Bel Fuse Inc /NJ is a single operating company that trades on Nasdaq in two distinct share classes, and BELFB is the larger and more liquid of the two. Class A shares trade under the ticker BELFA and carry ten votes per share, while Class B shares trade under the ticker BELFB and carry one vote per share. Both classes represent identical claims on the same underlying cash flows, the same manufacturing footprint, and the same product portfolio, but the voting power gap is wide enough to create a persistent price differential. The Bernstein family, which founded the company in 1949, controls voting outcomes through its concentrated holding of Class A stock. Investors who buy BELFB are buying pure economic exposure to the underlying electronic-components business without paying the premium that the market attaches to voting control.
The underlying business is firing on all cylinders. Net sales in the second quarter of fiscal 2026 reached $210.7 million, a 25 percent increase over the $168.3 million reported in the second quarter of fiscal 2025. Net sales for the first half of fiscal 2026 totaled $389.2 million, a 21 percent increase over the $320.5 million reported in the first half of fiscal 2025. Gross profit in the second quarter came in at $84.0 million, up from $65.1 million in the year-ago quarter. The gross margin held at 39 percent, a level that reflects the company’s mix of power-conversion, magnetics, circuit-protection, and connectivity products aimed at industrial, networking, telecommunications, military, aerospace, and e-mobility end markets.
The dual-class structure is the single most important fact for prospective BELFB investors. Class A weighted-average basic shares for the quarter were 2.115 million, while Class B weighted-average basic shares were 11.483 million. The Bernstein family holds essentially all of the Class A float, and the Class B float is the part that trades freely in the public market. Class B holders have no meaningful ability to influence board composition, executive succession, or the timing and structure of any sale, merger, or recapitalization. The economic interest, however, is one-for-one with Class A on a per-share basis because both classes receive identical dividends when declared and share pro rata in any liquidation. The market consistently prices BELFB at a discount to BELFA to compensate for the lack of voting power, and that discount tends to widen in environments where the controlling family is more likely to act unilaterally and narrow in environments where the family is seen as a stable, value-aligned steward of capital.
For most institutional and retail investors, BELFB is the practical way to own the operating business. The Class B share count is roughly 5.4 times the Class A share count, which means daily trading liquidity, options market depth, and borrow availability are concentrated in BELFB. The Class A shares are tightly held and trade infrequently, which makes the apparent price of BELFA less reliable as a reference point and makes BELFB the natural vehicle for portfolio managers who want exposure to a mid-cap, US-domiciled, founder-controlled electronic-components manufacturer with a diversified end-market footprint.
The Bernstein family’s control has historically been a stabilizing factor rather than a value-destructive one. Bel Fuse has navigated multiple end-market cycles, has paid regular dividends, has made and integrated bolt-on acquisitions, and has invested in capacity in lower-cost geographies to defend margins. The risk that the family could use its voting control to block a take-private premium, to issue additional Class A shares, or to pursue a value-destructive related-party transaction is real and is the structural reason the Class B discount exists. The reward is that a long-term BELFB holder benefits from the same operating upside as a BELFA holder, with the discount providing a margin of safety if control-related frictions ever resolve in shareholders’ favor.
The current setup rewards investors who are comfortable separating economic exposure from voting influence. With first-half revenue up 21 percent year over year, gross margin holding at 39 percent, and a clean dual-class structure that maps cleanly to either a control-premium strategy (BELFA) or a pure-economic-exposure strategy (BELFB), the company offers a textbook example of how a dual-listed equity should be analyzed. The narrative for BELFB is straightforward: same operating company as BELFA, same factory output, same customer base, same cash flow, but priced lower because the buyer has no vote. Whether that discount is too wide, too narrow, or about right depends on how an investor weighs the stability of family control against the permanent loss of influence.
