The tape

SPY closed at $773.17, up 1.05%, while QQQ gained 1.19% to $717.67 in Thursday's session. Across the 523-company AI infrastructure universe, 352 names advanced, 164 declined, and 7 finished flat, for an average move of +0.97% — a 0.08% underperformance relative to SPY. Operators led all segments at +5.62%; the weakest segments were natural resources (-0.57%), networking (-0.43%), and chip making (-0.18%). BTBT (Bit Digital, Inc.) was the standout at +17.3% amid a broad crypto-adjacent operator bid, while MEI (Methode Electronics, Inc.) fell 15.4% as the biggest decliner. Next week's earnings slate includes ABM (ABM Industries Inc.) on Tuesday and ORCL (Oracle Corporation) on Thursday.

What reported

CIEN (Ciena Corporation) reported fiscal third-quarter EPS of $2.11, above the $1.73 consensus estimate — a $0.38 beat. The stock nevertheless closed down 10.4% on Thursday, the second-worst decliner overall. The company released results via 8-K and press release after the close.

TTC (The Toro Company) delivered EPS of $1.33 against a $1.31 estimate, a $0.02 beat. Shares fell 6.8% on the session, the worst performance in the construction segment, which averaged +0.46%.

BBCP (Concrete Pumping Holdings, Inc.) posted EPS of $0.09 versus a $0.08 estimate, a $0.01 beat, and announced the initiation of a quarterly dividend alongside its third-quarter fiscal 2026 results.

CIEN (Ciena Corporation)'s $0.38 EPS beat could point to continued strength in AI-driven optical networking demand — a potential positive signal for optical component suppliers such as COHR (Coherent, Inc.) and LITE (Lumentum Holdings Inc.).
CIEN (Ciena Corporation)'s results may also read through to data center optical interconnect demand. AAOI (Applied Optoelectronics, Inc.) is a documented supplier to MSFT (Microsoft Corporation) and ORCL (Oracle Corporation) in the data center optical market and could see follow-on demand if hyperscaler bandwidth spending remains elevated. The 10.4% selloff in CIEN shares, however, indicates the market was looking for more.
BBCP (Concrete Pumping Holdings, Inc.)'s beat and dividend initiation could be a modestly encouraging data point for commercial and industrial concrete placement, including data center construction. Concrete pumping demand can serve as an early indicator for construction volumes.
TTC (The Toro Company)'s modest EPS beat paired with a 6.8% selloff may reflect positioning more than fundamentals. Its underground and specialty construction equipment tied to utility and data center site work remains a relevant demand barometer for construction-adjacent activity.
What's happening

FLEX (Flex Ltd.) announced a definitive agreement to acquire EPC Power for $4.4 billion, adding power conversion capabilities for AI data centers and grid applications. EPC Power designs and manufactures power conversion systems used in data center power architectures and grid-tied energy storage.

CWK (Cushman & Wakefield plc) released its 2026 Data Center Development Cost Guide, citing a 21% rise in per-megawatt construction costs. The report quantifies what construction contractors and data center developers have been navigating — higher labor, materials, and power delivery costs.

CIFR (Cipher Mining Inc.) announced that Cipher Digital has begun development of lateral pipelines to facilitate data center expansion via a bring-your-own-generation model. The pipeline work is tied to the company's effort to source power independently for data center capacity, rather than relying solely on utility interconnection queues. Shares closed up 14.4% Thursday in a broad operator rally that also lifted RIOT (Riot Platforms, Inc.) and HIVE (HIVE Digital Technologies Ltd.).

FLEX (Flex Ltd.)'s $4.4 billion acquisition of EPC Power could deepen competition in data center power conversion. Power systems companies such as ETN (Eaton Corporation plc) and VRT (Vertiv Holdings Co.) operate in adjacent power distribution and thermal management markets and may face evolving competitive dynamics, though no direct relationship to the EPC Power deal is confirmed.
CWK (Cushman & Wakefield plc)'s 21% per-MW construction cost increase could pressure margins for data center developers and hyperscalers building new capacity. Construction and project management firms that handle data center fit-out and power delivery could see pricing power, though no direct relationships are confirmed.
CIFR (Cipher Mining Inc.)'s bring-your-own-generation pipeline development could point to increased demand for power generation equipment. Gas turbine and fuel cell providers such as GEV (GE Vernova Inc.) and BE (Bloom Energy Corporation) operate in markets that could serve BYOG data center arrangements, though no direct relationship to Cipher is confirmed.
On watch

ORCL (Oracle Corporation) reports fiscal Q1 results on Thursday, September 10, with an EPS estimate of $1.74. Oracle is a critical readout for cloud infrastructure demand, given the company's direct data center expansion tied to AI compute availability. One confirmed linkage: AAOI (Applied Optoelectronics, Inc.) is a documented supplier to Oracle. Oracle's capital expenditure and capacity commentary will be the key data point for the optical interconnect supply chain.

ABM (ABM Industries Inc.) reports Tuesday, September 8, with an EPS estimate of $1.01. As a facility services provider with data center customers, ABM's results and backlog commentary could offer a read on operational spending at data center facilities. Documented competitors in the energy services and facility services markets include AMRC (Ameresco, Inc.) and EME (EMCOR Group, Inc.), and their shares could react to ABM's margin and demand commentary.

OCC (Optical Cable Corporation) reports Thursday, September 10, with an EPS estimate of $0.20. Optical Cable operates in fiber optic cabling and connectivity, a niche within the networking supply chain that feeds data center physical layer deployments. The report lands the same day as Oracle's, and both will provide complementary reads on AI network buildout activity.
