Model Notes

MannKind Corporation [MNKD] — Financial Model Notes

Every derived figure in this memo, with its arithmetic, so any number can be checked without re-running anything. No Excel workbook was built — the analysis is driven by segment disclosure and a reverse DCF, neither of which needs one, and the time-box directed effort to the accounting-quality and valuation work per the brief's priority order. That omission is stated rather than concealed.

Underlying data files are in data/: - mentions.json — raw mention counts and source URLs for all 30 earnings press releases - evsales.json — the daily EV/Sales series (1,309 sessions) behind the percentile table - bsdata.py — the 21-quarter point-in-time balance-sheet table used to build it


1. Revenue: quarterly, derived, reconciled

Q4 is not separately tagged by US registrants. Every Q4 below is derived as FY − (Q1+Q2+Q3) and the FY figure is the tagged 10-K number.

2025 Q4 111,955 348,966 − 237,011
2026 Q1 90,171 tagged

TTM (Q2 2025 – Q1 2026) = 76,527 + 82,130 + 111,955 + 90,171 = $360,783k. Equivalently FY2025 − Q1'25 + Q1'26 = 348,966 − 78,354 + 90,171 = $360,783k. Ties to the screen exactly. Not a 15-month window — the four periods are consecutive and were checked to be so.

Prior-year TTM (Q2 2024 – Q1 2025) = 72,386 + 70,079 + 76,776 + 78,354 = $297,595k.


2. The revenue split, by line, TTM

TTM line = FY2025 − Q1 2025 + Q1 2026, from the face of the income statement in each filing.

$000 FY2025 − Q1 2025 + Q1 2026 TTM % of TTM
Commercial product sales 114,137 (18,973) 33,907 129,071 35.8%
Collaborations and services 106,713 (29,376) 23,515 100,852 28.0%
Royalties 128,116 (30,005) 32,749 130,860 36.3%
Total 348,966 (78,354) 90,171 360,783 100%

United Therapeutics-derived = 100,852 + 130,860 = $231,712k = 64.2% of TTM revenue.


3. Product-level reconstruction (derived — carries ±$1m of rounding)

Individual products are not separately XBRL-tagged. Reconstructed from MD&A gross revenue, gross-to-net percentage and stated dollar changes, then cross-checked to sum to the tagged Commercial product sales line.

Q1 2026 (10-Q MD&A): - Furoscix: gross $20.9m, gross-to-net 26% ($5.4m) → net $15.5m (stated directly) - Afrezza: gross-to-net 31% = $6.8m; net revenue "+$0.4m, or 3%" on Q1'25's ~$14.8m → net ≈ $15.2m - V-Go: gross-to-net 36% = $1.8m; net "−$0.9m, or −23%" on Q1'25's ~$4.1m → net ≈ $3.2m - Check: 15.5 + 15.2 + 3.2 = 33.9 ≈ tagged $33,907k ✓

FY2025 (10-K MD&A): - Furoscix (7 Oct – 31 Dec stub): gross $32.4m, gross-to-net 28% → net $23.2m (stated directly) - V-Go: gross-to-net 38% = $9.8m → gross $25.8m → net ≈ $16.0m - Afrezza: residual → 114,137 − 23,200 − 16,000 = net ≈ $74.9m (MD&A says net rose "$10.5m, or 16%", implying ~$76.1m from a ~$65.6m base — the two routes differ by ~$1m of rounding; $75m is used) - Check: 23.2 + 16.0 + 74.9 = 114.1 = tagged $114,137k ✓

TTM by product: Afrezza ≈ 75.0 − 14.8 + 15.2 = $75.4m · V-Go ≈ 16.0 − 4.1 + 3.2 = $15.1m · Furoscix = 23.2 + 15.5 = $38.7m. Sum $129.2m vs tagged $129.071m — a $0.13m rounding gap. ✓


4. The organic calculation

Q1 2026: 90,171 − 15,500 = 74,671 vs Q1 2025's 78,354 → −4.70%.

