Saba Capital Management, L.P., Saba Capital Management GP, LLC and Boaz R. Weinstein filed Amendment No. 18 to Schedule 13D on Nuveen Multi-Asset Income Fund (symbol NMAI) dated 08/04/2025.

The group now beneficially owns 1,640,810 common shares, representing 4.91 % of the 33,425,645 shares outstanding reported in the issuer’s 3/4/25 DEF 14A. All voting and dispositive power is shared; none is held solely. Item 5(e) lists 07/29/2025, the date the reporting persons fell below the 5 % ownership threshold that normally triggers full 13D disclosure obligations.

Approximately $21.26 million of investor capital and ordinary-course margin borrowings were used to acquire the position (Item 3). The amendment updates Items 3, 5 and 7; it states “Purpose of Transaction: Not Applicable,� providing no new strategic intentions. Funds and accounts advised by Saba Capital retain rights to dividends and sale proceeds. Signatures were executed by Michael D’Angelo, General Counsel, on behalf of all reporting parties.

Positive
  • Saba retains a sizable 1.64 million-share stake, keeping it a top holder and potential influencer.
  • $21.3 million cost basis disclosure demonstrates meaningful, long-standing capital commitment to NMAI.
Negative
  • Ownership fell below the 5 % threshold, lessening Saba’s mandatory reporting and perceived activist pressure.
  • No strategic purpose disclosed, leaving investors without insight into future engagement plans.

Insights

TL;DR: Stake cut to 4.9%; activism potential moderates—overall neutral impact.

Saba’s ownership in NMAI recedes just under the 5 % threshold, a level that lessens regulatory reporting and may reduce its leverage in future shareholder initiatives. However, the firm still controls nearly 1.64 million shares, keeping it among the fund’s largest holders. With no stated purpose and no change in voting power structure, the filing mainly signals position-sizing rather than a strategic pivot. For investors, the news neither adds fresh catalysts nor raises operational risks, leaving the valuation narrative largely unchanged.

TL;DR: Dropping below 5 % weakens activist pressure—slightly negative for discount-closure thesis.

NMAI trades at a persistent discount; Saba’s historic activism was a key rerating hope. By trimming below 5 %, Saba eases continuous 13D scrutiny and signals diminished commitment to push for structural changes such as tender offers or conversions. The absence of a “purpose� statement underscores this retreat. While the position is not exited, probability of value-unlocking campaigns declines, marginally negative for investors expecting an activist catalyst.
