Fiscal 2025 Acquisitions: Nubis Communications

On October 7, 2025, Ciena acquired 100% of the equity in Nubis Communications, a company specializing in high-performance, ultra-compact, low-power optical and electrical interconnects tailored to support AI workloads, including co-packaged optics, near packaged optics and electrical active copper cables that complement Ciena’s optical networking portfolio and high-speed interconnects. Nubis was acquired for an aggregate of approximately $270.5 million. This transaction has been accounted for as the acquisition of a business under ASC 805. The purchase price of $232.6 million was paid in cash at the time of the acquisition. In addition, there were $37.9 million of future payable arrangements including $28.9 million of contingent compensation and $9.0 million of unvested options converted to a right to receive cash over a four year period. These arrangements are tied to future employment and accordingly are being recognized as post-combination compensation expense over the associated service period.

ASC 805 requires that the allocation of the purchase price to the assets acquired and liabilities assumed be based on their fair values as of the acquisition date. Ciena has made the determination of fair values using the best information available at the time. ASC 805 allows Ciena to adjust the provisional amounts recognized in the table below to be adjusted retrospectively for a period no later than one year from the acquisition date in case subsequent events identify a necessary adjustment. These adjustments could materially impact the amounts of goodwill, identified intangible assets, and deferred tax assets.

During fiscal 2025, Ciena incurred approximately $1.1 million in acquisition-related costs associated with this acquisition. These costs and expenses primarily include fees associated with financial, legal, and accounting advisors and employment-related costs. These costs were recorded in acquisition and integration costs on the Consolidated Statements of Operations.

The following table summarizes the preliminary purchase price allocation related to the acquisitions based on the estimated fair value of the acquired assets and assumed liabilities (in thousands):
Amount
Cash and cash equivalents$1,538 
Accounts receivable, net, and prepaid expenses and other227 
ROU assets1,649 
Equipment, furniture and fixtures1,259 
Goodwill76,539 
Developed technology98,000 
In-process technology86,000 
Deferred tax liability, net(29,134)
Accounts payable, Accrued liabilities and other short-term obligations(789)
Lease liabilities(1,649)
Deferred revenue(1,000)
Total purchase consideration$232,640 

Developed technology represents purchased technology that has reached technological feasibility and for which Nubis had substantially completed development as of the date of acquisition. Fair value was determined using the discounted cash flows related to the projected income stream of the developed technology for a discrete projection period. This developed technology will be amortized on a straight-line basis over its estimated useful life of five years.

In-process technology represents purchased technology that had not reached technological feasibility as of the date of acquisition. Fair value was determined using the discounted cash flows related to the projected income stream of the in-process technology for a discrete projection period. Upon completion of the in-process technology, it will be amortized on a straight line basis over its to be estimated useful life.

The goodwill generated from the acquisition of Nubis is primarily related to expected economic synergies. The total goodwill amount was recorded in the Networking Platform segment. The goodwill is not deductible for income tax purposes.
Pro forma disclosures have not been included due to materiality.
Fiscal 2023 Acquisitions: Benu and Tibit
On November 17, 2022, Ciena acquired Benu, a provider of broadband software solutions. On December 30, 2022, Ciena acquired Tibit, a provider of passive optical network hardware and operating software. These businesses were acquired for an aggregate of approximately $291.7 million, of which $244.7 million was paid in cash, and $47.0 million represents the fair value of Ciena’s previously held cost method equity investment in Tibit. The acquisition of Tibit triggered the remeasurement of Ciena’s previously held investment in Tibit to fair value, which resulted in Ciena recognizing a gain on its cost method equity investment of $26.5 million. Each of these transactions has been accounted for as the acquisition of a business.
Ciena incurred approximately $3.4 million in acquisition-related costs associated with these acquisitions. These costs and expenses primarily include fees associated with financial, legal, and accounting advisors and employment-related costs. These costs were recorded in acquisition and integration costs on the Consolidated Statements of Operations.
