# Weekly Recap | Nuburu -60%, NYSE warning meets Tekne integration

## The Week

Nuburu (BURU) tumbled 60% this week to close at $0.236, against a 0.47% dip for the S&P 500 — underperforming by roughly 59.53 percentage points. The stock opened Monday at $0.6108 and slid through the week: $0.5541 on Monday, then $0.4602, $0.4355 and $0.4101 over the next three sessions before Friday’s sharp move to a low of $0.235, ending at $0.236. The week’s range was 62.59%, with the pattern clearly one of a one-way sell-off.

## Key Events

The company’s story this week ran on two tracks. Monday’s 9.32% pre-market pop faded after Nuburu clarified that its 15 October share resale filing raised no new capital. On Tuesday, the company said it had received an NYSE American warning letter on disclosure requirements, with Wednesday’s headlines specifying the letter related to delayed disclosure of material events. The Tekne integration was the second thread: on Wednesday Nuburu reported execution progress on Tekne’s $17.1 million special-vehicle programme, and on Thursday it announced plans to integrate Tekne into its defence and security platform, naming Gianluca Trezza as TEKNE CEO. Friday brought another intraday slide of nearly 17% on the warning letter, alongside an EFFECT filing and, after the week’s close, a 424B3 prospectus.

## The Week Ahead

The macro calendar is heavy next week, led by Tuesday’s durable goods orders, FHFA house prices, Case Shiller 20-city index, new home sales, Richmond Fed composite and consumer confidence. On the company side, Nuburu’s fiscal Q3 2026 results are scheduled for 13 November after the close, leaving a quiet stretch before earnings. The focus will be on any follow-up to the NYSE American warning letter and further updates around the Tekne integration and special-vehicle programme.

## In Short

The week’s sell-off arrived alongside a dense flow of company news: tangible progress on the Tekne acquisition and platform build-out on one side, and an NYSE American warning over delayed disclosures on the other. The stock trades at about 5.8x book value with negative earnings, while the latest session’s money flow shows large-lot net selling and a split among smaller participants. What to watch now is whether the company can close the disclosure gap and whether the defence and security platform turns into firmer project-level signals.
