COHERENT CORP. (COHR) — Fundamental Analysis

Coherent Corp. (COHR) is a global photonics and compound semiconductor company that has grown rapidly over the past several years — largely through acquisitions — but has struggled to translate that scale into consistent profitability. Revenue has nearly doubled since fiscal 2020, compounding at roughly 19–21% annually over three and five years, yet net income has swung in and out of the red as the company absorbed integration costs, depreciation, and heavy debt from its 2022 merger with II-VI Incorporated. The most recent quarter shows encouraging signs: a current ratio back above 3, debt-to-equity falling sharply toward 0.30, and a net margin that jumped to over 10% — the strongest quarterly profit figure in years. The core business is capital-intensive by nature, with capex running at roughly 6–9% of revenue consistently, but that rate appears to be stabilizing rather than escalating. In short, Coherent is a scaled-up, still-maturing business riding strong demand in AI-driven datacom and industrial markets, with its financial health visibly improving but its long-term profitability story still being written.

Snapshot & Big Picture

Coherent Corp. — formerly II-VI Incorporated — designs and manufactures engineered materials, optoelectronics, and laser systems serving datacom, telecom, industrial, and aerospace markets. The company's current scale is largely a product of its March 2022 acquisition of Coherent (the legacy laser company), which roughly doubled revenues and added significant debt. Fiscal year 2025 (ending June 30, 2025) posted revenue of approximately $5.81 billion, up from $4.71 billion in fiscal 2024 — a meaningful acceleration. The longer-term revenue CAGR figures confirm a structural step-change in the business's size, even as profitability has remained inconsistent during the integration period.

Note: Gross margin and operating margin for fiscal year 2025 were not available in the filing data. EBITDA for fiscal 2025 was also not reported in the data provided.

Latest Quarter Snapshot

The most recent quarter ended March 31, 2026 (reported in the 10-Q filed May 6, 2026) represents the most current window into Coherent's financial condition and is more up-to-date than the annual figures above. This quarter is a notable bright spot.

The divergence between the 1.2% operating margin and the 10.6% net margin in this quarter is notable — it suggests a significant below-the-line benefit (such as a tax benefit, asset sale gain, or favorable non-operating item) rather than core operational strength alone. Still, liquidity has improved materially: the current ratio is back above 3.0, and the debt-to-equity ratio has dropped sharply to 0.30 — the lowest level seen across the entire dataset — suggesting meaningful debt paydown or equity improvement is underway.

Profitability

Coherent's profitability history breaks into two clear eras. Before the 2022 mega-merger, the company was consistently profitable, with operating margins in the 10–13% range and positive net margins. After the merger, profitability collapsed: fiscal 2023 saw a –5.0% net margin and negative operating margin as integration costs, amortization of acquired intangibles, and a tougher macro environment weighed heavily. Fiscal 2024 improved slightly to –3.3% net margin with a modest 2.0% operating margin. Fiscal 2025 returned to thin positive net income (0.8% net margin), though operating margin data was not available in the filing. The most recent quarter's 10.6% net margin, if sustained, would represent a genuine inflection — but the gap between operating and net margin warrants scrutiny before declaring the profitability recovery fully durable. EBITDA data, where available, shows the underlying cash earnings power has always been more resilient than GAAP net income, with EBITDA running in the $560M–$700M range in the post-merger years despite GAAP losses.

Financial Health & Capital Expenditures

Coherent's balance sheet has been on a clear improving trajectory after reaching peak leverage in the immediate post-merger period. Debt-to-equity peaked at 0.86 in fiscal 2023 and has declined each year since, reaching 0.65 at fiscal 2025 year-end and an even lower 0.30 in the most recent quarter — a dramatic improvement. The current ratio dipped as low as 2.19 at fiscal 2025 year-end but has since rebounded to 3.05, well above the threshold of concern.

Capital expenditure is a defining feature of this business. As a manufacturer of precision photonics and semiconductor components, Coherent requires ongoing investment in fabrication equipment and facilities. The table below shows the capex trend:

Capex intensity has trended down from 13–14% of revenue in the late 2010s to approximately 7–8% in the post-merger years, with the most recent quarter running at 5.8%. This declining intensity — even as absolute dollar capex has risen — is a positive signal: the larger revenue base is absorbing fixed investment needs more efficiently. It implies the business may be past its heaviest reinvestment phase for now, though manufacturing-intensive businesses like this always carry meaningful ongoing capex obligations.

Growth

The table below summarizes Coherent's trailing revenue CAGR over available windows, computed directly from annual 10-K filings.

The 10-year CAGR is not available because the SEC filing history in this dataset does not extend back a full decade to the required starting fiscal year.

A 3-year CAGR of 20.5% and a 5-year CAGR of 19.5% are both impressive headline numbers, though it is important to note that a meaningful portion of this growth reflects the transformative 2022 acquisition of legacy Coherent rather than purely organic expansion. That said, the fiscal 2025 revenue rebound to $5.81B after a dip in fiscal 2024 suggests underlying demand — particularly from AI infrastructure and datacom transceiver markets — is now providing genuine organic momentum to complement the acquired base.
