Dated and confirmed

Date Event Why it matters Source
~2026-08-10 to 08-19 (window) Q4 / FY2026 results + first FY2027 guide Tests the Q4 guide of $960–1,010m and — the number that matters most — the 35–36% non-GAAP operating margin, which is far above anything LITE has printed and on which the 28.0% terminal margin rests. The FY2027 guide is what the +37.3% target requires (~+64%) FY2025 results 8-K filed 2025-08-12; FY2024 pattern identical. FY2026 date not yet announced — window inferred and labelled
~2026-08-15 to 08-22 (window) FY2026 10-K — the first annual report under single-segment reporting The FY2025 10-K was the last to disclose the Cloud & Networking / Industrial Tech split ($1,410.8m / $234.2m; segment profit $264.5m / $12.1m). This filing will not. It is the point at which the 47.3% revenue decline and 92.1% profit decline in Industrial Tech becomes permanently undetectable. Also carries the FY2026 customer and receivables concentration tables 10-Q Q1FY26 language: "we determined we operate in a single reporting segment"; FY2025 10-K filed 2025-08-19
~2026-11-04 (window) Q1 FY2027 results First read on whether the 35–36% operating margin held for a second quarter, and on whether cloud-transceiver ASP erosion (disclosed qualitatively in the 10-Q) has begun to outpace volume FY2026 Q1 results 8-K filed 2025-11-04
~2026-12-01 (window) Annual meeting Prior-year proxy filed 2025-10-07 for a 2025-11-19 meeting DEF 14A 2025-10-07
~2027-02-03 (window) Q2 FY2027 results CPO and the full OCS ramp should be revenue-bearing and separately quantified by here FY2026 Q2 results 8-K filed 2026-02-03

Company-stated windows without a fixed date

Window Event Company language Consequence
Mid-CY2026 LITE's own 1.6T transceivers begin shipping "We have expectation to be shipping 1.6T transceivers sometime in the middle of next year, and those will be at the early part of the customer ramp" (CEO) The single most important product date on this name. COHR is already in 1.6T revenue; LITE is roughly a year behind on its own module
Late Q2 CY2026 102.4T switch silicon availability — the industry gate on 1.6T transceiver qualification "102.4 switch until really, I would say, late Q2 next year calendar" (President, Global Business Units) An industry-wide gate, not LITE-specific. It sets the earliest date at which broad 1.6T module demand can qualify, and it slips for everyone if the silicon slips
Ongoing, 6–8 quarters Capacity ramp under multiyear customer commitments "Those customers in return have given us multiyear commitments... as we continue to ramp capacity through the next probably 6 or 8 quarters" Asserted, not quantified — no value, term or counterparty. This is the gap between the required 49.61% CAGR and what is evidenced
Ongoing Greensboro gallium-arsenide → indium phosphide conversion "plans to convert the facility from gallium arsenide to indium phosphide are well underway... we expect to take advantage of a significant number of the tools that already exist" A capital-efficient route into the constraint currently rationing COHR's datacenter growth
CY2026–27 CPO first material revenue "we are only just beginning to unlock the massive potential of OCS and CPO" CPO is the most-interrogated topic in the cluster (15 prepared / 8 in Q&A), and the technology that would restructure the value chain
No date given $2 billion quarterly revenue goal "our $2 billion quarterly revenue goal as we articulated at our OFC event" $8bn annualised — less than half the $18.7bn FY2031 revenue the current price requires. The company's own ambition does not reach the required level, and no date is attached
~March 2027 OFC 2027 LITE has used OFC as its OCS/CPO/1.6T disclosure venue and to set revenue milestones Historically the highest-density product-news event

Capital-structure events — unique to this name, and they are calendar items

Item Detail Consequence
Convertible note conversions, continuous As of 2026-04-30 LITE had received early conversion requests totalling $500.8m of principal, settling principal in cash and the excess in shares. All four series are in the money (2029 Notes at $69.54 against a $602 share price) Each conversion is a cash outflow of principal plus share issuance. The diluted count is a function of the share price and rises as the stock rises
2026 Notes maturity $468.7m principal outstanding after an $843.1m partial repurchase funded from the 2032 Notes Near-term cash claim
NVIDIA Series A Preferred 2.9m shares at $695.31, issued 2026-03-02, 1:1 convertible at holder option after HSR clearance HSR expiry/termination is an unscheduled but real event — it is the point at which NVIDIA may convert. NVIDIA is currently 15.4% under water on the position

What is NOT on this calendar, and why

Monitoring triggers, not catalysts

  1. Non-GAAP operating margin. Guided 35–36% for Q4 FY2026. The 28.0% terminal margin — and therefore the entire PASS — rests on this being real and durable. Two consecutive prints below 30% invalidates.
  2. Cloud transceiver revenue growth versus unit shipment growth. The 10-Q already discloses growth "partially offset by lower average selling prices." When revenue growth falls below unit growth for two consecutive quarters, ASP deflation has taken over — the named bear case.
  3. Customer concentration. Top customer went 16.0% (FY2025) → 24% (9M FY26) → 26% (Q3 FY26). And receivable concentration went 13% → 25%. Watch for the receivable share exceeding the revenue share — the AAOI signature. It is currently −1pp.
  4. Fully diluted share count in each 10-Q's EPS note, against the ~102m guided. This is the input no vendor field carries and the one most likely to drift.
