBIX guides INGREZZA only — there is no company guidance for CRENESSITY, VYKAT XR or total revenue. The build below is therefore part guidance and part house estimate, and every line is labelled so the assumption can be attacked rather than inherited.

($m) FY2026E Basis FY2027E Basis
INGREZZA 2,750 GUIDANCE midpoint of $2,700–2,800m, reaffirmed 2026-05-07 3,000 HOUSE: +9.1%, consistent with the +13.9% two-year stack decaying toward the FY2026 guided rate
CRENESSITY 700 HOUSE: Q1'26 actual $153.3m plus three quarters averaging ~$182m; FY2025 was $301.2m and Q4'25 alone was $135.3m 1,000 HOUSE: +43%, second full year of a launch with 7-year orphan exclusivity
VYKAT XR 240 HOUSE: owned from 2026-05-18, ~7.5 months at the Q1'26 run rate of $94.6m/qtr 450 HOUSE: first full year at ~$113m/qtr, +19% on the Q1'26 run rate
Other (AbbVie/Tanabe royalties) 15 HOUSE: FY2025 was $45.6m; Q1'26 fell to $4.3m after the Neurocrine Group Limited divestiture 15 HOUSE
Total 3,705 4,465
NTM revenue (5/12 × FY26 + 7/12 × FY27) $4,149m 5 months of FY2026 remain as of 2026-07-29

Named product-cycle events inside the 12-month window that move this base — each dated in NBIX_Catalyst_Calendar.md: - Q2 2026 results (~30 July 2026, i.e. imminent) — first quarter of VYKAT XR consolidation, first Soleno purchase accounting, and the test of whether INGREZZA's Q1 re-acceleration was the comp or the trend. - CRENESSITY sequential trajectory — the Q1'26 add halved. Two more quarters define the launch's asymptote, and the FY2027 CRENESSITY line above is the largest single house assumption in the build. - Zydus INGREZZA SPRINKLE litigation — D. Delaware. No trial date is disclosed. Any ruling or settlement inside the window is a step change in either direction. - osavampator and direclidine Phase 3 progression — no topline date has been disclosed for either. No date is asserted here.

3.2 Multiple — anchored on NBIX's own history

Daily EV/Sales series on as-known TTM revenue (each quarter stepped in at its actual filing date), with the current verified share count and the 2026-03-31 net cash held constant so the series measures multiple movement.

Window n Current Percentile min p25 median p75 p90 max
Full available (2021-05-05 → 2026-07-29) 1,314 5.05x 48th 2.62x 4.40x 5.13x 5.98x 6.62x 7.71x
Post-2023-09 728 5.05x 67th 2.62x 4.14x 4.55x 5.41x 5.94x 6.58x

Annual mean EV/Sales: 2021 6.50x · 2022 5.91x · 2023 4.99x · 2024 5.39x · 2025 4.27x · 2026 YTD 4.08x.

On the pro-forma basis (EV $18,093m on pro-forma TTM revenue $3,387.4m) the current multiple is 5.34x, which maps to roughly the 60th percentile of the full window and the high-70s of the post-2023 window. NBIX is mid-range on its own five-year history and upper-half on its recent history — not cheap, not extended.

Target multiple: 5.13x EV/Sales — the median of the full available window. This is deliberately the least aggressive anchor available: it assumes the multiple neither expands nor contracts from its own five-year central tendency. The full window rather than the post-2023 window is used because NBIX has not undergone a structural change comparable to GMED's merger; it is the same company across the whole series, and the wider sample is the better estimator.

3.3 The target

NTM revenue $4,149m
× target EV/Sales 5.13x
= Target enterprise value $21,284m
+ Net cash, 12 months forward $1,150m (pro-forma ~$226m + ~$900m of free cash flow over four quarters; FY2025 FCF was $748.7m and the revenue base is now ~30% larger)
= Target equity value $22,434m
÷ Shares, 12 months forward 102.5m (100.582m plus net dilution; FY2025 diluted average was 102.5m and buybacks have been modest at $167.7m in FY2025, $54.0m in Q1'26)
= 12-month target $218.87 ≈ $219
vs spot $182.13 +20.2%, ABOVE spot

Cross-check on earnings, not used to set the target. FY2025 non-GAAP diluted EPS was $6.39; Q1 2026 was $1.94, annualising to $7.76. At $219 that is 34.3x FY2025 non-GAAP EPS and 28.2x the Q1'26 annualised rate; the stock currently trades at 28.5x and 23.5x respectively. A caution belongs with this cross-check: FY2025 non-GAAP EPS grew +0.9% while revenue grew +21.4% (Research §3.2). A P/E anchor on a flat-EPS year is not a reliable instrument here, which is precisely why valuation.md specifies the revenue-multiple anchor as primary and the P/E as a check.

Sanity band. No external professional target exists for NBIX in the reference book, so there is nothing to check the output against. That absence is stated rather than substituted for: the GMED target in this same batch has a $62 external reference to argue with; this one does not, and it is therefore the less-constrained of the two.

The target's honest sensitivity: it is roughly 41% driven by house estimates (CRENESSITY FY2027 $1,000m and VYKAT FY2027 $450m together are $1,450m of the $4,465m FY2027 line). If CRENESSITY plateaus at the Q1'26 annualised $613m and VYKAT at $380m, NTM revenue falls to $3,846m (FY2026E $3,618m, FY2027E $4,008m) and the target to $204 (+11.8%) on the same multiple. That downside-to-the-estimate case still sits above spot, which is the useful thing to know.


4. Summary

Implied-path test (pro forma) Required CAGR +9.76% at 18.0x GROWTH_MATCHED exit / 30.0% terminal margin; demonstrated +24.3%; margin +14.5pp; PASS, and it does not flip anywhere in the plausible multiple range
Implied-path test (as-reported 2026-03-31) Required +8.54%; margin +15.8pp
The Soleno effect, isolated Raises the required CAGR by +1.2pp — the deal made the test harder, not easier
12-month target $219 (+20.2%) — 5.13x EV/Sales (the median of its own five-year range) on $4,149m NTM revenue
Own-multiple percentile 5.05x reported = 48th percentile of 5.2 years, 67th post-2023; 5.34x pro forma ≈ 60th
Peer spread +1.77x EV/Sales premium to ACAD = 67th percentile of that spread's history
The load-bearing caveat On INGREZZA's own growth (84.6% of revenue), the required path is not cleared. The pass is a bet on CRENESSITY and VYKAT XR growing into the mix.
