Coherent expects $20 billion PhotonLink agreement to ramp in early 2028
Coherent's five-year PhotonLink agreement has a later expected revenue ramp than its March 2027 product-wide sales target. Investors should track those timelines separately.
A large optical-connectivity agreement and a nearer product-sales target are different milestones. Coherent's latest earnings presentation puts both on the page, but on different calendars. Combining them would move the expected contribution from one specific agreement forward by roughly a year.
Coherent, listed on the NYSE as COHR, reported $2.37 billion of revenue for the quarter ended September 30, 2026 in its November 4 results. Its accompanying investor presentation describes a PhotonLink agreement valued at approximately $20 billion over five years, with revenue expected to begin ramping in early calendar 2028.
One product, different revenue clocks
Separately, management expects PhotonLink product revenue to exceed $100 million in the March 2027 quarter. That target covers the product, rather than identifying revenue from the particular five-year agreement.
The deck also reports more than $200 million of first-quarter scale-across and data-center interconnect revenue. That is a reported sales category, separate from the PhotonLink forecast and the longer-term agreement value. These figures should not be added together as if they describe equivalent periods or identical business.
For investors, the nearer PhotonLink sales target offers an earlier checkpoint. Delivery against it would show progress in the product's commercial ramp. It would not, by itself, establish that the later agreement had started contributing.
The approximately $20 billion figure also cannot be treated as cash received, current backlog recognized as sales or five equal annual revenue installments. The materials reviewed do not establish the customer's identity, cancellation rights or minimum guaranteed payments. Those details matter before translating a headline agreement value into an earnings forecast.
Follow recognized sales and management's ramp timing separately. The next useful evidence is how actual PhotonLink revenue develops against the March target, followed by updates on the agreement's expected 2028 contribution. The opportunity can be significant while its timing and financial conversion remain open questions.