TTM: 360,783 − 38,700 = 322,083 vs prior-year TTM 297,595 → +8.23%. (Prior-year TTM contains no Furoscix — MannKind did not own it until 7 Oct 2025 — so the comparison is clean on both sides.)


5. Contribution to the 51.8% CAGR

FY2022 → FY2025, total increase $249,196k:

Line FY2022 FY2025 Δ % of total Δ line CAGR
Royalties 15,599 128,116 +112,517 45.16% (128,116/15,599)^⅓ − 1 = 102.0%
Collaborations & services 27,924 106,713 +78,789 31.62% (106,713/27,924)^⅓ − 1 = 56.4%
Commercial product sales 56,247 114,137 +57,890 23.23% (114,137/56,247)^⅓ − 1 = 26.5%
— of which acquired Furoscix 23,200 +23,200 9.31% n/a
— of which organic 56,247 90,937 +34,690 13.92% 17.3%
Total 99,770 348,966 +249,196 100% (348,966/99,770)^⅓ − 1 = 51.8%

United Therapeutics = 45.16 + 31.62 = 76.78% of the three-year increase. Screen's 51.8% reproduced exactly, confirming FY2022 → FY2025 is the window it used.


6. scPharmaceuticals: isolating the acquired revenue

From the 10-K FY2025 supplemental pro-forma disclosure (Note 3):

FY2025 FY2024
Pro-forma combined revenue $396,150k $321,836k
MannKind as reported $348,966k $285,504k
Difference = scPharma pre-acquisition period $47,184k (1 Jan – 6 Oct 2025, 279 days) $36,332k (full FY2024, 366 days)

Per-day run rates: - scPharma Jan–Oct 2025: 47,184 / 279 = $169k/day - Q4 2025 stub under MannKind: 23,200 / 85 = $273k/day - Q1 2026: 15,500 / 90 = $172k/day - scPharma FY2024: 36,332 / 366 = $99k/day

Underlying growth: $172k/day vs $99k/day = +73% year-on-year. The $273k/day Q4 stub is the outlier (+61% above both the quarter before it and the quarter after it) and is most plausibly channel stocking around the acquisition plus Q4 deductible seasonality — flagged as an open question in the Research doc, not asserted.


7. Margins and returns

$000 FY2024 FY2025 TTM
Revenue 285,504 348,966 360,783
Operating income (EBIT) 72,587 38,801 14,841
Operating margin 25.4% 11.1% 4.1%
Net income (loss) 27,588 5,863 (23,914)
Cash from operations 42,511 18,255 19,267
Stock-based compensation 21,358 24,195 ~25,265

TTM EBIT = 38,801 − 22,293 + (1,667) = $14,841k. TTM net income = 5,863 − 13,158 + (16,619) = $(23,914)k. TTM operating cash flow = 18,255 − (6,377) + (5,365) = $19,267k.

The screen's op_margin_pct: 11.1 is the FY2025 figure applied against TTM revenue. That period mismatch is what produces ev_ebit: 28.7: $1,152m ÷ (11.1% × $360.8m = $40.0m) = 28.8x. Using the corrected EV of $1,440m and the actual TTM EBIT of $14.8m gives 97.0x.

Gross margin (not tagged; the screen returned null):

$000 TTM
Cost of goods sold — commercial 26,800 − 3,768 + 7,509 = 30,541
Cost of revenue — collaborations & services 61,160 − 13,748 + 9,964 = 57,376
Amortisation of acquired intangibles 3,973 − 0 + 4,367 = 8,340
Gross profit ex-amortisation 360,783 − 87,917 = 272,86675.6%
Gross profit incl. amortisation 360,783 − 96,257 = 264,52673.3%

Flattered by mix: royalties are 36.3% of revenue and carry no cost of revenue at all. Collaborations and services gross margin is (100,852 − 57,376) / 100,852 = 43.1%.

ROIC: NOPAT ≈ TTM EBIT $14.8m (full valuation allowance, no cash tax). Invested capital = term loan $318.7m + Sagard royalty liability $150.6m + Danbury financing liability $103.2m + stockholders' deficit $(59.2)m = $513.3m. ROIC ≈ 2.9% vs WACC ≈ 11.7%.


