Catalysts
This page lists dated near-term and long-term events that could materially move the COHR thesis. Catalysts are categorized by type (earnings / operational / strategic / regulatory) and rated by expected impact (low / medium / high). Each catalyst includes the expected date, what bullish vs bearish outcomes look like, and the relevant cross-link.

| Expected date | Q4 CY2026 (= ~Q2 FY2027) |
| Expected impact | Medium-High |
| Bullish outcome | Internal InP capacity doubled on schedule; 200G EML supply meaningfully relaxed; ASP discipline holds despite capacity addition |

| Cross-link | 05_financials capex cycle, 04_market InP EML duopoly |

| Field | Value |
|---|---|
| Type | Strategic |
| Expected date | Variable; likely visible in Q3 FY2026 + Q4 FY2026 earnings |

Long-term catalysts (12–36 months — through April 2029)
C8 — CPO commercial-volume launch
| Field | Value |
|---|---|
| Type | Strategic / industry |
| Expected date | CY2027 first commercial volume; CY2028 NVLink-scale-up CPO ramp |
| Expected impact | Very High |

C9 — Series B Convertible Preferred conversion
| Field | Value |
|---|---|
| Type | Capital-structure |
| Expected date | Variable; depends on Bain Capital (BCPE Watson SPV) portfolio decisions — Bain is the sole Series B holder; the November 2025 dividend waiver (eliminating both ongoing 5% PIK accretion and the post-year-four cash-pay step) hints at multi-year hold horizon |
| Expected impact | Medium (dilution timing at the $85.00 optional conversion strike) |
| Bullish outcome | Conversion timing aligns with broader share-count optimization (e.g., post-FCF-inflection buyback offsets dilution); Bain stages conversion to allow ordered LP distributions |
| Bearish outcome | Series B converts en masse before share-count-optimization framework is in place; meaningful incremental dilution at the deeply-ITM $85 strike |
| What to watch | BCPE Watson SPV 13G/13D amendments; quarterly Series B outstanding face disclosures (capturing PIK accretion through Nov 20, 2025); diluted-share-count trajectory |

C10 — FCF inflection and potential buyback program
| Field | Value |
|---|---|
| Type | Capital-allocation |

| Expected impact | Medium |
| Bullish outcome | Free cash flow inflects past $750M+ in FY2028; share-count-optimization announcement (potential repurchase program); dividend initiation discussion |
| Bearish outcome | FCF inflection delayed; capex envelope sustains beyond FY2028; share-count grows without offset |
| What to watch | OCF and capex trajectory; capital-allocation commentary on earnings calls |
| Cross-link | 05_financials DCF assumptions, 05_financials capex cycle |
C11 — Hyperscaler-direct CPO procurement (post-NVDA)
| Field | Value |
|---|---|
| Type | Market structural |
| Expected date | CY2028+ |
| Expected impact | High |
| Bullish outcome | Microsoft, Meta, Google, AWS issue CPO procurement RFPs; Coherent wins meaningful hyperscaler CPO share beyond NVDA |
| Bearish outcome | Hyperscaler-direct CPO procurement delayed beyond 2028; consolidates with non-Coherent CPO-engine vendors |
| What to watch | Hyperscaler procurement commentary; Coherent CPO customer-win disclosures |
| Cross-link | 04_market CPO market, 03_ecosystem hyperscaler customers |
C12 — CHIPS Act direct grant award (if any)
| Field | Value |
|---|---|
| Type | Regulatory / economic |
| Expected date | Variable through CY2026–CY2028 |
| Expected impact | Low-Medium |
| Bullish outcome | Federal CHIPS grant announced for InP fab build; cash-flow uplift; signaling effect for follow-on grants |
| Bearish outcome | No specific federal grant; rely on the 25% ITC alone |
| What to watch | Department of Commerce CHIPS Office announcements; specific Coherent disclosures |