8. Net debt — the $246.5m correction

$000, 31 Mar 2026
Cash and cash equivalents 52,834
Short-term investments 81,027
Long-term investments
Liquid resources 133,861
Blackstone term loan (principal $325,000; carrying) 318,722
Net debt (narrow) (191,139)
Sagard liability for sale of future royalties (14,010 + 136,561) 150,571
Danbury financing liability (10,407 + 92,784) 103,191
Net debt (broad) (444,901)

Cross-checked to the 10-Q's own MD&A sentence: "As of March 31, 2026, we had capital resources comprised of cash, cash equivalents and investments totaling $133.9 million, and total principal amount of outstanding borrowings of $325.0 million."

Balance sheet cross-foot (all in $000): current assets 52,834 + 81,027 + 28,137 + 49,166 + 39,996 = 251,160 ✓ tagged. Total assets 251,160 + 747 + 0 + 82,554 + 67,595 + 185,708 + 129,600 + 5,024 + 22,015 = 744,403 ✓ tagged — which is how "Long-term investments $5,012k" was assigned to the December column rather than March. Total liabilities sum to 803,598 ✓. Equity (59,195) ✓.

Pro forma for the two known July events: 133,861 + ~47,000 (net placement proceeds after expenses) − 45,000 (CVR payment) = ~$135,861k. Q2 2026 operating burn is not included; Q2 2026 is unfiled.


9. Shares

Outstanding, 31 Mar 2026 (10-Q balance-sheet parenthetical) 308,907,331
+ private placement shares (8-K 2026-07-24) 10,440,838
+ pre-funded warrants, $0.01 strike, no expiry (same 8-K) 2,412,632
Economic share count 321,760,801
Other potentially dilutive at 31 Mar 2026 (10-Q EPS note): 3.0m RSUs + 3.5m options/PNQs 6,500,000
12-month assumption used in the target 325,800,000

EPS cross-check. Q1 2026: $(16,619)k ÷ 308,267k weighted basic = $(0.054) vs filed $(0.05) ✓. FY2025: $5,863k ÷ 305,639k = $0.019 vs filed $0.02 ✓. Single share class — the dual-class XBRL-aggregation caveat does not apply.


10. The EV/Sales history series

data/evsales.json, 1,309 trading days, 2021-05-12 → 2026-07-29. Construction:

  1. Daily closes, Alpaca SIP feed, split- and dividend-adjusted.
  2. TTM revenue as known at that date — stepped in at the actual 10-K / 10-Q filing date from the SEC submissions index, never at the period end. The series is therefore not forward-looking.
  3. Point-in-time share count and net debt from XBRL instant facts, taken at the most recent balance-sheet date at or before the revenue period end (data/bsdata.py, 21 quarters). This deliberately departs from the framework helper's approach of holding shares and net cash at today's verified values. For MannKind that would be wrong: net debt moved from +$50m net cash to −$191m and shares from 249m to 309m inside the window, and freezing them would put the entire balance-sheet change into the multiple.
  4. EV = close × shares_pit + net_debt_pit; EV/Sales = EV ÷ TTM_as_known.

Percentiles are in MNKD_Valuation.md §3.3.


11. Reverse DCF parameterisation

assets/reverse_dcf.py, solving for cagr, 5-year horizon, EV computed as spot × shares − net_cash.

Run --shares --net-cash --terminal-margin --exit-multiple --wacc Result
Screen reproduction 308.950 +57.415 0.162 22.6 0.10 7.03%
Corrected, base 321.761 −182.8 0.162 22.6 0.10 11.82%

Corrected, broad EV 321.761 −436.6 0.162 22.6 0.10 15.52%

(−182.8 rather than −189.1 because the reverse-DCF runs use the term loan's carrying amount $318.722m rather than the $325.0m principal, for consistency with the balance sheet. The difference is $6.3m of unamortised issuance costs and moves the required CAGR by under 0.1pp.)

Full sensitivity grids over exit multiple, WACC and terminal margin are in MNKD_Valuation.md §2.4.


12. What was NOT built, and why
